Portable medical device design requires more flexible component packaging

<

One of the biggest trends in the medical device industry is miniaturization, which is to develop smaller, more portable devices to meet the limited space of hospital and home health care spaces, enabling healthcare professionals to quickly and easily move devices from one patient to another. Where. Ventilator, diagnostic equipment, pumps and suction equipment are now being improved to accommodate this trend change. The development of the health care industry has made important contributions to the miniaturization of medical devices , especially in Europe and the United States, where they strive to convert patients from hospitalization to home care treatment as quickly as possible, while in home care treatment, portability is treated and used by patients. Equipment is vital, which helps them achieve the highest possible quality of life.

Device miniaturization is a challenge for medical device designers to not only reduce the size of their products, but also to design devices that enable a variety of configurations and care settings. As a result, sensor manufacturers are beginning to respond to the need for device miniaturization by offering flexible mounting options, smaller size, and integration of multiple sensor functions into a single package. In some cases, some sensors have even been used in fields not previously covered, such as surgical instruments.

The sensor platform offers a variety of mechanical interfaces, mounting options, package types, and I/O options, enabling medical device designers to choose the right interface for their applications while reducing cost and board space. For example, pressure sensors can be integrated into a variety of designs because they offer a variety of connections (port styles), package styles (DIP, SIP, surface mount), and output (analog or digital) options.

Flexible sensor package options

The sensor's flexible package style (including manifold mounting and cable assembly options) allows designers greater flexibility in placing sensors on printed circuit boards (PCBs), and it eliminates the need for pipes and associated connections. The use of the medical device makes the shape of the medical device smaller, the design is simpler, and the assembly is faster. Flexible mounting options also ensure that the sensor is accurately placed in the desired position, ie close to the patient or liquid medium (eg blood, chemicals or water) for accurate and highly accurate measurements.

Pressure Sensor

The ability of the sensor to be placed close to the patient is critical for many applications, such as accurate dialysate and venous pressure in dialysis applications. The pressure sensor must be able to accurately monitor the pressure of the dialysate and blood to ensure it is maintained within the set range.

This type of application requires sensors that are small and capable of withstanding liquid media. In many cases, sensors that are not compatible with liquid media require additional mounting components to protect it, increasing the size, cost, and complexity of the product. Liquid medium tolerance is particularly important when monitoring patient breathing because the sensors here must be able to withstand the patient's cough and exhaled moist air.

For example, Honeywell TruStability? The HSC/SSC board-mounted pressure sensor and the 26PC flow-through pressure sensor are in direct contact with the liquid and quickly feed back the dialysate pressure while filtering the dialysate used by the patient. These sensors also offer a variety of port options and package designs for dialyzer manufacturers.
