Wash water is stored in the water replenishment bottle 2, and the wash water is replenished to the wash tank 1 through a pipe by opening and closing the electromagnetic valve 3 for water supply.

In the cleaning tank 1, the US handpiece 120 and the I / A handpiece 130 are held by the holding means (not shown) so that the tip tips of the US handpiece 120 and the I / A handpiece 130 are down. Yes. The setting position of the lower limit sensor 1b is slightly above the position of each tip. When the water level of the cleaning water reaches the position of the lower limit sensor 1b, it will soon be impossible to wash (suction), so the lower limit sensor 1b detects the water level and emits an alarm sound from the alarm unit 23 (see FIG. 2). Notify the person in charge.

The upper limit sensor 1a is installed at a position where the tip tips of the US handpiece 120 and the I / A handpiece 130 are sufficiently immersed in the cleaning water, and further detects in advance that the stored cleaning water overflows, and an alarm unit A warning sound is emitted from 23 to notify the person in charge of the work.

If the upper limit sensor 1b or the lower limit sensor 1a detects the upper limit or the lower limit of the cleaning water, the solenoid valve 3 is automatically controlled so that the cleaning water is always at an appropriate water level (between the upper limit sensor 1a and the lower limit sensor 1b). It is also possible to control such that the water level is maintained.

Reference numeral 25 denotes a foot switch for setting the suction pressure for suction and the amount of air blown. The operator performs the control described later when the operator steps on the pedal of the foot switch 25 with his / her foot.

As shown in FIG. 6, the operation unit (switch panel) 22 includes a main switch 22a, an automatic mode selection switch 22b, a manual mode selection switch 22c, a foot switch / fixed / variable setting switch 22d, and a suction pressure. A selection switch 22e, an air blow selection switch 22f, and a start switch 22g are provided.

The foot switch / fixed / variable switch 22d can select and set either variable or fixed. In the “variable mode” in which “variable” is selected, the strength of the initial setting value that is set to the maximum by the angle at which the operator steps on the foot switch 25 can be controlled. In the “fixed mode” in which “fixed” is selected, The initial set value can be controlled to the maximum value simply by depressing it.

Each time the suction pressure selection switch 22e is pressed, the suction pressure can be switched and selected, and the selected value is displayed by an indicator. As for the suction pressure, the minimum value is 0 mHg and the maximum value is 500 mHg, and the suction pressure during that time can be selected in six stages. Here, the initial setting value of the suction pressure in the cleaning process is 200 mHg.

Further, each time the air blow selection switch 22f is pressed, the air flow rate can be switched and selected, and the air flow rate has three stages of MAX (maximum value), MID (intermediate value), and MIN (minimum value). Here, the initial setting value of air blow in the drying process is MID (intermediate value).

Next, the operation of the first cleaning machine SK1 (cleaning apparatus SJ) configured as described above will be described with reference to the flowchart of FIG. A series of operations is controlled by a control unit (not shown).

First, the US handpiece 120 and the I / A handpiece 130 are mounted at predetermined positions of the first cleaning machine SK1. Specifically, the first branch path 5a is detachably connected to the outlet 133a of the I / A handpiece 130 in a watertight manner, and the second branch path 5b is detachable in a watertight manner to the inlet 132a of the I / A handpiece 130. Connected. Further, the third branch path 5c is detachably connected to the outlet 123a of the US handpiece 120 in a watertight manner, and the fourth branch path 5d is detachably connected to the inlet 122a of the US handpiece 120 in a watertight manner.

When the main switch 22a is turned on (step S101), the electromagnetic valve 3 is opened and water supply from the water supply bottle 2 to the cleaning tank 1 is started (step S102).

When the water supply to the cleaning tank 1 continues and the upper limit sensor 1a detects water (YES in step S103), the solenoid valve 3 is closed and the supply of cleaning water for one set to the cleaning tank 1 is completed (step S103). S104). Here, one set of washing water is the amount of water that can wash a total of four channels of the US handpiece 120 and the I / A handpiece 130, and this amount can be terminated at the position of the upper limit sensor 1a. So that the time can be set.

Next, it is determined whether or not the automatic mode is selected based on ON / OFF of the automatic mode selection switch 22b (step S105). If the automatic mode is selected (YES in step S105), the control is shifted to step S111.

If it is not the automatic mode (NO in step S105), the manual mode is selected based on the ON / OFF state of the manual mode selection switch 22c, so that “fixed” or “variable” is selected for the foot switch / fixed / variable setting switch 22d. Based on this, it is determined whether or not the suction pressure and the air volume are fixed (step S106). If the suction pressure and the air flow rate are fixed (YES in step S106), the foot switch 25 is disabled (step S107), the suction pressure is set to an arbitrary value by the suction pressure selection switch 22e (step S108), and the air blow is selected. After the air blow amount is set to an arbitrary value by the switch 22f, the control is moved to step S112. If the suction pressure and the air flow rate are not fixed (NO in step S106), the foot switch 25 is validated (step S110), and the control is shifted to step S112. When the foot switch is validated, the operator can control the suction pressure and the air volume in accordance with the depression state of the foot pedal within a range where the suction pressure and the air volume do not exceed the initial set values.

Then, the suction pressure by the liquid pump 14 is applied to the inflow path 132 of the I / A handpiece 130 through the drain pipe 12, the main pipe 5, and the second branch path 5 b, and the washing water stored in the washing tank 1 is I / A is absorbed from the outlet 132b of the handpiece 130, passes through the inflow path 132, and enters the first drainage bottle 13a from the inlet 132a through the second branch path 5b, the main pipe path 5, the three-way solenoid valve 4 and the drain pipe 12 Led. When the water absorption operation of this route is performed for a predetermined time, cleaning of the inflow path 132 of the I / A handpiece 130 is completed.

Next, the second electromagnetic valve 6b is closed, while the fourth electromagnetic valve 6d is opened (step S114). Then, the suction pressure by the liquid pump 14 is applied to the inflow path 122 of the US handpiece 120 through the drain pipe 12, the main pipe 5, and the fourth branch path 5 d, and the cleaning water stored in the cleaning tank 1 is transferred to the US handpiece. Water is absorbed from the outlet 122 b of 120, passes through the inflow path 122, and is guided from the inlet 122 a to the first drain bottle 13 a through the fourth branch path 5 d, the main pipe path 5, the three-way solenoid valve 4 and the drain pipe line 12. When the water absorption operation of this route is performed for a predetermined time, the cleaning of the inflow path 122 of the US handpiece 120 is completed.

Water is absorbed from the tip 124 of 120, passes through the suction path 123, and is led from the outlet 123a to the first drain bottle 13a through the third branch path 5c, the main pipe path 5, the three-way solenoid valve 4 and the drain pipe line 12. When the water absorption operation of this route is performed for a predetermined time, the cleaning of the suction path 123 of the US handpiece 120 is completed.

Subsequently, the electromagnetic valve 6c is closed (step S117).

At the end of the cleaning process, the suction by the liquid pump 14 is terminated (step S118).

FIG. 4 shows the open / closed states of the first to fourth electromagnetic valves 6a to 6d in the above-described cleaning process. As is apparent from FIG. 4, when cleaning one flow path (inflow path or suction path), the other three flow paths are not cleaned because the on-off valves are closed. Therefore, it is possible to reliably perform cleaning for each flow path. In addition, the inflow path 132 of the I / A handpiece 130 is cleaned in the first stroke of step S113, the inflow path 122 of the US handpiece 120 is cleaned in the second stroke of step S114, and the first flow of step S115. The suction path 133 of the I / A handpiece 130 is cleaned in the third stroke, and the suction path 123 of the US handpiece 120 is cleaned in the fourth stroke of step S116 because the degree of contamination in each flow path is slight. It was because it was made to wash in order from the thing.

If the first drain bottle 13a becomes full during the cleaning process, the liquid pump 14 switches the suction operation so far to the discharge operation, and drains the first drain bottle 13a to the second drain. It can extrude to the drainage bottle 13b with a discharge pressure.

Next, the first electromagnetic valve 6a is closed, while the third electromagnetic valve 6c is opened (step S124). Then, the air blow by the air pump 8 and the piston air pump 9 passes through the suction passage 123 of the US handpiece 120 through the air conduit 11, the main conduit 5, and the fourth branch passage 5d, the inside of the suction passage 123 is dried, and the US hand It is blown out from the chip 124 of the piece 120. When the water absorption operation of this route is performed for a predetermined time, the cleaning of the suction path 123 of the US handpiece 120 is completed.

Subsequently, the electromagnetic valve 6c is closed (step S125).

At the end of the drying process, the air blow by the air pump 8 and the piston air pump 9 is finished (step S126).

In this way, in the drying process, continuous high-pressure blow and intermittent high-pressure blow are sent to the four flow paths (inflow path, suction path) of the US handpiece 120 and the I / A handpiece 130 for a predetermined time, The flow path is dried by blowing away the water droplets of the cleaning water remaining in the pipe.

Although the embodiment of the present invention has been described above, this is merely an example, and the present invention is not limited to this, and is based on the knowledge of those skilled in the art without departing from the scope of the claims. Various changes are possible.

For example, in the present embodiment, the case where two handpieces are cleaned and dried has been described, but it is needless to say that only one, or three or more handpieces can be cleaned and dried.

Moreover, although the case of the handpiece for ophthalmic surgery was demonstrated in this embodiment, of course, this invention is applicable if it is a flow-path built-in body which has two flow paths (pipe).

INDUSTRIAL APPLICABILITY The present invention can be used not only in the field of cleaning handpieces for ophthalmic surgery but also in a wide technical field of general industries for cleaning medical instruments such as medicine, biology and semiconductors.
