Smart syringe with dose capture and app for smart phone

1 . A smart syringe system comprising:

a syringe comprising:

a body having a scale formed thereon, and

a plunger having a series of triangles formed thereon extending along a length parallel to a longitudinal axis of the plunger, such that a relative position of the plunger with respect to the body can be determined based on an optical comparison of relative positions of the scale and the series of triangle; and

an apparatus external to the syringe, the apparatus comprising:

an image capture device, and

a processor configured to analyze the image capture device and thereby determine a fill level of the syringe.

2 . The smart syringe system according to claim 1 , wherein the scale is printed on a barrel of the body of the syringe.

3 . The smart syringe system according to claim 1 , wherein each triangle of the series of triangles is arranged with a base oriented toward a first end of the plunger and a point oriented toward a second end of the plunger.

4 . The smart syringe system according to claim 1 , wherein the apparatus external to the syringe further comprises a memory storing software instructions, and wherein the processor is configured to execute the software instructions and thereby execute an application configured to cause the processor to display information regarding the fill level of the syringe.

5 . The smart syringe system according to claim 1 , wherein the apparatus external to the syringe is a mobile phone.

6 . A smart syringe system comprising:

a syringe comprising:

sensing means for sensing a dose administered to a patient, the sensing means comprising:

a threading on a plunger of the syringe, and

a linear-rotary converter configured to convert a movement of the threading in a linear direction of the longitudinal axis of the plunger into a rotary motion;

first communication means for transmitting data regarding the dose; and

an apparatus external to the syringe, the apparatus comprising second communication means for receiving the data regarding the dose, and a display for displaying information regarding the dose.

7 . The smart syringe according to claim 6 , wherein:

the first communication means comprises at least one of a near field communication (NFC) transmitter and a Bluetooth transmitter,

and the second communication means comprises at least one of an NFC receiver and a Bluetooth receiver.

8 . The smart syringe according to claim 6 , wherein the linear-rotary converter comprises a switch configured to detect a presence of the syringe and a magnet comprising a rotary encoder configured to detect a rotational movement.

9 . A method of a syringe system, the method comprising:

a linear-rotary converter of a syringe sensing a movement of threading on a plunger of the syringe, the movement in a linear direction of a longitudinal axis of the plunger;

the linear-rotary converter converting the movement into a rotary motion;

the syringe obtaining data regarding a dose administered to a patient based on the rotary motion;

the syringe transmitting the data to an external device;

the external device receiving the data;

a processor of the external device executing software instructions and thereby analyzing the data; and

the external device displaying information regarding to the dose.

10 . The method according to claim 9 , wherein

the syringe transmitting the data comprises transmitting the data via one or more of near field communication (NFC) and Bluetooth, and

the external device receiving the data comprises receiving the data via at least one of NFC and Bluetooth.
