Problems solved by technology

Generally, the normal saline solution used for infusion is stored in dark conditions, which leads to the generally low temperature of the medicinal solution in the infusion bottle.
In the case of summer, the medicinal liquid with lower temperature is not very irritating to the human body, and the patient can accept it; The stimulation is huge, which makes the patient's body unbearable
Under the existing circumstances, it is generally used to heat the position of the insertion pin by using hot water cover or heating stickers, but the operation is very inconvenient, and there are also certain safety hazards

preparation example Construction

[0033] The invention provides a kind of preparation method of the PTC resistance based on polyphenylene sulfide, and this preparation method comprises:

[0034] 1) Soaking strontium carbonate, strontium titanate and yttrium oxide in lye, then filtering and washing the filter cake, and then placing the cleaned filter cake in an amino acid solution for modification to obtain a modified composition ;

[0035] 2) graphene is dispersed in water, then add p-aminobenzenesulfonic acid and vanadium pentoxide (acting as catalyst) to carry out sulfonation reaction to obtain the operation of sulfonated graphene;

[0036] 3) In the presence of protective gas: dissolve polyphenylene sulfide and maleic anhydride grafted polyethylene in an organic solvent, then add the modified composition, sulfonated graphene and carbon nanotubes to the system and perform ultrasonic vibration , and then remove the organic solvent by evaporation to obtain a PTC resistor based on polyphenylene sulfide.

Abstract

The invention discloses a disposable infusion set provided with a constant temperature heater, the disposable infusion set sequentially contains a venous needle, an infusion hose (3) and a bottle stopper puncturer, and the infusion hose (3) is provided with There is the constant temperature heater, and the constant temperature heater includes a bottom box (1) and a top cover matched with the bottom box (1); the bottom box (1) is sequentially provided with a heating chamber and a fixed chamber, the heating chamber is provided with a PTC resistance (4) and the PTC resistance (4) is connected to a power supply for heat generation; the top of the fixed chamber is provided with a positioning piece to fix the infusion hose ( 3); wherein, the Curie temperature of the PTC resistor (4) is 25-40°C. The constant temperature heater can carry out constant temperature heating to the medicinal liquid in the infusion set.

Description

technical field [0001] The invention relates to a medical device, in particular to a disposable infusion set provided with a constant temperature heater. Background technique [0002] Disposable infusion set is a common disposable medical consumable that is mainly used for intravenous infusion after aseptic treatment to establish a channel between the vein and the liquid medicine. It generally consists of an intravenous needle, a protective cap, an infusion hose, It is composed of a filter, a flow rate regulator, a drip pot, a cork piercer, and an air filter connection of the intake pipe. [0003] At present, in the infusion process, the disposable infusion set is generally communicated with the infusion bottle, and then the venous needle is inserted into the meridians of the patient to perform the infusion. Generally, the physiological saline used for infusion is stored under dark conditions, which leads to a generally lower temperature of the medicinal solution in the inf...
