Description

Technical Field

[0001] The utility model relates to the technical fields of lung function test, swimming, diving and special working environment, and in particular to an anti-falling nose clip. Background Art

[0002] During a pulmonary function test, patients are required to breathe completely through their mouths, with their nostrils completely clamped shut to ensure that air in the lungs can only be exhaled through the mouth. A specific sensor then measures lung function. A nose clip is a common tool used in pulmonary function tests.

[0003] During routine pulmonary function tests, the patient's nasal cavity is first clamped with a nasal clip, and then the patient is asked to exhale as hard as possible through the mouth. However, some patients use improper methods when performing forced exhalation and fail to exhale completely through the mouth, which increases nasal pressure and causes the nasal clip to fall off. Some patients have large and hard noses, and ordinary nasal clips fall off before the exhalation action due to insufficient force. In addition, for children, because these patients have small noses and the force-bearing area of ​​the nose is small, the nasal clip is also easy to fall off. When the above nasal clip falls off, the doctor needs to repeatedly adjust the position of the nasal clip for the patient, which brings great inconvenience to the test. Sometimes the patient is even asked to pinch his nose with his hands, but this will affect the patient's breathing movements.

[0004] Furthermore, the elastic components of existing nose clips are mostly made of plastic, which gradually loses its elasticity after long-term use, making it easy for the clip to fall off during use. In addition, most nose clips rely solely on the clamping force on the nose to prevent the clip from falling off, which is not a firm clamping force and is easy to fall off.

[0005] Therefore, there is an urgent need to design a nose clip that is anti-falling and comfortable to wear to solve the above-mentioned difficulties and pain points of the prior art. Utility Model Content

[0006] In view of this, the purpose of the utility model is to provide an anti-falling nose clip, which improves the clamping firmness and comfort of use, prevents the nose clip from falling off when the patient performs deep inhalation and deep exhalation during lung function testing, thereby preventing the test failure and effectively improving the test pass rate.

[0007] The utility model provides an anti-falling nose clip, comprising:

[0008] A nose clip assembly and an elastic strap; wherein the nose clip assembly comprises: a left nose clip, a right nose clip, a spring, a rotating shaft, and two flexible nose pressing blocks; the left nose clip and the right nose clip are hingedly connected via the rotating shaft; the two flexible nose pressing blocks are fixedly connected to one end of the left nose clip and the right nose clip close to the nose; the two ends of the spring are respectively abutted and connected to the grooves on the side of the left nose clip and the right nose clip away from the nose and the rotating shaft; the function of the spring is to apply torque to the left and right nose clips so that the flexible nose pressing blocks can press the patient's nose tightly.

[0009] The two ends of the elastic band are respectively hingedly connected to the transverse sides of the rotating shaft. The elastic band is put on the patient's head when in use.

[0010] Furthermore, the left nose clip and the right nose clip are both made of plastic, and are integrally molded. The left nose clip and the right nose clip are both provided with a pressing handle at one end away from the nose and the rotating shaft, and the pressing handle of the left nose clip and the pressing handle of the right nose clip are assembled face to face.

[0011] Furthermore, the spring is wound with a metal wire, the diameter of the metal wire is Φ2mm, and the material of the metal wire is spring steel.

[0012] Due to the life of the spring and the reduction of spring force during long-term use, the spring can be replaced at any time, and springs of different strength models can also be replaced.

[0013] Furthermore, the flexible nose block is rectangular in shape and can be replaced with various specifications to suit the shape of the patient's nose and adapt to noses of different shapes and sizes. When the flexible nose block clamps the nose, the nose clamp is not easy to rotate.

[0014] Furthermore, the elasticity of the elastic band is adjustable, and can be adapted to the use of different groups of people, thereby achieving both comfortable wearing and preventing the nose clip from falling off.

[0015] When the flexible nose clamp clamps the patient's nose and the elastic band is put on the patient's head, it can effectively prevent the nose clamp from falling off when the patient takes deep inhalation or exhalation.

[0016] Furthermore, the left nose clip and the right nose clip are made of either medical-grade PP plastic or medical-grade PC plastic, or a combination of the two.

[0017] Furthermore, the flexible nose pressure block is made of medical-grade silicone rubber.

[0018] Furthermore, the elastic band is an elastic band for medical supplies. The pH value of the elastic band for medical supplies is between weakly acidic and neutral, which will not cause itching on the skin and will not destroy the weakly acidic environment of the skin.

[0019] Furthermore, the elastic band is made of jacquard polyester.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] The anti-drop nose clip provided by the utility model uses an elastic band to improve the clamping firmness, which can effectively prevent the nose clip from falling off during use. The spring, flexible nose pressure block and elastic band of the nose clip component can be replaced or adjusted, and can be quickly disassembled and assembled, which can adapt to the use of most patients. The anti-drop nose clip uses a lightweight material, is easy and comfortable to wear, and improves the user experience. The utility model can prevent the nose clip from falling off when the patient performs deep inhalation and deep exhalation movements during pulmonary function testing, which may cause test failure, and effectively improve the test pass rate.
