Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. The accompanying drawings are only for illustrative purposes and are only schematic drawings rather than actual drawings, which are not intended to limit the present disclosure, and in order to better illustrate the embodiments of the present disclosure, some components of the drawings may be omitted, enlarged or reduced, and do not represent the size of an actual product.
In the description of the present invention, it should be further noted that, unless otherwise explicitly stated or limited, the terms "disposed" and "connected" are to be interpreted broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.
Examples
Referring to fig. 1-2, an irrigation joint for a three-way catheter comprises a joint body 1, wherein the joint body 1 is provided with a first joint 2 for detachably connecting a soft valve of the three-way catheter and a second joint 3 for detachably connecting a syringe.
The outer diameter of the first connecting head 2 is 0.3-0.5cm, and the length is 2-3 cm; in this embodiment, the first connector 2 has an outer diameter of 0.4cm and a length of 2.5 cm.
