Description

Technical Field

[0001] This invention relates to the field of tee connector technology, and more particularly to a tee connector. Background Technology

[0002] Currently, multi-port valves are widely used in the medical device field to control the flow of different tubing. They allow for easy switching of different flow rates according to the patient's required infusion flow, achieving multiple functions in one product. They are mainly used in disposable infusion pumps, disposable infusion sets, disposable sterile stopcocks, disposable T-connectors, etc., thus becoming one of the main components for realizing product functions. However, due to the multiple interfaces in a T-connector, the risk of infection increases. Therefore, in clinical practice, sterile medical dressings are often used to wrap medical T-connectors.

[0003] However, existing tee connectors have the following drawbacks:

[0004] (1) The medical dressing is made of soft material and will directly adhere to the surface of the medical tee, making it difficult to protect the medical tee from pressure. Utility Model Content

[0005] In order to solve one or more technical problems existing in the prior art, the purpose of this application is to provide a three-way connector that can isolate the three-way valve from the outside and provide rigid support.

[0006] To address the aforementioned technical problems, one of the objectives of this application is achieved through the following technical solution:

[0007] A three-way connector includes a three-way valve with three connectors connected to it. The three-way valve has two protective shells on its upper cover, which are connected to each other. A base plate is provided on the inner side of the two protective shells, which is located below the three-way valve. The protective shells have through holes for the connectors or the three-way valve to pass through. Four limiting components are symmetrically fixed on the bottom of the base plate, which limit the movement of the protective shells.

[0008] Furthermore, the limiting component includes a mounting shell fixedly disposed at the bottom of the base plate, a slot opened on the inner side wall of the mounting shell and corresponding to the mounting shell, a limiting cylinder through the outer side wall of the mounting shell and capable of being inserted into the slot, and a threaded rod through the other outer side wall of the mounting shell and threadedly connected to the limiting cylinder, wherein the limiting cylinder is slidably connected to the inner side wall of the mounting shell.

[0009] Furthermore, sliding grooves are provided on both the upper and lower side walls of the mounting housing, and sliding rods that are fixedly connected to the limiting cylinder are slidably connected in the sliding grooves.

[0010] Furthermore, the connector head is provided with a blocking cap.

[0011] Furthermore, the through hole located at the top of the protective shell extends uniformly to the edge.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] (1) When in use, the two protective shells are placed on the three-way valve and the base plate is placed inside the two protective shells. Then the limiting component is used to limit the protective shells. In this way, the three-way valve can be isolated from the outside and can be rigidly supported. Compared with the existing technology, it solves the technical problem that the medical dressing material is soft and will directly adhere to the surface of the medical three-way valve, making it difficult to protect the medical three-way valve under pressure.

[0022] Example 1:

[0023] like Figures 1-4 As shown, this embodiment provides a three-way connector, which includes a three-way valve 1. Three connectors 2 are connected to the three-way valve 1. Two protective shells 5 are provided on the top cover of the three-way valve 1. The two protective shells 5 are connected to each other. A base plate 6 is provided inside the two protective shells 5. The base plate 6 is located below the three-way valve 1. A through hole 4 is provided on the protective shell 5 for the connectors 2 or the three-way valve 1 to pass through. Four limiting components 12 are symmetrically fixed on the bottom of the base plate 6. The limiting components 12 play a limiting role for the protective shells 5.

[0024] The three-way connector includes a three-way valve 1, three connectors 2 connected to the three-way valve 1, and two protective shells 5 covering the three-way valve 1, with the two protective shells 5 interlocking. A base plate 6 is located inside the two protective shells 5, below the three-way valve 1. Through holes 4 are formed in the protective shells 5 for the connectors 2 or the three-way valve 1 to pass through. Four limiting components 12 are symmetrically fixed to the bottom of the base plate 6, limiting the position of the protective shells 5. In use, the two protective shells 5 are placed over the three-way valve 1, and the base plate 6 is placed inside the two protective shells 5. The limiting components 12 then limit the position of the protective shells 5. This method isolates the three-way valve 1 from the outside and provides rigid support. Compared to existing technologies, this solves the technical problem that soft medical dressings directly adhere to the surface of the medical three-way connector, making it difficult to provide pressure protection.

[0025] Furthermore, the limiting component 12 includes a mounting shell 8 fixedly disposed at the bottom of the base plate 6, a slot 13 opened on the inner side wall of the mounting shell 8 and corresponding to the mounting shell 8, a limiting cylinder 7 that passes through the outer side wall of the mounting shell 8 and can be inserted into the slot 13, and a threaded rod 11 that passes through the other outer side wall of the mounting shell 8 and is threadedly connected to the limiting cylinder 7. The limiting cylinder 7 is slidably connected to the inner side wall of the mounting shell 8.

[0026] The limiting assembly 12 includes a mounting shell 8 fixedly mounted on the bottom of the base plate 6. A slot 13 corresponding to the mounting shell 8 is formed on the inner wall of the mounting shell 8. A limiting cylinder 7, capable of being inserted into the slot 13, passes through the outer wall of the mounting shell 8. A threaded rod 11, threadedly connected to the limiting cylinder 7, passes through the other outer wall of the mounting shell 8. The limiting cylinder 7 is slidably connected to the inner wall of the mounting shell 8. In use, by screwing the threaded rod 11, the threaded rod 11 moves the limiting cylinder 7, ultimately inserting the limiting cylinder 7 into the slot 13, thereby limiting the protective shell 5.

[0027] Furthermore, sliding grooves 10 are provided on both the upper and lower side walls of the mounting housing 8, and sliding rods 9, which are fixedly connected to the limiting cylinder 7, are slidably connected within the sliding grooves 10. This method serves to limit the movement of the limiting cylinder 7.

[0028] Furthermore, the connector 2 is equipped with a blocking cap 3, which serves to limit and block the protective shell 5, preventing the protective shell 5 from moving outward.

[0029] Furthermore, the through hole 4 located at the top of the protective shell 5 extends consistently to the edge, facilitating the installation of the protective shell 5.

[0030] The above embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of protection of this application. Any non-substantial changes and substitutions made by those skilled in the art based on this application shall fall within the scope of protection claimed by this application.
