Doctor from Himachal Pradesh Receives U.S. Patent for Device Designed to Assist in Treating Critically Ill Patients

According to the doctor, this invention will enable continuous measurement of dozens of blood molecules and ion levels, providing real-time results without losing even a single drop of the patient’s blood.

Dr. Bal Chander, a professor of pathology at Dr. Rajendra Prasad Medical College in Kangra district, Himachal Pradesh, has been granted a U.S. patent for developing a “Blood Analysis System.” The device is specifically designed to assist in real-time monitoring and treatment of critically ill patients.

Dr. Chander shared that the untimely passing of his teacher and a school friend inspired this project, which he completed within a year without any external funding, sponsorship, or collaboration.

In a certificate issued by Acting Director Koc Morgan Stewart of the United States Patent and Trademark Office, it was stated: “The Director of the United States Patent and Trademark Office has received an application for a patent for a new and useful invention. The title and description of the invention are attached. The requirements of the law have been met, and it has been determined that this invention is eligible for a patent under patent laws.”

Dr. Chander added that the European Patent Office has also confirmed the uniqueness, functionality, and components of the invention.

He explained that the BAS (Blood Analysis System) relates to the concept and design of a new medical device aimed at critically ill patients in intensive care units (ICUs) as well as other patients requiring close monitoring.

“This system detects various critical data points and dynamically adjusts treatment according to the patient’s needs,” he said.

Dr. Chander further explained, “This invention will make it possible to continuously measure dozens of blood molecules and ions and display real-time results without losing even a drop of the patient’s blood.”

Currently, blood samples are repeatedly drawn from patients and sent to laboratories to test levels of glucose, lactate, urea, creatinine, bilirubin, sodium, potassium, and other markers. The process can take over an hour to yield results—an unacceptably long duration for critically ill patients, he said.

“These test results are essentially snapshots of a constantly changing blood profile,” he added. “Trying to interpret a patient’s condition based on a few snapshots is like trying to understand an entire three-hour film from a handful of still images.”

Moreover, the BAS has been designed to regulate dozens of blood molecules and ion levels simultaneously in a highly controlled and selective manner—without using drugs.

Unlike dialysis, which indiscriminately filters out substances from the blood, this invention can selectively adjust specific molecules without removing others. The adjustments can be monitored in real time.

Dr. Chander reiterated that the motivation for this invention stemmed from the loss of his mentor and a fellow student at Sainik School Sujanpur Tihra. Initially, the project aimed solely to measure the levels of hundreds of blood molecules and ions to understand the causes of death, but it eventually evolved into a system capable of both analyzing and correcting imbalances.

A native of Shimla and an alumnus of Sainik School Sujanpur Tihra, Dr. Chander completed his MBBS and MD (Pathology) from AIIMS, New Delhi.
