Abstract

The invention provides a liquid transmission control device and a liquid transmission system. The device comprises a pipeline bearing member, a flow rate sensor, an adjustment structure and a controller. The pipeline bearing member is designed to allow pipelines made from soft materials and used for liquid transfer to be arranged therein, the pipeline bearing member includes an accommodating space, and the accommodating space is used for accommodating at least one part of the pipelines; the flow rate sensor is used for detecting the flow rate of liquid transmission in the pipelines; the adjustment structure is used for adjusting the cross-sectional areas of the pipelines arranged in the accommodating space so as to adjust the flow rate of liquid transmission in the pipelines; the controller is used for outputting a control signal to the adjustment structure according to the flow rate detected by the flow rate sensor, so that the adjustment structure adjusts the cross-sectional areas ofthe pipelines arranged in the accommodating space. The device can monitor the condition of in-vitro and in-vivo liquid transmission and control the liquid transmission speed timely to avoid medical accidents caused by abnormal flow rates.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a liquid transmission control device and a liquid transmission system. Background technique [0002] The transmission of blood or liquid medicine between the body and the outside of the body is very common in current medical treatment. It is necessary to inject medicinal liquid into the human body. [0003] At present, when the above-mentioned liquid transmission is performed in the existing technology, it is usually directly connected to the pipeline, and the status of the body fluid transmission cannot be monitored, which may cause a risk of medical accidents. For example, in the current conventional blood drawing / donating process, the blood flows out of the human body mainly through the pressure difference between the human body's blood pressure and the vacuum negative pressure in the blood collection bag. On the one hand, this conventional solution cannot automatic...
