Abstract
The present invention relates to a kind of aortic perfusion pipes of the flexible hemostasis ring of band, belong to the field of medical instrument technology.The aortic perfusion pipe of the flexible hemostasis ring of band of the present invention includes aortic perfusion tube body, fixed ring, elastomer, soft pressure ring；The Fixing shrink ring is fixed on aortic perfusion tube body and with aortic perfusion tube body, the softness pressure ring is covered on aortic perfusion tube body and is connect by elastomer with fixed ring, when deformation occurs for the elastomer, the softness pressure ring can be movable on aortic perfusion tube body.The aortic perfusion pipe of the flexible hemostasis ring of band of the present invention when in use, since soft pressure ring has elasticity, without adjusting position, can attach compressing on arterial wall, and oppress arterial wall to prevent from leaking blood around intubation naturally.
Description
Technical field
The present invention relates to a kind of aortic perfusion pipes of the flexible hemostasis ring of band, belong to the field of medical instrument technology.
Background technique
Aortic perfusion pipe is that cardiopulmonary bypass surgery routinely uses one of consumptive material.The positioning ring of existing aortic perfusion pipe
Need temporarily to install before use, or need to according to aorta diameter size adjusting position, use it is extremely inconvenient, and without hemostasis function
Energy.
Summary of the invention
The present invention solves the above problem by the improvement to existing aortic perfusion pipe structure.
The present invention provides a kind of aortic perfusion pipe of the flexible hemostasis ring of band, the active of the flexible hemostasis ring of band
Arteries and veins intrusion pipe includes aortic perfusion tube body, fixed ring, elastomer, soft pressure ring；The Fixing shrink ring is in aortic perfusion
It is fixed on tube body and with aortic perfusion tube body, the softness pressure ring covers on aortic perfusion tube body and passes through elasticity
Body is connect with fixed ring, and when deformation occurs for the elastomer, the softness pressure ring can live on aortic perfusion tube body
It is dynamic.
The present invention be preferably the soft pressure ring material be polyvinyl chloride, nylon, polyurethane, polyether-ether-ketone, polyethylene,
At least one of polyolefin and polypropylene.
The present invention is preferably that the material of the elastomer is polyvinyl chloride, nylon, polyurethane, polyethylene, stainless steel and nickel
At least one of titanium alloy.
The present invention is preferably that the elastomeric ring is wound on aortic perfusion tube body, and one end connect with fixed ring, is another
One end is connect with soft pressure ring.
The invention has the following beneficial effects:
1. the aortic perfusion pipe of the flexible hemostasis ring of band of the present invention is when in use, since soft pressure ring has bullet
Property, it is not necessarily to adjusting position, compressing can be attached naturally on arterial wall, prevents from leaking blood around intubation.
2. the aortic perfusion pipe of the flexible hemostasis ring of band of the present invention can also adjust slotting again after suture is fixed
Tip end enters the distance of blood vessel.
Detailed description of the invention
2 width of attached drawing of the present invention,
Fig. 1 is the structural schematic diagram of the aortic perfusion pipe with flexible hemostasis ring described in embodiment 1；
Fig. 2 is the structural schematic diagram of the aortic perfusion pipe with flexible hemostasis ring described in embodiment 2；
Wherein, 1, aortic perfusion tube body, 2, fixed ring, 3, elastomer, 4, soft pressure ring.
Specific embodiment
Following non-limiting embodiments can with a person of ordinary skill in the art will more fully understand the present invention, but not with
Any mode limits the present invention.
Embodiment 1
A kind of aortic perfusion pipe of the flexible hemostasis ring of band, the aortic perfusion pipe of the flexible hemostasis ring of band include
Aortic perfusion tube body 1, fixed ring 2, elastomer 3, the softness pressure ring 4 made of polyvinyl chloride；
The elastomer 3 is 4 sheet elastomers made of nylon；
2 sets of the fixed ring is on aortic perfusion tube body 1 and fixed with aortic perfusion tube body 1, the softness
4 sets of pressure ring on aortic perfusion tube body 1,4 sheet elastomers are equally distributed on aortic perfusion tube body 1,
And one end of the sheet elastomers is connect with fixed ring 2, the other end is connect with soft pressure ring 4；
When deformation occurs for 4 sheet elastomers, the softness pressure ring 4 can be on aortic perfusion tube body 1
Activity.
Application examples 1
The application method of aortic perfusion pipe described in embodiment 1 with flexible hemostasis ring are as follows: when in use, will be described solid
Determine after ring 2 is sutured in blood vessel surface, deformation occurs for 4 sheet elastomers, and the softness pressure ring 4 tightly fits in blood vessel table
Blood is leaked to prevent from being intubated surrounding in face, when needing to adjust the depth of cannula tip insertion artery in art again, manually adjusts intubation
, since 4 sheet elastomers exist, still can guarantee that the soft pressure ring 4 tightly fits in blood vessel surface always.
Embodiment 2
A kind of aortic perfusion pipe of the flexible hemostasis ring of band, the aortic perfusion pipe of the flexible hemostasis ring of band include
Aortic perfusion tube body 1, fixed ring 2, elastomer 3, the softness pressure ring 4 made of low density polyethylene (LDPE)；
The elastomer 3 is stainless steel spring；
2 sets of the fixed ring is on aortic perfusion tube body 1 and fixed with aortic perfusion tube body 1, described stainless
Steel spring covers on aortic perfusion tube body 1, and 4 sets of the pressure ring of softness is on aortic perfusion tube body 1, the stainless steel
One end of spring is connect with fixed ring 2, the other end is connect with soft pressure ring 4；
When the stainless steel spring is compressed, the softness pressure ring 4 can be movable on aortic perfusion tube body 1.
Application examples 2
The application method of aortic perfusion pipe described in embodiment 2 with flexible hemostasis ring are as follows: when in use, will be described solid
Determine after ring 2 is sutured in blood vessel surface, the stainless steel spring is compressed, and the softness pressure ring 4 tightly fits in blood vessel surface
It prevents from leaking blood around intubation, when needing to adjust the depth of cannula tip insertion artery in art again, manually adjusts intubation,
Since the stainless steel spring exists, it still can guarantee that the soft pressure ring 4 tightly fits in blood vessel surface always.
