Description

[0002] Sterilizer with sterilizing agent management system [

The present invention relates to a sterilizer, and more particularly, to a sterilizer management system capable of counting and identifying the remaining amount of sterilizing agent in a sterilizer provided with a bottle type sterilizing agent supply system and managing the expiration date of the sterilizing agent .

Generally, a sterilizing agent is a chemical substance which sterilizes bacteria and bacterial cell membranes by a strong oxidation reaction. When it reacts with oxygen or ultraviolet rays in the air, it loses sterilizing power. Therefore, it is circulated and operated in a closed container. When the shelf life expires, it is discarded. Accordingly, in the case of a sterilizer using a sterilizing agent, it is very important to manage the remaining amount of the sterilizing agent and the expiration date. If the sterilizer is operated beyond the validity period or when the sterilizer is depleted, sterilization will not be performed normally.

In the case of a sterilizer using hydrogen peroxide as a sterilant, one ampoule may be supplied at a time, a plurality of ampoules may be used in a cassette type, and a bottle type may be used. A sterilization agent supply system such as a system in which the sterilization agent is subdivided and a system in which the sterilization agent is subdivided by storing it in an internal storage space is used.

However, the use of one ampoule in the sterilant supply system of this type has inconvenience to be frequently changed by the user because it can not be used several times. In addition, since the ampoule must be blown out of the sterilization process and the toxic chemical substance is present after the termination, the user can not directly touch the ampoule. Therefore, there is a system for collecting the ampoule separately so that the manufacturing cost is high, There was a danger that there was a danger.

On the other hand, the bottle type sterilizer supply system has an advantage that the replacement period after mounting is longer than that of the ampule type. However, if the sterilizer is sealed once, it can not be removed until it is used, There is a disadvantage that it is inconvenient to do.

Korean Patent Laid-Open No. 10-2014-0077109 (date of publication: June 23, 2014) relates to retarding the decomposition of the cartridge into which the extraction tube is inserted, or the sterilizing agent in the tank. A sterilization apparatus for sterilizing an object by extracting the sterilant from a cartridge containing sterilant, the sterilization apparatus comprising: an extraction tube for extracting a sterilizing agent from the cartridge; The position of the extraction tube relative to the cartridge when the extraction tube is waiting for extraction of the sterilizing agent from the cartridge by the extraction tube to perform the next sterilization treatment with the same cartridge, And a moving means for moving the extraction tube so that each of the extraction tubes is different from the first extraction tube, the sterilization method, and the recording medium.

The above cited technique provides a technique for maintaining sterilizing power by providing a sterilizing agent movement path that minimizes the contact between the sterilizing agent in the container and the outside air.

However, there is a need for additional measures for the management of residual use or shelf life of the sterilant.

While the invention is susceptible to various modifications and alternative forms, specific embodiments thereof are shown by way of example in the drawings and will herein be described in detail. It is to be understood, however, that the invention is not to be limited to the specific embodiments, but is to be understood to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the invention, And the scope of the present invention is not limited to the following examples.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings, wherein like or corresponding elements are denoted by the same reference numerals, and redundant explanations thereof will be omitted.

FIG. 1 is a block diagram showing an embodiment of a sterilizer provided with the sterilizer management system of the present invention, and FIG. 2 is a perspective view showing an embodiment of a sterilizer provided with the sterilizer management system of the present invention.

1, a sterilizer 100 including a sterilizer management system according to an embodiment of the present invention includes an RF reader 110, a sterilizer supply line 120, a flow rate control unit 130, A cylinder 150, a quantity confirmation sensor 160, a control unit 180, and a container 200.

First, the sterilizing agent supply line 120 is a path through which the sterilizing agent moves from the container 200 to the sterilizing chamber 10 so that the flow adjusting unit 130, the quantifying cylinder 150 and the quantitative check sensor 160 are connected do.

The flow rate control unit 130 is installed in a sterilizing agent supply line 120 which provides a path for supplying the sterilizing agent discharged from the outlet to the sterilizing chamber 10 and regulates the flow rate of the sterilizing agent. The flow rate control unit 130 may be a flow rate control valve, for example, and may be a manual valve or a control valve operated according to a control signal. Here, the sterilization chamber 10 constitutes a part of the sterilizer, and provides an airtight space for allowing the sterilized object located inside to be sterilized by the sterilant.

The metering cylinder 150 allows the sterilant to be supplied in a predetermined amount through the sterilant supply line 120 through the quantitative confirmation sensor 160 for measuring the flow rate of the sterilant passing through the flow rate control unit 130. The quantitative confirmation sensor 160 calculates the flow rate of the sterilizing agent sensed by the sensor and transmits the flow rate to the controller 180 to control the operation of the quantifying cylinder 150 so that the sterilizing agent is supplied in a predetermined amount.

3 and 4, the sterilizer 100 according to the present invention is a device for supplying a sterilant from a replaceable hermetically sealed container 200 and supplying a predetermined amount into the sterilization chamber. As described above, the sterilizing agent such as hydrogen peroxide is oxidized by oxygen in the atmosphere and ultraviolet rays. Accordingly, the container 200 is made of a pressure-resistant material that seals and shields these factors and is resistant to the gas pressure to be injected for extruding the sterilizing agent, and can have various shapes as well as the round container as in the present embodiment.

Referring to FIG. 5, the container 200 is mounted in a container receiving chamber 190 provided at one side of the sterilizer 100. The chamber 190 is provided with a mounting portion 140 and the outlet 220 provided at the lower end of the container 200 is coupled to prepare the sterilant to be supplied into the sterilization chamber 10. [

At this time, an RFID tag 210 is provided on one side of the container 200 and an RF reader 110 is provided on one side of the chamber 190 to read or write usage data of the container 200 from the RFID tag 210 have. The RFID tag 210 may be recorded with a list of sterilizers to which the container 200 can be attached, a time when the container is mounted on the mounting portion 140 for the effective use period of the sterilizing agent, and a remaining amount of the sterilizing agent.

The list of sterilizers to which the container 200 can be mounted is an example in which if the specifications of the outlet 220 of the container 200 and the mount 140 are not compatible, When the container 200 is installed, the control unit 180 reads the information from the RFID tag through the RF reader 110 to display an alarm through the display unit 170 when the container 200 is not the proper container 200, .

Since the sterilizing power of the sterilizing agent sealed in the container 200 is effective for the effective use period of the sterilizing agent, even if the container 200 is sealed, the sterilizing power may be lowered after the lapse of the period, It is possible to check the container 200 when the container 200 is mounted.

When the container 200 is mounted on the mounting portion 140, airtightness is maintained between the container 200 and the mounting portion 140, but the sterilant starts to deteriorate due to various factors. Therefore, it is necessary to count the period during which the sterilizing power of the sterilizing agent is maintained from the time when the container 200 is mounted. Accordingly, the date and time when the container 200 is first attached to the mounting portion 140, Lt; RTI ID = 0.0 > 210 < / RTI > The control unit 180 counts down the validity period of the sterilizing agent on the basis thereof, and if the valid period has passed, the controller 180 may display an alarm or generate a warning sound through the display unit 170.

The control unit 180 may calculate the remaining amount of sterilizing agent remaining in the container 200 from the flow rate information of the sterilizing agent measured by the quantitative confirmation sensor and record the remaining amount of the sterilizing agent in the RFID tag 210 through the RF reader 110 . Accordingly, even when the container 200 is replaced and the RFID tag 210 is mounted on the other sterilizer 100, the remaining amount of the sterilizing agent can be grasped immediately from the RFID tag 210 because the remaining amount is recorded every time the sterilizer is used.

Although not shown in the drawings, the shielded container can be reused by recharging the sterilizing agent, so that the RFID can be easily attached to a side of the container 200 such as a sticker, a card, And may be provided with either a medal or a label tab. The card-shaped RFID tag may further include a card holder capable of inserting a card into one side of the container. In addition, a ring may be formed on one side of the container for attaching the connecting strap to attach the RFID tag in the form of a medal or a label tab.

The operation of the sterilizer provided with the sterilizer management system according to the present invention will now be described.

5 and 6 are flowcharts illustrating the operations of the controller of the sterilizer provided with the sterilizer management system according to the present invention.

Referring to FIG. 5, a flowchart is shown in which the controller 180 confirms the validity period of the sterilizing agent. When the container 200 is mounted on the mounting portion 140 and information of the RFID tag 210 is input from the RF reader 110, the controller 180 controls the container 200 to be mounted on a suitable model compatible with the sterilizer 100 Confirm whether it is.

Thereafter, the controller 180 checks the recording start date of the container 200 from the RFID tag 210, checks the validity period value when there is a record, and records the start date of the new container 200. The validity period value can be calculated by comparing the period in which the container 200 is preliminarily input with the current time and date on the container 200. When the validity period has elapsed as a result of the calculation, a replacement alarm is displayed or a warning sound is generated through the display unit 170.

If the validity period has not elapsed, the validity period value is repeatedly counted until the expiration date of the expiration date, and then the counted down period is counted from the present date and time.

6 is a flow chart for confirming the remaining amount of the sterilizing agent by the control unit 180. As shown in FIG. The control unit confirms the remaining amount of the sterilizing agent recorded in the RFID tag 210 of the container 200 through the RF reader 110. If the remaining amount of the sterilizing agent is not smaller than the one used amount, the sterilizer is operated and the remaining amount of the sterilizing agent is updated. That is, the amount of the first sterilization agent remaining amount is subtracted from the first sterilization amount, and the amount of use is recorded again in the RFID tag 210. When the remaining amount of the sterilizing agent in the container 200 is smaller than the used amount by one cycle, a replacement alarm may be displayed on the display unit 170 or a warning sound may be generated. The use amount of the sterilizing agent may be set in advance by the user.

Thus, even if the container 200 is replaced during the use of the sterilizing agent, the remaining amount of the sterilizing agent in the container 200 and the effective amount of the sterilizing agent in the container 200 Since the period can be easily grasped, the sterilizing power of the sterilizer can be maximized.

Although the present invention has been described with reference to the accompanying drawings, it is to be understood that various changes and modifications may be made without departing from the spirit of the invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be determined by the equivalents of the claims, as well as the following claims.
