Description

Bacterial filter for pulmonary function test

Technical Field

The utility model relates to a filter technical field, in particular to bacterial filter of pulmonary function inspection usefulness.

Background

When the personnel are detecting the pulmonary function, need hold the inlet end of detector with the mouth and blow, the inlet end of current detecting instrument does not have disinfection, filter equipment, and every personnel that wait to detect use the same inlet end of interior disinfection to blow, the germ infection of easy appearance or respiratory track.

The bacterial filter for lung function examination disclosed in patent No. CN201020216055.3 is disposable, and when in use, the bacterial filter is inserted into or sleeved on a sensor interface of a lung function examination instrument, so that cross infection of respiratory tract germs among subjects can be avoided, the sensor is prevented from being polluted, and the service life of the sensor is prolonged.

Although this device can filter the gas blown out by a person, the device has been proposed as a bacterial filter for lung function examination, because the filter medium contained in the housing filters the gas, which affects the speed of gas flow and the data on the detection of the lung capacity of the person.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a main aim at provides the bacterial filter of pulmonary function inspection usefulness, can effectively solve the problem in the background art.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

bacterial filter that pulmonary function inspection was used, including filtering box body, cup jointing pipe and seaming mouth, filter box body inside installs the bull stick and the bull stick outside through the mounting groove and installs the filtration adsorption plate through the mounting groove, filter box body one end hot melt and be connected with a connecting pipe and a connecting pipe one end hot melt and be connected with the cup jointing pipe, the inside one side cover of cup jointing pipe is equipped with a sealing washer No. one, filter box body other end hot melt is connected with No. two connecting pipes and No. two connecting pipe pot lids and is equipped with the seaming mouth.

Furthermore, the number of the filtering and adsorbing plates is multiple, and the filtering and adsorbing plates are made of activated carbon materials.

Furthermore, the inner side of the sleeve pipe is provided with a plurality of anti-skid grooves and a plurality of protective grooves.

Further, No. two sealing washers are installed through the mounting groove to No. two connecting pipe one end.

Furthermore, the first connecting pipe and the second connecting pipe are communicated with the filtering box body.

Compared with the prior art, the utility model discloses following beneficial effect has:

1. through setting up the bull stick and filtering the adsorption plate, personnel are when blowing, and the gas flow beats a plurality of filtration adsorption plates rotations in the bull stick outside, filters, adsorbs the gas that the personnel blown out, does not influence the speed that the gas flows.

2. Through setting up a sealing washer and No. two sealing washers, a sealing washer can insert or cover when the detector inlet end at the bell and spigot joint pipe, plays sealed effect between detector and inlet end, and No. two sealing washers play sealed effect between No. two connecting pipes and mouthpiece.

3. Through setting up the protective slot, a plurality of antiskid grooves can prevent that the condition of landing appears when the inlet end outside of detector is cup jointed to the pipe sleeve.
