Abstract
Can dabbling drug sacculus the present invention relates to one kind, including balloon body, it is that cylindrical conduit, both ends are resilient bladders in the middle part of the balloon body, the diameter of the balloon portion forms protrusion more than cylinder-shaped end, described balloon body one end connects decoction source by conduit, micropore is carried on the outer wall of the conduit, if the micropore is axially disposed on conduit outer wall dried layer, every layer of micropore is uniformly arranged around balloon body axis, and the decoction discharge of all micropores is less than the decoction input quantity of connecting tube in the balloon body.Both ends of the present invention use conical sacculus, when the part is heaved, blocking blood flow, sustained drug can be irrigated, the defects of so as to overcome existing medicinal balloon, ensure that medicine has the sufficient time to contact with vascular wall, medicine will not be lost in, patient only needs the short time routinely to take duplex antiplatelet drug after drug application sacculus, significantly reduces patient mental and material burden.
Description
Technical field
, can dabbling drug sacculus more particularly to one kind the invention belongs to medicament elution technical field of tools.
Background technology
In the past 10 years, with the appearance of bracket for eluting medicament, clinically most sufferers are solved the problems, such as.However,
The formation of advanced thrombus and in-stent restenosis, slow-release medicine coating bracket make endothelium healing time extend, to small vessel disease
Become and the processing of bifurcation lesions relatively limit to and the problem of Post operation need to take duplex antiplatelet drug 1 year etc. it is also tight
The clinical Benefit degree of bracket for eluting medicament is govern again.The appearance of medicinal balloon, successfully overcome these defects of drug stent.
Also, it is noted that after drug application sacculus, patient only needs the short time routinely to take duplex antiplatelet drug,
This also significantly reduces the financial burden of patient.
The content of the invention
The technical problems to be solved by the invention be to provide one kind can dabbling drug sacculus, both ends use conical sacculus,
When the part is heaved, blocking blood flow, sustained drug can be irrigated, ensure that medicine has the sufficient time to contact with vascular wall, make
After the sacculus, patient only needs the short time routinely to take duplex antiplatelet drug, significantly reduces patient mental and material
Burden.
The technical solution adopted for the present invention to solve the technical problems is：There is provided one kind can dabbling drug sacculus, including ball
Capsule main body, it is that cylindrical conduit part, both ends are resilient bladder parts in the middle part of the balloon body, the resilient bladder part
Diameter is more than cylindrical conduit part and protrusion is formed in end, and described balloon body one end passes sequentially through conduit and connecting tube connects
Decoction source is connect, micropore, micropore edge on cylindrical conduit outer wall are carried on the outer wall of the cylindrical conduit part
If axially arranged have dried layer, every layer of micropore is uniformly arranged around balloon body axis, the medicine of all micropores in the balloon body
Liquid stream output is less than the decoction input quantity of connecting tube.
In cone, conical big end is connected the resilient bladder with cylindrical conduit.
In the balloon body expansion process, expanded behind the tail end resilient bladder part in connection decoction source, other end head end
Resilient bladder part first expands.
The conduit is bimetallic tube, and one layer of the bimetallic tube is connected and led to the cylindrical conduit in the middle part of balloon body
Connecting tube connection decoction source is crossed, another layer of the bimetallic tube passes through the resilient bladder part at balloon body both ends, for wearing
Enter seal wire.
The connecting tube is in Y-shaped, and one end that the connecting tube is connected with conduit is the double-decker to match with conduit, institute
State double-decker and form bifurcated in connecting tube medium position.
Beneficial effect
It is an advantage of the current invention that both ends use conical sacculus, when the part is heaved, blocking blood flow, medicine can be held
Continuous perfusion, the defects of so as to overcome existing medicinal balloon, ensure that medicine has the sufficient time to contact with vascular wall, medicine will not be lost in
Thing, patient only need the short time routinely to take duplex antiplatelet drug after drug application sacculus, significantly reduce patient's essence
God and material burden.

Fig. 1 is schematic structural view of the invention.
Fig. 2 is balloon body structural representation of the present invention.
Fig. 3 is sacculus swelling state structural representation of the present invention.
Fig. 4 is close-up schematic view at Fig. 3 of the present invention A.
Embodiment
With reference to specific embodiment, the present invention is expanded on further.It should be understood that these embodiments are merely to illustrate the present invention
Rather than limitation the scope of the present invention.In addition, it is to be understood that after the content of the invention lectured has been read, people in the art
Member can make various changes or modifications to the present invention, and these equivalent form of values equally fall within the application appended claims and limited
Scope.
As shown in Figures 1 to 4, one kind can dabbling drug sacculus, including balloon body 1, the middle part of balloon body 1 is cylinder
Shape conduit portion, both ends are resilient bladder parts, and the diameter of the resilient bladder part is more than cylindrical conduit part and held
Portion forms protrusion, and described one end of balloon body 1 passes sequentially through conduit 2 and connecting tube 3 connects decoction source, the cylindrical conduit portion
Micropore 4 is carried on the outer wall divided, if the micropore 4 is axially disposed on cylindrical conduit outer wall dried layer, every layer micro-
Hole 4 is uniformly arranged around the axis of balloon body 2, and the decoction discharge of all micropores 4 is less than connecting tube 3 in the balloon body 2
Decoction input quantity.
In cone, conical big end is connected with cylindrical conduit part for the resilient bladder part.
In the expansion process of balloon body 1, expanded behind the tail end resilient bladder part in connection decoction source, other end head end
Resilient bladder part first expands.
The conduit 2 is bimetallic tube, and one layer of the bimetallic tube and the cylindrical conduit part at the middle part of balloon body 1 connect
Leading to and decoction source is connected by connecting tube 3, another layer of the bimetallic tube passes through the resilient bladder part at the both ends of balloon body 2,
For penetrating seal wire.
The connecting tube 3 is in Y-shaped, and the connecting tube 3 is that the bilayer to match with conduit 2 is tied with one end that conduit 2 is connected
Structure, the double-decker form bifurcated in the medium position of connecting tube 3.
In actual use, coronary angiography is first carried out, after confirmation needs the coronary artery of progress medicinal balloon processing,
Predilation is carried out in lesion using common sacculus, after being satisfied with to blood vessel dilatation, medicinal balloon is inserted at the Coronary Artery Lesions, expanded
The conical sacculus (implanting saccule at front end first expands, and is expanded after tail end sacculus) of the rear and front end of medicinal balloon is opened, and is confirmed under DSA
Coronary blood flow blocks, and medicament is filled to balloon body 1, because the diameter of the conical lower portion of balloon body 1 is more than cylinder-shaped end shape
, can be by focal zone with being separated in the middle part of sacculus into protrusion, and decoction sprays from micropore 4, decoction can be stranded in this region, so as to
So that decoction fully contacts focal zone, reach therapeutic effect.
