Embodiment 1

[0053] figure 1 A structural block diagram of a medical low-temperature plasma sterilizer power supply provided in Example 1, its structure is as follows:

[0054] The power supply mainly includes a main power circuit and a control circuit. The main power circuit includes: a pre-stabilizing circuit 101, a filter circuit 102, a switching inverter circuit 103, and a step-up transformer 104. The control circuit includes: a control unit 2 . The current transformer 3 , wherein the power supply device of the control unit 2 includes: a power filter 201 , a step-down transformer 202 , a rectification and filtering circuit 203 , and a series voltage stabilization circuit 204 . Wherein, the pre-stabilizing circuit 101 is connected to the 220VAC AC mains 8, the filter circuit 102 is connected to the pre-stabilizing circuit 101, the switch inverter circuit 103 is connected to the filter circuit 102, and the step-up transformer 104 is connected to the switch inverter Transformation circui...

Embodiment 2

[0064] figure 2 It is a structural block diagram of a medical low-temperature plasma sterilizer power supply provided in Embodiment 2.

[0065] Such as figure 2 As shown, the difference between this embodiment and Embodiment 1 is that a state current transformer 4 is also provided at the output end of the switch inverter circuit 103, and the state current transformer 4 is connected to a working state detector 5, used to obtain the current value output by the switch inverter circuit 103 and feed it back to the working state detector 5; the working state detector 5 outputs a power supply working state signal according to the current value obtained by the state current transformer 4 , as the control feedback signal of other units of the medical low-temperature plasma sterilizer; when the current value read by the working state detector 5 is greater than a certain value, it can be determined that it is in the working state, and a high level signal can be output at this time or ...

Embodiment 3

[0067] image 3 A structural block diagram of a medical low-temperature plasma sterilizer power supply provided in Embodiment 3.

[0068] Such as image 3 As shown, the difference between this embodiment and Embodiment 2 is that an ammeter 7 is arranged in series at the output end of the pre-stabilization circuit 101 to display the current value output by the pre-stabilization circuit 101 . Then, during mass production, workers can adjust by looking at the indication of the ammeter, the operability is greatly improved, and of course the production efficiency can also be improved. Moreover, in the production process, it is not necessary to disconnect and reconnect the output end of the pre-stabilizing circuit 101 in order to set up the ammeter, so the operation is more convenient. At the same time, it is also convenient for maintenance in the future use process.

Abstract

The invention relates to a pulse current source, in particular to a current source of a medical low-temperature plasma sterilizer, and belongs to the technical field of power supplies. The current source mainly comprises a main power loop and a control loop, wherein the main power loop comprises a voltage pre-stabilizing circuit 101, a filter circuit 102, a switch inverter circuit 103 and a booster transformer 104; and the control loop comprises a control unit 2 and a current transformer 3. The current source is applied to the production process of the medical low-temperature plasma sterilizer, thus the traditional method for adjusting the distance between the discharging grid and the discharging electrode or the mode of electrolyte in the sterilization cavity is changed, and the output voltage of the voltage pre-stabilizing circuit 101 and the output voltage of the switch inverter circuit 103 are adjusted to achieve the purpose of quickly adjusting the medical low-temperature plasma sterilizer to discharge normally. Therefore, by using the current source disclosed by the invention, the production efficiency of the medical low-temperature plasma sterilizer can be greatly improved; in addition, the medical low-temperature plasma sterilizer can also be more durable.

Description

technical field [0001] The invention relates to a pulse current source, in particular to a current source used in a medical low-temperature plasma sterilizer, and belongs to the technical field of power supplies. Background technique [0002] With the rapid development of medical technology and high technology, more and more surgical instruments are used in surgery, and many surgical instruments cannot withstand high temperature steam sterilization. At present, ethylene oxide sterilization and glutaraldehyde immersion disinfection methods are commonly used to sterilize surgical instruments that cannot withstand high temperatures. This method has disadvantages such as long sterilization cycle, toxicity, and environmental pollution. [0003] The birth of the medical low-temperature plasma sterilizer has solved the above problems. It has the advantages of low temperature, dryness, speed, and non-toxicity, and has been gradually used by some large-scale medical institutions in ...
