The present subject matter relates generally to a medical isolation device that isolates the head of a patient and the surrounding air from the ambient environment within a room. More specifically, the present subject matter provides a medical isolation device including a draped body that is placed over the patient's head while lying on a table.
The COVID-19 pandemic has flooded emergency rooms and intensive care units across the world with patients suffering from the virus, and this is simply one example infectious disease. As infectious diseases are transmitted between people in close proximity through physical contact and/or airborne droplets, treating patients infected with COVID-19 is proving to be exceptionally difficult. Respiratory distress is a common complication often requiring intubation. In a typical emergency environment, such as a patient being brought into an emergency room via ambulance with the patient exhibiting severe and acute symptoms of COVID-19, medical professionals are left with few options to protect themselves and support staff. The medical staff is exposed to contaminated air or contagions expelled from the patient into the room, and are at risk of direct transmission via contact with contagions and/or airborne droplets of known and unknown illnesses. At the same time, patients are exposed to potentially contaminated air from other patients or carriers.
In addition to emergency rooms, a multitude of environments pose serious risks to medical professionals and those taking care of infected persons: the operating room for induction and emergence of anesthesia and throughout surgical procedures, intensive care units (ICUs), endoscopy suites, radiology suites, magnetic resonance imaging (MRI) procedures, ear, nose, and throat (ENT) procedures, emergency medical technician (EMT) and paramedic vehicles, dental offices, patient transportation, hospice, and any other situation or location where medical care is provided. Further, medical and non-medical persons are even more limited in protection when caring for loved ones or others at home during end of life care.
Medical professionals wear standard personal protective equipment (PPE) while working in these environments to prevent the transmission of the infection. PPE, however, is not 100% effective in blocking transmission. Further, medical professionals also have difficulty donning and doffing personal protective equipment. For example, the excess time spent for each person in an emergent situation to don personal protective equipment and address time sensitive ailments of a patient may cause a failure to timely treat an acute issue or force medical professionals to make choices about their own safety.
Accordingly, a need exists for a medical isolation device to isolate an infected patient and the patient's airflow from the surrounding environment, and/or isolate a non-infected patient and the patient's airflow from surrounding contaminated air during a high volume turnover in emergency rooms during a pandemic. There exists a need for a medical isolation device that the medical professionals and patients have discreet respiratory environments from each other, as described herein.
To meet the needs described above, the present application provides a medical isolation device to isolate a patient and the patient's airflow, such that the medical professionals and patients have discreet respiratory and physical environments from each other.
In an embodiment, the medical isolation device includes a body and a drape extending from the body to create an enclosed space. The body includes at least one porthole and a porthole cover within the porthole to enable the medical personnel to access the patent within the body. An oxygen port and a suction port on the body provide passageways through the body to enable air circulation for the patient without exposing medical personnel to the infected air.
The body includes a first side portion, a second side portion, a top portion, and a back portion. A front side edge is formed along a first edge of the first side portion, a first edge of the second side portion, and an edge of the top side portion. A base edge is formed along a second edge of the first side portion, a second edge of the second side portion, and an edge of the back side portion. The drape is attached to the front side edge of the body and extends at least the full height and width of the front side opening.
One or more portholes provide a throughway in the body through which medical devices such as but not limited to intubation equipment, hands, arms, and other items can be placed. The portholes include a porthole cover that fits securely into the porthole and limits the exchange of air in and out of the body of the medical isolation device. The porthole cover includes an outer edge that mates with a porthole edge of the porthole and an inner edge spaced from the outer edge defining the throughway. The porthole cover is removable from the porthole for immediate access to the patient in an emergency situation as well as for cleaning purposes.
The porthole cover is biased into a folded position such that the inner edge comes together to close the throughway. Upon the application of force to the porthole cover, the cover unfolds such that the inner edge is drawn apart to open the throughway. The porthole cover is comprised of a material that is flexible in order to unfold upon the application of force but sufficiently rigid to be biased into a folded position and withstand negative pressure within the medical isolation device. One example material is silicone, although other suitable materials may be used.
In some embodiments, the front side edge of the body is flanged. The drape may include a plurality of pegs along an attachment edge, and a flange on the front side edge of the body may include a plurality of holes for mating with the plurality of pegs of the drape. The attachment edge may attach to the front side edge of the body through a hook and loop attachment. In yet another embodiment, the drape has a grooved attachment edge for receiving the flanged front side edge of the body.
In another embodiment, the edge of the porthole is flanged. In yet another embodiment, the outer edge of the porthole cover is grooved for receiving the flanged edge of the porthole.
During use, the combination of the body and the drape, and the ports creates an enclosure that is capable of withstanding negative pressure.
An object of the medical isolation device is isolate air expelled by an infected patient and the ambient environment of the medical professionals treating the patient, or to isolate the air flow of a healthy or immunocompromised patient and an ambient environment at risk of carrying contagions.
A further object of the medical isolation device is to allow access to the patient for procedures, such as intubation, while isolating the respective ambient environments of the patient and medical professionals.
An advantage of the medical isolation device is that medical professionals are not exposed to physical and/or airborne pathogens, such as COVID-19, while treating patients.
A further advantage is the ability to easily sterilize and autoclave the medical isolation device for constant reuse. During a pandemic, the ability to sterilize and autoclave for easy reuse is valuable as supply chain shortages can be anticipated.
Another advantage of the medical isolation device is that patients have improved portability throughout a care facility, such as a hospital, while preventing all encountered persons in the vicinity from breathing any air expelled by the ill patient. Similarly, the medical isolation device improves the containment of pathogens as its use in enclosed spaces such as elevators, hallways, or intermediate rooms in the healthcare facility provides a cleaner environment for all personnel, patients, and visitors.
Additional objects, advantages, and novel features of the examples will be set forth in part in the description which follows, and in part will become apparent to those skilled in the art upon examination of the following description and the accompanying drawings or may be learned by production or operation of the examples. The objects and advantages of the concepts may be realized and attained by means of the methodologies, instrumentalities and combinations particularly pointed out in the appended claims.
The drawing figures depict one implementation in accord with the present concept, by way of example only, not by way of limitations. In the figures, like reference numerals refer to the same or similar elements.

Referring to
The porthole cover 114 includes an outer edge 140 that mates with a porthole edge 113 of the porthole 112 in the body 108, as shown in
When no force is applied to the porthole cover 114, the cover 114 is biased toward a folded position such that the inner edge 142 comes together to close the throughway 138 as shown in
As shown in
On a front side of the porthole cover 114, the planar portions 144 of the cover are separated by voids 151 formed by the folded portions 146. More specifically, the fold sides 147 of each folded portion 146 extend away from the planar portions 144, forming narrow cavities 151 between adjacent fold sides 147. During use, the object moving through the porthole cover 114 first contacts the central point 153 of the porthole cover 114. The porthole cover 114 is reversible in that it can also be positioned within the porthole 112 such that the folded portion 146 extends outwardly into the ambient environment instead of inwardly toward the interior of the body 108, as shown in the illustrated embodiment. For example, medical staff may position the cover 114 with the folded portion 146 outside of the body 108 if the respective porthole 112 is used only for moving medical instruments or tubing out of the body 108.
When the porthole cover 114 is in the folded position without force being applied thereto as seen in
The size, shape, number, and location of the portholes 112 may vary as desired. The porthole(s) 112 may vary in size according to the instruments or hands and arms of the medical personnel needing to access the patient 104 positioned within the medical isolation device 100. In the illustrated embodiment, the portholes 112 and porthole covers 114 are circular. The shape of the porthole 112 and corresponding porthole cover 114 may be square, rectangular, semicircular, or any other shape as desired. Numerous known sizes and shapes may be used, as will be recognized by those skilled in the art.

Numerous known materials may be used, as will be recognized by those skilled in the art. The oxygen and suction ports 116, 118 may be color coded or otherwise labeled for easy identification. Additional accessories, such as pressure indicators, a negative-pressure indicator, a negative pressure device, etc., may also be used with the device 100.
The oxygen port 116 and suction port 118 allow for the creation of negative air pressure within the medical isolation device 100. The pressure differential between the oxygen flow rate and the suction flow rate creates the negative pressure inside the medical isolation device 100, with the suction flow rate exceeding the oxygen flow rate. The oxygen port 116 and suction port 118 can vary in size and function depending on the need of the medical professionals 102 at the time of treatment. The medical isolation device 100 does not require an airtight seal along its edges, but is sufficiently enclosed and comprised of rigid materials to withstand a negative pressure environment within the device 100.
