Detailed Description

In order that the manner in which the above-recited features, advantages, objects and advantages of the present invention are obtained, a more particular description of the invention briefly summarized above may be had by reference to the embodiments thereof which are illustrated in the appended drawings. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

In order to overcome the defects in the prior art, as shown in fig. 1 and 2, the invention provides an auxiliary lifting device for emergency rescue of obese patients, and a lifting mechanism 1 is detachably connected with a stretcher 2.

In the emergency rescue of the obese patient, the obese patient may need to be transported in emergency, and in this case, the obese patient needs to be placed on the stretcher 2, and then the stretcher 2 is lifted and moved to a proper position by the lifting mechanism 1.

Specifically, as shown in fig. 3, in the lifting mechanism 1 for an auxiliary lifting device for emergency rescue of an obese patient, two ends of a transverse frame 12 are respectively and fixedly connected to the ends of two base frames 11, and two hanging components 13 are both in sliding connection with the transverse frame 12.

In the auxiliary lifting device for emergency rescue of the obese patient, through the lifting mechanism 1, the obese patient is firstly arranged on the stretcher 2 in the emergency transportation process of the obese patient, after the obese patient is arranged, two hanging components 13 are required to be adjusted to the proper positions based on the transverse frame 12 according to the proper positions to be hung, then the stretcher 2 is hung through the hanging components 13, and after the stretcher 2 is hung, an operator moves the whole device through the moving base frame 11.

The two side base frames 11 and the hanging component 13 in the middle are erected in a structure, so that the device can bear larger transverse and longitudinal loads, is suitable for hanging fat patients with larger weight, can effectively disperse bearing capacity, and can ensure that structural damage is not caused by overlarge load in the process of hanging the fat patients; in addition, the structure of the lifting mechanism 1 allows enough span to be convenient for operation under different space environments, for example, the lifting mechanism can be easily adapted to and complete lifting tasks in various occasions such as hospital wards, hallways, elevators and even outdoors;

It should be noted that the middle cross frame 12 can be designed to be telescopic or adjustable according to actual use requirements, so that the lifting mechanism 1 can flexibly adjust the width according to the specific position and the transfer route of the obese patient, and the convenience of operation can be further improved; in addition, because the two ends of the transverse frame 12 are connected with the ends of the two base frames 11, the formed closed stress system can provide omnibearing support and balanced stress by the mechanical design, the risk of patient injury in the lifting process is reduced, and the safe operation of medical staff is ensured.

Further, as shown in fig. 4, two ends of the reinforcing frame 112 are fixedly connected to two side sections of the tripod 111 respectively, of the base frame 11 in the auxiliary lifting mechanism 1 for emergency assistance of obese patients;

It should be noted that, the present invention is an auxiliary lifting device for emergency rescue of obese patients, through the base frame 11, after the stretcher 2 is lifted by the hanging component 13, the whole device needs to be moved by moving the base frame 11, in the moving process, the movement of the device is realized through four travelling wheels 113 arranged below two tripods 111, after moving to a suitable position, an operator can rotate the screw 114 based on the tripods 111, the screw 114 relatively moves based on the tripods 111 after rotating, and then the floor support 115 is driven to abut against the placing surface, so that the stable support of the base frame 11 can be realized.

Because the tripod 111 is of a triangle structure as a whole, the tripod 111 forms a firm supporting system among three supporting points, and can keep good stability even when a heavy obesity patient is lifted; and because of the structure of the tripod 111, the triangle structure can effectively disperse the force applied on the hanger, so as to disperse the huge pressure caused by the weight of the patient to all the fulcrums, and prevent the structural failure or damage caused by local overload; in addition, the triangular structure can resist torsion effect, reduce the risk of patient position change caused by uneven stress in the lifting process, and is beneficial to maintaining comfort and safety of patients;

Because the two groups of screw rods 114 and the ground support 115 are attached to the bottom end of the tripod 111, when an obese patient is lifted, the weight of the patient is large, the ground support 115 is not configured, so that the bottom of the hanging bracket can be tilted or the whole body can be turned over, and after the ground support is additionally arranged, the safety accidents can be effectively prevented even in the lifting and descending processes; and the adjustable ground support 115 can give the hanger additional supporting force on the ground, especially when dynamic load changes possibly occur in the lifting process, the ground support 115 can further ensure the stability of the whole structure.

the pulling member 133 is a wire rope.

It should be noted that, the present invention is an auxiliary lifting device for emergency rescue of obese patients, through the hanging assembly 13, in the process of hanging the stretcher 2, two carriages 131 are firstly slid to suitable positions based on the transverse frame 12, then two sets of traction members 133 are respectively released to a length equal to the height of the stretcher 2 through two windlass 132, then the hook 134 is hooked on the stretcher 2, and after that, the traction members 133 corresponding to the two carriages 131 are respectively driven to roll up again, so as to drive the stretcher 2 to vertically ascend, thereby realizing the hanging of the stretcher 2.

The sliding frames 131 are attached with fasteners, such as fasteners of a screw rotating connection brake block, or brake pieces commonly used in the market or well known to those skilled in the art, after the positions of the two sliding frames 131 are adjusted properly based on the transverse frame 12, the two sliding frames 131 need to be fastened to ensure the hooking stability of the two hooks 134;

The traction member 133 is preferably a wire rope or a steel chain, so as to ensure the lifting strength of the obese patient.

Specifically, as shown in fig. 5, the stretcher 2 for the auxiliary lifting device for emergency help of obese patients is characterized in that a guardrail 23 is fixedly connected to the outer edge above the bed body 21, the guardrail 23 shown in fig. 4 is arranged between the stretcher and the guardrail, two ends of the connecting component 22 are respectively detachably connected to two opposite guardrails 23, and a travelling wheel is also arranged below the bed body 21.

It should be noted that, in the auxiliary lifting device for emergency rescue of obese patients, the obese patients need to be arranged on the bed body 21 in the auxiliary lifting process of the obese patients through the stretcher bed 2;

In order to improve the rescue efficiency of the obese patient, the connecting component 22 is fixed on the two guardrails 23 on the bed body 21 in advance, and if uneven stress points of the stretcher bed 2 are encountered in the moving process, the hooking points of the lifting mechanism 1 need to be adjusted through the connecting component 22.

Further, as shown in fig. 6, the connection assembly 22 in the auxiliary hoist for emergency rescue of obese patients is detachably connected to two opposite guardrails 23 at both ends of the base bar 221, and two movable members 222 are adjustably fixed to the outer wall of the base bar 221, respectively.

It should be noted that, in the present invention, the connection assembly 22 is integrally installed between the two guardrails 23 based on the base rod 221 during the installation of the stretcher 2 through the connection assembly 22, and the two movable members 222 are adjusted based on the base rod 221 during the adjustment of the hanging stress point of the stretcher 2.

The two movable pieces 222 are distributed on the outer wall of the base rod 221 and are clamped and fixed in an adjustable manner, the movable pieces 222 arranged on the outer wall of the base rod 221 can adjust the relative stress points of the stretcher 2 according to the actual lifting demands of obese patients with different weight degrees, and because the two movable pieces 222 are flexibly arranged, the pressure can be effectively dispersed, and the potential safety hazard that local pressure is overlarge and skin injury or pressure sore is easily caused by a single stress point due to the fact that the weight of the obese patients is large is avoided; the flexible change of the stress points can enable medical staff to adjust and control the lifting device more easily, reduce the operation difficulty, reduce the physical consumption and improve the working efficiency; different stress points correspond to different body positions, and the stress points are flexibly adjusted, so that the body position of a patient can be changed in the lifting process, the patient is more comfortable, the body stability of the patient can be better maintained, and shaking or rotation caused by gravity center deviation is avoided; in addition, in complex environments such as narrow channels, stairways or special medical procedures, the lifting direction and path can be flexibly adjusted by changing the stress points, so that the device is suitable for field conditions and improves the transportation efficiency; furthermore, obese patients may have problems with dyspnea, blood circulation disorders, etc., and by properly altering the stress points, such as raising the head or legs, may help improve respiratory and hemodynamic status, preventing or alleviating potential complications.

Further, as shown in fig. 7, for the base rod 221 for the connection assembly 22 in the stretcher 2 for emergency help of obese patients, the installation bottom block 2211 is fixed on the guard rail 23 by a fixing piece such as a screw or a rivet, the rotation block 2212 is rotationally connected with the installation bottom block 2211, one end of the base rod 221 is fixedly connected with the rotation block 2212, the positioning block 2217 is fixedly connected with one end of the base rod 221 far away from the rotation block 2212, the base block 2213 is also fixedly connected with the outer wall of the guard rail 23 corresponding to the base rod 221, the structure is similar to the connection structure of the installation bottom block 2211 and the guard rail 23, the base block 2213 is provided with a positioning groove 2214, and the base block 2213 is matched with the structure of the positioning block 2217 based on the positioning groove 2214;

The clamping buckle 2216 is fixedly connected to two side sections of the positioning block 2217, the two spring clamping seats 2215 are respectively and fixedly connected to the left side and the right side of the positioning groove 2214 on the upper outer wall of the base block 2213, and the two groups of spring clamping seats 2215 and the clamping buckle 2216 are matched and used for fixing the positioning block 2217 and the base block 2213.

It should be noted that, in the present invention, the base rod 221 is provided, in the process of installing the base rod 221, the installation bottom block 2211 and the base block 2213 are fixed to the two guardrails 23 through the fixing member such as the screw or the rivet, then, in order to make the hook 134 be hooked to the movable member 222 more quickly, in the process of hooking the hook 134, the rotating block 2212 can be rotated based on the installation bottom block 2211, so that the rotating block 2212 drives the base rod 221 to rotate, so that the base rod 221 can be hooked closer to the hook 134;

After the hooking 134 is hooked, the base rod 221 needs to be stably reset, and the rotating block 2212 is rotated based on the mounting bottom block 2211 until the positioning block 2217 is completely engaged with the base block 2213 based on the positioning groove 2214, and in this process, two buckles 2216 attached to the positioning block 2217 are respectively and completely butted to two corresponding spring clamping seats 2215 to realize clamping;

in the same manner as above, in the process of setting or removing the obese patient, the rotation block 2212 is also required to be rotated so that the base 221 does not block the obese patient.

Because the rotating block 2212 rotates based on the mounting bottom block 2211, and one end of the base rod 221, which is far away from the rotating block 2212, is matched with the structure of the base block 2213 through the positioning block 2217 and the positioning groove 2214, in this process, the base block 2213 and the positioning block 2217 are clamped by the two groups of spring clamping seats 2215 and the clamping buckles 2216, so that the base rod 221 is quickly assembled and disassembled, and in an emergency state, for example, after the obese patient is transported, the connecting assembly 22 is not required to be integrally disassembled, one end of the base rod 221 is separated from the guardrail 23, so that the connecting assembly 22 does not block the obese patient, and the obese patient can be moved or placed from the bed body 21.

As a preferred embodiment, and as shown in fig. 8, for the movable member 222 for the connection assembly 22 in the stretcher 2 for emergency assistance of obese patients, the base sleeve 2221 is slidingly connected to the outer wall of the base rod 221, the opposite ends of the two springs 2224 are respectively and fixedly connected to the two ends of the base sleeve 2221, the different ends of the two springs 2224 are respectively and fixedly connected to the two fixing sheets 2225, the two fixing sheets 2225 are respectively and fixedly connected to the fixing sections of the corresponding clamping bands 2223, and the fixing sections of the two clamping bands 2223 are also fixedly connected to the opposite ends of the two damping bands 2222;

the two damping sleeves 2222 are made of soft rubber, so that the friction coefficient between the movable piece 222 and the base rod 221 can be further increased under the condition of no external force.

It should be noted that, in the process of hooking the hook 134 to the connection assembly 22 through the movable member 222, the hook 134 is hooked to the movable member 222 to achieve the hooking of the hook 134 to the connection assembly 22;

In this process, the hook 134 is hooked to the base sleeve 2221, and before the stretcher 2 is hooked, the position of the movable member 222 can be adjusted correspondingly with respect to the position to be hooked of the hook 134:

In the process of adjusting the position of the movable member 222, the two clamp bands 2223 are required to be loosened, so that the movable member 222 can slide based on the base rod 221 under the condition of external stress, thereby adjusting the position of the movable member 222, and after the position of the movable member 222 is adjusted properly, the two clamp bands 2223 are pressed tightly, so that the movable member 222 is integrally held tightly on the outer wall of the base rod 221.

As a preferred embodiment, based on the above, it will be understood by those skilled in the art that when the stretcher 2 is hooked, if an urgent adjustment is required to be made to the hooking points of the stretcher 2 in this state, the two clips 2223 may be released, and in this state, after the clips 2223 attached to the movable members 222 respectively abutted with the two hooks 134 are released, the base bar 221 may be moved based on the two base sleeves 2221, so that the two movable members 222 may be moved in cooperation with the two carriages 131, and a corresponding adjustment is made to the stress points of the stretcher 2.

In addition, in the hooking process, if the patient needs to perform inclined hooking, because the obese patient often has respiratory problems such as obstructive sleep apnea syndrome (OSAHS), the respiratory tract blockage may be aggravated by the falling of the tongue root and fat accumulation in the chest and abdomen during lying, and if the patient has dyspnea, the patient may need to change to a semi-sitting position or a slope position for transportation so as to improve respiratory tract patency, two traction pieces 133 need to be adjusted to different extension lengths, so that the stretcher 2 is hooked obliquely:

In the actual operation process, an operator rolls up the traction members 133 by driving the windlass 132 to which the two traction members 133 are respectively attached, so that the lengths of the two traction members 133 are suitable, and because the stretcher 2 is based on the relative inclination of the cross frame 12, in the hooking process of the hook 134 to the movable member 222, the hook 134 directly applies force to the base sleeve 2221, and the base sleeve 2221 forms deformation to the two springs 2224 based on the two fixing sheets 2225 respectively, so that the difference of the application points of the hook 134 to the movable member 222 is adapted, and the maximum stress balance of the movable member 222 can be effectively ensured.

The foregoing has shown and described the basic principles and main features of the present invention and the advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the foregoing embodiments, which have been described in the foregoing description merely illustrates the principles of the invention, and that various changes and modifications may be made therein without departing from the spirit and scope of the invention, which is defined in the appended claims.
