Real-time monitoring cell return liquid uniform shaking device

Abstract

The invention relates to a real-time monitoring cell return liquid uniform shaking device, and belongs to the field of medical instruments. The device comprises a placement box for fixedly accommodating a cell return bag, a shaking system, a monitoring control system and a rack; the shaking system comprises a motor and a crank and rocker mechanism; the crank and rocker mechanism comprises a crank,a rocker, a fixed supporting rod and a connecting rod; a transmission shaft of the crank is rotationally arranged on the rack and is fixedly connected with a rotating shaft of the motor, and the tailend of a rotating part of the crank is rotationally connected with the lower end of the connecting rod; the lower end of the fixed supporting rod is fixed to the rack; one end of the rocker is rotationally connected with the upper end of the fixed supporting rod, and the other end of the rocker is rotationally connected with the upper end of the connecting rod; the placement box is fixed to the rocker; the monitoring control system monitors the state of the cell return bag, and controls the shaking system to be started or stopped. Cell return liquid can be efficiently and automatically shakenuniformly, the shaking action is stopped after uniform shaking, manpower is saved, manual work negligence is avoided, and the cell return safety is improved.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a real-time monitoring cell reinfusion liquid shaking device. Background technique [0002] Cell therapy technology refers to the transplantation or infusion of normal or bioengineered human cells into the patient's body. The newly injected cells can replace and repair damaged cells or stimulate and regulate the immune system, with stronger immune killing function, so as to achieve the treatment of diseases the goal of. In general, cell therapy includes two categories: immune cell therapy and stem cell therapy. Immune cell therapy includes targeted dendritic cell therapy technology (T-DC technology), CIK cell therapy technology, NK cell therapy technology, etc.; stem cell therapy is used in the treatment of cancer, viral diseases, blood diseases, cardiovascular diseases, diabetes, elderly Dementia, beauty, anti-aging and health care have shown increasing application value.

AI Technical Summary

Problems solved by technology

[0003] Cell reinfusion is an important part of cell therapy technology. At present, cell reinfusion bags are mostly used for cell reinfusion. However, due to the biological characteristics of cells, the cells in the reinfusion suspension tend to form agglomerates or stick to the inner wall of the cell reinfusion bag. At least, the cells in the cell reinfusion bag cannot be completely returned to the patient, resulting in waste of cells, and at worst, medical accidents due to blockage of blood vessels by cell clusters

Under the current medical conditions, in the process of cell reinfusion, medical staff frequently shake the cell solution, which is labor-intensive and prone to medical accidents due to negligence.

In the prior art, the method of suspension high-frequency oscillation and horizontal reciprocating shaking is also used to shake the cell reinfusion solution, but these methods do not overcome the cell sedimentation caused by the gravity of the cells during the shaking process, so there will be cell cluster formation
