Description

A kind of endocrine hydrops sampling tool

Technical field

The utility model relates to the technical field of medical instrument, specifically a kind of endocrine hydrops sampling tool.

Background technique

Making a definite diagnosis and treating for endocrine disorder, it is often necessary to extract chest, the hydrops in abdominal cavity is tested.Most often at present Tool is that hydrops is extracted using puncture needle cooperation syringe, then by the standby inspection of the extruding injecting tube in syringe, by note Emitter will not only consume syringe to the turnover of test tube, be also easy to cause secondary pollution, influence inspection result.In addition, injection product Test tube after liquid is in open state, is easy the pollution by surrounding air or causes to spill leakage for inspection hydrops.

Summary of the invention

That the purpose of the utility model is to provide a kind of sealing effects is good, without secondary pollution, can independently generate negative pressure, without nothing Need the endocrine hydrops sampling tool of syringe.

Used technical solution is the utility model in order to solve the technical problem:

The end cap that a kind of endocrine hydrops sampling tool described in the utility model includes test tube, is mounted on test tube nozzle, The center of the end cap is provided with piston through being fitted with conduit in the inner cavity of test tube, the piston bush on conduit and with Conduit is slidably matched, and the outer end of the conduit outside test tube is equipped with pipe close, and the side of pipe close is connected with pulling-on piece, is interspersed in end The inner end of silk thread in lid is fixedly connected with pipe close, outer end is fixedly connected with pulling-on piece.

Two pulling-on pieces are symmetricly set on the two sides of pipe close, and silk thread is vertical with the axis of conduit.

Due to having adopted above structure, the endocrine hydrops sampling tool before sampling, after by end cap seal, avoid contact with Outside air, while negative pressure can be independently generated by hydrops inspiration test tube, attract without syringe, hidden danger without secondary pollution.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model one embodiment.

Fig. 2 is the planar structure schematic diagram of pipe close and pulling-on piece.

Fig. 3 is the structural schematic diagram of use state.

Specific embodiment

As shown in Figure 1, a kind of endocrine hydrops sampling tool described in the utility model includes test tube 1, is mounted on the pipe of test tube 1 End cap 2 on mouth, end cap 2 are made of the big material of the elasticity such as silica gel or rubber, can directly be buckled in the nozzle of test tube 1 On, utilize the excellent sealing for elastically keeping nozzle.The center of the end cap 2 is set in the inner cavity of test tube 1 through conduit 3 is fitted with It is equipped with piston 4, the piston 4 is sleeved on conduit 3 and is slidably matched with conduit 3, the excircle of piston 4 and the inner wall of test tube 1 Cooperate in piston, is also slided on conduit 3 while piston 4 slides above and below in test tube 1.Conduit 3 positioned at 1 outside of test tube Outer end pipe close 5 is installed, the side of pipe close 5 is connected with pulling-on piece 6, and inner end and the pipe close 5 for being interspersed in the silk thread 7 in end cap 2 are solid Fixed connection, outer end are fixedly connected with pulling-on piece 6, and silk thread 7 is vertical with the axis of conduit 3.As shown in Fig. 2, two pulling-on pieces 6 are symmetrical arranged In the two sides of pipe close 5, pulling-on piece 6 and pipe close 5 are made of soft silica gel or rubber material, and pulling-on piece 6 and pipe close 5 are connected with each other Part collectively form semicircle, the part that pulling-on piece 6 and pipe close 5 are separated from each other respectively has semicircular protrusion, makes its phase It can be with free folding between mutually.

As shown in figure 3, in use, pry open pipe close 5 from the protrusion of pipe close 5 first, expose the external port of conduit 3, and Stream guiding tube 8 and puncture needle 9 are connected in the external port of conduit 3, puncture needle 9 is pierced into after human body, pulls out pulling-on piece 6, pulling-on piece 6 draw 4 uplink of piston by silk thread 7, generate negative pressure in the lower section of piston 4, conduit 3 can attract hydrops by stream guiding tube 8 Into test tube 1.After sampling is completed, stream guiding tube 8 is removed, pipe close 5 is covered again can be reclosed on conduit 3. Since pipe close 5 and conduit 3 are located at the center of end cap 2, as long as the silk thread 7 that rotation pulling-on piece 6 and pipe close 5 can will pull out at this time It is wrapped on conduit 3, is finally stowed in the gap between pulling-on piece 6 and end cap 2.
