Below I will introduce the most popular Jiangsu Ruifeng brand insulation detector on the market, and take it as an example to introduce its usage in detail.
The above picture shows Jiangsu Ruifeng brand YC- 10KJ-A hospital supply room dedicated insulation detector. The appearance of this insulation detector is simple and bright, beautiful and generous, which is very suitable for the environment of operating room and supply room. Let me tell you how to use it:
First of all, the following is the host equipment part of the insulation detector.
The operation interface of the host part is described as follows:
The following are common auxiliary tools for insulation detectors:
The following are the auxiliary tools of insulation detector:
1 is the ring probe of insulation detector, 2 is the commonly used brush probe, 3 and 4 are the commonly used needle probes, the front end is needle-shaped, and parts 5, 6 and 7, that is, red line 7 is the high voltage line, green line 6 is the conductive line, and black line 5 is the ground line. The black and green ones are crocodile clips.
Second, the insulation detector equipment connection:
? First, we insert the red wire 7 into the red high voltage port at the upper right of the host, the green wire 6 into the green conduction port on the right side of the main surface, and the black wire 5 into the ground port of the host. 8 crocodile clips: the other end of the black line 5 is connected with the corresponding black crocodile clip, and the other end of the green line 6 is connected with the green crocodile clip.
The picture above shows the unipolar electrotome commonly used in hospitals. We will use this commonly used monopolar electrotome to demonstrate the conduction detection of insulation detector:
A, insulation detector conductivity test:
First, turn on the power switch in the lower left corner of the machine, as shown in the figure:
? The knob in the middle of the lower row of the machine has two gears. Turn one gear clockwise, then turn to the insulation gear, and turn to the on gear counterclockwise. First, clamp the black crocodile on the metal end of the monopolar electrotome, and then clamp the green crocodile on the other metal working end of the monopolar electrotome, as shown in the figure:
? At this time, the resistance of the display screen of the host computer is displayed as 0, and there is a dripping reminder sound, indicating that both ends of the electrotome are conductive. If the electrosurgical unit is non-conductive, the display screen of the main unit does not change, and the resistance value is not 0, but infinite.
Second, the insulation detector insulation performance testing
The concept of insulation detector insulation refers to the voltage applied to the insulation layer of surgical instruments, because it should be said that different voltages applied to the same insulation layer have different insulation properties. So what standard do we use to test the insulation performance? It should be tested with the highest working voltage of the instrument. Now let's test the insulation performance of unipolar electrotome.
Assuming that the maximum working voltage of this monopolar electrotome is 2000V, we clamp the black crocodile on the metal end of the electrotome, adjust the output voltage at the lower right corner of the main engine to 2.0KV, and check the insulation layer on the surface of the electrotome with a brush probe. If the display value of the host computer does not change and the surface of the electrotome instrument does not respond, it means that the insulation performance of this instrument is intact and qualified below 2KV.
Similarly, assuming that the highest working voltage of the electrotome is 5KV, we adjust the value of the middle knob to 5KV, and brush the surface insulation layer of the electrotome with a brush probe. At this time, it will be very obvious that there will be several small leakage points on the surface of the electrotome insulation layer, as shown in the following figure:
This shows that the insulation performance of the same electrotome is unqualified under the working voltage of 5KV. That is to say, at 5KV, it is an instrument with unqualified insulation performance. This unqualified instrument will do harm to the patient's health.
At this point, the insulation performance test demonstration is over.
Summary: Through the performance test of the insulation detector, we concluded that the insulation performance test must be carried out at the highest working voltage of the instrument. Our insulation detector is suitable for all instruments. We set the output voltage of the machine to 0- 10 kV (that is, 0- 10KV), which is consistent with the charged voltage of all charged instruments in the market. The output current of our insulation detector is not higher than 0. 1mA, which ensures the personal safety of operators to the maximum extent. The safe current of human body is.
