H&H has made several important improvements to the overall design of this product in response to customer feedback. The improvements you will see include:
Enlarging the pull tab for easier removal of the chest seal from the backer and easier use and application.
Adding a dry edge around the exterior of the seal to reduce incidences of adhesive sticking to packaging or user’s gloves.Upgrading the hydro-gel for increased adhesion.
Repositioning of the three one-way valves into a straight line to make folding the product into kits and packs easier.
Adhering the one-way valves to the valve cover and adding a foam stabilizer to lock the valves in place and reduce the risk of air getting past the valves and into the chest.
The Bolin Chest Seal now comes packaged with a 5" x 9" ABD Trauma pad.
Sucking chest wounds require an emergency first aid solution that is fast, direct, and effective: the H&H Bolin Chest Seal™ (BCS™) is specifically engineered to meet these critical needs.
The BCS™ is a sterile occlusive chest wound dressing for treating open pneumothorax and preventing tension pneumothoraces that result from gunshots, stab wounds, or other penetrating chest trauma. The patented failure-proof triple-valve design of the BCS™ allows air and blood to escape while preventing the re-entry of either, thereby eliminating any unwanted gas or liquid exchange at the trauma site.
The Journal "Injury" did a side-by-side comparison of the Bolin vs. Asherman Chest Seals using porcine (swine) models. Both performed well, however in the presence of blood the Bolin outperformed:
"The Bolin and Asherman chest seals were equivalent in preventing the development of a tension pneumothorax in this open pneumothorax model. However, the Bolin chest seal demonstrated stronger adherence in blood soiled conditions."

The military has been tinkering with the standards of care for Combat Lifesavers. Currently they are moving away from totally occlusive chest seals and using vented chest seals such as the Bolin along with improved adhesive. A bit more bulk but well worth it is improved perfomance.
Most Chest Valves are best packed flat. This makes them hard to pack in small kits. The newer Bolin folds fairly well, so packs easier. 3 valves give a bit of an easier unit to place.
