In existing technology, the common practice is to place the tubing coil on a transfer carrier, and then use a transfer carrier to transport the wound tubing to the feeding position of the packaging machine. Finally, the wound tubing on the transfer carrier is fed into the blister, thus completing the functions of tubing winding and feeding.

[0003] However, existing packaging methods are prone to problems such as loosening of the tubing during wrapping, transportation, and blister packing; and problems such as the tubing being squeezed against the blister wall due to insecure fixing, resulting in tubing damage or exposure of the blister pack.

Figure 1 , Figure 2 and Figure 4 The winding device includes a winding structure 1, a vein needle positioning structure 2, a translation structure 4, a lifting structure 5, and a vein needle assembly transfer mechanism 6. The translation structure 4 is connected to the winding structure 1 via the lifting structure 5 to drive the winding structure 1 to move between the blister 7 and the vein needle positioning structure 2. When the winding structure 1 begins to wind the vein needle assembly, the winding structure 1 and the vein needle positioning structure 2 are respectively positioned on both sides of the vein needle assembly transfer mechanism 6. The vein needle positioning structure 2 is used to position the vein needle end of the vein needle assembly transferred by the vein needle assembly transfer mechanism 6. The winding structure 1 includes a fixing component 12, a linkage component 13, and a rotating component 14. The fixing component 12 includes an adsorption element 12421 and a spring clip 124. 4. A plurality of lifting guide rods 1243; a rotating assembly 14 is connected to a fixed assembly 12 and a linkage assembly 13 respectively, and the rotating assembly 14 is used to drive the fixed assembly 12 to rotate so that the catheter of the intravenous needle assembly is wound around the plurality of lifting guide rods 1243, and the plurality of lifting guide rods 1243 are used to insert into the blister 7 and move relative to the catheter so that the catheter is fixed in the groove of the blister 7; the linkage assembly 13 includes a transmission member 134, the transmission member 134 is connected to a spring clip 1244, and the transmission member 134 is used to drive the spring clip 1244 to open or close by lifting so that the spring clip 1244 clamps the accessory end of the intravenous needle assembly; an adsorption member 12421 is used to adsorb the intravenous needle end of the intravenous needle assembly.

[0030] This utility model embodiment at least alleviates the technical problem in the prior art where, during the packaging of medical needle instruments, the catheter is not securely fixed, resulting in catheter damage or exposure of the blister pack.

[0031] In this embodiment of the utility model, there are two sets of translation structures 4, which are spaced apart and arranged in the same direction. A frame is erected between the two sets of translation structures 4, and a lifting structure 5 is provided on the frame along the vertical line. The output end of the lifting structure 5 is provided with a winding structure 1. The lifting structure 5 and the translation structure 4 can both be powered by a cylinder and move the connecting structure on the track. Multiple winding structures 1 can be provided, and each winding structure 1 is connected to the output end of the lifting structure 5. Preferably, the multiple winding structures 1 are arranged side-by-side in the same direction. Correspondingly, the number of catheters connected to the vein needle positioning structure 2 and the vein needle assembly transfer mechanism 6 is the same as the number of winding structures 1. Specifically, the vein needle positioning structure 2 is connected to the vein needle end of the vein needle assembly; and the vein needle assembly transfer mechanism 6 is connected to the accessory end of the vein needle assembly, so as to straighten the catheter of the vein needle assembly through the vein needle positioning structure 2 and the vein needle assembly transfer mechanism 6. Each winding structure 1 includes an adsorption element 12421, a spring clip 1244, and multiple lifting guide rods 1243. In use, the accessory end is clamped by the spring clip 1244. The winding structure 1 rotates to make the catheter wrap around multiple lifting guide rods 1243. The multiple lifting guide rods 1243 are spaced apart and form a polygon. The catheter passes around the multiple lifting guide rods 1243 in sequence to make the catheter wound into a polygon. When the winding structure 1 moves to the intravenous needle positioning structure 2, the intravenous needle tip can be attracted and fixed by the suction member 12421, thereby realizing the simultaneous fixation of the intravenous needle tip, catheter and accessory end. Then the winding structure 1 is moved to the blister 7. By inserting the lifting guide rods 1243 into the groove of the blister 7, the catheter is placed into the groove of the blister 7. Then, by separating the lifting guide rods 1243 from the catheter and separating the intravenous needle tip and accessory end simultaneously, the catheter can be completely placed in the blister 7.

[0032] Compared with the prior art, this utility model embodiment provides a winding device, which uses a winding structure 1 to simultaneously fix the catheter and its two ends, the venous needle end and the accessory end. Specifically, the venous needle end can be fixed by the adsorption member 12421, the accessory end can be fixed by the spring clip 1244, and the catheter can be fixed by the lifting guide rod 1243. This allows the catheter, its venous needle end and the accessory end to be placed simultaneously in the groove of the blister 7, thereby effectively avoiding the situation where the catheter is not securely fixed after being placed in the blister 7, and avoiding the risk of catheter damage.

[0033] In an optional implementation of this embodiment, refer to Figure 3 The winding structure 1 also includes a connecting component 11, which is connected to the lifting structure 5 and is connected to the fixing component 12 and the rotating component 14 respectively.

[0034] Specifically, the connecting assembly 11 includes a connecting frame 111, a connecting vertical plate 112, a connecting horizontal plate 113, and a connecting plate 114. The connecting frame 111 has an L-shaped bent structure, and its top horizontal portion is detachably connected to the frame at the output end of the lifting structure 5 by bolts. The vertical portion of the connecting frame 111 is connected to the vertically distributed connecting vertical plates 112 by bolts. One side of the bottom of the connecting vertical plate 112 is connected to the connecting horizontal plate 113 in the horizontal direction, and the bottom side of the connecting vertical plate 112 facing away from the connecting horizontal plate 113 is connected to the connecting plate 114. This forms an overall structure for connection with the fixed assembly 12 and the rotating assembly 14.

[0035] Furthermore, referring to Figure 3 The fixing component 12 includes a first driving member 121, a connecting frame 122, a lifting rod 123, and a fixing mechanism 124. The first driving member 121 is connected to the connecting component 11, and the first driving member 121 is connected to the lifting rod 123 through the connecting frame 122. The end of the lifting rod 123 away from the connecting frame 122 is connected to the fixing mechanism 124. The fixing mechanism 124 is connected to the rotating component 14, and the rotating component 14 drives the fixing mechanism 124 to rotate.

[0036] Specifically: the first driving component 121 can be connected to the side of the connecting vertical plate 112 opposite to the connecting horizontal plate 113, and the first driving component 121 is distributed in the vertical direction. The output end of the bottom of the first driving component 121 is connected to one end of the connecting frame 122. The other end of the connecting frame 122 passes through the connecting vertical plate 112 in the horizontal direction and is connected to the lifting rod 123. The bottom of the lifting rod 123 is connected to the fixing mechanism 124, so that the first driving component 121 drives the fixing mechanism 124 to move in the vertical direction through the connecting frame 122 and the lifting rod 123.

[0037] Furthermore, referring to Figure 5 The fixing mechanism 124 includes a first lifting plate 1241 and a second lifting plate 1242. The first lifting plate 1241 is connected to the lifting rod 123 and is provided with a spring clip 1244. The second lifting plate 1242 is connected to the first lifting plate 1241 through a connecting rod and is connected to the adsorption member 12421. A plurality of lifting guide rods 1243 are distributed at intervals, and the end of the lifting guide rod 1243 facing away from the first lifting plate 1241 is used to wind the conduit.

[0038] Specifically: The top of the first lifting plate 1241 is connected to the lifting rod 123, and the edge of the first lifting plate 1241 is provided with multiple lifting guide rods 1243 along the vertical direction. There can be four lifting guide rods 1243, and all of them are connected to the second lifting plate 1242, so as to realize the synchronous lifting and lowering movement of the second lifting plate 1242 through the first lifting plate 1241 via two connecting rods; the bottom of the lifting guide rods 1243 extends through the rotating assembly 14 to form a winding frame structure through the multiple lifting guide rods 1243. In use, the conduit is connected by winding it around the multiple lifting guide rods 1243; when the number of lifting guide rods 1243 is four and the endpoints are distributed in a matrix, the conduit wound around the four lifting guide rods 1243 forms a rectangular shape to match the groove of the blister 7.

[0039] Furthermore, referring to Figure 3 and Figure 4 The linkage assembly 13 also includes a second drive member 131, a moving block 132 and a linkage rod 133. The second drive member 131 is connected to the connecting frame 122 and the second drive member 131 is connected to the linkage rod 133 through the moving block 132. The linkage rod 133 passes through the lifting rod 123 and is connected to the transmission member 134.

[0040] Specifically: the second driving component 131 is connected to the connecting frame 122, and the output end of the second driving component 131 is connected to a moving block 132 in the vertical direction. The moving block 132 can be a slider, and the corresponding connecting frame 122 is provided with a vertically arranged slide rail so that the moving block 132 is slidably connected to the slide rail, thereby realizing the stable movement of the moving block 132. The moving block 132 is connected to a connecting rod 133, which is distributed in the vertical direction and connects to the transmission component 134 after passing through the lifting rod 123, so that the second driving component 131 drives the transmission component 134 to move in the vertical direction through the moving block 132 and the connecting rod 133.

[0041] Furthermore, referring to Figure 6 The transmission component 134 has a through hole with a top diameter smaller than the bottom diameter. The through hole is fitted onto the first end of the spring clip 1244. The wall of the through hole is used to press the first end of the spring clip 1244 when the transmission component 134 moves down, so that the second end of the spring clip 1244 opens.

[0042] Specifically: the top of the spring clip 1244 is the first end, and its bottom is the second end; the spring clip 1244 is rotatably connected to the extension frame of the first lifting plate 1241 via a rotating shaft, and a spring is connected between the first ends of the spring clip 1244. The tension of the spring keeps the first end of the spring clip 1244 in an open state, so the second end of the spring clip 1244 is in a closed state. Preferably, the first end of the spring clip 1244 is provided with a roller. In use, by fitting the through hole of the transmission member 134 onto the first end of the spring clip 1244, the transmission member 134 applies a force to bring the two rollers closer together during the downward pressing process, thereby causing the first end of the spring clip 1244 to gradually close, and the second end of the spring clip 1244 to open, so that the spring clip 1244 can clamp the accessory end through the second end. Then the transmission member 134 moves upward, the spring opens again, and at this time the second end of the spring clip 1244 can clamp the accessory end.

[0043] Correspondingly, the top diameter of the through hole can be set to be larger than the bottom diameter. In use, by fitting the through hole of the transmission member 134 onto the first end of the spring clip 1244, the transmission member 134 applies a force to bring the two rollers closer together during the upward movement, thereby causing the first end of the spring clip 1244 to gradually close and the second end of the spring clip 1244 to open, so that the spring clip 1244 can clamp the accessory end through the second end. Then the transmission member 134 moves down and the spring opens again, at which time the second end of the spring clip 1244 can clamp the accessory end.

[0044] In an optional implementation of this embodiment, refer to Figure 3 The rotating assembly 14 includes a rotating motor 141, a transmission assembly 142, and a rotating mechanism 143. The rotating motor 141 is connected to the connecting assembly 11, and the rotating motor 141 is connected to the rotating mechanism 143 through the transmission assembly 142. The rotating mechanism 143 has a receiving space, and the receiving space has a fixing mechanism 124 and a transmission component 134.

[0045] Specifically: the rotating motor 141 is connected to the bottom of the connecting plate 114 by bolts, and the output end of the rotating motor 141 is connected to the transmission assembly 142 after passing through the connecting plate 114. The transmission assembly 142 includes a first pulley and a belt connected to the rotating motor 141, and a second pulley connected to the rotating mechanism 143. The rotating motor 141 can drive the rotating mechanism 143 to rotate through the transmission assembly 142.

[0046] Furthermore, referring to Figure 5 and Figure 6The rotating mechanism 143 includes a top plate 1431, a bottom plate 1432, a guide column 1433, and an outer cover 1434. The top plate 1431 is connected to the transmission assembly 142, and the outer cover 1434 is provided between the top plate 1431 and the bottom plate 1432. One end of the guide column 1433 is connected to the top plate 1431, and the other end is connected to the bottom plate 1432.

[0047] Specifically: the second pulley can be connected to the connecting horizontal plate 113 via a flange, and the top of the top plate 1431 is connected to the bottom plate 1432 via an outer cover 1434, forming a closed accommodating space between the top plate 1431, the outer cover 1434, and the bottom plate 1432. It should be noted that there are two guide columns 1433, with their bottoms connected to the bottom plate 1432 and their tops connected to the top plate 1431. Without affecting the lifting and lowering of the transmission component 134, the first lifting plate 1241, and the second lifting plate 1242, the guide columns 1433 can drive the transmission component 134, the first lifting plate 1241, and the second lifting plate 1242 to rotate.

[0048] It should be noted that the adsorption component 12421 includes an air pump, a pipeline, and a suction cup.

The reset moving component 23 includes a sliding component and a slide rail. The sliding component is connected to the positioning groove 24 so that the positioning groove 24 can be moved by sliding the sliding component. The positioning connecting rod 25 is mounted above the multiple positioning grooves 24 and is connected to a cylinder on one side. The cylinder drives the positioning connecting rod 25 to move. The positioning connecting rod 25 is provided with multiple positioning components 251, which are matched with the corresponding positioning grooves 24. The end of the positioning component 251 is provided with a barb so that after the positioning component 251 is pressed on the corresponding intravenous needle tip, the positioning component 251 hooks the intravenous needle tip to prevent the intravenous needle tip from coming out of the positioning groove 24 during the winding process.

[0051] Furthermore, referring to Figure 1 The intravenous needle assembly transfer mechanism 6 includes a horizontal moving mechanism and an intravenous needle assembly carrier. The intravenous needle assembly carrier is connected to the horizontal moving mechanism and is used to place the intravenous needle assembly. The horizontal moving mechanism is used to move the intravenous needle assembly carrier from one side to between the winding structure 1 and the intravenous needle positioning structure 2.

[0052] Specifically: The horizontal movement mechanism of the intravenous needle assembly transfer mechanism 6 includes a cylinder and a track to drive the intravenous needle assembly carrier connected to the track, along with the intravenous needle assembly, to move along the track; it should be noted that the intravenous needle assembly transfer mechanism 6 can achieve lifting and lowering transfer, while the corresponding intravenous needle positioning structure 2 does not need to be lifted and lowered; however, when the intravenous needle assembly transfer mechanism 6 can only move horizontally and cannot be lifted and lowered, the corresponding intravenous needle positioning structure 2 needs to be lifted and lowered in coordination.

[0053] In an optional implementation of this embodiment, refer to Figure 1 The winding device also includes a frame 3, which is connected to the translation structure 4 and the lifting structure 5 respectively.

[0054] Specifically: the frame 3 can be a cuboid frame structure, which is connected to the translation structure 4 and the lifting structure 5 respectively, and the translation structure 4 and the lifting structure 5 are erected at a certain height so that the multiple winding structures 1 connected to the lifting structure 5 can be located above the vein needle positioning structure 2 and the vein needle assembly transfer mechanism 6.

[0055] It should be noted that the first drive component 121, the second drive component 131, the third drive component 21, and the fourth drive component 252 can all be cylinders or electric cylinders, etc.

[0056] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments.
