Problems solved by technology

When the existing gastric tube is used clinically, there are still some problems: (1), when the nutrient solution delivered has a large viscosity or a large particle size, the internal pipeline of the gastric tube is easily blocked and difficult to clean; (2), the current The surface of the gastric tube is coated with a developing layer, and the developing coating may seep out, causing a certain safety hazard to the human body; (3), the end of the existing gastric tube is light, without gravity guidance, and it is difficult for doctors to intubate. Low speed, high patient discomfort

specific Embodiment 1

[0038] Such as Figure 1~4 As shown, this specific embodiment discloses a more preferred embodiment of the open-close gastric tube of the present invention, including a catheter body 1, which is provided with a main channel 2 and a plurality of side through holes 3, the main channel 2 is arranged along the axial direction of the catheter body 1, and the main channel 2 is coaxially arranged with the catheter body 1, and the first end of the main channel 2 (i.e. figure 1 The left end of the main channel 2 shown in ) and the second end (ie figure 1 The right end of the main channel 2 shown in ) is open, a plurality of side through holes 3 are located on the side wall of the catheter body 1 and symmetrically arranged on both sides of the main channel 2, and the side through holes 3 penetrate the side wall of the catheter body 1 , the side through holes 3 are used to communicate with the main channel 2 and the external environment, a plurality of side through holes 3 and the side ...

specific Embodiment 2

[0056] This specific embodiment discloses another specific embodiment of an open-and-close gastric tube of the present invention. The specific arrangement of the balloon is different.

[0057] Such as Figure 5 , 6 As mentioned above, in this embodiment, only one side channel 4 and expandable balloon 5 are provided, and the expandable balloon 5 is located in the main channel 2. When the expandable balloon 5 is in a fully inflated state, it can The inflatable balloon 5 is inflated in the main channel 2 and blocks the opening of the second end of the main channel 2. When the expandable balloon 5 is not inflated or not fully inflated, the opening of the second end of the main channel 2 remains open.

[0058] Moreover, it should be noted that when the expandable balloon 5 in this embodiment is in an inflated state, it will not block the side through hole 3 on the catheter body 1 .

[0059] Of course, in addition to the setting methods in the specific embodiments 1 and 2, the st...

specific Embodiment 3

[0060] This specific embodiment discloses the use method of an open-close gastric tube disclosed in specific embodiment 1. Before use, inject inflation medium into the expandable balloon through the side channel, and the expandable balloon is fully inflated and seals the main tube. An opening at the second end of the channel. Moreover, the injected expansion medium is liquid, the expansion medium fully expands the two sub-balloons, and the expansion medium fills the two sub-channels. When operating in this way, the gastric tube can be guided by the detection device during the process of inserting the gastric tube into the human body, thereby improving the intubation efficiency and reducing the patient's discomfort.

Abstract

The invention discloses an opening and closing type stomach tube and a use method thereof. The opening and closing type stomach tube comprises a catheter body, and the catheter body is provided with amain channel, a side channel, an expandable balloon and a plurality of side through holes; the main channel and the side channel are formed in the axial direction of the catheter body, both ends of the main channel are open, and both ends of the side channel are open; the side through holes run through the side wall of the catheter body and make the main channel communicated with the external environment; the expandable balloon is arranged at the second end of the catheter body and communicated with the side channel; an expansion medium is injected into the expandable balloon through the sidechannel, then the balloon can expand and seal the second end opening of the main channel, and when the balloon is not expanded or is not sufficiently expanded, the second end opening of the main channel is opened. The opening and closing type stomach tube is simple in structure, opening and closing of the stomach tube can be controlled according to needs, cleaning of the stomach tube is facilitated, and the blockage problem is effectively solved; besides, the speed of intubation can be effectively increased, and the pain of patients is effectively alleviated.

Description

technical field [0001] The invention relates to the technical field of gastric tube structure design, in particular to an open-close gastric tube and its application method. Background technique [0002] Gastric tube is a commonly used clinical device for gastrointestinal decompression and gastrointestinal nutrition infusion. When the existing gastric tube is used clinically, there are still some problems: (1), when the nutrient solution delivered has a large viscosity or a large particle size, the internal pipeline of the gastric tube is easily blocked and difficult to clean; (2), the current The surface of the gastric tube is coated with a developing layer, and the developing coating may seep out, causing a certain safety hazard to the human body; (3), the end of the existing gastric tube is light, without gravity guidance, and it is difficult for doctors to intubate. The speed is small, and the patient's discomfort is high. [0003] Therefore, the present application is...
