A gastric juice drainage collection device with pH detection function

technical field

The utility model relates to the technical field of gastric juice drainage devices, in particular to a gastric juice drainage collection device with a pH detection function.

Background technique

In clinical nursing, the indwelling gastric tube is usually used to insert the gastric tube into the stomach through the nose or mouth, and indwell the gastric tube for the patient. After confirming that the gastric tube is in the stomach, the gastric tube is connected with a disposable negative pressure drainage bag to drain the The purpose of decompression of the stomach and intestines is to flow out the liquid and gas accumulated in the gastrointestinal tract. In the indwelling gastric tube operation, it is necessary to confirm whether the gastric tube is placed in the stomach. The pH test paper is often used to test the liquid extracted from the gastric tube through the feeding device, and the test result is compared with the color paper. If it is acidic, it proves that the gastric tube is in the stomach. In the stomach, the fluid drawn out is gastric juice. There are following problems in the above operation:

1. In the clinical indwelling gastric tube operation, to check whether the gastric tube is placed in the stomach, it is necessary to use a feeding device to withdraw gastric juice to measure pH, which is inconvenient to operate and increases the nursing workload.

2. Commonly used pH test paper can only use the degree of color development to determine the pH value, which is easily affected by the external environment and subjective factors, resulting in inaccurate results.

3. The drainage end interface of the commonly used disposable negative pressure drainage device is not firmly connected with the gastric tube, and the drainage bag is easily separated from the gastric tube under the action of external force, resulting in pollution and increased nursing workload.

4. The currently commonly used gastrointestinal decompression device is used to collect gastric juice samples, which is inconvenient to operate and easily polluted, resulting in inaccurate test results and seriously affecting the judgment of the disease.

5. Commonly used disposable negative pressure drainage bags have a limited capacity. When there is a large amount of gas or liquid generated in the gastrointestinal tract, the drainage bag is easily filled, resulting in a decrease in negative pressure. At this time, it is necessary to extract the drainage fluid or replace the drainage bag according to the situation. It is easy to cause pollution, reduce curative effect, increase nursing workload and increase medical costs.
