Description

An auxiliary patient ferrying device

technical field

The invention relates to the technical field of medical equipment, in particular to an auxiliary patient ferrying device.

Background technique

Social aging, cardiovascular and cerebrovascular diseases, trauma and other factors can lead to a large number of patients with motor dysfunction. The escort assists the patient to transfer between the bed (or examination bed) and the wheelchair (or chair), which requires not only certain skills but also considerable strength. In particular, heavy patients often require the cooperation of multiple people, and there is a greater risk of falling and knocking injuries during the transfer process. In addition, in hospitals, wheelchairs are the main means of transportation for critically ill patients or patients with movement disorders. When perfecting the examination, the patient needs to frequently transfer between the wheelchair and various examination beds many times. Realizing the safe, convenient, easy and efficient transfer of patients between wheelchairs and examination beds not only greatly reduces the labor intensity of nurses and accompanying staff, but also greatly saves medical resources and reduces the economic burden of patients and their families.

Described lifting mechanism 2 utilizes forklift type lifting mechanism 2 to design and form, compares with other adopting scissors type lifting mechanism 2, and its scissor type lifting mechanism 2 takes up volume big, and whole structure is also more complicated, and scissors The lifting height of the type lifting height is achieved by changing the stroke on the bottom plate. The lifting range is limited. Although the number of cross-connecting rods can be used to obtain the ideal lifting height, each connecting rod is connected in a hinged manner, so that the entire structure does not Compact, low reliability, short service life. And the present invention adopts the lifting mechanism 2 of forklift formula, and structure is simple, and it takes up little space, and more importantly, there is a relatively large gap between the auxiliary ferry mechanism 3 and the base 11 of the mobile vehicle mechanism 1, through which the base 11 can be Inserting under the sickbed means placing most of the auxiliary ferry mechanism 3 on the sickbed, so that the patient can be transferred at the center of the sickbed, which is safe and will not fall. And if adopt traditional scissor lift mechanism 2, because scissor lift mechanism 2 occupies a large amount of space between auxiliary ferry mechanism 3 and the base plate 32 of mobile car mechanism 1, base 11 can not be directly inserted under the hospital bed, and auxiliary ferry Mechanism 3 is only in conflict with ferry transfer at the edge of the hospital bed. However, when the patient is ferried and transferred at the edge of the hospital bed, due to the unstable center of gravity, it is easy to fall, which cannot guarantee the safety of the patient, and may even cause medical disputes.

The lifting mechanism 2 includes a fixed column 21, a lifting slide rail 22, a lifting screw mandrel 23, and a lifting power device 24; synchronous movement, and the connecting plates 25 of the slide rails at both ends are fixed on the base plate 32 of the auxiliary ferry mechanism 3, thereby realizing the height adjustment of the auxiliary ferry mechanism 3.

Described auxiliary ferry mechanism 3 comprises base plate 32, ferry belt 33, rotating shaft seat 31, rotating shaft 34, protective sleeve, forward and reverse drive motor; Described base plate 32 is used for supporting and connecting other parts of auxiliary ferry mechanism 3 on the one hand, on the other hand On the one hand, the bottom plate 32 is embedded on the connecting plate 25 of the lifting mechanism 2 and has the effect of a bridge link, so that the auxiliary ferry mechanism 3 can move up and down; The output shaft of the rotating drive motor is connected. During use, when the forward and reverse drive motor rotates forward, the ferry belt 33 moves in a certain direction, and when the forward and reverse drive motor reverses, the ferry belt 33 moves in the opposite direction. That is, the forward movement and reverse movement of the ferry belt 33 can be realized. Thereby completing the transfer of the patient between the hospital bed and the examination bed; the protective cover is provided with a raised portion 361 and an arc portion 362, the purpose of which is to prevent the ferry belt 33 from injuring the user, and the setting of the raised portion 361 makes the arc portion 362 There is a gap with the rotating shaft 34, so that the ferry belt 33 passes through.

An auxiliary patient ferrying device of the present invention can quickly move the elderly to the hospital bed or examination bed without lifting the elderly in the wheelchair. The operation is simple and safe, and the physical safety of the elderly is ensured. Organically combined with the lifting mechanism 2, the user straddles the auxiliary ferry mechanism 3, adjusts the height of the auxiliary ferry mechanism 3 to be equal to or slightly higher than the wheelchair through the lifting mechanism 2, and the user moves from the wheelchair to the auxiliary ferry mechanism 3 , drive the ferry belt 33 to rotate, move the user to the middle of the auxiliary ferry mechanism 3, move the present invention to the front of the bed or the front and back of the examination bed, and adjust the height of the auxiliary ferry mechanism 3 to be equal to or slightly higher than the height of the hospital bed or examination bed , reversely rotate the ferry belt 33 to move the user to the hospital bed or examination bed, and the user moves from the auxiliary ferry mechanism 3 to the hospital bed or examination bed. It greatly reduces the work intensity of nursing staff, effectively protects the personal safety of users, and improves the transfer efficiency of wheelchair users between hospital beds or examination beds; it is equipped with a forklift-type lifting mechanism 2, which is simple in structure and takes up little space. A large gap is reserved between the auxiliary ferry mechanism 3 and the base 11 of the mobile vehicle mechanism 1, through which the base 11 can be inserted under the hospital bed, that is, the majority of the auxiliary ferry mechanism 3 is placed on the hospital bed, so that the patient is immediately on the hospital bed. The transfer of the ferry can be realized at the center, which is safe and will not fall; it is equipped with an automatic controller 16, and the forward and backward, steering and locking of the entire ferry device can be realized through the matching remote control, with a high degree of automation and convenient operation. The patient can operate alone, which is conducive to saving human resources in the hospital. The column rod 13 is movably connected in the chute 18 and pushed from the front side of the patient to the rear side, and the armrest frame 15 on the column rod 13 is rotated 180 degrees, thereby better The bottom plate 32 is provided with an opening 17, which can be directly inserted on both sides of the toilet, which is convenient for the patient to defecate; To harm the user, the protruding portion 361 is set so that there is a gap between the arc portion 362 and the rotating shaft 34, so that the ferry belt 33 passes through.

The above is only a preferred embodiment of the present invention, it should be pointed out that for those of ordinary skill in the art, without departing from the method of the present invention, some improvements and supplements can also be made, and these improvements and supplements should also be considered Be the protection scope of the present invention.
