BRIEF SUMMARY
FIELD OF THE INVENTION
Background of the Invention
This invention relates to a device for orally administering a liquid to humans.
Oral administration of liquids especially to children can be extremely difficult at times, such as when a measured amount of a medicine is to be given. The usual method is simply to use a spoon. The spoon may be specific to a certain measure or just an ordinary household spoon, but if the child does not want to accept the medicine it is extremely difficult to coax it to take the medicine without some loss. Alternatively too much medicine may be administered if more is given to compensate for that lost in the previous attempt. This effect is heightened considerably if the medicine is distasteful.
Alternatively a dropper can be used for oral administration. Such a device comprises a bulb head, usually made of rubber and is attached to one end of a tube. The other end of the tube has an opening through which liquid can enter. Liquid is drawn into the tube if, pressure is first applied to the bulb, the open end of the tube is placed in a liquid and the pressure then released. This device therefore provides some measure of directional control as the liquid can only leave the tube by way of the opening at its end. However since continual pressure has to be administered to the bulb in order to retain the liquid within the tube only one hand is left free to correctly position the dropper in the child's mouth. Great care is also required to ensure that the correct number of drops are administered.
Oral administration devices for humans are known from GB 1454966 which dislcoses a syringe having a cylinder and piston terminating at its outlet end with a screw cap arangement for screwing to a filling bottle. The screw cap arrangement. This is unsuitable for inserting into a child's mouth because of its relative size and terminal shape. EP-A3-0295143 shows another oral dosing syringe. Whilst this has a more friendly terminal shape it has little to prevent it being pushed too far into a child's mouth. Aural syringes, that is syringes for washing out ears, have been provided with discs at the terminal ends but these syringes are unsuitable for dosing because they do not have a plunger arrangement but merely a bulb.
SUMMARY OF THE INVENTION
A device for orally administering a liquid according to the present invention comprises a manually operable plunger slidably mounted within a container having an oral dispensing outlet, the plunger being operable to administer the liquid through the outlet, wherein the outlet is at least partly surrounded by a radially extending shield.
The radially extending shield prevents the outlet from being inserted too far into a child's mouth and has an additional advantage that it can act as a seal with a bottle top when refilling the device. In a preferred embodiment a resilient sealing disc can be placed over the outlet to abut between the shield and the bottle top.
Preferably the shield is curved backwards toward the distal end of the device. This has the advantage that it is kinder on the child's mouth and it also ensures that when locating on a bottle top during replenishing the contact with the top is better.
In one embodiment the shield also acts as handles suitably positioned near the outlet of the container, however in a preferred embodiment the shield is either formed as a uniform circular extension from the device at the outlet end or else the shield is formed with an oblong shape that is mainly extending in a single diametrical direction either side of the axis of the device.
The advantage of the circular shape is that which ever way the device is picked up it is symetrical for the use and it fits against the rim of a large open topped vessel during filling or replenishing. The advantage of the oblong shape is that when suitably positioned in a child's mouth it does not abut the child's nose. Of course the shield's shape can be circular with a cutaway nose avoiding sector.
The shield may be formed as a separate part the outlet member when this is
