Abstract
A device for monitoring and limiting the fluid pressure during parenteral or intravenous administration of medication to a patient. The device includes a manometer tube connected at its lower end via a stopcock to the tubing through which the medication is administered under pressure, such as from a fluid pump. A graduated manometer bag is attached at the upper end of the manometer tube for receiving medication which overflows the manometer tube in the event excessive pressure is encountered as would happen if a blockage in the patient were to occur.
Claims6
A device for monitoring and regulating the fluid pressure to a patient receiving a driven fluid through a catheter comprising:
- (a) a tube means for communicating the driven fluid from a supply to a patient;
- (b) a manometer in circuit with said tube means for indicating the fluid pressure therein;
- (c) overflow means comprising a manometer bag for limiting the fluid pressure to a selected value, said manometer bag communicating with said manometer to receive fluid when the fluid pressure exceeds said selected value.
A device for monitoring and regulating the fluid pressure to a patient receiving a driven fluid through a catheter comprising:
- a manometer tube,
- a valve means attached to said manometer tube at its lower end,
- at least one tube for administering the fluid to the patient, said tube being attached to said valve means and communicating with said manometer tube when said valve means is in an open position, and
- a manometer bag attached to said manometer tube at its upper end and communicating therewith for limiting the fluid pressure to a selected value and capturing fluid which overflows from said manometer tube when the fluid pressure exceeds the selected value.
