Description

A kind of external application mask after nose surgery

technical field

The invention belongs to the technical field of medical equipment, and specifically discloses a mask for external application after nasal surgery.

Background technique

The nasopharynx is the only way for the human body to breathe and swallow. Because of the special surgical site of nasal surgery, postoperative pain and discomfort caused by mouth breathing after nasal packing will seriously affect the patient's breathing and sleep. And diet, lead to emotional tension and depression in patients, and affect postoperative recovery. The existing method is usually to apply ice to the nose and forehead within 48 hours after the operation, which can effectively reduce the pain of the patient.

The prior art approach is to place the ice pack directly on the patient's nose. For example, Chinese Utility Model Patent (Publication No.: CN209377858U) discloses a special ice pack for nasal surgery with a fixed belt, including an ice pack protection layer and an elastic band, the elastic band is fixedly connected to one side outer surface of the ice pack protection layer, and the ice pack protection layer The outer surface of the velcro is provided with a hollow round hole and an elastic band fixing hole, the end of the elastic band away from the ice pack protective layer is fixedly connected with a Velcro, and the outer surface of the Velcro is provided with a loop fabric and a hook fabric, and the hook fabric is located at the end of the loop fabric. On one side, the number of hollowed-out circular holes is two groups, and the hollowed-out circular holes are evenly distributed in the eye parts on both sides of the center line of the ice pack protective layer.

Although the above solution can have the effect of ice compressing on the nose, because multiple long-term ice compresses are required after rhinoplasty, the ice pack will melt during the ice compress process, because the patient is under ice compress for a long time. In this state, the skin perception ability of the nose will decline to a certain extent, so that when the ice pack melts, the patient cannot find out that the inside of the ice pack has melted in time. If the ice pack is used for a long time in this state, it will not only waste a lot of time, but also the ice pack will not be able to achieve a good ice pack effect if it melts and loses its cooling ability.

SUMMARY OF THE INVENTION

The purpose of the present invention is to provide a mask for external application after nasal surgery, so as to solve the problem that the patient cannot find out the melting in the ice application process in time.
