Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an inflatable head and face protection device. Background Art

[0002] Due to the different parts of the surgical operation, the surgical position will also be different accordingly. Side lying, supine lying or prone lying are all very common. When it is necessary to lie on the side or prone lying for a long time during or after the operation, the patient's head and face must be protected. In the prior art, a head ring made of gel material is generally used to protect the head, but there are still certain limitations for some local protections, and it is impossible to effectively protect the entire head and face. The protection of the auricle, eye periorbital area, zygomatic bone, and mandibular angle in the side-lying and prone positions by the traditional head ring is still in an intervention with personal subjective feelings, so there is a great risk of pressure injury. For prone patients with intubation general anesthesia and long surgical time, it is necessary to raise the patient's head in a targeted manner during the operation and postoperative recovery period to relax the compressed area to facilitate the patient's blood flow recovery and reduce the occurrence of pressure injury. This requires the circulating nurse to manually raise the head for 3 to 5 minutes every 1 to 2 hours to reduce the pressure on the head, which is easy to strain the hand joints of the circulating nurse. In addition, when the human intervention is removed, sometimes the compressed position of the head is forgotten to be adjusted again, which is easy to cause pressure injuries to the head and face.

[0003] In Chinese patent CN201420353628.5, a prone ventilation medical care inflatable cushion is provided, including an inflatable cushion body, the inflatable cushion body includes an air cushion, the air cushion is mainly composed of 4 or 6 convex-shaped airbags which are sequentially arranged, the convex-shaped airbags are composed of upper and lower double-layer inflation chambers which are connected and a cloth cover which wraps the upper and lower double-layer inflation chambers inside, each convex-shaped airbag is sequentially connected into one body through the cloth cover, adjacent convex-shaped airbags are separated and not connected, each convex-shaped airbag is provided with an air inlet nozzle for connecting an inflation pump, the convex-shaped airbags in odd rows are connected through the air inlet nozzle, the convex-shaped airbags in even rows are connected through the air inlet nozzle, the convex-shaped airbags in odd rows and the convex-shaped airbags in even rows are alternately inflated through the air inlet nozzle to disperse the pressure of the patient's weight on the skin circulation blood flow.

[0004] However, the prone ventilation medical care inflatable cushion can only be used in the prone position, and is easily displaced during inflation and deflation, which affects the use, and the comfort level of use is not enough.

[0005] Therefore, it is necessary to provide an inflatable head and face protection device which is applicable to the prone position and the lateral position and is easy to operate and comfortable to use. Utility Model Content
