The device is configured such that, in use, the heating element heats the fluid in the at least one fluid chamber to at least partially evaporate the fluid so that the vapor pressure in the at least one fluid chamber increases until the fluid is expelled out of the at least one fluid chamber through the fluid outlet towards the medicament receiving element and entrains the medicament towards the patient's skin.

Abstract: A hybrid blunt cannula with puncture needle assembly provides an outer cannula member comprising a needle channel, an eye, a stopper member disposed at the second end of the cannula member, and an inner needle disposed inside the needle channel and coupled to buttons. The buttons follow a translation path between a static position and an insertion position. The static position enables the free end of inner needle to be proximal to the second end of the outer cannula member, and within the needle channel. The insertion position enables the free end of the inner needle to be proximal to second end of the outer cannula member and partially outside of the outer needle's channel. The free end of inner needle is operable to penetrate the stopper member while in insertion position for discharge of a liquid through the eye.

Abstract: Catheter assemblies may include introducer needles having a notch or similar structure that allows flashback blood to enter the annular space between a catheter tube and an introducer needle of an IV catheter. The presence of flashback blood in this annular space can provide a clinician with an early, visible indication that a needle has entered a vein. The notch, however, may create a leak path for blood to escape outside of the catheter assembly, unless contained. Disclosed herein is a notch containment that prevents the notch from providing a leak path for blood to escape outside of the catheter during or after needle withdrawal.

Abstract: The present invention relates to a filtering syringe, and more particularly, to an apparatus obtained by improving a syringe provided with a filter means for filtering foreign substances such as glass fragments of an ampoule, so as to prevent an injection needle or an injection flow passage from being contaminated with the foreign substances while allowing a liquid medicine to be smoothly sucked with a smaller force. The filtering syringe is configured such that the injection needle or the injection flow passage is isolated from the suction flow passage which is upstream of the filter means and in which the foreign substances may remain together with the liquid medicine, thereby allowing the liquid medicine to be sucked with a force less than that required for a conventional syringe and thus maximizing user's convenience and marketability of the syringe.
