Description
Technical field
The present invention relates to the micro-and blood microscopic examination technical field of urine, be 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 pedestal every slide and be arranged on the upper slide on slide, wherein pedestal and upper slide are all fixed, every slide, central authorities offer opening, by pedestal, form a cavity after slide and upper slide bond together, are to detect inner chamber; On pedestal, offer and the hole of detecting inner chamber and being communicated with, these holes respectively with sample feeding pipe with go out sample pipe and be connected.Testing process is: sample liquid enters into and detects inner chamber through sample feeding pipe, then static, rely on the effect of gravity that the visible components such as cell are deposited on lower slide, make the visible components such as cell there is consistent micro objective to focal plane (as shown in Figure 2), system scans detection to the cell on lower slide afterwards, thereby obtains image clearly.Existing counting chamber detects the height of inner chamber and all fixes, about 100～200 μ m, due to highly very little and non-adjustable, detect and cleaning process in because the crystallization in sample liquid or bulky grain easily cause detecting inner chamber, stop up, thereby cannot carry out follow-up detection.
Summary of the invention
The technical problem to be solved in the present invention is to provide 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 of the present invention, comprises spring base and is placed in the pedestal on spring base, wherein:
The top of described pedestal is connected with the upper slide bearing that is bonded with slide, pedestal is built-in with the lower slide bearing that is bonded with lower slide, on this lower slide bearing, offer seal groove, in seal groove, be provided with " O " RunddichtringO, described lower slide is provided with at least two locating pieces, on it, also offer sample holes, this sample holes is connected with sample feeding pipe;
On spring base, offer several blind holes, blind hole is built-in with spring;
Between described pedestal and spring base, by tie down screw, connect, now, the bottom of lower slide bearing is pressed on the spring on spring base, between described upper slide and lower slide, forms a cavity, for detecting inner chamber.
In technique scheme,
The thickness of described locating piece had better not be less than the diameter of the visible components such as cell in sample liquid, and the thickness of locating piece is advisable with 10～20 μ m conventionally.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 lower slide in bonding mode conventionally, and the bonding location of locating piece is generally the marginal position near lower slide.
In order to make spring top on spring base and the bottom of lower slide bearing have larger surface of contact, preferably the blind hole on spring base is opened in to the orthogonal projection below of lower slide bearing.
In technique scheme, described upper slide bearing can adopt and removably connect with being connected also of pedestal, just now needed with tie down screw, upper slide bearing, pedestal and spring base three to be coupled together.
Compared with prior art, streaming counting of the present invention pond, upper slide is fixed on upper slide bearing, and lower slide is fixed on the lower slide bearing in pedestal, when with tie down screw, by pedestal and spring base, the two is connected, the bottom of lower slide bearing is pressed on the spring on spring base, therefore, can be by adjusting tie down screw or by regulating the pressure of sample introduction liquid (or cleaning fluid) to obtain in lower slide, on outer pressure differential realizes and increases or reduce, distance between lower slide, realize by upper, the adjustable object of thickness of the detection inner chamber that lower slide forms, and then realization is difficult for causing detecting the object that inner chamber stops up in detection and cleaning process.In addition, when detecting, adjust the thickness that detects inner chamber, make it in minimum thickness, at sample liquid, be full of after whole detection inner chamber, in sample liquid, the visible component such as cell is just equivalent to be fixed in microscopical focusing aspect, although this up-to-date style liquid is flowing, but for microscope, be not affect to carry out clear detection counting, therefore, be equivalent to realize the quick location of sample; And after the thickness that detects inner chamber is increased, be particularly conducive to cleaning, can effectively avoid detecting the phenomenon generation that inner chamber stops up.
