Detailed Description
The technical solution of the present invention is further illustrated by the following specific examples.
Example one
Three chamber catheters can be dismantled into medicine and seal the joint, including attach fitting 1 and sealing joint 2, attach fitting 1 is connected with three chamber catheters and sealing joint 2 respectively, is equipped with sealing member 3 in the sealing joint 2, and sealing member 3 sets up in sealing joint 2 through elastic component 4, and sealing member 3 is cavity columnar structure, and sealing member 3 both ends are seal structure, and the end of advancing of sealing member 3 is equipped with into medicine hole 5, is equipped with out medicine hole 6 on the 3 lateral walls of sealing member.
The outer surface of the connecting joint 1 is provided with threads, and the connecting joint is connected with the three-cavity catheter and the sealing joint 2 through the threads.
Sealing joint 2 includes the link and advances the medicine end, and the link inboard is equipped with the screw thread and connects 1 phase-match, advances to go up to dismantle to be equipped with sealed lid 7 on the medicine end.
And a sealing ring 8 is arranged on the connecting end, and the sealing ring 8 is matched with the sealing element 3.
The outer wall of the sealing element 3 is provided with a limiting lug 9, the limiting lug 9 is arranged in a groove 10 on the inner wall of the sealing joint 2, and the limiting lug 9 is connected with the groove 10 through the elastic element 4.
Be equipped with sealing layer 11 in the sealing member 3, sealing layer 11 seals sealing member 3 is inside, and sealing layer 11 adopts deformable material.
The quantity of advancing medicine hole 5 is a plurality of, evenly arranges the setting and advances to expect at sealing member 3 and hold.
The aperture of the medicine inlet hole 5 is 2-3 mm.
The working principle of the scheme is as follows, as shown in figures 1-3, the sealing joint 2 is arranged at the connecting joint 1 to realize sealing after the connecting joint 1 is connected with the three-cavity catheter, and the sealing cover 7 is arranged at the medicine inlet end of the sealing joint 2 for sealing when the catheter is not used, so that the potential safety hazard caused by pollution to the medicine inlet is avoided. When the injection needle is used, the needle tube is inserted into the medicine inlet hole 5 and penetrates through the sealing layer 11 to inject medicine liquid, the medicine liquid is stored in the sealing piece 3 and moves downwards by extruding the sealing piece 3, and the medicine liquid flows into the connecting joint 1 from the medicine outlet hole 6 formed in the side wall of the sealing piece 3 to realize medicine inlet. After the needle head is pulled out, the sealing element 3 is pressed to reset through the elastic element 4, and the environment is changed into a sealed environment again.
Preferably, the sealing layer 11 adopts the silica gel material, can be impaled by the syringe needle, can seal again through material deformation after extracting simultaneously, guarantees sealed effect.
