Description

Medical insulation detector device

Technical Field

The utility model relates to a detector specifically is a medical insulating detector device.

Background

The existing medical insulation detector needs to be operated by two hands, after the two hands wear insulation gloves, one hand holds an instrument to be detected, and the other hand holds a brush with high voltage to brush and sweep an electrical insulation part of the instrument to be detected, so that the damage condition of the insulation part of the instrument is detected. The disadvantage of this method is that the high voltage brush is exposed to high voltage, which is prone to cause unsafe factors, and although the operator wears the insulating gloves, the operator may be injured by electric shock if the insulating gloves are broken or the high voltage brush contacts other parts of the operator.

In addition, most of the existing medical insulation detectors are used for detecting direct current high voltage, and a current limiting device is designed in a circuit to protect the safety of an operator. The problem with this method of protection is that when the high voltage portion inadvertently contacts the operator, a portion of the current still passes through the body, which can be harmful to some more sensitive people.

The direct-current high-voltage detection environment is different from the real condition of the appliance, the electrically insulated appliance is used under the high-frequency alternating-current condition in use, and for some special appliance insulation layers, the direct-current insulation detection is not necessarily suitable for the alternating-current environment after being qualified.

Detailed Description

the technical solution of the present patent will be described in further detail with reference to the following embodiments.

The first embodiment is as follows: referring to fig. 1-2, a medical insulation detector device includes a detector main unit 3, the detector main unit 3 is connected to a negative connection wire 5 through a negative connection port 6, the end of the negative connection wire 5 is connected to a connection clip 4, the front side of the detector main unit 3 is connected to a first U-shaped groove 2 through a connection member 11, the front side of the first U-shaped groove 2 is fixedly connected to a second U-shaped groove 1, and the first U-shaped groove 2 and the second U-shaped groove 1 are respectively connected to a high-voltage output steel wire brush 10.

the top of the detector host 3 is electrically connected with a detector display screen 7.

the top of the detector main machine 3 is electrically connected with an adjusting knob 8.

And the first U-shaped groove 2 and the second U-shaped groove 1 are respectively connected with insulating protective sleeves 9 positioned at two sides of a high-voltage output steel wire brush 10.

Example two: this embodiment is a further improvement of the previous embodiment: first U type groove 2 is different with 1 size in second U type groove, and first U type groove 2 is less than second U type groove 1, and the U type groove of unidimensional can be suitable for the different apparatus that wait to detect, and increase detection application scope.

Further explanation is as follows: the utility model discloses also carry out intelligent design on the circuit, carry out human contact detection to the apparatus earlier before applying high voltage to the detection instrument, if the instrument detects that there is the human body position to contact the electrically conductive testing section of apparatus, the instrument will not export detection voltage to send out the chimes of doom and indicate that the operator has incorrect contact to the detection instrument, notice safety. Therefore, an operator can be better protected, and during detection, the instrument can simulate the real working environment of the instrument according to the working environment characteristics of different instruments, apply high-frequency alternating current detection high voltage with the same frequency as the working environment of the instrument to be detected, and simultaneously apply pulse direct current high voltage for detection as required, so that the reliability of the detection result of the detected instrument is ensured, and the insulation performance reduction or aging of the instrument can be prompted according to the detection results of the direct current high voltage and the high-frequency alternating current, so that a detector is reminded to prepare for instrument replacement.

The detection kit is specially designed to be composed of two detection grooves (a first U-shaped groove 2 and a second U-shaped groove 1) having a U-shaped structure. The exterior of the detection groove is surrounded by high-voltage resistant rubber to play an insulating role, and the interior of the detection groove is formed by a steel wire brush with a plurality of steel wires. The detection groove is inserted into the insertion opening of the detector through a connecting piece 11 and is connected and fixed with the detector main body 3. An operator holds the instrument to be detected with one hand, the negative connecting wire 5 and the connecting clip 4 of the detector are connected to the working electrode connecting part of the instrument to be detected, and the other end of the negative connecting wire 5 of the detector host 3 needs to be connected to the negative wire connecting port 6 of the detector host 3. When the detection operation is carried out, the instrument to be detected is inserted into the detection U-shaped groove. The detection device can be inserted into the U-shaped grooves with different sizes according to the size of the detected instrument, and then the instrument to be detected slides or is pulled back and forth in the U-shaped groove for detection. Before the instrument is started for detection, a human body contact detection circuit in the instrument is started in advance, the insulation detection instrument can intelligently judge whether a human body contacts the electrode part of the instrument to be detected or not according to the internal detection circuit, if the human body contacts the electrode part, an alarm occurs, a detection program is not operated, and related alarm contents are displayed on a display screen 7 of the detector. When the inspection instrument starts to operate the inspection program, the inspection instrument needs to first determine which part of the instrument to be inspected is in contact with the high-voltage output wire brush 10. Only when the insulation part of the instrument to be detected contacts the high-voltage output steel wire brush 10, the direct-current high voltage and the pulsating high voltage are automatically and intermittently started to carry out the insulation performance detection. Before the high voltage is detected, impedance detection is carried out (the impedance result is displayed on a detector display screen 7) so as to prevent the phenomenon of instantaneous short circuit and large current caused by the fact that the electrode part of the instrument to be detected enters into contact with the high voltage of the high-voltage output steel wire brush 10. When the high-voltage detection steel wire brush 10 contacts the insulation area of the instrument to be detected, high-frequency high-voltage alternating current detection voltage is output, meanwhile, direct current pulse high voltage is intermittently applied, all applied direct current and alternating current high voltage pulses are displayed on a display screen 7 of the detector, a control circuit in the instrument accurately controls all parameters, and the parameters of the detection current and voltage are monitored. When the high-voltage output steel brush 10 contacts the non-insulation area, the output of the detection voltage is stopped, the large current of the short circuit of the detection circuit is prevented, and the internal circuit of the instrument is protected. The whole circuit is intelligently controlled by the PIC singlechip, and two adjusting knobs 8 on the panel of the detector can be adjusted as required to adjust detection parameters so as to adapt to the detection requirements which cannot be met. Before each detection pulse is output, the impedance between the detection electrodes is detected, and the insulation area and the non-insulation area are distinguished. When the detection electrode is located in the non-insulation area, the CPU control circuit does not start the detection pulse so as to protect the internal circuit and the operator.
