[0019] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.
[0020] Example 1, as Figure 1 As shown, a postoperative irrigation device for urological surgery includes a fixing component 1 and a saline storage bag 2. A catheter 21 is provided at the middle of the front end of the saline storage bag 2. A sensing component 3 is provided on one side of the outer surface of the catheter 21. An auxiliary component 6 is symmetrically arranged above the fixing component 1. A movable component 4 is fixedly connected to the left side above the fixing component 1. A clamping component 5 is provided on the right side of the movable component 4.
[0021] The aforementioned fixing component 1 is fixed to the hospital bed and the bedside table using existing C-shaped clips.
[0022] The catheters described in this application are all three-lumen catheters commonly used in the prior art.
[0023] After urological surgery, during the postoperative irrigation process, the fixation component 1 is first fixed to prevent the catheter from bending due to patient movement or accidental contact during irrigation. Then, the end of the saline storage bag 2 with the interface is fixed above the fixation component 1 using two auxiliary components 6. Next, the rear end of the saline storage bag 2 is fixed using the clamping component 5. After connecting the catheter 21 and the saline storage bag 2, the catheter 21 is connected to the irrigation port of the catheter through the Luer connector in the prior art.
[0024] Then the catheter is connected with the drainage bag, which is convenient for observing and collecting the washing liquid during the washing process.
[0025] The moving assembly 4 is actuated to slowly wind the rear end of the normal saline storage bag 2 in cooperation with the clamping assembly 5, and the normal saline in the normal saline storage bag 2 is slowly squeezed into the catheter through the catheter 21 at the same time. When the moving assembly 4 winds the rear end of the normal saline storage bag 2 in cooperation with the clamping assembly 5, the moving assembly 4 and the fixed assembly 1 are cooperated to slowly move forward at the same time. Further, if the catheter is blocked by blood clots or tissues during the washing process, the pressure of the normal saline in the catheter and the catheter 21 changes, which is sensitively detected by the sensing assembly 3 and quickly fed back to the moving assembly 4, so that the winding of the moving assembly 4 and the clamping assembly 5 is immediately stopped, thereby avoiding the risk of complications caused by improper washing.
[0026] Similarly, when the two auxiliary assemblies 6 clamp the front end of the normal saline storage bag 2 in cooperation, the thickness of the normal saline storage bag 2 is self-adapted to adjust, so that the two auxiliary assemblies 6 always clamp the front end of the normal saline storage bag 2, thereby avoiding the situation that the normal saline storage bag 2 is loosened and pulls the catheter when the moving assembly 4 and the clamping assembly 5 are cooperated to wind the normal saline storage bag 2.
[0027] The pressure of the normal saline in the normal saline storage bag 2 squeezed by the moving assembly 4 and the clamping assembly 5 can be adjusted according to the human body adaptation to adjust the winding speed and the washing pressure.
[0028] During the operation of the embodiment, the sensing assembly 3 can sensitively detect the pressure change of the normal saline in the catheter and the catheter 21, and when the catheter is blocked by blood clots or tissues, the pressure change is quickly captured and fed back to the moving assembly 4, so that the winding action of the moving assembly 4 and the clamping assembly 5 is immediately stopped, thereby avoiding the abnormal increase of the washing pressure caused by the blockage. Meanwhile, the speed of the moving assembly 4 and the clamping assembly 5 winding the normal saline storage bag 2 can be adjusted according to the human body adaptation to adjust the washing pressure, and the two auxiliary assemblies 6 are cooperated to avoid the situation that the normal saline storage bag 2 is loosened and pulls the catheter during the washing process, thereby ensuring the continuity of the washing process.
[0029] In the second embodiment, the normal saline is slowly and stably outputted for washing according to the patient condition during the washing process, and the sensing and feedback effect of stopping the delivery of the normal saline is realized at the moment when the catheter is blocked.
[0030] Referring to Figure 2 and Figure 3The fixed assembly 1 comprises a fixed seat one 11 and a fixed seat two 13, the upper end of the fixed seat one 11 is rotationally connected with a support frame 12, and the upper end of the left side of the fixed seat two 13 is fixedly connected with a guide rail 14.
[0031] The fixed seat one 11 is fixedly connected with the side of the bed through a C-shaped clamp in the prior art, and the fixed seat two 13 is fixedly connected with the side table of the bed through a C-shaped clamp in the prior art.
[0032] When flushing, the support frame 12 is used to assist in supporting the bifurcated part of the catheter, so as to avoid that the catheter is bent or squeezed due to the patient turning over or accidental touch during the flushing process, and thus the judgment during the flushing process is affected.
[0033] Referring to Figure 11 The auxiliary assembly 6 comprises a fixed plate three 67 fixedly connected with the upper end of the fixed seat two 13, two springs two 68 fixedly connected with the right end of the fixed plate three 67 in a symmetrical manner, a vertical plate 66 fixedly connected with the right end of the two springs two 68, a guide rod 69 slidably connected with the lower end of the vertical plate 66, the guide rod 69 being fixedly connected with the upper end of the fixed seat two 13, and a moving block 61 fixedly connected with the front end of the vertical plate 66.
[0034] After the fixed seat one 11 and the fixed seat two 13 are fixed respectively, a brand new physiological saline storage bag 2 is placed on the upper end of the fixed seat two 13, then the vertical plate 66 is pushed to slide leftwards along the guide rod 69, and in the process of sliding leftwards, the moving block 61 is driven to move while cooperating with the fixed plate three 67 to squeeze the two springs two 68.
[0035] Referring to Figure 10 The front end of the right side of the moving block 61 is rotationally connected with a rotating plate one 64, the front end of the left side of the moving block 61 is rotationally connected with a rotating plate two 65, the upper side of the rear end of the rotating plate one 64 and the rotating plate two 65 is rotationally connected with a fixed plate one 62, the lower end of the fixed plate one 62 is fixedly connected with a silica gel sheet one 621, the middle part of the rear end of the rotating plate two 65 is rotationally connected with a fixed plate two 63, and the upper end of the fixed plate two 63 is fixedly connected with a silica gel sheet two 631.
[0036] The fixed plate one 62 is fixedly connected with the upper end of the fixed seat two 13.
[0037] In the process of moving block 61 being driven by vertical plate 66 to move left, moving block 61 drives the lower end of rotating plate one 64 and rotating plate two 65 to move left, thereby realizing rotating plate one 64 and rotating plate two 65 rotating counterclockwise by a distance respectively around the position of fixed plate one 62 rotating connection, in the process of rotating plate two 65 rotating counterclockwise, it drives fixed plate two 63 to move simultaneously, thereby fixed plate two 63 drives silica gel sheet two 631 and silica gel sheet one 621 to separate, when the distance between silica gel sheet one 621 and silica gel sheet two 631 exceeds the thickness of the front end of normal saline storage bag 2, the front end of normal saline storage bag 2 is placed between silica gel sheet one 621 and silica gel sheet two 631, then silica gel sheet two 631 drives fixed plate two 63 and silica gel sheet one 621 to clamp the front end of normal saline storage bag 2, at this time rotating plate two 65 and rotating plate one 64 and moving block 61 cannot continue to move, thereby at this time two springs two 68 are in compressed state. At the same time, due to silica gel sheet two 631 and silica gel sheet one 621 clamping the front end of normal saline storage bag 2, through the limiting of silica gel sheet two 631 and fixed plate two 63 to rotating plate two 65, the position of moving block 61 and vertical plate 66 remains unchanged.
[0038] In the process of flushing, the normal saline in normal saline storage bag 2 gradually reduces, when the thickness of normal saline storage bag 2 as a whole becomes thin, at this time a gap is generated between the front end of normal saline storage bag 2 and silica gel sheet one 621, thereby silica gel sheet two 631 can no longer limit the position of fixed plate two 63 and rotating plate two 65; thereby the two springs two 68 being compressed push vertical plate 66 to the right, at the same time vertical plate 66 drives moving block 61 to move right by a distance, in the process of moving block 61 moving right, it drives the lower end of rotating plate one 64 and rotating plate two 65 to move right, thereby rotating plate two 65 drives fixed plate two 63 and silica gel sheet two 631 to rotate clockwise by a certain angle, until silica gel sheet two 631 and silica gel sheet one 621 cooperate to clamp the front end of normal saline storage bag 2 again, at this time rotating plate two 65 and moving block 61 and vertical plate 66 no longer move, two springs two 68 are still in compressed state; Further, in the process of flushing, with the flow of normal saline in normal saline storage bag 2, silica gel sheet two 631 and silica gel sheet one 621 can adapt to the thickness of normal saline storage bag 2, always clamp the front end of normal saline storage bag 2, avoiding the front end of normal saline storage bag 2 moving in the process of flushing to drag catheter 21 and urinary catheter, causing unnecessary harm to the patient.
[0039] The clamping position of silica gel sheet two 631 and silica gel sheet one 621 is still a distance from the interface of the middle part of the front end of normal saline storage bag 2, that is, it does not cover the interface position.
[0040] Referring to Figure 8 and Figure 9The clamping assembly 5 comprises a U-shaped plate 51, a rectangular rod one 52 is fixedly connected to the lower middle part of the vertical part of the U-shaped plate 51, a circular groove 521 is formed in the right upper end of the rectangular rod one 52, a baffle 55 is fixedly connected to the right upper end of the rectangular rod one 52, an arc-shaped groove 551 is formed in the upper middle part of the baffle 55, and a rectangular rod two 53 is rotatably connected to the upper middle part of the vertical part of the U-shaped plate 51.
[0041] Further, after the front end of the physiological saline storage bag 2 is fixed by cooperating with the same-side silica gel sheet two 631 and the silica gel sheet one 621, the rear end of the physiological saline storage bag 2 is placed on the upper end of the rectangular rod one 52, then the rectangular rod two 53 is rotated, and the lower end of the rectangular rod two 53 is tightly attached to the upper end of the physiological saline storage bag 2; Referring to Figure 9 The right upper end of the rectangular rod one 52 is slidably connected with an L-shaped roller 54, the lower end of the rectangular rod one 52 is fixedly connected with a spring one 56, the lower end of the spring one 56 is fixedly connected with a rectangular plate 58, the middle part of the rectangular plate 58 is fixedly connected with the outer surface of the L-shaped roller 54, and the outer surface of the L-shaped roller 54 below the rectangular plate 58 is fixedly connected with a limiting roller 57.
[0042] Further, the vertical part of the L-shaped roller 54 is pressed downward, so that the lower surface of the L-shaped roller 54 is tightly attached to the inner surface of the circular groove 521, at this time, the spring one 56 is in the original length state, and the two limiting rollers 57 and the baffle 55 are in the parallel position, at this time, the L-shaped roller 54 limits the distance between the rectangular rod two 53 and the rectangular rod one 52 through the circular groove 521, so that the rectangular rod two 53 and the rectangular rod one 52 clamp the rear end of the physiological saline storage bag 2.
[0043] Referring to Figure 7 The moving assembly 4 comprises a control module 41 fixedly connected to the upper end of the fixed seat two 13, the control module 41 is electrically connected with a micro direct current motor 42, the outer surface of the lower part of the micro direct current motor 42 is fixedly connected with a rectangular block 43, the lower end of the rectangular block 43 is slidably connected with the upper surface of the fixed seat two 13, the output end of the micro direct current motor 42 is fixedly connected with a gear 44, the outer surface of the gear 44 is engaged with a rack 45, and the output end of the micro direct current motor 42 is fixedly connected with the U-shaped plate 51.
[0044] When the rear end of the physiological saline storage bag 2 is fixed by the cooperation of the rectangular rod one 52 and the rectangular rod two 53, and the front end of the physiological saline storage bag 2 is clamped by the silica gel sheet two 631 and the silica gel sheet one 621, the control module 41 is used to control the micro DC motor 42, and then the output end of the micro DC motor 42 rotates, and in the counterclockwise rotation process of the output end of the micro DC motor 42, the gear 44 and the U-shaped plate 51 are driven to rotate counterclockwise at the same time, and then in the rotation process of the U-shaped plate 51, the rear end of the physiological saline storage bag 2 and the rectangular rod one 52 and the rectangular rod two 53 are driven to wind forward at the same time, and in the winding process, the physiological saline in the physiological saline storage bag 2 is slowly and uniformly extruded through the inside of the catheter 21 and the catheter flushing port into the inside of the catheter, which further ensures that the physiological saline enters the bladder at a constant flow rate, achieves a more uniform and effective flushing effect, and better flushes out the blood clots and debris, and at the same time, medical staff need to observe the color of the flushing liquid in real time to judge the patient's condition.
[0045] When the rear end of the physiological saline storage bag 2 is wound by the micro DC motor 42 to drive the U-shaped plate 51 and the rectangular rod one 52 and the rectangular rod two 53, and the physiological saline is extruded, the rotation speed of the output end of the micro DC motor 42 can be pre-adjusted by the control of the control module 41, so that the extrusion pressure of the physiological saline is within the bearing range of the patient.
[0046] Similarly, while the output end of the micro DC motor 42 drives the gear 44 and the U-shaped plate 51 to rotate, the gear 44 and the rack 45 cooperate to drive the micro DC motor 42 and the U-shaped plate 51 to move forward during the rotation of the gear 44, and then the rectangular block 43 will slide forward along the upper surface of the fixed seat two 13, which further realizes the extrusion of the physiological saline in the physiological saline storage bag 2 while winding the rear end of the physiological saline storage bag 2, and cooperates with the silica gel sheet two 631 and the silica gel sheet one 621 to prevent displacement of the physiological saline storage bag 2 during flushing, and continuous winding and extrusion of the physiological saline in the physiological saline storage bag 2 for flushing can effectively prevent the formation of blood clots and blockage of early accumulation.
[0047] After the flushing is completed, the vertical plate 66 is pushed to the left, and then the two springs two 68 are extruded, the moving block 61 is driven to move left by the vertical plate 66, the fixed plate two 63 and the silica gel sheet two 631 are separated from the silica gel sheet one 621 and the fixed plate one 62 through the cooperation of the rotating plate two 65 and the rotating plate one 64, and then the locking of the front end of the physiological saline storage bag 2 by the silica gel sheet two 631 and the silica gel sheet one 621 is released. Next, pull the L-shaped roller 54 upward. At this time, the spring 56 is compressed. When the lower arc surface of the L-shaped roller 54 is separated from the inner surface of the circular groove 521 and continues to rise, rotate the L-shaped roller 54 so that the two limiting rollers 57 are in a state perpendicular to the baffle 55. Then move the L-shaped roller 54 downward. During the descent of the L-shaped roller 54, it drives the two limiting rollers 57 to descend. At this time, the limiting roller 57 on the left side is in close contact with the inner surface of the arc groove 551. Through the cooperation of the baffle 55 and the arc groove 551, the limiting roller 57 and the L-shaped roller 54 stop descending. At the same time, the L-shaped roller 54 and the inner surface of the circular groove 521 separate. Then, the saline storage bag 2 can be taken out and placed in the medical waste for disposal.
[0048] See Figure 4 , Figure 5 The sensing component 3 includes a silicone tube 31 fixedly connected to one side of the outer surface of the conduit 21. A balance hole 311 is provided on the upper part of the outer surface of the silicone tube 31. A pressure sensing diaphragm 32 is fixedly connected to the outer surface of the conduit 21 on the inner surface of the silicone tube 31. A push rod 33 is fixedly connected to the left arc surface of the pressure sensing diaphragm 32. A pressure sensor 34 is fixedly connected to the inner surface of the silicone tube 31. The control module 41 is electrically connected to the pressure sensor 34.
[0049] The aforementioned control module 41 is a conventional configuration in the prior art, specifically composed of a signal conditioning circuit, a core controller, a hardware comparator, a motor drive circuit, and a power management unit, wherein: The signal conditioning circuit is used to receive and process raw signals from sensors triggered by pressure-sensitive diaphragms, such as strain gauges, microswitches, and capacitive sensors. The core controller is the decision-making center of the system. It receives and processes the pressure signal, executes preset logical judgments, issues motor control commands, and may manage other functions such as alarms and status indications. The hardware comparator provides a faster-responding hardware-level overvoltage protection failure safety mechanism that is independent of MCU software; The motor drive circuit receives a weak control signal from a hardware comparator and outputs a drive signal with sufficient power and current to control the start, stop, direction, and speed of the DC motor. The power management unit provides a stable and clean DC operating voltage for the entire control module 41 and the motor.
[0050] During the entire operation of the device, the pressure sensor 34 works in conjunction with the control module 41. The pressure sensor 34 converts the detected pressure into an electrical signal and sends it to the control module 41, which in turn controls the operation of the micro DC motor 42. The detailed working principle of the control module 41 will not be elaborated in this solution.
[0051] The pressure sensor 34 is a conventional design in the prior art, which can quickly detect pressure changes, convert the pressure change into an electrical signal, and transmit the signal to the control module 41.
[0052] Referring to Figure 6 During the flushing process, the physiological saline in the physiological saline storage bag 2 enters the catheter through the inner surface of the catheter 21, at this time, the pressure sensing diaphragm 32 is in a slightly deformed state, and the arc surface of the push rod 33 is in contact with the right end of the pressure sensor 34; During the flushing process, if blood clots or tissue block the catheter, the liquid pressure in the catheter 21 will increase rapidly, which will cause the pressure sensing diaphragm 32 to deform to a greater extent, thereby causing the push rod 33 to move a small distance to the left, and the push rod 33 will press the pressure sensor 34, and the pressure sensor 34 will convert the received pressure change into an electrical signal and transmit it to the control module 41, and the control module 41 will automatically control the micro DC motor 42 to stop running and stop pressing the physiological saline. Then the medical staff releases the locking of the catheter 21 and the catheter, and manually sucks out the blockage, and then continues to flush.
[0053] Therefore, the present application uses the structures of the second silicone sheet 631, the first silicone sheet 621, the moving block 61, and the vertical plate 66 to adapt to the thickness change of the physiological saline storage bag 2, so that the front end of the physiological saline storage bag 2 is always in a clamped and fixed state, and the structures of the micro DC motor 42 and the U-shaped plate 51 are used to wind the rear end of the physiological saline storage bag 2, so that the physiological saline is output at a slow and uniform speed to ensure that the flushing liquid uniformly covers the inner wall of the bladder and the surgical wound, and more efficiently flushes out blood clots, tissue debris, and other foreign matter. At the same time, through the cooperation of the pressure sensing diaphragm 32, the push rod 33, the pressure sensor 34, and the control module 41, the pressure change in the catheter 21 can be accurately captured, and when the catheter is blocked by blood clots or tissue, the physiological saline in the physiological saline storage bag 2 can be quickly stopped, thereby avoiding high pressure impact on the bladder or urethral mucosa, effectively preventing serious complications such as urethral tear and bladder rupture, and using the control module 41 to cooperate with the micro DC motor 42 to adjust the winding speed of the physiological saline storage bag 2, the physiological saline extrusion pressure is accurately controlled, and the discomfort of the patient after the operation is reduced.
[0054] It should be particularly noted that the specific installation method of the micro DC motor 42, the connection method of the circuit, and the control method all belong to conventional designs, and the present application will not be described in detail.
