Problems solved by technology

[0003] In the process of inserting the existing nasal feeding catheter into the stomach, it needs to be penetrated bit by bit. The end of the catheter is carried out by air pressure and other equipment to enter the body. However, when the catheter is bent, there is no corresponding device for advancing the catheter. Pushing the catheter manually with the curved catheter can not accurately control the speed, and it is easy to cause bending, resulting in the catheter not entering smoothly, laborious and laborious, and causing severe vomiting of the patient. Therefore, we propose a medical nasal feeding catheter with controllable pressure conduction at the head end. Method and device for steering

Embodiment 1

[0031] see Figure 1-Figure 2 , a device for controllable steering of pressure conduction at the head end of a medical nasogastric feeding catheter in the illustration includes a connecting assembly 2 communicated with the catheter 1; a push assembly 10 is used to push and fit the catheter 1 when the connecting assembly 2 operates. The pushing assembly 10 is arranged on the catheter 1 .

[0032] see Figure 2-Figure 3 , the connecting assembly 2 in the figure includes an expansion connecting pipe 4 and a curved connecting pipe 5 and an injection connecting pipe 6 which are distributed obliquely and communicated with the catheter 1. A controller, the curved connecting pipe 5 is used to connect to the third controller that controls the front end of the curved catheter 1, and the injection connecting pipe 6 is used to connect to the second controller that controls the injection of contrast medium.

[0033] see Figure 4 , the push assembly 10 in the figure includes a fixed pla...

Embodiment 2

[0044] see Figure 8-Figure 10 , the adjustment assembly 30 in the figure includes a fixed ball 31, a through groove 32 is formed on the fixed ball 31, a first movable groove 33 is opened on the side of the second rotating plate 16, and the first movable groove 33 is fixedly connected to the through groove 32. The matching limit post 34 is fixedly connected to the inner wall of the first movable groove 33 with a limit ring 35 which is press-fitted with the fixed ball 31 .

[0045] In this embodiment, after the angle of the third set of rods 29 changes, it drives the fixed ball 31 to rotate, the limit post 34 moves in the through groove 32 and automatically adjusts the position, the fixed ball 31 is always located in the first movable groove 33, and passes through the limit post 34 , the second rotating plate 16 is rotated along the collar 17 .

Embodiment 3

[0047] see Figure 5-Figure 7 , the flip assembly 36 in the figure includes a rotating plate 37 that is fixedly connected with the rotating rod 18, the two ends of the rotating plate 37 and the fixed plate 11 are provided with mutually adapted insertion holes 38, and the middle of the rotating plate 37 is provided with a sliding slot 39, A movable rod 40 is slidably connected in the sliding groove 39, and an end of the movable rod 40 is rotatably connected with a telescopic rod 41 that is connected and fixed with the first sleeve 21. The fixing plate 11 is provided with a second movable slot 43 , and the fixing plate 11 is also provided with two clamping slots 44 communicating with the second movable slot 43 . A rotating rod 7 is rotatably connected between the two grooves, and a tension spring 8 is hooked between the telescopic rod 41 and the rotating rod 7 .

[0048] In this embodiment, when the third controller is running, the third set of rods 29 is located on the side of...

Abstract

The invention discloses a controllable steering method and device for pressure conduction at the head end of a medical nasal feeding catheter, relates to the technical field of nasal feeding catheter control devices, and solves the problem of difficult insertion caused by different synchronization of catheter pushing and catheter bending. According to the invention, when the controller is used for bending and other operations, the guide pipe is driven to carry out adaptive pushing movement, the controller and the pushing assembly are synchronously carried out to ensure that the guide-in depth is stable and rapid, and the mode is convenient to operate, high in practicability and high in practicability. And the controllability is high.

Description

technical field [0001] The invention relates to the technical field of nasal feeding catheter control devices, in particular to a method and device for controllable steering of pressure conduction at the head end of a medical nasal feeding catheter. Background technique [0002] Nasogastric feeding is the nasogastric feeding method, which is to artificially insert the gastric tube into the esophagus through the nasal cavity under special circumstances, first grind the food with a grinder, and use a large syringe to connect the large feeding port under the gastric tube joint. After the connection is firm, manually The pressurized push rod piston fetches water and food into the patient's stomach to help patients who cannot swallow independently to provide water and food to maintain metabolism, body weight and nutrition in the body. The size of the gastric tube is thick or thin, and the thin tube is easy to block with little damage. Made of polyurethane or silicone, a gastric ...
