Abstract
The utility model discloses an anti-slip glass syringe which comprises a syringe cylinder, a piston push rod and a syringe needle. The inner wall of the upper portion of the syringe cylinder is provided with an annular groove, an anti-slip sealing ring matched with the annular groove is embedded in the annular groove, and the inner diameter of the anti-slip sealing ring is smaller than the outer diameter of the piston push rod. The piston push rod is matched with the syringe cylinder in a compact mode, so that the phenomenon that liquid is sucked and accordingly the piston push rod automatically slides does not occur, the situation that the syringe cylinder is unreasonably taken and placed and accordingly the piston push rod easily and automatically slides out of the syringe cylinder does not occur, and besides, the syringe cylinder can not easily slip off from hands of an operator.
Description
Technical field
This utility model relates to medical instruments technical field, particularly a kind of anticreep glass syringe.
Background technology
Be at present no matter use clinically or laboratory in the glass syringe that uses, it is to be mainly made up of syringe needle, syringe and piston push rod, this glass syringe syringe outer surface smoother, especially after surface contamination liquid, in the time injecting to patient or toy, be easy to slippage from hands, increased operator's work difficulty.
The conventional glass syringe of laboratory is to mouse stomach, because being easy to sterilization, it is convenient to reuse, but, because between piston push rod and syringe being realizes and sealing by the friction of ground glass surface, the syringe needle of glass syringe is after draw solution, due to the lubrication of solution, cause the friction of piston push rod and syringe inwall too small, the piston push rod in syringe there will be automatic downslide phenomenon.So just caused in the time of mouse stomach, gavage syringe needle does not enter solution before stomach and, because the downslide of piston push rod causes automatic outflow, therefore may cause liquid to enter in the lung of mice, finally causes dead mouse.In addition; syringe after imbibition; operator are owing to will grabbing mice; the often irrational taking and placing syringe of meeting; but at this moment the friction of piston push rod and syringe inwall is too small, air-tightness reduces, and piston push rod just easily skids off syringe automatically; cause the liquid absorbing entirely to be poured out, when piston push rod falls, also easily break.
The utility model of CN 201676352 U discloses a kind of anti-breakage glass syringe, comprise injection body, piston push rod, injection body front end has a joint, piston push rod is placed in injection body inside, also comprise a sealing cap, sealing cap is set on injection pipe joint, due to the effect of atmospheric pressure, can make the air that is trapped in syringe intracoelomic cavity in sealing state, work as transport, while having External Force Acting in cargo handling process on piston push rod, the air of syringe intracoelomic cavity can produce the effect of resisting to this external force, piston push rod and injection body just can not clash into mutually, thereby avoid glass syringe to break.But the deficiency of its existence is: syringe outer surface smoother, in the time injecting to patient or toy, is easy to slippage from hands; In use, need to remove sealing cap, syringe needle is after draw solution, due to the lubrication of solution, cause the friction of piston push rod and syringe inwall too small, the piston push rod in syringe there will be automatic downslide phenomenon, irrational taking and placing syringe, piston push rod just easily skids off syringe automatically, causes the liquid absorbing entirely to be poured out, and when piston push rod falls, also easily breaks.
Summary of the invention
The purpose of this utility model is to solve the problems referred to above that prior art exists, a kind of anticreep glass syringe is provided, between piston push rod and syringe, coordinate closely, can not there will be automatic downslide phenomenon because imbibition causes piston push rod, can be because of irrational taking and placing syringe yet, piston push rod just easily skids off syringe automatically, and syringe is difficult for slippage from operator's hands.
This utility model solves the technical scheme that its technical problem adopts:
A kind of anticreep glass syringe, comprise syringe, piston push rod and syringe needle, the inwall on described syringe top is provided with annular groove, is embedded with the anticreep sealing ring suitable with it in described annular groove, and the internal diameter of described anticreep sealing ring is less than the external diameter of described piston push rod.
By process annular groove on syringe inwall, and in annular groove setting-in anticreep sealing ring, the external diameter of anticreep sealing ring and annular groove internal diameter adaptation, the internal diameter of anticreep sealing ring is less than the external diameter of piston push rod, between anticreep sealing ring energy and piston push rod, closely cooperate like this, frictional force and sealing between piston push rod and syringe are increased, even like this after syringe imbibition, can not there will be automatic downslide phenomenon because imbibition causes piston push rod, can be because of irrational taking and placing syringe yet, piston push rod just easily skids off syringe automatically.
As preferably, the internal diameter of described anticreep sealing ring is than the little 0.5-1mm of the external diameter of described piston push rod.Rationally control the difference of the internal diameter of anticreep sealing ring and the external diameter of piston push rod, being sealed and matched so neither can be too tight and affect injection operation, also can be too not loose and do not have and effectively prevent that piston push rod from gliding, skidding off the generation of syringe phenomenon automatically.
As preferably, the part that described anticreep sealing ring exceeds syringe inwall is the arc of evagination.Such sealing anticreep effect is good.
As preferably, described annular groove arranges in pairs.By annular groove is set up and down in pairs, more stable when piston push rod is propelled like this, coordinating between syringe and piston push rod is more firm, can prevent that better piston push rod from gliding, skidding off the generation of syringe phenomenon automatically.
As preferably, described annular groove is between the highest graduation mark of syringe and the outlet of the upper end of syringe.Setting can not affect normal injection like this.
As preferably, the outer surface of described piston push rod is ground glass surface.
As preferably, described syringe is set with silica gel sheath outward.By silica gel sheath is set, silica gel sheath comfortable feel, even if be also difficult for slippage under liquid is infected with, syringe is just difficult for slippage from operator's hands like this, and silica gel sheath can play good protective action in syringe is dropped or collided, and syringe is difficult for broken.
The beneficial effects of the utility model are:
1, by process annular groove on syringe inwall, and in annular groove setting-in anticreep sealing ring, between piston push rod and syringe, coordinate closely, can not there will be automatic downslide phenomenon because imbibition causes piston push rod, can be because of irrational taking and placing syringe yet, piston push rod just easily skids off syringe automatically.
2,, by silica gel sheath is set, syringe is difficult for slippage from operator's hands, facilitates injection operation; And silica gel sheath can play good protective action in syringe is dropped or collided, syringe is difficult for broken.
