Embodiment Construction

[0023] The hemoperfusion device of the present invention will be further described below in conjunction with the accompanying drawings: Figure 1-13 As shown: Assemble a hemoperfusion device of the present invention, the structure and function are as follows:

[0024] Such as figure 1 As shown: according to the circulation path diagram of the hemoperfusion device, a hemoperfusion device of the present invention is made, the venous pressure sensor 3, the pipeline blocker 4, the venous circulation line 5, and the perfusion device 6 are hemoperfusion devices of the prior art, The present invention mainly arranges the arterial pressure sensor 1 on the arterial circulation pipeline 8, and sets the post-pump pressure sensor 2 behind the blood pump 7, and designs a control device connected with the arterial pressure sensor 1 and the post-pump pressure sensor 2. By detecting the arterial pressure , venous pressure and their difference are compared with the standard value, there is an...

Abstract

A blood perfusion device for the external circulation of blood is composed of blood perfusion unit and controller consisting of detecting circuit, data processing unit, man-machine interactive unit, executing unit and pump driver unit. An artery pressure detector is arranged on the artery circulation loop of blood perfusion unit. Its functions include measuring the pressures of artery and vein andthe temp of blood, sound-light alarm, data display, automatic heating, etc.

Description

technical field [0001] The invention relates to a blood perfusion device, which belongs to the field of medical equipment, and specifically belongs to the medical equipment for extracorporeal circulation of blood. Background technique [0002] Use activated carbon or resin as the hemoperfusion device as the adsorbent. When doing hemoperfusion, you are most worried about the hemoperfusion device coagulation. The harbinger of coagulation is an increase in the pressure behind the pump. The pressure difference between the inlet and outlet of the hemoperfusion device should be accurately detected to determine whether the pressure difference exceeds the normal value. When a venous line ruptures or opens, which can cause unexpected blood loss, venous pressure should be checked. Sometimes arterial pressure may be too low due to arterial indwelling needle blockage, arterial duct bending, and selected patients with thinner blood vessels. If the blood pump will still work with a large...
