Abstract

The invention provides a disposable saliva collector with a protection device and convenient for puncture. The disposable saliva collector comprises a self-locking tube cap, a self-locking tube body,a saliva collection cup and a cryopreservation tube; a first ratchet wheel is arranged on the top circumference of the inner wall of the self-locking tube cap; a first connecting part is arranged on the inner side circumference of the self-locking tube cap; a second connecting part matched with the first connecting part is arranged at the upper end of the outer wall of the self-locking tube cap; asecond ratchet wheel matched with the first ratchet wheel is arranged below the second connecting part; a third connecting part is arranged at the lower end of the outer wall of the self-locking tubebody; a diaphragm is arranged on the bottom surface of the inner wall of the self-locking tube body; the saliva collection cup sequentially comprises a collecting cup and a connecting pipe from top to bottom; the connecting pipe comprises a first connecting pipe body and a second connecting pipe body; a fourth connecting part and a piercing mechanism are arranged on the inner side wall of the first connecting pipe body; a fifth connecting part is arranged on the inner wall of the second tube body; and a sixth connecting part is arranged at the top end of the outer wall of the cryopreservationtube. The disposable saliva collector provided with the protection device and convenient for puncture is convenient to operate and safe to use, and the tube cap cannot be unscrewed.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to a disposable saliva collector with a protective device and convenient for puncturing. Background technique [0002] Saliva sample collection is a method of obtaining DNA / RNA that is harmless and painless to the human body. The product collects the oral secretion saliva sample through the saliva collection cup, and evenly mixes the collected saliva with the saliva preservation solution to ensure the integrity of the DNA / RNA in the saliva sample. [0003] The original technology is to collect oral saliva samples through the saliva collection cup first, then unscrew the tube cover of the saliva preservation solution, and pour the saliva preservation solution into the saliva collection cup to mix with saliva. This method is complicated to operate. There may be a risk of saliva-preserved fluid coming into contact with the human body or the outside world. Contents of the invention [0...
