Description

Technical Field

[0001] The present invention relates to the technical field of fat reduction devices, and in particular to a mechanical local fat reduction device. Background Art

[0002] Cryogenic fat reduction is a non-invasive way to eliminate fat. During the operation, the refrigeration system first cools the treatment head to a specified temperature, and then sucks the fat tissue at a specified position of the body into the treatment head, maintaining a freezing time of 30-60 minutes. Fat cells will wither in an environment of 2-5°C, and will then be excreted from the body by the metabolic system, thereby achieving the purpose of fat reduction. Moreover, skin cells have a strong ability to withstand low temperatures, so frostbite will not occur during the treatment process.

DETAILED DESCRIPTION

[0040] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] Combine the following Figures 1 to 5 The mechanical local fat reduction device of the present invention is described.

[0042] like Figures 1 to 5 As shown, the mechanical local fat reduction device provided by the embodiment of the present invention includes a treatment clamp 1, a negative pressure extraction device and a refrigeration system.

[0043] Specifically, the treatment clamp 1 includes a clamp body 2, and the clamp body 2 has a receiving chamber 3 and a negative pressure interface 20. The receiving chamber 3 is used to receive fat tissue, and the receiving chamber 3 is open to allow fat tissue to enter. The negative pressure interface 20 is connected to the receiving chamber 3, and the negative pressure interface 20 is connected to the negative pressure pumping device. The open end of the receiving chamber 3 is aligned and attached to the fat tissue at the target position, and the negative pressure pumping device is used to pump negative pressure into the receiving chamber 3 to suck the fat tissue into the receiving chamber 3, and the fat tissue will contact the side wall of the receiving chamber 3.

[0044] A medium flow channel 4 is provided on the side wall of the accommodating cavity 3, and the medium flow channel 4 can allow low-temperature medium to circulate inside the clamp body 2. A medium inlet 18 and a medium outlet 19 are provided on the clamp body 2, and both the medium inlet 18 and the medium outlet 19 are connected to the medium flow channel 4, and both the medium inlet 18 and the medium outlet 19 are connected to the refrigeration system to form a loop for the circulation of low-temperature medium.

[0045] The refrigeration system can perform cooling operations on low-temperature media. The clamp body 2 is made of a cooling material. The cooled low-temperature medium circulates in the medium flow channel 4, which can transfer the cold to the clamp body 2, reduce the temperature of the clamp body 2, and thus enable the low-temperature clamp body 2 to perform a low-temperature fat reduction operation.

[0046] With such arrangement, the present invention provides a low-temperature fat reduction device with a new refrigeration method, which utilizes a low-temperature medium instead of a semiconductor refrigeration plate to cool the clamp body 2, thereby solving the problem that the low-temperature fat reduction device in the prior art relies on a semiconductor refrigeration plate for refrigeration. Moreover, when multiple treatment clamps 1 are working at the same time, the refrigeration capacity of the refrigeration system for the low-temperature medium can be increased, thereby ensuring the refrigeration capacity requirements of each treatment clamp 1.

[0047] The target position may be the subject's neck, abdomen, inner thigh, jaw, etc., where fat needs to be reduced. The clamp body 2 for different positions may be set to different models and sizes.

[0048] In some embodiments, at least two treatment clamps 1 are provided, and the medium flow channel 4 of each treatment clamp 1 is connected to the same refrigeration system, and the negative pressure interface 20 of each treatment clamp 1 is connected to the same negative pressure extraction device, which has a compact structure, a high degree of modularization, is easy to maintain and adjust, and has a small size and good mobility. In this way, different treatment clamps 1 can be cooled at the same time by using the same refrigeration system, and negative pressure can be extracted from different treatment clamps 1 at the same time by using the same negative pressure extraction device. In other words, the mechanical local fat reduction device provided by the embodiment of the present invention can perform fat reduction operations on different positions at the same time, and the working efficiency is high.

[0049] When multiple treatment clamps 1 are connected to the same refrigeration system and negative pressure extraction device at the same time, a control valve needs to be provided at the medium inlet 18 and the negative pressure interface 20 of each treatment clamp 1, and each control valve is controlled separately. The control valve can be a stop valve, which can control the connection and disconnection of each treatment clamp 1 with the refrigeration system and the negative pressure extraction device respectively.

[0050] When a plurality of treatment clamps 1 are connected to the same refrigeration system and negative pressure extraction device at the same time, treatment clamps 1 of different models and sizes may be selected, or treatment clamps 1 of the same model and size may be selected.

[0051] The refrigeration system may be a vapor compression refrigeration system. The refrigeration capacity of the refrigeration system is large, and the refrigeration demand for multiple treatment clamps 1 can be met. Moreover, the refrigeration temperature of the refrigeration system is stable with little fluctuation.

[0052] In some embodiments, the refrigeration system has a refrigerant circuit, and the refrigerant in the refrigerant circuit flows directly into the medium flow channel 4 of the clamp body 2 , so that the refrigerant and the clamp body 2 directly exchange heat.

[0053] In other embodiments, the refrigeration system has a refrigerant circuit and a coolant circuit, so that the refrigerant of the refrigeration system cools the coolant, and then the coolant flows in the medium flow channel 4 of the clamp body 2. By using the coolant to cool the clamp body 2, the temperature of the clamp body 2 can reach -10 degrees Celsius to +5 degrees Celsius.

[0054] In a specific embodiment, the refrigeration system includes a refrigerant circuit and a power element 9 .

[0055] The refrigerant circuit includes a compressor 5, a condenser 6, a throttling element 7 and an evaporator 8. The evaporator 8 has a first passage and a second passage. The first passage is used for the circulation of the refrigerant, and the second passage is used for the circulation of the secondary coolant. The evaporator 8 can provide heat exchange between the refrigerant and the secondary coolant.

[0056] The exhaust end of the compressor 5, the condenser 6, the throttling element 7, the first passage and the suction end of the compressor 5 are connected in sequence to form a refrigerant circuit.

[0057] Specifically, the condenser 6 is a heat exchanger, and the condenser 6 has a third passage and a fourth passage. The two ends of the third passage are respectively connected to the exhaust end of the compressor 5 and the throttling element 7 for the circulation of refrigerant, and the fourth passage is used for the circulation of air, and heat exchange is performed between air and refrigerant to condense the refrigerant and release heat.

[0058] The compressor 5 runs, compresses the refrigerant, and then makes the refrigerant flow through the third passage of the condenser 6 , the throttling element 7 and the first passage of the evaporator 8 in sequence, and then flows back to the suction end of the compressor 5 .

[0059] The refrigerant is compressed by the compressor 5 to form high-temperature and high-pressure steam, which enters the condenser 6, where it releases heat and condenses to form high-pressure liquid. The high-pressure liquid passes through the throttling element 7 to form low-pressure and low-temperature refrigerant, which enters the evaporator 8, where it vaporizes and absorbs heat, thereby absorbing the heat of the refrigerant, completing the refrigeration and cooling of the refrigerant. After passing through the evaporator 8, the refrigerant forms low-temperature and low-pressure steam, which is then sucked into the suction end of the compressor 5, and the above steps are repeated.

[0060] The power element 9 has an inlet and an outlet. The outlet of the power element 9, the second passage, the medium flow channel 4 and the inlet of the power element 9 are connected to form a coolant circuit. The power element 9 is used to drive the coolant to circulate in the coolant circuit.

[0061] The coolant is cooled in the evaporator 8, and the cooled coolant enters the medium flow channel 4, performs heat exchange with the fixture body 2 in the medium flow channel 4, absorbs the heat of the fixture body 2, and completes the cooling operation of the fixture body 2. After absorbing the heat, the coolant continues to flow to the evaporator 8, and performs heat exchange with the refrigerant, and then the above steps are repeated.

[0062] The circulation of the refrigerant in the refrigerant circuit and the circulation of the brine in the brine circuit can ensure continuous cooling and temperature reduction of the brine.

[0063] The above-mentioned compressor 5 can be but is not limited to a small-displacement compressor 5 such as a piston type or a rotary type. The refrigerant can be at least one of 1,1,1,2-tetrafluoroethane (also known as HFC-134a, R134a, norflurane, with a chemical formula of C2H2F4), propane and isobutane. The above-mentioned coolant can be at least one of ethylene glycol, ethanol and water.

[0064] The evaporator 8 may be, but is not limited to, a shell and tube heat exchanger, a tube-and-fin heat exchanger, or a plate heat exchanger, and the throttling element 7 may be, but is not limited to, a capillary tube or a throttle valve.

[0065] In the embodiment of the present invention, the negative pressure extraction device includes a main pipeline, a first branch pipeline, a second branch pipeline and a vacuum pump 10 .

[0066] The first end of the main pipeline is connected to the negative pressure interface 20, the first branch pipeline and the second branch pipeline are arranged in parallel, the first end of the first branch pipeline and the first end of the second branch pipeline are both connected to the second end of the main pipeline, and the second end of the first branch pipeline and the second end of the second branch pipeline are both connected to the atmosphere.

[0067] The first branch pipeline and the second branch pipeline are both provided with stop valves, and the on-off of the first branch pipeline and the second branch pipeline is controlled by the stop valves. At this time, the stop valves on the first branch pipeline and the second branch pipeline can replace the control valve provided at the negative pressure interface 20 as described above.

[0068] The vacuum pump 10 is disposed in one of the first branch pipeline and the second branch pipeline.

[0069] Specifically, the vacuum pump 10 is arranged on the first branch pipeline. Before the fat reduction operation is performed and when the accommodating chamber 3 needs to be pumped under negative pressure, the stop valve on the second branch pipeline is controlled to be in the shutoff state, the stop valve on the first branch pipeline is controlled to be in the on state, and the vacuum pump 10 is controlled to operate, so that the accommodating chamber 3 can be pumped under negative pressure. When the fat reduction operation is completed and the treatment clamp 1 needs to be removed from the target position, the stop valve on the first branch pipeline is controlled to be in the shutoff state, and the stop valve on the second branch pipeline is controlled to be in the on state, so that the accommodating chamber 3 can be connected to the external atmosphere, so as to release the internal negative pressure of the accommodating chamber 3 and cancel the adsorption force of the clamp body 2 on the fat tissue, so that the treatment clamp 1 can be easily removed.

[0070] In the embodiment of the present invention, the negative pressure extraction device further includes a filter 11. The filter 11 is arranged on the main pipe and is used to filter the gas.

[0071] The main pipeline may not be provided, and the first end of the first branch pipeline and the first end of the second branch pipeline are both connected to the negative pressure interface 20, the vacuum pump 10 is provided on the first branch pipeline, and the stop valve and the filter 11 are provided on the first branch pipeline and the second branch pipeline.

[0072] In the embodiment of the present invention, the mechanical local fat reduction device further includes a first temperature detection element and a control device.

[0073] The first temperature detection element is disposed on the fixture body 2 and is used to detect the temperature of the fixture body 2 in real time.

[0074] The first temperature detection element, the refrigeration system and the negative pressure pumping device are all electrically connected to the control device, and the control device can control the start and stop of the refrigeration system and the negative pressure pumping device to realize the automatic control of the mechanical local fat reduction device. In addition, the control device can receive the temperature of the clamp body 2 detected by the first temperature detection element, and control the refrigeration capacity of the refrigeration system according to the measured value and target value of the temperature of the clamp body 2, so that the temperature of the clamp body 2 can be controlled within the target range.

[0075] The first temperature detection element can be, but is not limited to, a temperature sensor or a thermal resistor. The temperature of the fixture body 2 is detected by a thermal resistor, and the detection accuracy can reach 0.1 degrees Celsius.

[0076] In a further embodiment, the mechanical local fat reduction device further includes a display screen 17, which is disposed outside the clamp body 2. The display screen 17 is electrically connected to the control device, and the control device can control the display screen 17 to display the current temperature value and the target value of the clamp body 2, which is convenient for operation, so as to adapt to different fat reduction needs and improve fat reduction efficiency.

[0077] In some embodiments, the temperature sensor is disposed in the accommodating cavity 3 and in close contact with the skin of the target position to detect the temperature of the skin of the target position. The control device determines the temperature of the fat layer or muscle layer of the target position by one or more combinations of direct numerical calculation, CFD simulation calculation, deep learning calculation, etc., and visually displays the temperature distribution on the display screen 17, which helps the operator to adjust the fat reduction temperature in real time, achieve better fat reduction effect, and avoid frostbite.

[0078] In the embodiment of the present invention, the mechanical local fat reduction device further includes a second temperature detection element and a pressure detection element, and the first temperature detection element and the pressure detection element are both arranged in the refrigeration system for real-time detection of the parameters of the refrigerant. The first temperature detection element and the pressure detection element are both electrically connected to the control device, and the control device automatically controls the refrigeration capacity of the refrigeration system according to the parameters of the refrigerant and the target value of the temperature of the clamp body 2.

[0079] The second temperature detection element may be a temperature sensor, which may be provided at the exhaust end of the compressor 5, the outlet of the third passage of the condenser 6, the outlet of the first passage of the evaporator 8 and the outlet of the throttling element 7, respectively.

[0080] The pressure detection element may be a pressure sensor, and temperature sensors may be provided at the exhaust end of the compressor 5 and the intake end of the compressor 5 , respectively.

[0081] In some embodiments, the mechanical local fat reduction device further includes an input unit, which is electrically connected to the control device for the operator to set the target temperature value and duration. The operator can adjust the target temperature value and duration of the clamp body 2 in real time during the treatment process, or preset the target temperature value and duration of the temperature of the clamp body 2 in advance before the treatment begins, and the control device can control the refrigeration system according to the preset content.

[0082] In the embodiment of the present invention, the medium flow channel 4 extends along the circumference of the accommodating cavity 3, the medium inlet 18 and the medium outlet 19 are arranged adjacent to each other, and a partition plate is arranged inside the medium flow channel 4, and the medium inlet 18 and the medium outlet 19 are arranged on both sides of the partition plate. After the low-temperature medium enters the medium flow channel 4 from the medium inlet 18, it flows along the circumference of the accommodating cavity 3 and flows out from the medium outlet 19. The arrangement of the partition plate increases the orderliness of the low-temperature medium when it flows in the medium flow channel 4, and can improve the cooling performance of the low-temperature medium on the clamp body 2.

[0083] The medium flow channel 4 extends along the circumference of the accommodating cavity 3 and also extends along the height direction of the accommodating cavity 3, ensuring the volume of the medium flow channel 4, increasing the contact area between the low-temperature medium and the clamp body 2, and increasing the cooling performance of the low-temperature medium on the clamp body 2.

[0084] In some embodiments, the treatment clamp 1 further includes an antifreeze film, which extends along the wall of the accommodating cavity 3 and is in close contact with the wall of the accommodating cavity 3. When the treatment clamp 1 is used for fat reduction treatment, the antifreeze film is located between the clamp body 2 and the fat tissue at the target position, and the antifreeze film contacts the fat tissue at the target position instead of the clamp body 2, thereby preventing the skin at the target position from frostbite.

[0085] In the embodiment of the present invention, the treatment clamp 1 further includes a shell 12, which is made of a heat-insulating material and covers the outer wall of the clamp body 2. The shell 12 can reduce the loss of coldness of the clamp body 2 and avoid frostbite caused by direct contact between the operator and the clamp body 2.

[0086] Specifically, the material of the housing 12 may be, but is not limited to, plastic. The material of the clamp body 2 may be, but is not limited to, metal. The clamp body 2 may be obtained by using powdered metal through 3D printing technology or by welding molding technology.

[0087] The fixture body 2 and the housing 12 are detachably connected to facilitate inspection and maintenance.

[0088] In a specific embodiment, a mounting groove is provided on the housing 12, and the clamp body 2 is arranged in the mounting groove. A support seat is provided on the housing 12, and a support plate is provided on the outer side of the clamp body 2. When the clamp body 2 is placed inside the housing 12, the support plate can overlap the support seat, and the support plate and the support seat are detachably connected to realize the connection between the clamp body 2 and the housing 12.

[0089] Threaded holes can be provided on the support seat and the support plate, and the support seat and the support plate can be connected by bolts. A plurality of threaded holes are provided, and the plurality of threaded holes are distributed at intervals along the circumference of the open end of the accommodating cavity 3, and the clamp body 2 and the housing 12 are connected together by a plurality of bolts, so that the stability of the connection structure between the clamp body 2 and the housing 12 can be improved.

[0090] In some embodiments, the open end of the accommodating cavity 3 protrudes from the shell 12 in a direction away from the bottom wall of the accommodating cavity 3, that is, the open end of the accommodating cavity 3 forms a convex edge 13. When the open end of the clamp body 2 is aligned with the fat tissue at the target position, the convex edge 13 contacts the fat tissue at the target position, and the contact area is relatively small. This can ensure the fit between the fat tissue at the target position and the open end of the clamp body 2, ensure the smooth progress of the negative pressure pumping operation, and ensure that the fat tissue is not easy to fall off after the negative pressure pumping operation is completed.

[0091] The housing 12 has a handle, and the main pipeline, the pipeline at the medium inlet 18, and the pipeline connected to the medium outlet 19 all extend along the axis of the handle. The negative pressure device and the refrigeration system are both arranged in the machine body, and the three pipelines are located between the handle and the machine body to form a pipeline bundle, which is neat and easy to manage.

[0092] To facilitate the arrangement of the above three pipelines in the housing 12, the housing 12 can be set as a split structure. The housing 12 includes a first shell 14 and a second shell 15. The cross-section of the first shell 14 and the second shell 15 is parallel to the plane where the opening of the accommodating cavity 3 is located, and the cross-section passes through the central axis of the handle part. The first shell 14 and the second shell 15 are detachably connected together by bolts.

[0093] To ensure the structural stability of the housing 12 , a protective ring 16 may be provided at the end of the handle portion of the housing 12 . The protective ring 16 is sleeved outside the ends of the handle portions of the first shell 14 and the second shell 15 .

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
