Embodiment Construction

[0085] A preferred embodiment of the present invention will be described in detail below in conjunction with the drawings.

[0086] see figure 2 , is a structural diagram of the portable vascular access status monitoring device according to the first embodiment of the present invention.

[0087] The portable vascular access status monitoring device (hereinafter referred to as the monitoring device) 2 of this embodiment mainly includes a measuring device 20 and a monitoring module 220 . The measuring device 20 includes a vibration sensing module 200 and a communication module 202 .

[0088] The vibration sensing module 200 (such as one or more three-axis accelerometers (Accelerometer), force sensors or other types of vibration sensors). It is used to sense the blood flow-induced vibration of a specific part of the subject's vascular access (such as artery, vein, arteriovenous autologous fistula or arteriovenous artificial blood vessel), and generate vibration data correspond...

Abstract

The invention discloses a portable vascular access state monitoring device, which includes a measuring device and a monitoring module. The measurement device senses blood flow-induced vibration data at the site of the vascular access of the subject through the vibration sensing module, and transmits the sensed data externally through the communication module. The monitoring module controls the electronic device to receive the data and determines the vibration evaluation index corresponding to the state of the part according to the received sensing data. The portable vascular access state monitoring device of the present invention has the advantages of small size, portability, low cost, etc., and is suitable for home vascular access state monitoring.

Description

technical field [0001] The present invention is related to the state monitoring of blood vessel access, in particular to a portable blood vessel access state monitoring device. Background technique [0002] Patients with renal function loss or insufficiency must rely on vascular access to send blood to a hemodialysis machine outside the body for blood purification to filter waste from the blood. The aforementioned vascular access can be surgically created and used to transport the patient's blood to the hemodialysis machine and return the dialyzed blood to the patient. [0003] Generally speaking, there are mainly two kinds of vascular accesses produced by surgery: Arteriovenous Fistula (AVF) and Arteriovenous Graft (AVG). [0004] see Figure 1A , is a schematic diagram of an arteriovenous artificial vessel. The arteriovenous artificial blood vessel 14 can be an artificial plastic tube, with one end connected to the artery 12 and the other end connected to the vein 10 . ...
