Abstract
The utility model relates to pathological medical equipments, particularly relates to medical apparatus and instruments for preparing thin-wall cell sheets and in particular relates to a needle tube set for a tabletting machine. The needle tube set comprises a liquid outlet needle tube and a liquid absorbing needle tube, wherein the needle head of the liquid absorbing needle tube is bent for a certain degree a, and the needle head of the liquid outlet needle tube is formed in a manner that a bending pipe I, a bending pipe II and a bending pipe III are combined. According to the needle tube set for the tabletting machine, the needle head is subjected to bending processing, the flow rate of liquid in the liquid outlet needle tube is controlled, the liquid outlet direction forms a certain angle with a bottom glass slide, and the cell is avoided from being damaged; and the residual liquid can be completely absorbed by the liquid absorbing needle tube through a bending angle and an inclined end face of a needle tip, and the quality of tabletting is improved.
Description
Technical field
The utility model relates to the pathology medical supply, in particular for the medicine equipment of the pelleter of making the thin-layer cell smear, specifically a kind of needle tubing group for pelleter.
Background technology
At present, scientific research institution adopts the mode of making cell smear dyeing to come observation of cell to form mostly, better understands biological nature.Existing dyeing needle tubing for cell preparation staining machine is vertical shape, because it is less that the dye liquor in the Dyeing pipe of vertical shape is subject to the resistance of Dyeing pipe inwall, splash into the surface that directly to beat when being subjected to liquid container at microslide from needle tubing, when dyeing, may break up cell like this, come off.Simultaneously, again because the fluid resistance of the Dyeing pipe of dyeing pin is smaller, so easily produce the problem of hanging drop.Therefore, need a kind of flow rate of liquid that can allow reduce, and the needle tubing that sprays at an angle, and unnecessary liquid can be siphoned away simultaneously, be suitable for the special-purpose needle tubing of automated cell pelleter.
Summary of the invention
The purpose of this utility model is exactly the problem that exists for solving prior art, for the actual needs of full-automatic thin cell specimen preparing machine, and has designed a kind of needle tubing group for pelleter.
The technical solution of the utility model is: a kind of needle tubing group for pelleter includes fluid needle tubing and imbibition needle tubing, the crooked certain angle a of the syringe needle of described imbibition needle tubing, 10 °＜a＜20 °; The syringe needle of described fluid needle tubing is combined by three sections of bending tube I, bending tube II, bending tube III successively, fluid needle tubing and bending tube I angle are b, bending tube I and bending tube II angle are b, and bending tube II and bending tube III angle are b, wherein 25 °＜b＜35 °; Described angle b is all in same plane, and bending tube II is parallel with the fluid needle tubing.
The needle tubing mouth of pipe end face of described imbibition needle tubing, fluid needle tubing and mouth of pipe xsect all are 30 ° of angles.
Described needle tubing group comprises four fluid needle tubings and an imbibition needle tubing.
The mouth of pipe of described imbibition needle tubing and fluid needle tubing is on the surface level of sustained height, and is being 45 ° of angles on the surface level of the mouth of pipe between the fluid needle tubing, is 90 ° of angles between fluid needle tubing and the imbibition needle tubing.
The beneficial effects of the utility model can draw by such scheme, because syringe needle is carried out bending process, flow rate of liquid in the fluid needle tubing is controlled, and the fluid direction of liquid and bottom microslide avoid damaging cell (avoiding dye liquor to break up pathological cells) at an angle.The imbibition needle tubing is by crooked angle, and the angled end-face of needle point, can with remaining liq (fully) exhaustion, improve the quality of film-making.Can draw thus, the utlity model has certain progressive and practicality, very large popularizing value is arranged.
