Detailed Description

The following describes embodiments of the present invention with reference to the drawings.

As shown in figure 1, the catheter for iodine staining comprises a pushing part 1, a barrel body 2, a connecting part 3 and a catheter body 4.

As shown in fig. 2 and 3, the pushing portion 1 includes a handle 13, a connecting rod 11 and a connecting sleeve 5, the connecting rod 11 is disposed on the handle 13, the slidable connecting sleeve 5 is disposed on the outer side of the connecting rod 11, a sliding groove 111 is disposed in the connecting rod 11, a slidable piston 61 is disposed in a piston cavity 21 of the cylinder 2, iodine solution is filled in the piston cavity 21, the piston 61 and the piston cavity 21 are hermetically connected, a push rod 62 is disposed on the piston 61, the push rod 62 can extend out of the piston cavity 21, when the connecting sleeve 5 is connected to the head end of the cylinder 2, the sliding groove 111 is in threaded connection with the push rod 62, the connecting rod 11 is driven to rotate by the handle 13 during operation, the push rod 62 drives the piston 61 to move downward along the sliding groove 111 by using a thread engagement force between the push rod 62 and the sliding groove 111, at this time, the piston 61 pushes the iodine solution in the piston cavity 21 downward, the iodine solution flows out from an opening 22 at the tail end of the cylinder 2, and the discharge amount of the iodine solution is controlled by rotating the handle 13, which is more precise than the conventional pushing and does not cause a risk of miscarriage of a large amount of iodine solution, thereby reducing the stimulation of a human body.

Further, as shown in fig. 2 and 3, the head end of the connecting sleeve 5 is detachably connected with the head end of the cylinder 2 through threads, the connecting rod 11 is provided with a limiting sleeve 12 at one end away from the handle 13, the tail end of the connecting sleeve 5 is provided with a snap ring 52, the diameter of the snap ring 52 is between the diameter of the connecting rod 11 and the diameter of the limiting sleeve 12, the limiting sleeve 12 is utilized to limit the snap ring 52, the connecting sleeve 5 can be prevented from being separated from the connecting rod 11 in the sliding process, the connection stability of the connecting rod 11 and the cylinder 2 is ensured, the sliding groove 111 and the push rod 62 can be smoothly connected through threads, the push rod 62 is driven and the piston 61 is positioned in the piston cavity 21 of the cylinder 2 to slide, and the iodine solution is discharged. And when the cylinder 2 needs to be cleaned, the pushing part 1 can be taken down from the cylinder 2 by rotating the connecting sleeve 5, and then the piston 61 is pulled out from the piston cavity 21 by the push rod 62, so that the cylinder 2 and the piston 61 are disassembled, and the cylinder 2 and the piston 61 can be cleaned quickly.

As shown in fig. 4, 5 and 6, the joining portion 3 includes a base 31 and a conical head 32 disposed on the base 31, and through holes 33 are respectively formed on the base 31 and the conical head 32, when the conical head 32 is inserted into the end of the cylinder 2, the through holes 33 are communicated with the piston cavity 21, the tube body 4 is composed of an inner tube 41 and an outer tube 42, the head end of the inner tube 41 is connected to the through holes 33, and after the iodine solution flows out from the opening 22, the iodine solution flows into the inner tube 41 through the through holes 33, and then flows into the esophagus through the inner tube 41 to perform iodine staining. Further, an outer tube 42 is sleeved outside the inner tube 41, and the end of the inner tube 41 is wrapped in the outer tube 42, because the outer tube 42 is made of a flexible material such as: the silica gel is made of silicon gel, and compared with the traditional iodine-staining catheter, the texture is smoother and softer, so that the esophagus is not easily scratched in the iodine-staining process to damage the esophagus, and the safety of the esophagus is protected.

Further, as shown in fig. 5 and 6, the conical head 32 is detachably connected to the end of the cylinder 2, specifically, the conical head 32 is of a conical structure, when the end with a small diameter on the conical head 32 is inserted into the opening 22 of the cylinder 2, the gap between the conical head 32 and the opening 22 is gradually reduced until the conical head 32 is tightly attached to the inner wall of the opening 22, and then the conical head 32 is used to clamp the opening 22, so as to achieve the fixed connection between the connection part 3 and the cylinder 2, reduce the risk that the conical head 32 is unintentionally separated from the opening 22 during use, and avoid leakage of iodine solution in the piston cavity 21 of the cylinder 2, and when the iodine solution in the piston cavity 21 needs to be replenished, the conical head 32 can be forcibly pulled out from the opening 22, and then the opening 22 of the cylinder 2 is immersed in the external iodine solution, and then the handle 13 is rotated to move the piston 61 and the push rod 62 upward, at this time, the lower side of the piston 61 is in a negative pressure state, and the external iodine solution is sucked into the piston cavity 21 from the opening 22, so as to quickly complete replenishment of the iodine solution. In addition, as shown in fig. 6, a spring ring 7 is slidably disposed in the piston cavity 21, the spring ring 7 is disposed between the piston 61 and the conical head 32, and the spring ring 7 is sleeved outside the conical head 32, when the piston 61 covers one end of the spring ring 7, a gap is formed between the piston 61 and the conical head 32, and by using the limiting effect of the spring ring 7 on the piston 61, the piston 61 is prevented from being extruded to the conical head 32 in the downward movement and retraction processes, and the conical head 32 is prevented from being pushed out of the opening 22, so that the connection stability of the conical head 32 and the cylinder 2 is enhanced.

When using, send the body 4 into the esophagus through the endoscope earlier, it rotates to drive connecting rod 11 through handle 13 again, utilize the thread engagement power between push rod 62 and the spout 111, make push rod 62 drive piston 61 along spout 111 downstream, piston 61 promotes the iodine solution in the piston chamber 21 downwards this moment, the iodine solution flows in through-hole 33 from the terminal opening 22 of barrel 2, then pass through-hole 33 and flow to in the inner tube 41, flow to carrying out the iodine dyeing in the esophagus via inner tube 41, because the iodine solution discharge amount is controlled through rotating handle 13, the accuse volume that bulldozes for traditional cylinder will be more accurate, and can not have the risk that the wrong pressure handle 13 leads to a large amount of effluvium of iodine solution, realize the micro-operation of iodine solution, reduce the stimulation that the human body received, the terminal parcel of inner tube 41 is smooth simultaneously, soft outer tube 42, make difficult in the iodine dyeing process cause the scratch to the esophagus, harm the esophagus, thereby protect the safety. Simple structure, the simple operation realizes the micro-operation of iodine liquid through the emission of iodine liquid in the little twist grip 13 accurate control barrel 2, reduces the stimulation that the human body received, and in addition, the inner tube 41 end is wrapping up smooth, mild outer tube 42 for dye the in-process at iodine and be difficult for causing the scratch to the esophagus, harm the esophagus, thereby protection esophagus safety.

The aforesaid is only the embodiment of the present invention, but the design concept of the present invention is not limited to this, and it is right to utilize this concept the present invention to perform insubstantial modification, and all belong to infringement the protection scope of the present invention.
