Choosing Chiller Pumps to Cool Medical Lasers
Posted in Bio-Medical, Manufacturing & Prototyping, Custom & Contract Manufacturing, Drug Delivery & Dispensing, Mechanical Components, Photonics, Lasers & Laser Systems, Medical, Drug Delivery & Fluid Handling, Briefs, MDB on Wednesday, May 01 2013

Medical lasers must be cooled either by premounted or portable chiller systems.

Laser systems continue to grow in application use throughout the medical industry. Applications for laser systems include diagnostic analysis systems, DNA sequencing systems, dental cleaning and surgery, skin care, eye surgery, tattoo removal, and much more. These systems commonly require cooling of the laser and other electronic components either by air flow on lower power laser systems, or by fluid circulation/chiller systems on higher power lasers. Higher power laser require an increased level of cooling capacity that results in systems that provide several gallons per minute of fluid circulation. This increased flow rate will maintain the laser and other electronics at the proper operating conditions.

Correct Catheter Placement in Children
Posted in Medical, Drug Delivery & Fluid Handling, News, MDB on Thursday, April 11 2013
A new study done at the Johns Hopkins Children’s Center, Baltimore, MD, described online in JAMA Pediatrics, show that in children catheters inserted in a vessel in the arm or leg and not threaded into a large vein near the heart are nearly four times as likely to dislodge, cause vein inflammation, or dangerous blood clots as are catheters advanced into major vessels near the heart. A peripherally inserted central venous catheter (PICC) placed into a small blood vessel, usually in the arm, and threaded toward a major blood vessel near the lungs and heart, is used as a temporary port for medications, nutrients, or fluids. However, clinicians sometimes leave the PICC line in a peripheral vein in the arm or leg instead, which, the researchers say, should only be done as a last resort.

Artificial Spleen to Treat Sepsis
Posted in Medical, Drug Delivery & Fluid Handling, News, MDB on Tuesday, April 09 2013
Researchers at the Wyss Institute for Biologically Inspired Engineering at Harvard University, Boston, MA, were awarded a $9.25 million contract from the Defense Advanced Research Projects Agency (DARPA) to further advance a blood-cleansing technology developed at the Institute with prior DARPA support, and help accelerate its translation to humans to treat bloodstream infections. In order to rapidly cleanse the blood of pathogens, the patient's blood is mixed with magnetic nanobeads coated with a genetically engineered version of a human blood 'opsonin' protein that binds to a wide variety of bacteria, fungi, viruses, parasites, and toxins. It flows through microchannels in the device where magnetic forces pull out the bead-bound pathogens without removing human blood cells, proteins, fluids, or electrolytes, similar to how a human spleen operates. The cleansed blood then flows back to the patient.

Wearable Artificial Lung Under Development
Posted in Implants & Prosthetics, Medical, Drug Delivery & Fluid Handling, News, MDB on Tuesday, April 02 2013
Researchers at the University of Pittsburgh, with the support of a $3.4 million National Institutes of Health grant, are working to develop an artificial lung to serve as a bridge to transplant or recovery in patients with acute and chronic lung failure. The project aims to develop a compact respiratory assist device called the Paracorporeal Ambulatory Assist Lung (PAAL), a wearable, fully integrated blood pump and lung designed to provide longer-term respiratory support up to three months while maintaining excellent blood compatibility. This is in sharp contrast to current long-term breathing support modalities, which include extracorporeal membrane oxygenation (EMCO)—a cardiac and respiratory technique in which blood is drained from the body, oxygenated, and the returned to the bloodstream, but can significantly limit a patient’s mobility and involve unwieldy equipment.

Bacteria Proven to Clog Devices Swiftly
Posted in Medical, Drug Delivery & Fluid Handling, News, MDB on Wednesday, March 13 2013
A new study by researchers at Princeton University, Princeton, NJ, examined how bacteria clogs medical devices, and found that the microbes join to create slimy ribbons that form tangles, trapping other bacteria, and creating a full blockage in a very short period of time. Their findings, they say, could help shape strategies to prevent clogging of devices such as stents. Using time-lapse imaging, they monitored fluid flow in a narrow tube similar to those used in medical stents with rough rather than smooth surfaces and pressure-driven fluid instead of non-moving fluid. The team of biologists and engineers placed a small number of bacteria that are common contaminants of medical devices into the tube and waited.

Managing Post-Traumatic Pain with Ultrasound Neuromodulation
Posted in Bio-Medical, Electronics, Treatment Devices, Medical, Drug Delivery & Fluid Handling, Briefs, MDB on Friday, March 01 2013

This ultrasound technique is an alternative to narcotics for treating pain from acute trauma.

The objective of this effort was to demonstrate the feasibility of using ultrasound induced neuromodulation (UNMOD) to manage pain. Pain management for acute trauma is generally accomplished with narcotics, which is less than ideal in a battlefield scenario. The technology of peripheral ultrasound neuromodulation (PUNMOD) offers several advantages over narcotics and current methods of neurostimulation. PUNMOD has the potential to be highly portable as a battlefield analgesic, and has the advantage of leaving the patient’s cognitive abilities intact. In addition, PUNMOD does not carry with it the risk of abuse or the need for the surveillance that is associated with pharmaceutical analgesics.

Valve–Based Printing of Human Organs
Posted in Drug Delivery & Dispensing, Medical, Drug Delivery & Fluid Handling, News, MDB on Tuesday, February 19 2013
A specialized 3D printing process, using human stem cells, could pave the way to building custom replacement organs for patients, eliminating the need for organ donation, immune system suppression, and possible transplant rejection. Sound fantastic? The new valve-based technique, developed by the biomedical microengineering group at Heriot-Watt University, Edinburgh, Scotland, in partnership with Roslin Cellab, a leading stem cell technology company, allowed the researchers to print delicate embryonic cell cultures, which can replicate indefinitely and differentiate into almost any cell type in the human body. The technique relies on an adjustable "microvalve" to build up layers of human embryonic stem cells (hESCs). Altering the nozzle diameter precisely controls the rate at which cells are dispensed.

Breast Pump Industry Booming; Can Supply Equal Demand?
Posted in Drug Delivery & Fluid Handling, News, MDB on Monday, February 18 2013
Tucked within the Affordable Care Act is a provision requiring insurance companies to cover breast pumps. Insurers must pay for the new benefit, but the law doesn’t specify whether insurers must cover certain brands or types of breast pumps. It directs health plans to pay for “the costs of renting breastfeeding equipment.” Some insurance companies have agreed to pay the costs of buying a personal pump, instead of renting a “hospital-grade unit, as the costs may be less. But, mothers scrambling to find the pump they want may have a difficult time, as demand has soared since the provision went into effect.
