Description

Y-connector

technical field

The utility model relates to a medical device, in particular to a Y-shaped connector.

Background technique

Intervention therapy is an emerging treatment method between surgery and internal medicine. It is to make tiny channels with a diameter of several millimeters on blood vessels and skin under the guidance of imaging medicine (X-ray, ultrasound, CT, MRI) or through the original human body. It is a method of inserting a special catheter or instrument into the lesion for diagnostic imaging, treatment or tissue collection. Percutaneous coronary angioplasty (PCTA) is a percutaneous arterial balloon dilatation catheter inserted into the narrowing of the coronary artery, and under the guidance and monitoring of medical imaging equipment, the balloon is filled with diluted contrast medium It is a basic coronary heart disease treatment technique, that is, a small opening is opened on the blood vessel, and the catheter passes through the blood vessel to the heart and other parts for treatment. diagnosis and treatment.

The Y-connector is a necessary appliance for interventional therapy. The Y-connector is mainly used in conjunction with a balloon dilation catheter to assist in the introduction of contrast agents, guide wires or other medical devices during interventional procedures, and to control blood backflow and provide fluid access to the interventional system when using a guide catheter or dilation catheter. In the existing design, the cup sleeve used to connect the puncture needle on the Y-shaped connector and the main body of the Y-valve are sealed and connected with a rubber ring, which will cause the possibility of chemical contamination; and, when the balloon dilation catheter is inserted into the coronary artery stenosis During the catheterization operation, due to the blood overflow when the blood vessel is punctured, although the medical staff operate carefully and skillfully, there are still blood stains on the gloves of the medical staff, on the towel of the patient's body, and even under the operating table, which may also cause secondary accidents. Secondary contamination or cross-infection.

Therefore, how to design a Y-shaped connector that reduces chemical pollution and prevents blood overflow is a technical problem to be solved urgently in the industry.

Utility model content

The technical problem to be solved by this utility model is to overcome the deficiencies of the above-mentioned prior art, and provide a Y-shaped connector that reduces chemical pollution and prevents blood overflow, which can solve the deficiencies of the prior art, without installing rubber sealing rings, and at the same time avoids secondary pollution or cross-infection.

The technical solution adopted by the utility model to solve the above-mentioned technical problems is: a Y-shaped connector, including a Y-valve main body, a right lock cap connected to one end of the Y-valve main body, and an injection valve extending outward from the middle of the Y-valve main body and communicating with its interior. A connector and a cup sleeve for connecting a puncture needle or a catheter. The other end of the Y valve body is used for puncture with an interference fit to seal the connection cup sleeve. A seal for sealing the Y valve is provided between the right lock cap and the Y valve body. The silicone plug of the main body channel has a hole for introducing the guide wire.

The main body of the Y valve is threadedly connected with the right lock cap. The inner side of the main body of the Y valve is in the shape of a stepped hole, and the silicone plug is arranged in the stepped hole. The convex plate, the convex plate fixes the rubber plug through the washer.

The right lock cap, the main body of the Y valve, and the cup sleeve are made of medical-grade transparent polycarbonate material.

The outer circumference of the right lock cap is provided with a vertical strip-shaped protrusion for anti-slip rotation.

Compared with the prior art, the utility model has the advantages of convenient operation and simple structure. There is no need to install a rubber sealing ring at the connection between the main body of the Y valve and the cup sleeve, which avoids chemical pollution and prevents liquid leakage caused by the aging of the sealing ring; the silicone plug is squeezed by rotating the right lock cap to achieve a leak-proof seal , to prevent blood overflow, and bring convenience to the operation of medical staff; the Y-shaped connector is designed with transparent material, which can be more clearly identified, and is convenient for observation and operation.

Detailed ways

The utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

Please refer to Figure 1 to Figure 2, the utility model relates to a Y-shaped connector, including a Y valve body 4, a right lock cap 1, a silicone plug 3, and a cup sleeve 5, one end of the Y valve body 4 is connected to the right lock cap 1 , the other end is connected to the cup sleeve 5, the silicone plug 3 is set between the Y valve main body 4 and the right lock cap 1, the silicone plug 3 is provided with a hole, and an injection joint 6 is provided extending outward from the middle of the Y valve main body, and the injection joint 6 It communicates with the inside of the main body 4 of the Y-valve, and the injection joint 6 is mainly used for connecting with other medical devices and injecting medicines such as contrast medium, so as to facilitate operation.

In this embodiment, the interior of one end of the Y valve body 4 is in the shape of a stepped hole, and a silicone plug 3 is provided in the stepped hole. Through threaded connection, the inner lower end of the right lock cap 1 extends toward the inner side of the upper end of the Y valve main body 4, and a convex plate is provided. The convex plate fixes the rubber plug 3 through the gasket 2, and the right lock cap 1 compresses the silicone plug 3 by pressing the knob. Thereby closing the passage of the main body of the Y valve, otherwise, opening the passage of the main body of the Y valve. The outer circumference of the right lock cap 1 is provided with vertical strip-shaped protrusions, which play the role of anti-slip rotation.

The other end of the Y-valve main body 4 is used for puncture with an interference fit and sealing connection to the cup sleeve 5, and the cup sleeve 5 is used to connect the puncture needle or catheter, etc. There is no need to install a rubber sealing ring between the Y-valve main body 4 and the cup sleeve 5 to reduce chemical pollution , to prevent the leakage problem caused by the aging of the sealing ring.

The right lock cap 1, the Y valve body 4, the cup sleeve 5, and the injection joint 6 are all made of transparent materials, such as medical-grade transparent polycarbonate materials, etc. The transparent Y-shaped connector is more clearly identified and easy to observe.

Introduce the working process of the present utility model below, only illustrate, and the present utility model can also be applied in the interventional operation of different diseases, and basic principle is interlinked. First connect the puncture needle with the cup sleeve 5, tighten the right lock cap 1 before the operation, and the pores of the silicone plug 3 are in a closed state, so that the blood in the blood vessel will not overflow and eject during the puncture; Inject appropriate amount of heparin and normal saline into the main body 4 of the Y valve to exhaust the air and prevent blood coagulation. When emptying, a little air is left at the cup sleeve 5. The purpose of leaving a little air is that the blood can be recovered when the puncture needle punctures the blood vessel. If there is blood backflow in the Y-shaped connector immediately, it means that the puncture needle has penetrated; the guide wire passes through the silicone plug 3 smoothly, and then passes through the puncture needle into the blood vessel cavity, along the The guide wire is used to pull out the puncture needle, and then the guide wire is used to guide the balloon dilation catheter, so as to ensure the success of the catheter puncture operation. It avoids unnecessary secondary pollution and cross-infection during the operation, and brings great convenience to the operation of medical workers.

The above specific embodiments are only used to illustrate the structure of the present utility model, those of ordinary skill in the art can make various deformations and changes under the concept of the present utility model, and these deformations and changes are all included in the protection scope of the present utility model within.
