Suquo Systems Surgical Mask Ear Bypass This is a very simple but useful part that can help hold your surgical mask tighter to your face. It helps eliminate the obvious gap that most people have on the sides of their face when wearing a surgical mask. Link: https://grabcad.com/library/suquo-systems-surgical-mask-ear-bypass-1

       Rowan University engineering and clinical college students have evolved a prototype for a durable, lightweight, reusable face masks to reinforce the deliver of face masks at some stage in the modern scarcity of PPE all through the COVID-19 outbreak. Developed in collaboration with clinical professionals, the mask prototype might also serve in medical and discipline use. If printed, used, and maintained correctly, the mask provides a durable, reusable mechanical barrier. Ease of installation and use     The prototype offers components: a contoured mask and filter housing. No special tools are needed for assembly. The replaceable nonwoven clear out materials endorsed for the filter out housing are extensively available. The masks may be printed in three sizes, all with the equal size clear out housing. The contoured mask can be more intently molded to the user’s face by using submerging the rims in hot water and pressing it to reform the form in opposition to the

Patient Isolation Stretcher Cover PPE to be used while transporting the patient with infectious disease in ambulance or within hospital. The plastic cover can be made with transparent TPU or 16 gauge clear vinyl material and the rods from 1/2 inch ABS pipes. The overall dimensions are kept as 2mx0.6mx0.6m. Plastic zippers to be attached on the sides of the fattened plastic. 8 4" wide glove ports are provided for attaching nitrile gloves on the sides. For air circulation - At the inlet, use 2 HEPA filters 0.3micrometer, 99.99% or more. At the outlet, use HEPA filter along with filters for biological substances. In the Exhaust box, use one way valve and exhaust fan. Usually a 5CFM exhaust fan will provide a ventialtion of 12 times per hour for this volume of containment. A 12 Volt battery is used to power the exhaust unit. A pouch can be attached to the canopy, for holding the battery link: https://grabcad.com/library/patient-isolation-stretcher-cover-1

Baxter Ventilator Aim: The Baxter Ventilator was designed especially to find a solution a shortage of ventilators during a pandemic. How do Baxter Ventilator work? The ventilator provides volume control continuous mandatory ventilation (VC-CMV). The tidal volume, respiratory rate, inspiratory to expiratory time (I/E), positive end expiratory pressure (PEEP), and fraction of inspired oxygen (FiO2) can all be set on a touch screen or through manual controls. For the patient's safety, the maximum Peak Inspiratory Pressure (PIP) will not exceed 40 cm of water. To allow for use in field hospitals, the ventilator can use ambient air, high or low pressure oxygen. Findings: the prototype metts the appropriate criteria and produced results similar to industry-standard ventilators when testing on a Gaumard HAL S3201 simulator.

What is a ventilator and what does it do? Simply put, a ventilator takes over the body's breathing process when a disease has caused the lungs to fail. This gives the patient time to fight off the infection and recover. Various types of medical ventilation can be used. According to the World Health Organization (WHO), some 80% of people with Covid-19 - the disease caused by coronavirus - recover without needing hospital treatment. But one person in six becomes seriously ill. In these severe cases, the virus causes damage to the lungs, causing the body's oxygen levels to drop and making it harder to breathe. To alleviate this, a ventilator is used to push air, with increased levels of oxygen, into the lungs. The ventilator also has a humidifier, which adds heat and moisture to the air supply so it matches the patient's body temperature. Patients are given medication to relax the respiratory muscles so their breathing can be fully regulated by the machine.

VentilAid is a very simple, yet effective device for non-invasive ventilation. It is especially projected to help patients suffering from COVID-19. VentilAid helps breathing, prevents alveoli from collapsing and monitors patients health. Major features Compactness and mobility Universal power supply Automatic function in CPAP and BiPAP modes FiO2 do 70%, Up to 70% FiO2 Pressure up to 15 cm H2O (wi th a greater technical capablity of up to 30cm H2O) The device adapts to the breathing rhythm of the patient https://www.ventilaid.org/ventilaid-breathing-device-mk-iii/
