Description

Technical Field

[0001] This invention relates to an accessible patient transfer structure, and more particularly to an accessible patient transfer structure for use in the field of medical devices. Background Technology

[0002] When transferring patients with limited mobility, two main methods are generally used. The first method involves multiple medical staff transferring the patient by flipping and dragging their body. This method is inefficient for patients who are unable to move. The second method involves using mechanical equipment to place a flatbed between the patient and the bed, and then lifting the patient for transfer. However, when the flatbed is inserted between the patient and the bed, the friction between the flatbed and the patient and the bed is relatively large, which not only consumes more power but also causes discomfort to the patient and damages the bed. Summary of the Invention

[0003] The technical problem that this invention aims to solve in view of the above-mentioned prior art is that when the flat plate is inserted between the patient and the bed, the friction between the flat plate and the patient and the bed is relatively large, which not only consumes more power, but also causes discomfort to the patient and damages the bed.

[0004] To address the aforementioned problems, this invention provides an accessible patient transfer structure, comprising an outer frame, a bed frame fixedly connected to one end of the outer frame, multiple evenly distributed sliding grooves on the top of the bed frame, a movable groove on the lower side of the sliding grooves, a support plate slidably connected inside the sliding grooves, the support plate consisting of a load-bearing plate and a movable plate, the movable plate being fitted over the outside of the load-bearing plate and slidably connected thereto, an airbag fixedly connected to one end of the load-bearing plate, an air plug fixedly connected to one end of the movable plate, an air groove inside the load-bearing plate, a through hole communicating between the air groove and the airbag, a transmission block fixedly connected to one end of the movable plate, an air pump fixedly connected to one end of the bed frame, and a connecting pipe communicating between the air pump and multiple inflatable seats.

[0005] As a further improvement of this application, a row beam is slidably connected between the side walls on both sides of the outer frame, a longitudinal drive motor is fixedly connected to the outer wall of the outer frame, and a lead screw is fixedly connected to the output end of the longitudinal drive motor, and the lead screw passes through the row beam and is threadedly connected to it.

[0006] As a further improvement of this application, the two ends of the beam are fixedly connected to the hanging plates, and a double-acting screw is rotatably connected between the two hanging plates and a slide bar is fixedly connected between them. Two external blocks are provided between the slide bar and the double-acting screw. The external blocks are threadedly connected to the double-acting screw and slidably connected to the slide bar. The two external blocks are located at the positive and negative threads of the double-acting screw, respectively.

[0007] As a further improvement of this application, a horizontal drive motor is fixedly connected to the side wall of one of the hanging platforms, and the output end of the horizontal drive motor is fixedly connected to one end of a bidirectional lead screw.

[0008] As another improvement of this application, an electromagnet is fixedly connected to one end of each of the two external blocks, and the transmission block is made of iron material; with the above setting, when the patient is put down, the electromagnet can be activated to attract the transmission block to pull back the multiple support plates in sequence.

[0009] As a further improvement to this application, the load-bearing plate has an inner staggered hole at one end inside the movable plate, and an outer staggered hole at one end of the movable plate; through the above arrangement, the frictional force when the support plate is separated from the patient can be reduced, further improving the patient's comfort.

[0010] As a further improvement to this application, an inner limiting block is fixedly connected to the inner wall of the movable plate, and an outer limiting sleeve is fixedly connected to one end of the movable plate. The outer limiting sleeve is fitted on the outside of the load-bearing plate, and an outer limiting block is fixedly connected to one end of the load-bearing plate. The outer limiting block is located inside the outer limiting sleeve. Through the above arrangement, the displacement between the load-bearing plate and the movable plate can be limited.

[0011] In summary, when transferring a patient, align the bed frame with the bed and the two middle support plates with the patient's lower back. Then, push the two middle support plates into the patient's lower back, simultaneously connecting the air plug to the inflation seat. The airbag inflates, lifting the patient and reducing the pressure between the patient's body near the support plates and the bed. Then, the beam returns, and the transverse drive motor rotates, driving the two external blocks away from each other via a double-acting screw to the side of the next support plate. Then, push the support plate between the patient and the bed, and lift the patient again using the airbag. Repeating this movement will allow all the support plates to be inserted between the patient and the bed, lifting the patient. Because the load-bearing plate lifts the patient when the support plates are inserted, inserting multiple support plates sequentially reduces the friction between the support plates and the patient / bed, minimizing discomfort for the patient.

[0021] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0022] First implementation method:

[0023] Figure 1-7 This invention illustrates an accessible patient transfer structure, comprising an outer frame 1, a bed frame 2 fixedly connected to one end of the outer frame 1, multiple evenly distributed sliding grooves 3 on the top of the bed frame 2, a movable groove 301 on the lower side of the sliding grooves 3, a support plate 4 slidably connected inside the sliding grooves 3, the support plate 4 consisting of a load-bearing plate 401 and a movable plate 402, the movable plate 402 being fitted onto the outside of the load-bearing plate 401 and slidably connected thereto, an airbag 403 fixedly connected to one end of the load-bearing plate 401, an air plug 404 fixedly connected to one end of the movable plate 402, an air groove 405 inside the load-bearing plate 401, a through hole 406 communicating between the air groove 405 and the airbag 403, a transmission block 407 fixedly connected to one end of the movable plate 402, an air pump 6 fixedly connected to one end of the bed frame 2, and a connecting pipe 7 communicating between the air pump 6 and multiple inflatable seats 5.

[0024] A beam 11 is slidably connected between the side walls on both sides of the outer frame 1. A longitudinal drive motor 14 is fixedly connected to the outer wall of the outer frame 1. A lead screw 8 is fixedly connected to the output end of the longitudinal drive motor 14, and the lead screw 8 passes through the beam 11 and is threadedly connected to it. Hanging plates 1101 are fixedly connected to both ends of the beam 11. A bidirectional lead screw 13 is rotatably connected between the two hanging plates 1101, and a slide bar 9 is fixedly connected to it. Two external blocks 12 are provided between the slide bar 9 and the bidirectional lead screw 13. The external blocks 12 are threadedly connected to the bidirectional lead screw 13 and slidably connected to the slide bar 9. The two external blocks 12 are located at the positive and negative threads of the bidirectional lead screw 13, respectively. A transverse drive motor 10 is fixedly connected to the side wall of one of the hanging plates 1101. The output end of the transverse drive motor 10 is fixedly connected to one end of the bidirectional lead screw 13.

[0025] When transferring a patient, align the bed frame 2 with the bed, and align the two middle support plates 4 with the patient's waist. Then, the longitudinal drive motor 14 rotates, driving the two external blocks 12 towards the support plates 4 via the lead screw 8 and the beam 11. The external blocks 12 abut against the transmission block 407, pushing the two middle support plates 4 into the patient's waist. Simultaneously, the air plug 404 connects to the inflation seat 5, inflating the air bag 403. The air bag 403 expands, supporting the patient, and the pressure between the patient's body near the support plates 4 and the bed decreases. Then, the beam 11 returns to its original position. The horizontal drive motor 10 rotates, driving two external blocks 12 away from each other via the bidirectional lead screw 13, moving them to one side of the next support plate 4. The support plate 4 is then pushed between the patient and the bed, and the airbag 403 lifts the patient. Repeating this motion, all the support plates 4 can be inserted between the patient and the bed, lifting the patient. Because the load-bearing plate 401 lifts the patient when the support plate 4 is inserted, inserting multiple support plates 4 sequentially reduces the friction between the support plate 4 and the patient / bed, minimizing discomfort for the patient.

[0026] Second implementation method:

[0027] Figure 1 and Figure 4-6This invention illustrates a barrier-free patient transfer structure. Unlike the first embodiment, each of the two external blocks 12 has an electromagnet 1201 fixedly connected to one end, and the transmission block 407 is made of iron. With this configuration, when the patient is lowered, the electromagnet 1201 can be activated to attract the transmission block 407, pulling the multiple support plates 4 back sequentially. The load-bearing plate 401 has an inner misalignment hole 409 at one end inside the movable plate 402, and an outer misalignment hole 408 at one end of the movable plate 402. When the support plate 4 is pushed outwards, the outer misalignment hole... The outer misalignment hole 408 and the inner misalignment hole 409 are offset from each other, and the gas inside the air groove 405 cannot leak out. When the electromagnet 1201 pulls the transmission block 407 to separate the support plate 4 from the patient, the movable plate 402 moves to the left until the outer misalignment hole 408 and the inner misalignment hole 409 coincide. At this time, the gas inside the air bag 403 leaks out, which reduces the friction between the patient and the support plate 4, and the support plate 4 can be pulled out better. Through the above settings, the friction when the support plate 4 is separated from the patient can be reduced, and the comfort of the patient during transfer can be further improved.

[0028] An inner limiting block 410 is fixedly connected to the inner wall of the movable plate 402, and an outer limiting sleeve 411 is fixedly connected to one end of the movable plate 402. The outer limiting sleeve 411 is fitted onto the outside of the load-bearing plate 401, and an outer limiting block 412 is fixedly connected to one end of the load-bearing plate 401. The outer limiting block 412 is located inside the outer limiting sleeve 411. When the support plate 4 is inserted into the lower side of the patient, one end of the load-bearing plate 401 abuts against the inner limiting block 410. When the support plate 4 is pulled out, the outer limiting block 412 abuts against one end of the outer limiting sleeve 411. Through the above arrangement, the displacement between the load-bearing plate 401 and the movable plate 402 can be limited.

[0029] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this invention.
