Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an arteriovenous fistula monitor for hemodialysis patients. Background Art

[0002] Arteriovenous fistula is mainly used for maintenance hemodialysis treatment of patients with renal failure. The specific operation is to anastomose the patient's artery near the wrist or elbow and the adjacent vein to arterialize the anastomosed vein. The formed arteriovenous fistula is convenient for repeated puncture and can provide sufficient blood flow for hemodialysis treatment several times a week.

[0003] Arteriovenous fistula stenosis and thrombosis are the most common complications after arteriovenous fistula repair. Some high-risk patients have poor vascular conditions and are likely to have fistula occlusion within a period of time after fistula construction or repair. If the repair is not timely, the patient may lose precious vascular resources and have to endure the pain of repeated surgery. Therefore, it is necessary to monitor the blood flow velocity at the arteriovenous fistula of patients with renal failure and maintenance hemodialysis, especially high-risk patients, on a daily basis. If the blood flow is too slow, it indicates that there is a risk of blockage at the arteriovenous fistula, and measures must be taken to dilate the blood vessels or eliminate the thrombus to restore its smooth flow.

[0004] According to the survey results of existing technologies, the existing dedicated medical equipment is bulky, which limits the promotion of monitoring technology; the emerging wearable blood flow monitoring technology has not been widely recognized due to defects such as low test accuracy and fatigue limit.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The utility model is provided with a measuring instrument at the lower end of the main body, which detects the blood flow of the arteriovenous fistula and then transmits the measurement result to the processor chip. The processor chip processes the data and sends it to the screen to display the measurement result and to the speaker to broadcast the measurement data.

[0015] 2. The utility model has the characteristics of small size and easy to carry, and can directly obtain the results of measurement data.

[0016] 3. Users can obtain arteriovenous fistula blood flow information in a timely manner through screen display and speaker broadcast, which solves the problem that it is difficult for patients to accurately judge the condition of the fistula independently, avoids treatment delays caused by untimely discovery of reduced fistula flow, and significantly reduces the risk of fistula blockage in hemodialysis patients.
