Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, be clearly and completely described the technical scheme in this utility model embodiment, obviously, described embodiment is only this utility model part embodiment, instead of whole embodiments.Based on the embodiment in this utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of this utility model protection.
Refer to Fig. 1, in this utility model embodiment, a kind of effusion extractor for endocrinology department, comprising: syringe needle 1, needle tubing 9 and liquid storage pipe 12.Described syringe needle 1 is provided with locating piece 2, and locating piece 2 is connected on syringe needle 1, and syringe needle 1 is provided with graduation mark; Syringe needle 1 and needle tubing 9 junction are provided with feed liquor check valve 13.Described needle tubing 9 sidewall upper is provided with exhaust check valve 3, and needle tubing 9 sidewall bottom is provided with liquid outlet 10, and liquid outlet 10 is fixedly connected with rubber sleeve 11, and rubber sleeve 11 is tightly connected liquid storage pipe 12, and liquid storage pipe 12 is provided with graduation mark.Just be provided with circular liquid barrier 4 to needle tubing 9 inside above liquid outlet 10, the diameter of liquid barrier 4 is identical with the internal diameter of needle tubing 9, and the periphery of liquid barrier 4 is connected with the inwall of needle tubing 9.Be provided with piston 5 and piston rod 6 in needle tubing 9, piston rod 6 is fixedly connected with handle 7, contributes to the sampling operation of medical worker.Needle tubing 9 Internal back end is provided with baffle plate 6.
This utility model by locating piece 2 can accurately locate syringe needle 1 puncture position, by the scale on syringe needle 1 can determine puncture the degree of depth, make site of puncture and the degree of depth more accurate.Because puncture is traumatic examination, therefore to accomplish once success, reduce the injury to health as far as possible.Liquid storage pipe 12 is provided with graduation mark, can contribute to the volume that medical worker directly obtains liquid storage pipe 12 inner product fluid samples.By judging extract the volume of sample liquid to estimating of the state of an illness, accomplishing that primary sample completes, avoiding repeatedly sampling as far as possible and further injury is caused to patient.
This utility model is provided with feed liquor check valve 13 at syringe needle 1 and needle tubing 9 junction, is provided with exhaust check valve 3 in needle tubing 9 sidewall upper, when extracting hydrops, move after pulling piston 5, feed liquor check valve 13 is opened, and exhaust check valve 3 closes, hydrops enters needle tubing 9, flows into liquid storage pipe 12 by liquid outlet 10.After extraction completes, promote piston 5 and move forward, feed liquor check valve 13 closes, and exhaust check valve 3 is opened, and the air in needle tubing is discharged by exhaust check valve, and piston revert is to initial position.Owing to being provided with feed liquor check valve 13 and exhaust check valve 3 simultaneously, therefore, this utility model can realize repeatedly extracting, and hydrops refluence can not occur.
This utility model is fixedly connected with rubber sleeve 11 with liquid outlet 10 place due to liquid storage pipe 12, in the process of moving after pulling piston 5, needle tubing 9 inner chamber produces negative pressure, endocrine hydrops is drawn out of, the endocrine hydrops extracted out, owing to being subject to the obstruct of liquid barrier 4, all flow in liquid storage pipe 12 through liquid outlet 10, and in needle tubing 9, never air exists, therefore, the pollution of the endocrine hydrops of extraction can not be caused.Because rubber sleeve 11 is fixedly connected with liquid outlet 10, the external diameter of rubber sleeve 11 is substantially identical with the internal diameter of liquid outlet 10, so liquid storage pipe 12 and rubber sleeve 11 slightly firmly can be made to be tightly connected, slightly firmly liquid storage pipe 12 can be taken off after extracting hydrops, avoid hydrops and extraneous contact, Du prevents hydrops contaminated, ensure that the accuracy of assay.
This utility model is provided with baffle plate 6 at needle tubing 9 Internal back end, prevents hydrops in liquid storage pipe 12 too much, has hydrops to overflow environment when taking off liquid trap 12.
Operation principle of the present utility model is:
In use, located the position that will puncture by locating piece, by puncturing after the graduation mark determination paracentesis depth on syringe needle.When extracting hydrops, move, feed liquor one-way valve opens after pulling piston, exhaust check valve closes, and hydrops enters needle tubing, and due to the stop of liquid barrier, hydrops all flows into liquid storage pipe by liquid outlet.Promotion piston moves forward, and feed liquor check valve closes, and exhaust check valve is opened, and the air in needle tubing is discharged by exhaust check valve, and piston revert is to initial position.After completing sampling, slightly firmly take off liquid storage pipe.
To those skilled in the art, obvious this utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or basic feature, can realize this utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in this utility model.Any Reference numeral in claim should be considered as the claim involved by limiting.
In addition, be to be understood that, although this description is described according to embodiment, but not each embodiment only comprises an independently technical scheme, this narrating mode of description is only for clarity sake, those skilled in the art should by description integrally, and the technical scheme in each embodiment also through appropriately combined, can form other embodiments that it will be appreciated by those skilled in the art that.
