Wherein, when the lower housing 18 and the upper housing 20 of the first connector bracket 12 are inserted into the first guiding space 243 and the second guiding space 263, the lower housing 18 and the upper housing 20 only It touches the outer ring shell 292, but does not touch the inner ring shell 291. Therefore, the friction between the lower case 18 / upper case 20 and the outer ring case 292 may be caused by mutual friction. The falling dust will only fall into the first guiding space 243 and the second guiding space 263 without contaminating the sterile first end portion 361 and the second end portion 461.

After the dialysate replacement process is completed, the first connector bracket 12 is rotated, for example, counterclockwise, to separate the first connector bracket 12 from the second connector bracket 16; in the drawing (not shown), a cap is used 14 clamp the new cap 34, and set the cap 14 on the first connector bracket 12 again, and rotate the cap 34 by rotating the cap 14 to rotate the cap 34, for example, clockwise to make the new cap 34 screw It is set and screwed on the first connector body 36 to ensure that the liquid of the infusion short tube 30 will not overflow.

In the above embodiment, the second connector bracket has a guiding space formed by the first / second inner casing and the first / second outer casing, and the first connector bracket is a single-layer casing. Therefore, when mating, the first connector bracket is inserted into the guide space of the second connector bracket, but it is not limited to this. In another embodiment, the first connector bracket can also be provided with an inner shell. The guiding space formed by the body and the outer shell, and the second connector bracket is a single-layer housing. Therefore, when the docking is performed, the second connector bracket is inserted into the guiding space of the first connector bracket. .

In summary, the present invention can achieve the following effects: 1) Using the pipe docking grip of an embodiment of the present invention, there is no need to change the first connector assembly of the existing infusion tube and the second connection of the dialysate tube The structure of the device assembly can be installed directly. 2) The first connector assembly and the second connector assembly are clamped by the pipe docking gripper, and then axially docked, which can provide assistance to patients with physical limitations such as vision loss or hand tremor, such as Close the eyes or complete the docking without seeing clearly, or avoid the patient's hand shaking and touching the sterile end of the connector assembly. 3) The pipe docking grip can be cleaned and reused or discarded. The pipe docking grip covers the sterile end of the connector assembly to provide physical isolation to prevent the end from contacting dust or other pollutants. Helps reduce the possibility of contamination when the infusion tubing and dialysate tubing are connected and disconnected. 4) Whether the first connector bracket or the second connector bracket has a double-layer housing structure in which a guiding space is formed by the inner shell and the outer shell in the pipe docking holder, the first connector bracket can be avoided. And the second connector bracket has the chance of falling and falling to the end after being butted and frictioned, so the combination of the first connector bracket and the second connector bracket can greatly reduce the chance of the end of the connector body being polluted. 5) The cap can be used to help unscrew the cap from the first connector body or screw the new cap back to the first connector body, so it can be used without touching the first connector body of the infusion tube. The sterile end is lifted before the docking and disconnection of the dialysate tube is completed.

Although the present invention has been disclosed as above with the examples, it is not intended to limit the present invention. Those with ordinary knowledge in the technical field to which the present invention pertains may make some modifications and retouching without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be determined by the scope of the appended patent application.
