The cooling medium accommodating part 111 may be made of a metal material having high thermal conductivity in order to efficiently transmit cooling energy. The cooling medium accommodating part 111 may function as a cooling distributor for dispersing the cooling energy collected from the cooling generating part 113 in a wide area in a relatively narrow area. Through such a cooling distributor function, the cooling energy generated by the cooling generator 113 is effectively transferred to the cooling medium 20. The cooling medium accommodating part 111 may include a plurality of split units 1111 having a contact surface thermally coupled to the cooling medium 20.

Although not shown, the cooling medium accommodating part 111 may be provided with a lubricating member to easily accommodate the cooling medium 20 that is detachably provided.

In the present specification, the cooling energy is a concept opposite to the movement of heat, and the cooling is actually lowering the temperature of the object through an endothermic reaction, but for the convenience of description, cooling the object through the transfer of cooling energy. Let's define.

The cooling generator 113 may be in any form capable of supplying cooling energy to the cooling medium accommodating part 111, and may include one or more cooling elements capable of generating cooling energy. One or more cooling elements may be disposed on the other surface of the plurality of dividing units 1111. The cooling element uses a thermodynamic cycle such as a stirling cooler or vapor compression refrigeration cycle, liquid evaporation, or Joule-Thomson method with expansion gas. To generate cooling energy. In addition, the cooling device may generate cooling energy using liquid nitrogen or carbon dioxide, or may supply cooling energy using a thermoelectric device such as a Peltier device. There is no restriction on the cooling method of the cooling device in the present invention, but for the convenience of description, the following description will be given with reference to the case of using a thermoelectric device.

When the cooling generating unit 113 uses a thermoelectric element, when a current is applied to the thermoelectric element, due to the Peltier effect, the surface in contact with the cooling medium accommodating portion 111 in the thermoelectric element generates heat absorption, and the heat dissipation portion in the thermoelectric element Surfaces in contact with 114 may generate heat. As a result, heat in the region where the cooling medium 20 contacts the object is transferred to the cooling generating unit 113 through the cooling medium 20 and the cooling medium accommodating part 111, and the heat is radiated later. Via 114 may be emitted to the outside.

The heat radiating unit 114 may discharge the heat generated from the cooling generating unit 113 to the outside. The heat dissipation unit 114 may also be referred to as a heat sink, a heat dissipation unit, a heat dissipation unit, a heat dissipation unit, and the like. The heat dissipation unit 114 may be made of a thermally conductive material in order to efficiently discharge the heat generated during the cooling generation unit 113 to generate the cooling energy. The heat dissipation unit 114 may be combined with two or more heat dissipation units, and may be divided into a number corresponding to the number of the plurality of dividing units 1111.

The heat radiating unit 114 may be disposed to be spaced apart from the cooling generating unit 113, and may be thermally coupled to the cooling generating unit 114 to release heat from the cooling generating unit 113 to the outside. The heat dissipation unit 114 may be disposed at the rear of the cooling medium accommodating part 111 and may be thermally coupled to the cooling generation unit 113 through the heat transfer medium 116.

The heat dissipation unit 114 may include a plurality of heat dissipation fins 1141, and the heat dissipation fins 1141 may be spaced apart from each other along the longitudinal direction of the first body part 100A. At this time, the heat radiation fins 1141 may be provided in a predetermined number per unit length, for example, may be provided to have a numerical range of 0.5 or more than 1.5 mm / mm or less. When the heat dissipation fins 1141 are provided with less than 0.5 pieces / mm, the heat transfer area with the fluid is reduced to reduce heat dissipation efficiency. In addition, when the heat dissipation fins 1141 are provided to exceed 1.5 / mm, the heat dissipation efficiency is inevitably deteriorated because the interval through which the fluid can flow is too narrow. Accordingly, the heat dissipation unit 114 may maximize the heat dissipation effect by arranging the heat dissipation fins 1141 to have a numerical range of 0.5 / mm or more and 1.5 / mm or less.

The blower 150 may be disposed inside the body 100 to form a flow of unidirectional air. The blower 150 sucks outside air to cool the heat radiating unit 114 using the outside air, and then discharges the air.

Specifically, the medical cooling device 10 has an air flow in a direction that is not parallel to the longitudinal direction of the first body portion (100A) in the state provided with a blower 150 consisting of at least one fan between two heat radiation fin rows. This can be formed. In other words, the blower 150 may form an air flow in a direction that is not parallel to the axial direction of the heat dissipation unit 114. Specifically, the medical cooling device 10 may be formed in the air flow in the direction perpendicular to the longitudinal direction of the first body portion (100A). By forming a blower between the two heat radiation fins formed of the heat radiation fins 1141, the passage through which the air flows is formed over a large area, and is formed at a short distance, thereby maximizing heat transfer between the heat radiation fins 1141 and the air. In addition, when the blower 150 includes a plurality of fans, the arrangement direction of the plurality of fans and the axial direction of the heat dissipation unit 114 may be parallel, and the arrangement direction of the plurality of fans and the rotation axis direction of the fans cross each other. can do.

The heat transfer medium 116 may be a heat pipe or a vapor chamber, and may include a pipe body and a phase change material (PCM) provided inside the pipe body. The pipe body of the heat transfer medium 116 may be made of a material having a high thermal conductivity so as to be in contact with the cooling generator 113 and to effectively transfer heat generated from the cooling generator 113 to an internal phase change material (PCM). Phase change material (PCM) is a material that stores a lot of heat energy or release the stored heat energy through the phase change process, the phase change material has a unique heat storage capacity.

Meanwhile, the heat transfer medium 116 may be a pipe including a fluid forcibly flowing by a pump or the like. In other words, the heat transfer medium 116 may be thermally coupled to the second surface 113B of the cooling generator 113 through one region A1 to absorb thermal energy from the cooling generator 113. In addition, the heat transfer medium 116 is thermally coupled to the heat dissipation unit 114 through the other area A2 extending from the one area A1 in the longitudinal direction (first direction) of the cooling medium accommodating part 111, It is possible to release absorbed thermal energy. Here, the other area A2 of the heat transfer medium 116 may be non-overlapping with the cooling medium accommodating part 111.

Medical cooling apparatus 10 according to the present embodiment by using the heat transfer medium 116 containing a phase change material, to effectively transfer the heat generated from the cooling generating unit 113 to the heat dissipating unit 114 to the outside It can be released. That is, the amount of cooling energy generated per unit area of the thermoelectric element used in the cooling generating unit 113 may be greatly increased when the heat transfer medium is used through the heat transfer performance per unit area of the heat transfer medium 116, which is significantly larger than that of simple copper. Can be. As a result, the cooling medium accommodating part 111 may effectively transmit cooling energy to the cooling medium 20 even through a small contact area, thereby increasing the degree of freedom with respect to the length of the cooling medium 20.

On the other hand, the medical cooling device 10 may further include a pressure sensor unit 141 for generating a pressure signal by detecting the pressure applied when the cooling medium 20 in contact with the surgical site of the object. The pressure sensor unit 141 may be disposed on the cooling medium receiving unit 111 or another component capable of detecting the pressure caused by the contact of the cooling medium 20 to sense the pressure applied from the cooling medium 20. have.

Meanwhile, the medical cooling apparatus 10 may further include a temperature sensor unit 145 for detecting a temperature of the cooling medium 20 or the cooling medium accommodating part 111. The temperature sensor unit 145 may be connected to the cooling medium receiving unit 111 to sense a temperature or may be disposed at a position in direct contact with the cooling medium 20 to sense a temperature of the cooling medium 20. In addition, when the cooling medium 20 is configured to be replaced, the temperature sensor unit 145 for measuring the temperature of the cooling medium 20 may be configured as a non-contact temperature sensor, for example, an infrared sensor.

Thus, a plurality of cooling generation units 113 such as thermoelectric elements may be provided, and the heat transfer medium 116 such as heat pipes corresponding to the cooling generation units 113 may be symmetrical.

The heat transfer medium 116 is connected to the heat dissipation unit 114, the heat dissipation unit 114 is composed of a plurality of heat dissipation units, more specifically, the heat dissipation unit and the blower provided on the inlet side of the blower It may be configured as a heat dissipation unit provided in the outlet.

In the correspondence of a plurality of heat transfer medium units symmetrically configured and a plurality of heat dissipation units symmetrically configured, the plurality of heat transfer medium units corresponding to the division unit may be symmetrically connected to the inflow side heat dissipation unit and the outflow side heat dissipation unit. It is preferable to construct.

In the heat dissipation unit, even though the physical structure is symmetrical, the heat dissipation effect may be asymmetric. That is, in the heat dissipation effect of the heat dissipation part 114, the heat dissipation effect of the inflow side heat dissipation part through which air flows in and the heat dissipation effect of the outflow side heat dissipation part through which air flows out are different. According to the present invention, the heat transfer medium unit corresponding to one division unit is configured to be connected to the air inlet side heat dissipation unit and the air outlet side heat dissipation unit, respectively, so that the heat dissipation effect is asymmetric using a heat dissipation unit, which is asymmetric. It is possible to dissipate the cooling generating part efficiently and efficiently.

Specifically, referring to FIGS. 3A to 3C, the medical cooling apparatus 10-1 may include a cooling medium accommodating part 111 that is thermally coupled to the cooling medium 20. The cooling medium accommodating part 111 may include a plurality of split units 1111A and 1111B having a contact surface in thermal contact with the cooling medium 20. In one embodiment, the cooling medium accommodating part 111 is interposed between the cooling medium 20, and is arranged to be symmetrical in one direction (y direction in FIG. 3C) and the second partitioning unit 1111A and the second partitioning unit ( 1111B).

As shown in FIG. 3C, a portion of the first split unit 1111A and the second split unit 1111B may overlap with the cooling medium 20. In this case, the cooling generator 113 may be non-overlapping with the cooling medium 20 of the first split unit 1111A and the second split unit 1111B and may be disposed in a portion extending along the longitudinal direction (x direction). have. The first dividing unit 1111A and the second dividing unit 1111B are symmetrically arranged, and are formed in the same structure. Hereinafter, the first dividing unit 1111A will be described based on the first dividing unit 1111A.

In one embodiment, two cooling units 113 corresponding to one first split unit 1111A may be provided. For example, as shown in the figure, the cooling generating unit 113 is symmetrically disposed in the z direction with respect to the first dividing unit 1111A, and the heat dissipating unit 114 through the heat transfer medium 116, respectively. Heat transfer can occur. The heat transfer medium 116 transfers heat from the cooling generating unit 113 to the heat radiating unit 114 to perform a function of radiating the cooling generating unit 113.

Meanwhile, the medical cooling apparatus 10-1 may include a blower 150 formed of a plurality of fans. The blower 150 may generate a fluid flow in the first direction (z direction). Here, the first direction (z direction) may cross the longitudinal direction (x direction) of the heat dissipation unit 114. Since the heat dissipation part 114 has a structure extending in the longitudinal direction (x direction), the width in the first direction (z direction) may be smaller than the length in the longitudinal direction (x direction). Therefore, since the fluid is introduced through a large area of the heat dissipation unit 114 and then flows out through a shorter distance, the heat dissipation efficiency of the heat dissipation unit 114 can be maximized. At this time, the thickness of the fan constituting the blower 150 is composed of 25mm or less, by minimizing the fluid passage distance in the heat radiating portion 114 in the first direction (z direction), The heat dissipation efficiency can be maximized.

On the other hand, when the blower 150 is composed of a plurality of fans, the plurality of fans may generate the fluid flow in the same direction, as another embodiment, may also generate the fluid flow in the opposite direction to each other. For example, when the blower 150 includes four fans, if the two fans generate the flow of the fluid in the z direction, the remaining two fans may generate the flow of the fluid in the -z direction. Through such a blowing method, the medical cooling apparatus 10-3 may dissipate the cooling generator 113 in a balanced and efficient manner. However, hereinafter, for convenience of description, a description will be given based on the case where the plurality of fans generate the fluid flow in the same direction.

The heat dissipation unit 114 may be formed of a plurality of heat dissipation units. In one embodiment, the heat dissipation unit 114 may include a plurality of heat dissipation units corresponding to the number of heat transfer mediums 116. In another embodiment, the heat dissipation unit 114 may include a first heat dissipation unit 114A and a second heat dissipation unit 114B disposed symmetrically with respect to the blower 150 in the first direction z. Can be. When the blower 150 generates the flow of the fluid in the first direction z, the first heat dissipation unit 114A corresponds to the inflow side heat dissipation unit, and the second heat dissipation unit 114B is connected to the outflow side heat dissipation unit. This may be the case. However, since the position of the inflow side heat dissipation unit and the outflow side heat dissipation unit may vary depending on the flow direction of the fluid generated by the blower 150, the present invention is not limited to the fluid flow direction shown in the drawings.

As described above, even if the heat dissipation unit 114 has a physically symmetrical structure, the heat dissipation effect of the first heat dissipation unit 114A, the inflow side heat dissipation unit, and the second heat dissipation unit 114B, the outflow side heat dissipation unit, Can be different. Specifically, in the case of the inlet side heat dissipation unit, the external cool fluid flows in continuously, whereas in the case of the outflow side heat dissipation unit, the fluid that is relatively hot than the external fluid passes through the heat transfer of the heat dissipation unit 114. Therefore, the heat dissipation effect of the inlet side heat dissipation unit may be relatively large compared to the heat dissipation effect of the outflow side heat dissipation unit.

In this case, the first split unit 1111A may be symmetrically connected to the first heat dissipation unit 114A and the second heat dissipation unit 114B by the plurality of heat transfer media 116. For example, the first split unit 1111A is connected to the first heat dissipation unit 114A through the first heat transfer medium 1116 in a state where the cooling generator 113 is interposed therebetween, and the second heat transfer medium (11A). 1163 may be connected to the second heat dissipation unit 114B. Therefore, one first split unit 1111A may be connected to both the first heat dissipation unit 114A and the second heat dissipation unit 114B having an asymmetric heat dissipation effect, and thereby balance thermally with the cooling medium 20. Combination may be possible.

Similarly, the second split unit 1111B may also be connected to both the first heat dissipation unit 114A and the second heat dissipation unit 114B using the second heat transfer medium 1162 and the fourth heat transfer medium 1164. The cooling medium accommodating part 111 may transmit cooling energy symmetrically to the cooling medium 20 using the first split unit 1111A and the second split unit 1111B which are symmetrically disposed. Through this, the cooling medium 20 can cool the target area efficiently and efficiently without variation in the degree of cooling.

IV. Cooling medium and cooling tip structure and function

4A and 4B are views for explaining the concentrated cooling structure using the cooling medium. Hereinafter, the cooling medium 20 of the medical cooling system 1 will be described.

Figure 4a is a perspective view showing a removable cooling medium 20 according to an embodiment of the present invention, Figure 14b to illustrate a concentrated cooling structure using a removable cooling medium 20, a portion of a medical cooling apparatus is shown Drawing.

Basically, the removable cooling medium 20 and the medical cooling system 1 including the same according to an embodiment of the present invention have a large area through the cooling medium accommodating part 111 consisting of a single or a plurality of split units 1111. By collecting the cooling energy in, to concentrate it in a narrow area of the front end portion 225 of the removable cooling medium (20). Through this, the medical cooling system 1 can perform cooling anesthesia by effectively cooling the surgical site. At this time, the removable cooling medium 20 is easily separated from the medical cooling device 10, characterized in that to minimize the risk of infection.

The function of the removable cooling medium 20 is primarily to perform cooling on a target area such as an eyeball. In the present specification, the cooling medium 20 may be detachably mounted to the medical cooling device 10 and may be a removable cooling medium provided as a disposable. However, the spirit of the present invention is not limited thereto, and the cooling medium 20 is a component that is accommodated in the medical cooling apparatus 10 to perform a cooling function and does not necessarily need to be detachably provided. However, hereinafter, for the convenience of description, a cooling medium, a removable cooling medium, and a disposable cooling medium may be used in combination, and all will be described as referring to the same component.

Referring to FIG. 4A, the removable cooling medium 20 may include an insertion region 210 and a non-insertion region 220. The removable cooling medium 920 may be inserted into the cooling medium accommodating part 111 of the medical cooling apparatus 10 through the insertion region 210. In addition, the removable cooling medium 20 may perform a cooling function by contacting the target area through the tip portion 225 provided in the non-insertion area 220.

Insertion region 210 is inserted into the medical cooling device 10, specifically, the cooling medium receiving portion 111 to perform the function of transferring the cooling energy delivered from the cooling medium receiving portion 111 to the non-insertion region 220. do. The insertion region 210 may receive cooling energy through an area of the outer surface S2 that is in thermal contact with the cooling medium accommodating portion 111.

The non-insertion area 220 may include a tip portion 225 that is not inserted into the medical cooling apparatus 10 and thermally contacts the target area at the end E1. The non-insertion area 220 may extend along the axial direction AX1 from the insertion area 210 and may be formed to have a smaller diameter toward the end E1. When viewed in a cross section parallel to the axial direction AX1 may be formed to be tapered to some extent.

The tip 225 provided at the distal end E1 of the non-insertion area 220 is in contact with the target area such as the eyeball, and inserts the cooling energy generated by the cooling generation unit 113 of the medical cooling device 10 as described above. Received from the area 210 serves to cool the target area. In other words, the tip 225 serves to cool the target area by contacting the target area such as the eyeball and transferring heat of the target area to the medical cooling apparatus 10.

Although the shape of the tip portion 225 is circular in the figure, the spirit of the present invention is not limited thereto, and may be formed in various forms that can efficiently cool by contacting the target region. In addition, the area S1 of the tip portion 225 may be formed to be equal to the area of the target area such as an eyeball or smaller than the area of the target area. In this way, the removable cooling medium 20 allows cooling to be performed intensively at the localized area.

Meanwhile, the removable cooling medium 20 may be made of a material having high thermal conductivity in order to effectively transmit cooling energy from the medical cooling device 10. For example, the removable cooling medium 20 may include gold (Ag) and silver. (Au), copper (Cu), aluminum (Al), and the like. In addition, although the insertion region 210 and the non-insertion region 220 are illustrated as being integrally formed in the drawing, the insertion region 210 and the non-insertion region 220 may be manufactured by combining separate components, respectively. . In addition, the insertion region 210 and the non-insertion region 220 may be made of the same material, but may also be made of different materials. In addition, the tip portion 225 may be coated with a material containing a hydrophobic polymer, thereby minimizing the formation of ice crystals by cooling. Here, the insertion region 210 and the non-insertion region 220 of the removable cooling medium 20 may serve as a kind of heat flux distributor.

On the other hand, the length or structure of the cooling medium may be changed according to the target area, that is, the procedure or the surgical site. When the length of the cooling medium is long for smooth contact with the target area, the removable cooling medium may be a heat pipe. It can be implemented as a heat transfer medium. Through this structure, it is possible to minimize the temperature difference at the tip of the shape.

According to one embodiment, when the cooling medium is implemented as a disposable tip of the heat pipe structure, for example, it is composed of a heat pipe corresponding to the thermal conductivity of 5000 W / mK, it is possible to minimize the performance degradation despite the long shape have.

In addition, since the heat pipe operates in a cooling or freezing environment, it is preferable to implement a heat pipe using a refrigerant operating at a temperature below freezing point, for example, when ethylene glycol is used as the refrigerant, By adjusting the concentration, the freezing point of the refrigerant can be optimized corresponding to the cold treatment site. In addition to the ethylene glycol, the freezing point can be optimized using various other refrigerants such as ammonia or methanol, which are heat pipe refrigerants suitable for freezing below the freezing point. For example, the operating temperature range of the heat pipe may be the second temperature range, and as described below, depending on the purpose of the procedure, -90 ° C or more and 0 ° C or less or -50 ° C or more and 0 ° C It may have the following ranges.

On the other hand, referring to Figure 4b, the removable cooling medium 20 according to an embodiment of the present invention collects the cooling energy in a large area through the cooling medium receiving portion 111 consisting of a single or a plurality of split units 1111. Thus, it concentrates on a narrow area of the tip portion 225 of the removable cooling medium 20. In this case, the removable cooling medium 20 may include a cooling concentration portion CO1 protruding to the outside from the surface of the tip portion 225 in one region of the tip portion 225.

As described above, the removable cooling medium 20 concentrates the cooling energy collected through the large area in the narrow area of the tip portion 225. In particular, the removable cooling medium 20 has a structure that protrudes outward from the tip portion 225. By further providing CO1, the cooling energy can be further focused through a narrow area of the cooling concentrator CO1. In addition, since the cooling concentration portion CO1 protrudes outward from the tip portion 225, when the operator contacts the tip portion 225 of the removable cooling medium 20 with the treatment portion, the target portion through the protruded portion of the target region. Maximum pressure may be applied at the corresponding position. Therefore, the cooling concentrator CO1 may transmit the maximum cooling energy to a corresponding position in comparison with other regions of the tip portion 225.

Here, the position corresponding to the cooling concentration portion CO1 of the target region may coincide with the scanning position. That is, the cooling concentrator CO1 transmits the maximum cooling energy to the position to be scanned in the target region, thereby enabling anesthesia more effectively at the position where the pain occurs due to the actual needle.

To this end, as an embodiment, the cooling concentration unit CO1 may be formed of a protrusion located at the center of the tip portion 225. In FIG. 14, the cooling concentrator CO1 is formed in the shape of a protrusion without a hole through which the needle passes through the tip 225. However, the present invention is not limited thereto, and in another embodiment, when the removable cooling medium 20 stores a chemical liquid and uses a needle that is injected into the cooling medium 20 to inject the chemical liquid into a cartridge, the distal end portion may be provided. In 225, a through hole through which the needle passes may be formed, and in this case, the center of the cooling concentration unit CO1 may coincide with the center of the needle. In other words, the cooling concentrating portion CO1 may be formed by a structure in which the peripheral portion adjacent to the through hole through which the needle passes is formed to protrude outwardly compared to other regions of the tip portion 225.

In addition, the cooling concentration unit CO1 may have a protrusion shape in which the cross-sectional area decreases from the front end portion 225 toward the outside. However, the present invention is not limited thereto, and the cooling concentrator CO1 may have a constant cross-sectional area with respect to the protruding direction protruding to the outside. In addition, the cross section of the cooling concentrating portion CO1 in the protruding direction may have various shapes, and for example, may be made of any one of a square, a triangle, and a circle.

As described above, in the removable cooling medium 20 according to the embodiment of the present invention, the cooling concentrating portion CO1 having the protrusion structure is formed at the tip portion 225, thereby concentrating on the injection site and delivering the maximum cooling energy. Thus, the effect of cooling anesthesia can be maximized.

The second chemical liquid storage unit 250 may push the second chemical liquid 251 accommodated therein by moving the first chemical liquid storage unit 240 to the outside. Here, the first chemical 241 and the second chemical 251 may be different drugs. For example, the first chemical liquid 241 may include a therapeutic agent, and the second chemical liquid 251 may include a disinfectant.

Hereinafter, the drug injection process of the removable cooling medium 20 according to the actuator operation will be described with reference to FIGS. 5C and 5D.

First, the removable cooling medium 20 is inserted into the cooling medium accommodating part 111 of the medical cooling apparatus 10 to be in a state as shown in FIG. 5C. In the state as illustrated in FIG. 5C, when the second injection unit 1631 moves linearly in the direction of arrow A, the second injection unit 1631 and the first injection unit 1611 move together to form the first chemical storage unit ( 240) is pushed out. At this time, the injection needle 247 disposed at one end of the first chemical storage unit 240 is also moved together, and the injection needle 247 is inserted into the needle hole H1 while the sealing membrane 207 is inserted.

As described above, the medical cooling system 1 according to the embodiments of the present invention can perform a rapid cooling action by supplying intensive cooling energy to a cooling medium that performs cooling in contact with the surgical site. In addition, the medical cooling system 1 according to the embodiments of the present invention can inject the drug solution after local anesthesia through the cooling, thereby reducing the pain of the patient.

The medical cooling system 1 having the above configuration may control the temperature through the controller 170 to cool the target area according to the purpose.

Hereinafter, the cooling protocol using the temperature control according to the multi-step by using the control unit 170 will be described.

The controller 170 may control the operation of the cooling generator 113 based on the temperature detected by the temperature sensor unit 145. For example, the controller 170 may perform cooling anesthesia based on the ambient air temperature provided from the temperature sensor unit 145, the temperature of the cooling medium 20, or the air temperature and the temperature of the cooling medium 20. Can be controlled. The controller 170 may adjust the temperature of the cooling medium 20 by controlling the operation of the cooling generator 113 based on the temperature measurement signal provided from the temperature sensor unit 145. Specifically, the medical cooling system 1 according to the embodiments of the present invention may control the cooling medium 20 by selectively setting the temperature range according to the purpose in the temperature range of -100 ℃ to 15 ℃. Through the temperature control described above, the medical cooling system 1 may perform a cooling operation while controlling the surface of the treatment site in a temperature range of -50 ° C to 15 ° C.

In addition, the controller 170 may control the cooling generator 113 to maintain the cooling medium 20 at a constant temperature during the time of performing the cooling anesthesia. In another exemplary embodiment, the controller 170 controls the cooling generator 113 so that the cooling medium 20 has the respective temperature values sequentially or periodically during the time at which two or more temperature values are set in advance. can do.

When the controller 170 exceeds a preset temperature or time, the controller 170 may prevent excessive cooling of the surgical site by controlling the power of the cooling generator 113 to be turned off. This is only one embodiment, and of course, the temperature and time can be preset in various ranges.

Herein, the controller 170 may include all kinds of devices capable of processing data, such as a processor. Here, the 'processor' may refer to a data processing apparatus embedded in hardware having, for example, a circuit physically structured to perform a function represented by code or instructions included in a program.

The controller 170 may receive the pressure measurement signal from the pressure sensor unit 141, and determine that the tip 225 of the cooling medium 20 has contacted the patient's surgical site when the pressure measurement signal is greater than a preset reference value. At this time, the control unit 170 may check the time and temperature measurement signal during contact with the treatment site of the patient, and may determine that anesthesia has been completed at the treatment site of the patient when cooled to a predetermined range of temperature for a predetermined time. .

FIG. 5E is a conceptual diagram for explaining an entire temperature protocol using a medical cooling system, and FIG. 5F is a diagram for explaining an attaching step (S-1) in the total temperature protocol of FIG. 5E. 5G and 5H are diagrams for explaining the detaching step S-4 in the overall temperature protocol of FIG. 5E, and FIG. 5I is a diagram for explaining the drying step S-5 in the overall temperature protocol of FIG. 5E. to be.

5E, the overall temperature protocol using the medical cooling system according to another embodiment of the present invention is an attaching step (S-1), cooling disinfection step (S-2), cooling anesthesia step (S-3), It may include a detacking step (S-41, S-42) and a drying step (S-5). The height difference of each step shown in the figure represents the relative difference in temperature performed in each step. Here, the entire temperature protocol using the medical cooling system does not necessarily need to be performed including all the steps shown, and of course, the steps necessary for the individual procedure may be selected. In this case, the cooling method using the medical cooling system may perform the remaining steps while maintaining the relative temperature difference even if some of the performing steps are omitted.

First, the attaching step S-1 will be described with reference to FIG. 5F.

When the operator directly contacts the cooling medium cooled by the medical cooling system directly with the target area of the patient, the contact portion may adhere to the cooling medium due to a sudden temperature difference between the target area and the cooling medium. Attaching step (S-1) according to the present invention is to solve the above problems even when the operator uses a medical cooling system in a state not prepared as described above, the cooling medium is a cooling disinfection step (S-2) It can be controlled to maintain a temperature higher than the temperature at. At this time, the temperature range in the attaching step (S-1) may be -10 ℃ or more. In addition, the temperature range in the attaching step (S-1) may be -5 ° C or more.

On the other hand, the medical cooling system according to another embodiment of the present invention may further include a timer (not shown). As described above, the medical cooling system attaches the cooling medium even if the operator presses the power button for the procedure in order to prevent a problem when the cooled cooling medium is in contact with the target area of the patient when the operator is not ready. After controlling to maintain the step (S-1), after a predetermined time has elapsed by using a timer (not shown) stored in advance (T1) to control to proceed to the cooling disinfection step (S-2) Can be. At this time, the sterilization step (S-2) may be omitted and the process may be directly passed to the cooling anesthesia step (S-3). In other words, the medical cooling system may control the cooling temperature of the cooling medium to be different from the cooling temperature of the cooling medium after driving the timer and the cooling temperature before contacting the target region, which is the treatment site. Alternatively, the medical cooling system may have a temperature different from the temperature in the attaching step (S-1) to the temperature in the cooling disinfection step (S-2) or the temperature in the cooling anesthesia step (S-3). As another embodiment, it is obvious that the medical cooling system can be terminated by user's operation, rather than being terminated after a predetermined time has elapsed.

In this case, the entire temperature protocol using the medical cooling system may have a gradual temperature section Gd having a gentle temperature change slope from the attaching step S-1 to the cooling disinfection step S-2. In other words, the overall temperature protocol induces a gradual gradient of temperature change from the attaching step (S-1) to the cooling disinfection step (S-2), thereby smoothly reaching the final cooling target temperature, thereby allowing the patient to cool the patient in the cooling process. It can minimize the sensation of temperature changes, so that discomfort can be minimized.

Thereafter, the cooling disinfection step (S-2) may be a step of disinfecting the target region at a lower cooling temperature than the attaching step (S-1) using a medical cooling system. Cooling disinfection step (S-2) may be carried out in a temperature range that can kill or reduce the activity of bacteria that may be present on the skin surface of the target area, that is, the treatment site. Cooling method according to one embodiment by applying a third temperature range of less than -2 ℃, for example, a third temperature range of -90 ℃ to -2 ℃ to cool the target area, thereby erasing the bacteria or activity Deterioration can be performed to anesthetize the target area or to disinfect before injecting the chemical solution to the target area. However, the technical spirit of the present invention is not limited thereto, and the third temperature range may be determined in consideration of the sterilizable temperature range existing in the target region. At this time, the cooling disinfection step (S-2) may have a temperature range lower than the lowest temperature in the cooling anesthesia step (S-3). The temperature at the sterilization stage is intended to sterilize bacteria or reduce activity, so the temperature should be lower than the temperature range at which anesthesia is performed.

Thereafter, the cooling anesthesia step (S-3) may be performed by performing cooling on the target area in a preset temperature range. The temperature range in the cooling anesthesia step (S-3) may be a temperature range of more than -2 ℃ higher than 0 ℃ than the temperature range in the cooling disinfection step (S-2).

Next, the detaching step S-42 will be described with reference to FIGS. 5G and 5H.

The detaching step S-42 refers to a step of separating the medical cooling apparatus from the target area after performing the cooling anesthesia step S-3. At this time, the surface of the target region and the cooling medium may be stuck by the cooling. When the medical cooling apparatus is immediately removed, damage may occur on the surface of the target region. In order to prevent such damage, the entire temperature protocol may control the temperature of the cooling medium to be different from the temperature in the cooling anesthesia step (S-3) before separating the cooling medium from the target area. The temperature range in the detaching step S-42 may perform post-cooling above a predetermined temperature. In post-cooling, the temperature may be different from the temperature in the cooling disinfection step S-2 or the temperature in the cooling anesthesia step S-3, specifically, the cooling disinfection step S-2. It may be higher than the temperature at or in the cold anesthesia step (S-3).

Meanwhile, the medical cooling system may further include a notification unit (not shown). The medical cooling system is subjected to a temperature higher than the temperature in the cooling disinfection step (S-2) or the temperature in the cooling anesthesia step (S-3) for post-cooling in the detaching step (S-42). After the rise, the operator may inform the outside using a notification unit (not shown) to immediately remove the cooling medium from the target area. The notification unit (not shown) may provide a notification signal to the outside using various signals such as sound, light, and vibration. The notifying unit (not shown) may provide the above-mentioned notification signal when a predetermined time elapses after the cooling medium reaches a predetermined temperature or more.

On the other hand, the overall temperature protocol may further include a drug anesthesia and disinfection step (S-41) to anesthetize or disinfect using a drug between the cooling anesthesia step (S-3) and the detaching step (S-42). In this case, the detaching step (S-42) may be performed immediately after injecting the medicament. In one embodiment, the temperature range in the drug anesthesia and disinfection step (S-41) may be the same as the temperature range in the detaching step (S-42). In another embodiment, the temperature range in the detaching step (S-42) may be different from the temperature range in the drug anesthesia and disinfection step (S-41), for example, the detaching step (S-42). The temperature range in may have a temperature range lower than that in the drug anesthesia and disinfection step (S-41).

Next, the drying step S-5 will be described with reference to FIG. 5I.

The drying step (S-5) may be a step of removing moisture generated during cooling by maintaining a constant temperature range for a predetermined time after use is completely separated from the target area of the patient. For example, the drying step (S-5) controls the cooling medium to have a temperature range of 20 ° C. or more, thereby drying the moisture generated during cooling by the cooling disinfection step (S-2) or the cooling anesthesia step (S-3). This can increase the pollution prevention and durability of the device. As another embodiment, the drying step (S-5) may be controlled so that the cooling medium has a temperature range of 30 ℃ or more. The medical cooling system may control the operation of the cooling generating unit so that the cooling medium has the above temperature range. Specifically, the temperature of the cooling medium may be controlled by controlling the direction of the current of the thermoelectric element to be opposite to the step of performing cooling. It can be heated quickly to the temperature at which drying takes place.

As described above, the cooling method using the medical cooling system 1 is characterized in that to maintain the temperature within different temperature ranges step by step according to the multi-step. The medical cooling apparatus 10 may maintain the temperature according to the multi-step by controlling the output of the cooling generating unit 113 generating the cooling energy. In this case, the medical cooling apparatus 10 may perform cooling at a high speed below a specific temperature by applying the maximum current or the maximum voltage allowed by the cooling generator 113.

As described above, the present invention has been described with reference to one embodiment shown in the drawings, which is merely exemplary, and it will be understood by those skilled in the art that various modifications and embodiments may be made therefrom. Therefore, the true technical protection scope of the present invention will be defined by the technical spirit of the appended claims.
