    Abstract: A hand-held applicator (10) for self-administration of a semi-solid medicament comprises an applicator head (14) with one or more elongate dispensing nozzles (40) and an applicator body (12) for housing a medicament reservoir, such as a cartridge (20). The applicator has a pump assembly and an actuator (30) for pumping the medicament from the one or more of the dispensing nozzles. The applicator head and applicator body are fixed relative to each other in use such that movement of the nozzle or nozzles away from the scalp or other body area during actuation may be avoided. The applicator may further include an application face for spreading medicament over a body area thereby enabling dual functionality as a scalp and body applicator. A dispensing system in the form of a dispensing head and cartridge therefor is also described and characterised by venting features for improving priming of the dispenser. Such priming means are suitable for use in the applicators of the application.

  • Publication number: 20140364818
    Abstract: A medical spraying device and method for irrigating a wound, in particular lavage system, having a liquid reservoir for a medical irrigation liquid or a connection for such a liquid reservoir, and a compressed gas reservoir. The compressed gas reservoir is connected or connectable via a pressure line to the liquid reservoir, such that the irrigation liquid can be pushed by the gas pressure of the compressed gas reservoir acting on the irrigation liquid through a nozzle in order to produce a spray cone. A pressure reduction valve is arranged in the pressure line and limits the gas pressure acting in the liquid reservoir on the irrigation liquid. The device and method produce a spray cone of a medical irrigation liquid in which a gas pressure is limited using a pressure reduction valve, wherein the gas pressure limited by the pressure reduction valve is conveyed through a pressure line to a liquid reservoir of the medical irrigation liquid.

  • Patent number: 8834434
    Abstract: A surgical tissue therapy device includes a sealant layer and a collection chamber. The sealant layer functions so as to create a sealed enclosure or space between it and the surface of a patient by forming, preferably, an airtight seal around a surgical area of skin trauma. The closed incision tissue therapy device also comprises a collection chamber, which may comprise an elongate tubular chamber with a plurality of longitudinally spaced openings. The collection chamber may be configured to be in fluid communication with the sealant layer and the area of skin trauma and functions as to distribute the negative pressure applied to a surgically closed area of skin trauma. Preferably, the pressure under the sealant layer is reduced by expanding the volume of the enclosure space and thereby decreasing the density of air molecules under the sealant layer.

  • Patent number: 8246590
    Abstract: A surgical tissue therapy device includes a sealant layer and a collection chamber. The sealant layer functions so as to create a sealed enclosure or space between it and the surface of a patient by forming, preferably, an airtight seal around a surgical area of skin trauma. The closed incision tissue therapy device also comprises a collection chamber, which may comprise an elongate tubular chamber with a plurality of longitudinally spaced openings. The collection chamber may be configured to be in fluid communication with the sealant layer and the area of skin trauma and functions as to distribute the negative pressure applied to a surgically closed area of skin trauma. Preferably, the pressure under the sealant layer is reduced by expanding the volume of the enclosure space and thereby decreasing the density of air molecules under the sealant layer.

  • Patent number: 8088093
    Abstract: A tampon assembly used for penetration injuries to provide hemostasis and simultaneous broad spectrum antibiotic/anesthetic application. The tampon includes a helically-wound absorbent member impregnated with coagulant, covered with biodegradable or plastic accordion-pleated sheath including a bioluminescent tape outer marker. The device would also contain a measured dose of antibiotic/anesthetic suspension sealed within the confines of the outer sheath. The outer sheath would preferably have a perforated petal-shaped tip to enable wound insertion followed by through passage of the contained wound packing and treatment liquids/emulsions, etc. A radio opaque cotton withdrawal string would attach to the absorbent member at the end facing the wound opening. An insertion stick/plunger is used for tampon deposition within the wound. Manual pressure on the plunger would cause seal rupture and expulsion of the wound packing and treatment through the ruptured tip of the sheath.

  • Patent number: 8057446
    Abstract: Methods and devices transmit micromechanical forces locally on the millimeter to micron scale for promoting wound healing. Micromechanical forces can selectively be applied directly to tissue, in some embodiments, by using microchambers fluidically connected to microchannels. Each chamber, or in some cases, group of chambers, may be associated with a valve to control vacuum pressure, positive pressure, liquid delivery, and/or liquid removal from each chamber or group of chambers. Application of embodiments of the invention may shorten wound-healing time, reduce costs of therapy, enable restoration of functional tissue, and reduce the need for more invasive therapies, including surgery.

  • Publication number: 20110270227
    Abstract: An enteral dispenser and associated method of use is provided for enterally dispensing liquid medications. The enteral dispenser includes a barrel having a number of dosing gradations arranged upon its outer surface. The barrel receives a liquid medication that has been selected from a predefined group of liquid medications having a range of colors. A plunger is moveably disposed within the barrel, and a piston is coupled to a distal end of the plunger. The piston has a peripheral portion for selective alignment with respect to a desired one of the dosing gradations and is a color that is optically differentiable from each of the colors represented within the range of colors of the predefined group of liquid medications, such that an user may differentiate between the color of the a peripheral portion of the piston and the color of any selected liquid medication.
