Description
Technical field
The present invention relates to blood plasma thawing instrument.
Background technology
Current blood plasma unfreezing apparatus generally adopts water to carry out the mode of heat treated as the thawing room of heat transferring medium, during heat treated, be all the foundation using the time as the terminal that thaws, during use, heat transferring medium can only be controlled by rule of thumb, to process in blood plasma temperature and the control difficulty on the processing time large.And blood plasma is packed, its core temperature and medium temperature are in processing procedure, and namely complete before thawing and there is comparatively large time delay temperature difference, heat exchange medium temperature can not reflect plasma bags internal temperature in real time.Extremes of temperature, the processing time is long too short, all can cause plasma fraction loss, and efficiency is low or energy consumption is high.And press clinical requirement, be kept at the blood plasma of less than-20 DEG C, needing to be warming up to more than 26 DEG C at short notice could keep plasma fraction constant, blood plasma can not be caused to damage more than 42 DEG C, and thaw point is uneven there will be fibrin deposition.Therefore the thaw safety of blood plasma of existing blood plasma unfreezing apparatus cannot be ensured completely.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of safety blood plasma thawing instrument, it is easy to control, can ensure safety during blood plasma unfreezing.
The present invention solves the problems of the technologies described above adopted technical scheme:
A kind of safety blood plasma thawing instrument, it comprises melts room, intensification room, calandria, condensate, circulating pump and temperature-control senser, and intensification room is arranged on the bottom of melting room; Intensification room is provided with entrance and exit, and the entrance of intensification room is connected with thawing room by condensate, and the outlet of intensification room is connected with thawing room by calandria, forms water circulation system; Described circulating pump is arranged on calandria;
The described indoor water temperature sensor be provided with for measuring water temperature that heats up, described thawing indoor are provided with the blood plasma temperature sensor for measure analog plasma bags internal temperature, the outfan input temperature-control senser of described temperature sensor.
In such scheme, described water temperature sensor is arranged on exit, intensification room.
The present invention is using indoor water temperature and the foundation of thawing lab simulation plasma bags core temperature as control heating process of heating up, and heating process easily controls, and can ensure safety during blood plasma unfreezing.
Described water temperature sensor is arranged on exit, intensification room, can guarantee the accuracy measuring water temperature, ensures safety during blood plasma unfreezing further.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the embodiment of the present invention, below the accompanying drawing used required in describing embodiment is briefly described.
Fig. 1 is embodiment of the present invention structural representation.
In figure: 1-melts room, 2-entrance, 3-exports, 4-intensification room, 5-simulating blood plasma bag, 6-plasma bags, 7-water temperature sensor, the temperature sensor of 8-blood plasma, 9-temperature-control senser, 10-calandria, 11-condensate, 12-circulating pump.
Detailed description of the invention
Blood plasma unfreezing apparatus embodiment of the present invention as shown in Figure 1, it comprises melts room 1, intensification room 4, calandria 10, condensate 11, circulating pump 12 and temperature-control senser 9, and intensification room 4 is arranged on the bottom of melting room 1; Intensification room 4 is provided with entrance 2 and outlet 3, and the entrance of intensification room 4 is connected with thawing room 1 by condensate 11, and the outlet 3 of intensification room 4 is connected with thawing room 1 by calandria 10, and described circulating pump 12 is arranged on calandria 10.Under the effect of circulating pump 12, the water of heating in intensification room 4 is entered by outlet 3, calandria 10 and melts room 1, is plasma bags heating, melts chilled water in room 1 and flows back to intensification room 4 by the entrance of condensate 11, intensification room 4, form water circulation system.
Being provided with the water temperature sensor 7 for measuring water temperature in described intensification room 4, in described thawing room 1, being provided with the blood plasma temperature sensor 8 for measure analog plasma bags internal temperature, the outfan input temperature-control senser 9 of described temperature sensor.Described water temperature sensor 7 is arranged on exit, intensification room 4.Described temperature-control senser 9 comprises micro programmable logic controller (CP1E-E30DR-A that Omron (Shanghai) Co., Ltd. produces) and touch screen (DOP-B07E515 that Taida Electronic Industry Co Ltd produces), and temperature sensor is the CP1W-TS101 that Omron (Shanghai) Co., Ltd. produces.
When the embodiment of the present invention uses, first blood plasma temperature sensor 8 is inserted in the probe pipe of simulation plasma bags 5, again simulating blood plasma bag 5 is put into together with plasma bags 6 the water heat treated of melting room 1, when the temperature that blood plasma temperature sensor 8 is measured reaches 33 DEG C, temperature-control senser 9 sends prompting, plasma bags is taken out, has thawed; When the temperature of water temperature sensor measurement 7 reaches design temperature (generally can be 42 DEG C), temperature-control senser 9 is reported to the police, close the circulating pump 12 on calandria 10, do not allow hot water continue to enter thawing room 1, thus prevent the safety affecting blood plasma because of water temperature over-high.
The temperature-control senser 9 of the embodiment of the present invention can be drawn time/temp curve and preserve, as the foundation of blood plasma unfreezing dates back, 33 DEG C of terminals thawed as thawing instrument are reached using simulating blood plasma bag core temperature, staff's heating process easy to control, can ensure safety during blood plasma unfreezing.
The embodiment of the present invention is after blood plasma unfreezing apparatus preheating is complete and heat transferring medium starts circulation, the quality management of water temperature sensor and blood plasma temperature sensing actuator temperature will be carried out, by detecting the temperature of water temperature sensor and blood plasma temperature sensor, in temperature-control senser, automatically form the difference of detected temperatures, this difference then judges 2 sensor fault-free in a certain fixed range.Ensure the effectiveness of temperature sensor.
