BACKGROUND

1. The Field of the Present Disclosure

The present disclosure relates generally to covers used as a protective layer on patient transport devices, such as gurneys and stretchers. More particularly, the present disclosure relates to a cover adapted to serve not only as a protective layer but also to provide other advantages to the patient and health care providers.

2. Description of Related Art

Various devices have been used to transport patients from one location to another. These devices are used in a variety of circumstances, such as within a hospital, or for transportation to, within, and from an emergency vehicle such as an ambulance or helicopter. These devices often have a number of handles, handholds, and attachments creating an odd shape. Such devices often have a mattress-like portion for the patient being transported to rest on. Some type of bedding might be provided, designed to prevent contamination of the mattress area and protect the patient from cross-contamination. However, the shape of the patient transport device, along with the handles, attachments, and perhaps seat belts (for ambulance transport) can create an undesirable situation where a protective barrier in the shape of an ordinary sheet will not cover the entire area of the device where a patient may have contact, such as the handles and seat belts, which leads to the possibility of contamination of the device and cross-contamination with future patients transported by the device.

There have been a variety of types of bedding used for these devices, many of which are now disposable so as to provide a clean device and prevent cross-contamination and infection for subsequent patients. However, customization of covers for patient transport devices have not always kept pace with devices themselves. In addition, the covers for the patient transport devices have been created with the end of serving merely as a barrier between the patient and the device. However, it is unrecognized in the art that a cover can advantageously serve many more functions in accordance with the needs of a patient and the needs of health care providers.

In view of the disadvantages and unrecognized needs present in the already available devices, what is needed is a cover which serves to prevent contamination, and also serves other purposes for the patient and health care providers, depending on the needs of the patient and the providers. Below, disclosure is provided for a single use protective cover for patient transport device which is specifically fitted to a number of patient transport devices to better prevent contamination, and which also provides additional benefits to individual patients being transported and health care providers using said device.

The features and advantages of the present disclosure will be set forth in the description which follows, and in part will be apparent from the description, or may be learned by the practice of the present disclosure without undue experimentation. The features and advantages of the present disclosure may be realized and obtained by means of the instruments and combinations particularly pointed out in the appended claims.

DETAILED DESCRIPTION

For the purposes of promoting an understanding of the principles in accordance with the present disclosure, reference will now be made to the embodiments illustrated in the drawings and specific language will be used to describe the same. It will nevertheless be understood that no limitation of the scope of the disclosure is thereby intended. Any alterations and further modifications of the inventive features illustrated herein, and any additional applications of the principles of the disclosure as illustrated herein, which would normally occur to one skilled in the relevant art and having possession of this disclosure, are to be considered within the scope of the disclosure claimed.

In describing and claiming the present disclosure, the following terminology will be used in accordance with the definitions set out below. As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” include plural referents unless the context clearly dictates otherwise. As used herein, the terms “comprising,” “including,” “having,” “containing,” “characterized by,” and grammatical equivalents thereof are inclusive or open-ended terms that do not exclude additional, unrecited elements or method steps.

As used herein, the term “patient transport device” refers to any device used specifically to move a patient while allowing the patient to recline or lie down. This can include devices such as gurneys and stretchers used in vehicles such as ambulances, as well as devices such as mobile hospital beds which may be stationary for most of the time, but are designed to easily move.

Applicant has invented a protective cover for patient transport devices. Said cover is designed to act as a beneficial cover for a patient transport device, protecting the device itself and providing comfort and protection for the patient and benefitting the associated health care workers.

The protective cover is comprised of at least an impermeable base layer and an absorbent layer on top of the impermeable base layer, as diagrammatically shown in the cross sectional view of FIG. 7. The impermeable base layer 701 is form fitted to the patient transport device 700 and is impermeable to fluids. This layer 701 prevents fluids from contaminating the patient transport device and any pad attached to the device. The absorbent layer 702 is on top of the impermeable layer and is designed to trap and retain fluids. Thus in the case of a fluid contacting the protective cover, it is absorbed into the absorbent layer 702, and the impermeable layer 701 below prevents whatever is not absorbed from coming into contact with the patient transport device 700 and pad, as well as preventing whatever fluid is absorbed from draining or being pressed out of the absorbent layer 702 and contacting the patient transport device or pad. It should be noted that the width of the layers in FIG. 7 is not intended to limit the disclosure in any way. The width of the layers may need to be greater or lesser in proportion to the other layer in order to properly perform its function.

In one embodiment of the present disclosure 100, shown in FIG. 1, the protective cover may be shaped so as to precisely fit on a variety of patient transport devices, including different gurneys or stretchers. One exemplary patient transport device is shown by the outline 101 represented in FIG. 1. It will be appreciated that the dimensions (inches) illustrated in FIG. 1 are merely exemplary of those dimensions adapted for the patient transport device 101 but using the disclosure provided herein many different embodiments can be arrived at for many different patient transport devices beyond the particular patent transport device 101 represented in FIG. 1.

As illustrated in FIG. 1, the cover is shaped so that it securely covers the top surface of the patient transport device fitting snugly over the patient transport device, with one or more extensions 102 fitting around the various handles and extensions which may be part of the patient transport device. These extensions 102 may include covers for the railings 103 as seen in the FIG. 1. In one embodiment, the railing cover 103 is an impermeable layer which extends to cover the railings all around the patient transport device. This creates an area between the railings and the mattress which catches fluids, preventing fluids from entering the areas between the mattress and the railing, and preventing the contamination of other parts of the patient transport device which the patient does not contact. One embodiment of the cover may include a head cover 104 and a foot cover 105 which are shaped to cover and go around the head and foot of the device, providing an impermeable protection to these areas which may not be flat and thus are not easily covered by a previously available protection device.

The cover 100 can be attached to the patient transport device by whatever method is appropriate. In one embodiment, the cover may have a stretchable, elastic portion at the edge of the cover which is meant to fit around the bottom of the gurney or stretcher and secure the cover to the stretcher. In another embodiment, the cover may be secured by straps which wrap around a gurney.

In addition, the cover is designed to be completely disposable, allowing a new, clean protective cover to be utilized with each patient or each time a new, clean protective cover is desired.
