Description

Intra-abdominal temperature maintenance system

[0001] The present invention relates to a system for maintaining temperature within an abdominal cavity, and more particularly, to a system for maintaining temperature within an abdominal cavity using an infrared dome to treat cancer, etc. in a patient.

[0002] Cross-reference to related applications

[0003] This application claims priority to Republic of Korea Patent Application No. 10-2024-0050566, filed April 16, 2024, the entire contents of which are incorporated herein by reference.

[0004] If cancer cells have metastasized into the abdominal cavity, the metastasized cancer cells can be suppressed or eliminated through intraperitoneal chemotherapy (IPC), which directly injects drugs into the abdominal cavity; pressurized intraperitoneal aerosol chemotherapy (PIPAC), which directly sprays atomized drugs into the abdominal cavity; or hyperthermic pressurized intraperitoneal aerosol chemotherapy (HPIPAC), which injects drugs into the abdominal cavity and injects heated gas to maintain the temperature within the abdominal cavity.

[0005] HPIPAC can achieve similar cancer cell removal or inhibition efficiencies as other procedures, even with smaller amounts of medication. However, the intraperitoneal temperature must be maintained at approximately 42°C, the temperature at which cancer cells die. However, due to heat loss caused by injecting heated gas into the abdominal cavity and the body's temperature homeostasis (e.g., 36°C), it is difficult to maintain a constant intraperitoneal temperature. Furthermore, if heated gas is injected into the abdominal cavity at a temperature higher than approximately 42°C due to heat loss and body temperature homeostasis, it can cause damage to abdominal organs, such as low-temperature burns, leading to additional side effects. Furthermore, methods of maintaining intraperitoneal temperature by directly contacting the abdominal cavity with means such as an electric blanket require additional disinfection of the surgical site and carry a risk of infection.

[0006] The purpose of the present invention is to provide a temperature maintenance system within the abdominal cavity that can effectively suppress or remove cancer cells within the abdominal cavity.

[0007] In addition, the present invention aims to provide an intraperitoneal temperature maintenance system capable of maintaining the intraperitoneal temperature at a temperature at which cancer cells die.

[0008] In addition, the present invention aims to provide an intra-abdominal temperature maintenance system that can prevent additional side effects of a patient in advance while minimizing the risk of low-temperature burns, etc.

[0009] In addition, the present invention aims to provide an intraperitoneal temperature maintenance system that does not require additional sterilization of the abdominal cavity after removal of cancer cells.

[0039] A temperature maintenance system according to one embodiment of the present invention may be a system for hyperthermic pressurized intraperitoneal chemotherapy (HPIPAC) for the suppression or removal of cancer cells metastasized within the abdominal cavity. For ease of understanding, the following description will exemplify a situation in which the temperature maintenance system according to one embodiment maintains the temperature within the abdominal cavity, where a micronized anticancer drug, etc., has been injected into the abdominal cavity where cancer cells have metastasized.

[0040] Fig. 1 is a perspective view schematically showing a temperature maintenance system according to a first embodiment of the present invention. Fig. 2 is an enlarged cross-sectional view of the infrared dome of Fig. 1 taken along a second direction.

[0041] Hereinafter, a temperature maintenance system according to a first embodiment of the present invention will be described in detail with reference to FIGS. 1 and 2. Hereinafter, the direction in which a patient (P) is lying on a table (T) is defined as a first direction (11), and the direction perpendicular to the first direction (11) when viewed from above is defined as a second direction (12). In addition, a direction perpendicular to a plane including both the first direction (11) and the second direction (12) is defined as a third direction (13). The third direction (13) may be a direction perpendicular to the ground.

[0042] The temperature maintenance system (10) according to the first embodiment may include a heating gas supply unit (100) and a first temperature maintenance unit (200).

[0043] The heated gas supply unit (100) according to the first embodiment injects heated gas into the abdominal cavity through an exposed area (E) formed on the abdomen of a patient (P) using a trocar. Here, the exposed area (E) may be understood as a site opened to suppress or remove cancer cells that have metastasized into the abdominal cavity. The gas according to the first embodiment may be CO2. However, the present invention is not limited thereto, and the gas injected into the abdominal cavity may further include a known gas used for the procedure. The heated gas supply unit (100) according to the first embodiment may be composed of a gas supply source (not shown), a gas supply trocar (not shown), a heating unit for increasing the temperature of the gas flowing inside the trocar, a known valve, and a flow rate controller. In addition, the heated gas supply unit (100) according to the first embodiment may be a circulation system. More specifically, it may be composed of a system that injects heated gas into the abdomen, discharges the gas inside the abdomen from the abdomen, and reheats it. For example, the temperature of the gas injected into the abdominal cavity may be approximately 38°C to 42°C.

[0044] The first temperature maintenance unit (200) according to the first embodiment can maintain the temperature of a patient (P) lying on a table. More specifically, the first temperature maintenance unit (200) can directly transmit a first heat source (HS1) into the abdominal cavity through an exposed area (E) on the abdomen of the patient (P), thereby maintaining the temperature within the abdominal cavity at a constant temperature. The first heat source (HS1) according to the first embodiment can be infrared rays. For example, the first heat source (HS1) can be near infrared rays having a wavelength range of approximately 700 nm to 1,400 nm. The constant temperature can be 38°C to 42°C. Preferably, the first temperature maintenance unit (200) can maintain the temperature within the abdominal cavity at 42°C.

[0045] The first temperature maintenance unit (200) according to the first embodiment may include a dome housing (210), a first heat source irradiation unit (220), a first power source unit (230), and a first control unit (240).

[0046] The dome housing (210) has a dome shape. More specifically, the dome housing (210) may have a hemispherical cross-section. The dome housing (210) may have a shape in which the front and the back are open. In addition, the dome housing (210) has a heated space (S) surrounded by an inner surface therein. The dome housing (210) is placed on a table (T). When viewed from above, the dome housing (210) is placed so as to overlap the abdomen of a patient (P) lying on the table (T). For example, the dome housing (210) may be placed so as to wrap from the abdomen of the patient (P) to around the shoulder of the patient (P). Preferably, the dome housing (210) is placed so as to overlap the exposed area (E) of the patient (P) when viewed from above. However, at this time, the dome housing (210) is placed at a certain distance from the patient (P) so as not to come into contact with the body of the patient (P). That is, both the dome housing (210) and the first heat source irradiation unit (220) described later are not in contact with the patient (P) and the exposed area (E) formed on the abdomen of the patient (P), respectively.

[0047] For example, the dome housing (210) may have a structure in which one side is fixed on the table (T) in a hinged manner or the like, and the other side can be freely opened. In this case, the dome housing (210) is configured to cover the outside of the abdomen of a patient (P) lying on the table (T). However, the present invention is not limited to the above-described example, and the dome housing (210) may have a structure in which it is not fixed on the table (T). In this case, the dome housing (210) may be placed by an operator at a position overlapping the exposed area (E) of the patient (P) lying on the table (T).

[0048] The first heat source irradiation unit (220) irradiates the first heat source (HS1) to the heated space (S). The first heat source irradiation unit (220) is formed in the dome housing (210). More specifically, the first heat source irradiation unit (220) is formed on the inner surface of the dome housing (210). A plurality of first heat source irradiation units (220) may be provided. The plurality of first heat source irradiation units (220) may be formed along the circumferential direction of the inner surface of the dome housing (210). In addition, the plurality of first heat source irradiation units (220) formed along the circumferential direction of the dome housing (210) may be arranged in a plurality of rows. The plurality of first heat source irradiation units (220) may be arranged to be spaced apart from each other by a certain interval. In addition, each of the first heat source irradiation units (220) according to the first embodiment may be formed to be inclined in a direction toward the exposed portion (E).

[0049] As described above, the dome housing (210) is arranged to overlap the exposed area (E) of the patient (P) when viewed from above. Accordingly, the first heat source (HS1) irradiated onto the heated space (S) is directly transmitted to the exposed area (E) located within the heated space (S). By the first heat source (HS1) directly transmitted to the exposed area (E), the temperature inside the abdominal cavity of the patient (P) can be increased or maintained at a constant temperature. For example, the temperature loss of the heated gas supplied from the heating gas supply unit (100) can be compensated for by the first heat source (HS1) transmitted to the exposed area (E). That is, even if the temperature of the heated gas supplied inside the abdominal cavity decreases after a predetermined period of time, the first heat source (HS1) directly transmitted to the exposed area (E) can increase the temperature inside the abdominal cavity, which has decreased, to 42°C again. Additionally, the first heat source (HS1) can be continuously delivered to the exposed area (E) so that the temperature inside the abdominal cavity is maintained at 42°C.

[0050] The first power supply unit (230) supplies power so that the first heat source irradiation unit (220) can irradiate the first heat source (HS1) into the heated space (S). The first control unit (240) controls the temperature of the heated space (S). More specifically, the first control unit (240) controls the first heat source irradiation unit (220) to control the temperature of the heated space (S). The first control unit (240) can control the temperature of the heated space (S) by controlling the irradiation amount of the first heat source (HS1) irradiated from the first heat source irradiation unit (220).

[0051] According to the first embodiment, the first control unit (240) controls the first heat source irradiation unit (220) so that the temperature of the heated space (S) is maintained at a temperature of 70°C or lower. Preferably, the first control unit (240) controls the first heat source irradiation unit (220) so that the temperature of the heated space (S) is adjusted to a temperature of 42°C to 70°C or lower.

[0052] The first control unit (240) can irradiate the first heat source (HS1) provided at a temperature relatively higher than 42°C, which is the temperature of the gas injected into the abdominal cavity by the heating gas supply unit (100), into the heated space (S). Accordingly, the temperature inside the abdominal cavity, which has decreased due to heat loss inside the abdominal cavity, can be raised again to maintain it at an appropriate temperature (e.g., 42°C) at which cancer cells are killed.

[0053] The first control unit (240) according to the first embodiment may be configured with a process controller formed of a microprocessor (computer) that executes control of the first heat source irradiation unit (220), a user interface formed of a keyboard through which an operator performs command input operations to manage the device, a display panel that visually displays the operating status of the device, and a control program for executing the device under the control of the process controller, and a memory unit for storing such a program. Accordingly, the first control unit (240) according to the first embodiment can remotely control the irradiation amount of the first heat source (HS1) irradiated from the first heat source irradiation unit (220) by wireless connection. However, the present invention is not limited thereto, and may be provided in the form of an electronic panel on the outer surface of the dome housing (210) to control the irradiation amount of the first heat source (HS1) in a touch manner.

[0054] As mentioned above, during and / or after intraperitoneal injection of anticancer drugs or other drugs to eliminate intraperitoneal cancer cells, heated gas is injected into the intraperitoneal cavity to more effectively kill the cancer cells. However, the temperature of the gas injected into the intraperitoneal cavity can be lowered for various reasons, reducing the effectiveness of removing metastatic cancer cells within the intraperitoneal cavity.

[0055] According to the first embodiment described above, by irradiating the exposure area (E) with infrared rays, an example of a first heat source (HS1), the temperature within the abdominal cavity can be raised or maintained at a temperature that maximizes the efficiency of cell removal. Accordingly, the efficiency of suppressing or removing metastatic cancer cells within the abdominal cavity can be dramatically increased.

[0056] Furthermore, the first embodiment described above maintains intra-abdominal temperature without contact with the patient (P), eliminating the need for additional post-operative disinfection of the surgical site or surgical instruments. This enhances the efficiency and convenience of the procedure and reduces the risk of additional infection for the patient due to disinfection issues.

[0057] In addition, according to the first embodiment described above, since the dome housing (210) is provided in a dome shape and the first heat source irradiation unit (220) directly irradiates the heat source toward the exposed area (E), the efficiency of heat transfer into the abdominal cavity increases dramatically. Accordingly, the temperature inside the abdominal cavity of the patient can be quickly increased even at a relatively low temperature, and the heat escaping to the outside can be minimized due to the dome shape. In addition, since the temperature inside the abdominal cavity can be increased even at a low temperature, the risk of low-temperature burns of the patient can be minimized.

[0058] Below, a temperature maintenance system according to a second embodiment of the present invention will be described in detail. The temperature maintenance system described below has, except where additional details are provided, a structure and function largely identical or similar to those of the temperature maintenance system described with reference to FIGS. 1 and 2. Therefore, any overlapping details will be omitted.

[0059] Fig. 3 is a perspective view schematically showing a temperature maintenance system according to a second embodiment of the present invention. Fig. 4 is an enlarged cross-sectional view of the infrared dome of Fig. 3 taken along the first direction. In Figs. 3 and 4, the heating gas supply unit (100), the first power supply unit (230), and the first control unit (240) illustrated in Fig. 1 are omitted for ease of understanding.

[0060] Referring to FIGS. 3 and 4, the temperature maintenance system (10) according to the second embodiment further includes an air supply unit (300).

[0061] The air supply unit (300) supplies air (A). The air supply unit (300) supplies air (A) toward a patient (P) lying on a table (T). More specifically, the air supply unit (300) supplies air (A) so as to block the first heat source (HS1) emitted from the first temperature maintenance unit (200) from being emitted from the exposed area (E) of the patient (P).

[0062] The air supply unit (300) according to the second embodiment may include an air supply source (310), a body (320), an air discharge hole (330), an air supply line (340), an air temperature control unit (350), and an air control unit (360).

[0063] An air supply source (310) supplies air (A). The air supply source (310) may be provided by a known device, such as a known pump or compressor. That is, the air supply source (310) may suck in surrounding air, compress it, and supply it to the air discharge hole (330) through the air supply line (340).

[0064] The body (320) can be placed on the table (T) on which the patient (P) is lying. That is, the body (320) can be placed on the upper side of the table (T). The body (320) can be placed to overlap the dome housing (210) when viewed from above. The body (320) according to the second embodiment can be a mattress. That is, the body (320) can be an air mattress with a cushioned feel. The shape of the body (320) can be formed to generally correspond to the shape of the upper part of the table (T). In FIG. 3, the body (320) is illustrated as supporting only the back of the patient (P), but is not limited thereto. For example, the body (320) can be provided to wrap the entire body of the patient (P) (excluding the head), from the legs of the patient (P) to the vicinity of the shoulders, and including the front and back of the patient (P). In this case, the body (320) can wrap around the outside of the dome housing (210). However, in this embodiment, for the sake of convenience of understanding, an example is given in which the body (320) supports only the back of the patient (P).

[0065] An air discharge hole (330) is formed in the body (320). The air discharge hole (330) is formed on one surface of the body (320) facing the patient (P). According to the second embodiment, the air discharge hole (330) may be formed on the upper surface of the body (320). A plurality of air discharge holes (330) are formed in the body (320). The plurality of air discharge holes (330) are arranged at a constant distance from each other over the entire area of ​​the upper surface of the body (320). The plurality of air discharge holes (330) are each connected to an air supply line (340). In addition, one end of the air supply line (340) is connected to the air supply source (310) described above.

[0066] The air temperature control unit (350) controls the temperature of air (A) flowing within the air supply line (340). The air temperature control unit (350) can increase the temperature of air (A) supplied from the air supply source (310). For example, the air temperature control unit (350) can increase the temperature of air (A) to 40°C to 50°C. Preferably, the air temperature control unit (350) can increase the temperature of air (A) to 45°C.

[0067] The air control unit (360) can control the air supply source (310) and / or the air temperature control unit (350). The air control unit (360) can control the air supply source (310) to adjust the supply amount of air (A) supplied to the air discharge hole (330). In addition, the air control unit (360) can control the air temperature control unit (350) to adjust the temperature of the air (A) in the air supply line (340). Since the configuration and functions included in the air control unit (360) are mostly the same or similar to those of the first control unit described above, a description thereof will be omitted.

[0068] The air supplied from the air supply source (310) is supplied to each of the air discharge holes (330) through the air supply line (340). The air supplied to the air discharge hole (330) is delivered in a direction toward the patient (P). More specifically, as illustrated in FIG. 4, the air (A) is discharged from the air discharge hole (330) in the direction toward the patient, i.e., in the third direction (13). The discharged air (A) blocks the first heat sources (HS1) previously irradiated within the heated space (S) from being discharged to the outside of the heated space (S). In other words, the discharged air (A) functions as a so-called air curtain. Accordingly, the air (A) discharged from the air discharge hole (330) minimizes the atmosphere within the heated space (S) from being discharged to the outside of the heated space (S), thereby maintaining the temperature within the heated space (S). That is, the discharged air (A) acts as an air curtain at the open front and back of the dome housing (210), so that the atmosphere inside the heated space (S) is not immediately released outside the heated space (S), but rather forms a vortex inside the heated space (S). Accordingly, the first heat source (HS1) is effectively delivered to the exposed area of ​​the patient located inside the heated space (S). In conclusion, the temperature inside the abdominal cavity of the patient can be efficiently maintained at a temperature at which cancer cells are maximally killed. In addition, according to the second embodiment, since air heated to a predetermined temperature by the air control unit (360) is discharged, the temperature loss of the heated space (S) due to heat exchange between the atmosphere inside the heated space (S) and the air (A) can be minimized.

[0069] Unlike the second embodiment described above, the air supply unit (300) may not include an air temperature control unit (350). In this case, the air supply unit (300) may focus on blocking the heated atmosphere within the heated space (S) from being released to the outside by supplying air (A) by only controlling the supply amount of air (A) without supplying temperature-controlled air (A).

[0070] Fig. 5 is a perspective view schematically showing a temperature maintenance system according to a third embodiment of the present invention. In Fig. 5, for the sake of convenience of understanding, the illustrations of the heating gas supply unit (100), the first power supply unit (230), and the first control unit (240) illustrated in Fig. 1, as well as the illustrations of the air supply source (310), the air temperature control unit (350), and the air control unit (360) illustrated in Fig. 3, are omitted.

[0071] Referring to Fig. 5, the air discharge holes (330) according to the third embodiment can be formed in a concentrated manner in a specific area. More specifically, the air discharge holes (330) can be formed densely in an area overlapping the dome housing (210) when viewed from above. According to this embodiment, the atmosphere of the heated space inside the dome housing (210) can be more efficiently blocked from being released to the outside of the heated space due to the air discharged from the air discharge holes (330).

[0072] Fig. 6 is a perspective view schematically showing a temperature maintenance system according to a fourth embodiment of the present invention. In Fig. 6, as in Fig. 5, the heating gas supply unit (100) illustrated in Fig. 1 and the air supply source (310) illustrated in Fig. 3 are omitted.

[0073] Referring to FIG. 6, the temperature maintenance system according to the fourth embodiment may further include a second temperature maintenance unit (400).

[0074] The second temperature maintenance unit (400) can deliver a second heat source to the exposed area (E) of the patient (P). More specifically, the second temperature maintenance unit (400) delivers the second heat source to the back area of ​​the patient (P), thereby indirectly delivering the second heat source to the exposed area.

[0075] The second temperature maintenance unit (400) according to the fourth embodiment may include a second heat source pad (410), a second power source unit (420), and a second control unit (430).

[0076] The second heat source pad (410) may have a generally rectangular shape when viewed from above. In addition, the second heat source pad (410) may be made of a flexible material. In addition, the second heat source pad (410) may be located on the upper side of the body (320) of the table (T) and the air supply unit (300) described above. In addition, the upper surface of the second heat source pad (410) may be in contact with the back of the patient (P). In addition, the second heat source pad (410) may be positioned at a position overlapping the dome housing (210) when viewed from above. That is, the second heat source pad (410) may be positioned to overlap the exposed portion (E) when viewed from above. A heating element that generates heat by resisting a flowing current may be provided inside the second heat source pad (410).

[0077] The second power source (420) applies voltage to the second heat source pad (410) so that current flows. When the second power source (420) applies voltage, a heating element provided inside the second heat source pad (410) resists the flowing current to generate resistive heat (hereinafter, referred to as the second heat source). The second heat source is transmitted to the patient. More specifically, the second heat source is directly transmitted to the back of the patient (P) in contact with the upper surface of the second heat source pad (410), and indirectly transmitted to the exposed area (E) formed on the abdomen of the patient (P). In conclusion, the second heat source indirectly transmitted to the exposed area (E) raises and / or maintains the temperature of the exposed area (E).

[0078] The second control unit (430) controls the second power unit (420). The second control unit (430) controls the resistance heat generated in the second heat source pad (410) by adjusting the voltage applied to the second power unit (420). For example, the second control unit (430) can control the temperature of the second heat source to 40°C to 50°C. Since the components included in the second control unit (430) or their functions are mostly the same or similar to those of the first control unit described above, a description thereof will be omitted.

[0079] According to the present embodiment, in addition to the first temperature maintenance unit and the air supply unit, an additional heat source is delivered to the exposed area (E) by the second temperature maintenance unit (400), so that the temperature within the abdominal cavity of the patient (P) can be more efficiently increased and / or maintained at a temperature at which cancer cells can be maximally killed. In addition, since the second temperature maintenance unit (400), like the first temperature maintenance unit and the air supply unit, delivers a heat source to the exposed area (E) in a non-contact manner, the effect of the heat source delivery by non-contact is as described above.

[0080] Unlike the embodiments described above, the first temperature maintenance unit (200), the air supply unit (300), and the second temperature maintenance unit (400) can be provided independently, and of course, can be provided in combination with each other in various combinations.

[0081] FIG. 7 is an enlarged cross-sectional view of an infrared dome of a temperature maintenance system according to a fifth embodiment of the present invention, cut along the second direction.

[0082] Referring to FIG. 7, the first heat source irradiation unit (220) according to one embodiment may include a far-infrared irradiation unit (222) and a near-infrared irradiation unit (224). The far-infrared irradiation units (222) and the near-infrared irradiation units (224) may be provided in multiple numbers along the inner circumferential direction of the dome housing (210). In addition, the far-infrared irradiation units (222) and the near-infrared irradiation units (224) may be arranged in multiple rows. In addition, the far-infrared irradiation units (222) and the near-infrared irradiation units (224) may be arranged at a constant interval from each other. In addition, the far-infrared irradiation units (222) and the near-infrared irradiation units (224) may be arranged to be inclined in the direction toward the exposure portion (E), respectively. For example, the far-infrared irradiation unit (222) and the near-infrared irradiation unit (224) can be arranged alternately.

[0083] In one embodiment, a far-infrared ray irradiation unit (222) irradiates a first heat source (HS1-1) into a heated space (S). In one embodiment, the first heat source (HS1-1) may be far-infrared. The far-infrared ray irradiation unit (222) irradiates the first heat source (HS1-1) into the heated space (S) to increase the temperature of the heated space (S). A near-infrared ray irradiation unit (224) in one embodiment irradiates a first-second heat source (HS1-2) into the heated space (S). In one embodiment, the first-second heat source (HS1-2) may be near-infrared. Since near-infrared has relatively better penetration into body tissues than far-infrared, the irradiated first-second heat source (HS1-2) can be irradiated relatively more directly to a patient (P) located within the heated space (S) than the first-first heat source (HS1-1). That is, the temperature of the exposed area (E) of the patient (P) can be maintained or the temperature of the exposed area (E) of the patient (P) can be indirectly increased depending on the atmosphere of the heated space (S) whose temperature is increased by the first-first heat source (HS1-1), and the temperature of the exposed area (E) of the patient (P) can be directly increased by the first-second heat source (HS1-2). Therefore, the temperature of the exposed area can be more efficiently controlled, maintained at the temperature required for the exposed area, and heat loss from the exposed area can be minimized.

[0084] It goes without saying that the far-infrared irradiation unit (222) and the near-infrared irradiation unit (224) can have their irradiation amounts controlled by separately provided control units (not shown) like the first control unit (240) described above. In this embodiment, as in the above-described embodiment, each temperature maintenance unit and air supply unit can be provided independently, and can be provided in various combinations.

[0085] The detailed description above is illustrative of the present invention. Furthermore, the above description illustrates and describes preferred embodiments of the present invention, and the present invention can be used in various other combinations, modifications, and environments. In other words, changes or modifications are possible within the scope of the inventive concept disclosed in this specification, the scope equivalent to the written disclosure, and / or the scope of technology or knowledge in the art. The written embodiments illustrate the best possible state for implementing the technical idea of ​​the present invention, and various modifications required for specific application fields and uses of the present invention are also possible. Therefore, the detailed description of the invention above is not intended to limit the present invention to the disclosed embodiments. Furthermore, the appended claims should be construed to include other embodiments.

[0086] According to the intra-abdominal temperature maintenance system according to embodiments of the present invention, the temperature within the abdominal cavity can be maintained at a temperature at which cancer cells can be killed in a non-contact manner, thereby efficiently removing cancer cells within the abdominal cavity.
