Description

Technical Field

[0001] This invention belongs to the field of medical device technology and relates to a mask support frame suitable for mouth breathing after nasal surgery. Background Technology

[0002] After nasal surgery, patients' nasal cavities are packed with gauze or hemostatic cotton, causing them to breathe through their mouths. In addition, since most surgeries are performed under general anesthesia, patients need to breathe through an oxygen tube in their mouths within six hours to ensure stable vital signs. All of these factors can easily lead to accelerated evaporation of moisture in the oropharynx. In this case, patients often use wet gauze to cover their mouths to reduce oral dryness. However, this is not conducive to patient movement, and wet gauze is in direct contact with the skin, resulting in low patient comfort. Most patients are unwilling to adopt this method. Summary of the Invention

[0003] The purpose of this invention is to provide a mask support frame suitable for mouth breathing after nasal surgery. By using the mask support frame to effectively fix the nasal cannula on the outside of the mask, it facilitates patient movement and increases comfort.

[0004] The objective of this invention can be achieved through the following technical solutions: A mask support frame suitable for mouth breathing after nasal surgery includes a mask frame, connecting ears on both sides of the mask frame, ear loops through the connecting ears on both sides, longitudinal and transverse support beams that are intersected across the mask frame, and a nasal cannula assembly hole through the intersection of the longitudinal and transverse support beams. The cover frame has a through hole for the mouth and nose, and the nasal cannula assembly hole points to the through hole for the mouth and nose.

[0005] In this invention, the mask frame serves as the main structure of the mask support frame. During use, it abuts against the inside of the mask. The ear loops of the mask pass through the ear loop slots and are hung on the patient's ears, so that the mask frame and connecting ears fit snugly against the patient's face and are covered by the mask. Longitudinal and transverse support beams are installed outside the mask for attaching a nasal cannula through the nasal cannula assembly hole, ensuring the nasal cannula points towards the patient's mouth and nose for convenient use during oxygen inhalation.

[0006] Furthermore, two nasal cannula assembly holes are arranged side by side.

[0007] Furthermore, the mask frame is provided with multiple through holes as decompression holes for patient exhalation, so that the air pressure in the space between the mask support frame and the patient's face remains stable with atmospheric pressure, ensuring the patient's breathing comfort, reducing the weight of the mask support frame, and facilitating transportation, storage, and use.

[0008] Furthermore, a humidifying gauze or absorbent cotton block is attached to the outside of the cover frame, and the humidifying gauze covers the mouth and nose openings and multiple openings.

[0009] This invention increases the humidity of the air inhaled by the patient by placing a humidifying gauze or absorbent cotton pad between the inside of the mask and the support, thus ensuring the patient's breathing comfort.

[0010] Furthermore, the two ends of the longitudinal support beam are connected to the upper and lower sides of the cover frame, and the two ends of the transverse support beam are connected to the outer edges of the two sides connecting the ears.

[0011] Furthermore, both the longitudinal support beam and the transverse support beam are curved beams.

[0012] Furthermore, the ear loop groove is an arc-shaped groove with an outward opening, so that when the mask ear loops open outward, they can slide down on their own and be fixed at both ends, improving the assembly stability of the mask and mask support frame on the patient's face.

[0013] Furthermore, the two ends of the ear loop groove are provided with limiting holes, and the width of the limiting holes is greater than the width of the arc-shaped groove.

[0014] Furthermore, the mask support frame is a rubber elastic mask support frame or a silicone elastic mask support frame.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1) This invention uses a mask frame as the main structure of the mask support frame. During use, it abuts against the inside of the mask. The ear loops of the mask pass through the ear loop slots and are hung on the patient's ears, so that the mask frame and connecting ears fit snugly against the patient's face and are covered by the mask. Longitudinal and transverse support beams are installed outside the mask for attaching a nasal cannula through the nasal cannula assembly hole, ensuring the nasal cannula points towards the patient's mouth and nose for convenient use when the patient is inhaling oxygen.

[0016] 2) The mask support frame of the present invention can sandwich gauze in the middle layer of the frame and place wet gauze inside the mask, while fixing the wet gauze so that the wet gauze does not directly contact the skin, and avoids the wet gauze or absorbent cotton sticking to the face and lips, causing discomfort. 3) This invention is made of rubber or silicone material, is washable, rebounds in 1 second and is not easily deformed, and will not stick to the skin of the face.
