Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a two-way pressurized gastric lavage device for the department of gastroenterology. Background Technique

[0002] Gastric lavage refers to pouring a certain component of liquid into the gastric cavity, mixing the gastric contents and then pumping them out, repeating this process multiple times. Its purpose is to remove the undigested poisons in the stomach or clean the gastric cavity. For acute poisoning such as swallowing organophosphorus, inorganic phosphorus, alkaloids, barbiturates and other drugs in a short time, gastric lavage is an important rescue measure. Precautions for gastric lavage include patient assessment, protecting the respiratory tract, correctly placing the gastric tube, gentle operation, using appropriate liquid, etc.

[0003] Existing gastric lavage devices generally adopt the method of negative pressure to extract gastric juice and pressurize to inject medicinal liquid to transport the gastric fluid and cleaning agent respectively. However, when injecting the medicinal liquid, the injected medicinal liquid is generally at room temperature, which is likely to cause physical discomfort to the patient when suddenly injected into the stomach. Repeatedly washing the stomach makes the patient's treatment experience extremely poor. The extracted gastric juice directly injected into the waste liquid bucket will emit a large amount of peculiar smell and is also prone to breeding bacteria. Moreover, the connected gastric tubes are directly exposed outside, and the too-long gastric tubes are easy to be entangled with other objects or trip others. Summary of the Invention

[0035] Working principle: Add the medicinal liquid into the inner barrel 604, then start the heating plate 603 to heat up the medicinal liquid. Then, after cleaning the gastric tube 12 to an appropriate length, insert one end into the patient's stomach. The excessive part is spirally wound around the support column 10 and clamped by the snap ring 11. Then start the vacuum pump 705 and open the injection tube 703 to form a negative pressure in the gastric juice bucket 701. The gastric juice in the patient's body is pumped into the gastric juice bucket 701 through the gastric tube 12. Start the water pump 710 to spray the disinfectant liquid in the disinfection box 709 into the gastric juice bucket 701 through the spray head 712. After pumping for a period of time, close the vacuum pump 705 and the injection tube 703, open the infusion pump 608 and the output tube 609, and pump the medicinal liquid in the inner barrel 604 through the gastric tube 12 and inject it into the patient's stomach again. After a period of time, pump the gastric juice again. Repeat this process many times to complete gastric lavage.
