Infusion apparatus with regulation and control function

Abstract

The invention belongs to the technical field of infusion apparatuses, and discloses an infusion apparatus with a regulation and control function. According to the scheme, the flow rate of liquid medicine can be controlled through a magnetic field of an electromagnet, an inner regulation and control ball in an elastic drip cup triggers an expansion phenomenon after sensing magnetic attraction force in an open state of the electromagnet, so that the passing space of the liquid medicine is reduced, deceleration of the liquid medicine is achieved, and the speed reduction degree is adjusted by controlling the magnetic attraction force; in the opening and closing switching state of the electromagnet, the inner regulation and control ball expands when the electromagnet is opened, and the transition microsphere reforms when the electromagnet is closed, so that repeated extrusion action on the liquid medicine in the elastic drip cup is formed and the flowing speed of the liquid medicine is increased; and meanwhile, local multi-point extension action can be generated while the inner regulation and control ball is integrally expanded, so that bubbles which are possibly mixed in are eliminated, gas is forced to escape out of the liquid medicine and is not prone to entering a human body along with the liquid medicine to harm health, and therefore, the application range of the infusion apparatus is widened and the safety of the infusion apparatus is improved.

Description

Technical field [0001] The present application relates to the field of infusion and, more particularly, relates to an infusion device having a regulatory function. Background technique [0002] Infusion is a common medical supplies, through aseptic processing, and establishing a tunnel between the intravenous liquid for intravenous infusion. Usually the needle or venous needle from the needle shield, an infusion tube, liquid filter, flow regulators, drip chamber, Spikes eight parts, and the like connected to form air filters, as well as part of the infusion device for injection , dosing mouth and so on. [0003] However, the conventional single function infusion, typically only has a simple function of speed, and deceleration can not satisfy a variety of applications, it is difficult to be rapidly absorbed on the one hand a lower liquid temperature, on the other hand Once the liquid-containing gas, after entering the human body having a greater risk. Inventive content [0004] I...

Problems solved by technology

[0003] However, the existing infusion sets have a single function, generally only have a simple speed regulation function, and can only slow down, which cannot meet various application conditions. On the one hand, it is difficult for the liquid to be quickly absorbed by the human body when the temperature is low. Once the liquid contains gas, it will be more dangerous after being injected into the human body
