Description
Technical field
The invention belongs to technical field of medical instrument, are related to a kind of safety syringe-drum with telescopic protective cover.
Background technique
Syringe is made of dedicated PP material, and piston is made of PE material, and transparent syringe is suitable for most of fluid；Amber
Amber color syringe is suitable for UV solidification glue and optic-solidified adhesive shields wave-length coverage 240 to 550nm；Opaque black syringe can shield
There is light in covert.Every box has same amount of syringe and mating piston.The front end of syringe is used to the syringe needle that is connected, and syringe needle can be used
Medical fluid is drawn, also may be implemented to puncture, be infused patient, but after the completion of being infused, is typically only covered pinhead sleeve
It outside syringe needle, retells syringe and loses in dustbin, but when pinhead sleeve covers outside syringe needle has that noose loosely, frequently results in
Pinhead sleeve falls off, and pinhead sleeve no longer plays the role of protection to syringe needle, cause purifier arrange or clean it is used
When syringe needle, there are problems that being stabbed by syringe needle, leads to two subinfections.
Summary of the invention
The purpose of the present invention is being directed to the above-mentioned problems in the prior art, a kind of peace with telescopic protective cover is provided
Full syringe solves the safety for how improving existing syringe.
Object of the invention can be realized by the following technical scheme: a kind of safety syringe-drum with telescopic protective cover, including
The front end of cylinder and syringe needle, the cylinder has interconnecting piece, which is characterized in that and the rear end of the syringe needle is equipped with fixed part,
The front end of the fixed part is tapered, and the front end of fixed part is fixedly connected with syringe needle, and the rear end of the fixed part has solid
Determine slot, the interconnecting piece, which is inserted in fixing groove, is fixedly connected with interconnecting piece with fixed part, and the rear end of the syringe needle is inserted into
It is connected in interconnecting piece with the inner cavity of cylinder, transparent telescopic protective cover, the telescopic protective cover is cased with outside the cylinder
Bottom end and the bottom end of cylinder be fixedly connected with, the telescopic protective cover and cylinder are integral structures, the telescopic protective cover
Top there is annular retainer plate, the annular retainer plate is softer, tether is equipped in the annular retainer plate, when flexible
Protective case is when in a compressed state, is fixedly connected with annular retainer plate with cylinder by the tether tie-down, works as telescopic protective cover
When in elongation state, tighten annular retainer plate by the tether tie-down, the syringe needle is integrally located at flexible protection
In set.
Before use, in use, by tether tie-down be fixedly connected with annular retainer plate and cylinder, so that telescopic protective cover is in quilt
The state of compression, telescopic protective cover will not influence the use of syringe；After use, tether is unclamped, telescopic protective cover is elongated, makes syringe needle
Be integrally located in telescopic protective cover, then fasten tether, tighten annular retainer plate, the firmness of simultaneous retractable protective case compared with
Height cannot be pierced through by syringe needle, thus make syringe needle will not it is exposed outside, people arrange, cleaning when, will not be pricked by syringe needle,
Syringe needle will not be caused two subinfections by people, have a safety feature.
In a kind of above-mentioned safety syringe-drum with telescopic protective cover, the safety syringe-drum further includes pinhead sleeve, described
Pinhead sleeve include casing-joining part, protection portion and fastening portion, the casing-joining part is connected by protection portion with fastening portion, the set
Knot outer end is in the form of a column, and inner end is tapered, and for the protection portion in long straight tubular, the fastening portion is tapered, described
Casing-joining part with fixed part for being fixedly connected with, when the telescopic protective cover elongation pinhead sleeve is integrally located in telescopic protective cover,
It is fitted on the lateral wall of fastening portion at the top of the telescopic protective cover.Syringe needle after use, puts on pinhead sleeve, pinhead sleeve pair
Syringe needle plays the role of protection, makes syringe needle that cannot more pierce through telescopic protective cover, the setting of fastening portion, and make telescopic protective cover is
When rope is fastened, telescopic protective cover fastens pinhead sleeve, will not fall off pinhead sleeve, guarantees that syringe needle will not be contacted with the external world, will not be naked
It exposes outside, the setting of pinhead sleeve further increases the security performance of this syringe.
It is blind with being worn for syringe needle in the fastening portion in a kind of above-mentioned safety syringe-drum with telescopic protective cover
Hole.This kind of structure can reduce the length of pinhead sleeve accordingly while not influencing the protective effect of pinhead sleeve, reduce material.
In a kind of above-mentioned safety syringe-drum with telescopic protective cover, the telescopic protective cover is made of plastic material,
The telescopic protective cover is soft.Telescopic protective cover is softer, is bent telescopic protective cover more arbitrarily, makes to stretch
The better fixed pin headgear of protective case energy, enables telescopic protective cover preferably to play the role of protection.
Compared with prior art, the safety syringe-drum provided by the invention with telescopic protective cover has the advantage that
1, the telescopic protective cover of safety syringe is telescopic, achieves that flexible guarantor by fastening or unclamping tether
The compression and elongation of sheath make telescopic protective cover play the role of protection to syringe needle, while the second weight is played in the setting of pinhead sleeve
The effect of protection, make syringe needle will not it is exposed outside, improve the security performance of syringe.
2, the pinhead sleeve of safety syringe includes the tapered fastening portion of setting, and the setting of fastening portion covers pinhead sleeve in needle
It will not fall off after head is outer, stability is good, improves the security performance of syringe.
