Problems solved by technology

For now, it can only be judged by the patient's direct observation of the droplet velocity in the Murphy's dropper. However, since the infusion tube is usually located next to the human body, it is necessary to turn the head to check it. is very inconvenient
Therefore, the patient usually observes the dropper after a long period of time, and often the drop speed is super slow or super fast.

Embodiment 1

[0018] exist figure 1 , 2 . In the first embodiment shown in 3, the reminder type medical infusion heating device includes a tubular shell 1 clamped on the outside of the infusion tube, and the inside of the tubular shell 1 includes a constant temperature chamber 2 and a refrigeration chamber 3 from top to bottom; The constant temperature chamber 2 is provided with a temperature sensor 20 and a heating device 21 that are jointly coupled to a heating control module (not shown), so that the liquid medicine flowing through the constant temperature chamber 2 is kept at a predetermined temperature; The heating power of the heating device 21 is controlled to achieve constant temperature requirements. The heating device 21 can be an electric heating wire or an electric heating film; the outer periphery of the constant temperature chamber 2 is composed of a heat insulating layer 22 . The predetermined temperature is a certain temperature between 40° C. and 45° C., so that after bein...

Embodiment 2

[0023] for Figure 4 The second embodiment shown is different from the first embodiment in that the upper part of the constant temperature chamber 2 inside the tubular housing 1 also includes a preheating chamber 4, and the preheating chamber 4 is provided with an arc-shaped 1. The metal sheet 41 that can be clamped on the surface of the infusion tube 9 is made into two arc-shaped sheets the same as the semiconductor cooling sheet 31; the metal sheet 41 extends downward to the hot surface of the semiconductor cooling sheet 31; And the metal sheet 41 does not exchange heat with the constant temperature chamber 2 . Thereby, the heat surface of the semiconductor cooling chip 31 can be rapidly dissipated, and the heat can not be dissipated to the outside, but can be fully utilized to preheat the drug solution, which has the effect of killing two birds with one stone.

Abstract

The invention provides a reminding type medical infusion heating device. The reminding type medical infusion heating device comprises a tubular shell clamped outside an infusion tube, wherein the interior of the tubular shell at least comprises a constant-temperature cavity and a refrigerating cavity from top to bottom; a temperature sensor and a heating device which are jointly coupled to a heating control module are arranged in the constant-temperature cavity, so that a liquid medicine flowing through the constant-temperature cavity is kept at a preset temperature; an arc-shaped semiconductor chilling plate capable of being clamped on the surface of the infusion tube in a wrapping mode is arranged in the refrigerating cavity, and the cold face of the semiconductor chilling plate is keptin heat conduction contact with the infusion tube. The device not only can heat the liquid medicine, but also can enable a patient to sense the infusion speed in real time.

Description

technical field [0001] The invention relates to the field of medical facilities, in particular to a heating device for an infusion system. Background technique [0002] The infusion heater is a relatively common medical auxiliary device, which is mainly used to heat the liquid medicine in the infusion tube. The current infusion heater is usually directly clamped on the outside of the infusion tube, and the medicinal liquid in the infusion tube is heated by an electric heating device. [0003] Since the human body is a constant temperature system, and the external temperature changes with the seasons, the initial temperature of the medicinal liquid changes greatly. Therefore, in order to meet the comfort of infusion, the current infusion heaters are basically designed as constant temperature heaters, that is, to make the medicinal liquid flowing through the infusion heater stable at a set temperature. [0004] However, since the infusion tube is made of plastic, the heat pr...
