Description
Technical field
The present invention is to be related to protective case in a kind of tearable body for carrying medicine apparatus, belongs to technical field of medical instruments.
Background technology
In recent years, percutaneous coronary intervention (pci) (percutaneous coronary intervention, PCI) takes
Quick development was obtained, but needs to be delivered to definitely the load medicine apparatus such as medicinal balloon, drug stent in interventional procedure
Lesion locations.
Due to medicinal balloon be by medication coat in balloon surface, when sacculus reaches diseased region blood vessel wall it is softened,
Expansion, when contacting with blood vessel wall inner membrance, the technology of medicine quick release, diversion medicaments in local vessel wall, but medicinal balloon
Medication coat loss in crossing process in intravascular is still the subject matter that current medicinal balloon technology faces.From the number announced
According to display, the medicine of prior art passes through loss rate all more than 20%, and the design of medicinal balloon is cannot to avoid wearing at present
More lose, because the exposed medicine of medicinal balloon and contacting blood, the friction in crossing process with blood vessel, necessarily causes in addition
Medicine is lost.So how medication coat to be protected in course of conveying, when making medicinal balloon reach diseased region work
Effectively discharged again, be the problem of urgent need to resolve.
In addition, drug stent itself is nonelastic, which is by being mounted on sacculus in advance, being delivered to support by foley's tube
At vascular lesion, when balloon expandable to draft diameter after be attached at blood vessel wall by blood vessel wall retraction force, great advantage is release
When registration, radial support power is stronger, can be close to blood vessel wall, be difficult to bounce back and shift after expansion.In order to prevent transportation
It is middle that destruction occurs, it is required to protect sleeve pipe to protect drug stent in packaging process, the guard method is first by medicine
Stake body compresses, and then by the protection sleeve pipe of the stake body insertion certain specification internal diameter of compression, molding is packed after thermal finalization.But
It is that the method has the disadvantage that：Medication coat can be because the reason for rubbing, causes medicine during protection sleeve pipe is installed
Loss, this loss is typically uncontrollable, and the stability of technique can be impacted；This friction is for support simultaneously
And a kind of damage, cause support to be destroyed, the final using effect for affecting product；In addition this friction can cause support and ball
The binding ability of capsule itself weakens, and result in support and easily occurs to slide in course of conveying in vivo, causes the positioning of support to be forbidden
Even support is wandered and causes serious malpractice in vivo.
Also, clinically 70% coronary stenosis Disease has different degrees of Coronary Calcification, blood vessel tortuous and diffusivity
The complex lesions such as pathological changes, medicinal balloon in course of conveying, can occur to rub with conduit, blood vessel wall and complex lesions region in vivo
So that medication coat comes off, and medication coat come off certainly will affect therapeutic effect and can cause Ink vessel transfusing acute embolic and its
The generation of his disease；And drug stent is in vivo in course of conveying, it is susceptible to cradling piece and caused blood is scratched to blood vessel wall
Pipe is damaged, and the de- load phenomenon of support occurs, and the support after de- load is fallen in blood vessel, it will cause fatal risk.
But the external protection before protecting protection of the sleeve pipe to sacculus or support mainly to perform the operation using thermal contraction at present, be
Protection for sacculus or support during logistics transportation and the protection of personnel's maloperation is prevented, for example：Patent
Medicine disclosed in the balloon protective sleeve and CN201520518264 of the balloon catheter for expanding vertebra disclosed in CN200920173162
Thing FirebirdTM；In operation technique, need first manually to remove protection sleeve pipe and then conveyed in vivo, it is impossible to realize to internal
The protection of course of conveying, it is impossible to solve drug stent, medicinal balloon etc. and carry the medicine that medicine apparatus occurs in course of conveying in vivo
Come off, the damage to blood vessel and other various security risk problems, become intervention operator's urgent need to solve the problem.
The content of the invention

Bar tearing strip is between two tear lines.
Preferably, the tear line and tearing strip are along the longitudinally disposed of the distal component.
Preferably, the fixing end of the tearing strip is fixedly connected with the end of distal component, the tearing strip
Axially proximally part direction extension of the free end along distal component.
Used as further preferred scheme, the tearing strip is structure as a whole with distal component.
Preferably, the distal component is the pipe fitting by made by one or more layers macromolecular material.
Used as further preferred scheme, the distal component is elastic or non-resilient pipe fitting.
As further preferred scheme, the macromolecular material selected from silicone rubber, polyurethane, politef, polypropylene,
At least one in polyethylene, nylon, nylon elastomer, polyethylene terephthalate, polyethers.
Used as further preferred scheme, the outer surface of the distal component is coated with lubricity silicon coating or hydrophilic painting
Layer.
Preferably, the proximal piece is solid rod member or hollow pipe fitting.
Preferably, the proximal piece is provided with one or more Marking rings.
Preferably, the load medicine apparatus is that ball expands formula drug stent or medicinal balloon.
Preferably, in the tearable body, protective case also includes handle, the handle and the proximal piece
Head end is connected.
Compared to prior art, the Advantageous Effects of the present invention are：
In the tearable body provided due to the present invention, the distal component of protective case is provided with least two tears of preprocessing
Line and at least one tearing strip, and every tearing strip is between two tear lines, can cause distal portion by tearing tearing strip
Part quickly disintegrates in vivo so that described internal protective case and the load medicine apparatus for carrying realize sharp separation in vivo and
Withdraw from, therefore, the present invention can be used to carry protection when medicine apparatus is conveyed in vivo, to solve to carry easy when medicine apparatus is conveyed in vivo
The medicine of generation comes off, apparatus take off carry and to blood vessel wall the problems such as scratching damage, and present configuration is simple, operation side
