Abstract
An isolation apparatus for a patient having a highly contagious disease. The apparatus includes a frame that is connected to part of a support body on which the patient is located. The frame has two flexible rods which are sized and shaped for location away from the patient. The rods can have length modifiers located at one end. This allows a user to extend and contract the rod along a path of travel so as to modify the distance between the frame and the patient. A
barrier sheet is connected to the frame and defines a comfortable living volume which is of a size sufficient to enclose the patient and the support body. To allow a caregiver access to the patient, the barrier sheet has a patient access portion.

TECHNICAL FIELD
[0001] The present relates to patient isolation enclosures, and more particularly to isolation enclosures to isolate a patient having a highly contagious disease such as that caused by viral, fungal, bacterial or protozoal infections.
BACKGROUND
[0002] When a human patient contracts a highly contagious disease caused by microorganisms, such as viruses, fungi, bacteria or protozoans, isolating the infected patient from healthy people is an effective way to significantly reduce or to prevent spread of the disease.
This is particularly important when the patient is housed in a hospital environment. The risk of disease transmission to caregivers, such as doctors and nurses, and other patients, is high.
Furthermore, the risk of disease transmission increases when family members, who may be exposed to the patient during the infectious phase of the disease, leave the immediate area near the patient and travel elsewhere. Also, first responders such as paramedics, who may be called to a person's home when they are initially taken ill and need transportation to a hospital, are at high risk of catching the disease. Moreover, further transmission of the disease to others by contact with contaminated clothing is a significant problem.

SPECIFICATION
bacteria particles such as when the patient coughs or sneezes.
In some cases, infectious agents can spread to healthy people if they contact bodily fluids such as blood, sweat, urine or fecal matter.
[0004] It is well known that an effective way to isolate an infected patient is to place a physical barrier between the patient and the caregiver. However, even if the patient is isolated behind the barrier, the virus or bacteria may still be present in the area on or around the patient, which puts at risk caregivers if they need to take blood samples or carry out routine nursing duties.
[0005] A number of groups have noted the need to isolate patients and have designed a number of isolation units which provide a physical barrier between the patient and the caregiver. Several examples of these are shown below:
[0006] Published United States patent application number US20020087045 for "Transparent disposable cover for patient transport";
[0007] Published United States patent application number US20030116566 for "Collapsible restraining enclosure for a bed";

[00013] Published United States patent application number US20060247487 for "Apparatus and method for providing continuous access to an isolation space while maintaining isolation";
[00014] Published United States patent application number US20080041399 for "Sterile Enclosures"; and [00015] Published United States patent application number US20170273844 for "Patient Isolation Tent".
[00016] While many of the above-noted designs protect caregivers from catching the disease, the care of the patient during isolation appears to be overlooked, especially if the patient is to be in isolation for an extended period.
Disadvantageously, the examples given above do not allow for expansion of the isolation tent so that they can be used with hospital beds of different sizes. Most, if not all of the tents shown above are a "one size fits all" design and do not allow for expansion and contraction of the tent, and thus do not provide comfort for the patient. For patients in prolonged isolation, this can cause feelings of claustrophobia, which may lead to mental health problems. Furthermore, the designs shown above do not effectively provide an inexpensive means by which the caregiver can quickly access the patient. While the use of separate patient contact areas are available, they appear to be overly complex. In most cases, a separate part Date Recue/Date Received 2020-08-07 Docket #: 178-P01.CA
SPECIFICATION
of the isolation tent is designed so that the hands and arms enter, albeit covered, the isolated space occupied by the patient. The patient access areas include materials that are complimentary to the size and shape of the caregivers' hands and arms, but of course this increases the complexity and therefore the cost of manufacturing. Finally, since patients have different sizes and shapes, there is a need for a bespoke isolation tent design which can be modified according to the needs of the patient.
[00017] Thus, there is clearly an unmet need for an improved patient isolation system that not only provides a safe barrier through which caregivers can administer care to the infected patient, but also provides a living volume that improves the experience during a prolonged hospital stay BRIEF SUMMARY
[00018] We have designed a modular isolation enclosure (also called an "isolation tent") for use primarily in hospital environments that significantly reduces, or essentially eliminates, the problems of "patient-to-caregiver" transfer of highly contagious diseases such as those caused by viral, fungal, protozoal, or bacterial infections, which spread either by direct patient contact or via aerosolization of mucosal droplets. Our enclosure provides a very simple, yet effective and reliable way to protect caregivers against airborne infectious disease spread. Our invention provides a novel and unobvious flexible and expandable frame system, which allows rapid expansion and contraction to accommodate patients or beds of various sizes. Unlike conventional static isolation tents, our enclosure addresses the problem of patient access and patient claustrophobia, by allowing the Date Recue/Date Received 2020-08-07 Docket #: 178-P01.CA
SPECIFICATION
caregiver to quickly and easily slide the barrier sheet up over the flexible rod system and then quickly resealing the enclosure using a variety of closing means. In one example the flexible rod system can create a patient-friendly arcuate configuration with significant volume above the patient's body. Moreover, the robust barrier provides improved patient visibility and a significant reduction in patient claustrophobia.
The enclosure provides a universal fit on hospital bed frames via multiple sleeves and/or available adaptor boots for intravenous (IV) poles and/or via altogether flexible frame members or member components. Our design uses clips, bungees, strings, adhesive tape fastener compatible to provide an aerosol (virus) hermetic enclosure so that the patient is enclosed in a sealed environment.
[00019] Since the enclosure is connected directly to the bed, it provides a stable structure, which will not slip-off the mattress and compromise the seal, unlike conventional isolation tents, some of which merely rest on the bed and can move about or even slide off the bed thereby compromising the seal around the patient.
[00020] Another advantage our enclosure has over conventional enclosures is that it can be shipped from a storage warehouse to point of delivery in a very compact, pre-loaded manner. A
unique design of articulated structure (hinges) and/or inserted telescoping posts structure aid the compact storage and transportation.
Upon arrival at the destination, the enclosure can be quickly and safely deployed by two people in less than 30 seconds. Finally, after use, the enclosure can be destroyed by incineration or transported to a landfill site after de-contamination because the materials used in Date Recue/Date Received 2020-08-07 Docket #: 178-P01.CA
SPECIFICATION
construction are low weight, low volume materials and low cost.
Furthermore, a key advantage that our new isolation housing provides is the ability to minimize the height and width of the bed if or when a patient needs to be transported between rooms in the hospital, such as for X-rays and the like which may be located remote from the intensive care unit. Our isolation housing allows for rapid lowering or narrowing of the frame to move through doors or into/out of elevators.
[00021] For extended stay patients, the enclosure can be modified to permit use of a backrest enclosure.
Pull-out end flap allows the enclosure to be further extended to maintain upper body coverage when the bed is adjusted to allow the patient to sit up, while still maintaining a seal therearound.
[00022] Desirably, the enclosure can incorporate existing fan and filter breathing systems via available fasteners and/or adaptor plates and printed cutout templates. This embodiment allows for ambient air to circulate within the enclosure should the patient's condition require such.
[00023] Accordingly, in one embodiment there is provided an apparatus for isolating a patient, the apparatus comprising:
[00024] a frame connected to a first portion of a support body on which the patient is located, the frame having first and second spaced apart rod members sized and shaped for location away from the patient; and [00025] a barrier sheet connected to the frame to define a living volume of a size sufficient to substantially enclose the patient therein, the barrier sheet having a patient access portion to permit a caregiver access to the patient Date Recue/Date Received 2020-08-07 Docket #: 178-P01.CA
SPECIFICATION
[00026] In one example, each of the rod members includes a rod length modifier located at one end thereof to permit the rod member to extend and contract along a path of travel so as to modify the distance between the frame and the patient. The first and second spaced apart rod members includes first and second spaced apart flexible rods, each rod flexible rod having: i) first and second rod length modifiers located at first and second rod ends; and ii)a passageway extending between the first and second rod ends to slidably receive therein the rod length modifiers. The first and second rod length modifiers include a telescoping member slidably mounted in the passageway, the telescoping member being mounted in the passageway using an interference fit so that the telescoping member moves along a restricted path of travel. The first and second rod length modifiers include at least one lock to lock the flexible rod when a desired rod length is achieved. Each of the flexible rods includes a connecting end for connecting the flexible rod to the support body. The connecting end is connected to an intravenous (IV) pole receiver using an interference fit.
[00027] In another example, each of the flexible rods includes a connecting end for connecting the flexible rod to a support body frame.
[00028] In another example, the first and second flexible rods each include at least one first hinge to permit a lower portion of each flexible rod to hinegably move away from the patient. The at least one hinge permits movement of the lower portion of the flexible rod from an upstanding configuration to a orthogonally disposed configuration.
Date Recue/Date Received 2020-08-07 Docket #: 178-P01.CA
SPECIFICATION
[00029] In yet another example, the first and second spaced apart flexible rods are moveable relative to each other along a longitudinal path so as to accommodate support bodies having different lengths. Each flexible rod is made from a material that is sufficiently flexible to permit forming of the rod into a desired shape to accommodate the barrier sheet and the support body.
[00OO] In yet another example, the first and second flexible rods are arcuate.
[00031] In still another example, the support body is a hospital bed. The hospital bed includes a hospital bed frame, the frame being connected thereinto. The frame is mounted on the floor around the hospital bed.
The support body is a wheeled hospital gurney. The support body is an ambulance stretcher.
[00032] In one example, the barrier sheet is shaped for location over the first and second flexible rods, the barrier sheet being secured to the rod members using one or more sheet connectors. The sheet connectors are clip members located along the length of each rod member to permit a caregiver to sealingly connect the barrier sheet to the flexible rods. The clip members extend around the perimeter of the support body to secure the barrier sheet to the support body. The barrier sheet includes first and second spaced apart sleeves into which the first and second flexible rods are slidably mounted.
The barrier sheet includes first and second spaced apart adhesive strips against which the first and second flexible rods adhere. The barrier sheet is transparent.
Date Recue/Date Received 2020-08-07 Docket #: 178-P01.CA
SPECIFICATION
[00033] In another example, the barrier sheet includes an inner surface disposed towards the patient, and an exterior side surface disposed outwardly towards the caregiver. The barrier sheet is coated substantially across the entire surface area with an antimicrobial material.
[00034] In another example, the barrier sheet includes a main barrier sheet and an upper body enclosure sheet portion configured to accommodate the patient's upper body when the patient is permitted to sit up, the upper body enclosure sheet being located rearwardly of a moveable upper body portion of the support body.
[00035] In another example, the upper body enclosure sheet portion being of sufficient volume to permit the patient's head and upper body to move between a prone position and an upright position.
[00036] In another example, the barrier sheet drapes substantially over the four sides of the support body and contacts the ground so as to completely enclose the patient and the support body.
[00037] In yet another example, the patient access portion includes a barrier sheet panel that is contiguous with the barrier sheet, the barrier sheet panel having two opposing sides temporarily sealed to the barrier sheet, the barrier sheet panel being slidable along the along the flexible rods to provide a temporary opening of sufficient size to allow the caregiver access to the patient, and thereafter to re-seal the temporary opening.
Date Recue/Date Received 2020-08-07 Docket #: 178-P01.CA
SPECIFICATION
[00038] In yet another example, the at least one second hinge located between the sleeves to allow collapse of the barrier sheet and the frame for transportation.
[00039] In one example, an air pump and fan is connected to the barrier sheet to communicate ambient air, and carbon dioxide into and out of the living volume around the patient through a filter.
[00040] In still another example, the patient has a highly contagious disease. The highly contagious disease is a viral infection or a bacterial infection. The viral infection is COVID-19.
[00041] Accordingly, in another embodiment, there is provided a method for deploying an isolation enclosure for location around a patient having a highly infectious disease, the method comprising:
[00042] locating first and second caregivers at respective first and second ends of a collapsed and substantially flattened isolation enclosure, the enclosure having first and second spaced apart flexible arcuate-shaped rods, and a barrier sheet connected to the flexible rods; and [00043] applying a pulling force to the respective first and second ends of the collapsed enclosure to fully deploy the enclosure for location around the patient so that the patient has a living volume therearound.
[00044] In one example, the method further comprises:
adjusting the flexible rod member lengths by extending or contracting the rod member lengths using rod length modifiers located at first and second rod ends so that the barrier sheet

[00016] While many of the above-noted designs protect caregivers from catching the disease, the care of the patient during isolation appears to be overlooked, especially if the patient is to be in isolation for an extended period.
Disadvantageously, the examples given above do not allow for expansion of the isolation tent so that they can be used with hospital beds of different sizes. Most, if not all of the tents shown above are a "one size fits all" design and do not allow for expansion and contraction of the tent, and thus do not provide comfort for the patient. For patients in prolonged isolation, this can cause feelings of claustrophobia, which may lead to mental health problems. Furthermore, the designs shown above do not effectively provide an inexpensive means by which the caregiver can quickly access the patient. While the use of separate patient contact areas are available, they appear to be overly complex. In most cases, a separate part Date Recue/Date Received 2020-08-07 Docket #: 178-P01.CA

of the isolation tent is designed so that the hands and arms enter, albeit covered, the isolated space occupied by the patient. The patient access areas include materials that are complimentary to the size and shape of the caregivers' hands and arms, but of course this increases the complexity and therefore the cost of manufacturing. Finally, since patients have different sizes and shapes, there is a need for a bespoke isolation tent design which can be modified according to the needs of the patient.
[00017] Thus, there is clearly an unmet need for an improved patient isolation system that not only provides a safe barrier through which caregivers can administer care to the infected patient, but also provides a living volume that improves the experience during a prolonged hospital stay BRIEF SUMMARY
[00018] We have designed a modular isolation enclosure (also called an "isolation tent") for use primarily in hospital environments that significantly reduces, or essentially eliminates, the problems of "patient-to-caregiver" transfer of highly contagious diseases such as those caused by viral, fungal, protozoal, or bacterial infections, which spread either by direct patient contact or via aerosolization of mucosal droplets. Our enclosure provides a very simple, yet effective and reliable way to protect caregivers against airborne infectious disease spread. Our invention provides a novel and unobvious flexible and expandable frame system, which allows rapid expansion and contraction to accommodate patients or beds of various sizes. Unlike conventional static isolation tents, our enclosure addresses the problem of patient access and patient claustrophobia, by allowing the Date Recue/Date Received 2020-08-07 Docket #: 178-P01.CA
SPECIFICATION
caregiver to quickly and easily slide the barrier sheet up over the flexible rod system and then quickly resealing the enclosure using a variety of closing means. In one example the flexible rod system can create a patient-friendly arcuate configuration with significant volume above the patient's body. Moreover, the robust barrier provides improved patient visibility and a significant reduction in patient claustrophobia.
The enclosure provides a universal fit on hospital bed frames via multiple sleeves and/or available adaptor boots for intravenous (IV) poles and/or via altogether flexible frame members or member components. Our design uses clips, bungees, strings, adhesive tape fastener compatible to provide an aerosol (virus) hermetic enclosure so that the patient is enclosed in a sealed environment.
[00019] Since the enclosure is connected directly to the bed, it provides a stable structure, which will not slip-off the mattress and compromise the seal, unlike conventional isolation tents, some of which merely rest on the bed and can move about or even slide off the bed thereby compromising the seal around the patient.
[00020] Another advantage our enclosure has over conventional enclosures is that it can be shipped from a storage warehouse to point of delivery in a very compact, pre-loaded manner. A
unique design of articulated structure (hinges) and/or inserted telescoping posts structure aid the compact storage and transportation.
Upon arrival at the destination, the enclosure can be quickly and safely deployed by two people in less than 30 seconds. Finally, after use, the enclosure can be destroyed by incineration or transported to a landfill site after de-contamination because the materials used in Date Recue/Date Received 2020-08-07 Docket #: 178-P01.CA
SPECIFICATION
construction are low weight, low volume materials and low cost.
Furthermore, a key advantage that our new isolation housing provides is the ability to minimize the height and width of the bed if or when a patient needs to be transported between rooms in the hospital, such as for X-rays and the like which may be located remote from the intensive care unit. Our isolation housing allows for rapid lowering or narrowing of the frame to move through doors or into/out of elevators.
[00021] For extended stay patients, the enclosure can be modified to permit use of a backrest enclosure.
Pull-out end flap allows the enclosure to be further extended to maintain upper body coverage when the bed is adjusted to allow the patient to sit up, while still maintaining a seal therearound.
[00022] Desirably, the enclosure can incorporate existing fan and filter breathing systems via available fasteners and/or adaptor plates and printed cutout templates. This embodiment allows for ambient air to circulate within the enclosure should the patient's condition require such.
[00023] Accordingly, in one embodiment there is provided an apparatus for isolating a patient, the apparatus comprising:
[00024] a frame connected to a first portion of a support body on which the patient is located, the frame having first and second spaced apart rod members sized and shaped for location away from the patient; and [00025] a barrier sheet connected to the frame to define a living volume of a size sufficient to substantially enclose the patient therein, the barrier sheet having a patient access portion to permit a caregiver access to the patient Date Recue/Date Received 2020-08-07 Docket #: 178-P01.CA
SPECIFICATION
[00026] In one example, each of the rod members includes a rod length modifier located at one end thereof to permit the rod member to extend and contract along a path of travel so as to modify the distance between the frame and the patient. The first and second spaced apart rod members includes first and second spaced apart flexible rods, each rod flexible rod having: i) first and second rod length modifiers located at first and second rod ends; and ii)a passageway extending between the first and second rod ends to slidably receive therein the rod length modifiers. The first and second rod length modifiers include a telescoping member slidably mounted in the passageway, the telescoping member being mounted in the passageway using an interference fit so that the telescoping member moves along a restricted path of travel. The first and second rod length modifiers include at least one lock to lock the flexible rod when a desired rod length is achieved. Each of the flexible rods includes a connecting end for connecting the flexible rod to the support body. The connecting end is connected to an intravenous (IV) pole receiver using an interference fit.
[00027] In another example, each of the flexible rods includes a connecting end for connecting the flexible rod to a support body frame.
[00028] In another example, the first and second flexible rods each include at least one first hinge to permit a lower portion of each flexible rod to hinegably move away from the patient. The at least one hinge permits movement of the lower portion of the flexible rod from an upstanding configuration to a orthogonally disposed configuration.

SPECIFICATION
[00029] In yet another example, the first and second spaced apart flexible rods are moveable relative to each other along a longitudinal path so as to accommodate support bodies having different lengths. Each flexible rod is made from a material that is sufficiently flexible to permit forming of the rod into a desired shape to accommodate the barrier sheet and the support body.
[00OO] In yet another example, the first and second flexible rods are arcuate.
[00031] In still another example, the support body is a hospital bed. The hospital bed includes a hospital bed frame, the frame being connected thereinto. The frame is mounted on the floor around the hospital bed.
The support body is a wheeled hospital gurney. The support body is an ambulance stretcher.
[00032] In one example, the barrier sheet is shaped for location over the first and second flexible rods, the barrier sheet being secured to the rod members using one or more sheet connectors. The sheet connectors are clip members located along the length of each rod member to permit a caregiver to sealingly connect the barrier sheet to the flexible rods. The clip members extend around the perimeter of the support body to secure the barrier sheet to the support body. The barrier sheet includes first and second spaced apart sleeves into which the first and second flexible rods are slidably mounted.
The barrier sheet includes first and second spaced apart adhesive strips against which the first and second flexible rods adhere. The barrier sheet is transparent.

SPECIFICATION
[00033] In another example, the barrier sheet includes an inner surface disposed towards the patient, and an exterior side surface disposed outwardly towards the caregiver. The barrier sheet is coated substantially across the entire surface area with an antimicrobial material.
[00034] In another example, the barrier sheet includes a main barrier sheet and an upper body enclosure sheet portion configured to accommodate the patient's upper body when the patient is permitted to sit up, the upper body enclosure sheet being located rearwardly of a moveable upper body portion of the support body.
[00035] In another example, the upper body enclosure sheet portion being of sufficient volume to permit the patient's head and upper body to move between a prone position and an upright position.
[00036] In another example, the barrier sheet drapes substantially over the four sides of the support body and contacts the ground so as to completely enclose the patient and the support body.
[00037] In yet another example, the patient access portion includes a barrier sheet panel that is contiguous with the barrier sheet, the barrier sheet panel having two opposing sides temporarily sealed to the barrier sheet, the barrier sheet panel being slidable along the along the flexible rods to provide a temporary opening of sufficient size to allow the caregiver access to the patient, and thereafter to re-seal the temporary opening.

[00038] In yet another example, the at least one second hinge located between the sleeves to allow collapse of the barrier sheet and the frame for transportation.
[00039] In one example, an air pump and fan is connected to the barrier sheet to communicate ambient air, and carbon dioxide into and out of the living volume around the patient through a filter.
[00040] In still another example, the patient has a highly contagious disease. The highly contagious disease is a viral infection or a bacterial infection. The viral infection is COVID-19.
[00041] Accordingly, in another embodiment, there is provided a method for deploying an isolation enclosure for location around a patient having a highly infectious disease, the method comprising:
[00042] locating first and second caregivers at respective first and second ends of a collapsed and substantially flattened isolation enclosure, the enclosure having first and second spaced apart flexible arcuate-shaped rods, and a barrier sheet connected to the flexible rods; and [00043] applying a pulling force to the respective first and second ends of the collapsed enclosure to fully deploy the enclosure for location around the patient so that the patient has a living volume therearound.
[00044] In one example, the method further comprises:
adjusting the flexible rod member lengths by extending or contracting the rod member lengths using rod length modifiers located at first and second rod ends so that the barrier sheet

[00045] Accordingly, in another embodiment, there is provided a two-dimensional pattern for assembling an isolation enclosure to isolate a patient, the patient having a highly contagious disease, the two-dimensional pattern comprising:
[00046] a sheet of transparent material having a generally rectangular-shaped central panel and first and second spaced apart joints;
[00047] first and second end panel sheets each connected to the respective spaced apart joints;
[00048] first and second spaced apart sleeve attachment portions located on one side of the transparent material and shaped to receive therein respective first and second flexible rods; and [00049] first and second substantially rhomboidal spaced apart panels extending away from the rectangular-shaped central panel, the sleeve attachment portions each extending from the rhomboidal panels across the rectangular-shaped panel for receiving therein the flexible rods during assembly of the isolation enclosure.

Examples of highly contagious diseases include, but are not limited to, coronavirus, SARS, chickenpox, measles, whooping cough, tuberculosis, diphtheria, and Ebola.

[00095] Still referring to FIG. 1, the frame 14 includes two flexible rod members 24, 26 which are sized and shaped for location away from the patient 12. The flexible rod members 24, 26 are made from a flexible material such as for example, Polyvinyl Chloride (PVC) or cross-linked polyethylene, which permits forming into various shapes. To provide additional strength to the rod members 24, 26, a fiber glass rod insert can be used. While it is possible to use fiber glass rods as the frame system 14, their inherent brittle nature and potential for "whiplash" makes fiber glass rods hazardous for use. As used in the examples herein, the rod members 24, 26 are curved into an arcuate shaped upper portion 27 for reasons that will be become clear below.

[00095] Still referring to FIG. 1, the frame 14 includes two flexible rod members 24, 26 which are sized and shaped for location away from the patient 12. The flexible rod members 24, 26 are made from a flexible material such as for example, Polyvinyl Chloride (PVC) or cross-linked polyethylene, which permits forming into various shapes. To provide additional strength to the rod members 24, 26, a fiber glass rod insert can be used. While it is possible to use fiber glass rods as the frame system 14, their inherent brittle nature and potential for "whiplash" makes fiber glass rods hazardous for use. As used in the examples herein, the rod members 24, 26 are curved into an arcuate shaped upper portion 27 for reasons that will be become clear below.
