Description
The utility model relates to medical capillary viscosimeter, particularly relates to medical automatic capillary viscosimeter.
Measure the existing long history of viscosity of solution with capillary viscosimeter.In medical treatment, the principle of this viscosity meter more approaches the blood of human body mobility status, and is simple to operate, is applicable to that clinical labororatory uses.The simplest capillary viscosimeter is to utilize the gravity of fluid to be measured itself as driving pressure differential, and as the timing conductor, the shortcoming of this viscosity meter is that pressure reduction is little and non-constant, non-adjustable with test solution, and kapillary very easily stops up, the poor repeatability of measurement result.
Institute of medical instruments and apparatus, Beijing discloses a kind of adjustable constant voltage capillary viscosimeter (application number 85202964) and has been called the adjustable constant voltage capillary viscosimeter of WTP-BII type, pressure reduction parts to general in the world Coulter viscosity meter have been done improvement, replaced three the glass ground joint valves and the complicated glazing channel of former machine with single ground threeway, and utilized rubber balloon to replace the electronic negative pressure source of bleeding for positive pressure source.Figure l shows the adjustable constant voltage capillary viscosimeter of WTP-BII type schematic diagram.This viscosity meter constant pressure, adjustable size can be surveyed, and repeatability is better.But this viscosity meter in use, and blood preparation directly enters in the mercury reservoir, very fast generation chemical reaction, cause the staff every day all will be with cleaning mercury for a long time, both elapsed times, as easy as rolling off a log again generation mercury poisoning accident, thus influenced the service efficiency and the social benefit of this machine.
The purpose of this utility model provides a kind of automatic capillary viscosimeter, simplifies the operation, and improves the automaticity of instrument.
Another purpose of the present utility model is to improve working conditions, and reduces the generation of mercury poisoning incident, guarantees personal safety.
Another purpose of the present utility model is the function that increases capillary viscosimeter, both can measure high shear rate, can measure low shear rate again.
According to the utility model, set up a sample suction port at the inlet end capillaceous of transferring the constant voltage capillary viscosimeter, connect three glass stop,threeways continuously at endpiece capillaceous, one is used to select high shear rate and low shear rate to measure channel selecting, another pressure that is used for high shear rate and low shear rate measurement is selected, the 3rd pivot button that is used as drainage, preparation, work, cleaning.Set up a waste liquid waste pipe, this waste pipe is the waste liquid waste pipe, is again the source of power, in the discharging waste liquid, mercury slug is risen automatically, recovers potential energy, produces drive pressure.
According to the utility model, symmetrical with former mercury reservoir, timing electrode, set up mercury reservoir and timekeeping system that a cover is used to measure low shear rate, be used to finish the low shear rate measurement function.
According to the utility model, set up flushing pipe, in order to realize washing automatically capillary system, improve automaticity, the chance of the direct contact water silver that reduces a staff reduces the generation of the heavy malicious accident of mercury, guarantees personal safety.
According to automatic capillary viscosimeter of the present utility model, prevented that in operating process blood from directly entering in the mercury reservoir, thereby avoided blood contamination mercury, therefore can clean mercury every day, broken away from the danger of mercury poisoning.
Another advantage of the utility model is to have realized that instrument boosts, inhales sample, timing, cleaning process robotization, has simplified operation significantly, has improved work efficiency.
Another advantage of the present utility model is both can do high shear rate, can do low shear rate again.
Last advantage of the present utility model is the repeatability that has increased measurement result.
Below in conjunction with accompanying drawing the utility model is elaborated.
Fig. 1 is the adjustable constant voltage capillary viscosimeter schematic diagram according to CN85202946.
Fig. 2 is the automatic capillary viscosimeter schematic diagram of the utility model.
As shown in Figure 1, blood sample to be measured inserted in the liquid storage tank 1 rotates glass threeway ground piston 4, waste liquid pool 3 and mercury reservoir 5 are communicated, manual pressuring gasbag 6, with the mercury liquid level pressure drop in the mercury tube to the A place, to produce driving pressure differential.Rotate threeway ground piston 4 again, mercury reservoir is communicated with kapillary 2.This moment is the venting capsule manually, and mercury picks up counting when flowing to the B place by A, stops timing when flowing to the C place, and mercury restores balance then, measures and finishes.Meanwhile, blood enters in the mercury reservoir 5 through kapillary and connecting pipe thereof.Waste liquid in the manual drain waste liquid pool 3 manually cleans kapillary 2 then, manually cleans the mercury in the mercury reservoir 5.
As shown in Figure 2, a sample suction port 7 is connected on the inlet end of kapillary 2, two other joint of glass stop,threeway 8 on the endpiece of kapillary 2 connects a waste liquid separator tube 9 and a waste liquid waste pipe 13 respectively, the lower end of this waste liquid waste pipe 13 connects another glass stop,threeway 10, two other joint of this stop,threeway 10 connects respectively and low hobs solenoid and height hobs solenoid, and the upper end of waste liquid separator tube 9 connects another glass stop,threeway 11, two other joint of this glass stop,threeway 11 connects two other glass stop,threeway 4 respectively, 4 ', one of them glass stop,threeway 4 connects flushing pipe 12, mercury reservoir 5, together with the timing electrode A, B, C forms the high shear rate of capillary viscosimeter and measures the loop, wherein another glass stop,threeway 4 ' connection flushing pipe 12 ', mercury reservoir 5 ', together with the timing electrode A ', B ', the low shear rate of C ' formation capillary viscosimeter is measured the loop.
The operating process of this automatic capillary viscosimeter is: desire to do high shear rate and measure, rotate two glass stop,threeways 4 and 11, mercury reservoir 5 and waste liquid separator tube 9 are communicated.Rotate threeway glass piston 8 again, waste liquid separator tube 9 and discharging of waste liquid pipe 13 are communicated, the interior waste liquid of waste liquid separator tube this moment flows out through discharging of waste liquid pipe 13, and the mercury liquid levels in the mercury reservoir 5 rise simultaneously, and the interior mercury liquid level of mercury tube is reduced to the A place.Insert sample suction port 7 in the blood preparation this moment, rotate glass stop,threeway 8 then, kapillary 2 communicated with waste liquid separator tube 9, mercury through A, B, C restore balance and timing in, blood sample enters in the waste liquid separator tube 9 through sample suction port 7, kapillary 2, and measuring process finishes.Rotate two glass stop,threeways 4,8 this moment, and flushing pipe 12 and discharging of waste liquid pipe 13 are communicated, and rinses out the waste liquid in the waste liquid separator tube 9 automatically.Rotate glass stop,threeway 8 then, sample suction port 7 and discharging of waste liquid pipe 13 are communicated, clean the blood kapillary.So far cleaning process finishes.
