This International Application claims priority from a complete patent application filed in India having Patent Application No. 201941015064, filed on April 15, 2019 and titled“DENTAL RECLINER CHAIR WITH ARM REST”

FIELD OF INVENTION

Embodiments of a present disclosure relates to a special purpose chair, and more particularly to a portable dental recliner chair.

BACKGROUND

A dental recliner chair refers to a particular chair used by a dentist or a dental hygienist at a dental clinic. A standard dental recliner chair in a clinic has 4 distinct components a) A large dental recliner chair with a pneumatically controlled recliner system, b) dental recliner chair compressor unit which provides pneumatic power for the recliner and air pressure for the dentists hand pieces that are used for treatment, c) an integrated work table with pneumatic pipes attached to dental hand pieces and d) a small faucet and a spit-sink, which the patient may use for rinsing, as well as one or more suction hoses, and a compressed air/irrigation water nozzle for blowing or washing debris clear of the work area in the patient's mouth. All the features are integrated together as a whole with the dental recliner chair. During check-up or operation, a patient should be able to sit on a dental recliner chair that uses a recliner mechanism to shift the patient to a 160-degrees for the dentist to examine and conduct dental treatment. Hence, the chair designed should be specific according to the needs of dentistry.

In conventional approach, a chair is permanently fixed in the dental office. The chair may be mechanically or pneumatically fixed in the dental room for usage. The size of the dental recliner chair is huge and weights about 120Kgs. So, it is impossible to move it around or carry it to any particular place.

In India and the developing countries 90% of the population do not have access to dental care. The problem is acute in smaller towns and rural villages. The time taken to visit a dentist and get back is about 2 hours. So most people tend to avoid visiting a dentist. According to World Health Organisation (WHO) a child must visit a dentist once in 6 months and an adult once a year. Hence, there is a need for an improved portable dental recliner chair with arm rest to make dental care affordable and accessible to all.
