Description

Technical Field

[0001] This utility model relates to the field of biological indicator pressing devices, and in particular to a pressing tool. Background Technology

[0002] Biological indicators are special microbial products that have definite and stable tolerance to specific sterilization procedures. They can be used to confirm the performance of sterilization equipment, develop and establish sterilization processes for specific items, monitor the sterilization effect of production processes, and also be used to verify and evaluate the sterilization effect of isolation systems and cleanrooms.

[0003] Existing self-contained hydrogen peroxide sterilization biological indicators cannot completely immerse the carrier inside the liquid when pressed manually or with simple tools, or are prone to fatigue during prolonged manual pressing. Furthermore, they cannot completely prevent the manual person from completely isolating themselves from the substances contained in the indicator, thus compromising the safety of manual operation. Utility Model Content

[0004] The purpose of this invention is to provide a pressing tool that improves the convenience and safety of indicator pressing.

[0005] To solve the above-mentioned technical problems, this utility model provides a pressing fixture, including a base, a fixed seat on the base, and a connecting plate on the upper side of the base. A pressing rod is raised and lowered at the connecting plate. The fixed seat has a placement groove for placing an indicator, and the pressing rod and the placement groove are coaxially arranged so that the indicator is pressed when the pressing rod descends.

[0006] Furthermore, a sliding groove is provided at the connecting plate, and the pressure rod is movable in the sliding groove.

[0007] Furthermore, a spacer is provided at the connecting plate, and the spacer is fitted around the outer periphery of the pressure rod.

[0008] Furthermore, an elastic element is provided between the pressure rod and the connecting plate, and one end of the elastic element is located inside the spacer sleeve.

[0009] Furthermore, a pressure cap is provided at one end of the pressure rod near the fixed base, and the pressure cap corresponds to the end of the indicator.

[0010] Furthermore, the pressure cap surface has a rubber cap or suction cup.

[0011] Furthermore, a column connects the connecting plate to the base.

[0012] Furthermore, the base has a bottom pad on its underside.

[0013] The beneficial effects of this utility model are as follows: When it is necessary to press the indicator so that the carrier inside the indicator falls into the liquid, the indicator is placed in the placement groove, and the indicator is firmly placed on the base and located below the pressure rod by the fixing seat. Then, by pressing the pressure rod, the pressure rod is lowered and pushes the end of the indicator, so that the carrier inside the indicator falls into the liquid, thereby improving the convenience of pressing the indicator. Moreover, since no direct manual contact is required during the pressing process, the safety of the pressing process can be greatly improved. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0022] Those skilled in the art should understand that, in the disclosure of this utility model, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this utility model.

[0023] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0024] like Figures 1-6 The present invention provides a pressing fixture, including a base 1, a fixed seat 2 disposed on the base 1, and a connecting plate 3 disposed on the upper side of the base 1. A pressing rod 4 is provided at the connecting plate 3 for lifting. A placement groove 6 for placing an indicator 5 is provided in the fixed seat 2, and the pressing rod 4 and the placement groove 6 are coaxially arranged so that the indicator 5 is pressed when the pressing rod 4 descends.

[0025] When it is necessary to press the indicator to release the carrier inside into the liquid, place the indicator in the placement slot, secure it on the base and below the pressure rod using the fixing seat, and then press the pressure rod to lower it and push the end of the indicator, causing the carrier inside to fall into the liquid. This improves the convenience of pressing the indicator, and since no direct human contact is required during the pressing process, it greatly enhances the safety of the indicator pressing process.

[0026] In one embodiment of this solution, a groove is provided at the connecting plate, and the pressure rod is movable in the groove so that the groove limits the movement trajectory of the pressure rod.

[0027] The indicator used in this solution has a liquid inside and an aluminum foil seal on top of the liquid. A carrier is loaded on the top of the aluminum foil seal. By pressing the cap at the top of the indicator, the carrier on the top of the aluminum foil seal is pushed and thus breaks through the aluminum foil seal, allowing the carrier to fall into the liquid below after passing through the aluminum foil seal. The specific structure and usage of this indicator have been disclosed in the patent "CN212247028U A self-contained biological indicator container", and will not be described in detail here.

[0028] Preferably, a spacer 7 is provided at the connecting plate 3, and the spacer 7 is sleeved on the outer periphery of the pressure rod 4.

[0029] Specifically, the spacer sleeve guides and protects the outer periphery of the pressure bar, improving the stability of the pressure bar's lifting and lowering, and ensuring the accurate pressing position of the pressure bar on the indicator.

[0030] Preferably, an elastic element 8 is provided between the pressure rod 4 and the connecting plate 3, and one end of the elastic element 8 is located inside the spacer 7.

[0031] Specifically, the elastic element assists in resetting the pressure rod, so that after the pressure rod presses the indicator, the elastic element can push the pressure rod back to the initial position, which facilitates subsequent pressing operations. In addition, the end of the elastic element is protected by a spacer, which increases the stability of the elastic element's guiding effect on the pressure rod.

[0032] The elastic element can be a spring structure.

[0033] Preferably, a pressure cap 9 is provided at one end of the pressure rod 4 near the fixed base 2, and the pressure cap 9 corresponds to the end of the indicator 5.

[0034] Specifically, when pressing the lever, the end of the indicator is aligned and pressed using the pressure cap to ensure the pressing effect of the lever and effectively increase the pressing area at the end of the lever, thereby improving the pressing effect.

[0035] Preferably, the surface of the pressure cap 9 has a rubber cap 10 or a suction cup.

[0036] Specifically, when a rubber cap is used on the pressure cap surface, the indicator end is also made of rubber material. Through the adhesion generated by pressing the rubber materials together, when the pressure rod rises and resets, the indicator can be lifted by the adhesive of the rubber cap, thus making it easy to remove the indicator from the placement slot.

[0037] When the end of the indicator is difficult to adhere and lift, a suction cup can be installed on the surface of the pressure cap. When the pressure rod rises and resets, the end of the indicator is adsorbed by the suction cup, and then the indicator is lifted by the suction cup, so as to ensure that the indicator can be easily removed.

[0038] Preferably, a column 11 is connected between the connecting plate 3 and the base 1.

[0039] Specifically, the connecting plate is stabilized by the column, thereby improving the lifting stability of the pressure rod and ensuring the relative position stability between the pressure rod and the fixed seat.

[0040] Preferably, the base 1 has a bottom pad 12 on its lower side to prevent slippage and stabilize the lower side of the base, thereby improving the overall stability during the indicator pressing operation.

[0041] In one embodiment of this solution, the base pad may be a structure such as a mat or a rubber pad.

[0042] This utility model is not limited to the above-described preferred embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in their shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this utility model.
