Embodiment 1

[0023] Disposable three-way drainage bag disclosed in this embodiment, such as figure 1 As shown, the disposable three-way drainage bag is connected with the central venous catheter in the illustration, and the disposable three-way drainage bag includes a drainage nut 2, a medical three-way joint 3 and a drainage bag 4; the drainage nut 2 is movable Socketed on the first joint 31 of the medical three-way joint 3, the first joint 31 is provided with a limiting boss 36 that restricts the drainage nut 2 from falling off, and the outer diameter of the limiting boss 36 is larger than the end of the drainage nut 2 by a The inner diameter of the side allows the drainage nut 2 to slide axially along the first joint 31, but will not fall off the first joint 31. The drainage nut 2 is movable, and the drainage nut 2 is threaded to cooperate with the drainage joint 1 of the central venous catheter , in another technical solution, the drainage nut 2 is threaded to cooperate with the pigtai...

Embodiment 2

[0028] See figure 2 , the disposable three-way drainage bag disclosed in this embodiment is basically the same as the technical solution in Example 1, the only difference is that the medical three-way joint 3 is provided with a rotary valve 35, and the rotary valve 35 is hollow and rotates The bottom of the valve 35 is provided with through holes corresponding to the first joint 31 , the second joint 33 and the third joint 34 . When the second joint is not needed, the rotary valve is rotated 180°, and the through hole corresponding to the second joint position 33 on the rotary valve 35 is rotated to the other side so as to close the passage of the second joint 33 to prevent drainage fluid Outflow through the second joint 33. For ease of use, the rotary valve 35 is provided with pointing arrows corresponding to each through hole. The three pointing arrows can be directly used as the handle of the rotary valve, or the three pointing arrows can be printed or pasted on the handl...

Embodiment 3

[0030] The disposable three-way drainage bag disclosed in this embodiment is basically the same as the technical solution in Example 1, the only difference is that the drainage bag 5 is an anti-reflux drainage bag. The anti-reflux drainage bag has been widely used in the existing medical technology field. In one embodiment, it can be achieved by installing an anti-reflux device on the end of the drainage pipeline connected to the bag body. The anti-reflux device can be made of a material with electrostatic adsorption and plastic recovery force. It can be turned on only when it flows in the forward direction and its positive pressure is greater than the electrostatic adsorption force and the plastic recovery force. In another embodiment, the anti-backflow device can refer to the one-way ball valve structure, and the ball valve spool is fixed at the end of the drainage pipeline to realize one-way drainage. When the drainage fluid is flowing forward, the one-way ball valve is ope...

Abstract

The invention discloses a disposable three-way drainage bag which comprises a drainage nut, a medical three-way joint and a drainage bag. A first joint of the medical three-way joint is movably sleeved with the drainage nut, a limiting boss for limiting disengagement of the drainage nut is arranged at the first joint, the drainage nut is matched with a central venous catheter, a pigtail drainage tube or an external ventricular drainage tube through threads, and on the condition that the drainage nut and the drainage joint are connected together, the first joint is inserted into the drainage joint; the medical three-way joint is further provided with a second joint and a third joint, an isolation nut is arranged on the second joint, and the third joint is connected with the drainage bag through a pipeline. By arranging the medical three-way joint for conversion between the existing drainage bag and the drainage tube, due to the medical three-way joint, a user can achieve lock between the drainage tube and the drainage bag, sufficient drainage is achieved, drainage after catheterization, washing and drug injection are facilitated, reverse flow of drainage liquid is avoided, and infections are effectively avoided.

Description

technical field [0001] The invention relates to the technical field of medical appliances, in particular to a disposable three-way drainage bag. Background technique [0002] Drainage surgery is a treatment method in surgery. It is a technique to divert pus, blood or other liquids accumulated between human tissues or in body cavities outside the body or in visceral cavities, so as to prevent postoperative infection and affect wound healing. Drainage tube is the customary device in the drainage operation, but, in the prior art, because part of the drainage bag and the drainage tube tube adopt two pipelines to connect, often cause the pipeline to fall off because of not firmly inserted, easy to infect. Contents of the invention [0003] The purpose of the present invention is to provide a disposable three-way drainage bag to solve the problem that the drainage bag is easy to fall off in the prior art. [0004] To achieve the above object, the technical solution of the prese...
