Medicine extracting and injecting mechanical arm

Abstract

The invention discloses a medicine extracting and injecting mechanical arm. The medicine extracting and injecting mechanical arm comprises an injector plunger push-pull device and an injector body clamping device. The injector body clamping device is used for clamping a cylinder of an injector and driving a syringe needle of the injector to prick into and pull out of a bottle body. The injector plunger push-pull device comprises a rack, a stepping motor, a coupler, a sliding sleeve support, a lead screw, a sliding rail, a lead screw nut, a sliding block, a magnetic grid sensor, a lead screw support, a direct current motor, a gearbox, a left clamping body, a right clamping body, a plunger push rod, a sliding block base, a pressure sensor and a sliding rod. The gearbox comprises a worm shaft frame, a worm shaft, a worm wheel, a worm wheel support, an inner gear, planet gears and a gear shaft. By means of the structure, in the aspect of intelligent preparing of the vein transfusion medicine, work of medicine extracting and injecting is achieved. The direct contact between people and the medicine can be reduced, and losses are reduced.

Description

technical field [0001] The invention relates to the field of medical mechanical equipment, in particular to a drug extraction and injection manipulator in an intravenous infusion drug preparation device. Background technique [0002] At present, domestic hospitals use the method of dispensing ampoule drug bottles and powder bottles: hold a syringe in one hand and a large solution bottle in the other hand, and use the syringe to extract the solvent for diluting the powder drug; inject the solvent in the syringe into the powder drug bottle, and inject the dissolved drug or injection. A bottle of suction syringe, the method of adding the medicine sucked into the syringe into the solution bottle to complete the work of preparing intravenous infusion medicine. This method of operation can easily cause the operator's hands to directly contact the liquid medicine, causing pollutants to enter the liquid, resulting in liquid contamination.

AI Technical Summary

Problems solved by technology

This method of operation can easily cause the operator's hands to directly contact with the liquid medicine, causing pollutants to enter the liquid, resulting in liquid contamination.

[0003] Some toxic drugs, especially chemotherapeutic drugs, are cytotoxic drugs, which cause harm to relevant staff through three ways: respiratory inhalation, dietary intake and skin contact. In actual work, the preparation of radiopharmaceuticals, nurses have been using manual Operation, the process of preparation and distribution of such drug configurations will cause great harm to the staff. The toxicity of the drug can lead to the destruction of normal cells, which can damage normal DNA and cause reproductive toxicity; it can cause cancer; if the staff will affect during pregnancy fetal development leading to teratogenicity
