Description

Technical Field

[0001] The utility model relates to the field of medical devices, in particular to a Y-shaped drainage bag. Background Art

[0002] The bleeding and fluid accumulation inside the patient's body or after local surgery need to be led out with a pipe, so a drainage bag is needed. The current structure of the drainage bag is formed by directly connecting the drainage tube and the bag body. The connection port at the upper end of the drainage tube is connected to the patient's body, and the lower end opening is connected to the bag body. Taking patients with indwelling catheterization as an example, in the prior art, when fresh urine specimens need to be retained, the drainage bag needs to be clamped, and a syringe is used to extract urine from the catheter while waiting for urine to be in the bladder. Improper puncture position can easily lead to airbag damage and catheter slippage; if it is extracted from the lower discharge port of the bag body, it is easy to cause inaccurate test results due to the influence of old urine in the bag body. If it is necessary to retain a specimen, it can only be extracted with a syringe when the drainage bag is replaced, and then the surface of the drainage bag is disinfected, which wastes consumables, is more prone to contamination, and is more prone to cross infection, or leads to untimely specimen retention. Utility Model Content

[0003] The utility model aims at the above-mentioned problems, overcomes at least one disadvantage and proposes a Y-shaped drainage bag.

[0004] The technical solution adopted by the utility model is as follows:
