The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0026] Example 1

[0027] like Figure 1 The diagram shows a multi-connector hemodialysis bag, including a dialysis bag body 5. The dialysis bag body 5 is provided with a sampling connector 51, a first connector 52, and a second connector 53. The first connector 52 is used to connect with a puncture-type APD dialysis device, and the second connector 53 is used to connect with a Luer lock-type APD dialysis device.

[0028] like Figures 2-7 As shown, the second connector 53 includes a housing 1, a housing 2, and a flexible barrier 3. A flow channel 11 is provided on the housing 1. The housing 2 is mounted on the housing 1, and a cavity 21 is provided inside the housing 2. The cavity 21 is connected to the flow channel 11. A through hole 22 is provided at the end of the housing 2 away from the housing 1, and the through hole 22 is connected to the cavity 21. The flexible barrier 3 is provided inside the cavity 21; in this embodiment, the flexible barrier 3 is a silicone barrier. A countersunk hole 31 is provided near the housing 2 on the flexible barrier 3, and the countersunk hole 31 is connected to the flow channel 11. A cutting slit 32 is provided at the end of the flexible barrier 3 near the through hole 22, and the thickness of the flexible barrier 3 at the cutting slit 32 is 1-3 mm. The countersunk hole 31 is connected to the cutting slit 32. The inner wall of the cavity 21 near the through hole 22 is a conical arc surface 23, and the taper of the conical arc surface is 1.62°-1.82°. The flexible barrier 3 near the through hole 22 is interference-fitted with the housing 2.

[0029] When the joint is not connected, the flexible barrier 3 with the cutting seam 32 at one end is accommodated in the housing 2, where the flexible barrier 3 and the housing 2 are in interference fit, and the cutting seam 32 is tightly closed under the extrusion of the housing 2, and the liquid in the flow passage 11 cannot flow out from the joint. The tapered camber 23 is arranged to facilitate the end of the flexible barrier 3 to be extruded into the housing 2 during installation, and the housing 2 has a certain extrusion force on the end of the flexible barrier 3 to improve the sealing performance of the cutting seam 32 when closed.

[0030] When it is needed to be connected, the connector or connecting pipe is inserted into the through hole 22 to extrude the end of the flexible barrier 3 with the cutting seam 32, and the end of the flexible barrier 3 is extruded into the wider part of the cavity 21, and the flexible barrier 3 is continuously extruded to deform in the direction of the counterbore 31, so that the end of the flexible barrier 3 is in a stretched state, thereby opening the cutting seam 32.

[0031] The seal protection cap 4 is detachably installed on the housing 2 near one end of the through hole 22. The housing 2 and the seal protection cap 4 are connected by threads. The seal protection cap 4 further improves the sealing performance of the quick connector.
