Description

Disposable dedicated dispensing device with double needle and one-way valve

technical field

The utility model relates to a disposable special dispensing device with double needles and a one-way valve.

Background technique

The dispensing device currently used clinically is mainly a disposable syringe of more than 20 ml. The disadvantage is that the syringe is only equipped with a needle, which causes the needle to be inserted repeatedly at the rubber stopper of the medicine bottle and the infusion bottle. The hygienic conditions are up to standard, but the rubber stopper is unavoidably damaged due to repeated use of the needle to penetrate the rubber stopper, which will cause the damaged rubber particles of the rubber stopper to be injected into the infusion bottle along with the drug, which will cause "foreign matter" in the infusion bottle , Intuitively, it will cause the patient's psychological uneasiness, and in some cases, it will also cause secondary pollution and cause adverse infusion reactions such as fever.

Contents of the invention

The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a disposable special dispensing device with double needles and a one-way valve. The technical solution adopted by the utility model to solve the technical problem is: avoid multiple Repeatedly interspersed with rubber plugs is the main point to overcome the deficiencies of the prior art. The structure of the utility model includes a liquid suction pipe, a first one-way valve, a protective cap A, a liquid injection pipe, a second one-way valve, a protective cap B, and a pipe joint. It is characterized in that the suction pipe, the liquid injection pipe, and the pipe joint are connected by a three-way connection, the inner chambers of the liquid suction pipe, the liquid injection pipe, and the pipe joint are connected to each other, and the liquid suction pipe and the liquid injection pipe are connected to the pipe joint at the same time. The inner diameter of the outer port of the connector is consistent with the existing syringe needle handle connector, and is used to connect the syringe used for dispensing medicine. A first one-way valve is arranged in the suction pipe, and the liquid flow control direction of the first one-way valve is from outside to inside , there is a second one-way valve in the liquid injection pipe, the liquid flow control direction of the second one-way valve is from inside to outside, the outer layer of the liquid suction pipe is also provided with a protective cap A, and the outer layer of the liquid injection pipe is also provided with a protective cap Cap B, all parts of the utility model can be made of polymer plastic materials, and the ends of the liquid suction pipe and the liquid injection pipe are arranged as needle-point shapes, which replace the needles to absorb and inject the liquid medicine.

Method of use: the pipe joint of the utility model can be used by connecting the syringe. When in use, the suction tube is inserted into the liquid medicine in the vial or ampoule, and at the same time, the liquid injection tube is inserted into the large infusion bottle, and the needle plug of the syringe is pulled, and the liquid medicine is sucked back through. The first one-way valve of the suction pipe enters the syringe, and the second one-way valve of the liquid injection pipe is in a closed state at this time, and the needle plug is pushed here, and the medicinal liquid is injected into the large infusion bottle from the second one-way valve of the liquid injection pipe. At this moment, the first one-way valve of the liquid suction pipe is closed, and the utility model is put into the medical waste recovery box for harmless treatment after completing the dispensing.

The beneficial effect of the utility model is that the utility model has a reasonable structure, is safe and convenient to use, and avoids secondary pollution in the dispensing process.
