Patent number: 12186072Abstract: Techniques for quantifying respiration using a wearable device are described. According to some aspects, a wearable device includes multiple thermal sensors thermally coupled to one or more heat spreaders. The wearable device may in some cases be small enough to be wearable between the mouth and nose of the patient, such as via an adhesive attachment to the upper lip. When the patient exhales, air is produced through the mouth and/or through the nose. Each heat spreader may absorb heat of exhaled air which may thermally propagate to a thermal sensor coupled to the heat spreader. By measuring the change in temperature over time measured by the thermal sensors, measures of respiration such as respiratory rate, minute volume and/or tidal volume of the patient may be determined. Such measures may be determined by the wearable device or by an external device to which data is transmitted.Type: GrantFiled: January 11, 2019Date of Patent: January 7, 2025Assignees: Pontificia Universidad Católica de Chile, Fundación Copec Universidad CatólicaInventors: Daniel Hurtado, Angel Abusleme, Javier Chavez

Patent number: 11746387Abstract: The invention aims at a non-invasive method of early diagnosis of gastric cancer, using as a biomarker the levels of methylation of the DNA sequence of the promoter of the Reprimo-like gene in plasma. The inventors have established the utility of Reprimo-like as a biomarker, and especially as a biomarker for the early detection of gastric cancer, since they have determined that Reprimo-like is consistently silenced in gastric cancer, both in incipient and advanced stages. This silencing is given by methylation of its promoter region, which is detectable in plasma samples, allowing us to measure it as a liquid biopsy in a non-invasive, fast and inexpensive way.Type: GrantFiled: June 20, 2018Date of Patent: September 5, 2023Assignee: Pontificia Universidad Catolica de ChileInventors: Alejandro Corvalán, Alejandra Alarcón
