Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to an intelligent temperature-controlled irrigation device for the treatment of otitis media. Background Technology

[0002] Otitis media is a common disease in otolaryngology, especially in children. Ear irrigation is a basic and important adjunctive method in its treatment. By injecting a suitable irrigation solution into the affected ear, secretions, pus, crusts, and pathogens in the ear canal can be effectively removed, keeping the ear canal clean, creating a good environment for local medication, and promoting the resolution of inflammation and the repair of the mucosa.

[0003] Currently, clinical ear canal irrigation mainly relies on simple devices, such as syringes connected to blunt-tipped needles or specialized irrigation heads, to manually inject saline or other irrigation solutions. While this method is simple and inexpensive, it has many limitations and drawbacks in practical application. First, the irrigation process depends entirely on the operator's experience and feel; the flow rate and pressure of the irrigation solution are difficult to control precisely. Excessive flow or pressure may cause patient discomfort or even impact the tympanic membrane, posing potential risks; insufficient flow may result in incomplete irrigation, affecting the therapeutic effect. Second, the temperature control of the irrigation solution is not precise enough. Irrigation solutions close to body temperature significantly improve patient comfort, reduce discomfort such as dizziness caused by cold stimulation, and promote local blood circulation. However, existing methods usually rely on medical staff to preheat the irrigation solution, which not only makes it difficult to maintain a constant temperature but also causes it to gradually decrease due to heat dissipation during irrigation, leading to temperature fluctuations that affect treatment effectiveness and patient experience. Summary of the Invention

[0004] This invention aims to provide an intelligent temperature-controlled irrigation device for the treatment of otitis media. It utilizes a liquid-drawing component to draw irrigation fluid for rinsing the ear canal, with controllable flow rate and pressure. A heating component heats the drawn irrigation fluid, ensuring a constant and uniform temperature during rinsing. This solves the problems in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A smart temperature-controlled irrigation device for treating otitis media includes an irrigation base connected to a reservoir for holding irrigation fluid. The irrigation base is also connected to a fluid-collecting assembly, a heating assembly, and a control module. The fluid-collecting assembly includes a fluid-collecting tank connected to the irrigation base and a motor. The fluid-collecting tank has a fluid-collecting chamber on its inner side, and a pair of meshing fluid-collecting gears are rotatably mounted on the inner side of the fluid-collecting chamber. Either of the fluid-collecting gears is fixedly connected to the output shaft of the motor. The inlet end of the fluid-collecting chamber is connected to the reservoir via a fluid-collecting pipe. The liquid outlet of the liquid-collecting chamber is connected to a liquid guide tube located inside the rinsing substrate. The liquid guide tube is connected to a rinsing head located outside the rinsing substrate via a liquid guide pipe. The heating assembly includes a sliding rod, a heating resistor, and a battery. The heating resistor is sleeved on the outside of the liquid guide tube to heat it. The sliding rod slides against the heating resistor, and the sliding rod and the heating resistor are electrically connected to the positive and negative terminals of the battery, respectively. The heating power of the heating assembly is related to the connection position of the sliding rod relative to the heating resistor. The control module is electrically connected to the motor and controls its operation.

[0007] Furthermore, the heating assembly also includes a linkage cylinder, which has an impact section. The linkage cylinder is slidably sleeved on the outside of the liquid guide cylinder and the liquid guide tube, and the flushing liquid flowing out from the liquid guide cylinder impacts the impact section of the linkage cylinder. The linkage cylinder is connected to the slide rod, and the linkage cylinder is also connected to a spring. The end of the spring away from the linkage cylinder is fixedly connected to the flushing base.

[0008] Furthermore, the liquid guiding cylinder is provided with a sliding part, and the linkage cylinder is slidably sleeved on the outside of the sliding part; the impact part of the linkage cylinder is wedge-shaped, and the maximum inner diameter of the impact part is not less than the inner diameter of the sliding part.

[0009] Furthermore, there are four heating components, and the four heating components are electrically connected to the battery in parallel; the heating resistors of the four heating components are evenly arranged around the liquid guide tube, and the spring is located inside the space enclosed by the sliding rods of the four heating components.

[0010] Furthermore, it also includes a drainage assembly, which includes a drainage tube. The flushing head and the drainage tube are connected to the end of the liquid guide tube away from the liquid guide cylinder via a three-way pipe. The end of the drainage tube away from the three-way pipe is connected to an external collection bag. Both the drainage tube and the liquid guide tube are connected to a liquid one-way valve. The liquid one-way valve connected to the liquid guide tube controls the flushing fluid to flow unidirectionally from the liquid guide cylinder to the flushing head side. The liquid one-way valve connected to the drainage tube controls the accumulated liquid to flow unidirectionally from the flushing head to the external collection bag side. The motor is a servo motor. When the motor rotates forward, the liquid suction assembly draws the flushing fluid from the liquid storage tank and flows out of the flushing head. When the motor rotates in reverse, the liquid suction assembly draws the accumulated liquid and flows out of the drainage tube.

[0011] Furthermore, a damping bushing is connected to the outside of the flushing substrate, the liquid guide tube slides through the damping bushing, and the flushing head is located on the outside of the damping bushing.

[0012] Furthermore, the liquid storage tank, the liquid drawing tank, the motor, the battery, and the control module are all detachably connected to the rinsing base; wherein, the liquid drawing tank is provided with a sliding groove, and the liquid storage tank is provided with a slider that cooperates with the sliding groove.

[0013] Furthermore, the cross-sections of both the groove and the slider are convex, and the slider is slidably disposed on the inner side of the groove.

[0014] Furthermore, an ear cover is detachably connected to the outside of the flushing head, and the end of the flushing head away from the liquid guide tube is wedge-shaped.

[0015] Furthermore, a support base is provided on the lower side of the rinsing base, and a handle is connected to the upper side of the rinsing base.

[0016] The principles and beneficial effects of the technical solution are as follows:

[0017] 1. This invention provides an intelligent temperature-controlled irrigation device for the treatment of otitis media. The irrigation base is connected to a liquid storage tank, a liquid suction assembly, a heating assembly, and a control module. The liquid suction chamber of the liquid suction assembly is connected to the liquid storage tank via a liquid suction pipe. A pair of meshing liquid suction gears are connected to the inner side of the liquid suction chamber, and either liquid suction gear is connected to the output shaft of a motor. When the motor is running, the pair of liquid suction gears rotate, drawing the irrigation fluid contained in the inner side of the liquid storage tank into the liquid suction chamber and pressurizing it before it flows out from the guide tube (the liquid suction assembly is equivalent to a gear pump, which can not only draw the irrigation fluid but also pressurize it). The irrigation fluid entering the inner side of the guide tube is then directed through the guide pipe and the irrigation head to... The patient's ear canal is rinsed. By controlling the motor's output power and speed, the flow rate and pressure of the rinsing can be controlled. The heating resistor of the heating component is sleeved on the outside of the fluid guide tube to heat the rinsing fluid inside and outside the tube. The sliding rod of the heating component slides against the heating resistor, and the heating power of the heating component is related to the connection position of the sliding rod relative to the heating resistor. By adjusting the position of the sliding rod relative to the heating resistor, the heating power can be adjusted, which in turn adjusts the temperature of the rinsing fluid. The heating resistor is in close contact with the fluid guide tube, ensuring precise temperature control of the fluid guide tube and the rinsing fluid inside, resulting in a constant and uniform temperature of the rinsing fluid, good therapeutic effect, and excellent patient experience.

[0018] 2. This invention provides an intelligent temperature-controlled irrigation device for the treatment of otitis media. The linkage cylinder of the heating component is connected to the slide rod, and a spring connects the linkage cylinder to the irrigation base. The linkage cylinder has an impact part and is slidably sleeved on the outside of the liquid guide cylinder and the liquid guide tube. The irrigation fluid flowing from the liquid guide cylinder impacts the impact part of the linkage cylinder, causing the liquid guide cylinder to slide relative to the irrigation base against the spring force, thereby driving the slide rod to slide relative to the heating resistor (the connection position between the two changes, and the heating power of the heating component changes). The more irrigation fluid the liquid-collecting component absorbs / the greater the pressure applied to the irrigation fluid by the liquid-collecting component, the more irrigation fluid... The greater the force exerted by the impact linkage cylinder (momentum is directly proportional to mass and velocity), the greater the force exerted by the liquid guide cylinder on the spring. This results in a greater spring deformation / relative displacement of the slide relative to the heating resistor, and thus a higher heating power of the heating assembly, ensuring effective heating of the flushing fluid. Conversely, when the amount of flushing fluid drawn by the liquid suction assembly decreases / the pressure applied to the flushing fluid by the liquid suction assembly decreases, the force exerted by the flushing fluid on the linkage cylinder decreases, the force exerted by the liquid guide cylinder on the spring decreases, resulting in a smaller spring deformation / relative displacement of the slide relative to the heating resistor, and a smaller heating power of the heating assembly, thus preventing overheating of the flushing fluid. In other words, the heating power of the heating assembly is positively correlated with the amount of flushing fluid drawn by the liquid suction assembly and the pressure applied to the flushing fluid, further improving the constancy and uniformity of the flushing fluid temperature. The liquid guide tube is equipped with a sliding part, and the linkage tube is slidably sleeved on the outside of the sliding part to ensure the connection between the linkage tube and the liquid guide tube and prevent the flushing fluid from overflowing from the end face of the linkage tube or the liquid guide tube. The impact part of the linkage tube is wedge-shaped, and the maximum inner diameter of the impact part is not less than the inner diameter of the sliding part, to ensure that the flushing fluid flowing out of the liquid guide tube can impact the impact part, thereby ensuring the linkage effect between the heating component and the liquid suction component. There are four heating components, and the electrical connection between the four heating components and the battery is in parallel. The heating resistors of the four heating components are evenly distributed around the liquid guide tube, further improving the uniformity of heating the liquid guide tube / flushing fluid. The spring is located inside the space enclosed by the sliding rods of the four heating components, so that the four sliding rods and the spring are subjected to uniform force, further improving the functionality and stability of the entire device.

[0019] 3. This invention provides an intelligent temperature-controlled irrigation device for the treatment of otitis media, which also includes a drainage component. Both the drainage tube and the liquid guide tube of the drainage component are connected to a one-way valve to control the direction of liquid flow. The motor is a servo motor, allowing adjustment of the rotation direction of its output shaft. When the motor's output shaft rotates forward, the liquid-collecting component draws irrigation fluid from the reservoir and flows out through the irrigation head to irrigate the ear canal. When the motor's output shaft rotates in reverse, the liquid-collecting component draws accumulated fluid from the ear canal and flows out through the drainage tube. Thus, the entire irrigation device not only performs irrigation but also suctions / drains accumulated fluid from the ear canal after irrigation, further expanding the device's functionality and benefiting clinical use. A damping sleeve is connected to the outside of the irrigation base, and the liquid guide tube slides through the damping sleeve, allowing the irrigation / suction angle to be adjusted according to actual needs.

[0020] 4. The present invention provides an intelligent temperature-controlled flushing device for the treatment of otitis media. The liquid storage tank, the liquid collection tank, the motor, the battery, and the control module are all detachably connected to the flushing base to facilitate cleaning and disinfection of the liquid storage tank, the liquid collection tank, etc. The liquid collection tank is provided with a sliding groove, and the liquid storage tank is provided with a slider that cooperates with the sliding groove to facilitate the disassembly of the liquid storage tank from the liquid collection tank, thereby enabling the adjustment of the composition and concentration of the flushing liquid in the liquid collection tank. The cross-section of both the sliding groove and the slider is convex. The slider is slidably disposed inside the sliding groove. When the liquid storage tank is disassembled and assembled, the slider and the sliding groove guide and limit the relative movement of the two (the liquid storage tank and the liquid collection tank) to ensure the uniformity and stability of the relative movement, and further ensure the functionality of the entire device.

[0021] 5. The present invention provides an intelligent temperature-controlled irrigation device for the treatment of otitis media. The outer side of the irrigation head is detachably connected to an ear sleeve, and the end of the irrigation head away from the liquid guide tube is wedge-shaped to improve the connection effect between the irrigation head and the ear canal, thereby ensuring the irrigation / suction functionality. A support base is provided on the lower side of the irrigation base, and a handle is connected to the upper side of the irrigation base to improve the convenience of using the entire irrigation device.

The irrigation base 1 is detachably connected to a liquid storage tank 2, a liquid suction assembly, a heating assembly, and a control module 20. The liquid storage tank 2 is used to hold irrigation fluid. The liquid suction assembly includes a liquid suction tank 4 connected to the irrigation base 1 and a motor 5. A liquid suction chamber 6 is provided inside the liquid suction tank 4, and a rotatable heating element is provided inside the liquid suction chamber 6. A pair of meshing liquid-drawing gears 7, the lower liquid-drawing gear 7 is fixedly connected to the output shaft of the motor 5; the liquid inlet of the liquid-drawing chamber 6 is connected to the liquid storage tank 2 through the liquid-drawing pipe 3, and the liquid outlet of the liquid-drawing chamber 6 is connected to the liquid guide tube 8 located inside the rinsing base 1. The liquid guide tube 8 is connected to the rinsing head 15 located outside the rinsing base 1 through the liquid guide tube 14. The outer side of the rinsing head 15 is detachably connected to an ear sleeve (not shown in the figure), and the end of the rinsing head 15 away from the liquid guide tube 14 is wedge-shaped. A damping sleeve 17 is also connected to the outside of the flushing base 1. The liquid guide tube 14 slides through the damping sleeve 17, and the flushing head 15 is located on the outside of the damping sleeve 17. The heating assembly includes a slide rod 10, a heating resistor 11, a linkage cylinder 9, and a battery 13. The linkage cylinder 9 is provided with an impact part. The linkage cylinder 9 is slidably sleeved on the outside of the liquid guide cylinder 8 and the liquid guide tube 14, and the flushing liquid flowing out from the liquid guide cylinder 8 impacts the impact part of the linkage cylinder 9. The heating resistor 11 is sleeved on the outside of the liquid guide tube 14 to perform flushing. Heating is performed; the linkage cylinder 9 is also connected to a spring 12, the end of the spring 12 away from the linkage cylinder 9 is fixedly connected to the rinsing base 1, one end of the slide rod 10 is connected to the linkage cylinder 9, the end of the slide rod 10 away from the linkage cylinder 9 slides against the heating resistor 11, and the slide rod 10 and the heating resistor 11 are electrically connected to the positive and negative terminals of the storage battery 13 respectively. The heating power of the heating component is related to the connection position of the slide rod 10 relative to the heating resistor 11; the control module 20 is electrically connected to the motor 5 and controls its operation.

[0031] In this embodiment, the liquid guiding cylinder 8 is provided with a sliding part, and the linkage cylinder 9 is slidably sleeved on the outside of the sliding part; the impact part of the linkage cylinder 9 is wedge-shaped, and the maximum inner diameter of the impact part is larger than the inner diameter of the sliding part. There are four heating components, and the electrical connection between the four heating components and the storage battery 13 is in parallel. The heating resistors 11 of the four heating components are evenly arranged around the liquid guiding pipe 14, and the spring 12 is located inside the space enclosed by the sliding rods 10 of the four heating components. The liquid drawing tank 4 is provided with a sliding groove, and the liquid storage tank 2 is provided with a slider that cooperates with the sliding groove; wherein, the cross-section of both the sliding groove and the slider is convex, and the slider is slidably disposed inside the sliding groove.

[0032] In addition, this embodiment also includes a drainage component, which includes a drainage pipe 16. The flushing head 15 and the drainage pipe 16 are connected to the end of the liquid guide pipe 14 away from the liquid guide cylinder 8 through a three-way pipe. The end of the drainage pipe 16 away from the three-way pipe is connected to the external collection bag. Both the drainage pipe 16 and the liquid guide pipe 14 are connected to a liquid one-way valve 19. The liquid one-way valve 19 connected to the liquid guide pipe 14 controls the flushing liquid to flow unidirectionally from the liquid guide cylinder 8 to the flushing head 15. The liquid one-way valve 19 connected to the drainage pipe 16 controls the accumulated liquid to flow unidirectionally from the flushing head 15 to the external collection bag. The motor 5 is a servo motor 5. When the motor 5 rotates forward, the liquid suction component draws the flushing liquid in the liquid storage tank 2 and flows out from the flushing head 15. When the motor 5 rotates in reverse, the liquid suction component draws the accumulated liquid and flows out from the drainage pipe 16.

[0033] The specific implementation process is as follows:

[0034] When using this irrigation device, according to actual clinical needs, the corresponding composition / concentration of irrigation solution is filled into the reservoir 2, and the damping sleeve 17 is rotated as needed for irrigation or suction to ensure that the angle between the irrigation head 15 and the ear canal is at the optimal irrigation / suction angle. Then, the operation of the motor 5 is controlled by the control module 20. When the ear canal needs to be irrigated, the output shaft of the motor 5 is controlled to rotate forward, and the liquid suction component draws the irrigation solution from the reservoir 2, heats it through the heating component, and then flows out from the irrigation head 15 to irrigate the patient's ear canal. When it is necessary to suction the liquid in the ear canal, the output shaft of the motor 5 is controlled to rotate in reverse, and the liquid suction component draws the accumulated liquid in the ear canal, which flows out from the drainage tube 16 and is collected in the collection bag.

[0035] When the motor 5 is running, a pair of liquid-drawing gears 7 rotate, drawing the flushing fluid contained inside the liquid storage tank 2 into the liquid-drawing chamber 6 and pressurizing it before it flows out from the liquid guide tube 8. The flushing fluid entering the liquid guide tube 8 flows through the liquid guide tube 14 and the flushing head 15 to flush the patient's ear canal. By controlling the output power and speed of the motor 5, the flow rate and pressure of the flushing can be controlled. The flushing fluid flowing out from the liquid guide tube 8 impacts the impact part of the linkage tube 9, causing the liquid guide tube 8 to slide relative to the flushing base 1 against the force of the spring 12, thereby changing the heating power of the heating component. Specifically: the more flushing fluid the suction assembly draws in / the greater the pressure applied to the flushing fluid by the suction assembly, the greater the force of the flushing fluid impacting the linkage cylinder 9, the greater the force exerted by the guide cylinder 8 on the spring 12, the greater the deformation of the spring 12 / the greater the relative displacement of the slide rod 10 relative to the heating resistor 11, and the greater the heating power of the heating assembly, ensuring effective heating of the flushing fluid. Conversely, when the amount of flushing fluid drawn in by the suction assembly decreases / the pressure applied to the flushing fluid by the suction assembly decreases, the force of the flushing fluid impacting the linkage cylinder 9 decreases, the force exerted by the guide cylinder 8 on the spring 12 decreases, resulting in a decrease in the deformation of the spring 12 / the greater the relative displacement of the slide rod 10 relative to the heating resistor 11, and a decrease in the heating power of the heating assembly, thus reducing the overheating of the flushing fluid. In other words, the heating power of the heating assembly is positively correlated with the amount of flushing fluid drawn in by the suction assembly and the pressure applied to the flushing fluid, resulting in good temperature stability and uniformity of the flushing fluid. The liquid guide tube 8 is equipped with a sliding part, and the linkage tube 9 is slidably sleeved on the outside of the sliding part, which can effectively prevent the flushing liquid from overflowing from the end face of the linkage tube 9 or the liquid guide tube 8. The impact part of the linkage tube 9 is wedge-shaped, and the maximum inner diameter of the impact part is not less than the inner diameter of the sliding part, so as to ensure that the flushing liquid flowing out of the liquid guide tube 8 can impact the impact part, and the linkage effect between the heating component and the liquid suction component is good. There are four heating components, and the electrical connection between the four heating components and the battery 13 is in parallel. The heating resistors 11 of the four heating components are evenly arranged around the liquid guide tube 14, and the heating components provide good uniformity of heating the liquid guide tube 14 / flushing liquid.

[0036] Both the drainage tube 16 and the fluid guide tube 14 of the drainage assembly are connected to a one-way valve 19 to control the direction of fluid flow. The motor 5 is a servo motor, allowing its output shaft to rotate in an adjustable direction. When the output shaft of the motor 5 rotates forward, the fluid suction assembly draws the rinsing fluid from the reservoir 2 and flows out through the rinsing head 15 to rinse the ear canal. When the output shaft of the motor 5 rotates in reverse, the fluid suction assembly draws the accumulated fluid in the ear canal and flows out through the drainage tube 16. Thus, the entire rinsing device not only performs rinsing but also suctions / drains the accumulated fluid in the ear canal after rinsing. The entire device has complete clinical functions and is beneficial for clinical application. A damping sleeve 17 is connected to the outside of the rinsing base 1, and the fluid guide tube 14 slides through the damping sleeve 17, allowing the rinsing / suction angle to be adjusted according to actual needs.

[0037] The liquid-collecting tank 4 is provided with a sliding groove, and the liquid-storage tank 2 is provided with a slider that cooperates with the sliding groove, so that the liquid-storage tank 2 can be disassembled from the liquid-collecting tank 4 to adjust the composition and concentration of the flushing liquid in the liquid-collecting tank 4. The sliding groove and the slider are both convex in cross-section. The slider is slidably located inside the sliding groove. When disassembling and assembling the liquid-storage tank 2, the slider and the sliding groove guide and limit the relative movement of the two (liquid-storage tank 2 and liquid-collecting tank 4) to ensure the uniformity and stability of the relative movement, and further ensure the functionality of the entire device.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solutions of the present invention, and these should also be considered within the scope of protection of the present invention.
