The fixing piece is divided into a first hinge piece, a second hinge piece and a buckling piece 6 according to functional properties, the first hinge piece and the second hinge piece are both arranged at the first side edge of the first shell 3 and the second shell 2 in the axial direction, and the distance between the first hinge piece and the second hinge piece is greater than the axial length of 1/3 shells, so that the first shell 3 and the second shell 2 can be folded through the corresponding side edges, and the condition that the shells are lost when the blood collecting barrel 1 is stored daily can be effectively improved; buckling piece 6 swing joint is in first casing 3 axial ascending second side middle part, and is equipped with the buckling groove 17 that matches with buckling piece 6 on the second casing 2, so not only can be so that the convenient opening of blood sampling section of thick bamboo 1, can also promote the stability of first casing 3, second casing 2 when the lock.

The fixed setting of insulated column 18 is in the inboard middle part of first casing 3, and insulated column 18 can just in time cut off syringe needle emission chamber 24 and blood collection vessel cavity 25 completely, and such design is in order to with syringe needle emission chamber 24 and the strict differentiation of blood collection vessel cavity 25, avoids when the syringe needle finishes pricking the finger back doctor upset blood sampling section of thick bamboo 1 upper and lower direction and carries out the blood collection operation, and the blood that probably exists drips on blood taking needle 14 and causes the pollution on tip blood sampling tube 20.

The needle mounting seat 15 is provided with a mounting groove 13 matched with the blood taking needle 14; the two clamping grooves 9 are symmetrically distributed on two sides of the first shell 3, so that the clamping piece 11 can effectively stop the needle mounting seat 15 when the needle mounting seat 15 compresses the launching spring 16 to a set position; the left side of the buckling groove 9 is provided with a matched annular tightening boss 7, and the right side of the buckling groove 9 is provided with a matched fixed table 12; the triggering device further comprises a shifting ring 8, a low-elasticity belt 10 and a buckling piece 11, the shifting ring 8, the buckling piece 11 and the fixing platform 12 are connected through the low-elasticity belt 10, and the low-elasticity belt 10 can effectively ensure that the buckling piece 11 does not move radially relative to the circle center of the blood sampling tube 1 when the triggering device is fixed.

One end of the pressing plate 22 is fixed right above the second shell 2 at the position of the blood collecting cavity 25, a reset spring 23 is arranged between the middle of the pressing plate 22 and the second shell 2 to support the pressing plate 22, and a cylinder at the lower part of the other end of the pressing plate 22 penetrates into the blood collecting cavity 25 through a pressing hole groove 21 matched with the second shell 2, so that the design has two advantages, firstly, the reset spring 23 effectively ensures that the pressing plate 22 cannot generate mistaken actions to extrude the rubber head 19 and then suck air to pollute the peripheral blood collecting tube 20, secondly, compared with a mode of directly holding the rubber head 19 by hand, a mode that the cylinder under the pressing plate 22 penetrates through the pressing hole groove 21 to extrude the rubber head 19 on the auxiliary platform 5 by pressing the pressing plate 22 has easy operability and good stability. The auxiliary table 5 is arranged in the middle of the inner side of the first shell 3, and the auxiliary table 5 and the pressing hole groove 21 are positioned on the same vertical line; the quantity of stationary dog 4 is two, and two stationary dogs 4 evenly set up the rear side at auxiliary table 5 along first casing 3 axial, adopts two stationary dogs 4 not only can have good stability when making tip heparin tube 20 installed, but also can practice thrift certain material cost.

The three-edged lancet 14 is used as the lancet 14 because the three-edged lancet 14 has a good pricking effect and a small pain.

The first shell 3 and the second shell 2 are both made of hard plastics or resin; the housing at needle firing chamber 24 is opaque; the design is to hide the needle when the blood taking needle 14 pricks the finger, so that the fear of children can be effectively reduced when the children cannot see the blood taking needle 14; the shell at the blood collection cavity 25 is transparent, so that the doctor can conveniently align the nozzle of the peripheral blood collection tube 20 with the bleeding point to collect blood in the blood collection process.

When in use, firstly, the process of assembling the blood sampling device is as follows: a doctor turns the second shell 2 open by opening the fastener 6, pushes the needle mounting seat 15 to the right side surface of the isolation column 18 and plugs the fastener 11 into the fastener groove 9, simultaneously buckles the poking ring 8 on the annular tightening boss 7, then installs the blood taking needle 14 on the needle mounting seat 15 through the mounting groove 13, installs the straw part of the peripheral blood taking tube 20 on the fixing claw 4, simultaneously puts the rubber head 19 of the peripheral blood taking tube 20 on the auxiliary table 5, and finally turns and covers the second shell 2 on the first shell 3 and fixes the first shell 3 and the second shell 2 through fastening; secondly, the process of sampling blood from fingertips. Firstly, a doctor holds the middle part of the blood collecting tube 1 by one hand in a pen holding posture, and the cavity opening of the needle head launching cavity 24 faces downwards; then the mouth of the needle launching cavity 24 is aligned with the fingertip, the poking ring 8 is poked by the index finger or the middle finger, and at the moment, the launching spring 16 pushes the needle mounting seat 15 to advance due to the elasticity formed by compression and the blood taking needle 14 rapidly punctures the finger; then, a doctor only needs to rotate the blood collecting cylinder 1 in a pen-rotating mode to enable the cavity opening of the blood collecting cavity 25 to face downwards, the pipe opening of the peripheral blood collecting tube is aligned to a bleeding point through the characteristic that the shell material at the position of the blood collecting cavity 25 is transparent, and then the rubber head 19 is squeezed by pressing the pressing buckle plate 22 to suck blood samples of fingertips; finally, the slide is taken out, and the blood sample in the peripheral blood collection tube 20 is dripped on the slide by pressing the pressing plate 22 again.

The above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
