Description

Technical Field

[0001] This invention relates to the field of gastrointestinal irrigation technology, and more specifically, to a decompression irrigation device for gastrointestinal surgical care. Background Technology

[0002] In the clinical nursing care of gastrointestinal surgery, irrigating postoperative wounds or stomas is a common and crucial procedure. Its purpose is to remove exudate, food debris, and necrotic tissue, maintaining local cleanliness to prevent infection and promote healing. Traditional irrigation methods often rely on simple containers (such as enema bags or syringes) and saline solution. The technique, fluid temperature, and pressure all depend on the manual control and experience of medical staff. This traditional method has several significant drawbacks: Firstly, regarding temperature control, the irrigation solution is usually simply preheated externally, making it difficult to maintain a constant, suitable temperature. If the liquid temperature is too low, it can irritate the patient's gastrointestinal tract, causing discomfort such as spasms and abdominal pain; if the temperature is too high, there is a risk of burning the mucous membranes. This uneven temperature experience not only increases the patient's suffering but also hinders tissue recovery.

[0003] Secondly, regarding irrigation pressure, manual operation or simple gravity dripping cannot achieve precise and stable pressure control. Excessive pressure may impact and damage the fragile postoperative wound, even leading to serious complications such as anastomotic leakage; insufficient pressure will fail to effectively remove attached material, affecting the irrigation effect. The few existing electric irrigation devices have limited pressure adjustment ranges and lack reliable real-time decompression mechanisms.

[0004] Furthermore, regarding liquid mixing and heating efficiency, traditional devices or single-tank equipment are prone to temperature stratification due to insufficient heat convection when heating the cleaning fluid, resulting in uneven heating of the liquid inside the tank. This leads to continuous temperature fluctuations in the output liquid, affecting the comfort and safety of nursing care. Simultaneously, the heating efficiency is low, often requiring a long time to reach the set temperature, making it difficult to meet the needs of continuous clinical operations. Summary of the Invention

[0005] This invention proposes a decompression irrigation device for gastrointestinal surgical care, which solves the problems of insufficient temperature control and poor irrigation effect in related technologies.

[0006] The technical solution of the present invention is as follows: A decompression flushing device for gastrointestinal surgical care includes a main component, which is composed of a main tank and a preheating tank connected to each other in sequence along an axial position. A water outlet pipe is provided at the bottom of the main tank, and a water inlet pipe is provided at the top of the preheating tank. A heating component for heating the cleaning fluid is provided inside the main tank, and a preheating component for preheating the cleaning fluid is provided inside the preheating tank.

[0007] As a preferred embodiment of the present invention, the outlet end of the water outlet pipe is provided with a water pump for discharging liquid, and the tail end of the water outlet pipe is provided with a pressure reducing valve for discharging liquid under reduced pressure.

[0008] In a preferred embodiment of the present invention, the preheating assembly consists of a preheating plate and a limiting rotating frame.

The top of the limiting rotating frame is provided with a plurality of cover plates, and the top of the main tank is provided with a number of through slots equal to the number of cover plates.

[0009] As a preferred embodiment of the present invention, a first internal gear ring is fixedly connected to the inner wall of the limiting rotating frame, a servo motor is installed on the top of the inner wall of the preheating tank, and the output end of the servo motor is connected to a coaxially arranged drive gear through a coupling, the drive gear meshing with the first internal gear ring.

[0010] In a preferred embodiment of the present invention, the heating assembly consists of a drive motor, which is installed on the top of the main tank. The output end of the drive motor is equipped with a drive shaft, and a plurality of equidistantly distributed main arc-shaped stirring rods are fixedly sleeved on the outer circumferential surface of the drive shaft.

[0011] As a preferred embodiment of the present invention, a plurality of circumferentially distributed follower shafts are rotatably installed inside the main tank, and a plurality of equally spaced secondary arc-shaped stirring rods are fixedly sleeved on the outer circumferential surface of the follower shafts.

[0012] As a preferred embodiment of the present invention, a transmission frame is rotatably installed inside the main tank, and two symmetrically arranged transmission bearings are fixedly sleeved on the outer circumferential surface of the transmission frame. A plurality of equidistantly distributed inner arc-shaped stirring rods are fixedly connected to the inner wall of the transmission frame.

[0013] As a preferred embodiment of the present invention, a transmission gear is fixedly sleeved on the drive shaft, and a follower gear is fixedly sleeved on the outer circumferential surface of the follower shaft. The transmission gear and the follower gear mesh with each other. A second internal gear ring is fixedly connected to the inner wall of the transmission frame, and the second internal gear ring meshes with the follower shaft.

[0014] The working principle and beneficial effects of this invention are as follows: 1. This invention, through the design of preheating plates and main tank, etc., preheating plates initially heat up the liquid, and then a high-intensity composite flow field is formed by the multi-axis linkage arc-shaped stirring rod assembly and the transmission circular frame, which completely eliminates temperature stratification, ensures that the output liquid temperature is constant and uniform, and effectively avoids damage to the patient's gastrointestinal tract caused by hot and cold stimulation.

[0015] 2. This invention, through the setting of structures such as the limiting rotating frame and the cover plate, enables the limiting rotating frame driven by the servo motor to achieve batch liquid supply through the periodic opening and closing of the through slot by the cover plate.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. 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 of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0020] Example like Figures 1-7 As shown, a decompression flushing device for gastrointestinal surgical care includes a main component 100, characterized in that: the main component 100 is composed of a main tank 101 and a preheating tank 102 connected to each other in sequence along the axial direction; a water outlet pipe 104 is provided at the bottom of the main tank 101, a water inlet pipe 103 is provided at the top of the preheating tank 102, a heating component 300 for heating the cleaning fluid is provided inside the main tank 101, and a preheating component 200 for preheating the cleaning fluid is provided inside the preheating tank 102.

[0021] The main component 100 of a decompression irrigation device for gastrointestinal surgical care is the core of the device. It consists of a main tank 101 and a preheating tank 102 connected axially along an axis. The main tank 101 and the preheating tank 102 are sealed and fixed by flanges or threads to prevent leakage. A water outlet pipe 104 is provided at the bottom of the main tank 101 for discharging heated cleaning fluid; a water inlet pipe 103 is provided at the top of the preheating tank 102 for receiving externally input cleaning fluid. A heating component 300 is installed inside the main tank 101, which is responsible for the final heating of the cleaning fluid to ensure a suitable temperature for gastrointestinal surgical care. A preheating component 200 is installed inside the preheating tank 102, which preheats the cleaning fluid, reducing the heating load on the main tank and improving energy efficiency. In terms of working principle, the cleaning fluid enters the preheating tank 102 through the inlet pipe 103. After being initially heated by the preheating component 200, it flows into the main tank 101 through the connecting channel. It is then further heated by the heating component 300 and finally output from the outlet pipe 104. The dual-tank design realizes the stepped heating of the cleaning fluid, avoiding the stimulation of the patient's gastrointestinal tract by sudden temperature changes, while improving heating efficiency and ensuring that the rinsing process is safe and comfortable. It is suitable for frequent use in medical environments. The axial connection method of the main component 100 also facilitates disassembly, cleaning and maintenance, and meets the hygiene standards of gastrointestinal surgical care.

[0022] The outlet end of the water outlet pipe 104 is equipped with a water pump 105 for discharging liquid, and the tail end of the water outlet pipe 104 is equipped with a pressure reducing valve 106 for depressurizing liquid discharge.

[0023] A water pump 105 is installed at the outlet end of the water outlet pipe 104, and a pressure reducing valve 106 is installed at the tail end. The water outlet pipe 104 is typically connected using medical-grade flexible or rigid tubing to ensure sterility and durability. The water pump 105, installed at the outlet end of the water outlet pipe 104, works by using a motor to drive an impeller to rotate, generating negative pressure to draw in the cleaning fluid and pressurize it for output, thus achieving continuous and controllable fluid delivery. The electrical components of the water pump 105 include a motor and a controller. The motor rotates after receiving a power signal, driving the impeller. The controller can adjust the speed to control the flow rate, meeting different nursing needs. The pressure reducing valve 106, installed at the tail end of the water outlet pipe 104, uses a mechanical or electronic pressure regulation mechanism. When the cleaning fluid pressure is too high, the spring or diaphragm structure inside the pressure reducing valve 106 automatically adjusts the opening to reduce the output pressure, ensuring a gentle and safe flushing process and avoiding damage to the patient's gastrointestinal tract. The coordinated operation of the water pump 105 and the pressure reducing valve 106 enables the device to achieve pressure-reduced flushing: the water pump 105 provides power to pump the heated cleaning fluid out of the main tank 101, while the pressure reducing valve 106 stabilizes the output pressure. This is suitable for sensitive tissues in gastrointestinal surgical care, which not only improves the comfort of flushing, but also realizes automated operation through electrical control, reducing the operational burden on medical staff. The entire water outlet assembly has a simple and reliable structure and is easy to integrate into medical equipment.

[0024] The preheating assembly 200 consists of a preheating plate 201 and a limiting rotating frame 204. The preheating plate 201 is disposed on the inner wall of the preheating tank 102, and the limiting rotating frame 204 is rotatably mounted on the bottom wall of the preheating tank 102. The top of the limiting rotating frame 204 is provided with several cover plates 206, and the top of the main tank 101 is provided with a number of through slots equal to the number of cover plates 206.

[0025] The preheating component 200 of the decompression irrigation device for gastrointestinal surgery is installed inside the preheating tank 102. It consists of a preheating plate 201 and a limiting rotating frame 204. The preheating plate 201 is fixedly installed on the inner wall of the preheating tank 102 and is typically made of a metal thermally conductive material. It transfers heat through resistance heating or an external heat source to initially heat the flowing cleaning fluid. The electrical connection of the preheating plate 201 includes a heating element and a temperature controller. The heating element generates heat after being energized, and the temperature controller monitors the temperature and adjusts the current to prevent overheating. The limiting rotating frame 204 is rotatably installed on the bottom wall of the preheating tank 102. Smooth rotation is achieved via bearings or bushings. Several cover plates 206 are mounted on the top of the main tank 101, with a number and corresponding positions to the number of through-slots on the top. When the limiting rotating frame 204 rotates, the cover plates 206 periodically open or close the through-slots, controlling the flow rate of cleaning fluid from the preheating tank 102 to the main tank 101. The cleaning fluid enters the preheating tank 102 through the inlet pipe 103, where it is heated by the preheating plates 201. Simultaneously, the rotation of the limiting rotating frame 204 moves the cover plates 206, adjusting the opening and closing of the through-slots to achieve batch delivery of the cleaning fluid and avoid uneven mixing of hot and cold fluids. This design not only improves preheating efficiency but also ensures uniform heating of the cleaning fluid through a mechanical structure. The rotation of the limiting rotating frame 204 is controlled by an external drive device, making it suitable for long-term use in medical environments.

[0026] A first internal gear ring 205 is fixedly connected to the inner wall of the limiting rotating frame 204. A servo motor 202 is installed on the top of the inner wall of the preheating tank 102. The output end of the servo motor 202 is connected to a coaxially arranged drive gear 203 through a coupling. The drive gear 203 meshes with the first internal gear ring 205.

[0027] The driving mechanism of the preheating component 200 of the decompression irrigation device for gastrointestinal surgery involves the meshing transmission of a servo motor 202, a drive gear 203, and a first internal gear ring 205. The servo motor 202 is mounted on the top of the inner wall of the preheating tank 102. Its working principle is to drive the output shaft to rotate by receiving control signals. The output shaft is coaxially connected to the drive gear 203 through a coupling to ensure the synchronicity and stability of power transmission. The electrical part of the servo motor 202 includes an encoder and a controller. The encoder provides feedback on position information, and the controller adjusts the motor speed and direction. The drive gear 203 meshes with the first internal gear ring 205, which is fixedly connected to the inner wall of the limiting rotating frame 204, forming a gear transmission system. When the servo motor 202 starts, the drive gear 203 rotates, driving the first internal gear ring 205 and the limiting rotating frame 204 to rotate together. This internal gear ring design increases the transmission contact area and improves torque transmission efficiency, enabling the limiting rotating frame 204 to rotate smoothly and at low speed, thereby controlling the opening and closing of the cover plate 206 to the through slot. The entire transmission process is smooth and low-noise, making it suitable for quiet operation in medical environments. The drive mechanism is based on the fundamental mechanics of gear meshing. The servo motor 202 provides a controllable power source, and through the deceleration action of the drive gear 203 and the first internal gear ring 205, precise position control of the limit rotating frame 204 is achieved. This ensures that the cleaning fluid has a moderate residence time in the preheating tank 102, resulting in uniform preheating, improving the automation and reliability of the device, and reducing manual intervention.

[0028] The heating component 300 consists of a drive motor 301, which is installed on the top of the main tank 101. The output end of the drive motor 301 is equipped with a drive shaft 302, and several equidistantly distributed main arc-shaped stirring rods 304 are fixedly sleeved on the outer circumferential surface of the drive shaft 302.

[0029] The heating component 300 of the decompression flushing device for gastrointestinal surgery is located inside the main tank 101. It consists of a drive motor 301, a drive shaft 302, and main arc-shaped stirring rods 304. The drive motor 301 is mounted on the top of the main tank 101. Its working principle is to convert electrical energy into mechanical energy to drive the output shaft to rotate. The electrical part of the drive motor 301 includes a stator and a rotor. When the stator winding is energized, it generates a rotating magnetic field, which drives the rotor to rotate and output torque. The drive shaft 302 is coaxially connected to the output end of the drive motor 301 through a coupling or keyway to ensure direct power transmission. Several equidistant main arc-shaped stirring rods 304 are fixedly sleeved on the outer circumference of the drive shaft 302. These stirring rods adopt an arc design to increase the contact area with the cleaning fluid and improve the stirring efficiency. When the drive motor 301 is started, the drive shaft 302 drives the main arc-shaped stirring rods 304 to rotate, which performs forced convection and shear stirring on the cleaning fluid in the main tank 101, so that the heat is evenly distributed and avoids local overheating. The heating principle of the heating element 300 typically combines an external heating source, such as a heating wire or a hot water jacket, with stirring: stirring accelerates heat transfer, while the heating source provides continuous heat energy. This design ensures that the cleaning fluid quickly reaches the set temperature and remains stable, making it suitable for continuous flushing in gastrointestinal surgical care. The drive motor 301 has an adjustable speed, allowing for different stirring intensities via a controller to adapt to various nursing needs. The arc-shaped design of the stirring rod reduces fluid resistance, lowers energy consumption, and simultaneously improves heating uniformity and efficiency.

[0030] The main tank 101 has several circumferentially distributed follower shafts 305 rotatably mounted inside, and several equally spaced secondary arc-shaped stirring rods 307 are fixedly sleeved on the outer circumferential surface of the follower shafts 305.

[0031] The heating component 300 of the decompression flushing device for gastrointestinal surgery includes a follower shaft 305 and auxiliary arc-shaped stirring rods 307. These components are installed inside the main tank 101. Several follower shafts 305 are evenly distributed and rotatably mounted on the inner wall of the main tank 101, supported by bearings or sealing sleeves to ensure smooth rotation. Several equidistantly distributed auxiliary arc-shaped stirring rods 307 are fixedly fitted onto the outer circumferential surface of each follower shaft 305. These stirring rods also employ an arc-shaped design to generate eddies and turbulence, enhancing the mixing effect. The rotation of the follower shafts 305 is not directly driven by a motor, but is linked to the drive shaft 302 via gears or other transmission mechanisms. When the drive shaft 302 rotates, it drives the follower shafts 305 to rotate synchronously or asynchronously. The auxiliary arc-shaped stirring rods 307 cooperate with the main arc-shaped stirring rods 304 to form a multi-directional stirring mode, breaking up temperature stratification in the cleaning fluid and promoting uniform heat distribution. In terms of working principle, the curved surface of the auxiliary arc-shaped stirring rod 307 generates thrust and lift on the fluid during rotation, accelerating heat exchange and reducing dead zones. This ensures that the cleaning fluid within the entire main tank 101 is heated uniformly, making it suitable for heating high-viscosity or large-volume cleaning fluids. The optimized installation position of the follower shaft 305, with its circumferential distribution, ensures torque balance, reducing vibration and wear. The equidistant distribution of the stirring rods guarantees continuous and stable stirring action, improving the overall performance and reliability of the heating assembly 300 and meeting the temperature control requirements of gastrointestinal surgical care.

[0032] The main tank 101 is rotatably mounted with a transmission frame 308. Two symmetrically arranged transmission bearings 310 are fixedly sleeved on the outer circumference of the transmission frame 308. Several equidistantly distributed inner arc-shaped stirring rods 311 are fixedly connected to the inner wall of the transmission frame 308.

[0033] The heating component 300 of the decompression flushing device for gastrointestinal surgery includes a transmission frame 308, a transmission bearing 310, and an inner arc-shaped stirring rod 311, which enhances the stirring effect and structural stability. The transmission frame 308 is rotatably mounted on the inner wall of the main tank 101 and is fixedly supported by two symmetrically arranged transmission bearings 310. The outer ring of the transmission bearing 310 is connected to the main tank 101, and the inner ring is fixed to the transmission frame 308, ensuring that the frame can rotate freely and withstand radial and axial loads. Several equidistantly distributed inner arc-shaped stirring rods 311 are fixedly connected to the inner wall of the transmission frame 308. These stirring rods adopt an inwardly convex arc design, forming a complementary stirring mode with the main arc-shaped stirring rod 304 and the secondary arc-shaped stirring rod 307 during rotation. The inner arc-shaped stirring rods 311 apply force to the cleaning fluid from the circumferential direction, generating centripetal flow and further eliminating heating dead zones. The rotation of the transmission frame 308 is driven by an external drive mechanism such as gears, which transmits torque through the transmission bearing 310, allowing the inner arc-shaped stirring rods 311 to rotate at a lower speed, working in coordination with the internal stirring rods to achieve multi-level, multi-directional fluid mixing. This design improves the uniformity and efficiency of stirring, ensuring a consistent temperature distribution of the cleaning fluid during heating and avoiding local overheating or cooling. The structure of the transmission frame 308 also serves a supporting and guiding function, enhancing the overall rigidity of the main tank 101 and reducing vibration and noise. The entire assembly operates smoothly through mechanical transmission. The equidistant distribution of the inner arc-shaped stirring rods 311 optimizes the fluid dynamics performance, making it suitable for long-term, high-load medical use and improving the safety and comfort of the gastrointestinal surgical nursing flushing device.

[0034] A transmission gear 303 is fixedly sleeved on the drive shaft 302, and a follower gear 306 is fixedly sleeved on the outer circumferential surface of the follower shaft 305. The transmission gear 303 and the follower gear 306 mesh with each other. A second internal gear ring 309 is fixedly connected to the inner wall of the transmission frame 308, and the second internal gear ring 309 meshes with the follower shaft 305.

[0035] The gear transmission system of the heating component 300 of the decompression flushing device for gastrointestinal surgery nursing consists of a transmission gear 303, a follower gear 306, and a second internal gear ring 309, realizing the coordinated transmission between the drive shaft 302, the follower shaft 305, and the transmission ring 308. The transmission gear 303 is fixedly sleeved on the drive shaft 302, and the follower gear 306 is fixedly sleeved on the outer circumferential surface of each follower shaft 305. The transmission gear 303 and the follower gear 306 mesh with each other to form a first-stage gear transmission: when the drive motor 301 drives the drive shaft 302 to rotate, the transmission gear 303 drives the follower gear 306 to rotate, thereby causing the follower shaft 305 and the auxiliary arc-shaped stirring rod 307 to move synchronously. The second internal gear ring 309 is fixedly connected to the inner wall of the transmission frame 308 and meshes with the follower gear 306 on the follower shaft 305, forming a two-stage gear transmission. The rotation of the follower shaft 305 drives the transmission frame 308 to rotate through the meshing of the follower gear 306 and the second internal gear ring 309, thereby driving the inner arc-shaped stirring rod 311 to work. The working principle of the entire gear transmission system is based on the mechanical principle of gear meshing. The transmission gear 303, as the driving component, transmits power to the follower gear 306, and then the second internal gear ring 309 realizes the deceleration or acceleration of the rotation of the transmission frame 308, ensuring the coordinated operation of each component. This design realizes multi-axis synchronous drive, improves the coverage and efficiency of stirring, and allows the cleaning fluid to be fully mixed and heated in the main tank 101. The gear transmission has high reliability and accuracy, reduces sliding losses, and is suitable for continuous operation in medical equipment. The electrical part controls the speed and adjusts the stirring intensity through the transmission motor 301 to meet different nursing needs. The entire system has a compact structure, and the gear meshing points are lubricated and sealed to ensure long-term stable operation, thereby improving the overall performance and durability of the device.

[0036] Working Principle: The overall workflow of a decompression irrigation device for gastrointestinal surgical care begins with the injection of cleaning fluid through the inlet pipe 103 at the top of the preheating tank 102. Inside the preheating tank 102, preheating plates 201 fixed to the inner wall first preheat the cleaning fluid. Simultaneously, a servo motor 202 installed at the top of the inner wall of the preheating tank 102 starts, and its output end drives the coaxially arranged drive gear 203 to rotate via a coupling. The drive gear 203 meshes with the first internal gear ring 205 fixedly connected to the inner wall of the limiting rotating frame 204, thereby driving the limiting rotating frame 204 to rotate smoothly on the bottom wall of the preheating tank 102. Several cover plates 206 at the top of the limiting rotating frame 204 rotate synchronously, periodically opening or closing the corresponding through slots at the top of the main tank 101, thereby regulating the batch and orderly flow of the preheated cleaning fluid into the main tank 101.

[0037] After the cleaning fluid enters the main tank 101, the core heating and mixing process begins. The drive motor 301, mounted on top of the main tank 101, operates, driving the drive shaft 302 at its output end to rotate. The drive gear 303, fixedly mounted on the drive shaft 302, rotates accordingly and meshes with several follower gears 306 fixedly mounted on several circumferentially distributed follower shafts 305 inside the main tank 101. This gear transmission stage ensures that all follower shafts 305 are driven synchronously. The equidistantly distributed main arc-shaped stirring rods 304 on the drive shaft 302 and the equidistantly distributed secondary arc-shaped stirring rods 307 on all follower shafts 305 rotate together, performing preliminary, multi-directional stirring of the cleaning fluid.

[0038] Further stirring is accomplished by the transmission frame 308. The transmission frame 308 is rotatably mounted inside the main tank 101 via two symmetrically arranged transmission bearings 310 on its outer circumference. The second internal gear ring 309, fixed to the inner wall of the transmission frame 308, meshes with the aforementioned follower shaft 305 (via the follower gear 306 on it), forming a two-stage gear transmission. Therefore, the rotation of the follower shaft 305 drives the transmission frame 308 and several equidistantly distributed inner arc-shaped stirring rods 311 fixedly connected to its inner wall to rotate together. The inner arc-shaped stirring rods 311 cooperate with the main arc-shaped stirring rod 304 and the secondary arc-shaped stirring rod 307 to form a multi-layered, high-intensity composite stirring flow field from the axis to the circumference, ensuring that the cleaning fluid is heated extremely uniformly and fully exchanges heat with the external heating source (such as an electric heating wire), quickly reaching and maintaining the set temperature.

[0039] Finally, the heated cleaning solution is discharged from the outlet pipe 104 at the bottom of the main tank 101. A water pump 105 installed at the outlet end of the outlet pipe 104 provides the power for delivery, and its internal motor drives an impeller to pump the cleaning solution out. Meanwhile, a pressure reducing valve 106 installed at the tail end of the outlet pipe 104 monitors and adjusts the pressure of the output liquid in real time, ensuring a stable and gentle rinsing process, perfectly suited to the decompression rinsing requirements of gastrointestinal surgery. Thus, the device completes a full, automated workflow from preheating, precise flow control, efficient heating and mixing to constant pressure output.

[0040] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
