It has been proposed to form these glassy materials as a powder suspended in a non-aqueous liquid for injection into a patient. This method is complicated by the need to find suitable compatible liquids and to stop the glassy particles from congregating in liquid. These problems have been obviated by supporting the glassy material on a porous membrane 5 remote from the eluant. When the biological material requires administration, the eluant can be passed across the membrane 5 dissolving the glass and causing the substance to be carried by the liquid into the patient.

There is provided a syringe capable of preventing the occurrence of “link-thread” from the distal end nozzle when the cap is pulled out, even in the case where the medicinal liquid filled has a high viscosity. The inner peripheral surface ( 631 ) of the seal cap ( 63 ) in the cap ( 6 ) is brought into close contact with the outer peripheral surface ( 214 ) of the distal end side portion of the distal end nozzle ( 21 ) in the barrel ( 2 ) so that the distal end opening ( 211 ) is hermetically closed off. At the same time, the outer peripheral side of the luer lock adapter ( 22 ) is covered with the outer tubular cover ( 62 ) of the cap. The bulge part ( 213 ) is formed in the distal end side portion of the inner aperture ( 212 ) in the distal end nozzle so that the aperture diameter (d) of the distal end opening is reduced to a small aperture diameter and, in addition, the length of seal (s) by the seal cap ( 63 ) is made to be a relatively short, predetermined length. The diameter of the filled medicinal liquid to be sucked in until the vacuum breaks down when the cap is pulled out, is made very small and, in addition, the vacuum is made to break down instantly, thereby making it possible to prevent the occurrence of “link-thread” even if the medicinal liquid filled is of high viscosity.
