Embodiment 1

[0012] Embodiment 1: Description of the technical features of the liquid heater for the infusion set with reference to the accompanying drawings: the heating electrical components and the circuit board are installed inside the heater shell 1, and the heat generated by the heating electrical components is conducted to the surface to set up a protrusion The panels of 2 and 3, the slender hose at the end of the infusion set is wound between the protrusions 2 and 3 on the panel to be heated, the electric energy is introduced into the heater through the power cord 4, and the heater cover 5 pairs of slender hose and liquid medicine Insulation, the position where the hose enters and exits the heater is restricted by the outlet and inlet 6, 8 on the cover, the cover reserves a gap 7 for the position of the power cord 4, and the cover and the heater shell are linked by a hinge (hinge) 9, as shown in the figure The hinge structure is just an example of a hinge, and a built-in link struct...

Embodiment 2

[0013] Embodiment 2: As an alternative, the main components of the above-mentioned heater are simplified as: heating electrical components, power lines, power switches, circuit boards, and heater shells. Cancel the switching circuit, or use a thermal relay (a temperature-sensitive relay, when the temperature rises to a certain value, the circuit is automatically disconnected and heating is stopped) to replace the "temperature sensor, temperature detection circuit and switching circuit".

[0014] The components of the heater can also be simplified as a heating electrical element, a power cord, a heating panel, and a heater shell. The power switch can also be omitted.

[0015] As an alternative to a power supply, a power switch or a power cord, the extended end of the power cord 4 of the heater described above adopts a USB plug, so that the heater can use the power supply of the USB interface, and the power supply includes but is not limited to a USB power socket ( Including th...

Embodiment 3

[0018] Embodiment 3: temperature control and power switch, also can choose knob type power switch and temperature regulator. Temperature control is the easiest way to control the temperature of the heater panel. It is also possible to adopt the method of controlling the temperature of the output liquid medicine, detect the temperature of the infusion hose at the outlet of the heater, and then control the temperature of the panel.

[0019] The components, parts, circuits, connection methods and sequences in the above-mentioned embodiments and the product of the liquid heater for the infusion set are familiar to those skilled in the art, and no creative labor is required to implement the technical solution and obtain the heater product .

Abstract

The invention discloses a medicine liquid heater for an infusion apparatus, and relates to an auxiliary medical instrument. The medicine liquid heater is used for heating the thin and long hose, close to a syringe needle, of the tail end of the infusion apparatus and medicine liquid conveyed in the thin and long hose; an electric heating component heating method is adopted, therefore, the medicine liquid is heated to have the temperature appropriate to the body temperature of a patient and then conveyed into the body of the patient, and the comfort of the patient in the infusion process is improved.

Description

technical field [0001] The invention belongs to auxiliary medical equipment, which is a small electrical product. Background technique [0002] An infusion set is a commonly used medical device, generally including a medicine bottle, a hose, a throttle controller, a liquid droplet velocity observation tube, a slender hose, a needle, etc., and is usually used to deliver medicine or mixed medicine to the human vein . [0003] In the cold season, especially in an environment without heating, patient infusion is a painful thing. When the medicinal liquid enters the patient's body, the patient will feel cold and uncomfortable at the part of the body where the needle is inserted into the medicine. Some drugs need to be stored under low temperature conditions to ensure that the quality of the drug will not change during storage. We can often see nurses taking out the medicine solution to be used from the refrigerator. After the medicine solution is prepared, it is directly injec...
