Abstract
The invention discloses a sterile catheter sheath. The sterile catheter sheath comprises a sheathing canal, a protective sleeve, an annular steel cap and a sheathing canal seat, and is characterized in that a sealing piece is arranged in the sheathing canal seat, the sealing piece is tightly pressed and fixed at a position of an end port of the sheathing canal seat through a sheathing canal cover, the sealing piece is made of silica gel materials with a certain amount of elastic deformation, a protrusion is arranged on an outer end face of the sealing piece, a cut seam is formed in the middle of the sealing piece, the outer circle diameter of the sealing piece is larger than the diameter of the end port of the sheathing canal seat, when the sheathing canal cover presses the sealing piece, the sealing piece is inwards deformed to be in an arc shape under the action of the sheathing canal cover and the inner wall of the end port of the sheathing canal seat, problems of blood leaking and oozing in existing common catheter sheaths are solved by the sterile catheter sheath, sealing effects are further good and reliable during usage, the safe and convenient catheter sheath can be provided for coronary artery interventional operations, the unique sealing piece is in a design of preventing oozing and leaking, blood oozing can be prevented, other medical instruments can conveniently pass through the sterile catheter sheath, and the sterile catheter sheath is suitable for all femoral artery sheaths and radial artery sheaths.
Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, relate in particular to a kind of sterile catheter sheath for auxiliary interventional therapy.
Background technology
As the supplemental pilot apparatus of arteriovenous intervene operation, catheter sheath plays an important role in interventional therapy.Particularly disposable sterile catheter sheath, be the external auxiliary consumptive material of cardiovascular intervention diagnosis and treatment, in PTCA plasty, catheter sheath is stayed in arteries, set up blood vessel and extraneous interface channel, to cardiovascular is got involved to contrast examination, cardiovascular expansion or placing rack.Catheter sheath mainly comprises sheath pipe and the system two large divisions of collateral branch conventionally, in sheath pipe, conventionally comprise an important leakage-resistant device, this leakage-resistant device can effectively reduce the loss of blood in operation process, in a lot of application, this leakage-resistant device embodies with the form of haemostatic valve, it is generally a thin silica gel piece, is arranged on the channel attached position of sheath pipe rear end and cannula cavity, after sheath pipe lid compresses, reaches sealing function.But, after extracting in seal wire and dilator process, extracting seal wire and dilator and in to angiography therapeutic process, easily cause leakage blood, there is drawback.
Summary of the invention
The present invention, on the basis of above-mentioned drawback situation, provides a kind of novel sterile catheter sheath, and this catheter sheath has solved the problem of existing common conduit sheath leakage blood, oozing of blood, and the sealing effectiveness in use procedure is better, more reliable.
A kind of sterile catheter sheath of the present invention, comprise: sheath pipe, protecting pipe, annular steel cap, sheath base, described annular steel cap device is in sheath base inside, sheath base tail end has sheath pipe by protecting pipe device, it is characterized in that: sheath base is in-built is equipped with a diaphragm seal, by sheath pipe lid, sealing sheet is pressed abd fixed on to the port of sheath base.
Described diaphragm seal is silica gel material, there is certain elastic deformation amount, sealing sheet is provided with projection on outer face, middle part is provided with joint-cutting, joint-cutting can be cross, rice font, linear type or shaped form, projection can be semicircular arc or boss shape, priorly be, the outside diameter of sealing sheet is larger than the diameter of sheath base port, when diaphragm seal device is during in sheath base port, the inwall of sheath base port will crush seal sheet, and diaphragm seal inwardly shrinks under squeezing action, make joint-cutting airtight tight, increased the sealing property of diaphragm seal.
Further, when pressing sheath pipe lid, sheath pipe lid inwardly pushes the projection of diaphragm seal end face, thereby crush seal sheet caves inward, diaphragm seal is curved to internal strain under the effect of sheath pipe lid and sheath base port inner wall, so just reserved a part of inside deflection, when catheter sheath, staying intra-arterial is subject under arterial pressure, reserved deflection has absorbed partial pressure, all there will not be leakage blood extracting in seal wire and dilator process or after extracting seal wire and dilator, oozing phenomenon, and to angiography, in therapeutic process, also there will not be leakage blood, oozing phenomenon, strengthened the sealing of this product.
This invention catheter sheath can provide for Percutaneous Coronary Intervention the catheter sheath of a safety convenient, and unique diaphragm seal antiseep design, not only can prevent the generation of oozing of blood but also can make other medical apparatus and instruments facilities pass through, and this product is applicable to all femoral artery sheaths and radial artery sheath.

The specific embodiment
Below in conjunction with drawings and Examples, the present invention is further described.
A kind of sterile catheter sheath of the present invention, comprising: sheath pipe 1, protecting pipe 2, annular steel cap 3, sheath base 4, is characterized in that: sheath base 4 is in-built is equipped with a diaphragm seal 5, by sheath pipe lid 6, sealing sheet 5 is pressed abd fixed on to the port of sheath base 4.
As shown in accompanying drawing 2, accompanying drawing 3, sealing sheet 5 is silica gel material, is provided with projection 7 on its outer face, and middle part is provided with joint-cutting 8, described joint-cutting 8 can be cross, rice font, linear type or shaped form, and described projection 7 can be semicircular arc or boss shape.
In addition, the outside diameter of sealing sheet 5 is larger than the diameter of sheath base 4 ports, when pressing sheath pipe lid 6, sheath pipe lid 6 inwardly pushes the projection 7 of diaphragm seal 5 end faces, thereby crush seal sheet 5 caves inward, when by pressing sheath pipe lid 6, when diaphragm seal 5 compactings are fixed on to the port of sheath base 4, diaphragm seal 5 is curved to internal strain under the effect of sheath pipe lid 6 and sheath base 4 port inner walls, so just reserved a part of inside deflection, when catheter sheath, staying intra-arterial is subject under arterial pressure, reserved deflection has absorbed partial pressure, all there will not be leakage blood extracting in seal wire and dilator process or after extracting seal wire and dilator, oozing phenomenon, and to angiography, in therapeutic process, also there will not be leakage blood, oozing phenomenon, strengthened the sealing of this product.
Finally it should be noted that: above embodiment only, in order to technical scheme of the present invention to be described, is not intended to limit; Although the present invention is had been described in detail with reference to previous embodiment, those of ordinary skill in the art is to be understood that: its technical scheme that still can record aforementioned each embodiment is modified, or part technical characterictic is wherein equal to replacement; These modifications or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of various embodiments of the present invention technical scheme.
