Technical Field

[0001] This utility model relates to the field of medical assistive devices, and in particular to a rehabilitation wheelchair for critically ill patients in the ICU. Background Technology

[0002] During the rehabilitation process of critically ill ICU patients, specialized equipment is needed to assist in completing rehabilitation activities such as walking training. At the same time, it is necessary to ensure the safety of movement and riding. As a key assistive tool, rehabilitation wheelchairs not only need to meet the daily mobility needs of patients, but also need to be adapted to the weakened physical condition of patients, provide convenient adjustment functions, and help patients gradually regain their mobility. This is of great significance for improving the efficiency and safety of rehabilitation for critically ill ICU patients.

[0003] In the existing technology, the walking training assistive mechanisms of rehabilitation wheelchairs used for critically ill patients in the ICU are mostly fixed structures or require manual disassembly and storage. The adjustment of the armrests often relies on complex tools to operate multiple fixed parts. When the auxiliary support parts are put back in place, they need to be adjusted manually one by one. Even after being put back in place, they may still not fit tightly to the main body of the wheelchair due to structural design problems, making it difficult to achieve efficient storage.

[0004] The existing technology has the following drawbacks: the existing walking training assistive mechanism on the wheelchair cannot be stored and takes up a lot of space. The ICU ward environment is usually narrow, and it is difficult to quickly store the assistive mechanism after it is deployed. When not in use, it will occupy a lot of passage or storage space, which not only affects the movement and placement of other medical equipment, but may also obstruct people's movement and reduce the utilization rate of ward space. Therefore, a rehabilitation wheelchair for ICU critically ill patients is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a rehabilitation wheelchair for ICU patients, aiming to solve the problem that the walking training assistive mechanism structure on some existing wheelchairs cannot be stored.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a rehabilitation wheelchair for ICU critically ill patients, comprising a mobile cart, wherein a left baffle and a right baffle are fixedly connected to the upper surface of the mobile cart respectively, a moving rod is slidably connected to the inner wall of the right baffle, an armrest is fixedly connected to the outer wall of the moving rod, an auxiliary rod is slidably connected to the inner wall of the moving rod, a ring is fixedly connected to the outer wall of the auxiliary rod, a limit mechanism is provided on the inner wall of the right baffle, and a movable component is provided on the inner wall of the left baffle;

[0007] The limiting mechanism includes a locking block, which is slidably connected to the inner wall of the right baffle, and a limiting rod is inserted into the top of the locking block.

[0008] As a further description of the above technical solution:

[0009] The movable component includes a rotating rod hinged to the inner wall of the left baffle. A movable rod is slidably connected to the inner wall of the rotating rod, and an insert block is slidably connected through the inner wall of the movable rod. Two sets of insert blocks are provided, and the two sets of insert blocks are elastically connected by a movable spring.

[0010] As a further description of the above technical solution:

[0011] The limiting rod is threaded onto the top of the right baffle.

[0012] As a further description of the above technical solution:

[0013] The locking block is engaged with the outer wall of the moving rod, and the locking block is engaged with the outer wall of the auxiliary rod.

[0014] As a further description of the above technical solution:

[0015] The ring is slidably connected to the inner wall of the moving rod.

[0016] As a further description of the above technical solution:

[0017] The insert block is inserted into the inner wall of the right baffle.

[0018] This utility model has the following beneficial effects:

[0019] 1. In this utility model, when the patient is undergoing walking training, the assistant can adjust and fix the height of the handrail through simple manual operation.

[0031] Reference Figure 1 , Figure 2 and Figure 6 The movable component includes a rotating rod 10, which is hinged to the inner wall of the left baffle 2. The rotating rod 10 can rotate around the hinge point, thereby changing the position and angle of the movable rod 11. The movable rod 11 is slidably connected to the inner wall of the rotating rod 10. The rotating rod 10 has a slot corresponding to the movable rod 11, allowing the movable rod 11 to move left and right. The inner wall of the movable rod 11 is slidably connected to an insert block 12, which has a slot corresponding to the insert block 12, allowing the insert block 12 to move up and down. There are two sets of insert blocks 12, which are elastically connected by a movable spring 13. When the two sets of insert blocks 12 approach each other, the movable spring 13 is compressed. When resetting, the elastic force of the movable spring 13 carries the two sets of insert blocks 12 back to their original positions. The insert block 12 is inserted into the inner wall of the right baffle 3, which has a slot corresponding to the insert block 12.

[0032] Reference Figures 3-5The limiting rod 8 is threaded to the top of the right baffle 3. The right baffle 3 has a thread that matches the limiting rod 8. The locking block 7 is locked onto the outer wall of the moving rod 4 and the outer wall of the auxiliary rod 6.

[0033] Working principle: When a patient needs to use a wheelchair for walking training, the assistive person can manually unscrew the limiting rod 8. When the limiting rod 8 separates from the slot on the locking block 7, the locking block 7 is manually moved to the right. When the locking block 7 separates from the slots on the moving rod 4 and the auxiliary rod 6, the auxiliary rod 6 is manually moved upward. The auxiliary rod 6 will move upward along with the ring 9. When the ring 9 moves to the upper end of the slot inside the moving rod 4, the second slot on the auxiliary rod 6 and the second slot on the moving rod 4 coincide. At the same time, the ring 9 will move the moving rod upward. 4. Move upwards. The moving rod 4 will move the armrest 5 upwards. When the armrest 5 moves to the designated height, the locking block 7 will coincide with the second slot on the moving rod 4 and the auxiliary rod 6. Manually move the locking block 7 to the left so that the locking block 7 engages with the slots on the auxiliary rod 6 and the moving rod 4, thus completing the engagement of the auxiliary rod 6 and the moving rod 4. Then, manually tighten the limiting rod 8 to limit the locking block 7. At this time, the assistive person can manually grip the auxiliary rod 6 to maintain the balance of the wheelchair, and the patient can hold the armrest 5 to perform walking training.

[0034] When it is necessary to retract the moving rod 4 and the auxiliary rod 6, manually unscrew the limiting rod 8. When the limiting rod 8 separates from the slot on the locking block 7, manually move the locking block 7 to the right. When the locking block 7 separates from the slot on the moving rod 4 and the auxiliary rod 6, the auxiliary rod 6 and the moving rod 4 will move back to their initial positions under their own gravity. The handrail 5 will also move back to its initial height. At this time, manually move the locking block 7 to the left so that the locking block 7 completes the limiting of the moving rod 4 and the auxiliary rod 6. Then tighten the limiting rod 8 to complete the limiting of the locking block 7.

[0035] When the patient needs to use a wheelchair, the assistive person can manually press the insert 12. The two sets of inserts 12 will move closer together and compress the movable spring 13. When the insert 12 separates from the slot on the right baffle 3, the assistive person can manually move the movable rod 11 to the left a certain distance, then manually flip the movable rod 11 outward to open it and release the insert 12. The two sets of inserts 12 will separate from each other under the elastic force of the movable spring 13. When the patient sits in the wheelchair, the assistive person can manually press the two sets of inserts 12 closer together, then move the movable rod 11 to the initial position, and then manually move the movable rod 11 to the right. When the insert 12 coincides with the slot on the right baffle 3, the assistive person can manually release the insert 12. The elastic force of the movable spring 13 will cause the two sets of inserts 12 to be inserted into the slot on the right baffle 3, thus limiting the movable rod 11 and the rotating rod 10. When the wheelchair is traveling on an inclined road, the rotating rod 10 and the movable rod 11 can shield the patient's body and prevent the patient from accidentally tilting to the side.
