Problems solved by technology

[0002] Y-shaped drainage catheters are also commonly used in some special occasions, such as thyroid surgery and uterine surgery, which use Y-shaped bilateral drainage catheters. Most of the front ends of Y-shaped drainage catheters in the prior art use end holes Or the side wall porous tube, its flow rate is limited by the area of ​​the tube hole, and it is easy to block, so it needs to be improved

Embodiment 2

[0029] Embodiment two: see Figure 7 , Embodiment 2 is basically the same as Embodiment 1, and the similarities will not be repeated. The difference is that the strip-shaped notch in Embodiment 2 extends helically around the axis of the pipe.

Embodiment 3

[0030] Embodiment three: see Figure 8-13 , a large flow anti-blocking Y-shaped drainage catheter in the figure, the catheter is approximately "Y"-shaped, including two grooved pipe sections, a closed pipe section, and a tee connecting the grooved pipe section and the closed pipe, characterized in that: the The inside of the grooved pipe section is a radial support body, and the support body divides the grooved pipe section into N drainage channels whose cross section is a fan-shaped area, and the outer wall of the grooved pipe section is provided with N strip-shaped notches corresponding to the fan-shaped area as drainage ports; N ribs protruding toward the axis are arranged inside the closed pipe section, N=4. The included angles between the two joints of the connecting groove pipe sections are both 145°. The strip-shaped notch extends helically around the axis of the pipe. A central pipe is provided on the inner edge of the grooved pipe section along the center of the sup...

Embodiment 4

[0031] Embodiment four: see Figure 14 , Embodiment 4 is basically the same as Embodiment 3, and the similarities will not be repeated. The difference is that the strip-shaped notch in Embodiment 4 extends helically around the axis of the pipe.

Abstract

The invention relates to a high-flow anti-blocking Y-shaped drainage guide pipe. The guide pipe is in a shape similar to Y shape, and comprises two groove pipe sections, a sealed pipe section and a tee, wherein the tee is connected with the groove pipe sections and the sealed pipe section. The guide pipe is characterized in that the interior of each groove pipe section is provided with support bodies which are arranged in a radial form, each groove pipe section is divided into N drainage passages by the support bodies, the cross section of each drainage passage is a fan area, the outer wall of each groove pipe section is provided with N strip groove ports used as drainage ports corresponding to the fan areas, the interior of the sealed pipe section is provided with N ribs, the axial center of each rib is convex, and N is greater than or equal to 3. The high-flow anti-blocking Y-shaped drainage guide pipe has the advantages that the flow quantity is high; the sealed pipe section is provided with the ribs, and after the sealed pipe section is bent, the flow through capability is also realized, and the anti-blocking performance is high; the strip groove ports are used as the drainage ports, so the flow through capability is high, and especially for helical strip groove ports, the flow through capability is higher; by additionally arranging a center pipe, a flushing hole and a flushing liquid supply pipe, the flushing capability is realized, and the groove pipe can be applied to the occasions requiring flushing and drainage.

Description

technical field [0001] The invention relates to the technical field of medical catheters, in particular to a large-flow anti-blocking Y-shaped drainage catheter. Background technique [0002] Y-shaped drainage catheters are also commonly used in some special occasions, such as thyroid surgery and uterine surgery, which use Y-shaped bilateral drainage catheters. Most of the front ends of Y-shaped drainage catheters in the prior art use end holes Or the side wall porous tube, its flow rate is limited by the area of ​​the tube hole, and it is easy to block in addition, so it needs to be improved. Contents of the invention [0003] The object of the present invention is to solve the above problems and provide a large-flow anti-blocking Y-shaped drainage catheter. [0004] The technical solution of the present invention is: a large-flow anti-blocking Y-shaped drainage catheter, which is approximately "Y"-shaped, including two grooved pipe sections, a closed pipe section, a...
