Description
Technical Field
The invention relates to the technical field of medical treatment, in particular to an intelligent infusion system.
Background
Intravenous infusion is used as a treatment means, the use frequency is high, hospitals need to provide a wide infusion area, and a large number of medical staff are needed to monitor the infusion process. The traditional mode of manually monitoring the infusion process by medical staff not only needs to consume a great deal of manpower and energy, but also has low efficiency, and even can cause serious medical accidents due to negligence.
In view of this, in recent years, many studies have been made in the field of infusion monitoring management, and various liquid medicine monitoring schemes have been proposed, mainly including mechanical, electrode, capacitive, and photoelectric types. The mechanical monitoring is divided into a spring type and a weighing type, the spring type utilizes the deformation of a spring to obtain the weight change of the liquid medicine, the calculation is complex, the error is large, and the mechanical structure of the spring is not easy to maintain. The weighing type monitoring is to measure the variation of the liquid medicine in a period of time through a gravity sensor so as to judge the related state of the transfusion, and has low precision and low reliability. The electrode type monitoring is that positive and negative electrodes are inserted into the infusion tube, the micro-particles ionized from the liquid medicine are driven to the electrode plates at two ends by positive and negative electrodes, so that the electrode plates generate potential change, and algorithm calculation is carried out to finally obtain the available macroscopic physical quantity. The device has complex structure and poor performance, and the positive and negative electrodes may be polluted by direct contact with the liquid medicine. The capacitance type monitoring is that copper foil is attached to the periphery of a liquid medicine bottle, and the transfusion condition is judged according to the capacitance change, but the capacitance type monitoring is limited by the liquid medicine components and the shape of the liquid medicine bottle, and the use is inconvenient. The photoelectric monitoring is that infrared geminate transistors are arranged on two sides of the infusion tube, when the liquid medicine passes through, infrared light can be diffracted, and the liquid medicine dripping is detected by detecting the electric pulse change of the infrared receiving tube. The mode does not need to be contacted with liquid medicine, the signal detection is reliable, and the operation is simple, so the method is widely applied.
The current infusion system is mainly used for intelligently monitoring the infusion process by technical means, so that the manual monitoring process is reduced, and the labor consumption is reduced. In addition, however, the patient's own behavior is restricted by the patient's condition, which results in the need for an infusion call that is overly dependent on family members and medical staff, and the patient is under heavy mental stress. If the infusion call does not require the patient to pay too much attention and the call is ring, great benefits are provided for the patient's condition, the infusion safety and the reduction of the working pressure of the medical staff. However, the existing infusion system generally has single and dispersed functions, cannot cope with various abnormal situations of infusion, still needs to depend on the untimely tour of medical care personnel, and is easy to miss and leak.
