Description
Technical Field
The utility model relates to a prevent tongue jam type breather filter belongs to medical articles for use technical field.
Background
Pulmonary function testing is a common screening program for chronic airway diseases and is also an important method for assessing the safety of surgical operations. In order to prevent cross infection, a disposable respiratory filter is required to be additionally arranged at the front end of the sensor during the current pulmonary function examination, and the disposable filter is used for preventing the pollution of the surrounding environment, the spirometer and the pulmonary function testing instrument caused by possible droplets or atomized particles contained in the exhaled air of the examinee. The examinee needs to bite the mouth piece on the breathing filter and inhale and exhale rapidly with force, and the mouth piece of patient end on the existing breathing filter is oblate and short in length, and a lot of examinees (patients) are very easy to stretch the tongue into the mouth piece in the examination process, block the air blowing channel, cause the expiratory airflow to be limited, interrupted, leak gas and the like, and can not cooperate to finish the examination. If the length of the seam is increased on the filter, the amount of dead space will increase.
Disclosure of Invention
The to-be-solved technical problem of the utility model is: in the process of pulmonary function examination, the problem of blocking the mouth-piece on the breathing filter by the tongue of a patient is avoided.
In order to solve the technical problem, the technical scheme of the utility model is to provide a tongue blockage prevention type respiratory filter, which is characterized by comprising an instrument connecting pipe, one end of which is connected with a pulmonary function instrument, the other end of the instrument connecting pipe is connected with one end of a filter shell, a filtering membrane is arranged in the filter shell, the other end of the filter shell is connected with one end of a bite connecting pipe, the other end of the bite connecting pipe is connected with one end of a bite pipe, and the other end of the bite pipe is connected with a tongue pressing plate; the instrument connecting pipe, the filter shell, the seaming connecting pipe, the seaming pipe and the tongue-pressing piece are of an integrally formed structure.
Preferably, the bite tube is of a flat type structure.
Preferably, the mouthpiece connecting pipe and the mouthpiece pipe are in transition connection through a slope.
Preferably, the tongue depressor is arranged on one side wall of the bite pipe; the shape of the tongue depressor is matched with the shape of the side wall of the bite pipe.
Preferably, the filter membrane is clamped in the filter shell; the filter membrane is located between the two ends of the filter housing.
Preferably, both sides of the filtering membrane are provided with reinforcing ribs, and the reinforcing ribs are fixed on the inner wall of the filter shell.
Preferably, the bite tube is uniformly provided with tooth marks for biting of a patient.
Preferably, the length of the seaming pipe is 2-3 cm.
Preferably, the length of the tongue depressor is 0.5-3 cm.
Compared with the prior art, the utility model has the advantages of it is following:
the utility model discloses a respiratory filter simple structure, reasonable in design, convenient to use more are favorable to the patient to cooperate, reduce the detection degree of difficulty. In the inspection process, the utility model discloses a respiratory filter not only can effectively prevent droplet or the atomizing granule that probably contains in the gaseous of examinee's exhalation, reduces the risk that pollutants such as droplet and sputum brought patient and pulmonary function appearance, and the lower edge of filter patient end has increased the tongue depressor piece of certain length simultaneously, can press the tongue of examinee below, prevents effectively that examinee's tongue from blockking up the filter, can not increase dead space volume again, guarantees the precision and the degree of accuracy of detected data. The subject can also adjust the proper position in the mouth through the teeth marks on the patient end of the filter.

Detailed Description
In order to make the present invention more comprehensible, preferred embodiments are described in detail below with reference to the accompanying drawings.
The utility model provides a tongue blockage prevention type breathing filter, as shown in figures 1-3, which comprises an instrument connecting pipe 1 with one end connected with a lung function instrument, the other end of the instrument connecting pipe 1 is connected with one end of a filter shell 6, the other end of the filter shell 6 is connected with one end of a bite connecting pipe 3, the other end of the bite connecting pipe 3 is connected with one end of a bite pipe 4, and the other end of the bite pipe 4 is connected with a tongue pressing plate 5; the instrument connecting pipe 1, the filter shell 6, the seaming connecting pipe 3, the seaming pipe 4 and the tongue-pressing piece 5 are of an integrally formed structure.
The bite tube 4 is of a flat type structure. The mouthpiece connecting pipe 3 and the mouthpiece pipe 4 are in transition connection through a slope 9, so that the lips of a patient can be conveniently contacted. A filtering membrane 2 is arranged in the filter shell 6, and the filtering membrane 2 is clamped in the filter shell 6; the filter membrane 2 is located between the two ends of the filter housing 6. Reinforcing ribs 7 are arranged on two sides of the filtering membrane 2, and the reinforcing ribs 7 are fixed on the inner wall of the filter shell 6. Teeth marks 8 for occlusion of a patient are uniformly distributed on two flat sides of the bite pipe 4. The length of the bite pipe 4 is 2-3 cm; the length of the tongue depressor 5 is 0.5-3cm, preferably 2 + -0.5 cm. The tongue depressor 5 is arranged on one side wall of the bite pipe 4; the shape of the tongue 5 matches the shape of the side wall of the mouthpiece 4. The section of the bite pipe 4 is of an oval structure, and the section of the tongue depressor 5 is of a circular arc structure.
The utility model discloses a use as follows:
will the utility model discloses a bite pipe 4 on the respiratory filter is taken tongue depressor 5 to stretch into the patient oral cavity to make tongue depressor 5 press on the patient's tongue, let the patient bite and sting mouth pipe 4, carry out the pulmonary function inspection to the patient through respiratory filter at last.
Because the bite tube 4 is provided with the tooth marks 8, the patient bites on the bite tube 4, and the bite tube 4 is prevented from sliding in the mouth of the patient. The tongue pressing piece 5 is pressed on the tongue of the patient, so that the tongue of the patient is prevented from extending into the bite tube 4, and the smoothness of the breathing filter is blocked.
