Description
Technical field
The utility model relates to medical instruments field, in particular to a kind of safety type blood-taking needle.
Background technique
Blood taking needle is detected for acquiring Human Blood for chemical examination, or acquisition blood of human body storage is used for transfusion requirement.Mesh
The preceding blood taking needle generally used is arranged with sheath on the needle stand of blood taking needle, screens to syringe needle formation, the needle point of blood taking needle is avoided to exist
Bending deforms due to collision in storage, transportational process.When using blood taking needle, sheath need to remove to exposed needle, acquire blood sample or
After blood, syringe needle is transferred to from patient's body, on the needle stand for needing for sheath to be set in blood taking needle again, to avoid processing needle
Head during cause needle to stab personnel, however, due to sheath is small in size, particularly sheath correspond to syringe needle aperture it is smaller, cure
For shield personnel during being arranged sheath again, the syringe needle after use easily causes needle to stab medical staff, causes medical care people
The serious consequences such as member's infection.
Summary of the invention
The purpose of this utility model is in view of the deficiencies of the prior art, to provide a kind of safety type blood-taking needle, structure is simple,

The rear end of seat is fixed with hose, and syringe needle is connected with hose, and the free end of hose is equipped with for connecting with blood taking bag or heparin tube
The connector connect, be slidably matched on the needle stand sheath, and the length of the sheath is greater than the sum of syringe needle and the length of needle stand, described
The side wall of sheath is equipped with the limit strip-shaped hole extended along length direction, and the needle handle passes through the limit strip-shaped hole, limits
Sheath is moved to towards needle point covers syringe needle, or limits sheath and be moved to exposed needle towards needle stand.
The sheath is made of transparent plastic.
The side wall of the sheath is equipped with sheath handle, and sheath handle and limit strip-shaped hole are located at the two sides of sheath.
The sheath handle is equipped with several lightening holes.
The sheath handle and sheath are made up of integrated injection molding.
The sheath is made of hose.
For the sheath empty set on needle stand, the needle handle passes through the limit strip-shaped hole on sheath, and sliding with limit strip-shaped hole
Dynamic cooperation.
The sheath is slidably fitted on needle stand, the needle handle pass through sheath on limit strip-shaped hole, and with limit bar shaped
Interporal lacuna cooperation.
It has the advantages that by adopting the above technical scheme
1, be slidably matched a sheath on needle stand, and the length of the sheath is greater than the sum of syringe needle and the length of needle stand, the sheath
Side wall be equipped with the limit strip-shaped hole that extends along length direction, the needle handle passes through the limit strip-shaped hole, restriction sheath
It is moved to towards needle point and covers syringe needle, or limited sheath and be moved to exposed needle towards needle stand, strip-shaped hole is limited by setting
And sliding position is limited by needle handle, both facilitate sliding sheath to cover to designated position or exposed needle, also can effectively prevent sheath
It falls off.When original state, sheath is located at the top of needle stand, covers syringe needle, is formed and is protected to syringe needle, avoids syringe needle in storage, fortune
It is defeated during needle point deformed because of collision lead to not using, also avoid medical staff take blood taking needle when stabbed by needle, when
When sheath slides into the thorough exposed needle in needle stand bottom, blood was collected sample or blood sampling, blood-sample withdrawal or blood are used for medical staff
After liquid, medical staff is slid into sheath again at the top of needle stand, syringe needle of screening, after avoiding traditional blood taking needle use
It is easy to happen needle when being arranged sheath and stabs the fortuitous event for leading to infection, effectively avoids the generation that needle is stabbed in active procedure.
It is simple, easy to assembly that the utility model is slidably fitted in the jacket structure on needle stand, also has the advantages that preparation cost is low.
2, sheath is made of transparent plastic, observes syringe needle situation convenient for medical staff.
3, the side wall of sheath is equipped with sheath handle, and sheath handle and limit strip-shaped hole are located at the two sides of sheath, doctor
Shield personnel push sheath to slide axially along needle stand by sheath handle, more convenient to use.
4, the sheath empty set is on needle stand, and the needle handle passes through the limit strip-shaped hole on sheath, and with limit strip-shaped hole
Be slidably matched or the sheath be slidably fitted on needle stand, the needle handle pass through sheath on limit strip-shaped hole, and with limit
Strip-shaped hole clearance fit, by or needle stand is slidably matched with sheath or the limit strip-shaped hole of needle handle and sheath is slidably matched, make to protect
There is resistance when covering opposite needle stand sliding, prevent sheath free to slide on needle stand, be held in designated position.
It is further described with reference to the accompanying drawings and detailed description.
Detailed description of the invention
Fig. 1 is the structural schematic diagram that the utility model syringe needle covers；
Fig. 2 is the structural schematic diagram of the utility model syringe needle exposure.
In attached drawing, 1 is needle stand, and 2 be needle handle, and 3 be syringe needle, and 4 be hose, and 5 be connector, and 6 be sheath, and 7 be limit bar shaped
Hole, 8 be sheath handle.
Specific embodiment
It referring to Fig. 1 and Fig. 2, is a kind of specific embodiment of safety type blood-taking needle.Safety type blood-taking needle includes needle stand 1, needle
