Description
Technical field
The utility model embodiment is related to blood sample acquisition technique field, and in particular to a kind of end capillary blood sampling
Device.
Background technique
Blood assay techniques have become the important evidence of medical diagnosis on disease, especially for gene diagnosis field, more have
Very important status.End capillary blood sampling due to its blood sampling volume is few, conveniently the advantages of, be applied to micro-
Amount detection or the blood collection to child, especially blood glucose etc. monitor field.With the continuous development of medical technology, end capillary
Blood vessel blood collecting technology also can predictably be widely used in blood sample acquisition.
However, common way is that the hand-held blood taking needle of medical staff directly punctures finger finger tip, it as the saying goes that " ten refer to
Connect with the heart ", it carries out in end capillary blood collection procedure, when especially acquiring the blood sample of finger finger tip, due to adopting for medical staff
Blood gimmick is different, and often will appear cannot once puncture and need to carry out puncturing repeatedly, or punctures too deep, leads to blood donor
Moment pain is generated, the pain infiltrated caused by this moment pain makes many blood donors daunting.There is studies have shown that thorn
For 50% or more blood donor, feeling of pain is more than moderate pain for broken finger fingertip blood sampling.
Utility model content
For this purpose, the utility model embodiment provides a kind of end capillary blood-taking device, with solve in the prior art by
Puncture or puncture repeatedly in finger tip blood collection procedure it is too deep caused by blood donor's excessively pain the problem of.
To achieve the goals above, the embodiments of the present invention provides the following technical solutions:
In the first aspect of the embodiments of the present invention, a kind of end capillary blood-taking device is provided, is wrapped
Locating piece and blood taking needle are included, the blood taking needle is detachably connected the locating piece；The blood taking needle include holding rod, thread handle and
Syringe needle is punctured, described thread handle one end is detachably connected the holding rod, and the syringe needle that punctures is detachably connected the thread handle
One end far from the holding rod；Through blood sampling hole is offered on the locating piece, it is provided with external screw thread on the thread handle, institute
Thread handle is stated to be threadedly connected in the blood sampling hole.When carrying out finger tip blood sampling, after disinfection, by the locating piece and refer to face contact,
The thread handle of the blood taking needle and the blood sampling hole are spirally connected by the blood sampling hole to just finger face to pierce region at this time,
The holding rod is slowly rotated, the thread handle is mobile towards the direction close to finger face, to complete once puncturing to finger face, and
The process punctured is slow, gives blood donor's certain reaction time, reduces feeling of pain；Meanwhile the precession by controlling screw thread is long
Degree, makes to puncture depth 2mm~3mm, and avoiding puncturing too deep causes feeling of pain to enhance.
Further, in one embodiment of the utility model, the locating piece is opened away from the side of the holding rod
Equipped with slot is referred to, the section for referring to slot is arc, for fitting in skin surface.When finger tip is taken a blood sample, the finger slot of arc and finger face
Fitting, it is ensured that with face is referred to relative displacement will not occur for the locating piece, so that the blood taking needle inclination be avoided to puncture, further subtract
Feeling of pain caused by during gently puncturing.
Further, in another embodiment of the utility model, the thread handle includes clamping positioning region and the thorn that is spirally connected
Broken portion punctures syringe needle described in one end connection of the clamping positioning region, and the punctured part that is spirally connected is far from the clamping positioning region
One end connects the holding rod；The clamping positioning region punctures the total length after syringe needle is connect equal to the blood sampling hole with described
Depth, the length of the punctured part that is spirally connected are 2mm~4mm.When finger tip is taken a blood sample, by the locating piece and refer to that face paste is closed, it will be described
Clamping positioning region be installed in the blood sampling hole first, at this point, the minimum point for puncturing syringe needle just with finger face contact, slowly
The holding rod is rotated, the syringe needle that punctures slowly punctures finger face, gives blood donor's certain reaction time, reduces feeling of pain；
And it is 4mm that maximum, which punctures depth, avoiding puncturing too deep causes feeling of pain to enhance.
Further, in another embodiment of the utility model, the diameter of the punctured part that is spirally connected is less than described hold
The diameter of bar is held, in the junction formation limit blocking of be spirally connected punctured part and the holding rod.During puncturing, work as institute
The punctured part precession certain depth that is spirally connected is stated, that is, is punctured after reaching a certain level, the limit blocking prevents described be spirally connected from puncturing
Portion continues precession, prevent it is described puncture the too deep piercing of syringe needle and refer to face, bring stronger feeling of pain to blood donor.
In the further embodiment of the utility model, the diameter in the blood sampling hole is 5mm~10mm.It is enough to provide
Space, so that the blood pearl formed after puncturing is completely retained.
Further, in another embodiment of the utility model, the blood sampling hole includes spiro union portion and blood sampling portion, institute
It states spiro union portion to be threadedly coupled with the thread handle, blood sampling portion diameter is 5mm~10mm.To provide enough spaces, so that
The blood pearl formed after puncturing is completely retained, meanwhile, without limitation on the diameter of the spiro union portion.
The utility model embodiment uses above technical scheme, so that the syringe needle that punctures slowly pierces in finger tip blood sampling
Broken finger face, gives blood donor's certain reaction time, reduces feeling of pain, meanwhile, by controlling the precession length of screw thread, make to puncture
Depth is 2mm~3mm, and avoiding puncturing too deep causes feeling of pain to enhance.Finally effectively slow down in finger tip blood collection procedure, due to
Puncture or puncture repeatedly in finger tip blood collection procedure it is too deep bring irritation pain to blood donor, realize hypodynia or painless finger
End blood sampling.
