Abstract
A blood corpuscle analyzing sensing device relates to a sensing component of a blood detecting analyzer, which belongs to the medical treatment appliance technical field. The gem hole of the present sensing device is often blocked, while the sensing device cleans only the inside of the gem hole but not the outside, thereby the outside gathers more stems. The blood samples which pass through the gem hole return in large circuitous space, which causes interference to the detecting precision of small particles of platelets. The utility model adds a filter, equips a gem window in a straight canula with a small internal diameter, leads the cleaning fluid from one side of the gem window and discharges it from the other side. The above measures overcome the shortcomings of the prior arts of blocking gem window, incomplete cleaning, blood samples returning or the like, thereby the utility model can be applied in the fields of blood corpuscle detecting and analyzing instruments.
Description
Technical field
The utility model is the sensing element in a kind of haemocyte check and analysis instrument, is the important component part of cellanalyzer, belongs to technical field of medical instruments.
Background technology
The sensing element that present cellanalyzer is adopted can be recognized from the employed instrument of medical institutions.In addition, by publish People's Health Publisher in March, 1997, the 311st～315 page of " medical testing instruments principle is used and maintenance " (second edition) book of Li Zujiang chief editor also introduce this technology, see shown in Figure 1ly, this sensing device is made up of sample cup 1, aperture pipe 2, anode 3, negative electrode 4, constant current source 5, negative pressure pump 6, waste liquid bottle 7, bottle for handling liquid toilet or cosmetic substance 8, valve 9 and each conduit.Aperture pipe 2 lower ends are angled end-face 10, see shown in Figure 2ly, and the position is inlaid with jewel window 11 therebetween, is made by ruby or sapphire, and the heart has jewel hole 12 therein, and diameter is between 60～100 microns.Blood sample is accurately diluted with physiological saline in sample cup 1, provide 0.5 milliampere steady current by constant current source 5, this electric current forms the loop between the physiological saline in anode 3, negative electrode 4 and the jewel hole 12 of flowing through.In testing process, valve 9 is closed, under the effect of negative pressure pump 6, red blood cell in the blood sample, leucocyte, blood platelet are pressed path flow shown in the solid arrow with salt solution, promptly enter aperture pipe 2 by jewel hole 12, enter waste liquid bottle 7 along conduit, in this course, sensing device is drawn the blood sample of the amount of determining.Because red blood cell, leucocyte, hematoblastic granularity are respectively 6～9,7～15,2～3 microns, approaching with the aperture number magnitude in jewel hole 12, at each red blood cell, leucocyte, blood platelet during by jewel hole 12, the capital causes that loop resistance changes, and, this variation that the three causes is obviously different, so, positive pole at constant current source 5 can extract this variable signal, can calculate red blood cell, leucocyte, hematoblastic quantity in the blood sample unit volume (microlitre) according to this signal, through further analyzing, health status is made judgement.Before detecting next blood sample, Open valve 9, under the effect of negative pressure pump 6, the cleaning fluid in the bottle for handling liquid toilet or cosmetic substance 8 is pressed path flow shown in the dotted arrow, promptly enters aperture pipe 2 through valve 9, conduit, enters waste liquid bottle 7 along another conduit behind impact angled end-face 10 inwalls.This process can be finished the cleaning to aperture pipe 2 lower ends, avoids the interference of raffinate to testing result; Can also clean jewel hole 12, in order to avoid stop up.
Summary of the invention
The design people thinks that above-mentioned known technology comes with some shortcomings, and mainly shows, at first, owing to contain many " impurity " in the blood sample, the blood sample of filtered often stops up jewel hole 12; Secondly, the cleaning of this sensing element is only carried out at 12 inboards, jewel hole, fail to clean to its outside, and the tamper that assemble in the outside is more; The 3rd, the internal diameter of the aperture pipe 2 in this sensing element is bigger, be generally 6 millimeters, the subordinate holds and forms a bigger circuitous space within it, the blood sample that enters aperture pipe 2 from jewel hole 12 backflows in this space, also can produce bubble in this space, these phenomenons cause interference to the less hematoblastic accuracy of detection of granularity.In order to overcome the deficiency of above-mentioned known technology, we have designed a kind of cellanalyzer sensing device.
The utility model be achieved in that see shown in Figure 3, it by sample cup 13, filtrator 14, jewel window 15, negative pressure pump 16, waste liquid bottle 17, constant current source 18, anode 19, negative electrode 20, valve 21, isolate drop bottle 22 and each section conduit is formed.Filtrator 14 is between sample cup 13 and the jewel window 15; Jewel window 15 is installed in the conduit; Anode 19, negative electrode 20 are electrically conductive conduits, and their end is placed in jewel window 15 both sides respectively; Their other end is connected by insulated conduit, valve 21, isolation drop bottle 22, forms fluid path.
Owing to adopt filtrator 14, the blood sample that obtains through accurately diluting (is being seen shown in Figure 4) before certainly the sample cup 13 that holds this blood sample to jewel hole 23, the impurity overwhelming majority wherein is by these filtrator 14 filterings, thereby eliminated the latch up phenomenon in jewel hole 23 basically.Valve-off 21, under the effect of negative pressure pump 16, the blood sample jewel hole 23 of flowing through realizes detecting, and sees shown in the solid arrow among Fig. 3; Afterwards, after residue blood sample eliminating wherein, sample cup 13 double as washing lotion cups, promptly to wherein adding cleaning fluid, Open valve 21, under the effect of negative pressure pump 16, wash liquid stream in the sample cup 13 is through conduit, filtrator 14, wash away a side of jewel window 15, the negative electrode 20 of flowing through again, valve 21, isolate drop bottle 22, behind the anode 19, wash away the opposite side of jewel window 15, enter waste liquid bottle 17 at last, see shown in the dotted arrow among Fig. 3, this process has not only been finished sample cup 13, filtrator 14 and both sides conduit thereof, negative electrode 20, the cleaning of the conduit of jewel window 15 present positions etc., eliminated the interference of raffinate, also cleaned the both sides of jewel window 15 simultaneously, thereby further eliminated the latch up phenomenon in jewel hole 23 next blood examination result.Because blood sample still keeps the craspedodrome state after by jewel hole 23 in testing process, and be to advance in the comparatively narrow and small conduit in space, the internal diameter of this conduit only has 2～3 millimeters, so, basically eliminate the phenomenon of backflowing of blood sample, thereby improved hematoblastic accuracy of detection greatly.Isolate the employing of drop bottle 22, avoided because the short circuit of the generation between constant current source 18 that causes because of liquid that the structure of the sensing element of the utility model causes.
