Abstract
The utility model relates to a syringe structure of blood cell analyzers, which comprises an O-shaped sealing ring, a piston column and an external cylinder of a syringe, wherein, the O-shaped sealing ring is positioned in a groove of the piston column. A teflon sleeve covers the piston column and the O-shaped sealing ring, and the teflon sleeve and the piston column are enclosed into a whole through screw threads and a locking nut, wherein, the screw threads are positioned at the front end of an inserting member of a piston. After installation, the outer wall of a teflon outer sleeve and the inner wall of the external cylinder of the syringe are squeezed up by the elasticity generated by the O-shaped sealing ring being pressed in order to reach the aim of sealing. The syringe of the utility model has the advantages of abrasion resistance and self-lubricity, and therefore, the sealing life of the syringe is prolonged.
Description
Technical field
The utility model relates to blood-counter system, relates in particular to the piston type syringe hermetically-sealed construction of cellanalyzer.
Background technology
Syringe must have good sealing property as the hydrodynamic source of blood-counter system, to prevent the leakage of reagent.Its sealing of conventional injector all is to adopt rubber seal, and its material is had relatively high expectations, even like this, also be easy to because of wearing and tearing produce leakage, and the also easy contamination reagent of damaged rubber.Generally after moving several ten thousand times, just must change O-ring seal, make troubles for user's use.
Summary of the invention
The purpose of this utility model is at the deficiencies in the prior art, provide a kind of have not easy to wear, the syringe construction of the cellanalyzer of long service life.
The purpose of this utility model is realized by following technical scheme:
The utility model comprises the O RunddichtringO, teflon cover, piston boit, syringe urceolus.The O RunddichtringO is arranged in the groove of piston boit, the teflon cover entangles piston boit and O RunddichtringO, and the teflon cover being surrounded an integral body with piston boit by the screw thread of piston plug-in unit front end and set nut, the external diameter at O type circle place is slightly larger than the internal diameter of syringe urceolus after the moulding.Elasticity after the installation back is extruded by the O RunddichtringO reaches the purpose of sealing with the outer wall of teflon overcoat and the inwall jam-packed of syringe urceolus.
The utility model has designed a kind of teflon overcoat, is used with the conventional seals circle.Make its elasticity that had both had rubber, have wearing quality and self lubricity again, syringe is improved sealing life greatly.Surpass more than 1,000,000 times serviceable life.

Embodiment
Fig. 1 is the utility model embodiment, it is by O RunddichtringO 1, teflon cover 3, piston boit 2, syringe urceolus 6 is formed, and O RunddichtringO 1 is in the groove of piston boit 2, and teflon cover 3 entangles piston boit 2 and O RunddichtringO 1, and teflon cover 3 being surrounded an integral body with piston boit 2 by the screw thread of piston plug-in unit 5 front ends and set nut 4, the external diameter at O type circle 1 place is slightly larger than the internal diameter of syringe urceolus 6 after the moulding.Elasticity after the installation back is extruded by O RunddichtringO 1 reaches the purpose of sealing with the outer wall of teflon overcoat 3 and the inwall jam-packed of syringe urceolus 6.
Claims (1)
1, a kind of piston type syringe hermetically-sealed construction of cellanalyzer, comprise the O RunddichtringO, piston boit, the syringe urceolus, it is characterized in that: the O RunddichtringO is arranged in the groove of piston boit, the teflon cover entangles piston boit and O RunddichtringO, and the teflon cover is surrounded an integral body with piston boit by the screw thread of piston plug-in unit front end and set nut, the external diameter at O type circle place is slightly larger than the internal diameter of syringe urceolus after the moulding, elasticity after the installation back is extruded by the O RunddichtringO seals the outer wall of teflon overcoat and the inwall jam-packed of syringe urceolus.
