Description

Technical Field

[0001] The utility model relates to the technical field of drainage bags, in particular to a drainage bag which is convenient for collecting specimens. Background Art

[0002] Disposable drainage bags are often used clinically to drain urine and postoperative drainage of chest, abdomen, and pelvic organs. At present, disposable drainage bags are used in a relatively simple manner. When it is necessary to sample the liquid in the drainage bag, a hole needs to be pierced in the bag. The drainage fluid is easy to contaminate the hands or other parts of medical staff, resulting in the need for cleaning and environmental pollution. In addition, there may be a large number of pathogens such as bacteria or viruses in the drainage bag. It is necessary to disinfect and sterilize the drainage bag after use in time to avoid leakage of accumulated fluid and threaten the health of medical staff, accompanying personnel or other patients and their families. The existing treatment method generally cuts a corner of the drainage bag and stores it for disinfection. This method is also easy to contaminate the hands or other parts of medical staff, increasing the risk of infection for medical staff and accompanying personnel. Utility Model Content

[0005] A side bag integrally formed with the drainage bag body is provided on one side of the drainage bag body, the side bag is filled with chlorine-containing disinfectant, a barrier film is provided between the drainage bag body and the side bag, the barrier film ruptures under the action of external force to connect the drainage bag body with the side bag.

[0006] Furthermore, an arc-shaped support plate is provided on the top of the drainage bag body, and the drainage tube passes through the through hole in the middle of the arc-shaped support plate and is connected to the drainage bag body. The drainage tube passes through the arc-shaped support plate to provide a certain support effect on the drainage tube, thereby ensuring the stability of the drainage tube connection.

[0007] Furthermore, an exhaust valve is provided at one end above the drainage bag body, and opening the exhaust valve can reduce the pressure and exhaust the drainage bag body.

[0008] Furthermore, the drainage bag body and the specimen bag are both provided with scale lines.

[0009] Furthermore, hanging holes are provided at both ends of the top of the drainage bag body to facilitate the passing of a hook or a hanging rope for fixing.

[0010] Furthermore, the arc-shaped support plate is made of plastic material with a certain hardness.

[0011] Furthermore, the upper part of the specimen bag is threadedly connected to the connecting piece to facilitate the specimen bag to be removed from the connecting piece.

[0012] The above technical solution has the following beneficial effects:

[0013] The utility model realizes convenient and quick sampling by arranging a specimen bag at the bottom of the drainage bag body, without piercing a hole in the drainage bag body. In addition, after the drainage bag body is used, the barrier film is broken by pressing the side bag, so that the side bag is connected with the drainage bag body, and the accumulated fluid in the drainage bag body is disinfected. In this process, the medical staff and the patient's accumulated fluid are non-contacted, and the cutting of the drainage bag and the injection of chlorine-containing disinfectant are avoided, which avoids the possibility of pathogens such as bacteria or viruses in the accumulated fluid in the main bag being spread with the air and polluting the environment, thereby improving the safety of use for patients and medical staff.
