Description

Technical Field

[0001] This application relates to the technical field of biological indicators, and particularly to a self - contained biological indicator manual capping and tube - clamping tooling. Background Art

[0002] With the development and maturity of biological indicator technology, the verification of sterilization effect has gradually changed from the original weekly verification to daily verification, and even more and more sterilization institutions have started batch - by - batch verification. Since the self - contained biological indicator encapsulates special spores, the culture medium for spore growth recovery, and other auxiliary materials as a whole, and is sterilized together with the object to be sterilized, and directly cultured after sterilization without operations such as inoculation, it reduces the risk of bacterial contamination during the process and greatly improves the convenience of sterilization effect verification. However, since the self - contained biological indicator needs to separate the culture medium and spores before sterilization, most of the culture media are encapsulated in straight - tube ampoules. After sterilization, the ampoules need to be broken to make the culture medium fully contact with the spores. And such indicators often have a channel for the sterilization medium to enter the interior, which needs to be closed during the culture process to prevent evaporation loss of the culture medium. Most of the indicators use the form of being sealed by pressing a cap. Therefore, two actions need to be performed after the sterilization of such self - contained biological indicators, namely, ampoule breaking and cap pressing, which greatly affects the convenience during batch verification.

[0003] Therefore, there is an urgent need for a tooling that can achieve batch processing of capping and tube - clamping of multiple indicators at low cost to solve the problems existing in the prior art. Utility Model Content

[0004] The purpose of this application is to provide a self - contained biological indicator manual capping and tube - clamping tooling for the above - mentioned problems existing in the prior art.

[0005] To achieve the above - mentioned application purpose, the following technical solutions are adopted in this application: A self - contained biological indicator manual capping and tube - clamping tooling includes:

[0006] A base, provided with a plurality of installation grooves for installing biological indicators. An opening is provided on one side of each installation groove facing the tube - breaking moving block for the tube - breaking moving block to enter and squeeze the biological indicator;

[0007] A tube - breaking moving block, cooperating with the base, for squeezing the outer shell of the biological indicator to break the straight - tube ampoule inside the biological indicator;

[0008] A return spring, arranged between the tube - breaking moving block and the base;

[0009] A tube - breaking shaft, provided with a crushing cam and a capping cam along its length direction. By driving the crushing cam to rotate, the tube - breaking moving block is driven to squeeze the biological indicator;

[0010] The gland swing rod is rotatably connected to the base and abuts against the gland cam. It can be driven by the gland cam to rotate after or simultaneously with the breaking of the ampoule straight tube to press down and close the cap of the biological indicator.

[0011] The rotary tension spring is arranged between the gland swing rod and the base and is used for the reset of the gland swing rod.

[0012] The manual pressing swing rod is connected to the tube-breaking shaft and is used to drive the tube-breaking shaft to rotate.

[0013] Further, a plurality of avoidance grooves are provided on the gland swing rod, and the avoidance grooves are used to avoid the breaking cam.

[0014] Further, a pull pin is provided at each of the left and right ends of the base, and a corresponding pull hole is provided on the gland swing rod. The rotary tension spring is installed through the pull pin and the pull hole.

[0015] Further, a flipping positioning pin is provided on the left side surface and / or the right side surface of the base to limit the rotation angle stroke of the manual pressing swing rod.

[0016] Further, a guide shaft is provided on the base and is matched with the tube-breaking moving block to guide the movement of the tube-breaking moving block, and the return spring is installed on the outer ring of the guide shaft.

[0017] Further, a taper angle is provided at one end of the tube-breaking moving block facing the installation groove.

[0018] Further, the tube-breaking moving block is located in the middle area in the height direction of the installation groove.

[0019] Further, the breaking cam and the gland cam are arranged at intervals.

[0020] Further, the front end of the gland swing rod is the gland part, the rear end is the passive part, and the middle is the connecting part. The cap of the biological indicator is pressed down and closed through the gland part, the gland swing rod abuts against and cooperates with the gland cam through the passive part, and the gland swing rod is rotatably cooperated with the base through the connecting part.

[0021] Further, the installation grooves are evenly arranged at intervals along the length direction of the base.

[0022] Compared with the prior art, the present application has the following beneficial effects:

[0023] 1. This tooling can simultaneously realize the two key actions of breaking the ampoule tube of the biological indicator and pressing the cap tightly, greatly improving the operation efficiency. Especially when processing multiple indicators in batches, the advantage is more obvious. For example, in a sterilization laboratory that needs to process a large number of self - contained biological indicators, in the past, the operations of breaking the ampoule tube and pressing the cap tightly had to be carried out separately, which was not only cumbersome but also time - consuming. However, using this tooling can complete these two actions at one time, greatly saving time and labor costs.

[0024] 2. Through ingenious structural design, such as the crushing cam and gland cam on the pipe-breaking shaft, and components such as the pipe-breaking moving block and gland swing rod that cooperate with them, this tooling realizes the integration of functions, has a compact structure, and occupies a small space. Taking a small sterilization workroom as an example, more of this tooling can be placed in the limited space, improving the utilization rate of the workplace.

[0025] 3. This tooling adopts manual operation and does not require the support of complex electrical or automated equipment, reducing costs and maintenance difficulties. For example, some small sterilization institutions with limited budgets can obtain an efficient sterilization effect verification tool with a low investment. Multiple evenly spaced mounting grooves are provided on the base, which can process multiple biological indicators simultaneously, meeting the need for batch processing and further improving work efficiency. Assuming that on a large-scale sterilization production line, multiple biological indicators can be processed at one time, the production progress will be greatly accelerated. The end of the pipe-breaking moving block facing the mounting groove is provided with a taper angle, which can more accurately squeeze the outer shell of the biological indicator, improving the success rate and effect of the ampoule straight pipe breaking.

[0026] 4. The pipe-breaking moving block is located in the middle area in the height direction of the mounting groove, making the extrusion force more uniform and ensuring the stability and consistency of the ampoule straight pipe breaking. The crushing cam and gland cam are arranged at intervals, enabling the two actions to proceed in an orderly manner without interference, improving the reliability and stability of the tooling. The special structural design of the gland swing rod, including the gland part, passive part, and connecting part, can effectively realize the action of pressing down and closing the cap plug, and cooperate closely with other components with smooth actions. The setting of the return spring and rotary tension spring ensures that the pipe-breaking moving block and gland swing rod can be reset in time after completing the action, preparing for the next operation and improving the continuous working ability of the tooling. The setting of the guide shaft provides precise guidance for the movement of the pipe-breaking moving block, ensuring the accuracy and stability of the extrusion action, and further improving the performance and reliability of the tooling.

Therefore, the above terms should not be construed as limiting the present application.

[0035] As Figures 1-4 shown, the self-contained biological indicator manual gland clamping and tube-clamping tooling includes:

[0036] A self-contained biological indicator 2 manual gland clamping and tube-clamping tooling includes a base 1, a tube-breaking moving block 3, a return spring 4, a tube-breaking shaft 5, a gland swing rod 7, a rotary tension spring 10, and a manual pressing swing rod 9.

[0037] A plurality of installation grooves 11 are evenly spaced along the length direction of the base 1, and an opening is provided on one side of each installation groove 11 facing the tube-breaking moving block 3. The installation grooves 11 are used to install the biological indicator 2, and the openings are for the tube-breaking moving block 3 to enter and squeeze the biological indicator 2.

[0038] The tube-breaking moving block 3 cooperates with the base 1 and is located in the middle area in the height direction of the installation groove 11. One end of the tube-breaking moving block 3 facing the installation groove 11 is provided with a taper angle for squeezing the outer shell of the biological indicator 2 so that the ampoule straight tube 24 inside the biological indicator 2 is broken. The return spring 4 is arranged between the tube-breaking moving block 3 and the base 1. A guide shaft 12 is provided on the base 1 and cooperates with the tube-breaking moving block 3. The return spring 4 is installed on the outer circle of the guide shaft 12 to guide and reset the movement of the tube-breaking moving block 3.

[0039] The pipe-breaking shaft 5 is provided with a plurality of pipe-breaking cams 6 and gland cams 8 along its own length direction, and the pipe-breaking cams 6 and the gland cams 8 are arranged at intervals. By driving the rotation of the pipe-breaking cam 6, the pipe-breaking moving block 3 is driven to extrude the biological indicator 2.

[0040] The front end of the gland swing rod 7 is a gland part 71, the rear end is a driven part 72, and the middle is a connecting part 73. The gland swing rod 7 is rotatably connected to the base 1 through the connecting part 73, and the driven part 72 is in abutting cooperation with the gland cam 8. A plurality of avoidance grooves are provided on the driven part 72 of the gland swing rod 7 for avoiding the pipe-breaking cams 6. After or simultaneously with the breaking of the ampoule straight pipe 24, the driven part 72 of the gland swing rod 7 can rotate under the drive of the gland cam 8, and the cap plug 23 of the biological indicator 2 is pressed down and closed by the gland part 71.

[0041] A pull pin 13 is provided at both the left and right ends of the base 1, and corresponding pull holes are provided on the driven part 72 of the gland swing rod 7. The rotary tension spring 10 is installed between the gland swing rod 7 and the base 1 through the pull pin 13 and the pull holes for the reset of the gland swing rod 7. Among them, this rotary tension spring 10 has another function. After the gland swing rod 7 is reset, the rotary tension spring 10 will pull the driven part 72, so that the gland part 71 tilts up and will no longer interfere with the entry and exit of the indicator from the installation groove 11, so as to facilitate the placement or taking of the indicator.

[0042] The manual pressing swing rod 9 is connected to the pipe-breaking shaft 5 and is used to drive the rotation of the pipe-breaking shaft 5 through manual operation. Overturning positioning pins 14 are provided on both the left side and the right side of the base 1 to limit the rotation angle stroke of the manual pressing swing rod 9.

[0043] As Figure 5 shown, the structure of each self-contained biological indicator 2 includes a cap body 21, a cup body 22, a cap plug 23 and an ampoule straight pipe 24. Among them, the ampoule straight pipe 24 is made of glass, and the others are made of plastic. In this scheme, the plastic cup body 22 is extruded to indirectly crush the glass ampoule straight pipe 24. After the pipe-breaking is completed, the cap plug 23 is pressed down to close, preventing the evaporation of the internal culture medium.

[0044] Embodiment 2

[0045] First, a plurality of self-contained biological indicators 2 are respectively placed in the installation grooves 11 of the base 1. At this time, the ampoule straight pipe 24 of the biological indicator 2 is located at the corresponding position of the pipe-breaking moving block 3, and the cap plug 23 is located below the gland part 71 of the gland swing rod 7.

[0046] The operator holds the manual pressing swing rod 9 and applies pressure to drive the rotation of the pipe-breaking shaft 5. The pipe-breaking cam 6 on the pipe-breaking shaft 5 rotates accordingly, and the pipe-breaking moving block 3 is pushed to move along the guide shaft 12 towards the installation groove 11.

[0047] Since one end of the pipe-breaking moving block 3 facing the installation groove 11 is provided with a taper angle, it can accurately extrude the outer shell of the biological indicator 2, causing the inner ampoule straight pipe 24 to break.

[0048] When the ampoule straight pipe 24 breaks, or after it breaks, the gland cam 8 on the pipe-breaking shaft 5 rotates and contacts the passive part 72 of the gland swing rod 7, driving the gland swing rod 7 to rotate around the connecting part 73 with the base 1. The gland part 71 at the front end of the gland swing rod 7 presses down the cap plug 23 of the biological indicator 2 to close it, achieving sealing.

[0049] After the operation is completed, release the manual pressing swing rod 9, and the return spring 4 pulls the pipe-breaking moving block 3 back to the initial position, and the rotary tension spring 10 pulls the gland swing rod 7 back to the initial position, preparing for the next round of operation.

[0050] The parts not detailed in this application are prior art, so this application does not elaborate on them.

[0051] It can be understood that the term "one" should be understood as "at least one" or "one or more". That is, in one embodiment, the number of one element can be one, while in other embodiments, the number of this element can be multiple. The term "one" cannot be understood as a limitation on the quantity.

[0052] Although this application uses more terms such as the base 1, biological indicator 2, pipe-breaking moving block 3, return spring 4, pipe-breaking shaft 5, crushing cam 6, gland swing rod 7, gland cam 8, manual pressing swing rod 9, rotary tension spring 10, installation groove 11, guide shaft 12, pull pin 13, over-turning positioning pin 14, cap body 21, cup body 22, cap plug 23, ampoule straight pipe 24, gland part 71, passive part 72, connecting part 73, etc., it does not exclude the possibility of using other terms. Using these terms is only to more conveniently describe and explain the essence of this application; interpreting them as any additional limitation is contrary to the spirit of this application.

[0053] This application is not limited to the above best implementation mode. Anyone can obtain other various forms of products under the inspiration of this application. However, no matter what changes are made in its shape or structure, as long as it has a technical solution identical or similar to this application, it falls within the protection scope of this application.
