    摘要: A portable elastomeric bladder-powered infusor for dispensing drug in liquid form under pressure at a predetermined flow rate is disclosed. The main elements of the infusor are a tubular housing, a plug/flow control assembly fixed in one end of the bladder, an axially slidable piston/filling port assembly within the housing, and a tubular bladder. The plug and piston assemblies each has an axial post about which the bladder ends are attached. When the bladder is not charged with drug, the posts fill the bladder's lumen and their ends abut. Drug is charged to the infusor by inserting a drug-filled syringe into the open end of the housing with the syringe's needle entering an axial bore in the piston, penetrating a septum that blocks the bore, and extending into the axial post. The force exerted on the piston by the syringe is transmitted to the fixed plug assembly via the axial posts. Drug is plunged from the syringe causing the posts to separate and the bladder to expand axially and radially. Once the bladder is filled, the syringe is withdrawn, with the septum sealing itself. The drug is dispensed from the bladder via the plug/flow control assembly and a conduit that is connected to that assembly and extends to the infusion site.

    摘要: A system is provided for the administration of a medicament, such as insulin, to a patient in small, controlled doses over an extended period in response to a continuously generated force. The force may be maintained continuously on a reservoir of the medicament in intermittent communication with a site in the body of the patient through a flexible and compressible tube. A constrictor about the tube keeps it normally closed except when a separate force is exerted to open the constrictor and permit the medicament to flow through the tube for a predetermined period. Alternatively, the continuously generated force may be applied intermittently to the medicament reservoir through the action of an escapement mechanism.

    摘要: First and second means respectively provide for a passage of first and second particular volumes of fluid from first and second sources at first and second controlled rates to a patient. Each of the first and second means is constructed to provide on a positive basis for the flow of fluid at the particular one of the first and second controlled rates. Third means are operatively coupled to the first and second means for providing for an initial operation of the first means in producing a passage of fluid from the first source to the patient. Fourth means are responsive to the passage of the first particular volume of fluid to the patient for interrupting the operation of the first means and instituting the operation of the second means in providing for the passage of fluid from the second source to the patient.The passage of fluid from the first means to the patient is also interrupted when all of the fluid has passed from the source. At such a time, an air sensor associated with microbore tubing indicates that fluid is no longer passing through the tubing. At such a time, however, a drip chamber receiving the fluid from the microbore tubing still has fluid because the volume of the drip chamber is greater than the volume of the microbore tubing. Since the fluid from the drip chamber is introduced to the first means for passage on a controlled basis to the patient, the air sensor becomes operative to interrupt the flow of fluid to the patient at a time when air bubbles cannot flow to the patient. The drip chamber is made from a resilient material so that it can be initially operated to squeeze into the source any air bubbles existing in the drip chamber before fluid starts to pass from the first source to the patient.

    摘要: Injecting apparatus comprises means to hold the apparatus against a living body, and a medical liquid in a reservoir of the apparatus is pumped by a pump means which is driven by movement of some portion of the living body, so as to be injected into the living body. The medical liquid may be injected little by little, in which case each cycle of the pump means is effected by a plurality of movements of the living body. The reservoir is made of resilient material, for example, silicone rubber. A modified reservoir comprises an inner bag and an outer bag, with an intermediate space therebetween, which may be filled with a physiological solution of sodium chloride.

    摘要: An apparatus for infusion of liquids into human or animal bodies which comprises a liquid reservoir having a reduced-pressure generating means associated therewith and an active delivery-dosing means, such as a roller pump, operationally coupled with the reservoir and with an outflow catheter having outflow opening within the body being infused. The reduced-pressure generating means, such as a volatile fluid, for example, a halogenated hydrocarbon, maintains a pressure at the point of connection between the reservoir and the active delivery-dosing means at a reference value which is lower than the pressure prevailing at the outflow opening of the outflow catheter.

    摘要: The intravenous feeding pump actuator of the present invention is driven by a small, very slow speed motor and a gear train, such as one rotating the output shaft at a speed of one revolution per minue (1 r.p.m.). The single motor drives a readily replaceable cam which is slipped into position on the drive shaft and needs no other means for attaching it thereto. Each of the cams normally supplied with the actuator is designed to give a predetermined number of rocking movements per minute to a cam follower which directly operates the associated intravenous pump, and simultaneously controls the limit of travel of the cam follower and thus the length of the stroke of the pump operator. It will be understood that each of the cams will provide for a different flow rate for the associated pump by controlling the number of strokes per minute and the length of each stroke and is readily changeable so that one can be quickly and easily removed and another placed in its stead when determined by operating conditions.
