Description
This utility model belongs to medical infusion device.
At present, the homemade trocar of Shi Yonging mostly is the tissue penetration biopsy clinically, water conservancy diversion is used, the rare transfusion trocar, this product is by sleeve pipe, nook closing member, and syringe adapter is formed, and the puncture rear axle goes out the nook closing member transfusion, can carry out the vein dosing, but after transfusion finished, sleeve pipe can not keep, and can only dosing can not draw blood from syringe interface.
The purpose of this utility model provides a kind of once transfusion and finishes rear sleeve and can keep somewhere in the blood vessel, and transfusion need not repeated puncture once more in a short time, but the both venous transfusion trocars that also can take a blood sample of vein dosing.
This utility model is made up of sleeve pipe, nook closing member, syringe adapter, casing pipe sleeve is on nook closing member, it is characterized in that sleeve pipe is provided with obturator, vertical direction is established two holes on the same cross section of obturator, establishes two holes in the hole, establishes spool in the hole, lid is established in another hole, can be by through hole and and the disjoint passage of this through hole of nook closing member along quill on spool, establishing one, when passage one end communicated with the hole of establishing lid, the other end communicated with sleeve pipe front end inner chamber.
Accompanying drawing 1, this utility model front view
The cutaway view of obturator in accompanying drawing 2, this utility model.
Among the figure: 1 sleeve pipe 2, nook closing member 3, syringe adapter 4, obturator 5, spool 6, through hole 7, passage 8, lid
When using this utility model, rotary spool makes hole and sleeve pipe axially parallel on the spool, and casing pipe sleeve is on nook closing member, and the puncture back is extracted nook closing member out, but connects the syringe venous transfusion by syringe adapter; After transfusion finished, rotary spool was closed into the medicine access sheath and is kept somewhere in the body, connects syringe when infusing once more, and rotary spool opens into that the medicine passage gets final product.When the end back patient that once infuses needed intravenous administration or takes a blood sample, rotary spool was connected the passage two ends on the spool respectively with hole of establishing lid and sleeve pipe front end inner chamber, can realize the purpose of intravenous administration and blood drawing.
