[0034] Referring to Figures 1 to 8 The present utility model provides a digestion and lysis reaction device 100.
[0035] In an embodiment of the present utility model, the digestion and lysis reaction device 100 is used to perform digestion and lysis reactions on reactants with a relatively low density. It can be understood that the reactants can be animal hairs, feathers, or plastic products, etc. The digestion and lysis reaction device 100 includes a reaction tube 10, which is integrally formed of a medical-grade transparent plastic material or made of glass. The reaction tube 10 is conical and forms a reaction cavity 10a with one end open.
[0036] The sealing end cap 20 can also be made of a plastic material or glass. The sealing end cap 20 is convexly provided with a sealing flange (not shown in the figure). The sealing flange is clamped to the open end of the reaction cavity 10a to connect the sealing end cap 20 to the reaction tube 10. The sealing end cap 20 seals the reaction cavity 10a to provide a sealed reaction environment and prevent external impurities from interfering with the detection reaction.
[0037] A pressing member 30, the pressing member 30 includes a connecting rod 31, a pressing portion 32 and an avoiding portion 33 connected to each other. The connecting rod 31 is detachably connected to the sealing end cap 20. The pressing portion 32 and the avoiding portion 33 are accommodated in the reaction cavity 10a. The pressing portion 32 is used to press the reactant in the reaction cavity 10a, and the avoiding portion 33 is used to avoid the reaction solution.
[0038] The technical solution of the present utility model adopts a reaction tube 10, which forms a reaction cavity 10a. One end of the reaction cavity 10a is open and is used to accommodate a reaction solution. A sealing end cap 20 is detachably covered on the open end of the reaction cavity 10a. The connecting rod 31 of the pressing member 30 is detachably connected to the sealing end cap 20, and the pressing portion 32 and the avoiding portion 33 are accommodated in the reaction cavity 10a. In this application, the reactants are accommodated in the reaction cavity 10a, and the reactants are pressed into the reaction cavity 10a by the pressing portion 32 connected to the connecting rod 31 so that they are completely immersed in the reaction solution. The avoiding portion 33 avoids the reaction solution, so that the reaction solution completely immerses the reactants, thus avoiding the situation that reactants with a smaller density float on the surface of the reaction solution and cannot react completely, and further improving the accuracy of the detection result.
[0039] Please refer to Figures 1 to 4 In an embodiment of the present utility model, the pressing portion 32 includes a pressing plate 321. The pressing plate 321 is connected to the end of the connecting rod 31 by an integral molding method. The surface of the pressing plate 321 is provided with first liquid passing holes 321a penetrating through its upper and lower surfaces. The plurality of first liquid passing holes 321a are used to avoid the solution in the reaction cavity 10a, that is, the plurality of first liquid passing holes 321a form the avoiding portion 33. The aperture of the first liquid passing hole 321a should be as small as possible so that after the pressing plate 321 presses the reactants into the reaction solution, the reaction solution can flow to the upper plate surface of the pressing plate 321 through the first liquid passing holes 321a, avoiding the situation that the internal pressure is too large and bursting the reaction tube 10.
[0040] Furthermore, the pressing portion 32 further includes a sealing ring 322. A clamping groove 321b is formed on the outer side surface of the pressing plate 321. The cross-section of the clamping groove 321b is semi-circular. The sealing ring 322 is made of an elastic material, such as silicone, rubber, etc. In this application, the sealing ring 322 is preferably self-lubricating silicone. The sealing ring 322 is clamped in the clamping groove 321b and elastically abuts against the cavity side wall of the reaction cavity 10a. In this way, it can be avoided that during the process of the pressing plate 321 pressing down, the reactants flow upward through the gap between the pressing plate 321 and the cavity side wall of the reaction cavity 10a, thereby improving the stability of the use of the digestion and lysis reaction device 100.
[0041] Please refer to Figure 7 and Figure 8, of course, for some reactants with large shapes and small densities, such as feathers, etc., the gap between the two can also be used for avoidance. In another embodiment of the present application, the pressing plate 321 and the cavity side wall of the reaction cavity 10a form an avoidance gap 33a. The avoidance portion 33 is the avoidance gap 33a. The width of the avoidance gap 33a allows the reaction solution to flow upward, and the reactant is pressed in the middle of the reaction solution. In this way, the structure of the pressing member 30 is relatively simple and easy to produce and manufacture.
[0042] Please refer to again Figure 5 and Figure 6 , in yet another embodiment of the present application, the pressing portion 32 includes a reaction receiving box 323. The reaction receiving box 323 is connected to the end of the connecting rod 31 and forms a receiving space 323a. The avoidance portion 33 includes a plurality of second liquid passing holes 33b that communicate the receiving space 323a and the reaction cavity 10a. The receiving space 323a is used to receive the reactant. The reaction receiving box 323 extends into the reaction cavity 10a, and the reaction solution enters the receiving space 323a through the second liquid passing holes 33b to digest and lyse the reactant therein.
[0043] Specifically, the reaction receiving box 323 includes a box body 3231 and a box cover 3232. The box cover 3232 is connected to the end of the connecting rod 31 by an integral molding method. The box body 3231 is detachably connected to the box cover 3232. Specifically, the box cover 3232 and the box body 3231 are threadedly connected. In this way, the connection between the two is not only stable but also convenient for disassembly and assembly, facilitating the tester to put the reactant into the receiving space 323a and then place it into the reaction cavity 10a conveniently. After the reaction, it is also convenient to collect the residue after the reaction. It can be understood that the box body 3231 and the box cover 3232 can also be connected by a buckle, and no specific limitation is made here.
[0044] In an embodiment of the present application, a plugging hole 20a is opened in the middle of the sealing end cover 20. The end of the connecting rod 31 away from the pressing portion 32 is plugged into the plugging hole 20a. In this way, the installation and structure of the connecting rod 31 are relatively simple.
[0045] The above are only the preferred embodiments of the present utility model, and do not limit the patent scope of the present utility model. Any equivalent structural transformation made under the inventive concept of the present utility model by using the content of the specification and drawings of the present utility model, or directly / indirectly applied to other related technical fields, is included in the patent protection scope of the present utility model.
