Description

Drainage bag

Technical Field

The utility model relates to the technical field of medical supplies, in particular to a drainage bag.

Background

The drainage bag generally refers to a transparent plastic bag which is used for specially containing liquid drained out from the drainage tube and is led out from the interior of a body or deep part of an operation after the operation by using a pipeline.

At present, the clinical drainage bag has some defects in the using process: 1. when the proportion of blood in the drainage liquid is high, the junction of the bag body and the drainage tube is easy to agglomerate due to the folding of the bag body, the agglomeration can block the drainage tube to influence the normal operation of drainage, sometimes, the phenomenon of backflow of the drainage liquid can occur, and the secondary infection of the tissues of a patient can be easily caused; 2. the bag body in the prior art is generally in a dry-flat state before being used, and air in the bag body is extruded and exhausted; in order to prevent the bag body from being influenced to collect the drainage liquid, the medical staff is required to manually tear the bag body which is attached together before use. However, because the air in the bag body is completely discharged, when medical personnel pull the bag body from the middle part of the bag body, the cavity generated in the center of the bag body is in a negative pressure state, and the edge bag body is more tightly attracted with each other due to the negative pressure state, so that the difficulty of tearing the bag body is increased, and the operation difficulty of the medical personnel is increased.

SUMMERY OF THE UTILITY MODEL

Aiming at the defects, the technical problems to be solved by the utility model are as follows: provides a drainage bag to effectively avoid the problems of catheter blockage and drainage liquid backflow.

In order to solve the technical problems, the technical scheme of the utility model is as follows:

a drainage bag comprises a bag body, wherein a connecting hose, a communicating pipe and a drainage tube are sequentially arranged above the bag body, a branch pipe is arranged on the communicating pipe, the branch pipe inclines towards the upper end of the communicating pipe, and a buffer bag is arranged on the branch pipe; the lower end of the connecting hose is horn-shaped, and a liquid discharge side groove is formed in the side wall of the lower end of the connecting hose.

Preferably, a through pipe which communicates the inside of the bag body with the outside is arranged below the bag body, a sealing cap is arranged at the lower end of the through pipe, and finger ring buckles which are attached to the bag body are arranged on two sides of the bag body.

Preferably, a hose joint is arranged between the communicating pipe and the connecting hose.

Preferably, the pipe wall of the upper end of the drainage pipe is provided with drainage holes.

Preferably, the connection hose is communicated with the bag body.

Preferably, the bag body is provided with scale marks.

Preferably, the finger ring buckle and the bag body are integrally formed and made of the same material as the bag body.

After the technical scheme is adopted, the utility model has the beneficial effects that:

1. the branched pipe is arranged on the communicating pipe, the branched pipe inclines towards the upper end of the communicating pipe, the branched pipe is provided with the buffer bag, the arrangement of the structure can prevent drainage liquid from flowing backwards in the splitting or combining process of the drainage bag, and the drainage liquid can be prevented from flowing backwards to the drainage tube through the inner space of the buffer bag, so that tissue pollution is prevented;

2. the lower end of the connecting hose is horn-shaped, the side wall of the lower end of the connecting hose is provided with a liquid discharge side groove, and the bag body can not be blocked when being folded to influence the leading-out of drainage liquid.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

In the description of the present invention, it should be understood that the terms "upper end", "lower end", "above" and "below" are based on the positional relationship shown in the drawings, and are only for convenience of describing the technical solution of the present invention and simplifying the description, and thus, should not be construed as limiting the present invention.

As shown in both figures 1 and 2, a drainage bag comprises a bag body 1, a connecting hose 2, a communicating pipe 3 and a drainage tube 4 are sequentially arranged above the bag body 1, a drainage hole 41 is formed on the pipe wall of the upper end of the drainage tube 4, the drainage hole 41 is convenient for leading out liquid in body tissues, a branch pipe 5 is arranged on the communicating pipe 3, the branch pipe 5 inclines towards the upper end of the communicating pipe 3, a buffer bag 6 is arranged on the branch pipe 5, the arrangement of the branch pipe 5 and the buffer bag 6 can prevent the drainage liquid from flowing back in the process of splitting or combining the drainage bag, through the internal space of the buffer bag 6, through the control of the height position between the drainage tube 4 and the connecting hose 2, the drainage liquid in the bag body 1 can be prevented from flowing back to the drainage tube 4 to prevent tissue infection, the buffer bag 6 can temporarily store the liquid flowing out of the drainage tube 4 after the bag body is detached, preventing drainage liquid from flowing out to the external environment; connecting tube 2 and the 1 intercommunication of the bag body, connecting tube 2's lower extreme is the loudspeaker form, the loudspeaker form is by the one end that is close to the bag body 1 to the one end throat gradually of keeping away from the bag body 1, connecting tube 2's lower extreme lateral wall is provided with flowing back side channel 7, after bag body 1 takes place folding back, then great because of loudspeaker form opening, and be provided with flowing back side channel 7 on the lateral wall, drainage liquid can flow into to the bag body 1 by flowing back side channel 7, thereby can avoid the drainage liquid to block up the phenomenon of caking and take place.
