  • Patent number: 12285350
    Abstract: A medical splint securing system and method particularly suited for emergency medical care applications is disclosed. The system comprises three elongated fabric strips, each preferably measuring 5½ inches by 100 inches, permanently joined at their respective midpoints to form a unified structure with a central junction preferably measuring 5½ inches by 50 inches. This quick tie system simplifies and expedites the process of securing blanket roll splints in emergency situations, replacing traditional multiple-cravat methods. The unified design ensures adequate length for secure attachment while maintaining professional appearance during application. The system's versatility extends to use in sling and swathe immobilization techniques. The invention addresses key deficiencies in conventional splinting methods, including time consumption and inadequate securing length, while providing a more efficient and reliable solution for emergency medical responders.

  • Patent number: 12220341
    Abstract: A pressure system and method for managing post-operative swelling. The pressure system has a balloon with a quadrilateral basal skirt that surrounds a surgical site on a patient. A plurality of strap-receiving slots is located in the skirt. Adhesive pads are affixed to the patient outside the skirt. One or more tensioning straps are deployed between the strap-receiving slots and the adhesive pads so that tension can be applied to the straps and to the skirt in order to press the balloon upon the surgical site. Optionally, the pressure system provides visual feedback cues to enable the operator to determine appropriate compression and assess skin recoil feedback. Such visual feedback cues may signify swelling reduction and skin turgor.

The auxiliary strap is secured to the wrap and is normally held in stowed position on the wrap, but arranged to be moved to an extended position whereupon the secondary absorbent bodies overlies said primary absorbent body and apply pressure thereto and to the underlying aggressive bleeding site.

  • Patent number: 10010656
    Abstract: A reduced pressure dressing for applying reduced pressure treatment to a tissue site includes an interface layer adapted to be positioned at the tissue site. An absorbent layer is in fluid communication with the interface layer to absorb liquid from at least one of the interface layer and the tissue site. A pump is in fluid communication with the absorbent layer to deliver a reduced pressure to the tissue site. A cover is positioned over the pump, the absorbent layer, and the interface layer to maintain the reduced pressure at the tissue site, and a liquid-air separator is positioned between the absorbent layer and the pump to inhibit liquid from entering the pump.

  • Patent number: 9660301
    Abstract: An electronic apparatus is provided. The electronic apparatus includes: a battery; at least one pressure sensor provided on a surface of the battery; and a controller electrically connected with the at least one pressure sensor. The at least one pressure sensor samples a pressure parameter on the surface of the battery. The controller acquires the pressure parameter, detects a magnitude relation between the pressure parameter and a predefined threshold value, and generates a control instruction for protecting the battery based on the detected magnitude relation.

  • Patent number: 9649226
    Abstract: The devices, kits and methods described may be used for wound healing, including the treatment, amelioration, or prevention of scars and/or keloids by applying and/or maintaining a pre-determined strain in an elastic skin treatment device that is then affixed to the skin surface using skin adhesives to transfer a generally planar force from the bandage to the skin surface. Applicators are used to apply and/or maintain the strains, and some of the applicators are further configured to provide at least some mechanical advantage to the user when exerting loads onto the skin treatment device.

  • Patent number: 9629986
    Abstract: The composite wound dressing apparatus promotes healing of a wound via the use of a vacuum pump. The vacuum pump applies a vacuum pressure to the wound to effectively draw wound fluid or exudate away from the wound bed. The vacuum pump is tethered to the wound dressing and is portable, preferably, carried by the patient in a support bag, which permits patient mobility. Moreover, the patient does not need to be constrained for any period of time while exudate is being removed from the wound.

  • Patent number: 9610390
    Abstract: The present invention relates to apparatuses and methods for treating a wound by applying reduced or negative pressure to the wound. The apparatus can include a wound cover, a fluid collection container, a vacuum pump, an inflation pump, and one or more conduits. The wound cover can be configured to move between at least a relatively rigid, generally raised position and a relatively flexible, generally collapsed position according to a predetermined program or in response to input from a user or one or more sensors. In some embodiments, the wound cover can be configured to move between at least the relatively rigid, generally raised position and the relatively flexible, generally collapsed position by adjusting the air pressure in one or more channels in the wound cover or by adjusting the length of piezoelectric or other length changing material supported by the wound cover.

  • Patent number: 9439827
    Abstract: Tissue compression devices having pressure indicators and methods of using the same. The tissue compression devices provide feedback to a user with respect to the pressure being applied to selected tissue at a selected location such as a radial artery to assist the user in applying the desired amount of pressure to the tissue (such as the pressure needed to achieve hemostasis at an access site). The pressure indication may be provided by a ring indicator that moves between two configurations (e.g., a concave configuration and a convex configuration), a bellow chamber in a housing, a bladder located below a bladder window, etc.

  • Patent number: 9414837
    Abstract: Suture clip deployment devices for applying suture clips to sutures are described. Some embodiments can include a generally tubular main body and a vacuum port located at the distal end, a hollow inner body longitudinally slidable within the main body and extending from the main body at its distal end, and a suture recess located in the generally tubular main body. At least one suture clip configured to frictionally fit on an outer surface of the inner body is deployed during use. Clip deployment can occur after a vacuum source is applied to the device so as to draw the suture into the device. The suture lines can be retrieved through the suture recess, and the device can be actuated so as to deliver the suture clip off the delivery device and onto the suture, locking the suture in place.

  • Patent number: 9198803
    Abstract: A dressing device has a device body, a bore extending into an inner surface of the device body, and a biasing element positioned within the bore for biasing the dressing element against the ulcer. The device body functions to offload pressure from an ulcer of a patient. The biasing element functions to support a dressing element against the ulcer to medicate the ulcer, and to prevent the formation of proud flesh.
