[0019] The preferred embodiments of the present utility model are given below in conjunction with the accompanying drawings and described in detail.

[0020] like Figure 1 As shown, a sterilization chemical indicator device according to a preferred embodiment of the utility model comprises two relatively connected tubes 1 and a card 4 arranged in the tubes 1, wherein the card 4 is confined in the space within the two tubes 1 and remains basically motionless, so that the surrounding space of the card 4 remains relatively unchanged, the indicator on the card 4 is relatively fixed in a stable and unchanging space, and the contacting sterilization medium is also relatively stable, thereby ensuring the stability of the color change of the sterilization mark of the sterilization indicator and ensuring the accuracy of the test result.

[0021] Combination Figure 2-Figure 3 The tube 1 is a test tube-shaped PC material capsule-shaped transparent tube structure, and the PC material with good temperature resistance and transparency is selected, and the test tube-shaped tube 1 is produced by injection molding. In this embodiment, the inner diameter of the tube 1 is 6.0mm-6.5mm, and the depth of the tube 1 is 25mm-26mm.

[0022] The tube 1 is provided with two convex points 21, 22 and two concave points 23, 24 at the tube mouth 2, and the tube mouths 2 of the two tubes 1 are relatively buckled to form a capsule shape. The convex points 21, 22 of one tube 1 and the concave points 23, 24 of the other tube 1 are relatively matched. In this embodiment, the convex points 21, 22 are pointed (inverted V-shaped) convex points extending from the tube body axially toward the other tube 1, and the concave points 23, 24 are V-shaped concave points that are recessed from the tube mouth 2 toward the tube body axially. After the tube mouths 2 of the two tubes 1 are relatively buckled, the pointed convex points coincide with the V-shaped concave points. When connecting, only a small amount of adhesive is needed to be applied to the pointed convex points to bond and form a capsule-shaped device. In this way, the concave-convex design can facilitate the two tube mouths 2 to be neatly docked without deviation. At the same time, the bonding of the concave-convex points by the adhesive can ensure the firmness after bonding and can easily break the bonding point to take out the contents. In this embodiment, the height of the protrusions 21, 22 is 1 mm, and the depth of the recesses 23, 24 is 1 mm. In this embodiment, the protrusions 21, 22 are diametrically opposed, that is, they are located at both ends of the diameter of the tube mouth 2. In this embodiment, the recesses 23, 24 are diametrically opposed, that is, they are located at both ends of the diameter of the tube mouth 2. In this embodiment, the protrusions 21, 22 and the recesses 23, 24 evenly divide the tube mouth 2 into four parts. In addition, the tube 1 is provided with a circular hole 31 at the bottom 3 of the tube, and the circular hole 31 is used for the sterilization medium to enter and exit the interior of the tube 1 after the two tubes 1 are relatively buckled. In this embodiment, the diameter of the circular hole 31 is 2.5mm to 3.0mm.

[0023] Combination Figure 4 The card 4 is a paper or plastic card printed with a sterilization chemical indicator. 150g / ㎡~250g / ㎡ paper or 150μm~250μm thick PVC is selected as the card material. The width of the card 4 is 5.5mm~6.0mm, and the length of the card 4 is 50mm~51mm.

[0024] The card 4 is printed with a sterilization chemical indicator color block 5 and a contrasting color block 6, wherein the color of the sterilization chemical indicator color block 5 will change, and the contrasting color block 6 is the color of the sterilization chemical indicator after sterilization. After sterilization, by checking whether the sterilization chemical indicator color block 5 remains consistent with the color of the contrasting color block 6 after the color change, you can quickly know whether the sterilization effect meets the requirements. In addition, the card 4 is provided with a printing area 7 for marks and text descriptions.

[0025] Back to Figure 1 The inner length of the two tubes 1 is close to the length of the card 4, and the inner diameter of the two tubes 1 is slightly larger than the width of the card 4, so that the card 4 can be loaded into the two tubes 1 and relatively fixed. During the sterilization process, the sterilization medium enters and exits through the circular hole 31, and the position of the card 4 and the surrounding space are relatively stable, not affected by the density of the load, etc., and the probability of deviation is less, so the test result is more stable and accurate.

[0026] The above is only a preferred embodiment of the utility model, and is not intended to limit the scope of the utility model. The above embodiments of the utility model can also be modified in various ways. That is, all simple, equivalent changes and modifications made according to the claims and the contents of the specification of the utility model application fall within the scope of protection of the claims of the utility model patent. The conventional technical contents are not described in detail in the utility model.
