Description

The super selection foley's tube of one kind

Technical field

The utility model relates to foley's tube technical field, specially a kind of super selection foley's tube.

Background technique

Clinically, we are often used interventional technique, using conduit, chemotherapeutic or suppository are injected blood vessel, arrived with blood flow Up to targeting moiety.Conventional use of interposing catheter is coarseer, it is very thin for some diameters and (or) blood vessel of complexity out of shape, routinely Conduit cannot be introduced into, that is, allow to enter using ultra-fine conduit, and intubation difficulty is but very big, also, injects medicine using ultra-fine conduit The efficiency of product is very low.

When interventional therapy, we generally select thick conduit to be introduced into big blood vessel, the support of thick conduit are then utilized, thick It is inserted into fine duct in conduit, carries out ultra-fine selection and enters target blood.But for the thin blood vessel of some complexity out of shape, intubation is difficult Degree is very big, and from conduit to the resistance of intravascular injection therefore big, low efficiency causes operating difficulty to increase, and the time extends.

Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

In the description of the present invention, it should be understood that term " longitudinal direction ", " transverse direction ", "upper", "lower", " preceding ", The orientation or positional relationship of the instructions such as " rear ", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outside" be based on Orientation or positional relationship shown in the drawings is merely for convenience of description the utility model, rather than the dress of indication or suggestion meaning It sets or element must have a particular orientation, be constructed and operated in a specific orientation, therefore should not be understood as to the utility model Limitation.

Referring to Fig. 1, the utility model provides a kind of technical solution: the super selection foley's tube of one kind, including outer tube 1, outside Lubricant layer made of silicone oil material is smeared in the outside of pipe 1, and a length of 4 to 6 millimeters of the periphery of outer tube 1, the side upper end of outer tube 1 are set There is first interface 2, the side port position of outer tube 1 is equipped with second interface 3, and viscous stick in the inside of second interface 3 has inner tube 4, inner tube 4 The viscous glutinous outer tube 1 of the other end the inside other end, the inside of outer tube 1 and the inside of inner tube 4 both passed through seal wire 5, seal wire 5 it is another One end is equipped with conductive filament head 8, and the two sides of outer tube 1 have been respectively communicated with the first sacculus 6 and the second sacculus 7, the catheter body between two sacculus On be provided with a side opening.Be respectively arranged with developing mark at proximal balloon and distal balloon catheter, the size of the first sacculus 6 with The size of second sacculus 7 is identical, and reaches being equidistant for hollow interface 9, and hollow interface 9 is made of silica gel material, empty A length of 2 to 3 millimeters of the periphery of heart interface 9, after the expansion of the first sacculus 6, the first sacculus 6 of expansion is fitted closely with vascular wall, can Blood is blocked to be flowed from blood vessel proximal end through this to distal end, while the pressure in the first sacculus 6 is smaller, is not enough to press off by the ball The conduit of capsule, therefore conduit is in unimpeded state herein, after the expansion of the second sacculus 7, the second sacculus 7 of expansion is closely pasted with vascular wall It closes, blood can be blocked to be flowed by blood vessel proximate, fluid can pass freely through conduit at this, while the second sacculus 7 has one Fixed pressure can oppress this section of conduit therethrough, press off conduit, the fluid in conduit cannot pass through this section of conduit by Proximal end flow direction distal end, after two sacculus are all expanded, blood vessel is proximally and distally all closed, the distal end closing of inner tube 4, inner tube 4 Proximal end it is unimpeded.By drug by 4 proximal end of inner tube injection medium position, drug by when 4 part of inner tube at the first sacculus 6 after Afterflow is dynamic, by 4 part of inner tube at the second sacculus 7, then can not continue to flow to the distal end of inner tube 4, the first sacculus 6 and second There is a hollow interface 9 at center between sacculus 7, meanwhile, developed positioning is located at thick blood vessel and the crotch of thin blood vessel Between two sacculus.It when liquid flows through hollow interface 9, can be flowed out through this hole, disperse is thick intravascular between two sacculus, carefully Blood vessel is communicated with thick blood vessel, and liquid flows into thin intravascular immediately, is flowed away to the distal end of thin blood vessel, is reached target location, outer tube 1 Medium position and the medium position of inner tube 4 are communicated with hollow interface 9, and the outside both ends of hollow interface 9 are connected separately with first Gasket 10 and the second gasket 11, the inside of the viscous glutinous outer tube 1 in the side of the first gasket 10, the side of the second gasket 11 are viscous The outside of glutinous inner tube 4.

When the utility model is specifically implemented: first passing through whole portion of the conductive filament head 8 by outer tube 1 when needing injection of medicine Divide the designated position for being introduced into blood vessel, conductive filament head 8 drives seal wire 5 to sequentially pass through second interface 3, inner tube 4 and outer tube 1, then It can be introduced into the inside of outer tube 1 injection water, contrast medium or air, side water, contrast medium or air to second from first interface 2 The position of sacculus 7, the second sacculus 7 are opened at this time, while having pressed off the inner tube 4 of 7 position of the second sacculus, the second sacculus 7 it is interior After the closure of 4 position of pipe, drug is injected from 4 opening portion of inner tube being inserted in second interface 3 at this time, drug can pass through inner tube 4 It is flowed into the inside of inner tube 4, since 4 part of inner tube at the second sacculus 7 is pressed off, so drug is without going past the second sacculus 7 4 part of inner tube at place, when empty gas and water or contrast medium in outer tube 1 continue injection, the expansion of the first sacculus 6 passes through the first sacculus 6 can be bonded with blood vessel, complete the positioning of whole outer tube 1, and due to the influence of two sacculus pressure differences, the first sacculus 6 Pressure the inner tube 4 being extruded herein will not be made to have a stuffy nose, drug flows through the part of hollow interface 9 by inner tube 4, is finally expanded It is dissipated to internal blood vessel.

While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art, It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
