Background technology
In existing blood cleaning equipment, the blood of patient flows out via pipeline and purifier in body, return in body, form an extracorporeal circulation system, blood purification realizes disperse, convection current by using dialyser or the intermembranous pressure of filter, mould is excessive to be exceeded normal range and will cause rupture of membranes, causes blood leakage, thus jeopardizes patient vitals's safety.Therefore, leak blood and monitor very important, leakage blood monitoring device is exactly the parts for detecting dialyser rupture of membranes, when dialyser rupture of membranes generation blood leakage, leaks blood monitoring device and sends alarm signal.
Traditional leakage blood checkout gear comprises power circuit, optical transmission circuit, optical receiving circuit, signal amplification circuit and signal processing circuit, wherein power circuit is powered for other each element circuit, optical transmission circuit and optical receiving circuit are arranged on by the waste fluid channel of Lou blood checkout gear, wherein optical transmission circuit adopts the mode of infrared emission to produce optical signal, optical receiving circuit adopts infrared acquisition mode and optical lens by means of complexity produces and picks up photosignal, and generate current signal, signal amplification circuit does Shape correction to this current signal and formation voltage signal exports to signal processing circuit, transmit signal to signal processing circuit again to make comparisons process.This signal processing circuit adopts simple comparator technology to realize, and sends alarm signal by voltage compare.Its shortcoming is: transmitting very green and the red diode of traditional blood leakage detector, output signal is analog quantity, bubble etc. easily in and waste liquid stained by component aging, structural member affects, there is phenomenons such as reporting by mistake, fail to report, and self-inspection can not be carried out to the function of leaking blood, reduce stabilization of equipment performance, easily cause malpractice.
Summary of the invention
Because the above-mentioned defect of prior art, technical problem to be solved by this invention is to provide a kind of blood purification that can improve warning accuracy and leaks blood monitoring system.
For achieving the above object, the invention provides a kind of blood purification and leak blood monitoring system, comprise housing, fluid reservoir and power module; Described housing is light-proof material, and described fluid reservoir is transparent material, and described fluid reservoir is wrapped in described housing; The side of described fluid reservoir is provided with light-emitting device; Described light-emitting device comprises the first light emitting diode, and described first light emitting diode sends white light; The opposite side of described fluid reservoir is also provided with color sensor; The input of the outfan connection control circuit of described color sensor; The outfan of described control circuit connects the input of described light-emitting device; Described power module is powered to described light-emitting device, color sensor and control circuit.
Described control circuit controls light-emitting device and sends white light, light is radiated on color sensor by the fluid reservoir filling transparency liquid, color sensor tests out HONGGUANG in white light, green glow and blue light signals amount, using the optical signal amount measured for the first time as monitoring criteria value, the signal detected is passed to control circuit by color sensor; When there being blood in fluid reservoir, white light through fluid reservoir becomes HONGGUANG and impinges upon on color sensor, color sensor senses HONGGUANG and exports data to control circuit, the optical signal amount measured and the monitoring criteria value recorded for the first time compare by control circuit, thus the monitoring of leakage blood is carried out to blood cleaning equipment, in the situations such as fluid reservoir is stained, still can realize accurate warning, the wrong report avoiding therefore producing, fail to report phenomenon and occur, the stability of support equipment and reliability.
Preferably, described light-emitting device also comprises the second light emitting diode, described control circuit controls light-emitting device and sends HONGGUANG, optical signal is changed into the signal of telecommunication and passes to control circuit and carry out self-inspection by color sensor, owing to can carry out simulating the function self-inspection of leaking blood, ensure that Lou blood monitoring system can be in normal monitoring state, ensure that the safety of equipment.
The invention has the beneficial effects as follows: the present invention is by monitoring liquid color, avoid tradition and leak blood monitoring system because fluid reservoir is stained or bubble in liquid disturbs and produces false alarm, the present invention can carry out automatic calibration to color sensor, avoid the impact of the situations such as photoelectric device is aging on sensor accuracy of detection, substantially increase the reliability of this leakage blood monitoring system, described leakage blood monitoring system can carry out simulating the function self-inspection of leaking blood, ensure that this leakage blood monitoring system can be in normal monitoring state, ensure that the safety of equipment.
