Description

Gastrointestinal pressure reducer

Technical Field

The utility model relates to the technical field of medical appliances, in particular to a gastrointestinal pressure reducer.

Background

Gastrointestinal decompression is to put a stomach tube into the stomach through the nasal cavity, suck out accumulated air and liquid in the gastrointestinal tract, relieve abdominal distension, reduce bacterial toxin in intestinal cavities and reduce pressure in the gastrointestinal tract, and is an important means for clinically treating gastrointestinal obstruction, retention, paralysis, perforation and acute pancreatitis caused by various reasons. Maintaining a sustained and effective gastrointestinal decompression is a guarantee for disease diagnosis, body recovery, and functional recovery.

The pressure control of the gastrointestinal pressure reducer is a key factor for determining the gastrointestinal pressure reducing effect, and unsuitable suction pressure can not only not achieve the treatment effect, but also have negative influence on the rehabilitation of a patient, the suction force is too large to enable gastric mucosa to be adsorbed in a small hole at the head end of a stomach tube so as to lead to unsmooth drainage or damage local gastric mucosa, and the pressure is too small to suck out the retained contents in the gastrointestinal tract so as to lead to ineffective suction, thereby aggravating nausea, vomiting, abdominal distention and severe complications caused by the operation incision of the patient. The research shows that the negative pressure aspirator has the best gastrointestinal decompression effect on patients when the pressure value is-5 KPa to-7 KPa.

Medical staff puts into the stomach with the drainage tube from patient's nasal cavity when carrying out intestines and stomach decompression, presses the casing of pressure reducer, makes the exhaust hole discharge on the casing of air in the casing, and under negative pressure spring's effect, the casing has the pressure that resets, makes the casing form the negative pressure in. However, when the medical staff presses the housing, the magnitude of the negative pressure which can be generated in the housing is difficult to control due to the influence of factors such as the pressing force and the pressing deformation height, so that the medical staff cannot determine whether the generated negative pressure can be within the required pressure value range, and the problem that the pressure is too small or too large easily occurs.
