Description

Technical Field

[0001] This invention relates to the field of medical auxiliary device technology, specifically a urological stone flushing device. Background Technology

[0002] Urinary tract stones, also known as urinary calculi, refer to a group of diseases caused by various factors that result in stones in the ureter, kidneys, bladder, urethra, and other parts of the body. When the urinary tract stones are small, treatment is usually not required, as the stones will gradually pass through the urine. If the stones are large or fail to pass through the urine in time, minimally invasive surgery and subsequent irrigation are necessary for cleaning.

[0003] Patent application CN202110364049.5 discloses a stone flushing device for urology, including a housing with a connecting pipe at the bottom and a flushing frame connected to the outside of the connecting pipe. Multiple liquid storage chambers are located inside the housing, with inlets on the outside of each chamber. A squeezing chamber is located at the bottom of each storage chamber, and a squeezing device is slidably connected to the squeezing chamber inside each squeezing chamber. This invention allows flushing fluid from the corresponding squeezing chamber to enter a mixing tube through an input pipe by pressing one of the levers, under the pushing force of a movable plug. Simultaneous pressing of two or more levers allows flushing fluid from different squeezing chambers to enter the mixing tube and the flushing chamber, mixing them together. The flushing then flushes the stones inside the patient's body through the flushing tube. The flow rate and velocity of the flushing fluid in the flushing tube can be controlled by the number of levers pressed. However, this patent also has the problem that the water used for flushing needs to be filtered and purified to prevent bacterial infection. Therefore, a urological stone flushing device with a water purification function is necessary. Summary of the Invention

[0004] The purpose of this invention is to provide a urological stone irrigation device to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a urological stone irrigation device, comprising an irrigation end shell, a filter tube fixedly connected to the right side of the irrigation end shell, a protective cover fixedly connected to the rear side of the irrigation end shell, a connecting pipe fixedly connected to the inner front side of the irrigation end shell, a circulating filter tube installed on the left side of the irrigation end shell, an input pipe fixedly connected to the rear side of the circulating filter tube, a connecting pipe fixedly connected to the rear side of the filter tube, a sealing ring fixedly connected to the front side of the filter tube, a filter membrane fixedly connected inside the filter tube, the sealing ring fixedly connected to the connecting pipe, a motor fixedly connected to the inner side of the irrigation end shell, and the filter tube connected to the connecting pipe via a connecting pipe. The pipe and the circulating filter pipe form a connected structure. Through this structure, the water used to flush stones is connected to the connecting pipe through an external pipe, allowing the liquid to enter the connecting pipe through the external pipe and then into the filter pipe. The liquid is filtered by the filter material inside the filter pipe. Different filter materials inside the filter pipe are separated by a filter membrane, which filters out small molecules in the water. This deep filtration process prevents bacteria from remaining in the water and causing infection. At the same time, the liquid transported in the filter pipe is transported to the connecting pipe through a sealing ring and then enters the circulating filter pipe. It is further filtered by the internal structure of the circulating filter pipe, thereby improving the filtration effect.

[0006] According to the above technical solution, a liquid supply regulating device is provided at the end of the motor output shaft. The liquid supply regulating device includes a short shaft connecting plate, a pump body, a water tank, a water control end shell, a water control groove plate, a connecting valve pipe, a valve ring, a connecting valve disc, and a liquid diaphragm plate. The short shaft connecting plate is fixedly connected to the end of the motor output shaft. The pump body is fixedly connected to the top of the flushing end shell. The water tank is fixedly connected below the pump body. The water control end shell is fixedly connected below the water tank. The water control groove plate is fixedly connected to the inner wall of the water control end shell. The connecting valve pipe is slidably connected to the inner side of the water control groove plate. The liquid diaphragm plate is fixedly connected to the end side of the connecting valve pipe. The valve ring is fixedly connected to the side of the liquid diaphragm plate. The connecting valve disc is rotatably connected to the inner side of the valve ring. A notch is provided on the side of the liquid diaphragm plate. A liquid passage groove is provided on the side of the connecting valve disc. A semi-circular sealing groove extends to the left side from the notch of the liquid diaphragm plate. With the above structure, when the motor drives the short shaft connecting plate through the output shaft... The rotating shaft-connecting disc drives the pump body, drawing liquid from the circulating filter tube into the pump body through the input pipe. The liquid then enters the water tank through the bottom-connected pipe. Water from the tank directly enters the bottom-connected control end housing. At this point, the valve ring pulls the diaphragm plate, causing it to slide against the inside of the control end housing. This movement moves the fixed connecting valve pipe, which then slides against the control end housing. When the connecting valve pipe disengages from the inner wall of the control end housing, the upper end of the control end housing connects to the inner side of the diaphragm plate through the connecting valve pipe. As the connecting valve pipe moves further from the inner wall of the control end housing, the diaphragm plate slides with it, increasing the space between the diaphragm plate and the inner wall of the control end housing, thus controlling the flow rate. Simultaneously, rotating the connecting valve disc allows the liquid passage groove on its side to face or move away from the notch in the diaphragm plate, quickly controlling the liquid delivery and stopping.

[0007] According to the above technical solution, a circulating liquid pushing device is provided at the inner bottom end of the short shaft connecting disc. The circulating liquid pushing device includes an infusion pipe, a hot circulation pipe, an air-blowing end shell, a push rod, a piston, a regulating pipe, an inner through pipe, and an internal horizontal pipe. The infusion pipe is fixedly connected to the side of the water-control end shell, the hot circulation pipe is wound around the outside of the infusion pipe, the air-blowing end shell is located on the outside of the hot circulation pipe, the push rod is rotatably connected to the inner side of the short shaft connecting disc, the piston is fixedly connected to the side of the air-blowing end shell, and the regulating pipe is fixedly connected to the top inner wall of the air-blowing end shell. The inner tube is slidably connected to the inner side of the control tube, and the built-in horizontal tube is fixedly connected to the inner side of the inner tube. The piston is slidably connected to the end of the push rod. The control tube is connected to the hot circulation tube through a pipe. The lower half of the hot circulation tube is spirally wound around the outside of the infusion tube, and the upper half of the hot circulation tube extends into the gas-blowing end shell. A one-way valve is provided on the bottom side of the piston. With the above structure, when the short shaft connecting disc rotates, it will cause the short shaft connecting disc to drive the push rod to push the piston to be pressurized, causing the piston to draw air from the bottom. The gas delivery is controlled by the control tube connected to the side of the piston. When the inner tube inside the control tube slides downwards, aligning the outer hole at the bottom of the inner tube with the side of the piston, the gas inside the piston enters through the side hole of the inner tube and exits through the top hole to the inside of the inflator shell. This causes air to accumulate inside the inflator shell, increasing the air pressure. The air pressure inside the inflator shell can be used to supply air to patients who cannot turn over for extended periods during treatment. The external airbag is connected to the tube and the inflator shell, allowing the inflator shell to supply air to the airbag, thus inflating the muscles at the base of the body with the airbag when the patient is lying down. The passive movement promotes blood circulation. Simultaneously, as the inner tube slides downward, aligning the inner horizontal tube with the side of the piston, the air supplied by the piston enters the tube connected to the outside of the control tube through the inner horizontal tube, and then is delivered to the hot circulation tube. This allows the gas to drive the air circulation within the hot circulation tube, and the hot circulation tube is heated when energized. This, combined with the air circulation within the hot circulation tube, enhances the heating effect of the hot circulation tube on the infusion tubing. By heating the liquid, the body's discomfort from liquids below body temperature is reduced.

[0008] According to the above technical solution, an anti-backflow device is provided at the end of the infusion tube. The anti-backflow device includes a one-way tube, a cylindrical block, a fixed cylindrical plate, a liquid passage hole, and an output end. The one-way tube is fixedly connected to the end of the infusion tube, the fixed cylindrical plate is fixedly connected to the inner side of the one-way tube, the cylindrical block is slidably connected to the inner side of the fixed cylindrical plate, the liquid passage hole is opened on the upper surface of the cylindrical block, and the output end is fixedly connected to the side of the one-way tube. The cross-sectional diameters at both ends of the cylindrical block are larger than the cross-sectional diameter at the middle. An inner through groove is opened on one side of the cylindrical block, and the inner through groove is connected to... The liquid passage holes are interconnected. Through the above structure, when liquid is transferred to the one-way tube through the infusion tube, the liquid in the one-way tube will enter through the cylinder block. The liquid pressure will push the cylinder block outward and squeeze the spring, so that the liquid passage hole on the side of the cylinder block passes through the solid cylinder plate, allowing the liquid inside the cylinder block to flow out through the liquid passage hole and be output through the output end. When the liquid flows back at the output end, the side of the cylinder block near the output end is compressed, and with the spring force, the cylinder block moves to push the liquid passage hole past the solid cylinder plate, which plays a role in sealing and connecting, thereby effectively preventing liquid backflow.

[0009] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0010] This invention, by incorporating a connecting pipe, a sealing ring, a motor, a circulating filter pipe, and a filter membrane, deeply purifies water through filtration, preventing bacterial contamination. Simultaneously, the liquid transported within the filter pipe is conveyed to the connecting pipe via the sealing ring, and then enters the circulating filter pipe through the connecting pipe, where it undergoes further filtration through the internal structure of the circulating filter pipe, thereby enhancing the filtration effect.

[0011] This invention, by setting up a short shaft connecting plate, pump body, water tank, water control end shell, water control groove plate, connecting valve pipe, valve ring, connecting valve disc, and liquid diaphragm, increases the space between the liquid diaphragm and the inner wall of the water control end shell, and plays a role in controlling the flow rate. At the same time, when the connecting valve disc is rotated, the liquid passage square groove opened on the side of the connecting valve disc faces the notch of the liquid diaphragm or moves away from the notch of the liquid diaphragm, thereby quickly controlling the liquid delivery and stopping.

[0012] This invention, comprising an infusion tube, a hot circulation tube, an inflatable end shell, a push rod, a piston, a control tube, and an inner tube, can be used to supply air to patients who cannot turn over for extended periods during treatment. An external airbag is connected to the tube and the inflatable end shell, allowing the inflatable end shell to supply air to the airbag. This allows the muscles at the base of the patient's body to move passively as the airbag inflates, thus promoting blood circulation. Simultaneously, the air circulation within the hot circulation tube enhances the heating effect on the infusion tube, reducing discomfort caused by liquids below body temperature.

[0013] This invention comprises a one-way tube, a cylindrical block, a solid cylindrical plate, a liquid passage hole, and an output end. The outer side of the cylindrical block near the output end is pressurized, and with the help of spring force, the cylindrical block moves to push the liquid passage hole past the solid cylindrical plate, thereby achieving a sealing and connecting effect and effectively preventing liquid backflow.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Example 1

[0025] Please see Figure 1-4 This invention provides a technical solution: a urological stone irrigation device, comprising an irrigation end shell 1, a filter tube 2 fixedly connected to the right side of the irrigation end shell 1, a protective cover 3 fixedly connected to the rear side of the irrigation end shell 1, a connecting tube 4 fixedly connected to the inner front end of the irrigation end shell 1, a circulation filter tube 12 installed on the left side of the irrigation end shell 1, an input tube 7 fixedly connected to the rear side of the circulation filter tube 12, a connecting tube 9 fixedly connected to the rear side of the filter tube 2, a sealing ring 10 fixedly connected to the front side of the filter tube 2, and a filter membrane 13 fixedly connected inside the filter tube 2. The sealing ring 10 and the connecting tube 4 are connected together. A motor 11 is fixedly connected to the inner side of the flushing end shell 1. The filter tube 2 is connected to the circulation filter tube 12 through the connecting pipe 4. Through the above structure, the filter material inside the filter tube 2 is used for filtration. Different filter materials inside the filter tube 2 are separated by the filter membrane 13. The filter membrane 13 filters out small molecules in the water. The water is deeply purified by filtration to prevent bacteria from remaining in the water and causing infection. The liquid connecting pipe 4 enters the circulation filter tube 12 and is further filtered through the internal structure of the circulation filter tube 12, thereby improving the filtration effect.

[0026] A liquid supply regulating device 5 is provided at the end of the output shaft of motor 11. The liquid supply regulating device 5 includes a short shaft connecting plate 51, a pump body 52, a water tank 53, a water control end shell 54, a water control trough plate 55, a connecting valve pipe 56, a valve ring 57, a connecting valve disc 58, and a liquid diaphragm 59. The short shaft connecting plate 51 is fixedly connected to the end of the output shaft of motor 11. The pump body 52 is fixedly connected to the top of the flushing end shell 1. The water tank 53 is fixedly connected to the bottom of the pump body 52. ​​The water control end shell 54 is fixedly connected to the bottom of the water tank 53. The water control trough plate 55 is fixedly connected to the inner wall of the water control end shell 54. The connecting valve pipe 56 is slidably connected to the inner side of the water control trough plate 55. The liquid diaphragm 59 is fixedly connected to the end side of the connecting valve pipe 56. The valve ring 57 is fixedly connected to the end of the connecting valve pipe 56. Connected to the side of the liquid separator 59, the connecting valve disc 58 is rotatably connected to the inner side of the valve ring 57. The side of the liquid separator 59 has a notch, and the side of the connecting valve disc 58 has a liquid passage groove. A semi-circular sealing groove extends to the left side from the notch of the liquid separator 59. Through the above structure, as the connecting valve pipe 56 moves further away from the inner wall of the water control end shell 54, the liquid separator 59 moves and slides with the connecting valve pipe 56, thereby increasing the space between the liquid separator 59 and the inner wall of the water control end shell 54, and playing a role in controlling the flow rate. At the same time, when the connecting valve disc 58 is rotated, the liquid passage groove on the side of the connecting valve disc 58 faces towards the notch of the liquid separator 59 or away from the notch of the liquid separator 59, thereby quickly controlling the liquid delivery and stopping.

[0027] Working principle: The water used to flush stones is connected to the connecting pipe 9 through an external pipe, allowing the liquid to enter the connecting pipe 9 and then the filter tube 2. The water is then filtered by the filter materials inside the filter tube 2. Different filter materials inside the filter tube 2 are separated by a filter membrane 13, which filters out small molecules in the water. This deep filtration process prevents bacteria from remaining in the water and causing infection. Simultaneously, the liquid transported in the filter tube 2 is transported to the connecting pipe 4 through the sealing ring 10, and then enters the circulation filter tube 12. The circulation filter tube 12 further filters the water, thus improving the filtration effect.

[0028] When motor 11 drives short shaft connecting disc 51 to rotate via output shaft, the rotation of short shaft connecting disc 51 drives pump body 52 to operate, allowing pump body 52 to draw liquid from circulating filter pipe 12 into pump body 52 through input pipe 7. This allows pump body 52 to enter water tank 53 through bottom-connected pipe. Water in water tank 53 directly enters water control end shell 54 connected to the bottom. At this time, the side of valve ring 57 pulls liquid septum 59 to move, causing liquid septum 59 to slide against the inside of water control end shell 54, driving fixed connecting valve pipe 56 to move and slide against water control groove plate 55. When connecting valve pipe 56... When the side of the water control end shell 54 is detached from its contact with the inner wall of the water control end shell 54, the upper end of the water control end shell 54 will be connected to the inner side of the liquid diaphragm plate 59 through the inner side of the connecting valve pipe 56. As the connecting valve pipe 56 moves further away from the inner wall of the water control end shell 54, the liquid diaphragm plate 59 moves and slides with the connecting valve pipe 56, thereby increasing the space between the liquid diaphragm plate 59 and the inner wall of the water control end shell 54, and playing a role in controlling the flow rate. At the same time, when the connecting valve disc 58 is rotated, the liquid passage groove opened on the side of the connecting valve disc 58 faces the notch of the liquid diaphragm plate 59 or moves away from the notch of the liquid diaphragm plate 59, thereby quickly controlling the liquid delivery and stopping.

[0029] Example 2

[0030] Please see Figure 5-7The present invention provides a technical solution: a circulating liquid pushing device 6 is provided at the inner bottom end of the short shaft connecting disc 51. The circulating liquid pushing device 6 includes an infusion pipe 61, a hot circulation pipe 62, an air-blowing end shell 63, a push rod 64, a piston 65, a regulating pipe 66, an inner through pipe 67, and an inner horizontal pipe 68. The infusion pipe 61 is fixedly connected to the side of the water-blowing end shell 54. The hot circulation pipe 62 is wound around the outside of the infusion pipe 61. The air-blowing end shell 63 is located on the outside of the hot circulation pipe 62. The push rod 64 is rotatably connected to the inner side of the short shaft connecting disc 51. The piston 65 is fixedly connected to the side of the air-blowing end shell 63. The regulating pipe 66 is fixedly connected to the top inner wall of the air-blowing end shell 63. The inner through pipe 67 is slidably connected to the inner side of the regulating pipe 66. The inner horizontal pipe 68 is fixedly connected to the inner side of the inner through pipe 67. The piston 65 is slidably connected to the end of the push rod 64. The regulating pipe 66 is connected to the hot circulation pipe 62 through a pipe. The lower half of the heat circulation tube 62 is spirally wound around the outside of the infusion tube 61, and the upper half of the heat circulation tube 62 extends into the air-filled end shell 63. A one-way valve is provided on the bottom side of the piston 65. Through the above structure, the gas in the piston 65 will enter the interior through the side hole of the inner tube 67, and will be output from the top hole to the inside of the air-filled end shell 63 through the interior of the inner tube 67, allowing air to accumulate inside the air-filled end shell 63 and increasing the air pressure. The air pressure inside the air-filled end shell 63 can be used to supply air to patients who cannot turn over for a long time during treatment. The air-filled end shell 63 supplies air to the airbag, allowing the muscles at the bottom of the patient's body to move passively as the airbag inflates when lying flat, thereby promoting blood circulation. Combined with the air circulation in the heat circulation tube 62, the heating effect of the heat circulation tube 62 on the infusion tube 61 is enhanced. By heating the liquid, the discomfort of the body to liquids below body temperature is reduced.

[0031] An anti-backflow device 8 is provided at the end of the infusion tube 61. The anti-backflow device 8 includes a one-way tube 81, a cylindrical block 82, a fixed cylindrical plate 83, a liquid passage hole 84, and an output end 85. The one-way tube 81 is fixedly connected to the end of the infusion tube 61, the fixed cylindrical plate 83 is fixedly connected to the inner side of the one-way tube 81, the cylindrical block 82 is slidably connected to the inner side of the fixed cylindrical plate 83, the liquid passage hole 84 is opened on the upper surface of the cylindrical block 82, and the output end 85 is fixedly connected to the side of the one-way tube 81. The diameter of the cross-section at both ends of the cylindrical block 82 is larger than the diameter of the cross-section at the middle. An inner through groove is opened on one side of the cylindrical block 82, and the inner through groove is connected to the liquid passage hole 84. Through the above structure, when the liquid flows back at the output end 85, the outer side of the cylindrical block 82 near the output end 85 is compressed, and with the help of the spring force, the cylindrical block 82 moves to push the liquid passage hole 84 past the fixed cylindrical plate 83, thereby sealing the connection and effectively preventing the liquid from flowing back.

[0032] Working principle: When the short shaft connecting disc 51 rotates, it drives the push rod 64 to pressurize the piston 65, causing the piston 65 to draw air from the bottom. The direction of gas delivery is controlled by the regulating pipe 66 connected to the side of the piston 65. When the inner tube 67 inside the regulating pipe 66 slides downward, aligning the hole on the outer side of the bottom end of the inner tube 67 with the side of the piston 65, the gas inside the piston 65 enters through the hole on the side of the inner tube 67 and is output from the top hole through the inner tube 67 to the inside of the air-filled end shell 63. This allows air to accumulate inside the air-filled end shell 63, increasing the air pressure. The air pressure inside the air-filled end shell 63 can be used to supply air to patients who cannot turn over for extended periods during treatment. This is achieved through the external airbag, pipes, and air-filled end shell. The connection between 63 and the inflatable end shell 63 allows the air supply to the airbag, enabling the muscles at the bottom of the patient's body to move passively as the airbag inflates when the patient is lying down, thereby promoting blood circulation. At the same time, when the inner tube 67 slides down, aligning the inner horizontal tube 68 with the side of the piston 65, the air supplied in the piston 65 will enter the tube connected to the outside of the control tube 66 through the inner horizontal tube 68, and then be supplied to the heat circulation tube 62 through this tube. This allows the gas to drive the air circulation in the heat circulation tube 62, and the heat circulation tube 62 will be in a heating state after being energized. In conjunction with the air circulation in the heat circulation tube 62, the heating effect of the heat circulation tube 62 on the infusion tube 61 is improved. By heating the liquid, the discomfort of the body to liquids below body temperature is reduced.

[0033] When liquid is transferred from the infusion tube 61 to the one-way tube 81, the liquid in the one-way tube 81 enters through the cylinder 82 and is pushed outward by the liquid pressure, squeezing the spring. This allows the liquid passage hole 84 on the side of the cylinder 82 to pass through the solid cylinder 83, and the liquid in the cylinder 82 flows out through the liquid passage hole 84 and is output through the output end 85. When the liquid flows back through the output end 85, the side of the cylinder 82 near the output end 85 is compressed, and with the spring force, the cylinder 82 moves to push the liquid passage hole 84 past the solid cylinder 83, which has a sealing and connecting effect, thus effectively preventing the liquid from flowing back.
