Referring to fig. 1-4, a vein puncturing device comprises a base 1, a vertical plate 16 is disposed at the rear side of the base 1, a sliding groove 8 is disposed on the vertical plate 16, and an auxiliary device 9 is slidably connected to the vertical plate 16.

Wherein, the bottom of base 1 is equipped with the silica gel slipmat.

Through being equipped with the silica gel slipmat, effectively increase the frictional force of device and desktop, and then improve the stability of device.

Wherein, the rear end of auxiliary device 9 is equipped with the third slider, and the third slider sets up in spout 8.

Be equipped with the circular slot on auxiliary device 9, the top of circular slot is equipped with fixing base 7, and the bottom of circular slot is equipped with angle scale 6, rotates through the bearing on the fixing base 7 and connects axis of rotation 5, and one side of axis of rotation 5 is equipped with injection device 4.

The other side of axis of rotation 5 runs through fixing base 7 and with pointer 10 fixed connection, axis of rotation 5 and circular slot rotate to be connected.

During the use, can hand injection unit 4, because injection unit 4 all rotates through axis of rotation 5 and fixing base 7, circular slot and is connected, and pointer 10 also corresponding rotation when axis of rotation 5 rotates.

Therefore, the nurse can change the needle holding angle by rotating the injection device 4, and can dynamically grasp the needle holding angle of the nurse by the engagement between the angle scale 6 and the pointer 10, thereby achieving the training purpose.

Wherein, injection device 4 includes tight loop 18, and tight loop 18 and axis of rotation 5 fixed connection are equipped with syringe needle 19 in the tight loop 18, and the outer wall longitudinal symmetry cover of syringe needle 19 is equipped with second retainer plate 20, and second retainer plate 20 of downside passes through third spring 2 with tight loop 18 and is connected.

When the auxiliary device is used, the injection needle 19 is arranged in the fastening ring 18, the fastening ring 18 is connected with the second fixing ring 20 on the injection needle 19 through the third spring 2, at the moment, the third spring 2 gives a force to the second fixing ring 20 to be close to the fastening ring 18, so that after a nurse determines a needle holding angle, the auxiliary device 9 can be controlled to slide to the upper side of the transverse plate 17 along the sliding groove 8, and then the third spring 2 is stretched, so that the injection needle 19 moves downwards in the fastening ring 18, and a puncture action is realized.

The second fixing ring 20 is provided on the injection needle 19, so that the injection needle 19 can be prevented from coming off the fastening ring 18.

Base 1's top is equipped with diaphragm 17, be equipped with a plurality of pinhole 3 on diaphragm 17, pinhole 3's inner wall is equipped with slider 11, slider 11's right-hand member is equipped with cavity 14, slider 11 is the little big olive in the middle of the both ends, slider 11's right-hand member is equipped with corresponding cavity 14, slider 11's right-hand member and cavity 14 are connected through first spring 15, the front side of cavity 14 is equipped with the second spout, be equipped with draw runner 12 in the second spout, the last lower extreme and the second spout of draw runner 12 pass through second spring 13 and are connected, the outer end of draw runner 12 extends to diaphragm 17's front side, the inner of draw runner 12 is tangent with slider 11.

Wherein, the aperture of the pinhole 3 is reduced from left to right.

In use, since the slider 11 is connected to the cavity 14 via the first spring 15, when the slider 11 is subjected to a force, the first spring 15 will be compressed, so that the slider 11 moves into the cavity 14.

Because slider 11 is the big olive shape in the middle of the little two, consequently along with slider 11's motion, will extrude draw second spring 13 of draw runner 12 and to the motion of outer end, through observing the outer end protrusion length of runner 12 under the different dynamics, can help the nurse to understand the size of its puncture dynamics directly perceivedly, be of value to the training of venipuncture.
