Description

Mask type peak speed instrument

Technical Field

The utility model relates to a mask formula peak speed appearance.

Background

The existing vital capacity test usually adopts a peak velocity instrument (also used as a peak velocity meter), the peak velocity instrument is used for testing the peak velocity condition and is used for measuring a pulmonary function index of a patient, the main reaction is the limited degree of the exhaled air of the patient, and the patient can drive a scale cursor to display a specific expiratory flow peak value through blowing by a buccal device (namely an air inlet pipe at the air inlet end of the peak velocity instrument) at the end part of the peak velocity instrument, however, when the peak velocity instrument is used, some persons with facial muscle atrophy, lip muscle defect and other nervous system pathological changes which cause mouth occlusion weakness are not easy to completely cling the mouth part to the air inlet pipe at the air inlet end of the peak velocity instrument, so that the measured value is not accurate.

SUMMERY OF THE UTILITY MODEL

The utility model discloses improve above-mentioned problem, promptly the to-be-solved technical problem of the utility model is that muscle atrophy, lip muscle are defective, other nervous system pathological changes lead to the powerless person of oral area interlock to be difficult to hug closely the oral area completely with the intake pipe of peak speed appearance inlet end when using the peak speed appearance and cause the numerical value of measuring inaccurate.

The utility model discloses a concrete implementation scheme is: the mask type peak speed instrument comprises a peak speed instrument, wherein an air inlet pipe is arranged at the air inlet end of the peak speed instrument, the air inlet pipe is connected with a mask, and one side, facing the air inlet pipe, of the mask is provided with a hole capable of being communicated with the air inlet pipe.

Furthermore, the face guard is cone-shaped and gradually increases from the opening direction to the outer side.

Furthermore, a cannula capable of being inserted into the air inlet pipe extends at the opening of the face mask.

Further, a sealing ring is arranged between the outer surface of the insertion pipe and the inner wall of the air inlet pipe.

Furthermore, the opening of the face mask extends to form a sleeve which can be sleeved into the air inlet pipe, and the sleeve is in snap fit with the air inlet pipe.

Furthermore, a sleeve capable of being sleeved into the air inlet pipe extends from the opening of the face mask, and a sealing ring is fixed on the inner side of the sleeve.

Further, a rubber cover is fixed on the outer side edge of the face mask.

Compared with the prior art, the utility model discloses following beneficial effect has: the utility model discloses simple structure can seal the mouth through the face guard when carrying out the volume of blowing test to the patient of face muscle atrophy to conveniently measure concrete numerical value accurately.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1 to 5, in the first embodiment, the mask type peak velocity apparatus includes a peak velocity apparatus 10, an air inlet pipe 110 is provided at an air inlet end of the peak velocity apparatus, a mask 20 is connected to the air inlet pipe, and an opening 210 capable of communicating with the air inlet pipe 110 is provided at a side of the mask 20 facing the air inlet pipe.

In the first embodiment, a cannula 220 capable of being inserted into the air inlet pipe extends from the opening of the face mask 20.

In this embodiment, the mask is tapered and gradually increases from the opening direction to the outside, so as to cover the mouth, and the size of the mask can generally cover the nose and the mouth with the size of a common oxygen mask, or cover only the mouth with a small area. In order to improve the sealing performance in the process of blowing air flow, a sealing ring 221 is arranged between the outer surface of the insertion pipe 220 and the inner wall of the air inlet pipe, so that the sealing performance is improved, and in addition, the rubber cover 30 is fixed on the outer edge of the face mask, so that the pressure of the outer edge of the face mask on the face can be relieved, and the face mask and the face can be sealed more. When the mask is used, the air volume reserved in the space between the inner wall of the mask and the face due to obstruction needs to be measured in advance to serve as a correction value of a test, and then a tester can know the air blowing volume condition of the mask by blowing air at the mouth part covered by the mask under the condition of the mask through the measurement and calculation of the correction value. The method can measure the air blowing amount even in the conditions of facial muscular atrophy, lip muscle defect, oral occlusion weakness caused by other nervous system diseases and the like.

In the second embodiment, compared with the first embodiment, in the present embodiment, a sleeve 40 capable of being sleeved into the air inlet pipe extends from the opening of the mask, and the sleeve 40 is in snap fit with the air inlet pipe.

In the third embodiment, compared with the first embodiment, in the present embodiment, a sleeve 40 capable of being sleeved into the air inlet pipe extends from the opening of the mask, and a sealing ring 410 is fixed on the inner side of the sleeve, so as to improve the sealing performance.

The utility model discloses if disclose or related to mutual fixed connection's spare part or structure, then, except that other the note, fixed connection can understand: a detachable fixed connection (for example using bolts or screws) is also understood as: non-detachable fixed connections (e.g. riveting, welding), but of course, fixed connections to each other may also be replaced by one-piece structures (e.g. manufactured integrally using a casting process) (unless it is obviously impossible to use an integral forming process).

In addition, the terms used in any aspect of the present disclosure as described above to indicate positional relationships or shapes include similar, analogous, or approximate states or shapes unless otherwise stated.

The utility model provides an arbitrary part both can be assembled by a plurality of solitary component parts and form, also can be the solitary part that the integrated into one piece technology was made.

Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting the same; although the present invention has been described in detail with reference to preferred embodiments, it should be understood by those skilled in the art that: the invention can be modified or equivalent substituted for some technical features; without departing from the spirit of the present invention, it should be understood that the scope of the claims is intended to cover all such modifications and variations.
