Problems solved by technology

[0002] The devices used in clinical dispensing methods include disposable dispensing syringes and disposable dispensing devices. The operation method of disposable dispensing syringes is that the operator first inserts the disposable dispensing syringe into the infusion bottle to suck a small amount of liquid, then pulls it out and then inserts it into the injection bottle. Inject the liquid into the infusion, and after the medicine powder dissolves, it is drawn back into the disposable dispensing syringe, and finally the disposable dispensing syringe is inserted into the infusion bottle to inject the medicine liquid, and then pulled out; the operation method of the disposable dispensing device is that the operator puts the disposable Insert the needles at both ends of the dispenser into the injection bottle and the soft infusion bottle respectively, place the soft infusion bottle upside down on the top of the injection bottle, squeeze the soft infusion bottle to make the liquid in the soft infusion bottle flow into the injection bottle, and wait for the injection After the medicine powder in the bottle is dissolved, invert the injection medicine bottle on the top of the soft infusion bottle, and then squeeze the soft infusion bottle to make the liquid medicine flow into the squeeze soft infusion bottle; the process of using a disposable dispensing syringe is cumbersome, easy to infection, and insoluble particles cannot be filtered , the scope of application of the disposable dispenser is narrow, it can only be used for soft infusion bottles, and the circulation speed of the liquid medicine is slow

Abstract

The inventio discloses an injection medicine moving filter based on external force. The filter comprises an inserting needle 1, an inserting needle 2, a liquid channel, a gas channel 1, a gas channel2 and an injection medicine moving filter body based on the external force. The filter is provided with the liquid channels and the two independent gas channels which do not communicate with each other; by changing gas pressures and gas flow directions in the gas channels, a pressure difference in an infusion bottle and a medicine bottle is changed, and the output direction and the output amount of liquid between the infusion bottle and the medicine bottle are achieved; and the filter has the advantages that the operation is easy and convenient, the pollution is reduced, the medicine dispensing time is short, the application range is wide, the filter can be used for hard infusion bottles (glass bottles) not limited to soft infusion bottles, and insoluble micro-particles are effectively reduced and filtered.

Description

technical field [0001] The invention relates to the technical field of medical appliances, in particular to a filter for injecting medicine through external force. Background technique [0002] The devices used in clinical dispensing methods include disposable dispensing syringes and disposable dispensing devices.
