Medical protective wrap
Medical protective wraps made using a liquid impermeable, stretchable polymeric material which provide a watertight seal and barrier to protect wounds from contamination because of microbes, dirt or infiltration of water during bathing whilst not constricting blood circulation into the healing process. The protective wraps include a liquid impermeable stretchable polymeric sheet of a sufficient length to wrap around the entire body part at least one time. Positioned together opposing peripheral borders of the polymeric sheet are sealing cuffs having reduced stretchability relative to the sheet. Additionally, there are second and first terminal borders running transverse to the longitudinal axis of their peripheral borders. A fastener is connected to the initial terminal edge that simplifies the sheet into the human body and the next terminal is secured into the sheet after at least one wrapping of the sheet around the entire body part.

After surgery or a serious injury a significant concern of most patients is the ability to go back to normal routines including bathing or showering. This often poses a difficulty because the wound has to be maintained in a sterile state withoutcontamination from water or dirt. In earlier times many watertight dressings have been developed but these waterproof protective covers can also restrict movement of the involved body part. This restriction of motion may interfere with progress of arehabilitation application especially if waterproof protection is necessary for therapeutic sessions in a whirlpool.
Average of the most common forms of protection against exposure to external dirt and water to get an injured limb include bag-type structures. Some patents representative of this type of structure are as follows: U.S. Pat. No. 4,523,586 into Couriissued Jun.. 18, 1985; U.S. Pat. No. 5,152,282 into Elphick et al issued Oct.. 6, 1992; U.S. Pat. No. 5,395,302 into Botha et al issued Mar.. 7, 1995; and U.S. Pat. No. 5,720,712 into Joy et al issued Feb.. 24, 1998. But this kind of coveringpresents many disadvantages. As an example, if the wounded area involves a arm then positioning of a bag-type structure over the arm removes the use of the encased hand for engaging in normal routines. In the instance of a leg, then the foot isvirtually immobilized from the bag-type structure. Additionally, movement is difficult and dangerous due to the chance of further injury as a result of potential threat of slippage on the tote structure.
Furthermore, a number of the protective mats currently accessible use elastic closures or even some type of constriction on the peripheral edges of the wrapping or bag to maintain a watertight seal. Examples of this type of closure are shown in U.S.Pat. No. 2,911,974 into Spence issued Nov.. 12, 1959 and Botha et al supra. It’s thought that restrictive elastic closures may be counter-productive to recovery because the additional strain on the veins underneath the elastic closure can cause areduction of blood circulation into the region thereby slowing the recovery procedure.
Other kinds of protective wraps utilize a strip of adhesive tape or a sticky strip onto the peripheral edges of this protective covering for protecting an injury or incision, such as that disclosed in U.S. Pat. No 1,707,515 to Evans issued on May29, 1926. But this type of adhesive strip can introduce a high amount of discomfort to the patient when the cover or wrap is removed especially if the tape adheres to a patient’s entire body hair. What’s more, there may be seal leakage at particularsections that are worried during body motion allowing water infiltration to the wound website.
Some protective covers can present problems in the application process, such as revealed in Elphick et al and Botha et al supra. As a result, a patient cannot put and fix the protective covering without the assistance of another hand or anotherindividual. Several wraps, now available, require two hands to fix and secure the wrapping. Therefore, help may be necessary by another party in the event the harm is in an arm or hand, especially if the covering needs to be held with one hand andtightened by the other hand.
In the past, most protective coverings for wounds have contained some kind of absorbent material, with the notion that wicking from bodily fluids assists in healing. But, there’s considerable literature to indicate that a drying environment mayslow healing time and also increase scar tissue formation due to compelling the migration of epidermal cells under a scab that has shaped in a dry atmosphere.
Accordingly, there’s a need for protective wraps that are constructed of flexible, liquid impermeable substances, self-applying with one hand and giving a watertight barrier for bathing without causing restriction of blood flow into the site ofinjury over extended periods of use.
