[0031] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.

[0032] Example:

[0033] like Figure 1 , 2 As shown in FIG. 3 , the utility model provides a limb fixation device for dialysis, comprising two sets of hinged fixing units, the fixing units comprising two sets of shells 101, the two sets of shells 101 are interlocked to form an installation space, a plurality of installation plates 201 are arranged in the installation space, a positioning plate 102 is arranged in the shell 101, and the installation plate 201 is slidably clamped between the shell 101 and the positioning plate 102.

[0034] The shell 101 is fixed in the dialysis area, and the patient can place his arm on the shell 101. Protective pads 301 are provided on two groups of shells 101 to improve comfort during use. Multiple groups of mounting plates 201 can slide between the shell 101 and the positioning plate 102.

[0035] like Figure 2 , 3As shown in FIG. 4 , in this embodiment, a movable plate 202 is slidably penetrated on the mounting plate 201, one end of the movable plate 202 penetrates outside the housing 101, a slide groove 107 is provided on the housing 101, and the movable plate 202 is slidably clamped in the slide groove 107. A strap 206 is provided at one end of the movable plate 202, wherein a fixing strap 108 is provided at the bottom of the two groups of housings 101, and Velcro 207 is provided at the ends of the strap 206 and the fixing strap 108.

[0036] The housing 101 can be fixed in the use area by the fixing belt 108, and its position can be fixed by the Velcro 207. The movable plate 202 can be driven to slide in the slide groove 107 by the sliding mounting plate 201, so as to adjust the position of the strap 206. After adjustment, the end of the strap 206 can be fixed by the Velcro 207, so as to effectively fix the patient's arm and prevent interference with the installation position of the dialysis tube.

[0037] like Figure 2 , 3 As shown, in this embodiment, a fixing assembly is provided on the movable plate 202, and the movable plate 202 is fixed in position by the fixing assembly during the sliding process. The fixing assembly includes a baffle 203 provided at one end of the movable plate 202 located in the installation space, a fixing column 204 is provided on the baffle 203, a plurality of fixing holes 103 are provided on the housing 101 at intervals along the direction of the slide groove 107, the fixing column 204 can be inserted into the fixing hole 103, and an elastic member 205 is provided between the baffle 203 and the positioning plate 102.

[0038] When not fixed, the fixing column 204 is not stuck in the fixing hole 103 under the action of the elastic member 205, so that the movable plate 202 can slide in the slide groove 107 to adjust the position of the strap 206. After adjustment, the strap 206 is pulled and the end of the strap 206 is fixed by the Velcro 207. In the process of pulling the strap 206, the movable plate 202 is driven to slide in the mounting plate 201, thereby driving the baffle 203 to move, so that the fixing column 204 is stuck in the fixing hole 103, and the position of the strap 206 is fixed, so as to prevent the position of the strap 206 from moving during the subsequent dialysis process and causing the dialysis tube to fall off.

An installation gap 105 is provided between the limiting plate 104 and the shell 101 in one group of shells, and a stop block 106 is provided in the other group of shells 101. When the two groups of shells 101 are engaged, the stop block 106 is stuck in the installation gap 105.

[0040] A limit plate 104 is provided to limit the range of movement of the baffle 203 to prevent the baffle 203 from moving too far and causing the movable plate 202 to separate from the mounting plate 201. An installation gap 105 is provided to facilitate the installation of the baffle 203, the mounting plate 201 and the movable plate 202. The stop block 106 is used to block the installation gap 105 when the two sets of shells 101 are closed, thereby improving the convenience of assembling the device.

[0041] Specific usage and beneficial effects of the utility model:

[0042] When the device is in use, it is fixed on the dialysis bed by the cooperation of the fixing belt 108 and the Velcro 207. The patient can place his arms on the two sets of shells 101 and fix the patient's arms by pulling the straps 206 to prevent the patient's arms from moving during the dialysis process and causing interference with the dialysis. The position of the straps 206 can be adjusted by sliding the mounting plate 201 in the shell 101. After adjustment, the movable plate 202 is driven to slide in the mounting plate 201 during the process of pulling the straps 206. The movable plate 202 drives the baffle 203 to move during the sliding process, so that the fixing column 204 is clamped in the corresponding fixing hole 103, so that the position of the straps 206 is adjusted and fixed to adapt to the use of different patients and effectively prevent interference with the installation position of the dialysis tube.
