technical field

The present invention relates to the technical field of medical devices, in particular to a freezing fat reduction device and a readable storage medium.

Background technique

Traditional non-invasive treatments for removing excess fat include topical medications, weight loss medications, regular exercise, dieting, or these treatments, which may be ineffective or even impossible in some cases. Furthermore, weight loss in selective areas of the body is often not achieved using a comprehensive or systematic approach to weight loss.

Further, the first cooling-conducting component 120 and the second cooling-conducting component 220 are connected by a flexible material (such as a ductile material such as silica gel). In the examples shown in FIGS. 5 to 8 , the cross-section of the second cooling member 220 is approximately an oval, and the cross-section of the second cooling member 220 is preferably smaller than that of the first cooling member 120 . , the distal end of the first lumen communicates with the proximal end of the second lumen.

The second refrigerating part 210 is similar to the first refrigerating part 110 , for example, it may include a semiconductor refrigeration block or a heat exchange head, so as to transfer the cooling energy to the skin through the second cooling-conducting part 220 . In the exemplary examples shown in FIGS. 5 to 8 , the second refrigeration component 210 includes two heat exchange heads disposed opposite to each other. For details, please refer to the description of the first refrigeration component 110 , which will not be repeated here.

Optionally, the temperature detection component is configured to acquire the preset temperature of the predetermined object based on the cooling of the first cooling component 110 . Preferably, the preset temperature can be obtained by acquiring the change of the skin surface temperature of the predetermined object. Optionally, the temperature detection component includes a first temperature detection unit, and the first temperature detection unit may include, for example, an external independent temperature sensor, or an additional device integrated in the second inner cavity and/or the first inner cavity. The temperature sensor can detect and acquire the surface temperature of the skin, especially the surface temperature of the part of the skin that is sucked into the second inner cavity or the first inner cavity and is in contact with the first cooling member 120 or the second cooling member 220 respectively. In some embodiments, the temperature detection component may include two temperature sensors for detecting the temperature of the skin surface drawn into the second lumen and the first lumen, respectively. In some other embodiments, the temperature detection component may include only one temperature sensor, and the temperature sensor is used to detect the temperature of the skin surface sucked into the second lumen and the first lumen respectively. Optionally, the temperature detection component further includes a second temperature detection unit, which can detect and obtain the temperature of the first cooling-conducting component 120 and the second cooling-conducting component 220 (ie, the temperature of the treatment surface). Here, the first cooling-conducting component 120 and the temperature of the second cooling-conducting part 220, respectively refer to the temperature of the end of the first cooling-conducting part 120 connected to the first refrigeration part 110, and the temperature of the end of the second cooling-conducting part 220 connected to the second refrigeration part 210, That is, the temperature of the first refrigeration part 110 and the second refrigeration part 210 . In some embodiments, different from the direct detection of the skin surface temperature by the first temperature detection unit, the skin surface temperature may be indirectly obtained by detecting the temperature of the treatment surface through the second temperature detection unit.

Optionally, the freezing and fat-reducing device further includes a negative pressure connecting unit 300, the negative pressure connecting unit 300 communicates with the first inner cavity, and is used for connecting negative pressure to the first inner cavity. In some embodiments, the negative pressure connection unit 300 may be, for example, a negative pressure connection hole provided on the proximal side of the second cooling member 220 , and the negative pressure connection hole can be connected to an external negative pressure end through a connecting pipe, so that it can be Negative pressure is provided in the first lumen to enable the skin to be drawn into the first lumen. For example, the negative pressure end can be an external vacuum pump, or a negative pressure pipeline provided centrally by the building.

The temperature detection component is configured to, based on the cooling of the first refrigeration component 110, acquire the change of the skin surface temperature of the predetermined object in the second inner cavity, and obtain the preset temperature of the predetermined object; the The second cooling component 210 is configured to cool according to a preset power curve, so as to maintain the skin surface temperature of the predetermined object at the preset temperature. The cooling of the first cooling component 110 can be regarded as a trial cooling detection of the skin surface. The inventors found that when the surface of the human skin is frozen and cooled, the release of the latent heat of the human body will cause a rebound in the temperature of the skin surface. The rebound point of this temperature is used as the preset temperature of cryotherapy, which has better safety and effectiveness, and will not freeze the skin. Different people have different release amounts of latent heat. Therefore, a preset temperature customized for human body differences can be obtained by the first cooling component 110 refrigerating to test the temperature of the skin surface. In other embodiments, the preset temperature may be set according to a predetermined safe temperature in addition to the rebound point of the skin surface temperature of the predetermined object. Specifically, the safe temperature is the temperature initially set by the freezing and fat-reducing device. In some cases, when latent heat is not detected, the rebound point of the skin temperature may not be obtained. In this case, the preset temperature can be set as a fixed temperature. Safe temperature to perform the next stage of cryotherapy. Further, after obtaining the preset temperature, the skin is frozen and cooled to the preset temperature by the second refrigeration component 210 for treatment. Optionally, the bounce point of the skin surface temperature can be obtained directly by the first temperature detection unit, or the bounce point of the skin surface temperature can be obtained indirectly by using the second temperature detection unit to detect the temperature of the treatment surface.

In this configuration, by using the first cooling component 110 to detect the temperature of the skin surface of the predetermined object, a customized preset temperature of the predetermined object can be obtained, and the second cooling component refrigerates according to the preset power curve, so that the said The temperature of the skin surface of the predetermined object is maintained at the preset temperature, which can ensure the effect of freezing, and can reduce the risk of frostbite to the skin during the freezing process. In addition, the second refrigerating component refrigerates according to the preset power curve, which can also shorten the treatment time.

Preferably, the freezing and fat-reducing device further comprises a heat insulating sheet (not shown), and the heat insulating sheet is detachably arranged in the second inner cavity or the first inner cavity; the heat insulating sheet It is configured to isolate the predetermined object from the second cooling member 220 during cooling by the first cooling member 110 to obtain the preset temperature. Further, the heat insulation sheet is further configured to remove the isolation between the predetermined object and the second cooling-conducting member 220 after the preset temperature is obtained by cooling by the first cooling member 110 . As described above, the method for using the freezing and fat-reducing device provided by this embodiment includes two stages. The first stage is a trial temperature drop detection of using the first refrigeration component 110 to cool to obtain a preset temperature, so as to obtain the preset temperature of the predetermined object. ; The second stage is to use the second cooling component 220 to perform cryotherapy on the predetermined object, so that the skin surface temperature of the predetermined object is maintained at a preset temperature. In the first stage, the heat insulation sheet is configured to isolate the second cooling-conducting component 220 from the skin. During the test temperature drop detection process in the first stage, the second cooling component 210 can also start cooling, so as to facilitate the cooling of the second cooling-conducting component 220 Pre-cooling is performed, and at this time, the skin and the second cooling conducting member 220 are isolated by the heat insulation sheet and will not be affected by the second cooling conducting member 220 . When the first stage is completed, the heat insulating sheet can be removed, and the pre-cooled second cooling-conducting component 220 can immediately start freezing and cooling the skin, which effectively shortens the treatment time. Optionally, the heat insulating sheet can be a sheet with a thermal conductivity less than 0.5, which can be sucked away by negative pressure to achieve removal from the second inner cavity or the first inner cavity. Specifically, by connecting the negative pressure to the first inner cavity through the negative pressure connection unit 300 , the heat insulating sheet can be removed from the negative pressure connection unit 300 and removed from the first inner cavity.

Optionally, the first refrigeration component 110 is configured to stop the refrigeration after the preset temperature is obtained by the first refrigeration component 110 for refrigeration. In the first stage, the first refrigerating part 110 is refrigerating, and the temperature detecting part obtains the rebound point of the skin temperature, or the first refrigerating part 110 stops refrigerating after the safety temperature is not obtained but the safety temperature is taken as the preset temperature. , wait for the skin to warm to room temperature.

In the following, with reference to FIG. 3 and FIG. 4 , two exemplary embodiments are used to illustrate the steps of using the freezing and fat-reducing device.

FIG. 3 shows a cooling curve of an exemplary embodiment. The steps of using the freezing and fat-reducing device are mainly divided into two stages. The first stage is a trial cooling detection of using the first cooling component 110 for cooling to obtain a preset temperature. , the second stage is to use the second cooling-conducting component 220 to perform cryotherapy on the predetermined object, so that the skin surface temperature of the predetermined object is maintained at a preset temperature. Curve A is the change of the skin surface temperature detected by the temperature detection component, wherein the curve A is only shown in the first stage, but not shown in the second stage; the curve B is the temperature change of the second cooling-conducting component 220 .

In the first stage S1, the first cooling component 110 starts cooling, and the first cooling component 120 is cooled to a predetermined temperature T (for example, -13° C.), the skin surface temperature decreases accordingly, and a rebound occurs when the latent heat is released, The temperature of the rebound point is recorded to provide a preset temperature Ts (ie, the reference target treatment temperature) for the next formal treatment, and then the first cooling component 110 is turned off for cooling to reverse the temperature of the skin surface to room temperature. It should be understood that, if the temperature of the rebound point cannot be obtained by the cooling of the first cooling component 110, the preset safe temperature is used as the preset temperature Ts. When the first cooling component 110 starts cooling, the second cooling component 210 also starts cooling, so that the second cooling component 220 is lowered to a standby temperature lower than the preset temperature Ts and maintained. At this time, due to the existence of the heat insulating sheet, the second cooling member 220 will not affect the skin surface. More specifically, in the first stage, the power curve of the second refrigeration component 210 includes a first power segment P1 and a second power segment P2 connected in sequence, and the second refrigeration component 210 is located under the first power segment P1. Refrigeration, so that the second cooling component 220 is pre-cooled to the standby temperature; the second cooling component 210 is cooled in the second power stage P2, so that the second cooling component is maintained at the standby temperature . It can be understood that the power of the second refrigeration component 210 in the first power section P1 is greater than the power of the second refrigeration component 210 in the second power section P2. Since the power of the first power stage P1 is relatively large, the temperature of the second cooling-conducting component 220 is fast, and the second cooling-conducting component 220 forms pre-cooling, which can effectively reduce the treatment time.

In the second stage S2, the power curve of the second refrigeration component 210 includes a third power segment P3, the third power segment P3 is connected to the second power segment P2, and the second refrigeration component 210 is in the third power segment P3. The power of the section P3 is greater than the power of the second refrigeration component 210 in the second power section P2. After the heat insulation sheet is removed and the cryotherapy is officially started, the second cooling component 210 increases the cooling power, and cools according to the power in the third power segment P3 to reduce the skin surface temperature of the predetermined object. In an alternative embodiment, the power of the second cooling component 210 in the third power section P3 is its maximum cooling power, so that after the cryotherapy is officially started, the temperature of the skin surface can drop rapidly, so as to reduce the treatment time .

Further, the power curve of the second cooling component 210 also includes a fourth power segment P4 and a fifth power segment P5. When the skin temperature is close to the preset temperature Ts, the second cooling component 210 reduces the cooling power, according to the fourth power segment. The power cooling of P4 makes the temperature of the skin surface gradually approach the preset temperature Ts. After the temperature of the skin surface reaches the preset temperature Ts, the second cooling component 210 increases the cooling power again, and cools according to the power of the fifth power section P5, so that the temperature of the skin surface is maintained at the preset temperature Ts. With this configuration, the entire cryotherapy process varies from person to person. While maximizing the curative effect, it reduces safety risks and reduces treatment time.

FIG. 4 shows a cooling curve of another exemplary embodiment. The difference from the exemplary embodiment shown in FIG. 3 is that in the first stage, when the first refrigeration part 110 starts refrigeration, the second refrigeration part 210 also Cooling is started, so that the second cooling-conducting component 220 is lowered to a standby temperature higher than the preset temperature Ts and maintained. Preferably, the standby temperature is less than 0°C.

In the second stage, the power curve of the second refrigeration component 210 includes the third power section P3 and the fifth power section P5, and may not include the fourth power section P4. Specifically, since the standby temperature is greater than the preset temperature Ts, after the heat insulation sheet is removed and the skin is sucked into the first inner cavity, the temperature of the second cooling member 220 will not cause frostbite on the skin surface, and only the second The cooling component 210 operates at the power of the third power section P3 to cool the skin surface until the temperature of the skin surface reaches the preset temperature Ts, and the second cooling component 210 operates at the power of the fifth power section P5, so that the temperature of the skin surface reaches the preset temperature Ts. maintained at the preset temperature Ts.
