DESCRIPTION:
BRIEF SUMMARY
This invention relates to personal protection for infants.
The invention is concerned especially with affording infants protection against air pollution when for example in a pram, baby-buggy or carry-cot.
Babies and other infants when transported in a pram, baby-buggy or carry-cot in the street are often exposed to air that is polluted with high levels of motor-vehicle exhaust fumes. The levels of pollution to which they are exposed are generally higher than those experienced by adults since the infant breathes air from a lower level, closer to the source of emission of the fumes into the atmosphere. The matter is of particular concern because an infant is physically less able even than an adult to cope with pollution and is more likely to develop respiratory disorders from exposure to exhaust fumes.
Equipment for affording an infant protection against ambient-air pollution in a pram is known from DE-A-4241233 and involves a portable unit containing an air-filter and a motorised fan, that attaches to the side of the pram. The hood of the pram is raised and a transparent sheet is used to close off the inside of the pram from the ambient atmosphere. Filtered air supplied from the unit is blown into the interior of the pram through the sheet near the top of the hood, via a hose connection. Although air outlets are provided in the sheet for ventilation, they are located where the sheet covers the opening to the hood and not spaced significantly in relation to the infant from where the air enters through the hose-connection. There is accordingly the problem of the likelihood of air stagnation within the pram, and the consequent danger that the filtered air will not reach the infant; this problem is increased by the high location of the hose-connection in the hood.
It is an object of the present invention to provide equipment for affording an infant protection against ambient-air pollution, that reduces to a significant extent the likelihood of air stagnation.
According to the present invention there is provided equipment for affording an infant protection against ambient-air pollution, in which a compartment for enclosing the infant involves an elongate base-support which is of a configuration to support the infant in an appropriate sitting or other posture within the compartment, and a canopy that is transparent throughout at least a substantial part thereof, for extension over the infant on the base-support to close-up the compartment except for at least one or more openings at which the compartment is vented freely to the ambient atmosphere, and in which the equipment also includes motorised means carried with the base-support for blowing filtered ambient-air into the compartment at a location spaced from said one or more openings to create positive pressure in the compartment relative to the ambient air-pressure, the equipment being characterised in that the motorised means is located at one end of the base-support for blowing the filtered air into the compartment to flow towards the other end lengthwise of the infant on the base-support, and that said one or more openings are located towards or at said other end of the base-support.
The canopy may extend fully over the base-support, and may comprise flexible transparent sheeting supported on arched stays that are pivotable for selective extension of the canopy over the base-support. An element of mesh may be inset into the canopy for venting air from the compartment and avoiding build up of heat within the compartment.
The base-support, which may be mounted on a wheeled chassis, may be of an elongate dished configuration and may be suspended within an open frame element that carries the canopy. More particularly, it may include a substantially-rigid panel that is suspended on fabric sections which define walls of the base-support; one of the sections may provide a seat for the infant, with the panel as backrest.
For seating the infant, the base-support may be mounted to have an inclined attitude, and in these circumstances the means for blowing the filter
