Description
Technical Field
The utility model relates to the technical field of medical treatment, in particular to an infusion device convenient to control and switch.
Background
Currently, in clinical care, the infusion of drugs is one of the most common and necessary therapeutic approaches. And when the liquid such as cryoprecipitate is infused, the liquid needs to be frequently replaced within a short time, and the nursing staff must frequently run the ward to replace the medicine, so that repeated and large amount of work is caused. If the patient can not be replaced in time, the treatment of the patient can be delayed.
In addition, the rate of infusion will vary from drug to drug, and from subject to subject, with each drug having its optimal rate of infusion. This requires that the medical personnel must readjust and confirm the infusion rate after switching over the medication. However, the speed determination is generally performed by a caregiver's timer count, which takes time. At the same time, the infusion rate is also dynamically influenced by various factors, such as pressure differences, vascular conditions, drug composition, etc.
In order to solve the above problems, many attempts have been made in the art, such as the common solutions: the timer switching scheme is that in the using process, the next medicine is switched after the time is up through the preset time. The disadvantages of this solution are: the timing scheme can only be used for simple estimation, is not accurate enough, and can cause the risk of blood backflow of a patient when the input amount of the medicine is insufficient or the medicine is switched untimely due to the fact that the first bag of medicine is switched too early or too late in most cases.
For another example, chinese patent application CN 109106996 a judges whether the drug is infused or not and switches the drug by physical methods such as floating, and the disadvantages of this solution include:
1. although the method for physical judgment is simple to implement, the flexibility is not enough, only a single medicine switching action can be performed, and the infusion speed cannot be dynamically adjusted according to the medicine variety, so that the infusion speed of the system still needs to be adjusted by the presence of a nursing staff when the system is switched to the second bag of medicine;
2. in addition, the infusion speed is also dynamically influenced by various factors, such as pressure difference, blood vessel conditions, medicine components and the like, and even if the same bag of medicine is used, the pressure is different at the early stage and the later stage of infusion due to different medicine quantities, so that the infusion speed of the medicine is deviated to a certain extent.
