US Patent:

20210308374, Oct 7, 2021

Filed:

Mar 15, 2021

Appl. No.:

17/201276

Inventors:

- San Diego CA, US
Prabhu Chinnaiah - San Diego CA, US
Richard Stor Wu - San Diego CA, US

International Classification:

A61M 5/168
A61M 5/315
H04W 4/14
H04W 4/20

Abstract:

A method may include receiving, from a volume meter at a pump configured to deliver medication to a patient, data indicative of a volume of a medication present in a syringe inserted in the pump. A first counter may be updated, based on the data, in response to the medication being delivered to the patient as a first dose type. A second counter may be updated, based on the data, in response to the medication being delivered to the patient as a second dose type. The volume of the medication delivered to the patient may be determined based on the first counter and/or the second counter. An electronic alert may be sent to a mobile device in response to one or more anomalies being present in the volume of the medication delivered to the patient. Related methods and articles of manufacture, including apparatuses and computer program products, are also disclosed.

International Classification:

A61M 5/168

G16H 40/40
G16H 40/63

Abstract:

A system including a tube and a force sensor coupled to a wall of the tube via a restraining element and configured to obtain a value of a tubing force when the tube is deformed by the restraining element. The system includes a processor to determine parameters for fitting a curve including the value of the tubing force, to determine a fluid pressure value for a fluid in the tube based on the parameters for fitting the curve, and to activate an alarm responsive to the fluid pressure value and to the parameters for fitting the curve when an occlusion condition is identified in the tube. The parameters for fitting the curve comprise at least one time-decaying parameter(s) associated to the tubing force. A method for using the system and a non-transitory computer readable medium including instructions to perform the above method are also provided.

Inventors:

- San Diego CA, US
Prabhu Chinnaiah - San Diego CA, US
Richard Wu - San Diego CA, US

International Classification:

A61M 5/168
G16H 20/17
G16H 40/67

Abstract:

A method for tracking dose pattern and patient response may include determining, based at least on one or more dose events at a pump configured to deliver a medication to a patient, a dose pattern for delivering the medication to the patient. One or more vital signs associated with the patient may be received from a patient monitor. A presence of one or more anomalies may be determined based at least on the dose pattern at the pump and the one or more vital signs of the patient. An electronic alert may be sent to a mobile device in response to determining the presence of the one or more anomalies. Related methods and articles of manufacture, including apparatuses and computer program products, are also disclosed.
