Automatic medicine dispenser capable of measurement

Abstract

The invention discloses a meterable automatic dispensing device, which belongs to the technical field of medical instruments. It solves the problems of lack of measuring tools, difficult control, unguaranteed working accuracy and cumbersome operation process in the dispensing process. The meterable automatic dispensing device includes a dual-purpose pump for blowing and sucking, a ventilation tube and a catheter. A switching valve for blowing and sucking is connected in series between the dual-purpose pump and the ventilation tube. Both the blowing port and the suction port of the pump are connected to the blowing-suction switching valve. The metering automatic dispensing device also includes a cylindrical and vertically placed measuring cylinder. The upper interface and the lower interface are connected, the other end of the ventilation tube is connected to the upper interface of the measuring cylinder, one end of the catheter is connected to the lower interface of the measuring cylinder, and the other end of the catheter is connected to a Dispensing needles. The metering automatic dispensing device not only has accurate metering, is safe and reliable, and is convenient to operate, but also has the characteristics of simple structure and low cost.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an apparatus for infusion and medicine dispensing. Background technique [0002] When dispensing medicine for intravenous infusion in a hospital, the usual method of operation is to first use a syringe to extract a small amount of liquid from the infusion bottle and inject it into one or more powder injection bottles, and then draw it out and inject it into the infusion bottle after the medicine dissolves, so as to be configured as a liquid for infusion. liquid medicine. The above-mentioned operation process is more complicated and labor-intensive. [0003] For this reason, someone has designed a kind of medical dispensing device (application number: 200420007724.0), comprises fixed frame, adorns solvent rack at one end of fixed frame, and vacuum pump is housed at the other end, also has connecting conduit, and the two ends of connecting conduit all are equipped with...
