As shown in fig. 1 and 2, an embodiment of the present invention provides a frozen fat reduction device, which includes: a first cooling part 110, a first cold-conducting part 120, a second cooling part 210, a second cold-conducting part 220, and a temperature detecting part (not shown). The first cooling part 110 is in heat conduction connection with the first cold guiding part 120, the second cooling part 210 is in heat conduction connection with the second cold guiding part 220, and the first cold guiding part 120 is arranged at the far end side of the second cold guiding part 220; the second cold guiding member 220 has a first inner cavity for accommodating a predetermined subject, and the temperature detecting member is for detecting the skin surface temperature of the predetermined subject.
Fig. 5 to 8 show an exemplary embodiment of a frozen fat reduction device, which will be described below with a predetermined portion of a human body as a predetermined object. The cryo-lipid-lowering device has an axis perpendicular to the skin (perpendicular to the plane of the paper in fig. 5), and optionally, the first cold conducting member 120 has a second lumen in communication with the first lumen for receiving the predetermined subject. The axial height of the first cold guiding member 120 is smaller, so that the second inner cavity forms a flat shape. In the example shown in fig. 5 to 8, the first cooling element 120 has a generally oblong cross-section with an open distal end for placement on the skin such that the skin can be drawn into the second lumen from the open distal end. In other embodiments, the first cold-conducting part 120 can also be a plate, which directly abuts the skin without the second lumen. Optionally, the first cooling component 110 is attached to the distal end side of the first cold guiding component 120 and is in heat conduction connection with the first cold guiding component 120, for example, the first cooling component 110 is attached to the first cold guiding component 120 by heat conduction silicone grease, so as to achieve heat conduction connection. The first cooling member 110 may include, for example, a semiconductor cooling block or a heat exchange head, which enables cooling and transfers cooling to the skin through the first cold conduction member 120. In the example shown in fig. 5 to 8, the first cooling part 110 includes two heat exchange heads each having a coolant flow inlet and a coolant flow outlet, and the coolant can flow in the heat exchange heads to remove heat, thereby cooling. The specific structure of the heat exchange head, the type, flow rate and flow velocity of the cooling liquid, etc. can be reasonably set by those skilled in the art according to the prior art, and will not be further described herein. Of course, in other embodiments, the first cooling member 110 may also include a semiconductor cooling block.
The second cooling guide member 220 is disposed adjacent to the proximal side of the first cooling guide member 120, and the axial height of the second cooling guide member 220 is greater than the axial height of the first cooling guide member 120, so that the first lumen is formed in a cylindrical shape. Further, the first cold guiding member 120 and the second cold guiding member 220 are connected by a flexible material (e.g., a malleable material such as silicone). In the example shown in fig. 5 to 8, the second cooling guide member 220 has a generally oblong cross-section, and the second cooling guide member 220 preferably has a cross-section smaller than that of the first cooling guide member 120, and the distal end of the first lumen communicates with the proximal end of the second lumen. More preferably, the first cold guiding member 120 is coaxially arranged with the second cold guiding member 220. In practice, after being sucked into the second lumen, the skin can be further sucked into the first lumen from the junction of the first lumen and the second lumen. If the first cold conducting member 120 is a plate member, it has an inner hole through which skin is sucked into the first inner chamber. It should be noted that the shape of the first cold guiding member 120 and the second cold guiding member 220 in the present embodiment is not limited in particular, the oval cross-section in the above exemplary embodiment is only an example and should not be considered as a limitation to the shape of the first cold guiding member 120 and the second cold guiding member 220, and those skilled in the art can select other shapes such as oval, round, or rectangular with rounded corners according to the prior art.
Optionally, the second cooling component 210 is attached to a sidewall of the second cooling conducting component 220 in a radial direction or attached to a proximal side of the second cooling conducting component 220 in an axial direction, and is in heat-conducting connection with the second cooling conducting component 220. The second cooling member 210, like the first cooling member 110, may include a semiconductor cooling block or a heat exchange head, for example, to transfer cooling energy to the skin through the second cooling directing member 220. In the exemplary embodiment shown in fig. 5 to 8, the second cooling unit 210 includes two heat exchanging heads disposed opposite to each other, and please refer to the description of the first cooling unit 110, which is not repeated herein.
Optionally, the temperature detecting component is configured to obtain a 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 variation of the skin surface temperature of the predetermined object. Optionally, the temperature detecting component includes a first temperature detecting unit, and the first temperature detecting unit may include an external independent temperature sensor, or an additional temperature sensor integrally disposed in the second inner cavity and/or the first inner cavity, and is capable of detecting and acquiring a surface temperature of the skin, particularly a surface temperature of a portion of the skin that is sucked into the second inner cavity or the first inner cavity and is in contact with the first cold guiding component 120 or the second cold guiding component 220, respectively. In some embodiments, the temperature sensing component may include two temperature sensors for sensing the temperature of the skin surface drawn into the second lumen and the first lumen, respectively. In other embodiments, the temperature detection component may include only one temperature sensor, and the temperature sensor may be used to detect the skin surface temperature drawn into the second lumen and the first lumen, respectively. Optionally, the temperature detecting component further includes a second temperature detecting unit, which is capable of detecting and acquiring the temperatures of the first cold guiding component 120 and the second cold guiding component 220 (i.e. the temperature of the treatment surface), where the temperatures of the first cold guiding component 120 and the second cold guiding component 220 refer to the temperature of the end of the first cold guiding component 120 connected to the first cooling component 110 and the temperature of the end of the second cold guiding component 220 connected to the second cooling component 120, i.e. the temperatures of the first cooling component 110 and the second cooling component 120, respectively. In some embodiments, the skin surface temperature may be indirectly obtained by detecting the temperature of the treatment surface through the second temperature detection unit, unlike the first temperature detection unit which directly detects the skin surface temperature. Similarly, the second temperature detection unit may also include one or two temperature sensors, and the specific arrangement position and the temperature measurement form thereof are not limited.
Optionally, the freezing fat reduction device further includes a negative pressure connection unit 300, and the negative pressure connection unit 300 is communicated with the first inner cavity and is used for accessing a 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 disposed at the proximal side of the second cold guiding member 220, and the negative pressure connection hole may be connected with the external negative pressure end through a connection pipe, so that the negative pressure may be provided in the first lumen, and the skin may be sucked into the first lumen. The negative pressure end can be an external vacuum pump or a negative pressure pipeline which is centrally provided by a building.
The temperature detection component is configured to acquire the change condition of the skin surface temperature of the predetermined object in the second inner cavity based on the refrigeration of the first refrigeration component 110, so as to obtain the preset temperature of the predetermined object; the second cooling component 210 is configured to cool according to a preset power curve to maintain the skin surface temperature of the predetermined subject at the preset temperature. The cooling of the first cooling component 110 can be regarded as a test cooling of the skin surface. The inventor finds that when the skin surface of a human body is cooled by freezing, the release of latent heat of the human body can cause the temperature on the skin surface to rebound. The rebound point of the temperature is used as the preset temperature of the freezing treatment, so that the safety and the effectiveness are better, and the skin can not be frostbitten. Different people have different latent heat release amounts, so that the preset temperature customized for the human body difference can be obtained through the trial cooling detection of the first cooling part 110 on the skin surface. In other embodiments, the preset temperature may be set according to a predetermined safe temperature in addition to the debounce point of the skin surface temperature of the predetermined subject. Specifically, the safe temperature is the temperature initially set by the freezing fat-reducing device, and in some cases, when latent heat is not detected, the bounce point of the skin temperature may not be obtained, and at this time, the preset temperature may be set to be the fixed safe temperature, so as to perform the next stage of the freezing treatment. Further, after the preset temperature is obtained, the skin is cooled to the preset temperature by the second refrigerating part 210 for treatment. Alternatively, the first temperature detection unit can be used for directly detecting to obtain the debounce point of the skin surface temperature, and the second temperature detection unit can be used for indirectly detecting the temperature of the treatment surface to obtain the debounce point of the skin surface temperature.
With this configuration, a customized preset temperature of a predetermined subject can be obtained by a trial cooling detection of the skin surface temperature of the predetermined subject using the first cooling part 110, and the second cooling part cools according to a preset power curve so that the skin surface temperature of the predetermined subject is maintained at the preset temperature, so that the freezing effect can be secured and the risk of frostbite of the skin during the freezing process can be reduced. In addition, the second refrigerating part refrigerates according to a preset power curve, and the treatment time can be shortened.
Preferably, the frozen fat reduction device further comprises a heat insulation sheet (not shown), wherein the heat insulation sheet is detachably arranged in the second inner cavity or the first inner cavity; the heat insulating sheet is configured to insulate the predetermined object from the second cold guiding part 220 in the process of being cooled by the first cooling part 110 to obtain the preset temperature. Further, the heat insulating sheet is configured to remove the insulation of the predetermined object from the second cold guiding member 220 after the preset temperature is obtained by the first cooling member 110. As described above, the using method of the freezing fat-reducing device provided by the embodiment includes two stages, the first stage is a test cooling detection that the first cooling part 110 is used for cooling to obtain a preset temperature, so as to obtain the preset temperature of the predetermined object; the second stage is to perform a cryotherapy on the predetermined subject using the second cold guiding member 220 to maintain the skin surface temperature of the predetermined subject at the preset temperature. The thermal insulation sheet is configured to isolate the second cold guiding component 220 from the skin in the first stage, and during the test cooling detection in the first stage, the second cooling component 210 may also start cooling so as to pre-cool the second cold guiding component 220, while the skin is isolated from the second cold guiding component 220 by the thermal insulation sheet and is not affected by the second cold guiding component 220. After the first stage is completed, the heat insulation sheet can be removed, and the pre-cooled second cold guide component 220 can immediately start to perform freezing and cooling on the skin, so that the treatment time is effectively shortened. Optionally, the heat insulation sheet may be a sheet with a thermal conductivity less than 0.5, and may be removed from the second cavity or the first cavity by being sucked by the negative pressure. Specifically, negative pressure is introduced into the first inner cavity through the negative pressure connection unit 300, so that the heat insulation sheet can be removed from the first inner cavity through the negative pressure connection unit 300.
Optionally, the first refrigeration component 110 is configured to stop refrigeration of the first refrigeration component 110 after the preset temperature is obtained by refrigeration of the first refrigeration component 110. In the first stage, the first refrigeration component 110 refrigerates, and after the temperature detection component acquires the bounce point of the skin temperature or the safety temperature is used as the preset temperature when the bounce point is not acquired, the first refrigeration component 110 stops refrigerating and waits for the skin to be heated to the room temperature.
The steps of using the cryo-lipid reduction device are described below in connection with fig. 3 and 4 by two exemplary embodiments.
Fig. 3 shows a cooling curve of an exemplary embodiment, the using step of the freezing and fat-reducing device is mainly divided into two stages, the first stage is a test cooling test using the first cooling component 110 to cool to obtain a preset temperature, and the second stage is a freezing treatment of the predetermined subject using the second cooling-leading component 220 to maintain the skin surface temperature of the predetermined subject at the preset temperature. A curve a is a change in the skin surface temperature detected by the temperature detecting means, wherein the curve a is shown only in the first stage and is not shown in the second stage; curve B shows the temperature variation of the second cold guiding member 220.
In the first stage S1, the first cooling component 110 starts cooling, so that the first cooling conducting component 120 is cooled to a certain predetermined temperature T (for example, -13 ℃), the skin surface temperature is lowered, a rebound occurs when latent heat is released, the temperature of the rebound point is recorded, a preset temperature Ts (i.e. a reference target treatment temperature) is provided for the next formal treatment, and then the first cooling component 110 is turned off to cool, so that the skin surface is reversely heated to room temperature. It should be understood that if the temperature of the anti-trip point cannot be obtained by the refrigeration of the first refrigeration component 110, the preset safe temperature is taken as the preset temperature Ts. At the same time when the first cooling part 110 starts cooling, the second cooling part 210 also starts cooling, so that the second cold guiding part 220 is cooled to a standby temperature less than the preset temperature Ts and maintained. At this time, the second cold guiding member 220 does not affect the skin surface due to the existence of the heat insulating sheet. More specifically, in the first phase, the power curve of the second cooling unit 210 includes a first power segment P1 and a second power segment P2 connected in sequence, and the second cooling unit 210 cools in the first power segment P1, so that the second cold guiding unit 220 precools and reduces to the standby temperature; the second cooling part 210 cools at the second power segment P2, so that the second cold guiding part is maintained at the standby temperature. It is understood that the power of the second cooling element 210 in the first power stage P1 is greater than the power of the second cooling element 210 in the second power stage P2. Because the power of the first power segment P1 is relatively large, the temperature of the second cold-conducting component 220 is quickly reduced, and the second cold-conducting component 220 is precooled, so that the treatment time can be effectively reduced.
In the second stage S2, the power curve of the second cooling unit 210 includes a third power segment P3, the third power segment P3 is connected to the second power segment P2, and the power of the second cooling unit 210 in the third power segment P3 is greater than the power of the second cooling unit 210 in the second power segment P2. After the heat insulating sheet is removed and the freeze treatment is started, the second cooling unit 210 increases the cooling power and cools at the power of the third power stage P3 to lower the skin surface temperature of the predetermined subject. In an alternative embodiment, the power of the second cooling part 210 in the third power segment P3 is the maximum cooling power, so that the skin surface temperature can be rapidly decreased after the actual start of the freezing treatment, in order to reduce the treatment time.
Further, the power curve of the second cooling unit 210 further includes a fourth power segment P4 and a fifth power segment P5, when the skin temperature approaches the preset temperature Ts, the second cooling unit 210 reduces the cooling power, and cools according to the power of the fourth power segment P4, so that the temperature of the skin surface gradually approaches 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 segment P5, so that the temperature of the skin surface is maintained at the preset temperature Ts. With the configuration, the whole freezing treatment process is different from person to person, so that the safety risk is reduced and the treatment time is shortened while the maximum curative effect is obtained.
Fig. 4 shows a cooling curve of another exemplary embodiment, which is different from the exemplary embodiment shown in fig. 3 in that in the first stage, at the same time when the first cooling component 110 starts cooling, the second cooling component 210 also starts cooling, so that the second cold-conducting component 220 is cooled to a standby temperature higher than the preset temperature Ts and maintained. Preferably, the standby temperature is less than 0 ℃.
In the second stage, the power curve of the second cooling part 210 includes the third power stage P3 and the fifth power stage P5, and may not include the fourth power stage P4. Specifically, since the standby temperature is higher 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 cold guide component 220 does not cause damage such as frostbite on the skin surface, and only the second cold guide component 210 needs to operate according to the power of the third power segment P3 to cool the skin surface until the temperature of the skin surface reaches the preset temperature Ts, and then the second cold guide component 210 operates according to the power of the fifth power segment P5 to maintain the temperature of the skin surface at the preset temperature Ts. The temperature of the second cold guiding member 220 of this example is always higher than the preset temperature Ts, so that the damage such as frostbite to the skin is avoided. To further reduce the treatment time, it may be considered to set the standby temperature to a value close to the preset temperature Ts.
