Description

Technical Field

[0001] The present invention relates to the technical field of medical catheter processing, and more specifically, to an automatic winding device for processing medical catheters. Background Art

[0002] Medical catheters are soft pipe equipment used to transport liquids, gases and other substances during medical diagnosis and treatment. They are widely used in different medical scenarios, such as surgery, diagnosis, interventional treatment, etc., to provide support, drainage, drug infusion and other functions. Currently, medical catheters need to be batch wound during production, packaging and storage management for packaging, transportation and storage management. However, the current batch winding method of medical catheters still has the following problems.

[0003] First of all, medical catheters are currently generally wound in a multi-layer batch winding manner using a single winding roller. The medical catheter is in direct rigid contact with the outer surface of the winding roller and is not limited accordingly, which causes the medical catheter to be easily stretched and deformed during the winding process, thereby affecting the catheter diameter. The change in diameter makes it easy for the internal liquid flow rate to be unstable when the catheter is used, or even for the pipeline to be blocked, which in turn affects its safety.

[0004] Secondly, in the multi-layer batch winding process, multiple layers of medical catheters are stacked layer by layer. Due to the pressure of the outer catheter on the inner catheter, a certain stress will be generated on the inner catheter. As the number of winding layers increases, the stress gradually accumulates, causing the inner catheter to be further squeezed and deformed under the pressure of the outer catheter, which may cause the inner catheter to be severely deformed locally and unusable, thereby affecting the product quality of the medical catheter. Summary of the invention

[0005] The invention provides an automatic winding device for processing medical catheters, which solves the technical problems that a multi-layer batch winding method with a single winding roller easily causes the medical catheter to be stretched and deformed, and that the stacking of multiple layers of medical catheters may squeeze the internal catheter.

[0006] The present invention provides an automatic winding device for processing medical catheters, comprising a machine body provided with a flexible winding roller, wherein the flexible winding roller comprises a supporting plate detachably mounted on the top of the machine body and a plurality of roller frames which are concentrically sleeved, wherein the innermost roller frame is detachably connected to the supporting plate, a flexible rubber roller sleeve for winding the catheter is fixedly sleeved on the outer side of the roller frame, a spiral receiving groove is provided on the outer side of the flexible rubber roller sleeve, a cylinder is fixedly mounted on the inner side of the innermost roller frame through a supporting plate, a plurality of positioning grooves are provided on the upper ends of the roller frames except the innermost roller frame, and a positioning mechanism is provided on the innermost roller frame.

[0007] The positioning mechanism includes positioning component 1, positioning component 2 and positioning component 3 which are fixedly installed on the inner side of the innermost roller frame and arranged in a circumference. Positioning component 1, positioning component 2 and positioning component 3 are arranged alternately up and down, and the heights of positioning component 1, positioning component 2 and positioning component 3 increase sequentially.

[0008] Furthermore, the positioning assembly 1 includes an articulated seat 1, which is fixedly mounted on the inner wall of the innermost roller frame, and a positioning rod 1 is hinged on the articulated seat 1.

[0009] Furthermore, the second positioning assembly includes a second articulated seat, on which a second positioning rod is articulated, and the second articulated seat is fixedly mounted on the inner wall of the innermost roller frame 202 .

[0010] Furthermore, the positioning component three includes an articulated seat three, which is fixedly installed on the inner wall of the innermost roller frame. A positioning rod three is hinged on the articulated seat three. The lengths of the positioning rod one, the positioning rod two and the positioning rod three increase successively. Torsion springs are arranged between the articulated seat one and the positioning rod one, between the articulated seat two and the positioning rod two, and between the articulated seat three and the positioning rod three.

[0011] Furthermore, a mounting sleeve is fixedly installed on the outer side of the cylinder output end, and push rods 1, 2 and 3 are respectively arranged between the positioning rods 1, 2 and 3 and the mounting sleeve, and push rods 1, 2 and 3 are fixedly connected to the outer side of the mounting sleeve through connecting rods, and the heights of push rods 1, 2 and 3 are reduced successively.

[0012] Furthermore, the push rod 1, the push rod 2 and the push rod 3 cooperate with the positioning rod 1, the positioning rod 2 and the positioning rod 3 respectively, and the push rod 1, the push rod 2 and the push rod 3 are fixedly installed with abutment rods on one side close to the innermost roller frame.

[0013] Furthermore, a driving motor is fixedly installed on the top of the machine body, an output end of the driving motor passes through the inner wall of the top of the machine body and is fixedly installed with a driving pulley, and a winding disk is rotatably installed on the top of the machine body.

[0014] Furthermore, the bottom of the winding disc passes through the inner wall of the top of the machine body and is fixedly sleeved with a driven pulley, and the driving pulley and the driven pulley are connected to each other by a same belt.

[0015] Furthermore, a Z-axis slide is fixedly installed on the top of the machine body, and a sliding seat is slidably connected to the front side of the Z-axis slide.

[0016] Furthermore, a plurality of tube-penetrating rings are fixedly mounted on the front side of the sliding seat, and the winding of the catheter is guided by the tube-penetrating rings.

[0017] The beneficial effects of the present invention are as follows: 1.

[0018] 2. Through the unidirectional push of the cylinder output end, the positioning rods 1, 2 and 3 can be driven in turn to press and position the corresponding roller frames to be replaced, thereby realizing the function of multiple positioning by a single drive, greatly saving the manufacturing and use costs of the equipment, and through the pressing and positioning of the roller frame, it can avoid the roller frame and the flexible rubber roller sleeve from loosening as a whole during the winding process, resulting in the inability to align the catheter with the flexible spiral and affecting the catheter winding quality, thereby greatly improving the efficiency and quality of the catheter winding.

[0029] See also Figure 1 and Figure 2 A driving motor 6 is fixedly installed on the top of the machine body 1. The output end of the driving motor 6 passes through the inner wall of the top of the machine body 1 and is fixedly installed with a driving pulley 8. A winding disk 7 is rotatably installed on the top of the machine body 1.

[0030] See also Figure 2 The bottom of the winding disk 7 passes through the top inner wall of the body 1 and is fixedly sleeved with a driven pulley 9. The driving pulley 8 and the driven pulley 9 are connected to each other with the same belt 10.

[0031] See also Figure 1 and Figure 2 A Z-axis slide 11 is fixedly installed on the top of the machine body 1, and a sliding seat 12 is slidably connected to the front side of the Z-axis slide 11.

[0032] See also Figure 1 and Figure 2 A plurality of tube-penetrating rings 13 are fixedly mounted on the front side of the sliding seat 12 , and the tube-penetrating rings 13 are used to guide the winding of the catheter.

[0033] During specific use, the support plate 201 is fixed on the top of the winding disk 7. At this time, only the innermost roller frame 202 is on the support plate 201. Then, the catheter to be wound is guided from right to left through several tube-threading rings 13 in turn, and then fixedly wound around the lower end of the spiral receiving groove. Then, the drive motor 6 is started, and the output shaft of the drive motor 6 rotates to drive the drive pulley 8 to rotate. The drive pulley 8 rotates and drives the driven pulley 9 to rotate through the belt 10, thereby driving the flexible winding roller 2 to rotate through the winding disk 7 to wind the catheter. At the same time, the Z-axis slide 11 drives the sliding seat 12 to rise slowly and uniformly, thereby driving the catheter to be wound along the spiral trajectory of the spiral receiving groove and embedded in the spiral receiving groove. Due to the flexibility of the flexible rubber roller sleeve 203 itself, the catheter will not be stretched or deformed during the winding process.

[0034] After the flexible rubber roller cover 203 on the innermost roller frame 202 is fully rolled up with the conduit, the conduit is cut off, and then a roller frame 202 with a diameter larger than that of the flexible rubber roller cover 203 is sleeved from top to bottom on the outside of the flexible rubber roller cover 203 with the conduit rolled up, and then the sleeved roller frame 202 is positioned by the positioning mechanism 3, and the winding operation is performed again after the positioning is completed. After the second winding is completed, the new roller frame 202 sleeved with the flexible rubber roller cover 203 and the winding operation are repeated until the overall winding operation is completed, and finally, the support plate 201 is released, and the support plate 201, multiple roller frames 202 and flexible rubber roller covers 203 are removed for packaging and storage. By setting up a spiral receiving groove for flexible spiral winding, the function of protecting the catheter from being stretched and deformed is achieved. At the same time, through the single-layer winding method of the spiral receiving groove, one spiral receiving groove only winds a single-layer catheter, thereby avoiding the problem of the catheter being squeezed and deformed due to stacking winding of multiple layers of catheters and affecting the quality. This greatly improves the stability of the catheter winding, ensures the quality of the catheter winding, and reduces the defective rate of the winding.

[0037] See also Figure 1 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The second positioning component 302 includes a second articulated seat 3021, which is fixedly mounted on the inner wall of the innermost roller frame 202, and a second positioning rod 3022 is hinged on the second articulated seat 3021.

[0038] See also Figure 1 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The positioning component three 303 includes an articulated seat three 3031, which is fixedly installed on the inner wall of the innermost roller frame 202. A positioning rod three 3032 is hinged on the articulated seat three 3031. The lengths of the positioning rod one 3012, the positioning rod two 3022 and the positioning rod three 3032 increase sequentially. Torsion springs are arranged between the articulated seat one 3011 and the positioning rod one 3012, between the articulated seat two 3021 and the positioning rod two 3022, and between the articulated seat three 3031 and the positioning rod three 3032.

[0039] See also Figure 1 , Figure 4 , Figure 5 , Figure 6 and Figure 7A mounting sleeve 4 is fixedly installed on the outer side of the output end of the cylinder 15, and a push rod 1 3013, a push rod 2 3023 and a push rod 3 3033 are respectively arranged between the positioning rod 1 3012, the positioning rod 2 3022 and the positioning rod 3 3032 and the mounting sleeve 4, and the push rod 1 3013, the push rod 2 3023 and the push rod 3 3033 are fixedly connected to the outer side of the mounting sleeve 4 through a connecting rod, and the heights of the push rod 1 3013, the push rod 2 3023 and the push rod 3 3033 are successively reduced, and the push rod 1 3013, the push rod 2 3023 and the push rod 3 3033 are respectively matched with the positioning rod 1 3012, the positioning rod 2 3022 and the positioning rod 3 3032, and the push rod 1 3013, the push rod 2 3023 and the push rod 3 3033 are fixedly installed with a contact rod 304 on one side close to the inner wall of the innermost roller frame 202.

[0040] When in use, after the flexible rubber roller sleeve 203 on the innermost roller frame 202 is fully rolled up with the conduit and a roller frame 202 having a diameter larger than that of the flexible rubber roller sleeve 203 is replaced, the mounting sleeve 4 is pushed upward by the cylinder 15, thereby driving the push rod 1 3013, the push rod 2 3023 and the push rod 3 3033 to move upwards through the connecting rod. During the movement, the push rod 1 3013 first contacts the positioning rod 1 3012 and pushes the positioning rod 1 3012 upwards, and the positioning rod 1 3012 is moved upwards. Rod 3012 rotates in the direction away from pushing rod 3013 with its hinge with hinge seat 3011 as the center, and then presses into the positioning groove 5 on the replaced roller frame 202, and as pushing rod 3013 continues to move upward, pushing rod 3013 drives the corresponding abutting rod 304 to abut against positioning rod 3012, thereby fixing the positioning rod 3012, and then pressing and fixing the roller frame 202. At this time, the output end of cylinder 15 stops, and then the winding operation continues.

[0041] After the winding is completed, the operation of replacing the large diameter roller frame 202 is repeated, and the installation sleeve 4 is pushed to move upward through the output end of the cylinder 15, and then the push rod 3023 will contact the positioning rod 3022 and push the positioning rod 3022 upward, and the positioning rod 3022 rotates in the direction away from the push rod 3023 with its hinged position with the hinged seat 3021 as the center, and then presses into the positioning groove 5 on the corresponding roller frame 202, and as the push rod 3023 continues to move, the push rod 3023 drives the corresponding abutment rod 304 to abut against the positioning rod 3022 3022, thereby achieving the fixation of the positioning rod 2 3022, and then achieving the compression and fixation of the roller frame 202. During this process, the pushing rod 1 3013 will drive the abutment rod 304 fixedly connected to it to move upward and maintain a sliding abutment state with the positioning rod 1 3012. Then, the operation of replacing the large diameter roller frame 202 is repeated and the pushing rod 3 3033 is driven by the output end of the cylinder 15 to make the positioning rod 3 3032 rotate, and the positioning rod 3 3032 is fixed to the corresponding roller frame 202 through the corresponding abutment rod 304, and then the winding operation is continued.

[0042] When it is necessary to disassemble the multiple concentrically arranged roller frames 202, the output end of the cylinder 15 contracts to drive the installation sleeve 4 to move downward, thereby driving the push rod 1 3013, the push rod 2 3023 and the push rod 3 3033 to move downward through the connecting rod, and successively disengage from the fixation of the positioning rod 1 3012, the positioning rod 2 3022 and the positioning rod 3 3032, and then the positioning rod 1 3012, the positioning rod 2 3022 and the positioning rod 3 3032 are reset under the action of the torsion spring, thereby releasing the compression and positioning of the multiple roller frames 202, and then the multiple concentrically arranged roller frames 202 can be disassembled, and the fixation of the support plate 201 and the innermost roller frame 202 can be released.

[0043] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
