  • Patent number: 10881854
    Abstract: Provided is a respiratory muscle strengthening device, in which an inhalation start signal is generated correspondingly at an inhalation start time when a patient inhales air or an exhalation start signal is generated correspondingly at an exhalation start time when the patient exhales air, an electric signal according to the inhalation start signal or the exhalation start signal is transmitted to an electric muscle stimulator via a communication unit, a muscle pad installed on respiratory muscles of the patient enables smooth breathing motion by stimulating the respiratory muscles based on a signal transmitted from the electric muscle stimulator, and a receptor pad is provided to the respiratory muscles such that an alarm of determining whether electric stimulation is normally applied via the state of the respiratory muscles detected through the receptor pad is output, thereby securing reliability of a device.

  • Patent number: 8372961
    Abstract: Disclosed are concatameric proteins comprising two soluble domains, in which the C-terminus of a soluble domain of a biologically active protein is linked to the N-terminus of an identical soluble domain or a distinct soluble domain of a biologically active protein. Also, the present invention discloses dimeric proteins formed by formation of intermolecular disulfide bonds at the hinge region of two monomeric proteins formed by linkage of a concatamer of two identical soluble extracellular regions of proteins involving immune response to an Fc fragment of an immunoglobulin molecule, their glycosylated proteins, DNA constructs encoding the monomeric proteins, recombinant expression plasmids containing the DNA construct, host cells transformed or transfected with the recombinant expression plasmids, and a method of preparing the dimeric proteins by culturing the host cells. Further, the present invention discloses pharmaceutical or diagnostic compositions comprising the dimeric protein or its glycosylated form.
