Portable thermoelectric temperature regulator for elongated medicament containers

A portable housing with an elongated accommodating chamber that holds a medicament container such as a cartridge or syringe and uses thermoelectric elements to cool or heat a selectable partial region of the chamber. A control system adjusts which chamber section is temperature-regulated based on the piston position (filling level) detected by a sensor. Intended users are patients and caregivers who transport and dose temperature-sensitive medicaments.

(57) What the patent covered

This write-up was generated by AI from the patent's text and may contain mistakes, so check it against the original patent before relying on it.

The independent claim covers a housing with an elongated chamber, a thermoelectric temperature-regulating device whose plurality of thermoelectric elements extend only over a partial longitudinal area starting near the first end up to a mid-area, a control device that adjusts the temperature of that partial area in response to the piston position of the medicament container, and a filling level sensor that determines piston position.

Distinguishing feature: Temperature regulation is applied only to an adjustable partial longitudinal section of the chamber and is controlled according to the container piston (filling) position.

Novelty 3/5. Thermoelectric cooling of medicament carriers and shaped chambers were known; the novelty is localizing and dynamically adjusting which longitudinal section is actively temperature-regulated according to piston position.

Manufacturing

Injection-molded plastic housing, bonded or screw-mounted metal heat spreaders, mounted thermoelectric modules, soldered electrical connections, assembled with sensors and control electronics, final sealing and testing.

Materials: Plastic housing (ABS or polypropylene), Thermoelectric (Peltier) elements, bismuth telluride based, Aluminum or copper heat spreader/plates, Elastomeric or foam insulation (e.g., silicone, PU foam).

Manufacturability 4/5. Several molded parts, off-the-shelf thermoelectric modules and sensors, and PCB-based control require moderate assembly but no precision optics or bespoke microelectronics.

Market demand

Buyers: Patients transporting temperature-sensitive injectables.

Before manufacturing

No related continuation or divisional patents in force were found. Design patents, trademarks and unrelated patents may still cover the product.

Regulatory requirements for devices that store medicaments and battery-powered thermoelectric units (safety, temperature accuracy) and a crowded market for insulin travel cases.

Claim 1, as granted

1. A temperature-regulating apparatus for medicaments comprising: a housing with at least one accommodating chamber for a medicament container, wherein the accommodating chamber is elongated along a longitudinal extent between a first end and a second end opposite the first end; a thermoelectric temperature-regulating device, wherein the temperature-regulating device can temperature-regulate only a partial area of the accommodating chamber, the thermoelectric temperature-regulating device including a plurality of thermoelectric elements that are attached to the accommodating chamber along the longitudinal extent, the plurality of thermoelectric elements extending only over a partial area of the longitudinal extent starting at a location near the first end of the accommodating chamber up to a middle area located between the first end and the second end of the accommodating chamber; and a control device that is configured to adjust a temperature of the partial area of the accommodating chamber that is temperature-regulated in response to a position of a piston of the medicament container, the partial area being adjustable using the thermoelectric elements, wherein the temperature-regulating apparatus includes a filling level sensor for determining a filling level of the medicament container which corresponds to the position of the piston.
