Description

Device for transferring patient

Technical Field

Background

At present, after the operation of a hospital, a patient needs to be transferred from an operating room to other wards for observation. Firstly, a patient is transferred from an operating table of an operating room to a wheelchair or a wheeled sickbed and pushed to a sickroom, and then transferred to the sickbed of the sickroom from the wheelchair or the wheeled sickbed. Because the patient has a wound after operation and cannot move by himself, the patient transfer is mostly completed by medical care personnel or accompanying family members. The strength of the transfer person is small, and the individual difference of the transferred person is large, such as the weight, the wound position and the like, so that the transfer patient is inconvenient at present due to the cooperation of a plurality of persons.

There are also a plurality of beds for transferring patients in the prior art, such as a carrying bed and a carrying method disclosed in patent CN112057240A for facilitating the transfer of patients. The carrying bed needs the patient to be matched with the carrying bed from side standing to lying, and although the carrying can be completed by one person through the matching of the lifter and the left and right beds, the carrying bed can not solve the carrying problem when the patient can not be matched with side standing.

Patent CN112006854A provides a better solution, a transfer vehicle with a belt, which can scoop up a patient and transfer the patient to the transfer vehicle via the belt, and which is further provided with a lap joint in order to prevent the carrying of bedding, clothing, etc. However, although this transfer cart is provided with only a lifting device and a mechanism for extending the panel, which can solve the problem of scooping up the patient, the horizontal panel increases the contact area with the bedding relatively, and even if the lap joint portion is provided, the risk of rolling up the bedding due to the rotation of the belt is increased. And CN112006854A mainly solves the problem that the patient can not be parallel to the transfer cart, so two bed surfaces are arranged, and a first winding drum and a second winding drum are further arranged to realize the function of winding and unwinding the transmission belt, so that the structure of the transfer cart is complex.

In order to solve the current situation that the patient is transferred in the hospital at present and is still practical and manpower, the device for transferring the patient is provided, the structure of the device is simple, and the efficiency for transferring the patient is higher.

The working principle is as follows: the human body 8 is positioned on a sickbed 6 paved with bedding 7 or soft covering and waits for transfer; the device is arranged on one side of a sickbed 6, the device is provided with a storage battery 14, and the power can be independently supplied by an external power supply or the storage battery 14. One side of the side guard rail 54 is close to the sickbed 6, the side guard rail 54 is put down, and the side support can be formed after the side guard rail 54 is put down, so that the bed 31 is prevented from tipping over. The lifting mechanism 2 lifts the bed assembly 3 to ascend, and the bed assembly 3 ascends to be higher than a sickbed 6 where a patient is positioned; the translation structure drives the pinion 46 to drive the translation rack 45 to drive the third slide rail 44 and the second slide rail 43 to extend out relative to the first slide rail 42 through the translation motor 41, so as to push the bed assembly 3 to horizontally and transversely move, and when the rolling shaft 314 at the side of the bed assembly 3 moves to be right above the edge of the sickbed 6, the translation mechanism 4 stops working; the side-tipping mechanisms 32 at the two ends of the bed assembly 3 drive the bed assembly 3 to incline downwards by a certain angle towards the side of the patient; the lifting mechanism 2 slowly puts down the bed assembly 3, and the lifter stops working after the guard plate 313 below the side roller 314 and the bed sheet 7 of the sickbed 6 are compressed to a certain height; the translation mechanism 4 starts to work to push the bed assembly 3 to move horizontally towards the patient, meanwhile, the hoisting motor 339 starts to work to drive the composite conveyor belt 316 to rotate clockwise around the bed base plate 311, and the linear speed of the rotation of the composite conveyor belt 316 is equal to the horizontal and horizontal moving speed of the translation mechanism 4 pushing the bed assembly 3. When the composite belt 316 contacts the body of the patient, the contact part of the composite belt 316 with the human body 8 is moved upward relative to the human body 8, so that the contact part of the patient with the composite belt 316 is moved to the bed 31 together with the composite belt 316. The bed 31 body can smoothly move to the lower part of the patient body in the horizontal movement process to support the patient body. As the body of the bed 31 is gradually inserted with the translation mechanism 4 between the patient and the bed 6 bedding 7, the patient is gradually transferred to the bed assembly 3. When the body of the bed 31 is inserted between the patient and the bedding 7 of the sickbed 6, the horizontal speed of the body of the bed 31 is equal to the linear speed of the composite conveyor belt 316, so that the patient can be prevented from being pulled relative to the sickbed 6 in the process of transferring to the body of the bed 31, and the patient is prevented from being injured.

When the human body is transferred from the bed assembly to the sickbed paved with the soft covering, the sequence is opposite to the above actions.

Finally, the above embodiments are only for illustrating the technical solutions of the present invention and not for limiting, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all of them should be covered in the claims of the present invention.
