Description

A kind of blood purification is with leaking the blood monitoring device
Technical field
This utility model relates to a kind of haemodialysis control unit parts, particularly relates to a kind of blood purification with leaking the blood monitoring device.
Background technology
In existing blood cleaning equipment, patient's blood flows out via pipeline and purifier in body, return in the body, consist of an extracorporeal circulation system, blood purification is by using dialyser or the intermembranous pressure of filter to realize disperse, convection current, mould is excessive to be exceeded normal range and will cause rupture of membranes, causes blood leakage, thereby jeopardizes patient's life security.Therefore, the monitoring of leakage blood is very important, and leakage blood monitoring device is exactly the parts for detection of the dialyser rupture of membranes, when dialyser rupture of membranes generation blood leakage, leaks the blood monitoring device and sends alarm signal.
Traditional leakage blood examination is surveyed device and is comprised power circuit, optical transmission circuit, optical receiving circuit, signal amplification circuit and signal processing circuit, wherein power circuit is other each element circuit power supply, optical transmission circuit and optical receiving circuit are installed in Lou blood examination and survey by the waste fluid channel of device, wherein optical transmission circuit adopts the mode of infrared emission to produce optical signal, optical receiving circuit adopts the infrared acquisition mode and produces and pick up photosignal by means of the optical lens of complexity, and generation current signal, this current signal is done Shape correction to signal amplification circuit and the formation voltage signal is exported to signal processing circuit, transmits signal to the signal processing circuit processing of making comparisons again.This signal processing circuit adopts simple comparator technology to realize, sends alarm signal by voltage ratio.Its shortcoming is: the emission of traditional blood leakage detector is green and red diode very, output signal is analog quantity, easily be subjected to component aging, structural member is stained and waste liquid in bubble etc. affect, phenomenons such as reporting by mistake, fail to report appears, and can not carry out self check to the function of leaking blood, reduce stabilization of equipment performance, easily caused malpractice.
The utility model content
Because the defects of prior art, technical problem to be solved in the utility model provides a kind of blood purification of warning accuracy that can improve with leaking the blood monitoring device.
For achieving the above object, this utility model provides a kind of blood purification with leaking the blood monitoring device, comprises 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 the described housing; One side of described fluid reservoir is equipped with light-emitting device; Described light-emitting device comprises the first light emitting diode, and described the first light emitting diode sends white light; The opposite side of described fluid reservoir also is provided with color sensor; The outfan of described color sensor connects the input of control circuit; The outfan of described control circuit connects the input of described light-emitting device; Described power module is to described light-emitting device, color sensor and control circuit power supply.
Described control circuit control light-emitting device sends white light, light is radiated on the color sensor by the fluid reservoir of filling transparency liquid, color sensor tests out HONGGUANG in the white light, green glow and blue light semaphore, as the monitoring criteria value, color sensor is passed to control circuit with the signal that detects with the optical signal amount measured for the first time; When in the fluid reservoir blood being arranged, the white light that sees through fluid reservoir becomes HONGGUANG and impinges upon on the color sensor, color sensor is sensed HONGGUANG and is exported data to control circuit, control circuit compares the optical signal amount that measures and the monitoring criteria value that records for the first time, thus blood cleaning equipment is leaked blood monitoring, in the situations such as fluid reservoir is stained, still can realize accurate warning, the wrong report of avoiding so producing, fail to report phenomenon the stability of support equipment and reliability occur.
Better, described light-emitting device also comprises the second light emitting diode, described control circuit control light-emitting device sends HONGGUANG, color sensor changes into the signal of telecommunication with optical signal and passes to control circuit and carry out self check, owing to can simulate the Lou function self check of blood, guaranteed that leakage blood monitoring system can be in normal monitoring state, has guaranteed the safety of equipment.
The beneficial effects of the utility model are: this utility model is by monitoring liquid color, stained or bubble in liquid disturbs and produces false alarm because of fluid reservoir to have avoided traditional leakage blood monitoring system, this utility model can carry out automatic calibration to color sensor, avoided the situations such as photoelectric device is aging on the impact of sensor accuracy of detection, greatly improved the reliability of this leakage blood monitoring system, described leakage blood monitoring system can be simulated the Lou function self check of blood, guaranteed that this leakage blood monitoring system can be in normal monitoring state, has guaranteed the safety of equipment.
