The invention provides a system and method for measuring vital signs (e.g. SYS, DIA, SpO2, heart rate, and respiratory rate) and motion (e.g. activity level, posture, degree of motion, and arm height) from a patient. The system features: (i) first and second sensors configured to independently generate time-dependent waveforms indicative of one or more contractile properties of the patient's heart; and (ii) at least three motion-detecting sensors positioned on the forearm, upper arm, and a body location other than the forearm or upper arm of the patient. Each motion-detecting sensor generates at least one time-dependent motion waveform indicative of motion of the location on the patient's body to which it is affixed. A processing component, typically worn on the patient's body and featuring a microprocessor, receives the time-dependent waveforms generated by the different sensors and processes them to determine: (i) a pulse transit time calculated using a time difference between features in two separate time-dependent waveforms, (ii) a blood pressure value calculated from the time difference, and (iii) a motion parameter calculated from at least one motion waveform.

The invention discloses a portable 2-DOF wrist joint rehabilitation robot comprising an arm rack to wear outside a human forearm, a hand back rack, to wear on the human back, and a 2-DOF drive mechanism connected between the arm rack and the hand back rack. The 2-DOF drive mechanism comprises a sliding mechanism, a pneumatic muscular mechanism, a rotary joint, a driving link, and a driven link; the rotary joint is driven by driving force of pneumatic muscles so that the driving link and the driven link drive the hand back rack for extension rehabilitation training of the wrist joint. The 2-DOF drive mechanism further comprises a central column, an arc rack, a cylindrical gear, and a guide rail fixed to the outside of the hand back rack. A motor drives a round gear to rotate so that the hand back rack drives the wrist to swing. The portable 2-DOF wrist joint rehabilitation robot has the advantages that the robot is portable and domesticized and gain amplification is achieved for controlling the angle of the rotary joint.

The invention discloses an elbow-joint exoskeleton robot based on lariat flexural drive, comprising a driving mechanism, upper arm front fixing mechanisms, upper arm rear fixing mechanisms, forearm front fixing mechanisms, forearm rear fixing mechanisms, elbow flexing mechanisms, an exoskeleton garment and lariats. The driving mechanism is fixed to the waist through the exoskeleton garment to provide driving power for the whole robot; the lariats are extended out of the driving mechanism, one lariat is guided by the exoskeleton garment to pass through the upper arm front fixing mechanisms andconnect to springs of the forearm fixing mechanisms, and the other lariat is guided by the exoskeleton garment to pass through the upper arm rear fixing mechanisms and connect to tension springs of the forearm rear fixing mechanisms. The elbow-joint exoskeleton robot based on lariat flexural drive has the advantages that burden of moving joints can be effectively relieved, the misalignment problemof rotational centers is eliminated, and the deformation of the robot is more similar to real muscular changes.

The invention belongs to the technical field of medical instruments for massage and health care, and particularly relates to a glove massager with specific infantile tuina acupoint modules. A middle layer is internally provided with massage blocks corresponding to acupoints on the hands of an infant, and an illness diagnoses device is in a long-arm-glove shape. The glove massager is divided into point-shaped acupoint modules, linear acupoint modules and planar acupoint modules. According to each point-shaped acupoint module, a single massage block corresponds to one point-shaped acupoint. The linear acupoint modules are massage block groups composed of stringed-bead-shaped massage blocks arranged side by side in the acupoint distribution direction, or the linear acupoint modules and/or the planar acupoint modules are formed by connecting two or more massage blocks in series to form a row and then arranging two or more rows of massage blocks to form rectangular massage block groups, wherein each massage block group corresponds to one planar acupoint. By means of the glove massager, the acupoints on the hands or forearms can be accurately positioned, and the functions of imitating manual massage of point-shaped, linear and planar acupoints, conducting intelligent storage and implementing a recipe are achieved.
