Description

Technical Field

[0001] The utility model relates to the technical field of medical devices and is used for precise drug delivery to an affected area, in particular to a visual drug delivery catheter. Background Art

[0002] Drug administration is a routine operation in clinical practice, especially natural cavity drug administration and irrigation, which is a very common clinical treatment operation. The catheter is a medical device used in clinical practice to deliver drugs to the affected area through natural cavities (such as the esophagus, urethra, gastrointestinal tract, etc.) and artificial channels (such as tracheotomy channels, abdominal puncture, etc.).

[0003] While existing drug delivery catheters can deliver medication, they are unable to independently visualize the drug delivery process, achieve precise delivery, or control the delivery direction. They often require the assistance of other visual devices, such as endoscopes. Currently, there is no dedicated drug delivery catheter that can visualize the drug delivery process, deliver precise delivery, and control the delivery direction without the need for other devices. This increases the difficulty of the process and affects drug utilization. To address this, we propose a visual drug delivery catheter. Utility Model Content

[0015] To make the purpose, technical solution, and advantages of the present invention more clear, the technical solution of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0016] Please combine the following Figures 1-2 The present invention provides a technical solution: a visual drug delivery catheter, which can deliver drugs to the affected area through natural cavities (such as the esophagus, urethra, gastrointestinal tract, etc.) or artificial channels (such as tracheotomy channels, abdominal puncture, etc.).

[0017] The visual drug delivery catheter comprises a catheter body 1 and an operating end 2; the catheter body 1 is composed of a tip 3, a curved end 4 and an insertion end 5; a drug delivery channel 6 and a steel wire rope 7 are provided inside the catheter body 1; a scale 8 is provided on the outside of the catheter body; the tip 3 is provided with a drug outlet 9 and a camera assembly 10; the camera assembly 10 is composed of a lighting lamp 11 and a camera module 12; one end of the tip 3 is fixed to one end of the curved end 4, the other end of the curved end 4 is fixed to one end of the insertion end 5, the other end of the insertion end 5 is fixed to one end of the operating end 2, and the operating end 2 It is provided with a bending knob assembly 13, a drug connector 14, an air source connector 15 and a camera assembly connector 16. The bending knob assembly 13 is composed of a knob 17 and a rotating disk 18. The drug connector 14 is connected to the drug outlet 9 through the drug administration channel 6. One end of the steel wire rope 7 is fixed to one end of the bending end 4, and the other end of the steel wire rope 7 is fixed to the bending knob assembly 13. The camera assembly 10 is connected to the camera assembly connector 16 through a cable. The camera assembly connector 16 adopts a universal connector and can be directly connected to mobile phones, tablets, computers, etc. to realize video data transmission.

[0018] The steel wire rope 7 is outside the drug administration channel 6 , and the steel wire rope and the steel wire rope are parallel in the catheter body 1 .

[0019] The steel wire ropes 7 are placed inside the bent end 4 , and the number thereof is a multiple of 2.

[0020] The knob 17 can be turned by hand to drive the rotating disk 18 to rotate, and the rotation of the rotating disk 18 can drive the wire rope 7 to be pulled, and the pulling of the wire rope 7 can drive the bending end 4 to bend, with a bending angle of -275° to 275°.

[0021] One end of the drug administration channel 6 is fixed to the drug outlet 9 , and the other end of the drug administration channel 6 is connected to the drug connector 14 and the gas source connector 15 via a tee 19 .

[0022] The gas source connector is provided with a pressure regulating port 20, and the positive pressure is adjusted according to the opening size of the pressure regulating port.

[0023] The curved end is more bendable than the insertion end, and the curved end is made of a more bendable process or a softer material or is provided with a curved snake bone. When the knob 17 is turned, the curved end 4 will bend accordingly to achieve the effect of controlling the direction of the tip 3.

[0024] In actual use, the drug connector 14 is connected to the medicine bottle, and the air source connector 15 is connected to the positive pressure air source. When the camera assembly connector 16 is connected to a mobile phone or tablet, visualization is achieved through its screen. When the pressure regulating port 20 is closed, the medicine in the medicine bottle is sprayed out from the medicine outlet 9 through the drug delivery channel 6. The operator adjusts the direction of the drug delivery catheter tip 3 according to the location of the affected area by turning the knob 17, so that the drug delivery catheter can independently control the delivery direction and achieve the purpose of precise drug delivery. When the pressure regulating port 20 is opened, the positive pressure air source airflow is discharged from the pressure regulating port 20. As the opening size of the pressure regulating port 20 gradually decreases, the amount of medicine in the medicine bottle sprayed out from the medicine outlet 9 through the drug delivery channel 6 gradually increases.
