Description

Technical Field

[0001] This disclosure belongs to the field of medical consumables, and specifically relates to a novel improved pig-tail drainage tube. Background Art

[0002] Pigtail catheters have been widely used in urological surgeries for the kidney, ureter, and bladder. For patients using internal drainage with pigtail catheters, postoperative management has become more straightforward. Since the catheter is implanted, patients can move early, reducing the risk of infection, significantly decreasing the nursing workload, enabling faster postoperative recovery, and shortening the hospital stay significantly. Currently, the outlet at one end of the pig-tail drainage tube remaining in the chest cavity is too small, and the scattered small round holes at the end remaining in the chest cavity are also relatively small, often leading to tube blockage, which in turn causes patients to require re-catheterization, increasing the physical pain and injury to patients, as well as the economic burden.

[0003] Therefore, it is desired to optimize and improve the existing pig-tail drainage tube to adapt to the dredging of the drainage device during drainage and avoid blockage caused by waste liquid. Utility Model Content

[0004] Aiming at the deficiencies of the prior art, the purpose of this disclosure is to provide a novel improved pig-tail drainage tube, which solves the problem of dredging the drainage device during drainage in the background art and avoiding blockage caused by waste liquid.

[0007] In some disclosures, the drainage tube is a variable-diameter silicone hose, and the diameter decreases from the end close to the catheter to the other end.

[0008] In some disclosures, the catheter is a transparent silicone hose, and scales are provided on the outer walls of both the catheter and the drainage tube.

[0009] In some disclosures, the catheter is an equal-diameter hose, and a speed regulator is wrapped around the outer wall of the catheter, and a groove is provided on one side of the speed regulator.

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present disclosure with reference to the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present disclosure.

[0023] Herein, in combination with Figures 1 to 3 to describe an embodiment of a novel improved pig-tail drainage tube. Specifically, the novel improved pig-tail drainage tube is configured as a split structure, which has structures such as a catheter 1, a drainage tube 101, and a drainage hole 102. It can achieve the effect of dredging the drainage device and avoiding blockage caused by waste liquid. By providing drainage holes with larger openings, it is possible to effectively prevent the drainage holes from being blocked by accumulated liquid during the drainage process, thereby avoiding the blockage of the pipeline caused by the accumulated liquid.

[0024] Please refer to Figures 1 to 3 , a novel improved pig-tail drainage tube, comprising:

[0025] The catheter 1 has a drainage tube 101 connected to one end. The drainage tube 101 can contract around the central axis. Multiple drainage holes 102 are provided on one side of the drainage tube 101, and the drainage holes 102 are rectangular openings.

[0026] The drainage tube 101 is a variable-diameter silicone hose, and its diameter decreases from the end close to the catheter 1 to the other end.

[0027] The drainage holes 102 are provided on one side of the drainage tube 101, and the drainage holes 102 are rectangular holes with a size of 1.5*3. Setting them as larger openings can effectively avoid the blockage of the drainage holes 102 caused by accumulated fluid during drainage.

[0028] The drainage tube 101 is set as a variable-diameter silicone hose. Setting it as variable-diameter can facilitate the entry of its top end into the abdominal cavity for positioning and achieving drainage. During the drainage process, the smaller-diameter part of the variable-diameter drainage tube 101 extends inward along the stoma.

[0029] During drainage, the drainage tube 101 is extended along the stoma into the abdominal cavity. The accumulated fluid in the abdominal cavity enters the drainage tube 101 through the drainage holes 102 and is discharged along the catheter. In some cases, the size and shape of the drainage holes 102 can be appropriately adjusted, and they can be adjusted to round holes or rectangular holes. The adjusted shape can be changed according to the composition of the accumulated fluid. In addition, after the drainage tube 101 extends into the abdominal cavity, the guide wire fixed to its top can be pulled to make it contract around the central axis, so that the accumulated fluid in the abdominal cavity can be quickly discharged along all the drainage holes 102.

[0030] The catheter 1 is a transparent silicone hose, and scales 3 are provided on the outer walls of both the catheter 1 and the drainage tube 101.

[0031] Setting the catheter 1 as a transparent silicone hose can facilitate the real-time observation of the accumulated fluid discharged from the inside of the catheter 1. At the same time, the scale 3 provided on its outer wall can count the mass of the discharged accumulated fluid.

[0032] The catheter 1 is an equal-diameter hose, and a speed regulator 401 is wrapped around the outer wall of the catheter 1. A groove 402 is provided on one side of the speed regulator 401. The radius of the groove 402 contracts from one end to the other end, and a roller 5 is slidably connected inside the groove 402.

[0033] During drainage, medical staff can adjust the drainage speed of the accumulated fluid according to the patient's condition. During the adjustment process, the roller 5 located inside the groove is pushed. Since the radius of the groove 402 contracts from one end to the other end, when the roller 5 rolls from the larger-radius part to the other end, the catheter 1 is squeezed, resulting in a slower flow rate of the passing accumulated fluid. On the contrary, the flow rate increases.

[0034] A puncture device 6 is connected to the lower end of the catheter 1, and the puncture device 6 tapers from the upper end to the lower end.

[0035] The puncture device 6 provided at the lower end of the catheter 1 is used to connect the irrigation bag. After the drainage tube 101 is inserted into the abdominal cavity, the puncture device 6 is inserted into the irrigation bag for collecting the effusion. The puncture device 5 is set to be conical to facilitate the medical staff to quickly insert it and prevent the backflow of the effusion, causing secondary harm to the patient.

[0036] An opening 7 is provided at the end of the drainage tube 101 away from the catheter 1.

[0037] The opening 7 provided at the end of the drainage tube 101 away from the catheter 1 is used for tying with a guide wire. After the drainage tube 101 is inserted into the abdominal cavity, by pulling the guide wire, the drainage tube 101 can contract around the central axis, so that each drainage hole 102 can conduct drainage.

[0038] The following further describes a novel improved pig-tail drainage tube provided by the present utility model in conjunction with the accompanying drawings and embodiments.

[0039] A novel improved pig-tail drainage tube includes: a catheter 1, one end of the catheter 1 is communicated with a drainage tube 101, the drainage tube 101 contracts around the central axis, a plurality of drainage holes 102 are provided on one side of the drainage tube 101, and the drainage holes 102 are rectangular openings.

[0040] The drainage tube 101 is a variable-diameter silicone hose, and the diameter decreases from the end close to the catheter 1 to the other end.

[0041] The catheter 1 is a transparent silicone hose, and scales 3 are provided on the outer walls of both the catheter 1 and the drainage tube 101.

[0042] The catheter 1 is an equal-diameter hose, and a speed regulator 401 is wrapped around the outer wall of the catheter 1. A groove 402 is provided on one side of the speed regulator 401.

[0043] The radius of the groove 402 contracts from one end to the other end, and a roller 5 is slidably connected inside the groove 402.
