Disposable Bio-secure Environmental Unit

CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application is a Continuation in part of pending U.S. Non-Provisional patent application Ser. No. 14/756,979 "Disposable Bio-Secure Environmental Unit", filed on Nov.4^th, 2015 and to pending U.S. Provisional patent application 62/993,288 "Disposable Bio-Secure Environmental Unit" filed on March 23^rd, 2020, the disclosure of both which is herein incorporated by reference in their entirety.

PATENTS CITED:

[0002] The following documents and references are incorporated by reference in their entirety, Ellen (U.S. Pat. Appl. No. 2006/0020159), Fujimoro et al (U.S. Pat. No. 9,155,309), Hardin (U.S. Pat. No. 9,038,214), Yachi et al (U.S. Pat. No. 6,966,937) and Gauger et al (U.S. Pat. No. 6,321,764).

FIELD OF THE INVENTION

[0003] This invention relates to patients that are suspected of infectious and/or contagious disease; and, more particularly to such patients temporaiy isolation while being transported, seeking entrance to a hospital, clinic or doctor's office, and/ or requiring an upgrade of isolation conditions within a facility.

DESCRIPTION OF THE RELATED ART

[0004] Many hospitals, clinics, doctor's offices, and other suchfacilities have found it necessary to screen for Ebola, COVID-19 and other contagious diseases. Once a patient seeking entrance to the facility says "yes" to screening questions, concerning Ebola and/or such other contagious diseases, the patient must be isolated in a negative pressure room and staff must don appropriate Personal Protective Equipment (PPE) and must have a place, such as an anteroom, available to dress and undress. At that time there also arises a need for a patient transport unitthat facilitates transport of such a patient.

[0005] Patient isolation units, such as the one shown and described inUSA Patent 6,966,937 to Takashi Y achi, et al, require use of a sheet of flammable resin as part of anendosureortent within which a patient can be examined. The erection of the enclosure is time consuming. Its flammability may prove to be unacceptable and dangerous due to ifs flammability.

[0006] USA Patent 9,038,214, issued on May 26, 2015, on the other hand, provides a plurality of privacy screens that are to be hung about a bed or gurney to accommodate HIPPA requirements.

The illustrated and described screens are unacceptable because the patient cannot see out, nor can attending medical personnel see in or attend to the patient without displacing one or more of the screens.

[0007] USA Patent 9, 155,309, issued on October 13,2015 is directed to a virus inactivating sheet and would prove unacceptable for patients seeking entry to a medical facility.

[0008] What is needed, is a low cost, disposable bio-secure environment to temporarily hold, and where required to transport, patients who are suspected of having an infectious or contagious disease requiring contact, droplet and/or respiratory isolation precautions. With such a unit, upon initial presentation of such patients, health care facilities would be able to safely isolate such patients while they are initially assessed and then, if need be, transported to an appropriate biosafety level unit.

It will be clearly understood that, although a number of prior art publications are referred to herein, this reference does not constitute an admission that any of these documents form part of the common general knowledge in the art.

[0034]As used in the specification and claims, the singular forms "a", "an" and "the" include plural references unless the context clearly dictates otherwise. For example, the term "a transaction" may include a plurality of transaction unless the context clearly dictates otherwise. As used in the specification and claims, singular names or types referenced include variations within the family of said name unless the context clearly dictates otherwise.

[0035]Certain terminology is used in the following description for convenience only and is not limiting. The words "lower," "upper," "bottom," "top," "front," "back," "left," "right" and "sides" designate directions in the drawings to which reference is made, but are not limiting with respect to the orientation in which the modules or any assembly of them may be used. [0036] It is acknowledged that the term 'comprise' may, under varying jurisdictions, be attributed with either an exclusive or an inclusive meaning. For the purpose of this specification, and unless otherwise noted, the term 'comprise' shall have an inclusive meaning— i.e. that it will be taken to mean an inclusion of not only the listed components it directly references, but also other non-spedfied components or elements. This rationale will also be used when the term 'comprised' or 'comprising' is used in relation to one or more steps in a method or process.

[0037]The present invention is generally shown, a disposable bio-disposable environmental unit (FIG. 1) (DBEU) 100 for the transporting/temporary housing of patients. The unit is based on an adjustable frame 106 that is designed to securely attach, lay or fit onto a gurney, bed, table, slab or other suitable support surface 102. The adjustable frame 106 supports and is attached to a containment tent or endosure 104 along the 'edges' of the volume formed by the endosure 104, positioned and secured in place on top of a support surface (such as a gurney 102), so that the patient may lay on a mattress placed inside the endosure 104 volume. (Again, while shown positioned on a gurney 102 it may also be so positioned on a stretcher, hospital bed, or other strudure constructed to receive the cabin or frame 106 or the like).

[0038] In one embodiment, the adjustable dimension rigid frame 106 integrates onto a stretcher, bed, platform or gurney 102. In one embodiment 400 (FIG. 4), this is done by pladng the frame base 402 onto receivers 202, 404 (FIG. 2/FIG. 4) that are fitted onto the bed, stretcher or other available and fitted out platform. The containment endosure 104 is a disposable sealed endosure, in one embodiment built of a 20-mil dear poly (or similar). The enclosed volume within said endosure 104 has a 404, sidewalls 108, end walls 214 and ceiling 204, all easily secured onto the frame side members 106 and end cross member 220. The bottom of the endosure is preferably filled with a mat/pad/mattress 124 placed for the patient inside the endosure 104.

[0039] The bag, tent or endosure 104 is supported by the external frame 106 via multiple mechanical attach components (e.g. Hooks and loops (such as VELCRO) straps, rope, clips, carabiners dips, etc. 116/118) located along length/width/height of the endosure 104 to couple along the length/width/height of the frame members. These mechanical attach components may be Hooks and loops straps, rope, dips (to suitable openings within the bag edge) or any other suitable easy on/off attachment component. [0040] In one embodiment, there is a length adjustment member 114/210 at each of the frame 's upper lengths (one on each side) so that the frame overall length (along the bed side) can be adjusted when installing the frame base 402 into the receivers 202/404 on the gurney or bed. In one embodiment, the sliding of one tube within the other is controlled by a friction component, such as with the addition of an Allen set screw in an opening between the inner and outer tube, so that insertion of the set screw creates friction. In another embodiment, this may be accomplished by a set pin or via a rotating friction sleeve or similar device.

[0041] As seen in FIG. 4, all or portions of the frame 406 coming across said receiver, so that all or portions of it may then be secured (either via friction, set screws or pins, such as cotter pins). Similarly, there is a width adjustment mechanism through the presence of a width adjustment member 114/210, similarly equipped so that once the proper width is obtained, the distance may be secured via securing components such as friction and/or pins. Finally, in one embodiment, each of the unit's legs 118 may be equipped with similar adjustment/securing components, so as to adjust the overall height of the frame with relation to said gurney, surface or bed. In one embodiment, the securing component is available only on one member, with the opposite member being able to freely slide.

[0042] Access into the interior of the enclosure unit 104 is accomplished through a number of resealable openings. The two primary ones are the patient entry/exit opening 112, which is formed by an inverted 'U' (n) shape formed by a resealable edge (a zipper, Hooks and loops or other similar resealable 'tongue'). Such a shape has the advantage of 'sticking out' with the interior of the unit as the patient is placed into the enclosure 104, so that any contact with the patient (through sweat, skin, blood or any other patient fluid) will result on the infected area of the enclosure remaining towards the interior/patient volume.

[0043] One or more additional entry points 302 are similarly configured so that outside caregivers may pass food/fluid/supplies/diapers/medications or other items from the outside to the patient and/or in another direction. These entry points 302 (FIG. 3) may be located anywhere along the side walls 108 and/or the bottom/end walls 216. In addition to the entry points, there may be one or more pairs of integrated sealed port glove access points 304/306, provided for patient care processes by personnel outside the enclosure 104. [0044] Smaller versions of these ports would be provided for monitoring cables, oxygen and IV tubing. In one embodiment, an integrated IV bag holder is provided inside the enclosure 104. Alternatively, openings for fluid entry into the enclosure 104 may be provided.

[0045] A critical function of any DBEU device is the ability to adjust the positive/negative air pressure within the unit's enclosure 104. This is accomplished by the integrated battery powered 208 negative or positive pressure ventilation units 206, which go through the enclosure wall at either pre-drilled openings and or may simply plug into the enclosure material. These units are equipped with High Efficiency Particulate Air (HEP A) filtered exhaust. In one embodiment, such a setup with 3 units 206 would result in an air flow rate resulting in 13.1 changes of interior volume air per hour and minimum interior negative pressure of -3 inches of water column.

[0046] In one embodiment 200, the ventilation units 206 are supported on a frame 212 hanging from the top cross member 214, so that when the overall length of said member 214 (which determines the width of the frame 104) is adjusted, the frame 212 simply slides along said member 214. In another embodiment 500, the ventilation units 206 are mounted on a sliding frame 502 attached to the vertical frames 216/218, so that as the length of the top cross member 214 is adjusted (via the adjustment component 114/210) the sliding frame 502 complies (FIG. 5). In another embodiment, this is accomplished by mounting the fixed length frame 502 on sliding brackets 504.

[0047] Referring to FIG. 12, we see an embodiment of a feature of the enclosure 104 that is particularly beneficial when dealing with negative pressure situations (such as those required for treatment of patients infected with Ebola or COVID). The enclosure 104 forms a pneumatically sealed volume, attached to the frame 106 via the suitable mechanical attach components 116/118. These components are either part of the enclosure, or attached/bonded to it. In this fashion the enclosure 104 hangs/floats suspended from the frame 106, and its lower surface is held down via the mattress 124 which has the patient lying in it, inside the enclosure 104.

[0048] All positive pressure applications will have the enclosure 104 balloon until it meets or slightly exceeds the enclosure dimensions 104, which will be sized to the frame 106. A major situation is encountered when negative pressure is required. In effect, the atmospheric pressure would push onto the enclosure 104, potentially shrinking it. To counter some of these effects, Hooks and loops strips 110/218 are attached/bonded to the walls of the enclosure 104 are used. By securing these strips 110/218 to each other across the frame member 126 that separates them with one or more horizontal strips 1202/1204, the skin of the walls will be stretched and kept from suctioning itself in, resulting in a larger internal volume for the patient/caregivers. This procedure may also be used for the enclosure ceiling 204 both at the corners and/or the center, again, ensuring the comfort of the patient.

[0049] Referring to FIG. 13, we see 1300 the frame of the DBEU 100 inside which the enclosure 104. In one embodiment, when negative pressure will be used (similar to 1200 in FIG. 12) an alternate top arrangement may be used to place the roof/ceiling 204 of the enclosure 104 in tension. As seen in FIG. 14, we use 1400 a Hooks and loops strip 1402 attached to the outside of the enclosure ceiling 204 along the length of said ceiling, which is then laced to Hooks and loops straps along both the side 1404 and the ends 1406 along the frame side members 106.

[0050] In FIG. 15, we see the other side, with particular focus on the access

Example

[0051] Perhaps an example of the use and operation of the Environmental Unit helps understand its unique capabilities. Firstly, the person setting up the Environmental Unit (Dr., Nurse, Technician, or other trained person assembles the: transport monitor and cords; blood pressure cuff; ECG electrodes (for chest); Pulse Ox probe; oxygen tubing; nasal canula; and IV tubing (if needed).

[0052] Next the cords are placed by: opening one or more of the access openings 302, pulling the lining outward; thread monitoring cords through the appropriate port or opening 302; twist the lining around the cords; tape the lining to the cords forming a seal; push the cords and lining inward; ensure all monitoring probes are connected to cords; repeat process for Oxygen and IV tubing on the same or another opening 302.

[0053] The gurney, already prepared with an Environmental Unit, is opened by: downwardly unzipping the one or more zippers 122 located on the entry /exit opening and having covers 112 which ensures when opened, the flap 120 is lowered so that the patient may only contact the portions of the flap that will face the inside of the enclosure 104. [0054] Next, the status of the batteries 208 is checked, and if necessary, they are replaced. The ventilation units are tested 206, and made ready for operation. The isolation Gurney is now ready for use for a patient. The patient should have been or should now be Informed of the use of the Isolation transport unit in order to facilitate transport to an isolation unit.

[0055] The patient should next enter the isolation gurney through the entry 120. Closing the isolation containment enclosure 104 closure is accomplished by grabbing the closure zipper 122 closing it and if necessary, sealing the zipper with additional covers 122 having Hooks and loops strap, strip or tape. In one embodiment (FIG. 15 - 16), the zipper 122 is double pull, so it may be closed/opened both from the inside and the outside.

[0056] The other entries 302 are available in the event a patient needs additional supplies. In one embodiment, these openings are double sealed, so that no air may escape/enter as objects are passed into the enclosure 104 interior. This is accomplished by a double zippered opening. When passing something inside, the process begins by opening the outside zipper to the transfer pocket. The object is placed into the pocket the pocket is zipped closed. The patient thereafter unzips the inside pocket and can obtain the item; thereafter zipping the pocket closed. It is important to ensure that the patient zips the inside pocket closed.

[0057] As seen in FIGS. 15 - 16, the access entry 302 may be done with simple zippers and Hooks and loops covers. In one embodiment, the entry 302 has pockets having zippers inside 1602 and outside 1604 to allow access both from the inside and the outside.
