Bed drying device, UV lights for bedsores

TECHNICAL FIELD

The presently disclosed and claimed disclosed technology generally relates to a method and apparatus for drying a person in a lying position, and more particularly to a device for maintaining adequate skin dryness and skin treatment during extended hospital stays.

BACKGROUND

People who are confined to a bed for extended periods of time can develop moisture build up on their skin where the skin does not have sufficient exposure to dry. Similar to being in a pool for extended periods, the skin in these locations can become soft. Additionally, the moisture build up can become a bacterial breeding ground. The skin in these areas is frequently under constant pressure from the patient's body weight.

These areas of skin can begin to stick to the bed and tear away from the person. The tearing can result in open sores which are painful and can bleed significantly. Once the open sores are present, there is a significant risk of infection. These sores require additional care and expense that would not be necessary if the bed sores had been prevented beforehand. Treatment and prevention of bed sores can require specialized beds or having the patient leave the bed for extended periods of time. If a specialized bed is used the treatment can be expensive but can be the only choice if the patient is unable to leave the bed.

Hospital patients are sometimes confined to long periods of bed rest due to causes including surgical recovery and coma. The patient's condition, either conscious or not, often requires the patient to lie in substantially one position for extended periods of time. These extended sedentary periods place hospital patients at an increased risk of bed sores, related infection, and medical care that otherwise would not be necessary.

SUMMARY OF THE DISCLOSURE

The purpose of the Abstract is to enable the public, and especially the scientists, engineers, and practitioners in the art who are not familiar with patent or legal terms or phraseology, to determine quickly from a cursory inspection, the nature and essence of the technical disclosure of the application. The Abstract is neither intended to define the inventive concept(s) of the application, which is measured by the claims, nor is it intended to be limiting as to the scope of the inventive concept(s) in any way.

Still other features and advantages of the presently disclosed and claimed disclosed technology will become readily apparent to those skilled in this art from the following detailed description describing preferred embodiments of the inventive concept(s), simply by way of illustration of the best mode contemplated by carrying out the disclosed technology. As will be realized, the inventive concept(s) is capable of modification in various obvious respects all without departing from the disclosed technology. Accordingly, the drawings and description of the preferred embodiments are to be regarded as illustrative in nature, and not as restrictive in nature.

The present disclosed technology consist of a method and apparatus for treating and preventing bed sores and the associated issues, including insufficient drying and bacterial breeding in a bed-ridden hospital patient. The present disclosed technology dry the patient as well as destroy the harmful bacteria present on a person's skin.

The apparatus utilizes a forced air source, such as a fan, and a UV light source. Often the patients are unable to make significant movements. The apparatus allows the patient to make a minimal movement to expose the patient's skin. The fan and UV light are able to rotate around a bed to a position where the bed patient can roll onto his side or stomach to expose the skin at risk of bed sores and infection, typically the patient's back, to the forced air and UV light. Once the skin is exposed, the apparatus can be set up so that the forced air source and UV light source can be positioned above the patient or to the side of the patient as necessary.

This method of drying a patient and killing harmful bacteria is accomplished by utilizing a drying mechanism, such as a fan, in addition to a UV lamp. The method consists of a first step of positioning the patient on his side or stomach in order to expose the area of skin to be treated. The second step of the method is positioning a device such that the UV lamp and fan extend over, or around, the patient bed. The third step of the method is rotating the lamp and fan assembly to be directed at the area of skin to be treated. The fourth step is activating the lamp and UV light assembly for sufficient time to effectively treat the area.

DETAILED DESCRIPTION OF THE EXEMPLARY EMBODIMENTS

While the presently disclosed technology are susceptible of various modifications and alternative constructions, certain illustrated embodiments thereof have been shown in the drawings and will be described below in detail. It should be understood, however, that there is no intention to limit the inventive concept(s) to the specific form disclosed, but, on the contrary, the presently disclosed and claimed disclosed technology are to cover all modifications, alternative constructions, and equivalents falling within the spirit and scope of the inventive concept(s) as defined in the claims.

The disclosed device is a skin treatment tool with a therapeutic light and fan, which is made to treat a patient in a bed. The device is made to be placed over a bed, with the patient lying face down or on a side. The light and fan dry the skin and treat the skin with beneficial wavelengths of light. FIG. 1 represents a preferred embodiment of the presently disclosed and claimed technology. FIG. 1 illustrates a patient drying device 10 having a frame 16, the frame having a base 12, wheels 14, vertical support 20, horizontal support 30, and forced air fan 18 and UV light source 34 located in a treatment head 28. In a preferred embodiment the patient drying device 10 utilizes four wheels 14, attached near the four corners of the underside of base 12. A fifth wheel may be placed in a support location on the base 12. It is to be noted that horizontal support arm 30 can extend over a bed horizontally, or may be placed at the side of a patient as in FIG. 4, and the treatment head 28 may be rotated at the end of the horizontal support arm 30. The wheels 14 can be of any type mountable to a base, with castor wheels being preferred. The wheels 14 can be constructed with any material that allows for free rotation, including metal, plastic, or a combination of materials. Shown in FIG. 1 is a bed 36, and shown in FIG. 2 is a patient 38 in the bed 36.

Base 12 can have extending pieces 40, on which wheels 14 are placed. The base 12 may have rounded corners for improved safety and portability. The base 12 is preferably metal, such as stainless steel, but other materials can be used to provide sufficient strength and stability for the treatment head 28. Similarly, the size of the base 12 must be sufficiently extendable to support the patient drying device 10 with the treatment head 28 extended in any allowable direction. In a typical configuration of the device 10, the base is approximately 23.5 inches long and 12 inches wide. The vertical support 20 would typically extend to about 59 inches high, and the treatment head 28 is about 5.5 inches wide and 24 inches long. In one embodiment, the extending portions 40 of the base 12 extend to 37.5 inches.

Attached to the top of base 12 is vertical support 20. Vertical support 20 extends from base 12 in a substantially vertical direction. Vertical support 20 may have telescopic capabilities to adjust the height of the treatment head 28 to accommodate larger patients and higher beds. Incorporating telescopic capabilities into vertical support 20 also allows for easier storage and transport of patient drying device 10 as well as personalized treatment for different sized patients.

Attached to the top of vertical support 20 is horizontal support arm 30. Braces 22 may be attached to the vertical support 20 for additional support of the horizontal support arm 30. The treatment head 28 can be attached to horizontal support arm 30 by a movable joint 42, to allow the treatment head 28 to be positioned as shown in the figures. Another flexible joint 44 can allow the treatment head to be placed in a vertical position for storage or treatment, as shown in FIGS. 5. For improved functionality, horizontal support arm 30 can also have telescopic capabilities. In this manner it would be possible to treat both sides of a patient without moving the patient drying device 10 to the opposite side of the patient bed.

Attached to, or near, the end of the horizontal support arm 30 opposite of vertical support 20 is treatment head 28, which contains a forced air fan 18 and UV light source 34. The treatment head 28 can be mounted to rotate along the axis of horizontal support arm 30 to allow a user freedom to direct the forced air and UV light source in various ways. FIG. 1 also shows horizontal support 30 incorporating a joint 44 within the length of horizontal support 30. While different types of joints can be used, a ball joint is preferred for increased selection in the positioning of forced air fan 18 and UV light source 34, incorporation of joint 42 allows the treatment head 28 to be positioned either above a patient or to the side of the patient. For example, it is desirable to have forced air fan 18 and UV light source 34 directed away from vertical support 20 when treating the near side of a patient. It is also desirable to position forced air fan 18 and UV light source 34 toward vertical support 20 in order to treat the far side of a patient without having to move the entire patient drying device 10.

FIG. 2 represents a rear view of the presently disclosed technology, which also shows a side view of the patient. FIG. 2 shows the addition of braces 22. While not always necessary, braces 22 are added to reduce stress on the vertical support 20 and increase rigidity of the apparatus.

FIG. 3 shows a top view of the presently disclosed technology. FIG. 3 illustrates one embodiment where base 12 is substantially longer than it is wide with horizontal support arm 30 extending in a substantially similar direction. In FIG. 3, the patient is lying on his/her stomach, with the treatment head 28 over an area of the torso to be dried or treated with UV.

FIG. 4 represents a side view of the presently disclosed and claimed inventive concepts. FIG. 4 illustrates one embodiment with a patient lying on his or her side on a bed. FIG. 4 shows the vertical support 20 with telescopic abilities. Vertical support 20 can be locked in place with height adjustment knob 26. Other locking mechanisms can be used also, including flip locks or hole and pin systems.

FIG. 4 also shows treatment head 28 in a horizontal position next to the back of a patient laying on his/her side. A suitable UV light source in the treatment head 28 is a (brand) Phillips (model) Narrowband TL which uses a 20 watt UV heat lamp. A suitable force air fan in the treatment head 28 is a (brand) Dayton (model) Square Axial fan, which has multiple speed settings. The treatment head 28 has a cover with slots through which air and UV light is directed to the patient.
