Project TitleCuff for Sealing the Joints of Personal Protective Suits
Track Code2017-045
Short Description

A novel cuff for sealing the joints of personal protective suits.

Abstract

This invention provides an exterior protective cuff that applies in seconds, creating an effective sanitary seal for hazardous environments. This new cuff device is also affordable and disposable.  One of the most notable features of this device is its ability to be used in situations where the worker’s dexterity is imperative, as it does not restrict the user’s critical hand and feet movement.  Unlike current solutions on the market today, this device does not require any assistance to apply, and creates an effective seal even if implemented in a hasty manner.

Background

Personal Protective Equipment, or PPE, is a basic and extremely necessary aspect of any job in the health, manufacturing, mining, food, and many other industries.  Each industry has a high standard of the types of clothing and protective devices that can be used, since workers’ lives can be severely impacted by certain hazardous environments.  Many times throughout hazardous jobs, dangerous environments with high concentrations of toxic substances become present, and workers must suit up in personal protective suit very quickly. This situation is especially prevalent with emergency medical responders and other workers who may encounter hazardous chemical and biological exposure situations.  Thanks to protective suits, toxic substances are not able to make contact with the worker’s skin. There are, however, instances where extraordinary means of PPE is required, especially instances where typical suits do not provide an airtight seal to block out the smallest of toxic particles. 

An airtight seal may be necessary to protect users from hazardous materials entering the protective suit through gaps in the intersections of multiple articles of protective clothing (i.e. the area between a glove and a sleeve). There are options a worker can take to more thoroughly protect themselves from hazardous materials breaching his/her suit, but unfortunately, the only available options today are expensive, cumbersome, or take too long to apply.  Some remedies to the issue of the open area between a glove and sleeve include applying duct tape to the junction of the sleeves and protective gloves.  This method is a cheap alternative to more expensive cuff seals, but it requires a lot of time to apply, which is bad for emergency situations, it is not safe for use with hazardous materials, and it can be restrictive and uncomfortable, potentially hindering a medical responder’s ability to perform tasks requiring dexterity.  Other solutions to creating an air tight seal for protective suits involve high end suits which are not practical for every scenario, require time and assistance to apply, and can be very expensive.  Workers in various industries often site poor dexterity, long preparation times, and lack of versatility as some reasons for needing new, innovative methods of sealing open junctions in protective outfits.

Technology Description

Researchers at the University of New Mexico have developed a novel cuff for sealing the joints of personal protective suits.  This invention provides an exterior protective cuff that applies in seconds, creating an effective sanitary seal for hazardous environments. This new cuff device is also affordable and disposable.  One of the most notable features of this device is its ability to be used in situations where the worker’s dexterity is imperative, as it does not restrict the user’s critical hand and feet movement.  Unlike current solutions on the market today, this device does not require any assistance to apply, and creates an effective seal even if implemented in a hasty manner.

Advantages/Applications

  • Cuff is capable of being easily positioned over the sleeve and glove junction, allowing the final fit to be adjusted as desired
  • Creates a tight and secure seal to prevent exposure to external contamination
  • Much faster and easier to use than current PPE suits
  • Affordable, sanitary and disposable
  • Universal – can be used with various types of protective suits, gloves, etc.
