Description
Technical Field
The utility model belongs to medical equipment especially relates to a be used for accurate quantitative injection pipe of two sacculus.
Background
In the current ISR treatment scheme, the risk factors and contraindications of coronary artery bypass grafting are more, the risk of repeated ISR and other repeated stent implantation can be caused by the re-implantation of the stent, foreign body plants are avoided by the drug eluting balloon (DCB) treatment, and the necessary subsequent treatment opportunity is reserved for patients. The medicine sacculus of using on the market at present, can release the medicine to local vascular wall, reduce time and intensity of antiplatelet treatment, and avoid the internal foreign matter that puts into, be used for treating ISR, secondly in small vessel pathological change, branching pathological change, the patient that has high bleeding risk, the patient that is taking oral anticoagulant medicine or recently carries out surgery, the patient that has had thrombus history in the subacute support, refuse the patient of internal implanted foreign matter, sacculus surface scribbles fixed medicine, but the medicine of coating adopts the medicine of anti smooth muscle cell proliferation such as taxol or rapamycin mostly, through realizing local treatment plaque, prevent and treat ISR, occupy the important position in coronary heart disease interventional therapy field, nevertheless, medicine coating sacculus still has some problems: 1. the types of medicine coating balloons on the market are limited; 2. uniform and accurate administration cannot be realized; 3. repeated administration is not possible; 4. the cost is expensive. In response to the above drawbacks, we have shifted the focus to the drug-filled balloon. The drug injection balloon is only used for animal experiments at present, (1) clear way is extremely low in yield, limited in variety, incapable of being transformed into clinical application and incapable of accurately controlling the drug injection amount; (2) the middle section perfusion saccule with the blocking saccule at the two ends can only inject the medicine into the vascular cavity and has no effect on the vascular wall.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome above-mentioned prior art's shortcoming, provide a simple structure reasonable, the even mastoid process in sacculus surface is wherein with the medicine injection in the vascular wall inner membrance of abrupt income under the high-pressure effect, and the blood vessel of same patient's multiple pathological changes can use repeatedly and annotate the medicine, and accurate control dosage conveniently changes the injection kind, can reduce use cost to can alleviate the economic burden of patient and family members.
The utility model discloses a realize through following technical scheme:
a double-balloon precise quantitative medicine injection catheter comprises a guide wire, a main catheter and a balloon, wherein the balloon consists of an inner balloon and an outer balloon, the outer balloon is wrapped outside the inner balloon, the main catheter is arranged in the middle of the outer balloon and the inner balloon, the guide wire is arranged in the main catheter, the guide wire penetrates through a guide wire inlet arranged on the main catheter and penetrates out of a guide wire outlet, a pressurizing catheter and a medicine injection catheter are arranged in the main catheter, the outlet end of the medicine injection catheter penetrates through the catheter and is arranged in a gap between the inner balloon and the outer balloon, the other end of the medicine injection catheter is connected with a medicine injection pump, and a control valve is arranged on the medicine injection catheter; the outlet end of the pressurizing catheter passes through the main catheter and is communicated with the inner balloon, and the other end of the pressurizing catheter is connected with a pressurizing pump; the outer wall of the outer balloon is provided with a plurality of mastoids, and the mastoids are provided with medicine outlets.
The outlet end of the pressurizing conduit is provided with at least one outlet communicated with the inner balloon.
The utility model has the advantages that: the utility model discloses an accurate quantitative injection pipe of two sacculus can realize the accurate control to using the medicine dosage, and the medicine pours into the intraductal membrane of blood into, and doses evenly, and extravagant medicine makes medicine can the full play effect. The medicine can be injected repeatedly, and the kinds of the injected medicine can be changed. The medicine injection quantity and the pressurization size are respectively controlled by the medicine injection pipe and the pressurization pipe, the medicine in the medicine bag is discharged from the mastoid on the outer ball bag under the pressure of the inner ball bag, and the medicine is fully contacted with the blood vessel, so that a better treatment effect is achieved.
