Abstract

The invention relates to a device for adjusting the conveying flow of medicine liquid. The device comprises a shell, a rotary shaft, a plurality of cams, extruding blocks, a liquid inlet tube and a liquid outlet tube. The rotary shaft is rotationally arranged in the shell, the cams are coaxially and fixedly arranged on the rotary shaft, and the liquid inlet tube and the liquid outlet tube are arranged in the shell and communicated through a plurality of connecting tubes. Elastic tube segments made of elastic materials are arranged on the connecting tubes, the elastic tube segments of the connecting tubes are correspondingly arranged below the cams, and the extruding blocks are arranged between the elastic tube segments of the connecting tubes and the cams. The cams are rotated through the rotary shaft, the cams push the extruding blocks to vertically move, and then adjustment on closing, opening and flow of the connecting tubes is achieved. According to the technical scheme, the device has the advantages that the structure is simple, the inner diameter of flow limiting tube segments of the connecting tubes is only 0.05 mm to 0.07 mm, and the flow of the medicine liquid can be precisely adjusted by adjusting the number of the elastic tube segments, closed or opened by rotating the rotary shaft, of the connecting tubes.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a device for regulating the delivery flow of medical liquid. Background technique [0002] At present, the flow rate of non-electrically driven infusion pumps on the market cannot be adjusted manually, and the flow rate or flow rate is fixed, which cannot be adjusted appropriately according to the individual conditions of the patient; while the flow regulator on the ordinary infusion pipeline is a manual pressure wheel type, and the flow rate is usually It is manually adjusted according to the experience of medical staff, and the flow rate is also visually measured according to the speed of dripping, which is very imprecise. Contents of the invention [0003] (1) Technical problems to be solved [0004] The technical problem to be solved by the present invention is to provide a device for adjusting the delivery flow rate of the liquid medicine. The device is provided with seve...
