International Classification:

A61N 130

US Classification:

604 20

Abstract:

This invention relates to development of an iontotherapeutic device for regulated transdermal systemic administration of ionizable pharmaceutical compounds. It also provides an iontotherapeutic process for transdermal administration of ionized pharmaceuticals, particularly those which are otherwise transdermally absorbed to a small degree or not all, such as peptide pharmaceuticals, for example, insulins. The invention also relates to unit dose forms, for example, those in which an ionized pharmaceutical is dispersed in a hydrophilic polymer. The unit dose is adapted to be assembled as part of the pharmaceutical reservoir electrode, so that the ionized pharmaceutical will be delivered transdermally and then be absorbed systemically when the iontotherapeutic device is in operation.

International Classification:

A61F 7/00

Abstract:

A wearable device includes a housing to encompass a portion of a body part, biometric sensors coupled to the housing, a controller coupled to the housing and biometric sensors, a communication channel for communicating with external devices and a temperature regulator to controllably adjust a temperature of the housing. The wearable device is configured to provide remote controlled heating and cooling of the body part. The wearable device may include an evaporative heat exchanger and a thermoelectric heat pump. The wearable device may provide means for dissipating heat through vaporization of a substance or using an advective flux and phase transition.

Appl. No.:

15/709422

Inventors:

John Tianci Li - Roslyn Heights NY, US

International Classification:

B01D 35/00
F16H 57/04
B01D 35/143
B01D 35/30
B01D 35/06

Abstract:

A canister based transmission filter system, which may be integrated into transmission reservoirs. The system features a filter in the shape of a cylinder or a polygonal prism, and a corresponding transmission filter receiver. The filter has a pleated filtration surface with an integrated magnet, and is inserted into the receiver without need of additional screws, clips, nor bolts. The receiver closes off transmission fluid flow when filter is being changed to prevent contamination of the surroundings, and opens when the filter is installed to allow for filtration. Filter may be quickly changed using only the L-pin provided, and locks itself in place during installation.

Inventors:

John Tianci Li - Roslyn Heights NY, US

International Classification:

F16H 57/04

Abstract:

An isochoric mechanism for changing transmission fluid composed of a box component, two bags, two valves, a board, plastic tubing, and two adapters. The mechanism ensures that the same amount of new transmission fluid is injected into the transmission system as the amount of old transmission fluid that is drained out of the transmission fluid reservoir. Mechanism is driven by gravity, and usage requires two supports that are of equal height, to support the body of the mechanism using the board component. Valves ensure that the system can be stored and reused. Automatically collects old transmission fluid for recycling, and upon return to the provider, the mechanism may be refilled with new transmission fluid.
