Description

Technical Field

[0001] The utility model relates to the field of medical auxiliary equipment, in particular to a face mask. Background Art

[0002] Non-Invasive Ventilation (NIV) is a technology that provides respiratory support through a mask or nasal mask, without the need for tracheal intubation or incision, and is therefore called "non-invasive". It is mainly used to treat various respiratory failures, such as acute exacerbation of chronic obstructive pulmonary disease (COPD), acute pulmonary edema caused by heart failure, and long-term treatment and assisted ventilation for patients with certain types of respiratory failure.

[0003] For patients who need to be inserted with a nasogastric tube for ventilator ventilation treatment, in order to facilitate the insertion of the nasogastric tube while wearing a mask, a hole is opened on the mask to facilitate the insertion of the nasogastric tube. However, the connection between the mask and the nasogastric tube lacks fixation and sealing, which makes the insertion of the nasogastric tube inconvenient and has poor stability, and at the same time destroys the sealing of the mask. In addition, the mask is not worn firmly or there is a gap between the mask and the patient's wear, which affects the sealing and reliability of the mask on the ventilator, and the comfort of use is poor, and the functionality and practicality are poor.

[0004] In order to solve the above problems, there are masks with nasogastric tube insertion ports, such as a simple non-invasive ventilator for patients with indwelling gastric tubes disclosed in CN115177834A and a multifunctional oxygen mask disclosed in CN104968386B. However, these masks cannot adjust the size of the opening for inserting the nasogastric tube, and are not convenient for switching the fixing of tubes with different outer diameters. Utility Model Content

[0012] Further preferably, a U-shaped gap is provided between the rotating seat and the elastic meshing tooth plate, so as to ensure the elastic movement of the elastic meshing tooth plate.

[0013] Further preferably, a shifting protrusion is arranged on the outer side of the elastic meshing tooth plate, so as to facilitate the shifting of the elastic meshing tooth plate and realize the mutual disengagement of the elastic meshing tooth plate and the toothed structure.

[0014] Further preferably, the head fixing structure comprises two upper fixing straps located above the ears and two lower fixing straps located below the ears, and ends of the upper fixing straps and the lower fixing straps are provided with through holes for passing the straps;

[0015] The head fixing structure further comprises a fixing strap structure, wherein the fixing strap structure is provided with four extending branches, each extending branch is used to pass through the through holes at the ends of the upper fixing strap and the lower fixing strap respectively;

[0016] The fixed strap structure is connected to the cover body via a connecting strap with adjustable length;

DETAILED DESCRIPTION

[0029] See also Figures 1 to 3, Specific embodiment 1, a mask with a catheter fixing port 1 with adjustable caliber, comprising a breathing mask body, the breathing mask body comprising a mask body and a head fixing structure connected to the mask body, the mask body is connected to the catheter fixing port 1, the catheter fixing port 1 comprises a rubber member 13, a fixed base 11 fixed on the mask body and a rotating seat 12 rotatably connected to the fixed base 11, the rubber member 13 is a hollow cylindrical structure with openings at both ends, one end opening of the rubber member 13 is fixedly connected to the axial inner side of the fixed base 11, and the other end opening of the rubber member 13 is fixedly connected to the axial outer side of the rotating seat 12; a one-way meshing portion that is unidirectionally meshed with the rotating seat 12 and a rotating portion that is rotatably connected to the rotating seat 12 are arranged axially on the fixed base; the one-way meshing portion is provided with a toothed structure, and an elastic meshing tooth plate 121 that is unidirectionally meshed with the toothed structure is connected to the rotating seat 12; and a movable gap for free rotation of the elastic meshing tooth plate 121 is arranged on the rotating portion. The utility model optimizes the structure of the catheter port, so that the rotating seat 12 is rotated to drive one end of the rubber member 13 to be misaligned and twisted relative to the other end, thereby realizing the change of the diameter of the hollow channel of the rubber member 13 to meet the fixation of pipelines with different outer diameters. When the pipeline needs to be loosened, the rotating seat 12 is axially moved relative to the fixed base 11, so that the fixed base 11 and the rotating seat 12 can be freely rotated relative to each other. The device fixes the pipeline through the rubber member, and can fix the pipeline in multiple directions.

[0030] The pipeline can be a nasogastric tube. The axial inner side is a side axially close to the inner side of the cover body. The axial outer side is a side axially close to the outer side of the cover body.

[0031] One-way engagement means that when the rotating seat rotates along the first circumferential direction, the elastic engagement tooth plate can move on the toothed structure along the first circumferential direction, but the elastic engagement tooth plate and the toothed structure are relatively locked in the opposite direction of the first circumferential direction.

[0032] Both ends of the rubber part in the axial direction are provided with annular protrusions. The axial inner side of the fixed base and the first pressure plate clamp one end of the fixed rubber part. The axial outer side of the rotating seat clamps the other end of the fixed rubber part through the second clamping plate. The axial outer end of the fixed base is detachably connected to a limit ring, and the outer diameter of the limit ring is larger than the inner diameter of the elastic meshing tooth plate. The limit ring is used to prevent the rotating seat from axially disengaging from the limit groove.

[0033] The fixed base is provided with a limit portion extending outwardly on the axial inner side, and a protrusion extending radially outwardly is provided on the limit portion. The outer wall of the rotating seat is provided with a positioning protrusion for aligning the protrusion. The length direction of the positioning protrusion is axial. When the protrusion is aligned with the positioning protrusion, the axial sliding of the rotating seat can axially slide and connect the elastic meshing tooth plate with the toothed structure.

[0034] The rotating seat 12 is sleeved on the periphery of the fixed base 11. A U-shaped gap is provided between the rotating seat 12 and the elastic meshing tooth plate 121. This facilitates the elastic movement of the elastic meshing tooth plate 121. A toggle protrusion is provided on the outer side of the elastic meshing tooth plate 121. This facilitates the toggle of the elastic meshing tooth plate 121 to achieve the mutual disengagement of the elastic meshing tooth plate 121 and the toothed structure.

[0035] The head fixing structure includes two upper fixing straps 3 located above the ears and two lower fixing straps 2 located below the ears. The ends of the upper fixing straps 3 and the lower fixing straps 2 are provided with through holes for passing the straps. The head fixing structure also includes a fixed strap structure 5, which is provided with four extension branches, each of which is used to pass through the through holes at the ends of the upper fixing straps 3 and the lower fixing straps 2 respectively. The fixed strap structure 5 is connected to the mask body through a length-adjustable connecting strap. The connecting strap is connected to a head fixing frame 4. It is convenient to achieve the fixing effect of the mask. The head fixing frame 4 is a U-shaped headband, and the outer side of the upper fixing strap 3 is provided with a through hole for slidingly connecting the U-shaped headband. It is convenient to improve the fixing effect of the mask. Silicone pads are fixed on the inner sides of the upper fixing straps 3 and the lower fixing straps 2. Improve the decompression effect.

[0036] The above are only preferred implementations of the present invention.
