Example 1

As shown in FIG. 1, the application of the present invention provides a joint for an hydrotubation device to solve the above-mentioned problems. The joint of the oviduct liquid instillation device comprises a tee joint 1 and a liquid bag 3 connected with one end of the tee joint 1 through a valve 2. The tee 1 has a first port 10, a second port 11 and a third port 12. The liquid sac 3 is communicated with a third port 12 through a valve 2. In an optimized scheme, a valve is arranged between the valve 2 and the third port 12.

The outer side pipe wall of the first port 10 is provided with a plurality of sealing rings 13, the sealing rings 13 can be molded with the outer pipe wall of the first port 10 into an integrated piece during manufacturing, when the tee joint is used, the first port 10 is used for being inserted into the liquid through pipe orifice 40 at the bottom end of the liquid through pipe, so that the first port 10 of the tee joint 1 is connected with the liquid through pipe orifice 40, and the sealing rings 13 can enable the liquid through pipe orifice 40 to be tightly and hermetically connected with the first port 10. After the liquid through pipe orifice 40 is hermetically connected with the first port 10, a sealing sleeve 14 is sleeved on the outer pipe wall of the liquid through pipe orifice 40, so that the sealing connection effect is further enhanced.

The second port 11 is internally provided with a socket 15 and a valve flap 16 with a slit in sequence from bottom to top, when in use, a conical head or a needle of the injector is pushed from the socket 15, penetrates through the slit on the valve flap 16 and is pushed into the tee joint 1, and when the injector is withdrawn, the slit on the valve flap 16 is automatically closed to form unidirectional liquid flow. The first port 10, the second port 11, the third port 12, the sealing ring 13, the socket 15 and the valve flap 16 are integrally formed by medical silicon rubber.

The third port 12 is communicated with one end of the valve 2, the other end of the valve 2 is communicated with the liquid bag 3, namely, one end of the valve 2 far away from the third port 12 is connected with the liquid inlet of the liquid bag 3. The liquid bag 3 is an elastic structure which can be expanded into a spherical bag body. The valve 2 is of a bidirectional ventilation type and is made of rubber materials. The valve 2 is in a closed state when no pressure acts on the valve, can be opened when being stressed by tension, and can be automatically closed after the action disappears. When the liquid sac 3 is operated, the valve 2 can realize the function of stopping immediately, so that the liquid sac 3 can be fixed in any size state.

When the liquid-free infusion apparatus is used, the liquid-passing tube enters the uterine cavity-near end of the fallopian tube at one side under the guidance of the guide wire, the first port 10 of the tee joint 1 is hermetically connected with the liquid-passing tube opening 40 at the bottom end of the liquid-passing tube, the second port 11 is connected with the injector, liquid is injected into the liquid-passing tube through the injector, and at the moment, if the liquid bag 3 is not bulged, no pressure exists in the front, and the side is unobstructed; if the liquid bag 3 swells, the front blockage is explained, the liquid flows backwards, because the second port 11 is a one-way channel, the liquid flows into the liquid bag 3 through the third port 12, at the moment, the liquid bag 3 is repeatedly squeezed, pulse type impact under normal pressure is realized, the adhesion is tried to be released, if the liquid bag is invalid, the liquid bag 3 is closed (a manual deflation mode or a valve is closed), the injector is pressurized and impacted, then the liquid bag 3 is opened, and whether the liquid returns exists or not is observed.

Example 2

Referring to fig. 2, an embodiment of the present invention provides an oviduct instillation device, which comprises an oviduct instillation device connector 100, an instillation tube 4, an instillation injector 5, a membrane sac tube 6, a one-way valve 7 and an expansion sac injector 8. The hydrotubation device connector 100 is the hydrotubation device connector described in example 1. Figure 2 is also a schematic representation of the use of the hydrotubation connector 100 in example 1.

The upper end of the liquid through pipe 4 is provided with a liquid outlet and extends into the uterine cavity 9, and the liquid through pipe opening 40 at the lower end is hermetically connected with the first port 10 of the tee joint 1. The liquid-through injector 5 is connected with the second port 11, namely, when the liquid-through injector 5 is used, the conical head or the needle head at the upper end is pushed from the socket 15, penetrates through the seam on the valve flap 16 and is pushed into the tee joint 1, and after the liquid-through injector 5 is withdrawn, the seam on the valve flap 16 is automatically closed. The membrane bag pipe 6 is parallel and the integrative flexible membrane bag pipe that sets up with logical liquid pipe 4, and membrane bag pipe 6 and logical liquid pipe 4 are for moulding plastics an organic whole, and 6 tops of membrane bag pipe correspond the neck of uterus department of endocervix of palace chamber 9 and are equipped with membrane bag 60, and membrane bag 60 is the spherical utricule that can expand to encircle logical liquid pipe 4. The bottom end orifice of the membrane bag tube 6 is connected with a bag expanding injector 8 through a one-way valve 7. The upper end and the lower end of the check valve 7 are respectively identical to the first port 10 and the second port 11 in structure. When in use, gas or liquid is injected into the membrane sac tube 6 through the expansion sac injector 8, so that the membrane sac 60 is expanded into a spherical sac body, and the membrane sac 60 is just sealed on the inner cervix opening of the uterine cavity 9 to play a role of mechanical obstruction. Due to the tight seal of the membrane 60, when the pressure in the uterine cavity 9 is gradually increased, the liquid does not overflow from the inner opening of the cervix and flows to the umbrella end of the fallopian tube. The balloon inflation syringe 8 is used to inject liquid or gas into the balloon tube 6 to inflate the balloon 60.

The specific operation process comprises the following steps: firstly, the top end of a liquid through pipe 4 is placed in a uterine cavity 9 according to the operation specification, the top end of the liquid through pipe enters the uterine tube near the uterine cavity end on one side under the guidance of a guide wire, a membrane bag 60 is positioned at the position of the cervix of the uterine cavity 9, then gas or liquid is injected into the membrane bag pipe 6 by a swelling bag injector 8, the membrane bag 60 is expanded into a spherical bag body, the membrane bag 60 is just sealed on the cervix of the uterine cavity 9, then liquid is injected into the liquid through pipe 4 by the liquid through injector 5 and enters the uterine cavity, meanwhile, the liquid bag 3 is observed, if the liquid bag 3 does not swell, no pressure exists in the front, the transfusion is smooth, if the liquid bag 3 swells, the front blockage is indicated, the liquid flows backwards, because the second port 11 is a one-way channel, the liquid flows into the liquid bag 3 through the third port 12, at the moment, the liquid bag 3 can be repeatedly extruded, the impact under normal pressure can be carried out under normal pressure, the adhesion can be attempted to be released, and if the liquid bag 3 is ineffective, the fallopian tube can be manually deflated or a valve is closed, the liquid-through syringe 5 is pressurized and impacted, and then the liquid sac 3 is opened to see whether liquid returns or not.

The present embodiment is not described in detail, and is a technique known in the art.

The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily think of various changes or substitutions within the technical scope of the present invention, which should be covered by the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
