Description

Technical Field

[0001] This utility model belongs to the field of gastric tube technology, specifically relating to an air-filled anti-dislodgement gastric tube. Background Technology

[0002] The working principle of a balloon-type gastric tube mainly relies on the inflation and deflation of the balloon. When the balloon is inflated, it expands and fits tightly against the patient's esophagus or stomach, thereby securing the gastric tube and preventing it from falling out. At the same time, the food outlet on the gastric tube allows food or medication to smoothly enter the patient's stomach.

[0003] Currently, when using balloon-type gastric tubes, the addition of a balloon at the bottom and an air inlet tube connected above the balloon increases the diameter of the tube. This may result in greater resistance during insertion, leading to a longer insertion time and potentially damaging the patient's esophagus or gastric mucosa.

[0004] Therefore, in order to address the above-mentioned technical problems, it is necessary to provide a balloon-type anti-dislodgement gastric tube.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0006] The purpose of this invention is to provide an air-filled anti-dislodgement gastric tube that can solve the problems mentioned in the background art.

[0007] To achieve the above objectives, a specific embodiment of this utility model provides the following technical solution: a balloon-type anti-dislodgement gastric tube, comprising a gastric tube, an air inlet tube being snapped onto one side of the outer wall of the gastric tube, the bottom end of the air inlet tube being connected to an air balloon body matching the gastric tube, the inner wall of the air balloon body being snapped onto the bottom outer wall of the gastric tube, and the outer end faces of the air inlet tube and the air balloon body in the initial state not protruding from the outer end face of the gastric tube.

[0008] In one or more embodiments of this utility model, the gastric tube includes an inlet tube, a groove matching the air inlet tube is provided on one side wall of the inlet tube, and an annular groove matching the airbag body is provided on the outer wall of the bottom end of the inlet tube.

[0009] In one or more embodiments of the present invention, the airbag body includes an elastic airbag, the inner wall of which is attached to the outer wall of the annular groove.

[0010] In one or more embodiments of this utility model, the feeding tube has a slot at the bottom end face of the groove.

[0011] In one or more embodiments of this utility model, the air intake pipe includes an air intake pipe, and the bottom end face of the air intake pipe is integrally formed with a locking post that matches the locking groove, and the outer wall of the locking post is engaged with the inner wall of the locking groove.

[0012] In one or more embodiments of this utility model, an auxiliary head is installed on the top end face of both the feeding tube and the air inlet tube.

[0013] In one or more embodiments of this utility model, a first connection hole is provided on the bottom end face of the air intake pipe.

[0014] In one or more embodiments of this utility model, a second connecting hole matching the first connecting hole is provided on the bottom outer wall of the elastic airbag, and the first connecting hole and the second connecting hole are bonded to each other.

[0015] In one or more embodiments of this utility model, the auxiliary head includes a feeding tube interface, and a control valve is installed at one end of the air inlet pipe near the feeding tube interface.

[0016] In one or more embodiments of this utility model, a sealing cap is snapped onto one side wall of the feeding tube interface.

[0017] Compared with the prior art, the present invention provides a balloon-type anti-dislodgement gastric tube in which the air inlet tube and the balloon on one side of the gastric tube are both locked inside the gastric tube. Therefore, the air inlet tube and the balloon body do not protrude from the outer diameter of the gastric tube, resulting in a compact structure.

Detailed Implementation

[0027] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0028] like Figures 1-2 As shown, an embodiment of the present invention provides a balloon-type anti-dislodgement gastric tube, comprising a gastric tube 1, an air inlet tube 2 attached to one outer wall of the gastric tube 1, and a balloon body 3 matching the gastric tube 1 connected to the bottom end of the air inlet tube 2. The inner wall of the balloon body 3 is attached to the outer wall of the bottom end of the gastric tube 1. When the gastric tube enters the human body, since both the air inlet tube 2 and the balloon body 3 are attached inside the gastric tube 1, the outer end faces of the air inlet tube 2 and the balloon body 3 are not protruding from the outer end face of the gastric tube 1 in the initial state. In the initial state, when no air enters the air inlet tube 2, the volume of the balloon body does not expand due to the gas. This balloon-type anti-dislodgement gastric tube has the same external shape and thickness as a normal single gastric tube. When entering the human body, the efficiency of intubation will not be affected by the addition of the air inlet tube and the balloon, thus avoiding greater damage to the human body.

[0029] Furthermore, auxiliary heads 4 are installed on the top end faces of both the feeding tube 101 and the air inlet tube 201. The auxiliary head 4 includes a feeding tube interface 401, and a sealing cap 402 is snapped onto one side wall of the feeding tube interface 401. The staff inputs liquid food and gas into the feeding tube 101 and the air inlet tube 201 respectively through the feeding tube interface 401 installed at the top of the feeding tube 101 and the air inlet tube 201. After the delivery is completed, the sealing cap 402 is snapped onto the opening of the feeding tube interface 401, so that the inside of the feeding tube interface 401 forms a closed space to prevent bacteria from entering the inner wall of the gastric tube and causing harm to the human body.

[0030] Furthermore, a control valve 5 is installed at one end of the air inlet pipe 201 near the feeding tube interface 401. After air is introduced, the gas is sealed in the air bladder to prevent backflow and leakage, which could cause the air bladder to collapse and the trachea to move inside the stomach, thereby irritating the stomach.

[0031] like Figure 6 As shown, the gastric tube 1 includes an inlet tube 101. A groove 102 matching the air inlet tube 2 is provided on one side wall of the inlet tube 101. The groove 102 is designed with an arc shape, so that the air inlet tube 2 is stably attached to the inner wall of the groove 102, which is not easy to fall off, and at the same time, it is easy to disassemble and clean.

[0032] Furthermore, an annular groove 103 matching the airbag body 3 is provided on the outer wall of the bottom end of the feeding tube 101. The annular groove 103 is designed with an arc shape, so that the airbag body 3 is stably fixed on the outer wall of the annular groove 103, avoiding sliding on the outer wall of the feeding tube 101. After the airbag body 3 is inflated, it can be stably locked at the cardia, so that the gastric tube is fixed in a suitable position, which can prevent it from moving up and down and also prevent the reflux of gastric contents.

[0033] like Figures 3-6 As shown, the feeding tube 101 has a slot 104 at the bottom end face of the groove 102. The air inlet tube 2 includes an air inlet tube 201. The bottom end face of the air inlet tube 201 is integrally formed with a locking post 202 that matches the slot 104. The outer wall of the locking post 202 is engaged with the inner wall of the slot 104, so that the bottom end of the air inlet tube 2 is engaged with the bottom end face of the slot 104, preventing the air inlet tube 201 from sliding on the inner wall of the groove 102, thereby enhancing the stability of the air inlet tube 2 and the air bag body 3 on the gastric tube 1.

[0034] Furthermore, a first connecting hole 203 is provided on the bottom end face of the air intake pipe 201, and a second connecting hole 302 matching the first connecting hole 203 is provided on the bottom outer wall of the elastic airbag 301. The first connecting hole 203 and the second connecting hole 302 are bonded to each other. The interiors of the air intake pipe 201 and the elastic airbag 301 are connected. Gas is transported into the elastic airbag 301 through the air intake pipe 201. Subsequently, the elastic airbag 301 expands and is locked at the cardia of the stomach.

[0035] Furthermore, the airbag is made of natural latex, a natural polymer material with good elasticity and flexibility. Staff can adjust the volume of the inflated elastic airbag 301 according to the size of the patient's stomach and the specific circumstances of use, based on the amount of air intake.

[0036] When using, such as Figure 2 As shown, the air inlet tube 2 is inserted into the gastric tube 1. In the initial state (no air intake state), the airbag body 3 is located inside the gastric tube 1. The operator first slowly inserts the bottom end of the gastric tube 1 into the esophagus through the mouth or nose. The bottom end of the gastric tube 1 has a rounded structure, which can effectively reduce the stimulation of the gastric tube to the esophagus; Figure 1 As shown, when the balloon body 3 enters below the cardia of the stomach, the control valve 5 is opened, and gas is transmitted into the balloon body 3 through the auxiliary head 4 and the air inlet tube 2. When the balloon body 3 inflates to just fit at the cardia, the air intake stops, and the control valve 5 is closed to prevent gas leakage, thereby fixing the gastric tube 1 stably in the patient's stomach, thus fixing the gastric tube and preventing it from falling out. When disassembling and cleaning the gastric tube, pull the side of the air inlet tube 201 away from the esophagus 101, so that the air inlet tube 201 is away from the groove 102. Then lift the air inlet tube 201 upward, so that the locking post 202 is away from the locking groove 104. Then pull the balloon 3, so that the balloon 3 comes out from the bottom of the gastric tube 1, thereby moving the balloon tube 2 and the balloon 3 away from the side of the gastric tube 1, which facilitates the subsequent cleaning work.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
