Description

Ophthalmic liquid nebulizer {OPHTHALMIC LIQUID NEBULIZER}

The present invention relates to an ophthalmic liquid nebulizer, and more particularly, to an ophthalmic liquid nebulizer that adjusts the spray distance of the liquid liquid so that the particle size and spray amount of the liquid liquid desired by the user are sprayed to the eyeball.

Eye drops prescribed in the field of ophthalmology are provided for the treatment or prevention of ocular disease. Generally, these eye drops are in liquid form. Therefore, eye drops are generally used to administer eye drops to patients. The eye drop method is an eye drop administration method in which a liquid eye drop contained in a container is dripped from a nozzle provided at the tip of the container toward the surface of the eyeball.

Since the eyedropping method is to drop and supply liquid eyedrops to the surface of the eyeball, in conventional eyedroppers, the amount of eyedrops actually needed (generally about 1 μl to several μl) is more than the amount (usually about 30 μl to about 50 μl). ) of the eyedrops are dripped toward the ocular surface. Therefore, problems such as overflowing from the eye without being supported on the surface of the eyeball and being absorbed into the body through the tear duct have occurred. This problem not only causes economic loss due to the inability to efficiently administer relatively expensive eye drops, but also causes irritation of the skin by spilling the eye drops from the eyes and contacting the skin or the like in a certain type of eye drops, or the administration of more than the required amount of eye drops. As a result, there are problems such as causing unintended side effects. In addition, when the eye drop method was used, as described above, the eye drops overflowed from the eye or the patient had to face the face vertically upward during eye drop, which caused inconvenience in administration.

In order to solve the above problem, a method of making eye drops into spray-type drug liquid particles and spraying and supplying them to the surface of the eyeball (nebulizer) has been proposed.

The storage tank 210 is a container capable of storing a liquid medicine and may be disposed inside the main body 100 . The reservoir 210 may be formed of a material that does not change or damage components by reacting with the stored chemical solution. The reservoir 210 schematically shows only one reservoir 210 in the drawings, but two or more reservoirs 210 are provided to store two different types of drug solutions, and accordingly, different drug solutions are alternately or simultaneously administered. may also be possible. In addition, the storage tank 210 is manufactured in a replaceable manner so that the chemical solution can be changed as needed or replaced with a new storage tank 210 for storing a new chemical solution when the chemical solution is exhausted. In addition, the storage tank 210 may be manufactured to be disposable or reusable.

The atomizing means 220 is a means capable of spraying a chemical solution, and may form droplets from the chemical solution. The spray means 220 may be disposed inside the main body 100 and may come into contact with the liquid medicine stored in the storage tank 210 .

Accordingly, droplets of the liquid medicine formed by the spraying means 220 may be sprayed through the plurality of openings 231 of the mesh means 230 . At this time, the size of liquid droplets passing through the mesh means 230 may be limited to a size smaller than the diameter of the plurality of openings 231 .

The shape of the plurality of openings 231 may be a cylindrical shape having a circular cross section, but is not limited thereto. That is, the shape of the plurality of openings 231 may be a polygonal column shape having a polygonal cross section, or may be formed in a shape in which the cross section gradually widens or narrows in the depth direction.

The diameter of the droplet of the chemical solution may depend on the diameter of the plurality of openings 231 of the mesh means 230 . That is, when the diameter of the plurality of openings 231 is large, the diameter of the droplet increases, and when the diameter of the plurality of openings 231 is small, the diameter of the droplet decreases. At this time, the spraying mechanism composed of the spraying means 220 and the mesh means 230 forms and sprays droplets having an average diameter, but the sense of feeling the size of the particles may vary depending on the person, so the opening of the mesh means 230 It is required to control the size of droplets reaching the eyeball and the amount of liquid medicine reaching the eyeball without changing the diameter of 231. The ophthalmic liquid nebulizer 10 according to the present invention can solve these technical problems by adjusting the distance between the spray unit 200 and the eyeball using the drive unit 300.

6 is a cross-sectional view showing a driving unit 300 according to an embodiment of the present invention.

Referring to Figure 6, the drive unit 300 may reciprocate the spray unit 200 in one direction. For example, the driving unit 300 may move the spraying unit 200 back and forth in the spraying direction. That is, the drive unit 300 may move the spray unit 200 closer to the direction of the spray hole 110 of the main body 100, or move it in the opposite direction away from the spray hole 110 of the main body 100. . At this time, the driving unit 300 may be applicable to any means capable of providing driving force to the spraying unit 200, such as a motor and an actuator.

In one embodiment, the driving unit 300 may include a motor 310 and a rail 320 .

The rail 320 may extend from one end to the other end of the main body 100 along the reciprocating direction of the spray unit 200 . At this time, the reciprocating direction of the spraying unit 200 may preferably be the spraying direction of the chemical solution. A spray unit 200 including a storage tank 210, a spray unit 220, and a mesh unit 230 may be disposed above the rail 320. At this time, the spray unit 200 may further include a housing to accommodate the storage tank 210, the spray means 220 and the mesh means 230 and contact the rail 320 through the housing. Alternatively, the spray unit 220 and the mesh unit 230 may be connected to the reservoir 210, and the spray unit 200 may contact the rail 320 through the reservoir 210.

The motor 310 may rotate and move the spraying unit 200 in one direction, preferably back and forth in the spraying direction. In one embodiment, the motor 310 may be connected to the rail 320 through a gear. For example, a gear may be formed at one end of a rotating shaft of the motor 310, and a gear may also be formed at a portion where the rail 320 is connected to the motor 310. That is, the connection between the motor 310 and the rail 320 may have a rack-pinion gear structure. Accordingly, when the motor 310 rotates, the rail 320 may move forward and backward accordingly. In addition, the spray unit 200 connected to the rail 320 may move back and forth according to the movement of the rail 320 . In one embodiment, the upper surface of the rail 320 in contact with the gear of the motor 310 may be formed in a flat annular shape. Accordingly, when the motor 310 rotates, the rail 320 rotates and the spray unit 200 connected to the rail 320 may move.

In another embodiment, the drive unit 300 may include a handle and a rail 320 protruding from one side of the spray unit 200 to a sliding groove formed on one side of the main body 100. Specifically, the rail 320 extends from one end to the other end of the body 100 along the reciprocating direction of the spray unit 200, and the spray unit 200 may be movably disposed on the top of the rail 320. there is. At this time, a sliding groove parallel to the rail 320 may be formed on one surface of the main body 100 . The handle may protrude from one side of the spray unit 200 and protrude to the outside through the sliding groove of the main body 100. The user may move the handle protruding to the outside along the sliding groove of the main body 100 so that the spray unit 200 moves along the rail 320 .

The drive unit 300 according to the present invention is not limited to the above-described embodiment, and various means capable of moving the spray unit 200 may be employed. Hereinafter, for convenience of description, a case in which the driving unit 300 is composed of the motor 310 and the rail 320 will be mainly described.

Figure 7 is a cross-sectional view showing the position of the spray unit 200 according to an embodiment of the present invention. As described above, the ophthalmic liquid nebulizer 10 according to an embodiment of the present invention is provided with a driving unit 300 to adjust the injection position of the spraying unit 200. Accordingly, as shown in FIG. 7 , the size and amount of the chemical solution desired by the user can reach the eyeball.

Specifically, by adjusting the spraying position of the spraying unit 200, it is possible to reach the user's desired droplet size to the eyeball. The smaller the particle size of the droplet of the chemical liquid, the longer the stopping distance is formed and can be sprayed farther.

For example, when the spray unit 200 is positioned close to the nozzle 110 as shown in FIG. 7A, more droplets of larger particles may reach the eyeball. Accordingly, it is possible to satisfy a user who prefers the feeling of spraying the drug on the eyeball, that is, wants large-particle droplets of the drug solution to be sprayed on the eyeball.

For example, when the spray unit 200 is positioned away from the nozzle 110 as shown in FIG. 7B, more droplets of smaller particles may reach the eyeball. Accordingly, it is possible to satisfy a user who does not prefer the feeling of spraying the drug onto the eyeball, that is, wants small droplets of the drug solution to be sprayed onto the eyeball.

In addition, as the spraying position of the spraying unit 200 becomes farther from the spraying port 110, the effective spraying amount may decrease as shown in FIG. 7B. That is, as the injection position moves away from the spray hole 110, some of the spray amount of the chemical liquid may be blocked by the spray hole 110 and not sprayed to the outside. Accordingly, a user who does not prefer the feeling of the chemical solution being sprayed onto the eyeball can reduce the effective spray amount of the chemical solution effectively sprayed onto the eyeball by setting the spraying position away from the spray hole 110 .

When the user inputs the first position or the second position through the user interface 500, the user interface 500 transmits an input signal to the control unit 400. And the control unit 400 may control the position of the spray unit 200 to correspond to the signal input by the user.

In one embodiment, the user interface 500 may further display the third position as the position of the spray unit 200 . For example, the third position may be an intermediate point between the first position and the second position or any one point between the first position and the second position.

In one embodiment, the user interface 500 may display a movement menu so that the user can specifically adjust the spray position of the spray unit 200 . For example, the user interface 500 includes a first moving menu for moving the spray position of the spray unit 200 to the side of the spray hole 110 and a second move menu for moving the spray position of the spray unit 200 to the side opposite to the spray hole 110. can be displayed. The user can specifically adjust the spraying position of the spraying unit 200 by selecting the first moving menu or the second moving menu.

The user interface 500 may also output current information of the spray unit 200 . For example, the user interface 500 may output the position of the spray unit 200 on the rail 320 . In addition, the user interface 500 is designed so that the total spray amount of the chemical solution reaching the user's eyeball is the same, that is, the closer to the spray hole 110, the shorter spray time, and the farther from the spray hole 110, the longer spray time. , It is possible to output the spray time corresponding to the position of the spray unit 200. Accordingly, the user can check the current position and expected spraying time of the spraying unit 200 .

The control unit 400 may control the driving unit 300 according to a signal input from the user interface 500 . Here, the input signal may include the spray position of the spray unit 200 selected by the user in the aforementioned user interface 500 . In addition, the input signal may further include information on the calculated spraying time corresponding to the spraying position of the spraying unit 200 selected by the user so that the total amount of spraying the liquid reaching the user's eyeballs is the same.

In one embodiment, a user who prefers the feeling of spraying a liquid medicine on the eyeball may select the first position on the user interface 500 described above. At this time, the control unit 400 may control in the first mode when an input signal for the first position is provided. In the first mode, the control unit 400 controls the driving unit 300 to move the spray unit 200 to the first position, and the first spray corresponding to the total amount of spray reaching the eyeball of the user is the same. The chemical solution can be sprayed for a period of time.

Alternatively, a user who does not prefer the feeling of the liquid being sprayed onto the eyeball may select the second position on the user interface 500 described above. At this time, the control unit 400 can control in the second mode when an input signal for the second position is provided. In the second mode, the control unit 400 controls the drive unit 300 to move the spray unit 200 to the second position, and the second spray corresponding to the total amount of spray reaching the eyeball of the user is the same. The chemical solution can be sprayed for a period of time.

The control unit 400 may receive an input signal from the user interface 500 to control the driving unit 300 and the spray unit 200 and adjust the spray distance of the liquid medicine desired by the user. In addition, at the same time, the spraying time of the liquid medicine may be controlled so that the total dosage of the liquid liquid reaching the eyeball is the same even though the spraying positions of the spraying units 200 are different.

In one embodiment, the user may select a first movement menu or a second movement menu for moving the spray position of the spray unit 200 to the side of the spray hole or to the opposite side of the spray hole on the user interface. At this time, the control unit 400 may control the driving unit 300 so that the spray unit 200 moves a predetermined distance in the spray hole side direction or the opposite side direction according to the first movement or the second movement signal. Here, the predetermined distance may be, for example, a distance corresponding to 1/10 of the total distance that the spray unit 200 can move. In addition, the control unit 400 may determine a corresponding spraying time according to the final position of the spraying unit 200 and control the spraying unit 200 to spray the liquid medicine during the determined spraying time.
