Description

A kind of anti-reflux drainage bag that is convenient for specimen collection

Technical field

The utility model relates to the technical field of medical devices, in particular to an anti-reflux drainage bag that facilitates specimen collection.

Background technique

Inpatients need to have indwelling urinary catheters or drainage tubes due to surgery or disease, and the drainage bag plays the role of collecting urine or drainage fluid. The amount of drainage fluid and urine is an important reference indicator reflecting the condition, and needs to be accurately recorded during the nursing observation process. During the process of placing an indwelling urinary catheter or drainage tube, the drainage bag may be higher than the drainage opening and reflux may occur, which may easily cause retrograde infection. The anti-reflux device of the drainage bag can effectively prevent reflux. In addition, the examination and bacterial culture of urine and drainage fluid play a guiding role in clinical diagnosis and treatment.

In clinical practice, nurses or doctors need to collect urine samples or drainage fluid samples from patients from time to time for testing to assist in judging the condition. Clinical drainage devices generally use a method of clamping the tube, detaching the drainage tube and drainage bag after disinfection, and connecting the syringe to collect the specimen. However, this method is complicated to operate, and the obtained specimen is easy to receive. pollute. Sometimes specimens are extracted by puncturing a drainage tube, but this method is prone to leakage from the drainage tube and needle stick injuries during the operation.

Furthermore, the top of the urine bag is also provided with a hanging ring, and the urine bag is also provided with hanging holes on both sides of the one-way valve.

Further, the surface of the urine bag is provided with scale lines.

Further, the main drainage tube includes a main pipe, and two branch pipes are provided at the bottom of the main pipe. One of the branch pipes is connected to a one-way valve and has a main pipe flow-stop clamp on its surface, and the other branch pipe is connected to the specimen urine bag. connect.

Further, the specimen urine bag includes a side drainage tube connected to a branch tube, a specimen collection bag is provided at the bottom of the side drainage tube, and a liquid extraction port is provided at the bottom of the specimen collection bag.

Further, the side drainage tube is provided with a side flow stop clip.

Compared with the existing technology, the present utility model has the following beneficial effects: Based on the actual clinical needs, the new utility model branches a side tube on the drainage tube to connect the specimen collection bag and the liquid inlet on the basis of the commonly used urine bag, and is simple and easy to make. implementation. Medical staff can use this new product to collect accurate specimens, especially bacterial culture specimens, and can perform aseptic operations. The quality of the specimens is guaranteed and delays in accurately reflecting the condition due to contamination during the specimen collection process are avoided. Diagnosis and treatment judgment.

Detailed ways

The utility model will now be described in further detail with reference to the accompanying drawings. The accompanying drawing is a simplified schematic diagram, which only illustrates the basic structure of the present utility model in a schematic manner, so it only shows the components related to the present utility model.

Please refer to Figure 1-2. An anti-reflux drainage bag that is convenient for specimen collection includes a urethral connector 1 and a urine bag 6. A one-way valve 5 is provided on the top of the urine bag 6, and a main main valve is provided on the top of the one-way valve 5. Drainage tube 2, the urethral connector 1 is located at the top of the main drainage tube 2, a specimen urine bag is also provided on the main drainage tube 2, and a drainage tube 9 is arranged at the bottom of the urine bag 6. The drainage tube 9 is provided with a drain valve 8. The urethral connector 1 is connected to the pipeline on the patient and is used to receive urine. The urine will enter the urine bag 6 or the specimen urine bag along the urethral connector 1 and the main drainage tube 2. The one-way valve 5 can prevent the urine from flowing back and forth to avoid cause infection. After opening the drain valve 8, the urine in the urine bag 6 can be drained through the drain pipe 9. The urine bag 6 is made of transparent plastic material.

The top of the urine bag 6 is also provided with a hanging ring 4, and the urine bag 6 is also provided with hanging holes 14 on both sides of the one-way valve 5. The surface of the urine bag 6 is provided with scale lines 7 . Both the hanging ring 4 and the hanging hole 14 are convenient for hanging the urine bag 6 . Scale line 7 allows you to visually see the approximate volume of urine.

The main drainage pipe 2 includes a main pipe 21. The bottom of the main pipe 21 is provided with two branch pipes 22. One of the branch pipes 22 is connected to the one-way valve 5 and has a main pipe flow stopper 3 on its surface. 22 is connected to the specimen urine bag. There are two branch tubes 22 at the bottom of the main drainage tube 2, which are respectively connected to the urine bag 6 and the specimen urine bag. Normally, the main flow stopper 3 is opened, the specimen urine bag is closed, and the urine directly enters the urine bag 6.

The specimen urine bag includes a side drainage tube 10 connected to a branch tube 22. A specimen collection bag 12 is provided at the bottom of the side drainage tube 10, and a liquid extraction port 13 is provided at the bottom of the specimen collection bag 12.
