Method for controlling number of infusion drops

Abstract

The invention belongs to medical equipment, and relates to medical, nursing and electronic technology, in particular to a method for controlling the number of infusion drops. The method is characterized in that the method at least comprises an infusion bottle, a flowing-liquid needle and an infusion hose which connect the infusion bottle with a transparent dropper, and the number of infusion drops is controlled by detecting the speed of dropping liquid in the transparent dropper and controlling the air inflow and air outflow of the infusion bottle. A light-emitting circuit and a light-receiving circuit are arranged outside the infusion bottle; the light-emitting circuit and the light-receiving circuit are connected with a processing circuit; the processing circuit controls an air valve and an air pump; the air pump is connected with an air-inlet needle of the infusion bottle; and the amount of air inflow and air outflow is automatically controlled according to needed infusion speed so as to realize full-automatic infusion control. Therefore, the method has the advantages of guaranteeing the precise infusion of medicaments and liquid, reducing the psychological and economic burden of patients, saving the working time of nurses for counting drops and reducing doctor-patient dispute, along with high technological content, low energy consumption and convenience for popularization and application.

Description

technical field [0001] The invention belongs to a kind of medical equipment, relates to medicine, nursing science and electronic technology, in particular to a method for controlling the number of transfusion drops. Background technique [0002] The number of conventional infusion drops is completed by the plastic regulator on the disposable infusion set. Improper use or quality problems can easily cause the governor to overpress, automatically reset or the pulley slips out, resulting in unstable infusion speed and large infusion volume errors In clinical practice, most patients complain that the infusion time is long, which affects work and life, etc. Especially in the first aid of patients with massive hemorrhage and cerebral edema, rapid infusion or infusion of dehydrating agent is required, that is, rapid and effective adjustment of the number of infusion drops is required. Existing infusion pumps can undertake precise infusion functions, but they are expensive, and some...

Problems solved by technology

[0002] The number of conventional infusion drops is completed by the plastic regulator on the disposable infusion set. Improper use or quality problems can easily cause the governor to overpress, automatically reset or the pulley slips out, resulting in unstable infusion speed and large infusion volume errors In clinical practice, most patients complain that the infusion time is long, which affects work and life, etc.; especially in the first aid of patients with massive hemorrhage and cerebral edema, rapid infusion or infusion of dehydrating agent is required, that is, rapid and effective adjustment of the number of infusion drops is required.

The existing infusion pump can undertake the function of precise infusion, but it is expensive, and sometimes there are failures such as battery exhaustion and improper installation of the drop sensor, which affect the accuracy of the number of infusion drops, that is, the popularization and application are limited.
