Description

Technical Field

[0001] This invention belongs to the field of otolaryngology medical device technology, specifically referring to a suction device for secretory otitis media. Background Technology

[0002] In the clinical diagnosis and treatment of secretory otitis media, middle ear effusion aspiration and drug infusion are the core treatment methods, and the performance of the aspiration equipment directly affects the safety and effectiveness of the treatment. In existing technologies, the aspiration and medication administration for secretory otitis media mostly rely on manual, step-by-step coordination by medical staff: the operator first uses an aspiration tool to extract the effusion from the middle ear cavity, and then uses a medication administration device to drip and infuse the therapeutic medication into the ear canal and the lesion in the middle ear. Throughout the entire operation, the amount of effusion extracted and the amount of medication injected depend entirely on manual experience, resulting in poor quantitative accuracy. At the same time, manual operation is prone to problems such as hand shaking and medication displacement, which can easily cause secondary damage to the ear canal and tympanic membrane, and may also lead to medication leakage and effusion residue, reducing the effectiveness of diagnosis and treatment. In addition, the step-by-step manual operation process is cumbersome, time-consuming and labor-intensive, significantly increasing the workload of medical staff.

[0003] Currently available ear aspiration devices use a negative pressure structure combined with a fixed-volume soft capsule to achieve rapid aspiration of effusion. They are easy to operate and have good stability in aspiration volume. However, the internal capacity of the soft capsule is a fixed value, which cannot flexibly adjust the aspiration volume and injection volume according to the patient's middle ear effusion volume and medication dosage. This makes it difficult to adapt to the clinical needs of patients with different conditions and age groups, and its application is quite limited. Therefore, it is necessary to propose a suction device for secretory otitis media to address the various technical deficiencies in the existing procedures for fluid aspiration and medication administration during the diagnosis and treatment of secretory otitis media. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides an aspiration device for secretory otitis media. A vertical and horizontal septum divides the main body of the device into two independent, non-communicating chambers. A medication guiding component and a negative pressure aspiration bladder are respectively located on opposite side walls of the vertical septum. When the user moves a control push handle, a connecting rod drives a rotating sealing disc to rotate. Simultaneously, the control push handle is pushed forward, and the connecting rod simultaneously drives a squeezing rod and a protruding rod to squeeze the negative pressure aspiration bladder. The protruding rod inserts the outer wall of the negative pressure aspiration bladder into a connecting hole, ensuring a tight fit between the inner wall of the negative pressure aspiration bladder and the medication guiding component. By adjusting the squeezing position of the protruding rod on the surface of the negative pressure aspiration bladder, the effective volume of the aspiration bladder can be changed, achieving stepless adjustment of the aspiration volume.

[0005] The technical solution adopted in this plan is as follows: This plan proposes an aspiration device for secretory otitis media, including a main body of the device. A rubber ball is fixedly installed at the end of the main body of the device, and the rubber ball communicates with the internal cavity of the main body of the device. A vertical partition is fixedly installed on the inner wall of the main body of the device, and the vertical partition divides the interior of the main body of the device into two independent chambers. A connecting hole is opened through the side wall of the vertical partition. A drug flow guide component is fixedly attached to one side wall of the vertical partition, and the drug flow guide component completely covers the connecting hole. A negative pressure suction bag is fixedly installed on the other side wall of the vertical partition away from the drug flow guide component. The negative pressure suction bag also covers the connecting hole. The drug flow guide component and the negative pressure suction bag are respectively located in the two independent chambers inside the main body of the device. The rubber ball communicates with the suction chamber inside the main body of the device in which the negative pressure suction bag is installed.

[0006] A support plate is fixedly installed on the side wall of the main body of the equipment, and a connecting rod is mounted through and rotatably on the support plate; one end of the connecting rod that extends into the interior of the main body of the equipment is fixedly connected to a squeezing rod, and the squeezing rod movably abuts against the surface of the negative pressure suction bladder.

[0007] As a further preferred embodiment of the present invention, the outer wall of the main body of the equipment is arranged vertically with drug storage bladders; a drug outflow pipe is connected to one end of the drug storage bladder near the main body of the equipment, the drug outflow pipe is embedded in the inner wall of the main body of the equipment, and the drug outlet end of the drug outflow pipe is arranged facing the drug flow guiding component; a drug outlet is opened at the end of the drug outflow pipe, the drug outlet is adjacent to the surface of the drug flow guiding component, and a sealing film is provided inside the drug outlet, the sealing film completely blocks the drug outlet.

[0008] Preferably, the drug storage bladder has a drug filling port at the end furthest from the main body of the equipment, and the drug filling port can be detachably fitted with a sealing cap.

[0009] Specifically, a rotating receiving groove is formed through the side wall of the support plate, and a rotating sealing disc is rotatably installed inside the rotating receiving groove, with the rotating sealing disc tightly fitting against the groove wall; a sliding receiving hole is formed through the side wall of the rotating sealing disc, and a connecting rod is slidably fitted into the sliding receiving hole, with the outer wall of the connecting rod in close contact with the hole wall; a control push handle is fixedly installed at one end of the connecting rod extending outside the main body of the equipment.

[0010] The squeeze rod is coaxially fixedly connected to the center of its side wall, and the length of the protrusion matches the width of the connecting hole. When the squeeze rod squeezes the negative pressure suction bladder, the protrusion presses the outer wall of the negative pressure suction bladder inward into the connecting hole, so that the inner wall of the negative pressure suction bladder is tightly fitted with the liquid guiding component.

[0011] Preferably, the negative pressure suction bladder is connected to a liquid guide tube on its side wall, and a lower end port is opened through the lower end of the main body of the equipment. An insert tube is coaxially fixedly installed inside the lower end port. The end of the insert tube closer to the inside of the main body of the equipment is connected to the liquid guide tube, and the end of the insert tube away from the main body of the equipment extends outward from the lower end port.

[0012] Furthermore, a horizontal partition is fixedly installed at the lower end of one side wall of the liquid flow assembly, and the outer edge of the horizontal partition is sealed to the inner wall of the main body of the equipment; the vertical partition cooperates with the horizontal partition to divide the internal space of the main body of the equipment into two non-communicating chambers.

[0013] Furthermore, the side wall of the vertical partition where the negative pressure suction bladder is installed has a scale printed along the length of the vertical partition. The scale is used to indicate the corresponding value of the effective liquid accumulation volume inside the negative pressure suction bladder when the protruding rod is in different compression positions.

[0014] Furthermore, the rotating sealing disc is made of sealing rubber; the main body and tubing are made of medical transparent plastic; the drug storage bladder is made of medical transparent soft plastic; and the negative pressure suction bladder and tubing are made of flexible medical silicone.

[0015] The beneficial effects achieved by this solution using the above structure are as follows: (1) The vertical and horizontal partitions divide the main body of the equipment into two independent chambers that are not connected to each other. The drug flow guide component and the negative pressure suction bag are placed on both sides of the vertical partition. Medical staff can push and push the control handle to drive the squeezing rod and the protruding rod to squeeze the negative pressure suction bag. By changing the squeezing position of the protruding rod, the effective volume of the negative pressure suction bag can be flexibly adjusted. The suction volume can be accurately set according to the amount of middle ear effusion of the patient, which can meet the clinical diagnosis and treatment needs of patients of different ages and different amounts of effusion. (2) Pressing the rubber ball can compress the air inside the device and squeeze the negative pressure suction bag; after inserting the cannula into the patient's ear canal, release the rubber ball, and the negative pressure suction bag will rebound to form a stable negative pressure, which can quantitatively extract middle ear effusion. The operation is simple, the aspiration quantitative accuracy is high, and the volume error caused by manual aspiration can be effectively avoided. (3) The rotating sealing disc is made of sealing rubber material, which can ensure that the main body of the equipment remains sealed during the entire process of the rotating sealing disc rotating in the rotating receiving groove and the connecting rod sliding in the sliding receiving hole, so as to ensure that the negative pressure suction bag can be stably squeezed when the rubber ball is pressed, and to continuously provide a reliable negative pressure suction effect. (4) Medical staff can remove the sealing cap in advance and fill different types of therapeutic drugs into the drug storage sac through the drug filling port. After filling, the sealing cap is closed again to achieve sealed storage of the drug solution. When medication is needed, the corresponding drug storage sac is pressed directly. The sealing film at the drug outlet is ruptured by the pressure, and the drug solution is transported along the drug outflow tube to the drug flow guide component. It is then directed to the ear canal and middle ear lesion through the connecting hole. This device integrates drug pre-storage and directional injection functions to solve problems such as uncontrolled dosage, drug position deviation, and drug leakage in traditional manual drug injection. The aspiration and injection functions are integrated to simplify the clinical operation process and reduce the workload of medical staff. Attached Figure Description

[0021] like Figures 1-9 As shown, the present invention provides an aspiration device for secretory otitis media, including a main body 1, a vertical partition 2, a negative pressure aspiration bladder 3, and a drug flow guiding component 4; the vertical partition 2 is fixedly installed on the inner wall of the main body 1, and the drug flow guiding component 4 is pasted and fixed to one side wall of the vertical partition 2; a through hole 22 is opened in the side wall of the vertical partition 2, and the drug flow guiding component 4 completely covers the through hole 22; the negative pressure aspiration bladder 3 is fixedly installed on the other side wall of the vertical partition 2 away from the drug flow guiding component 4, and the negative pressure aspiration bladder 3 also covers the through hole 22.

[0022] A horizontal partition 21 is fixedly installed at the lower end of one side wall of the liquid diversion component 4. The outer edge of the horizontal partition 21 is sealed and fitted to the inner wall of the main body 1 of the equipment. The vertical partition 2, together with the horizontal partition 21, divides the internal space of the main body 1 of the equipment into two non-communicating chambers. The liquid diversion component 4 and the negative pressure suction bag 3 are respectively arranged in the two independent chambers.

[0023] A rubber ball 11 is fixedly installed at the top of the main body 1 of the equipment. The rubber ball 11 is connected to the suction chamber of the negative pressure suction bag 3 installed inside the main body 1 of the equipment. A support plate 13 is fixedly installed on the side wall of the main body 1 of the equipment. A connecting rod 5 is rotatably mounted through the support plate 13. One end of the connecting rod 5 that extends into the inside of the main body 1 of the equipment is fixedly connected to a squeezing rod 52. The squeezing rod 52 is in movable contact with the surface of the negative pressure suction bag 3.

[0024] The center of the side wall of the squeezing rod 52 is coaxially fixed to the protruding rod 521, and the length of the protruding rod 521 is the same as the width of the connecting hole 22. When the squeezing rod 52 squeezes the negative pressure suction bag 3, the protruding rod 521 presses the outer wall of the negative pressure suction bag 3 into the connecting hole 22, so that the inner wall of the negative pressure suction bag 3 is tightly fitted with the liquid guiding component 4. The side wall of the vertical partition plate 2 is equipped with a scale 23 printed vertically along the side wall of the negative pressure suction bag 3. The scale 23 is used to indicate the effective liquid accumulation volume inside the negative pressure suction bag 3 corresponding to different squeezing positions of the protruding rod 521.

[0025] The negative pressure aspiration bag 3 has a fluid guide tube 31 connected to its side wall. The lower end of the main body 1 of the device has a lower end port 14. The lower end port 14 is coaxially fixedly installed with an insertion tube 32 inside. The end of the insertion tube 32 that is close to the inside of the main body 1 of the device is connected to the fluid guide tube 31. The outer end of the insertion tube 32 extends outward from the lower end port 14. The main body 1 of the device and the insertion tube 32 are both made of medical transparent plastic material, while the negative pressure aspiration bag 3 and the fluid guide tube 31 are made of flexible medical silicone material.

[0026] The outer wall of the main body 1 of the equipment is arranged in a vertical array of drug storage bags 12, which are made of medical transparent soft plastic. The end of the drug storage bag 12 near the main body 1 is connected to a drug outlet tube 121, which is embedded in the inner wall of the main body 1. The drug outlet end of the drug outlet tube 121 is arranged facing the drug flow guide component 4. A drug outlet 1211 is opened at the end of the drug outlet tube 121, which is close to the surface of the drug flow guide component 4. A sealing film 1212 is set inside the drug outlet 1211, which completely blocks the drug outlet 1211. A drug filling port 122 is opened at the end of the drug storage bag 12 away from the main body 1. The drug filling port 122 can be detachably fitted with a sealing cap 123.

[0027] A rotating receiving groove 131 is formed through the side wall of the support plate 13, and a rotating sealing plate 132 is rotatably installed inside the rotating receiving groove 131. The rotating sealing plate 132 is made of sealing rubber material and fits tightly against the groove wall of the rotating receiving groove 131. A sliding receiving hole 1321 is formed through the side wall of the rotating sealing plate 132, and the connecting rod 5 is slidably installed inside the sliding receiving hole 1321. The outer wall of the connecting rod 5 is in close contact with the hole wall of the sliding receiving hole 1321. A control push handle 51 is fixedly installed at one end of the connecting rod 5 that extends out of the main body 1 of the equipment.

[0028] Working principle and workflow Medical staff use this aspiration device to determine the required volume of fluid to be extracted based on the patient's ear canal condition and the total amount of middle ear effusion. The vertical partition 2 and the horizontal partition 21 divide the main body 1 of the device into two non-communicating chambers. The drug delivery component 4 and the negative pressure aspiration bladder 3 are located on both sides of the vertical partition 2. Medical staff move the control push handle 51, which drives the connecting rod 5 to rotate the rotating sealing disc 132. At the same time, the control push handle 51 is pushed forward, and the connecting rod 5 drives the squeezing rod 52 and the protruding rod 521 to squeeze the negative pressure aspiration bladder 3. The protruding rod 521 presses the outer wall of the negative pressure aspiration bladder 3 into the communicating hole 22. The squeezing position of the protruding rod 521 is adjusted with reference to the scale 23 on the vertical partition 2 to limit the effective capacity of the negative pressure aspiration bladder 3 and complete the preset aspiration volume. Medication pre-storage operation: Remove the sealing cap 123, and add the medication for secretory otitis media into the different medication storage sacs 12 through the medication inlet 122. After the addition is completed, close the sealing cap 123 again to seal and store the medication. When medication is needed clinically, press the corresponding medication storage sac 12 directly. The sealing film 1212 at the medication outlet 1211 will rupture under pressure, and the medication will be transported along the medication outflow tube 121 to the medication guiding component 4, and then guided to the patient's middle ear lesion through the connecting hole 22. Different medications can be selected according to the diagnosis and treatment needs, avoiding the problems of dosage loss and medication position deviation caused by manual on-site medication preparation and injection. Fluid aspiration procedure: The rubber bulb 11 is connected to the aspiration chamber equipped with the negative pressure aspiration bag 3. When medical staff press the rubber bulb 11, the air pressure inside the main body 1 of the equipment increases, and the negative pressure aspiration bag 3 contracts under the action of air pressure. Then, the intubation tube 32 is slowly inserted into the patient's ear canal, aligned with the middle ear effusion area, and the rubber bulb 11 is slowly released. The negative pressure aspiration bag 3 expands back after the external pressure is released, and a negative pressure is formed in the cavity. The middle ear effusion is aspirated along the intubation tube 32 and the drainage tube 31 into the negative pressure aspiration bag 3, completing the quantitative fluid aspiration. After the fluid is extracted, the drug storage bladder 12 can be pressed directly to carry out drug infusion; the fluid and drug can come into contact through the connecting hole 22. Medical staff can directly observe the internal fluid status through the transparent main body 1 of the equipment to judge the progress of diagnosis and treatment. The rotating sealing disc 132 is made of rubber sealing material, which can ensure the overall sealing of the equipment during the rotation and sliding of the connecting rod, and ensure that the internal air pressure is stable when the rubber ball 11 is pressed, maintaining a continuous and stable negative pressure suction effect. By repeating the above procedure, the aspiration treatment for multiple patients can be completed.
