Disposable blood perfusion device swinging device

Abstract

The invention discloses a disposable hemoperfusion device swinging device. The disposable hemoperfusion device swinging device comprises a base, a driving motor, an eccentric wheel, a positioning block and a hemoperfusion device clamping mechanism, wherein the driving motor is fixedly installed on the base; a rotating shaft is arranged at the output end of the upper end of the driving motor; and the eccentric wheel is arranged at the upper end of the rotating shaft. The driving motor, the eccentric wheel, the swing rod and the hemoperfusion device clamping mechanism are arranged and used in cooperation, the driving motor is started, the motor is started to drive the eccentric wheel to rotate, and the hemoperfusion device clamping mechanism located at one end of the swing rod swings up and down; by means of a first spring at the lower end of the hemoperfusion device clamping mechanism, the first spring drives the hemoperfusion device clamping mechanism to transversely swing while the hemoperfusion device clamping mechanism swings up and down, and the blood swinging effect in the hemoperfusion device can be effectively improved; and by arranging the variable-speed motor, the medical staff can adjust the variable-speed motor according to the required swinging speed so as to meet different swinging requirements.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a disposable hemoperfusion device swinging device. Background technique [0002] At present, a perfusion device is needed in the conventional hemoperfusion treatment process. The structure of the perfusion device tank body includes a tank body. There are flow ports on the top and bottom surfaces of the tank body, and there are holes for connecting with pipelines at the flow ports. The connection tube, the relationship between the blood flow rate inside the perfusion device and the adsorption effect of resin particles on blood toxins has become a difficult problem for clinical medical staff. The formation of thrombus reduces the occurrence of thrombus blocking the perfusion device, but because the blood stays in the tank for a short time, the toxins in the blood flow out of the perfusion device before fully contacting the resin particles in the tank, which reduces the ...

Problems solved by technology

Therefore, the clinical dosage of anticoagulants is usually conservative, which leads to a higher probability of perfusion device blockage during treatment.

[0004] And the common hemoperfusion device is not firmly fixed, because the common hemoperfusion device is generally fixed on the dialyzer by binding the cuff, so not only it is easy to make the blood tank loose and slip, there is a safety hazard, but also increases The workload of medical staff reduces work efficiency
