Illustration of the use of insulation tester

After the introduction of the new supply room management specification, insulation tester products become one of the groups of hospital sterilization supply room center must be equipped with products, the correct use of hospital insulation tester, not only to protect the operator's personal safety, improve work efficiency, but also effectively prevent the patient in the operation by the electrified instruments burned to reduce the occurrence of medical errors.

Here I will introduce the market's most popular Jiangsu Ruifeng brand insulation tester as an example of the detailed introduction of his method of use

The picture above is Jiangsu Ruifeng brand YC-10KJ-A hospital supply room insulation tester, this insulation tester appearance is simple and clear, beautiful and generous, and the operating room and the supply room environment is very with the following I am operating.

First of all, the following is the host equipment part of the insulation tester

The operation interface of the host part is described as follows:

The following is the commonly used auxiliary tools of the insulation tester:

Let's introduce the auxiliary tools of the insulation tester:

1 is the ring probe of the insulation tester,

1 is the ring probe of the insulation tester. Detector ring probe, 2 is commonly used brush probe, 3, 4 for the commonly used needle probe, the front end of the pull-out has a needle shape, 5, 6, 7 part of the red line that is 7 for the high-voltage line, 6 green for the conductor line, 5 black is the ground line. 8 black and green is the crocodile clips.

Second, the insulation detector equipment connected to use:

? First of all, we will insert the red line 7 to the host of the upper right red high-voltage port, the green line 6 inserted into the main side of the right green conduction port, black line 5 inserted into the host of the ground port. 8 part of the crocodile clips: the corresponding black crocodile clips connected to the other end of the black line 5, green crocodile clips connected to the other end of the green line 6.

The above figure for the hospital commonly used unipolar electric knife, we use this commonly used unipolar electric knife to give you a demonstration of the insulation tester conductivity testing:

First, insulation tester conductivity testing:

First of all, the machine's lower-left corner of the power switch is open, as shown in the figure:

? Machine under the row of the center knob, there are two gears, clockwise rotation of a gear and adjusted to the top for the insulation gear, counterclockwise screwed to the end of the on-stream gear, first of all, with a black crocodile clips clip to the metal end of the unipolar cutter, green crocodile clips to the unipolar cutter to the other metal end of the work: as shown in Figure:

? At this time the host display resistance value shows 0, and there is a drip reminder sound, which indicates that the two ends of the electric knife is on. If the electric knife does not lead, the host display is not any change, the resistance value is not 0, but infinity.

Second, insulation tester insulation testing

Insulation tester insulation this concept refers to the voltage applied to the insulating layer of surgical instruments, because it should be said that different voltages added to the same insulating layer above his insulation is different. So what kind of standard do we use to test the insulation performance? Should be the highest working voltage of the device to detect, now we test the insulation performance of the unipolar knife test,

Assuming that the highest working voltage of the unipolar knife is 2000V, we will be black crocodile clips clamped to the metal end of the knife, and the host of the lower-right corner of the output voltage is set to 2.0KV with a brush probe to check the surface of the knife's insulating layer, if the host of the display values If the host display value does not have any change, and there is no reaction on the surface of the electric knife instrument, which indicates that the insulation of the instrument is intact and qualified below 2KV.

Similarly, assuming that the maximum working voltage of the knife is 5KV, we will be the middle of the knob value to 5KV, through the brush-type probe brush through the knife surface insulation, it will be very obvious in the knife insulation surface will have a number of small leakage points, as follows:

This shows that the same knife in the 5KV this working voltage, his insulation performance is not qualified. That is to say, at 5KV, this is an unqualified device. This unqualified device will cause damage to the patient's body.

This is the end of the insulation testing demonstration.

Summary: Through the insulation tester performance testing test, we summarize the instructions: if you want to correctly conduct insulation testing, must be in the device under the highest working voltage testing. Our insulation tester is to adapt to all the equipment testing, we will set the output voltage of the machine for 0-10KV (that is, 0-10,000 volts), which is in line with the market, including all the charged equipment charged voltage, and we have this insulation tester's output current is not higher than 0.1mA, the maximum guaranteed operator's personal safety, the human body's safe current is The safety current of human body is 10mA, not more than 0.1mA current through the body, will not cause any damage to the human body.
