Technical Field

[0001] The utility model relates to the technical field of infusion, in particular to an infusion heater. Background Art

[0002] An infusion heater is generally installed on an infusion tube (nasogastric tube, enteral nutrition tube, etc.), and the infusion is heated at a constant temperature to avoid the infusion being too cold and causing discomfort to the patient.

[0003] The existing infusion heater heats by directly clamping a heating clip on the infusion tube. However, the outer shell of this heating clip is prone to heat up and is not very easy to scald the skin; moreover, it is directly connected to the mains socket through a wire, which is not only inconvenient but also has potential safety hazards.

[0004] Therefore, we propose an infusion heater. Content of the Utility Model

[0005] In view of this, the utility model provides an infusion heater to solve the problems that the heating clip in the prior art is prone to overheat and is inconvenient.

[0006] An infusion heater includes an elastic rubber sleeve. One side of the elastic rubber sleeve is provided with a cut that is cut along the axis, and both sides of the cut are respectively fixedly connected to the outer sides of the two clamping plates of the heating clip; wherein, one side of the elastic rubber sleeve is connected to a housing. The housing is internally provided with a soft-pack lithium battery and a single-chip microcomputer. A display screen for displaying temperature is installed on the surface of the housing. The connecting wire on one side of the heating clip penetrates through the elastic rubber sleeve and extends into the housing to be connected to the single-chip microcomputer. A temperature sensor is installed in one of the clamping plates of the heating clip.

[0007] Preferably, the signal output end of the temperature sensor is connected to the signal input end of the single-chip microcomputer, the heating element is controlled by the single-chip microcomputer, and the signal output end of the single-chip microcomputer is connected to the display screen.

[0008] Preferably, a heating chamber is arranged in the clamping plate of the heating clip. Notches for facilitating clamping on the infusion tube are arranged at both ends of the heating chamber; a heating element is installed in the heating chamber.

[0009] Preferably, the heating element is set as a graphene heating film, an infrared heating lamp or an electric heating wire.

[0010] Preferably, one end of the housing is provided with a charging port for charging the soft-pack lithium battery, and a power indicator is installed at one end of the upper surface of the housing.

[0011] Preferably, a working indicator is arranged at one end of the surface of the housing.

[0012] Preferably, an operation button is installed at one end of the above-mentioned housing.

[0013] Implementing the embodiments of the present utility model will have the following beneficial effects:

[0014] By adopting the above-mentioned infusion heater,

[0015] By sleeving an elastic rubber sleeve outside the heating chamber, it can prevent the patient's skin from directly contacting the heating clamp and avoid scalding;

[0016] The elastic rubber sleeve does not affect the opening and closing of the heating clamp and is convenient to use;

[0017] Moreover, the elastic rubber sleeve can maintain a certain distance from the surface of the heating clamp under the action of the elastic restoring force, and will not directly fit and transfer heat, so the elastic rubber sleeve will not get hot;

[0018] By setting a soft-pack lithium battery, there is no need to connect to the mains electricity through wires, and the soft-pack lithium battery is light in weight and convenient to use; especially in the case of potential safety hazards, the soft-pack battery will at most bulge and crack, which is very safe;

[0019] By setting a display screen, the temperature inside the heating chamber can be displayed in real time, which is very convenient. BRIEF DESCRIPTION OF THE DRAWINGS
