Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to a dental nib sterilization and transfer device. Background Technology
[0002] Dental burs are consumables used by dentists. They are very small steel needles, usually consisting of a needle tip and a shank. They can be inserted into a handheld drill to help dentists open cavities and repair teeth. If we compare a dentist's handheld drill to a mobile phone, then the dental bur is like the drill bit on the drill. The cleaning and disinfection of dental burs is very important because it is related to protecting the health of doctors and patients and preventing cross-infection.
[0003] Currently, during the cleaning of burs, collisions with other objects can cause the burs to be shaken out of the storage box. Additionally, the buoyancy of water can easily cause the burs to detach from the storage box, resulting in loss. Existing devices address this issue by adding a clamping component inside the storage box, but this presents the following problems in actual operation:
[0004] 1. Cleaning fluid is usually corrosive. The clamping components in the storage box are prone to aging and corrosion under the action of cleaning fluid. When the clamping components are corroded and aged, they can no longer clamp the needle, thus losing their fixation and causing the needle to be easily lost repeatedly.
[0005] 2. The existing device mainly uses the friction between the box and the U-shaped guide groove on the storage box to fix the box and the storage box. However, after long-term use, the friction between the U-shaped guide groove and the box will decrease, and the box will easily loosen. Utility Model Content
[0006] To address the aforementioned issues, the present invention aims to provide a sterilization and transport device for dental nibs, which uses negative pressure for fixation, thereby solving the problem of easy corrosion and aging of existing clamping components.
[0007] To achieve the above objectives, the present invention adopts the following technical solution:
[0008] A sterilization and transport device for dental burs includes an open box, a bur storage assembly disposed within the open box, and a cover movably disposed above the open box to cover its opening. The bur storage assembly includes a sealed box fixed within the open box, a bur insert plate with a detachable sealing cover on the top of the sealed box, an inflation / deflation port located on one side of the bottom of the sealed box with one end connected to the interior of the sealed box and the other end connected to the outside, and a sealing plug placed on the inflation / deflation port. The bur insert plate is provided with a plurality of needle holes spaced apart along the thickness direction to accommodate burs, and each needle hole is fixedly fitted with an elastic sealing ring that can interfere with the outer peripheral wall of the bur.
[0009] More preferably, the top of the needle insert plate is provided with several sets of guide components that are adapted to each needle hole and are used to guide the needle; each set of guide components includes a pair of elastic members symmetrically fixed on both sides of the needle hole on the upper surface of the needle insert plate and whose movable ends abut against each other; a wear-resistant layer is provided on the side of the opposite side of the two elastic members.
[0010] More preferably, the lower part of the sealed box is surrounded by a limiting protrusion, and a mesh plate with a mesh size smaller than the needle diameter is placed above the limiting protrusion.
[0011] More preferably, a pair of symmetrically arranged rotating components are provided between the open box body and the lid body, and the open box body and the lid body are rotatably connected by the rotating components; each set of rotating components includes a U-shaped guide groove embedded in one side of the upper surface of the open box body along the width direction of the open box body and a rotating rod rotatably disposed at one end inside the U-shaped guide groove along the width direction of the U-shaped guide groove; the lid body is inverted U-shaped, and the two side walls of the open end of the lid body are respectively fixedly connected to the rotating rods in the two sets of rotating components.
[0012] More preferably, an adsorption assembly is provided between the cover and the U-shaped guide channel; the cover and the U-shaped guide channel are fixed by the adsorption assembly; the adsorption assembly includes a first magnetic suction member embedded in the end of the U-shaped guide channel away from the rotating rod and a second magnetic suction member embedded in the corresponding position at the bottom of the cover and cooperating with the first magnetic suction member to achieve fixation.
[0013] More preferably, a handle is fixed to the top of the cover.
[0014] More preferably, the bottom of the needle insert plate is provided with an annular groove that is adapted to the sealing box body, and a sealing strip is provided between the annular groove and the sealing box body, and the needle insert plate is sealed on the sealing box body by the sealing strip.
[0015] This utility model has the following beneficial effects:
[0016] 1. In this invention, after multiple sets of needles are inserted into the corresponding elastic sealing rings, a sealed space is formed between the sealing box and the needle insert plate. After removing the sealing plug from the inflation / deflation port, the air extraction mechanism (such as an air pump or suction machine) is connected to the inflation / deflation port to extract the air from the sealed space between the sealing box and the needle insert plate. The sealing plug is then inserted back into the inflation / deflation port, thereby making the air pressure in the sealed space lower than the external air pressure. This causes the lower part of the needle to be fixed in place by the needle insert plate and the sealing box under negative pressure, minimizing the risk of the needle falling out of the storage box due to collisions with other objects or buoyancy, thus reducing needle loss. Furthermore, since the needle is fixed by negative pressure, it will not be corroded by cleaning fluid or age, thereby extending the service life of the device.
[0017] 2. This utility model strengthens the fixation between the lid and the open box by attracting the first magnetic component and the second magnetic component, thus avoiding the lid from opening naturally as much as possible. At the same time, due to the magnetic effect, it can reduce the possibility of the lid loosening and easily separating from the open box after long-term use. Attached Figure Description

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0025] A sterilization and transport device for dental burs includes an open box 1, a bur storage assembly 2 disposed within the open box 1, and a cover 3 movably disposed above the open box 1 to cover the opening of the open box 1. The bur storage assembly 2 includes a sealed box 21 fixed within the open box 1, a bur insert plate 22 with a detachable sealing cover on the top of the sealed box 21, an inflation / deflation port 23 disposed on one side of the bottom of the sealed box 21 with one end communicating with the interior of the sealed box 21 and the other end communicating with the outside, and a plug inserted into the inflation / deflation port 23. The sealing plug 24 on the 3; the needle insert plate 22 is provided with a plurality of needle holes 221 arranged along the thickness direction and capable of accommodating needles, and each needle hole 221 is fixedly fitted with an elastic sealing ring 25 that can be interference-fitted with the outer peripheral wall of the needle; the bottom of the needle insert plate 22 is provided with an annular groove 222 adapted to the sealing box 21, and a sealing strip 223 is provided between the annular groove 222 and the sealing box 21, and the needle insert plate 22 is sealed and covered on the sealing box 21 by the sealing strip 223.
[0026] After multiple sets of needles are inserted into the corresponding elastic sealing rings 25, a sealed space is formed between the sealing box 21 and the needle insert plate 22. After removing the sealing plug 24 from the inflation / deflation port 23, the air extraction mechanism, such as an air pump or suction machine, is connected to the inflation / deflation port 23 to extract the air from the sealed space formed between the sealing box 21 and the needle insert plate 22. The sealing plug 24 is then inserted back into the inflation / deflation port 23, thereby making the air pressure in the sealed space lower than the external air pressure. This causes the lower part of the needle to be fixed in the needle insert plate 22 and the sealing box 21 under the action of negative pressure, minimizing the risk of the needle falling out of the storage box due to collisions with other objects or buoyancy, thus reducing needle loss. At the same time, since the needle is fixed by negative pressure, it will not be corroded by the cleaning fluid or age, thereby extending the service life of the device.
[0027] As a possible implementation of this solution, preferably, the top of the needle insert plate 22 is further provided with several sets of guide components 26 that are adapted to each needle hole 221 and used to guide the needle; each set of guide components 26 includes a pair of elastic members 261 symmetrically fixed on both sides of the needle hole 221 on the upper surface of the needle insert plate 22 and whose movable ends abut against each other; a wear-resistant layer 262 is provided on the opposite side of the two elastic members 261; the arrangement of the two elastic members 261 plays a guiding role when the needle passes into the elastic sealing ring 25, and also clamps the needle at the same time, further reducing the situation of the needle separating from the needle insert plate 22.
[0028] As a possible implementation of this solution, preferably, the lower part of the sealed box 21 is provided with a limiting protrusion 27, and a mesh plate 28 is placed above the limiting protrusion 27, which is parallel to the needle insert plate 22 and has a mesh size smaller than the needle diameter. The mesh plate 28 can prevent the needle from directly contacting the bottom of the sealed box 21. On the one hand, when the space formed between the sealed box 21 and the needle insert plate 22 is consistent with the external air pressure, when there is residual disinfectant on the needle, it can fall into the sealed box 21 for collection, thereby minimizing the risk of rust and corrosion caused by long-term contact between disinfectant and the needle. On the other hand, it also reduces the friction and scratching between the needle and the bottom of the sealed box 21 caused by vibration when cleaning the needle, thereby improving the service life of the device.
[0029] As a possible implementation of this solution, preferably, a pair of symmetrically arranged rotating components 4 are provided between the open box body 1 and the cover body 3 on both sides of the open box body 1, and the open box body 1 and the cover body 3 are rotatably connected by the rotating components 4; each set of rotating components 4 includes a U-shaped guide groove 41 embedded in one side of the upper surface of the open box body 1 along the width direction of the open box body 1 and a rotating rod 42 rotatably disposed at one end inside the U-shaped guide groove 41 along the width direction of the U-shaped guide groove 41; the cover body 3 is inverted U-shaped, and the two side walls of the open end of the cover body 3 are fixedly connected to the rotating rods 42 in the two sets of rotating components 4 respectively; through the cooperation of the U-shaped guide groove 41, the rotating rod 42 and the cover body 3, the cover body 3 is always connected to the open box body 1, thereby reducing the possibility of the cover body 3 being easily lost due to separation from the open box body 1.
[0030] As a possible implementation of this solution, preferably, an adsorption component 5 is also provided between the cover 3 and the U-shaped guide groove 41; the cover 3 and the U-shaped guide groove 41 are fixed by the adsorption component 5; the adsorption component 5 includes a first magnetic suction member 51 embedded in the end of the U-shaped guide groove 41 away from the rotating rod 42 and a second magnetic suction member 52 embedded in the corresponding position at the bottom of the cover 3 and cooperating with the first magnetic suction member 51 to achieve fixation; through the attraction of the first magnetic suction member 51 and the second magnetic suction member 52, the fixation between the cover 3 and the open box 1 is strengthened, and the natural opening of the cover 3 is avoided as much as possible. At the same time, due to the magnetic effect, the situation where the cover 3 becomes loose and easily separates from the open box 1 after long-term use can be reduced.
[0031] As a possible implementation of this solution, preferably, a handle 31 is fixedly provided on the top of the cover 3 to facilitate opening the cover 3.
[0032] The working principle of this device is as follows:
[0033] First, pull the handle 31 to separate the first magnetic component 51 and the second magnetic component 52, and continue to apply force to open the cover 3 by rotating the rod 42.
[0034] The second step is to pass the lower part of several needles through the corresponding guide components 26 and sealing strip 223 in sequence, and then continue to move downwards until they abut against the mesh plate 28;
[0035] The third step is to remove the sealing plug 24 from the inflation / deflation port 23, and then connect it to the inflation / deflation port 23 through a suction mechanism such as a suction machine or air pump. Then, the air between the sealing box 21 and the needle insert plate 22 is extracted. Next, the sealing plug 24 is inserted back into the inflation / deflation port 23. Since the external air pressure is greater than the air pressure in the space formed between the sealing box 21 and the needle insert plate 22, multiple needles will be firmly attracted into the sealing box 21.
[0036] Fourth step, press the cover 3 towards the open box 1 so that the two sides of the cover 3 are respectively located in the two U-shaped guide grooves 41 and the first magnetic suction member 51 attracts the corresponding second magnetic suction member 52. At this time, the installation of the needle is completed.
[0037] Fifth step: After the needle is cleaned, open the cover 3, and then remove the sealing plug 24 from the inflation / deflation port 23. Air enters the space between the sealing box 21 and the needle insert plate 22 from the inflation / deflation port 23, so that the internal and external air pressure are consistent. At this time, the needle can be pulled out from the top.
[0038] The above description is only a specific embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural transformations made based on the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
