(3), as Figure 11 and shown in Figure 12, metal reinforced pipe 4 near-ends are connected with big metal reinforced pipe 18.Endoporus after the near-end outer peripheral edges of big metal reinforced pipe 18 are shunk with the near-end of near-end body 3 is inside is connected, and the junction puts in needle stand 1 remote stomidium, by glue near-end body 3 is formed with needle stand 1 remote stomidium and is tightly connected.The internal diameter of big metal reinforced pipe 18 is greater than the external diameter of metal reinforced pipe 4, and metal reinforced pipe 4 near-ends are welded to connect with the distal end inwall of big metal reinforced pipe 18, makes the junction of metal reinforced pipe 4 and big metal reinforced pipe 18 constitute a bigger mouth.Liquid flows out behind big metal reinforced pipe 18 from needle stand 1, arrive 9: one of sacculus by two liquid communication passages and arrive sacculus 9 through metal reinforced pipe 4 endoporus, another cavity 16 between metal reinforced pipe 4 and near-end body 3 forms twin-channel liquid communication passage to sacculus 9.Big metal reinforced pipe 18 adopts rustless steel or Ultimum Ti, and length is 10-100mm, and external diameter is 0.65-1.45mm, and internal diameter is 0.5-1.30mm.The distal end of big metal reinforced pipe 18 can be angular cut, vertical incision or curved incision.
Embodiment exchanges foley's tube fast, as shown in Figure 1, by female cone female Luer needle stand 1, in be provided with the near-end body 3 of metal reinforced pipe 4, the distal component 5 that has a quick exchange mouth 6 connects to form.As shown in Figure 9, the proximal end of metal reinforced pipe 4 is welded with the hook-shaped tinsel 17 of a band circular arc, and metal reinforced pipe 4 is packed into behind the near-end body 3, and tinsel 17 is stuck in needle stand 1 remote stomidium, and metal reinforced pipe 4 is fixedly connected on the needle stand 1.The near-end of near-end body 3 puts in needle stand 1 remote stomidium, by glue near-end body 3 is formed with needle stand 1 remote stomidium and is tightly connected.Metal reinforced pipe 4 forms twin-channel pressure chamber structure with near-end body 3.The internal diameter of near-end body 3 is 1.20mm, and external diameter is 1.50mm, and length is 800mm, and the internal diameter of metal reinforced pipe 4 is 0.80mm, and external diameter is 1.00mm, and length is 850mm.
Comparative Examples, press the quick exchange foley's tube of the structure fabrication single channel pressure chamber structure of embodiment, in order to guarantee equal propelling movement performance, the metal reinforced pipe 4 of the quick exchange foley's tube among the embodiment is replaced to the solid metal silk of a same outer diameter as, other ingredients of conduit remain unchanged, and tinsel and near-end body 3 form single pass pressure chamber structure.The external diameter of solid metal silk is 1.00mm, and length is 850mm.
Earlier to sacculus 9 pressurisings, reach the same outer diameter as size to the sacculus 9 of embodiment and Comparative Examples after, with the pressure removal, record, compares the pressure release time as foley's tube to the time that the liquid in the sacculus 9 all are discharged from from beginning the pressure removal.For the quick exchange foley's tube of embodiment and Comparative Examples, because the size external diameter of sacculus 9 is identical, so the total amount of liquid of required discharge is identical.Therefore under same test environment and test condition, if ignore lumen wall frictional force etc. to the influence of flow rate of liquid, then the pressure release time of foley's tube and the liquid tube chamber sectional area that can pass through is inversely proportional to, and cross-sectional area is big, the quickening of pressure release time.The liquid communication sectional area of the foley's tube of embodiment is that the cavity area between near-end body 3 and the metal reinforced pipe 4 adds that the cavity cross-section of metal reinforced pipe 4 is long-pending, is about 0.85mm
2The liquid communication sectional area of the foley's tube of Comparative Examples is the cavity area between near-end body 3 and the metal reinforced pipe 4, is about 0.35mm
2, two kinds of structures are compared, the foley's tube liquid communication reduced cross-sectional area of Comparative Examples 58.82%.And under the identical precondition of liquid total flow, the cross-sectional area of pressure release time and liquid communication is inversely proportional to, and the pressure release time ratio Comparative Examples of the foley's tube of embodiment will shorten 58.82%.That is to say that under the precondition that guarantees equal propelling movement performance and conduit external dimensions, foley's tube of the present utility model can shorten the pressure release time.
This utility model arranges metal reinforced pipe 4 in near-end body 3, ensured the propelling movement performance of foley's tube.Near-end body 3 forms twin-channel pressure chamber structure with metal reinforced pipe 4, and the channel structure of band metal reinforced pipe has increased the area of section of liquid communication, improves liquid communication speed, has shortened the pressure release time.Because metal reinforced pipe 4 endoporus provide pressure release passage, near-end body 3 is compared near-end body 3 and is had single channel structure wiry with the cavity cross-section area between the metal reinforced pipe 4, near-end body 3 can design forr a short time, the external dimensions of foley's tube can be controlled in scope more suitably like this, to obtain the superior performance of passing through, realize the foley's tube comprehensive performance.
