Description

Medicine feeder for infants

Technical Field

The utility model relates to the technical field of health care products, in particular to a medicine feeder for infants.

Background

In the period of human infants, the infants are vulnerable to diseases such as cold and wind-cold, or take preventive medicines for preventing the diseases, and the infants have weak esophagus and cannot take solid tablets orally, so that liquid medicines are required to be taken, and generally, the medicines are bitter and astringent, so that the infants have the action of resisting taking medicines, and the liquid medicines are spitted out, so that the dosage is insufficient. For this reason, various infant medicine feeders have appeared, and most medicine feeders adopt the structure of piston injection propelling movement, directly push the infant oral cavity depths with the medicament, make it ingest, sometimes in order to eliminate infant's resistant heart state, feed sweet liquid such as milk, fruit juice etc. first, pour into the liquid medicine into and make it swallow together when it swallows, can effectively reduce infant's condition of spitting medicine. However, the difficulty of feeding is increased by two times of feeding, and the bussiness is unavoidable. Several structures of applicators capable of holding two fluids are also described in the prior art, for example:

1. a medicine feeder for infants; CN85205829; a medicine feeder for infants. The medicine feeder can be used for injecting sugar, medicine mixed solution and sugar water (or boiled water) into the child mouth in sequence, and the medicine feeding can be completed rapidly without opening the child mouth. And because the medicine is fed in the way, children are not afraid and do not resist, so that the possibility of medicine scattering is thoroughly eliminated.

2. A double-cavity medicine feeder for infants; CN201220564083.3; an infant double-cavity medicine feeder belongs to the field of medical appliances. Is provided with a double cavity, and is characterized in that: two cavities are arranged in the double cavity, a push pipe is respectively arranged in the two cavities, push handles are arranged at the upper ends of the push pipes, two supporting plates are arranged on two sides of the double cavity, a liquid injection nozzle is arranged at the bottom of the double cavity, and the liquid injection nozzle is communicated with the two cavities. The utility model has simple structure and convenient operation, can smoothly feed medicines to infant patients and ensures the treatment effect of the medicines.

The infant medicine feeder is similar to the infant medicine feeder and is provided with two parallel piston cavities and two piston rods, but when the infant medicine feeder is used, the two pushing operations can be completed only by changing the positions of fingers (usually thumbs) required to be pushed in the pushing process, if the actions are not skilled and the dwell time is too long in the process, the infants can already swallow sweet liquid to complete, after the liquid medicine is fed again, the infants can already react, or the liquid medicine can be discharged, so that the feeding process of the liquid medicine is not smooth.

Disclosure of Invention

The utility model aims to provide a medicine feeder for infants, which adopts a coaxial double-piston structure, so that a user can realize sequential pushing and injection of two liquids without switching finger pushing actions in one pushing action, and the injection operation can not be stopped, and the feeding effect is better.

In order to achieve the above purpose, the technical scheme of the utility model is as follows:

the piston cylinder is provided with two layers of cavities, comprising a core piston cavity and an annular piston cavity, and a core piston rod and a core piston head are arranged corresponding to the core piston cavity; an annular piston rod and an annular piston head are arranged corresponding to the annular piston cavity, and the upper end plate of the core piston rod is larger than the through hole of the annular piston rod; the lower end of the piston cylinder is fixed with a medicine feeding nozzle, the liquid outlet hole of the core piston cavity and the liquid outlet hole of the annular piston cavity are communicated with the inner cavity of the medicine feeding nozzle, and the tail end of the medicine feeding nozzle is provided with a plurality of medicine feeding holes.

The core piston rod and the annular piston rod can be respectively and simultaneously arranged up and down without mutual interference. Before use, the sweet liquid is sucked into the core piston cavity in advance, then the liquid medicine is sucked into the annular piston cavity, the top of the core piston rod is higher than the top of the annular piston rod, and the silica gel medicine feeding nozzle is sleeved into the bottom of the piston cavity; then the medicine feeding mouth is plugged into the mouth of the infant, in the first half process, the core piston rod is pushed, sweet liquid is fed in, and the infant sucks and swallows smoothly; in the latter half process, when the top of the core piston rod is level with the annular piston rod, the liquid medicine starts to be fed in, and is fed in together with sweet liquid, and as the infant does not react rapidly, the mixed liquid of the liquid medicine and the sweet liquid is swallowed, and then medicine feeding is completed smoothly.

And a pull ring is arranged at the upper end of the core piston rod. The pull ring is used for conveniently pulling up the core piston rod upwards, and can also prevent the finger from slipping off the piston rod in the pushing process.

The medicine feeding mouth is in a duckbill shape and is made of silica gel. The duckbill-shaped medicine feeding mouth can be more fit with the oral shape of an infant, so that the infant can easily suck and swallow. The medicine feeding mouth is spliced with the connecting part of the piston cylinder, and the elastic splicing of the silica gel medicine feeding mouth is utilized to facilitate the disassembly and cleaning of the medicine feeding mouth.

The annular piston cavity has a plurality of liquid outlet holes uniformly distributed at the bottom of the annular piston cavity. The volume ratio of the annular piston cavity to the core piston cavity is 4:1-5:1, a small amount of sweet liquid is injected in the early stage to induce the infants to swallow, and the liquid medicine is injected in the later stage as the main dosage.

The utility model has the advantages that:

1. the utility model adopts a coaxial double-piston structure, so that a user can realize the sequential pushing injection of two liquids without converting finger pushing actions in one pushing action, the stop of injection operation can not occur, and the feeding effect is better.

2. The utility model is convenient to clean, the core piston rod, the annular piston rod and the medicine feeding nozzle can be disassembled for respectively disassembling and cleaning, and the use and maintenance are convenient.
