With Collapsible Bulb Means Patents (Class 604/75)
  • Patent number: 4964852
    Abstract: A one-way valve positioned between the nozzle and container of a disposable douche, which is opened and closed by axial movement of the nozzle relative to the container, permitting discharge of the douche contents without permitting backflow. The neck of the container opening having an intermediate cap with axial discharge holes and a flexible valve disk overlying such holes all within the bore of the base of the nozzle. In the closed position, the inner shoulder of the nozzle base seat against the flexible valve disk presenting discharge of the contents through the discharge opening of the intermediate cap. With the axial displacement of the nozzle away from the main body of the container the valve disk, freed of the internal restraining shoulders of the nozzle base, can flex to permit flow of the contents of the container into the nozzle.

  • Patent number: 4961727
    Abstract: A dispensing package adapted for delivering medicine to a nasal cavity for absorption into the bloodstream comprises a flexible-walled container having a discharge head with a swirl chamber and a dip tube depending therefrom into the container. In use, the container is squeezed to drive liquid up the dip tube and into the swirl chamber to be discharged upwardly into the nasal cavity in the form of a fountain of relatively large droplets. The swirl chamber operates in the absence of air.

  • Patent number: 4794915
    Abstract: A method for mechanically stimulating the nipples of a pregnant woman for diagnostic and therapeutic effects. A nipple stimulator device is placed over a woman's nipple, and an intermittent reduced pressure is induced in the interior of the apparatus by a pump. An elastic membrane on the stimulator device is drawn inward by the reduced pressure, and in so doing acts to massage the breast nipple and the adjacent breast. A gentle, soft massage of the nipple is thereby provided to yield the desired stimulation to produce hormones, for example, useful in accelerating labor or conducting contraction stress tests in a pregnant woman.

  • Patent number: 4740196
    Abstract: A nursing apparatus is utilized for stimulating lactation in the female human breast. A breast receiving opening permits the positioning of the apparatus over the female breast, and means for pressurizing and depressurizing an attached chamber then operates to provide a suction action. Additional stimulation is provided by an electrically powered vibrator, while the breast receiving portion includes a chamber which may be filled with warm water to thus simulate the temperature of an infant's mouth.

  • Patent number: 4705504
    Abstract: A breast pump having a hollow, squeezable, resilient suction member with an inlet opening for accommodating a nipple and receiving a liquid into the suction member as it is being inflated, and a discharge opening for discharging liquid into a disposable bag as the suction member is being squeezed. The pump is relatively small to fit into a lady's purse when not in use.

  • Patent number: 4693709
    Abstract: An irrigation syringe is provided which includes a barrel having an axially extending annular groove open at the proximal end for receiving the connector portion of a resilient compressible syringe bulb in tight frictional fitting relation. The syringe barrel is adapted to receive, instead of the bulb, a plunger having a piston that may be inserted into the barrel to provide a piston-type syringe so that the barrel can be used either with a syringe bulb or a syringe plunger. The inner wall of the groove has a plurality of slots so that if the syringe barrel is employed as a funnel, liquid will flow from the groove into the barrel.

  • Patent number: 4680028
    Abstract: A breast receptor for a breast pump having means for creating a vacuum within the breast receptor in which the wall thicknesses of the flexed portions of the receptor engaging the nipple and areola are reduced in order to produce optimum lactating conditions, including optimum responsiveness to the external touch stimulus, and which will most nearly simulate the mouth of a suckling infant.

  • Patent number: 4542751
    Abstract: A sweat-collection device formed as a solid body having a shallowly concave, sweat-collecting surface at a face thereof defining a concavity with a rim lying wholly within a common plane for firm placement over an iontophoresis-stimulated area of a person's skin to collect sweat from the skin area and pass it through a bore at the center of the concavity. The concavity is so shallow that no dead space occurs between the collecting surface and the skin and flesh bulged into the concavity when the device is applied to a patient whose sweat is to be collected for testing. Optionally, the concavity may be modified without introducing dead space thereinto, to incorporate barrier means for preventing unusually soft skin and flesh of infants and some adults from bulging into and closing the bore.
