It is an object of the present invention to provide a dialyzer connector that does not cause deformation or anti-rotation force in the conduit after the connector is fixed, and does not cause a loosening phenomenon in the dialyzer connector.

  The dialyzer connector of the present invention is mainly composed of a connector and a connecting pipe, of which a screw is engraved on the connector, an upper body, a fitting protrusion, a fitting body, a groove tank, a lower body, a fitting groove, a cover body, and a groove tank. Of which a convex ring and an inner ring are installed in the connecting pipe, the connecting pipe is installed in the cover body, and the upper body and the lower body of the connector are connected to each other by the connecting section. The upper body and lower body are closed through the section, and the upper body fitting protrusion is fitted into the lower body fitting groove, and the upper body fitting body is press-fitted into the lower body cover body, and at the same time, the connecting pipe is fixed. In addition, the upper body and the lower body are both provided with a groove tank, and the convex ring of the connecting pipe slides inside thereof, and the dialyzer connector and the connecting pipe can rotate and slide.

The inventive step, practicality, and effects thereof can be summarized as follows when compared with conventional products.
《Conventional defects》
1. Since the dialyzer connector and the conduit are fixed, it is inconvenient to attach to the artificial kidney.
2,
After the connector is fixed, the conduit is likely to be twisted or deformed, the circulation of the conduit is not smooth, the flow rate is reduced, and the hemodialysis effect is reduced.
3,
After the conduit is deformed due to the screwing of the connector, a reverse rotational force is generated to restore the shape of the conduit, leading to loosening of the connector.
4. When the connector is loosened after receiving the third point, blood leakage may occur at the dialyzer connector in the hemodialysis process.
5. Medical personnel need to inspect the connector for looseness irregularly during the hemodialysis process.

<Advantages of the present invention>
1. Installation and removal from the artificial kidney is quick and easy.
2. Deformation of the conduit does not occur during installation and removal.
3. After installing the connector, it will not loosen due to the torque of the conduit.
4. In response to the third point, blood does not leak out.
5. Since there is a space for the conduit to move inside the connector, it is easy to control the tightness after the conduit is joined.
6. Since there is a space in which the connecting pipe moves inside the dialyzer connector, the connecting pipe and the dialyzer connector can be rotated and slid without being too tight, and the connector does not loosen and come off.
