Heatable and exhaustable precision filter infusion set without phthalate stop liquid

Abstract

The invention provides a heatable venting non-phthalate liquid-check precision filter infusion apparatus, characterized in that a PTC (positive temperature coefficient) ceramic heater is fitted in a dropper, the lower portion of the dropper is provided with a liquid-check precision liquid medicine filter membrane, the lower end of the dropper is provided with a dropper lower cover, a liquid outlet of the dropper lower cover is connected with a line, the line is connected to an external conical connector, the external conical connector is provided with an external conical connector protecting sleeve, and the line is fitted with a flow regulator. The PTC ceramic heater is used to directly heat liquid medicine in the dropper, a special temperature control system is not required, the size is small, bubbles may be intercepted by the liquid-check precision liquid medicine filter membrane after heating; the apparatus has the advantages that filtering speed is high, heating speed is high, air can be evacuated, precise control of infusion rate is unaffected, and blood coagulating can be avoided.

Description

technical field [0001] The invention relates to an infusion set, in particular to an infusion set capable of heating, automatic exhaust, automatic liquid stop, precise filtration of liquid medicine and no harm to the human body, belonging to the field of medical equipment. Background technique [0002] At present, a disposable infusion set is a necessary medical device for clinical infusion, which generally includes a puncture device, an infusion tube, a drip tube, a flow rate regulator, a Luer connector, and an infusion needle from top to bottom. Although the structure of this infusion set is simple, if the infusion needle is not pulled out in time or the bottle is changed in time when the infusion is completed, air will enter the infusion line to form air bubbles, and the air bubbles will cause venous return when the air bubbles enter the patient's body, and even lead to severe medical malpractice. This requires medical staff to run and observe repeatedly, which virtually...

AI Technical Summary

Problems solved by technology

[0005] Due to the low temperature of the liquid medicine in the infusion set, the human body will feel uncomfortable due to the cold liquid medicine during the infusion process, especially in the cold winter, and some medicine liquids drop faster, and the patient will feel uncomfortable. Severe discomfort is not conducive to the body's absorption of the liquid medicine, which affects the effect of infusion therapy

Existing infusion sets are generally heated by means of an external heating jacket. This heating method has a slow heating speed, and the bubbles generated during the heating process cannot be eliminated, and the infusion sets are large in size and bloated.
