Abstract

The invention relates to an implantable, adjustable and detachable ventricle training device. A small multi-section universal flexible structure is adopted; and a lining is segmented into a plurality of air bags for fine adjustment. In ventricle training operations, the root of a pulmonary artery is surrounded by the implantable, adjustable and detachable ventricle training device, and the air bags are inflated after the universal flexible structure is fixed, so that the aims of annularly contracting the pulmonary artery and training the left ventricle are fulfilled. In the perioperative period, the air quantity of the air bags is adjusted according to the condition, so that under the premise of completely training the ventricle, heart failure caused by excessive ring contraction is avoided, the risk of bedside thoracotomy is reduced, the postoperative mortality is reduced, and complete ventricle training preparation is made for the future operations. The connecting part of an air valve and a conduit adopts special design and adopts magnetic bayonet connection, so that the conduit can be taken out conveniently by a special guide wire without the thoracotomy, and the out-hospital life of patients is not influenced.

Description

A kind of embedded type scalable the ventricle training devices who removes

Technical field

The present invention uses less multi-section type Universal flexible structure, the multiple air bags for fine adjustment of liner segmentation are surrounded on pulmonary artery root by this invention, after multi-section type Universal flexible structure is fixed in the operation of ventricle training class, airbag aeration, reach ring contracting pulmonary artery, train the object of left chamber, can according to circumstances regulate gas flow in air bag at peri-operation period, can be in training up ventricle, avoid causing heart failure because excessively encircling contracting, reduce the other risk of opening breast of bed, minimizing postoperative death rate.And adjusting ring contracting degree, patient can conveniently extract outer body while leaving hospital, reduces the inconvenience of the outer life of Hospital of Patients.

At present, clinically for the uncontrollable banding belt of the left chamber general employing of training operation, interrupted suture, ring contracting gradually, in art, determine the degree of ring contracting according to blood oxygen saturation, also there is in the recent period external report distance type banding belt, but at present domestic is still blank in this regard, and there is following drawback in traditional ring contracting mode, one, owing to anaesthetizing in art, blood oxygen saturation is generally higher, objectively encircling contracting degree when operation technique can be more, postoperative along with tracheal intubation is extracted, vasoactive agent decrement, there is lung oligemia in most of patients, blood oxygen declines, left chamber overload, cause heart failure, often cause thus that breast is opened on bed side even dead, two, at present a lot of centers are for avoiding above-mentioned drawback, and the degree of art medium ring contracting is generally lighter, at this moment postoperatively may, because ring contracting amount is inadequate, not reach the object that train left chamber, three, once had distance type scalable banding belt abroad, but cost is high, the malfunctioning probability of remote control is high, carries the risk of blood vessel surrounding tissue while there is remote control ring contracting secretly simultaneously.Four, for simple gasbag-type banding belt, more because of aeration quantity, can push the aorta on side, cause operative failure.

In order to overcome the drawback of existing left chamber training technique, the present invention adopts two-layer composite, outer multi-section type Universal flexible structure, can be flexibly through the pulmonary artery that needs ring contracting, after keeping form fixing, can not be out of shape, the most basic ring contracting requirement ensureing, the multiple air bags in inner side, can encircle contracting pulmonary artery by inflation, be equipped with unidirectional blocking air valve at air bag root and inflating catheter connection bit, ensure air-tightness, and can press lower valve Rapid degassing by seal wire at perioperative, prevent early stage heart failure, reduce the other risk of opening breast of bed, reduce the generation of adverse events in institute.When patient leaves hospital, can import conduit by removing special seal wire, the magnetic bayonet socket of seal wire front end can pin with the corresponding magnetic bayonet socket of conduit and air valve junction, by the dismountable conduit of rotation seal wire.

Claims

1. the ventricle training devices that embedded type scalable is also removed, it is characterized in that, for the Universal flexible structure of the multiple sacculus of liner, this structure can be flexibly through the pulmonary artery of near-ring contracting, and fixing rear flexible arm will keep form and tension force, can not be out of shape, and multiple sacculus of liner can be according to gas flow adjustment ring contracting degree, and the independent air feed of each sacculus, ensures after indivedual sacculus breakages, whole device still can have ring contracting function.

2. device according to claim 1, postoperatively can adjust gas flow in sacculus according to conditions of patients, in the time of infant lung blood supply insufficiency, can be because of anoxia threat to life, now venting seal wire can be inserted to conduit, touch air valve, Non-return air valve can Rapid degassing, alleviate ring contracting degree, reduce the other risk of opening breast of postoperative bed; And in the time of lung hyperhematosis, increase gas flow in sacculus, and increase ring contracting dynamics, reach the object of training ventricle, for post-operative is prepared.

3. according to the device described in right 1,2, before leaving hospital, to remove special seal wire and insert conduit, the magnetic texure with draw-in groove of removing special seal wire front end will engage with the corresponding magnetic draw-in groove in air valve top, and rotation is removed seal wire and can be driven outer conduit together to back out, and extracts external.
