What is medical PCB?

HealthcarePCB manufacturer  talk A PCB is a type of electronic that comprises insulating material between two sheets of conductors. This can take the form of flexible or rigid boards and there are many uses for this including electrical equipment such as computers, remote controls, and calculators.

However, what we will be focussing on here is medical PCB (or medical printed circuit board). That means any types of PCB used within the medical industry which include: cardiac monitors; implantable pacemakers; defibrillators; ventricular assist devices; neurostimulators; cochlear implants; drug infusion pumps and insulin pumps. These devices use various sized circuits to perform their function and generally, these are very small, with most being the size of a thumbnail or smaller.

 

Types of Medical PCBs

PCBmanufacturerChina  talk there are many different types of Medical PCBs. And these can broadly classify into two main categories: high voltage and low voltage boards.

 

1. High Voltage Medical PCB:

High voltage printed circuit boards that monitor electrical pulses or shocks from a defibrillator or monitor heart activity that has a high voltage of 400 V to 450 V and low current on the order of 100mA-300mA. The size for this type of printed circuit board is bigger than other types.

 

2. Low Voltage Medical PCB:

Low voltage printed boards are those with a small power source such as batteries. Which provide intermittent charging for up to 10 years on the order of 3 V, 5V, 9V-12V, and 24V. The size for this type of medical printed circuit board is smaller than the high voltage printed circuit boards category. There are two kinds of low voltage circuits based on the mechanism.


 

How are medical PCB used?

In order to understand how printed circuit boards function within a specific type of electronic device, you need some basic knowledge of how the device works. So, let’s look at an example to clarify this. There are many medical devices that use a cardiac monitor as part of their function and one of those is a defibrillator.

 

 

How does a Defibrillator work?

A defibrillator can design to deliver an electrical shock through electrodes attached to the skin in order to restore heart rhythm back into a normal sinus rhythm following a sudden loss of this vital organ function due to fibrillation.

 

1) Firstly

Two patches with gel-covered wires. It can insert through the upper chest area into the veins on either side of your heart. These electrodes record the electrical impulses of your heart’s activity. This allows your doctor to determine how fast your heart beats and whether you need an electric shock. Leads are attached to the electrodes so that electricity can flow through them into your body.

 

2) Second

A screen that monitors the heart activity will display this information for the physician to see. It can also record on the computer to analyze later if necessary.

 

3) Three

PCBsupplier  talk Physicians can choose to perform either synchronized cardioversion or defibrillation procedures. These procedures use electricity from the defibrillator circuitry to achieve their purpose. In both cases, two patches will place on your skin. However, depending on the type of treatment decided upon, an external device may also be part of the procedure.
