Description

Technical Field

[0001] This invention relates to postoperative care equipment technology in urology, specifically to a portable, constant-temperature, dual-channel metering, continuous bladder irrigation device after prostate surgery. Background Technology

[0002] Transurethral resection of the prostate (TURP) is a classic surgical procedure in urology for treating benign prostatic hyperplasia (BPH). Postoperative continuous bladder irrigation is essential. Its core purpose is to promptly remove blood clots and tissue debris from the bladder, maintain the patency of the three-lumen catheter drainage system, and dynamically assess wound bleeding by observing the color, characteristics, flow rate, and velocity of the drainage fluid. This helps prevent postoperative complications such as catheter blockage, bladder spasm, secondary bleeding, and catheter-related urinary tract infections. Continuous bladder irrigation is a crucial nursing step in ensuring patient safety and promoting rapid recovery after TURP; its quality directly affects the surgical outcome and patient prognosis.

[0003] The traditional gravity flushing system commonly used in clinical practice is a temporary assembly of scattered components such as an IV stand, flushing fluid bag, ordinary silicone tubing, T-connector, three-lumen catheter, and drainage bag. The entire process relies on nurses' rounds, manual adjustment of the flushing speed, visual observation of the drainage fluid, and manual recording of intake and output. Its core operational logic is as follows: nurses subjectively judge the bleeding status based on the color and depth of the drainage fluid, adjust the flushing flow rate by changing the height of the IV stand or manually clamping and opening the tubing, regularly check the tubing for patency and for any kinks or dislodgements, and manually record the intake and output using a measuring cup or visual estimation.

[0004] The following publicly available technologies were found through a search:

[0005] 1) A nursing treatment cart disclosed in patent application CN220735495U includes a handcart with a through-hole at one horizontal end. The placement slot is open. Two waste bottle placement holes are symmetrically located on the inner bottom wall of the placement slot. Support blocks are symmetrically installed on both sides of the placement box along its horizontal direction, and the placement box is supported on a limiting rod via the support blocks. A drag bar, L-shaped, is fixedly installed on one side of the handcart. A controller is installed on the handcart below the infusion pole. The controller controls the drip rate of the infusion tube and simultaneously controls the temperature of the infusion solution. For infusion flushing, after a prescribed amount of medication is infused into the bladder, the controller stops the infusion. Then, the other end of a three-way valve is inserted into a waste bottle in the waste bottle placement hole, and the flushing fluid is drained using siphon action. There are two waste bottle placement holes, each with a waste bottle for easy access.

[0006] 2) A bladder irrigation device for urological care, disclosed in patent application CN115869484A, includes a mobile cart with three progressively smaller placement plates arranged from bottom to top. The lower placement plate, from front to back, has a reservoir, a press-type sterilization bottle, a storage box, and a lifting heating frame. A sterilization box is fixed to the middle placement plate, with a squeezing component and a pressurizing component at its upper end. A visual component is located on the front of the sterilization box, and a wristband component is engaged with a locking seat. A displacement computer component is located on the top of the mobile cart, and an irrigation component is located on the lifting heating frame. The irrigation component passes sequentially through the squeezing component and the visual component, and is connected to the reservoir, a negative pressure pump, an irrigation catheter, and the pressurizing component. This invention has a high degree of integration, is easy to operate, can effectively perform bladder irrigation, can administer medication and clear blockages, analyze the color of the irrigation fluid, and determine the irrigation status.

[0007] 3) Announcement No. CN214435658U discloses a bladder irrigation device with a temperature control mechanism. This patent application includes a trolley, a hanger, an IV drip bottle, a shelf, a temperature control device, an infusion tube, a battery pack, a three-way valve, and a drain bottle. The trolley is mechanically connected to the hanger; the IV drip bottle is detachably connected to the hanger via a hook and a hanging hole; the shelf is fixedly connected to the bottom of the hanger; the temperature control device is mounted on the shelf and fixedly connected to the IV drip bottle via the infusion tube; the battery pack is electrically connected to the temperature control device directly below the shelf; the three-way valve is fixedly connected to the side of the temperature control device, with one end being an irrigation pipe and the other a drain pipe, and the drain pipe is fixedly connected to the drain bottle. This utility model device is mounted on a trolley, making the medical process more flexible; the hanger's height can be changed by rotating its shaft; the temperature control device continuously heats the liquid from the inlet to the outlet, and its inner wall is lined with insulation material, improving temperature control efficiency; the temperature control device's display screen provides a more intuitive view of the heated liquid temperature, facilitating timely adjustment.

[0008] While the aforementioned existing technologies optimize certain aspects of bladder irrigation from different perspectives, their functional modules operate independently, and their sensor signals are uncorrelated. Specifically, temperature regulation only achieves constant temperature control of the irrigation fluid, and flow monitoring only displays instantaneous flow; no dynamic coupling relationship is established between them. Post-TURP tube blockage is not caused by a single parameter mutation, but rather by a continuous process resulting from a gradual decrease in drainage flow, a continuously increasing inflow-outflow difference, and a deepening of the drainage fluid color. Only by correlating temperature drift with flow attenuation and simultaneously tracking color changes and the inflow-outflow difference can abnormal trends be identified during the stage when tube blockage is not fully formed and bleeding is slowly increasing. However, in existing technologies, temperature, flow, and color signals are output independently, requiring operators to manually compare and judge the data and provide manual warnings. Therefore, there is an urgent need in this field for a continuous bladder irrigation device capable of establishing a multi-parameter joint judgment logic. Summary of the Invention

[0009] The purpose of this invention is to provide a portable, constant-temperature, dual-channel metering continuous bladder irrigation device after prostate surgery, in order to solve the problem that existing technologies cannot identify abnormal trends in the early stages of duct obstruction.

[0010] To achieve the above objectives, the present invention provides the following technical solution: a portable constant-temperature dual-channel metering continuous bladder irrigation device after prostate surgery, comprising a main support frame and, arranged sequentially from top to bottom along the height direction of the main support frame, an irrigation fluid suspension assembly, a constant-temperature metering control assembly, and a drainage storage assembly, wherein:

[0011] The main support frame is a vertical mobile vehicle frame with a widened base and braked casters at the bottom. The vertical mobile vehicle frame has a push-pull handle fixed at the rear and an integrally formed support frame in the middle.

[0012] The flushing fluid suspension assembly includes a lifting adjustment component mounted on the top of the main support and a suspension bracket mounted on the lifting adjustment component. The suspension bracket is used to hang the flushing fluid bottle, and the flushing pipeline leads out of the bottle mouth of the flushing fluid bottle and extends downward along the main support for flow guidance.

[0013] The constant temperature metering and control component is mounted on the support frame. It includes a main control platform, a constant temperature module, and a dual-channel flow metering module. The main control platform is an integrated control unit comprising a main control unit, a touch screen display, and function operation buttons. An alarm light is installed on the top side of the main control platform. A drainage connection pipeline is located on the main control platform, and constant temperature modules are located on both sides of the main control platform. The dual-channel flow metering module includes an inlet flow sensor and a drainage flow sensor, respectively located on the flushing pipeline and the drainage connection pipeline. Both the inlet flow sensor and the drainage flow sensor are electrically connected to the integrated main control unit.

[0014] The drainage and storage component is a storage compartment located below the main control platform. The interior of the storage compartment is used to store the drainage and collection bags. The top and front of the storage compartment are equipped with cable management covers and cable management buckles, respectively.

[0015] Furthermore, the constant temperature module is used to collect and heat the downflow flushing fluid in real time, so as to keep the flushing fluid constant within the human body flushing temperature range of 35℃~37℃. The constant temperature module includes a support component connected to the side wall of the main control platform and a constant temperature component mounted on the support component.

[0016] Furthermore, the thermostatic component is a chamber-type / jacket-type thermostatic heating structure with a built-in temperature sensor.

[0017] Furthermore, the drainage connection pipeline runs through the inside of the main control platform, and its rear end extends downward to connect and communicate with the drainage collection bag in the drainage storage component.

[0018] Furthermore, the cable management cover is equipped with a cable sealing groove for storing and limiting the flushing and drainage connection cables. In the idle state, the flushing and drainage connection cables are stored inside the cable sealing groove to prevent the cables from being suspended, tangled, or bumped. In the working state, the flushing and drainage connection cables are sealed and connected to the irrigation chamber and drainage chamber of the three-lumen catheter, respectively, forming a fully closed bladder flushing circuit.

[0019] Furthermore, the lifting adjustment component is a vertical sliding locking structure, which can realize stepless adjustment of the height of the suspension bracket and fixed-point locking. By changing the suspension height of the irrigation fluid, the static water pressure of the irrigation can be adjusted to precisely adapt to the postoperative irrigation flow rate and irrigation pressure requirements of different patients.

[0020] Furthermore, both the inlet flow sensor and the outlet flow sensor are tubular Hall effect flow sensors, with the sensor tube sections directly connected in series with the corresponding pipelines.

[0021] Furthermore, a miniature ozone sterilizer is installed inside the main support frame. The output end of the miniature ozone sterilizer is connected to the inside of the storage compartment via a sterilization pipeline. The ozone gas output by the miniature ozone sterilizer creates an ozone antibacterial environment inside the storage compartment, inhibiting bacterial growth at the drainage bag interface, drainage connection pipeline interface, and flushing pipeline interface, thereby reducing the risk of catheter-related urinary tract infections.

[0022] Furthermore, a machine vision module is provided on the bottom side of the cable management cover. This machine vision module includes a miniature CCD image sensor and a supplementary light source fixed to the bottom side of the cable management cover. The detection end of the CCD image sensor faces the drainage collection bag in the storage compartment, and is used to continuously and in real time collect the color of the drainage fluid in the drainage collection bag. The main control unit has a built-in color analysis module, which quantifies and grades the collected drainage fluid color in the RGB / HSV color space, and determines the bleeding status according to the color grade.

[0023] Furthermore, a non-contact infrared temperature sensor is provided on the bottom side of the cable management cover. The detection end of the infrared temperature sensor is arranged facing the surface of the drainage and collection bag to collect the temperature of the outer wall of the drainage and collection bag in real time. When the collected temperature is ≥38.5℃ or the difference between the local temperature of the drainage bag and the current ambient temperature exceeds a preset threshold, the main control unit determines that there is a risk of infection and drives the warning light to output an infection warning signal.

[0024] Compared with existing technologies, the present invention provides a portable constant-temperature dual-channel metering continuous bladder irrigation device after prostate surgery. On the one hand, the constant-temperature module forms a closed-loop constant-temperature control circuit with a built-in temperature sensor and heating element to maintain the irrigation fluid at a constant temperature of 35℃~37℃, which is suitable for the human body. With the help of flow sensors independently set in the irrigation and drainage lines, real-time synchronous metering of the inflow and drainage flow can be achieved, and the difference between inflow and outflow and the balance state can be automatically calculated. On the other hand, the main control platform has a built-in multi-parameter fusion judgment logic to dynamically correlate and analyze the real-time temperature deviation, cumulative inflow, cumulative drainage, and difference between inflow and outflow. At the same time, the machine vision module on the bottom side of the drain cover continuously quantifies and grades the color of the drainage fluid. When the temperature drift is accompanied by a gradual decrease in flow and a gradual deepening of color, and the multiple parameters exceed the joint judgment threshold, the main control unit automatically outputs a graded warning signal and drives the warning light to indicate. The entire device achieves dynamic combined analysis of three parameters: temperature, flow rate, and color. This allows abnormal trends in the early stages of tube blockage and the slow increase in bleeding to be identified and warned at the sensor layer. It also takes into account the maintenance of constant temperature, accurate measurement of inflow and outflow, and early identification of abnormal conditions during the postoperative irrigation process. This solves the problems of isolated output of multiple parameters, the need for manual comprehensive judgment, and delayed warning in existing technologies. Attached Figure Description

[0035] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0036] As attached Figure 1 To be continued Figure 4 As shown:

[0037] Example 1:

[0038] This invention provides a portable constant temperature dual-channel metering continuous bladder irrigation device after prostate surgery, including a main support 1 and an irrigation fluid suspension assembly, a constant temperature metering control assembly, and a drainage storage assembly arranged sequentially from top to bottom along the height direction of the main support 1.

[0039] In one embodiment of the present invention, the main support 1 is a vertical mobile frame with a widened base and brake casters at the bottom. The vertical mobile frame has a push-pull handle 2 fixedly installed at the rear and an integrally formed support frame 3 in the middle.

[0040] In one embodiment of the present invention, the flushing fluid suspension assembly includes a lifting adjustment member 4 mounted on the top of the main support 1 and a suspension bracket 5 mounted on the lifting adjustment member 4. The suspension bracket 5 is used to hang the flushing fluid bottle, and the flushing fluid bottle has a bottle opening leading out of the flushing pipe 6 and extending downward along the main support 1 for flow guidance.

[0041] In one embodiment of the present invention, a constant temperature metering control component is mounted on a support frame 3. The constant temperature metering control component includes a main control platform 7, a constant temperature module 8, and a dual-channel flow metering module. The main control platform 7 is an integrated control unit that integrates a main control unit, a touch screen display, and function operation buttons. A warning light is provided on the top side of the main control platform 7. A drainage connection pipeline 16 is provided on the main control platform 7, and constant temperature modules 8 are provided on both sides of the main control platform 7. The dual-channel flow metering module includes an inlet flow sensor 9 and a drainage flow sensor 10 respectively mounted on the flushing pipeline 6 and the drainage connection pipeline 16. Both the inlet flow sensor 9 and the drainage flow sensor 10 are electrically connected to the integrated main control unit.

[0042] In one embodiment of the present invention, the drainage and storage component is a storage compartment 11 located below the main control platform 7. The storage compartment 11 is used to store the drainage and collection bag 17. The top and front sides of the storage compartment 11 are respectively provided with a cable management cover 12 and a cable management buckle.

[0043] In one embodiment of the present invention, the constant temperature module 8 is used to collect and heat the downflow flushing fluid in real time, so as to maintain the flushing fluid at a constant temperature range of 35°C to 37°C, which is suitable for human body flushing. The constant temperature module 8 includes a support member connected to the side wall of the main control platform 7 and a constant temperature element mounted on the support member. The constant temperature element is a chamber-type / jacket-type constant temperature heating structure with a built-in temperature sensor.

[0044] In one embodiment of the present invention, the drainage connection pipeline 16 is installed inside the main control platform 7, and its rear end extends downward and connects with the drainage collection bag 17 in the drainage storage component.

[0045] In one embodiment of the present invention, the cable management cover plate 12 is provided with a cable sealing groove for receiving and limiting the flushing cable 6 and the drainage connection cable 16. In the idle state, the flushing cable 6 and the drainage connection cable 16 are received and stored inside the cable groove to prevent the cables from being suspended, tangled, or bumped. In the working state, the flushing cable 6 and the drainage connection cable 16 are respectively sealed and connected to the irrigation chamber and the drainage chamber of the three-lumen catheter to form a fully closed bladder flushing circuit.

[0046] In one embodiment of the present invention, the lifting adjustment component 4 is a vertical sliding locking structure, which can realize stepless adjustment and fixed-point locking of the height of the suspension bracket 5. By changing the suspension height of the irrigation fluid, the static water pressure of the irrigation can be adjusted to precisely adapt to the postoperative irrigation flow rate and irrigation pressure requirements of different patients.

[0047] In one embodiment of the present invention, the inlet flow sensor 9 and the drain flow sensor 10 are both tubular Hall flow sensors, and the sensor pipe sections are directly connected in series with the corresponding pipelines.

[0048] Working principle: Example 1 integrates a movable frame, a flushing fluid suspension assembly, a constant temperature metering control assembly, and a drainage storage assembly, all arranged compactly along the height of the main support 1, forming an integrated continuous bladder irrigation device specifically designed for transurethral resection of the prostate (TURP). In use, the device is pushed to the patient's bedside and the brake casters are locked. The flushing fluid bottle is inverted and hung on the suspension support 5. The flushing fluid flows downwards through the flushing pipe 6 into the constant temperature module 8, where it is heated to the set temperature (35℃~37℃) by the constant temperature component. Afterwards, it flows through the inlet flow sensor 9 into the irrigation chamber of the three-lumen catheter, entering the bladder to complete the flushing. The drainage fluid is then drawn out through the drainage chamber of the three-lumen catheter, flows through the drainage flow sensor 10, and then converges into the drainage collection bag 17 via the drainage connection pipe 16. Throughout the irrigation process, the influent flow sensor 9 and the drainage flow sensor 10 collect the influent flow rate and drainage flow rate in real time, respectively. The main control unit automatically calculates the difference between influent and outfluent flow and the balance status. When the difference between influent and outfluent flow continues to increase or the drainage flow rate drops suddenly, it is determined that there is a blockage or bleeding abnormality, and the warning light is activated to output a graded early warning signal. At the same time, the temperature sensor in the constant temperature module 8 feeds back the irrigation fluid temperature to the main control unit in real time, forming a closed-loop constant temperature control. This achieves constant temperature maintenance, accurate measurement of influent and outfluent flow, and real-time early warning of abnormal conditions during the postoperative irrigation process.

[0049] As attached Figure 5 As shown:

[0050] Example 2:

[0051] This embodiment is basically the same as the previous embodiment, except that a mini ozone sterilizer (not shown in the figure) is provided inside the main support 1. The output end of the mini ozone sterilizer is connected to the inside of the storage compartment 11 through the sterilization pipeline 13. The mini ozone sterilizer outputs ozone gas to form an ozone antibacterial environment inside the storage compartment 11, which inhibits the growth of bacteria at the drainage bag interface, the drainage connecting pipeline 16 interface, and the flushing pipeline 6 interface, thereby reducing the risk of catheter-related urinary tract infections.

[0052] Working principle: Since the flushing time after TURP can last for several days, the drainage collection bag 17 and the tubing interface are repeatedly exposed to the air in the ward environment during multiple replacement operations, which poses a risk of retrograde infection by bacteria through the interface. Therefore, in Example 2, a mini ozone sterilizer is added inside the main support 1. The output end of the mini ozone sterilizer is connected to the inside of the storage compartment 11 through the sterilization pipeline 13, and continuously outputs low-concentration ozone gas, so that a micro-positive pressure ozone antibacterial environment is formed inside the storage compartment 11, which effectively inhibits the growth of bacteria at the drainage bag interface and the tubing interface, and reduces the risk of catheter-related urinary tract infection.

[0053] As attached Figure 6 As shown:

[0054] Example 3:

[0055] This embodiment is basically the same as the previous embodiment, except that a machine vision module 14 is provided on the bottom side of the cable management cover 12. The machine vision module 14 includes a miniature CCD image sensor and a supplementary light source fixed to the bottom side of the cable management cover 12. The detection end of the CCD image sensor faces the drainage collection bag 17 in the storage compartment 11 and is used to continuously and in real time collect the color of the drainage fluid in the drainage collection bag 17. The main control unit has a built-in color analysis module, which quantifies and grades the collected drainage fluid color in the RGB / HSV color space and determines the bleeding status according to the color grade.

[0056] Working principle: To avoid the problems of inconsistent assessment standards and difficulty in quantifying and tracking bleeding trends caused by nurses relying solely on visual observation of drainage fluid color and subjective judgment of bleeding status, Example 3 adds a machine vision module 14 to the bottom side of the drainage cover 12. A miniature CCD image sensor, in conjunction with a supplementary light source, continuously and in real time collects the color of the drainage fluid in the drainage collection bag 17. The main control unit has a built-in color analysis module that quantifies and grades the collected colors in the RGB / HSV color space (e.g., 0 to 4 levels), and automatically determines the bleeding status based on the color level. When the color level reaches a preset threshold, it drives the warning light to output a corresponding level of warning signal, providing objective, continuous, and traceable quantitative indicators for bleeding assessment.

[0057] As attached Figure 7 As shown:

[0058] Example 4:

[0059] This embodiment is basically the same as the previous embodiment, except that a non-contact infrared temperature sensor 15 is provided on the bottom side of the cable management cover 12. The detection end of the infrared temperature sensor 15 is arranged facing the surface of the drainage collection bag 17 to collect the temperature of the outer wall of the drainage collection bag 17 in real time. When the collected temperature is ≥38.5℃ or the difference between the local temperature of the drainage bag and the current ambient temperature exceeds a preset threshold, the main control unit determines that there is a risk of infection and drives the warning light to output an infection warning signal.

[0060] Working principle: In Example 4, a non-contact infrared temperature sensor 15 is further added to the bottom side of the drain cover 12 to detect the temperature of the outer wall of the drainage collection bag 17 in real time. When the temperature of the drainage fluid rises abnormally (≥38.5℃) or the local temperature of the drainage bag is significantly higher than the ambient temperature, it indicates that there may be drainage fluid retention, local infection, or bladder inflammation. Based on this, the main control unit determines the risk of infection and drives the warning light to output an infection warning signal, assisting in the early clinical identification of catheter-related urinary tract infections or cystitis, timely collection of drainage fluid for culture, and evaluation of the anti-infection control effect.

[0061] In conjunction with Embodiments 1 to 4 above, the present invention also provides a method for assessing bladder irrigation status based on the fusion of multiple parameters including temperature, flow rate, and color, comprising the following steps:

[0062] 1) After the system starts, the constant temperature module 8 continuously collects the real-time temperature T of the flushing fluid, and the inlet flow sensor 9 and the drainage flow sensor 10 continuously collect the instantaneous inlet flow rate Q. in With the instantaneous flow rate Q of the drainage out The main control unit calculates the difference in inflow and outflow per unit time, ΔQ = Q. in -Q out The cumulative value, and at the same time the machine vision module 14 collects the color of the drainage fluid according to the preset sampling period and quantifies it into color level C;

[0063] 2) The main control unit establishes a real-time monitoring vector with four dimensions: temperature deviation ΔT, inflow / outflow difference ΔQ, drainage flow rate reduction δ, and color grade C. The temperature deviation ΔT is the absolute value of the difference between the real-time temperature T and the set temperature T0, and the drainage flow rate reduction δ is the percentage obtained by dividing the difference between the baseline drainage flow rate and the current drainage flow rate by the baseline drainage flow rate.

[0064] 3) The main control unit has built-in multi-parameter joint judgment logic: when ΔT≤2℃ and ΔQ≤50mL and δ≤20% and C≤1, the system judges it to be in normal flushing state, with no warning output, and the touch screen displays real-time parameters;

[0065] When any of the following combinations of conditions are met, the system determines it as an abnormal trend and outputs a tiered warning:

[0066] a) If δ remains ≥30% and ΔQ continues to increase to ≥100mL, while C ≥2, it is determined to be a case of increased bleeding during tube blockage, triggering a yellow alert;

[0067] b) If ΔQ ≥ 150 mL and C ≥ 3, and the drainage flow rate does not decrease significantly, it is considered an increase in active bleeding, triggering a red alert;

[0068] c) If ΔT≥3℃ and ΔQ≥80mL, it is determined to be an abnormal temperature combined with flow imbalance, triggering a yellow warning;

[0069] d) C showed a continuous upward trend and δ increased successively in three consecutive sampling periods, which was judged as a trend of worsening bleeding combined with tube blockage, triggering a red alert;

[0070] e) If the drainage flow rate drops by ≥50% and ΔQ≥200mL, it is determined to be acute tube blockage, triggering a red emergency warning;

[0071] 4) The warning signal is output synchronously through the warning light and the touch screen. At the same time, all monitoring parameters and warning events are automatically stored in the main control unit to generate a traceable postoperative irrigation record.

[0072] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
