Abstract
Description
Technical Field
[0001] The invention relates to the technical field of rubber dam clip storage, in particular to a rubber dam clip storage box for disinfection. Background Art
[0002] Rubber dam isolation technology effectively isolates the affected tooth from the oral environment. It provides excellent moisture-proofing, prevents the accidental swallowing and aspiration of instruments and foreign objects, protects soft tissue from scratches and burns, and prevents saliva and microbial contamination of the surgical area, thereby improving clinical efficiency. With the development and advancement of technology, rubber dam isolation technology has become the most effective isolation method and an essential component of outpatient dental care.
[0003] The rubber dam clamp is a core device used to fix the rubber dam cloth and isolate the affected teeth in oral treatment (such as Figure 1 As shown in the figure, they must be sterilized at high temperature and high pressure before reuse. Because rubber dam clamps are available in various types (e.g., anterior tooth clamps, premolar clamps, and molar clamps) in clinical treatment, they must be stored and managed by category to avoid confusion. Furthermore, during sterilization and transportation, the instruments must be protected from collision and wear to extend their service life.
[0004] At present, the disinfection and storage of rubber dam clips in clinical practice mainly rely on universal containers. Typical solutions include: (1) Paper-plastic packaging bags: A single rubber dam clip is packaged in a plastic packaging bag with a breathable paper surface for disinfection. This method requires unpacking and taking out the equipment one by one, which is cumbersome and cannot visually identify the instrument model; the stacking of packaging bags during transportation can easily cause the instruments to be squeezed and deformed, and their reusability is poor. (2) Multi-compartment needle box: The universal compartment structure of the existing needle box is used to store rubber dam clips. However, the compartment size and fixing method of the needle box are not designed for the morphological characteristics of the rubber dam clip (such as the beak clamping structure). The instruments are loose in the compartment and are prone to shaking and collision during transportation; and the box body lacks a ventilation channel design that is suitable for disinfection conditions, which easily forms a steam penetration blind spot.
[0005] Therefore, the prior art has the following technical problems:
[0006] ① Inefficient classification management: Universal containers lack targeted compartmentalization, and different types of rubber dam clips are mixed together, requiring repeated searching for them when needed, which prolongs preoperative preparation time.
[0007] ② Insufficient fixation reliability: There is no dedicated fixing structure in the existing container, and the shaking of the equipment during transportation causes collision and wear, which reduces the service life of the equipment;
[0008] ③ Limited disinfection effect: The layout of the air vents in the sealed container is unreasonable, and high-temperature steam cannot evenly penetrate into the instrument clamping structure (such as the blind hole in the beak), resulting in dead corners for disinfection.

[0021] One or more technical solutions provided in the embodiments of the present invention have at least the following technical effects or advantages:
[0022] 1. In the rubber dam clip storage box, the bottom box serves as the basic supporting component of the entire storage box. The interior of the box is divided into multiple accommodating cavities by partitions, which can classify and place the rubber dam clips for easy management and retrieval. The ventilation holes on the partitions and the first and second through holes staggered on the front and back of the box body, together with the 180-degree rotation of the box cover, can realize the switching between the disinfection mode (the through holes are aligned to facilitate the entry of disinfection steam) and the storage mode (the through holes are staggered and closed to prevent contaminants from entering the box). The fixing component consists of a base and a snap-fit pin. The base is inserted into the bottom of the box to achieve both a fixing function and an anti-slip function through the protruding structure at the lower end. After the snap-fit pin is inserted into the base, it expands to fix the beak of the rubber dam clip to prevent the rubber dam clip from shaking. Compared with the existing technology, the present invention sets up classification compartments to improve the efficiency of equipment management; the base and the snap-fit pin linkage structure are used to achieve a firm clamping of the rubber dam clip, damage prevention during transportation, and anti-slip of the storage box.
[0023] 2. The rubber dam clip disinfection storage box is equipped with a base inside, which can fix the rubber dam clip in the storage box. It can be easily operated with general tools such as tweezers, and does not require special tools such as rubber dam clamps. It can improve operational efficiency and reduce the shaking and wear of the rubber dam clip in the box during transportation, thereby reducing the damage rate of the rubber dam clip and extending its service life.
[0024] 3. The base is made of flexible material. The diameter of the shaft at the upper end of the base is slightly smaller than the diameter of the beak of the rubber dam clip, which makes it easy for the rubber dam clip to be inserted into the shaft. The diameter of the snap-fit nail is slightly larger than the diameter of the blind hole of the base, which can expand the shaft of the base and firmly clamp the rubber dam clip. This makes it convenient to take and place the rubber dam clip and firmly fix it. In addition, the shaft is made of flexible material and is compatible with a variety of rubber dam clips of similar sizes, with good versatility.
[0025] 4. A vent hole is located at the bottom of the base, which balances air pressure during insertion and removal of the fasteners, facilitating their insertion and removal. It also allows steam to enter during disinfection, disinfecting the deep blind holes and fasteners and eliminating blind spots. The base is easily disassembled and replaced independently if damaged, eliminating the need to scrap the entire box and saving costs.
[0026] 5. Two groups of through holes are provided on the front and rear ends of the box body and the box cover, and the projections of the two groups of through holes do not overlap. When the box cover is normally buckled, it is in a closed state, preventing aerosols, dust, microorganisms, etc. in the clinic from entering the box, and can be used for long-term storage; when the box cover and the box body are rotated 180 degrees relative to each other and buckled, the through holes are unobstructed, which can meet the ventilation requirements of the disinfection operation.
[0027] 6. The height of the partition is slightly lower than the height of the outer frame of the box. There is a gap between the partition and the box cover. The bottom of the partition is suspended in the air, leaving a gap between it and the bottom of the box body. The partition of the box body is provided with ventilation holes to ensure good ventilation during disinfection and ensure the disinfection effect. In addition, it can facilitate drainage during disinfection and cleaning, and can reduce corners and gaps that are easy to hide dirt.
[0028] Additional advantages of the present invention will be given in the description which follows, and in part will be obvious from the description which follows, or may be learned through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] It should be noted that the following detailed description is illustrative and is intended to further illustrate the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as commonly understood by those of ordinary skill in the art to which the present invention belongs. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.
[0039] Explanation of terminology: The beak refers to the clamp-like structure at the front of the rubber dam clamp that is used to clamp the tooth.
[0040] like Figure 2 As shown, this embodiment proposes a rubber dam clip storage box for disinfection, including a bottom box 2, a fixing component 3 and a box cover 4; Figure 3 As shown, the bottom box 2 includes a box body 21 and a partition 22. The partition 22 is installed in the box body 21 and divides the box body 21 into a plurality of accommodating cavities. The partition 22 is provided with vents 27 to connect adjacent accommodating cavities. The front and back of the box body 21 are respectively provided with first through holes 23 and second through holes 28 arranged in a staggered manner; Figure 4 As shown, the fixing assembly 3 includes a base 32 and a buckling pin 31. The base 32 is inserted into the bottom of the box and the lower end protrudes from the bottom of the box. The buckling pin 31 is inserted into the base 32 and expands and supports the base 32 on the beak 11 of the rubber dam clip 1; Figure 7 As shown, the box cover 4 is buckled onto the box body 21 , a third through hole 44 corresponding to the first through hole 23 is provided on the front of the box cover 4 , and a fourth through hole 43 corresponding to the second through hole 28 is provided on the back of the box cover 4 .
[0041] The partition 22 divides the interior of the box body 21 into a plurality of independent accommodating chambers. The vents 27 on the partition 22 form airflow channels between adjacent accommodating chambers to ensure uniform penetration of the disinfection steam. The first through hole 23 and the second through hole 28 are respectively provided on the front and back of the box body 21. The two groups of through holes are arranged in a staggered manner. When the box cover 4 is snapped onto the box body 21, the third through hole 44 on the front and the fourth through hole 43 on the back correspond to the first through hole 23 and the second through hole 28 of the box body 21 respectively. The rotational installation of the box cover 4 not only satisfies the entry of the disinfection steam during disinfection, but also prevents contaminants from entering the box during daily use. The fixing component 3 is composed of a base 32 and a snap-fit pin 31. The base 32 is inserted into the bottom of the box to realize both the fixing function and the anti-slip function through the protruding structure at the lower end. After the snap-fit pin 31 is inserted into the base 32, it fixes the beak 11 of the rubber dam clip 1 through the expansion effect to prevent the rubber dam clip 1 from shaking.
[0042] The entire storage box is made of high-temperature and high-pressure resistant materials to meet disinfection requirements. The transparent lid 4 facilitates easy identification of the rubber dam clip 1 model, significantly reducing the time it takes for medical staff to find the correct matching rubber dam clip 1, improving work efficiency, reducing patient wait time, and increasing patient satisfaction. The base 32 is made of a high-temperature resistant, flexible material, such as silicone rubber.
[0043] like Figure 3 As shown, the partitions 22 are divided into horizontal and vertical panels, with multiple horizontal and vertical panels arranged vertically and crosswise. The cross-arranged horizontal and vertical panels divide the interior of the box body 21 into multiple grid-shaped accommodating chambers. Based on the size of the rubber dam clip 1, a base 32 of corresponding specifications and sizes is installed in the grid accommodating chamber. This allows for flexible storage space division according to the different models and sizes of the rubber dam clips 1, allowing for appropriate placement of various types of rubber dam clips 1 (such as anterior tooth clips, premolar clips, and molar clips), improving the orderliness and rationality of storage. The grid-shaped structure also facilitates the circulation of disinfectant gas between the various accommodating chambers, enhancing disinfection efficiency. The height of the partitions 22 is slightly lower than the height of the outer frame of the box body 21, preferably enough to accommodate the rubber dam clips 1. This facilitates the removal and placement of the rubber dam clips 1, reduces the size, saves storage space, and facilitates ventilation during disinfection.
[0044] A typical grid matching scheme is as follows Figure 3 As shown, it is divided into three rows and four columns of grids, with a total of twelve small grids. The three rows of large grids correspond to three types of rubber dam clips 1: anterior tooth clips, premolar clips, and molar clips, and the rubber dam clips 1 are stored in categories.
[0045] A gap is defined between the bottom surface of the partition 22 and the top surface of the box bottom, connecting the bottoms of all the cavities. This gap serves a dual purpose: first, it allows wastewater to drain through the gap during cleaning, preventing dead corners where liquid could accumulate and facilitating the rinsing of dirt from each cavity; second, it creates a steam flow channel during disinfection, working in conjunction with the vents 27 to ensure uniform diffusion of high-temperature steam and eliminate dead corners.
[0046] like Figure 3 As shown, each first through hole 23 corresponds to an accommodating cavity, and each second through hole 28 corresponds to an accommodating cavity, wherein the second through holes 28 are evenly distributed and aligned with the vent holes 27 on the transverse plate, and the first through holes 23 and the vent holes 27 on the transverse plate are arranged in an alternating manner.
[0047] During disinfection, the box cover 4 is snapped into place with the through holes of the box body 21 one by one, so that high-temperature disinfection steam can enter the box body 21 for disinfection; after the disinfection is completed, the box cover 4 is opened and rotated 180 degrees, and then snapped into the box body 21. At this time, the through holes of the box body 21 and the box cover 4 are sealed to each other, which can prevent aerosols, dust, microorganisms, etc. in the clinic from entering the box during daily use.
[0048] like Figure 3 As shown, each of the accommodating chambers has a mounting hole 26 at the bottom. Figure 4 As shown, the base 32 has a snap ring 321 at the lower end, the upper side of the snap ring 321 has an upper edge 323, and the lower side of the snap ring 321 has a lower edge 324. The diameters of the upper edge 323 and the lower edge 324 are both larger than the diameter of the snap ring 321. Figure 6 As shown, the snap ring 321 is clamped on the mounting hole 26, the upper edge 323 is clamped on the upper end surface of the box bottom, and the lower edge 324 is clamped on the lower end surface of the box bottom.
[0049] The base 32 is fixed to the mounting hole 26 at the bottom of the box by a snap ring 321. The diameters of the upper edge 323 and the lower edge 324 are both larger than the diameter of the mounting hole 26. When assembling the base 32, first pass the upper end of the base 32 through the mounting hole 26 at the bottom of the box body 21, then pull it slightly, using the flexibility of the base 32 to allow the upper edge 323 to pass through the mounting hole 26 at the bottom of the box body 21. The snap ring 321 of the base 32 is positioned into the mounting hole 26, and the upper edge 323 and lower edge 324 of the base 32 are used to achieve bidirectional limit fixation of the base 32. This structure ensures that the base 32 will not fall off during sterilization and transportation, and the protruding lower edge 324 at the lower end can prevent the entire storage box from sliding, further preventing the rubber dam clip 1 from shaking. In addition, it allows for the removal and replacement of damaged individual bases 32, reducing maintenance costs.
[0050] The bases 32 of different specifications have the same structure and size of the lower edge 324, the clamping ring 321, and the upper edge 323, but the top shaft of the base 32 has different sizes. The diameters are divided into three sizes: large, medium, and small, so as to correspond to rubber dam clips 1 of different sizes.
[0051] like Figure 5 As shown, the base 32 is provided with a blind hole 325, into which the snap-fitting pin 31 is inserted, thereby expanding the outer wall of the base 32 outward. The diameter of the snap-fitting pin 31 is slightly larger than the diameter of the blind hole 325 of the base 32. The beak 11 of the rubber dam clamp 1 is inserted onto the shaft of the base 32, and then the snap-fitting pin 31 is inserted into the blind hole 325 of the base 32. The shaft of the base 32 is expanded and locked with the beak 11 of the rubber dam clamp 1, thereby securing the rubber dam clamp 1. This expansion and fixing mechanism allows for quick locking and release of the device without the need for special tools.
[0052] The base 32 is also provided with an air release hole 322, which is located at the bottom of the blind hole 325. The axis of the air release hole 322 is perpendicular to the axis of the blind hole 325, and the air release hole 322 is connected to the blind hole 325. During the insertion and removal of the fastening nail 31, the air release hole 322 can balance the air pressure inside the blind hole 325, making the insertion and removal of the fastening nail 31 easier. It also facilitates the entry of high-temperature steam to sterilize the interior of the blind hole 325 during sterilization.
[0053] like Figure 4 As shown, the top of the fastening pin 31 has a cap 311, which has a larger diameter than the top of the base 32. Once inserted, the cap 311 covers the top of the base 32, limiting vertical movement of the rubber dam clip 1 and preventing it from slipping due to vibration during transport. The cap 311 also serves as an operating handle, facilitating insertion and removal of the fastening pin 31.
[0054] like Figure 3 、 Figure 7 As shown, the tops of both sides of the box body 21 are provided with card slots 25, and both sides of the box cover 4 are provided with protrusions 42. The positions of the protrusions 42 of the box cover 4 correspond to the positions of the card slots 25 of the box body 21. The protrusions 42 are engaged in the card slots 25 to connect the box cover 4 and the box body 21 together.
[0055] The snap-fit design of the slots 25 on the top of the box body 21 and the protrusions 42 on both sides of the box cover 4 allows the box cover 4 to be securely fastened to the box body 21. The protrusions 42 snap into the slots 25, creating a simple and reliable connection that not only ensures that the box cover 4 will not fall off easily during normal use, but also allows medical staff to quickly open the box cover 4 when needed to perform operations such as taking the rubber dam clip 1 out or cleaning and disinfecting the storage box, thereby improving ease of use.
[0056] The bottom of both sides of the box body 21 are provided with protrusions 24, which protrude outward from the box body 21. The box cover 4 is provided with notches 41, and the positions of the notches 41 on the box cover 4 correspond to the positions of the protrusions 24 on the box body 21. When it is necessary to open the box cover 4, medical staff can easily apply force through the protrusions 24 and notches 41 to easily open the box cover 4, making it easier to operate inside the storage box and improving the user experience.
[0057] Although the above describes the specific embodiments of the present invention in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art on the basis of the technical solution of the present invention without creative work are still within the scope of protection of the present invention.
