摘要:
An instillator having a medicator-connecting mouth into which a medication that cannot be subjected to sterilization may be introduced by a simple operation and in a germ-free condition so that the medication is mixed with a pharmaceutical liquid contained therein, said instillator being composed of an outlet member, a medicator-connecting mouth and a body, said medicator-connecting mouth comprising a communicating pathway which communicates with the inside of the body upon use, a germ-trapping filter disposed in the middle of said communicating pathway, a sealing means for sealing said communicating pathway disposed between said germ-trapping filter and said body, and a connecting means disposed at one end of said communicating pathway opposite to the body, the body made of a flexible material being filled with a pharmaceutical liquid, sealed and subjected to autoclaved sterilization, the connecting port of the instillator having a connecting duct tightly fitted into the port.

In a medical container comprising a flexible vessel containing a fluid, inlet means attached to the vessel for admitting another fluid into the vessel, and an outlet, a tubular member is extended through the vessel wall as the inlet means and closed at the outer end with a plugging member to shut off the tubular member channel from the exterior and provided at the inner end with a bacterial filter, the plugging member permitting access to the tubular member channel from the exterior when the other fluid is to be admitted into the vessel. A breakable closure member is further mounted on the inner end of the tubular member to shut off the filter member from the interior space of the vessel, but is breakable to permit the communication of the interior space with the tubular member when the other fluid is to be admitted.

A container for therapeutic use is formed of a main body, which is made of a flexible resin and provided with a bag portion. The bag portion is formed in a flat shape at at least a part thereof where mutually-opposing walls of the bag portion are peelably welded together at inner surfaces thereof to form a welded region. A hole is formed as an attachment hole through at least one of the mutually-opposing walls in the welded region. A holder with a medicament placed therein, said medicament being prone to a change in property or color upon absorption of moisture, is hermetically attached to the at least one wall over the attachment hole to seal the medicament in the holder. A moisture-barrier member with a desiccant placed therein is arranged on a side opposite to the holder so that the other wall of the bag portion is hermetically covered by the moisture-barrier member at a position at least corresponding to the attachment hole.
摘要:
A surface treatment method for improving the adhesiveness of a surface of a molded article made of a polyolefin resin with a printing ink, which entails irradiating the surface with an abundance of high-energy ultraviolet radiation from a high-output low-pressure mercury vapor lamp having an envelope made of synthetic quartz glass, and wherein the lamp has a wattage per unit lamp length of about 0.1-0.5 W/mm.
摘要:
Disclosed is a medical fluid-filled plastic container which includes (a) a sealed inner envelope of plastic material filled with a medical fluid containing a component subject to deterioration by oxygen, (b) a deoxidizer, and (c) a sealed outer envelope of plastic material enclosing both the medical fluid-filled inner envelope and the deoxidizer, as well as several methods of making such a medical fluid-filled plastic container. This medical fluid-filled plastic container will prevent the medical fluid therein from being deteriorated even it it is subjected to steam sterilization or is stored for a long period of time.
摘要:
Medical permeating membranes in a zone through which a body fluid flows, said membranes having lateral surfaces in said zone, comprising permeable membranes of regenerated cellulose and a film of a fat-soluble vitamin and glycerin on said lateral surfaces of said membranes in said zone for flow of body fluid.

A connector for medical tubing for liquid transfusion includes a short tubular male connector member made of thermally resistant corrosionproof materia; a short tubular female connector member made of thermally resistant corrosionproof material; and a fitting surface portion on the outer surface of an insertion end of the male connector, shaped in the male form and made of a material having a smaller thermal expansion coefficient than the material of a corresponding fitting surface portion on the inner surface of an insertion end of the female connector shaped in the female form. The fitting surface portion of the insertion end shaped in the male form, and the fitting surface portion of the insertion end shaped in the female form, are of relative sizes such as to permit the insertion ends to be connected to and separated from each other by shrink fit utilizing the difference between the thermal expansion coefficients thereof. A medical solution bag device using the connector is also disclosed.
摘要:
A medical bag and method of manufacturing the bag from a thermoplastic resin by irradiating a ferromagnetic heating element which has been prepositioned between the mouth and receiving portions of the bag and which is caused to generate high frequence-induced heat. During subjection of the heating element to a high frequency magnetic field, the mouth portion and receiving portion of the bag melt about the element so that mouth portion, element and receiving portion are bonded together. This technique can also be suitably used for thermoplastic resins, for example, polyolefin resins, to which conventional high-frequency bonding cannot be applied.
摘要:
A connector for therapeutic tubing comprising a tubular male connector member made of thermally resistant corrosionproof material, a tubular female connector member made of thermally resistant corrosionproof material and a locking mechanism coupled to the connector members and used for locking the union between the connector members. A medical solution bag device comprises a flexible bag, a flexible tube connected to the bag flexible, a further tube adapted to be connected to the flexible tube and the above mentioned connector for connecting the flexible tube to the further tube.
