Description

TECHNICAL FIELD The present invention relates to an eyedropping aid used when eyedrops are instilled into the eye.

The eye drops are filled in a small bottle for eye drops made of resin, and the person who receives the eye drops holds the bottle for eye drops by hand and drips the eye drops into the eyes from directly above the eyes. . In order to drip the eye drops, it was necessary to keep the eyes open, avoid the eyelids and eyelashes, and ensure that the eye drops were dripped into the eyes, which was not an easy task. Also, since the amount of eye drops to be dripped corresponds to the strength with which the bottle for eye drops is pushed by hand, if the bottle for eye drops is pushed too hard, a large amount of the eye drops will be dropped and the liquid will be wasted. There was also

As described above, various problems have been raised regarding eye drops, and conventionally, there have been proposals for better application of eye drops.
For example, Patent Literature 1 describes an eye medicine spray supply device that atomizes an eye medicine in an atomizing part to form mist-like medicine particles, and sprays and supplies the medicine toward the eyeball surface of a patient. According to the eye medicine spray supply device described in Patent Document 1, the eye drops can be administered to the patient more easily than before by spraying the eye drops toward the eyeball surface of the patient.

Japanese Patent No. 5145514

However, the eye medicine spray supply device described in Patent Literature 1 atomizes eye medicine with an ultrasonic oscillator, and requires a drive source for vibrating the ultrasonic oscillator, etc., and is very large-scale. The device is configured.
Normally, an eyedrop bottle filled with eyedrops is disposable in order to prevent contamination with germs. Since it requires a driving source, etc., it is expensive and is expected to be used repeatedly. Therefore, since cleaning and the like are necessary for repeated use, it is expected to be used in medical institutions and the like, and cannot be easily used by patients on a daily basis.

SUMMARY OF THE INVENTION An object of the present invention is to provide an eye drop aid that can administer eye drops with a simpler configuration than before without imposing a burden on a patient.

The eye-dropping aid of the present invention is an eye-dropping aid that is attached with an eye-dropping medicine bottle and administers eye drops filled in the eye-dropping medicine bottle to the eye of a patient.
As a configuration,
a container capable of accommodating an eyedrop medicine bottle inside;
a holding member that holds the eyedrops bottle in close contact with the periphery of the eyedrops bottle housed inside the container, with the tip of the eyedrops bottle having the eyedrops ejection port positioned downward;
an injection mechanism part for sucking up the eye drops from the discharge port of the bottle for eye drops held by the holding member and spraying the sucked liquid medicine in the form of mist from a nozzle arranged outside the container.

According to the present invention, it is possible to easily inject the eye drops into the eye of the patient just by operating the injection mechanism part after storing the bottle for the eye drops, and administering the eye drops in a comfortable posture. Become. In this case, since the eye drop aid of the present invention accommodates the eye drop bottle in the container, it is not necessary to transfer the eye drop from the eye drop bottle, and the eye drops can be easily applied to the patient's eye with a relatively simple configuration. Since it can be jetted, it can also be disposable.

BEST MODE FOR CARRYING OUT THE INVENTION An eye drop aid according to an embodiment (hereinafter referred to as "this example") of the present invention will now be described with reference to the accompanying drawings.

The figure is a front view showing the eye drop aid 100 of this example.
The eye drop aid 100 is composed of a container 110 in which the eye drop bottle 200 can be stored, a lid 120 attached to the upper side of the container 110 so as to be openable and closable, and an injection mechanism 140 attached to the lid 120 .

The container 110 is made of, for example, a transparent resin, and has a spiral groove 111 for attaching the lid 120 to the upper portion thereof. When the lid 120 is attached to the container 110, the inside of the container 110 is brought into close contact.
The configuration in which the lid 120 is screwed onto the container 110 is merely an example, and the lid 120 may be attached in another configuration. Further, forming the container 110 from a transparent resin is an example, and it may be formed from an opaque resin. In addition, the surface of the container 110 may be provided with a depression that fits when the user holds the eye drop aid 100 by hand.

An injection mechanism 140 is attached to the upper portion of the lid 120 (outside the container 110). A base portion 141 of the injection mechanism portion 140 is attached to an attachment hole 121 in the center of the lid 120 by screwing or the like.
A protruding member 142 having a nozzle 143 on its side surface is arranged on the base portion 141 of the injection mechanism portion 140, and the upper end 142a of the protruding member 142 is pushed downward (in the direction of the arrow M), thereby causing the injection into the container 110. Eye drops are sucked up from the attached bottle 200 for eye drops, and the sucked up eye drops are sprayed from nozzles 143 in the form of mist. The projection member 142 can be rotated, and the position of the nozzle 143 can be adjusted by rotating the projection member 142 .

The eyedrop medicine bottle 200 mounted in the container 110 is placed above (below in FIG. 1) a cylindrical medicine solution reservoir 210 with a diameter of about 1.5 cm to 2 cm, as shown by a phantom line in FIG. A tapered cap attachment portion 220 is formed, and an eye dropper 230 is attached to the tip of the cap attachment portion 220 .
An eye drop is taken out from a hole 231 formed in the eye drop port 230 . In FIG. 1, the eye drop medicine bottle 200 is shown upside down. There are various sizes and shapes of the eyedrop medicine bottle 200, and the size shown in FIG. 1 is an example.
As shown in FIG. 1, the eyedrops bottle 200 configured as described above is inserted into the holes 132 and 133 of the resin member 130 as the holding member with the eyedropper port 230 of the cap attachment portion 220 directed downward. be.

The resin member 130 is molded from a flexible material such as silicon, and has a cylindrical hole 132 and a conical hole 133 continuous with the cylindrical hole 132 . Furthermore, the narrowest part of the conical hole 133 has a pore 134 connected to the conical hole 133 .
The periphery of the pore 134 is a stepped portion 131 in which the diameter of the resin member 130 is reduced.
The resin member 130 may be made of a material having flexibility at least around the holes 132 and 133, and the other portions may be made of hard resin or the like.

The cylindrical hole 132 of the resin member 130 and the conical hole 133 continuous with the cylindrical hole 132 have a widest diameter of 2 cm so that the cap attachment portion 220 of the eyedrops bottle 200 can be inserted. size. In addition, the portion of the conical hole 133 with a small diameter (the portion in contact with the pore 134 ) has a very small size so that it can come into contact with the tip of the eyedropper 230 of the bottle 200 for eyedrops.

By configuring the resin member 130 in this manner, the eyedropper opening 230 side of the eyedrop medicine bottle 200 can be fitted into the holes 132 and 133 of the resin member 130 as shown in FIG. In the example of FIG. 1, the cap attachment portion 220 of the eyedrops bottle 200 is in contact with the cylindrical hole 132, and the flexibility of the resin member 130 itself enables the eyedrops bottle 200 to be tightly held.

However, as shown in FIG. 1, the cap attachment portion 220 is in contact with the cylindrical hole 132, which is an example. It may come into contact with any one of 132 and 133 points.
By arranging the resin member 130 of the present example in this manner, the resin member 130 can closely hold eyedrops bottles 200 of various sizes.

Then, as shown in FIG. 1 , the stepped portion 131 of the resin member 130 is connected to the one end portion 112 a of the pipe 112 . The pipe 112 is arranged inside the container 110 and the other end 112 b is connected to the tip of a chemical liquid suction pipe 144 extending from the injection mechanism section 140 attached to the lid 120 . In FIG. 1, the resin member 130 and the injection mechanism portion 140 are connected by bending the pipe 112 into a U shape in the middle, but the shape shown in FIG. may be placed inside the container 110 at .

The chemical liquid suction pipe 144 generates an atmospheric pressure change by pushing down the protruding member 142 . This atmospheric pressure change sucks out the liquid medicine in the eyedrop medicine bottle 200 connected to the pipe 112 through the liquid medicine suction pipe 144, and the sucked out liquid medicine is sprayed outside from the nozzle 143 in the form of a mist.
The projecting member 142 is pushed upward by the action of a spring (not shown) arranged inside. A liquid medicine (eye drops) is sprayed in the form of a mist. Although illustration is omitted, the chemical liquid suction pipe 144 is provided with a member that prevents the chemical liquid sucked into the chemical liquid suction pipe 144 from flowing back to the pipe 112 side.

The injection amount of the eye drops when the protruding member 142 is pushed down once is, for example, about 40 to 50 μml, and the maximum is about 70 μml.
It is preferable that the injection angle of the eyedrops from the nozzle 143 is narrow, but a somewhat wide angle such as 30° may be used.
Although illustration is omitted, the detailed structure in which the projection member 142 is pushed downward inside the injection mechanism portion 140 to generate an atmospheric pressure change has already been put into practical use as a spray bottle or the like. Various configurations are applicable.

FIG. 2 shows a usage example of the eye drop aid 100 of this example.
The patient U who receives the eye drops holds the eye drop aid 100 loaded with the eye drop bottle 200, directs the nozzle 143 (see FIG. 1) in front of the eye e of the patient U, and pushes the protruding member 142. Press down to mist the eye drops. Thereby, the eye drops can be appropriately administered to the patient's U eye e. 2 shows a state in which the direction of the nozzle 143 is rotated by 90° from that in FIG.

For example, by pushing down the protruding member 142 once and ejecting about 40 to 50 μml of the eye drops, about 20 μ ml of the eye drops reach the area where the eye drops are effective, such as the conjunctival sac of the eye e. administration of an appropriate amount of eye drops becomes possible.
It should be noted that even if the eye drop aid 100 of this example is not used and the eye drops are directly dripped into the eye of the patient from the normal bottle 200 for eye drops, most of the eye drop overflows from the eye. At most, about 20 µml of eye drops remain in the conjunctival sac. Therefore, it can be said that an appropriate amount is also administered by the eye drop aid 100 of this example.

As can be seen from the example of use shown in FIG. 2, in administration using the eye drop aid 100 of this example, the eye drops can be administered in a comfortable posture without the need to turn the face of the patient U upward. As a result, even elderly people and infants, for example, can administer eyedrops very easily.
In addition, since the eye drop aid 100 of this example has a very simple configuration, it can be manufactured at a relatively low cost, and can be distributed to patients together with the eye drop medicine bottle 200 at a pharmacy or the like to be disposable. Therefore, it is possible to prevent contamination by various bacteria due to repeated use. However, if sterilization or the like is possible, the eye drop aid 100 of this example may be used repeatedly.

In the above-described embodiment, as shown in FIG. 1, the tip of the eyedrops medicine bottle 200 is arranged facing downward in the eyedrops aid 100, but the eyedrops medicine bottle 200 can be sucked up. If so, the pipe 112 may be straight and shortened, and the eyedrops bottle 200 may be placed facing upward.

In addition, the resin member 130 for tightly holding the eyedrops bottle 200 is adapted to fit various shapes of the eyedrops bottle 200, but a plurality of types with different shapes of the holes 132 and 133 are prepared to make the resin member 130 more flexible. Many sizes of eye drop medication bottles 200 may be tightly held.

Also, the injection mechanism part 140 is configured to be injected by pushing down the protruding member 142, but may be of other shapes. For example, a lever may be arranged so that the fuel is ejected by pressing the lever.

Furthermore, in the usage example shown in FIG. 2, an example of administration to a human patient is shown, but the eye drop aid 100 of this example can also be used when administering eye drops to a patient other than a human.
For example, the eye drop aid 100 of this example can also be applied when eye drops are administered to the eyes of animals such as dogs and cats. In the case of animals, it is difficult to get them to assume a posture for administering conventional eye drops, so the use of the eye drop aid 100 of this example is also very effective in administration to animals.
