摘要： A foam transfer device (600) is described, for use with aerosol canister apparatus for producing a sclerosant foam for the treatment of, inter alia, varicose veins. The device enables diversion of an initial quantity of below-specification foam from the canister to waste, e.g. to an integral waste chamber, before dispensing a further quantity of foam for use in treatment. The switching of the flow from the waste chamber to a different outlet (618) for use is accomplished without interrupting the flow from the aerosol canister since this would cause the foam to drop below specification again. The waste chamber may be transparent so that the foam entering it can be observed and a decision made by a user when to stop diverting foam to waste. Alternatively, the foam may be diverted automatically e.g. when a set time has elapsed or a set volume of foam dispensed. The foam for use is normally dispensed into a syringe for subsequent injection into a varicose vein of a patient.

摘要： Apparatus, e.g. a syringe, for dispensing foam includes means for ensuring that only foam of adequate quality is dispensed. In use, the syringe may be filled from a pressurised canister which generates foam e.g. for therapeutic use in treating varicose veins. An initial quantity of foam dispensed from the canister may be of inadequate quality in which case it should not be used: the syringe includes means to ensure that this initial quantity of foam is diverted to a waste port or to an internal waste chamber e.g. located in the syringe plunger. Foam dispensed after the initial quantity of poor quality foam is stored in the main barrel of the syringe ready for administration to a patient in need of treatment.
摘要翻译：装置，例如用于分配泡沫的注射器包括用于确保仅分配足够质量的泡沫的装置。在使用中，注射器可以从产生泡沫的加压罐填充，例如用于治疗静脉曲张的治疗用途。从罐排出的泡沫的初始量可能是质量不足的，在这种情况下不应该使用：注射器包括确保将该初始量的泡沫转移到废物端口或内部废物室的装置，例如，位于注射器柱塞中。将初始数量不良质量的泡沫储存在注射器的主桶中的泡沫分配准备好用于需要治疗的患者。
