A head support device for prone position under general anesthesia

Abstract

The invention relates to a general anesthesia prone position head support device which comprises a headrest support frame and a connecting plate fitted to the headrest support frame through a connecting mechanism. A semicircular inflation headrest is fixed above the headrest support frame. The connecting plate is located in a rear-end opening direction of the semicircular headrest. The connecting mechanism comprises a turning mechanism which is mounted on the headrest support frame and allows the front end of the headrest support frame to turn downwardly relative to the connecting plate. The connecting plate is provided with a positioning mechanism for being fixed on an operation bed. The semicircular headrest fits a human face and provides flexible support, extrusion of the face is reduced, and breathing is facilitated by a hollow part of the headrest. By the turning mechanism, the headrest support frame can be turned downwardly relative to the connecting plate, and head positions can be adjusted according to needs during operations. The head support device accords to physiological bending of human cervical vertebras, is quite convenient to use, and applicable to general anesthesia prone position operations.

Description

technical field [0001] The invention relates to a medical device, in particular to a head support device for prone position under general anesthesia. Background technique [0002] During spine surgery and posterior cranial fossa craniotomy, the patient needs to lie face down on the operating bed, and at this time, the patient's head needs a support body. Clinically, a head frame or head rest is used to achieve the purpose of support. Among them, the use of a headrest is an invasive operation, which is likely to cause problems such as subcutaneous hematoma, skull injury, and infection; the headrest is much less harmful to the patient than the headrest, but most of the current headrests use granular foam as filler , it has poor elasticity and insufficient softness, and fails to take into account the difference in the face shape of the patient, which makes it easy to squeeze the skin at the frontal bone and cheekbones. cause pressure sores. [0003] In addition, most of the ...

Problems solved by technology

Among them, the use of a headrest is an invasive operation, which is likely to cause problems such as subcutaneous hematoma, skull injury, and infection; the headrest is much less harmful to the patient than the headrest, but most of the current headrests use granular foam as filler , it has poor elasticity and insufficient softness, and fails to take into account the difference in the face shape of the patient, which makes it easy to squeeze the skin at the frontal bone and cheekbones. cause pressure sores

[0003] In addition, most of the currently commonly used headrests are fixed. After the patient is prone, it does not conform to the physiological curvature of the human cervical spine, and it is difficult to adjust the surgical position for different operations and different patients, which brings considerable inconvenience to the use. much inconvenience
