Description

  The present invention relates to a headrest and an ophthalmic treatment chair including the headrest.

  2. Description of the Related Art Conventionally, a treatment chair or a treatment table provided with a headrest has been used when performing treatment such as ophthalmic medical treatment or surgery (for example, see Patent Documents 1 and 2). The headrest supports the head of a patient undergoing treatment, and includes a pillow made of a cushion member, a pillow holder, and the like. When the patient is placed on the treatment chair or treatment table, the patient holds the back of the head on the headrest. In this way, the patient's occipital region is stably supported by the headrest.

By the way, when performing ophthalmic medical care and surgery, if the patient's head moves even a little, the affected part may be displaced from the doctor's hand, which is often dangerous. In addition, during an ophthalmic surgery or the like, a patient is treated only by being subjected to local anesthesia. For this reason, during the treatment, the patient must witness the approach of a scalpel or the like, and often turns his face reflectively. For example, in ophthalmic surgery, there is a treatment method such as an ear-side incision in which a practitioner performs treatment from the side of a patient. When this procedure is used, patients tend to instinctively face away from the practitioner.
