Detailed Description

The following specific examples are given by way of illustration only and not by way of limitation, and it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made in the examples without inventive faculty, and yet still be protected by the scope of the claims.

In fig. 1, a bed board 1 of an operating table for lateral position breast puncture is a long board adapted to a human body, and the bed board 1 is set horizontally in this embodiment, and it is specified that one end of the bed board 1 corresponding to the head of the human body is the rear, one end corresponding to the feet of the human body is the front, and it is specified that both sides of the bed board 1 are the left and right sides. In addition, since the arm placing device 2 is mainly used for placing the arms of the patient in the lateral position, which are positioned below the body, in the two arms of the patient in the lateral position, the arms mentioned herein refer to the arms of the patient in the lateral position, which are positioned below the body in the two arms. It is default here that in actual use there is a support member that lifts the bed board 1 half empty and there is room for the tie plate 22 to rotate down under the arm support 2.

Fig. 1 shows that the operating bed for lateral position breast puncture of the present invention comprises a bed plate 1 and an arm placing device 2, and the arm placing device 2 is located within the integral frame range of the bed plate 1, rather than being directly installed on the edges of the left and right sides of the bed plate 1 to make itself integrally protruded outside the bed plate 1, so that the space resources occupied by the whole medical bed are saved, and the inconvenience of the arm placing device 2 to doctors and patients is effectively reduced. In order to enable the arm placing device 2 to be located within the overall frame range of the bed board 1, in this embodiment, an accommodating groove 11 for accommodating the arm placing device 2 is provided on the left side and/or the right side of the bed board 1, and if the arm placing in the left side lying position or the right side lying position needs to be met, the accommodating groove 11 is provided on the left side or the right side of the bed board 1; if the arm when needs can satisfy left side position and right side position simultaneously is placed, then the left side and the right side of bed board 1 all set up holding tank 11. The accommodating groove 11 is located in the whole frame range of the bed board 1, and the accommodating groove 11 can be reserved at a corresponding position when the bed board 1 is processed and manufactured. Since the pad 22 in the arm rest device 2 occupies most of the space in the receiving groove 11, the position of the receiving groove 11 mainly corresponds to the position of the pad 22, and the pad 22 is a part directly supporting the arm of the patient, which should substantially cover the range from the shoulder to the waist of the human body in the front-back direction, and therefore the receiving groove 11 should also substantially extend from the shoulder to the waist of the human body in the front-back direction; the width of the pad 1 in the left-right direction is not limited too much, and in this embodiment, the width is preferably about 1-3 times of the width of the arm of the human body, and the width of the accommodating groove 11 in the left-right direction corresponds to the pad. Of course, since the backing plate 22 needs to rotate in the up-and-down direction, although the shape and size of the receiving groove 11 correspond to the backing plate 22, the size of the receiving groove 11 needs to be slightly larger than the size of the backing plate 22, so that a certain gap exists between the backing plate 22 and the bed board 1, and the backing plate 22 is prevented from rotating downwards due to too tight contact therebetween. The accommodation groove 11 extends from the shoulder to the waist of the patient in the front-back direction, so that when the cushion plate 22 rotates to the lower side of the bed plate 1, the arms of the patient in the lateral position are placed on the cushion plate 22 in a downward hanging manner, the parts of the patient from the shoulder to the waist are all located above the accommodation groove 11, and are in an unsupported suspended state, and the head and the waist of the patient are still supported by the bed plate 1. Compare in prior art patient need lie on one's side at the edge of bed board 1 so that hang down to arm strutting arrangement 2 with the arm from the bed board 1 outside, patient's back arm that lies on one's side can hang down to naturally in this embodiment on backing plate 22, and need not to follow the outside of bed board 1 is flagging, has guaranteed the travelling comfort that patient's arm was placed, also makes patient need not to lie on one's side at the edge of bed board 1, has got rid of patient and has rolled the hidden danger that gets off from bed board 1, has guaranteed the safety when patient lies on one's side.

The rotating part 21 of the backing plate 22 can be installed at the front end of the accommodating groove 11 in the front-back direction and also can be installed at the rear end of the accommodating groove 11, namely, the backing plate 22 has two modes of supporting the arm of the patient, namely, the front end of the backing plate 22 rotates downwards around the rear end, and the rear end of the backing plate 22 rotates downwards around the front end. If the first method is adopted, the whole arm of the patient placed on the backing plate 22 is attached to the backing plate 22 in an inclined manner, and the upper arm and the shoulder are close to the rotating part 21, so that the upper arm cannot naturally droop, and the chest cannot be well stretched. If the second mode is selected, an angle is opened between the cushion plate 22 and the bed plate 1, the distance between each part of the cushion plate 22 and the bed plate 1 decreases gradually from the rear end to the front end of the cushion plate 22, the shoulders of the patient approximately correspond to the rear end of the cushion plate 22, the upper arm of the patient can naturally droop from the position, then the elbow joint bends to enable the lower arm to be placed on the cushion plate 22, the upper arm is approximately vertical in the naturally drooping state, the body of the patient is approximately horizontal under the support of the bed plate 1, so that the upper arm is approximately vertical to the body, the chest is prevented from being extruded by the upper arm, the shoulder is further pulled towards the outer side of the body by the upper arm extending outwards, the extrusion of the shoulder to the chest is effectively reduced, and the chest is fully expanded. Therefore, the second mode is preferable in this embodiment, that is, the rotating part 21 is mounted at the front end of the accommodating groove 11.

Further, in this embodiment, an extending groove 12 is further disposed at a position adjacent to the rear portion of the accommodating groove 11 on the bed plate 1, the extending groove 12 is communicated with the accommodating groove 11, the two are communicated to form a whole body in an L shape, and the extending groove 12 approximately corresponds to the position of the shoulder of the patient. In the original solution, the size of the receiving slot 11 in the front-back direction is large, the patient cannot be supported from the shoulder to the waist, and in practice, the arm placed on the arm supporting device 2 may need to apply pressure to the pad 22 to obtain a reaction force to increase the support for the body, which puts higher demands on the strength of the supporting structure 23, and inevitably increases the cost of the supporting structure 23. After the extension groove 12 is preferably arranged in this embodiment, the position of the patient lying on one side can be moved from the position above the accommodating groove 11 to the position above the extension groove 12 in the original scheme along the left-right direction, so that the patient is further far away from the edge of the bed plate 1, and the hidden danger that the patient rolls down from the bed plate 1 is further reduced. Meanwhile, since the size of the extension groove 12 in the front-back direction is much smaller than that of the receiving groove 11 in the front-back direction, when the lateral position of the patient moves, the suspension area under the body of the patient is changed from the receiving groove 11 to the extension groove 12, the suspension area is greatly reduced, in other words, the supporting area of the bed plate 1 on the body of the patient is greatly increased, so that the patient can be more comfortable when lying on the side, and the arm is not required to apply pressure to the cushion plate 22 to increase the support on the body, thereby reducing the physical consumption of the patient and the strength requirement of the supporting structure 23. When a patient lies on the bed board provided with the extension grooves 12 on one side, the shoulders of the patient are approximately positioned above the extension grooves 12, the patient can extend the upper arms from the extension grooves 12 to the lower part of the bed board 1, and then the arms are obliquely placed on the base plate 22 slightly outwards.

In a further improvement, the backing plate 22 further has a protrusion 221 capable of being correspondingly disposed in the protruding groove 12, the shape of the protrusion 221 is identical to that of the protruding groove 12, and the size of the protrusion 221 is slightly smaller than that of the protruding groove 12, so that a certain gap exists between the backing plate and the bed plate to prevent the protrusion 221 from leaving the protruding groove 12 due to the close contact therebetween. The backing plate 22 with the protruding portion 221 is also L-shaped, in practical use, the backing plate 22 without the protruding portion 221 can already meet the requirement of placing the arm of the patient, but in this embodiment, the rotation of the backing plate 22 needs to be manually pushed, and the arm supporting device 2 further comprises a supporting structure 23 for maintaining the position of the backing plate 22, when the backing plate 22 is manually pushed to rotate, the supporting structure 23 needs to be overcome to support the backing plate to do work, the pushing force which needs to be applied is usually large, the backing plate 22 is simple in structure, no appropriate stress point exists on the backing plate, and if the protruding portion is arranged on the backing plate, the protruding portion 221 can serve as a handle for manually applying force to the backing plate 22, so that manual force application is facilitated, and the physical strength of a force applicator is saved. In addition, when the backing plate 22 is located in the receiving groove 11, the entire hospital bed can be used as a normal hospital bed for patients, the protruding groove 12 is hollow up and down, and the body part corresponding to the protruding groove 12 cannot be supported when the patient lies down, which may cause inconvenience to the normal use of the patient and may also affect the appearance, and the protrusion 221 can be filled in the protruding groove 12 to make up for the above-mentioned disadvantages.

The base plate 22 is rotated relative to the bed plate 1 by the rotating portion 21, the rotating portion 21 may adopt a common hinge structure, and when the base plate 22 is rotated to a proper position, a supporting mechanism 23 is further required to maintain the position of the base plate 22, and the supporting force of the supporting mechanism 23 on the base plate 22 should be able to resist the sum of the self weight of the base plate 22 and the pressure of the arm of the patient on the base plate 22. If the supporting force of the supporting structure 23 to the backing plate 22 is very large, the above requirements can be met certainly, but considering that the backing plate 22 may need to be overcome to do work when being manually pushed to rotate, the above supporting force needs to be overcome by a single person to apply force manually, so that the above supporting force needs to meet two conditions at the same time, and is analyzed specifically according to the characteristics of the supporting structure. In this embodiment, it is preferable that the supporting structure 23 is a first damping rotating shaft 24 installed in the rotating portion 21, when the bed board 1 adopts a scheme with the extending groove 12, the bed board 1 well supports the body of the patient, the patient only places the arm on the cushion board 22, and the force is not applied to the cushion board 22 in normal use, so that the supporting force required by the cushion board 22 is small, the resistance generated by the first damping rotating shaft 24 to the rotating portion 21 is enough to enable the cushion board 22 to be maintained at a certain position without rotating, and the resistance is also enough to be easily overcome when the single person applies the force to the cushion board 22. The first damping rotating shaft 24 is adopted to further facilitate the use of the arm placing device 2, and the user can push the rear end of the arm placing device to rotate downwards to any required position by applying force to the backing plate 22, so that the rear end of the arm placing device can rotate downwards within the range of 0-90 degrees in practical use. The second embodiment of the supporting structure 23 includes a supporting member 231 having one end rotatably mounted on the inward side of the base plate 22 and a plurality of fixing posts 232 arranged in the front-rear direction on the bed plate 1 and facing the base plate 22, the other end of the supporting member 231 is provided with a positioning sleeve 233 for the fixing posts 232 to pass through, and the front end of the supporting member 231 is rotatably mounted on the base plate 22 and the rear end thereof is provided with the positioning sleeve 233. When the backing plate 22 is in the initial position, the front end and the rear end of the supporting element 231 are kept horizontal, the positioning sleeve 233 is matched with the positioning column 232 at the rearmost end, one end of the supporting element 231 pulls the fixing column 232 at the rearmost end, and the other end pulls the hinge joint of the supporting element 231 and the backing plate 22, so that the backing plate 22 is kept horizontal; when the backing plate 22 needs to be rotated downwards, the positioning sleeve 233 is separated from the fixing column 232, the backing plate 22 is rotated to a certain position, and then the positioning sleeve 233 on the supporting element 231 is matched with the positioning column 232 at the corresponding position, so that the supporting structure is stable, the backing plate 22 can be effectively prevented from rotating downwards as long as the strength of the material is enough, but the position of the supporting element 231 needs to be manually adjusted in use, and the supporting structure is complex. With reference to the above two embodiments, a third embodiment of the supporting structure 23 may be designed, that is, the matching between the positioning sleeve 233 and the fixing column 232 in the second embodiment is changed to the matching between a sliding block and a sliding rail, the sliding rail is disposed at the position where the fixing columns 232 are arranged in the original scheme, the sliding block is disposed at the position of the positioning sleeve 233 in the original scheme, the sliding block is rotatably connected to the supporting element 231, the sliding block is integrally disposed on the sliding rail, and the sliding block is slidably connected to the sliding rail with damping. When the backing plate 22 rotates downward, the end of the supporting element 231 connected to the backing plate is driven to move downward, so as to generate a forward pulling force on the other end of the supporting element 231, the other end of the supporting element 231 is moved in the slide rail to realize position change, and the damping between the slide rail and the slide rail can maintain the position relationship.

When the patient uses the medical bed normally, the arms of the patient are placed on the backing plate 22, the arms do not exert force as much as possible, and the body of the patient is supported mainly by the bed plate 1. When the bed plate 1 does not have the extension groove 12, the shoulders to the waist of the patient body are suspended, and the head, the neck and the lower part of the waist are supported by the bed plate 1; when the bed board 1 is provided with the extending groove 12, the shoulders of the patient body are suspended, and the head, the neck and the lower part of the shoulders are supported by the bed board 1. In both cases, the patient's head and neck are subjected to a greater support force, and in particular in the first case, the patient's head and neck are subjected to greater pressure, which may cause discomfort to the patient and therefore need to be supported well in order to maintain a good posture. In the embodiment, a headrest device 3 specially used for supporting the head and neck of a patient is preferably arranged at the rear side of the bed plate 1, and comprises a pillow 31 and a height adjusting mechanism 32 for adjusting the height of the pillow 31, the pillow 31 can be adjusted to the required height in actual use so as to meet the requirements of patients with different body types, and in general, in order to keep the head and neck in a good posture to bear pressure, the neck is kept in a horizontal state, and then the pillow 31 is adjusted to the height capable of supporting the head to make the neck horizontal. In the embodiment shown in fig. 4, the height adjusting mechanism 32 preferably comprises two substantially parallel supporting plates 321, one end of the supporting plate 321 is rotatably connected to the rear side of the backing plate 22, and the other end is rotatably connected to the pillow 31, so that the height of the pillow 31 can be adjusted by rotating the supporting plate 321; mounting holes 322 are respectively arranged at the corresponding positions of the two support plates 321 in the vertical direction, a nut 324 with a pressing sheet 323 is placed in one mounting hole 322, the pressing sheet 323 is tightly attached to the support plates 321, a bolt 325 matched with the nut 324 is inserted into the other mounting hole 322, the bolt 325 and the nut 324 are screwed, the head of the bolt 325 is tightly attached to one support plate 321, the pressing sheet 323 of the nut 324 is tightly attached to the other support plate 321, and the two support plates 321 are locked in the vertical direction to fix the positions of the two support plates 321.

When the arm supporting devices 2 are arranged on the left side and the right side of the medical bed, a patient can adopt a left side lying position or a right side lying position according to needs, but the width of the bed plate 1 is often large under the condition, so that the width of the pillow 31 can adapt to the width of the bed plate 1, in order to save cost, the headrest device 3 preferably further comprises a moving mechanism 33 for driving the pillow 31 to move along the left-right direction, and only one pillow with a small size needs to be correspondingly arranged. When the patient is in the left recumbent position, the pillow 31 is moved to the left area; when the patient is in the right side lying position, the pillow 31 is moved to the right side area, and the cost of the pillow 31 is effectively saved. In this embodiment, the moving mechanism 33 preferably includes a support 331 and at least two sliding rods 334 fixed below the pillow 31, the two sliding rods 334 are parallel to each other and extend in the left-right direction, the support 331 has support plates 332 on the left and right sides, the support plates 332 are provided with limiting holes 333 through which the sliding rods 334 pass, and the pillow 31 is mounted on the support plates 332 through the sliding rods 334 and can move in the limiting holes 333 in the left-right direction. After the moving mechanism 33 is added, the height adjusting mechanism 32 is directly connected with the pillow 31 in a rotating way from the original scheme to realize indirect rotating connection with the pillow 31 through the rotating connection with the support 331.

In use, the posture of the patient in the lateral recumbent position is difficult to maintain for a long time, and usually needs to be maintained by external force, and in the embodiment shown in fig. 2, a support rod 25 is preferably rotatably mounted on the outer side of the base plate 22 through a second damping rotating shaft 26, and the support rod 25 can rotate in the up-and-down direction. When the patient adopts the left lateral decubitus or the right lateral decubitus, the backing plate 22 on the other side is still in the initial state, the supporting rod 25 on the backing plate 22 can be rotated upwards to be in a generally vertical shape, and then supports such as a back cushion and the like can be placed between the supporting rod 25 and the back of the patient to fill the space between the supporting rod and the back of the patient, so that the back of the patient is fully supported, and the posture of the lateral decubitus is kept for a long time.
