Description

Technical Field

[0001] This utility model relates to the field of high-pressure angiography equipment technology, and in particular to a soft catheter feeding 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 is displayed using certain instruments, such as iodine preparations and barium sulfate commonly used in X-ray observation.

[0003] 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 through percutaneous puncture into blood vessels or through existing body orifices within a certain time, enabling diagnostic contrast imaging and treatment of lesions.

[0004] 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, the operator immerses one end of the flexible catheter in adhesive, then attaches the adhesive-soaked end of the catheter to 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. Therefore, an automated production line is needed to automate the assembly of flexible catheters and one-way valves. Specifically, a flexible catheter feeding device is required to automate the batch feeding of the assembled catheters. Utility Model Content

[0026] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0027] like Figure 1 As shown, a flexible conduit feeding device includes a feeding drive mechanism, and a distribution platform 13 is arranged below the feeding drive mechanism. The feeding mechanism and the picking mechanism are connected to the moving end of the feeding drive mechanism. When the feeding drive mechanism is working, it can drive the picking mechanism to transport the flexible conduit to the distribution platform 13 for temporary storage. At the same time, the feeding drive mechanism drives the feeding mechanism to transport the flexible conduit temporarily stored on the distribution platform 13 to the flexible conduit assembly line.

[0028] like Figure 1 and Figure 2 As shown, the feeding drive mechanism includes a horizontally arranged linear slide 1, with its left and right ends fixed to the tops of a first mounting bracket 2 and a second mounting bracket 3, respectively. A translation mounting frame 4 is detachably connected to the moving end of the linear slide 1 via bolts.

During operation, the linear slide 1 drives the feeding mechanism and the picking mechanism to move synchronously, the first lifting cylinder 5 drives the feeding mechanism to move up and down, and the second lifting cylinder 6 drives the picking mechanism to move up and down.

[0029] like Figure 2 and Figure 3As shown, the feeding mechanism includes a first mounting plate 7. The upper end of the first mounting plate 7 is detachably connected to the drive end of the first lifting cylinder 5 via bolts. The lower end of the first mounting plate 7 is fixedly connected to two first cylinder mounting brackets 14. Four first gripper cylinders 9 are arranged side by side on the lower end of the first cylinder mounting brackets 14. Each first gripper cylinder 9 has two gripping ends connected to a first clamping plate 10. The two first clamping plates 10 of each first gripper cylinder 9 can cooperate to clamp a soft conduit.

Long strip-shaped adjustment holes are provided along the front-to-back direction of the adjustable material storage bracket 20, allowing adjustment of its front-to-back position. The fixed and adjustable material storage brackets 19 and 20 together provide positioning and support for the flexible conduit, and the adjustable material storage brackets 20 can be adjusted in their front-to-back position to adjust the position of the support point for the flexible conduit.

[0033] like Figure 5As shown, a limiting baffle 21 is set on the front and rear sides of the material distribution platform 13. The driving end of the limiting cylinder 22 is connected to the limiting baffle 21. The cylinder body of the limiting cylinder 22 is fixed on the lower end face of the material distribution platform 13. The limiting baffle 21 moves back and forth under the drive of the limiting cylinder 22, so as to achieve the effect of the front and rear ends of the multiple soft tubes placed on the material distribution platform 13 being flush.

[0034] like Figure 1 As shown, a material distribution mechanism is provided on one side of the material distribution platform 13. The material distribution mechanism is located directly above the material bin. The material bin is used to store and stack soft tubing. The material distribution mechanism can separate individual soft tubing from the soft tubing stacked in the material bin and wait for the material retrieval mechanism to come and retrieve the individual soft tubing.

[0035] like Figure 6 As shown, the material distribution mechanism includes a fixed bracket 23, which is detachably connected to a second mounting bracket 3 by bolts. A transverse plate 25 is provided on the lower end face of the fixed bracket 23. The transverse plate 25 is slidably connected to a linear guide rail by a slider, and the linear guide rail is fixed to the lower end face of the transverse plate 25. The drive end of a transverse cylinder 24 is connected to the transverse plate 25, and the transverse cylinder 24 is fixed inside the fixed bracket 23. The transverse cylinder 24 can push the transverse plate 25 to move laterally to adjust its position. A material distribution cylinder 26 is vertically fixed on the lower end face of the transverse plate 25. The drive end of the material distribution cylinder 26 is connected to a material distribution lifting plate 27. Two guide sleeves 29 are fixed on the material distribution lifting plate 27. The two guide sleeves 29 are symmetrically arranged on the left and right sides of the material distribution lifting plate 27. A guide rod 30 is slidably connected inside each of the two guide sleeves 29. The lower ends of the two guide rods 30 are respectively connected to the left and right ends of the material distribution nozzle mounting plate 28. The upper ends of the two guide rods 30 extend upwards through guide sleeves and connect to stop blocks 32. Stop blocks 32 prevent the guide rods 30 from falling out of the guide sleeves 29. Springs are fitted on the guide rods 30, with the upper end of the springs contacting the lower end face of the guide sleeves 29 and the lower end of the springs contacting the upper end face of the material distribution nozzle mounting plate 28.

[0036] like Figure 6 and Figure 7 As shown, four distributing air nozzles 31 are arranged side by side on the distributing air nozzle mounting plate 28. A circular arc-shaped distributing groove 33 is provided at the lower end of each distributing air nozzle 31. A vacuum adsorption port 34 is provided inside the distributing groove 33, and a vacuum adsorption channel is provided inside each distributing air nozzle 31. One end of the vacuum adsorption channel is connected to the vacuum adsorption port 34, and the other end is connected to an external vacuum pipeline. During operation, a vacuum adsorption force is generated within the vacuum adsorption port 34, adsorbing a single flexible tube into the distributing groove 33, thus achieving the separation of a single flexible tube from the hopper.

[0037] The working principle of this invention is as follows: During the assembly of the flexible conduit and the one-way valve, the flexible conduit is stacked and stored in the hopper. First, the material distribution mechanism operates, with the material distribution cylinder 26 driving multiple material distribution nozzles 31 to descend into the hopper. Each material distribution nozzle adsorbs a single flexible conduit into the material distribution trough 33. Then, the material distribution cylinder 26 drives the multiple material distribution nozzles 31 to lift multiple individual flexible conduits to a certain height, achieving the separation of the material-picking flexible conduit and the material-storing flexible conduit, facilitating subsequent automatic material picking and loading. Next, the loading drive mechanism drives the picking mechanism from the material distribution platform 13 to the material distribution mechanism and clamps the flexible conduit separated from the material distribution mechanism. Simultaneously, the loading drive mechanism synchronously drives the loading mechanism from the assembly line position to the material distribution platform 13 and grabs the flexible conduit placed on the material distribution platform 13. At this time, the feeding drive mechanism drives the picking mechanism and the feeding mechanism to move back to their original positions. The picking mechanism moves the gripped soft tube from the position of the distributing mechanism to the distributing platform 13, and the feeding mechanism moves the gripped soft tube from the distributing platform 13 to the assembly line.

[0038] The above description is an explanation of the present utility model and not a limitation thereof. The scope of the present utility model is defined by the claims. Within the protection scope of the present utility model, any form of modification may be made.
