[0002] Intracavitary hyperthermic perfusion (ICP-P) devices are therapeutic devices that eliminate tumor cells by infusing a perfusion fluid heated to supraphysiological levels into the body cavity. They can be used alone or in combination with radiotherapy and chemotherapy. ICP-P utilizes the diffusivity, conductivity, and physical flushing properties of water to address the challenges of diffuse tumor lesions that surgery and radiotherapy cannot resolve, effectively preventing tumor metastasis and reducing the production of malignant effusions.

[0003] Traditional intraperitoneal hyperthermic perfusion therapy equipment has difficulty controlling the temperature and flow rate of the perfusion fluid. After being perfused into the patient's abdominal cavity, the effect is limited and it is easy to cause other complications. Utility Model Content

[0019] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments, and the operational steps involved in each embodiment can also be rearranged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for clearly describing a particular embodiment and do not imply that they represent the necessary components and / or order.

[0020] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0021] See Figures 1-7 As shown, the intracavitary thermal infusion device provided in this application includes a housing 10, a heating device 20, a pre-infusion temperature sensor 24, an infusion device 30, and a thermal management module 40.

[0022] The housing 10 is the main structure of the body cavity hot infusion device and can be used to install other devices or modules. A base 15 is also provided at the bottom of the housing 10, and four rectangular array casters 16 are provided at the bottom of the base 15. The body cavity hot infusion device can be moved by pushing the casters 16 to facilitate the use of this product. The casters 16 have a locking structure, which can lock the casters 16 after the device has been moved into place.

[0023] The heating device 20 includes a heating component 21 and a heating temperature sensor 22. The heating component 21 is disposed in the housing 10 and can employ one of the following heating methods: electromagnetic induction heating, resistance heating, or infrared heating. In this embodiment, the heating component 21 uses electromagnetic induction heating. The heating component 21 has a heating position 211 for placing a collection tank 212 for storing perfusion fluid. The perfusion fluid is a liquid injected into the patient's body cavity to treat cancerous effusion and metastatic cancer within the body cavity, achieving a cancer cell killing effect. The heating temperature sensor 22 is electrically connected to the heating component 21 and is used to detect the heating temperature of the perfusion fluid in the collection tank 212. The heating component 21 heats the perfusion fluid in the collection tank 212 placed in the heating position 211, ensuring that the temperature of the perfusion fluid reaches a preset temperature that meets the requirements for perfusion into the human body cavity.

[0024] In this embodiment, after the heating temperature sensor 22 detects that the filling liquid in the liquid collection tank 212 has been heated to a preset temperature, it can control the heating component 21 to adjust the heating power in real time for heat preservation.

[0025] A pre-fill temperature sensor 24 is installed on the housing 10. The filling liquid in the collection tank 212 can be added by filling so that the filling liquid can be used continuously. The pre-fill temperature sensor 24 is used to detect the temperature of the filling liquid before it is added to the collection tank 212.

[0026] The infusion device 30 includes a circulation pump 31, an infusion temperature sensor 32, and a flow sensor 33. The circulation pump 31 is connected to the collection tank 212 and is used to pump the infusion fluid in the collection tank 212. Specifically, the circulation pump 31 pumps the infusion fluid heated to a preset temperature in the collection tank 212 to the human body cavity through the hot infusion treatment tubing 311. The infusion temperature sensor 32 is used to detect the temperature of the infusion fluid pumped by the circulation pump 31. Since the infusion fluid experiences some temperature loss during pumping in the hot infusion treatment tubing 311, the temperature of the infusion fluid during pumping is detected by the infusion temperature sensor 32.

[0027] Flow sensor 33 is connected to circulating pump 31. Flow sensor 33 is used to detect the flow rate of the infusion fluid pumped by circulating pump 31 to ensure that the flow rate of the infusion fluid pumped by circulating pump 31 meets the preset flow rate and avoids the infusion fluid flow rate being too high or too low. When flow sensor 33 detects that the flow rate of the infusion fluid pumped by circulating pump 31 is less than or greater than the preset flow rate, the output power of circulating pump 31 can be adjusted in a timely manner. For example, when flow sensor 33 detects that the flow rate of the infusion fluid pumped by circulating pump 31 is less than the preset flow rate, the output power of circulating pump 31 is increased to increase the flow rate to the preset flow rate. When flow sensor 33 detects that the flow rate of the infusion fluid pumped by circulating pump 31 is greater than the preset flow rate, the output power of circulating pump 31 is decreased to reduce the flow rate to the preset flow rate.

[0028] In one embodiment, the hot perfusion therapy line 311 is controlled to open and close by a solenoid valve 35, which is controlled by a solenoid valve control board 351.

[0029] The thermal management module 40 is installed inside the housing 10 and is electrically connected to the heating temperature sensor 22, the pre-entry temperature sensor 24, the inlet temperature sensor 32, and the heating component 21. In practical use, the pre-fill temperature sensor 24 detects the temperature of the filling liquid added to the collection tank 212 and transmits this temperature information to the thermal management module 40. The heating temperature sensor 22 detects the temperature of the filling liquid in the collection tank 212 placed on the heating position 211 of the heating component 21 and transmits this temperature information to the thermal management module 40. The body temperature sensor 32 detects the temperature of the filling liquid pumped into the body cavity by the circulation pump 31 in the collection tank 212 and transmits this temperature information to the thermal management module 40. The thermal management module 40 can control the heating temperature of the heating component 21 according to the temperature of the filling liquid added to the collection tank 212 detected by the pre-fill temperature sensor 24. At the same time, when the heating temperature sensor 22 detects that the temperature of the filling liquid in the collection tank 212 reaches the preset temperature, it controls the heating component 21 to adjust the power to maintain the temperature. Alternatively, when the heating temperature sensor 22 detects that the temperature of the filling liquid in the collection tank 212 is greater than or less than the preset temperature, it adjusts the heating component 21 to reduce or increase the heating power. The thermal management module 40 can also adjust the heating power of the heating component 21 in real time according to the temperature of the infusion fluid detected by the infusion temperature sensor 32, so as to further ensure that the infusion fluid can reach the preset temperature.

[0030] In this embodiment, the heating component 21 heats the perfusion fluid in the collection tank 212 placed in the heating position 211, while the heating temperature sensor 22 detects the temperature of the perfusion fluid in the collection tank 212. The heating temperature of the heating component 21 is adjusted in a timely manner based on the temperature of the perfusion fluid detected by the thermal management module 40 and the heating temperature sensor 22 until the temperature of the perfusion fluid detected by the heating temperature sensor 22 reaches the preset temperature. During this process, the thermal management module 40 can also adjust the heating temperature of the heating component 21 according to the temperature of the perfusion fluid added to the collection tank 212 detected by the pre-entry temperature sensor 24 and the in-body temperature sensor 32, as well as the temperature of the perfusion fluid pumped into the body cavity, to further ensure that the perfusion fluid reaches the preset temperature. Simultaneously, the flow rate of the perfusion fluid pumped by the circulation pump 31 is detected by the flow sensor 33 to ensure that the flow rate reaches the preset flow rate, thereby achieving precise control of the perfusion fluid temperature and flow rate and improving the therapeutic effect of the perfusion fluid.

[0031] After the perfusion fluid is pumped into the body cavity by the circulation pump 31 through the hot perfusion treatment tubing 311, it can also be discharged from the body cavity through the outlet tubing. The temperature of the discharged perfusion fluid needs to be monitored to avoid the risk of abnormal body temperature. If the temperature of the discharged perfusion fluid is too high, it may cause damage to the patient's body cavity tissues or systemic hyperthermia. If the temperature of the discharged perfusion fluid is too low, the therapeutic effect will not be achieved, and it may also cause chills or hypothermia in the patient. Therefore, in this embodiment, the perfusion device 30 also includes an outlet temperature sensor 34, which is electrically connected to the thermal management module 40. The outlet temperature sensor 34 is used to detect the temperature of the perfusion fluid discharged from the body.

[0032] When the body temperature sensor 34 detects that the temperature of the infusion fluid discharged from the human body is lower or higher than the preset discharge temperature, it outputs the temperature information to the thermal management module 40, which then adjusts the heating temperature of the heating component 21.

[0033] In this embodiment, the housing 10 is provided with a pre-entry temperature sensor port 11, an inlet temperature sensor port 12, an outlet temperature sensor port 13, and a heating temperature sensor port 14, which can be used to connect the pre-entry temperature sensor 24, the inlet temperature sensor 32, the outlet temperature sensor 34, and the heating temperature sensor 22, respectively. Figure 6 As shown, a temperature transmitter 41 is also provided between the pre-entry temperature sensor 24, the inlet temperature sensor 32, the outlet temperature sensor 34, and the heating temperature sensor 22 and the thermal management module 40. The temperature transmitter 41 is used to convert the temperature detected by the pre-entry temperature sensor 24, the inlet temperature sensor 32, the outlet temperature sensor 34, and the heating temperature sensor 22 into an electrical signal and transmit it to the thermal management module 40.

[0034] The intracavitary hyperthermic perfusion therapy device provided in this embodiment also includes a temperature and humidity sensor 90 installed on the housing 10. The temperature and humidity sensor 90 is electrically connected to the thermal management module 40. The temperature and humidity sensor 90 is used to detect the ambient temperature and humidity to reflect the ambient temperature and humidity. The thermal management module 40 can adjust the heating temperature of the heating component in real time through the ambient temperature and humidity information. Therefore, by detecting the ambient temperature and humidity, the thermal management module 40 can better regulate the heating temperature of the heating component 21.

[0035] During operation, the equipment generates a large amount of heat, which affects its normal operation. To address this, the intracavitary hyperthermic perfusion therapy device provided in this embodiment also includes a cooling fan 100. The cooling fan 100 is located inside the housing 10. Air inlets 101 and air outlets 102 are provided on opposite sides of the housing 10. The cooling fan 100 is used to introduce external air into the housing 10 through the air inlet 101 and exhaust the air inside the housing 10 through the air outlet 102, so that the external air circulates inside the housing 10 to cool the electrical equipment inside the housing 10.

[0036] A rear cover 17 connected to the housing 10 is provided on the rear side of the body cavity hyperthermic perfusion therapy device. The air inlet 101 and the air outlet 102 are both provided on the rear cover 17, and the cooling fan 100 is installed inside the rear cover 17. The cooling fan 100 makes the air flow in the direction from the air inlet 101 to the air outlet 102 so as to exchange heat with the relay 352 and other electronic devices inside the housing 10.

[0037] In this application, the infusion device 30 also includes a flow control module 36. The flow control module 36 is electrically connected to the flow sensor 33 and the circulating pump 31. The flow information detected by the flow sensor 33 is transmitted to the flow control module 36. The flow control module 36 controls the circulating pump 31 to adjust the output power according to the detected flow information, thereby ensuring that the flow rate of the infusion fluid pumped by the circulating pump 31 can reach the preset flow rate.

[0038] In one embodiment, the intracavitary hyperthermic infusion device further includes a display input module 50 mounted on the housing 10. The display input module 50 is electrically connected to the flow control module 36 and is used to input control information to the flow control module 36.

[0039] The display input module 50 includes a touch screen 51, a display driver board 52, a button circuit board 54, and a display adapter board 53. The display driver board 52 and the button circuit board 54 are both electrically connected to the touch screen 51. The display driver board 52 is electrically connected to the flow control module 36 via the display adapter board 53. The touch screen 51 enables human-computer interaction, allowing the transmission of set flow information to the flow control board. The display driver board 52 is fixed inside the rear cover 17 of the touch screen 51. By connecting to the touch screen 51, it enables human-computer interaction, transmitting set parameter information to the flow control module 36 for overall power and flow control. The button circuit board 54 is fixed inside the lower part of the front of the touch screen 51's housing. The button circuit board 54 controls the functions of the touch screen 51 during human-computer interaction. The display adapter board 53 is fixed inside the lower part of the rear cover 17 of the touch screen 51. It receives flow signals through human-computer interaction, processes them, and then transmits them to the flow control module 36.

[0040] In one embodiment, the flow control board is connected to the display adapter board 53. The display adapter board 53 is used to transmit signals between the flow control board and the display driver board 52, and to transmit the processed signals to the other party, so that the display adapter board 53 acts as a "signal relay station" between the flow control board and the display driver board 52.

[0041] In this embodiment, the heating device 20 further includes a heating control module 23. The input terminal of the heating control module 23 is electrically connected to the thermal management module 40, and the output terminal of the heating control module 23 is electrically connected to the heating component 21. The heating control module 23 controls the start and stop of the heating component 21 and the adjustment of the heating power through the thermal management module 40. Specifically, after the heating temperature sensor 22 detects the temperature of the filling liquid in the liquid collection tank 212 placed in the heating position 211 of the heating component 21, it transmits the detected temperature value to the thermal management module 40 through the heating control module 23. When the detected temperature reaches the preset temperature, the heating component 21 is controlled to stop working. When the detected temperature is less than or greater than the preset temperature, the heating component 21 is adjusted to increase or decrease the heating power.

[0042] In this application, after the perfusion fluid in the collection tank 212 is pumped into the human body cavity by the circulation pump 31, it is necessary to replenish the collection tank 212 with perfusion fluid. In this regard, the body cavity thermal perfusion therapy device provided in this embodiment also includes a collection bag collection mechanism 60. The collection bag collection mechanism 60 is disposed on the housing 10 and is used to collect the collection bag, which can add perfusion fluid to the collection tank 212.

[0043] The liquid collection bag collection mechanism 60 is a box structure, and a first hook 61 is provided inside it. The first hook 61 is used to hang the liquid collection bag, which is convenient for storing the liquid collection bag in the liquid collection bag collection mechanism 60.

[0044] In one embodiment, the liquid collection bag collection mechanism 60 further includes a second hook 62, which is disposed on the top of the housing 10. A crossbeam is disposed on the top of the housing 10, and a plurality of second hooks 62 are disposed on the crossbeam to facilitate the hanging of a plurality of liquid collection bags.

[0045] The perfusion fluid in the collection tank 212 is pumped to the human body cavity by the circulation pump 31. There is a certain amount of air in the collection tank 212, which needs to be expelled. To address this, the body cavity thermal perfusion therapy device provided in this embodiment also includes a waste liquid collection mechanism 70 installed on the housing 10. The waste liquid collection mechanism 70 is connected to the collection tank 212 and is used to collect the air and perfusion fluid that are expelled when the perfusion fluid is added to the collection tank 212. The perfusion fluid is a small portion of the perfusion fluid that is carried in during the air expulsion process.

[0046] like Figure 1 As shown, the intracavitary hyperthermic perfusion therapy device provided in this embodiment also includes a switch assembly 80, which is disposed in the housing 10. The switch assembly 80 is used to electrically connect the external power supply 812 to the heating device 20, the perfusion device 30 and the thermal management module 40.

[0047] In this embodiment, the switch assembly 80 includes an emergency stop switch 82, a start button 83, and a power off button 84. The emergency stop switch 82 is used to immediately stop the equipment from working in an emergency or when the equipment malfunctions, so as to prevent accidents from happening. The start button 83 is used to start the equipment, and the power off button 84 is used to turn off the equipment.

[0048] In one embodiment, the start button 83 is also connected to a filter 81, which filters out specific frequency points in the power supply 812.

[0049] In this application, combined with Figure 7As shown, the emergency stop switch 82 is followed by an AC circuit breaker 85, which is used to cut off the power supply in time when the current in the circuit is too high to protect the equipment. The AC circuit breaker 85 is connected to the start button 83 and the stop button 84, which supply power to the subsequent electronic components. The AC circuit breaker 85 is connected to the heating control module 23. After the AC circuit breaker 85 is turned on, it supplies power to the heating control module 23, the 24V switching power supply 88, and the 12V switching power supply 89. The 24V switching power supply 88 provides 24V DC power to the thermal management module 40 and the solenoid valve control board 351, while the 12V switching power supply 89 provides 12V DC power to the flow control module 36. The relay 352 is connected between the thermal management module 40 and the heating component 21. The heating component 21 is controlled by the heating control module 23. The thermal management module 40, through its connection with the temperature and humidity sensor 90, adjusts the power of the heating component 21 after collecting the ambient temperature and humidity signals, achieving more precise power regulation.

[0050] In this embodiment, temperature transmitters 41 are respectively installed between the thermal management module 40 and the pre-entry temperature sensor 24, the inlet temperature sensor 32, the outlet temperature sensor 34, and the heating temperature sensor 22.

[0051] Combination Figure 5 and Figure 7 As shown, the display driver board 52 is also connected to a first interface 55, a second interface 56, and a second interface 57. The first interface 55 is a USB interface for connecting a USB flash drive or printer. The second interface 56 is a WiFi interface for connecting a WiFi receiver to receive wireless networks. The second interface 57 is an RJ45 interface for connecting a network cable to receive networks via a wired connection.

[0052] like Figure 7 As shown, a speaker 87 is also provided inside the housing 10. The speaker 87 can play the temperature information of the injection fluid detected by the heating temperature sensor 22, and can also play the flow information of the injection fluid detected by the flow sensor 33.

[0053] The usage process of the intracavitary hyperthermic perfusion device provided in this application is as follows: Before powering on, check the power supply 812 to ensure the voltage is within its effective output range, and that the power socket 811 and grounding connection are good. Check that the emergency switch is reset and that all parts of the equipment are secure. Move the equipment to a suitable location and lock the casters 16. Insert the pre-entry temperature sensor 24, in-body temperature sensor 32, out-of-body temperature sensor 34, and heating temperature sensor 22 into the pre-entry temperature sensor socket 11, in-body temperature sensor socket 12, out-of-body temperature sensor socket 13, and heating temperature sensor socket 14, respectively. Assemble the hot perfusion treatment tubing 311 with the circulation pump 31. Pump the perfusion fluid into the hot perfusion treatment tubing 311 through the circulation pump 31 to purge the air from the tubing.

[0054] Plug the power cord into the power socket 811, turn on the filter 81, and the power supply from the power supply 812 is transmitted to the AC circuit breaker 85. After the AC circuit breaker 85 is turned on, the power supply is transmitted to the start button 83 and the power off button 84. Turn on the start button 83 (press), and the power supply flows to the DC circuit breaker 86. After the DC circuit breaker 86 is turned on, the power supply is transmitted to the four AC circuit breakers 85. Among them, the maximum current of the AC circuit breaker 85 connected to the heating control module 23 is 10A, and the maximum current of the other three AC circuit breakers 85 is 2A. After the AC circuit breaker 85 connected to the heating control module 23 is turned on, it is connected to the heating component 21 to supply power to the heating component 21. The other three AC circuit breakers 85 are connected to their respective 24V switching power supply 88 or 12V switching power supply 89. The power supply outputs 24V or 12V DC power through the 24V switching power supply 88 or 12V switching power supply 89. The 12V DC power supplies power to the flow control module 36, the touch display 51 and the display driver board 52, and the 24V DC power supplies power to the solenoid valve control board 351, the solenoid valve 35 and the thermal management module 40. The flow control module 36 receives the flow information collected by the flow sensor 33 and controls the circulating pump 31 to realize the pumping and flow control of the filling liquid. The thermal management module 40 is connected to the pre-entry temperature sensor 24, the inlet temperature sensor 32, the outlet temperature sensor 34, the heating temperature sensor 22, and the temperature and humidity sensor 90. By collecting the temperature information and ambient temperature and humidity information at the corresponding locations, as well as the preset temperature information of the filling liquid set at the touch display 51, the module controls the heating power of the heating component 21 to regulate the temperature of the filling liquid in the collection tank 212, so as to achieve precise regulation of the filling liquid temperature.

[0055] After the device is powered on, users can edit the information of new and old patients through the menu on the touch display 51, and set treatment parameters such as the treatment temperature of the infusion fluid and the constant temperature time. Click "Confirm" to enter the treatment interface.

[0056] The display driver board 52 converts the signal through the display adapter board 53, and then transmits the treatment parameter signal to the flow control module 36 and the heating control module 23. The flow control module 36 controls the flow rate and time of the infusion fluid, and the heating control module 23 controls the temperature of the infusion fluid.

[0057] Click "Start Preheating" on the treatment interface of the touch display 51 to start preheating. The preheating process provides sufficient heat exchange. Before preheating is complete, the flow rate of the device will gradually decrease from 1300 ml / min to the preset flow rate. During this process, you can click "Pause Preheating" at any time as needed to stop the device from preheating.

[0058] After the heating component 21 heats the perfusion fluid in the collection tank 212 to the preset temperature, clicking "Start Treatment" on the treatment interface of the touch display 51 initiates the circulation pump 31, which pumps the perfusion fluid at the preset temperature from the collection tank 212 into the patient's body cavity via the hot perfusion treatment tubing 311. Treatment can be interrupted at any time by clicking "Stop Treatment" on the treatment page, depending on the actual situation. Alternatively, the treatment time can be set via the touch display 51, automatically stopping the treatment after the set time is reached.

[0059] Some parameters during the treatment process can be modified, such as treatment temperature and treatment time. Confirmation must be made by clicking on the touch display 51, specifically by clicking the "Modify Parameters" button. After the treatment parameters are modified, the device will restart the treatment process from the preheated perfusion solution.

[0060] Once the set treatment time is reached, the system will automatically stop heating and perfusion, stopping the treatment. The treatment interface will display a "Treatment Complete" message. Click "OK" to enter the report editing interface.

[0061] Records generated during treatment are stored in the device. Clicking "Treatment Records" in the main menu on the touch display 51 will take you to the data operation interface, where you can view, delete, export, print, and perform other operations on historical treatment data.

[0062] In summary, the intracavitary hyperthermic perfusion device provided in this application adjusts the heating temperature of the heating component in real time based on the temperature of the perfusion fluid detected by the thermal management module and the heating temperature sensor, until the perfusion fluid detected by the heating temperature sensor reaches the preset temperature. During this process, the thermal management module can also adjust the heating temperature of the heating component based on the temperature of the perfusion fluid added to the collection tank and the temperature of the perfusion fluid pumped into the body cavity, as detected by the temperature sensor before insertion and the temperature sensor after insertion, to further ensure the temperature of the perfusion fluid. Simultaneously, the flow rate of the perfusion fluid pumped by the circulating pump is detected by the flow sensor to ensure that the flow rate reaches the preset flow rate, thereby achieving precise control of the perfusion fluid temperature and flow rate and improving the therapeutic effect of the perfusion fluid.
