Detailed Description
In order to make the technical solution of the present invention better understood, the technical solution of the present invention will be further described with reference to the accompanying drawings.
Referring to fig. 1 to 5, the present invention relates to a biological sample collection tube, including an outer tube 1 with an opening at the upper end and the lower end, the outer tube 1 is a transparent medical PC plastic tube, the upper end of the outer tube 1 is connected with an upper connection block 2, the upper connection block 2 is made of cylindrical plastic, the upper connection block 2 is provided with a central hole, a sliding rod 3 is slidably connected in the central hole, the upper end of the sliding rod 3 is connected with a pressure head 31, the top of the pressure head 31 is provided with anti-slip patterns, the lower end of the sliding rod 3 extends into the outer tube 1 and is connected with a swab 4, the swab 4 includes a rod portion and a cotton ball at the lower end, and the water absorption of the cotton ball is used to absorb biological samples such as blood, urine, etc.
A return spring 32 sleeved on the sliding rod 3 is arranged between the pressure head 31 and the upper connecting block 2, and the return spring 32 is used for the swab at the lower end of the sliding rod 3 to return. When gathering biological sample, operating personnel overcomes reset spring 32's elasticity and presses down pressure head 31 for the cotton ball of swab 4 lower extreme stretches out outer tube 1 and gathers biological sample, loosens pressure head 31 after gathering, and the swab 4 that has biological sample is inside protected by automatic retraction outer tube 1 under reset spring 32 elasticity, makes operating personnel can not touch the sample on the swab, and then can not polluted by the sample.
