Description

Technical Field

[0001] This invention belongs to the field of medical device technology, and in particular relates to a postoperative nasal irrigation device for otolaryngology. Background Technology

[0002] Currently, after nasal surgery, otolaryngologists typically use nasal irrigation solutions to clean the patient's nasal cavity. The core purpose of this procedure is to deliver the irrigation solution into the nasal cavity using a specific method to remove secretions, blood clots, scabs, residual medications, and contaminants, thereby aiding in postoperative nasal mucosal repair, reducing the risk of infection, and improving treatment outcomes.

[0003] However, in actual clinical irrigation procedures, medical staff often use a syringe to aspirate the irrigation fluid. Due to the limited capacity of the syringe, repeated aspiration is necessary throughout the irrigation process, making the operation cumbersome. Furthermore, the irrigation force must be manually controlled by the medical staff, and manual operation makes it difficult to maintain consistent irrigation force, directly leading to poor overall irrigation results. In addition, traditional syringes lack effective filtration of the irrigation fluid, allowing undissolved particles to enter the nasal cavity directly, further causing discomfort to the patient.

[0004] Therefore, we propose a postoperative nasal irrigation device for otolaryngology to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to address the above-mentioned problems by providing a postoperative nasal irrigation device for otolaryngology.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a postoperative nasal irrigation device for otolaryngology, comprising a support base, on which a waste liquid collection tank and a storage tank are fixedly mounted; the waste liquid collection tank is fixedly connected to a liquid guide seat via a liquid guide pipe; a stirrer is installed on the storage tank, and a temperature control mechanism is provided on the storage tank; a miniature infusion pump is fixedly connected to the support base, and the input end of the miniature infusion pump is fixedly connected to the storage tank via a suction tube; a filter box is fixedly connected to the support base, and the filter box is fixedly connected to the output end of the miniature infusion pump via a delivery pipe; a filter screen is fixedly connected to the filter box, and a filter detection mechanism for detecting the status of the filter screen is provided in the filter box; a stirring and vibration mechanism cooperating with the filter detection mechanism is provided on the filter box; a drain port is fixedly connected to the upper side of the filter box, and a disposable irrigation hose is fixedly connected to the drain port; a power regulation mechanism cooperating with the miniature infusion pump is provided on the support base; and a PLC controller is provided on the support base, and the PLC controller is used to control various electrical devices.

[0007] In the above-mentioned postoperative nasal irrigation device for otolaryngology, the temperature control mechanism includes a temperature sensor and multiple electric heating blocks. The temperature sensor is fixedly mounted on the liquid storage tank, and the detection end of the temperature sensor extends into the liquid storage tank. Each of the electric heating blocks is fixedly embedded in the inner bottom surface of the liquid storage tank, and each electric heating block and the temperature sensor are electrically connected to the PLC controller.

[0008] In the aforementioned postoperative nasal irrigation device for otolaryngology, the filtration and detection mechanism includes multiple ultraviolet germicidal lamps and multiple photosensitive sensors. Each ultraviolet germicidal lamp is fixedly installed on the inner top surface of the filter box, and a transparent cover for protecting the ultraviolet germicidal lamps is fixedly connected in the filter box. The ultraviolet germicidal lamps are arranged in a ring. An installation groove is opened on the inner bottom surface of the filter box, and a transparent block is fixedly embedded in the top of the installation groove. Each photosensitive sensor is fixedly installed in its corresponding installation groove, and each photosensitive sensor corresponds one-to-one with each ultraviolet germicidal lamp. Each ultraviolet germicidal lamp and photosensitive sensor is electrically connected to a PLC controller.

[0009] In the above-mentioned postoperative nasal irrigation device for otolaryngology, the stirring and vibration mechanism includes a miniature stirring motor, a stirring blade, and multiple vibration components. The stirring blade is rotatably disposed in a filter box, and the drive shaft of the stirring blade is connected to the miniature stirring motor. The miniature stirring motor can be automatically controlled to start and stop by a PLC controller based on the detection feedback of a photosensitive sensor. Each vibration component is fixedly disposed on the stirring blade, and the vibration end of the vibration component is in contact with the filter screen.

[0010] In the above-mentioned postoperative nasal irrigation device for otolaryngology, the vibration component includes a slide cylinder, a T-shaped slider, and a vibrating ball. The slide cylinder is fixedly mounted on the stirring blade, and the T-shaped slider is slidably connected to the slide cylinder. The T-shaped slider is fixedly connected to the slide cylinder by a telescopic spring, and the vibrating ball is fixedly mounted on the upper end of the T-shaped slider. A plurality of protrusions that cooperate with the vibrating ball are fixedly mounted on the lower side of the filter screen.

[0011] In the aforementioned postoperative nasal irrigation device for otolaryngology, the power control mechanism includes a control box, a miniature forward and reverse motor, a lead screw, a sliding rheostat, and a laser displacement sensor. The control box is fixedly mounted on a support base. The sliding rheostat is fixedly mounted in the control box and electrically connected to a miniature infusion pump. The lead screw is rotatably mounted in the control box, and one end of the lead screw is drivenly connected to the miniature forward and reverse motor. An insulating block is threaded onto the lead screw. One end of the insulating block is fixedly connected to the sliding end of the sliding rheostat, and the other end of the insulating block is fixedly connected to a detection block. The laser displacement sensor is fixedly mounted on the inner top surface of the control box, and the laser displacement sensor is positioned opposite to the detection block. Both the laser displacement sensor and the miniature forward and reverse motor are electrically connected to a PLC controller.

[0012] In the above-mentioned postoperative nasal irrigation device for otolaryngology, two cylinders are fixedly installed on the waste liquid collection tank, and the output ends of the two cylinders are fixedly connected to the liquid guide seat. The liquid guide tube is a corrugated telescopic tube, and a one-way valve is installed on the liquid guide tube.

[0013] In the above-mentioned postoperative nasal irrigation device for otolaryngology, the drain port and the disposable irrigation hose are connected by a threaded connection, and a support ring for supporting the disposable irrigation hose is fixedly provided on the filter box.

[0014] Compared with existing technologies, the advantages of a postoperative nasal irrigation device for otolaryngology are: 1. The system stores the flushing solution in a reservoir and automatically draws and delivers it using a miniature infusion pump. This eliminates the need for medical staff to repeatedly operate syringes, avoiding the tediousness of manual operation. The power control mechanism allows for adjustment of the pump's output power by changing the resistance of a sliding rheostat, enabling the flushing intensity to gradually increase from weak to strong, allowing patients to adapt. Simultaneously, a laser displacement sensor helps preset the final flushing intensity, ensuring stability and resolving the issue of uneven intensity during manual operation.

[0015] 2. The filter screen can filter the rinsing solution used, preventing undissolved particles from entering the patient's nasal cavity and causing discomfort. The filter detection mechanism can use the ultraviolet germicidal lamp in the filter detection mechanism to sterilize the rinsing solution in the filter box to a certain extent, reducing the risk of infection. At the same time, the photosensitive sensor in the filter detection mechanism can work with the ultraviolet germicidal lamp to detect the light intensity based on the degree of filter blockage and promptly feed the signal back to the PLC controller for easy monitoring of the filter status.

[0016] 3. Through the set stirring and vibration mechanism, the micro stirring motor can be started by the PLC controller when the filter screen is clogged to a certain extent, driving the stirring blade to rotate, stirring the rinsing liquid in the filter box, promoting the shedding of undissolved particles attached to the filter screen and accelerating their dissolution; the vibration component, through the cooperation of the vibrating ball and the protrusion on the lower side of the filter screen, knocks and vibrates the filter screen when the stirring blade rotates, further cleaning the particles, ensuring the filtration performance of the filter screen, and avoiding clogging that affects rinsing.

Detailed Implementation

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] like Figures 1-5As shown, a postoperative nasal irrigation device for otolaryngology includes a support base 1, on which a waste liquid collection tank 2 and a storage tank 3 are fixedly mounted. The waste liquid collection tank 2 is fixedly connected to a guide seat 5 via a guide pipe 4. Two cylinders 29 are fixedly mounted on the waste liquid collection tank 2, and the output ends of the two cylinders 29 are fixedly connected to the guide seat 5. The guide pipe 4 is a corrugated telescopic pipe, and a one-way valve 30 is provided on the guide pipe 4. The cooperation of the cylinders 29 and the corrugated telescopic pipe allows the user to adjust the height of the guide seat 5 as needed. The one-way valve 30 can prevent the waste liquid in the waste liquid collection tank 2 from flowing back.

[0021] A stirrer 6 is installed on the reservoir 3, and a temperature control mechanism 7 is provided on the reservoir 3. The temperature control mechanism 7 includes a temperature sensor 71 and multiple electric heating blocks 72. The temperature sensor 71 is fixedly installed on the reservoir 3, and the detection end of the temperature sensor 71 extends into the reservoir 3. Each electric heating block 72 is fixedly embedded in the inner bottom surface of the reservoir 3, and each electric heating block 72 and the temperature sensor 71 are electrically connected to the PLC controller 18. The temperature sensor 71 can monitor the temperature of the flushing fluid in real time. When the temperature of the flushing fluid is low, especially in the low temperature environment of winter, when the temperature sensor 71 feeds back the detected low temperature signal to the PLC controller 18, the PLC controller 18 will start the electric heating blocks 72 to heat the flushing fluid until the flushing fluid is heated to a suitable temperature so that the patient can have a better flushing experience.

[0022] A micro infusion pump 8 is fixedly connected to the support base 1, and the input end of the micro infusion pump 8 is fixedly connected to the storage tank 3 through the suction tube 9. A filter box 10 is fixedly connected to the support base 1, and the filter box 10 is fixedly connected to the output end of the micro infusion pump 8 through the delivery pipe 11. A filter screen 12 is fixedly connected in the filter box 10, and a filter detection mechanism 13 for detecting the state of the filter screen 12 is provided in the filter box 10.

[0023] The filtration detection mechanism 13 includes multiple ultraviolet germicidal lamps 131 and multiple photosensitive sensors 132. Each ultraviolet germicidal lamp 131 is fixedly installed on the inner top surface of the filter box 10, and a transparent cover 19 for covering and protecting the ultraviolet germicidal lamps 131 is fixedly connected in the filter box 10. The ultraviolet germicidal lamps 131 are arranged in a ring. An installation groove 20 is opened on the inner bottom surface of the filter box 10, and a transparent block 21 is fixedly embedded in the top of the installation groove 20. Each photosensitive sensor 132 is fixedly installed in its corresponding installation groove 20, and each photosensitive sensor 132 corresponds one-to-one with each ultraviolet germicidal lamp 131. Each ultraviolet germicidal lamp 131 and photosensitive sensor 132 is electrically connected to the PLC controller 18. The ultraviolet germicidal lamp 131 can sterilize the rinsing solution. At the same time, the photosensitive sensor 132 can detect the light intensity of the ultraviolet germicidal lamp 131. This detection process is related to the clogging status of the filter screen 12. When the filter screen 12 is clogged to a certain extent, the photosensitive sensor 132 will feed back the corresponding electrical signal to the PLC controller 18, so that the PLC controller 18 can monitor the clogging status of the filter screen 12 in a timely manner.

[0024] The filter box 10 is equipped with a stirring and vibration mechanism 14 that cooperates with the filter detection mechanism 13. The stirring and vibration mechanism 14 includes a micro stirring motor 141, a stirring blade 142, and multiple vibration components 143. The stirring blade 142 is rotatably mounted in the filter box 10, and the drive shaft of the stirring blade 142 is connected to the micro stirring motor 141. The micro stirring motor 141 can be automatically controlled to start and stop by the PLC controller 18 based on the detection feedback of the photosensitive sensor 132. Each vibration component 143 is fixedly mounted on the stirring blade 142, and the vibration end of the vibration component 143 is connected to the stirring blade 142. The filter screen 12 is connected to the contact point. The micro stirring motor 141 can control the rotation of the stirring blade 142. The rotation of the stirring blade 142 will cause the liquid to flow and turbulent. This fluid movement will generate a certain impact force and shear force on the surface of the filter screen 12, which will promote the shedding of undissolved particles attached to the filter screen 12. During the rotation of the stirring blade 142, the dissolution of undissolved particles will be accelerated. At the same time, in conjunction with the rotation of the stirring blade 142, each vibration component 143 will rotate synchronously, expanding the vibration range and improving the effect of the filter screen 12 in shaking off the attached undissolved particles.

[0025] The vibration assembly 143 includes a slide cylinder 22, a T-shaped slider 23, and a vibrating ball 24. The slide cylinder 22 is fixedly mounted on the stirring blade 142, and the T-shaped slider 23 is slidably connected to the slide cylinder 22. The T-shaped slider 23 is fixedly connected to the slide cylinder 22 via a telescopic spring 25, and the vibrating ball 24 is fixedly mounted on the upper end of the T-shaped slider 23. The lower side of the filter screen 12 is fixedly provided with multiple protrusions 26 that cooperate with the vibrating ball 24. Through the cooperation of the vibrating ball 24 and the telescopic spring 25, the vibrating ball 24 can intermittently touch and squeeze each protrusion 26 during the rotation of the stirring blade 142, thereby realizing the automatic extension and retraction of the vibrating ball 24. This allows the vibrating ball 24 to automatically tap the filter screen 12, causing the filter screen 12 to vibrate. The vibration force accelerates the shedding of undissolved particles attached to the filter screen 12.

[0026] The upper side of the filter box 10 is fixedly connected to a drain port 15, and the drain port 15 is fixedly connected to a disposable rinsing hose 16. The drain port 15 and the disposable rinsing hose 16 are connected by a threaded connection. A support ring 31 for supporting the disposable rinsing hose 16 is fixedly provided on the filter box 10. The threaded connection makes it easy for the user to disassemble and replace the disposable rinsing hose 16. The support ring 31 provides support for the disposable rinsing hose 16.

[0027] A power regulation mechanism 17, which works in conjunction with a miniature infusion pump 8, is mounted on the support base 1. A PLC controller 18 is also mounted on the support base 1 and is used to control various electrical devices. The power regulation mechanism 17 includes a control box 171, a miniature forward and reverse motor 172, a lead screw 173, a sliding rheostat 174, and a laser displacement sensor 175. The control box 171 is fixedly mounted on the support base 1. The sliding rheostat 174 is fixedly mounted in the control box 171 and is electrically connected to the miniature infusion pump 8. The lead screw 173 is rotatably mounted in the control box 171, and one end of the lead screw 173 is connected to the miniature forward and reverse motor 172. An insulating block 27 is threaded onto the lead screw 173, and one end of the insulating block 27 is connected to the sliding rheostat 172. The sliding end of 4 is fixedly connected, and the other end of the insulating block 27 is fixedly connected to the detection block 28. The laser displacement sensor 175 is fixedly installed on the inner top surface of the control box 171, and the laser displacement sensor 175 is arranged opposite to the detection block 28. The laser displacement sensor 175 and the micro forward and reverse motor 172 are both electrically connected to the PLC controller 18. Through the cooperation of the micro forward and reverse motor 172 and the lead screw 173, the resistance value of the sliding rheostat 174 can be adjusted, thereby controlling the output power of the micro infusion pump 8. Furthermore, through the laser displacement sensor 175, the final resistance value of the sliding rheostat 174 can be set, which allows medical staff to preset the final output power of the micro infusion pump 8 as needed, thereby controlling the final flushing force of the flushing fluid.

[0028] The operating principle of the present invention is described as follows: When using this rinsing device, it can be powered by an external power supply or a battery. First, inject the required rinsing solution into the nasal cavity through the injection port of the storage tank 3 according to the ratio. After injection, close the injection port of the storage tank 3 and start the stirrer 6 to automatically stir the injected solution to ensure that the solutions are fully mixed. After stirring, the patient inserts the rinsing head of the disposable rinsing hose 16 into the nasal cavity to be rinsed. Then, the micro infusion pump 8 is started by the PLC controller 18. After the micro infusion pump 8 is started, it will draw the rinsing solution from the storage tank 3 and guide it to the filter box 10 through the suction tube 9 and the delivery tube 11. The rinsing solution is filtered by the filter screen 12 and enters the patient's nasal cavity through the disposable rinsing hose 16 for rinsing. The waste liquid generated during the rinsing process will be collected in the waste liquid collection box 2 through the liquid guide seat 5 to avoid polluting the surrounding environment. After the flushing fluid is sprayed from the disposable flushing hose 16, the PLC controller 18 controls the start of the miniature forward and reverse motor 172 and the laser displacement sensor 175. The miniature forward and reverse motor 172 controls the lead screw 173 to rotate. As the lead screw 173 rotates, the insulating block 27 drives the sliding end of the sliding rheostat 174 to slowly move downward, causing the resistance of the sliding rheostat 174 connected to the miniature infusion pump 8 to gradually decrease, thereby gradually increasing the delivery power of the miniature infusion pump 8. This allows the flushing force of the flushing fluid delivered by the miniature infusion pump 8 to gradually increase, giving the patient a certain adaptation period. During the downward movement of the insulating block 27, the detection block 28 is also driven downward simultaneously. During the downward movement of the detection block 28, the laser displacement sensor 175 will provide real-time feedback of the displacement value of the detection block 28 to the PLC controller 18. When the insulating block 27 drives the detection block 28 to move downward to the set distance, the PLC controller 18 will automatically control the miniature forward and reverse motor 172 to stop, so that the resistance of the sliding rheostat 174 no longer continues to decrease, thereby keeping the miniature infusion pump 8 running smoothly. The final set power is maintained to ensure that the rinsing fluid maintains a continuous and stable rinsing force to rinse the patient's nasal cavity. Before rinsing, medical staff can pre-set the initial position and the required downward distance of the detection block 28 through the PLC controller 18 according to the patient's condition, thereby pre-setting the final resistance value of the sliding rheostat 174 and the final output power of the micro infusion pump 8. This allows the output power of the micro infusion pump 8 to gradually change from weak to strong during the rinsing process, thus slowly increasing the rinsing force of the rinsing fluid to give the patient an adaptation process until the pre-set rinsing force is automatically reached. After the rinsing is completed, the PLC controller 18 controls the micro forward and reverse motor 172 to reverse, causing the lead screw 173 to reverse, which in turn causes the insulating block 27 to drive the sliding end of the sliding rheostat 174 and the detection block 28 to move upward. When the detection block 28 moves to the initial position, the PLC controller 18 will automatically stop the micro forward and reverse motor 172 under the detection feedback of the laser displacement sensor 175. During the filtration process, the ultraviolet germicidal lamp 131 sterilizes the rinsing liquid entering the filter box 10. Simultaneously, when the filter screen 12 becomes heavily clogged with undissolved particles in the rinsing liquid, its light transmittance weakens, consequently reducing the light penetration of the ultraviolet germicidal lamp 131. At this point, the total electrical signal value fed back to the PLC controller 18 by the various photosensitive sensors 132 drops to a certain range, causing the PLC controller 18 to automatically control the micro-stirring motor 141. The micro-stirring motor 141 controls the stirring blade 142 to rotate, which in turn controls the rotation of each vibration component 143. During the rotation of the vibration assembly 143, the vibrating balls 24 on it will intermittently contact and squeeze the protrusions 26. During the squeezing process between the vibrating balls 24 and the protrusions 26, the telescopic spring 25 will contract and store energy. After the vibrating balls 24 move away from the protrusions 26, the telescopic spring 25 will release energy, causing the vibrating balls 24 to strike the filter screen 12, causing the filter screen 12 to vibrate. The vibration force can help the filter screen 12 shake off the undissolved particles attached to it. At the same time, with the rotation of the stirring blade 142, the dissolution of the undissolved particles is accelerated. This not only avoids the waste of the agent, but also allows for the vibration cleaning of the filter screen 12, ensuring the filtration performance of the filter screen 12.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
