Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides a multi-functional blood liquid tube sampler, including cylinder 1, syringe needle 2, piston 7 and pull rod 4, be fixed with centre of a circle department and have limiting plate 12 of through-hole 13 on the inner wall of cylinder 1, limiting plate 12 can set up in different positions as required, limiting plate 12's last wall shaping has spacing round pin 10, piston 7's lower wall has the spacing groove 11 with spacing round pin 10 looks adaptation, spacing

round pin

10 and 11 block in the spacing groove, can carry on spacingly to piston 7, avoid piston 7 to take place to rotate, piston 7's lower wall is fixed with fixed block 9, through-hole 13 and fixed block 9 looks screw closure are run through on the top of pull rod 4, pull rod 4 and through-hole 13 clearance fit, after pull rod 4 and fixed block 9 screw closure, under the effect of pull rod 4 and fixed block 9, can drive piston 7 and take place to remove.

Specifically, as shown in fig. 1 and 3, the outside shaping in bottom of pull rod 4 has flange 6, the inner chamber of flange 6 is equipped with sealed cap 5, sealed cap 5 closes soon through the screw thread with the inner wall of the inner chamber of flange 6 and is connected, the top shaping of cylinder 1 has sealed cap 5's connecting block 3 that closes soon mutually, under the blood sampling state, syringe needle 2 is connected with connecting block 3, sealed cap 5 closes soon at the inner chamber of flange 6, be convenient for staff's blood sampling operation, storage state is down, sealed cap 5 closes soon in the outside of connecting block 3, sealed cap 5 can seal cylinder 1, and pollution is reduced.
