  As described above, the drain tray 10 receives water discharged from the instrument by the instrument leveling operation and the spray cleaning operation. After the leveling operation and the spray cleaning operation are finished, The assistant removes the drainage tray from the instrument holder and carries it to the sink in order to discard the drainage that remains in it, in which case the drainage that remains in it may be spilled, It was inconvenient.

  The present invention has been made in view of the circumstances as described above, and prevents water from remaining in the drainage tray when performing an instrument break-in operation or spray cleaning operation. The purpose is to facilitate the handling of the drain tray.

  The invention of claim 1 includes a horizontal instrument holder for mounting a plurality of dental treatment instruments including a saliva discharge tube or a vacuum tube in parallel, and the instrument mounted in parallel. A drainage tray that is detachably attached to the tip and receives the wash water discharged from the instrument, and the instrument holder has a tray detection sensor that detects that the drainage tray is attached, Only when the drainage tray is installed and the saliva discharge or vacuum tube is taken up from the instrument holder and suction is started, the instrument can be conditioned and spray cleaned. It is characterized by that.

  According to a second aspect of the present invention, in the first aspect of the present invention, an upper portion of the drainage tray has an opening for inserting the drainage or vacuum tube, and the drainage or vacuum tube is in the opening. It is characterized by enabling instrument leveling and spray cleaning when inserted.

  According to a third aspect of the present invention, in the first or second aspect of the invention, the instrument holder is freely accessible, and when the drain tray is removed, the instrument holder automatically comes to the front. It is characterized by that.

  According to the present invention, since water does not remain in the drain tray after the running-in operation or the spray cleaning operation, it is very easy to carry the drain tray.

  FIG. 1 is a schematic perspective view for explaining an embodiment of a dental instrument holder according to the present invention. In FIG. 1 (A), 1 is a work table, 2 is a work table at the bottom of the work table 1, and FIG. An instrument holder provided integrally with the table 1, and, as is well known, the instrument holder 2 has a salivary duct (some cases may not have a saliva duct) or a vacuum pipe. A large number of instruments 3 including are mounted in parallel in a horizontal manner. A drain tray 10 is detachably attached to the work table 1 or the instrument holder 2. In the illustrated example, both the concave (groove) portions 11 provided on both outer sides of the drain tray 10 and the work table 1 are provided. A convex (protrusion) portion 12 provided on the inner side is engageable, and the concave portion 11 provided on the drain tray 10 by pushing the drain tray 10 in the direction of arrow A is provided on the work table 1. The drainage tray 10 can be attached to the work table (instrument holder) 1 by being engaged with 12, and can be detached from the work table (instrument holder) by being pulled out in the reverse direction.

  The work table 1 (or the instrument holder 2) is provided with a sensor 13 (which may be anything such as an optical sensor, a magnetic sensor, or a micro switch) that detects that the drain tray 10 is mounted. In addition, as long as the valve does not operate, a break-in operation or a spray operation cannot be performed unless the saliva discharge tube or the vacuum tube is taken up from the instrument holder 2 and suction is started. The instrument holder 2 is usually provided with a sensor that detects whether or not the instrument has been picked up for each instrument, and controls the picked-up instrument (for example, for the instrument). The formation of an air supply circuit, a water supply circuit, an electric circuit, etc.) is started, and the instrument is driven.

  Therefore, prior to the start of the running-in operation or spray cleaning operation, the drainage tray 10 is attached to the instrument holder 2, and the saliva or vacuum tube is taken up from the instrument holder 2 and sucked. After confirming that the operation has started, and after these conditions are met, running-in and spray cleaning operations will not cause any drainage to remain in the drain tray. Handling of the drain tray after the washing operation becomes very easy.

Furthermore, as shown in FIG. 1 (B), the upper part of the drainage tray 10, may be provided an opening 10a for inserting the Haitsubakan or vacuum tube, discharge spit tube or tip of the vacuum tube 3 ₁ through the opening 10a When the (intake port) is placed in the drainage tray 10, the saliva discharge tube or the vacuum tube can be stably held in the drainage tray 10, and drainage can be performed reliably. At that time, a sensor is provided on the instrument holder 2 side to detect that the saliva discharge tube or vacuum tube is inserted into the opening of the instrument holder, and this sensor detects the saliva discharge tube or the vacuum tube. as also condition that other instruments, for example, air turbine, enabling the running-or spray cleaning operation instrument 3 ₂ such as a micro engine, more reliably, the running-in or spray cleaning operation It can be carried out.

  FIG. 1 shows an example in which the operation switch 14 for running-in operation and the operation switch 15 for spraying are provided on the front surface of the work table 1, but these operation switches are operated by an assistant. Any place that is easy to do.

  A display panel 16 is provided on the work table 1 (or the instrument holder 2). When the operation switch 14 or 15 is operated in a state where the above conditions are not satisfied, the display panel 16 includes, for example, , “Please attach drain tray”, “Please attach saliva tube or vacuum tube”, “Please drive saliva tube or vacuum tube”, etc. are displayed to alert the assistant. At the same time, regardless of the display panel, the same attention is urged by voice, so that it is possible to sufficiently cope with an inexperienced assistant.

  Furthermore, when performing dental treatment, the surgeon performs various operations in front of the work table. At this time, if the instrument is projected to the front, the surgeon's hand is attached to the tip of the instrument. There is a risk of injury by touching the blade. Prior to receiving treatment, the patient sits in a treatment chair, and at that time, these instruments may be in the eyes and feel frightened. In consideration of this, the instrument holder 2 is always drawn toward the back of the work table 1 so that the operator's hand can be touched as much as possible and the patient's eyes should not be touched. However, when not in use, if the drainage tray is mounted in front of the instrument and removed during treatment, the surgeon may be injured or the patient may feel uneasy as described above. There is no.

  In FIG. 1, a switch 17 is for inserting and removing the instrument holder. When the instrument holder 2 is retracted toward the back of the work table 1, pressing the switch 17 causes the instrument holder to be released. The instrument holder 2 is automatically (electrically or hydraulically) removed when the drainage tray 10 is removed. If it comes out to the air type etc., it will be easy to use.
