Description
Technical field
The present invention relates to the automatic monitoring equipment of a kind of hospital and family's drop process, belong to medical field of auxiliary.
Background technology
Medical science venous transfusion is clinical medical critical treatment means, and what the mode of most drop was applied is gravity principle, and medicine bottle or medicated bag hang on infusion stand, and the medicinal liquid in bottle can down drip.In drop process, care provider is needed to observe the speed of drop and process.Due to the drop time can not be estimated accurately, in drop process, entourage is needed to close injecting medical liquid surplus at any time, time one is long very tired, especially at night, this phenomenon is more general, brings nervous and tired and inconvenience to patient and entourage.So there is following limitation in drop:
If 1. transfusion drip speed is improper may cause patient body discomfort even threat to life safety;
2. transfusion time is long, easily causes nursing staff and patient's carelessness, increases malpractice hidden danger;
3. need to monitor infusion process at any time, add the working strength of nursing staff, consume the energy of patient entourage.When medicinal liquid drips off soon, need Timeliness coverage, allow medical personnel change dressings or terminate drop, otherwise just there will be in air intravasation and form aeroembolism, the situations such as blood coagulation blocking syringe needle, gently then delay treatment, heavy then entail dangers to patients ' lives safety, generation malpractice.
In order to solve in venous transfusion to the series of problems that patient and medical personnel bring, realize the intelligent monitor of infusion process better, for many years, both at home and abroad all for this has been a large amount of experiments and research, have developed multiple transfusion monitoring equipment, its developing history mainly comprises following so several stage.
1. the mechanical infusion monitoring stage: just someone proposes a kind of detection method of mechanical infusion bottle liquid level as far back as 1985 time, the method is that the principle utilizing the decline of liquid level in infusion bottle that its weight can be caused to decline detects its liquid level, the main tool used is spring scale, be used for weighing the weight of medicinal liquid bottle, but the situation of reality is comparatively complicated, the weight of medicine bottle is diversified, therefore the reliability of this kind of method is very poor, and use inconvenience, be not suitable for applying.
2. the condenser type infusion monitoring stage: the principle of condenser type infusion monitoring utilizes the change of liquid level in infusion bottle that the principle of capacitance variations can be caused to monitor the liquid level in infusion bottle, but the volume size due to the infusion bottle in clinical transfusion has a variety of, if want adopting said method just to need to design multiple different transfusion monitoring equipment, this can bring great inconvenience to the use of medical personnel, is therefore not suitable for applying.
3. the electric pole type infusion monitoring stage: the principle of electric pole type infusion monitoring utilizes two electrodes inserting Murphy type pipe to realize, when there is drop process the centre of electrode time, can produce the signal of interruption, this feature can be monitored this physical quantity of the speed of drop.The means of this monitoring are simply effective, but due to this mode be need to contact with medicine, easily pollution is produced to medicine, and then has influence on the therapeutic effect of venous transfusion, be therefore not suitable for applying.
Although these modes above mentioned can both complete the task of infusion monitoring, but its in sensitivity, the medicinal liquid scope of application, operational approach, production cost etc. more or less there are some problems, so promoting the use of of could not succeeding on medical device market so far.The domestic automatic monitoring problem solving transfusion not yet completely at present, in the RELATED APPLICATIONS that oneself has, its principle is the alarm of mechanical type, optical reflection type and gravity type, volume is large, cost is high, for becoming real product, in sensitivity, accuracy rate, the medicinal liquid scope of application, operational approach and production cost, size, weight etc., there are problems, so none can successfully be introduced to the market so far.
