Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a balloon forming machine. Background Art

[0002] The balloon is an interventional treatment device. The efficacy and safety of drug-eluting balloons in various coronary artery stenosis, small vessel lesions, bifurcation lesions, etc. have been confirmed by multiple clinical trials. According to the treatment site, drug-eluting balloons can be divided into coronary drug-eluting balloons, peripheral drug-eluting balloons, etc. The balloon forming machine is used to manufacture medical balloons. For the processing of balloons on catheters, it is necessary to first stretch them thin and then shape them during inflation. Often, the tube embryo is first stretched thin, and then inflated into the tube embryo, and the balloon is shaped by the mold to complete the balloon molding on the tube embryo.

[0003] The current method used for balloon molding is integrated balloon molding, in which the two ends of the tube embryo are respectively fixed on the inflation mechanism and the clamping mechanism. The inflation mechanism and the clamping mechanism are stretched outward with the molding mechanism as the center, and the stretched tube embryo is shaped into a balloon through the molding mechanism, thereby completing the one-piece molding of the balloon.

[0004] Although the above-mentioned balloon forming method can improve the balloon production efficiency through automatic integration, during the expansion process of the tube embryo, the section to be expanded of the tube embryo will change with the process of stretch blow molding, resulting in uneven thickness of the balloon wall and uneven balloon performance, which affects the consistency of the balloon.

[0035] During operation, the movable mold 221 and the fixed mold 222 overlap, and the tube embryo is placed in the mold. The oil temperature control system is regulated to increase the temperature of the movable seat 212 and the fixed seat 213, and the temperature of the tube embryo is controlled by heat conduction. By adjusting the first slide seat 3111 and the lifting cylinder 321, the center point of the tube embryo fixing hole 324 and the central axis of the tube embryo are set on the same straight line. By adjusting the second slide seat 3121, the fixing plate 323 is moved toward the tube embryo, and the clamping cylinder 322 controls the opening and closing of the fixing plate 323, so that the tube embryo fixing hole 324 clamps the tube embryo. The output end 3321 of the cylinder 332 provides thrust to the inflator 331, so that the inflator 331 moves toward the tube embryo, so that the gas outlet 3313 is inserted at one end of the tube embryo. The air inlet 3312 of one of the inflators 331 is sealed to form a sealing structure with the tube embryo. High-pressure gas is introduced into the other air inlet 3312. The gas enters the tube embryo through the inflator 331. The tube embryo is easily deformed by heat and expands when encountering high-pressure gas, and adheres to the inner wall of the balloon mold 22 to form the desired balloon. The oil temperature control system is adjusted to cool and solidify the balloon. After the balloon is cooled and formed, the output part of the second lifting cylinder 41 is lifted, and the conveying rack 42 is lifted accordingly, so that the height of the conveying rack 42 is higher than the height of the fixed seat 213. The balloon rolls along the conveying rack 42 to the storage frame 43 and is stored in the storage frame 43. Since a plurality of the forming devices 20 are arranged on the base 10, the third slide rail 3131 is adjusted to move the fixed inflating device 30 to both sides of another forming device 10 to make a new balloon.

[0036] Compared with the prior art, the balloon forming machine provided by the utility model realizes the formation of the balloon by setting the forming device 10 and the solid inflation device 20.
