Description

Technical Field

[0001] This invention belongs to the field of medical auxiliary device technology, specifically a mesenchymal stem cell exosome ocular atomization drug delivery device. Background Technology

[0002] Mesenchymal stem cells are progenitor cells widely found in various tissues and organs, possessing self-renewal and diverse differentiation potential. Cutting-edge regenerative medicine technologies can utilize mesenchymal stem cells to regenerate damaged tissues and organs, or to replicate the required tissues and organs in vitro for replacement therapy. Ocular medications can exert local and systemic therapeutic effects through the corneal and conjunctival routes, respectively. Currently, people use eye drops, which is not only inconvenient, but also makes it difficult to align the bottle nozzle with the eyeball and for the eye drops to enter the eye.

[0003] Ocular nebulization is an innovative ophthalmic treatment method. Its core lies in delivering medication directly to the eye through nebulization. The atomized drug particles are so small that they can penetrate the tear film and corneal epithelium on the surface of the eye, acting directly on the lesion. This effectively improves drug penetration and absorption in the eye, reduces drug waste and side effects, and enhances treatment efficacy.

[0004] The existing method of ocular nebulization is similar to intravenous drip administration. The eye drops are atomized before administration, and the distance between the nozzle and the eye is relatively large. Pollutants such as dust, smoke and bacteria in the environment can easily enter the eye with the atomized gas, causing infection or aggravating eye diseases. Constantly reducing the distance between the nozzle and the eye can easily contaminate the atomizing nozzle. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the technical solution adopted by this invention is: a mesenchymal stem cell exosome ocular atomization drug delivery device, comprising:

[0006] The body, the interior of which is equipped with an atomizer;

[0020] Furthermore, the disinfection mechanism includes:

[0021] A cleaning tank is located inside the machine body on the side away from the drug delivery mechanism.

[0022] Sponge boards, which are symmetrically arranged on the inner wall of the cleaning tank;

[0023] Cleaning rollers are symmetrically arranged at the bottom of the inner wall of the cleaning tank. The cleaning rollers are used to clean and disinfect the inner wall of the Y-shaped tube.

[0024] Furthermore, the disinfection mechanism also includes:

[0025] A disinfectant tank is located at the bottom of the machine body;

[0026] An air supply pipe is provided, the outer wall of which is connected to the outer wall of the disinfectant tank. A compression ball is provided at the end of the air supply pipe away from the disinfectant tank, and the compression ball is used to unidirectionally supply air to the disinfectant tank.

[0027] An elastic sheet is installed on the inner wall of the disinfectant tank, and the air inlet of the air supply pipe is located below the elastic sheet, so that the air in the disinfectant tank is squeezed upward from the bottom of the elastic sheet, and the top of the elastic sheet is filled with disinfectant.

[0028] Furthermore, the disinfection mechanism also includes:

[0029] A drive gear, which is mounted at the bottom of the machine body;

[0030] Driven gears are symmetrically arranged at the bottom of the machine body. The outer wall of the driven gear meshes with the outer wall of the driving gear, and the top of the driven gear is slidably connected to the bottom of the machine body.

[0031] The outlet pipe is symmetrically arranged on the top of the disinfectant tank. The outer wall of the outlet pipe away from the disinfectant tank is sleeved with the inner wall of the cleaning roller. The outer wall of the outlet pipe is sleeved with the inner wall of the driven gear. The outlet pipe is used to spray disinfectant into the Y-shaped tube.

[0032] Furthermore, the support component includes:

[0033] The insert rod has its outer wall fitted into the inner wall of the elliptical hole. The insert rod can slide inside the elliptical hole and rotate with the elliptical hole wall as a fulcrum. There are four insert rods, and the insert rods are rubber rods with a certain degree of elasticity.

[0034] The pressing tab is installed at the end of the insert rod away from the cover.

[0035] Furthermore, the support component also includes:

[0036] The V-shaped rod is installed at the end of the insert rod away from the pressing piece, and the V-shaped rod is located inside the cover.

[0037] An arc-shaped rod is located at the end of the V-shaped rod away from the insertion rod. The arc-shaped rod is used to separate the upper and lower eyelids of the human eye. The arc-shaped rod is made of medical-grade rubber.

[0038] Furthermore, the adjustment component includes:

[0039] The frame plate has two ends that are slidably connected to the inner wall of the cover, and the inner wall of the frame plate is sleeved with the outer wall of the Y-shaped tube. The frame plate is used to drive the dispensing end of the Y-shaped rod away from the human eye.

[0040] Furthermore, the adjustment component also includes:

[0041] A rubber ring is provided on the outer side of the middle part of the frame plate. The rubber ring is used to contact the bridge of the nose and maintain the distance between the frame plate and the eyes.

[0042] A spring is symmetrically arranged on the side of the frame plate away from the rubber ring, and the other end of the spring is connected to the inner wall of the cover.

[0043] The beneficial effects of this invention are as follows:

[0044] 1. This invention, by setting up a drug delivery mechanism, ensures that during nebulized drug delivery, the drug delivery end is close to the eyeball but will not poke the eye. After fixing the cover to the head, the user holds the support component close to the upper and lower eyelids, allowing the support component to open the eyelids, increasing the contact area between the nebulized liquid and the eyeball. During use, it remains isolated from the external environment, maintaining a closed drug delivery environment and reducing the risk of the eyeball coming into contact with dust in the air during indirect drug delivery, which could aggravate inflammation.

[0045] 2. This invention, through the installation of a disinfection mechanism, utilizes the rotation of cleaning rollers to thoroughly clean even the deepest parts of the Y-shaped tube. As the disinfectant flows out, it enters the inner wall of the casing. The casing is then manually shaken, allowing the sponge board to absorb the disinfectant and clean the inner wall. After cleaning, the disinfectant is drained, and the sponge board and cleaning rollers are removed, allowing the drug delivery device to be stored in the cleaning tank. This reduces dust adhesion and provides both internal and external cleaning and disinfection of the drug delivery device, enabling its long-term use and storage. The cleaning method is convenient and quick.

[0046] 3. This invention uses a support assembly with arc-shaped rods spaced far apart to open the eyelids before performing atomized treatment. This method opens the eyelids without touching the eyes, increasing the contact area between the eyeball and the atomized liquid, improving the atomization effect, increasing the actual effective absorption rate of the medication, and reducing the risk of other infections caused by human hand contact with the eyeball.

[0047] 4. This invention, through the setting of an adjustment component, first contacts the rubber ring at the bridge of the nose, causing the rubber ring to slide the frame plate towards the inner wall of the cover, thereby maintaining a certain distance between the frame plate and the eyeball. Then, the cover is fixed, avoiding direct contact between the eyeball and the Y-tube when the cover is worn directly, which could cause puncture. This also ensures that the dispensing end of the Y-tube is stably positioned close to the eyeball, reducing waste caused by the diffusion of the atomized medication. Attached Figure Description

[0057] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0058] Example 1, please refer to Figures 1-6 The present invention provides a technical solution: a mesenchymal stem cell exosome ocular atomization drug delivery device, which is described below.

[0059] include:

[0060] The main body 1 has an atomizer 3 installed inside it;

[0061] Connecting pipe 4 is installed on the outer wall of atomizer 3 and is a flexible tube.

[0062] The drug delivery mechanism 5 is located at the end of the connecting tube 4 away from the body 1. The drug delivery mechanism 5 is equipped with an elastic band that can be fixed to the head.

[0063] The mesenchymal stem cell exosome ocular nebulizer also includes:

[0064] Knob 2, which is located on the top of body 1;

[0065] The disinfection mechanism 6 is located inside the body 1 on the side away from the drug delivery mechanism 5.

[0066] During operation, the nebulizer 3 is filled with the medication and placed inside the main body 1. The main body 1 is turned on, allowing the nebulizer 3 to atomize the medication. The atomized medication then enters the medication delivery mechanism 5 through the connecting tube 4. The person holds the medication delivery mechanism 5 to their eyes and secures it to their head. The medication delivery mechanism 5 is manually opened to open the eyelids, increasing the contact area between the eyeball and the atomized medication. After use, the medication delivery mechanism 5 is disassembled and placed upside down inside the disinfection mechanism 6. The disinfection mechanism 6 is then manually squeezed to flush the inner wall of the medication delivery mechanism 5 with disinfectant. Finally, the disinfectant is discharged, and the medication delivery mechanism 5 is reconnected to the connecting tube 4. The medication delivery mechanism 5 is then placed inside the disinfection mechanism 6 for the next use.

[0067] Drug delivery device 5 includes:

[0068] Y-shaped tube 501 is connected to the end of connecting tube 4 away from body 1. Y-shaped tube 501 is a flexible tube.

[0069] Cover 502 is disposed on the outer wall of Y-tube 501, and the inner wall of cover 502 is sleeved with the outer wall of Y-tube 501.

[0070] Adjustment component 506 is disposed on the inner wall of housing 502. The adjustment component 506 is used to adjust the distance between Y-tube 501 and human eye.

[0071] Support components 505 are evenly arranged on the inner wall of the cover 502 and are used to open the upper and lower eyelids of a person.

[0072] The drug delivery device 5 also includes:

[0073] Connecting sleeve 503 is provided at the connection between connecting pipe 4 and Y-shaped pipe 501. Connecting sleeve 503 facilitates the disassembly and cleaning of Y-shaped pipe 501 and connecting pipe 4.

[0074] The cover 502 fits snugly against the face, allowing the atomized medicine to concentrate in the eyes and reducing dust contact with the eyes. The surface of the cover 502 is evenly provided with elliptical holes 504. The shape of the cover 502 is similar to a diving mask, which can fit snugly against the face.

[0075] Initially, after connecting the Y-tube 501 and the connecting tube 4 through the connecting sleeve 503, the atomized medicine from the nebulizer 3 enters the Y-tube 501 through the connecting tube 4. During use, the user holds the cover 502 and places it over the eyes. The adjustment component 506 first contacts the bridge of the nose. As the cover 502 approaches the face, it moves the medicine outlet of the Y-tube 501 away from the eyeball, ensuring that the medicine outlet is close to the eyeball without poking it. After fixing the cover 502 to the head, the user holds the support component 505 close to the upper and lower eyelids, opening the eyelids and increasing the contact area between the atomized liquid and the eyeball. Throughout the process, the user remains isolated from the external environment, maintaining a closed drug delivery environment and reducing the risk of increased inflammation caused by contact between the eyeball and dust in the air during drug delivery.

[0076] Disinfection facility 6 includes:

[0077] The cleaning tank 601 is located inside the body 1 on the side away from the drug delivery mechanism 5.

[0078] Sponge board 602 is symmetrically arranged on the inner wall of cleaning tank 601;

[0079] Cleaning rollers 603 are symmetrically arranged at the bottom of the inner wall of the cleaning tank 601. The cleaning rollers 603 are used to clean and disinfect the inner wall of the Y-shaped tube 501.

[0080] Disinfection facility 6 also includes:

[0081] Disinfectant tank 609 is located at the bottom of the body 1;

[0082] An air supply pipe 604 is provided, the outer wall of which is connected to the outer wall of the disinfectant tank 609. A squeeze ball 605 is provided at the end of the air supply pipe 604 away from the disinfectant tank 609. The squeeze ball 605 is used to unidirectionally supply air to the disinfectant tank 609.

[0083] An elastic sheet 610 is installed on the inner wall of the disinfectant tank 609. The air inlet of the air supply pipe 604 is located below the elastic sheet 610, so that the air in the disinfectant tank 609 is squeezed upward from the bottom of the elastic sheet 610. The top of the elastic sheet 610 is filled with disinfectant.

[0084] Disinfection facility 6 also includes:

[0085] The drive gear 608 is installed at the bottom of the body 1;

[0086] Driven gear 607 is symmetrically arranged at the bottom of the body 1. The outer wall of driven gear 607 meshes with the outer wall of driving gear 608. The top of driven gear 607 is slidably connected to the bottom of body 1.

[0087] The outlet pipe 606 is symmetrically arranged on the top of the disinfectant tank 609. The outer wall of the end of the outlet pipe 606 away from the disinfectant tank 609 is sleeved and fixed to the inner wall of the cleaning roller 603. The outer wall of the outlet pipe 606 is sleeved and fixed to the inner wall of the driven gear 607. The outlet pipe 606 is used to spray disinfectant into the Y-shaped pipe 501.

[0088] After atomization, the Y-tube 501 is removed from the connecting tube 4, and the drug delivery mechanism 5 is placed upside down into the cleaning tank 601, so that the two cleaning rollers 603 are inserted into the inside of the Y-tube 501. The squeeze ball 605 is manually pressed to allow air to enter the disinfectant tank 609 in one direction, and the disinfectant is squeezed out from the outlet pipe 606. At this time, the drive gear 608 rotates under the drive of the built-in drive of the machine body 1, which causes the driven gear 607 to rotate, thereby driving the outlet pipe 606 to rotate, and the cleaning rollers 603 also rotate.

[0089] After the disinfectant is squeezed into the Y-shaped tube 501, it is cleaned by the rotation of the cleaning roller 603, ensuring that even the deeper parts of the Y-shaped tube 501 are cleaned. As the disinfectant flows out, the disinfectant in the cleaning pool 601 enters the inner wall of the cover 502. At this time, the cover 502 is manually shaken so that the sponge plate 602 absorbs the disinfectant and cleans the inner wall of the cover 502. After cleaning, the disinfectant is discharged, and the sponge plate 602 and the cleaning roller 603 are removed, allowing the drug delivery device 5 to be placed in the cleaning pool 601 for storage, reducing dust adhesion. This process cleans and disinfects the drug delivery device 5 inside and out, enabling it to be used and stored for a long time. The cleaning method is convenient and quick.

[0090] Example 2, please refer to Figures 1-8 The present invention provides a technical solution: based on embodiment 1, the support component 505 includes:

[0091] Insert rod 5051, the outer wall of insert rod 5051 is sleeved with the inner wall of elliptical hole 504, insert rod 5051 can slide in elliptical hole 504 and rotate with elliptical hole 504 wall as fulcrum, four insert rods 5051 are provided, insert rod 5051 is a rubber rod with a certain elasticity.

[0092] Pressing plate 5052 is installed at the end of insert rod 5051 away from cover 502, and pressing plate 5052 is made of plastic.

[0093] Support component 505 also includes:

[0094] V-shaped rod 5053 is installed at the end of the insert rod 5051 away from the pressing piece 5052, and the V-shaped rod 5053 is located inside the cover 502;

[0095] The curved rod 5054 is located at the end of the V-shaped rod 5053 away from the insertion rod 5051. The curved rod 5054 is used to separate the upper and lower eyelids of the human eye. The curved rod 5054 is made of medical-grade rubber.

[0096] After securing the cover 502, the user places both hands on the pressing pads 5052, one above the other. The pressing pads 5052 are used as a set. Pushing the pressing pads 5052 causes the curved rods 5054 to adhere to the skin around the upper and lower eyelids. Then, the user pinches the pressing pads 5052, bringing them closer together and causing the curved rods 5054 to move away from each other, thus opening the eyelids. Nebulization treatment is then performed. This method opens the eyelids without touching the eyes, increasing the contact area between the eyeball and the nebulized liquid, improving the nebulization effect, increasing the actual effective absorption rate of the medication, and reducing the risk of other infections caused by hand contact with the eyeballs.

[0097] Adjustment component 506 includes:

[0098] The frame plate 5061 has two ends that are slidably connected to the inner wall of the cover 502. The inner wall of the frame plate 5061 is sleeved with the outer wall of the Y-shaped tube 501. The frame plate 5061 is used to drive the dispensing end of the Y-shaped rod away from the human eye.

[0099] The regulating component 506 also includes:

[0100] Rubber ring 5062 is located on the outer side of the middle part of the frame plate 5061. The rubber ring 5062 is used to contact the bridge of the nose and maintain the distance between the frame plate 5061 and the human eye.

[0101] Spring 5063 is symmetrically arranged on the side of the frame plate 5061 away from the rubber ring 5062, and the other end of spring 5063 is connected to the inner wall of the cover 502.

[0102] When the cover 502 is brought close to the face, the bridge of the nose first contacts the rubber ring 5062, causing the rubber ring 5062 to drive the frame plate 5061 to slide towards the inner wall of the cover 502, thereby maintaining a certain distance between the frame plate 5061 and the eyeball. Then the cover 502 is fixed to prevent the eyeball from directly contacting the Y-tube 501 when the cover 502 is worn, which could cause puncture. This also ensures that the dispensing end of the Y-tube 501 can be stably placed close to the eyeball, reducing waste caused by the diffusion of the atomized medicine.

[0103] The specific workflow is as follows:

[0104] During operation, the nebulizer 3 is filled with liquid medication and placed inside the body 1. After connecting the Y-tube 501 and the connecting tube 4 through the connecting sleeve 503, the body 1 is turned on. The liquid medication atomized by the nebulizer 3 enters the Y-tube 501 through the connecting tube 4. When in use, the user holds the cover 502 and places it over the eyes. The adjustment component 506 first contacts the bridge of the nose. As the cover 502 approaches the face, it moves the medication outlet of the Y-tube 501 away from the eyeball, ensuring that the medication outlet is close to the eyeball but does not poke it. After fixing the cover 502 to the head, the user holds the support component 505 close to the upper and lower eyelids, which opens the eyelids and increases the contact area between the atomized liquid and the eyeball. During use, the user is kept isolated from the external environment to maintain a closed medication environment.

[0105] Remove the Y-tube 501 from the connecting tube 4, and place the drug delivery mechanism 5 upside down into the cleaning tank 601. Insert the two cleaning rollers 603 into the inside of the Y-tube 501. Manually press the squeeze ball 605 to allow air to enter the disinfectant tank 609 in one direction. The disinfectant is squeezed out from the outlet pipe 606. At this time, the drive gear 608 rotates under the drive of the built-in drive of the machine body 1, which causes the driven gear 607 to rotate, thereby driving the outlet pipe 606 to rotate, and the cleaning rollers 603 also rotate.

[0106] After the disinfectant is squeezed into the Y-shaped tube 501, it is cleaned by the rotation of the cleaning roller 603, so that even the deeper parts of the Y-shaped tube 501 can be cleaned. As the disinfectant flows out, the disinfectant in the cleaning pool 601 enters the inner wall of the cover 502. At this time, the cover 502 is manually shaken so that the sponge plate 602 absorbs the disinfectant and cleans the inner wall of the cover 502. After cleaning, the disinfectant is discharged, the sponge plate 602 and the cleaning roller 603 are removed, and the drug delivery mechanism 5 is placed in the cleaning pool 601 for storage.
