Description
Technical Field
The utility model belongs to the technical field of gaseous sampling, concretely relates to be used for breathing measuring sampling pipeline.
Background
The human breath detection and analysis is an important research direction in the modern medical field, comprises the contents of human mouth and nose airflow, respiratory mechanics, respiratory gas concentration and the like, and is often applied to the aspects of sleep breath detection, human lung function detection, helicobacter dreaming expiration detection, end-expiratory carbon dioxide, anesthetic gas concentration monitoring and the like. In the respiratory detection process, the respiratory gas collected by the equipment often contains water vapor, mucus, dust and other substances, and the substances enter the equipment to cause risks such as inaccurate equipment measurement, cross infection of patients or damage to instrument parts, so that in the respiratory detection, the gas before being sampled and entering the equipment needs to be filtered by impurities to ensure normal operation and accurate measurement of the equipment.
The human body breathing equipment is a real-time and continuous measuring device, the device is connected between the equipment and the mouth and the nose of a patient through a pipeline, the equipment realizes real-time sampling on human body breathing according to a set sampling mode, and the sampling pipeline disclosed by the invention is used for the above description.
The breathing gas sampling pipeline designed by the invention has the characteristics of small volume, high portability, good water removal performance, long service life, small dead space of a gas chamber and the like, and can be used for preprocessing the breathing gas of a human body, so that the breathing signal can be accurately and stably extracted and analyzed.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a sampling pipeline for breathe measurement.
The technical scheme of the utility model is that: the utility model provides a sampling pipeline for breathe measurement, sampling pipeline connects along the first pipeline that the direction of admitting air set up, gas circuit unit, filter unit and second pipeline joint, first pipeline joint jointing equipment end sampling gas air inlet, nasal cavity sampling pipe or gas circuit tee bend adapter are connected to the second pipeline joint, filter unit is filter paper for will remove the external impurity of breathing gas and hold back, be close to the cover is equipped with water storage unit on the gas circuit unit of filter unit one end, water storage unit is used for adsorbing the impurity that the filter unit surface was held back.
Preferably, the air passage unit is an elongated tubular structure.
Preferably, the filter paper is disposed between the outside of the end surface of the water storage unit and the second pipe joint.
The utility model has the advantages that:
1. through set up filter paper in the direction of admitting air, magazines such as can effectively avoid human breathing steam, mucus or dust get into equipment, realize the effective protection to equipment.
2. The water storage unit can adsorb impurity such as filterable moisture, mucus of filter unit surface entrapment, has promoted the life of sampling pipeline.
3. The signals of nasal airflow, respiratory mechanics, respiratory gas concentration, components and the like of a human body can be effectively extracted in real time.

Fig. 2 is a schematic sectional view of the sampling pipeline for respiration measurement according to the present invention.
Detailed Description
The utility model discloses the following will make further detail with the accompanying drawing:
please refer to fig. 1 and fig. 2 for showing, the utility model provides a sampling pipeline for breathe measurement, the first pipeline that sampling pipeline route set up along the direction of admitting air connects 2, gas circuit unit 5, filter unit 3 and second pipeline joint 1, first pipeline connects 2 connecting device end sampling gas air inlets, second pipeline connects 1 and connects nasal cavity sampling pipe or gas circuit tee bend adapter, filter unit is filter paper for keep back the impurity except that breathing gas, be close to the cover is equipped with water storage unit 4 on the gas circuit unit of filter unit one end, water storage unit 4 is used for adsorbing the impurity that filter unit 3 surfaces were held back.
The air path unit 5 is of an elongated tubular structure.
The filter paper is disposed between the outside of the end surface of the water storage unit 4 and the second pipe joint 1.
When this sampling pipeline is sampled to breathing gas, sampling gas passes through nasal cavity sampling pipe or gas circuit tee bend adapter, and via first pipeline joint 2, gas circuit unit 5, filter unit 3 and the order that second pipeline connects 1, get into inside the measuring equipment, and impurity such as mucus, pipeline wall comdenstion water or dust that get into in the gas circuit unit 5 are being held back through filter unit 3, realize the sampling gas preliminary treatment. When signals of respiratory mechanics or oral-nasal airflow and the like are extracted, impurities in the pipeline can be intercepted by the filtering unit 3.
The above description is only a preferred embodiment of the present invention, and all equivalent changes and modifications made according to the scope of the claims of the present invention should be covered by the claims of the present invention.
