[0021] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0022] like Figure 1-4As shown, a culture tube for lymphocyte culture medium includes a tube body 1 provided with a cover body 11, and also includes an arc-shaped anti-slide plate 2 circumferentially arranged on the outer side of the tube body 1, and a sliding sleeve 21 is hingedly provided on the inner side of the anti-slide plate 2 to slide on the side wall of the tube body 1, and a pressure plate 22 is fixedly installed at one end of the anti-slide plate 2;

[0023] A convex ring 23 is fixed on the side wall of the tube body 1 . The tube body 1 slides relative to the anti-slide plate 2 , causing the convex ring 23 to push the anti-slide plate 2 in a lever motion and causing the pressure plate 22 to press against the cover body 11 .

[0024] Specifically, a strip-shaped anti-slip groove is provided on the cover body 11. When the tube body 1 is opened upward, multiple anti-slip plates 2 slide down to a predetermined position away from the end of the tube body 1 under the action of gravity, and the sliding sleeve 21 is limited by the raised ring 23 on the side wall of the tube body 1. At the same time, the ends of the anti-slip plates 2 where the pressure plate 22 is not provided are in a state of being close to each other.

[0025] Furthermore, a rubber pad is fixedly installed on the outer wall of the arc-shaped anti-slip plate 2 (i.e., the inner side of the arc-shaped recess) so that the tube body 1 has an anti-slip function after insertion. The bottom of the centrifuge's socket is expanded outward so that the end of the arc-shaped anti-slip plate 2 can be embedded therein, thereby increasing the placement stability of the tube body 1.

[0026] By inserting the tube body 1 with the anti-skid plate 2 into the socket of the centrifuge, and making the outer side of the anti-skid plate 2 fit against the inner wall of the socket, the rubber pad has a good anti-skid effect, and continuing to press the tube body 1 downward to make the convex ring 23 contact the end of the anti-skid plate 2, so that the end of the anti-skid plate 2 expands outward and is embedded in the socket, thereby increasing the centrifugal stability effect of the tube body 1. At the same time, with the anti-skid plate 2 using the sliding sleeve 21 as the support point, the pressure plate 22 at the other end of the anti-skid plate 2 is close to the cover body 11, and the circumferentially arranged pressure plates 22 radially clamp the cover body 11, thereby preventing the cover body 11 from loosening, effectively reducing the situation of poor sealing of the cover body 11, and solving the problem of blood stains being thrown out under the action of centrifugation.

[0027] As an embodiment further provided by the present invention, equidistantly arranged ridges 221 are fixedly mounted on the inner side of the pressing plate 22 , and the ridges 221 are engaged with the cover body 11 .

[0028] When the cover 11 is clamped by the pressing plate 22 , the convex strips 221 engage with the anti-slip grooves on the cover 11 to enhance the clamping effect of the cover 11 and prevent the cover 11 from rotating loose under centrifugal action.

[0029] As another embodiment further provided by the present invention, a collecting cover 3 is fixedly installed at the intersection of the pressing plate 22 and the anti-slip plate 2 , and a cover opening 31 that fits the side wall of the tube body 1 is provided on the collecting cover 3 .

[0030] Specifically, the collection cover 3 is located at the end of the cover body 11 , and the cover opening 31 faces the end of the cover body 11 .

[0031] Furthermore, a rubber membrane is fixedly installed between every two collecting covers 3 to connect the collecting covers 3 and also play a role of fitting and sealing. The collecting covers 3 are made of hard plastic covers as a whole.

[0032] After the anti-slide plate 2 is squeezed and deflected by the convex ring 23, the bottom of the cover opening 31 is pressed against the side wall of the tube body 1, and the rubber membrane is used to achieve sealing, which effectively reduces the situation where blood stains leak from the port of the cover body 11 and are thrown out at will. If blood stains leak, the blood stains will enter the collection cover 3 along the cover opening 31 and be collected, and recovered in a centralized manner at a later time, effectively reducing the problem of blood stain contamination.

[0033] As another embodiment further provided by the present invention, the collecting hood 3 is further provided with an inner opening 32 connected to the hood opening 31 .

[0034] Specifically, the inner opening 32 is spirally bent toward the inside of the collecting cover 3 .

[0035] The blood stains entering the collection cover 3 gradually flow into the inner opening 32 and are stored in cooperation with the spiral of the inner opening 32 for later flushing, thereby increasing the collection amount of the cover opening 31 and reducing the accumulation of blood stains at the cover opening 31 and affecting the sealing of the cover body 11.

[0036] As another embodiment further provided by the present invention, a notch is formed on the inner opening 32 , and an elastic membrane 33 is fixedly installed in the notch.

[0037] Specifically, the notch of the inner opening 32 faces the end of the cover body 11 , and the elastic membrane 33 is a rubber membrane.

[0038] The blood stains that enter the inner opening 32 cause the elastic membrane 33 to deform under the action of centrifugal force and gradually come into contact with the port of the cover body 11, thereby sealing the gap at the port of the cover body 11 and solving the problem of the cover body 11 being loose and leaking. In addition, the elastic membrane 33 will also increase the force deformation effect due to the adhesion of the blood stains, so that the elastic membrane 33 can perform the sealing work.

[0039] Working principle: by inserting the tube body 1 with the anti-skid plate 2 into the socket of the centrifuge, and making the outer side of the anti-skid plate 2 fit against the inner wall of the socket, so that it has a good anti-skid effect under the action of the rubber pad, and continuing to press down the tube body 1, so that the convex ring 23 contacts the end of the anti-skid plate 2, so that the end of the anti-skid plate 2 expands outward and embeds into the socket, thereby increasing the centrifugal stability effect of the tube body 1, and at the same time, with the anti-skid plate 2 using the sliding sleeve 21 as the support point, the pressure plate 22 at the other end of the anti-skid plate 2 is close to the cover body 11, so that the circumferentially arranged pressure plates 22 radially clamp the cover body 11 to prevent the cover body 11 from loosening.

[0040] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
