  • Patent number: 4013074
    Abstract: This invention is directed to an implantable medication-dispensing device which is arranged for subcutaneous implantation. The device has hard body in which is located a liquid reservoir, an adjacent gas chamber, and a pump which is manually operable through the cutaneous layer for drawing liquid medication from the reservoir and dispensing it and directing it into the body tissue below the hypoderm. A refill membrane permits injection of medication into the reservoir so that the implanted device can be periodically refilled.

  • Patent number: 4010752
    Abstract: A disposable absorbent bandage such as a diaper has a nonwoven fibrous facing layer which includes side portions flanking a median portion, at least the side portions thereof being impregnated with a volatile liquid containing a binder to secure the interfiber connections to maintain the fiber superstructure and at least the side portions being heated to explosively puff at least the side portions of the web into a gossamer web in which the side portions have a density less than about 0.02 gm./cm..sup.3, and in which the median portion has a density of at least 0.04 gm./cm..sup.3. The differential in fiber densities between the median portion and the side portion results in substantially greater wickability in the median portion than in the side portions and reduces the tendency for leakage at the sides of the diaper.

  • Patent number: 4010751
    Abstract: An inserter for delivering soft, deformable tampons into body cavities and the combination of the inserter with a suitable tampon. The inserter is particularly useful with tampons made of resiliently deformable material, such as polyurethane sponge. The inserter is made up of a pair of telescoping elements. The outer element is in the form of a tube. The inner element may also be in the form of a tube and has a main portion slidably disposed within the outer tube and a front portion comprising a smaller diameter frontal extension axially disposed on the forward end of the main portion and having a length substantially as long as the outer element when the inner element is slidably disposed therein.In the inserter and tampon combination, the tampon is disposed within the outer tube to provide a forward head portion and a trailing skirt-like portion with at least the skirt-like portion being deformed and held in releasable compression between the frontal extension and the outer tube.

  • Patent number: 4008717
    Abstract: A small, portable, constant withdrawal device is connected to tubing, including a catheter, whose internal walls are coated with heparin. The catheter is inserted intravenously through a disposal needle into a subject such as a human being. The subject may then move about for a selected period when blood is being slowly withdrawn at a prescribed rate and collected in a container within a housing supporting the device. The collected blood may then be analyzed to permit the measurement of the integrated concentration of glucose, growth hormone or other material in blood. In addition, a portable microdiffusion chamber is incorporated between the indwelling catheter and the extra corporal tubing and is electrically connected through a sensor probe to an associated sensory responsive device. This permits continuous analysis of the withdrawn blood to determine the in vivo concentration of circulating concentrations of materials in the blood.

  • Patent number: 4008719
    Abstract: An osmotic system for delivering an agent is disclosed. The system comprises a wall surrounding a compartment and has a passageway for delivering agent from the compartment. The wall is formed of a laminae comprising a lamina consisting of a multiplicity of materials in laminar arrangement with a lamina consisting of a material or of a multiplicity of materials to provide a laminated wall that is permeable to agents and maintains its integrity during the delivery of agent. The compartment contains an agent that is soluble in an external fluid and exhibits an osmotic pressure gradient across the wall against the fluid, or the agent has limited solubility in the fluid and is mixed with an osmotically effective compound soluble in the fluid and exhibits an osmotic pressure gradient across the wall against the fluid.

  • Patent number: 4006743
    Abstract: A small, portable, constant withdrawal device is connected to tubing, including a catheter, whose internal walls are coated with heparin. The catheter is inserted intravenously through a disposable needle into a subject such as a human being. The subject may then move about for a selected period when blood is being slowly withdrawn at a prescribed rate and collected in a container within a housing supporting the device. The collected blood may then be analyzed to permit the measurement of the integrated concentration of growth hormone or any substance whose concentration in blood fluctuates widely.In addition, a portable microdiffusion chamber is incorporated between the indwelling catheter and the extra corporal tubing and is electrically connected through a sensing probe to an associated portable sensory responsive device. This permits analyzation of the extracted blood to determine the in vivo concentration of circulating concentrations of the diffusable fraction of biological materials in the blood.

  • Patent number: 4003379
    Abstract: An apparatus for dispensing drugs and other medications within the body leaves the patient ambulatory and is adapted to be entirely implanted and to dispense such substances over a long period of time, e.g., one to several years, in accordance with the actual needs of the patient. A self-powered dispensing device stores a single or plural substances in powdered, liquid, or other dispensable form and utilizes a compressible container, i.e., a bellows, for withdrawing such substances from storage and dispensing to the body. The dispensing operation may be on a fixed schedule or may be controlled by monitoring single or plural sensors implanted in the body and evaluating the sensed data in order to control both the conditions under which and the kind of dispensing which takes place. Dual dispensers and dual medication may be employed.

  • Patent number: 4002172
    Abstract: A disposable diaper having a facing sheet defining a diaper inside surface for direction toward an infant and a backing sheet defining a diaper outside surface is provided with adhesive tabs which are slit within the perimetric limits thereof to form a central flap spaced from the edges of the tab. The tab includes a free end and a fixed end. An adhesive coating is provided on at least one face of the flap, free end and fixed end. The fixed end is permanently attached to the diaper backing sheet and the flap is permanently attached to the facing sheet by means of the respective adhesive coatings so that stresses exerted on the tab are distributed to both the facing sheet and the backing sheet when the diaper is secured about an infant.

  • Patent number: 3999547
    Abstract: A disposable diaper comprising a waterproof back sheet, a hydrophobic sheet, and an absorbent pad sandwiched between the back sheet and the face sheet. The diaper is folded to define a box pleated configuration having a central panel, inwardly extending panels and outwardly extending panels with the inner edges of the inwardly extending panels being in abutting relationship. Sealing strips of waterproof material separate from the back sheet are secured on the face sheet. The sealing strips are formed by folding an excess width of the back sheet over the face sheet forming side flap portions, and then cutting the side flap portions free from the back sheet. The sealing strips may be folded inwardly toward the center of the diaper to form fluid catching seals.
