Description

Negative pressure adjustable, easy-to-use drainage device

technical field

The utility model belongs to the technical field of medical equipment, in particular to a drainage device with adjustable negative pressure and convenient use.

Background technique

Since the organ wounds of many patients have not been healed effectively after surgery, various fluids will accumulate in the abdominal cavity at this time. The most common thing is that in clinical practice, in order to ensure that intestinal patients can recover as soon as possible after surgery, it is necessary to drain the digestive juice with a low pH value from the stomach out of the body with the help of a drainage device. Disposable negative pressure suction bags or mechanical suction devices are usually used in domestic and foreign markets to drain body fluids out of the body. However, the negative pressure generated by this method is not stable, and the suction pressure may change greatly, resulting in unsatisfactory negative pressure suction effect, and even backflow phenomenon, and there is only one drainage bag, and the existing drainage device has a single function , can not cooperate well with the operation and needs to be further improved.

Utility model content

In order to overcome the deficiencies of the above-mentioned prior art, the purpose of this utility model is to provide a drainage device with adjustable negative pressure and easy to use, which can adjust the pressure in the drainage bag according to the actual situation without backflow phenomenon.

In order to achieve the above object, the utility model adopts the following technical solutions:

A drainage device with adjustable negative pressure and easy to use, comprising a first drainage bag with a vacuum inside, the first drainage bag is connected with a drainage tube, the end of the drainage tube is provided with a drainage port, and the first drainage bag The upper part of the bag is provided with an exhaust port, and the bottom of the first drainage bag is provided with an outlet one-way valve, which is characterized in that it also includes a second drainage bag and an anti-sucking tube, the second drainage bag is connected to the drainage tube, And located near the first drainage bag, the inside of the second drainage bag is in a vacuum state, there is a first control valve between the second drainage bag and the drainage tube, and the first drainage bag is provided with As for the anti-suckback tube, one end of the anti-suckback tube passes through the bottom of the first drainage bag and is sealingly connected with the bottom of the first drainage bag, and the other end is located in the first drainage bag and opens downward.

The second drainage bag is connected to the negative pressure connector through a negative pressure tube, and the negative pressure tube is provided with a second control valve.

The anti-suckback pipe is an inverted U-shaped pipe.

The first drainage bag is provided with two longitudinal and arc-shaped pressure seams inwardly from both sides.

The first drainage bag and the second drainage bag are respectively provided with scale marks.

The part of the anti-suckage tube passing through the bottom of the first drainage bag is provided with a sealing plug.

The distance between the opening of the anti-suckback tube located inside the first drainage bag and the bottom of the first drainage tube is 10-25 mm.

The beneficial effects of the utility model are: the second drainage bag is in a vacuum state, and can also be connected with a negative pressure connector, which can not only adjust the negative pressure of the first drainage bag, but also play a role in slowing down the pressure when the pressure is high , when there is a lot of drainage liquid, the second drainage bag can be used as a common drainage bag; the anti-suckback tube prevents the drainage liquid from returning to the human body. The limitation is convenient to better prevent the liquid from sucking back; the first drainage bag is provided with a pressure seam, and the middle of the first drainage bag divides the bag into three equal parts from the longitudinal direction. When the liquid is contained, the liquid can be divided into multiple parts. In this area, there is no phenomenon of liquid sinking and protruding outside, and it is more convenient for patients to carry. The utility model has a simple structure, can effectively prevent sucking back during the operation, and can adjust the negative pressure. The utility model is easy to use and less painful for patients.

Detailed ways

A specific embodiment of the utility model is described below in conjunction with the accompanying drawings.

As shown in Figure 1 and Figure 2, the utility model provides a drainage device with adjustable negative pressure and convenient use, including a first drainage bag 1, the first drainage bag 1 is connected with a drainage tube 2, and the drainage tube 2 The end is provided with a drainage port 3, the upper part of the first drainage bag 1 is provided with an exhaust port 4, and the bottom of the first drainage bag 1 is provided with an outlet check valve 5, which is characterized in that it also includes a second drainage bag 6. Anti-suckback tube 7, the second drainage bag 6 is connected to the drainage tube 2 and is located near the first drainage bag 1, and the second drainage bag 6 and the drainage tube 2 are provided with The first control valve 8, the second drainage bag 6 is connected to the negative pressure connector 10 through the negative pressure tube 9, the second drainage bag 6 is used as a negative pressure supply and adjustment device, and the inside is in a vacuum state, and it also serves as an auxiliary Drainage device, the negative pressure pipe 9 is provided with a second control valve 11, the first drainage bag 1 is provided with an inverted U-shaped pipe as the anti-suction pipe 7, the heights of the two ends of the anti-suction pipe 7 are different, the One end of the anti-suckage tube 7 passes through the bottom of the first drainage bag 1 and is sealedly connected with the bottom of the first drainage bag 1, and the other end is located in the first drainage bag 1 with the opening downward, and is provided with a A sealing plug 12 outside the drainage bag 1 .

The first drainage bag 1 is provided with two longitudinal and arc-shaped pressure seams 13 inwardly from both sides. Divide the middle of the first drainage bag 1 into three equal parts vertically to form a cavity that runs through the top, bottom, left, middle and right, so that when the bag holds the liquid, it can divide the liquid into multiple regions, so that the liquid does not sink and protrude Out of the phenomenon, the patient is more convenient when carrying.

The first drainage bag 1 and the second drainage bag 6 are respectively provided with scale lines 14 .

The distance between the opening of the anti-suckback tube 7 in the first drainage bag 1 and the bottom of the first drainage tube 2 is preferably 10-25 mm.

When in use, the drainage tube 2 is inserted into the surgical site of the human body, and the drainage fluid flows into the first drainage bag 1 along the drainage tube 2. When the negative pressure in the first drainage bag 1 is insufficient, the first control valve 8 is opened to communicate with the second drainage bag 6 , there is a certain negative pressure in the second drainage bag 6, which can prevent sucking back to a certain extent. When the negative pressure of the second drainage bag 6 is low, the second control valve 11 can be opened, and the negative pressure connector 10 can provide negative pressure; Or when the pressure of the first drainage bag 1 is high during the drainage process, the second drainage bag 6 can be used as a pressure relief device; after the first drainage bag 1 is filled with liquid, the second drainage bag 6 can be used as a common drainage bag.
