Medical robots are already being used worldwide to perform or assist with surgical procedures. Robots will assume more and more responsibility in the future.
FREMONT, CA: An invasive medical device is an instrument or device inserted temporarily or permanently into the patient's body. Invasive medical devices are used for several specific functions; however, they can usually be classified as either internal monitoring activity, interacting with or assisting internal organs, or replacing internal organ functionality. In addition, invasive medical devices are possibly class 2 or class 3, indicating they cause some risk to the patient. Thus, the essential factor in developing invasive medical devices is safety. Therefore, each stage of the development process is guided by minimizing the potential threat to patients using them. Below are some of the common invasive medical device applications listed.
Urinary catheters: They are rubber or silicone tubes inserted through the urethra and into the bladder. Immediately after the catheter is in the bladder, a small bag at the catheter's tip is inflated to prevent it from sliding back out. Next, the catheter drains the urine into a load connected to the other end. Occasionally, a physician order a single catheterization. The catheter is inserted briefly to allow urine to flow from the bladder and then removed. While this single catheterization is less likely to cause infection, it is more inconvenient for patients whose doctors need to ensure that all urine has been collected and measured.
Intravenous lines: IVs are used to supply fluids, medicines, and blood products directly into the bloodstream. First, a thin, small catheter is inserted into a vein, most frequently in hand or lower arm. This catheter is fastened to plastic tubing, which is connected to a fluid bag. In some instances, the catheter is not immediately connected to the tubing but sealed with a cap. If IV fluid or medication is required later, the cap is removed, and the tubing is connected.
Central lines: Central venous catheters are similar to PICC lines but usually implanted in the chest or neck into a large vein. They also stay for more extended periods. Also, these lines are long enough to reach pivotal veins. They can do the same things as a PICC line while patients are in hospital, but they can’t be left when a patient goes home. Central lines are the IV catheters most likely to get infected, so doctors only use them when necessary.
Endotracheal tubes: It is a semi-rigid tube inserted into the trachea, most often through the mouth. The tube is linked to a ventilator, a breathing machine. An endotracheal tube may be inserted and attached to an Ambu bag in an emergency, allowing medical staff to manually push air into the lungs until the patient is connected to a ventilator. If someone has an extended period on a ventilator, a surgeon may perfume a tracheotomy. This forms the endotracheal tube's throat opening.
