Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, the especially a kind of single-lumen ovum pickup device that can collect a large amount of ovums rapidly.
Background technology
In infertility treatment of diseases means, test-tube baby is one of common effective means.At present the ovum process of getting in the test-tube baby operation mainly is to utilize puncture needle that follicle is punctured, then by the vacuum suction mode with the follicular fluid sucking-off, the operating process more complicated.
Summary of the invention
Technical assignment of the present utility model is to provide a kind of single-lumen ovum pickup device at above-mentioned deficiency of the prior art, and this single-lumen ovum pickup device is easy to use, and the negative pressure that can utilize vacuum extractor to produce directly will be steeped liquid and be sucked in the test tube.
The technical scheme that its technical problem that solves this utility model adopts is: a kind of single-lumen ovum pickup device, its structure comprises that the end is provided with the puncture needle and the handle in ultrasonic echo district, in order to realize the purpose of this utility model, collecting pipe, sealing-plug, negative pressure Connection Block and negative pressure connection tube have also been increased in its structure, collecting pipe one end joins by handle and puncture needle, the other end passes sealing-plug, one through hole is set on sealing-plug, one end of negative pressure connection tube and the through hole on the sealing-plug join, and the other end of negative pressure connection tube and negative pressure Connection Block join.
Be outside equipped with protective casing at puncture needle.
Single-lumen ovum pickup device of the present utility model is compared with prior art, reasonable in design, effect convenience, and the negative pressure that can utilize vacuum extractor to produce directly will be steeped liquid and be sucked in the test tube.
Description of drawings
Accompanying drawing 1 is the structural representation of single-lumen ovum pickup device.
The specific embodiment
Explain below with reference to Figure of description single-lumen ovum pickup device of the present utility model being done.
As shown in drawings, single-lumen ovum pickup device of the present utility model, constitute by puncture needle 1, handle 2, collecting pipe 3, sealing-plug 4, negative pressure Connection Block 5 and negative pressure connection tube 6, the end of puncture needle 1 is provided with ultrasonic echo district 7, root joins by handle 2 and collecting pipe 3, the other end of collecting pipe 3 passes sealing-plug 4 and stretches out certain-length, and extension elongation is according to the length setting that is used for collecting the test tube that steeps liquid; Have a through hole in addition on sealing-plug 4, an end of negative pressure connection tube 6 and the through hole on the sealing-plug 4 join, and the other end and negative pressure Connection Block 5 join.
In order to protect the ultrasonic echo district 7 of puncture needle 1 and end thereof, protective casing 8 can be set outside puncture needle 1.
During use, at first one test tube is set, negative pressure Connection Block 5 and negative pressure absorber are joined at sealing-plug 4 places; Then puncture needle 1 is fixed on the B ultrasonic transvaginal probe, and insert vagina thereupon, on the B ultrasonic display screen, promptly can see the image in cellular ovary and ultrasonic echo district, puncture needle end 7 this moment, the doctor just can be according to the puncture needle 1 on this manipulated image probe, the negative pressure of utilizing the negative pressure absorber to form is aspirated each follicle successively, and the bubble liquid of sucking-off enters test tube along collecting pipe 3.
Its processing and fabricating of single-lumen ovum pickup device of the present utility model is very simple and convenient, gets final product according to universal machine processing method processing and fabricating shown in the by specification accompanying drawing.
Except that the described technical characterictic of description, be the known technology of those skilled in the art.
