Abstract

A bile drainage bag comprises a bag body; the upstream of the bag body is connected with a filter box; the filter box is connected with the bag body through a hose; the hose is provided with a clamp; a filter screen is arranged in the filter box and is used for filtering impurities in the bile flowing through the filter box; a drainage tube connector is formed at the upper end of the filter box; the drainage tube connector is positioned at the upstream of the filter screen; the filter box is also provided with a flushing liquid inlet and a flushing liquid outlet; the wash inlet is located downstream of the screen and the wash outlet is located upstream of the screen. Through the bile drainage bag of this application, after the user closed the drainage tube, only need the clip to close for filter cartridge temporarily breaks off with being connected of bag body, then washes the filter screen through the flush fluid, makes the impurity of attached to on the filter screen be washed out via the flush fluid export, and the filter capacity of filter screen is resumeed, then closes flush fluid entry and flush fluid export, opens the clip, resumes the intercommunication of filter cartridge and bag body, can continue to filter and drainage.

Description

Bile drainage bag

Technical Field

The utility model relates to a medical appliance, in particular to a bile drainage bag.

Background

In the ward treatment and nursing process, bile drained from many obstructive jaundice patients needs to be filtered, and then the filtered bile is drunk through the mouth. The general drainage bag only contains the bile of drainage, needs to pour out the back warp cloth and filter the back and then drink by the patient. CN205586278U proposes a bile filtering device, which can filter bile by arranging a filtering layer in a bag body. However, the filtered impurities can quickly block the filter layer, and the bile filter device needs to be replaced again; frequent replacement of the filter unit is firstly costly and secondly increases the probability of infection for the patient.

SUMMERY OF THE UTILITY MODEL

In view of above-mentioned problem, this application aims at providing a bile drainage bag, and it not only has filtering capability, can filter the impurity in the bile, can also wash the filter screen under the condition of not taking off the drainage bag, can in time resume the filtering capability of filter screen.

The bile drainage bag of the present application, comprising a bag body; the upstream of the bag body is connected with a filter box; the filter box is connected with the bag body through a hose; the hose is provided with a clamp;

a filter screen is arranged in the filter box and is used for filtering impurities in the bile flowing through the filter box; a drainage tube connector is formed at the upper end of the filter box; the drainage tube connector is positioned at the upstream of the filter screen; the filter box is also provided with a flushing liquid inlet and a flushing liquid outlet; the wash inlet is located downstream of the screen and the wash outlet is located upstream of the screen.

Preferably, the filter cassette is formed in a square shape; the filter screen sets up along the diagonal of filter box.

Preferably, the screen is formed in multiple layers.

Preferably, the bag body is provided with a scale.

Through the bile drainage bag of this application, after the user closed the drainage tube, only need the clip to close for filter cartridge temporarily breaks off with being connected of bag body, then washes the filter screen through the flush fluid, makes the impurity of attached to on the filter screen be washed out via the flush fluid export, and the filter capacity of filter screen is resumeed, then closes flush fluid entry and flush fluid export, opens the clip, resumes the intercommunication of filter cartridge and bag body, can continue to filter and drainage.

Detailed Description

Hereinafter, the bile filter device according to the present application will be described in detail with reference to the accompanying drawings.

The bile drainage bag of the present application comprises a bag body 10; a filter cartridge 20 is connected to the upstream of the bag body 10; the filter box 20 is connected with the bag body through a hose; the hose is provided with a clamp 25, and the clamp 25 can be selectively opened or closed, thereby controlling communication and interruption between the filter cassette 20 and the bag body 10.

A screen 24 is provided in the filter cartridge 20, and the screen 24 may be multi-layered for filtering foreign substances in the bile flowing therethrough.

A drainage tube connector 21 is formed at the upper end of the filter cassette 20 to connect with a drainage tube. Drain connector 21 is located upstream of screen 24.

The filter cartridge 20 is further formed with a washing liquid inlet 22 and a washing liquid outlet 23; the flushing-liquid inlet 22 is located downstream of the sieve and the flushing-liquid outlet 23 is located upstream of the sieve. The flushing liquid inlet 22 and the flushing liquid outlet 23 can be closed by caps, and the caps are taken off when in use.

The filter cassette 20 may be formed in a square shape, as shown in fig. 2; the screen 24 is disposed along a diagonal of the filter cartridge 20.

The bag body 10 is provided with graduations to measure the volume of bile in the bag body.

When in use, bile flows into the filter box from the drainage tube, is filtered by the filter screen and then flows into the bag body; if drinking, the water flows into the bowl from the interface at the lower end of the bag body.

When the filter screen loses the filtering function due to the blockage of impurities, firstly closing a switch of the drainage tube (the switch is arranged on the drainage tube) and interrupting the drainage; then the hose is clamped and closed through the clamp, so that the bag body is closed; the caps on the washing fluid inlet and the washing fluid outlet are removed, and washing fluid (generally physiological saline) is injected into the filter box by using a syringe and the like, and the washing fluid is backwashed from the downstream to the upstream of the filter screen and discharged from the washing fluid outlet after being washed away by impurities attached to the filter screen. After the filtering function of filter screen resumes, stop washing, the bonnet on washing liquid entry and the flush fluid export is covered again, opens the clip of clip closed hose, resumes the intercommunication between filter cartridge and the bag body, opens the clip on the drainage tube at last, resumes the drainage.
