Description
Technical field
The utility model embodiment is related to blood sample acquisition technique field, and in particular to a kind of finger tip blood-taking 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, the common way of existing capillary blood sampling is that medical staff holds blood taking needle directly to finger finger tip
It is punctured, as the saying goes " so closely linked with one's heart ", carried out in end capillary blood collection procedure, especially acquire the blood sample of finger finger tip
When, in the moment that blood taking needle punctures, blood donor can be made to generate moment pain, it is this to keenly feel possibly even beyond intermediate pain, this
When blood donor due to conditioned reflex, can fast retractile arm, if at this moment syringe needle and skin contact, maximum probability will cause blood collection needles
Sliding broken finger, brings to blood donor compared with major injury.
Utility model content
For this purpose, the utility model embodiment provides a kind of finger tip blood-taking device, to solve in the prior art since finger tip is adopted
Conditioned reflex caused by the feeling of pain of blood makes blood donor's fast retractile arm, caused by the sliding broken skin skin of blood taking needle syringe needle, to confession
The technical issues of blood person damages.
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 finger tip blood-taking device, including locating piece are provided
And blood taking needle, the blood taking needle are detachably connected the locating piece；Run through on the locating piece and offers blood sampling hole, the positioning
It is provided with grip finger part on the bottom surface in the vertical blood sampling hole of block, the grip finger part is used for the finger tip blood-taking device
It is fixed on finger；The blood taking needle includes Power Component, connection handle and punctures syringe needle, and the Power Component is for providing driving
Power, one end of the connection handle are connected to the output end of the Power Component, and are slidably mounted in the blood sampling hole, the thorn
Broken syringe needle is detachably connected the one end of the connection handle far from the Power Component.When carrying out finger tip blood sampling, pass through the finger
The locating piece is fixed on finger finger tip by clamping element, at this point, the syringe needle distance that punctures refers to that at regular intervals, starting institute is stayed in face
Power Component is stated, drives the connection handle that the lancet head is driven slowly to be displaced to finger face, so that the syringe needle that punctures connects
It touches and punctures finger face.On the one hand, finger face is slowly punctured due to puncturing syringe needle, gives blood donor's certain reaction time, reduce pain
Pain；On the other hand, described when puncturing syringe needle and puncturing finger face, during blood donor retracts arm because of conditioned reflex, drive institute
