Definitions

  • This invention relates to the field of intravenous feeding and infusion of blood, plasma, liquid medications and the like, and has for its objective the creation of an intravenous infusion device by which such liquids can be infused intravenously into a patient through a controlled, regulated pressure means of forcing the liquid or fluid out of its receptacle or container and, through appropriate tubing and a hypodermic needle, into the vein of the patient.
  • This objective is accomplished by providing a container for the fluid and an independent container for compressed air or gas, and, when infusion is required, coupling the latter container to the former so that the compressed gas in the latter is directed into the former to force its contents out through a tube-connected hypodermic needle.
  • the device further is provided with means to control the rate of flow of the fluid, to adjust the rate of flow, and to detect any obstruction to the flow, such as when the needle slips out of the vein or becomes imbedded in tissue.
  • intravenous infusion devices include manual or mechanical pumps to feed the fluid into the vein.
  • the disadvantages thereof, among others, include the necessity for an attendant and constant supervision, as well as the cumbersome and expensive equipment required.
  • a recently developed intravenousinfusion device employs the use of an ampoule or capsule, containing chemical ingredients, which is disposed within an expandable envelope containing a reactive agent or chemical, all disposed with in a flexible fluid container, with the capsule frangible within the envelope to commingle the respective contents to generate a gas which causes the envelope to expand and thereby force the fluid out of the container.
  • the disadvantages of this device include the ever-present possibility of accidental fracture of the capsule before the device is ready for use, such as during handling packing or transportation, the danger of particles of the broken capsule finding their way into the fluid and thence into the tubing, as well as deterioration of the chemicals with the passage of time.
  • the fluid container itself is adapted-to be placed near, but not on the patient adjacent the infusionarea, so that movement of the patient is likely to cause unnoticed disengagement or dislodgeinent of the hypodermic needle.
  • the present invention which provides a fluid container constructed to be attached directly to the body of the patient in the immediate area of infusion,
  • air or gas adapted to be coupled to the fluid container so as to I release the air or gas into the fluid container in such a manner as to force the fluid out of the latter, through an appropriate discharge outlet for infusion intothe patient.
  • the air or gas is directed into the fluid container below a separating diaphragm, so that no contact is ever, made between the infusion fluid and the air or gas.
  • a second important object of my invention lies in the provision of an intravenous infusion'device by which a fluid can be administered to a patient intravenously at an evenly regulated flow.
  • a third important object of my invention lies in the provision of an intravenous infusion device by which the flow of fluid into the patient may be adjusted in accordance with the density or viscosity of the fluid.
  • a fourth important object of my invention lies in the provision of an infusion device of the type described, which will completely eliminate the possibility of air being introduced accidentally into the vein of the patient.
  • a fifth important object of my invention lies in the provision of an infusion device of the type that requires no supporting equipment for its use.
  • a sixth important object of my invention lies in the provision of an intravenous infusion device which is inexpensive to manufacture, and hence disposable after initial use, and which is simple to operate.
  • Still another important object of my invention lies in the provision of a device of the type which permits the patient to be ambulatory while it is being used, and does not compel him to be immobilized.

  • FIG. 2 is an enlarged cross-sectional view, taken on lines 2-2 of FIG. 1;
