DETAILED DESCRIPTION

[0020] The present invention is described in detail below with reference to the accompanying drawings and embodiments:

[0021] Reference Figure 1-6 The utility model discloses a balloon catheter winding device, comprising: a frame 1, a bearing sleeve 11 is installed on the left shell plate of the frame 1, a rotating disk 2 is rotatably installed on the bearing sleeve 11, a rotating rod 21 is arranged on the frame 1, a driving device is installed on the right side of the rotating rod 21, the driving device drives the rotating disk 2 to rotate through a transmission structure, a catheter winding device is arranged on the left side of the rotating rod 21, the catheter winding device comprises a guide plate 22 installed on the left end of the rotating rod 21, a cross-shaped winding plate 23 is arranged at the left end of the guide plate 22, a clamping silicone block 24 is installed at each cross end of the winding plate 23, a catheter fixing hole 241 is opened on the clamping silicone block 24, the axis of the catheter fixing hole 241 is perpendicular to the extension part of the winding plate 23, a fixing device for fixing the catheter is arranged on the rotating disk 2, and a clamping device for clamping the balloon end of the balloon catheter is arranged at the output end of the driving device;

[0022] When spraying active substances on the balloon of the balloon catheter, the balloon end of the balloon catheter passes through the rotating disk 2 from the outside and extends to the output end of the driving device, the clamping device clamps the balloon end of the balloon catheter, and at the same time, the catheter extended from the other end is clamped and fixed on the clamping silicone block 24, the fixing device fixes the catheter, the catheter winding device winds the catheter, and the sprayer sprays the active substance on the area set on the balloon catheter. The driving device drives the balloon catheter to rotate, and at the same time, the driving device drives the rotating disk 2 to rotate through the transmission structure, driving the two sides of the balloon catheter to rotate synchronously, so that the spraying area at the balloon of the balloon catheter is circumferentially sprayed with active substances, so that a circular active substance layer is formed at the balloon.

[0023] The driving device is a driving motor 3 installed on the inner shell plate on the right side of the frame 1. The output end of the driving motor 3 is provided with a clamping device, which includes a catheter clamp 31 installed on the output end of the driving motor 3. The outer circle of the catheter clamp 31 is provided with an inclined thread, and a fixing nut 32 is rotatably installed on the outer shaft of the catheter clamp 31; when clamping the balloon end of the balloon catheter, the balloon end of the balloon catheter is inserted into the clamping part of the catheter clamp 31, and the fixing nut 32 is rotated, and the three claws of the catheter clamp 31 are automatically tightened to fix the balloon end of the balloon catheter.

[0024] The fixing device includes a protruding block extending from the right side of the rotating disk 2, a pressing block 25 is slidably mounted on the protruding block, and a fixing bolt 26 is rotatably mounted on the protruding block. The fixing bolt 26 presses the catheter of the balloon catheter into the gap of the rotating disk 2, thereby fixing the catheter of the balloon catheter;

[0025] After the balloon end of the balloon catheter is clamped, the catheter of the balloon catheter is placed into the gap on the protrusion of the rotating disk 2, and the fixing bolt 26 is rotated to press the pressing block 25 downward to tighten the catheter, thereby tightening the catheter.

[0026] After the catheter is tightened, the catheter is pressed into the catheter fixing hole 241 of the clamping silicone block 24 one by one according to the direction of rotation of the rotating disk 2 according to the section of the catheter extending out of the sprayer, thereby effectively preventing the tail of the catheter from swinging outside the sprayer and colliding with the nearby equipment or the outer edge of the sprayer when the balloon catheter is rotating to spray the active substance, and at the same time ensuring the cleanliness of the catheter on the balloon catheter.

[0027] The following is a first embodiment of the operation of the transmission structure:

[0028] The transmission structure includes a rotating gear 27 arranged on the rotating disk 2, a first motor 15 is installed on the inner side wall of the frame 1, and a first gear 151 is fixedly installed on the output end of the first motor 15. The first gear 151 is meshed and connected with the rotating gear 27, and the rotation speed of the first motor 15 is positively correlated with the rotation speed of the driving motor 3, so that the rotation speed of the rotating disk 2 driven by the first motor 15 is consistent with the speed and direction of the driving motor 3;

[0029] The driving motor 3 rotates to drive the catheter clamp 31 to rotate the balloon end of the balloon catheter. The first motor 15 drives the rotating gear 27 to rotate through the first gear 151, and the rotating gear 27 drives the rotating disk 2 to rotate synchronously, so that the two ends of the balloon catheter rotate synchronously to spray the active substance, avoiding the distortion of the balloon catheter due to inconsistent rotation of the two ends when the balloon catheter rotates, thereby affecting the quality of the active substance spraying.

[0030] In the actual processing process, the rotation speeds of the two motors are inconsistent, which causes the balloon catheter to be twisted during rotation, affecting the effect of spraying the active substance. To ensure that the rotation speeds of both ends of the balloon catheter are consistent, the transmission structure also includes a second embodiment:

[0031] The transmission structure includes a rotating gear 27 arranged on the rotating disk 2, a first transmission rod 12, a second transmission rod 13 and a third transmission rod 14 are rotatably installed inside the frame 1, a driving gear 33 is fixedly installed at the output end of the driving motor 3, and transmission gears are arranged at the ends of the first transmission rod 12, the second transmission rod 13 and the third transmission rod 14, and the transmission gear at one end of the first transmission rod 12 is meshed and connected with the driving gear 33, the transmission gear at the other end of the first transmission rod 12 is meshed and connected with the transmission gear at one end of the second transmission rod 13, the transmission gear at the other end of the second transmission rod 13 is meshed and connected with the transmission gear at one end of the third transmission rod 14, and the transmission gear at the other end of the third transmission rod 14 is meshed and connected with the rotating gear 27;

[0032] The driving motor 3 rotates to drive the catheter clamp 31 to rotate the balloon end of the balloon catheter. The driving motor 3 drives the first transmission rod 12 to rotate through the driving gear 33. The first transmission rod 12 drives the second transmission rod 13 to rotate through the transmission gear at the other end. The second transmission rod 13 drives the third transmission rod 14 to rotate through the transmission gear at the other end. The third transmission rod 14 drives the rotating gear 27 to rotate through the transmission gear at the other end, thereby driving the rotating disk 2 to rotate synchronously, thereby ensuring that the rotation speeds of the two ends of the balloon catheter are consistent, thereby avoiding the balloon catheter from twisting and entanglement due to inconsistent rotation speeds at both ends of the catheter when the active substance is sprayed, thereby affecting the production quality of the balloon catheter.
