[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Reference Figure 1 and Figure 2 The utility model provides an embodiment: an upper limb protection device for preventing accidental tube removal in patients with indwelling tubes, comprising a fixed lower ring 1, which is semi-arc-shaped and has a certain flexibility. The outer wall of the fixed lower ring 1 is provided with ventilation holes to increase the comfort of the user. The rear side of the fixed lower ring 1 is hinged with a fixed upper ring 2, which is used to fix the patient's arm. At the same time, the outer wall of the fixed upper ring 2 is also provided with ventilation holes, and the front end of the fixed lower ring 1 is fixedly connected with a fixed block 3.

[0033] Reference Figure 1 , Figure 2 and Figure 4The inner wall of the fixed block 3 is provided with a limiting component, which includes a pressing block 42, the outer wall of the pressing block 42 is slidably connected to the inner wall of the fixed block 3, and the left side of the rear end of the pressing block 42 is elastically connected to the fixed block 3 by a compression spring 43. The pressing block 42 and the clamping block 44 are squeezed to the front side by the elastic force of the compression spring 43, so that the clamping block 44 can slide into the inner wall of the limiting groove opened on the outer wall of the clamping strip 41, and the clamping strip 41 is limited, thereby limiting the fixed upper ring 2 and fixing and protecting the patient's upper limb. The right side of the rear end of the pressing block 42 is fixedly connected with a clamping block 44, and the outer wall of the clamping block 44 slides on the inner wall of the fixed block 3. The front end of the fixed upper ring 2 is hinged with a clamping strip 41, and the outer wall of the clamping strip 41 is provided with a plurality of groups of limiting grooves, which can limit the upper limbs of patients with different thicknesses. The clamping strip 41 is set to be made of nylon, and the clamping strip 41 can have a certain softness, which is convenient for medical staff to use.

[0034] Reference Figure 1 and Figure 3 A stretching assembly is provided at the bottom end of the fixed lower ring 1, and the stretching assembly includes an extension rod 5. The top right side of the extension rod 5 is hinged at the bottom end of the fixed lower ring 1, and the outer wall of the left end of the extension rod 5 is slidably connected to a storage rod 6. The extension rod 5 slides on the inner wall of the storage rod 6, so that the distance between the two groups of limiting assemblies can be changed, and can be retracted or adjusted according to the length of the patient's upper limbs, so that the limiting assemblies can be accurately fixed on upper limbs of different lengths, which increases flexibility and practicality. A bolt 7 is threadedly connected to the right side of the front end of the storage rod 6, and a fixing groove 8 is provided at the front end of the extension rod 5. The outer wall of the bolt 7 rotates on the inner wall of the fixing groove 8. There are multiple groups of fixing grooves 8, and the length of the extension rod 5 and the storage rod 6 can be quickly changed by the bolt 7, which increases convenience.

[0035] Reference Figure 1 There are two groups of limiting components, which are respectively arranged on the upper right side of the extension rod 5 and the upper left side of the storage rod 6. The limiting component on the upper right side of the extension rod 5 is used to limit the patient's wrist, and the limiting component on the upper left side of the storage rod 6 is used to limit the patient's elbow, so that the patient's upper limbs cannot move, thereby increasing the fixed protection effect. There are two groups of fixing components, which are respectively arranged on the lower right side of the extension rod 5 and the lower left side of the storage rod 6. The device is limited by the two groups of fixing components, which increases stability.

[0036] Reference Figure 4 and Figure 5A fixing assembly is provided at the bottom right end of the extension rod 5, and the fixing assembly includes a mounting block 91. The top of the mounting block 91 is fixedly connected to the bottom end of the extension rod 5 for providing support. A limiting strip 92 is fixedly connected to the rear side of the mounting block 91. A plurality of limiting grooves are provided inside the limiting strip 92. The limiting strip 92 is made of nylon. The limiting strip 92 has a certain flexibility, so that the limiting strip 92 can fit with the railing on the bed when in use to increase stability. A limiting block 93 is slidably connected to the inner wall of the front end of the mounting block 91. The limiting block 93 is elastically connected to the mounting block 91 through a reset spring 94. The elastic force of spring 94 squeezes the limiting block 93 and the pull rod 95 toward the front side, so that the limiting block 93 slides into the inner wall of the limiting groove on the limiting strip 92. The front side of the limiting block 93 is set to be inclined from top to bottom, so that the limiting strip 92 can be pulled upward on the inner wall of the mounting block 91 to reduce the length of the limiting strip 92. The device as a whole will not loosen unless the limitation on the limiting strip 92 is released. Pull rods 95 are fixedly connected to the left and right ends of the limiting block 93. The outer wall of the pull rod 95 is slidably connected to the inner wall of the mounting block 91. The limiting block 93 is driven to move by the pull rod 95, so that the limitation on the limiting strip 92 can be released and the device can be removed from the bed.

[0037] Working principle: During use, when the patient's upper limb needs to be protected and fixed, first rotate the bolt 7 down according to the patient's arm length to release the restriction on the extension rod 5, and pull the extension rod 5 out from the inner wall of the storage rod 6. When the device length is suitable, rotate the bolt 7 into the corresponding inner wall of the fixing groove 8 to restrict the extension rod 5.

[0038] At this time, place the patient's wrist on the right fixed lower ring 1, and then place the patient's elbow on the left fixed lower ring 1, and then press the pressing block 42 to squeeze the compression spring 43, drive the clamping block 44 to move backward, and insert the clamping strip 41 from the upper end of the fixed block 3, so that the clamping strip 41 drives the fixed upper ring 2 to limit the patient's upper limbs. When the fixed upper ring 2 fits the patient's arm, release the pressing block 42 to allow the clamping block 44 to slide into the inner wall of the limiting groove on the clamping strip 41, limit the clamping strip 41, and thus limit the fixed upper ring 2.

[0039] Then, the limiting strip 92 is passed through the railing of the hospital bed, and the movable end of the limiting strip 92 is inserted through the bottom end of the mounting block 91, so that the limiting strip 92 drives the limiting block 93 to slide on the inner wall of the mounting block 91, thereby squeezing the reset spring 94, and the limiting block 93 is pushed into the inner wall of the limiting groove opened on the limiting strip 92 by the elastic force of the reset spring 94, thereby limiting the length of the limiting strip 92.

[0040] By limiting at the wrist and above the elbow, the device can effectively fix the patient's upper limbs. By pulling the pull rod 95 backward, the limiting block 93 can be driven to move to squeeze the return spring 94, so that the limiting block 93 slides out from the inner wall of the limiting groove on the limiting strip 92, thereby canceling the limitation on the limiting strip 92.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
