[0018] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0019] 1. The present utility model discloses a sterile connector. When using the sterile connector assembly, the upper connector component, the lower connector component and the sealing paper are pre-assembled. The sealing paper is respectively located between the upper connector component and the lower connector component, and the end of one side of the sealing paper passes through the gap between the pull plate and the connector, and the end extends to the external environment. First, the pull plate and the connector are installed. For example, the pin on one side of the first pull plate is snapped into the card slot on one side of the first connector, and the first pull plate rotates around the card slot and locks itself to the first connector by using the buckle. At this time, the first connector and the first pull plate are assembled. Similarly, the second pull plate and the second connector are installed in the same way. Then, the two sets of assembled upper connector components and lower connector components are assembled. The first pull plate and the second pull plate are corresponding up and down, and the first connector and the second connector are corresponding up and down. At this time, the lower buckle and the first through slot are correspondingly engaged, and the second through slot and the upper buckle are correspondingly engaged. The two pull plates are assembled by using their own buckling positions. At the same time, the two upper sliding plug plates and the two lower plug cavity plates are correspondingly arranged, and the operator slides the upper sliding plug plate into the lower plug cavity plate. At this time, the upper sliding plug plate and the lower plug cavity plate are engaged, and then the upper connector component and the lower connector component are fixedly assembled. At this time, the two rubber sealing plugs on the upper and lower sides are mutually extruded and fitted, and then the sealing paper seals the rubber plugs into the connector to form a sterile environment. After the connector is assembled, the sealing paper is pulled out and removed from the sterile connector assembly, realizing the sterile connection between the upper connector component and the lower connector component. This setting facilitates the operator to assemble and disassemble between the upper connector component and the lower connector component, without the need to rely on additional engaging components, and the operation is simple and fast, improving the working efficiency of the device.

[0020] 2. The utility model discloses a sterile connector. When it is necessary to transfer medical liquid by using the sterile connector assembly, the sterile connector assembly can be assembled with an external hose through an anti-detachment assembly. Two groups of external hoses are respectively installed with two groups of anti-detachment assemblies. One end of a group of external pipelines is inserted into a through pipe, and the external pipeline passes through the inside of the installation cavity box until the end of the external pipeline is inserted into the inside of the connecting pipeline and extends to one side close to the rubber sealing plug. At this time, one group of external pipes is docked and communicated with one group of connecting pipelines. At the same time, the external pipe is located between two arc-shaped plates. Then the operator rotates the rotary knob, which drives the positive and negative thread screw rod to rotate forward. The positive and negative thread screw rod drives two left moving plates to move closer to each other. At this time, the two left moving plates move closer to each other along the positive and negative thread screw rod. Then the two arc-shaped plates will move closer to each other until the two arc-shaped plates tightly clamp and fix both sides of the external pipeline. A sealing pad is arranged on the inner wall of the arc-shaped plate, which is beneficial to improving the clamping stability of the arc-shaped plate. And the anti-detachment effect is achieved between the clamped and stable group of external pipelines and the corresponding group of connecting pipelines. Both groups of connecting pipelines are installed and fixed with the external pipeline through the anti-detachment assembly. After the installation is completed, the operator feeds materials into a group of external pipelines, and the medical materials will flow through the sterile connector assembly for output work, and the materials will be output from the other group of external pipelines. This setting realizes the purpose of clamping and fixing the external pipeline through the anti-detachment assembly, so that the anti-detachment effect is achieved between the connecting pipeline and the external pipeline, and the installation and disassembly of the anti-detachment assembly are both convenient, improving the practicability of the device.

[0038] In summary, the working principle: The present utility model discloses a sterile connector. When using the sterile connector assembly 1, first assemble the upper connector part 11, the lower connector part 12 and the sealing paper. The sealing paper is respectively located between the upper connector part 11 and the lower connector part 12, and the end of one side of the sealing paper passes through the gap between the pull plate and the connector, and the end extends to the external environment; first install the pull plate and the connector. For example, snap the pin on one side of the first pull plate 113 into the card slot on one side of the first connector 111. The first pull plate 113 rotates around the card slot and locks itself with the first connector 111 by using the buckle. At this time, the assembly of the first connector 111 and the first pull plate 113 is completed. Similarly, install the second pull plate 123 and the second connector 121 in the same way; then assemble the two sets of assembled upper connector parts 11 and lower connector parts 12. The first pull plate 113 and the second pull plate 123 are corresponding up and down, and the first connector 111 and the second connector 121 are corresponding up and down. At this time, align the lower buckle 124 with the first through groove 114 and snap them together, align the second through groove 125 with the upper buckle 115 and snap them together, and assemble the two pull plates together by using their own buckling positions; at the same time, align the two upper sliding plug plates 112 with the two lower plug cavity plates 122 respectively, and the operator slides the upper sliding plug plate 112 into the lower plug cavity plate 122. At this time, the clamping between the upper sliding plug plate 112 and the lower plug cavity plate 122 is completed, and then the fixing assembly work between the upper connector part 11 and the lower connector part 12 is completed. And at this time, the two rubber sealing plugs 13 on the upper and lower sides are pressed against each other and fitted, and then the sealing paper seals the rubber plugs into the connector to form a sterile environment. After the connector is assembled, pull out and remove the sealing paper from the sterile connector assembly 1 to achieve a sterile connection between the upper connector part 11 and the lower connector part 12. This setting facilitates the operator to assemble and disassemble between the upper connector part 11 and the lower connector part 12, without the need to rely on additional clamping components, and the operation is simple and fast, improving the working efficiency of the device;

[0039] When it is necessary to transfer medical liquids using the sterile connector assembly 1, the sterile connector assembly 1 can be assembled with the external hose through the anti-detachment assembly 2. Two groups of external hoses are respectively installed with two groups of anti-detachment assemblies 2. One end of a group of external pipelines is inserted into the through pipe 24, and the external pipeline passes through the inside of the installation cavity box 21 until the end of the external pipeline is inserted into the connection pipeline 3 and extends to the side close to the rubber sealing plug 13. At this time, a group of external pipes are docked and communicated with a group of connection pipelines 3. At the same time, the external pipe is between two arc-shaped plates 28. Then the operator rotates the rotation knob 23, and the forward and reverse thread screw rod 26 driven by it will rotate forward. The forward and reverse thread screw rod 26 drives two left moving plates 291 to move closer to each other. At this time, the two left moving plates 291 move closer to each other along the forward and reverse thread screw rod 26. Then the two arc-shaped plates 28 will move closer to each other until the two arc-shaped plates 28 tightly clamp and fix both sides of the external pipeline. A sealing pad is arranged on the inner wall of the arc-shaped plate 28, which is beneficial to improving the clamping stability of the arc-shaped plate 28. And the anti-detachment effect is achieved between a group of external pipelines clamped stably and the corresponding group of connection pipelines 3. Both groups of connection pipelines 3 are installed and fixed with the external pipeline through the anti-detachment assembly 2. After the installation is completed, the operator feeds materials into a group of external pipelines. The medical materials will flow through the sterile connector assembly 1 for output work, and the materials will be output from the other group of external pipelines. If it is necessary to disassemble the external pipeline and the sterile connector assembly 1, rotate the rotation knob 23 in the reverse direction. The forward and reverse thread screw rod 26 rotates in the reverse direction. The forward and reverse thread screw rod 26 will drive the two arc-shaped plates 28 to move away from each other. At this time, both arc-shaped plates 28 will move away from the external pipeline until the arc-shaped plates 28 give up the clamping effect on the external pipeline. The user can then pull out the external pipeline in the direction away from the connection pipeline 3 to disassemble the anti-detachment assembly 2 from the external pipeline. This setting realizes the purpose of clamping and fixing the connection of the external pipeline through the anti-detachment assembly 2, so that the anti-detachment effect is achieved between the connection pipeline 3 and the external pipeline. And the installation and disassembly operations of the anti-detachment assembly 2 are both convenient, improving the practicability of the device.
