[0002] Sick patients who are bedridden for a long time, especially those with severe illness, will be bedridden for a long time for infusion treatment. However, since most patients are often mentally unstable, agitated, and even have blurred consciousness, their arms will move subconsciously. The movement of the patient's upper limbs often causes the infusion tube to shift, resulting in complications such as bleeding and hematoma at the puncture site, affecting the patient's infusion treatment;

[0003] For example, a single-sided upper limb restraint device with a publication (announcement) number of CN212547323U comprises a front chest restraint belt, an upper arm restraint belt and a hand restraint sleeve; the front chest restraint belt is a rectangular structure, and two first bed-tie straps are arranged oppositely at the two ends of the top of the front chest restraint belt; the upper arm restraint belt has two identical structures and are arranged oppositely at the two ends in the length direction of the front chest restraint belt, and a second bed-tie strap is arranged on the upper arm restraint belt; the hand restraint sleeves have two identical structures, and a third bed-tie strap is arranged on the hand restraint sleeves; the two hand restraint sleeves are respectively connected to the two upper arm restraint belts by two connecting straps, and both connecting straps are length-adjustable structures;

At the same time, the restraints tied on the upper limbs will cause marks of varying degrees, making the use effect less than ideal. For this reason, we propose an upper limb restraint device.

[0036] From the above, we can know that:

[0037] The utility model aims at the following technical problems: in the process of using the existing technology, the patient's body and upper limbs are limited by multiple sets of restraints, which is cumbersome to operate when they need to be relaxed in the later stage. At the same time, the restraints tied on the upper limbs will cause different degrees of marks, making the use effect less than ideal; the technical solutions of the above embodiments are adopted. At the same time, the implementation process of the above technical solutions is:

[0038] When in use, first buckle the fixing frame 3 on the edge of the bed board, then rotate the threaded rod 4 so that the threaded rod 4 drives the transmission block 5 to move downward until the transmission block 5 is tightly attached to the bed board, then place the patient's upper limbs on the inner side of the lower transparent protective gear 1, cover the upper transparent protective gear 2, so that the upper transparent protective gear 2 drives the docking cavity 6 to correspond to the docking ear 7, and at this time the docking ear 7 is in the inner cavity 8;

[0039] Then, the T-shaped movable rod 14 is pulled upward, so that the T-shaped movable rod 14 drives the sliding block 15 to squeeze and contract the return spring 16, thereby moving the trapezoidal block 17 upward, and then pushing the pull cap 12 to make the anti-slip rod 11 move along the inner side of the mounting fixed tube 10. When the anti-slip opening 18 corresponds to the position of the trapezoidal block 17, the anti-slip rod 11 has been inserted into the docking cavity 6 and the inner side of the docking ear 7. The T-shaped movable rod 14 is released, and the elastic force generated by the return spring 16 pushes the sliding block 15 to move downward until the trapezoidal block 17 is inserted into the inner side of the anti-slip opening 18, forming a displacement limit for the anti-slip rod 11. When the upper transparent protective gear 2 needs to be opened in the later stage, the T-shaped movable rod 14 is pulled upward to release the limit on the anti-slip rod 11, and then the anti-slip rod 11 is pulled to separate from the docking cavity 6 and the docking ear 7, and finally the upper transparent protective gear 2 is opened.

[0040] Through the above configuration, the present application can certainly solve the above technical problems and achieve the following technical effects:

[0041] 1. The utility model adopts the structural design of the positioning mechanism and the carrying docking mechanism, so that the device can easily fix the lower transparent protective gear 1 on the bedside, and can quickly open and close the lower transparent protective gear 1 and the upper transparent protective gear 2, so as to fix the patient's upper limbs without causing strangulation marks on the patient's upper limbs. It can also be quickly disassembled and assembled in the later stage, thereby improving the efficiency of the device.

[0042] 2. The utility model uses the structural design of the locking mechanism to enable the device to limit the position of the anti-drop rod 11 to prevent the anti-drop rod 11 from being separated from the docking cavity 6 and the docking ear 7, which is beneficial to the connection stability between the lower transparent protective gear 1 and the upper transparent protective gear 2.
