Abstract
The utility model relates to a breathing sampler for collecting breathing air specimens and belongs to the technical field of medical appliances. The breathing sampler comprises a hollow sampling tube, one end of the hollow sampling tube is an air inlet and the other end of the hollow sampling tube is an air outlet, the air inlet of the sampling tube is connected with a blow torch for blowing air or coughing of patients, the sampling tube is provided with two check valves which lead the breathing air to pass through. As the hollow sampling tube of the breathing sampler of the utility model is provided with two check valves which lead the breathing air to pass through, the air breathed by a patient can smoothly pass through the breathing sampler, and the air from outside is prevented so as to ensure the sampling accuracy; an adsorbent which is used for adsorbing the material from the air breathed out by the patient can be arranged between the two check valves in the sampling tube; the breathing sampler has the advantages of simple structure, convenient and quick use; the sampling process can be realized when the patient blows air by biting the blow torch or coughing, and the breathing sampler can not cause injury and discomfort to the patients.
Description
Technical field
This utility model relates to a kind of respiration sampling instrument of breathing gas sample collection, and it is used for medical diagnosis on disease, belongs to the armarium technical field.
Background technology
In the diagnostic procedure of some disease (especially respiratory tract disease), often need to extract patient's vein blood at present, carry out the chemical examination of some indexs, and result of laboratory test and conventional index are compared, thereby help the doctor to diagnose the illness accurately.The methods for the diagnosis of diseases of this blood count has stronger specific aim and higher accuracy, is used widely in the medical diagnosis on disease field.Since blood count need the amount of adopting patient blood, therefore this diagnostic method need puncture patient's skin, vein blood vessel, and leaves wound, this can bring to a certain degree misery to the patient, dizzy mass formed by blood stasis patient even can fall in a swoon; If medical and health conditions are relatively poor, also may cause cross infection.In today that medical skill is constantly reformed, painless non-invasive therapy has become the main trend of medical skill development, and this methods for the diagnosis of diseases of blood count also is faced with challenge.
The applicant dreams up a kind of novel disease (especially respiratory tract disease) diagnostic method, promptly the material and the content thereof that contain in patient's breath is analyzed, thereby is obtained corresponding index, for diagnosis provides foundation and reference.But also there is not this dedicated devices that is used to gather the breathing gas sample at present.
Summary of the invention
The purpose of this utility model is: the main weak point at above prior art exists proposes a kind of respiration sampling instrument that can gather material in patient's breath.
In order to reach the above object: this utility model respiration sampling instrument, the probe tube that comprises a hollow, described probe tube one end is an air inlet, the other end is the gas outlet, the air inlet of described probe tube connects one and is used for the blow gun that the patient blows or coughs, and has two check valves that allow the exhalation air to pass through in the probe tube.
The beneficial effects of the utility model are as follows: be provided with two check valves that allow the exhalation air to pass through in the hollow probe tube of this utility model respiration sampling instrument, the gas that the patient is breathed out can pass through this respiration sampling instrument smoothly, and stop ambient atmos to enter, guaranteed the precision of sampling; Can be equipped with adsorbent between two check valves in the probe tube, this adsorbent is used for adsorbing patient's breath material, during use, the patient contains the blow gun of this respiration sampling instrument and blow (or cough), the gas that blows out is through behind first check valve, contact with the adsorbent in the probe tube, some materials that contain band in the gas are adsorbed agent absorption, remaining gas and the material that is not adsorbed are discharged probe tube behind another check valve, finished into gatherer process, adsorbent is sent to the laboratory and chemically examines.This respiration sampling instrument is simple in structure, easy to use, quick, the patient only need contain blow gun and blow (or cough), can realize gatherer process, and can not cause any wound and sense of discomfort to the patient, therefore this utility model respiration sampling instrument can be competent at the collection of patient respiratory gas sample, is used for disease (especially respiratory tract disease) diagnosis.
Description of drawings
Below in conjunction with accompanying drawing this utility model is further described.
Fig. 1 is the structural representation of this utility model embodiment one.
Fig. 2 is the structural representation of this utility model embodiment two.
The specific embodiment
Embodiment one
The present embodiment respiration sampling instrument as shown in Figure 1, it comprises the probe tube 1 of a hollow, probe tube 1 one ends are air inlet 11, the other end is gas outlet 12, the air inlet 12 of probe tube 1 connects a blow gun 2 that is used for patient's air blowing (or cough), has two check valves 3,4 that allow the exhalation air to pass through in the probe tube 11.
Among the embodiment as shown in Figure 1, be equipped with adsorbent 5 between probe tube 1 interior two check valves 3,4 of the present utility model, adsorbent can adsorb the material in patient's breath, and adsorbent can have multiple choices, and the most common is exactly activated carbon.In the present embodiment, the probe tube 1 of hollow is a L type pipe, and blow gun 2 is the straight pipe type blow gun.
Embodiment two
The present embodiment respiration sampling instrument as shown in Figure 2, the probe tube 1 of hollow is a straight tube, blow gun 2 is for having the blow gun of L type folding pipe.All the other labels are referring to Fig. 1 among Fig. 2.Probe tube adopts the straight tube form, and so not only structure is simpler, and compares with the L shaped pipe that is fit to collection gas, and the adsorbent in the take-off pipe is obviously also more convenient; The probe tube of the straight tube form volume that takes up space is less, transportation and preserve all comparatively convenient.In addition, the outer end of blow gun is greater than the inner, blows or the easier sampler that enters of mixed airflow during cough thereby can make.
Also have a kind of design may the scope of application wider, promptly probe tube be a straight tube, and blow gun is the straight pipe type blow gun, be more convenient for gas-liquid mixed or be the sampling of liquid substantially of this structure.
This utility model respiration sampling instrument also has two seal covers that are used to be enclosed within on probe tube air inlet, the gas outlet, before use, seal cover is enclosed within on probe tube air inlet, the gas outlet, during use, seal cover need be taken off, then blow gun is docked (the employing socket connection is more convenient between blow gun and the air inlet) with air inlet, the patient begins facing to blow gun air blowing (or cough) then; After finishing using (be patient blow or cough finish back), take off blow gun, this seal cover is enclosed within respectively on the air inlet, gas outlet of probe tube, effective like this obstruct in the air admission pipe extraneous under non-working condition guarantees that sampling is not disturbed by extrinsic factor.
In addition to the implementation, this utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation form, all drop on the protection domain of this utility model requirement.
