Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, specifically to a collection bag with a drainage tube. Background Technology
[0002] Postoperative drainage of the abdominal cavity is a crucial step in preventing infection and promoting healing. Traditional drainage devices usually consist of a combination of an ostomy bag and a drainage tube. However, traditional ostomy bags rely solely on the opening to collect peritoneal effusion. When the patient moves, peritoneal effusion leaks along the outer wall of the drainage tube to the outside of the ostomy bag, contaminating clothing and increasing the risk of infection. A new type of collection bag with a drainage tube is now used, which can actively drain peritoneal effusion and is less prone to leakage. Utility Model Content
[0003] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.
[0004] To address the technical problems mentioned in the background section, some embodiments of this application provide a collection bag with a drainage tube, comprising:
[0005] The bag has a crescent-shaped structure with a circular connecting part at the opening, and a medical adhesive layer is applied to the outside of the circular connecting part;
[0006] The hose comprises a flexible conical head, a corrugated section, a middle section, and a tail section connected in sequence.
[0007] The elastic conical head is a tapered cone with a hollow elastic rubber ring surrounding the outer wall and multiple axial grooves at the small diameter end.
[0008] The middle section is provided with an oblique hole, and the tail section is provided with an internal thread. The oblique hole is located in the bottom area of the bag body.
[0009] Specifically, the small diameter end of the elastic conical head is 2-5mm.
[0010] Specifically, the corrugated pipe section is a telescopic structure.
[0011] Specifically, the opening diameter of the bag is larger than the outer diameter of the abdominal drainage tube.
[0012] Specifically, the opening direction of the oblique hole forms an angle of 30°-60° with the axial direction of the hose, and the hole diameter is 1-3mm.
[0013] Specifically, the hose has an overall arc-shaped structure.
[0014] The beneficial effects of this utility model are:
[0015] In use, first connect the tubing to the abdominal drainage tube. Insert the abdominal drainage tube into the flexible conical tip. The flexible conical tip can be made of medical-grade silicone, TPU, or other materials. It deforms under the pressure of the abdominal drainage tube, allowing it to connect with abdominal drainage tubes of different diameters. A hollow elastic rubber ring is located on the conical outer wall, providing better extensibility and elasticity, ensuring a tighter connection between the abdominal drainage tube and the tubing. The flexible conical tip also acts as a guide, facilitating the insertion of the abdominal drainage tube into the tubing head. It also prevents the abdominal drainage tube from detaching from the tubing head. Multiple axial grooves are located at the small-diameter end of the flexible conical tip, allowing the small-diameter section to easily deform and disperse, reducing the risk of the abdominal drainage tube slipping on the tubing. The resistance encountered during connection; the bag is attached to the patient's abdominal wall using a medical adhesive layer. The bag has a crescent-shaped design with the smaller diameter end facing downwards. The tail of the tubing passes through the smaller diameter end of the bag and is connected to the drainage bag via internal threads. Peritoneal effusion flows into the tubing through the peritoneal drainage tube, and then into the drainage bag. Some effusion flows into the bag through the outer wall of the peritoneal drainage tube, and then into the drainage bag through oblique holes. Using a collection bag with the above structure, peritoneal effusion can be actively drained. The peritoneal effusion can be completely collected without leakage, keeping the patient's clothing dry and reducing the chance of infection. The drainage bag can be replaced when it is full, extending the service life of the collection bag. Attached Figure Description

[0029] Reference Figures 1-5 As shown, the liquid collection bag with a drainage tube according to this utility model includes:
[0030] The bag body 1 has a crescent-shaped structure, with a circular connecting part 11 at the opening, and a medical adhesive layer 12 on the outside of the circular connecting part 11;
[0031] The hose 2 includes a resilient conical head 21, a corrugated section 22, a middle section 24 and a tail section 23 connected in sequence;
[0032] The flexible conical head can be made of medical silicone, TPU or other materials, while the middle section 24 and the tail section 23 are made of silicone rubber, which has a certain degree of rigidity.
[0033] The elastic conical head 21 is a tapered cone with a hollow elastic rubber ring 211 surrounding its outer wall and multiple axial grooves 212 opened at the small diameter end.
[0034] The middle section 24 is provided with an oblique hole 231, and the tail section 23 is provided with an internal thread 232. The oblique hole 231 is located in the bottom area of the bag body 1.
[0035] In use, first connect the tubing to the abdominal drainage tube. Insert the abdominal drainage tube into the flexible conical head. The flexible conical head can be made of medical-grade silicone, TPU, or other materials. When squeezed by the abdominal drainage tube, the flexible conical head deforms, allowing connection of abdominal drainage tubes of different diameters. A hollow elastic rubber ring is provided on the conical outer wall, which has better extensibility and elasticity, making the connection between the abdominal drainage tube and the tubing more secure. The flexible conical head also has a guiding function, making it easier for the abdominal drainage tube to be inserted into the head of the tubing. The flexible conical head can also prevent the abdominal drainage tube from falling off the head of the tubing. The small-diameter end of the flexible conical head has multiple axial grooves, which are easily deformed and dispersed, reducing the resistance encountered by the abdominal drainage tube when connected to the tubing. The bag is attached to the patient's abdominal wall using a medical adhesive layer. The bag has a crescent shape with the smaller diameter end facing downwards. The end of the tubing passes through this smaller diameter end and connects to the drainage bag via internal threads. Abdominal effusion flows through the abdominal drainage tube into the tubing, and then into the drainage bag. An oblique hole is located at the connection between the tubing and the bag; some effusion flows through the outer wall of the abdominal drainage tube into the bag, and then into the drainage bag through the oblique hole. Using this collection bag with the above structure allows for active drainage of abdominal effusion, ensuring complete collection without leakage, keeping the patient's clothing dry, reducing the risk of infection, and simply replacing the drainage bag when it is full, thus extending its lifespan.
[0036] Specifically, the small diameter end of the elastic conical head 21 is 2-5 mm.
[0037] Specifically, the corrugated pipe section 22 is a telescopic structure.
[0038] The corrugated tube section has an extension length of 10-20cm, adaptable to abdominal drainage tubes of different lengths. Furthermore, the corrugated tube section automatically fixes itself after extension, maintaining its extended length and curvature, preventing blockage caused by bending at the connection between the flexible tube and the abdominal drainage tube, thus ensuring smooth abdominal drainage.
[0039] Specifically, the opening diameter of the bag 1 is larger than the outer diameter of the abdominal drainage tube.
[0040] The peritoneal effusion flowing out along the outer wall of the abdominal drainage tube enters the bag to prevent it from seeping out and contaminating the patient's clothing.
[0041] Specifically, the opening direction of the oblique hole 231 forms an angle of 30°-60° with the axial direction of the hose 2, and the hole diameter is 1-3mm.
[0042] The angled design of the slanted holes optimizes drainage of exudate and reduces residual peritoneal exudate inside the bag.
[0043] Specifically, the hose 2 has an overall arc-shaped structure.
[0044] The curved structure of the tube can adapt to different patient positions.
[0045] The above description is merely a selection of preferred embodiments of this disclosure and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the utility model involved in the embodiments of this disclosure is not limited to the technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described inventive concept.
