Description

Dispensing device

Technical Field

The invention relates to the technical field of medical instruments, in particular to a medicine dispenser.

Background

The dispensing in the medical treatment refers to transferring a drug solution or a drug powder into a liquid bag for intravenous infusion, and a conventional dispensing method is generally performed using a syringe. The general operation method is to extract the liquid medicine from a plurality of injection bottles by using a syringe and then inject the liquid medicine into an infusion bottle for infusion. In the case of powder for injection, it must be dissolved by infusion. The above operation process is complicated, the labor intensity for nurses is high, and the liquid medicine is easily contaminated in the process of repeatedly sucking the liquid medicine by the syringe.

To this end, the grant publication No. CN 201821954431.1 discloses a needle device for dispensing and filtering, which solves the technical problems of complicated operation and low working efficiency in the dispensing and injecting process of the existing needle, and comprises a puncture needle and a connection base, wherein the upper part of the connection base is provided with an inward-concave connection groove, and the connection groove is separated into an upper first groove chamber and a lower second groove chamber which are not communicated with each other by an elastic sealing membrane; the inner parts of the first puncture end part and the second puncture end part are both double channels, the channel B is communicated with the channel D, and the channel A and the channel C both penetrate through the bottom end of the needle seat and are not communicated with each other; a one-way sealing membrane is arranged between the filtering part and the puncture needle in the first groove chamber, the middle of the one-way sealing membrane is an upward convex one-way sealing membrane boss, and a closed gap is formed in the middle of the one-way sealing membrane boss.

However, the needle device for filtering the dispensed medicine has the following defects, which are mainly reflected in that:

1. the needle device adopts a needle double-pipeline structure, and the requirement of the structure is supposed to be met. The diameter of a needle head is increased, and the daily liquid preparation and the medicine preparation are both in a small bottle shape, so that the daily medicine preparation cannot be carried out, and the inconvenience in use is caused; if a common needle tube diameter is adopted, the production process for realizing the needle tube structure in the prior art is difficult, cannot be realized or has extremely high production cost, and cannot be used as a disposable medical instrument;

2. the needle head device needs to be combined and matched with a needle seat, a single sealing membrane, an upper support, a lower support and a filtering membrane, so that the second through hole and the third through hole are communicated with the channel C in a sealing way through a gap in the middle of the convex part of the one-way sealing membrane; the fourth through hole and the fifth through hole are communicated with the channel A in a closed mode through the filtering membrane, and for disposable medical products, the structure is complex, the combination is complex, the matching precision requirement is high, the disposable medical products cannot be used once deviation or displacement occurs, the cost is high, and the assembly difficulty is high;

3. when dispensing, the channel B is communicated with the channel D and cannot be closed, so that no matter how the injection bottle (such as a powder injection bottle) is extracted, residues are generated, the injection bottle cannot be completely injected into the injection bottle, waste is caused, and the accuracy of medicine allocation is influenced;

4. the puncture needle that this dispensing device used is special construction, and is unable to buckle, so difficult injection bottle (like the powder injection bottle), the infusion bottle that will connect keep the level simultaneously and place, and injection bottle, infusion bottle probably one of them is in the level and another is in the tilt state, and puncture needle length is limited simultaneously and can't remove, and is inconvenient dispenses.
