Abstract

Device for monitoring the administration of medication in a syringe that in one embodiment comprises a support element provided with a housing for a port access for coupling the syringe, said port access, when arranged in the housing, defining a longitudinal axis corresponding to the coupling direction and a transversal plane perpendicular to said axis and which passes through the port access. One or more cameras arranged in the support element that encompass in its/their visual fields the cylinder of the syringe when the syringe is coupled to the port access. The one or more cameras are placed within said plane, the optical axes of the one or more cameras intersecting said longitudinal axis, the support element and the one or more cameras do not overlap with the cylinder of the syringe in the direction defined by said longitudinal axis when the syringe is coupled to the port access.

Claims

1. A device for monitoring the manual administration of medication included in a syringe, comprising:

a support element provided with a housing for a port access for coupling the syringe, said port access, when arranged in the housing, defining a longitudinal axis corresponding to the coupling direction and a transversal plane perpendicular to said axis and which passes through the port access;

one or more cameras arranged in the support element to encompass in its or their visual fields the cylinder of the syringe when the syringe is coupled to the port access;

said one or more cameras are placed in the vicinity of said plane;

the optical axis of said one or more cameras intersecting said longitudinal axis;

the support element and said one or more cameras does not overlap with the cylinder of the syringe in the direction defined by said longitudinal axis when the syringe is coupled to the port access;

thus allowing a free visual and manual access to the syringe cylinder when the syringe is coupled to the port access.

2. The device according to claim 1, wherein said housing comprises means for clipping the port access.

3. The device according to claim 1, which comprises means for processing the images obtained by said one or more cameras enabling identifying a label placed on the syringe and/or determining the volume of medication administered via the syringe by detecting the syringe position and size, estimating the embolus position and computing the difference between the beginning of the operation and the end of the operation.

4. The device according to claim 1, wherein the port access is located in the center of the support element.

5. The device according to claim 1, wherein the support element has a U-shape, said port access being placed in the centre of the U-shape body.

6. The device according to claim 5, wherein the housing is arranged to house an outlet port arranged perpendicular to the longitudinal axis and intended to be coupled to an administering tube.

7. The device according to claim 1, wherein the support element is a parallelepiped shaped body provided with a central transversal channel which divides the support element in two lateral halves, each lateral half having at least one camera, the port access being placed at the center of said transversal channel.

8. The device according to claim 7, wherein the support comprises two outlets below, each one oriented along said transversal channel, the channel being able to accommodate the port access and the ends of two tubes.

9. The device according to claim 1, wherein said one or more cameras are placed at most 20 cm from the port access, more preferably at most 4 cm from the port access, even more preferably at most 2 cm from the port access.

10. The device according to claim 3, wherein said means for processing images is a microprocessor optionally included in said device.

11. The device according to claim 3, wherein the label is a QR code, a 2D bar code, a datamatrix or printed letters or the label is a Radio Frequency Identification label and the device further comprises a receptor of radio frequencies incorporated.

12. The device according to claim 1, wherein said one or more cameras comprise a CCD optical sensor and a lens and preferably polarizing or antireflection filters.

13. The device according to claim 12, wherein the CCD is placed parallel to the transversal plane and the lens are oblique to the CCD plane such that the optical axis of the one or more cameras intersect said longitudinal axis;

14. A method for monitoring the manual administration of medication, comprising the steps of:

a) Acquisition of a video stream from each camera of the device according to claim 1;

b) Identification of the label of the container, the position and size of the piston and the container;

c) Computing the movement of the piston in order to deliver the desired amount of medication.

15. A method according to claim 14, further comprising the step of:

d) Transmitting the information to a screen or other human interface and to the hospital data base.

16. A device for monitoring a manually operated syringe, the syringe comprising a dispensing tip, a syringe barrel with a syringe barrel axis and a syringe plunger, the device comprising:

a basis adapted to be connected to a medication administration point of a patient and comprising a syringe insertion port adapted to receive the syringe dispensing tip, the basis being configured such that when the syringe is inserted in the insertion port the syringe barrel is not in direct contact with the basis, and at least part of the syringe barrel projects from the basis in the direction of the barrel axis, and

an image acquisition system arranged on the basis and adapted to capture an image of at least part of the syringe plunger when the syringe is inserted in the insertion port.
