[0019] like Figures 1 to 3As shown, the utility model provides an aseptic disconnector, comprising a female head 1 and a male head 2 clamped in the female head 1 by a clamping assembly, wherein the female head 1 comprises a female head shell 8, a liquid channel 7 is provided at the liquid inlet end of the female head shell 8, a step 12 is provided in the female head shell 8, the step 12 divides the inner cavity of the female head shell 8 into a male head accommodating cavity and a plug accommodating cavity, the male head 2 is inserted into the male head accommodating cavity, and an internal plug 11 is provided in the plug accommodating cavity; the male head 2 comprises a male head shell 9, a liquid channel 2 10 is provided at the liquid outlet end of the male head shell 9, a step 2 15 is provided on the inner wall of one end of the male head shell 9 close to the female head 1, and an internal plug 2 13 is provided in the male head shell 9; when the male head 2 is not inserted into the female head 1, the internal plug 11 presses against the female head 1. The internal blockage 13 is against the step 12 and is sealed with the step 12, and the internal blockage 13 is against the step 2 15 and is sealed with the step 2 15, thereby preventing the liquid from flowing into the male head 2 through the liquid channel 1 7. When the male head 2 is inserted into the female head 1, the internal blockage 11 is separated from the step 12, and the internal blockage 2 13 is separated from the step 2 15, so that the liquid can flow from the liquid channel 1 7 to the liquid channel 2 10 for discharge; in the initial state, the male head 2 is in the state of being inserted into the female head 1, so that the liquid can flow directly, avoiding the internal parts from contacting the external environment, and ensuring that the interior of the device is always in a sterile state. After use, the male head 2 can be removed by pressing the snap-fit assembly. The device cannot be used anymore after use, so this device is a disposable product.

[0020] Furthermore, the internal blocker 11 is connected to the inner wall of the female head shell 8 through a return spring 12. At the same time, a groove 3 21 is provided at the contact point between the internal blocker 11 and the step 12, and an O-ring 3 22 is sleeved outside the groove 3 21, so that when there is no external force, the O-ring 3 22 contacts the step 12 to form a sealed connection.

[0021] Similarly, the internal blocker 13 is connected to the inner wall of the male head shell 9 through the return spring 14. At the same time, a groove 16 is provided at the contact point between the internal blocker 13 and the step 15, and an O-ring 17 is sleeved outside the groove 16, so that when there is no external force, the O-ring 17 contacts the step 15 to form a sealed connection.

[0022] When the male connector 2 is inserted into the female connector 1, the top of the internal blocker 11 collides with the top of the internal blocker 2 13, thereby compressing the return spring 12 and the return spring 2 14. At this time, the O-ring 3 22 disengages from the step 12, and the O-ring 1 17 disengages from the step 2 15. At the same time, the male connector 2 is clamped in the female connector 1 through the clamping assembly, so that the channel continues to exist.

[0023] Specifically, the snap-fit assembly includes a protrusion 2 provided on the outside of the female head 1, and the button 4 is elastically connected to the protrusion 2 through a spring 5. The combination of the button 4 and the protrusion 2 forms a cavity 3, and the spring 5 is placed in the cavity 3. At the same time, a limiting ring 6 is connected to the button 4, and a step three 20 is provided on the outer wall of the male head 2. When the male head 2 enters and exits the female head 1, the limiting ring 6 clamps the step three 20, and when the button 4 is pressed, the limiting ring 6 disengages from the step three 20, so that the male head 2 can be taken out.

[0024] Furthermore, in order to prevent the liquid from flowing out of the second liquid channel 10 and leaking directly from the male head accommodating cavity of the female head 1, a second groove 19 is provided on the outer wall of the male head 2, and the second O-ring 18 is sleeved on the second groove 19. Then, when the male head 2 is inserted into the female head 1, the second O-ring 18 forms a sealed connection with the inner wall of the female head 1.

[0025] The working principle of this utility model is:

[0026] In the initial state, the male connector 2 is inserted into the female connector 1, the liquid inlet pipe is connected to the liquid channel 1 7, and the liquid outlet pipe is connected to the liquid channel 2 10. The liquid flows in from the liquid channel 1 7, flows into the male connector shell 9 through the blockage accommodating cavity of the female connector shell 8, and then flows out from the liquid channel 2 10. The entire operation is aseptic. After use, press the button 4 to separate the male connector 2 from the female connector 1. At the same time, the internal blockage 11 blocks the inner cavity of the female connector 1, and the internal blockage 2 13 blocks the inner cavity of the male connector 2 to prevent the liquid from flowing out from the non-liquid channel.

[0027] The device mainly ensures that the fluid path is kept sterile when the fluid closed system is disconnected. At the same time, the device also takes into account the convenience of operation and sterility assurance, which is conducive to popularization and use.

[0028] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
