Description

Heating monitoring device of infusion tube

Technical Field

Background

The infusion refers to a large dose of injection which is infused into the body by intravenous drip, and the administration is more than 100ml once; it is a branch of injection, usually packed in glass or plastic infusion bottle or bag, without bacteriostatic agent; when in use, the dropping speed is adjusted by the infusion apparatus, and the medicine is continuously and stably infused into the body. However, because of storage requirements, some injectates must be refrigerated; generally speaking, the storage temperature of the liquid medicine is lower than 20 degrees, the temperature of the liquid medicine is lower in winter, and particularly, the blood is refrigerated in a refrigerating chamber and the temperature is lower. When the cold-stored injection or the infusion is carried out in cold weather, the temperature of the injection in the infusion bottle/infusion bag is greatly different from the temperature of a human body; the liquid medicine with lower temperature can stimulate blood vessels, so that when a patient transfuses, the puncture part feels particularly painful due to cold stimulation, and some weak patients can also have uncomfortable manifestations such as cold tremor. Therefore, when a patient is transfusing, the patient usually holds the infusion tube with a hand to increase the temperature of the liquid medicine, or heats the injection in the infusion tube with a hot water bag. However, since hot water is added into the hot water bag at one time, the injection cannot be heated sufficiently due to rapid cooling, and the heating effect is poor.

Moreover, the infusion tube of the existing disposable infusion set is easy to bend, and is not easy to be found if the infusion tube occurs in an operation; the serious consequences such as the awareness in the operation and the like are easy to happen due to the unsmooth liquid path, and huge physical and psychological damage is brought to the patient. In a general ward, after the injection runs out, a nurse is only required to be informed of changing the medicine through the family members of the patient, and if the patient is in a hospital and falls asleep by a single person, the condition that the injection drips out cannot be found in time. Moreover, the existing injection heating device can only heat but cannot alarm and feed back so as to remind medical care personnel.
