Benefits of technology
The present patent is about a plunger head for a medication injection device. The plunger head has two components: one holds electronic components and the other connects to it to form the plunger head. When the plunger head is installed in the device, the second component separates the first component from the medication. The technical effect is to provide a plunger head that protects the electronic components while still allowing them to be used in the medication injection device.
Problems solved by technology
Currently, there are a limited number of methods or devices for automatically tracking the drug administration without requiring the user to manually measure and record the volume, date, and time.
A smaller portion of the market is composed of reusable pens which are more expensive, and still don't include good dosage tracking capabilities.

Embodiment Construction
[0020]Reference will now be made in detail to embodiments of the present disclosure, examples of which are illustrated in the accompanying drawings. Where possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.
[0021]FIG. 1 shows a perspective view of a medication injection device in the form of a syringe 10 designed for ejecting a fluid. Syringe 10 may include a barrel 12, a plunger 14, a needle 16, and a hub 18 connecting needle 16 to barrel 12. Barrel 12 may be configured to contain a fluid, for example, a medication 20 and syringe 10 may be configured to dispense medication 20 from needle 16 when plunger 14 is depressed. A standard syringe usually contains a plunger head at the end of the plunger that seals the top of the barrel and forces the fluid out the needle when the plunger is depressed. The plunger head for a standard syringe is usually just a piece of molded rubber.
[0022]For syringe 10 shown in FIG. 1, the standard pl...

Abstract
A method of tracking injections includes depressing a plunger of a medication injection device, and sending and receiving ultrasonic signals from a plunger head installed within a barrel of the medical injection device. The method also includes measuring a time of flight for the signals to travel through the medication, and determining a position of the plunger head based on the time of flight of the signals. Additionally, a plurality of data samples representative of the position of the plunger are logged, and a distance the plunger head travels is calculated. This is used to calculate the quantity of the medication dispensed based on the distance the plunger head travels. An external device is then used to back-interpolate a time corresponding to each data sample logged in order to determine the time the quantity of medication was dispensed.
Description
RELATED APPLICATIONS[0001]This application claims the benefit of U.S. Provisional Application No. 62 / 329,605, filed Apr. 29, 2016, which is incorporated by reference in its entirety.BACKGROUNDTechnical Field[0002]The present disclosure relates generally to the field of tracking the administration of medication, and more particularly, apparatus and methods for tracking the administration of medication by medication injection devices.Background Description[0003]Measuring the quantity and recording the timing of a drug's administration is an integral part of many disease treatments. For many treatments, to achieve the best therapeutic effect, specific quantities of a drug may need to be injected specific times of day. For example, individuals suffering from diabetes may be required to inject themselves regularly throughout the day in response to measurements of their blood glucose. The frequency and volume of insulin injections must be carefully tracked and controlled to keep the patie...
