摘要： A pressure responsive valve assembly suitable for use in a drug-infusing device is disclosed. The drug-infusing device with a pressure responsive valve is implanted into a body cavity such as a bladder. Fluid drug is introduced into an infuser device. The rate of fluid dispensed from an infuser can be controlled based upon the pressure differential between the internal pressure of the infuser and the pressure within a body cavity. Drug infusion can be accomplished utilizing a duckbill valve assembly disposed within an infuser device. A pressurized drug is introduced outside of the resilient lips of a duckbill valve and the lips are urged toward each other. The drug comes in contact with a compressible multi-channel flow membrane located between the resilient lips of the duckbill valve. The drug flows through the membrane and out through the throat of the duckbill valve, slowing the amount of drug being released over time.

摘要： The apparatus includes a flow control conduit (2) connectable with an output portion of the heart, preferably a bypassed portion of the aorta, and includes a means of feeding heart fluid (R/O), for example blood or cardioplegia into the heart. The flow control device (1) includes in communication a variable resistance pressure control means (4) which is variably biased to a closed position to maintain on the bypassed heart region a predetermined level of pressure, to facilitate the creation of back pressure during filling of the bypassed heart region or a beat or pumping phase of the heart, and when the heart fluid pressure increases to reach a predetermined threshold, the pressure control means facilitates a release of fluid from the conduit, thus facilitating expulsion of potential emboli from the bypassed heart region, and enabling "cycling" of the heart whilst in a bypassed condition, prior to the bypassed region being taken off bypass. The invention includes preferred and alternative embodiments of variable resistance pressure control means including a hollow deformable bladder (16) biased by a compressible control fluid externally of said bladder.

摘要： The proposed respirator comprises a respiration channel (1) which can connect with the patient, high-pressure gas inlet points (53, 54) for respiration gases, a control unit (38) for setting respiration parameters and a device (15, 19) for regulating the desired dose of the respiration gases. The proposed respirator is characterised by the fact that the respiration channel (1) of a Venturi tube has a region (10) of variable cross section or a variable nozzle below an injector nozzle (9). The Venturi tube (1) is bent in such a way that the inner cylinder of the variable nozzle (10) is substantially parallel to the outflow direction of the injector nozzle (9). The variable nozzle (10) is provided with a control unit for adjusting the nozzle cross section. A device in the form of a variable cross section screen (46) is mounted above the injector nozzle (9) to restrict the volume of ambient air drawn in. A sensor (5) for measuring the oxygen concentration in the expiratory gases is provided in the Venturi tube for oxygenation monitoring. The proportion of oxygen in the respiration gases is regulated by means of the screen (46) and by the relative opening times of two solenoid valves (30, 31). The respirator can be used for a variety of flow patterns and respirator techniques and combinations thereof.

摘要： The present invention relates to apparatus for retroperfusion of tissues and organs. The apparatus comprises a catheter with a proximal end for engaging a supply of the fluid medium, and a distal end having an expandable-contractible chamber for installation into suitable vessels or organs. The expandable-contractible chamber comprises a conduit element having a fluid- filled hollow wall defining a lumen. The conduit element has a first deformable inner-facing section approximate a proximal end of the conduit and a second deformable inner-facing section approximate a distal end of the conduit element. Controlled application of a pressure at a proximal end of the conduit element causes deformation of the conduit into the lumen at its distal end thereby occluding the flow of fluid medium through the catheter. Controlled release of the pressure releases deformation of the fluid-filled conduit at its distal end thereby unblocking the flow of the fluid medium through the catheter.
摘要翻译：本发明涉及组织器官的后灌注装置。该装置包括具有用于接合流体介质的供给的近端的导管，以及具有用于安装到合适的血管或器官中的可扩张收缩室的远端。可扩张收缩室包括具有限定内腔的流体填充中空壁的导管元件。导管元件具有近似于导管的近端的第一可变形内壁部分和近似于导管元件的远端的第二可变形内表面部分。在导管元件的近端受到控制的压力导致导管在其远端处进入内腔，从而阻塞通过导管的流体介质的流动。压力的控制释放释放了流体填充管道在其远端处的变形，从而解除流体介质通过导管的流动。

摘要： An aerosolization device comprises a housing having a mouthpiece, and a flow path arrangement in fluid communication with the mouthpiece. The flow path arrangement has a flow regulating valve and a threshold valve, where the threshold valve is configured to open at a first vacuum level and to close at a second vacuum level that is less than the first vacuum level. The housing includes a region that is adapted to hold a powder in fluid communication with the flow path arrangement so that air drawn through the mouthpiece opens the threshold valve once the first vacuum level is exceeded and remains open until the vacuum falls below the second vacuum level. The flow rate of the air drawn through the mouthpiece is regulated by the flow regulating valve to remain within a certain range while the threshold valve remains open.
