Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example
[0025] Please see Figure 1-4 This utility model provides a technical solution: a transfer stretcher with full-body restraint, including a plate 1. A groove 11 is provided on one side of the plate 1, and a telescopic plate 2 is slidably connected inside the groove 11. Multiple slots 12 are provided on the top surface of the plate 1, and multiple mounting blocks 3 and multiple second locking blocks 31 are respectively inserted into the slots 12. Straps 32 are mounted on the top surface of the mounting blocks 3. A first locking block 15 is fixedly mounted in the middle of the top surface of the plate 1. The ends of the straps 32 are engaged with the second locking block 31 or the first locking block 15 via locking components. During adjustment, the telescopic plate 2 is pulled outwards to extend... The retractable plate 2 moves within the slide groove 11, allowing medical staff to adjust the length of the stretcher according to the user's height. Medical staff can flexibly add or remove the installation block 3 and the second locking block 31 according to the patient's condition to adapt to different patients' conditions. After installing the installation block 3 and the second locking block 31, insert one end of the locking member of the strap 32 into the corresponding second locking block 31 or first locking block 15. The second locking block 31 and the first locking block 15 have locking grooves corresponding to the locking members. The second locking block 31 or the first locking block 15, in conjunction with the strap 32, can restrain the patient onto the stretcher. Example
[0026] Please see Figure 1-4 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. Multiple insertion holes 21 are provided on both sides of the telescopic plate 2. Sliding rods 41 are slidably provided on both sides of the plate body 1. The sliding rods 41 are inserted into any corresponding insertion hole 21. A second support rod 22 is fixedly connected to one side of the telescopic plate 2. When it is necessary to move the telescopic plate 2, the sliding rods 41 are pulled outward. After the sliding rods 41 are away from the insertion holes 21, the telescopic plate 2 can be moved normally. Medical staff hold the second support rod 22 and pull the telescopic plate 2 outward.
[0027] The plate 1 has cylindrical grooves 4 on both sides. A circular ring plate 42 is slidably connected inside the cylindrical groove 4. The circular ring plate 42 is fixedly sleeved on the outer circumference of the sliding rod 41. A first spring 43 is provided inside the cylindrical groove 4. The two ends of the first spring 43 are fixedly connected to the side wall of the circular ring plate 42 and the side wall of the cylindrical groove 4, respectively. The first spring 43 is movably sleeved on the outer circumference of the sliding rod 41. When the sliding rod 41 is moved, the sliding rod 41 drives the circular ring plate 42 to move. The movement of the circular ring plate 42 and its cooperation with the cylindrical groove 4 compress the first spring 43. When the sliding rod 41 enters the cylindrical groove 4, the telescopic plate 2 moves normally. When it reaches the appropriate position, the sliding rod 41 is released. The first spring 43 uses its elasticity to restore the circular ring plate 42 to its original position. The circular ring plate 42 drives the sliding rod 41 to insert into the corresponding insertion hole 21, completing the adjustment of the telescopic plate 2.
[0028] The slot 12 is slidably connected to the two sides of the slot 12 with the snap-fit plate 53. The second snap-fit block 31 has a snap-fit groove 33 on both sides. The snap-fit plate 53 is inserted into the corresponding snap-fit groove 33. When installing the mounting block 3, the mounting block 3 is inserted into the slot 12. The downward pressure of the mounting block 3 causes the snap-fit plate 53 to be squeezed to both sides. When the snap-fit groove 33 moves to the position of the snap-fit plate 53, the snap-fit plate 53 is inserted into the snap-fit groove 33 to complete the snap-fit.
[0029] Square grooves 5 are provided on both sides of the bottom of multiple slots 12. The square grooves 5 are opened on the bottom surface of the plate body 1. A sliding plate 52 is slidably connected inside the square groove 5. The side wall of the sliding plate 52 is fixedly connected to the end of the snap-fit plate 53. A second spring 51 is fixedly connected to the side wall of the sliding plate 52. The end of the second spring 51 is fixedly connected to the side wall of the square groove 5. When the mounting block 3 needs to be removed, the sliding plate 52 is moved. The sliding plate 52 moves in the square groove 5. The movement of the sliding plate 52 drives the snap-fit plate 53 to move. The cooperation between the sliding plate 52 and the square groove 5 compresses the second spring 51. When the snap-fit plate 53 moves away from the snap-fit groove 33, the mounting block 3 can be removed.
[0030] A first support rod 14 is fixedly connected to the side of the plate 1 away from the slide groove 11, and support frames 13 are fixedly connected to the four corners of the bottom surface of the plate 1; the support frames 13 help support the plate 1, and the first support rod 14 makes it convenient for the user to grip.
[0031] In use, medical staff can adjust the length of the stretcher according to the user's height. During adjustment, the sliding rod 41 is pulled outwards, causing the circular plate 42 to move. The movement of the circular plate 42, in conjunction with the cylindrical groove 4, compresses the first spring 43. When the sliding rod 41 moves away from the insertion hole 21, the telescopic plate 2 can move normally. Medical staff then use the second support rod 22 to pull the telescopic plate 2 outwards. The telescopic plate 2 moves within the sliding groove 11. After reaching the appropriate position, the sliding rod 41 is released, and the first spring 43 utilizes its elasticity... The force restores the circular piece 42 to its original position. The circular piece 42 drives the sliding rod 41 to insert into the corresponding second support rod 22, completing the adjustment of the telescopic plate 2. Medical staff install the mounting block 3 according to the patient's condition. When it is necessary to restrain the patient's legs, the mounting block 3 is inserted into the slots 12 on both sides of the first locking block 15. After the mounting block 3 is inserted into the slots 12, it presses the locking plate 53 to both sides. The locking plate 53 drives the sliding plate 52 to move in the square groove 5. The cooperation between the sliding plate 52 and the square groove 5 compresses the second spring 51. When the locking plate 52 is engaged, the second spring 51 is compressed. After the slot 33 moves to the position of the snap-fit plate 53, the second spring 51 uses its elasticity to restore the sliding plate 52 to its original position, and the snap-fit plate 53 is inserted into the slot 33, completing the fixation of the mounting block 3. The length of the strap 32 can be adjusted, which is a conventional technique in the prior art and will not be described in detail here. After adjusting the strap 32 to a suitable length, insert one end of the snap-fit part of the strap 32 into the corresponding second snap-fit block 31 or first snap-fit block 15. The second snap-fit block 31 and the first snap-fit block 15 have snap-fit slots corresponding to the snap-fit parts. The first locking block 15, in conjunction with the strap 32, can restrain the patient onto the stretcher. One medical staff member holds the first support rod 14, while another holds the second support rod 22 to lift the stretcher away. In this utility model, medical staff can adjust the length of the telescopic plate 2 according to the patient's height, avoiding inconvenience caused by the stretcher being too short or too long. Furthermore, the modular design of the mounting block 3, the second locking block 31, and the strap 32 allows medical staff to flexibly add or remove components according to the patient's condition, adapting to different patients' conditions and increasing the stretcher's applicability.
