Embodiment

[0030] Embodiment: a kind of multipurpose gastrointestinal conformal tunnel (see attached figure 1 attached figure 2 ), including a catheter 9 made of medical polymer material, with an expandable membrane channel 7 connected to the catheter wall.

[0031] The front end of the catheter is fixed with a transparent capsule 11, the outer circumference of the transparent capsule is larger than the outer diameter of the tunnel when the tunnel is tightened, and the transparent capsule seals the front end of the catheter. A signal source device 12 of an optical system or an imaging system is arranged in the transparent capsule, and a metal wire 10 is embedded in the catheter wall, and the metal wire is connected to the signal source device, and the signal output terminal 2 is connected to the wire at the end of the catheter. Connect the signal receiving device through the output terminal to receive the signal from the signal source device. A plurality of side holes 8 are provided o...

Embodiment 2

[0037] Embodiment 2: A multi-purpose gastrointestinal conformal tunnel. The difference from Embodiment 1 is that an outlet dilator 15 is connected to the outlet end of the film channel, and the outlet dilator is an inflatable elastic body. When the outlet dilator is in a contracted state Close to the catheter wall, the outlet dilator expands and stretches the outlet end of the film channel, and the inlet dilator and the outlet dilator respectively use their own air inlet tubes. One end of the membrane channel connected to the outlet expander is the outlet 14 of the membrane channel.

[0038] Connect the valve of the intake pipe, control the inlet dilator 6 from the outside to expand and stretch the entrance 17 of the film channel, and control the outlet expander to expand and stretch the outlet 14 of the film channel at the same time (see attached image 3 ). Refer to Example 1 for all the other structures.

Embodiment 3

[0039] Embodiment 3: A multi-purpose gastrointestinal conformal tunnel, the difference from Embodiment 2 is that several intermediate dilators 16 are connected to the middle part of the membrane channel, and the intermediate dilator is a ring structure, and the intermediate dilator and Inlet dilator and outlet dilator share the same inlet tube (see attached Figure 4 ).

[0040] The membrane channel enters the gastrointestinal cavity, and when the connection valve is inflated, it is subjected to the pressure of the gastrointestinal wall. Under the same pressure, the membrane channel forms a shape suitable for the gastrointestinal cavity, and the membrane channel fits the gastrointestinal wall. Refer to Implementation 2 for other structures.

Abstract

A multipurpose gastrointestinal conformal tunnel, comprising a hollow catheter (9) for guiding when inserted into a gastrointestinal tract. An expandable membrane channel (7) is connected to the catheter (9); the end of the membrane channel (7) toward the insertion end of the catheter (9) is fixed to the catheter (9) and is provided with at least one outlet (14); and the end of the membrane channel (7) toward the trailing end of the catheter (9) is fixed to the catheter (9) via an inlet expander (6), the end forming a membrane channel inlet (17). The inlet expander (6) is an inflatable elastomer or memory alloy; in the contracted state, the inlet expander (6) is in very close proximity to the wall of the catheter (9), and after expansion, expands the membrane channel (7) to form an inlet (17). After the membrane channel (7) is inserted into a gastrointestinal tract along with the catheter (9), the inlet expander (6) expands the inlet (17) of the membrane channel (17), and fixes the inlet expander (6) in a proper position so that the masticated food from the oral cavity can come into the inlet (17) and out of the outlet (14) of the membrane channel (7).

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a multipurpose gastrointestinal conformal tunnel and an operation method. Background technique [0002] There are many types of nutrition tubes, drainage tubes, drug delivery tubes, and compression hemostasis that can be inserted into the gastrointestinal tract produced and sold at home and abroad, with different functions. Although various pipelines have their own characteristic advantages and scope of application, there are also some common deficiencies. The outer diameter of various pipes is mostly 5-7mm, and the inner diameter is rarely more than 5mm. As an enteral nutrition pipe, it can only be dripped with special and expensive clear and thin juice nutrient solution, which is prone to blockage. [0003] Although some nutrition tubes have other functions, for example, they can be equipped with oxygen delivery tubes at the same time, or have the drainage effect of sucking blee...
