Liquid medicine conveying control device

Abstract

The invention discloses a liquid medicine conveying control device which comprises a conveying body, a flowing channel in the conveying body comprises a liquid inlet hole and a liquid outlet hole at both ends of the conveying body, the outlet end of the liquid inlet hole is communicated with a small port of a first conical hole, a large port of the first conical hole is communicated with a buffer hole, the diameter of the buffer hole is greater than the diameter of the large port of the first conical hole and the liquid outlet hole, the liquid inlet hole, the liquid outlet hole, the first conical hole and the buffer hole are coaxial, the liquid medicine conveying control device also comprises a second conical hole, the second conical hole and the first conical hole are mirror-symmetric in relative to the middle cross section of the buffer hole, three brackets are fixed on the step of the buffer hole, a circular ring is arranged at the focal point of the three brackets, a cylindrical spring which is in a compression state and connected with a filter plug is fixed on the circular ring, the large end surface of the first conical hole is fixedly provided with a rubber light push rod arranged along the axial direction of the first conical hole, and the end of the a rubber light push rod is connected with a conical rubber stopper. The liquid medicine conveying control device has the advantages of simple, compacted and artful structure design, and has the automatic on-off function of filtration and liquid medicine delivery .

Description

technical field [0001] The invention belongs to the technical field of liquid medicine delivery, and in particular relates to a liquid medicine delivery control mechanism. Background technique [0002] In medical treatment, it is usually necessary to mash some drugs and then extract their juice or grind them to take a certain concentration of mixed solution for use, but the concentration of the drug solution is required to be within a certain range or the drug residue must be filtered out, and a certain concentration can be achieved when necessary. Automatic on-off control under the concentration of liquid medicine, the current corresponding equipment is complicated and costly, and it is not suitable for large-scale promotion and use. However, medical devices usually require the smaller the better, and the simpler the structure, the more practical. Contents of the invention [0003] The purpose of the present invention is to solve the above technical problems and provide a...
