Abstract: A retained needle structure of a comprises a syringe needle with one or more fastening portion, a catheter with a cannula having a flexible tube, as well as a syringe cover with an aperture and gliding portion. The syringe needle has an inserting portion which is axially operated by users to enhance safety practice in clinical use. First design is the sliding slot has a deflected slant portion at the distal end. When the fastening portion is at the rear end of sliding slot, the injection needle is already inside of syringe cover. At the same point, body of the syringe needle is deflected laterally from the center of the syringe cover. The second design is used the levering effect from gravity of syringe cover. When the fastening portion is at the rear end of sliding slot, the syringe cover is vertically rotated from the original center of the syringe cover.

Abstract: The invention provides a strain gauge which includes a fabric base and at least one conductive yarn. In addition, the fabric base is weaved with a plurality of non-conductive yarns, and the fabric base thereon defines a sensing direction. Moreover, each of the conductive yarn is gimped by a textile process with one of the non-conductive yarns and is woven through the fabric base along the sensing direction. Furthermore, the at least one conductive yarn is capable of being applied by an electric power; when an external force acts on the fabric base, the geometrical property of the at least one conductive yarn alters so that a change of an electric property associated with the applied electric power is sensed to indicate an elongation of said strain gauge applied by the external force along the sensing direction.

Abstract: The invention provides a physiological function monitoring system for monitoring a first physiological function of a user. The physiological function monitoring system includes a first detecting device, N second detecting devices, a signal processing device, and a communicating device, N is a nature number. Furthermore, the physiological function monitoring system is applied in remote monitoring. In addition, the monitoring system is capable of detecting N second physiological functions of the user by the N detecting devices, to help making correct judgment on the first physiological function of the user.

Abstract: An injection apparatus includes an accommodating body, having a chamber formed therein, a needle retracting hole with a diameter smaller than the chamber and disposed at an end of the accommodating body and coupled to the chamber, a sliding path disposed on at least one side of the accommodating body, a first position defined on the sliding path and disposed proximate to the needle retracting hole, a slanting surface disposed on the sliding path and away from the needle retracting hole, and a second position defined on the slanting surface; and an injector, including a syringe head being smaller than the chamber and installed in the chamber, an injection needle disposed at an end of the syringe head and passing through the needle retracting hole, and a pushing portion disposed on at least one lateral side of the syringe head for sliding with respect to the sliding path; such that the pushing portion can be pushed from the first position to the second position along the sliding path, and the syringe head slide

Abstract: A method and an instrument feed back the physical condition monitored from the fetus and the gravida automatically. Various monitoring methods are adopted to automatically set up monitoring intervals and time points. While the physical condition detected is good, it keeps the preset monitoring time intervals; if the feedback condition is not good, then the monitoring intervals and time points would be adjusted, and the instrument informs the gravida for further management. Through that, it generalizes all the values monitored at different time. The detailed result could be got from feedback of the repeated monitoring and cross monitoring thereby automatically, then well informing the gravida about the condition of herself and her fetus to get proper medical assistance.

Abstract: A one-time safe administration set structure comprises essentially a protective rider, a gliding part, and a hose, wherein said protective rider is provided thereon with a slideway, said slideway is provided on its rear side with a receptive portion, and said gliding part is engaged with a hand pushing part through a sliding block on the upper edge of said gliding part. In use of said one-time safe administration set structure, said hand pushing part is pushed forward such that the rear end of said gliding part is stopped by the protruding button provided near the front end of said slideway, thereby actions of injection or drawing can be carried out.

Abstract: A single-use safety injector structure includes a syringe needle, a protective cover and a syringe. The syringe needle is connected to the syringe via an insertion portion. The outer periphery of the insertion portion is provided with a gliding block. The gliding block includes a base, a guiding rod and an upper stopping portion. The outer periphery of the protective cover is provided with a gliding track. One or both sides in the vicinity of the front end and rear end of the gliding track are provided with salients. The gliding track is provided with one or more non-return stopping blocks behind and in the vicinity of the rear-end salient. The protective cover is sleeved around the outer periphery of the syringe needle. By means of the guiding rod, the injection needle penetrates through the gliding track of the protective cover. By means of the base, the syringe needle is sustained against the inner wall of the protective cover.

Abstract: An intra-venous catheter structure includes a syringe, a catheter, and a cap. The syringe has one or more buckle set at a side edge thereof. The cap has an opening set at a front end thereof and plural hooks set on a front end of the opening, plural sliding plates extendedly set on an outer edge of a back end of the cap corresponding to a position and a number of the one or more buckle of the syringe and a sliding trough formed on each of the plural of sliding plates, and a fastening portion formed on each the sliding trough at a portion approaching to a terminal end thereof.
