Automatic intestinal drug delivery apparatus with heating function

Abstract

The invention provides an automatic intestinal drug delivery apparatus with a heating function which is capable of realizing automated administration in the intestinal tract. The automatic intestinaldrug delivery apparatus with the heating function have separated gas path and liquid path. Working pressure is monitored by a pressure sensor so as to achieve real-time dynamic adjustment on air output of an air pump, thereby ensuring stable pressure in a liquid storage bottle so as to allow stable liquid flow rate; so that, drug liquid reach lesions at constant pressure. One-way valves and a pinch valve are arranged so as to prevent contamination in pipelines caused by liquid reflux; power-on and power-off of a solenoid valve is controlled by a controller so as to realize air intake, liquid intake, intermittent liquid intake and air intake as well as waste discharge, thereby facilitating diagnosis and treatment; a temperature sensor is used for monitoring temperature so as to adjust heating temperature of a heating device, thereby having liquid passing through the heating device heated by heat transfer so as to improve human comfort; and negative pressure is formed in a waste liquid bottle when the air pump is in operation so as to allow flowing of waste liquid into the waste liquid bottle, thereby realizing cleaning of waste liquid so as to reduce probability of infection.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an intestinal automatic drug delivery device with a heating function. Background technique [0002] Enteral administration is an important third way of administration besides oral administration and injection. One of the existing enteral administration methods is through a hanging enema bag, and the other is through a syringe. The hanging enema bag relies on natural gravity , the syringe relies on manual propulsion. On the one hand, due to the unstable and unsustainable pressure of these two methods of administration, the liquid medicine can only reach the rectum, at most the junction of the rectum and the sigmoid colon, and cannot reach deeper parts, such as the transverse colon, let alone the Speaking of the ileocecal part, it runs through the entire large intestine. At the same time, the medicinal liquid cannot be heated and kept warm, which can easily cause discomfor...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the deficiencies of the prior art, the object of the present invention is to provide an intestinal automatic drug delivery device with a heating function, which solves the problem that the pressure of the existing intestinal drug delivery method is unstable and unsustainable, and the drug solution can only reach the rectum. , at most reach the junction of the rectum and the sigmoid colon, and cannot reach deeper parts, such as the transverse colon, not to mention the ileocecal part, which runs through the entire large intestine and cannot heat and keep the liquid medicine, which can easily cause discomfort to the human body
