Description

Protective sleeve for arteriovenous fistula

technical field

The utility model belongs to medical auxiliary products, in particular to a protective cover for arteriovenous fistula.

Background technique

For patients undergoing hemodialysis in the department of nephrology, arteriovenous fistula in the arm is required. After the internal fistula is completed, hemodialysis treatment will be punctured from this part. After the fistula operation, the fistula site should be prevented from being compressed, especially within two weeks after the operation, so as to avoid a sudden drop in blood flow and cause the internal fistula to be occluded. To prevent long-term compression of the internal fistula, there are many patients in the clinic, it is difficult to persist, they will unconsciously compress the fistula, especially some elderly patients, and those who like to sleep on their side and do not change their positions, it is easy to oppress the internal fistula. Fistula leads to occlusion of the internal fistula, shortens the service life of the internal fistula and fails to make buckles.

Many hemodialysis patients need to undergo dialysis frequently. During this process, the internal fistula needs to be punctured to draw out the blood. How to effectively protect the blood vessels and prolong the service life of the internal fistula is also a matter of great concern to hemodialysis patients and doctors.

In addition, after ostomy, local heat preservation is needed, especially in winter, which is conducive to the survival of the fistula. At present, most patients generally adopt the method of wrapping quilts or towels for internal fistula care. In order to maintain a suitable temperature, it is necessary to constantly change the towel , the operation is cumbersome and brings great burden to patients.

How to design a protective sleeve for arteriovenous fistula, which can protect the hand tube of arteriovenous fistula, which is easy to install, fixed firmly, prevents the oppression of the stoma site, and relieves the pain of the patient; It is beneficial to the survival of the fistula, and how to make the patient care for the fistula site conveniently during the dialysis treatment stage, so as to prolong the service life of the internal fistula. These are all technical problems to be solved urgently at present.

Further, the antibacterial layer includes a cuprous oxide layer or cuprous oxide nanoparticles.

Further, the adjustment belt is provided with a female button and a female button and three sub-buttons respectively. The three sub-buttons divide the adjustment belt into three levels, which can be determined according to the thickness of the patient's arm. You need to buckle the sub-button for that gear.

Further, the support frame is a plastic frame whose size and shape are the same as those of the observation window, and is mainly used to isolate the cotton core to prevent the cotton core from being too soft and easy to deform. When wrapped around the arm, It will touch the stoma.

Further, the housing is provided with a battery installation port and a sound transmission hole for the horn, and the battery installation port is provided with a cover plate.

Further, the power switch is installed on the shell.

(3) Beneficial effects

Compared with the prior art, the arteriovenous fistula protective sleeve proposed by the utility model has the following beneficial effects: the combination of the load-bearing sensor and the alarm controller in the utility model can send out an alarm when the ostomy site is compressed. The alarm reminds the patient to remove the pressure, prevents the stoma from being oppressed, and relieves the pain of the patient; the design of the buckle makes the protective cover easy to install and fix firmly; the design of the adjustment belt allows different patients to adjust according to their needs, preventing the protection The cover is too tight or too loose; at the same time, the design of the cotton core can ensure the heat preservation of the fistula, which is conducive to the survival of the fistula; the design of the antibacterial layer can reduce the growth of bacteria and increase the use time of the protective cover. The number of cleanings is reduced, which not only reduces the workload of medical staff, but also increases the service life of the protective cover.
