Detailed implementation manner

[0018] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present utility model, and should not be construed as a limitation to the present utility model.

[0019] As Figures 1 to 3 shown, wherein Figure 1 is the overall structural schematic diagram of the component scale - marked test tube for separating mesenchymal stem cells, Figure 2 is the cross - sectional view of the screw cap 104, Figure 3 is the structural schematic diagram of the plug 109. The present utility model provides a component scale - marked test tube for separating mesenchymal stem cells: including a test tube body 100 and an auxiliary component. The bottom of the test tube body 100 has a support part 101, and the side is provided with an identification area 102 and scale lines 103. The auxiliary component includes a screw cap 104, a first gasket 105, a second gasket 106 and a ventilation component. The ventilation component includes a sterile filter membrane 108 and a plug 109. Through the foregoing solution, it can be realized that while rapid marking is achieved during use, it can be placed and used without matching a test tube rack, which is beneficial to reducing the use cost. It can be understood that the foregoing solution can enable the test tube body 100 to be placed and used without matching a test tube rack, which is beneficial to reducing the use cost.

[0020] In this embodiment, the bottom of the test tube body 100 has a support part 101, and the side is provided with an identification area 102 and scale lines 103. The test tube body 100 is made of a polymer material such as polypropylene (PP) or polystyrene (PS) or borosilicate material. The inner and outer surfaces are smooth, with high transparency, and the test tube body 100 adopts a seamless design, that is, the tube body is made by a one - time molding process during production without seams or gaps, thereby reducing the possibility of microbial intrusion. The bottom of the test tube body 100 has the support part 101, and the support part 101 is made of the same material as the test tube body 100 and is integrally formed. The identification area 102 is printed with environmentally friendly ink and can remain clear for a long time, and is used to paste or directly print information such as date, number, source, use, etc., improving the convenience and traceability of storage management and facilitating rapid marking. The scale lines 103 are convenient for observing the liquid level inside. When the scale lines 103 are set, they are set upward from the support part 101. Since the support part 101 is in a transparent state, the liquid situation in the semi - circular cavity at the bottom of the test tube body 100 can be directly observed.

[0021] Among them, the threaded cap 104 is detachably connected to the test tube body 100 and is located at the top of the test tube body 100. The first gasket 105 is detachably connected to the test tube body 100 and is located on one side of the test tube body 100 close to the threaded cap 104. The second gasket 106 is detachably connected to the test tube body 100 and is located between the test tube body 100 and the threaded cap 104. The ventilation member is arranged on one side of the test tube body 100. A stepped threaded cavity is arranged at the top of the test tube body 100. The first gasket 105 can be directly placed into the stepped threaded cavity and is limited by abutting through installing the threaded cap 104. The cross-section of the threaded cap 104 is T-shaped. An installation groove is arranged on the end face at the top of the test tube body 100 to facilitate the direct installation of the second gasket 106. When the ventilation member needs to maintain the pressure balance in the tube, it can allow the gas to flow freely while preventing the passage of microorganisms.

[0022] Secondly, the threaded cap 104 is provided with anti-slip protrusions 107, and the anti-slip protrusions 107 are annularly arranged on the threaded cap 104. The function of the anti-slip protrusions 107 is to facilitate the screwing off or screwing tight installation of the threaded cap 104.

[0023] Then, the sterile filter membrane 108 is arranged in the ventilation hole of the test tube body 100; the plug 109 is threadedly connected to the test tube body 100 and is located on one side of the test tube body 100 close to the sterile filter membrane 108. A stepped ventilation threaded hole is arranged on one side of the test tube body 100. The sterile filter membrane 108 is arranged in the ventilation port to ensure gas exchange and prevent the passage of microorganisms. The cross-section of the plug 109 is Chinese character 'zhong'-shaped, and the outer threaded end can be directly installed in the ventilation threaded hole of the test tube body 100, and the sterile filter membrane 108 will not be abutted and broken after installation. An O-shaped gasket is arranged at the contact surface between the plug 109 and the test tube body 100 for sealing during installation.

[0024] Furthermore, a weight reduction cavity 110 is arranged on the support portion 101, and the weight reduction cavity 110 penetrates through the support portion 101 and is annularly arranged on the support portion 101. The weight reduction cavity 110 facilitates the overall weight reduction of the test tube body 100.

[0025] Finally, the number of the weight reduction cavities 110 is four. The purpose of setting four weight reduction cavities 110 is to further not affect the overall strength of the test tube without affecting the weight reduction.

[0026] When using the present utility model to achieve rapid marking during use, it can be placed and used without matching a test tube rack, which helps reduce the use cost. During use, the threaded cap 104 is unscrewed by cooperating with the anti-slip protrusion 107. At this time, liquid can be put into the test tube body 100. The scale line 103 can be used for observing the liquid level. After the liquid is put in, the threaded cap 104 is screwed on to seal the top opening of the test tube body 100. The first sealing gasket 105 and the second sealing gasket 106 improve the sealing performance. The support portion 101 facilitates the direct placement of the test tube body 100 without the need to equip a test tube rack. The identification area 102 is printed with environmentally friendly ink and can remain clear for a long time, and is used to paste or directly print information such as date, number, source, and use, improving the convenience and traceability of storage management and facilitating rapid marking. The weight reduction cavity 110 can achieve the overall lightweight design of the test tube. When it is necessary to maintain the pressure balance inside the tube, the plug 109 can be unscrewed. At this time, gas can freely flow through the sterile filter membrane 108 while preventing the passage of microorganisms, for internal and external air exchange. Furthermore, when achieving rapid marking during use, it can be placed and used without matching a test tube rack, which helps reduce the use cost.

[0027] The above-disclosed are only one or more preferred embodiments of the present application, and the scope of rights of the present application cannot be limited thereby. Those of ordinary skill in the art can understand all or part of the processes of implementing the above embodiments, and the equivalent changes made according to the claims of the present application still fall within the scope covered by the present application.
