ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a medical sanitation system and more particularly pertains to a disposable cover removably secured to a blood pressure cuff capable of protecting the cuff from becoming contaminated and/or contaminating the patient.
2. Description of the Prior Art
The use of disposable covers for blood pressure cuffs is known in the prior art. More specifically, disposable covers of know designs and configurations previously devised and utilized for the purpose of protecting cuffs from becoming contaminated are known to consist basically of familiar, expected, and obvious structural configurations, notwithstanding the myriad of designs encompassed by the crowded prior art which has been developed for the fulfillment of countless objectives and requirements.
By way of example, U.S. Pat. No. 5,228,448 to Byrd discloses a protective cover for a blood pressure cuff. U.S. Pat. No. 5,513,643 to Suite discloses a disposable protection wrap for use with a sphygmomanometer. Lastly, U.S. Pat. No. 5,620,002 to Byre et al discloses a universal blood pressure cuff cover.
While these devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not describe a medical sanitation system that allows a disposable cover to be removably secured to a blood pressure cuff and for protecting the cuff from being contaminated or from contaminating the patient.
In this respect, the medical sanitation system according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in doing so provides an apparatus primarily developed for the purpose of providing a disposable cover to be removably secured to a blood pressure cuff and for protecting the cuff from being contaminated or from contaminating the patient.
Therefore, it can be appreciated that there exists a continuing need for a new and improved medical sanitation system which can be used for protecting the cuff from removably securing a disposable liner to a blood pressure cuff and for protecting the cuff from becoming contaminated or from contaminating the patient. In this regard, the present invention substantially fulfills this need.
SUMMARY OF THE INVENTION
In view of the foregoing disadvantages inherent in the known types of disposable covers of known designs and configurations now present in the prior art, the present invention provides an improved medical sanitation system. As such, the general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new and improved medical sanitation system and method which has all the advantages of the prior art and none of the disadvantages.
To attain this, the present invention essentially comprises a blood pressure cuff adapted to be wrapped around the arm of a person. The blood pressure cuff is formed of an elongated flexible strap in a rectangular configuration. The strap has long parallel upper and lower edges about 20½ inches in length and short parallel end edges about 5¾ inches in height. The strap has first and second ends so that the two ends overlap during operation and use. The strap is constituted by an interior layer of air impervious plastic material with an interior face and an exterior layer of air impervious elastomeric material with an exterior face. Defined within the interior layer and the exterior layer is a hollow internal compartment constituting an inflatable bladder. A first connector tube is provided and extends from the bladder for connecting to a manually operated air supply pump. A second connector tube is provided for connecting to a sphygmomanometer. A single use protective liner is provided. The liner is formed in a rectangular configuration with long parallel upper and lower edges about 18 inches in length and with short parallel end edges about 6 inches in height. The liner prevents body fluids from contacting and contaminating the strap between uses on successive patients. The liner is formed of a first layer of absorbent material, a middle layer of plastic material, and a hook shaped fastening layer to secure the liner to the interior face of the strap. The liner has a height greater than the height of the cuff for extending beyond the cuff when coupled to the cuff. A fastener assembly is next provided. The fastener assembly includes a square shaped hook fastening portion about 4 inches square secured at the exterior face of the strap adjacent to the second end of the cuff. The fastener assembly also include a loop fastening portion applied to the entire area of the interior face of the cuff. The loop fastening portion extends beyond the first end of the cuff by about 2 inches for coupling with the square shaped fastening portion. Lastly, a protective envelope is provided for the cover to ensure sanitation prior to use.
There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof that follows may be better understood and in order that the present contribution to the art may be better appreciated. There are, of course, additional features of the invention that will be described hereinafter and which will form the subject matter of the claims attached.
In this respect, before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not limited in its application to the details of construction and to the arrangements of the components set forth in the following description or illustrated in the drawings. The invention is capable of other embodiments and of being practiced and carried out in various ways. Also, it is to be understood that the phraseology and terminology employed herein are for the purpose of descriptions and should not be regarded as limiting.
As such, those skilled in the art will appreciate that the conception, upon which this disclosure is based, may readily be utilized as a basis for the designing of other structures, methods and systems for carrying out the several purposes of the present invention. It is important, therefore, that the claims be regarded as including such equivalent constructions insofar as they do not depart from the spirit and scope of the present invention.
It is therefore an object of the present invention to provide a new and improved medical sanitation system which has all of the advantages of the prior art disposable covers of known designs and configurations and none of the disadvantages.
It is another object of the present invention to provide a new and improved medical sanitation system which may be easily and efficiently manufactured and marketed.
It is further object of the present invention to provide a new and improved medical sanitation system which is of durable and reliable constructions.
An even further object of the present invention is to provide a new and improved medical sanitation system which is susceptible of a low cost of manufacture with regard to both materials and labor, and which accordingly is then susceptible of low prices of sale to the consuming public, thereby making such medical sanitation system economically available to the buying public.
Even still another object of the present invention is to provide a medical sanitation system for removably securing a disposable liner to a blood pressure cuff thereby protecting the cuff from becoming contaminated and/or contaminating the next following patent after a prior use.
Lastly, it is an object of the present invention to provide a new and improved A medical sanitation system for measuring blood pressure includes a cuff to be wrapped around the limb of a person. The cuff comprises a flexible strap with first and second ends which overlap for coupling. A first layer and a second layer of material define an internal compartment forming an inflatable bladder confined within the compartment. A first connector tube connects to a manually operated air supply pump and a second connector tube connects to a sphyg
