Abstract

The utility model discloses a counting pool for the conventional medical examination of human fecaluria. The technique of the utility model is mainly characterized in that one counting chamber (4) communicated with pipelines (8) and (9) is arranged. When negative pressure is enforced on the end of the pipeline (9), a specimen can be automatically charged into the counting chamber to be examined by a microscope from the pipeline (8). The utility model is used in the routine examination of the human fecaluria, effectively solving the problem that current smearing method is of complicated operation, low result precision and frequent error occurrence.

Description

Automatic liquor-flushing counting pond

This utility model relates to a kind of specimen automatic liquid feeding that makes in the medical test of fecaluria specimen, for the counting chamber of microscopy.

In the fecaluria routine inspection in medical science, check visible components such as wherein erythrocyte, leukocyte, worm's ovum, cast, though can carry out quantitative check to it with the blood count pond, this kind method will be handed glass rod filling specimen, and also there is certain difficulty in the Cleaning count pond.Therefore, general fecaluria microscopy is to put test under microscope behind the manual smear of specimen.But because of plate coating thickness is a unknown number, so this method can only be done qualitative report to the result.

The purpose of this utility model is that a kind of improved counting chamber will be provided, and it can overcome the shortcoming of present smear, has promptly both cancelled fussy hand operation, has improved the precision of check again.

The purpose of this utility model is achieved in that and sticks into the blood count pond closed, and draw two pipelines at counting chamber two openings, after so at one end pipeline opening is given negative pressure, other holds the pipeline skewer to go in the liquid sample, (for to match with this utility model, I have designed the faecal specimen harvester simultaneously, the faecal specimen that it is gathered can use when counting for this utility model, ask for an interview my 89204785.2 patent applications about its details), specimen can charge into counting chamber automatically, and then the trier can test to the specimen in the counting chamber by microscope.Automatically the specific practice towards the liquid counting chamber is: each makes a call to hole, garden (2), (3) of a diameter through long 33 mm of 1.2mm at the two ends of the poly (methyl methacrylate) plate (1) of 75 * 25 * 3.5mm in (1) elder generation, thereafter making a call to two again is that 8mm, diameter are two vertical cores (10), (11) of 1.2mm perpendicular to the upper surface spacing, and it is communicated with two cross-drilled holes respectively.(2) will dig out the slotted hole of one 8 * 1.2mm in the middle of the film of one 20 * 25 * 0.3mm, and it be bonded on (1), make hole (8), (9) therewith slotted hole communicate.(3) go up the coverslip of sticking-20 * 15 * 0.1mm again in (5).

This utility model is because the volume of counting chamber is a definite value, thus can do quantitative report to the microscopy result, and the smear method of use is a unknown number because of plate coating thickness at present, so the result only can do qualitative report; Smear method is usually too thick because of smear, and makes specimen be sticky with the high power lens camera lens when the conversion of camera lens, and specimen thickness of the present utility model is in the operating distance of high power lens, so above phenomenon can not take place; This utility model is owing to be automatic liquid feeding, the trouble of having saved smear and having developed a film; Another bigger advantage of this utility model is that according to preliminary experiment, 50 parts of specimen of smear method microscopy are used 2.5 hours approximately, and only use 1 hour with this utility model fast.

The concrete structure of utility model is provided by following examples and accompanying drawing thereof.

Fig. 1 is the profile according to the counting chamber that the utility model proposes.

Describe automatic details and the working condition that the utility model proposes in detail towards the liquid counting chamber below in conjunction with Fig. 1:

This counting chamber comprises a counting chamber main body (1), and two cross-drilled holes (2), (3) are arranged in the main body (1), has vertical core (10) and (2) to join again, and vertical core (11) joins with (3).(2), (3) communicate with counting chamber (4) respectively, (4) are by main body (1) and pad (5) and bonding the forming of cover plate (7).

After pipe (9) end that joins with (2) is given a negative pressure (this negative pressure forms with motor extruding silica gel tube), pipe (8) skewer is gone into specimen, because (8) communicate with (3),, specimen is sucked or the extraction counting chamber by the control negative pressure source so specimen can charge into counting chamber automatically.

Claims

1, towards the liquid counting chamber one counting chamber (4) is arranged automatically, it is characterized in that (4) are by main body (1) pad (5), bonding the forming of cover plate (7), counting chamber (4) by hole (10), (11), (2), (3) respectively and pipeline (8), (9) communicate.

2,, it is characterized in that cover plate (7) thickness should be at 0.1～0.5mm according to the described device of claim 1

3,, it is characterized in that pad (5) thickness should be at 0.3～0.5mm according to the described device of claim 1.
