Problems solved by technology
In the traditional structure, since the elastic cap body is a simple truncated cone shape or a double-layer truncated cone shape, the deformation is not directional when compressed, and it is easy to cause difficulty in rebounding. Taking the double-layer truncated cone shape as an example, it will also occur spontaneous deformation during deformation. The locking phenomenon makes the dosing process not smooth, and it is easy to cause drug leakage
In addition, it is difficult for the traditional structure to recover and block the liquid filling port after adding the medicine, which will cause the infusion tube to leak

Embodiment Construction
[0036] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0037] Such as figure 1 and 2 As shown, the Y-shaped needle-free medicated joint of the present invention includes an upper fixed end cover, a "Y"-shaped lower terminal and an elastic sealing plug cylinder. The upper fixed end cap is in the shape of a truncated cone with a small top and a big bottom.
[0038] Such as Figure 3-6 As shown, the "Y"-shaped lower terminal includes a main pipe and a branch pipe connected in a "Y" shape. The lower end of the main pipe is the main terminal, and the upper end of the main pipe is provided with a dosing column. An inner pipeline is provided, and a dosing through hole is set on the top side of the dosing column, the dosing through hole communicates with the inner pipeline, and the inner pipeline communicates with the main pipeline; an annular groove is arranged around the dosing column , an ...

The invention provides a Y-shaped needless medicine adding connector. The invention belongs to the field of medical instruments and in particular provides the needless medicine adding connector comprising an upper fixing end cap, a Y-shaped lower connecting end and an elastic sealing plug pillar body. The Y-shaped needless medicine adding connector is different from a conventional guideless double-layer table body type elastic sealing cap structure. During medicine adding, the upper portion of the elastic sealing plug pillar body is pierced by a medicine adding pillar under the pressure of an injection syringe; the upper portion, the middle portion and the lower portion of the elastic sealing plug pillar body retract along the medicine adding pillar until a medicine adding through hole of the medicine adding pillar is exposed; medicine in the injection syringe can enter a main pipeline and a branch pipeline via the medicine adding through hole and an inner pipeline smoothly without splashing and leaking. When the medicine adding is over, the elastic sealing plug pillar body retracts along the medicine adding pillar until the medicine adding pillar is completely covered and enclosed and the initial state that the inner wall of the inner pipeline seals the medicine adding through hole is restored; the seal is tight without dripping and leaking.
Description
technical field [0001] The invention belongs to the field of medical devices, and in particular relates to a needle-free drug-feeding joint. Background technique [0002] The traditional dosing joint generally adopts an external joint on the infusion tube, and the liquid filling port is blocked by an elastic cap inside the external joint. When in use, the elastic cap is pressed down so that the syringe is directly aligned with the liquid filling port for dosing injection. In the traditional structure, since the elastic cap body is a simple truncated cone shape or a double-layer truncated cone shape, the deformation is not directional when compressed, and it is easy to cause difficulty in rebounding. Taking the double-layer truncated cone shape as an example, it will also occur spontaneous deformation during deformation. The locking phenomenon makes the dosing process not smooth, and it is easy to cause drug leakage. In addition, it is difficult for the traditional structure...
