Description

  The present invention relates to an ultrasonic cleaning sterilization method and apparatus for efficiently cleaning and sterilizing an object to be processed such as a medical instrument.

  In medical institutions and inspection institutions such as hospitals, medical instruments are often used repeatedly. When reusing medical devices, thorough cleaning and sterilization are required to prevent secondary infection. An ultrasonic cleaning device is known as a device for cleaning such medical instruments, and a high-pressure steam sterilization device is known as a device for sterilization. Conventionally, an ultrasonic cleaning apparatus and a high-pressure steam sterilization apparatus have been used as separate apparatuses, but recently, an ultrasonic cleaning sterilization apparatus that combines ultrasonic cleaning and high-pressure steam sterilization has been proposed.

However, this ultrasonic cleaning sterilizer that combines ultrasonic cleaning and high-pressure steam sterilization uses a pressure-resistant container and an ultrasonic vibrator is attached to the outer surface of this pressure-resistant container. There was a problem that the vibration of the child was not easily transmitted to the inside and ultrasonic cleaning could not be performed efficiently. Therefore, an ultrasonic cleaning sterilization apparatus has been proposed in which an ultrasonic vibrator is covered with a cover in a pressure resistant container so as to improve the transmission efficiency of ultrasonic vibration transmitted to the cleaning liquid (for example, patent document). 1).

  However, when the ultrasonic vibrator is covered with the cover in the pressure vessel as described above, if the transmission efficiency of the ultrasonic vibration transmitted to the cleaning liquid is to be improved, the cover of the cover covering the ultrasonic vibrator It is necessary to reduce the plate thickness. However, if the thickness of the cover is reduced, the cover may not be able to withstand the pressure increase in the pressure vessel during sterilization with high-pressure steam and may be deformed. Also, to prevent such deformation of the cover, it is necessary to increase the thickness of the cover. If the thickness of the cover is increased, the transmission efficiency of the ultrasonic vibration transmitted to the cleaning liquid deteriorates, and the There is a problem that the meaning of arranging the ultrasonic transducer is lost. In addition, when an ultrasonic vibrator is placed in a pressure-resistant container, the durability of the ultrasonic vibrator may be affected by high temperature during sterilization with high-pressure steam, and the steam may leak into the cover. There is a problem that the ultrasonic vibrator may cause electric leakage.

FIG. 1 is a longitudinal sectional view showing a first example of the best mode for carrying out the ultrasonic cleaning and sterilizing apparatus according to the present invention.
The ultrasonic cleaning sterilization apparatus of this example includes a pressure resistant container 1 having a structure capable of withstanding an increase in pressure during high-pressure steam sterilization. This pressure vessel 1 is not different from the pressure vessel provided in the conventional sterilization apparatus. Connected to the pressure vessel 1 are a cleaning liquid supply line 2 as a cleaning liquid supply means, a drain line 3 for discharging the cleaning liquid, a steam supply line 4 as a steam supply means, a steam discharge line 5 and a vacuuming line 6 as a decompression means. These are the same as those used in the conventional ultrasonic cleaning and sterilizing apparatus, and the details thereof are omitted.

  The pressure-resistant container 1 has an opening 7, and a lid 8 that closes the opening 7 is provided with a vibrating lid 8 that is used during ultrasonic cleaning and a pressure-resistant lid 9 that is used during sterilization with high-pressure steam. . In this example, the opening 7 also serves as a workpiece outlet / outlet for taking in and out the workpiece.

  A plurality of ultrasonic transducers 10 are attached to the outer surface of the vibrating lid 8. The vibration lid 8 and the pressure-resistant lid 9 are supported by the pressure-resistant vessel 1 so that when one of them closes the opening 7 of the pressure-resistant vessel 1, the other retreats from the opening 7 of the pressure-resistant vessel 1.

  In this example, the vibration lid 8 and the pressure-resistant lid 9 are attached to the opening 7 of the pressure-resistant container 1 so as to be slidable in the vertical direction, and are slid to perform an opening / closing operation. The opening 7 of the pressure vessel 1 is provided with a slide guide groove (not shown) that allows the vibrating lid 8 and the pressure lid 9 to slide.

The ultrasonic cleaning sterilization method according to the present invention is carried out as follows using the ultrasonic cleaning sterilization apparatus according to the present invention.
First, the opening 7 of the pressure-resistant container 1 is closed using the vibration lid 8 to which the ultrasonic vibrator 10 is attached, and the cleaning liquid is supplied into the pressure-resistant container 1 from the cleaning liquid supply line 2 as the cleaning liquid supply means. The child 10 is operated to clean the object to be processed, the cleaning liquid is discharged from the drain line 3, and the ultrasonic cleaning is finished.

  Next, the opening 7 of the pressure-resistant container 1 is closed using the pressure-resistant lid 9, and high-pressure steam is supplied into the pressure-resistant container 1 from the steam supply line 4 serving as a steam supply means and heated to sterilize the object to be processed. Thereafter, the inside of the pressure-resistant container 1 is decompressed and dried by the evacuation line 6 serving as decompression means, and the sterilization is finished. When sterilization with high-pressure steam is completed, the opening 7 is opened, and the object to be treated after sterilization is taken out from the pressure-resistant container 1.

  In exchanging the vibrating lid 8 and the pressure-resistant lid 9, the vibrating lid 8 is slid to close the opening 7, and after the ultrasonic cleaning is finished, the vibrating lid 8 is slid and retracted from the opening 7. 9 is slid to close the opening 7, and after the sterilization with high-pressure steam is finished, the pressure-resistant lid 9 is slid to open the opening 7.

  In the ultrasonic cleaning sterilization method as described above and the ultrasonic cleaning sterilization apparatus that performs this method, the pressure-resistant container 1 serves as a lid that closes the opening 7 thereof, and a vibrating lid 8 used during ultrasonic cleaning, and sterilization with high-pressure steam. A pressure-resistant lid 9 that is sometimes used is also provided. The opening 7 of the pressure-resistant container 1 is closed using a vibration lid 8 to which an ultrasonic transducer 10 is attached, and then ultrasonic cleaning is performed. Since the opening 7 of the container 1 is closed and sterilization is performed with high-pressure steam, ultrasonic cleaning and high-pressure steam sterilization can be performed efficiently.

  That is, since the inside of the pressure vessel 1 does not become high pressure, the vibration lid 8 does not need to be pressure resistant, and therefore the vibration lid 8 can be formed thin, and the ultrasonic vibrator 10 can be formed outside the vibration lid 8. The ultrasonic vibrator 10 can be efficiently transmitted to the cleaning liquid in the pressure resistant container 1 and the ultrasonic vibrator 10 can be attached to the outside of the vibration lid 8. Since it is not affected by the high temperature during sterilization with high-pressure steam, durability can be maintained, and there is no possibility of causing electric leakage to the ultrasonic vibrator 10 due to the steam. Further, when sterilizing with high-pressure steam, the pressure-resistant lid 9 is used instead of the vibrating lid 8 and the pressure-resistant container 9 is used to close the opening 7 of the pressure-resistant container 1 and sterilization is performed with high-pressure steam. Steam sterilization can be performed.

  Further, in the ultrasonic cleaning and sterilization apparatus of this example, when one of the vibration lid 8 and the pressure-resistant lid 9 closes the opening 7 of the pressure-resistant vessel 1, the other retreats from the opening 7 of the pressure-resistant vessel 1. Therefore, when the opening 7 of the pressure-resistant vessel 1 is opened and closed, one lid does not interfere with the other lid and can be easily opened and closed. In particular, in this example, the vibrating lid 8 and the pressure-resistant lid 9 are slidably attached to the opening 7 of the pressure-resistant container 1 and are slid to perform opening and closing operations. It is sufficient to secure an area where the vibrating lid 8 and the pressure-resistant lid 9 can slide when opening and closing each lid, and a large area for moving the vibrating lid 8 and the pressure-resistant lid 9. Do not need.

  Further, in this example, the vibrating lid 8 and the pressure-resistant lid 9 are configured separately and are arranged so that the moving directions thereof are on the same line, but as shown in FIG. The pressure-resistant lid 9 is integrally formed by being connected at one end thereof, and the integrally formed vibrating lid 8 and the pressure-resistant lid 9 are slidably attached to the opening 7 of the pressure-resistant container 1. The opening 7 of the pressure-resistant container 1 may be closed by sliding either the vibrating lid 8 or the pressure-resistant lid 9. In this way, since the vibration lid 8 and the pressure-resistant lid 9 slide together, the operation of the vibration lid 8 and the pressure-resistant lid 9 becomes easy.

  Further, as shown in FIG. 3, the vibrating lid 8 and the pressure-resistant lid 9 configured separately are arranged in parallel to the moving direction, the vibrating lid 8 moves in the arrow A direction, and the pressure-resistant lid 9 is moved to the arrow. The opening 7 of the pressure vessel 1 may be closed by moving in the B direction. In this way, the dead space is halved compared to the configuration of the vibrating lid 8 and the pressure-resistant lid 9 shown in FIGS. 1 and 2, and the space can be reduced.

FIG. 4 is a transverse sectional view showing a second example of the best mode for carrying out the ultrasonic cleaning and sterilizing apparatus according to the present invention.
In the ultrasonic cleaning and sterilization apparatus of this example, the vibrating lid 8 and the pressure-resistant lid 9 are attached to the opening 7 of the pressure-resistant container 1 so as to be able to turn left and right via a hinge. It opens and closes. By attaching in this way, the vibrating lid 8 and the pressure-resistant lid 9 can be easily opened and closed, and when the vibrating lid 8 and the pressure-resistant lid 9 are opened and closed, the vibrating lid 8 and the pressure-resistant lid 9 can be rotated. It is only necessary to secure an area, and a large area is not required to move the vibration lid 8 and the pressure-resistant lid 9. Since the other configuration is the same as that of the first example, the description of the first example is cited and the description is omitted.

  In this example, the vibrating lid 8 and the pressure-resistant lid 9 are attached to the opening 7 of the pressure-resistant container 1 so as to be rotatable in the left-right direction, but may be attached so as to be rotatable in the vertical direction. Good.

  5 to 7 show a third example of the best mode for carrying out the ultrasonic cleaning and sterilizing apparatus according to the present invention. FIG. 5 shows a state in which the opening of the pressure vessel is closed with a vibrating lid. FIG. 6 is a longitudinal sectional view showing a state in which the opening of the pressure vessel is closed with a pressure-resistant lid, and FIG. 7 is an object to be processed separately provided in the pressure-resistant vessel by closing the opening of the pressure-resistant vessel with a pressure-resistant lid. It is the longitudinal cross-sectional view which showed the state which opened the opening part for operation. Note that portions corresponding to those in FIG. 1 are denoted by the same reference numerals.

  Even in the ultrasonic cleaning sterilization apparatus of this example, as in the first example, the pressure-resistant container 1 having a structure capable of withstanding an increase in pressure during high-pressure steam sterilization is provided. A cleaning liquid supply line 2 as a cleaning liquid supply means, a drain line 3 for discharging the cleaning liquid, a steam supply line 4 as a steam supply means, a steam discharge line 5, and a vacuuming line 6 as a decompression means are connected.

  The pressure-resistant container 1 has an opening 7, and a lid 8 that closes the opening 7 is provided with a vibrating lid 8 that is used during ultrasonic cleaning and a pressure-resistant lid 9 that is used during sterilization with high-pressure steam. . Such a configuration is the same as the first and second examples except for the opening 7.

  In other words, in this example, the pressure vessel 1 is provided with an opening 11 for the object to be taken in and out, in addition to the opening 7 closed by the vibration lid 8 or the pressure lid 9. In addition, an opening / closing pressure-resistant lid 12 is attached to the workpiece opening 11 so as to be opened and closed.

  In the vibration lid 8 and the pressure-resistant lid 9, in this example, the vibration lid 8 and the pressure-resistant lid 9 are integrally formed by connecting one end thereof at the connecting portion 13. The vibrating lid 8 and the pressure-resistant lid 9 are slidably attached to the opening 7 of the pressure-resistant container 1. When the opening 7 is closed with either the vibrating lid 8 or the pressure-resistant lid 9, the other lid is operated. Without retreating from the opening 7. The opening 7 of the pressure vessel 1 is provided with a slide guide groove (not shown) that allows the vibrating lid 8 and the pressure lid 9 to slide.

  In the ultrasonic cleaning sterilization according to this example, first, the opening 7 of the pressure-resistant container 1 is closed using the vibration lid 8 to which the ultrasonic transducer 10 is attached, and the opening 11 for the object to be processed is opened with the pressure-resistant lid 12 for opening and closing. Close (FIG. 5) and perform ultrasonic cleaning as in the first example. Next, the vibrating lid 8 and the pressure-resistant lid 9 are slid to close the opening 7 of the pressure-resistant container 1 with the pressure-resistant lid 9 instead of the vibrating lid 8 (FIG. 6), and sterilization with high-pressure steam is performed as in the first example. . When the sterilization with high-pressure steam is completed, the opening / closing opening 11 for the object to be processed is opened by operating the open / close pressure-resistant lid 12 (FIG. 7), and the object to be sterilized is removed from the pressure-resistant container 1.

  As described above, in this example, the opening 7 of the pressure vessel 1 is closed using the vibrating lid 8 to which the ultrasonic transducer 10 is attached, and then the ultrasonic cleaning is performed. Since the part 7 is closed and sterilization is performed with high-pressure steam, ultrasonic cleaning and high-pressure steam sterilization can be performed efficiently as in the first example.

  Further, in this example, the vibrating lid 8 and the pressure-resistant lid 9 are integrally formed by being connected at one end thereof, and the integrally formed vibrating lid 8 and the pressure-resistant lid 9 are the pressure-resistant container 1. When the opening 7 is closed with one of the vibrating lid 8 and the pressure-resistant lid 9, the other lid is retracted from the opening 7 without any operation. Therefore, the operation of the vibration lid 8 and the pressure-resistant lid 9 is facilitated.

  Further, in this example, the pressure-resistant container 1 is provided with an opening 11 for the object to be processed, in addition to the opening 7 closed by the vibration lid 8 or the pressure-resistant lid 9. Since the opening / closing pressure-resistant lid 12 is attached to the object opening 11 so as to be opened and closed, the shape of the object opening 11 and the opening / closing attached to the object opening 11 are open. The attachment structure of the pressure-resistant lid 12 only needs to consider taking in and out the object to be processed, and the shape of the opening 11 for the object to be processed and the attachment structure of the opening / closing pressure-resistant lid 12 attached to the opening 11 for the object to be processed are simple. Thus, the opening / closing pressure-resistant lid 12 can be easily opened and closed and the workpiece can be taken in and out.

  In this example, the vibration lid 8 and the pressure-resistant lid 9 are attached to the opening 7 of the pressure-resistant container 1 so as to be slidable in the vertical direction, but may be attached to be slidable in the left-right direction.

  Further, in this example, the vibrating lid 8 and the pressure-resistant lid 9 are integrally formed by being connected at one end thereof, and the integrally formed vibrating lid 8 and the pressure-resistant lid 9 are connected to the pressure-resistant container 1. When the opening 7 is slidably attached to the opening 7 and the opening 7 is closed with one of the vibration lid 8 and the pressure-resistant lid 9, the other lid is retracted from the opening 7 without any operation. However, it is not limited to this.

  For example, as shown in FIG. 8, the vibrating lid 8 and the pressure-resistant lid 9 may be configured separately and may be arranged so that the movement directions thereof are on the same line. In this way, the vibrating lid 8 And the pressure-resistant lid 9 can be retracted from the opening 7 to open the opening 7, and the workpiece can be taken in and out from the opening 7 as necessary.
