Detailed Description

In order to make the technical solution of the present utility model better understood by those skilled in the art, the technical solution of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model, and it is apparent that the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present utility model without making any inventive effort, shall fall within the scope of the present utility model.

Example 1

As shown in fig. 1, this embodiment provides a dressing structure for a respiratory mask, including a sealing layer 1 attached to the respiratory mask, a buffer layer 2 connected to the sealing layer 1, and a dressing layer 3 located at the bottom of the buffer layer 2, wherein:

the sealing layer 1 comprises a groove matched with the edge of the breathing mask and a side wing extending upwards along the groove, and the side wing is tightly attached to the inner wall of the breathing mask;

the buffer layer 2 comprises a plurality of folding films, and a certain buffer step exists between the folding films;

the dressing layer 3 comprises a functional patch 4 attached to the skin, and functional patches 4 for physiotherapy are uniformly distributed on the surface of the functional patch 4.

Working principle: when in use, the hard breathing mask is sleeved with the dressing structure, namely the sealing layer 1 is matched with the groove of the breathing mask; then the breathing mask is matched with the head of a patient, the binding bands at the back of the head are adjusted, the buffer steps of the buffer layer 2 deform to different degrees under the control of the tightness of the binding bands, and whether the sealing layer 1 and the buffer layer 2 are worn in place is judged by observing whether the negative pressure between the breathing mask and the chest of the patient is constant or not; otherwise, the binding band behind the brain of the patient is continuously restrained. The skin of patient's face contacts with dressing layer 3, and functional paster 4 for physiotherapy carries out the physiotherapy to patient's skin on the dressing layer 3 to adsorb the sweat that patient's skin gives off through the active carbon granule, prevent that patient's sweat from breeding the bacterium and producing the pressure sore.

Example 2

On the basis of the embodiment 1, the groove is positioned at the bottom of the sealing layer 1 and the top of the buffer layer 2, and a plurality of bulges are arranged on the inner edge of the groove and are contacted with the breathing mask. The sealing layer 1 is tightly attached to the breathing mask, and the side wings are added to further reduce the problem of insufficient sealing, so that the tightness of the mask is ensured;
