Description

Technical Field

[0001] The invention belongs to the technical field of sterilization detection equipment, in particular to a clamping and fixing device and its application in pressure steam sterilization. Background Art

[0002] For high-pressure sterilization containers, the set values ​​include sterilization temperature and sterilization time. The sterilization temperature is verified by related products, such as sterilization indicator cards, 3M sterilization indicator tape, etc., but there is no related product or method to confirm the sterilization time.

[0003] The patent with application number CN201821176942.5 discloses a clamping and fixing device for a sterilization indicator, including a base, a clamping plate and a lead screw. A pair of anti-slip pads are fixedly connected at both ends of the bottom surface of the base, and a pair of support plates are vertically fixedly connected at one end of the upper surface of the base. The two support plates are horizontally fixedly connected to a limit plate at one end away from the base, and a first groove is provided inside the base just below the limit plate. The above scheme can flexibly and conveniently clamp and fix the sterilization indicator bottle by installing clamping plates on two movable movable plates, and the positioning groove on the limit plate can limit the position of the reagent bottle and play a supporting role, so as to avoid the reagent bottle falling off due to the looseness of the clamping plate during clamping. In addition, the lead screw is used to move the movable plate, and two bidirectional threads are arranged on the movable plate to facilitate the relative movement of the two movable plates, so as to achieve a flexible clamping function. The entire clamping and fixing device is easy to use, and the clamping is more stable, so that the entire device can be easy to carry. The above-mentioned prior art only realizes the clamping of the sterilization indicator bottle, and cannot accurately identify the sterilization time.

[0004] In the process of detecting and judging the sterilization time, it is necessary to connect the container containing the solution to the device. During this process, it is easy for the container to collide and be damaged with the bottom of the clamping device. In addition, when the container clamp is in use, there is a gap between the container clamp and the container, causing the container to shake during the sterilization process, affecting the recognition result.

[0005] Therefore, in order to solve the above technical problems, the present invention proposes a clamping and fixing device and its application in pressure steam sterilization. Summary of the invention

[0006] The purpose of the present invention is to solve the above problems and provide a clamping and fixing device and its application in pressure steam sterilization, which has the advantages of being able to accurately determine the sterilization time and ensure the safety of the container.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example 1

[0022] like Figure 1 - Figure 7 As shown, this embodiment discloses a clamping and fixing device, including a sterilization device 1 for providing a sterilization space, wherein a plurality of limiting components 2 are movably provided in the sterilization device 1, wherein the number of the limiting components 2 is greater than or equal to two, ensuring that a control group of the limiting components 2 exists during sterilization, and a container 3 is plugged into the limiting component 2, wherein the container 3 is filled with a liquid for testing, and when in use, the limiting component 2 is connected to the sterilization device 1 by plugging the container 3 into the limiting component 2, and the stability of the limiting component 2 in the sterilization device 1 is ensured.

[0023] The container 3 includes but is not limited to a test tube and a beaker.

[0024] The limiting assembly 2 includes a limiting portion 201, one end of which is connected to a clamping assembly 4 for constraining the position of the upper portion of the container 3, the end of the limiting portion 201 away from the clamping assembly 4 is connected to a connecting portion 202, the end of the connecting portion 202 away from the clamping assembly 4 is connected to a clamping portion 203, the end of the clamping portion 203 away from the connecting portion 202 is connected to a heating portion 204 for heating the solution in the container 3, and the end of the heating portion 204 away from the clamping portion 203 is connected to a bearing portion 205, so as to During the plugging process of the container 3 and the limiting component 2, the container 3 first passes through the clamping component 4 and then enters the area of ​​the limiting component 2, and passes through the limiting part 201, the connecting part 202, the clamping part 203, the heating part 204 and the supporting part 205 in sequence. The bottom of the container 3 contacts the bottom of the supporting part 205, and the container 3 is heated by the heating part 204. The heating temperature of the heating part 204 on each limiting component 2 can be freely adjusted to ensure that the sterilization rate of the solution in the container 3 at different temperatures can be identified during use.

[0025] In order to ensure the stability of the container 3 when it is connected to the limiting component 2, the clamping component 4 includes a plurality of elastic plates 401, and the plurality of elastic plates 401 are distributed in a circular array on the limiting component 2. An movable block 402 is connected to one end of the elastic plate 401 close to the limiting portion 201, and the movable block 402 is movably connected to the end face of the limiting portion 201. That is, when the elastic plate 401 is subjected to force, relative displacement will occur between the movable block 402 and the limiting portion 201, and the angle between the movable block 402 and the elastic plate 401 will be changed.

[0026] It should be noted that the cross-sectional shape of the elastic plate 401 includes but is not limited to a “√” shape, and when the elastic plate 401 is connected to the movable block 402, the elastic plate 401 is in an inclined state, ensuring that the elastic plate 401 can restrict and clamp the container 3 during use to maintain the stability of the container 3.

[0027] Furthermore, in order to ensure that the container 3 moves stably on the clamping assembly 4 and reduce the collision and damage between the bottom of the container 3 and the bearing part 205 caused by improper operation of the staff, the clamping assembly 4 also includes a reset spring 403, one end of the reset spring 403 is connected to the movable block 402, and the other end is connected to the limiting part 201. When the container 3 contacts the elastic plate 401, it will drive the elastic plate 401 to deflect and contact the tube wall of the container 3. At the same time, as the container 3 continues to move toward the limiting assembly 2, it will drive the elastic plate 401 to continue to deflect, and drive the movable block 402 to move on the limiting part 201, so as to extend the length of the reset spring 403, thereby ensuring that the moving speed of the container 3 on the limiting assembly 2 is stable and will not collide with the bearing part 205 and be damaged.

[0028] It should be noted that the contact portion between the elastic plate 401 and the container 3 is provided with an anti-slip sheet, and since the tube wall of the container 3 is in a smooth state, the anti-slip sheet can only suppress the movement rate of the container 3, and cannot completely prevent the movement of the container 3. At the same time, since the container 3 contains a solution, the anti-slip sheet will cause the elastic plate 401 to slowly deflect as the container 3 moves, thereby driving the movable block 402 to move, causing the length of the return spring 403 to extend, thereby ensuring that the movement rate of the container 3 in the limiting component 2 is stable, thereby improving the safety of the container 3.

[0029] If necessary, in order to ensure the accuracy of identification and detection of the sterilization time, it is necessary to control the depth of the solution in the containers 3 of the same specifications to be the same, that is, the containers 3 are under the same gravity with each other, and then when the containers 3 move on the elastic plate 401, the volume of the solution in the container 3 can be identified according to the deflection angle of the elastic plate 401. When the deflection angles of the elastic plate 401 are the same, it means that the volume of the solution in the container 3 is the same. When the deflection angles of the elastic plate 401 are different, it means that the volume of the solution in the container 3 is different, reminding the staff to adjust the solution in the container 3.

[0030] Furthermore, in order to ensure that the placement space of the container 3 in the limiting component 2 is stable and the container 3 does not shake or fall in the limiting component 2, a vertical storage cavity 6 for placing the container 3 is opened on the limiting component 2, and a detection cavity 2031 is opened in the clamping portion 203, and the detection cavity 2031 is connected to the storage cavity 6. After the container 3 passes through the elastic plate 401, the bottom and wall of the container 3 will enter the storage cavity 6, and pass through the detection cavity 2031 to collide with the bearing portion 205. When the container 3 passes through the clamping component 4 and initially enters the storage cavity 6, the user can release the container 3 at this time, so that the container 3 slides freely into the storage cavity 6, thereby reducing the installation time of the container 3 by the user.

[0031] Furthermore, in order to ensure that the limiting component 2 can meet the stable use of containers 3 of different specifications, a plurality of connecting cavities 2011 are opened in the limiting portion 201, and the plurality of connecting cavities 2011 are evenly distributed on the limiting portion 201 in a circular array, and the plurality of connecting cavities 2011 are connected with a stabilizing component 5. In the present embodiment, the number of the connecting cavities 2011 is preferably four, and the stabilizing component 5 includes a telescopic rod 502 for controlling the position of the card plate 501, one end of the telescopic rod 502 is connected to the cavity wall of the connecting cavity 2011, and the end of the telescopic rod 502 away from the connecting cavity 2011 is connected with a card plate 501, and the card plate 501 can be hidden. Hidden in the connecting cavity 2011, it is ensured that the container 3 will not be interfered by the card plate 501 when moving in the storage cavity 6, wherein the card plate 501 is in a fan-shaped state, and the storage cavity 6 can be covered by the cooperation of the four card plates 501. At the same time, when the container 3 is placed in the storage cavity 6, the card plate 501 is controlled to move by the telescopic rod 502, so that the card plate 501 is in conflict with the tube wall of the container 3, ensuring the stability of the container 3 in the storage cavity 6. At the same time, the elastic plate 401 can control the length of the telescopic rod 502, thereby realizing the control of the position of the card plate 501, ensuring that the card plate 501 does not interfere with the movement of the container 3.

[0032] When the container 3 is not in the storage cavity 6, the clamping plate 501 can seal the storage cavity 6 to prevent debris from entering the storage cavity 6 and affecting the placement of the container 3, thereby ensuring stable use of the clamping and fixing device.

[0033] Furthermore, when the container 3 is in the sterilization process, a sterilization indicator is added, and the color in the container 3 can change with the occurrence of sterilization conditions, and then the sterilization conditions in the container 3 can be judged by identifying the color change in the container 3. A light capturing plate 8 for capturing the color in the container 3 is connected to the cavity wall of the detection cavity 2031, and a color sensor is connected to the light capturing plate 8. The color sensor can identify and judge the light captured by the light capturing plate 8, so that the color in the container 3 can be quickly identified to ensure the accuracy of the sterilization time.

[0034] Furthermore, in order to ensure the sterilization time of the sterilization indicator at different temperatures, a plurality of heating blocks 9 are connected to the cavity wall of the detection cavity 2031, and the heating blocks 9 and the light capturing plates 8 are staggered on the detection cavity 2031. In the present invention, the heating blocks 9 are preferably electric heating components. Through the mutual cooperation between the heating blocks 9 and the heating part 204, it is ensured that the solution in the container 3 can be heated evenly, thereby meeting the sterilization requirements of the sterilization indicator.

[0035] Furthermore, a plurality of temperature sensors 7 are connected to the cavity wall of the storage cavity 6. The temperature sensors 7 are located on the connecting portion 202. The temperature in the container 3 is identified and detected by the temperature sensors 7 to ensure the accuracy of the sterilization time.

[0036] Furthermore, the sterilization device 1 includes a sterilization box 101, a sterilization chamber 102 is opened in the sterilization box 101, and a plurality of support seats 103 are connected to the sterilization chamber 102. In the present embodiment, the support seat 103 is composed of a plurality of cross bars, so that the clamping portion 203 in the limiting component 2 is engaged with the support seat 103 to ensure the stability of the container 3 in the sterilization chamber 102, and a light emitter is connected to the corresponding position of the sterilization chamber 102 and the limiting component 2, and the light of the light emitter is irradiated into the container 3, and then the judgment is made by the color of the reflected light in the container 3.

[0037] At the same time, in this embodiment, the shape of the support seat 103 can also be a disc, and a groove for the clamping part 203 to be engaged is opened on the disc to fix the limiting component 2. At the same time, during the sterilization process, the support seat 103 can be controlled to rotate, prompting the solution in the container 3 to rotate, thereby increasing the sterilization time.

[0038] Specifically, the use of sterilization indicators that indicate different sterilization temperatures and times is usually achieved by using chemical substances to undergo chemical reactions of varying degrees under different temperature and time conditions. Some indicators based on changes in enzyme activity and color changes of chemical substances can be designed to monitor the sterilization process. When exposed to a specific temperature-time combination, their chemical or physical properties will change, thereby showing different colors or state changes.

[0039] When the device is used, first add a properly measured solution into the container 3, move the container 3 to contact and slide relative to the clamping component 4, and during the movement of the container 3, the stabilizing component 5 is hidden in the connecting cavity 2011 under the action of the clamping component 4 to ensure that the container 3 and the limiting component 2 are stably plugged in, and at the same time, add the sterilizing agent and its indicator, and after the container 3 is connected to the limiting component 2, move the limiting component 2 to connect with the sterilization device 1 to realize the identification of the sterilization condition in the container 3.

[0040] After the container 3 contacts the clamping assembly 4, it first contacts the elastic plate 401, and as the container 3 moves, the container 3 is prompted to contact the anti-slip sheet on the elastic plate 401, and as the container 3 continues to move, the container 3 is driven to deflect at an angle. Due to the influence of the interaction force between the container 3 and the anti-slip sheet, when the container 3 moves into the storage cavity 6, the elastic plate 401 drives the movable block 402 and the limiting portion 201 to slide relative to each other, driving the length of the return spring 403 to stretch, ensuring that the movement speed of the container 3 in the storage cavity 6 is stable and will not cause damage to the container 3. At the same time, it also allows the user to adjust other operating processes without the need to continuously control the container 3, thereby improving work efficiency.

[0041] Furthermore, when the elastic plate 401 drives the movable block 402 to move, the telescopic rod 502 drives the clamping plate 501 to move into the connecting cavity 2011 , ensuring that the movement of the container 3 is not interfered with.

[0042] With the relative sliding between the container 3 and the elastic plate 401 and the movement of the elastic plate 401 and the movable block 402, the stability of the container 3 when in contact with the bearing portion 205 is ensured. When the container 3 moves in the storage cavity 6, the sterilization reagent and its indicator are added to the container 3, and the limiting component 2 is moved to contact and limit the support seat 103 to ensure that the container 3 is stably connected in the sterilization cavity 102.

[0043] After the container 3 completely contacts the bearing part 205, the elastic plate 401, under the action of the return spring 403 and its own elastic force, prompts the movable block 402 to move to the side close to the container 3 under the elastic force of the return spring 403, and the elastic plate 401 slides relatively with the tube wall of the container 3. At this time, the container 3 does not displace with the storage chamber 6, that is, the elastic plate 401 is elastically reset to maintain the clamping restriction on the container 3, and adjusts the telescopic rod 502 to drive the card plate 501 to move, prompting the end of the card plate 501 away from the telescopic rod 502 to contact the tube wall of the container 3, ensuring that the position of the container 3 in the sterilization chamber 102 is stable, and while the elastic plate 401 and the card plate 501 clamp and fix the container 3, the card plate 501 can also block the light in the storage chamber 6, reduce the interference of external light on the color sensor, and improve the capture sensitivity of the color sensor to the color of the solution in the container 3, ensuring that the detection error will not cause significant interference to the detection result.

[0044] The light emitter is controlled to start, causing the light to pass through the container 3 and the solution in the container 3, reflecting the light onto the light capturing plate 8 and being recognized by the color sensor, and heating the solution in the container 3 through the heating part 204 and the heating block 9. The time when the color in the container 3 changes is judged by the color sensor, which is used to judge the difference in sterilization time of the sterilizer at different temperatures, thereby determining the sterilization time of the sterilizer when it is used.

[0045] It should be noted that a magnetic interface connected to the clamping portion 203 is provided on the support seat 103. When the clamping portion 203 moves to the target position, an electrical connection is formed between the support seat 103 and the limiting component 2, and the working status of the limiting component 2 and the identified situation can be received through the sterilization box 101. Example 2

[0046] The present embodiment discloses an application of a clamping and fixing device in pressure steam sterilization. By using a sterilization indicator in a pressure steam environment and identifying and judging the color change of the sterilization indicator, the sterilization time of the sterilizer is determined. In addition, the clamping effect of the clamping and fixing device on the container 3 can improve the detection effect of the container 3 in pressure steam sterilization, and ensure the safety and stability of the container 3 during the clamping process.
