Abstract
1485842 Administering radioactive gases GENERAL ELECTRIC CO and MEDIPHYSICS Inc 15 Aug 1974 [15 Aug 1973 (3)] 36041/74 Heading A5T [Also in Division B4] A capsule 23, Fig. 2, containing a gaseous radioisotope for inhalation by a patient so that the lungs may be examined, comprises a shearable, gas-impermeable material consisting of vinyl-vinylidene chloride, polyethylene terephthalate or polysulphone, said capsule further containing a physiologically benign absorbent for products formed by the effect of radiation on the capsule material. The said absorbent may comprise moisture or water vapour. The' capsule is, in use, held in a cavity 25 of a valve assembly 22, the capsule being sheared open on rotation of a valve plug 32. A mouthpiece 21 is provided at one end of the valve assembly and a breathing bag 24 at the other end. The valve assembly is made of a lead alloy comprising about 5% by weight tin, and about 11% by weight antimony, the balance being lead. The radioisotope may be xenon-127, xenon-129, xenon-133, krypton-85 or radon-232. The capsule may contain air, nitrogen or oxygen as a diluent. A rubber bulb expressor (41), Fig. 4, (not shown) may be attached to said other end of the valve assembly instead of bag 24, said bag then being positioned between said one end of the valve assembly and said mouthpiece. The expressor (41) has a one-way valve (42) which admits air to the apparatus. A cannister (36) Fig. 3, (not shown), containing material for absorbing water vapour and carbon dioxide in the air exhaled by the patient may be included in the apparatus. The valve assembly may be used as a transportation unit for the radioactive gas-containing capsule when end plugs 35, Fig. 7, also of the lead alloy, are fitted into the valve-body 26 at the ends of cavity 25. A handle 33 is attachable to the plug to effect rotation thereof to break the capsule and release the gas.
