High-molecular PTC heating infusion device

Abstract

The invention discloses a polymer PTC heating infusion set, which comprises an infusion tube; along the infusion tube, a bottle inserting needle, a drip tube, a flow regulator and a constant temperature heating jacket are sequentially arranged from top to bottom; the constant temperature heating jacket includes a heat preservation Layer, heating layer and heat transfer layer, the heat preservation layer, heating layer and heat transfer layer are wrapped on the outer skin of the infusion tube in turn from the outside to the inside; the inside of the heat preservation layer is honeycombed; the constant temperature heating jacket is provided with Electric tentacles. Beneficial effects of the present invention: Since the infusion tube is provided with a constant temperature heating jacket, the medicinal liquid or blood preparation device passing through the infusion tube is firstly heated and then enters the patient's body, ensuring that the infused liquid is close to the body temperature, and completely eliminates Adverse reactions to blood transfusions. At the same time, the constant temperature heating jacket is composed of polymer PTC, and the temperature is stable and easy to control.

Description

technical field [0001] The invention belongs to a medical infusion set, in particular to a constant temperature heating infusion set. Background technique [0002] At present, in the clinical infusion and blood transfusion process in the hospital, it is usually done with an infusion set, but the existing infusion set has no heating function. Since the infused medicinal liquid or blood products are usually preserved in the environment of Bawen, during infusion and blood transfusion, the medicinal liquid or plasma that enters the patient's body is relatively cold and obviously lower than body temperature. Blood transfusion reactions such as convulsions, chills, and fever are more prominent in infants, young children, elderly and infirm patients, and patients requiring short-term large-scale infusion or long-term surgery, and are more prominent in cold seasons. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a heat...
