Further, the catheter connecting end comprises a connecting pipe and a fixing ring sleeved outside the connecting pipe, the first pipe cavity is arranged inside the connecting pipe, at least one notch penetrating to the tail end is formed in the pipe wall of the connecting pipe close to the tail end, and the notch penetrates through the side wall.

Furthermore, the fixing ring sleeved outside the connecting pipe can move according to clinical requirements, and the movement of the fixing ring can realize the connection and the separation of the multifunctional joint and the catheter.

Further, the first port is a 6% (luer) internal conical connector made of a semi-rigid material, the 6% (luer) internal conical connector being typically one equipped with external threads and lugs.

Furthermore, a boss is arranged in the first tube cavity, so that the catheter is positioned, and the catheter is prevented from being inserted into the tube cavity too deeply.

The multifunctional joint provided by the utility model has a simple and compact structure, and can realize the communication between the catheter and the connecting pipes on different types of medical instruments.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail below with reference to the accompanying drawings and embodiments. Preferred embodiments of the present invention are shown in the drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model.

As shown in fig. 1 and 2, a first embodiment of the present invention provides a multifunctional connector 100 for connecting a catheter 200 to a connection tube of a medical device.

The multifunctional connector 100 comprises a catheter connecting end 110 and a connector end 120, wherein the catheter connecting end 110 is used for connecting a catheter 200 and is provided with a first lumen 111 therein; the interface end 120 has a second lumen 121 therein, which is communicated with the first lumen 111, and includes a first interface 122 and a second interface 123, the second lumen 121 is located inside the first interface, the second interface 123 is annularly arranged outside the first interface 122, the first interface 122 is a typical 6% (luer) inner conical joint, and the second interface 123 is a 15mm outer conical joint.

The present embodiment provides a multi-functional connector 100 that includes two integrated interfaces at the interface end 120, so that the connection between the catheter 200 and medical devices of different specifications can be realized.

In this embodiment, the connection tube of the medical device may be inserted into the first interface 122 to communicate with the catheter 200, for example, an injection connector is directly connected to the first interface 122 to inject medicine into the catheter 200; the connection with the catheter can also be realized by inserting a connecting pipe on the medical instrument into the closed groove between the first interface 122 and the second interface 123; connecting pipes such as breathing pipelines and breathing airbags on the medical apparatus can be sleeved on the outer wall of the second interface 123, so that the connecting pipes can be communicated with the catheter.

Further, referring to fig. 5, the catheter connection end 110 includes a connection tube 112 and a fixing ring 113 sleeved outside the connection tube 112, the first lumen 111 is disposed inside the connection tube 112, at least one slot 112a penetrating to a terminal end is disposed on a tube wall of the connection tube 112 near the terminal end, and the slot 112a penetrates through a side wall.

Before the catheter is inserted, the fixing ring 113 is sleeved at one end of the connecting pipe 112 close to the joint end, after the catheter 200 is inserted into the connecting pipe 112, the fixing ring 113 is moved towards the tail end, and the fixing ring 113 compresses the pipe wall of the connecting pipe 112 and shrinks towards the inside of the open groove 112a, so that the catheter 200 is fixed.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
