Abstract:
A training apparatus (10) for the practice of puncturing blood vessels, said apparatus comprising a model arm and an air-tight, liquid-tight compressible liquid container (19) and means for transferring liquid between the container and the model arm, which model arm comprises a core (14) of a solid material, a tight-fitting cover (32) of a penetrable material and at least one penetrable tube (31) provided between the core (14) and the cover (32), one end of said tube being connected to the liquid container (19) and the other end being sealed, wherein the said liquid container (19) is integrated into the model arm and disposed in such a manner so as to allow it to be compressed by establishing a pressure on a part of the surface of the model arm.
Abstract:
A method for performing cardiopulmonary resuscitation employs an applicator device having a body with an upper surface and a lower surface. The lower surface includes provisions for detachably securing to the patient's chest, such as a vacuum cup or an adhesive layer. For manual resuscitation, the upper surface will include a strap or other means for securing a performer's hand thereto. In an exemplary device, a disc-shaped handle (204) is attached to the upper surface of a vacuum cup applicator (202) by a short connecting stem structure (206). A pressure gauge (224) may be mounted in the handle structure (204), providing a positive and negative for scale to permit the user to monitor the force being applied. For automatic applications, a mechanical drive member will be secured to the upper surface. By alternately pressing and lifting on the applicator device, the patient's chest can be compressed and expanded to improve induced ventilation and circulation.
