Description

Technical Field

[0001] This utility model relates to the field of angiography catheter technology, specifically to an angiography catheter with an anti-loosening structure. Background Technology

[0002] Angiography catheters are key equipment for percutaneous angiography. They should possess appropriate rigidity, elasticity, flexibility, and torsional strength; good radiolucency; good shape memory; smooth walls; high contrast performance; and minimal thrombotic activity. An angiography catheter is a long rubber tube whose main function is to provide guidance for the smooth introduction of contrast agent into the blood vessel to produce the contrast effect. Therefore, an angiography catheter should meet the following basic requirements: a smooth inner tube capable of producing high flow rates; high contrast performance; a non-invasive tip with excellent shape retention and resistance to deformation; and the ability to accommodate guidewires for easy passage.

[0003] For example, the contrast catheter with an anti-loosening structure disclosed in the authorization announcement number CN217908582U, although it realizes a contrast catheter with an anti-loosening structure, including a connecting tubing, a telescopic tube at one end of the connecting tubing, a flexible expansion ball at the end of the telescopic tube away from the connecting tubing, an infusion head on the flexible expansion ball, a contrast fluid connecting tube at the end of the connecting tubing away from the telescopic tube, and a flexible hand guard on the connecting tubing, does not solve the problem that in the past contrast catheters with anti-loosening structures, when the catheter is delivered into the patient's body, it cannot effectively guarantee the stability of the catheter during delivery, and there may be side leakage during infusion. Utility Model Content

[0004] The purpose of this invention is to provide an angiography catheter with an anti-loosening structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An angiography catheter with an anti-loosening structure includes a main body structure. The main body structure includes a connecting sleeve, a top soft rubber tube, an expandable soft rubber tube, a bottom soft rubber tube, and an infusion port. The connecting sleeve has a top soft rubber tube fixedly attached to its bottom end, an expandable soft rubber tube fixedly attached to its bottom end, a bottom soft rubber tube fixedly attached to its bottom end, and an infusion port fixedly attached to its bottom end.

[0007] An auxiliary mechanism is fixedly installed at the top of the connecting sleeve. The auxiliary mechanism includes a push rod, an infusion tube, a mounting plate, and a leak-proof clamp. The auxiliary mechanism includes a push rod and an infusion tube. A mounting plate is fixedly installed at the bottom of the infusion tube, and a leak-proof clamp is fixedly installed at the bottom of the mounting plate.

[0008] Preferably, the connecting sleeve includes a threaded groove, and a leak-proof groove is fixedly provided at the bottom end of the threaded groove. The advantage is that the infusion tube can be effectively connected to the inside of the connecting sleeve through the threaded groove and the leak-proof groove, preventing side leakage during the delivery of contrast agent, which would cause waste and contamination of medical equipment. This effectively ensures the practicality of the catheter and its safety during use.

[0009] Preferably, the top soft tubing is fixedly provided with an inlet tube. The advantage is that by connecting the infusion tube, mounting plate and anti-leakage plate at the top, the developing solution will not leak to the side, and the infusion process will be kept smooth. This prevents the developing solution from accumulating inside the tubing and causing problems such as excessive retention, thus effectively ensuring its safety during use.

[0010] Preferably, the expandable soft tubing includes a liquid-retaining soft strip, and a liquid-retaining tube is fixedly disposed inside the liquid-retaining soft strip. The advantage is that during the infusion process, a portion of the contrast agent flows into the liquid-retaining tube. The contrast agent flowing into the liquid-retaining tube will expand the liquid-retaining soft strip. When expanded, it can effectively move the expandable soft layer on one side of the liquid-retaining soft strip, which can effectively fix the catheter in the patient's body and effectively prevent the catheter from slipping out of the patient's body, thus effectively ensuring the safety during use.

[0011] Preferably, an expanding soft rubber layer is fixedly provided on one side of the liquid storage soft rubber strip. The advantage is that the developing solution flowing into the liquid storage tube supports the liquid storage soft rubber strip. When it is supported, it can effectively drive the expanding soft rubber layer on one side of the liquid storage soft rubber strip, which can effectively fix the catheter in the patient's body, ensuring the stability of the catheter in the patient's body during use and preventing medical accidents that may occur due to catheter displacement in the patient's body during use.

[0012] Preferably, the push rod includes a handle, a connecting rod is fixedly provided at the bottom end of the protective handle, and a push plate is fixedly provided at the bottom end of the connecting rod. The advantage is that before infusion, medical staff can push the connecting rod at the bottom end through the handle, and then the connecting rod pushes the push plate at the bottom end to effectively deliver the angiography catheter into the patient's body. Moreover, it can effectively prevent the catheter from shifting randomly in the patient's body during delivery.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This contrast catheter with an anti-loosening structure allows medical staff to push the connecting rod at the bottom of the catheter via the handle before infusion. The connecting rod then pushes the push plate at the bottom, effectively delivering the contrast catheter into the patient's body. This prevents the catheter from shifting haphazardly within the patient's body during delivery. After delivery, the catheter can be connected using the mounting plate. Once connected, infusion can begin. During infusion, the threaded groove and leak-proof groove effectively secure the infusion tubing to the connecting sleeve, preventing side leakage and waste during contrast agent delivery. To address the issue of contaminating medical equipment, the contrast agent is then introduced into the patient's body through the infusion tube. As the contrast agent flows inside the infusion tube, some of it flows into the storage tube. This flow of contrast agent expands the storage tubing, effectively securing the catheter within the patient and preventing it from slipping out. After the infusion is complete, the contrast agent stored in the storage tubing also flows into the patient's body. The expansion tubing then contracts, and the catheter can be removed by pulling the infusion tubing after contraction.

[0015] 2. The advantages of this contrast catheter with an anti-loosening structure are that, in the past, contrast catheters with anti-loosening structures could not effectively guarantee the stability of the catheter during delivery to the patient, and side leakage may occur during infusion. Therefore, this contrast catheter with an anti-loosening structure is proposed. The push rod can effectively deliver the contrast catheter into the patient's body and effectively prevent the catheter from shifting randomly within the patient's body during delivery. Furthermore, the threaded groove and anti-leakage groove can effectively connect the infusion tube inside the connecting sleeve, preventing side leakage during the delivery of contrast solution, which would cause waste and contamination of medical equipment. This effectively ensures the practicality and safety of the catheter during use. Attached Figure Description

[0026] In this embodiment, preferably, the connecting sleeve 1 includes a threaded groove 10, and a leak-proof groove 11 is fixedly provided at the bottom end of the threaded groove 10. The advantage is that the infusion tube 7 can be effectively connected to the inside of the connecting sleeve 1 through the threaded groove 10 and the leak-proof groove 11, preventing side leakage and waste during the delivery of contrast agent, as well as the problem of contaminating medical equipment, thus effectively ensuring the practicality of the catheter and the safety during use.

[0027] In this embodiment, preferably, the top soft rubber conduit 2 is fixedly provided with an inlet pipe 12. The advantage is that by connecting the top infusion pipe 7, the mounting plate 8 and the leak-proof clamp 9, the developing solution will not leak to the side, and the infusion process will be kept normal. This will prevent the developing solution from accumulating inside the conduit and causing problems such as excessive retention, thus effectively ensuring its safety during use.

[0028] In this embodiment, preferably, the expandable soft tubing 3 includes a liquid-retaining soft tubing 13, and a liquid-retaining tube 14 is fixedly disposed inside the liquid-retaining soft tubing 13. The advantage is that during the infusion process, a portion of the contrast agent flows into the liquid-retaining tube 14. The contrast agent flowing into the liquid-retaining tube 14 will support the liquid-retaining soft tubing 13. When it is supported, it can effectively drive the expandable soft tubing layer 15 on one side of the liquid-retaining soft tubing, which can effectively fix the catheter in the patient's body and effectively prevent the catheter from slipping out of the patient's body, thus effectively ensuring the safety during use.

[0029] In this embodiment, preferably, an expanding soft rubber layer 15 is fixedly provided on one side of the liquid storage soft rubber strip 13. The advantage is that the developing solution flowing into the liquid storage tube 14 supports the liquid storage soft rubber strip 13. When it is supported, it can effectively drive the expanding soft rubber layer 15 on one side of the liquid soft rubber strip, which can effectively fix the catheter in the patient's body, ensuring the stability of the catheter in the patient's body during use and preventing medical accidents that may occur due to catheter displacement in the patient's body during use.

[0030] In this embodiment, preferably, the push rod 6 includes a handle 16, and a connecting rod 17 is fixedly provided at the bottom end of the protective handle 16. A push plate 18 is fixedly provided at the bottom end of the connecting rod 17. The advantage is that before infusion, medical staff can push the connecting rod 17 at the bottom end through the handle 16, and then the connecting rod 17 can push the push plate 18 at the bottom end to effectively deliver the angiography catheter into the patient's body. Moreover, it can effectively prevent the catheter from shifting randomly in the patient's body during delivery.

[0031] In this embodiment, an angiography catheter with an anti-loosening structure is used so that, before infusion, medical staff push the connecting rod 17 at the bottom by the handle 16, and the connecting rod 17 pushes the push plate 18 at the bottom to effectively deliver the angiography catheter into the patient's body. This effectively prevents the catheter from shifting haphazardly within the patient's body during delivery. After the catheter is delivered, it can be connected using the mounting plate 8. Once connected, the infusion can begin. During infusion, the threaded groove 10 and the leak-proof groove 11 effectively connect the infusion tube 7 to the inside of the connecting sleeve 1, preventing side leakage and waste, as well as contamination of medical equipment, during the delivery of contrast agent. Then, the contrast agent flows into the patient's body through the inlet tube 12. While flowing inside the inlet tube 12, some of the contrast agent flows into the storage tube 14. The contrast agent flowing into the storage tube 14 supports the storage soft rubber strip 13, effectively expanding the soft rubber layer 15 on one side of the soft rubber strip, thus effectively... The catheter is securely fixed inside the patient's body, effectively preventing it from slipping out. After the infusion is completed, the contrast agent stored inside the fluid-holding soft rubber strip 13 also flows into the patient's body. The expanding soft rubber tube 3 then contracts. After contraction, the catheter can be removed by pulling the infusion tubing 7. The advantage is that, in previous contrast catheters with anti-loosening structures, stability could not be effectively guaranteed during delivery, and side leakage was possible during infusion. Therefore, a contrast catheter with an anti-loosening structure was proposed. The push rod 6 effectively delivers the contrast catheter into the patient's body, preventing random displacement during delivery. The threaded groove 10 and leak-proof groove 11 effectively connect the infusion tubing 7 to the inside of the connecting sleeve 1, preventing side leakage and waste during contrast agent delivery, as well as contamination of medical equipment. This effectively ensures the practicality and safety of the catheter during use.
