Embodiment:

To shown in the accompanying drawing 6, the utility model sampling connects by C and is made of lid D, connecting pipe E, spring F, colloid G, leak-stopping chock plug H, catheter body I and protective sleeve J as accompanying drawing 3; Wherein, this lid D is provided with convex body D1, screw thread D2, inwall D3, track D4, protective D5 and snap ring D6; Connecting pipe E is provided with lug E1, perforation E2; Colloid G is provided with perforation G1; Catheter body I is provided with convex body I1, platform I2 and passage I3; Pipe J1, screw thread J2, connecting portion J3 and socket part J4 in protective sleeve J is provided with; Colloid G places on the platform I2 of catheter body I, the front end of connecting pipe E is equiped with spring F outward, and penetrate in the perforation G1 of colloid G, and this connecting pipe E and with leak-stopping chock plug H fit, lid D engages with the convex body I1 of catheter body I by convex body D1, connecting pipe E is coated in the protective I, and colloid G is pressed together on the platform I2 with inwall D3, the inwall D3 of lid D is provided with for connecting pipe E extension lug E1 and wears track D4, and be provided with screw thread D2 at its lid D top, and its connecting pipe E inside is provided with a passage I3 who is compatible to syringe, and this passage I3 corresponds to the perforation E2 that connecting pipe E front end wears;

The edge mouth place in lid D space is provided with a snap ring D6, when having syringe in its space mutually and pressing down connecting pipe E, lug E1 is attached to the inwall D3 on the lid D, and the track D4 that moves at inwall D3, continue to press at the end at connecting pipe E, to passage I3, this syringe firmly is fastened in snap ring D6 in perforation E2 break-through, and secure connecting pipe E, the action that makes syringe take a sample or to inject;

Protective sleeve J connects socket part J4 with connecting portion J3; be placed in socket part J4 on the protective D5 of lid D; and this socket part J4 tool reelability; when sampling joint C does not use; turn up by the screw thread D2 spiral shell of screw thread J2 and lid D protective sleeve J solid; pipe J1 penetrates in the connecting pipe E in it again, and protection connecting pipe E avoids contacting with air in inside, prevents bacterial infection.

As accompanying drawing 7 to shown in the accompanying drawing 9, before sampling joint C does not have the syringe connection, elastic force by spring F withstands on lid D body inside with connecting pipe E, and be fixed in the lid D by snap ring D6, and closely pressing mutually between leak-stopping chock plug H, perforation E2 and colloid G, keeping a complete airtight conditions, and prevent that the inner blood of catheter body I from leaking outside;

Wherein this no thread syringe K front end is extended with injection head K1, after in injection head K1 penetrates connecting pipe E, produce driving fit and can continue to press down connecting pipe E, when connecting pipe E is not had that thread syringe K engages and when pressing down, move in the track D4 of the inwall D3 of lug E1 on lid D, when connecting pipe E continues to press down, after lug E1 arrives track D4, this injection head K1 attaches driving fit at snap ring D6, and fixedly be fastened on snap ring D6, at this moment, injection head K1 that connecting pipe E is fixed simultaneously makes a strength that presses down, and this injection head K1 presses down connecting pipe E and make it leak-stopping chock plug H and separate colloid G with perforation E2, arrives catheter body I inside, make the injection head K1 can fixedly connected pipe E, and the action that can take a sample or inject.

Shown in accompanying drawing 10 and accompanying drawing 11, there is thread syringe L front end to be provided with spiral shell solid L1, screw thread with spiral shell solid L1 is fixed on the screw thread D2 of lid D, produce the strength that continues to press down when moving admittedly with spiral shell, press down connecting pipe E after injection head L2 and the connecting pipe E driving fit, during admittedly to the end, injection head L2 presses down connecting pipe E makes leak-stopping chock plug H separate colloid G with perforation E2 at spiral shell solid L1 spiral shell, arrive catheter body I inside, the action that have thread syringe L to take a sample or to inject this moment.

As shown in Figure 12; protective sleeve J connects socket part J4 with connecting portion J3; be placed in socket part J4 on the protective D5 of lid D; socket part J4 tool reelability; when sampling joint C did not use, it was solid to have torn protective sleeve J open pass through screw thread J2 and lid D screw thread D2 spiral shell, and interior pipe J1 penetrates in the connecting pipe E; protection connecting pipe E avoids contacting with air in inside, prevents bacterial infection.

As shown in Figure 13, be made as the structure of projection on the colloid G, the elastic force that bulge-structure produced by rubber peaks at lid D inside with connecting pipe E, and closely presses between leak-stopping chock plug H, perforation E2 and colloid G and protect generation one complete airtight conditions, prevents that the inner blood of catheter body I from leaking outside.
