Problems solved by technology

[0003] Hemodialysis is one of the commonly used dialysis methods in nephrology. However, the dialysis tubes used for hemodialysis in the prior art have the following deficiencies: the dialysis tubes often cannot be kept for a long time due to related infections and need to be replaced regularly, which increases the medical burden of patients and Complications related to reinsertion of tubes; secondly, the dialysis tube has

Embodiment 1

[0037] refer to Figure 1~4 : An anti-infection hemodialysis tube of the present embodiment, comprising a main body 5, a clamp switch 3, a sealing plug 13 and a heparin cap; the front end of the main body 5 is provided with a blood return port 7 communicating with the venous cavity 12, and the blood backflow The port 7 is used to reinfuse blood; the side wall of the main body 5 near the end of the blood return port 7 is provided with two blood drainage ports 6 connected to the arterial cavity 10, and the blood drainage port 6 is used to drain blood out of the body; the main body 5 The end of the end is provided with a vein end 4, an artery end 1 and a water injection end 2 connected to the water injection chamber 11; a sealing plug 13 is nested in the water injection end 2; a water bag 9 is provided at the end of the water injection chamber 11; The pipeline connecting the venous end 4 with the venous cavity 12 and the pipeline connecting the arterial end 1 with the arterial ca...

Embodiment 2

[0043] A method for using the anti-infection hemodialysis tube of this embodiment, using the anti-infection hemodialysis tube as described in Example 1, comprises the following steps:

[0044] 1) Pre-puncture work and guide wire implantation into blood vessels, the guide wire penetrates from the blood return port 7 into the transvenous cavity 12 and then passes through the vein end 4;

[0045] 2) After the anti-infection hemodialysis tube enters the blood vessel along the guide wire, observe the upper scale of the main tube body 5 to the corresponding position, take out the guide wire, and close the clamp switch 3;

[0046] 3) Fix the anti-infection hemodialysis tube, connect the arterial end 1 and the venous end 4 at the end of the main body 5 to the corresponding external instruments, and open the clamp switch 3;

[0047] 4) After hemodialysis, inject 5ml and 6ml of tube lock solution 15 from the arterial end 1 and venous end 4 of the anti-infection hemodialysis tube respect...

Embodiment 3

[0052] Compared with Example 2, the method for using the anti-infection hemodialysis tube of this embodiment has the following differences:

[0053] In step 4), the lock solution 15 is prepared by mixing 10 ml of hypertonic saline with a Nacl content of 10% (w / w) and 8 mg of heparin sodium.

[0054] In step 5), the dosage of the physiological saline 16 is 8ml.

Abstract

An anti-infection hemodialysis pipe comprises a main pipe body, clipping switches, a sealing plug and a heparin cap. A blood return port communicated with a venous cavity is formed in the front end of the main pipe body and used for conveying blood back; a plurality of blood drainage ports communicated with an arterial cavity are formed in the side wall, close to the blood return port end, of the main pipe body and used for draining blood out of a body; a venous end, an arterial end and a water injection end which is communicated with a water injection cavity are arranged at the tail end of the main pipe body; the sealing plug is embedded in the water injection end; a water bag is disposed at the tail end of the water injection cavity; the clipping switches are arranged on a pipeline communicated with the venous cavity and the arterial cavity and on a pipeline communicated with the arterial end and the arterial cavity respectively; the outer wall of the main pipe body, the inner wall of the venous cavity and the inner wall of the arterial cavity are coated with nano silver coatings. The anti-infection hemodialysis pipe is simple in structure, good antibacterial performance can be achieved through the nano silver coatings, the water bag sealing blood return port, the blood drainage ports and special tube-sealing fluid, and catheter associated infections are prevented, so that indwelling time of the hemodialysis pipe in a body of a patient is prolonged, and medical burdens on the patient and nursing workloads of medical staff are reduced.

Description

technical field [0001] The invention relates to a medical device, in particular to an anti-infection hemodialysis tube and a use method thereof. Background technique [0002] The kidney is a part of the urinary system, responsible for filtering impurities in the blood, maintaining the balance of body fluids and electrolytes, and finally producing urine that is excreted through the subsequent pipeline; it also has endocrine functions to regulate blood pressure: usually patients with renal failure or necrosis Hemodialysis or peritoneal dialysis treatment is required to replace the function of the kidneys to filter impurities in the blood and maintain the balance of body fluids and electrolytes. [0003] Hemodialysis is one of the commonly used dialysis methods in nephrology. However, the dialysis tubes used for hemodialysis in the prior art have the following deficiencies: the dialysis tubes often cannot be kept for a long time due to related infections and need to be replaced...
