Description

Multifunctional infusion control system

Technical Field

The invention belongs to the technical field of medical instruments, and particularly relates to a multifunctional infusion control system.

Background

Infusion, also known as drip infusion or drip infusion, is a large dose of injection infused into the body by intravenous drip. Are usually packaged in glass or plastic infusion bottles or bags and contain no preservatives or bacteriostatic agents. When in use, the infusion apparatus is used for adjusting the dropping speed to continuously and stably enter the vein so as to supplement body fluid, electrolyte or provide nutrient substances, and becomes one of the most common and most direct effective clinical treatment means.

Most of the existing syringes are only provided with a manually-adjusted flow switch to adjust the transfusion titer, and the dripping speed is too fast, so that the heart burden of a patient is easily increased, local stimulation is caused, phlebitis is caused, anaphylactic reaction is easily caused, renal function damage and other symptoms are easily caused. The slow dropping speed can affect the drug effect and prolong the infusion time, so the infusion titer is determined by various aspects such as drugs, disease conditions and the like, and has strict requirements. The manual regulating switch is inaccurate in speed regulation, and the patient often steals the speed regulation by oneself, and medical personnel can not discover in time, easily takes place medical malpractice.

In order to prevent accidents in the infusion process, the infusion progress needs to be continuously monitored, and most of the monitoring modes at the present stage are that a patient or family members always look at an infusion bottle until liquid injection is completed, so that medical personnel are called, and the medical personnel pull up the needle. In the process, the patient or the family members need to keep staring at the infusion progress, cannot have a rest, and wastes time and labor. When medical personnel receive a call, the medical personnel need to arrive in time, the preparation cannot be made in advance, after the arrival, the transfusion process is not completed, a certain time still needs to be waited, the time is wasted, and the working efficiency of the medical personnel is influenced.

When the temperature of the injection liquid in the injection bottle is too low or the temperature of the medicine has special requirements, the injection liquid needs to be heated to a certain temperature so as to be injected into the body of a patient. The injector at the present stage does not have a heating function, and has the advantages of large volume of a device specially used for heating injection, responsible operation, high cost and unsuitability for clinical use.
