Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a pediatric gastric lavage device. Background Technology

[0002] Currently, with the increasingly fast pace of life, many people have irregular eating habits, food hygiene inspections are often inadequate, and many people do not pay attention to food expiration dates, consuming spoiled food. This leads to food poisoning in many people, especially children with weaker immune systems. Gastric lavage is commonly used to treat food poisoning. Gastric lavage involves instilling a specific liquid into the stomach cavity, mixing it with the stomach contents, and then withdrawing it, repeating this process multiple times. Its purpose is to remove unabsorbed toxins or cleanse the stomach cavity; clinically, it is used for preparation before gastric surgery and examinations.

[0003] The pediatric negative pressure gastric lavage device disclosed in CN221692283U has a rubber soft sleeve with a recovery chamber and an lavage chamber inside. The recovery chamber is connected to the waste liquid tank through a connecting hose, while the lavage chamber can be supplied with gastric lavage fluid through a water delivery hose, a water pump, and a water suction pipe. Using the soft sleeve instead of the separate delivery hose and suction hose in the prior art not only facilitates the extraction and circulation of waste fluid during lavage, but also reduces children's pain and prevents them from feeling uncomfortable and developing strong resistance. However, the existing technology still has shortcomings:

[0004] 1. When performing gastric lavage, doctors usually need to mix physiological saline with a certain proportion of drugs. The current technology does not have a stirring device, which is not conducive to the full mixing of drugs. This makes it easy for the drugs to precipitate in the gastric lavage fluid in the reservoir after a period of time, affecting its use. At the same time, there is no heating device in the reservoir to heat and keep the gastric lavage fluid warm. The cold liquid can easily irritate the child's stomach when rinsing.

[0005] 2. Since the tubing needs to be inserted into the child's stomach through the mouth, the existing technology does not have a heating device to heat the flushing tubing assembly. The cool tubing sheath can irritate the child's mouth and esophagus, increasing patient discomfort, thus making it impractical. Utility Model Content

The electric heating layer 14 is activated to heat the outer surface of the flexible tubing 13. After the child patient lies comfortably on the bed, the doctor applies the external... The tubing 13 is inserted into the patient's mouth and esophagus, with the rubber ball 18 positioned in the patient's mouth to prevent the child from struggling and causing the tubing to slip off, and to prevent the child from biting the tubing and causing blockage. The second water pump 17.2 is started to first draw the toxic gastric juice from the patient's stomach through the recovery chamber 17.1 and connecting pipes 17.3 and 17.4 into the waste liquid tank 10. Then, the first water pump 16.2 is started in conjunction with the second connecting pipe 16.4 to draw gastric lavage fluid from the storage tank 4. The liquid enters the cleaning chamber 16.1 through the first connecting pipe 16.3 and then enters the patient's stomach through the cleaning chamber 16.1 for rinsing.
