[0028] This application is based on the inventor's discovery and understanding of the following facts and problems:

[0029] Intraperitoneal perfusion of drugs is often used clinically to treat malignant tumors, lymph nodes, peritoneal metastasis and other diseases. Before perfusing the drugs, the drugs need to be heated to a certain temperature and then injected into the abdominal cavity. The drugs are released after being maintained in the abdominal cavity for a certain period of time.

[0030] In the existing technology, bath water heating is usually used to heat the drug solution to a specified temperature, and then the drug solution is taken out and the heated drug solution is used for peritoneal perfusion. Since the indoor temperature is lower than the temperature of the drug solution, the temperature of the drug solution will gradually decrease during the continuous perfusion process. In addition, during the transportation process of the infusion pipeline, the drug solution passes through a narrow and long pipeline and exchanges heat with the surrounding environment, causing the temperature to drop. The low-temperature drug solution is infused into the patient's body, which will cause intestinal cramps and diarrhea in the patient, reducing the patient's comfort.

[0031] To this end, the embodiment of the present invention designs a heating and constant temperature system 1000 for peritoneal perfusion fluid that can ensure that the temperature of the medicinal liquid perfused into the patient's abdominal cavity is within a set temperature range. As a result, the temperature loss of the medicinal liquid in each link before being perfused into the patient's abdominal cavity can be compensated, ensuring that the temperature of the medicinal liquid perfused into the patient's abdominal cavity is within the set temperature range, avoiding intestinal spasms and diarrhea problems of the patient caused by low temperature of the perfused medicinal liquid, and improving the patient's comfort.

[0035] The heating constant temperature system 1000 for peritoneal perfusion fluid according to the embodiment of the utility model is described below with reference to the drawings.

[0036] As shown in Figures 1-3 The heating constant temperature system 1000 for peritoneal perfusion fluid according to the embodiment of the utility model comprises: a liquid thermostat 10, a first detection member 20 and a control module 30.

[0037] The liquid thermostat 10 is arranged at the liquid container 2001, comprising a heating member 102 and a first temperature sensor 101, the heating member 102 is used for heating the liquid in the liquid container 2001, the first temperature sensor 101 is used for detecting the temperature of the liquid in the liquid container 2001, the control module 30 is in communication connection with the heating member 102 and the first temperature sensor 101, and the heating member 102 is controlled to operate according to the temperature detected by the first temperature sensor 101.

[0038] Specifically, before the abdominal perfusion operation is performed, the medicine container 2001 can be first placed in the medicine thermostat 10, and the medicine is heated by the medicine thermostat 10. At this time, the temperature of the medicine is low, the first temperature sensor 101 detects that the temperature of the medicine is lower than the lowest preset temperature, the control module 30 obtains the information and controls the heating element 102 of the medicine thermostat 10 to be turned on. Since the abdominal perfusion operation is not performed, the first detection element 20 is not installed on the infusion pipeline 2002, and the first detection element 20 is closed.

[0039] During the heating process, the first temperature sensor 101 detects the temperature of the medicine in the medicine container 2001 in real time. After heating to the preset temperature, the first temperature sensor 101 detects that the temperature of the medicine in the medicine container 2001 is higher than the highest preset temperature, the control module 30 obtains the information and controls the heater to be turned off. After the heater is turned off, the temperature of the medicine in the medicine container 2001 slowly decreases. After decreasing to the lowest preset temperature, the first temperature sensor 101 detects that the temperature of the medicine in the medicine container 2001 is lower than the lowest preset temperature, the control module 30 obtains the information and controls the heater to be turned on. Before the medicine is perfused, the medicine thermostat 10 always keeps the medicine in the medicine container 2001 within the range of the lowest preset temperature and the highest preset temperature.

[0040] That is, when the first temperature sensor 101 detects that the temperature of the medicine in the medicine container 2001 is higher than the highest preset temperature, the control module 30 controls the heating element 102 to be turned off. When the first temperature sensor 101 detects that the temperature of the medicine in the medicine container 2001 is lower than the lowest preset temperature, the control module 30 controls the heating element 102 to be turned on. Thus, it is ensured that the temperature of the medicine is kept within the range of the lowest preset temperature and the highest preset temperature.

[0041] After the abdominal perfusion operation is performed, the medicine container 2001 is communicated with the infusion pipeline 2002, and the medicine is perfused into the abdominal cavity through the infusion pipeline 2002. The first detection element 20 is detachably fixed on the infusion pipeline 2002 and arranged on the side of the infusion pipeline 2002 close to the human body. The first detection element 20 includes a second temperature sensor 201 for detecting the temperature of the medicine in the infusion pipeline 2002, that is, detecting the accurate temperature of the medicine perfused into the patient's body. The control module 30 is in communication connection with the heating element 102, the first temperature sensor 101 and the second temperature sensor 201, and controls the heating element 102 to operate according to the temperature detected by the first temperature sensor 101 and the temperature detected by the second temperature sensor 201.

[0042] At this time, the control module 30 can simultaneously receive the temperature information detected by the first temperature sensor 101 and the second temperature sensor 201. During the process of conveying the drug solution in the infusion pipeline 2002, the drug solution exchanges heat with the surrounding environment due to the narrow and long pipeline, so that the temperature of the drug solution is reduced. The temperature value information of the drug solution in the infusion pipeline 2002 is closer to the temperature of the drug solution perfused into the abdominal cavity of the patient. The temperature value information of the drug solution in the infusion pipeline 2002 detected by the second temperature sensor 201 is lower than the temperature value information of the drug solution in the drug solution container 2001 detected by the first temperature sensor 101. The temperature difference between the temperature detected by the first temperature sensor 101 and the temperature detected by the second temperature sensor 201 is different under different environmental temperatures and different pipeline lengths.

[0043] Therefore, after the abdominal perfusion operation is performed, when the temperature of the drug solution in the drug solution container 2001 is at a certain temperature value between the lowest preset temperature and the highest preset temperature, the second temperature sensor 201 detects that the temperature value of the drug solution in the infusion pipeline 2002 is lower than the lowest preset temperature value. The control module 30 obtains that the temperature of the drug solution in the infusion pipeline 2002 detected by the second temperature sensor 201 is lower than the lowest preset temperature value. The control module 30 controls the heating element 102 to be turned on. Therefore, the temperature of the drug solution in the drug solution container 2001 is kept within the range of the intermediate temperature and the highest preset temperature, and the temperature of the drug solution conveyed to the patient by the infusion pipeline 2002 can be kept within the range of the lowest preset temperature and the highest preset temperature. The heat loss of the drug solution in each link before being perfused into the abdominal cavity of the patient can be supplemented by the timely heating of the heating element 102, so that the temperature of the drug solution perfused into the abdominal cavity of the patient is within the set temperature range, the problem of overcooling of the perfused drug solution is avoided, the problems of intestinal spasm and diarrhea of the patient caused by low perfused drug solution temperature are avoided, and the comfort of the patient is improved.

[0044] The heating constant temperature system 1000 for abdominal perfusion liquid according to the embodiment of the utility model ensures that the temperature of the drug solution perfused into the abdominal cavity of the patient is within the set temperature range, avoids the problems of intestinal spasm and diarrhea of the patient caused by low perfused drug solution temperature, and improves the comfort of the patient.

[0045] Specifically, referring to Figure 1 In some embodiments, the control module 30 obtains the temperature information detected by the first temperature sensor 101 and / or the second temperature sensor 201. When any one of the obtained temperature values is lower than the first preset temperature value, the control module 30 controls the heating element 102 to heat the drug solution in the drug solution container 2001. When any one of the obtained temperature values is higher than the second preset temperature value, the control module 30 controls the heating element 102 to stop heating.

[0046] That is, before the abdominal perfusion, the heating constant temperature system 1000 for the abdominal perfusion liquid uses the medicine liquid thermostat 10 to heat the medicine liquid in the medicine liquid container 2001, the control module 30 only acquires the temperature information detected by the first temperature sensor 101, when the temperature information detected by the first temperature sensor 101 is lower than the first preset temperature value, the control module 30 controls the heating part 102 to heat the medicine liquid in the medicine liquid container 2001, when the temperature information detected by the first temperature sensor 101 is higher than the second preset temperature value, the control module 30 controls the heating part 102 to stop heating, thus, the medicine liquid in the medicine liquid container 2001 is first heated from normal temperature to the second preset temperature value and is kept at the first preset temperature value and the second preset temperature value.

[0047] After the abdominal perfusion, the medicine liquid container 2001 is communicated with the infusion pipeline 2002, the medicine liquid is perfused into the abdominal cavity through the infusion pipeline 2002, the first detection part 20 is fixed on the infusion pipeline 2002, the first detection part 20 comprises the second temperature sensor 201, the second temperature sensor 201 detects the temperature of the medicine liquid in the infusion pipeline 2002, the control module 30 simultaneously acquires the temperature value information detected by the first temperature sensor 101 and the second temperature sensor 201, since the temperature of the medicine liquid in the medicine liquid container 2001 is higher than the temperature of the medicine liquid in the infusion pipeline 2002, when the temperature information detected by the second temperature sensor 201 is equal to or lower than the first preset temperature value, the control module 30 controls the heating part 102 to heat the medicine liquid in the medicine liquid container 2001, at this time, the temperature information detected by the first temperature sensor 101 is an intermediate temperature value between the first preset temperature value and the second preset temperature value, when the temperature value information detected by the first temperature sensor 101 is higher than the second preset temperature value, the control module 30 controls the heating part 102 to stop heating, thus, the medicine liquid in the medicine liquid container 2001 is kept at the intermediate temperature value and the second preset temperature value. The temperature value of the medicine liquid input into the patient's body is limited between the first preset temperature value and the second preset temperature value.

[0048] When any one of the first temperature sensor 101 and the second temperature sensor 201 fails, the control module 30 can control the heating part 102 according to the temperature value detected by the other temperature sensor, to avoid the over-heated or over-cooled medicine liquid from being delivered into the patient's body, thus improving the safety.

[0049] When the temperature of the liquid medicine in the liquid medicine container 2001 is the second preset temperature value and the temperature of the liquid medicine in the infusion pipeline 2002 is lower than the first preset temperature value, the control module 30 acquires the temperature information detected by the first temperature sensor 101 and / or the second temperature sensor 201. When the temperature value acquired by any one of the first temperature sensor 101 and the second temperature sensor 201 is lower than the first preset temperature value, the control module 30 controls the heating element 102 to heat the liquid medicine in the liquid medicine container 2001. When the temperature value acquired by the second temperature sensor 201 is higher than the second preset temperature value, the control module 30 controls the heating element 102 to stop heating. When the temperature value acquired by the first temperature sensor 101 is higher than the fourth preset temperature value, the control module 30 controls the heating element 102 to stop heating. The fourth preset temperature value is higher than the second preset temperature value. When the temperature of the liquid medicine in the liquid medicine container 2001 is the fourth preset temperature value, the temperature of the liquid medicine in the infusion pipeline 2002 is not lower than the first preset temperature value.

[0050] Specifically, after the peritoneal perfusion is performed, the control module 30 simultaneously acquires the temperature information detected by the first temperature sensor 101 and the second temperature sensor 201. Since the temperature of the liquid medicine in the liquid medicine container 2001 is higher than the temperature of the liquid medicine in the infusion pipeline 2002, when the temperature information detected by the second temperature sensor 201 is lower than the first preset temperature value, the control module 30 controls the heating element 102 to heat the liquid medicine in the liquid medicine container 2001. At this time, the temperature information detected by the first temperature sensor 101 is an intermediate temperature value between the first preset temperature value and the fourth preset temperature value.

[0051] When the temperature information detected by the second temperature sensor 201 is higher than the second preset temperature value or the temperature information detected by the first temperature sensor 101 is higher than the fourth preset temperature value, the control module 30 controls the heating element 102 to stop heating. In this way, the liquid medicine in the liquid medicine container 2001 is kept at an intermediate temperature value between the fourth preset temperature value and the second preset temperature value. The temperature of the liquid medicine input into the patient's body is limited to be between the first preset temperature value and the second preset temperature value.

[0052] For different peritoneal perfusion needs of different patients, there are two different perfusion modes, i.e., a medium-temperature perfusion mode with a perfusion temperature between 37 degrees Celsius and 38 degrees Celsius and a high-temperature perfusion mode with a perfusion liquid temperature between 41 degrees Celsius and 45 degrees Celsius. Correspondingly, the heating constant-temperature system 1000 for peritoneal perfusion liquid can include a first mode and a second mode. In the first mode, the first preset temperature value is 37 degrees Celsius and the second preset temperature value is 38 degrees Celsius, so as to correspond to the medium-temperature perfusion mode. In the second mode, the first preset temperature value is 41 degrees Celsius and the second preset temperature value is 45 degrees Celsius, so as to correspond to the high-temperature perfusion mode.

[0053] As Figure 3As shown, the medicine constant temperature device 10 further comprises a control panel 103, the control module 30 is in communication connection with the control panel 103, used for collecting the operation information of the control panel 103, determining the selected function mode, generating the corresponding control instruction, specifically, the control panel 103 can include a first button and a second button for selecting the mode, the user selects the function mode of the control module 30 through the button on the control panel 103, when the user clicks the first button, the control module 30 controls the heating constant temperature system 1000 to run in the first mode, when the user clicks the second button, the control module 30 controls the heating constant temperature system 1000 to run in the second mode.

[0054] In other embodiments, the heating constant temperature system 1000 can also be personalized according to the user's needs to customize the constant temperature temperature of the medicine liquid of the heating constant temperature system 1000, the user can set the first preset temperature value and the second preset temperature value through the control panel 103, and control the temperature of the medicine liquid in the required temperature range according to the needs.

[0055] Referring to Figure 1 In order to avoid the failure of the heating constant temperature system 1000 for abdominal perfusion liquid, the overheating of the medicine liquid caused by the out-of-control of the heating element 102, the heating constant temperature system 1000 further comprises an alarm module 40, the control module 30 is in communication with the alarm module 40, the control module 30 acquires the temperature information detected by the first temperature sensor 101 and / or the second temperature sensor 201, when any one of the acquired temperature values is higher than the third preset temperature value, the control module 30 is adapted to control the alarm module 40 to send alarm information, at this time, the user can control the medicine constant temperature device 10 to be powered off to stop the continuous heating of the medicine liquid by the heating element 102, avoid the direct perfusion of the overheated medicine liquid into the patient's body caused by the heating of the medicine liquid by the heating element 102 above the third preset temperature value, which causes harm to the patient, and avoid the change of the nature of the medicine liquid caused by the heating of the medicine liquid above the third preset temperature value, which affects the effect of the medicine liquid.

[0056] Further, in order to avoid the air entering the patient's body during the process of perfusing the medicine liquid, causing the patient to have abdominal distension and other problems, the air alarm 202 is further arranged on the first detection element 20, the air alarm 202 detects whether there is air in the infusion pipeline 2002, when there is air in the infusion pipeline 2002, the alarm information is sent to prompt the user to handle, avoiding the air being perfused into the patient's body.

[0057] Specifically, referring to Figure 2 and Figure 3The medicine liquid thermostat 10 comprises a heating container 1, which defines a containing space 3 with an opening 2 at the top, and a medicine liquid container 2001 is movably arranged in the containing space 3 through the opening 2. The medicine liquid container 2001 is heated by being arranged in the containing space 3 defined by the heating container 1, and the medicine liquid thermostat 10 can ensure the temperature in the containing space 3 defined by the heating container 1, thereby controlling the temperature of the medicine liquid in the medicine liquid container 2001. The containing space 3 has the opening 2 at the top, so as to facilitate the placement and replacement of the medicine liquid container 2001, and ensure the reuse of the medicine liquid thermostat 10. The containing space 3 is provided with a liquid outlet 4 at the bottom, and a joint 2003 of the medicine liquid container 2001 passes through the liquid outlet 4 and communicates with a liquid delivery pipeline 2002 outside the containing space 3.

[0058] Further, referring to Figure 3 The heating container 1 comprises an inner container 11 and an outer sleeve 12. The inner container 11 is wrapped outside the medicine liquid container 2001 and defines the containing space 3. The outer sleeve 12 is sleeved outside the inner container 11 and filled with a heating medium between the inner container 11 and the outer sleeve 12. The heating element 102 indirectly heats the medicine liquid in the medicine liquid container 2001 by heating the heating medium. The arrangement of the heating medium can ensure that the temperature is uniform at all places around the medicine liquid container 2001, and the medicine liquid in the medicine liquid container 2001 can be uniformly heated. By controlling the temperature of the heating medium to be kept within a preset temperature range, the temperature of the medicine liquid in the medicine liquid container 2001 can be kept within the preset temperature range, avoiding direct heating of the medicine liquid and avoiding the occurrence of denaturation of the medicine during the heating process.

[0059] The inner container 11 is made of a deformable aluminum foil material. The inner container 11 is deformable, and can be deformed by extruding the space of the containing space 3 during the process of arranging the medicine liquid container 2001 in the containing space 3, so as to ensure that the inner container 11 closely adheres to the medicine liquid container 2001, and ensure the heating effect of the medicine liquid in the medicine liquid container 2001 by the medicine liquid thermostat 10, avoiding the existence of gaps between the inner container 11 and the medicine liquid container 2001, which causes heat loss.

[0060] In addition, the perfusion medicine used in the chemotherapy process is generally some immune-regulating medicine, such as cisplatin, oxaliplatin, and paclitaxel. Since the aluminum foil material has the properties of safety, stability, environmental protection, heat resistance, moisture resistance, light resistance, and the like, it will not release harmful substances or deform after heating, and is more suitable for storing the above-mentioned light-resistant medicine. In addition, the volume of the containing space 3 is at least not less than 500 milliliters, so as to ensure that the containing space 3 has enough space to accommodate most of the medicine liquid containers 2001, and ensure the versatility of the medicine liquid thermostat 10.

[0061] As Figure 2 and Figure 3As shown, the heating container 1 comprises an upper cover 5, which is movable between a position of opening the opening 2 and a position of closing the opening 2, in the position of opening the opening 2, the opening 2 of the accommodating space 3 is opened, and a user can put or take out the medicine liquid container 2001 into or from the accommodating space 3 through the opened opening 2.

[0062] The upper cover 5 can be fixed at the position of closing the opening 2 to close the accommodating space 3 after the medicine liquid container 2001 is put into the accommodating space 3, ensure the heat preservation effect of the accommodating space 3, and fix the medicine liquid container 2001 and the heating container 1 together, which is convenient for integrated movement and fixing, specifically, the upper cover 5 and the outer surface of the outer sleeve 12 are provided with fixing members 6, the fixing members 6 provided on the upper cover 5 and the fixing members 6 provided on the outer surface of the outer sleeve 12 cooperate to detachably fix the upper cover 5 and the outer sleeve 12 together. The fixing members 6 can be magic tapes.
