Embodiment 1

[0032] Such as Figure 1-2 As shown, the buckle-type dialysis tubing fixation device for arm internal fistula includes two clamping components, one clamping component is used to clamp the dialysis tube connected with the venipuncture needle 4, and the other clamping component is used to clamp the dialysis tube connected with the arterial needle 4. The dialysis tubing 6 connected with the puncture needle 5, each clamping assembly includes a first clamping block 1 and a second clamping block 2, the first clamping block 1 and the second clamping block 2 are detachably connected, and the first clamping block 1 and the second clamping block 2 are detachably connected. The clamp block 1 is provided with a first clamp groove 11 matched with the dialysis tubing 6, the second clamp block 2 is provided with a second clamp groove 21 matched with the first clamp groove 11, the first clamp block 1 and When the second clamping block 2 is connected, the first clamping groove 11 and the secon...

Embodiment 2

[0037] Such as Figure 1-3 As shown, the structure of the buckle-type dialysis tubing fixing device for internal fistula in the arm of this embodiment is the same as that of Embodiment 1, the difference is that it also includes a protective cover 7 that matches the shape of the arm, and the clamping assembly and the protective cover 7 is detachably connected, the protective cover 7 extends at least to the center of the palm along the puncture site of internal fistula in the arm, the side of the protective cover 7 near the palm is provided with a limit hole 72 for cooperating with the thumb, and the protective cover 7 is made of cloth Made of quality materials.

[0038] The buckle-type dialysis tubing fixation device for internal fistula in the arm of this embodiment, by setting the protective cover 7 of cloth material, on the one hand, reduces the arm of the patient exposed to the air and reduces the temperature of the patient's arm through the heat-retaining properties of the...

Embodiment 3

[0041] Such as Figure 1-3 As shown, the structure of the buckle-type dialysis tubing fixing device for internal fistula in the arm of this embodiment is the same as that of Embodiment 1, the difference is that it also includes a limiting strip 8 for fixing the clamping assembly on the arm. The position bar 8 is made of cloth material, and the second clamping block 2 is provided with a through hole 23 for passing through the limit bar 8 .

[0042] The buckle-type dialysis tubing fixing device for internal fistula in the arm of this embodiment is used to fix the clamping component to the arm by setting the limit bar 8, so that the position between the clamping component and the arm is fixed, thereby preventing the patient’s arm from moving The displacement of dialysis tubing 6, meanwhile, through hole 23 is set on the second clamping block 2 and is used for passing through the limiting bar 8, makes the connection between the limiting bar 8 and the second clamping block 2 easier...

Abstract

The invention relates to the field of medical instruments, in particular to a snap-fit fixture for an arm internal fistula dialysis tube fixture, comprising a protective hood matched with the arm in shape and at least two clamping components; each clamping component includes a first clamp block and a second clamp block which are releasably connected; the first clamp block is provided with a firstclamp groove matched with the dialytic tube; the second clamp block is provided with a second clamp groove matched with the first clamp groove; after the first clamp and the second clamp block are connected and the first clamp channel and the second clamp channel are fastened, a clamping passage to clamp a dialytic tube is formed, the clamping passage is in length width direction of an arm; the second clamp block is releasably connected with the protective cover; as the clamping channel involves long length of the dialytic tube clamped, the dialytic tube of great length is fixed to the arm, the dialytic tube is not easily disconnected with the arm, no deformation rarely occurs, and smooth flowing of blood in the blood dialysis is guaranteed.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a buckle-type dialysis tube fixing device for fistula in the arm. Background technique [0002] Hemodialysis is the process of draining blood from the body to the outside, removing metabolic waste and excess water in the blood through a dialysis machine, and then returning the purified blood to the body. It is one of the renal replacement therapy methods for patients with acute and chronic renal failure. 1. At present, arteriovenous fistula is usually performed in the arm through surgery for hemodialysis. The artery near the wrist and the adjacent vein are sutured to form an autologous arteriovenous fistula or an artificial blood vessel is placed in the arm to connect adjacent veins. Arteriovenous fistula is formed. During hemodialysis, the arterial needle and venous needle connected to the dialysis machine through the dialysis tube are used to puncture the internal fistula to ...
