The movable cover in the periphery of collector body 1 is equipped with the lantern ring 5 parallel with the boss, a plurality of logical grooves 6 have evenly been seted up on the surface of lantern ring 5, and this embodiment uses two logical grooves 6 to introduce as the example. The two through grooves 6 are arranged on two sides of the collector tube body 1, a threaded rod 7 penetrates through one through groove 6, a connecting rod 11 penetrates through the other through groove 6, the top of the threaded rod 7 is rotatably connected with a boss of the collector tube body 1, the bottom of the threaded rod 7 penetrates through the lantern ring 5 to be fixed with the grab handle 8, the threaded rod 7 is in threaded connection with the lantern ring 5, and the lantern ring 5 moves in the vertical direction relative to the collector tube body 1 by rotating the threaded rod 7; the top of connecting rod 11 with pass collector body 1 the boss be connected with connecting block 4, the bottom of connecting rod 11 passes lantern ring 5 and is connected with second support block 12, and the diameter that second supported block 12 is greater than the internal diameter that corresponds logical groove 6.

Further, in the above technical solution, an opening 14 is provided at a position of the collar 5 close to the surface of the scale mark 13, and the width of the opening 14 is greater than the width of the scale mark 13, so that a user can read a numerical value conveniently. The indicator 15 is arranged on the inner side of the opening 14, the indicator 15 is arranged at one end close to the scale mark 13 in an inclined way, and the structure design enables a user to more intuitively and clearly show the actual data at the position of the lantern ring 5 through the indicator 15 at the opening 14.

Further, in above-mentioned technical scheme, the surface veneer of grab handle 8 has the rubber pad, the surface of rubber pad is provided with anti-skidding line, when the user grips the surface of grab handle 8, through the rubber pad on grab handle 8 surface to can increase the frictional force between user's hand and the grab handle 8, and then convenient to use person can firmly grip grab handle 8.

Example 2

Embodiment 2 is different from embodiment 1 in that the number of the through grooves 6 formed in the lantern ring 5 is different, and the stop rod 9 is additionally arranged in the through grooves 6, so that the process of vertical movement of the lantern ring 5 can be further limited, the lantern ring 5 can stably move in the vertical direction, the movement track of the lantern ring 5 is prevented from deviating when moving, and the blood volume or the dosage of the blood to be extracted is caused to deviate.

As shown in fig. 2-4, in this embodiment, three through grooves 6 are uniformly formed in the collar 5, wherein a threaded rod 7 and a connecting rod 11 are respectively inserted into two through grooves 6, the top of the threaded rod 7 is rotatably connected with a boss of the collector tube body 1, the bottom of the threaded rod 7 penetrates through the collar 5 and is fixed with the handle 8, the threaded rod 7 is in threaded connection with the collar 5, and the collar 5 moves in the vertical direction relative to the collector tube body 1 by rotating the threaded rod 7; the top of connecting rod 11 with pass collector body 1 the boss be connected with connecting block 4, the bottom of connecting rod 11 passes lantern ring 5 and is connected with second support block 12, and the diameter that second supported block 12 is greater than the internal diameter that corresponds logical groove 6.

Wear to be equipped with gag lever post 9 in newly-increased logical groove 6, the top and the boss of collector body 1 of gag lever post 9 are connected, the bottom of gag lever post 9 is passed lantern ring 5 and is connected with first piece 10 of supporting, through setting up gag lever post 9, can be vertical motion's process to lantern ring 5 and play further limited action for lantern ring 5 can be steady move in vertical direction.

Further, in the above technical solution, the diameter of the first abutting block 10 is greater than the inner diameter of the corresponding through groove 6, and here, the first abutting block 10 and the second abutting block 12 are respectively and fixedly connected with the corresponding limiting rod 9 and the surface of the connecting rod 11, so that one end of the collar 5 can be prevented from being separated from the outer peripheral surface of the limiting rod 9, and the movement range of the piston pull rod 3 is limited to a certain extent, so that the blood collection amount is limited to a certain extent.

The specific operation mode is as follows:

before using, before the user need take a blood sample work, the actual numerical value of the volume of taking a blood sample as required, it drives threaded rod 7 and is circular motion to rotate grab handle 8 in step, utilize the internal thread that leads to 6 inner walls of lantern ring 5 and the external screw thread structure of threaded rod 7's mating reaction, make lantern ring 5 can only slide from top to bottom in collector body 1's outside, and utilize threaded rod 7's limiting displacement, make lantern ring 5 can be more firm in the motion of vertical direction, thereby it gets more steady to drive indictor 15 and move in vertical direction, when pointing to the position department of corresponding blood sampling numerical value until indictor 15, stop rotating grab handle 8.

During the use, the user pierces collector's artery department with perpendicular or 40  angle with collector syringe needle 2 of the good lantern ring 5 position of adjustment, and pulling piston pull rod 3, make piston pull rod 3 be vertical motion, because collector body 1 is inside to take place atmospheric pressure and change, make the blood of artery get into collector body 1 in, when first piece 10 and the surperficial conflict of lantern ring 5 of supporting, piston pull rod 3 stop motion, thereby play the ration effect to the blood that gets into collector body 1 inside, this embodiment has specifically solved among the prior art when gathering arterial blood sample, can not be effective, the problem of accurate control blood volume.

The technical scheme can realize quantitative blood sampling and quantitative drug delivery. When the process of realizing the ration and dosing, arrange collector syringe needle 2 in the medicament earlier, the rotary grab handle 8 makes threaded rod 7 be circular motion, under threaded rod 7 and the screw-thread fit effect who leads to groove 6, make the lantern ring 5 move in vertical direction, lantern ring 5 drives index mark 15 and is vertical motion simultaneously, make the index mark 15 to the scale position that needs the extraction dose, then through pulling piston pull rod 3, make the medicament get into collector body 1 in, when the second supports piece 12 and lantern ring 5 inconsistent, plug pull rod 3 stop motion, in pricking collector syringe needle 2 the blood vessel afterwards, promote piston pull rod 3, all inject into the medicament in the collector body 1.

While certain exemplary embodiments of the present invention have been described above by way of illustration only, it will be apparent to those of ordinary skill in the art that the described embodiments may be modified in various different ways without departing from the spirit and scope of the present invention. Accordingly, the drawings and description are illustrative in nature and should not be construed as limiting the scope of the invention.
