Description

Technical Field

[0001] This utility model relates to the field of hospital ophthalmology treatment equipment technology, and in particular to a supportive adjustable headrest. Background Technology

[0002] In clinical practice, when treating patients' / children's eyes or cleaning and suturing lacerations, we need to immobilize the patient's head to avoid excessive movement during the procedure that could affect the outcome. However, existing head support pillows are relatively soft and cannot be adjusted in width, making them unsuitable for children. Children often require family members to assist in supporting their foreheads, which carries the risk of excessive pressure. At the same time, medical staff's hands are left unsupported, which can affect their condition during prolonged continuous treatment. Therefore, there is an urgent need for an adjustable head support pillow that can be freely adjusted in width, is suitable for patients / children, and provides support for medical staff's hands.

[0003] Therefore, there is an urgent need for a supportive, adjustable headrest to solve the above problems. Utility Model Content
