Description

Technical Field

[0001] The utility model relates to the technical field of anti-theft covers, in particular to an improved negative pressure aspirator. Background Art

[0002] Gastrointestinal decompression is to insert a gastric tube through the oral or nasal cavity and connect it to a disposable negative pressure aspirator. Under the action of negative pressure and siphon principle, the gas and liquid accumulated in the gastrointestinal tract are sucked out to reduce the pressure in the gastrointestinal tract and improve the blood circulation of the gastrointestinal wall.

[0003] The amount of gastrointestinal decompression extraction is related to the amount of gastric contents in the patient's stomach. Generally, it is 50ml in an empty state, and the amount of gastric fluid can reach 1500-2000ml after a meal. After the patient is placed in gastrointestinal decompression, the stimulation of the esophagus by the gastric tube, coupled with the discomfort of the disease itself, causes the patient's pain to deepen. Generally, the negative pressure aspirator after suction is a round cylinder that can hold 1000ml. Since the gastrointestinal decompression device has no support body, the patient can only hold it with one hand when moving, which reduces the comfort. In addition, after the bedridden patient is placed in gastrointestinal decompression, the negative pressure aspirator filled with gastric fluid placed next to the pillow will accidentally fall off when turning over, causing the pipeline to slip, thereby increasing the risk of pipeline slippage. Even if the negative pressure aspirator does not slip off, it can cause discomfort in the patient's nose and esophagus due to the pulling effect. In addition, patients who are usually placed in gastrointestinal decompression need to record the amount of gastric fluid, and each time the gastric fluid is poured out, it needs to be poured into the measuring cup again for measurement, which makes the patient and his family feel cumbersome.

[0004] After following up patients with gastric tube placement, the inventor of this solution found that most patients were anxious about the inability to properly place the negative pressure aspirator. Therefore, it is particularly important to improve a negative pressure aspirator that is convenient for placement and fixation of the negative pressure aspirator. Utility Model Content
