Description

Vacuum suction with built-in measuring device

technical field

The utility model relates to a medical device, in particular to a gastric juice suction device.

Background technique

Gastrointestinal negative pressure aspirator is a medical device that uses negative pressure to suck out and collect gastric juice. In the medical process, gastrointestinal negative pressure aspirator is widely used clinically to suck out gastric juice. At the same time, in clinical treatment, in order to determine the patient's condition and provide targeted medication to the patient, it is necessary to measure the amount of gastric juice flowing out of the patient.

At present, the gastric juice is usually sucked out by using a gastrointestinal negative pressure aspirator, and then the sucked gastric juice is poured into a measuring device from the gastrointestinal negative pressure aspirator for measurement. However, the patient's gastric juice contains germs. When the gastric juice is poured out, the gastric juice is easy to splash, and the germs in the gastric juice will also pollute the measuring device and the environment; pouring out the gastric juice before the measurement will also increase the workload of the medical staff. Secondly, the gastric juice that needs to be sucked has an unpleasant smell, and the smell of the gastric juice when the gastric juice is poured out is likely to cause discomfort to the medical staff.

The Chinese patent with the application number CN 201220513056.3 published on March 27, 2013 discloses a dual-purpose device for negative pressure drainage and gastric lavage, including an infusion device, a main body of the gastric lavage drainage device, a latex tube, a switch, and a metering bottle. The main body of the drainage device is in the shape of a telescopic bellows, with a spring inside. The upper and lower parts of the front part are connected to the joints through latex tubes, and the lower part of the rear part is connected to the joints through latex tubes. Three latex tubes communicate with the main body of the gastric lavage drainage device, three latex tubes There are switches on the tubes; the upper front joint is connected to the infusion device, the lower front joint is connected to the gastric tube or drainage tube; the rear joint is connected to the metering bottle; the main body of the gastric lavage drainage device is a cylindrical telescopic bellows shape.

When used as a drainage device, close the upper front switch and the rear switch, turn on the lower front switch, compress the main body of the gastric lavage drainage device to discharge the air, and connect the connector to the drainage tube to start negative pressure drainage. When the gas and liquid are too much or need to be measured, close the switch at the bottom of the front part, open the rear switch, compress the main body of the gastric lavage drainage device, and the drainage liquid will flow into the metering bottle. The metering bottle of this dual-purpose device for negative pressure drainage and gastric lavage is arranged on the lower side of the main body of the gastric lavage drainage device, which takes up a large space. Bottles can interfere with access by healthcare workers. Secondly, because the gastric juice is a viscous liquid, if the suctioned gastric juice enters the main body of the gastric lavage drainage device first, and then puts it into the measuring bottle during measurement, part of the gastric juice will adhere to the inner wall of the gastric lavage drainage device during measurement. And can't enter metering bottle, so the gastric juice amount that metering bottle measures is less than the gastric juice amount of actual suction, this negative pressure drainage, gastric lavage dual-purpose device measure inaccurately. In addition, after a measurement, the gastric juice entering the metering bottle cannot be discharged from the metering bottle, and the measurement cannot be continued when the metering bottle is full.
