Abstract
The utility model discloses a disposable multifunctional medical specimen collection device which comprises a three-way pipe, wherein the three-way pipe is provided with three interfaces which are an input end interface, an output end interface and a middle interface; the input end interface is connected with a cell suction catheter; the internal diameter of the output end interface is matched with the external diameter of an injection syringe interface, and the external diameter of the output end interface is matched with the internal diameter of a catheter of an electric negative pressure aspirator; and a sealing cover is arranged on the middle interface. The disposable multifunctional medical specimen collection device has various functions and wide practicability, and is convenient to use.
Description
Technical field
This utility model relates to a kind of sample collecting apparatus, and the negative-pressure cell that relates in particular to a kind of disposable lower respiratory tract attracts and the lavation sample collecting apparatus.
Background technology
Respiratory system disease is one of main disease of harm humans health, and its case fatality rate is on the rise in recent years.Clear and definite nosetiology and pathological diagnosis are of great importance for the treatment disease, also are the bases of all research works.The etiological diagnosis of lower respiratory infection in the past, pulmonary carcinoma and phthisical pathological diagnosis are the difficult points of clinical position.
Now by bronchoscopy, particularly biopsy clear and definite nosetiology and pathological diagnosis, make its diagnosis that revolutionary variation take place.But, influence diagnosis rate greatly because the positive rate of biopsy is on the low side and the part patient can not tolerate biopsy.
Obtaining cell and lavation specimen is the another kind of main method of clear and definite its nosetiology and pathological diagnosis, mainly contains two kinds of methods of cytology brush and plastic cement pipe suction at present.
The specimen that cytology brush obtains is few, cell is yielding and positive rate is low, and makes complexity, the cost height, and disposable use is difficult to apply; The suction of plastic cement pipe is because the cytotaxis pipe is the plastic cement pipe, plastic cement tip end is sharper keen, can play the effect of curet sample with the pathological changes bronchial mucosa negative pressure-pumping that adds syringe that rubs back and forth, thereby obtain more many cells composition, avoid brush to seize and got the shortcoming that specimen is less and flushing causes specimen to be diluted, thus the positive diagnosing rate of property pulmonary carcinoma around having improved.The device of plastic cement pipe suction comprises cytotaxis pipe, tee T, bronchoscope, sample harvester.The input end interface of tee T connects the cytotaxis pipe, and outfan interface internal diameter connects syringe.Because the outfan interface of tee T has only internal diameter can connect syringe, so plastic cement pipe suction can only carrying out negative-pressure cell attracts the collection of specimen, function singleness.
The utility model content
This utility model is to provide a kind of disposable multifunction medical sample collecting apparatus, can carry out negative-pressure cell and attract and the lavation collection of specimens.
The medical sample collecting apparatus of the disposable multifunction that this utility model provides, comprise tee T, this tee T has three interfaces: input end interface, outfan interface and middle part interface, input end interface connects the cytotaxis conduit, outfan interface internal diameter and syringe interface external diameter coupling, connect syringe in being used for, it is characterized in that: the catheter diameter coupling of described tee T outfan interface external diameter and electronic vacuum extractor is used for external electronic vacuum extractor.
Described middle part seam has increased seal cover, is used for capping middle part interface, can prevent to pollute the specimen that collects.
In this utility model device, the internal diameter of tee T outfan interface is with the external diameter coupling of syringe interface, outside dimension is with the internal diameter coupling of electronic vacuum extractor conduit, so the outfan interface of tee T can in connect syringe, external electronic vacuum extractor has been realized the multiple function of device, can gather negative-pressure cell and attract specimen, can gather the lavation specimen again, the suitability is wide, and is easy to use.
Description of drawings
Fig. 1 is a three-way pipe structure front view of the present utility model.
Fig. 2 is a three-way pipe structure right view of the present utility model.
Fig. 3 is a workflow diagram of the present utility model.
The specific embodiment
A kind ofly enter or enter lower respiratory tract, obtain cell and lavation specimen, help the device of clear and definite respiratory tract pathology and etiological diagnosis, as shown in Figure 1 through thyrocricoid puncture through bronchoscope.
For the Bronch patient of tolerance, operational approach is as follows:
Tear non-returnable container, if find that by bronchoscopy the diseased region mucosa has hemorrhage festering, then directly from the scope endoporus, insert cytotaxis conduit 2, after this pipe top arrives diseased region, carry repeatedly and insert negative pressure catheter 2 and make its far-end mucosa that constantly rubs, close tee T seal cover 3 then, another termination syringe of tee T perhaps connects electronic vacuum extractor and attracts specimen, takes out this cytotaxis pipe, then specimen is injected in the sample harvester its workflow such as Fig. 3.If the diseased region mucosa does not have hemorrhage festering, then after biopsy, from the scope endoporus, insert cytotaxis conduit 1, behind negative pressure catheter 2 injection normal saline, connect the lavation specimen container and directly carry out lavation.
Can directly enter into lower respiratory tract from the artificial airway for the patient that the artificial airway is arranged, operational approach is the same then.
For not carrying out the patient that bronchoscope does not have artificial air flue again, then operational approach is as follows:
Do thyrocricoid puncture with cricothyroid membrane puncture needle, withdraw from syringe needle after inserting cytotaxis conduit 2 in the pin, keep negative pressure catheter 2 and do and attract and lavation acquisition specimen.
Claims (2)
1. medical sample collecting apparatus of disposable multifunction, comprise tee T (1), this tee T has three interfaces: input end interface (11), outfan interface (12) and middle part interface (13), input end interface (11) connects cytotaxis conduit (2), outfan interface (11) internal diameter and syringe interface external diameter coupling, connect syringe in being used for, it is characterized in that: the catheter diameter coupling of described tee T outfan interface (12) external diameter and electronic vacuum extractor is used for external electronic vacuum extractor.
