The invention has as its object the provision of a medicine capable of reducing a volume of emphysema-suffering pulmonary alveoli or alveolar sacs by means of a respiratory region volume inhibitor containing a coating film formation as a main component and capable of forming a coating film in a respiratory region, characterized by being used in such a way that the coating film-forming component is administered to an emphysema-suffering pulmonary alveolar parenchyma in a human-respiratory region in an amount of 0.004 to 200 g/application, preferably 0.07 to 20 g/application and more preferably 0.5 to 5 g/application on each occasion.

Therapeutic agent for pulmonary emphysema

Disclosed herein is a medical device including: a positioning catheter to be inserted into a blood vessel in the vicinity of an affected region; a treatment catheter to be inserted to reach the affected region; and attracting means provided at respective predetermined positions of both the catheters to apply a magnetic force in a direction of attracting each other; wherein the magnetic force of the attracting means restricts floating of the treatment catheter.

Medical device and using method thereof

Disclosed herein is a method for treatment of emphysema by reducing the volume of the pulmonary alveoli or alveolar sacs which have been anomalously expanded with destruction by emphysema. The method includes a step (a) of inserting a catheter into a bronchus or bronchiole, a step (b) of injecting through said catheter a film-forming agent into the respiratory region including the pulmonary alveoli or alveolar sacs, thereby forming a film on the inner wall of said respiratory region, and a step (c) of shrinking said pulmonary alveoli or alveolar sacs.

Method for treatment of emphysema

A blood reservoir includes a blood tank, a blood accumulator connected in fluid communication with an outlet of the tank for receiving blood from the tank, and a pumping device for driving the accumulator to displace blood out of the accumulator. The accumulator typically in the form of a flexible bag is adapted to store blood in an amount proportional to the volume of blood in the tank when the volume of blood in the tank is reduced below a predetermined value. The pumping device is operated for intermittent blood delivery and can regulate the amount of blood displaced out of the accumulator.

A heat exchanger for medical treatment comprises a cylindrical blood passing space and a multiplicity of heat-exchanging tubes disposed inside the blood passing space and extending in the longitudinal direction of the blood passing space and provided with an inner space watertightly separated from the blood passing space for effecting exchange of heat between the blood being passed through the blood passing space and a heat-exchanging medium being passed through the inner spaces of the heat-exchnging tubes through the medium of walls of the heat-exchanging tubes. Blood inlet tube for introducing blood into the blood passing space and a blood outlet tube for discharging blood from within the blood passing space are expended inwardly from outside substantially along a straight lines perpendicular to the longitudinal direction of the blood passing space and tangent to the peripheral plane of the blood passsing space and communicating with the blood passing space. Optionally, the heat exchanger further comprises blood chambers disposed one each near the blood inlet and the blood outlet and each formed of an empty space destitute or devoid of the arrangement of the heat-exchanging tubes, and ribs formed on the inner wall of the blood passing space for retarding the flow of blood.

A plug for medical use includes a plug body having a column member made of a soft resilient material, and a core made of a material harder than the soft material of the plug body and disposed in the column member. The core displaces a portion of the column member outwardly and forming an outwardly bulging portion on the column member. The plug is inserted in a female opening of a BCP port of an extracorporeal blood circulation apparatus, for example, to prevent blood from leading from the BCP port.
