Intelligent internal fistula bandage

Abstract

The invention discloses an intelligent internal fistula bandage. The intelligent internal fistula bandage comprises a bandage body, a pressure sensor, a blooding sensor, a controller and a touch screen, wherein the pressure sensor and the blooding sensor are arranged on a first surface and are connected with the controller electrically; the touch screen is arranged on a second surface and is connected with the controller electrically; the controller comprises a memory and a processor; an executable code is stored in the memory; and the executable code can complete the following steps through execution by the processor: obtaining the current pressure value of the patient through the touch screen, creating a pressure adjusting scheme for the patient according to the pressure value and displaying the pressure value in current hemostasis stage and the time remaining through the touch screen, and specifically, the pressure adjusting scheme includes a reference pressure value and time of duration for each hemostasis phase of the patient. According to the bandage, more accurate and more standard pressure adjustment is achieved; the pressure adjustment does not depend on the experience ofusers and the adjustment error is small.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an intelligent internal fistula bandage. Background technique [0002] Arteriovenous fistulas are autologous vascular access in maintenance hemodialysis patients. After the end of hemodialysis treatment, hemostasis should be achieved by compression to completely close the puncture site of the internal fistula. Some literatures pointed out that some patients had internal fistula occlusion caused by improper hemostasis due to internal fistula compression, excessive subcutaneous bleeding caused tension edema, and syncope caused by excessive blood loss in patients fell to severe and even caused death of patients. Therefore, effective compression and hemostasis measures are taken. has important clinical significance. [0003] The current compression hemostasis mainly uses bandage compression for hemostasis. During hemostasis, the bandage is fixed on the puncture site to achieve effect...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, the degree of tightness of the bandage and the interval of adjustment are judged by nurses based on clinical experience, which may lead to too loose or too tight compression at the fistula puncture site

In addition, due to the changes of the disease and the condition of the blood vessels of some patients, the tremor of the arteriovenous fistula is weak. If the compression force is too large and the time is too long, the blood flow of the arteriovenous fistula will be affected, and even the fistula will be caused. the occlusion
