Definitions

  • the wound opening creates a path for outside air to flow into the chest cavity.
  • This flow of external atmospheric air into the chest cavity eliminates the negative pressure which normally exists in the pleural space.
  • the lungs cannot inflate properly, because the chest defect allows the air which has been drawn into the chest cavity to equalize the pressure therein with the atmospheric pres ⁇ sure.
  • the presence of the atmospheric air in the chest may also introduce contaminates into the chest cavity.
  • one of the treatment procedures is to provide an occlusive dressing large enough to overlap the wounds' edges and taped securely on all four sides so as to seal the wound and prevent air from passing into the chest cavity through the wound. This permits the patient to breath without building up pres ⁇ sure within the cavity unless the lung has been punc- tured or torn. If the lung has been penetrated, air will be drawn into the chest cavity through that pene ⁇ tration and produce a pressure build-up within the chest cavity if the wound has been sealed externally .
  • the American College of Sur- geons recommends the taping of the occlusive dressing on only three sides so that if pressure is building up within the chest cavity, this pressure may be discharged through the open side of the dressing.
  • the conditions surrounding the emergency treatment of the patient may neutralize the valve effect of this type of dressing application. These conditions include the application of a spine board, other pressure dressings, cot-restraint belts and the specific location of the wounds relative to the patient's position during transport. Frequently, the patient also will have to be moved into a position, or external restraining or sup ⁇ port apparatus applied to the patient will interfere with the operation of the valve effect of the open side of the dressing.
  • This invention provides a valve controlled release opening to prevent this pressure build up in the chest cavity.
  • This invention provides a one-way control valve for emergency adhesive application to the chest of a patient having a wound opening which has penetrated the chest wall. The one-way valve permits air and liquid to pass outwardly from the cavity but closes the same against the flow of atmospheric air into the chest cavity.
  • this pressure prevents the creation of a life threatening condition within the chest cavity by maintaining a sub-atmospheric condi- tion within the cavity required for lung inflation.
  • this device may be used during pressur ⁇ ized mechanical ventilation without adding to the risk of a tension pneumothorax. Normally, a negative pres ⁇ sure exists within the chest cavity. Imposing a posi- tive pressure within the cavity creates an immediate life threatening condition that must be corrected as soon as possible.
  • This invention provides a flexible pressure sensi ⁇ tive adhesive attachment panel for attaching the re- lease valve over the penetrating wound to prevent pres ⁇ sure build up in the chest cavity.
  • Fig. 1 is a view showing the chest cavity with the basic anatomical components housed therein;
  • Fig. 2 is a top plan view of a check valve assem ⁇ bly embodying the invention
  • Fig. 3 is a vertical sectional view through the check valve assembly and taken substantially along the line 3-3 of Fig. 2; and.
  • Fig. 4 is an exploded perspective view of the check valve assembly.
  • FIG. 1 illustrates a valve assembly embodying the invention.
  • This valve includes a rigid annular base member 10 which is permanently secured a flexible attachment member 11, which in the form shown consists in a panel or sheet made from suitable transparent flexible plastic material having a transparent pressure sensitive adhesive coating 12 on the bottom surface thereof.
  • the flexible attachment panel 11 must be suffici- ently large and have sufficient stiffness to prevent it from being drawn into a penetrating thoracic wound. Flexibility is important to permit the panel to conform to the irregularities of the outer surface of the pati ⁇ ent's chest.
  • the panel should also be transparent, so that the valve can be visually positioned with its base surrounding the outside of the wound to sealingly en ⁇ close the same.
  • a number of different clear plastic films are suitable such as are manufactured by Molco, of Waymart, Penna.
  • the wound 15 is shown diagramatically in Fig. 3 with the surrounding skin layer designated by the num ⁇ eral 16.
  • the adhesive must, of course, be hypo-aller- genic, be resistant to the presence of blood, moisture, and other body fluids, and remain active under temper- ature variations encountered at the scene of the in ⁇ jury. Furthermore, the adhesive should also permit removal of the panel and valve assembly without leaving significant amounts of adhesive residue on the pati ⁇ ent's skin surface.
  • a suitable adhesive is manufac- tured by 3-M Company of St. Paul, Minn. , and is used on their 3-M Stoma Seal 1500 product.
  • the base 10 is made from suitable rigid trans ⁇ parent material such as a suitable rigid plastic mater ⁇ ial and has a valve housing 20 fixed thereon in spaced relation thereabove.
  • the housing 20 is dome shaped with spaced cut out openings 21 which form support struts 20a around the periphery thereof.
  • the spaced struts 20a are connected in fixed relation to the annular base member 10 and support the housing dome 20 on the annular base 10.
  • the openings 21 around the top of the base 10 permit air, blood, and body fluids to escape through the wound opening 15.
  • a valve element 25 is made from highly flexible thin material such as latex or vinyl and in the form shown is generally circular in shape with its center attached to the center of a supporting spider frame 10a as by a post or rivet 25a.
  • the spider frame 10a is fixed across the opening defined by the annular base member 10.
  • the valve disc 25 is connected at its center to the center of spokes 10b to the sup- porting spider frame 10a to maintain the valve disc 25 in alignment with its annular valve seat 10c extending around the inside of the lower portion of the central opening defined within the annular base member 10.
  • the valve element 25 is shown in closed seated position in Fig. 4.
  • valve disc In its closed position, the valve disc seals against the planar annular seat 10c with intermediate support being provided by the spokes 10b of the frame 10a. Openings lOd defined between the spokes 10b per ⁇ mit air and fluids to pass out from the chest cavity to prevent pressure from building up with the cavity.
  • the dome 20 protects the valve against contact from objects that would interfere with its opening and closing action.
