In figure: 1-syringe, 2-piston, 3-guide bar, 4-spring, 5-hinder position device, 6-tube plug, 7-guide wire, 8-connection tube, 9-puncture needle, 10-graduation mark, 11-locating ring, 12-hold-down nut, 13-probe tube, 14-airway, 15-catheter, 16-pipe close, 17-pipe close lid, 18-spring shaft, 19-extension spring.

Detailed description of the invention

Be described in more detail below in conjunction with the technical scheme of detailed description of the invention to this patent.

Refer to Fig. 1, a kind of department of endocrinology effusion sampler, comprise syringe 1, piston 2 is provided with in described syringe 1, syringe 1 front end is provided with connection tube 8, and connection tube 8 front end is provided with puncture needle 9, and in the middle part of connection tube 8, downside is provided with catheter 15 and airway 14, the lower end of catheter 15 and airway 14 is goed deep in probe tube 13, and probe tube 13 upper end is provided with pipe close 16; The rear end of described syringe 1 is fixed with tube plug 6, and syringe 1 is also provided with resistance position device 5, described tube plug 6 is provided with guide wire 7, and described piston 2 rear end is connected with guide bar 3, guide bar 3 is socketed with spring 4, and guide bar 4 contacts with guide wire 7 inner wall smooth.During use, pull-out resistance position device 5, piston 3 along the extrapolation of guide bar 3 axis direction, forms negative pressure-pumping hydrops in syringe 1 under the effect of spring 4.

Described puncture needle 9 is provided with the graduation mark 10 indicating length, and puncture needle 9 is provided with locating ring 11, and locating ring 11 is provided with hold-down nut 12.The degree of depth punctured as required, moves to locating ring 11 on the corresponding graduation mark 10 of puncture needle 9, uses hold-down nut 12 to fix, can the accurate localised puncture degree of depth, is convenient to medical personnel and operates.

Described connection tube 8 internal cavities is divided into left and right two parts, and the right cavity communicates with airway 14, and left side cavity communicates with catheter 15.

Described probe tube 13 is provided with the graduation mark 10 of sign capacity, pipe close 16 upper end is provided with pipe close lid 17, pipe close 16 has 2 through holes, pipe close lid 17 has the through hole that 2 corresponding with pipe close 16, be provided with spring shaft 18 on the left of pipe close 16, spring shaft 18 is provided with extension spring 19.Spring shaft 18 is through on the right side of pipe close lid, until pipe close lid 17 left contact pipe close 16 on the left of finger push pipe close lid 17, two through holes on pipe close 16 and pipe close lid 17 can be communicated, to insert catheter 15 and airway 14, after having sampled, catheter 15 and airway 14 are extracted, under the effect of extension spring 19, two through holes on pipe close 16 and pipe close lid 17 stagger, and close pipe close 16, in order to avoid outside contamination endocrine liquid.

Operation principle of the present utility model is: the degree of depth punctured as required, locating ring 11 is moved on the corresponding graduation mark 10 of puncture needle 9, hold-down nut 12 is used to fix, point and promote pipe close lid 17 from left side, pipe close lid 17 is exposed with two through holes on pipe close 16, again catheter 15 and airway 14 are penetrated the through hole of pipe close lid 17 and pipe close 16, extend in probe tube 13, when loosing one's grip, under the effect of extension spring 19, pipe close lid 17 moves to left, catheter 15 and airway 14 are fixed tight, then hand-held syringe 1 punctures, be punctured to after determining the degree of depth, pull-out resistance position device 5, piston 3 is extrapolated along guide bar 3 axis direction under the effect of spring 4, negative pressure-pumping hydrops is formed in syringe 1, endocrine liquid is made to enter cavity on the left of connection tube 8 from puncture needle 9, probe tube 13 is entered into again by catheter 15, by indicating the graduation mark 10 of capacity, after sampling amount reaches, take out puncture needle 9, and then hands promotes pipe close lid 17 from left side, catheter 15 and airway 14 are taken out from probe tube 13, then pipe close lid 17 is unclamped, under the elastic reaction of extension spring 19, pipe close lid 17 homing, lead to the hole site on pipe close lid 17 and pipe close 16 staggers, thus close probe tube 13, probe tube 13 is taken away and checks.

Above the better embodiment of this patent is explained in detail, but this patent is not limited to above-mentioned embodiment, in the ken that one skilled in the relevant art possesses, can also makes a variety of changes under the prerequisite not departing from this patent aim.
