Description

Medical three-way joint

Technical Field

The utility model belongs to the technical field of medical instrument, concretely relates to medical three way connection.

Background

The infusion pump is a liquid medicine infusion apparatus commonly used in clinic, and generally injects one or more mixed medicines into a liquid storage device through a medicine injection tee joint, and then adds other commonly used liquids such as normal saline, glucose and the like for dilution, and then infuses into a patient. The capacity of the injector used in the existing hospital is usually not more than 50ml, the injector needs to be drawn out from a container filled with liquid medicine when medicine is injected into an infusion pump, and then the medicine is added into a liquid storage device through an infusion pump medicine injection tee joint.

A Chinese utility model patent with the patent number ZL201520565130.X discloses a medical three-way joint; the three-way pipe comprises a three-way pipe body, a three-way cock for controlling the communication of any two or three pipelines, and further comprises an internal thread connecting sleeve, a limiting baffle ring, a rubber pad sleeve and a rubber pad cap. The rubber cap is provided with an annular opening, a first pipeline of the three-way pipe body is connected with the internal thread connecting sleeve, a pipe orifice of the first pipeline extends to the outer end of a connecting port of the internal thread connecting sleeve, an external thread is arranged on a second pipeline of the three-way pipe body, the limiting baffle ring is arranged on the second pipeline, the end part of a third pipeline of the three-way pipe body is connected with the rubber cushion sleeve, the rubber cushion cap covers the rubber cushion sleeve, and the rubber cushion is compressed and fixed in the rubber cushion sleeve. The device has the defects that one end of the product is connected with a medicine injection tee joint on a pipeline of an infusion pump, the product is connected and fixed with the medicine injection tee joint through an internal thread connecting sleeve in a screwing way, the other two ends of the product are respectively connected with an injector and a container containing medicine to be injected, when the medicine is injected into a liquid storage device through continuous suction action, a three-way cock is required to be continuously rotated to open the corresponding pipeline, and the operation process is complex.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome prior art's the aforesaid not enough, provide a medical three way connection, this medical three way connection can with annotate the medicine tee bend effective connection, carry out liquid infusion, washing work.

In order to achieve the above purpose, the utility model provides a following technical scheme:

the utility model provides a medical three way connection, includes tee bend body, internal thread adapter sleeve, and the first pipeline and the internal thread adapter sleeve of tee bend body are connected to the mouth of pipe of first pipeline extends to the connector outer end of internal thread adapter sleeve, is provided with the external screw thread on the second pipeline of tee bend body, the third pipeline, its characterized in that second pipeline inner chamber is equipped with the inward check valve.

The medical three-way joint is characterized in that the end parts of the second pipeline and the third pipeline are screwed with sterile protective caps.

The utility model has the advantages that:

1. the structure is simple, and the use is convenient;

2. the sterility of the infused medicine is enhanced;

3. the workload of medical staff is reduced.

Detailed Description

As shown in fig. 1-3, a medical three-way joint comprises a three-way pipe body 1 and an internal thread connecting sleeve 2, wherein a first pipeline 3 of the three-way pipe body 1 is connected with the internal thread connecting sleeve 2, a pipe orifice of the first pipeline 1 extends to the outer end of a connecting port of the internal thread connecting sleeve 1, and external threads 6 are arranged on a second pipeline 4 and a third pipeline 5 of the three-way pipe body 1, and the medical three-way joint is characterized in that an inward check valve 7 is arranged in an inner cavity of the second pipeline 4, and an aseptic protective cap 8 is screwed at the end parts of the second pipeline 4 and the third pipeline 5.

When specifically using, with 1 tip of first pipeline and infusion pump pipeline on injection tee bend connection, rotation internal thread adapter sleeve 2 makes the utility model discloses with injection tee bend fixed connection, screw off aseptic protective cap 8, 4 end connection splendid attire of second pipeline to check valve 7 in being equipped with have the container that needs to pour into liquid into, 5 tip of third pipeline are connected with the syringe, because the injection tee bend that first pipeline 3 is connected has inside one-way circulation function, need pour into liquid into when twitching the syringe through in can only getting into the syringe to check valve 7, then second pipeline 4 is the encapsulated situation when promoting the syringe, liquid can only get into the stock solution device through first pipeline 3 in, twitch the syringe through continuous, promote, need not pull out the syringe and accomplish the operation of injecting the stock solution device with the liquid medicine.

Above is the utility model discloses a preferred embodiment, all rely on the utility model discloses the change that technical scheme made, produced functional action does not surpass the utility model discloses during technical scheme's scope, all belong to the utility model discloses a protection.

Claims (2)

1. The utility model provides a medical three way connection, includes tee bend body, female connection cover, and the first pipeline and the female connection cover of tee bend body are connected to the mouth of pipe of first pipeline extends to the connector outer end of female connection cover, is provided with the external screw thread on the second pipeline of tee bend body, the third pipeline, its characterized in that: and an inward check valve is arranged in the inner cavity of the second pipeline.

2. The medical three-way joint according to claim 1, wherein: the end parts of the second pipeline and the third pipeline are screwed with sterile protective caps.
