Description

Technical Field

[0001] This invention relates to the field of flexible catheter assembly technology, and in particular to a flexible catheter assembly device. Background Technology

[0002] Contrast agents are chemical products injected into human tissues or organs to enhance the effect of image observation. These products have a higher or lower density than the surrounding tissues, and the contrast created is displayed using certain instruments. Examples include iodine preparations and barium sulfate commonly used in X-ray observation. High-pressure contrast injection systems, as auxiliary equipment in radiological diagnostic and treatment systems, have gradually been applied clinically with the development of technologies such as X-rays, rapid film changers, image intensifiers, and artificial contrast agents. High-pressure contrast injection systems can rapidly and accurately inject a sufficient amount of high-concentration X-ray contrast agent into the examination site within a certain time frame, either percutaneously through a blood vessel or through existing body orifices. This allows for diagnostic imaging and treatment of lesions.

[0003] The flexible catheters used in high-pressure contrast injection systems require the assembly of one-way valves. Currently, this assembly is primarily done manually. First, one end of the flexible catheter is immersed in adhesive. Then, the adhesive-soaked end of the catheter is fitted onto one end of the one-way valve, thus securing the valve and catheter together. Manual assembly is not only inefficient but also makes it difficult to guarantee installation quality, easily resulting in too much or too little adhesive. Too little adhesive leads to unreliable fixation and loosening during use; too much adhesive causes overflow, affecting the normal operation of the one-way valve and the flexible catheter.

[0032] The specific embodiments of the present invention will now be described with reference to the accompanying drawings.

[0033] like Figure 1 As shown, a flexible catheter assembly device includes a flexible catheter clamping mechanism 100, which is capable of clamping the flexible catheter being assembled.

[0034] like Figure 2 , Figure 3 and Figure 4As shown, the flexible catheter clamping mechanism 100 includes a vertically arranged fixed bracket 101. An upper clamp 104 and a lower clamp 108 are correspondingly arranged on the fixed bracket 101. The upper end of the upper clamp 104 is detachably connected to an upper lifting plate 103 via a connector. The upper lifting plate 103 is connected to the drive end of an upper lifting cylinder 102, which is vertically fixed to the fixed bracket 101. Two upper sliders are connected to the side of the upper clamp 104, and these two sliders are slidably connected to two upper slide rails 105, which are fixed to the fixed bracket 101. The lower end of the lower clamp 108 is detachably connected to a lower lifting plate 107 via a connector. The lower lifting plate 107 is connected to the drive end of a lower lifting cylinder 106, which is vertically fixed to the fixed bracket 101. The lower clamp 108 has two lower sliders connected to its side. The two lower sliders are slidably connected to two lower slide rails 109, and the two lower slide rails 109 are fixed to the fixed bracket 101.

[0035] like Figure 4 As shown, a collection chamber 110 is located directly below the lower clamp 108. The collection chamber 110 can collect flexible conduits or one-way valves that are not clamped by the upper clamp 104 and the lower clamp 108. The cross-sectional dimension of the upper opening of the collection chamber 110 is larger than the cross-sectional dimension of the lower clamp 108, and the cross-sectional dimension of the upper opening of the collection chamber 110 is larger than the cross-sectional dimension of the lower opening. A storage chamber 111 is located directly below the collection chamber 110. Items that fall into the collection chamber 110 are collected and stored through the storage chamber 111.

[0036] like Figure 5 As shown, the upper clamp 104 includes an upper clamping plate 113, which is bolted to an upper clamping plate mounting plate 112, which is fixed to an upper lifting plate 103. The lower part of the upper clamping plate 113 has an upper mating end face, and multiple through-hole upper clamping grooves are provided on the upper mating end face. The lower clamp 108 includes a lower clamping plate 115, which is bolted to a lower clamping plate mounting plate 114, which is fixed to a lower lifting plate 107. The upper part of the lower clamping plate 115 has a lower mating end face, and multiple through-hole lower clamping grooves are provided on the lower mating end face. These lower clamping grooves correspond one-to-one with the upper clamping grooves. The upper mating end face can contact the lower mating end face. When the upper and lower mating end faces are in contact, the upper and lower clamping grooves connect to form a circular clamping hole 116.

[0037] The upper clamping plate 113 and the lower clamping plate 115 are multi-layered plate structures with different heights between adjacent layers. When the upper clamping plate 113 and the lower clamping plate 115 are connected, they form an interlocking structure, which improves the stability of the upper clamping plate 113 and the lower clamping plate 115 during clamping.

[0038] When the flexible conduit clamping mechanism 100 is in operation, the upper lifting cylinder 102 and the lower lifting cylinder 106 respectively drive the upper clamp 104 and the lower clamp 108 to clamp the flexible conduit on the assembly line, ensuring that the flexible conduit remains stable when the one-way valve is assembled with the flexible conduit.

[0039] like Figure 1 As shown, a glue-applying mechanism 300 is provided on one side of the flexible catheter clamping mechanism 100. The glue-applying mechanism 300 can be used to apply glue to the end of the flexible catheter.

[0040] like Figure 3 and Figure 6 As shown, the glue application mechanism 300 includes a glue application mounting bracket 301. A glue application lifting cylinder 302 is vertically fixed on the glue application mounting bracket 301. The drive end of the glue application lifting cylinder 302 is connected to a glue application lifting bracket 303. Two lifting sliders are connected to the side of the glue application lifting bracket 303, and the two lifting sliders are slidably connected to two lifting slide rails, which are fixed to the side of the glue application mounting bracket 301. A glue application translation cylinder 305 is horizontally fixed to the lower end face of the glue application lifting bracket 303. The drive end of the glue application translation cylinder 305 is connected to a glue application translation bracket 304. Two horizontal sliders are provided at the bottom of the glue application translation bracket 304, and the two horizontal sliders are slidably connected to two horizontal slide rails, which are fixed to the upper end face of the glue application lifting bracket 303. A glue box 306 is fixed to the upper end face of the glue application translation bracket 304, and the glue box 306 is filled with glue.

[0041] like Figure 6 As shown, four glue-applying rollers 311 are arranged side-by-side inside the glue box 306. The rollers 311 are rotatably connected to bearing seats 307 via bearings, and the bearing seats 307 are fixed to the upper surface of the glue-applying translation bracket 304. A transmission gear 310 is connected to the rear end of each of the four rollers 311, and the four transmission gears 310 are sequentially meshed. A drive motor 309 is mounted on one side of each of the four transmission gears 310 and is fixed to a motor mounting plate 308. The drive end of the drive motor 309 is connected to a drive gear 313, which meshes with any one of the four transmission gears 310. When the drive motor 309 is working, it drives the four transmission gears 310 to rotate via the drive gear 313, and the four transmission gears 310 respectively drive the glue-applying rollers 311 to rotate. A glue-applying disc 312 is fitted onto the front end of each roller 311.

[0042] like Figure 8As shown, an axially penetrating glue-applying hole 314 is provided at the center of the glue-applying tray 312. During use, the end of the flexible conduit is positioned and inserted into the glue-applying hole 314 to apply glue to the outer wall of the conduit. The glue-applying tray 312 is provided with four radially extending glue inlet holes 315. One end of the glue inlet hole 315 extends to the inner ring of the glue-applying tray 312 and communicates with the glue-applying hole 314, while the other end of the glue inlet hole 315 extends to the outer ring surface of the glue-applying tray 312. Glue can enter from the glue inlet hole 315 and eventually flow into the glue-applying hole 314 as the glue-applying tray 312 rotates.

[0043] like Figure 8 As shown, a protruding support sleeve 316 is provided at the center of the front end of the glue applicator 312, and an installation hole is provided at the front end of the glue box 306, with the support sleeve 316 placed in the installation hole.

[0044] like Figure 7 As shown, a positioning post 317 is provided at the center of the front end face of the coating roller 311, and four annular sealing ribs 318 are provided on the outer ring of the front end face of the coating roller 311 along the circumferential direction. When the flexible conduit extends into the coating hole 314 for coating, the end of the flexible conduit contacts the front end face of the coating roller 311, the positioning post 317 extends into the inner hole of the flexible conduit for sealing and positioning, and the inner wall of the sealing ribs 318 contacts the outer wall of the flexible conduit to prevent the glue in the coating hole 314 from entering the inner hole of the flexible conduit and affecting the subsequent use of the flexible conduit.

[0045] When the glue application mechanism 300 is in operation, the glue application lifting cylinder 302 first moves the glue box 306 to the height position of the flexible tube held by the flexible tube clamping mechanism 100. Then, the glue application translation cylinder 305 moves the glue box 306 closer to the end of the flexible tube until the end of the flexible tube extends into the glue application hole 314 of the glue application tray 312. The front end face of the flexible tube contacts the front end face of the glue application roller 311. The inner hole of the glue application hole 314 is sealed by the positioning post 317 and the sealing rib 318 to prevent glue in the glue application hole 314 from entering the inner hole of the flexible tube and affecting the subsequent use of the flexible tube. At this time, the drive motor 309 drives the glue application tray 312 and the glue application roller 311 to rotate synchronously. The glue in the glue box 306 enters the glue application hole 314 along the glue inlet hole 315 of the glue application tray 312, and with the rotation of the glue application tray 312, the glue is applied to the entire outer surface of the flexible tube.

[0046] like Figure 1 As shown, a one-way valve feeding mechanism 500 is provided on one side of the glue application mechanism 300, which can realize the sequential feeding of one-way valves. A one-way valve picking mechanism 400 is provided between the one-way valve feeding mechanism 500 and the flexible conduit clamping mechanism 100. The one-way valve picking mechanism 400 can grab the one-way valve in the one-way valve feeding mechanism 500 and transport it to the position of the flexible conduit clamping mechanism 100 to complete the assembly with the flexible conduit.

[0047] like Figure 1As shown, the one-way valve feeding mechanism 500 includes a vibrating feeding plate 501 for storing one-way valves. Multiple vibrating feeding tracks 502 are arranged side by side at the discharge end of the vibrating feeding plate 501. The multiple feeding tracks 502 are connected to a straight vibrator 503, which is fixed on a mounting base 504.

[0048] When the one-way valve feeding mechanism 500 is working, the vibrating feeding plate 501 can sequentially transport the one-way valves to multiple vibrating feeding tracks 502, and the multiple vibrating feeding tracks 502 can then simultaneously transport multiple one-way valves to the discharge end position.

[0049] like Figure 10 As shown, the one-way valve material handling mechanism 400 includes a slide table mounting bracket 401. A linear slide table 402 is horizontally arranged on the slide table mounting bracket 401. The drive end of the linear slide table 402 is connected to a translation mounting frame 403. A material handling lifting cylinder 404 is vertically arranged on the translation mounting frame 403. The drive end of the material handling lifting cylinder 404 is connected to a material handling lifting plate 405. Two material handling lifting sliders are connected to the side of the material handling lifting plate 405. The two material handling lifting sliders are slidably connected to two material handling lifting slide rails, which are fixed to the translation mounting frame 403. The left and right ends of the material handling mounting frame 413 are respectively connected to a first mounting support plate 409 and a second mounting support plate 410. A rotating bracket 411 is arranged between the first mounting support plate 409 and the second mounting support plate 410. Rotating shafts are connected to both ends of the rotating bracket 411. The two rotating shafts are rotatably connected to the first mounting support plate 409 and the second mounting support plate 410, respectively. A drive cylinder mounting plate 406 is fixed on the material handling mounting frame 413. A rotary drive cylinder 407 is horizontally fixed on the drive cylinder mounting plate 406. The drive end of the rotary drive cylinder 407 is rotatably connected to one end of the drive plate 408 via a pin. The other end of the drive plate 408 is fixedly connected to one of two rotating shafts. When the rotary drive cylinder 407 is working, it can drive one end of the drive plate 408 to move back and forth, thereby driving the rotating shaft at the other end of the drive plate 408 to rotate. The rotating shaft in turn drives the rotary support 411 to rotate. Multiple material handling cylinders 412 are arranged side by side on the rotary support 411. Each material handling cylinder 412 is a gripper cylinder, and each material handling cylinder 412 can grip one one-way valve.

[0050] When the one-way valve picking mechanism 400 is working, the picking cylinder 412 can grab the one-way valve on the one-way valve positioning mechanism 600, rotate the one-way valve which is in a vertical state by 90° to become a horizontal state, and then send the one-way valve into one end of the soft tube of the soft tube clamping mechanism 100 to realize the assembly of the soft tube and the one-way valve.

[0051] like Figure 1As shown, a check valve positioning mechanism 600 is provided at the discharge end of the check valve feeding mechanism 500. The check valve positioning mechanism 600 can adjust the angle position of the check valve to ensure that the check valve can be accurately connected with the flexible conduit.

[0052] like Figure 1 and Figure 11 As shown, the one-way valve positioning mechanism 600 includes a positioning mounting bracket 601. A positioning transverse cylinder 602 is fixed on the positioning mounting bracket 601. The drive end of the positioning transverse cylinder 602 is connected to a transverse push plate 603. A transverse mounting plate 604 is connected to the transverse push plate 603. Multiple positioning sliders are connected to the bottom of the transverse mounting plate 604. The multiple positioning sliders are slidably connected to the same positioning slide rail, which is fixed to the upper surface of the positioning mounting bracket 601. A positioning connecting plate 606 is detachably connected to the upper end of the transverse mounting plate 604 via a connector. A positioning plate 605 is detachably connected to the upper end of the positioning connecting plate 606 via a connector. Four vertically penetrating positioning holes are arranged side by side in the positioning plate 605. A positioning support shaft 608 is arranged at the lower part of each positioning hole. The middle part of the positioning support shaft 608 is rotatably connected to a positioning bearing seat 607 via a bearing. The positioning bearing seat 607 is fixed to the side of the positioning connecting plate 606. A positioning support shaft 608 is connected to a positioning transmission gear 609 at its lower part. The four positioning transmission gears 609 at the lower part of the four positioning support shafts 608 are sequentially meshed. A positioning drive cylinder 610 is fixed to the side of the positioning bearing seat 607. The drive end of the positioning drive cylinder 610 is connected to a positioning drive plate 611. A positioning transmission rack 612 is fixed on the positioning drive plate 611. A positioning drive gear 613 is connected to the lower part of any one of the four positioning support shafts 608. The positioning drive gear 613 and the positioning transmission rack 612 are meshed. The positioning drive cylinder 610 can drive one positioning support shaft 608 to rotate through the meshing positioning transmission rack 612 and positioning drive gear 613. One positioning support shaft 608, in turn, drives the other three positioning support shafts 608 to rotate synchronously through the meshing positioning transmission gears 609. A guide slider is connected to the side of the positioning drive plate 611. The guide slider is slidably connected to a guide rail, which is fixed to the side of the positioning bearing seat 607.

[0053] like Figure 12 As shown, a transversely penetrating positioning groove 614 is provided at the upper end of the positioning support shaft 608. When the check valve enters the positioning hole, the middle part of the check valve is supported by the upper end face of the positioning support shaft 608, and the lower part of the check valve enters the positioning groove 614. When the positioning support shaft 608 rotates, it can make one side of the groove end face of the positioning groove 614 contact the fin end face of the lower part of the check valve. When one side of the groove end face of the positioning groove 614 contacts the fin end face of the lower part of the check valve, it can drive the check valve to rotate, ultimately ensuring that the check valve is grasped by the check valve picking mechanism 400 in the set state position.

[0054] When the one-way valve positioning mechanism 600 is working, the one-way valves are sequentially fed into the positioning holes by the one-way valve feeding mechanism 500, and the one-way valves inside the positioning holes are supported by the positioning support shaft 608. At this time, the positioning drive cylinder 610 drives the positioning support shaft 608 to rotate through the gear and rack mechanism. When the positioning support shaft 608 rotates, it allows one side of the positioning transverse groove 614 to contact the fin end face of the lower part of the one-way valve. When one side of the positioning transverse groove 614 contacts the fin end face of the lower part of the one-way valve, it can drive the one-way valve to rotate, ultimately making the feeding position of the one-way valves in all positioning holes consistent.

[0055] like Figure 1 As shown, the flexible catheter clamping mechanism 100 is provided with a clamping mechanism 200, which can clamp the flexible catheter to ensure that the one-way valve and the flexible catheter can be reliably bonded and fixed.

[0056] like Figure 13 As shown, the clamping mechanism 200 includes a clamping fixing bracket 201. A clamping lifting cylinder 202 is vertically fixed on the side of the clamping fixing bracket 201. The driving end of the clamping lifting cylinder 202 is connected to a clamping lifting plate 203. A clamping cylinder 204 is horizontally fixed on the clamping lifting plate 203. The clamping cylinder 204 is a gripper cylinder. The two clamping ends of the clamping cylinder 204 are respectively connected to a clamping plate 205. Four clamping fingers 206 are arranged side by side on the two clamping plates 205. The two sets of clamping fingers 206 on the two clamping plates 205 are arranged one-to-one and can cooperate to clamp a soft tube.

[0057] The above description is an explanation of the present invention and not a limitation thereof. The scope of the present invention is defined by the claims. Within the scope of protection of the present invention, any form of modification may be made.
