[0002] Heated peritoneal irrigation is an important clinical procedure in abdominal surgery and intraperitoneal hyperthermic chemotherapy. The core of this procedure is to heat the peritoneal irrigation fluid to near human body temperature or a specific treatment temperature and then stably deliver it into the abdominal cavity to clean the surgical field, maintain the patient's core body temperature during surgery, and help improve the treatment effect.

The liquid extraction tube is U-shaped and passes through multiple sets of fixing blocks. One end of the liquid extraction tube is sealed, and the other end passes through the side end of the upper cover. Multiple sets of connecting tubes are provided, and each set of connecting tubes is located at the center of a storage cavity and is inserted into each liquid bag.

[0011] As a further embodiment of the present invention: multiple sets of cutting grooves are provided, each set of cutting grooves is located above each set of vertical plates in the partition plate, and each set of vertical plates is provided with two sets of cutting grooves, which are symmetrically distributed on both sides of the horizontal plate to divide the liquid extraction tube into multiple segments. The width of the slot is the same as that of the cutting groove, and two sets of slots are provided at the top of each set of vertical plates, which are symmetrically distributed on both sides of the horizontal plate. Each set of slots is connected to a lifting groove on one side of a storage cavity.

The present invention utilizes a multi-cell storage design within the delivery component to accommodate multiple sets of irrigation fluid bags simultaneously, enabling parallel heating and independent extraction. This significantly improves the efficiency of intraoperative irrigation, adapting to the simultaneous operation requirements of multiple abdominal surgeries. The adaptive lifting and lowering structure of the float, along with the linkage control of the connecting holes and partition plates, allows for precise independent extraction of a single fluid bag, completely avoiding interference from cross-contamination between multiple fluid bags and ensuring the orderly delivery of irrigation fluid. The opening of the flow channel ensures that clean water evenly surrounds the fluid bag, improving heating uniformity and ensuring the irrigation fluid temperature remains stable within the specified range. Furthermore, the float's support design is adaptable to different specifications of fluid bags, enhancing the device's versatility and adaptability.

[0016] 2. In this invention, the conical bottom design of the exhaust box in the exhaust component allows the air in the suction tube and connecting tube to naturally rise and separate, and be discharged in an orderly manner through the exhaust hole. This completely avoids the safety risks of air bubbles entering the abdominal cavity, such as pneumoperitoneum, temperature measurement distortion, and delivery interruption. Through the cooperation of the dustproof box and the exhaust groove, air is discharged while preventing the intrusion of external impurities, ensuring a sterile environment inside the pipeline and preventing infection caused by contamination of the flushing fluid. Through the coordinated work of the exhaust box and the pump, gas-liquid separation is completed while ensuring stable delivery of the flushing fluid. This invention is suitable for different application scenarios such as conventional surgery and hyperthermic perfusion chemotherapy, improving the safety and stability of the device operation.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. In the description of this invention, it should be noted that unless otherwise explicitly specified and limited, the terms "installed," "connected," "linked," and "set up" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. The following describes embodiments of the invention based on its overall structure.

[0028] Reference Figure 1In this embodiment of the invention, a heatable peritoneal lavage fluid constant temperature delivery device includes: a heating box 1, a top cover 2 snapped onto the top of the heating box 1, a delivery component 3 disposed inside the heating box 1, and an exhaust component 4 disposed on the delivery component 3.

[0029] Reference Figure 2 The heating box 1 is filled with clean water. A limiting frame 11 is fixedly connected to the outside of the heating box 1. When the heating box 1 is engaged with the upper cover 2, the bottom end of the upper cover 2 abuts against the top end of the limiting frame 11, thereby creating a gap between the top end of the heating box 1 and the inner top end of the upper cover 2. A heating coil 12 for heating the clean water is installed through the side end of the heating box 1. A partition plate 13 is fixedly connected inside the heating box 1 and is positioned above the heating coil 12. The partition plate 13 consists of a set of horizontal plates and multiple sets of vertical plates, with the multiple sets of vertical plates being perpendicular to the horizontal plates. The length of the horizontal plates is the same as the internal length of the heating box 1, and the length of the vertical plates is the same as the internal width of the heating box 1, thereby dividing the heating box 1 into multiple identical storage cavities.

[0030] The above solution is adopted: the interior of the heating box 1 is divided into multiple independent storage chambers by the partition plate 13, so as to realize the synchronous placement, independent heating and precise extraction of multiple sets of rinsing fluid bags, thereby improving the parallel processing capability of the device. The heating coil 12 provides uniform heating of the clean water in the heating box 1 throughout the entire area, providing a stable and constant temperature heating medium for the liquid bags in the storage chamber, ensuring that the temperature of the rinsing fluid is accurately maintained within the required temperature range. The limiting frame 11 limits the engagement position of the upper cover 2 and the heating box 1, which not only ensures the stability of the installation of the upper cover 2, but also leaves a reasonable gap between the heating box 1 and the upper cover 2.

[0031] Reference Figures 3 to 6The conveying component 3 includes a horizontal plate and a vertical plate formed in the partition plate 13, and a lifting groove 31 inside the heating box 1. Multiple sets of lifting grooves 31 are evenly distributed on the four sides of each storage cavity. Lifting blocks 32 are slidably connected inside the lifting grooves 31. A float plate 33 is fixedly connected to one end of each lifting block 32. Multiple sets of float plates 33 are provided, with one set in each storage cavity. The float plate 33 has the same top-view projection area as the storage cavity. Multiple sets of lifting blocks 32 located in the same storage cavity are connected to a single set of float plates 33. A flow channel 34 is formed at the top of each float plate 33, allowing clean water to enter each storage cavity from the bottom. Multiple sets of flow channels 34 are evenly distributed on the float plates 33. In use, a liquid bag containing rinsing fluid is placed in the storage cavity, allowing each storage cavity to... Each storage chamber contains a set of liquid bags, and a float 33 in each storage chamber supports the liquid bags. When there is flushing fluid in the liquid bags, the float 33 moves downward under the gravity of the flushing fluid until the lifting block 32 moves to the bottom limit position of the lifting trough 31. When the flushing fluid in the liquid bags is used up, the float 33 moves upward under the buoyancy of the clean water until the lifting block 32 moves to the top limit position of the lifting trough 31. A fixing block 35 is fixedly connected to the top of the inside of the upper cover 2. There are multiple sets of fixing blocks 35. Two sets of fixing blocks 35 are set in the upper area of ​​each storage chamber. A liquid suction pipe 36 is inserted through the fixing blocks 35. The liquid suction pipe 36 is U-shaped and passes through multiple sets of fixing blocks 35. One end of the liquid suction pipe 36 is sealed, and the other end passes through the side end of the upper cover 2. A connecting pipe 311 is provided through the bottom end of the suction pipe 36. Multiple sets of connecting pipes 311 are provided, each set located at the center of a storage cavity and inserted into a liquid bag. A cutting groove 37 is provided through the suction pipe 36. Multiple sets of cutting grooves 37 are provided, each set located above a vertical plate in the partition plate 13. Two sets of cutting grooves 37 are provided on each vertical plate, symmetrically distributed on both sides of the horizontal plate, dividing the suction pipe 36 into multiple segments. A slot 38 is provided through the top of each vertical plate, with the width of the slot 38 matching that of the cutting groove 37. Two sets of slots 38 are provided at the top of each vertical plate, symmetrically distributed on both sides of the horizontal plate. Each slot 38 communicates with a lifting groove 31 on one side of a storage cavity, and the slot 38 is slidably inserted. Each set of partition plates 39 is installed in each set of slots 38, and the partition plates 39 are simultaneously inserted into the cutting grooves 37. The height of the partition plates 39 is greater than that of the slots 38. One end of the partition plate 39 is fixedly connected to the lifting block 32. A through hole 310 is opened on the side end of the partition plate 39. The inner diameter of the through hole 310 is the same as the inner diameter of the suction pipe 36. When the lifting block 32 moves to the bottom limit position of the lifting groove 31, the through hole 310 moves down into the slot 38. Since the height of the partition plate 39 is greater than that of the slot 38, part of the partition plate 39 is still in the cutting groove 37 at this time, isolating the suction pipe 36. When the lifting block 32 moves to the top limit position of the lifting groove 31, the through hole 310 moves up into the cutting groove 37, connecting the corresponding two sections of the suction pipe 36.This allows the rinsing solution in multiple sets of liquid bags to be extracted one by one.

[0032] The above scheme is adopted as follows: through the sliding cooperation between the lifting groove 31 and the lifting block 32 in the conveying component 3, the float 33 can adaptively move up and down according to the liquid level change in the flushing liquid in the liquid bag, and sense the liquid bag balance in real time. Through the support design that matches the top projection area of ​​the floating plate 33 and the storage cavity, it stably supports liquid bags of different sizes. At the same time, the evenly distributed flow grooves 34 on the floating plate 33 make the clean water in the heating box 1 evenly surround the liquid bag, improving the heating uniformity and temperature transfer efficiency. Through the fixed connection between the partition plate 39 and the lifting block 32, the linkage control of the connecting hole 310 moves between the slot 38 and the cutting groove 37, realizing the segmented extraction of flushing liquid from multiple sets of liquid bags, avoiding the problem of liquid cross-contamination between multiple sets of liquid bags, and ensuring the accuracy and independence of the extraction process.

[0033] Reference Figures 7 to 8 The suction tube 36 passes through the top cover 2 and is connected to an exhaust box 41. The bottom of the exhaust box 41 is conical. The top cover 2 and the exhaust box 41 are fixedly connected to a mounting bracket 44 on the same side. A pump 42 is fixedly connected inside the mounting bracket 44. The input end of the pump 42 passes through the bottom of the exhaust box 41. The output end of the pump 42 is connected to an infusion tube 43. An exhaust hole 45 is opened through the side of the exhaust box 41. A dustproof box 46 is fixedly connected to the side of the exhaust box 41. The dustproof box 46 has an L-shaped cross-section. The inside of the dustproof box 46 is connected to the exhaust hole 45. An exhaust groove is opened through the bottom of the dustproof box 46. The exhaust groove, the inside of the dustproof box 46, the exhaust hole 45 and the inside of the exhaust box 41 are connected to each other, so that the air in the suction tube 36 and the connecting tube 311 during the infusion process is separated from the liquid in the exhaust box 41.

[0034] The above solution is adopted: through the exhaust box 41 at the conical bottom of the exhaust component 4, the air in the suction tube 36 and the connecting tube 311 naturally floats up and separates from the liquid during the liquid delivery process, and is discharged from the body through the exhaust hole 45, which completely avoids the risks of air bubbles entering the abdominal cavity and causing pneumoperitoneum, temperature measurement distortion, and delivery interruption. The dustproof box 46 is connected to the exhaust hole 45, and an exhaust groove is opened at the bottom of the dustproof box 46 to achieve orderly air discharge while blocking external dust and impurities from entering the pipeline. The pump 42 provides stable power for the delivery of the irrigation fluid. With the gas-liquid separation function of the exhaust box 41, the liquid delivery process is ensured to be continuous and uninterrupted, and no air bubbles are mixed in. It is suitable for the different delivery needs of routine intraoperative constant temperature irrigation and intraperitoneal hyperthermic perfusion chemotherapy.

[0035] The working principle of this invention is as follows: Before starting the device, the liquid bags containing sterile rinsing solution are placed one by one into each storage chamber. The bottom of the liquid bags is supported by the float plate 33 in the storage chamber. At this time, the liquid bags contain sufficient rinsing solution. Under the action of gravity, the float plate 33 drives the lifting block 32 to slide downward along the lifting groove 31 until the lifting block 32 moves to the bottom limit position of the lifting groove 31. At the same time, the partition plate 39, which is fixedly connected to the lifting block 32, moves downward synchronously. The partition plate 39 is inserted into the cutting groove 37 of the suction tube 36. At this time, the connecting hole 310 moves down into the slot 38, and the partition... Plate 39 segments the suction pipe 36 to prevent cross-contamination between multiple liquid bags. Then, sufficient clean water is injected into the heating chamber 1, and the connecting pipe 311 is inserted into the liquid bag. Subsequently, the upper cover 2 is snapped onto the top of the heating chamber 1, so that the bottom end of the upper cover 2 abuts against the top of the limiting frame 11 on the outside of the heating chamber 1. Then, the heating coil 12 is activated, and the heating coil 12 uniformly heats the clean water in the heating chamber 1. During the heating process, the clean water flows evenly around the liquid bag through the partition plate 13 and the flow channel 34 inside the heating chamber 1, gradually preheating the rinsing liquid in the liquid bag to the preset temperature. Next, the pump 42 is started. The pump 42 draws the flushing fluid from the liquid bag through the suction pipe 36 and the connecting pipe 311. The air in the suction pipe 36 and the connecting pipe 311 enters the exhaust box 41 along with the liquid. Since the bottom of the exhaust box 41 is conical, the air naturally rises to the top of the exhaust box 41 and enters the dustproof box 46 through the exhaust hole 45 on the side of the exhaust box 41. Finally, it is discharged from the body through the exhaust groove at the bottom of the dustproof box 46, completing the pipeline venting. As the flushing fluid in the liquid bag gradually decreases, the gravity on the float 33 decreases, and the buoyancy of the clean water in the heating box 1 pushes the float... The plate 33 drives the lifting block 32 to move upward along the lifting groove 31 until the lifting block 32 moves to the top limit position of the lifting groove 31. At this time, the partition plate 39 fixed with the lifting block 32 moves upward synchronously, and the connecting hole 310 moves upward and inserts into the cutting groove 37, so that the two sections of the liquid extraction tube 36 corresponding to the storage cavity are connected, while the partition plates 39 corresponding to other liquid bags that have not exhausted the rinsing fluid remain in the isolation state. The device automatically switches to the rinsing fluid extraction process of the next set of liquid bags, realizing the segmented extraction of multiple sets of liquid bags without the need for manual bag replacement in the middle, ensuring the continuity of intraoperative operation.The multi-cell storage design in the conveyor 3 allows for the simultaneous storage of multiple irrigation fluid bags, enabling parallel heating and independent extraction. This significantly improves the efficiency of intraoperative irrigation and caters to the simultaneous operation requirements of multiple abdominal surgeries. The adaptive lifting structure of the float 33, along with the linkage control of the connecting hole 310 and the partition plate 39, ensures precise independent extraction of a single fluid bag, completely preventing cross-contamination and guaranteeing the orderly delivery of irrigation fluid. The flow channel 34 ensures that clean water evenly surrounds the fluid bag, improving heating uniformity and ensuring the irrigation fluid temperature remains stable within the specified range. Furthermore, the support design of the float 33 is adaptable to different sizes of fluid bags, making the lifting device universal. The device's safety and adaptability are ensured by the conical bottom design of the exhaust box 41 in the exhaust component 4, which allows air in the suction tube 36 and connecting tube 311 to naturally rise and separate, then be orderly discharged through the exhaust port 45. This completely avoids safety risks such as air bubbles entering the abdominal cavity and causing pneumoperitoneum, temperature measurement distortion, and delivery interruption. The combination of the dustproof box 46 and the exhaust channel allows air to be discharged while preventing external impurities from entering, ensuring a sterile environment inside the pipeline and preventing infection caused by contamination of the irrigation fluid. Through the coordinated work of the exhaust box 41 and the pump 42, gas-liquid separation is achieved while ensuring stable delivery of the irrigation fluid, adapting to different usage scenarios such as routine surgery and hyperthermic perfusion chemotherapy, thus improving the safety and stability of the device operation.
