Dynamic monitoring and compression fixation device for arteriovenous vessels

Abstract

The invention relates to a dynamic monitoring and compression fixation device for arteriovenous vessels, comprising a hemodialysis strap for binding up an internal fistula puncture point and an oozing sensor for detecting oozing quantity of the internal fistula puncture point, the oozing sensor is disposed in the hemodialysis strap, the hemodialysis strap is also provided with a timing alarm for timing an alarming uses, and the timing alarm is disposed on the hemodialysis strap and may be electrically connected with the oozing sensor; the timing alarm can time the binding of the hemodialysis strap, an oozing volume threshold of internal fistula puncture point is preset in the timing alarm, and the timing alarm outputs oozing alarm information if the oozing sensor detects that oozing volume of the internal fistula puncture point matches with the oozing volume threshold of internal fistula puncture point. The dynamic monitoring and compression fixation device for arteriovenous vessels is compact in structure and convenient to use, allows effectively quantitated time for using a bandage on internal fistula, can provide timely prevention for blood oozing of the internal fistula and prolong the service time of the internal fistula, can effectively prevent complications, and is safe and reliable.

Description

technical field [0001] The invention relates to a monitoring compression fixation device, in particular to a dynamic monitoring compression fixation device for arteriovenous blood vessels, which belongs to the technical field of arteriovenous fistula alarm. Background technique [0002] Arteriovenous fistula is a common vascular access for maintenance hemodialysis patients. It is safe, has sufficient blood flow (200-300ml / min), less chance of infection, long maintenance time (generally 4-5 years), does not affect daily life, and is easy to access. It is the best choice for patients with long-term dialysis. Arteriovenous fistula "life channel" for hemodialysis patients. [0003] Improper protection of the arteriovenous fistula will affect the dialysis effect and the service life of the vascular fistula. Complications such as bleeding, thrombus, infection, occlusion of the arteriovenous fistula, and false arteries will lead to the disuse of the arteriovenous fistula. This no...

AI Technical Summary

Problems solved by technology

Improper pressing, such as too light pressure or the position of the hemostasis point is not correct, can easily cause subcutaneous hematoma or external bleeding, and excessive pressing can easily damage blood vessels, and even cause internal fistula occlusion

There are often "three inaccuracies" in the home care of internal fistula after hemodialysis for hemodialysis patients: inaccurate pressing pressure (pressing too much can easily cause subcutaneous hematoma, pressing too hard can easily damage blood vessels, and even cause internal fistula to be occluded); the pressing position is not accurate (The position of the compression hemostasis point is not correct, resulting in vascular fistula bleeding or even external bleeding); the pressing time is inaccurate (the time to loosen the elastic bandage is too short to cause blood from the vascular fistula, and the time to loosen the elastic bandage is too long to cause occlusion of the internal fistula), It has brought troubles to hemodialysis patients and nephrology nurses; that is, too tight bandage compression can cause closed fistula, while bandage compression too loose can cause bleeding

[0007] Summary of literature on prevention of fistula bleeding: improvement of compression method and compression position, improvement of puncture method, use of drugs, use of hemostatic bandage, etc. are all ineffective

Regarding how to prevent bleeding, I have consulted relevant professional authorities, but there is no clear and specific method, most of them are just experience, and it is difficult to meet the needs of modern medical development
