Description

Technical Field

[0001] The invention relates to the technical field of soft catheter assembly, in particular to a soft catheter assembly device. Background Art

[0002] Contrast agents are chemicals injected into human tissues or organs to enhance the effect of image observation. The density of these products is higher or lower than that of surrounding tissues, and the contrast formed is used to display images with certain instruments, such as iodine preparations and barium sulfate commonly used in X-ray observation. As an auxiliary device in the radiological diagnosis and treatment system, the high-pressure contrast injection system is gradually used in clinical practice with the development of technologies such as X-rays, rapid film changers, image intensifiers, and artificial contrast agents. The high-pressure contrast injection system can quickly and accurately inject a sufficient amount of high-concentration X-ray contrast agents into the examination site through percutaneous puncture or through the original channels of the human body within a certain period of time, and can perform diagnostic imaging and treatment of the lesion site.

[0003] The soft catheter used in the high-pressure contrast injection system needs to be assembled with a one-way valve. In the prior art, the assembly is mainly performed manually. First, immerse one end of the soft catheter in glue, and then sleeve one end of the soft catheter with glue on one end of the one-way valve to achieve the gluing of the one-way valve and the soft catheter. Manual assembly not only has low work efficiency, but also makes it difficult to ensure the installation quality, and it is easy to have too much or too little glue. Too little glue will lead to unreliable fixation and easy loosening during use; too much glue will cause glue overflow, affecting the normal use of the one-way valve and the soft catheter.

[0031] like Figure 1 As shown, a soft catheter assembly device includes a soft catheter clamping mechanism 100, and the soft catheter clamping mechanism 100 can clamp the soft catheter to be assembled.

[0032] like Figure 2 , Figure 3 and Figure 4As shown, the flexible conduit clamping mechanism 100 includes a vertically arranged fixed bracket 101, on which an upper clamp 104 and a lower clamp 108 are arranged correspondingly at the upper and lower parts, and the upper end of the upper clamp 104 is detachably connected to the upper lifting plate 103 through a connecting piece, and the upper lifting plate 103 is connected to the driving end of the upper lifting cylinder 102, and the upper lifting cylinder 102 is vertically fixed on the fixed bracket 101. The upper clamp 104 is connected to two upper sliders on the side, and the two upper sliders are respectively slidably connected to two upper slide rails 105, and the two upper slide rails 105 are fixed on the fixed bracket 101. The lower end of the lower clamp 108 is detachably connected to the lower lifting plate 107 through a connecting piece, and the lower lifting plate 107 is connected to the driving end of the lower lifting cylinder 106, and the lower lifting cylinder 106 is vertically fixed on the fixed bracket 101. The side of the lower clamp 108 is connected to two lower sliders, and the two lower sliders are respectively slidably connected to two lower slide rails 109 , and the two lower slide rails 109 are fixed on the fixed bracket 101 .

[0033] like Figure 4 As shown, a collecting bin 110 is arranged directly below the lower clamp 108, and the collecting bin 110 can collect the soft conduit or the one-way valve that is not clamped by the upper clamp 104 and the lower clamp 108. The cross-sectional dimension of the upper opening of the collecting bin 110 is larger than the cross-sectional dimension of the lower clamp 108, and the cross-sectional dimension of the upper opening of the collecting bin 110 is larger than the cross-sectional dimension of the lower opening.

The upper matching end face can match and contact with the lower matching end face, and when the upper matching end face matches and contacts with the lower matching end face, the upper clamping groove and the lower clamping groove are connected to form a circular clamping hole 116.

[0035] The upper splint 113 and the lower splint 115 are multi-layer plate structures, and the height dimensions of the two adjacent layers of the plate bodies are different. When the upper splint 113 and the lower splint 115 are matched and connected, a staggered structural state is formed, which improves the stability of the upper splint 113 and the lower splint 115 when clamping.

[0036] When the soft conduit clamping mechanism 100 is working, the upper lifting cylinder 102 and the lower lifting cylinder 106 respectively drive the upper clamp 104 and the lower clamp 108 to cooperate in clamping the soft conduit on the assembly line, ensuring that the soft conduit remains in a stable state when the one-way valve is assembled with the soft conduit.

[0037] like Figure 1 As shown, a glue coating mechanism 300 is provided on one side of the soft catheter clamping mechanism 100, and the glue coating mechanism 300 can be used to coat glue on the end of the soft catheter.

[0038] like Figure 3 and Figure 6 As shown, the glue coating mechanism 300 includes a glue coating mounting bracket 301, on which a glue coating lifting cylinder 302 is vertically fixed, and the driving end of the glue coating lifting cylinder 302 is connected to a glue coating lifting bracket 303, and two lifting sliders are connected to the side of the glue coating lifting bracket 303, and the two lifting sliders are respectively slidably connected to two lifting rails, and the two lifting rails are fixed to the side of the glue coating mounting bracket 301.

A glue box 306 is fixed to the upper end surface of the glue coating translation bracket 304, and the glue box 306 is filled with glue.

When in use, the end of the soft tube is positioned and inserted into the glue coating hole 314 to coat the outer tube wall with glue. Four radially extending glue inlet holes 315 are provided on the glue coating disc 312. One end of the glue inlet hole 315 extends to the inner ring of the glue coating disc 312 and communicates with the glue coating hole 314. The other end of the glue inlet hole 315 extends to the outer ring surface of the glue coating disc 312. Glue can enter from the glue hole 315 and finally flow into the glue coating hole 314 as the glue coating disc 312 rotates.

The front end face of the soft tube contacts the front end face of the glue coating roller 311, and the inner hole of the glue coating hole 314 is sealed by the positioning column 317 and the sealing rib 318 to prevent the glue in the glue coating hole 314 from entering the inner hole of the soft tube and affecting the subsequent use of the soft tube. At this time, the driving motor 309 drives the glue coating disk 312 and the glue coating roller 311 to rotate synchronously, and the glue in the glue box 306 enters the glue coating hole 314 along the glue inlet hole 315 of the glue coating disk 312, and the glue is coated on the entire outer surface of the soft tube as the glue coating disk 312 rotates.
