This document relates to devices and methods for human patient transport.
Transporting patients in emergency situations poses a difficult challenge for responders, and no current tools exist for effective transport in ranging situations. Patient transport issues during emergency operations and daily transfers show planning and response deficits, including; 1) providing continuity of care for increased customer satisfaction by ensuring that the patient chart/information/medicines and other items follow the patient; 2) transferring biological material in patient linens during transfers from one facility to another facility, leading to nosocomial and iatrogenic infections; 3) protecting against linen loss by maintaining the proper inventory of linens, which are often lost during transfers causing increased costs to the hospital; and 4) transporting patients in emergency situations and evacuations. The disclosed invention meets these needs and fulfills many regulatory agency requirements.
The current invention is a multifunctional blanket intended for transporting patients. While the invention can be applied to multiple patient situations, one specific application is for transporting patients by air medical or other emergency services. The multifunctional evacuation blanket fits in a carrier to become an evacuation blanket. Such carriers are generally strong blankets reinforced with heavyweight polypropylene webbed straps, wherein the straps also extend beyond the edges of the strong blanket to act has handles. The multifunctional evacuation blanket would also function as a blanket for a stretcher.
In one aspect, an evacuation blanket is provided for evacuating patients. The evacuation blanket includes an absorbent layer and a top layer, the top layer further including two or more pockets wherein at least one pocket is a transparent pocket. The evacuation blanket further includes a tear away band configured to be detached from the evacuation blanket by a pull from a human responder's hand pull, such as by a perforated connection. The wrist band has an identification component corresponding to the evacuation blanket and is configured to attach to a patient. An ideal identification element is a wrist band, but the invention is intended to include an ankle band or any other item for attaching to a human patient. The evacuation blanket also includes one or more flaps configured to cover one or more of the one or more pockets. The flaps can be closed over the pockets with a plurality of coupling points that attach to the pocket or evacuation blanket. These coupling points are preferably hook and loop commonly known as Velcro.
In another aspect, the evacuation blanket includes a slit located substantially in the center of the evacuation blanket.
In another aspect, the evacuation blanket is substantially rectangular, with the flaps being parallel to the longer side of the substantially rectangular evacuation blanket.
In another aspect, the plurality of blanket coupling points are configured to attach to a plurality of carrier coupling points via a hook and loop mechanism.
In another aspect, the flap coupling points couple to the blanket coupling points by hook and loop coupling.
In another aspect, the evacuation blanket further includes at least two transparent pockets and at least two non-transparent pockets.
In another aspect, the evacuation blanket further includes a carrier with an absorbable pad, wherein one side of the evacuation blanket is permanently fixed or attached to a corresponding side of the carrier, such as by having the two sewn together. Alternatively, the blanket and carrier may be one continuous sheet. On the side of the evacuation blanket opposing the side that is permanently attached, there are a plurality of carrier coupling points that are configured to attach and detach from the plurality of blanket coupling points. These coupling points are structured and configured to attach and detach easily, such as with a hook and loop connection. The carrier includes reinforcing straps to provide strength to support the weight of a human patient, such as when that patient is transferred from a stretcher to a hospital bed.
In another aspect, the top of the evacuation blanket is made of a material capable of being written on with pencil and pen, such as polypropylene.
In another aspect, the tear away connector is located inside a transparent pocket.
In another aspect, the tear away band corresponds to evacuation blanket with a corresponding bar code. This does not necessarily need to be the same bar code, but the identification means on the wrist band must correspond to the identification means that remains on the evacuation blanket.
In another aspect, the evacuation blanket is comprised of a waterproof material and has a plurality of pockets, at least some of which are configured to close, wherein at least one of the pockets is transparent, and wherein the evacuation blanket has an identification element that is configured to be attached to a patient and is further configured to be associated with the evacuation blanket so that a patient can recover any belongings that may have been placed in any of the pockets after the patient is separated from the evacuation blanket.
In another aspect of the invention, a method of a responder or responders evacuating a patient using the evacuation blanket is provided. The various steps can be performed in various orders.
The method includes a responder removing belongings that may complicate the performance of emergency medicine, such as jewelry, and placing those belongings in one of a plurality of pockets on the evacuation blanket. Most preferably, personal belongings would go in opaque pockets.
The method also includes the step of a responder will detach an identification component from the evacuation blanket and fix it to the patient, such as by attaching a wrist band or ankle band. When the patient is ultimately delivered to a destination, such as a hospital providing certain care not available at a first location, the patient is typically delivered to a bed and separated from the evacuation blanket. This makes it important to later match the blanket to the patient.
The method also includes the step of placing the patient onto the carrier portion of the evacuation blanket while the top layer has been peeled away or pulled away such that the patient is not on top of the blanket. This allows for the top layer to be pulled away from the side where the top layer is attached to the carrier and over the patient. The top layer is then connected to the carrier on the side that is opposite to the side where the carrier portion is permanently sewn or fixed to the top layer. The patient now is somewhat sealed on each side and sandwiched between the top layer and carrier. In the preferred embodiment, the patient contacts absorbable pads that are integrated with the top layer and carrier with one beneath the top layer and one above the carrier.
The method may also include the step of performing some medical care during transportation, such as triage. Medical information associated with this medical care can be inserted into the transparent pocket. This will allow medical responders at the patient's destination to easily see the medical information associated with the patient.
