Built from wood, a square frame supports a wooden base. On the right hand side of the support are two bolts, one in each corner.
At the front of the base is a horizontal length of wood which has been attached on the long edge with PVC glue and nails. On this piece is the text "PEAR-1" hand-drawn in black vivid on yellow card which has been stuck to the board with a transparent sticker. On either side of this label are two symbols. On the left is the St John's College, Hastings, school logo attached with Bluetack. On the right is a green pear with the text, "PEAR" printed in white in the middle, also attached with bluetack.
Along the bottom of the base is a long plank of wood, spray painted silver.
In the centre of the base is a yellow Ambu bag, attached to the base with twine at each end. At the top of the bag is a clear plastic valve connecting to a single air cushion mask. Embossed on the air cushion mask is the text, "CE / #5 ADULT / 2". On the base on the mask is the text, "SINGLE PATIENT USE / CE". At the top of the mask is the text, "cmH2O" embossed in white. At the bottom of the Ambu bag is a clear plastic valve connecting to a vinyl oxygen reservoir bag and a transparent, green oxygen tube. The tube is held in a coil with a pink rubber band. Printed around the opening of the oxygen reservoir bag is a white sticker with a motif of the number 2 crossed out, repeated across the sticker. At the bottom of the Ambu bag is a plastic connector in which a long piece of white fabric is attached, containing velcro at one end.
Protruding from the top centre of the base is a piece of wood with another, longer and thinner piece of wood attached on top of this. This forms the base of the mechanism which runs the ventilator. At the top of the long piece of wood is another layer of thin wood shaped in a square. This has a series of holes which run vertically. A long piece of grey lego is inserted into this hole. This in turn is connected to a horizontal orange piece of lego. Another vertical grey piece of lego runs through this and connects to a piece of wood. This piece of wood is connected to the main block of wood with another piece of lego which is then pushed into the Ambu bag when running. These two pieces of wood are spray painted silver. The main pushing block is sheltered in a wooden enclosure, constructed from three square pieces of wood, nails, white plastic coating and PVC glue.
The PEAR-1 ventilator is an example of New Zealand innovation that showcases the use of easily sourced materials to develop an affordable solution to a problem. Project Pear’s use of contemporary communication technology, specifically Zoom, talks to the significant upsurge of such communication technologies and the connectivity and innovation they allowed during New Zealand's Level 4 lockdown.
