Definitions

  • This invention relates generally to bandages and related methods for use in severe cases of trauma and particularly to a bandaging system used to treat wounds to control severe bleeding and to treat burns, removing excess heat and controlling fluid loss.
  • bandages in use by physicians and paramedic personnel to control and manage external bleeding from serious wounds, lacerations and burn injuries.
  • These typically comprise tourniquets, field dressings, and absorbent bandages.
  • the dressings are absorbent and readily become saturated with shed blood, thereby sharply reducing their usefulness and thus becoming a source of infection and contamination.
  • Tourniquets are dangerous in emergency situations even when used by well trained physicians and technicians because application of the tourniquet requires severely restricting blood circulation between the heart and the injury in order to stem the flow of blood from the wound. If improperly applied or attended, the tourniquet application can cause acute toxicity in the patient resulting in loss of life or limb. In practice, treating serious lacerations and wounds is difficult even under hospital conditions, and the currently used tourniquet, bandages and dressings for field treatment are often inadequate.
  • this novel invention comprises a bandaging system which overcomes or alleviates known problems related to treatment of wounds or burns, especially in field and surgery environments, which system provides the following advantgage ⁇ : an inflatable bladder contained in an expandable and distensible housing which is facilely attached to a patient with flexible, stretchable straps and a bladder inflation system whereby controlled pressure is applied to an injury while maintaining critical blood circulation to a distal extremity; adjustable orientation of the housing relative to positioning of the straps to provide conformable application of the bandage over the injury; specially treated injury contacting and covering material releasibly affixed to the patient side of the housing which provides a medicating agent which accellerates clotting to aid in the reduction of bleeding, an antiseptic agent to reduce infection, and an anesthetic agent to reduce pain; thermal insulation characteristics which permit the temperature of the wound to rise to near body temperature to aid blood clotting; and use of the bladder inflating system for local
  • a principal object of the present invention is the provision of novel bandage structure, and related method, which overcomes or alleviates problems of the prior art.
  • It is a principal object to provide a bandage system comprising an inflated bladder compressively applied to an injury site by which fluid flow from the injury is suppressed without cutting off blood supply to parts distal from the injury site.
  • the contact surface comprises antihemorrhagic agents to hasten blood clotting, anesthetic agents to reduce injury related pain, and antiseptic agents to retard infection.

  • Figure 2 is a drawing showing an attached and secured bandage comprising a deflated bladder with a top accessible valve stem and a gas cylinder bladder inflating device in position to inflate the bladder.
  • Figure 3 is a drawing showing the bandage of Figure 2 comprising a filled bladder.
  • Figure 4 is a drawing demonstrating the separability of a surface contacting interface layer, which interfaces between the bandage bladder and the injury, releasing from adhesion to the bladder and remaining affixed to the injury site as the bandage is removed.

  • bladder bandage 20 In addition to pressure and closure brought about by initially securing bladder bandage 20 about the wound, at least three other processes aid in bringing bleeding under control. Massive bleeding is stopped without saturation of the bandage with whole bloodm by applying necessary additional pressure on the wound side by inflating bladder 170 to increase the pressure without cutting the circulation, thereby affording the benefits of the tourniquet without the negative aspects of tourniquet application.
  • wound produced fluid containment by bladder bandage 20 comprises directed pressure to the wound site to suppress bleeding and materials configured to contain rather than absorb shed blood.

  • Fluid loss in the case of burns is also critical. However, fluid loss in the case of burns is substantially due to "weeping" of the tissue, the permeability of which has been affected by burn trauma. Loss of fluid from plasma "weeping” can cause shock and death if not properly managed and can cause irreparable skin damage to the victim due to fluid loss in the tissues.

  • Inflation needle 40 associated with control valve 30 is removed from valve stem 140 and bladder deflation apparatus 60 is employed to reduce the pressure in over-inflated bladder 170. If the pressure in bladder 170 requires readjustment for reasons comprising changes in tissue permeability, seepage or other injury caused fluid flow, and discovered anoxia in distal tissue, the inflation/deflation steps previously described are repeated as necessary.
  • the in-use pressure inflation/deflation apparatus is removed from valve stem 140 attachment and set aside, as shown in Figure 3.
  • bladder bandage 20 is partably removed from the injury.
  • strap 130 is unhooked and ends separated, releasing bandage 20 from pressure contact against the injury.
  • Strap 130, bladder housing 110, and ridge member 290 are separated from surface contact layer 120 and set aside for disposal.
  • Surface contact layer 120 is removed from the reticulum of the wound as part of related surgical procedures. All of the parts of bandaging system 100 are disposable using accepted human waste and medical instrument disposal procedures.
  • bandaging system 100 comprises a special galeiform housing to apply pressure to a laceration with appropriate fluid control connections and head attachments to provide a pressure bandage to a skull area.
  • bandaging system 100 comprises galeiform housing 198 as seen in a side view in Figure 10 and a rear view in Figure 11, inflatable bandage 20 comprising a remote valve stem 140, and fluid delivery tubing 182.
  • Galeiform housing 198 further comprises a skull covering helmet 180 comprising mounting hole 188 for valve stem 140, chin straps 184 and dorsal neck straps 186.
  • valve stem 140 is disposed away from bandage 20, mounted in a fixed position 188 in helmet 180 and ⁇ xt ⁇ n ⁇ ibly connected to bandage 20 through extension tubing 182 allowing bandage 20 to be variously positioned across a headwound.
  • Helmet is made from compilable, nonelastic resinous synthetic material or other material which maintains a compre ⁇ ive relationship against an expanding bladder residing between helmet 180 and patient head 162.
  • inflatable bladder bandage 20 is laid along the laceration such that ridge 190 lies directly over the wound.
  • Galeiform housing 198 is placed over patient head 162 to hold bladder bandage 20 in place.
  • Adjustable chin straps 184 are releasibly tightened as are dorsal neck straps 186 with hooks 134 and loops 132 to firmly secure galeiform housing 198 to patient head 162.
  • Inflation needle 40 first connected into previously prepared pressure delivery apparatus 80 is inserted into valve stem 140 which protrudes accessibly through valve stem exit portal 188 in galeiform housing 198 and communicates with bladder 170 through valve stem extension tubing 182.
  • Gas cylinder 10 is turned counter-clockwise in control valve 30 to inflate bladder 170 and apply pressure to the wound.
  • the initial injury cooling contact from gas expanding into bladder 170 initiates immediate vascular spasming which aids rapid blood clotting in conjunction with hemostatic contact with surface contact layer 120.
  • Insulating properties of bladder bandage 20 allow the wound site to promptly rise to body temperature which is optimum for blood clotting.
  • ready access to the injury site is provided by removal of all applied parts of galeiform housing 198 and partable removal of bandage 20 except surface contact layer 120 which is left in place over the injury site for later removal as part of the related follow-on surgical procedure.
  • Bandaging system 100 is also used in multiple emergency medical applications for injuries not specifically associated with wound or burn care. These applications comprise emergency treatment of severely sprained or broken necks, knees, ankles, elbows, backs, shoulders, and hands, plus immobilization of broken collar bones. Use in these applications is appropriate due to the efficacy of the invention and preciousness of storage space in field support transportation equipment.
  • bladder bandage 20 is used as a medical collar to immobilize the neck and upper spine by placing the bladder housing 110 directly on the affected area and securing strap 130 around the neck. Bladder 170 is then inflated to the desired pressure to hold patient head 162 securely in place and prevent neck movement which can cause severe spinal cord injuries to patients with a broken neck.
  • Figure 14 shows the position of bladder bandage 20 used in a case of a broken collar bone.
  • Bladder housing 110 is placed directly between the shoulder blades and flexible holding straps 130 wrapped in a figure eight under the armpits and around the shoulders and secured before inflating bladder 170 to a desired pressure, thereby holding the upper body in the most favorable position for a patient with a collar bone break or shoulder separation.
  • a broken, or sprained, hand or finger injury is treated effectively by placing bladder housing 110 on the palm area of a hand 164 and securing flexible strap 130 around hand 164. As shown in Figure 12, inflated bladder 170 creates a firm convex support to immobilize the hand and fingers. In all cases, applications of bladder bandage 20 provides pressure to an injury without impairing patient circulation.
  • bladder 170, bladder housing 110, and straps 130 are variously configured to meet needs of the many different types and sizes of injuries treatable by bandaging system 100.
  • the invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof.
  • the present embodiment is therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.

Abstract

Nouveau système de bandage destiné à être utilisé dans les cas de lacérations graves, en chirurgie, pour les brûlures et les blessures sans lésions. L'invention élimine les désavantages de garrots, les pansements de terrain, ainsi que les bandages absorbants, assurant un refroidissement et une pression initiale sur le site des lésions, une compression et une contraction de la lésion, le maintien d'une température optimale de coagulation, le maintien de la circulation sanguine, une protection contre la contamination, et elle permet l'application d'agents anti-hémorragiques, anesthésiants et antiseptiques sur le site des lésions dans un bandage biomédical jetable. Le système de bandage comprenant une vessie gonflable (20) ainsi qu'un appareil d'application de pression (80) est totalement indépendant et il empêche la perte de liquides biologiques tout en améliorant le temps de coagulation du sang et permettant le remplissage par apport de sang des parties corporelles distales par rapport au c÷ur, au-delà d'une blessure existante.
