Description

Vomitus collection device convenient to use

Technical Field

The application relates to the technical field of medical auxiliary equipment, in particular to vomitus collection device convenient to use.

Background

Vomiting is caused by the inverse peristalsis of esophagus, stomach or intestinal tract accompanied by strong spastic contraction of abdominal muscles, which forces the contents of esophagus or stomach to flow out of mouth or nasal cavity, and the reasons are:

1. organic obstruction of digestive tract: the contents of the esophagus, stomach or intestine are obstructed from descending and forced to move backwards, causing vomiting. Such as congenital malformations of the digestive tract (occlusion or stenosis at different sites); the older children mostly have acquired intestinal torsion, intussusception and ileus (for example, common ascaris obstruction).

2. Infectious diseases of the digestive tract: enteritis, gastritis and appendicitis can cause reflex vomiting due to the irritation of inflammation to stomach and intestines, and are often accompanied by abdominal pain, nausea, diarrhea and abdominal distension.

3. Abnormal bodily function: in case of systemic infection or metabolic disorder, the symptoms are usually accompanied by fever, anorexia, nausea, abdominal distension, and other toxic symptoms.

4. Cranial nerve system diseases: if intracranial hypertension symptom, meningeal irritation symptom or intracranial space occupying lesion occurs, central jet emesis can be caused, nausea is not caused before emesis, and other nervous symptoms such as headache, somnolence, coma, convulsion and the like are accompanied.

5. Poisoning: the poison stimulates the gastrointestinal tract locally and acts on the central nervous system to cause vomiting.

Patients with emesis were divided into:

1. the mind is clear, and the life can be self-managed;

2. clear mind, weakness and weakness, failing to take care of oneself;
