Technical Field

[0001] The utility model relates to the technical field of oxygen masks, in particular to an anti-falling oxygen mask. Background Art

[0002] Oxygen masks are the main accessories for positive pressure ventilation treatment of sleep apnea syndrome, chronic obstructive pulmonary disease, as well as non-invasive respiratory therapy used in various departments such as ICU to treat respiratory diseases and critically ill patients. Patients wear oxygen masks to deliver the gas output by the ventilator to the patient's mouth and nose.

[0003] The existing method of connecting an oxygen mask to an air supply pipe is generally to directly insert the oxygen pipe into the oxygen mask's oxygen supply pipe. Some oxygen pipes also have a hard sleeve on the top. Such an operation method is to put the hard sleeve onto the oxygen mask's oxygen supply pipe. However, no matter which method is used, the connection is easy to loosen, there is a risk of falling off, and the sealing between the oxygen mask and the air supply pipe is poor. Therefore, we propose an anti-falling oxygen mask. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Example 1

[0025] See also Figure 1-5 The utility model provides a technical solution: an anti-falling oxygen mask, comprising a mask body 1 and an air inlet pipe 11 fixed to the mask body 1, the air inlet pipe 11 is provided with a card slot 12, the card slot 12 is annular, and further comprising:

[0026] Tube 1 2, which is fixed to the mask body 1, has a plurality of holes 21 arranged in a circular array.

[0027] Clamping member 3, there are several clamping members 3, installed on the cylinder 1 2, and pass through the hole 1 21, the clamping member 3 corresponds to the position of the card slot 12;

[0028] The transmission member 4 is mounted on the mask body 1 and connected to the clamping member 3. The transmission member 4 squeezes the oxygen tube through the clamping member 3.

[0029] The wearing piece 5 is installed on the mask body 1, and the wearing piece 5 fixes the mask body 1 on the patient's face.

[0030] The clamping member 3 includes a support rod 31 that is installed through the hole 21. There are several support rods 31, and the top of each support rod 31 is provided with an inclined groove 32.

[0031] The inclined groove 32 can push the support rod 31 upwards during the insertion of the oxygen tube, ensuring that the oxygen tube can be inserted deep.

[0032] The transmission member 4 includes a second cylinder 41 mounted on the mask body 1, and a slide rail 42 is opened on the second cylinder 41. There are several slide rails 42. The outer shell of the second cylinder 41 is connected with a ring 43. The inner wall of the ring 43 is mounted with a connecting rod 44. There are several connecting rods 44, which respectively pass through the slide rails 42. The top of the connecting rod 44 is fixed with an extrusion block 45, and the top of the extrusion block 45 is an arc surface.

[0033] The wearing part 5 includes a V-shaped hole 51 opened relative to the mask body 1, a circular hole 52 is opened on the V-shaped hole 51, a rubber plate 53 is installed through the V-shaped hole 51, and a convex point 54 is provided on the rubber plate 53. There are several convex points 54, and a fixing seat 55 is installed on one end of the rubber plate 53. An elastic bandage 56 is installed on the fixing seat 55, and the two ends of the elastic bandage 56 are respectively fixed to the fixing seat 55 on one side.

[0034] The inner wall diameter of the cylinder 2 is larger than the outer wall diameter of the oxygen tube and the universal hard sleeve installed on the top of the oxygen tube.

[0035] After the oxygen tube or its hard sleeve is connected to the air inlet pipe 11 , it can be fixed by the clamping member 3 .

[0036] The present embodiment is mainly aimed at the device in which the oxygen tube is directly connected to the mask body 1. Its working principle is as follows: the oxygen tube is sleeved onto the air inlet pipe 11, and then the collar 43 is rotated. The collar 43 drives the extrusion block 45 to rotate through the connecting rod 44. During the rotation of the extrusion block 45, its arc-shaped surface presses the support rod 1 31. When the top of the extrusion block 45 contacts the support rod 1 31, the connecting rod 44 is just at the end of the slide rail 42. Since the oxygen tube itself has a certain elasticity, when the support rod 1 31 presses it downward, the oxygen tube part is squeezed into the card groove 12 on the air inlet pipe 11, and the squeezed part is "S" shaped, and the outer wall of the oxygen tube is in close contact with the top of the support rod 1 31, and friction The force is greatly increased, making it difficult for the oxygen tube to fall off. When the oxygen tube needs to be removed, it is only necessary to reversely rotate the ring 43 to release the fixation of the oxygen tube by the clamping member 3 and directly pull it out. After the oxygen tube is connected, it is worn on the patient's face, and the rubber plate 53 slides on the V-shaped hole 51 connected to the circular hole 52. At this time, the convex point 54 on the rubber plate 53 passes through the circular hole 52, and the rubber plate 53 can move normally to make the mask body 1 fit the patient's face. After moving to a suitable distance, move the rubber plate 53 to the other part of the V-shaped hole 51. At this time, the V-shaped hole 51 blocks the convex point 54, so that the rubber plate 53 cannot move, and the breathing mask is fixed to the patient's face.

[0037] Example 2

[0038] See also Figure 6 Based on Example 1, this application proposes another technical solution for the clamping member 3:

[0039] The clamping member 3 includes a second support rod 301 that is installed through the first hole 21. A rubber sheet 302 is installed on the top of the second support rod 301. The rubber sheet 302 is arc-shaped.

[0040] This embodiment mainly focuses on the device of the hard sleeve at the top of the oxygen tube and the mask body 1. The rotating ring 43 drives the extrusion block 45 to squeeze the rubber sheet 302 at the top of the second support rod 301, so that the rubber sheet 302 is tightly attached to the outer wall of the hard sleeve, limiting the position of the hard sleeve, thereby indirectly fixing the oxygen tube. The other parts are the same as those in Example 1.
