Description

Medical cryogenic

The present invention relates to a medical cryostat, and more specifically, to improve the heat dissipation efficiency by integrating the cooling unit, the suction unit, and the heat dissipation unit, the anti-frostbite pad detecting unit for detecting an anti-frostbite pad is installed directly on the cooling plate. The present invention relates to a medical cryogenic device that can be prevented and miniaturized to be easy to carry and thus convenient to use.

In general, it causes various effects such as pain relief, vasoconstriction, and inflammatory response by inducing cooling of the skin of local parts of the human body. Various low temperature devices that can induce such cooling effect have been researched and developed, but no appropriate tools have been suggested. In some cases, it is only used in limited areas.

In particular, the skin cooling method is used for skin disease treatment and laser treatment, but the cooling device used for the treatment of skin disease is a cooling device using the vaporization heat of liquid nitrogen. In addition, there is a disadvantage in that it is very inconvenient to use due to time constraints according to the vaporization rate.

In addition, a compressor-type cooler using freon gas as a refrigerant is a method of directly contacting a probe of a metal material to the skin, and thus, temperature control is impossible, and it maintains only a very low temperature of about 15 degrees to minus 20 degrees. The temperature of about 10 degrees could not be maintained.

Recently, a low temperature device using a thermoelectric element is proposed as a next-generation cooling method that breaks the existing cooling method that operates a compressor to circulate a refrigerant, and is capable of simultaneously cooling and heating at any time through pole switching.

A thermoelectric element is a device formed by combining two different metals of the same shape or by bonding an n-type semiconductor and a p-type semiconductor to each other. When a direct current is applied to the device, endothermic reactions and heat radiation reactions occur on both metal surfaces. Will have. Therefore, when the heat exchanger is installed on the heat absorbing portion of the thermoelectric element, the surrounding space can be cooled. On the contrary, when the heat exchanger is installed on the heat radiating portion, the temperature of the surrounding space can be increased.

Since the thermoelectric element does not use a refrigerant using a conventional refrigeration cycle, there is no need for a driving device such as a compressor, and thus there is no operation noise, and the thermoelectric element has a feature of being very easy to install due to its small size.

Therefore, the heat absorbing part of the thermoelectric element is disposed toward the space to be cooled, and the heat radiating part is disposed on the opposite side to adjust the magnitude and time of the current supplied to the thermoelectric element, thereby allowing the refrigerator to be refrigerated or frozen. It can be used for such products as.

The cooler using the above principle has been researched and developed, and in particular, a skin cooler using a thermoelectric element (Domestic Application No. 2002-63368) and a medical cooler using a thermoelectric semiconductor (Korean Patent Publication No. 0697956) have also been filed. .

In addition, these conventional skin coolers have no side effects among various techniques for the treatment of obesity, and the cooling lipolysis procedure, which is painless during the procedure, is used favorably as a new treatment method. The cooling lipolysis machine inhales the treatment site to absorb the heat energy of the treatment site. In principle, the suction and the discharge part may include a suction part for contacting the surgical part with a cooling part, a cooling part for cooling the surgical part, and a heat dissipation part for transferring heat energy transferred to the cooling part to the outside.

In the case of the conventional medical cooler that cools the skin to break down fat, the suction part, the cooling part, and the heat dissipation part are mechanically separated and difficult to carry. Accordingly, the heat loss is high, and the equipment is very large mechanically. there was.

In addition, the frostbite prevention pad must be used for the treatment site, but there was a problem that the user suffers from frostbite because the procedure is not performed using the frostbite prevention pad.

As shown in FIGS. 1 to 8, the medical cryocooler 1000 according to the embodiment of the present invention is provided with a grill to have a flow of air, and a case 1100 in which the control operation unit 1600 is located at one outer surface. And a suction unit 1300 installed inside the case to form a vacuum pressure by a motor or a pump, and a suction unit 1300 installed inside the case and communicating with a lower portion of the vacuum suction unit. And a cooling unit 1400 installed on both sides of the suction unit to deprive heat of the skin, and disposed between the case and the vacuum suction unit and the suction unit, and being in contact with the cooling unit to heat the case. It includes a left and right heat dissipation unit 1500 installed to discharge in one direction.

Therefore, when the operation part of the user is placed in the state in which the frost-preventing pad (not shown) is mounted on the suction unit 1300 and the control operation unit 1600 is operated to operate the medical low temperature device 1000, the vacuum suction unit 1200 is operated. During operation, a vacuum is generated in the suction unit 1300, and the vacuum sucks the surgical site in close contact with the suction unit 1300, and the surgical site is in close contact with the cooling unit 1400 to take heat from the surgical site to dissipate heat. The heat is emitted to the 1500, and at this time, the cooled treatment area in contact with the cooling unit 1400 causes the fat to be decomposed.

Here, the case 1100 is located on the outer side of the vacuum suction unit 1200, the carrier ring 1160 and the silicon pad 1170 is provided on the outer surface of the left body case 1110 having an air flow path (1111). And a right body case 1120 having an air flow path 1121 and a control manipulator mounting groove 1122 formed so that the control manipulator 1600 protrudes while being positioned outside the vacuum suction unit. And a cover 1130 installed at an upper portion of the right body case and having an air flow path 1131, and first and second grills 1140 installed at the sides of the left body case and the right body case to form an air passage. , 1150).

Therefore, when air is discharged from the vacuum suction part 1200, the vacuum is discharged to the suction part 1300 while being discharged to the outside of the case 1100, and the heat taken from the cooling part 1400 is the heat dissipation part 1500. Through the discharged to the outside of the case 1100.

The cooling unit 1400 is installed to protrude to the inner surface of the suction unit 1300, and has an insulating surface 1411 plated to be insulated from the outer surface, and an insulating surface is removed from one side of the insulating surface. A pair of cooling panels 1410 having an in-phase preventing pad detecting unit 1412 that is an energized surface, and a thermoelectric element 1420 connected to the cooling panels to discharge heat to the heat radiating unit.

Therefore, when the suction unit 1300 is placed on the surgical site without mounting the anti-frostbite pad on the suction unit 1300, the surgical site directly contacts the cooling panel 1410, thereby causing frostbite. When the liquid-coated frostbite prevention pad is not used, the frostbite prevention pad detection unit 1412 is not energized so that the vacuum suction unit 1200 does not operate so that the control operation unit 1600 is configured to cause frostbite around the circumference. To prevent it.

That is, the anti-frost pad is mounted on both sides of the anti-frost pad detection unit 1412 of the cooling panel 1410 installed inside the suction unit 1300 so that both ends are in contact with the suction unit 1300 at the surgical site to control the control unit ( When the 1600 is operated, the liquid deposited on the frostbite prevention pad acts as a conductor and operates by energizing the frostbite prevention pad detection unit 1412 of both cooling panels 1410, so that the procedure is operated without using the frostbite prevention pad. There is a double safety device that prevents frostbite in the area in advance.

In addition, the in-phase prevention pad detection unit 1412 is used as a sensing unit for the detection of electricity by removing the insulating surface, so that the cooling panel 1410 is used as a sensor instead of a separate sensor, so as to ensure the safety of consumers and manufacture. In terms of cost reduction, productivity is improved.

The heat dissipation unit 1500 may include a heat block 1510 that receives heat from the cooling unit, a heat dissipation fin 1520 that receives heat from the heat block, and a heat dissipation fin that is fixed to an outer surface of the heat dissipation fin. The cooling fan 1530 is installed to discharge the heat of the outside and the heat pipe 1540 connected to the heat block and the heat radiation fins to transfer heat from the heat block to the heat radiation fins integrally.

Therefore, the heat block 1510 is connected to the thermoelectric element 1420 of the cooling unit 1400 receives heat and transfers the heat to the heat dissipation fin 1520 through the heat pipe 1540, and the two heat dissipation units 1500 Each of the cooling fan 1530 provided at the) is rotated in one direction so that the heat of each of the heat dissipation fins 1520 can be easily discharged to the outside, as well as the heat block 1510 and the heat dissipation fins. The 1520 and the cooling fan 1530 and the heat pipe 1540 may be integrated to reduce the size of the device, thereby reducing the restriction on the time and place of the procedure, thereby enabling the use of the medical cryostat.

On the other hand, the in-phase prevention pad detection unit 1412 is formed on the vacuum suction side, it is prevented from being energized by the surgical site to prevent a malfunction occurs.
