Description

Device for obtaining micro-droplets

The present invention relates to a device for obtaining trace droplets, especially a device for obtaining trace eye drops from a drip opening.

In recent years, the safety of children's medication has attracted more and more attention from society. Children are more sensitive to the drug dose response, and the drug dose should be different for different ages, or the same age and different weights. Too little drug can not achieve the therapeutic effect, and too much drug will increase side effects. However, general liquid medicines (especially bottled eye drops) cannot be reduced according to the age or weight of patients, resulting in no corresponding medicine dosage for children. Specifically, a drop of bottled eye drops is about 30-50 microliters, which is more than the amount required by ordinary people, especially the corresponding amount for young children. Long-term use of excessive eye drops in children may cause side effects such as increased intraocular pressure, allergies, photophobia or aggravation of eye discomfort.

Currently, there is a lack of a simple device, which can provide the user to obtain a small amount of liquid medicine, and can ensure the convenience and safety of use. In particular, there is a lack of an improved device that allows children to obtain tiny amounts of eye drops to get the best treatment for their eyes.

For this reason, the main purpose of the present invention is to provide a device that can be used to provide users (such as children) to obtain micro-droplets (such as eye drops), and the obtained micro-droplets can be affected by adhesion and surface tension. The suspension is formed to provide users with use, and can ensure the convenience and safety of use. The present invention further provides a method for obtaining micro-droplets, which can facilitate users (such as children) to obtain required micro-droplets from a container (such as an eye drop bottle).

The device for obtaining micro-droplets of the present invention includes a body and a storage space. The body has a surface capable of receiving liquid droplets. The storage space is formed on the surface of the main body and can only retain 0.1-95% of the total volume of the droplets.

In one embodiment, the main body is a column, and one end of the main body is combined with a grip for the user to hold.

In one embodiment, the rear end of the main body is provided with a coupling part, the extending direction of the coupling part is substantially perpendicular to the extending direction of the main body, and a handle is coupled to one end of the coupling part for the user to hold. The main body is preferably made of non-absorbent foam, and the whole of the main body and the joint part forms an L-shaped section.

In one embodiment, the storage space is a groove recessed from the surface of the body, the surface of the body is a flat surface, and the diameter of the flat surface is less than 6 mm and preferably between 1 to 5 mm. The diameter is between 1 and 4 mm, and the depth of the groove is between 0.5 and 1 mm.

The other objectives, advantages and features of the present invention will be understood from the detailed description of the following preferred embodiments with reference to the accompanying drawings.
