Description

Technical Field

[0001] This invention relates to the field of intelligent device technology, and in particular to a replaceable rinsing and suction device and method. Background Technology

[0002] In existing medical surgeries, such as endoscopic surgeries like rigid ureteroscopy, flexible ureteroscopy, percutaneous nephroscopy, cholangioscopy, laparoscopy, hysteroscopy, arthroscopy, and percutaneous endoscopic intervertebral discectomy, as well as surgeries involving the urinary tract, bone and joint spaces, and uterine cavity, it is usually necessary to flush and suction various cavities of the human body.

[0003] CN109621065A discloses a medical intelligent flushing system, including a housing, a flushing fluid bag containing flushing fluid, a drain bag for collecting waste fluid flowing out after flushing hollow organs or thoracic and abdominal cavities, a flushing tube for introducing flushing fluid into hollow organs or thoracic and abdominal cavities, a drain tube, a fluid guiding device, a control circuit board, a flow sensor, a colorimeter, and a power supply. This invention overcomes the shortcomings of existing methods using ordinary infusion tubing for flushing hollow organs or thoracic and abdominal cavities, such as uncontrollable flushing fluid flow rate, inability to monitor drain pipe blockage, and inability to determine the degree of blood cell loss. By monitoring the flow rate and color data of the discharged waste fluid using a flow sensor and colorimeter, it calculates the degree of blood cell loss and controls the flushing fluid introduction speed based on this flow rate data, thus possessing the advantages of controlling the flushing fluid flow rate and real-time monitoring of blood loss.

[0032] Figure 1 This is a schematic diagram of the structure of an alternative flushing and suction device according to one embodiment of the present invention; Figure 2 This is a schematic diagram of the panel structure of an alternative flushing and suction device according to one embodiment of the present invention; please refer to... Figure 1 and Figure 2 ;

[0033] In view of this, the present invention aims to provide a replaceable flushing and suction device, comprising: a washing section 3 and a control section 2; the washing section 3 and the control section 2 are detachably connected; the washing section 3 includes at least a pipe 303, a drive assembly, and a solenoid valve; the pipe 303 is connected to a first interface and a second interface 311 at both ends; the first interface is connected to the solenoid valve, the solenoid valve is connected to an inlet interface 310 and an outlet interface 312, the solenoid valve is used to control the first interface to communicate with the inlet interface 310 or the outlet interface 312; the second interface 311 is connected to a human body cavity through a conduit; the control section 2 includes at least a controller 203, which controls... The device 203 is electrically connected to the drive assembly and the solenoid valve respectively. When the flushing and suction device is used for cavity flushing, the controller 203 controls the solenoid valve to connect the first interface with the liquid inlet 310. The controller 203 controls the drive assembly to draw flushing fluid through the liquid inlet 310 and discharge the flushing fluid through the second interface 311. When the flushing and suction device is used for sludge extraction, the controller 203 controls the solenoid valve to connect the first interface with the liquid outlet 312. The controller 203 controls the drive assembly to draw sludge through the second interface 311 and discharge the sludge through the liquid outlet 312.

[0034] The replaceable flushing and suction device disclosed in this invention includes a washing section 3 and a control section 2; the washing section 3 and the control section 2 are detachably connected; the washing section 3 includes at least a pipe 303, a drive assembly, and a solenoid valve; the control section 2 includes at least a controller 203, which is electrically connected to the drive assembly and the solenoid valve respectively; when the flushing and suction device is used for cavity flushing, the control section 2 controls the washing section 3 to draw flushing fluid through the inlet port 310 and then discharge it through the second port 311; when the flushing and suction device is used for accumulating fluid extraction, the control section 2 controls the washing section 3 to draw accumulating fluid through the second port 311 and discharge it through the outlet port 312, and the flushing section 3 is connected to the control section 2 via the pipe 303, a drive assembly, and a solenoid valve. The combination of 2 enables the functions of fluid aspiration and cavity flushing. Because the rinsing unit 3 and the control unit 2 are detachably connected, only the rinsing unit 3 needs to be replaced when the operation is over. The rinsing unit 3 does not need to be reused to ensure that the rinsing channel is free from contamination, thereby avoiding cross-infection and other situations. At the same time, it integrates two functions of flushing and fluid aspiration, which can be used in more surgical environments. By only replacing the rinsing unit 3, the cost can be saved compared to disposable flushing and suction equipment. Furthermore, by recycling the rinsing unit 3, important components with little or no contact, such as electromagnetic push cylinders and motors, can be uniformly processed to ensure that there is no risk of cross-infection before recycling, further reducing the cost of use.

[0035] In this embodiment, the replaceable flushing and suction device includes a washing section 3 and a control section 2. The washing section 3 and the control section 2 are detachably connected. The detachable connection can be a snap-fit ​​connection. Specifically, the flushing and suction device includes a first housing 313 and a second housing. The first housing 313 and the second housing are combined to obtain the flushing and suction device. The first housing 313 is used to house the washing section 3, and the second housing is used to house the control section 2. Connecting members can be provided at the upper and lower ends of the first housing 313 and the second housing. Specifically, the connecting members can be snap-fits, which are used to fix the first housing 313 and the second housing. During disassembly, simply open the snap-fits, remove the first housing 313 with the washing section 3, and then take out the unused housing with the washing section 3 and assemble it with the second housing to assemble the replaceable flushing and suction device. Specifically, the control unit 2 is equipped with a quick-connect plug 204, and the wash unit 3 is equipped with a cable quick-connect interface 305. The quick-connect plug 204 is located in the control unit 2 and the cable quick-connect interface 305 is located in the wash unit 3. Therefore, when the control unit 2 and the wash unit 3 are connected, the quick-connect plug 204 is plugged into the cable quick-connect interface 305, thereby quickly realizing the electrical connection between the wash unit 3 and the control unit 2, reducing the difficulty of operation and enhancing the user experience.

[0036] The washbasin unit 3 includes at least a pipe 303, a drive assembly, and a solenoid valve. The pipe 303 is for supplying liquid flow and may be U-shaped. Therefore, a first interface and a second interface 311 are connected to both ends of the pipe 303. The first interface is used to connect to the solenoid valve, thereby connecting to either the inlet interface 310 or the outlet interface 312. The solenoid valve, under the control of the controller 203, enables communication between the first interface and the inlet interface 310 or the outlet interface 312. The second interface 311 is used for... The catheter is connected to the human body cavity to extract accumulated fluid or flush the cavity. The inlet port 310, outlet port 312 and second port 311 can be formed on the first housing 313. The inlet port 310 and outlet port 312 are located on the outside of the first housing 313 to facilitate catheter connection. The second port 311 can also be located on the outside of the first housing 313. Furthermore, the second port 311 can be connected to the pipe 303 through the second port connection hole 3061 in the solenoid valve to facilitate the connection of the pressure relief structure. The control unit 2 includes at least a controller 203, which includes at least a control circuit. The controller 203 is electrically connected to the drive assembly and the solenoid valve, respectively, and is used to control the drive assembly and the solenoid valve according to user instructions. When the flushing suction device is used for cavity flushing, the controller 203 controls the solenoid valve to connect the first interface with the inlet interface 310, and the solenoid valve closes the outlet interface 312. The inlet interface 310, the solenoid valve's accommodating cavity, the first interface, the pipe 303, and the second interface 311 form a flushing pipeline. The controller 203 controls the drive assembly. The flushing fluid is drawn through the inlet port 310 and discharged through the outlet pipe via the second port 311. Specifically, when the flushing suction device is used for sludge extraction, the controller 203 controls the solenoid valve to connect the first port with the outlet port 312. The solenoid valve closes the inlet port 310. At this time, the second port 311, the pipe 303, the first port, the accommodating cavity, and the outlet port 312 form an extraction pipe. The controller 203 controls the drive assembly to extract the sludge through the second port 311. After passing through the extraction pipe, the sludge is discharged through the outlet port 312. The drive assembly includes a motor 302 and a pump body 301. The pump body 301 is connected in the pipe 303, and the motor 302 is connected to the pump body 301. The motor 302 provides power to the pump body 301, and the pump body 301 increases the pressure of the liquid in the pipe 303. When flushing the cavity, the motor 302 can rotate forward, thereby driving the pump body 301 to pump the liquid in the pipe 303 out from the second port 311. When extracting accumulated liquid, the motor 302 can rotate in reverse, thereby driving the pump body 301 to pump the liquid in the pipe 303 out from the first port.

Figure 6 This is a schematic diagram of the valve core structure of an alternative flushing suction device according to one embodiment of the present invention; please refer to... Figures 3-6 ;

[0038] In one embodiment, the solenoid valve includes a valve body 306, a valve core 308, and an electromagnetic assembly. One side of the valve body 306 has an inlet port 3067 and an outlet port 3066, respectively for connecting to an inlet interface 310 and an outlet interface 312. The other side of the valve body 306 has a first interface connection hole 3063 for connecting to a first interface. A receiving cavity is formed inside the valve body 306, communicating with the inlet port 3067, the outlet port 3066, and the first interface connection hole 3063. The receiving cavity is used to house the valve core 308. The electromagnetic assembly is connected... On the outside of the valve body 306, a valve core 308 is used to drive the valve core 308 to move within the accommodating cavity. When the electromagnetic component is not energized, the valve core 308 abuts against the first side of the accommodating cavity, and the valve core 308 blocks the liquid outlet 3066 from the accommodating cavity, while the liquid inlet 3067 communicates with the accommodating cavity to connect the first interface and the liquid inlet 310. When the electromagnetic component is energized, the valve core 308 abuts against the second side of the accommodating cavity, and the valve core 308 blocks the liquid inlet 3067 from the accommodating cavity, while the liquid outlet 3066 communicates with the accommodating cavity to connect the first interface and the liquid outlet 312.

[0039] In this embodiment, the electromagnetic component is an electromagnetic push cylinder 307, which is connected to one side of the valve body 306 and forms a receiving cavity with the valve body 306. The receiving cavity is used for connecting the valve core 308. Further, an upper plane is formed in the receiving cavity for positioning the valve core 308 and cooperates with the mounting surface 3082 of the valve core 308. One side of the valve body 306 has an inlet hole 3067 and an outlet hole 3066, which are respectively used for connecting the inlet interface 310 and the outlet interface 312, i.e., the side facing away from the mounting surface 3082. The other side of the valve body 306 has a first interface connection hole 3063 for connecting the first interface, i.e., it is opened on the side facing the mounting surface 3082. The valve body 306 has an internal accommodating cavity, which is connected to the inlet port 3067, the outlet port 3066, and the first interface connection hole 3063. An electromagnetic assembly is connected to the outside of the valve body 306 to drive the valve core 308 to move within the accommodating cavity. When the electromagnetic assembly is not energized, the valve core 308 abuts against the first side of the accommodating cavity. The first side refers to the side facing the valve core 308. The outlet port 3066 is located near the second side, and the inlet port 3067 is located near the first side. Therefore, when the valve core 308 abuts against the first side, the valve core 308... The outlet hole 3066 is blocked from the accommodating cavity, and a gap is formed between the valve core 308 on the second side and the electromagnetic push cylinder 307, so that the inlet hole 3067 is connected to the accommodating cavity, thereby connecting the first interface and the inlet interface 310; similarly, when the electromagnetic component is energized, the valve core 308 abuts against the second side of the accommodating cavity, the second side referring to the side opposite to the valve core push rod 3083. The valve core 308 blocks the inlet hole 3067 from the accommodating cavity, and a gap is formed between the valve core 308 on the first side and the valve body 306, so that the outlet hole 3066 is connected to the accommodating cavity, thereby connecting the first interface and the outlet interface 312. Specifically, the valve core 308 is provided with a guide groove 3081 facing the first interface. The guide groove 3081 can be a rectangular groove. When the valve core 308 abuts against the first side of the accommodating cavity, a first gap channel is formed between the valve core 308 and the second side of the accommodating cavity. The first gap channel and the guide groove 3081 cooperate to form a first channel, which is used to connect the first interface and the liquid inlet 3067. When the valve core 308 abuts against the second side of the accommodating cavity, a second gap channel is formed between the valve core 308 and the first side of the accommodating cavity. The second gap channel and the guide groove 3081 cooperate to form a second channel, which is used to connect the first interface and the liquid outlet 3066. The valve core 308 is connected to a valve core push rod 3083, which is located on the side of the valve core 308 facing the electromagnetic push cylinder 307. A valve core retaining ring 3084 and an elastic element 309 are connected to the valve core push rod 3083. The elastic element 309 can be a spring. The elastic element 309 is installed between the retaining ring and the electromagnetic push cylinder 307 for resetting the valve core 308.When the valve core 308 abuts against the first side of the accommodating cavity, the elastic element 309 can be in a natural state or a slightly compressed state; when the valve core 308 abuts against the second side of the accommodating cavity, the elastic element 309 is in a compressed state. When the electromagnetic push cylinder 307 is not energized, the elastic element 309 returns to its original state, causing the valve core 308 to reset, that is, return to the state of abutting against the first side.

[0040] Furthermore, the valve body 306 also has a second interface connection hole 3061, which passes through the valve body 306. The valve body 306 is a solid part and does not intersect with the accommodating cavity. The second interface connection hole 3061 is used for connection of the second interface 311; a pressure relief channel is formed between the second interface connection hole 3061 and the accommodating cavity. Specifically, the second interface connection hole 3061 may include a pipe connection hole and a discharge hole 3068 at the top. The pipe connection hole is used for pipe embedding, and the size of the discharge hole 3068 is slightly smaller than the size of the pipe connection hole so that the inner diameter of the pipe is consistent with the inner diameter of the discharge hole 3068, so that the water pressure does not change when flowing out, improving the controllability of water pressure, thereby avoiding damage to human body cavities due to excessive pressure. A pressure relief diaphragm mounting groove 3062 is also formed on the valve body 306, which intersects with the pressure relief channel. The pressure relief diaphragm mounting groove 3062 is used for the installation of the pressure relief diaphragm 314, which is used to seal the pressure relief channel. When the pressure in the second interface connection hole 3061 is greater than a specified threshold, the pressure relief diaphragm 314 ruptures, and the second interface connection hole 3061 is connected to the accommodating cavity through the pressure relief channel. The high-pressure flushing fluid will enter the accommodating cavity from the pressure relief channel, thereby achieving the effect of rapid pressure relief and avoiding damage to the body's cavities due to excessive pressure.

[0041] Furthermore, a pressure sensor 304 is also installed in the pipe 303. The pressure sensor 304 is located between the pump body 301 and the second interface 311. The pressure sensor 304 is used to detect the pressure in the pipe 303. The pressure sensor 304 is electrically connected to the controller 203. When the pressure in the pipe 303 exceeds a specified threshold, the controller 203 controls the drive assembly to stop working. This dual-protection system of the pressure sensor 304 and the pressure relief diaphragm 314 effectively prevents the flushing fluid pressure from falling below the specified threshold, thereby protecting the human body cavity from damage caused by high-pressure water flow. The specified threshold corresponds to the data that the human body cavity can withstand; specifically, different data can be set for different cavities.

[0043] In one embodiment, the control unit 2 includes a display panel 1 connected to the controller 203 to display the pressure value detected by the pressure sensor 304.

[0044] In this embodiment, the control unit 2 includes a display panel 1, which may be square. The display panel 1 is electrically connected to the controller 203 to display the pressure value corresponding to the pressure sensor 304. Specifically, the display panel 1 also includes an LCD screen 101, a flushing indicator light 102, a suction indicator light 103, a suction switch 104, a flushing switch 105, and a speed control knob 106.
