Abstract

A device for monitoring the position of a plunger member slidingly engaged with a main body of a syringe includes a housing structured to be selectively coupled to the main body in a readily removable manner and a monitoring system disposed at least partially on or in the housing. The monitoring system is structured to detect the absolute position of the plunger member with respect to the main body in a manner which does not require any mechanical linkage with the plunger member.

Claims

1. A device for monitoring the position of a plunger member slidingly engaged with a main body of a syringe, the device comprising:

a housing structured to be selectively coupled to the main body in a readily removable manner; and

a monitoring system disposed at least partially on or in the housing, the monitoring system being structured to detect the absolute position of the plunger member with respect to the main body in a manner which does not require any mechanical linkage with the plunger member.

2. The device of claim 1, wherein the monitoring system is structured to detect the absolute position of the plunger member with respect to the main body by determining an amount of light transmitted through a portion of the plunger member.

3. The device of claim 1, wherein the monitoring system comprises:

a source of electrical power;

a sensing system structured to detect the absolute position of the plunger member with respect to the main body;

a processing device electrically coupled to the sensing system and the source of electrical power; and

a transmitting device electrically coupled to the processing device, the transmitting device being structured to transmit information received from the processing device.

4. The device of claim 1, wherein:

the housing comprises a protruding portion which is structured to overhang an opening at a first end of the main body;

the protruding portion includes a groove defined therein which is structured to receive a portion of the plunger member; and

the sensing system comprises;

an optical emitter disposed on a first side of the groove, and

an optical detector disposed on a second side of the groove opposite the first side.

5. The device of claim 1, wherein the processing device and the transmitting device are integral portions of a single device.

6. The device of claim 1, wherein the source of electrical power comprises a rechargeable battery.

7. The device of claim 1, wherein the housing comprises a number of resilient arcuate members which extend therefrom in a manner which is structured to selectively couple the housing to the main body.

8. The device of claim 1, further comprising an elongated planar sheet of material sized and structured to be coupled to a portion of the plunger member, the material having a transparency which varies in a predetermined manner along the length thereof.

9. A monitoring system comprising:

a device as recited in claim 1; and

a receiving device structured to receive the data transmitted by the transmitting device.

10. The monitoring system of claim 9 wherein the receiving device comprises:

a processor; and

a display,

wherein the processor is structured to;

receive real-time data from the device,

compute from the received data parameters of an injection including, but not limited to;

start time, end time, a time-varying volume curve, a time-varying rate curve and an identity of an administered drug, and

display one or more of the parameters via a graphical user interface.

11. A plunger member for use with a main body of a syringe, the plunger member comprising:

a first end having an elastomeric member structured to slidingly engage an internal passage of the main body;

a second end disposed opposite the first end and structured to be engaged by a user of the syringe; and

a number of generally planar rib members extending between the first end and the second end,

wherein one of the rib members comprises a gradient portion extending generally along the length thereof, and

wherein the gradient portion has a transparency which varies in a predetermined manner along the length thereof.

12. The plunger member of claim 11, wherein the gradient portion is formed in or on a sheet-like piece of material coupled to an exterior surface of the rib member.

13. The plunger member of claim 11, wherein the gradient portion is integrally formed as a portion of the rib member.

14. A system comprising:

a syringe comprising;

a main body, and

a plunger member slidingly engaged with the main body, the plunger member comprising;

a first end having an elastomeric member structured to slidingly engage an internal passage of the main body;

a second end disposed opposite the first end and structured to be engaged by a user of the syringe; and

a number of generally planar rib members extending between the first end and the second end, wherein one of the rib members comprises a gradient portion extending generally along the length thereof, the gradient portion having a transparency which varies in a predetermined manner along the length thereof; and

a device for monitoring the position of the plunger member with respect to the main body, the device comprising;

a housing structured to be selectively coupled to the main body; and

a monitoring system disposed at least partially on or in the housing, the monitoring system being structured to detect the absolute position of the plunger member with respect to the main body by determining an amount of light transmitted through the gradient portion.

15. The system of claim 14, wherein:

the housing comprises a protruding portion which is structured to overhang an opening at a first end of the main body;

the protruding portion includes a groove defined therein having a portion of the gradient portion disposed therein; and

the monitoring system comprises;

a source of electrical power;

a sensing system comprising;

an optical emitter disposed on a first side of the groove, and

an optical detector disposed on a second side of the groove opposite the first side;

a processing device electrically coupled to the sensing system and the source of electrical power; and

a transmitting device electrically coupled to the processing device, the transmitting device being structured to transmit information received from the processing device.

16. The system of claim 15, wherein the housing comprises a number of resilient arcuate members which extend therefrom in a manner which is structured to selectively couple the housing to the main body.
