What Does probe Mean
The term probe can refer to different classes of instruments and tools . These devices are linked to the verb probe : to conduct an investigation or a trace of something.
In the field of medicine , a probe is a device that is used to explore the cavities of the body or to carry certain substances into them. An example of these tubes are nasogastric tubes , which enter the body through the mouth or nose, pass through the esophagus and reach the stomach.
A catheter is also a tube. It is an elongated tube that is inserted into a vein or tissue to drain fluids or deliver drugs to the body . Among these catheters is the Nélaton catheter , which is used in the bladder to drain urine.
In addition to all the above, we can highlight that urinary catheters of this type have three fundamental elements: the body itself; the tip, which will become the part that is introduced into the patient's body, and the funnel, which is where the urine comes out and which is in relation to the collection bag.
Likewise, it should not be forgotten that this kind of probe can be classified according to different criteria:
-Based on the duration of the probing, it can be temporary, intermittent or permanent.
-Depending on their caliber and length, there are probes for children, for men and for women.
-Depending on the material of the catheter, we come across silicone probes, which are biocompatible and can last about 90 days; those made of latex, which are soft and last about 45 days; and the PVC ones, which are much more rigid.
A nautical probe , on the other hand, is a tool used to measure the distance between the hull of a ship and the seabed. There are different kinds of nautical sounders: among them echoic sounders , which carry out the measurement through ultrasonic signals.
Of course, it should not be overlooked that there are also probes in cars. Specifically, we are referring to the so-called lambda probe, which is located in the area of the exhaust pipe and whose mission is to measure the oxygen concentration in the exhaust gases. More specifically it is placed before what is the catalyst.
The first probe of this type that existed and to which it was shaped was the one developed by the German industry Bosch in the mid-1970s, specifically in 1976. A probe that was applied to the Volvo 240 car.
The space probes are machines that are launched into outer space for different types of scientific studies. These probes are directed towards objects or with a fixed direction to collect different kinds of data. The Voyager and Pioneer probes are examples of these probes.
The temperature probes and molecular probes are probes also contributing to the realization of various scientific work and enabling to perform different types of measurements .
