[0030] The present application provides an implantable rapid liquid filling and discharging device, which is described in detail below. It should be noted that the order of description of the following embodiments does not limit the preferred order of the embodiments of the present application. In addition, in the following embodiments, the description of each embodiment has its own emphasis. For parts not detailed in one embodiment, please refer to the relevant description of other embodiments.

[0031] To solve the technical problem of complicated and difficult operation and use of liquid discharge devices in the prior art, an embodiment of the present application provides an implantable rapid liquid filling and discharge device, which is described in detail below.

[0032] like Figures 1 to 4 As shown, an implantable rapid liquid filling and discharging device includes

[0033] A valve body 1, the valve body 1 being adapted to be inserted into human skin 6, the inner end of the valve body 1 being provided with a connection joint 2, the connection joint 2 being adapted to be connected to an implantable device in the body, the outer end of the valve body 1 extending out of the human skin 6, the valve body 1 being provided with a skin gasket 4;

[0034] A connecting joint 2 is provided with a connecting hole, which is communicated with the inner cavity of the valve body 1;

[0035] The valve stem 3 is arranged in the valve cavity of the valve body 1. A boss 31 is formed in the middle of the valve stem 3. A plurality of grooves are circumferentially provided on the outer wall of the boss 31. The valve stem 3 outside the boss 31 is sequentially composed of a cylindrical rod 32 and a cross rod 33. A sealing ring is sleeved on the cylindrical rod 32. A spring 5 is arranged between the valve stem 3 and the connecting joint 2. One end of the spring 5 abuts the connecting joint 2, and the other end abuts the boss 31. The spring 5 abuts the valve stem 3 toward the outer end of the valve body 1 to form a seal between the valve stem 3 and the inner wall of the valve body 1.

[0036] Specifically, as an optional implementation in this embodiment, Figure 2 As shown, the valve body 1 is provided with an external thread, the skin gasket 4 is provided with an internal threaded hole, and the valve body 1 is connected to the internal threaded hole of the skin gasket 4 via the external thread.

[0037] Specifically, as an optional implementation in this embodiment, Figure 2 As shown, a plurality of fixing holes 41 are provided on the skin pad 4 .

[0038] Under normal circumstances, the skin pad 4 can be fixed on the skin by a sticker. If the sticker cannot stably fix the skin pad 4, a needle and suture can be passed through the fixing hole 41 to fix the skin pad 4 to the skin.

[0039] Specifically, as an optional implementation in this embodiment, Figure 2 Figure 3 As shown, a card slot 11 is provided on the outer port of the valve body 1 .

[0040] The valve body 1 is connected to an external device via the card slot 11 , and the external device can drive the valve body 1 to rotate via the card slot 11 , thereby adjusting the angle of the device implanted in the body.

[0041] Specifically, as an optional implementation in this embodiment, Figure 2 As shown, the cavity opening at the outer end of the valve cavity is a tapered expansion structure. The tapered expansion facilitates the pressing operation of the valve stem 3.

[0042] Specifically, as an optional implementation in this embodiment, Figure 2 As shown, an insertion section is formed on the connecting joint 2, and the connecting joint 2 is sealed and fixedly connected to the valve body 1 via the insertion section.

[0043] The working principle of the implantable rapid liquid filling and discharging device of the utility model is as follows: the spring 5 applies pressure to the blocking valve stem 3, so that the valve stem 3 presses the sealing ring, so that the entire valve body 1 is sealed. When in use, it is only necessary to move the valve stem 3 toward the inside of the connecting joint 2 to loosen the sealing ring, so that the exchange of internal and external environments can be achieved;

[0044] The external skin-fitting pad adheres tightly to the skin surface to form a sterile space. When not in use, apply the sterile patch and return to normal life.
