Abstract
The invention discloses a kind of anti-aculeus blood-taking needles, including needle body, needle stand, needle cap and conduit, and the sheath of tubulose, the needle body is fixed on needle stand, needle cap wrap up needle body and with the removable connection of needle stand, the conduit is connected to by needle stand with needle body, and the sheath is coaxial with needle body, needle stand, internal screw thread is equipped in the sheath, the needle stand outer wall is equipped with external screw thread compatible with sheath.Anti- aculeus blood-taking needle disclosed by the invention, its sheath for being additionally arranged tubulose, so that blood taking needle wraps up needle body without giving needle cap for change after use again, but knob sheath can be passed through, keep its side outside needle stand mobile to needle body outside, needle body finally is enclosed, effectively prevent discarded blood taking needle secondary pollution.
Description
Technical field
The present invention relates to technical field of medical equipment, in particular to a kind of anti-aculeus blood-taking needle.
Background technique
Vacuum blood collector is made of vacuum blood collection tube and blood taking needle, and blood taking needle includes needle body, needle stand and needle cap, and needle body is solid
Due on needle stand, needle cap wrap up needle body and with the removable connection of needle stand.Divide completely with needle body, needle stand after being removed due to needle cap
From, it is easy to it can lose, therefore the blood taking needle discarded after use is essentially all exposed needle body, subsequent collection, transport
In treatment process, medical staff and related operator will be scratched by being not careful syringe needle.
Summary of the invention
Anti- aculeus blood-taking needle provided by the invention has additional sheath on needle stand, and sheath can be finished in blood taking needle use
After move forward, avoid needle body exposed, prevent discarded blood taking needle from injuring treatment people.
A kind of anti-aculeus blood-taking needle, including the sheath of needle body, needle stand, needle cap and conduit and tubulose, the needle body are fixed
In on needle stand, needle cap wrap up needle body and with the removable connection of needle stand, the conduit is connected to by needle stand with needle body, the shield
Set is coaxial with needle body, needle stand, and internal screw thread is equipped in the sheath, and the needle stand outer wall is equipped with external screw thread compatible with sheath.
Further, the sheath is equipped with cricoid bottom wall, and the internal screw thread is set to the inside of the through-hole on bottom wall, the needle
Seat is equipped with the limited block for stopping sheath bottom wall with needle body junction.
Further, the outer wall of the sheath is equipped with vertical skid resistance strip.
Anti- aculeus blood-taking needle disclosed by the invention, is additionally arranged the sheath of tubulose, so that blood taking needle nothing after use
Needle cap need to be given for change and wrap up needle body again, but can be by knob sheath, making it, side is to movement on the outside of needle body outside needle stand, finally
Needle body is enclosed, discarded blood taking needle secondary pollution is effectively prevent.
Detailed description of the invention
To describe the technical solutions in the embodiments of the present invention more clearly, make required in being described below to embodiment
Attached drawing is briefly described.Obviously, described attached drawing is a part of the embodiments of the present invention, rather than is all implemented
Example, those skilled in the art without creative efforts, can also be obtained according to these attached drawings other designs
Scheme and attached drawing.
Fig. 1 is the structural schematic diagram before the anti-aculeus blood-taking needle use；
Fig. 2 is the structural schematic diagram after the anti-aculeus blood-taking needle use.
Specific embodiment
It is carried out below with reference to technical effect of the embodiment and attached drawing to design of the invention, specific structure and generation clear
Chu is fully described by, to be completely understood by the purpose of the present invention, feature and effect.Obviously, described embodiment is this hair

Connection/connection relationship not singly refers to that component directly connects, and referring to can be according to specific implementation situation, by adding or reducing connection
Auxiliary is connect, to form more preferably coupling structure.Each technical characteristic in the invention, in the premise of not conflicting conflict
Under can be with combination of interactions.
As illustrated in fig. 1 and 2, a kind of anti-aculeus blood-taking needle, including needle body 1, needle stand 2, needle cap 3 and conduit 4 and tubulose
Sheath 5, the needle body 1 are fixed on needle stand 2, needle cap 3 wrap up needle body 1 and with the removable connection of needle stand 2, the conduit 4
It is connected to by needle stand 2 with needle body 1, the sheath 5 is coaxial with needle body 1, needle stand 2, is equipped with internal screw thread, the needle in the sheath 5
2 outer walls of seat are equipped with external screw thread compatible with sheath 5.
As further preferred embodiment, the sheath 5 is equipped with cricoid bottom wall 51, and the internal screw thread is set to bottom wall
The inside of through-hole on 51, the needle stand 2 are equipped with the limited block 21 for stopping bottom wall 51 with 1 junction of needle body.
As further preferred embodiment, the outer wall of the sheath 5 is equipped with vertical skid resistance strip.
Better embodiment of the invention is illustrated above, but the invention is not limited to the implementation
Example, those skilled in the art can also make various equivalent modifications on the premise of without prejudice to spirit of the invention or replace
It changes, these equivalent variation or replacement are all included in the scope defined by the claims of the present application.
