[0002] The stimulation mouthpiece is an important component installed on the stimulation instrument of the Jaeger pulmonary function tester. However, the disassembly process of the stimulation mouthpiece in the prior art is cumbersome and expensive. It needs to be disassembled and disinfected repeatedly, and cannot be used by one person at a time. It is also not an integrated design, because body fluids and saliva will be exhaled when the stimulation spray is exhaled, which will lead to indirect cross infection, which is not good for health. Summary of the invention

[0003] The purpose of the present invention is to provide a disposable excitation mouthpiece for a pulmonary function instrument to solve the problems existing in the prior art.

[0004] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is a disposable excitation mouthpiece for a pulmonary function instrument, comprising an excitation mouthpiece body, one end of the excitation mouthpiece body is provided with an over-shrinkage, a bite is fixedly provided on the over-shrinkage, an interface is provided at the other end of the excitation mouthpiece body, a fixing seat is fixedly provided at the bottom of the excitation mouthpiece body, a medicine inlet interface is provided on the fixing seat, the medicine inlet interface is connected to the interior of the excitation mouthpiece body, and a fixing component is provided on the fixing seat.

[0005] Preferably, at least 10 layers of filter membranes are fixedly disposed in the interface.

[0006] Preferably, the fixing assembly is a buckle and a locking track, the buckle is arranged on the diagonal bottom of the fixing base, and the locking track is arranged on the bottom of the fixing base.

[0007] Preferably, a plurality of anti-slip strips are fixedly provided on the bite.

[0008] Compared with the prior art, the advantages and positive effects of the present invention are:

[0009] The present invention is not only compact in size, but also integrates three parts into one, which does not require complicated installation and disassembly, thereby reducing clinical operation pressure. Most importantly, it has high cost performance, can be used by one person, and minimizes the possibility of cross infection. It is easy to use, enhances practicality, and brings great convenience.

[0017] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0018] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0019] In this embodiment, Figure 1-5 As shown, the specific design of the above-mentioned key components is described in detail below: a disposable excitation mouthpiece for a pulmonary function instrument, comprising an excitation mouthpiece body 1, one end of the excitation mouthpiece body 1 is provided with an over-shrinkage 2, the over-shrinkage 2 is shrunk downward, which is conducive to the bite of the human mouth and avoids mouth damage, a bite 3 is fixedly arranged on the over-shrinkage 2, the other end of the excitation mouthpiece body 1 is provided with an interface 5, at least 10 layers of filter membranes 10 are fixedly arranged in the interface 5, a fixing seat 6 is fixedly arranged at the bottom of the excitation mouthpiece body 1, a drug inlet interface 9 is arranged on the fixing seat 6, the drug inlet interface 9 is connected to the inside of the excitation mouthpiece body 1, and a fixing component is arranged on the fixing seat 6.

[0020] The fixing components are buckles 7 and locks 8. Buckles 7 are arranged at the bottom diagonal of the fixing seat 6, and locks 8 are arranged at the bottom of the fixing seat 6. A plurality of anti-slip strips 4 are fixedly arranged on the bite 3. The bite 3 is elliptical and has two anti-slip strips 4. The medicine inlet interface 9 is vertically fixed to the fixing seat 6 and closely fits the machine end. Two buckles 7 are designed at the diagonal bottom of the fixing seat 6 and fixed to the machine. One of the buckles 7 is designed as a lock type, which is more stable, and the other buckle is open in the lumen, so that the probe at the machine end can detect the pressure of the exhaled gas more accurately. The filter membrane 10 is used to filter saliva and bacteria, thereby preventing cross infection. After the mounting surface of the excitation mouthpiece of the disposable pulmonary function instrument is aligned with the corresponding buckle 7, the buckle 7 is placed in the groove of the machine, and the buckle can be fixed to the machine by rotating it to embed it into the lock. Then the medicine cup is screwed into the medicine inlet interface 9 to start operation.

[0021] Working principle: The stimulation mouthpiece is installed on the stimulation instrument of the Jaeger pulmonary function meter as a middle partition and a drug inlet vent. The pressure detected from the probe in the lumen can be used as a reference data for clinicians to detect lung function. Disposable products are convenient for clinical use, because body fluids and saliva will be exhaled when the stimulation spray is exhaled, which will greatly increase the infection rate and prevent cross infection. Using a disposable stimulation mouthpiece for a pulmonary function meter can greatly avoid such problems.
