Abstract

A drug-feeder for children comprises a drug chamber and a drug guider. A rotating member is disposed at a front end of the drug guider and can be rotarily adjusted to optionally inject the liquid drug in the drug chamber in an upward direction or two lateral directions to cure different areas in the oral cavity of the child. The drug chamber and the drug guider are inclinedly connected to form an angle about 130 degrees between them so that when the drug-feeder is Placed in the mouth of the child, the oral cavity of the child can still be clearly seen and no drug will drop onto the tongue of the child before the drug guider reaches the desired position for treatment, preventing the child from resisting against the drug feeding due to the bad taste of drug.

Claims

1. A drug-feeder for children, comprising:

a long and flat tube-like drug guider having a substantially elliptical cross section, said drug guider having a front end Portion which is formed with two horizontal injecting orifices and a recess, a flow passage formed inside said drug guider, an arcuate stopper being integrally formed under a rear end of said drug guider for abutting against the lower lip and chin of a child using said drug-feeder, and a downward inclinedly extended coupling portion formed behind said arcuate stopper and forming an angle about 130 degrees between said coupling portion and said drug guider;

a rotating member rotatably disposed in said recess of said drug guider having a top adjusting recess, an upward inclined tunnel, and a Y-shaped tunnel;

said upward inclined tunnel having an upper injecting orifice, and said Y-shaped tunnel being communicable with said two horizontal injecting orifices formed on said drug guider; and

a drug chamber made of transparent silicone resin or rubber with marked scales thereon for accurate dispensing of drug having a guide tube disposed therein to communicate with said flow passage of said drug guider and being detachably connected to said drug guider via said downward inclindedly extended coupling Portion of said drug guider, such that the areas needing cure in the oral cavity of a child can be clearly seen even when said drug-feeder is placed in the mouth of the child, and that no liquid drug in said drug chamber will drop onto the tongue of the child before said drug guider reaches the areas needing cure, causing the child to taste the drug and thus resists the drug feeding.

2. A drug-feeder as claimed in claim 1, wherein a first and a second check valves are disposed in said coupling portion of said drug guider, said first check valve permitting the air to irreversibly enter said drug chamber while said second check valve permitting the liquid drug to irreversibly flow outward from said drug chamber through said guide tube to said flow Passage of said drug guider and finally to the oral cavity of the child.

3. A drug-feeder as claimed in claim 1, wherein said adjusting recess has an opening end formed at an outer periphery of said rotating member such that when said opening of said adjusting recess is turned to point a front end of said drug-feeder, said Y-shaped tunnel is communicable with said guide tube in said drug chamber through said flow Passage of said drug guider, permitting said liquid drug to be transferred from said drug chamber through said flow Passage of said drug guider to said Y-shaped tunnel and then injected outward from said two horizontal injecting orifices on said front end portion of said drug guider, while when said opening of said adjusting recess is turned to Point backward, said upward inclined tunnel is communicable with said flow passage so that said liquid drug is transferred through said flow passage to said upward inclined tunnel and then injected outward from said upper injecting orifice thereof.
