Intended Use

The intended use of the Cuff Saver will be to cover all types of blood pressure cuffs and/or cuff bladders prior to the cuff or cuff bladder being applied to the patient. This will protect the patient and the health care worker from overt and covert exposure to soiled or contaminated blood pressure cuffs.

Device Story

Camouflage Cuff Saver is a disposable, non-woven paper drape designed to cover reusable blood pressure cuffs or function as a disposable cuff when paired with an inflation bladder. Device is manufactured from fluid-repellent Sontara non-woven fabric with 3M double-sided adhesive tape for securement. Used in clinical settings (hospitals, surgical suites, recovery rooms) by healthcare workers to mitigate infection risks associated with contaminated reusable cuffs. Device is applied to the patient's arm; the cuff or bladder is placed atop it and secured. After use, the device is discarded, preventing pathogen transmission between patients. Benefits include reduced nosocomial infection rates, protection of reusable cuffs from soiling, and cost-effective infection control. Device does not interfere with blood pressure measurement performance.

Clinical Evidence

Clinical testing performed on 17 human volunteers of varying sizes. Study compared blood pressure measurements taken with standard reusable/disposable cuffs versus those covered by the Camouflage Cuff Saver, and the Cuff Saver used with an inflation bladder. Measurements were validated against a calibrated mercury sphygmomanometer using a Dinamap noninvasive blood pressure monitor. Results showed no appreciable difference in blood pressure readings between test and control groups. All measurements met protocol acceptance limits (95% CI of 4.3 or less). A small culture study in an operating room showed 0 colony growth on protected cuffs versus bacterial growth on unprotected cuffs.

Technological Characteristics

Material: DuPont Sontara F802 nonwoven fiber (55% polyester, 45% wood pulp). Fastening: 3M No. 9890 double-coated medical tape. Form factor: Perforated roll of non-woven drapes. Function: Fluid-repellent substrate for cuff protection or bladder containment. Biocompatibility: Materials are industry-standard and biocompatible. No electronic components; purely mechanical/physical barrier.

Indications for Use

Indicated for use as a protective cover for blood pressure cuffs or as a disposable component for cuff bladders in all patient populations to prevent cross-contamination and exposure to pathogens.

Regulatory Classification

10-4

Identification of the Equivalent Device:

We compare the Cuff Saver, which is essentially a paper drape, to two (2) known disposable blood pressure cuffs (Vital Signs Clean Cuff K912638 and Criticon Disposables [no K number]. Both of these are vinyl/latex composition and are labeled in print by the manufacturer for single patient use. We also compare our device to Bowen Medical Cuff Guard K952825. Our device is less costly than our competitors (< $1.00 vs. > $5.00). As we understand the classification system, these vinyl/latex cuffs and cuff covers considered Class 2. We also have identified Patent Number 5,228,448 for a protective cover for blood pressure cuffs. The above identified cover is designed to be placed about the patient's arm and the blood pressure cuff is then placed atop the cover. The cover is folded over the cuff at that time. It is constructed of a two-ply fabric with one layer being absorbent and the other fluid repellent. The construction and application of this device make it complicated to manufacturer and time consuming to use. At this time, we do not know of

anyone offering this device for sale in the medical industry. Our product is manufactured of fluid repellent medical grade Sontara non woven fabric. Camouflage Cuff Savers may also be used as the cuff itself when paired with the commercially available cuff inflation bag/bladder and, as such, serves to function as the disposable member of the blood pressure cuff in addition to it's role as a protective cover for reusable cuffs. The non woven fabric is a strong, fluid repellent substrate and the double sided adhesive tape used forms a strong secure bond when applied to the material. This allows the Cuff Saver to cover a cuff Bladder and thus become a reliable blood pressure cuff for single patient use.

## Description of the Device:

The Camouflage Cuff Saver is essentially a non woven paper drape that can cover/contain a normal blood pressure cuff, a disposable cuff, or a cuff bladder. It is fluid repellent and acts to ensure a clean cuff for each patient as it is discarded after single patient use. It is manufactured of medical grade Sontara non woven fiber with 3M brand double sided adhesive tape as a fastening along one vertical edge of the unit and an adhesive patch located on the printed side of the unit. This patch is used to secure the device to its own surface after the device and the cuff it covers are applied to the patient's arm. As stated, the device is printed with a design and typical marking for a blood pressure cuff (Artery placement, Range line, etc.). It is available on a perforated roll so that the user can tear off one unit at a time just as one removes a paper towel from its roll.

It has been the concern of many health care workers that the blood pressure cuff is a potential source of contamination in the hospital environment. Reusable cuffs are difficult, it not impossible to clean and, more often than not, are never cleaned. "Single use Only" cuffs are used until they deteriorate and are also poorly cleaned. Blood pressure cuffs used in the surgical suite remain on the patient when the patient is transported to the ICU or recovery room. This represents a poor understanding of infection control standards. The Cuff Saver attempts to address these problems by providing a clean, cost effective alternative to the current market.

Cuff Savers do not interfere with the performance of the functional cuff that it serves to cover and may also be used as the cuff itself when used to cover a cuff bladder. The Cuff Saver is soft, clean, covers the blood pressure cuff, and after use, is discarded. This prevents contaminated cuffs from being transmitted with their contaminants to the recovery or critical care areas of the hospital.

Intended Use of the Device:

The general intended use of the Cuff Saver will be to cover all blood pressure cuffs prior to being applied to the patient. As stated earlier, it can also cover a cuff bladder and be used as the cuff itself. When used as a cover or disposable blood pressure cuff, this will keep the patient from being exposed to a dirty cuff and will also protect the health care worker from overt and covert exposure. The device will also serve to protect the reusable cuff from soiling and thus prolong the life of the reusable cuff.

The entire general patient population will be impacted with the use of the Cuff Saver. Health care workers will be impacted as well. Dirty blood pressure cuffs should no longer be a problem as, once cleaned, the Cuff Saver will protect blood pressure cuffs and cuff bladders from further contamination. By using the Cuff Saver in combination with the inflation bladder as the cuff, cleanliness can be assured because the Cuff Saver can be discarded and the bladder can be easily cleaned due to it's non porous surface. The older unsanitary reusable cuffs that employ Velcro as their fastenings are impossible to clean and retain all sorts of surface material and contaminates. Cuff Savers do not use Velcro as a fastening. Instead, a very strong double sided adhesive tape is used to attach the cuff surfaces to each other. No adhesive is in contact with the patient's skin.

Since it has been shown in the current medical literature that standard blood pressure cuffs harbor pathogens, it follows that the Camouflage Cuff Saver should and will be of great benefit in protecting the patient and the health care worker from pathogens. It should also be of use in the prevention of transference of disease and nosocomial infection. In light of these potential health benefits to the general public, we request that Camouflage Cuff Savers be considered for Expedited Review.

Determination of Substantial Equivalence and Testing Summary:

Basically, the Camouflage Cuff Saver is a disposable blood pressure cuff designed to be used in conjunction with a reusable cuff or commercially available inflation bag/bladder. When applied to the reusable cuff, it does not alter the performance of said cuff, yet it protects the cuff from contamination and soiling. When used with the inflation bladder, it functions as a disposable cuff itself and performs as well as a standard cuff. Clinical tests performed by N. A. Braggs Medical, Inc. on seventeen human volunteers of various sizes and upper arm circumference provide credible proof. Tests were performed with standard sizes of commercially available blood pressure cuffs of both the reusable and disposable varieties. Cuffs of the bladder type and the bladderless

type were tested with and without the application of the Camouflage Cuff Saver device. The Cuff Saver was also tested with the standard commercially available inflation bladder with the Cuff Saver covering the bladder and the Cuff Saver acting as the Cuff itself. Each subject's pressure was taken in the order listed with a three minute waiting period between each measurement. The pressures were taken using a Dinamap Brand noninvasive blood pressure machine. Measurement accuracy was confirmed by checking the Dinamap machine against pressure taken with a calibrated mercury sphygmomanometer. For accuracy, cuffs used on each volunteer were at least 40% as wide as the circumference of the subjects upper arm. All subjects were awake and in an unaltered state of awareness during the testing.

The finding of the testing process showed no discernible or appreciable difference between the blood pressures taken with the conventional blood pressure cuffs and those fitted with the Camouflage Cuff Saver device. There was also no appreciable or discernible difference between the blood pressures taken with the conventional cuff and those taken with the Camouflage Cuff Saver fitted with the standard inflation bladder. All of the measurements obtained conformed to the data acceptance limits set forth in the testing protocol and all results conformed to the pass/fail criteria of a 95% Confidence interval of 4.3 or less derived from data collected from measurement of blood pressure taken with the calibrated Dinamap brand blood pressure machine and the two industry standard cuffs used in the study. Minor fluctuations in the results obtained are attributed to the dynamic state of blood flow within the cardiovascular system and are physiologic in nature. In conclusion, Camouflage Cuff Savers offer the public a functional, inexpensive alternative to the current disposables on the market today and provide a public health benefit to the general population by reducing the incidence of cross-contamination.

Safety and Effectiveness- Information contained in the body of the notification accompanying this summary provides biocompatibility data for the materials used in the construction of this device. Materials consist of DuPont Sontara F802 nonwoven fiber (55% polyester, 45% wood pulp), and 3M brand No. 9890 Double Coated Medical tape on a liner. Both products are biocompatible according to the test information supplied by the respective companies. Both products are already in use in the medical industry. Ink information is also supplied in the body of the notification and complies with national industry safety standards. Effectiveness of the device is confirmed by statistical analysis of data contained in the Investigational Study located in the body of this 510(k) notification. Study data indicated that the Camouflage Cuff Saver can functional safely as a blood pressure cuff or as a cuff cover. Slight variations in the readings are physiologic and represent the dynamic state of the cardiovascular system. In a study conducted by Martin G. Myers, M.D., protecting cuffs during patient contact resulted in a marked and rapid decrease in the infection rate.(1) Reinforcing this literature is the small culture study performed in a working operating room by this company. In our study, the cuff that was protected with our device during patient contact produced "no growth 48 hrs" and a 0 colony count. This was not the case with the unprotected cuffs which all grew bacteria. The world wide web was thoroughly searched for information pertaining to national or international standards for blood pressure cuffs. Apparently none exist. The F.D.A. has no performance standards for blood pressure cuffs. The American Heart Association was contacted for information pertaining to cuff standards. There were no direct standards. Their recommendations for accuracy include monthly calibration of manual home spygmomanometer units against an ancriod or mercury spygmomanometer and use of the correct size cuff to limb ratio (the cuff should be at least 40% as wide as the circumference of the limb to which it is applied). The Camouflage Cuff Saver complies with these AHA recommendations.
