Description
Technical Field
[0001] The present invention relates to the technical field of medical devices, and in particular to a detachable graphene constant temperature defogging mouth mirror. Background Art
[0002] The mouth mirror is one of the most common medical instruments used in dental treatment. Its main function is to reflect and focus light, and to pull or push the lips, cheeks, and tongue. In actual operation, due to the large temperature difference between the mouth mirror and the oral environment, as well as the debris and water vapor generated when operating a high-speed turbine handpiece, the mirror surface fogs up or condenses water droplets, which in turn affects the physician's operating field of view and causes inconvenience to dental treatment. The current anti-fogging solutions actually used in clinical practice are not ideal: the mirror surface treated by the hot air blower baking method cools down too quickly, and the iodine wiping method affects the exploration field of view and has an odor. In addition, disposable plastic mouth mirrors are currently mostly used, which also has the disadvantages of wasting resources and increasing costs.
[0003] Therefore, the present invention proposes a detachable graphene constant temperature defogging mouth mirror, which adopts a graphene water-based heating film and a phase change heat storage material mixed with sodium acetate trihydrate, water and gelatin to achieve electric heating and anti-fogging of the mouth mirror.
[0004] Graphene water-based heating ink is a conductive ink composed of graphene as a conductive filler, modified acrylic resin as a connector and a variety of additives. Compared with traditional metal wires, it has the advantages of high electrothermal conversion rate, high conductivity, low resistivity, corrosion resistance, low cost and small size. It can be printed or sprayed on a thin film and used in small heating devices.
[0005] Phase-change thermal storage utilizes the latent heat of phase change in specific phase-change materials to store and utilize thermal energy. This technology offers the advantages of high energy storage density and the ability to absorb and release heat at a constant temperature. This allows for controlled temperature increases, ultimately stabilizing the temperature within a constant range. This prevents burns and effectively alleviates lens fogging. Phase-change thermal storage also prolongs the duration of the temperature increase, saving energy.
[0006] In terms of appearance, the overall hexagonal prism shape of the handle is designed for pen-like grip, which is in line with the clinical usage habits of doctors; the longitudinal anti-slip grooves on the surface of the rotary switch not only increase the friction when holding, but also make it easier for doctors to distinguish the knob switch through intuitive tactile feeling, thereby eliminating the trouble of doctors having to move their eyes to confirm the switch status when performing oral exploration on patients; in addition, the detachable three-section design facilitates the repair of faults in various components, and the replaceable lens is also easy to recycle and reuse after disinfection, reducing the waste of disposable materials. Summary of the Invention
[0007] In view of the above analysis, the present invention aims to provide a detachable graphene constant temperature defogging mouthpiece to solve the problem of unsatisfactory clinical defogging solutions raised in the above background technology.
[0008] A detachable graphene constant temperature defogging mouth mirror comprises a detection unit, a control unit, and an energy supply unit. The detection unit is connected to the control unit via a lead socket 6; the control unit and the energy supply unit are connected via a female connector 15. The entire device can be placed upright using a placement platform at the rear end of the energy supply unit.
[0009] In the aforementioned detection unit, a waterproof layer 2 is placed below the glass lens 1 and above the lens base of the mirror holder 5. A phase-change heat storage material 3 is filled in the interlayer between the waterproof layer 2 and the lens base. A graphene circuit board 4 is arranged in this interlayer. The mirror holder 5 has a hollow stem welded to the rear of the lens base. A wire 10 is arranged inside the stem. The lead plug at the rear end of the stem is connected to the lead socket 6 of the control unit.
[0010] In the control unit, a lead socket 6 secures the mouth mirror frame 5 of the detection unit. The rear end of the lead socket 6 features a connecting slot and a thin rod, which secures the spring pawl 8. The internal structure of the one-way rotary switch 7 consists of a twelve-tooth ratchet with six ratchet lead pieces 9 spaced at intervals on each of its twelve corners. Rotation of the one-way rotary switch 7 causes the front end of the ratchet lead piece 9 to contact and conduct electricity with the spring pawl 8. The rear end of the ratchet lead piece 9 is welded to a thin copper ring 11, which is then slidably connected to a thick copper ring 12. The thick copper ring 12 is backed by an insulating filler 13. The front end of the handle connector 14 features a cylindrical connecting rod with a slot on one side, housing a wire 10. The aforementioned components—insulating filler 13, thick copper ring 12, thin copper ring 11, and one-way rotary switch 7—are sequentially mounted on this cylindrical connecting rod. The connecting rod at the front end of the handle connector 14 is riveted to the connecting slot at the rear end of the lead socket 6. The rear end of the handle connector 14 is connected to the power supply unit.
[0011] In the energy supply part, the hexagonal hollow battery box 17 is used to place the lithium battery 16. The lithium battery 16 and the battery box 17 are fixed to the handle connecting piece 14 through the connector socket 15 and the rotating mortise structure respectively.
[0012] The technical solution of the present invention has at least one of the following beneficial effects:
[0013] First, the present invention realizes temperature-controlled heating and anti-fogging of the mouth mirror, which improves the fogging phenomenon of the lens. The phase-change constant temperature material interlayer prolongs the temperature duration, limits the temperature rise, avoids the risk of scalding the patient, and thus ensures the safety of the inspection operation.
[0014] Secondly, the present invention enables the doctor to operate the switch at any angle when holding the mouth mirror in a pen-like manner. The design of the rotary switch enhances the convenience of operation.
[0015] Third, the present invention enables visual distinction between the heating and power-off states. By distinguishing between the on and off states based on the alignment of the hexagonal switch and the handle, the physician can avoid the need to shift their gaze mid-examination to confirm the switch status. This simplifies operation and makes heating safer.
[0016] Fourthly, the present invention realizes one person one mirror. By using interchangeable lenses, cross contamination between patients is avoided, thus ensuring medical safety.
[0017] Fifthly, the present invention achieves a reusable effect. The rechargeable handle and the sterilizable and recyclable lens design make the mouth mirror device more environmentally friendly.
[0018] Sixth, the present invention achieves the effect of convenient maintenance. The detachable three-section design avoids the problem of being difficult to repair and having to be discarded due to the integrated molding, facilitates after-sales service, and extends the service life.

[0035] A specific embodiment of the present invention discloses a detachable graphene constant-temperature defogging mouth mirror, comprising three parts: a detection unit, a control unit, and a power supply unit. The detection unit includes a glass lens 1, a waterproof layer 2, a phase-change heat storage material 3, a graphene circuit board 4, and a mouth mirror frame 5; the control unit includes a lead socket 6, a one-way rotary switch 7, a spring pawl 8, a ratchet lead piece 9, a wire 10, a thin copper ring 11, a thick copper ring 12, an insulating filler block 13, and a handle connector 14; and the power supply unit includes a connector socket 15, a lithium battery 16, and a battery compartment 17. When using the heated constant-temperature defogging mouth mirror of the present invention, the one-way rotary switch 7 of the control unit is toggled to control the circuit. When in continuous heating mode, the glass lens 1 of the detection unit is maintained at a constant temperature suitable for the oral environment, keeping the mirror surface clear and fog-free, facilitating operations such as oral exploration. After heating is complete, the one-way rotary switch 7 is toggled again in the same direction to disconnect the circuit, thereby achieving a temperature-controllable heated mouth mirror device that improves the fogging phenomenon of the lens. After use, the device can be disassembled into three sections, respectively for disinfecting and recycling the detection part and charging the energy supply part.
[0036] The following describes the specific structure and installation method of the detection unit:
[0037] The detection part includes: a glass lens 1, a waterproof layer 2, a phase-change heat storage material 3, a graphene circuit board 4, and a mouth mirror frame 5.
[0038] The waterproof layer 2 is placed below the glass lens 1 and above the lens base of the mirror holder 5. A phase-change heat storage material 3 is placed in the interlayer between the waterproof layer 2 and the lens base. A graphene circuit board 4 is placed in this interlayer. The mirror holder 5 has a hollow stem welded to the rear of the lens base. A wire 10 is placed inside the stem. A lead plug at the rear end of the stem connects to a lead socket 6 on the control unit.
[0039] Furthermore, a waterproof layer 2 is fixed between the glass lens 1 and the lens base of the oral mirror frame 5. A phase-change heat storage material 3, a mixture of sodium acetate trihydrate, water, and gelatin, is filled in the interlayer between the waterproof layer 2 and the lens base. This material is used to maintain a constant temperature in the oral mirror lens of the detection unit, achieving both safe heating and defogging.
[0040] Furthermore, the graphene circuit board 4 is arranged in the above-mentioned interlayer, and is surrounded by a phase-change heat storage material 3 for achieving temperature-controllable heating.
[0041] Furthermore, the front end of the mouth mirror rod of the mouth mirror frame 5 is welded to the rear of the lens base, and the rear end of the mouth mirror rod is connected to a lead plug, which is connected to the lead socket 6 of the detection part, so as to achieve the purpose of detachable mouth mirror lens, which is convenient for disinfection, recycling and reuse of the mouth mirror lens.
[0042] Furthermore, the mirror rod of the mirror frame 5 is a hollow structure with a wire 10 arranged inside. The front end of the wire 10 is connected to the graphene circuit board 4 for connecting the circuit and transmitting the energy of the power supply part to the detection part. The graphene circuit board 4 of the detection part converts the electrical energy into thermal energy to achieve the purpose of heating and demisting.
[0043] The following describes the specific structure and installation method of the control unit:
[0044] The control part includes: a lead socket 6, a one-way rotary switch 7, a spring pawl 8, a ratchet lead piece 9, a wire 10, a thin copper ring 11, a thick copper ring 12, an insulating filling block 13, and a handle connecting piece 14.
[0045] The lead socket 6 secures the mouth mirror frame 5 of the detection unit. The rear end of the lead socket 6 has a connecting slot and a thin rod that secures the spring pawl 8. The internal structure of the one-way rotary switch 7 consists of a twelve-tooth ratchet with six ratchet lead pieces 9 spaced at intervals on each of the twelve corners. Rotation of the one-way rotary switch 7 causes the front end of the ratchet lead piece 9 to contact the spring pawl 8, creating electrical conductivity. The rear end of the ratchet lead piece 9 is welded to a thin copper ring 11, which is then slidably connected to a thick copper ring 12. The thick copper ring 12 is backed by an insulating filler 13. The front end of the handle connector 14 has a cylindrical connecting rod with a slot on one side and a wire 10 arranged inside. The aforementioned components—insulating filler 13, thick copper ring 12, thin copper ring 11, and one-way rotary switch 7—are sequentially mounted on this cylindrical connecting rod. The connecting rod at the front end of the handle connector 14 is riveted to the connecting slot at the rear end of the lead socket 6. The rear end of the handle connector 14 is connected to the power supply unit.
[0046] Furthermore, the overall appearance of the control part is a hexagonal prism, which is convenient for doctors to hold it like a pen.
[0047] Furthermore, the front end of the lead socket 6 has a cross-shaped groove for fixing the lead plug of the mirror frame 5; the rear end of the lead socket 6 has a connecting groove that rivets the cylindrical connecting rod at the front end of the handle connecting piece 14. The rear end of the lead socket 6 also has a thin rod for fixing the spring pawl 8.
[0048] Furthermore, the surface of the one-way rotary switch 7 has longitudinal anti-slip grooves to increase the friction when holding; the internal structure is a twelve-tooth ratchet, and six ratchet guide pieces 9 are arranged at intervals on the twelve corners of the ratchet. The circuit switch is controlled by toggling the one-way rotary switch 7 of the control part to achieve temperature control at any time during the heating process.
[0049] Furthermore, the front end of the handle connector 14 has a connecting rod with a slot on one side that rivets into the connecting slot at the rear end of the lead socket 6. The two slots are aligned, and a wire 10 is arranged within them. The wire 10 runs through the slot and is then welded to one side of a spring pawl 8. The spring pawl 8 is a metal conductive member that, through the rotation of the one-way rotary switch 7, contacts the six ratchet lead pieces 9. The ratchet lead pieces 9 are welded to thin copper rings 11, which are then slidably connected to thick copper rings 12. The thick copper rings 12 are backed by insulating filler blocks 13. A wire is connected to the thick copper rings 12 and enters the slot of the connecting rod at the front end of the handle connector 14, ultimately completing the circuit connection of the device.
[0050] Furthermore, the aforementioned components: insulating filler block 13, thick copper ring 12, thin copper ring 11, and one-way rotary switch 7, are sequentially mounted on the connecting rod at the front end of handle connector 14. The rear end of handle connector 14 has a groove with an XH2.54-type interface at its bottom. The groove wall has a latching structure for a rotating, snap-on connection with the energy supply unit.
[0051] The following introduces the specific structure and installation method of the energy supply unit:
[0052] The energy supply unit includes: a female connector 15 , a lithium battery 16 , and a battery box 17 .
[0053] The hexagonal hollow battery box 17 is used to accommodate the lithium battery 16. The lithium battery 16 and the battery box 17 are fixed to the handle connecting piece 14 through the connector socket 15 and the rotating mortise structure respectively.
[0054] Furthermore, the overall appearance of the energy supply part is a hexagonal prism, which is connected to the handle connecting piece 14 of the control part. The outer surface of the front end of the hollow battery box 17 has a protrusion for rotating and locking the handle connecting piece 14.
[0055] Furthermore, there is a cylindrical groove inside the battery box 17 for placing the rechargeable lithium battery 16, the model of which is R-14500-1. The conductive connector of the lithium battery 16 is fixed to the handle connecting piece 14 through the connector socket 15, and the model of the connector socket 15 is XH2.54.
[0056] When the constant temperature heating defogging mouth mirror of the present invention is implemented:
[0057] Step 1: Hold the mirror in a pen-like position, and pinch the lead socket 6 of the control part with your thumb and index finger.
[0058] Step 2: Keep the index finger in its original position and hold the fixing device together with the long finger. Bend the thumb and turn the one-way rotary switch 7 toward the side to a rotation angle of 30 degrees. The device circuit is connected, and the energy supply unit continuously outputs energy, which is transmitted to the detection unit through the wire 10. The graphene circuit board 4 of the detection unit converts the electrical energy into heat energy to heat the glass lens 1.
[0059] Step 3: In the heating state, the temperature of the glass lens 1 continues to rise. The phase-change heat storage material 3 can be used to keep the temperature of the glass lens 1 constant within a certain range, thereby keeping the mirror surface clear and fog-free, facilitating operations such as oral exploration.
[0060] Step 4: After heating is completed, hold the fixture with the index finger and long finger together, bend the thumb, and turn the one-way rotary switch 7 in the same direction again to a rotation angle of 30 degrees to disconnect the circuit and stop heating.
[0061] Step 5: After use, the device can be disassembled into three parts: detection part, control part, and energy supply part. The detection part can be recycled and reused after disinfection, and the energy supply part can be charged for continued use next time.
