The PIH encloses a patient\u2019s upper torso and head in a negative-pressure environment. It provides barrier protection between a healthcare provider (HCP) and patient, and aerosol control via the negative pressure environment. The hood may also contain the spread of the virus from less critically- ill patients, reducing the need for invasive procedures.<\/span><\/p>\n\n\n\n<p><span style=\"font-weight: 300\">The versatility of the Apollo PIH means that it can be used in any care setting (OR, PACU, ICU, ED, EMS) and can be rapidly secured to a variety of beds. The lightweight (&lt;5 lbs) design allows for ease of assembly, use, and disposal. The primary structure is composed of a single flat sheet of PETG plastic that is assembled into a 3-dimensional form, minimizing the number of seams for optimal viewing clarity. Flexible sealed arm ports provide HCP access to patients. A minimal amount of folds and seams in the primary enclosure provide optimal viewing clarity.<\/span><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Precedents<\/h2>\n\n\n\n<div class=\"wp-block-columns

below:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>(2) arm ports at the rear of the PIH provide healthcare provider (HCP) access to the patient. &#8211; An additional auxiliary port on one side of the PIH allows for further patient access as needed.<\/li>\n\n\n\n<li>Minimal surface seams allow for an unobstructed view of the patient.<\/li>\n\n\n\n<li>Adaptable attachment mechanism allows for use on a variety of bed types (OR, ICU, etc.)<\/li>\n\n\n\n<li>Side arms provide a double thickness at the base of the PIH for stability and structure<\/li>\n\n\n\n<li>Various suction ports accept standard negative pressure hoses, including a \u215e\u201d diameter (typical in OR) as well as smaller 3\/16\u201d ID tubing (standard in the ICU).<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Fabrication<\/h3>\n\n\n\n<p>The fabrication of the \u2018Apollo3\u2019 hood can be subdivided into two parts:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The enclosure<\/li>\n\n\n\n<li>The functional elements<\/li>\n<\/ul>\n\n\n\n<p><a href=\"https:\/\/github.com\/MaPS-GSD\/Apollo3-PIH#bill-of-materials\">Learn more about the Bill of Materials<\/a><\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Enclosure<\/h4>\n\n\n\n<p>The primary design element of the Apollo PIH is the enclosure &#8211; a thin sheet of clear PET-G plastic in 60mil (approximately 1\/16\u201d) thickness. It can be CNC cut from a flat sheet of PET-G measuring a minimum of 48\u201d x 72\u201d. The Apollo PIH enclosure measures approximately 22\u201d in width, 23\u201d in height and 22\u201d in depth and is about 0.15 m3 in volume.<\/p>\n\n\n\n<p>The Apollo PIH requires a minimum stock size of 72\u201d x 48\u201d. The stock can be cut using several CNC processes, including a knife cutter, laser cutter, or router. In the case of a CNC router, a \u215b\u201d diameter endmill is required to cut small interior features successfully. A list of suggested cut settings is provided below. Please keep in mind that these settings are specific to the machines listed and will likely need to be modified for other scenarios.<\/p>\n\n\n\n<p>Knife Cutter (<a href=\"https:\/\/www.zund.com\/en\/cutting-systems\/digital-cutting-systems\/g3-cutter\">Zund G3M2500<\/a>)<\/p>\n\n\n\n<p>Bed Size: 98\u201d x 52\u201d.<\/p>\n\n\n\n<p>Tool: Universal Cutting Tool (UCT) with&nbsp;<a href=\"https:\/\/shop.zund.us\/en-us\/products\/alle-produkte\/cutting-accessories\/gliding-shoe\">glide shoe<\/a>)<\/p>\n\n\n\n<p>Blade: Type6 blade<\/p>\n\n\n\n<p>Depth: 0.02\u201d per pass<\/p>\n\n\n\n<p>Speed: 6\u201d per second<\/p>\n\n\n\n<p>Total Time: ~ 18 minutes.<\/p>\n\n\n\n<p>&nbsp;<\/p>\n\n\n\n<p>Laser Cutter (450 Watt Multicam Magnus 48&#215;96 CNC Laser, 4\u201d Focal Lens)<\/p>\n\n\n\n<p>Speed: 480 IPM<\/p>\n\n\n\n<p>Power 60%<\/p>\n\n\n\n<p>Frequency: 10,000 PPI<\/p>\n\n\n\n<h5 class=\"wp-block-heading\"><span style=\"font-weight: 300\">Base Plate Braking\/Bending<\/span><\/h5>\n\n\n<div class=\"wp-block-image\">\n<figure data-wp-context=\"{&quot;imageId&quot;:&quot;69e1f7fe6973e&quot;}\" data-wp-interactive=\"core\/image\" class=\"aligncenter wp-lightbox-container\"><img decoding=\"async\" data-wp-class--hide=\"state.isContentHidden\" data-wp-class--show=\"state.isContentVisible\" data-wp-init=\"callbacks.setButtonStyles\" data-wp-on-async--click=\"actions.showLightbox\" data-wp-on-async--load=\"callbacks.setButtonStyles\" data-wp-on-async-window--resize=\"callbacks.setButtonStyles\" src=\"https:\/\/research.gsd.harvard.edu\/maps\/files\/2024\/11\/3_Baseplate-1024x576-2.jpg\" alt=\"Picture of the base plate bending\" class=\"wp-image-7176\" \/><button\n\t\t\tclass=\"lightbox-trigger\"\n\t\t\ttype=\"button\"\n\t\t\taria-haspopup=\"dialog\"\n\t\t\taria-label=\"Enlarge\"\n\t\t\tdata-wp-init=\"callbacks.initTriggerButton\"\n\t\t\tdata-wp-on-async--click=\"actions.showLightbox\"\n\t\t\tdata-wp-style--right=\"state.imageButtonRight\"\n\t\t\tdata-wp-style--top=\"state.imageButtonTop\"\n\t\t>\n\t\t\t<svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"12\" height=\"12\" fill=\"none\" viewBox=\"0 0 12 12\">\n\t\t\t\t<path fill=\"#fff\" d=\"M2 0a2 2 0 0 0-2 2v2h1.5V2a.5.5 0 0 1 .5-.5h2V0H2Zm2 10.5H2a.5.5 0 0 1-.5-.5V8H0v2a2 2 0 0 0 2 2h2v-1.5ZM8 12v-1.5h2a.5.5 0 0 0 .5-.5V8H12v2a2 2 0 0 1-2 2H8Zm2-12a2 2 0 0 1 2 2v2h-1.5V2a.5.5 0 0 0-.5-.5H8V0h2Z\" \/>\n\t\t\t<\/svg>\n\t\t<\/button><\/figure><\/div>\n\n\n<p><\/p>\n\n\n\n<p>The base plate (2 offshoots located at the base of the design) is responsible for imparting stability to the hood, and also the method of connection makes it adapt to different bed sizes as it makes the hood behave as a compliant mechanism.<\/p>\n\n\n\n<p>The base plate portion of the Apollo PIH enclosure must be cold-formed to a 90-degree angle relative to the rest before assembly. To date, this has been successfully accomplished on a sheet metal finger brake, such as the Baileigh SBR-4020 shear brake roll (Link). Additional forming processes, such as the use of a line brake or heat gun or design modifications to the enclosure, such as eliminating the base plate or incorporating a secondary hinge mechanism, exist as potential alternatives.
