Description

Technical Field

[0001] The invention relates to the technical field of ear bath therapy, in particular to an integrated drug administration and leakage prevention device for ear bath therapy. Background Art

[0002] Ear bathing is a local treatment for ear diseases. During the treatment, the patient is required to lie on his side with the affected ear upwards and maintain this position for at least 15-20 minutes, which greatly affects the patient's normal behavior and activities. The present invention aims to solve the problem of patients having difficulty in independently dropping medicine and being unable to move freely during the entire ear bathing process by designing an integrated drug delivery and leakage-proof device for ear bathing treatment.

[0003] Ear bath therapy is mainly used clinically for acute and chronic otitis externa, otitis media, ear canal eczema, and fungal otitis externa. The specific steps include:

[0004] (1) Wipe away the pus and secretions with a sterilized cotton swab or use 3% hydrogen peroxide to thoroughly clean the pus and secretions in the external auditory canal and the ear cavity.

[0005] (2) After rinsing, clean the external auditory canal with a sterilized cotton swab.

[0006] (3) Drop the medicine into the ear canal and soak it for more than 15 minutes to allow the ear mucosa to fully absorb the medicine, thereby achieving the purpose of local treatment.

[0007] (4) Finally, change the body position to allow the liquid medicine to flow out.

[0008] Otitis media and otitis externa are common childhood diseases. For children, the ten-minute waiting period for a regular medicinal bath is boring and long. They are lively and active, which can easily cause the medicine to leak out. At the same time, the medicine dripping process requires the assistance of others, otherwise it is easy to leak out and is extremely inconvenient.

[0009] When using the integrated drug delivery and leakage prevention device for ear bath treatment, patients can independently and accurately administer medication through the product's infusion tube device, while effectively preventing medication leakage, allowing them to move freely during the ear bath, greatly alleviating the inconvenience caused by ear bath treatment.

[0010] To this end, we propose an integrated drug delivery and leakage-proof device for ear bath therapy. Summary of the Invention

DETAILED DESCRIPTION

[0058] To make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0059] The present invention provides an integrated anti-leakage device for ear bath therapy. It has a bionic vascular valve one-way valve design to prevent the backflow of the drug solution. Combined with the tightness of the ear plug, it can ensure the patient's free movement during the ear bath. The built-in infusion tube is designed with a 3 / 4 cylindrical cross-section to balance the air pressure inside and outside the ear canal, reducing the discomfort caused by the pressure difference during the drug dripping process. Please refer to the Figure 1-7 , comprising a shell body 1 and an infusion tube body 2;

[0060] The shell body 1 can be inserted into the patient's ear and can seal the ear canal to block the outflow of the medicine. At the same time, the shell body 1 is set to medical silicone, which can play a fixing role, seal the ear canal, block the outflow of the medicine, and through the design of the one-way valve principle, it can ensure that the medicine can stay in the external auditory canal for a long time during the patient's free activities after administration, thereby ensuring the dosage and absorption effect of the medicine. The shell body 1 includes: a shell tail component 11, a shell tail 111, an infusion tank 112, a shark fin ear support 11, a shell head component 12, a middle tube 121, a shell head 122, a first bionic vascular valve one-way valve 123 and a leak-proof layer 13, the shell tail component 11, It is arranged at the upper end of the shell body 1, and the infusion tube body 2 can be inserted into the interior. The shell tail 111 is arranged at the upper end of the shell tail component 11 and is arranged in an irregular elliptical shape. The shell tail 111 is in contact with the external auditory canal. The infusion groove 112 is arranged at the top of the shell tail 111 and can be inserted into the infusion tube body 2. The shark fin ear support 113 is arranged at the rear end of the outer wall of the shell tail 111, and the shark fin ear support 113 can be buckled into the antihelix and fit tightly with the antihelix. The shell head component 12 is connected to the lower end of the shell tail component 11, and can clamp the lower end of the infusion tube body 2 inside, and can block the liquid medicine in one direction, and can The infusion tube body 2 can be pressed down to make the liquid medicine overflow the bottom of the shell head assembly 12, the middle tube 121 is connected to the bottom of the shell tail 111 and communicated with the shell tail 111, the shell head 122 is connected to the bottom of the middle tube 121 and communicated with the middle tube 121, and the shell head 122 cooperates with the middle tube 121, adopting two cylindrical structures with different inner diameters, which are narrow at the bottom and wide at the top, and can clamp the telescopic component 23 of the infusion tube body 2. The first bionic vascular valve one-way valve 123 is arranged at the bottom of the shell head 122, and has three groups of valves cooperating with each other to block the liquid medicine, and cooperate with the infusion tube body 2 to push the liquid medicine into the ear canal. When the infusion tube 221 is connected to the ear drop bottle and pushed in together with the ear drop bottle, the first bionic vascular valve one-way valve 123 of the shell head 122 is pushed open by the dropper and deformed, and at the same time the medicine flows into the external auditory canal from the opening for administration. When the ear drop bottle is pulled out from the connection of the infusion tube 221, the first bionic vascular valve one-way valve 123 closes and returns to its original state, effectively preventing the drug from leaking. The design of this one-way valve principle can ensure that the drug can stay in the external auditory canal for a long time during the patient's free activities after administration, thereby ensuring the dosage and absorption effect of the drug. The leak-proof layer 13 is arranged in the middle of the outer wall of the shell head assembly 12 and is arranged in a truncated cone shape, and can completely close the ear canal.

[0061] The infusion tube body 2 is detachably mounted inside the shell body 1, and the ear drops required for ear bathing can be gently inserted into the interior of the infusion tube body 2 after the lid is opened, so that the medicine enters between the infusion tube body 2 and the shell body 1, and then by gently squeezing the ear drop bottle and gently pressing the infusion tube body 2, the medicine flows into the external auditory canal through the long tube. The infusion tube body 2 cooperates with the shell body 1 to inject the medicine into the interior of the ear canal, and the built-in infusion tube cross-section 3 / 4 cylindrical design is used to balance the air pressure inside and outside the ear canal, reducing the discomfort caused to the patient by the pressure difference during the medicine dripping process. The infusion tube body 2 includes: an infusion tube tail assembly 21, an extension tube 211, a tapered tube 212, a second bionic vascular valve one-way valve 213, an infusion tube assembly 22, and an infusion tube 22. 1. External air pressure groove 222, telescopic component 23, telescopic cone 231 and cone groove 232, infusion tube tail component 21, which is arranged at the upper end of the infusion tube body 2, and the bottle of ear drops required for ear bath can be inserted into the interior for filling operation, extension tube 211, which is arranged at the top of the infusion tube tail component 21, and can be inserted by the bottle of ear drops required for ear bath, tapered tube 212, which is arranged at the bottom of the extension tube 211 and is connected to the extension tube 211, the second bionic vascular valve one-way valve 213, which is arranged between the extension tube 211 and the tapered tube 212, and the second bionic vascular valve one-way valve 213 cooperates with the first bionic vascular valve one-way valve 123 to push the ear drops required for ear bath into the lower end and make the ear drops required for ear bath Overflowing the first bionic vascular valve one-way valve 123, so that the ear drops needed for ear bathing flow into the external auditory canal, wherein the design of the second bionic vascular valve one-way valve 213 is also adopted between the extension tube 211 and the tapered tube 212. Since the diameters of the ear dropper tips commonly used on the market are different, this design can be connected with most ear drops, covering a wide range of diseases and having a wide range of applications. At the same time, it also ensures the safety and environmental protection of the drug administration process. The cross-section of the infusion tube 221 adopts a 3 / 4 circular design. When the infusion tube breaks through the valve, the remaining 1 / 4 circle gap is used to empty the air and balance the air pressure in the ear canal. The entire infusion tube cavity is divided into 3 / 4 and 1 / 4 through an L-shaped partition plate, wherein the 3 / 4 lumen is used to extend upward to connect the ear drop bottle, Ear drops are injected into the ear, and the remaining 1 / 4 space is used for upward ventilation to ensure that the ear pressure is the same as the atmospheric pressure, so that the injection is smooth. The infusion tube component 22 is connected to the bottom of the infusion tube tail component 21, and can store the liquid medicine inside. It can also cooperate with the middle tube 121 and the shell head 122 to push the liquid medicine out of the first bionic vascular valve one-way valve 123 until it drips into the interior of the ear canal. The infusion tube 221 is connected to the bottom of the tapered tube 212 and communicates with the tapered tube 212. It can store the liquid medicine inside, and the upper end is blocked by the second bionic vascular valve one-way valve 213, and the lower end is blocked by the first bionic vascular valve one-way valve 123. The external air pressure groove 222 is set at the front end of the infusion tube 221 and is set to a gap of one-quarter of a cylinder.The gap can be emptied when pressed down, so that the air balances the air pressure in the ear canal. The telescopic component 23 is slidably connected to the lower end of the outer wall of the infusion tube component 22 and can be clamped by the shell head 122. It can telescope and push the liquid tube component 22 to push the liquid medicine into the external auditory canal. The telescopic truncated table 231 is slidably connected to the lower end of the outer wall of the infusion tube 221 and can be clamped by the shell head 122. It can slide the infusion tube 221. The truncated table groove 232 is provided at the front end of the telescopic truncated table 231. Cooperating with the external air pressure groove 222, the air in the ear canal is evacuated through the gap, allowing the air to balance the air pressure in the ear canal. The telescopic assembly 23 uses two cylindrical structures with different inner diameters, narrow at the bottom and wide at the top. By pushing the inner cylinder to move, when the inner diameter of the inner cylinder equals the outer cylinder, resistance is generated and the upper limit of the telescopic movement is reached. At this time, the infusion tube breaks through the valve at the head, allowing for drug delivery. When retracted, the closed structure at the tail prevents the inner cylinder from falling out, thus achieving the telescopic function.

[0062] Through multiple tests and experiments, we found that if the cross-section is only 1 / 2 circle, the overall structure will not be supportive enough and will easily collapse when inserted into the ear canal, causing the overall structure's elasticity to be hindered. If the cross-section is only 1 / 8, 1 / 16 circle or smaller, due to the small gap, the gas emptying speed is limited. When the medicine drips in too quickly, it will generate greater pressure in the ear, causing discomfort to the patient. For patients with ear canal diseases such as otitis media, this pain is more acute. When the cross-section is 1 / 4 circle, it can meet better support and the gas can be discharged faster through the gap. Therefore, the infusion tube 221 adopts a design with a 3 / 4 circle cross-section.

[0063] During specific use, those skilled in the art will clean the external auditory canal to ensure the cleanliness and hygiene of the drug administration process, slightly lift the upper edge of the auricle with the hand until the size of the auricle can accommodate the shark fin ear support 113 outside the shell tail 111, slowly put the shell body into the ear canal and ensure that the shark fin ear support 113 is obliquely buckled into the antihelix, use the fingers to press and slowly push inward until the shell body completely closes the external auditory canal, further press the shark fin ear support 113 of the shell tail 111 into the auricle, then rotate counterclockwise to fix the front of the device in the ear, so that the leak-proof layer 13 and the shell tail 111 cooperate with each other to completely close the external auditory canal, open the cover of the ear drops needed for ear bath and gently insert the extension tube 211 to connect the medicine bottle part to ensure that the second bionic vascular valve is opened on the top of the ear drop tube The membrane one-way valve 213 enters the inside of the 3 / 4 circle infusion tube 221, and then the ear drop bottle is gently squeezed to allow the medicine to be poured into the inside of the infusion tube 221, and then the extension tube 211 is pressed to make the first bionic vascular valve one-way valve 123 cooperate with the second bionic vascular valve one-way valve 213, and the first bionic vascular valve one-way valve 123 is pushed open to allow the medicine to flow into the external auditory canal. After the medication is completed, the ear drop bottle is pulled out and the ear bath treatment is started. During this process, the first bionic vascular valve one-way valve 123 of the shell head 122 can prevent the medicine from flowing back and keep it in the external auditory canal. The patient can move freely. After the ear bath is completed, the shell body 1 is rotated clockwise to make the shark fin ear support 113 fall out of the auricle, and the device is gently removed. After rinsing with clean water, it can be disinfected with alcohol and reused.
