Description

A drainage bag convenient for collecting drainage fluid specimens

Technical Field

The utility model relates to the field of medical instruments, in particular to a drainage bag which is convenient for retaining drainage fluid specimens.

Background Art

At present, most drainage bags used in clinical practice are single-outlet drainage bags, and the outlet tube at the outlet is mostly equipped with a plug-in valve body or a left-right push-to-pull drainage bag outlet valve. However, when taking drainage fluid specimens, the outlet diameter of the plug-in valve body is larger than the diameter of the test tube for taking specimens, so it is difficult to fix the outlet when taking specimens, which can easily lead to drainage fluid outflow and pollute the environment, and cannot guarantee a sterile environment during specimen collection; although the outlet diameter of the drainage bag of the left-right push-to-pull drainage fluid outlet valve matches the diameter of the test tube for taking specimens, the valve of the push-to-pull outlet valve is difficult to control the flow rate, and the outlet is directly exposed to the outside, so it cannot guarantee a sterile environment during specimen collection, and there will be a problem of drainage fluid overflowing from the test tube during the collection process, causing environmental pollution.

In addition, currently, blood collection tubes or culture bottles used to collect blood samples are used clinically to collect drainage fluid for testing of corresponding items. However, the outlet of the existing drainage bag cannot be matched and connected to the blood collection tube. In actual operation, the opening of the blood collection tube needs to be opened to add the drainage fluid into the blood collection tube. However, this not only destroys the negative pressure environment inside the blood collection tube and increases the workload, but also because the blood collection tube is pre-installed with reagents, it may affect the reagents and ultimately affect the test results of the drainage fluid.

In addition, there is no hook on the existing drainage bag. When the patient gets out of bed, he needs to use a pin to fix the drainage bag on his clothes. When returning to bed, he may forget to take off the pin, which increases the risk of stabbing the patient.

It can be seen that the existing drainage bags still have inconveniences and defects in structure, method and use, and are in urgent need of further improvement. How to create a new drainage bag that is convenient for collecting drainage fluid specimens, so that it can simply and conveniently collect drainage fluid in the blood collection tube by improving the bottom structure of the drainage fluid collection tube, which is convenient and practical, greatly reduces the workload of medical staff, and can also facilitate patients to move around through hidden hooks, has become a goal that the industry urgently needs to improve.
