Use and maintenance of infusion set

Infusion sets can generally be divided into two categories: one is an infusion set, and the other is a micro syringe. The infusion set is mainly designed for the patient's infusion, it can accurately deliver the liquid according to the need; the micro syringe is mainly used when the output per unit time is small or the unit time has high accuracy, and it is most suitable for manual operation. Of the drug, micro-infusion. At present, it is widely used in the rescue and monitoring of critically ill patients, such as intravenous infusion, arterial infusion, peritoneal dialysis, contrast agent, and anesthetic injection.

Peristaltic infusion set should be noted that the infusion set and the infusion strap should match, adjust the feed rate as needed, and then start to work. The micro syringe barrel should be of the specified model. If the replacement barrel will cause the error of liquid injection per unit time, the feed rate must also be adjusted. Pay special attention not to drip the liquid on the instrument during use. If it happens, wipe it dry in time to prevent the liquid from entering the machine and causing machine malfunction. According to the instructions, the infusion set should be measured for various indicators, the most important thing is the accuracy test.

The general infusion set can be composed of a liquid propelling device, a digital display, a control part and an alarm part. The pushing device can be divided into peristaltic type, rolling type, piston type and screw barrel type. At present, most of the infusions use the peristaltic type. It is a row of presser feet that sequentially squeeze and relax the leather strap, so as to achieve the effect of pushing the liquid. In this way, the pressure and release of the presser foot is like a peristaltic way, speeding up The peristaltic frequency can increase the liquid flow rate. The micro-injector uses a screw to change the rotary motion into linear motion. On one side of the screw, there is a linear grating that moves with it. It can accurately measure the flow rate with an accuracy of 0.1ml/h. The driving force of the device is generally a hollow cup motor, which has a small moment of inertia. For control, the motor voltage adopts DC pulses, and there is a grating on the motor shaft to control the rotation of the motor.

Because the liquid is directly injected into the patient's vein, which is largely related to the safety of the patient, there must be an alarm system to stop the infusion in time when an abnormal situation occurs, and send out a light alarm and a buzzer alarm, which is handled by medical staff in time. The alarm can have a pressure alarm for whether the infusion set is blocked, and a liquid alarm for the knowledge of whether the liquid is used up and the bubble alarm in the infusion tube. The working status of all functions is executed by the microprocessor.
