[0020] Example 1

[0021] The temporary hemodialysis catheter protection device described in this embodiment is as follows: Figures 1 to 4 As shown, it includes a vertically arranged fixing block 2, and elastic bands 1 are fixed to both ends of the fixing block 2. The right end of the left elastic band 1 is fixed to the left wall of the fixing block 2, and the left end of the right elastic band 1 is fixed to the right wall of the fixing block 2. The ends of the two elastic bands 1 are fixed by Velcro. When in use, the two elastic bands 1 are wrapped around the patient's thighs, and the fixing block 2 is fixed to the patient's thighs by Velcro. The elastic bands 1 can also be tightened on the patient's thighs by tying a knot;

[0022] The fixing block 2 is provided with a through groove communicating with each other from top to bottom, and the temporary hemodialysis tube is installed in the through groove;

[0023] Two clamping plates 4 are vertically arranged in the through groove, and grooves 3 are opened on the left and right groove walls of the through groove. There are two grooves 3, the left groove 3 is opened on the left groove wall of the through groove, and the right groove 3 is opened on the right groove wall of the through groove; a first spring 5 is arranged between the groove bottom of the groove 3 and the corresponding clamping plate 4, and there are two first springs 5, the left end of the left first spring 5 is fixed on the groove bottom of the left groove 3, and the right end is fixed on the left side wall of the left clamping plate 4, the left end of the right first spring 5 is fixed on the right side wall of the right clamping plate 4, and the right end is fixed on the groove bottom of the right groove 3; in the natural state of the first spring 5, the temporary tube is clamped between the two clamping plates 4, and the two clamping plates 4 are continuously pushed toward the middle of the through groove by the first spring 5. After the tube passes through the through slot, the temporary tube is clamped between the two clamping plates 4; this paragraph of text as a whole constitutes a fixing assembly for fixing the temporary tube in the through slot. When the fixing assembly is in use, when the temporary tube passes through the through slot, the two clamping plates 4 are pushed into the groove 3, and the first spring 5 is compressed. When the temporary tube passes through the through slot, the first spring 5 pushes the two clamping plates 4 to clamp the side wall of the temporary tube, and fixes the temporary tube between the two clamping plates 4; of course, the fixing assembly can also install a telescopic rod 6 between the clamping plate 4 and the bottom of the groove 3, one end of the telescopic rod 6 is fixed to the bottom of the groove 3, and the other end is fixed to the side wall of the clamping plate 4, and the movement of the clamping plate 4 is limited by the telescopic rod 6 so that it can only move horizontally left and right, thereby ensuring the fixing effect of the temporary tube;

[0024] A protective shell 7 is detachably installed at the lower end of the fixed block 2. The fixing assembly fixes the temporary hemodialysis tube in the fixed block 2. The end of the temporary tube is located below the fixed block 2. The protective shell 7 is fixed to the lower end of the fixed block 2, and the end of the temporary tube is wrapped in the protective shell 7 to prevent the temporary tube from being pulled by clothes or when the patient is active. At the same time, it can also prevent dust and other impurities from contaminating the temporary tube, thereby improving the protection effect of the temporary tube.

[0025] When this embodiment is used, the end of the temporary tube is passed through the through slot, and the temporary tube is fixed in the fixing block 2 by the fixing assembly. The fixing block 2 is fixed to the patient's thigh by two elastic bands 1. The end of the temporary tube is located below the fixing block 2. The end of the temporary tube is installed in a protective shell 7, and the protective shell 7 is installed at the lower end of the fixing block 2 to prevent the temporary tube from being pulled by clothes or when the patient is active. At the same time, it can also prevent dust and other impurities from contaminating the temporary tube, thereby improving the protection effect of the temporary tube.

[0026] Example 2

[0027] This embodiment further illustrates the technology. Figure 1 and Figure 3 As shown, a plug plate 14 is vertically fixed to the upper end of the protective shell 7, and a limiting groove 17 for inserting the plug plate 14 is provided at the lower end of the fixing block 2, and the limiting groove 17 is provided at the lower end of the fixing block 2;

[0028] The wall of the limiting groove 17 is horizontally provided with a slide groove 13 communicating with the inside and outside. Figure 3 As shown, the left groove wall of the limiting groove 17 is provided with a slide groove 13 communicating with the inside and outside.

[0029] A fixing plate 9 is fixed in the chute 13, and the fixing plate 9 is fixed at the left end exit of the chute 13;

[0030] The fixing plate 9 is provided with through holes communicating with each other on the left and right sides, and a slide bar 11 is independently installed in the through hole, and the slide bar 11 slides along the hole depth direction of the through hole;

[0031] One end of the slide rod 11 passes through the slide slot 13 and is fixed with a baffle 10, and the other end passes through the limit slot 17 and is fixed with a clamping block 16. Figure 3 As shown, the left end of the slide rod 11 passes through the slide slot 13 and is vertically fixed with a baffle 10, and the right end passes through the slide slot 13 and is fixed with a clamping block 16;

[0032] The plug board 14 is provided with a card slot 15 for inserting the card block 16. The card block 16 is inserted into the card slot 15 to lock the plug board 14 in the limit groove 17, thereby fixing the protective shell 7 at the lower end of the fixed block 2;

[0033] A second spring 12 is installed between the block 16 and the fixing plate 9. Figure 3 As shown, the left end of the second spring 12 is fixed to the right side wall of the fixing plate 9, and the right end is fixed to the clamping block 16;

[0034] When the second spring 12 is in a natural state, the block 16 is inserted into the slot 15 , and the second spring 12 pushes the block 16 into the slot 15 , locking the plug plate 14 in the limiting slot 17 .

[0035] When the present embodiment is in use, the baffle plate 10 is pulled outward, the second spring 12 is forced to contract, the block 16 is pulled back into the slide groove 13, and the plug plate 14 is inserted into the limiting groove 17. When the slot 15 is aligned with the slide groove 13, the baffle plate 10 is released, the second spring 12 loses the force and recovers its deformation, pushing the block 16 into the slot 15, locking the plug plate 14 in the limiting groove 17, and installing the protective shell 7. When disassembly is required, the baffle plate 10 is pulled outward, and the block 16 is disengaged from the slot 15 under the drive of the slide rod 11, releasing the limit on the plug plate 14, and removing the protective shell 7 from the lower end of the fixed block 2, thereby realizing quick installation and disassembly of the protective shell 7.

[0036] like Figure 3 As shown, the right end of the block 16 is wedge-shaped with the upper end of the plug plate 14, and the lower right corner of the block 16 is beveled. When the plug plate 14 is inserted into the limit groove 17, the upper end of the plug plate 14 squeezes the inclined side wall of the block 16 and pushes the block 16 into the slide groove 13, saving an operation step of pulling the baffle 10 and speeding up the installation of the protective shell 7.

[0037] Example 3

[0038] This embodiment further illustrates the technology. Figure 1 As shown, the upper and lower ends of the clamp plate 4 are both inclined. When the temporary tube is inserted into the through groove, the closing of the temporary tube squeezes the inclined side wall of the clamp plate 4 and pushes the clamp plate 4 into the groove 3, which is beneficial to the fixation of the temporary tube.

[0039] Example 4

[0040] This embodiment further illustrates the technology. Figure 2 As shown, a connecting rope 8 is fixed to the front side of the fixed block 2, and the movable end of the connecting rope 8 is fixed to the protective shell 7. The upper end of the connecting rope 8 is fixed to the front side wall of the fixed block 2, and the lower end is fixed to the front side wall of the protective shell 7. When the patient undergoes hemodialysis, the protective shell 7 needs to be removed from the lower end of the fixed block 2 and connected to the protective shell 7 via the connecting rope 8 to prevent the protective shell 7 from being lost or falling, thereby avoiding unnecessary economic losses.

[0041] Example 5

[0042] This embodiment further illustrates the technology. The protective shell 7 is made of a transparent material. The protective shell 7 is preferably made of a transparent plastic material. Transparent plastic is cheap and widely available. Medical staff can check the status of the temporary catheter through the protective shell 7 and replace the damaged temporary catheter in time, which is beneficial to protecting the patient.
