Description

Disposable device for disposable medical equipment {Apparatus for scrapping the throwaway medical goods}

The present invention relates to a disposal device of a disposable medical device for removing various needles and types of acupuncture needles that are used at home by general hospitals, acupuncture hospitals and individuals in the field immediately after use by a user.

In a complex modern society, many people use medical devices to treat their homes in hospitals due to injury or illness. Medical equipment used in this way should be reused through thorough disinfection and sterilization according to the infection of bacteria and pathogens.

However, medical devices that are difficult to sterilize or disinfect, such as various needles or herbal needles, are disposable that cannot be reused after use, so they are completely disposed of and treated by the careless doctors, nurses, or users. Should be prevented.

In addition, in the process of direct treatment of the needle, the sharpness of the needle may also cause the infection of intermediate handlers such as botanicals who treat the needle, and if it is buried in the ground, the needle may not corrode well. It's made of a material that doesn't leave the ground for a long time and pollutes the surrounding environment.

Therefore, the necessity of a device capable of completely sterilizing and pulverizing the needle having these various problems without going through the human hand is very high.

Due to this problem and necessity, Korean Laid-Open Patent Publication No. 2001-64588 electrically connects a circuit equipped with a power supply and a needle so that a passage current flows through the needle so that the needle generates ohmic heat. While being sterilized, the material is degraded and then removed or treated by mechanical friction.

However, Korean Laid-Open Patent Publication No. 2001-64588 has a disadvantage in that it is not only complicated in construction but also difficult to reduce volume by installing a motor or the like for removing or processing by mechanical friction for final processing.

Also. Korean Laid-Open Patent Publication No. 2002-79193 has a disadvantage of causing radio wave interference due to the use of electromagnetic waves because it is melted using a high frequency furnace in order to discard disposable medical devices such as syringes or needles.

The present invention is to solve the above problems by using a joule heat and electric arc to sterilize and dissolve the needle to remove it to prevent secondary infection and to simplify the treatment of the needle as its technical problem. do.

1 is a drive circuit diagram for a disposable medical device disposal device according to the present invention

The present invention is a disposable medical device disposal device consisting of a case, an insertion unit for inserting a variety of needles or herbal sedimentation, and a drive circuit for sterilization and / or crushing in order to discard disposable medical devices, such as various needles or oriental medicine The driving circuit includes a power supply unit 10 for supplying DC power to the driving circuit; A switching circuit 11 for converting the DC power of the power supply unit 10 into an AC power source; A charging unit 12 charged by AC power supplied from the switching circuit 11 for supplying a crushing voltage for pulverizing various needles or herbal sedimentation; An amplification unit 20 for supplying a crushing voltage after generating sterilization and thermal fatigue phenomena by generating heat to collect various needles or herbal immersion; A smoothing unit 30 for converting the AC power amplified by the amplifying unit 20 into a DC power source; And an output stage 40 for supplying power to various needles and herbal sinks on the load side.

In the present invention, it has a case which can completely block from the arc generated during various needles or herbal infiltration grinding, and an inlet through which needle and infiltration can be inserted in the upper part of the case. In order to reduce unnecessary energy loss by lowering the contact resistance of the inserted needle and the like.

In addition, the holder is connected to a voltage applying line and a ground line for supplying current to generate joule heat, and in order to facilitate movement, the power supply unit preferably uses a rechargeable battery. However, it is also possible to install a separate container for collecting the pulverized material produced at the time of a large amount of crushing, such as a hospital.

Hereinafter, a driving circuit for driving the disposable medical device disposal device in the configuration of the present invention is shown in FIG. 1.

The power supply unit 10 supplies power to the disposable medical device disposal device and uses a battery in consideration of portability and the like.

The switching circuit 11 uses a MOSFET, which is a semiconductor element, to convert the DC power of the power supply unit 10 into an AC power source, and minimizes the loss in the rear amplification unit 20 and maximizes the energy transfer. Adjust the switching time.

Since the charging unit 12 has a large amount of current required for sterilization and pulverization of various needles or cold weather at the output terminal 40, the charging unit 12 is installed to supply a current required by the output terminal 40. The output of the output unit 12 and the amplifying unit 20 is controlled and changed in order to increase the energy required according to the load change (size of the needle, etc.) at the output terminal 40.

The amplification unit 20 generates thermal fatigue phenomenon by using various kinds of needles or acupuncture for sinking, and then amplifies the voltage to supply a predetermined voltage or more for crushing. It is preferable to use a wound transformer to supply sufficient energy for the grinding.

The smoothing unit 30 is a circuit for converting the power amplified by the amplifying unit 20 into an AC power source (AC) and converting it back into a DC power source (DC).

The output stage 40 is for supplying power to various needles or herbal sinks to be discarded as loads.

The protection circuit cuts off the power supply of the input terminal when abnormal power is generated during the operation of the MOSFET for frequency oscillation in the switching circuit 11 or the current generated from the charging unit 12 flows back to the switching circuit 11 and the power supply unit 10. The protection circuit 1 (51) and amplification unit 20 or the smoothing unit 30 that operates to prevent the abnormality is generated and the protection designed to protect the device and people by blocking the power supply unit 10 for the entire circuit protection Circuit 2 (52).

According to the present invention, the use of a simple treatment device efficiently and safely handles needles that are treated as special industrial waste, thereby preventing the medical personnel and other collection workers who handle the needles from being injured by needles, causing infection or body damage. You can prevent it.
