EYE NEBULIZER

Abstract

The eye nebulizer deploys at least a block piece along a tube for the nebulized medication so as to achieve an S-shaped flow path, thereby preventing the nebulized medication from directly impacting and injuring the eye. In addition, due to the altered and curved flow path, the nebulized medication would diffuse around the rim of the eye cup, thereby covering a wider treatment area around the eye. The eye nebulizer therefore achieves an enhanced treatment effect and a greater applicability.

Claims

1. An eye nebulizer, comprising a nebulization unit, an eye cup, and a tube respectively connecting the eye cup and the nebulization unit, wherein the nebulization unit comprises a main member, a reservoir member configured on the main member and storing a medication, a vibrator module inside the main member for nebulizing the medication stored in the reservoir member, and a nozzle configured on the main member and connecting the tube to release the nebulized medication; and the tube comprises a channel connecting the nozzle and the eye cup, a wall surrounding the channel, and at least a block piece inside the channel configured on the wall and forming an S-shaped flow path for the nebulized medication flowing through the channel.

2. The eye nebulizer according to claim 1, wherein the tube has a curved and elongated shape.

3. The eye nebulizer according to claim 1, wherein there are at least two block pieces configured at intervals along the channel.

4. The eye nebulizer according to claim 1, wherein at least a block piece is integrally formed with the tube and fixedly attached to the wall.

5. The eye nebulizer according to claim 3, wherein at least one of the block pieces is integrally formed with the tube and fixedly attached to the wall.

6. The eye nebulizer according to claim 3, wherein at least one of the block pieces is detachably plugged into the wall.

7. The eye nebulizer according to claim 2, wherein there are at least two block pieces configured at intervals along the channel.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] The following descriptions are exemplary embodiments only, and are not intended to limit the scope, applicability or configuration of the invention in any way. Rather, the following description provides a convenient illustration for implementing exemplary embodiments of the invention. Various changes to the described embodiments may be made in the function and arrangement of the elements described without departing from the scope of the invention as set forth in the appended claims.

[0015] As shown in FIG. 2, an eye nebulizer 3 according to an embodiment of the present invention includes a nebulization unit 31, an eye cup 32, and a tube 33 respectively connecting the eye cup 32 and the nebulization unit 31. The nebulization unit 31 includes a main member 311, a reservoir member 312 configured on the main member 311 and storing a medication (not shown), a vibrator module 313 (indicated by the dotted box) inside the main member 311 for nebulizing the medication stored in the reservoir member 312, and a nozzle 314 configured on the main member 311 and connecting the tube 33 to release the nebulized medication.

[0016] The tube 33 has a channel 332 surrounded by a wall 331 and connecting the nozzle 314 so as to allow the nebulized medication to pass through. The tube 33 has a curved and elongated shape. Inside the channel 332, there is at least a block piece 333 on the wall 331 to interfere and shape a flow path of the nebulized medication passing through the channel 332. As shown in FIGS. 3 and 4, there are two block pieces 333, one fixedly attached to and one detachably plugged into the wall 331. Alternatively, as shown in FIGS. 5-1 and 5-2, the block pieces 333 are all integrally formed with the tube 33 and fixedly configured on the wall 331 By configuring multiple block pieces 333 of various shapes and directions at intervals on the wall 331 along the channel 332, various types of flow paths, such as S-shaped flow paths, may be formed so as to adapt to the different pressures from the nebulization unit 31 and the different amounts of nebulized medications.

[0017] As shown in FIGS. 3 and 6, to operate the eye nebulizer 3, a required medication (or water or saline solution) is first placed in the reservoir member 312. The reservoir member 312 is then joined to the main member 311. The vibrator module 313 is engaged to shake the reservoir member 312. The medication (or water or saline solution) is nebulized into a mist and the mist is sprayed through the nozzle 314. As the mist flows through the tube 33, it is interfered and blocked by the block pieces 333 and then finally applied to the eye covered by the eye cup 32. Due to the curvature of the tube 33 and the alternately configured block pieces 33, a direct flow path of the mist is altered into a curved flow path, thereby preventing the mist from directly impacting and injuring the eye. In addition, due to the altered and curved flow path, the mist would diffuse around the rim of the eye cup 32, thereby covering a wider treatment area around the eye. Foreign object or debris attached to the tube 33 or the nozzle 314 would be blocked by the block pieces 333 and the curved tube 33, again preventing the eye from being injured.

[0018] In summary, the eye nebulizer achieves a curved flow path (e.g., an S-shaped flow path) by employing a curved tube and configuring one or more block pieces along the tube so as to protect the eye and cover a wider treatment area.

[0019] While certain novel features of this invention have been shown and described and are pointed out in the annexed claim, it is not intended to be limited to the details above, since it will be understood that various omissions, modifications, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing in any way from the claims of the present invention.
