Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention This invention relates to a device for displaying the height position of an irrigation bottle for perfusing an eyeball with an irrigation fluid in ophthalmic surgery.

Conventional irrigation solution is injected into the eye after removing the cloudy gel-like vitreous from the eyeball to maintain intraocular pressure.

The perfusate bottle is usually suspended on a stand. By changing the height of the irrigation fluid bottle along this stand, efforts are being made to maintain a constant intraocular pressure by adjusting the amount and pressure of irrigation fluid flowing into the eyeball according to the surgical situation.

Problems to be Solved by the Invention The bottle is moved up and down by a motor or the like. However, initially, the operator or nurse manually sets the bottle at the standard height position of the stand. The bottle is then moved by a motor to a required height from the standard height position to a position where the intraocular pressure can be kept constant. The reference height position at this time is, for example, the height of the patient's eyes.

However, this method is troublesome because the operator or nurse must memorize the reference height position in the storage device of the stand. Furthermore, since the reference height position must be changed depending on the height of the patient's eyes, changing it is also complicated.

On the other hand, there is a type in which a nurse or the like manually moves the bottle up and down along a stand according to instructions from the surgeon. In this case, set the bottle at the specified height position. However, it is troublesome to loosen the fixing means so that the bottle can be moved or to fix it at a specified height position. Furthermore, it is difficult for the operator to visually read the specified height position of the bottle from the scale notched on the stand during surgery.

OBJECTS OF THE INVENTION An object of the present invention is to provide an irrigation bottle position display device that allows an operator to easily manage the height position of a bottle even during surgery.

SUMMARY OF THE INVENTION The gist of the present invention is an irrigation bottle position display device as set forth in the claims.
