[0032] Please refer to Figure 1 and Figure 5, this embodiment provides an infusion set catheter placement position correction device 100, which includes a catheter straightening mechanism 110 and a catheter placement mechanism 120; the catheter straightening mechanism 110 includes a support plate 111, and the support plate 111 can move vertically to approach or move away from the catheter 200; the catheter placement mechanism 120 includes a clamping assembly 121 and a limiting assembly 122 arranged at intervals, and the clamping assembly 121 is used for clamping the catheter 200; the limiting assembly 122 has a plurality of partition slots 1224 arranged side by side; the carrier 210 clamps the middle section of the catheter 200; the support plate 111 moves vertically to support the tail section of the catheter 200, and moves horizontally to straighten the catheter 200; after the catheter 200 is straightened, the limiting assembly 122 can separate the tail sections of multiple catheters 200 one by one through the partition slots 1224; the clamping assembly 121 can clamp the tail section of the catheter 200 and move horizontally to place the catheter 200 on the carrier 210.
[0033] When the carrier 210 clamps the catheter 200 and moves from the previous station to the next station, passing through the infusion set catheter placement position correction device 100 provided by the present application, the placement position of the catheter 200 can be corrected so that it can meet the placement requirements of the subsequent station when being transferred by the carrier 210 to the subsequent station.
[0034] Specifically, the infusion set catheter placement position correction device 100 includes a catheter straightening mechanism 110 and a catheter placement mechanism 120. The catheter straightening mechanism 110 can flatten and straighten the tail end of the catheter 200 processed in the previous station, and the catheter placement mechanism 120 can separate the tail ends of multiple catheters 200, and clamp the catheter 200 onto the carrier 210, so that the carrier 210 moves the catheter 200 with corrected position to the subsequent station for processing.
[0035] Among them, the catheter straightening mechanism 110 includes a support plate 111. When the carrier 210 clamps the catheter 200 and passes through the infusion set catheter placement position correction device 100 provided by the present application, there is a situation where the middle section of the catheter 200 is clamped by the carrier 210, resulting in the tail section of the catheter 200 being in a hanging state without support force; at this time, the support plate 111 can move vertically to support the tail section of the catheter 200 and move horizontally to ensure that the middle section and the tail section of the catheter 200 are on the same horizontal plane, and the tail section of the catheter 200 is straightened by the frictional force during the relative movement with the support plate 111;
[0036] Preferably, in order to prevent the catheter 200 from slipping when the support plate 111 supports and straightens the catheter 200, as Figure 4As shown, on the side of the support piece 111 facing the catheter 200, there are a plurality of V-shaped grooves for clamping the catheter 200. The plurality of V-shaped grooves 1111 are arranged side by side in sequence to ensure that each catheter 200 can be correspondingly clamped in a V-shaped groove, and the plurality of catheters 200 can be separated one by one, making the process of the subsequent limiting component 122 of the catheter placement mechanism 120 separating the tail sections of the plurality of catheters 200 more efficient and convenient.
[0037] The catheter placement mechanism 120 includes a clamping component 121 and a limiting component 122. The limiting component 122 has a plurality of separating grooves 1224 arranged side by side. After the tail section of the catheter 200 is straightened by the support piece 111, the limiting component 122 can move towards the catheter 200, so that the tail sections of the plurality of catheters 200 are separated one by one by the separating grooves 1224 of the limiting component 122. Such a setting can further ensure the orderliness of the placement position of the catheter 200; the clamping component 121 can clamp the tail section of the catheter 200 and move horizontally to readjust the position of the catheter 200 arranged on the carrier 210, facilitating the carrier 210 to clamp the catheter 200 and enter the next working station.
[0038] The above-mentioned infusion catheter placement position correction device 100 can flexibly correct the placement position of the infusion catheter 200 to ensure that when the infusion device enters the subsequent working station from the previous working station, the placement position of its catheter 200 meets the requirements of the subsequent working station, realizing the orderly connection between the front and subsequent working stations.
[0039] In an implementable manner of the present application, as Figure 4 shown, the catheter straightening mechanism 110 further includes a guide plate 112. The guide plate 112 is arranged parallel to the support piece 111, and the support piece 111 can move vertically along the plate surface of the guide plate 112; when the catheter 200 is conveyed to the infusion catheter placement position correction device 100, the side edge of the guide plate 112 can support the tail section of the catheter 200 to make the catheter 200 horizontal; the support piece 111 moves vertically along the plate surface of the guide plate 112 to support the catheter 200, and moves horizontally with the guide plate 112 to straighten the catheter 200 through the relative friction between the support piece 111 and the catheter 200.
[0040] Specifically, as Figure 4As shown, the tube-pushing mechanism 110 also includes a guide plate 112, the plate surface of the guide plate 112 is parallel to the movement plane of the support piece 111, and the plate surface height of the guide plate 112 is greater than the height of the support piece 111. Therefore, when the carrier 210 clamps the catheter 200 and passes through the infusion set catheter placement position correction device 100 provided in the present application, the carrier 210 clamps the middle section of the catheter 200. At this time, the tail section of the catheter 200 can be supported by the side edge of the guide plate 112, so that the subsequent process of the support piece 111 moving in the vertical direction and supporting the catheter 200 is more reliable, so that the support piece 111 can quickly clamp the catheter 200 in the V-shaped groove, thereby improving the efficiency of the correction process of the infusion set catheter placement position correction device 100.
[0041] For example, please refer to Figure 3 and Figure 5 The limiting assembly 122 includes a first movable cylinder 1221 and a limiting clamp 1222. The first movable cylinder 1221 includes a first movable sliding portion, and the limiting clamp 1222 is fixedly arranged with the first sliding portion. The first movable cylinder 1221 can drive the limiting clamp 1222 to reciprocate in the vertical direction through the first sliding portion to approach or move away from the catheter 200; the limiting clamp 1222 can be arranged around the outer wall of the catheter 200 to limit the tail section of the catheter 200.
[0042] Specifically, Figure 3 and Figure 5 As shown, the limiting assembly 122 includes a first movable cylinder 1221 and a limiting clamp 1222. The limiting clamp 1222 is driven by the first movable cylinder 1221 to approach or move away from the catheter 200. The limiting clamp 1222 can be arranged around the outer wall of the catheter 200 to limit the tail section of the catheter 200; preferably, the limiting assembly 122 includes a plurality of limiting clamps 1222, and the plurality of limiting clamps 1222 are arranged in parallel along the arrangement direction of the plurality of catheters 200. The plurality of limiting clamps 1222 correspond to the plurality of catheters 200 one by one, so that the limiting assembly 122 can limit the plurality of catheters 200 at the same time, so as to ensure that the shape of the tail section of the catheter 200 is controlled in the process of the subsequent clamping assembly 121 moving the catheter 200 to the carrier 210, thereby improving the reliability and efficiency of the correction of the placement position of the catheter 200.
[0043] Alternatively, if Figure 5 As shown, the limiting assembly 122 also includes a pressing block 1223, which is fixedly connected to the first sliding portion of the first movable cylinder 1221 and is located on the side of the limiting clamp 1222 away from the clamping assembly 121; the separating groove 1224 is arranged on the side of the pressing block 1223 away from the first movable cylinder 1221; the limiting assembly 122 has a plurality of limiting clamps 1222, and the separating grooves 1224 correspond one-to-one to the limiting clamps 1222; the tail sections of the plurality of catheters 200 are respectively limited one by one by the limiting clamps 1222, and are sequentially passed through the separating grooves 1224.
[0044] Specifically, as Figure 5 shown, the limiting component 122 further includes a pressing block 1223. The pressing block 1223 can be driven by the first movable cylinder 1221 to approach or move away from the conduit 200. A plurality of separation grooves 1224 are arranged side by side on the side of the pressing block 1223 facing away from the first movable cylinder 1221. The number and arrangement positions of the plurality of separation grooves 1224 correspond one by one to the number and arrangement positions of the plurality of limiting clips 1222. When the first movable cylinder 1221 drives the pressing block 1223 and the limiting clips 1222 to move towards the tail section of the conduit 200, the pressing block 1223 can first separate the plurality of conduits 200 one by one through the plurality of separation grooves 1224. At this time, the first movable cylinder 1221 continues to drive the pressing block 1223 and the limiting clips 1222 to move towards the tail section of the conduit 200 until the limiting clips 1222 can be looped around the outer wall of the conduit 200 to control the state of the tail section of the conduit 200 during the subsequent transfer of the conduit 200 by the clamping component 121. Through the cooperation of the limiting clips 1222 and the pressing block 1223, the separation and limiting processes of the plurality of conduits 200 are made more orderly and efficient.
[0045] Exemplarily, as Figure 3 and Figure 5 shown, the clamping component 121 includes a second movable cylinder 1211 and a clamping member 1212. The clamping member 1212 is used to clamp the conduit 200. The second movable cylinder 1211 includes a second sliding part arranged movably. The clamping member 1212 is fixedly arranged with the second sliding part. The second movable cylinder 1211 can drive the clamping member 1212 to reciprocate in the vertical direction to approach or move away from the conduit 200 through the second sliding part. The clamping component 121 has a plurality of clamping members 1212, and the plurality of clamping members 1212 correspond one by one to the plurality of limiting clips 1222.
[0046] Specifically, the clamping member 1212 approaches or moves away from the conduit 200 under the drive of the second movable cylinder 1211. The clamping component 121 includes a plurality of clamping members 1212. The plurality of clamping members 1212 are arranged side by side along the arrangement direction of the plurality of conduits 200. The plurality of clamping members 1212 correspond one by one to the plurality of conduits 200 and at the same time correspond one by one to the plurality of limiting clips 1222, so that the tail section of each conduit 200 can be limited and fixed by the limiting clips 1222, and the position movement can be realized through the common cooperation of the clamping member 1212 and the limiting clips 1222 to adjust its setting position on the carrier 210 and prepare for entering the subsequent workstations.
[0047] In an implementable manner of the present application, as Figure 1 and Figure 3As shown, the infusion set catheter placement correction device 100 further includes a support mechanism 130. The support mechanism 130 includes a first support frame 131 and a second support frame 132, and the first support frame 131 and the second support frame 132 are perpendicularly connected. A receiving cavity is provided in the middle section of the first support frame 131, and the receiving cavity is used to place the tube straightening mechanism 110. The first movable cylinder 1221 of the limit assembly 122 and the second movable cylinder 1211 of the clamping assembly 121 are both mounted on the second support frame 132.
[0048] Specifically, the infusion set catheter placement correction device 100 further includes a support mechanism 130, and the support mechanism 130 provides support for the settings of the tube straightening mechanism 110, the limit assembly 122, and the clamping assembly 121. As Figure 1 shown, the first support frame 131 includes a plurality of support columns, and the plurality of support columns enclose to form a receiving cavity, and the receiving cavity is used to place the tube straightening mechanism 110. To improve the connection stability of the first support frame 131, reinforcing ribs are further connected between adjacent support columns. The second support frame 132 has a hollow rectangular structure, and it is perpendicularly arranged with the second support frame 132 and partially extends to protrude from the first support frame 131 to separate the movement spaces of the tube straightening mechanism 110, the limit assembly 122, and the clamping assembly 121. The first movable cylinder 1221 of the limit assembly 122 and the second movable cylinder 1211 of the clamping assembly 121 are both mounted on the second support frame 132. The first movable cylinder 1221 can drive the limit clip 1222 to move downward to limit the tail section of the catheter 200, and the second movable cylinder 1211 can drive the clamping member 1212 to move downward to clamp the catheter 200.
[0049] Optionally, a slide rail and a third movable cylinder (not shown in the figure) are provided on the edge of the second support frame 132. The third movable cylinder includes a third sliding part, and the third sliding part is fixedly connected to the cylinder body of the first movable cylinder 1221 of the limit assembly 122. The third movable cylinder can drive the third sliding part to reciprocate along the slide rail to drive the first movable cylinder 1221 to drive the limit clip 1222 and the pressing block 1223 to move horizontally relative to the clamping assembly 121. The limit clip 1222 and the pressing block 1223 can limit the tail section of the catheter 200 and move along the side away from the clamping assembly 121 to straighten the catheter 200.
[0050] Specifically, in order to ensure that the clamping member 1212, the pressing block 1223, and the limit clamp 1222 can keep the catheter 200 in a straightened state when transferring the catheter 200 to the corresponding position of the carrier 210, a slide rail and a third moving cylinder are further provided on the edge of the second support frame 132. The third moving cylinder can drive the limit assembly 122 to slide along the slide rail to approach or move away from the clamping assembly 121. After the tail section of the catheter 200 is limited and fixed by the separation grooves 1224 on the limit clamp 1222 and the pressing block 1223, the clamping member 1212 can clamp the catheter 200. At this time, the third moving cylinder drives the limit clamp 1222 and the pressing block 1223 to move towards the side away from the clamping member 1212 to further straighten the catheter 200 and keep the catheter 200 in a straightened state all the time.
[0051] In an implementable manner of the present application, as Figure 2 shown, the infusion catheter placement position correction device 100 further includes a sheath tightening mechanism 140. The sheath tightening mechanism 140 is arranged on the edge of the first support frame 131 of the support mechanism 130. The sheath tightening mechanism 140 includes a fourth moving cylinder 141 and a push plate 142. The fourth moving cylinder 141 includes a fourth sliding part. The push plate 142 is fixedly connected to the fourth sliding part. The fourth moving cylinder 141 can drive the push plate 142 to reciprocate in the horizontal direction through the fourth sliding part so that the push plate 142 approaches or moves away from the end of the catheter 200. The tail section of the catheter 200 is placed on the carrier 210 through the catheter placement mechanism 120. The fourth moving cylinder 141 can drive the push plate 142 to tighten the sheath 201 sleeved on the catheter 200.
[0052] Specifically, a sheath 201 is sleeved on the outer wall of the catheter 200.
