Description

Detect the adjustable streaming counting pond of inner chamber thickness

Technical field

The utility model relates to the micro-and blood microscopic examination technical field of urine, is specifically related to detect the adjustable streaming counting pond of inner chamber thickness.

Background technology

In the urinal system of existing employing streaming microscopy mode, the counting chamber structure of using as shown in Figure 1, comprise pedestal, be arranged on the pedestal every slide and be arranged on last slide on slide, wherein pedestal and last slide all are fixed, central authorities offer opening every slide, with pedestal, form a cavity every slide and the last slide back that bonds together, are to detect inner chamber; Offer and detect the hole that inner chamber is communicated with at pedestal, these holes respectively with the sample introduction pipe with go out the sample pipe and be connected.Testing process is: sample liquid enters into through the sample introduction pipe and detects inner chamber, static then, rely on the effect of gravity that visible component such as cell is deposited to down on the slide, make visible component such as cell have consistent micro objective to focal plane (as shown in Figure 2), system scans detection to the cell on the following slide afterwards, thereby obtains distinct image.Existing counting chamber detects the height of inner chamber and all fixes, about 100～200 μ m because highly very little and non-adjustable, detect and cleaning process in because the crystallization in the sample liquid or bulky grain cause detecting inner chamber easily stops up, thereby can't carry out follow-up detection.

The utility model content

The technical problems to be solved in the utility model provides a kind of adjustable streaming counting pond of detection inner chamber thickness that inner chamber stops up that is difficult for causing detecting in detection and cleaning process.

The adjustable streaming counting pond of detection inner chamber thickness described in the utility model comprises spring base and the pedestal that places on the spring base, wherein:

The top of described pedestal is connected with the last slide bearing that is bonded with slide, pedestal is built-in with the following slide bearing that is bonded with down slide, offer seal groove on this time slide bearing, be provided with " O " RunddichtringO in the seal groove, described slide down is provided with at least two locating pieces, also offer sample holes on it, this sample holes is connected with the sample introduction pipe;

Offer several blind holes at spring base, blind hole is built-in with spring;

Connect by tie down screw between described pedestal and the spring base, at this moment, the bottom of following slide bearing is pressed on the spring on the spring base, and described going up forms a cavity between slide and the play slide, be the detection inner chamber.

In the technique scheme,

The thickness of described locating piece had better not be less than the diameter of visible components such as cell in the sample liquid, and the thickness of locating piece is advisable with 10～20 μ m usually.Described locating piece can be the sheet material that other materials such as glass, copper sheet, iron plate are made, and its quantity is advisable with three.

Described locating piece is fixed on down on the slide in bonding mode usually, and the bonding location of locating piece is generally the close marginal position of slide down.

For bigger surface of contact is arranged at the bottom that makes spring top and play slide bearing on the spring base, preferably the blind hole on the spring base is opened in down below the orthogonal projection of slide bearing.

In the technique scheme, described going up being connected also can adopt and removably connecting of slide bearing and pedestal just at this moment need will be gone up slide bearing, pedestal and spring base three with tie down screw and be coupled together.

Compared with prior art, streaming counting described in the utility model pond, to go up slide is fixed on the slide bearing, and slide is fixed on the interior following slide bearing of pedestal down, when the two is connected with pedestal and spring base with tie down screw, the bottom of following slide bearing namely is pressed on the spring on the spring base, therefore, can be by regulating tie down screw or the pressure by adjusting sample introduction liquid (or cleaning fluid) to obtain down in the slide, on outer pressure differential realizes increasing or reduces, distance between the following slide, namely realize by last, the adjustable purpose of thickness of the detection inner chamber that following slide constitutes, and then be implemented in the purpose that is difficult for causing detecting the inner chamber obstruction in detection and the cleaning process.In addition, when detecting, adjust the thickness that detects inner chamber, make it to be in minimum thickness, after sample liquid was full of whole detection inner chamber, visible component such as cell just was equivalent to be fixed on the microscopical focusing aspect in the sample liquid, though this up-to-date style liquid is flowing, but for microscope, be not influence to carry out clear detection counting, therefore, be equivalent to realize the quick location of sample; And after the thickness that will detect inner chamber increases, be particularly conducive to cleaning, can effectively avoid detecting the inner chamber phenomenon of blocking and take place.
