  • Publication number: 20190351171
    Abstract: An apparatus for supplying a patient with oxygen in emergency and/or in conjunction with CPAP devices. The apparatus includes a face mask connected to a number of quick pull adjustment devices that adjust the top and bottom of the face mask, respectively. After being slid over the head of a patient, a paramedic or other user pulls a top strap followed by a bottom strap. No further adjustment is needed in order to form a tight and secure fit on the patient between the face mask and the nose and mouth region of the patient's face. During use, a CPAP inlet or tubing, resuscitation bag, or other means for delivering oxygen is connected to an inlet of the face mask. The face mask is removed from the patient by manipulating each of the quick pull adjustment devices and then pulling the top strap and bottom strap there through.

  • Publication number: 20190351204
    Abstract: Provided is a method of manufacturing a microneedle array in which an active ingredient is concentrated at a tip while an active ingredient content is guaranteed. In order to achieve the object, a method of manufacturing a microneedle array in which needle-like recessed portions of a mold are filled with a liquid to form one dose of a patch includes determining a filling amount of the liquid from a difference in mass of the mold before and after filling of the liquid, determining a filling state of the liquid in the mold filled with the liquid, sucking the mold in which the filling amount and the filling state of the liquid are determined to be normal from a rear face, and evaporating and drying a solvent of the liquid of the sucked mold.

  • Publication number: 20190351205
    Abstract: A hydro needle system includes a vial and an array of needles. Each needle in the array is in fluid communication with the vial so as to transport the liquid from the vial to the skin. An actuator is in communication with the array of needles and is configured to apply reciprocating linear motion to the needles so as to repeatedly cause the needles to reciprocate. A casing holds the vial, the needles and the actuator. The casing includes a skin contacting surface that supports the array of needles in a predetermined angular relationship with respect to the skin. At least a portion of the casing is transparent so that the liquid in the vial can be seen therethrough to determine how much liquid remains in the vial during use.

  • Publication number: 20190351213
    Abstract: An example patient line dislodgement detection device includes a body having a plurality of openings. The plurality of openings are each configured to receive a tubing line therethrough. The device is configured such that a force applied to a tubing line causes the body to restrict fluid flow through the tubing line. During use, the tubing line is received through the body of the dislodgement device. Fluid flow is restricted by the dislodgement device through the tubing line in response to application of a force on the tubing line. A dislodgement condition can be detected based on restricting the fluid flow through the tubing line.
