Description

Sampling test tube

Technical Field

The utility model relates to the technical field of sampling equipment, in particular to a sampling test tube.

Background

As shown in fig. 1 (the drawing of the chinese patent application No. 202220081562.3), the central blood station blood collection tube disclosed therein comprises: the guide pipe 1, the annular plate 2, the piston 4, the groove 5, the guide groove 6 and the like, wherein the piston 4 is made of rubber material and can play a role in sealing. When in use, the injector needle pierces the piston 4 along the guide groove 6 and then enters the catheter 1, and the injector needle is withdrawn after the injector needle is used, so that the sealing purpose can be achieved.

After the drunk driving suspects are brought to a hospital, two blood samples are generally taken, the volume of each blood sample is 2ml to 5ml, and each blood sample is filled into a material evidence bag for sealing and storage. The typical material evidence bag can be as disclosed in China patent with the application number of CN201220489336.5, and discloses a bearing anti-counterfeiting bag made of sheet materials, which comprises a bag body, wherein an anti-counterfeiting bag opening is formed in the upper end of the bag body, an anti-counterfeiting security strip is adhered to the upper extension outside of the lower front wall of the bag body, and if the anti-counterfeiting strip is illegally torn, a STOP character is reserved at the bag opening, so that the safety performance is stronger; when tearing the defending security bar, the anti-fake typeface that can't wipe will appear in the bonding department, and the hot melt adhesive is disposable, once destroy, the unable restoration of sack, not only can prevent like this that article in the sack from dropping, can also avoid the sack to be opened maliciously in transportation and transmission. Namely, the upper end of the bag is provided with an opening, the opening is attached and sealed after the blood collection tube is filled, and the bag can be damaged when the blood collection tube is taken out, so that the aim of sealing and storing is fulfilled.

However, since the anticoagulated liquid blood sample is stored in the blood collection tube, if the anticoagulated liquid blood sample enters the bag from two top corners at the opening of the bag through the syringe needle and then enters the blood collection tube from the piston 4 shown in fig. 1, the blood sample in the anticoagulated liquid blood sample can be replaced by other blood samples or diluted with water through the syringe. Or the like after piercing the bag with a tiny syringe needle in an unobtrusive location, these tiny piercing holes are generally difficult to find by personnel of the authentication mechanism because of the heavy daily effort, and some have been used to achieve this, and thus, it is desirable to prevent such events.
