External screw thread form internal and external threads and coordinate, dilator tube is coordinated by above-mentioned internal and external threads and is fixed on the inside of catheter sheath.We
Case improves the convenience that catheter sheath is used, safeguarded using above-mentioned package assembly.
In clinical practice, the effect of the haemostatic valve of catheter sheath is the unsuitable outflow of anti-Hemostatic Oral Liquid, but existing is worn
The haemostatic effect of cellular type haemostatic valve is not good.In order to improve the haemostatic effect of haemostatic valve, this programme employs positive and negative cross plug knot
Structure, haemostatic valve enables that opening is sufficiently large and had not only caused that conduit was smooth and intert but also can guarantee that sealing using positive and negative cross cutting profile
Property, that is, the plug that stops blooding is that, with certain thickness elastic packing film, the center of the plug that stops blooding is provided with cross and penetrates gap, is expanded
Prop pipe head end penetrates the inside that catheter sheath is penetrated in gap from cross, and when dilator tube is inserted, cross gap can be with
It is allowed to pass through and twine to tie up to play a part of sealing thereon, when pipe extraction is expanded, cross gap closes automatically in case hemostasis
Liquid flows out.Further, in order to improve the sealing effectiveness of cross plug, dilator tube is facilitated smoothly to enter catheter sheath, this programme
Employ tapered cross and penetrate gap, i.e., front wide and rear narrow gap interface, that is, the cross in the outside in plug center of stopping blooding
The cross for penetrating the inner side of the A/F more than the hemostasis plug center in gap penetrates the A/F in gap, this knot
Structure expansion pipe enter it is fashionable have benefited from the outside of it opening wide and can smoothly insert, expand have benefited from when pipe is exited it is narrow on the inside of it
It is open and preferable sealing effectiveness can be played.
For the sealing for improving the bonding strength of sheath and sheath connection sleeve pipe and be connected, company of this programme in sheath
Connect end and be provided with and strengthen bushing, be i.e. gland extruding sheath tubular construction, the sheath that is connected by of sheath and sheath seat is enclosed within metal tube and squeezes
It is pressed onto in sheath block hole and plays a part of connection and sealing, the structure bonding strength is high and connector is not damaged.That is sheath
Insertion sheath connection sleeve pipe in one end in be arranged with metal liner, metal liner inserts in sheath connection sleeve pipe sheath
One end is pressed on the inwall of sheath connection sleeve pipe to be formed and seals fixedly sleeved.Further, sheath company is stretched out in order to strengthen sheath
The part of female connector pipe will not bend easily, the one end and sheath pipe connector sleeves of this programme in sheath insertion sheath connection sleeve pipe
Flexible anti-folding protecting pipe is also arranged between the inwall of pipe, the anti-folding protecting pipe of elasticity stretches out sheath connection sleeve pipe, elastic anti-folding sheath
Pipe prevents sheath from being bent in the exit of sheath connection sleeve pipe.Metal liner is anti-with elasticity to roll over being used in combination for protecting pipe
Effect improves stability and security that sheath is connected with sheath connection sleeve pipe.
This programme it is above-mentioned it is improved on the basis of also carried out other optimization designs.Sheath head end using Rouno Cormer Pregrinding Wheel,
The head design of Small Taper, i.e. sheath tube end Rouno Cormer Pregrinding Wheel structure, the end shape of sheath use great circle angular shape, are allowed to passing through
Obstruction will not be produced when skin and blood vessel.I.e. sheath head end is the frustum cavity configuration of Small Taper, the frustum chamber knot of above-mentioned Small Taper
Structure improves sheath head end with skin and intervascular unsuitable scraping effect.It is improved in stopcock structure, using rotation
The narrow mating surface structure of plug valve, the valve element of plug valve is shorter with valve body length of fit, substantially reduces the dynamics of switching spool, and feel is more
Comfortably.The company of adhering with epoxy resin technique, i.e. expander epoxy resin technology, expander and dilator tube is used on expander
Connect and use epoxy bond, with firmness higher.Pass through epoxy i.e. between the tail end of dilator tube and expander connecting seat
Resin bonding is fixed.In order to fix its position when catheter sheath is used, operation is set more to facilitate, this programme connects in side branch
The lateral wall of female connector pipe is provided with the flexibly positioned earrings of catheter sheath, is fixed on catheter sheath by the flexibly positioned earrings of catheter sheath and sets
On fixed position.Improve above and all enhance convenience and the security that catheter sheath is used.
The catheter sheath of this programme is mainly used in PTCA operations, is that all kinds of conduits set up service aisle into human body.Product
Expander insertion sheath is together put when using, rotation guiding threads are fixed, insert blood vessel, expansion is taken out in sheath insertion afterwards in place
Pipe, leaves sheath and releases blood discharge air as service aisle, then Unscrew plug valve, is then inserted into angiography catheter etc.
Other medicine equipments.Based on above operation principle, the catheter sheath device of this programme use the catheter sheath structure of detachable assembling with
It is easy to use, safeguards, the haemostatic effect of haemostatic valve is improved using positive and negative cross plug structure, using metal liner and elastic anti-folding
Protecting pipe is used in combination the stability and security that improve connection, and other adaptability designs relaxing of improving that product uses
Appropriateness, security and convenience.Based on above feature, the catheter sheath device of this programme has substance compared to existing catheter sheath
Feature and progress.
The catheter sheath device of this programme is not limited to the content disclosed in specific embodiment, the technology occurred in embodiment
Scheme can be with individualism, it is also possible to mutually include, the letter that those skilled in the art make according to this programme combination common knowledge
Single alternative falls within the scope of this programme.
