Apparatus and methods for control of intravenous sedation
First Claim
1. In combination, an apparatus for regulating the flow of sedative supplied from a supply source through an intravenous line to a patient comprising:
- a supply source for supplying sedative, an intravenous line connected theretoa controller unit, said controller unit receiving a pulse oximetry signal from a pulse oximeter, said controller unit generating a control signal based on said pulse oximetry signal; and
,a flow control regulator, said flow control regulator receiving said control signal, said flow control regulator physically constricting said intravenous line and regulating the flow of sedation to a patient responsive to said control signal from said controller, said flow control regulator being located between the supply source and the patient to control the flow of sedation.

Abstract
Apparatus and methods for controlling the administration of intravenous drugs for sedation of a patient. Safe and controlled levels of sedation are provided by the use of a system for continous monitoring of patient pulse oximetry levels during the sedative'"'"'s adminstration. Adequate levels of sedation that are clinically desirable are accomplished by the device, safely and smoothly, without the risk of respiratory depression. Preestablished oximetry ranges are provided before and/or during administration of the analgesic as the maximum and minimum acceptable saturation levels. Levels of sedation are continuously adjusted in response to increases or drops in oxygen saturation to smoothly maintain the saturation levels within the preestablished parameters.

8. An apparatus for regulating the flow of sedative supplied from a supply source through an intravenous line to a patient comprising:
-
a controller unit, said controller unit setting a predetermined range of acceptable oxygen saturation levels, said predetermined range of acceptable oxygen saturation levels including a minimum acceptable oxygen saturation level, said controller unit receiving a pulse oximetry signal from a pulse oximeter, said controller unit generating a control signal based on said pulse oximetry signal and said predetermined range of acceptable oxygen saturation levels; and
,a flow control for regulator, said flow control regulator receiving said control signal, said flow control regulator regulating the flow of sedation to a patient through said intravenous line responsive to said control signal from said controller, said flow control regulator being physically capable of constricting the flow of sedation through said intravenous line. - View Dependent Claims (9, 10, 11, 12, 13, 14)
