Embodiment 1

[0035] 5g Na 2 SO 4 10H 2 O crystal powder is packaged in polyester plastic covered with metal aluminum film as an insulation layer. Carbon fiber is used as the heating medium, the resistance is 5Ω, and it is connected to the USB interface through wires as the heating layer. Use polyurethane foam with a thickness of 3mm as the insulation layer. After the layers are connected by adhesives, they are packed into a cylindrical polyvinyl chloride plastic protective layer. The USB interface of the heating layer is connected to 220V AC through the charger data cable, and the temperature of the liquid flowing out of the infusion tube is 28~30°C.

Embodiment 2

[0037] 10g Na 2 SO 4 10H 2 O crystal powder is packaged in a metal aluminum film with a thickness of 0.1mm as an insulation layer. Carbon fiber is used as the heating medium, the resistance is 4Ω, and it is connected to the USB interface through wires as the heating layer. Use polystyrene foam with a thickness of 5mm as the insulation layer. After the layers are connected by adhesives, they are packed into a rectangular polyacrylonitrile-butadiene-styrene (ABS) plastic protective layer. The USB interface of the heating layer is connected to the mobile power supply through the data cable, and the temperature of the liquid flowing out of the infusion tube is 26~28°C.

Embodiment 3

[0039] 7g Na 2 SO 4 10H 2 O crystal powder is packaged in a metal copper film with a thickness of 0.1mm as an insulation layer. Carbon fiber is used as the heating medium, the resistance is 4Ω, and it is connected to the USB interface through wires as the heating layer. Cotton with a thickness of 5mm is used as the insulation layer, and the layers are connected by adhesives, and then put into a rectangular prism-shaped stainless steel protective layer. The USB interface of the heating layer is connected to the USB interface of the notebook through the data cable, and the temperature of the liquid flowing out of the infusion tube is 27~28°C.

Abstract

The invention relates to a portable infusion heating device taking mirabilite as a thermal insulation material as well as a manufacturing principle and a manufacturing method of the portable infusion heating device. The technical principle of the portable infusion heating device is as follows: (1) a USB interface is adopted as a power interface, and a resistor in a USB heating layer is electrified to heat by utilizing the joule effect of an external power supply; and (2) mirabilite is adopted for indirectly heating liquid medicine in an infusion tube. From outside to inside, the portable infusion heating device comprises but is not limited to the following four layers: a packaging protective layer, a thermal insulation layer, a USB heating layer and a mirabilite thermal insulation layer, and a power supply with the USB interface can be taken as a power supply for the thermal insulation thermal infusion device. The infusion heating device manufactured by adopting the method provided by the invention has the advantages that the cost is low, the raw materials are easily available, the process is simple, the volume production can be realized, and the repeated use is available; the heating effect is good, overheating can be avoided, the structure is small and exquisite, the use is convenient, and the device can be applied to the medical field.

Description

technical field [0001] The invention relates to the field of medical auxiliary equipment, in particular to a portable infusion heating device with mirabilite as heat preservation material and its manufacturing principle and method. The infusion heating device manufactured by the invention can be used for constant temperature heating of infusion medicines, and reduces the cold feeling and related symptoms caused by infusion patients to low-temperature liquid medicines. Background technique [0002] In the cold winter, when the patient is transfused, the low-temperature liquid medicine enters the infusion recipient's body, which often causes the infusion recipient to feel cold. Especially in the case of long-term infusion, the body temperature of the infusion body, such as the arm, etc., will drop significantly, and the infusion patient may even experience biting pain. Due to the large difference between the temperature of the input liquid and the blood of the human body, it ...
