In step ST4, the operator holds the handle 601 of the open / close door 600 shown in FIG. 2 and lifts it in the Z1 direction, thereby opening the openings 400 and 500. Thereby, the work space 210 of the work table 200 and the inside of the main body 2 of the disinfection apparatus 1 are connected via the openings 400 and 500.

  Then, the operator puts the disinfected hand in the work space 210 of the work table 200, puts the hand into the opening 400, 500 from the work space 210, and puts it in the main body 2 of the disinfection apparatus 1. The sterilized instruments that have been sterilized are carried into the work space 210 of the work table 200 from the main body 2 of the sterilizer 1 through the openings 400 and 500.

  Then, in step ST5 of FIG. 5, the worker starts work such as experiments and tests on the work table 200 using disinfected instruments. As described above, once the operator disinfects the range from the finger to the arm, the operator puts his / her hand into the work space 210 of the work table 200 and from the inside of the main body 2 of the disinfection apparatus 1 through the openings 400 and 500. Disinfected instruments in the main body 2 of the sterilizer 1 can be directly carried into the work space 210 without passing through the outside of the work table 200 or the main body 2 of the sterilizer 1.

  For this reason, once the operator disinfects the range from the fingers to the arms, the disinfected instruments in the main body 2 of the disinfecting apparatus 1 can be easily moved into the work space 210 of the work table 200. You can move on to the work you need. The operator can efficiently perform experiments and work after the disinfection work of fingers and instruments, and can improve the usability of the work apparatus 1000. For this reason, it is easy to use the disinfection device 1 and the workability of carrying instruments to the work table 200 thereafter is good.

  By the way, the control part 100 of FIG. 4 receives the water level signal from the tank water level sensors SL1 to SL3, so that the storage level of the medicine M in the medicine tank 33, the storage level of the water W in the water tank 30, The storage level of the disinfectant F in the buffer tank 40 is constantly monitored.

  For this reason, if the storage level of the medicine M in the medicine tank 33 is lower than a predetermined level, the alarm unit 250 can issue an alarm for an additional request for the medicine M. If the storage level of the water W in the water tank 30 falls below a predetermined level, the alarm unit 250 can issue an alarm for an additional request for the water W. If the storage level of the disinfectant F in the buffer tank 40 is lower than a predetermined level, the alarm unit 250 issues an alarm for requesting the additional preparation of the disinfectant F. The control unit 100 operates the first liquid feeding unit R1 of FIG. 4 to send the medicine M in the medicine tank 33 and the pure water PW produced from the water W in the water tank 30 into the buffer tank 40. Thus, for example, a 70% alcohol aqueous solution F can be stored in the buffer tank 40.

  As described above, when the disinfecting apparatus 1 according to the embodiment of the present invention is used, the disinfectant F is prepared inside the disinfecting apparatus 1 and stored in the buffer tank 40. Each time, the operator prepares a disinfectant, puts the disinfectant into a spray container (spray container), and manually disinfects the range from fingers to arms and instruments. There is no need to perform troublesome work such as spraying and disinfecting. That is, conventionally, an operator prepares pure water, dilutes and mixes the pure water and the disinfectant stock solution to prepare a disinfectant, and then puts the disinfectant into the spray container. . Then, the operator needs to prepare the prepared disinfectant and disinfect the range from fingers to arms and instruments by manually spraying the disinfectant from the spray container. Moreover, since the sprayed disinfectant scatters in the vicinity, the floor surface becomes dirty with the disinfectant.

  Conventionally, a spray container containing a disinfectant is prepared, and when an operator manually sprays the disinfectant in the spray container on the range from fingers to arms and instruments, the vicinity of the work table Disinfecting work is done by placing instruments that need to be disinfected on a cabinet placed in the area. If this cabinet is not placed in the vicinity of the work table, the work flow line becomes longer because the device must be taken to the work table every time the device is disinfected.

  Conventionally, not only spraying the disinfectant from the spray container, but also preparing a liquid disinfectant for absorbent cotton when the disinfectant is soaked in absorbent cotton to disinfect the instrument in order to use the disinfectant in liquid form. Is annoying. When multiple workers use the disinfectant in the spray container, the stock solution of the disinfectant may be insufficient.

  By using the disinfection apparatus 1 according to the embodiment of the present invention, the following effects can be obtained. The main body 2 of the disinfecting apparatus 1 is provided with a plurality of injection nozzles, in the illustrated example, an upper injection nozzle 21, a lower injection nozzle 22, and injection nozzles 171, 172, 173, 174, and 175. In addition, as shown in FIG. 3, there is a space SP1 between the upper spray nozzle 21 and the lower spray nozzle 22 that can be inserted and disinfected even in the range of fingers to arms and relatively large instruments. Between the spray nozzles 171, 172, 173, 174, and 175, there is a space SP2 that can be inserted and disinfected even in the range of fingers to arms and relatively large instruments. For this reason, since the operator can insert the range of fingers to arms or relatively large instruments into the spaces SP1 and SP2 and automatically spray the disinfectant F, the range of fingers to arms or relatively Large instruments can be sterilized reliably.

  Further, as shown in FIG. 4, the disinfectant F used for disinfection can be received by the disinfectant receiving portions 25 and 180 and recovered in the recovery tank 47. Thereby, it is possible to prevent the used disinfectant F from being scattered around and soiling the floor surface.
