Embodiment 1

[0035] 5g CaCl 2 ·6H 2 O crystal powder is packaged in polyester plastic covered with metal aluminum film as an insulation layer. The resistance 5Ω metal film is printed on the polyester to form a labyrinth circuit, which is used as a heating medium and connected to the USB interface through wires to form a heating layer. Use polyurethane foam with a thickness of 4mm 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 26~27°C.

Embodiment 2

[0037] 10g CaCl 2 ·6H 2 O crystal powder is packaged in a metal aluminum film with a thickness of 0.1mm as an insulation layer. The resistance 3Ω metal film is printed on the polyester to form a labyrinth circuit, which is used as a heating medium and connected to the USB interface through wires to form a heating layer. Use polystyrene foam with a thickness of 5 mm 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 CaCl 2 ·6H 2 O crystal powder is packaged in a metal copper film with a thickness of 0.1mm as an insulation layer. The resistance 4Ω metal film is printed on the polyester to form a labyrinth circuit, which is used as a heating medium and connected to the USB interface through wires to form a 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 with calcium chloride serving as a heat insulation material and a manufacturing principle and method thereof. The technical principle is that a USB interface is used as a power interface, and a resistor in a USB heating layer is electrified by means of the joule effect of an external power supply, so as to generate heat; and liquid medicine in an infusion tube is indirectly heated by means of calcium chloride. The portable infusion heating device comprises but is not limited to four layers from outside to inside, and the four layers are the packaging protective layer, the heat insulating layer, the USB heating layer and the calcium chloride heat insulation layer. Any power supply with a USB interface can serve as a power supply of a heat insulating infusion device. The infusion heating device has the advantages that the cost is low, raw materials are easy to obtain, the process is simple, and the device is suitable for bulk production and can be repeatedly used; the heating effect is good, and overheating can be avoided; the size is small, and using is convenient; and the device can be used in 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 using calcium chloride as a thermal insulation 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...
