Description

Technical Field

[0001] The utility model relates to the technical field of medical care appliances, in particular to a breathing mask. Background Art

[0002] With the development and progress of society and the improvement of people's living standards, the demand for caregivers is increasing and the requirements are getting higher and higher. More and more workers are entering the nursing industry. In hospitals, communities or homes, many patients receive services provided by caregivers.

[0003] During use, the existing breathing mask needs to connect the oxygen tube to the air inlet so that the patient can continuously absorb oxygen. The oxygen tube is generally plugged into the air inlet. Therefore, the oxygen tube is easily detached from the air inlet after being continuously pulled, resulting in oxygen leakage. For this reason, we propose a breathing mask. Utility Model Content

[0009] As a preferred technical solution of the present invention, a handle is welded to the outer end surface of the nut, and grooves are provided on the front and rear end surfaces of the handle.

[0010] As a preferred technical solution of the present invention, the depth of the limiting groove is half of the length of the nut, and a soft pad is glued on the surface of the nut facing the limiting groove.

[0011] As a preferred technical solution of the present invention, the threaded area on the surface of the threaded rod is only half of the length of the threaded rod.

[0021] In order to make the technical means, creative features, purpose and efficacy of the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation manner, other embodiments obtained by those skilled in the art without making creative work are all within the scope of protection of the present invention. The experimental methods in the following embodiments are all conventional methods unless otherwise specified, and the materials, reagents, etc. used in the following embodiments are all commercially available unless otherwise specified.

[0022] Example:

[0023] See also Figure 1 - Figure 5 A breathing mask comprises a mask 1, an air inlet 2 and an oxygen tube 3. The front end of the mask 1 is provided with an air inlet 2, and the air inlet 2 is provided with an oxygen tube 3. Mounting seats 41 are symmetrically provided on the surfaces of both sides of the air inlet 2. A rotating rod 42 is rotatably provided in the mounting seat 41, and multiple groups of torsion springs 43 are wound around the rotating rod 42. A threaded rod 44 is provided on the bottom end surface of the rotating rod 42, and a limiting block 45 is provided on the surface of the oxygen tube 3 below the threaded rod 44. The limiting block 45 is rotatably connected to the threaded rod 44, and a nut 46 is threadedly connected to the threaded rod 44. A handle 47 is provided on the bottom end surface of the nut 46, and a limiting groove 48 is provided on the outer wall of the limiting block 45 corresponding to the inner end of the nut 46.

[0024] When in use, first rotate the threaded rod 44 so that the threaded rod 44 drives the rotating rod 42 to rotate in the mounting seat 41. At the same time, the rotating rod 42 will continuously drive the torsion spring 43 to twist during the rotation in the mounting seat 41. Then, insert the oxygen tube 3 into the air inlet 2, and align the limit block 45 with the threaded rod 44. At the same time, loosen the threaded rod 44, and use the restoring force generated by the twisting of the torsion spring 43 to drive the rotating rod 42 to reset and rotate in the mounting seat 41. At the same time, the rotating rod 42 drives the threaded rod 44 to rotate into the limit block 45. , and abuts against the inner wall of the limit block 45. At this time, the handle 47 is turned again, so that the handle 47 drives the nut 46 to rotate on the threaded rod 44, and the nut 46 is rotated into the limit groove 48, thereby achieving the purpose of reinforcing the connection between the air inlet 2 and the oxygen tube 3. Through this device, the connection between the air inlet 2 and the oxygen tube 3 can be reinforced, and the stability of the oxygen tube 3 during use can be improved, thereby effectively preventing the oxygen tube 3 from falling off from the air inlet 2 after repeated pulling, thereby causing oxygen leakage.

[0025] In other embodiments, a sealing ring 49 is provided on the surface of the oxygen tube 3, and the area of the sealing ring 49 is larger than the area of the air inlet 2;

[0026] With this design, by rotating the nut 46, the nut 46 continuously squeezes the limiting groove 48, and then the limiting groove 48 drives the sealing ring 49 and the air inlet 2 to be continuously squeezed, thereby improving the sealing performance of the connection between the air inlet 2 and the oxygen tube 3. At the same time, it can also prevent dust from accumulating in the gap of the connection, thereby affecting the normal use of the air inlet 2 and the oxygen tube 3.

[0027] In other embodiments, two groups of torsion springs 43 are provided, and both groups of torsion springs 43 are wound around the surfaces of both ends of the rotating rod 42;

[0028] Through this design, the torsion spring 43 can drive both ends of the rotating rod 42 to reset and rotate in the mounting seat 41, preventing one end of the rotating rod 42 from being subjected to excessive force, causing the rotating rod 42 to get stuck when rotating in the mounting seat 41.

[0029] In other embodiments, the stop block 45 is designed in a C-shape, and the outer wall of the threaded rod 44 fits into the inner wall of the stop block 45;

[0030] With this design, the limiting block 45 can limit the threaded rod 44 and achieve the purpose of positioning the nut 46 and the limiting groove 48, thereby making it easier for the staff to rotate the nut 46 into the limiting groove 48.

[0031] In other embodiments, a handle 47 is welded to the outer end surface of the nut 46 , and grooves are formed on both the front and rear end surfaces of the handle 47 ;

[0032] This design can prevent the worker from slipping when using the handle 47.

[0033] In other embodiments, the depth of the limiting groove 48 is half the length of the nut 46, and a soft pad is glued on the surface of the nut 46 facing the limiting groove 48;

[0034] This design can prevent the nut 46 from continuously squeezing the inner wall of the limiting groove 48, causing serious wear of the inner wall of the limiting groove 48, thereby affecting the connection strength between the air inlet 2 and the oxygen tube 3.

[0035] In other embodiments, the threaded area on the surface of the threaded rod 44 is only one-half the length of the threaded rod 44;

[0036] Through this design, the cost of using the threads on the surface of the threaded rod 44 can be effectively saved, thereby improving the utilization rate of the threads on the surface of the threaded rod 44.

[0037] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.
