Embodiment 1

[0026] A multilumen central venous catheter, such as figure 1 and figure 2 As shown, a first branch conduit 1 is included, a second branch conduit 2 is provided on one side of the first branch conduit 1, a connector 3 is provided at one end of the first branch conduit 1 and the second branch conduit 2, and the first branch conduit 1 and one end of the second branch conduit 2 communicate with the inside of the connector 3, the two sides of the connector 3 are closely bonded with lugs 31, the lugs 31 are provided with a through hole 311, and the front side of the connector 3 is provided with There is a main conduit 4, and one end of the main conduit 4 communicates with the interior of the connector 3, and a plurality of side holes 41 are opened on the peripheral outer wall of the main conduit 4 near the front end.

[0027] Specifically, both the first branch catheter 1 and the second branch catheter 2 communicate with the main catheter 4, which is convenient for drainage and i...

Embodiment 2

[0030] As the second embodiment of the present invention, the difference from Embodiment 1 lies in that the radii of the plurality of side holes 41 are all different.

[0031] What needs to be added is that the multiple side holes 41 with different diameters are more conducive to infusion and drainage, and reduce the occurrence of pipeline blockage.

Embodiment 3

[0033] As a third embodiment of the present invention, in order to facilitate fixing the connector 3, the inventor has provided a fixer 5, such as Figure 3 to Figure 5 As shown, a fixer 5 is provided below the connector 3, and two symmetrical sleeves 51 are closely bonded to the top surface of the fixer 5. A sleeve rod 52 is arranged inside the sleeve sleeve 51, and the top surface of the sleeve rod 52 is Tightly bond the limit ring 54, the periphery of the sleeve rod 52 is provided with a spring 53, the bottom of the spring 53 is tightly bonded to the inner bottom surface of the sleeve 51, the top of the spring 53 is closely bonded to the bottom surface of the limit ring 54, and the limit The top surface of the ring 54 is tightly bonded with a pressure rod 55, one end of the pressure rod 55 is located in the through hole 311, the bottom surface of the holder 5 is provided with a groove 56, and the groove 56 is embedded with a sponge 57, and the bottom surface of the holder 5 ...

Abstract

The invention relates to the technical field of venous catheters, in particular to a multi-cavity central venous catheter. The multi-cavity central venous catheter comprises a first branch catheter, asecond branch catheter is arranged on one side of the first branch catheter, a connector is arranged at one ends of the first branch catheter and the second branch catheter, and one end of the firstbranch catheter and one end of the second branch catheter are communicated with the inside of the connector. According to the multi-cavity central venous catheter, by arranging a plurality of side holes, occurrence of the blocking condition of the catheters is reduced, workloads of the medical staffs are thus reduced, and the problem that an existing central venous catheter is easy to block is solved; the multi-lumen central venous catheter is provided with a fixing device, breathing and sweat absorption of the skin at the fixed position are facilitated, and occurrence of pressure sores is avoided. The design is humanized, a traditional mode of needlework suture fixation is changed, pains of a patient are reduced, and the problem that the fixing mode of the existing central venous catheteris easy to bring pains to the patient is solved.

Description

technical field [0001] The invention relates to the technical field of venous catheters, in particular to a multi-lumen central venous catheter. Background technique [0002] The central venous catheter is a kind of intravascular tube, which is placed in the large vein or the pericardial cavity. It is often used to measure central venous pressure, fluid infusion, pericardial drainage, etc. On the one hand, when the existing central venous catheter is performing infusion or drainage, Because there are few side holes on the main catheter, catheter blockage often occurs, which brings great troubles to the work of medical staff. On the other hand, when using the existing central venous catheter, medical staff usually use needles and threads Suturing the connector on the patient's skin not only brings pain to the patient, but also easily causes secondary infection. In view of this, we propose a multi-lumen central venous catheter. Contents of the invention [0003] The purpose...
