`Description
`
`FIELD OF THE INVENTION
`
`[0001] The present invention relates to a fat-reduction
`method for removing body fat and a weight-loss appara-
`tus using the same.
`
`BACKGROUND OF THE INVENTION
`
`[0002] Chinese invention patent No. 2007800142034
`and No. 2007800000090 respectively discloses a cools—
`culpting device designed to effect a fat reduction. All of
`these devices take a merit from such a basic principle
`that the triglyceride in adipose will solidifies at 5°C. Thus,
`by sending cooling wave onto the site in need of fat-re-
`duction through a non-invasive therapeutic device, the
`triglyceride can be solidified through freezing. Because
`solidification of the triglyceride can result in it’s prema-
`turely aging, which cause the triglyceride be mildly
`cleansed and excreted through normal metabolism, the
`fat layer can be reduced and thereby a local fat reduction
`is effected. However, such a fat reduction method has
`some drawbacks which are mainly as follows: on one
`hand, the heavy—degree frostbite ofskin epidermal tissue
`will occur if the skin is under an environment of 5°C for
`
`a long time; on the other hand, because majority of the
`fat in the blood vessel is in fusion with the blood and even
`
`much of fat are surroundingly attached to the blood ves-
`sels, the blood vessels are prone to be simultaneously
`frozen to solidify during freezing of the fat, which will se-
`riously damage the human body.
`[0003]
`To overcome one of the above drawbacks of
`easily producing the frostbite of epidermal tissue in the
`current coolsculpting fat reduction technique, Chinese
`invention
`patent
`No.200780000012.2
`and
`No.200780001010.5 respectively discloses an antifreez—
`ing agent configured to be applied in coolsculpting fat
`reduction. The usage of such antifreezing agent can re-
`duce effectively the frostbite of skin epidermal tissue.
`However, it still can not solve the problem of simultane-
`ous solidification of the blood vessels and the fat.
`
`SUMMARY OF THE INVENTION
`
`[0004] An object of the invention is to provide a fat-
`reduction weight-loss method capable of avoiding frost-
`bite of tissues, such as vascular tissue and skin tissue.
`[0005] A further object of the invention is to provide a
`weight loss apparatus applying said fat-reduction weight-
`loss method.
`
`[0006] According to one aspect of the invention, it pro-
`vides a fat-reduction weight-loss method, comprising:
`firstly, locally heating a site in need offat—reduction under
`37 °C to 60 °C until the blood and muscles separate with
`the fat; then, locally freezing the site in need of fat-reduc-
`tion under -10°C to 5 °C until the fat solidifies.
`
`[0007] According to the fat-reduction weight-loss
`
`method of the invention, the local heating to the site in
`need of fat—reduction could accelerate blood circulation
`at the site in need of fat-reduction and induce the blood
`
`and the muscles to separate with thefat. Then, the instant
`freezing to the site in need of fat-reduction could induce
`solidification ofthe fat so as to avoid injure oftissue death
`damage caused by the simultaneous solidification of the
`blood and the muscles during the coolsculpting of the fat.
`The solidified fat will prematurely age and be absorbed
`or excreted through human metabolism. A microscope
`can be used for observing the separation of the blood
`and the muscles with the fat as well as solidification of
`the fat.
`
`In some embodiments, after locally heating a
`[0008]
`the site in need of fat-reduction under 37 °C to 60 °C, a
`pause may be taken for about 1 minute followed by locally
`freezing the site in need of fat-reduction under -10°C to
`5 °C . The pause results in slightly decreasing epidermal
`temperature of human body and performing buffer func-
`tion for the follow-up instant freezing.
`[0009]
`In some embodiments, a step of applying anti-
`freezing agent or laying an antifreezing film onto the site
`in need of fat-reduction may be perform ed prior to locally
`heating the site in need of fat—reduction under 37 °C to
`60 oC. The antifreezing agent could be classified into
`freezing point reduction type and surfactants type. The
`freezing point reduction type antifreezing agent includes
`low-carbon alcohols, diatomic alcohols (polypropylene
`glycol and polyethylene glycol) and amide, etc. The sur-
`factants type antifreezing agent, which brings the mate-
`rialforming a hydrophobic absorbing layer on the surface,
`generally includes acid amine salt of phosphate,
`alkylamine, fatty acid amide, organic acid ester, alkyl suc-
`cimide, etc. This results in protecting the epidermis of
`human body from heating or freezing damage.
`[0010]
`In some embodiments, sucking the site in need
`of fat—reduction to form wrinkles, or alternatively, firstly
`applying antifreezing agent or laying an antifreezing film
`onto the site in need of fat-reduction and then sucking
`the site in need of fat-reduction to form wrinkles are per-
`formed before locally heating the site in need of fat-re-
`duction. This results in blocking the blood circulation be-
`tween the site in need of fat-reduction and other regions
`of human body, which allows limiting the heating and the
`freezing only on the site in need offat-reduction. Thereby
`it decreases heating/freezing time and enhancing the fat-
`reducing effect.
`[0011]
`In some embodiments, the locally heating time
`may be 5 ~ 40 minutes and locally freezing time may be
`40 ~ 120 minutes. Generally, temperature and time of
`locally heating and locally freezing are set up according
`to the environment temperature and thickness of the fat
`layer.
`[0012] According to another aspect of the invention, it
`provides a weight-loss apparatus applying said fat-re-
`duction weight-loss method. The apparatus comprises
`an input unit, a control unit and a heating/freezing unit,

`eration and output a signal representing the user’s
`operation to the control unit;

`nal or a freezing signal to the heating/freezing unit
`according to the received signal representing the us-
`er’s operation;
`
`the heating/freezing unit is configured to receive the
`heating signal ofthe control unit to conduct the heat-
`ing operation, or alternatively to receive the freezing
`signal to conduct the freezing operation.
`
`[0013] The weight-loss apparatus of the invention al-
`lows a complete separation of blood and fat by heating
`the skin and avoids injure oftissue death damage caused
`by the simultaneous solidification of the blood during the
`coolsculpting of the fat.
`[0014]
`In some embodiments, the weight-loss appara-
`tus further includes a mainframe and a working head.
`The input unit is disposed on the surface of the working
`head. The control unit is disposed inside the mainframe
`and the working head. The heating/freezing unit is dis—
`posed in the working head. The working head hasa cavity
`provided with an opening at the lower end thereof and
`an air tap at the upper end thereof. The air tap is con-
`nected to a negative pressure pump disposed in the
`mainframe through an air pipe. The opening of the cavity
`bears against the skin. A motor in the mainframe drives
`the negative pressure pump to suck the skin close to the
`cavity into the inner space of the cavity. This results in
`blocking the blood circulation between the site in need
`of fat-reduction and other regions of human body, which
`allows limiting the heating and the freezing only on the
`site in need of fat—reduction. Thereby it decreases heat—
`ing/freezing time and enhancing the fat—reducing effect.
`[0015]
`In some embodiments, the heating/freezing unit
`may be disposed at the left and right side of the cavity of
`the working head. This results in a uniform heating or
`freezing atthe site in need offat-reduction so as to protect
`the skin from damage caused by concentrated heating.
`[0016]
`In some embodiments, the working head may
`be provided with a handle. This results in facilitating of
`user operation.
`[0017]
`In some embodiments, the control unit may be
`a microcomputer and the heating/freezing unit may be a
`semiconductor cooler. The semiconductor cooler in—
`
`cludes a heat end designed to heat the skin and a cold
`end designed to cool the skin. The semiconductor cooler
`arranged in the cavity of the working head makes the
`weight-loss apparatus safe and environmental friendly
`because the cooler does not have a sliding part and any
`contamination freezing agents.
`[0018]
`In some embodiments, a radiator is provided at
`the back ofthe semiconductor cooler and the mainframe
`
`50
`
`55
`
`is provided with therein a radiating water tank having a
`water inlet and a water outlet connected with a water
`
`pipe. The water pipe coils round atthe back ofthe radiator
`and the radiating water tank is provided with a water
`pump therein such that water in the radiating water tank
`and in the water pipe creates a circulation circuit. The
`water in the radiating water tank out of the water outlet
`flows through the water pipe and absorbs heat of the
`radiator. Then it transfers the heat to the air through the
`pipe at the water inlet and lastly flows into the radiating
`water tank. The radiator is mainly used for decreasing
`the heat of the heat end of the semiconductor cooler and
`
`thereby decreasing the cold end temperature to achieve
`the refrigeration. This results in accelerating of the cool—
`ing rate ofthe semiconductor cooler and allows it to reach
`a lower temperature.
`[0019]
`In some embodiments, the cavity may be made
`from silica gel or soft materials. As a result, the cavity
`can be tightly against the human skin without interspac-
`es, which favors the suction of the skin into the cavity.
`[0020]
`In some embodiments, the cavity may be trans-
`parent. As a result, the changes of the skin in the cavity
`can be observed through the cavity so as to turn off the
`weight-loss apparatus immediately in case of unexpect-
`ed circumstances.
`
`In some embodiments, a temperature sensor
`[0021]
`may be provided in the cavity. The temperature sensor
`can be used for measuring the temperature change of
`the working area (namely, the semiconductor cooler and
`the skin). And controlling ofthe fat-reduction process can
`be achieved according to the temperature change. This
`allows avoiding heating or cooling for too long or too
`short.
`
`In some embodiments, the cavity is provided
`[0022]
`with a LED lamp on the top thereof, which comprises red
`light, green light, blue light and other different colored
`lights. The red LED light is used to increase blood oxygen
`content for the skin in the cavity and promote blood cir—
`culation and metabolism ofthe skin in the cavity so as to
`enhance the effect of the weight-loss apparatus. The
`green LED light is turned on during freezing of the skin
`to effect anti-inflam matory so as to protect effectively the
`skin epidermis from freezing damage.

`[0030] As shown in Fig.3, Fig.4 and Fig.5, the working
`head 2 is provided with a handle 21, a main body 22 and
`a cavity 23 arranged to suck the skin. The handle 21 is
`secured to the back end ofthe body 22. The cavity 23 is
`disposed beneath the main body 22.
`[0031] The input unit A is mounted on the surface of
`the working head 2 and it is particularly an operation key-
`board 221 disposed on the surface of the main body 22.
`Moreover, the control unit B is disposed in the main body

`
`[0032] The cavity 23 is a transparentobject madefrom
`silica gel or soft materials. The bottom of the cavity 23
`opens wide to form an opening 231. On the top of the
`cavity 23 is provided with a LED lamp panel 232 on which
`mounted LED light beads with different colors such as
`red, green, and blue. Inside the cavity 23 is provided with
`a temperature sensor 24.
`[0033] On the top of the cavity 23 is further provided
`with an air tap 233. An air pipe 25 is communicated at
`one end thereofwith the air tap 233 to connect the cavity
`and the air pipe 25. The other end of the air pipe 25
`passes through the main body 22 of the working head 2
`and is connected with the negative pressure pump dis—
`posed in the mainframe 1.
`[0034] The heating/freezing unit C is a semiconductor
`cooler 26 which is disposed at the left and right side of
`the cavity 23. The semiconductor cooler 26 includes a
`heatend and a cold end in which the heat and is arranged
`to heat the skin and the cold end is arranged to cool the
`skin.
`
`[0035] The semiconductor cooler 26 is provided with
`a radiator 27 at the back side thereof and a water pipe
`coils round at the back side of the radiator 27. The water
`
`pipe 28 is communicated at one end thereof with the wa—
`ter inlet of the radiating water tank in the mainframe 1
`through the main body 22 of the working head 2 and at
`the other end thereofwith the water outletofthe radiating
`water tank in the mainframe 1 through the main body 22
`of the working head 2.
`[0036] The bourdon tube 3 is connected at one end
`thereofwith the mainframe 1 and at the other end thereof
`
`with the working head 2. The air pipe 25, the water pipe
`28 and other data wires connecting the mainframe 1 and
`the working head 2 are all packaged in the bourdon tube
`3.
`
`[0037] When in operation, one first applies antifreezing
`agent or lays an antifreezing film onto the site of skin in
`need of fat-reduction. Then allow the opening 231 of the
`cavity 23 of the working head 2 to bear against the skin
`so as to form a closure space with the skin. The anti-
`freezing agent is alkylamine in this embodiment. In other
`embodiments, however, the antifreezing agent may be
`low-carbon alcohols, diatomic alcohols (polypropylene
`glycol and polyethylene glycol), amide, acid amine salt
`of phosphate, alkylamine, fatty acid amide, organic acid
`ester or alkyl succimide.
`[0038] Next, turn on the mainframe 1 and allow the
`motor to drive the negative pressure pump. At this time,
`the circulation system ofthe radiator 27 and the radiating
`water tank is shutoff. The air in the closure space formed
`between the cavity 23 and the skin is sucked out through
`the air pipe 25 by the negative pressure pump. Under
`the negative pressure, the skin is sucked into the cavity
`23 and forms wrinkles. Thus, the blood circulation be-
`tween the sucked skin and the other region of skin is cut
`off.

`
`keyboard 221 will make the control unit B send out a
`heating signal. Atthis time, the skin is heated by the sem—
`iconductor cooler 26 and the red LED light. The temper-
`ature data in the cavity 23 is transmitted to the control
`unit by the temperature sensor 24 and then displayed on
`the display screen 13. The temperature in the cavity 23
`is controlled as 37~60°C(for exam ple 45°C). Continuous-
`ly heating of the skin accelerates the blood circulation of
`the skin in the cavity 23. Heating of the skin continues
`for 5~4O minutes (for example 10 minutes) until the blood
`and the muscles separate with the fat. Such an internal
`change situation of the skin can be detected by a device
`like B mode ultrasound device mounted in the cavity 23.
`This device transmits a signal representing the internal
`change situation of the skin to the control unit and the
`signal is displayed on the display screen 13. Thus, the
`internal change situation of the skin can be observed by
`the display screen 13 so as to facilitate judging whether
`the blood and the muscles are separated completely with
`the fat.
`
`[0040] Upon the above heating step is finished, a
`pause for about 1 minute is taken. Then, the circulation
`system ofthe radiator 27 and the radiating water tank as
`well as the LED lamp are turn on to locally freeze the site
`in need offat—reduction under—10 °C to 5°C (e.g. at 5°C)
`for 40~120min (e.g.45min) until the fat solidifies. Finally,
`the mainframe 1 is turned off to let air enter the cavity 23
`such that the skin recoveries. The whole fat-reduction
`
`process is accomplished.
