Description

Technical Field

[0001] The present invention relates to a dental cold compress technology, and in particular to a dental cold compress device and a use method thereof. Background Art

[0002] During dental extraction, especially extraction of molars, also known as "wisdom teeth", patients are generally required to apply cold compresses to the affected area after the operation to reduce swelling of their maxillofacial area. Currently, the most common method is for the doctor to ask or for the patient to prepare an ice pack themselves, and then hold the ice pack in hand and apply it to the corresponding position after the operation. However, this method has the following defects: 1. The ice pack needs to be held continuously, and other things cannot be continued; 2. Holding the ice pack will cause discomfort and difficulty in the hand, and it cannot last long; 3. If the ice pack is not used properly (such as without a pad, etc.), it will not only cause greater irritation to the patient's maxillofacial skin at the extraction site, but also cause frostbite to the skin because the patient cannot control the time and degree of ice application.

[0003] In addition, some cold compresses are available on the market. They are easy to use and can be applied directly to the skin of the maxillofacial area where the tooth was extracted. Although these patches can free up your hands, they lack a clear temperature range and are difficult to control to achieve a sustained effect. Most importantly, the temperature is not low enough, often exceeding zero degrees Celsius, providing only a cooling sensation and falling far short of the clinical requirement for effectively reducing swelling. Summary of the Invention

[0004] In order to solve the above problems in the prior art, the present invention provides a dental cold compress device and a method of use, which can apply ice to the affected maxillofacial area after tooth extraction and can free both hands.

The fixing plate and the upper end of the silicon capsule body are provided with heat dissipation ports. The lower end of the radiator passes through the upper end of the silicon capsule body and the fixing plate in sequence through the heat dissipation ports and is connected to the upper surface of the semiconductor refrigeration piece. The bottom surface of the silicon capsule body is provided with an adhesive layer, and the bottom surface of the silicon capsule body also has an opening. The temperature probe is arranged at the opening and sealed with the silicon capsule body. The temperature control circuit board is arranged on the fixing plate and is electrically connected to the host, semiconductor refrigeration piece, temperature probe and radiator respectively.

[0006] The cold compress mechanism has a pair, which is arranged on both sides of the main machine through two fixing plates. The inner ends of the two fixing plates are respectively connected to the two ends of the casing through hinges.

[0007] The cold compress mechanism is single, and its single silicon capsule body is fixed to the lower part of the main unit through a fixing plate, and the side of the silicon capsule body is also provided with a groove adapted to the nose for breathing.

[0008] The cold compress device also includes a pressurizing device, including an air pump arranged in the casing, an air bag molded in the silicon capsule body and located between the water bag and the fixed plate, and a pressure-sensitive patch attached to the surface of the adhesive layer. The air bag is provided with a corresponding heat dissipation port for the radiator to pass through. The air pump extends into the silicon capsule body through an air pipe and is connected to the air bag. The pressure-sensitive patch and the air pump are respectively electrically connected to the temperature control circuit board.

[0009] Buckles are respectively provided at the outer ends of the two silicon capsule bodies and are connected via an elastic fixing belt.

[0010] The fixing plate is made of ABS material.

[0011] The adhesive layer adopts nano aerogel.

[0012] In another aspect, a method for using a dental cold compress device comprises the following steps:

[0013] A. Before use, turn on the pre-cooling of the cold compress device and control the semiconductor refrigeration chip to cool the liquid in the silicon capsule into ice;

[0014] B. Apply the frozen silicone capsule to the affected area of the patient's jaw and face through the adhesive layer on the bottom for ice compress. Set the cold compress temperature range, lower limit temperature, cold compress time, safe temperature range, and cycle time.

[0015] C. Use the temperature probe to measure the temperature of the affected skin surface in real time. When the measured temperature reaches the set cold compress temperature range, the semiconductor refrigeration chip stops cooling and the cold compress timer is set;

[0016] D. When the measured temperature is lower than the set lower limit of the cold compress temperature or the set cold compress time is reached, the semiconductor refrigeration chip is controlled to increase the temperature so that the skin returns to the set safe temperature range for rest;

[0021] The dental cold compress device and method of use of the present invention have the following advantages:

[0022] 1. The water in the silicon capsule is iced by the semiconductor refrigeration sheet, and the adhesive layer on the silicon capsule can be applied to the affected area without hands, providing effective ice compress. It not only has a good effect in stopping bleeding and reducing swelling, but also frees up hands. Because surgical operations will cause certain damage to tissues, ice compress can shrink small blood vessels, achieve the effect of postoperative hemostasis, and promote the absorption of interstitial fluid and reduce interstitial fluid exudation, thereby achieving the purpose of reducing swelling. At the same time, the silicon capsule also acts as a cushion, which can reduce direct irritation to the skin to a certain extent.

[0023] 2. It has a temperature probe that can accurately control the ice compress. The semiconductor refrigeration chip can be used to increase or decrease the temperature of the liquid in two directions according to the measured temperature, so that the affected skin can reach the temperature required for the cold compress and can also be set to rest in a cycle, thus avoiding long-term low temperature frostbite;

[0024] 3. It also has an air bag, which is located under the fixing plate. The air pump can inflate and pressurize the affected area to enhance the hemostatic effect. At the same time, precise pressurization can be achieved through pressure measurement.

[0025] 4. It has a radiator, which can ensure the cooling effect of the semiconductor refrigeration sheet and is also conducive to rapid ice making;

[0026] 5. Two types of silicone capsules are designed according to different affected areas: a pair type can meet the needs of ice compresses in various parts of the maxillofacial area, and through a hinged and rotatable fixing plate, the two silicone capsules can be adjusted to the maxillofacial area and fit the maxillofacial area better, especially for ice compresses after the extraction of lower molars. The two silicone capsules can form a certain angle so that the lower silicone capsule can be attached to the lower part of the mandible; the independent type uses one silicone capsule, which can be attached between the upper lip and the nose to apply ice to the affected area after the extraction of the incisors, and by setting corresponding grooves, it can adapt to nasal breathing.

[0039] The following further describes a dental cold compress device and a method of use of the present invention.

[0040] Example 1

[0041] like Figures 1-9As shown, the dental cold compress device of the present invention specifically comprises a main unit 1 and a cold compress mechanism 2 connected to the main unit 1. The main unit 1 includes a housing 3, a touchscreen LCD screen 4 mounted on the surface of the housing 3, and a rechargeable battery 5 located within the housing 3. Reference numeral 26 in the figure denotes the rechargeable battery port. The cold compress mechanism 2 comprises a pair of cold compress mechanisms 2, one located on either side of the main unit 1. Each cold compress mechanism 2 comprises a fixing plate 6, a silicon capsule 7, a semiconductor cooling plate 8, a heat sink 9, a temperature probe 10, and a temperature control circuit board 11. The fixing plate 6 can be made of ABS material, for example. Its inner end is connected to the housing 3 via a hinge 12. The silicon capsule 7 is secured to the fixing plate 6 by secondary injection molding. A water bladder 13 is located within the lower portion of the silicon capsule 7. The water bladder 13 contains water and has an open top. The semiconductor cooling plate 8 (e.g., a Peltier thermoelectric semiconductor cooling device) is located below the fixing plate 6, with its lower end extending into the water bladder 13 to contact the water, cooling it to ice or heating it to a higher temperature. The openings between the semiconductor cooling sheet 8 and the water bladder 13 can be sealed using, for example, UV glue. The fixing plate 6 and the upper end of the silicon capsule body 7 are provided with a heat dissipation vent 14 that communicates vertically. The lower end of the radiator 9 passes through the upper end of the silicon capsule body 7 and the fixing plate 6 in sequence through the heat dissipation vent 14, and is then bonded to the upper surface of the semiconductor cooling sheet 8 using, for example, 4011 quick-drying glue. The bottom surface of the silicon capsule body 7 is provided with an adhesive layer 15, such as nano-aerogel, for attachment to the affected skin of the maxillofacial area. The bottom surface of the silicon capsule body 7 also has an opening. The temperature probe 10 can be arranged along the fixing plate 6 and then penetrated into the water bladder 13. It is located at the opening, with only the tip exposed and flush with the bottom surface of the silicon capsule body 7. This ensures both contact with the skin for detecting skin temperature and a comfortable fit. The temperature probe 10 fits tightly with the opening of the silicon capsule body 7 and is also sealed with glue. The temperature control circuit board 11 is arranged on the fixed plate 6 and has a dust cover 16. It is also electrically connected to the host 1, the semiconductor refrigeration plate 8, the temperature measuring probe 10, and the radiator 9 respectively. The control parameters can be input through the touch LCD screen 4, and the temperature control circuit board 11 can be used to control the semiconductor refrigeration plate 8 to cool or heat up, and control the real-time temperature measurement of the temperature measuring probe 10. In addition to ordinary physical heat dissipation, the radiator 9 can also be loaded with voltage to achieve rapid heat dissipation when making ice.

[0042] The pair of silicon capsules 7 of this embodiment can meet the cold compress requirements of most areas of the mandibular face, especially after extraction of lower teeth such as lower molars. Because the fixing plate 6 is hinged to the main unit 1, the two silicon capsules 7 can rotate to form an angle, allowing ice compresses to be applied to the upper and lower parts of the mandible. For the upper molars, vertical or horizontal flat application can be used accordingly. The outer ends of the two silicon capsules 7 are respectively provided with buckles 17 and connected by an elastic fixing band 18. By putting the elastic fixing band 18 on the head, it can achieve a double insurance effect with the nano aerogel.

[0043] In addition, the current method of stopping bleeding after tooth extraction is usually to insert a cotton ball into the dental site and ask the patient to bite it tightly for 30 minutes to apply pressure to stop bleeding. However, due to the anesthetic and swelling after tooth extraction, many patients cannot bite the cotton ball properly into the dental site. At the same time, because the patient cannot swallow the saliva secreted during the biting of the cotton ball, it can also cause bleeding in the wound. Therefore, the cold compress device of this embodiment also includes a pressurizing device, specifically including a micro air pump 19 (such as a DC diaphragm negative pressure pump DC3V, etc.) provided in the housing 3, an air bag 21 formed in the silicon capsule body 7 and located between the water bag 13 and the fixing plate 6, and a pressure-sensitive patch 22 attached to the surface of the adhesive layer 15. The air bag 21 can be integrally injection-molded with the water bag 13. The airbag 21 is provided with a corresponding heat dissipation port 14 in the middle for the radiator 9 to pass through (i.e., the airbag 21 is in a U-shaped configuration at this position). The entire airbag 21 is a sealed structure, and the air pump 19 extends into the silicon capsule body 7 and communicates with the airbag 21 via a three-way air supply pipe 20. The airbag 21 is sealed with UV glue, etc. (25 in the figure represents the air pump air inlet pipe). The pressure-sensitive patch 22 and the air pump 19 are respectively electrically connected to the temperature-controlled circuit board 11. The airbag 21 can be inflated by the air pump 19 according to the pressure parameters set by the touch screen 4. Since the upper portion of the airbag 21 is a fixed plate 6, the inflated airbag 21 mainly generates pressure downward, which acts on the water bag 13 to pressurize the affected area until the surgical site, thereby achieving a rapid hemostasis effect (the principle of compression hemostasis is to use external pressure to shrink and physically close the rupture of the blood vessel, reduce local blood flow, promote blood coagulation and platelet aggregation, and achieve the purpose of hemostasis). Accurate pressure application can be achieved by measuring the pressure through the pressure-sensitive patch 22. This pressure application measure can be used together with ice packs or alone as needed.

[0044] The above-mentioned touch LCD screen 4, semiconductor cooling plate 8, radiator 9, temperature probe 10, temperature control circuit board 11, air pump 19 and other components as well as the connection and control therebetween can all adopt existing technologies and will not be repeated here.

[0045] Example 2

[0046] like Figure 10-12 As shown, the main difference between the dental cold compress device of this embodiment and embodiment 1 is that only one silicon capsule body 7 is used. The silicon capsule body 7 adopts a shape that matches the position of the front teeth and the positions on both sides (i.e., a long rectangular body), and there is also a groove 23 on the side of the silicon capsule body 7 that adapts to the nose for breathing. And its fixing plate 6 is directly connected to the lower part of the main unit 1, so that the main unit 1 is located in the middle position of the entire silicon capsule body 7, and the temperature control circuit board 11 is located on the fixing plate 6 and placed in the main unit 1. The rest of the structure is similar to that of embodiment 1 and will not be repeated here. The dental cold compress device of this embodiment is specially used for cold compressing the affected area after the extraction of the front teeth to reduce swelling and apply pressure to stop bleeding.

[0047] The dental cold compress device of the present invention is used in the following specific manner:

[0048] A. Before use, turn on the pre-cooling of the cold compress device and control the semiconductor refrigeration sheet 8 to cool the liquid in the silicon capsule 7 into ice;

[0049] B. The frozen silicon capsule 7 is attached to the affected area of the patient's maxillofacial area via the adhesive layer 15 on the bottom surface for ice compress. The doctor can set the corresponding cold compress temperature range, cold compress lower limit temperature, cold compress time, safe temperature range, and cycle time through the host 1 based on the patient's condition and clinical experience;

[0050] C. The temperature of the affected skin surface is measured in real time by the temperature measuring probe 10. When the measured temperature reaches the set cold compress temperature range, the semiconductor refrigeration sheet 8 is stopped from continuing to cool and the cold compress timer is set;

[0051] D. When the measured temperature is lower than the set lower limit of the cold compress temperature or reaches the set cold compress time, the semiconductor refrigeration chip 8 is controlled to increase the temperature so that the skin returns to the set safe temperature range for rest;

[0052] E. When the rest period reaches the cycle time, the semiconductor refrigeration sheet 8 is used for cooling to apply ice again;

[0053] F. Repeat steps CE.

[0054] In step B, if pressurized hemostasis is required, the doctor sets the pressure and starts the air pump 19 to inflate the airbag 21. The airbag 21 causes the silicon capsule body 7 to pressurize the affected area. At the same time, the pressure of the affected area is measured through the pressure-sensitive patch 22. When the set pressure is reached, the inflation is stopped and the pressure is maintained for a certain period of time, such as 30 minutes, to achieve rapid hemostasis.

[0055] In steps AF, the corresponding set temperature, set cold compress time, measured temperature, cold compress time, and remaining power are displayed on the LCD screen.

[0056] However, those skilled in the art should recognize that the above embodiments are merely intended to illustrate the present invention and are not intended to limit the present invention. As long as they are within the spirit of the present invention, any changes or modifications to the above embodiments will fall within the scope of the claims of the present invention.
