Description

Technical Field

[0001] The utility model relates to the field of medical instruments, in particular to a peritoneal drainage tube with a speed regulator. Background Art

[0002] The peritoneal drainage tube is used to drain the fluid accumulated in the peritoneal cavity. The existing drainage tube is equipped with a closing and opening clip, which is used to replace the drainage bag. However, during the drainage process, when the patient has a lot of fluid accumulated in the peritoneal cavity, the fluid needs to be drained out quickly in a short time. When the patient has a less amount of fluid accumulated in the peritoneal cavity, it needs to be drained out more slowly than when there is a lot of fluid accumulated. The speed of fluid drainage is controlled to ensure the content of fluid accumulated in the peritoneal cavity and the normal air pressure in the peritoneal cavity. Utility Model Content

The same figure numbers in the drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the drawings, the drawings do not have to be drawn to scale unless otherwise specified.

[0021] The word “exemplary” is used exclusively herein to mean “serving as an example, example, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

[0022] In addition, in order to better illustrate the present disclosure, numerous specific details are given in the following specific embodiments. It should be understood by those skilled in the art that the present disclosure can also be implemented without certain specific details. In some examples, methods, means, components and circuits well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present disclosure.

[0023] like Figure 1-Figure 8 As shown, a peritoneal drainage tube with a speed regulator comprises a drainage tube 3, a first part 1 and a second part 2; the first part 1 is provided with a tapered through hole 101, and its outer wall is provided with an external thread 102; the second part 2 comprises an outer shell 201 and a tapered platform 202, the tapered platform 202 is arranged in the outer shell 201, the tapered platform 202 and the outer shell 201 are an integral structure, the outer wall of the tapered platform 202 and the inner wall of the outer shell 201 form an inner cavity 203, the inner wall of the outer shell 201 is provided with an internal thread 210, the tapered platform 202 is matched in size with the tapered through hole 101 on the first part 1, the first part 1 and the second part 2 cooperate with the external thread 102 and the internal thread 210 to form a speed regulator, and the speed regulator is arranged on the drainage tube 2.

[0024] The conical platform 202 is provided with a through hole 204, and the side wall of the conical platform 202 is provided with a notch 205, the notch 205 is communicated with the through hole 204, the notch 205 is provided with an umbrella-shaped piece 207, and springs 206 are provided on both sides of the umbrella-shaped piece 207, and the other end of the spring 206 is fixed to the inner wall of the notch 205.

[0025] The springs 206 arranged on both sides of the umbrella-shaped member 207 play the role of restoring the position of the umbrella-shaped member 207. After the umbrella-shaped member 207 is squeezed by the inner wall of the tapered through hole 101 No. 1 and moves toward the through hole 204, multiple umbrella-shaped members 207 squeeze the drainage tube 3 in multiple directions to reduce the inner cavity size of the drainage tube 3 at this end, thereby achieving drainage speed.

[0026] The umbrella-shaped member 207 is provided with a protrusion 209, and the protrusion 209 cooperates with the long guide groove 208 in the notch 205. The long guide groove 208 cooperates with the protrusion 209 to limit the movement of the umbrella-shaped member 207 on both sides.

[0027] When in use, rotate part No. 2 to the lower end of part No. 1 1, pass the drainage tube 1 through the tapered through hole 101 of part No. 1, and out from the through hole 204 at the lower end of part No. 2. When part No. 2 2 is rotated toward the upper end of part No. 1 1, the inner wall of the tapered through hole 101 of part No. 1 1 squeezes and pushes the umbrella-shaped part 207 toward the through hole 204. At this time, the spring 206 is stretched, and multiple umbrella-shaped parts 207 gradually squeeze the drainage tube to slow down the drainage speed of the drainage tube. When part No. 2 2 rotates toward the lower end of part No. 1 1, the umbrella-shaped part 207 rebounds through the spring 206, and the outer wall of part No. 1 1 cancels the restriction on the umbrella-shaped part 207 as it rotates. The spring 206 pulls the umbrella-shaped part 207 back, reduces the squeezing degree of the drainage tube 3, and increases the drainage speed of the drainage tube 3. The speed regulator composed of part No. 1 and part No. 2 controls the drainage speed of the drainage tube 3.

[0028] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
