Description

Technical Field

[0001] This application relates to the technical field of medical devices, and in particular to a gastric tube designed to prevent dislodgement. Background Technology

[0002] A gastric tube is used in special circumstances to deliver necessary fluids and food to patients who cannot swallow. Gastric tubes are generally made of polyurethane or silicone; depending on the material, polyurethane and silicone tubes should be replaced monthly. They come in different sizes and lengths, and are classified as either orally or nasally gastric tubes. A gastric tube consists of the tubing, a feeding port connector, a tube clamp, and a cross-shaped cap.

[0003] When using the gastric tube, the inventors found that the rate of patient extubation was very high, especially when the patient was unconscious and was likely to pull the gastric tube out of the esophagus, which would require the gastric tube to be reinstalled and cause great inconvenience. Utility Model Content

[0004] The purpose of this application is to provide a gastric tube that is designed to prevent dislodgement, thereby securing the tube in the esophagus and making it less likely to be pulled out by the patient, thus improving the safety of gastric tube use.

[0005] The anti-dislodgement gastric tube provided in this application adopts the following technical solution:

[0006] A gastric tube designed to prevent dislodgement includes a tube body, a feeding port connector and a feeding port cap located at one end of the tube body, and a spray gate located at the other end of the tube body. An airbag assembly and a control component for controlling the opening or closing of the airbag assembly are connected to the tube body. The airbag assembly is located on the tube body near the spray gate, and the control component is located inside the tube body, with one end connected to the airbag assembly and the other end connected to the feeding port connector.

[0007] By adopting the above technical solution, an airbag assembly is installed in the part of the tube that extends into the stomach cavity. During the non-feeding stage, under the control of the control component, air is injected into the tube through a syringe, causing the airbag assembly to inflate and lock against the inner wall of the stomach cavity. This effectively secures the gastric tube in the digestive tract, preventing the patient from pulling out the tube and improving safety.

[0008] As a preferred technical solution of this application, the airbag assembly includes an annular airbag and an annular airbag seat connected to the inner ring of the annular airbag. The annular airbag seat is provided with sleeve joints on both sides and is connected to the tube body through the sleeve joints.

[0009] By adopting the above technical solution, the annular airbag is installed on the annular airbag seat, which facilitates connection with the tube body, making the annular airbag firmly installed on the tube body and not easy to fall off.

[0010] As a preferred technical solution of this application, the inner ring of the annular airbag seat is provided with a limiting ring with a triangular or trapezoidal cross-section along the circumference, and an inflation hole communicating with the annular airbag is opened on the side of the limiting ring away from the spray gate.

[0011] As a preferred technical solution of this application, the control component includes a snap-fit ​​component movably connected to the limiting ring, an adjustment component movably connected to the feeding port connector, and a linear connector connecting the snap-fit ​​component and the adjustment component. The adjustment component adjusts the position of the snap-fit ​​component and controls the opening or closing of the inner ring channel of the limiting ring.

[0012] By adopting the above technical solution, the limiting ring can lock the locking component, preventing the locking component from falling out of the spray gate and also preventing the locking component from being pulled to the feed inlet connector, so that the locking component can control the flow channel at the limiting ring and control the opening and closing of the air inlet.

[0013] As a preferred technical solution of this application, the snap-fit ​​component includes an inflation port sealing sleeve, a flow guide sleeve, and a limiting ring sealing block arranged coaxially; the inflation port sealing sleeve is configured as a conical cylinder, and its outer wall can abut against the side of the limiting ring away from the spray gate, and a linear connector is connected to the inflation port sealing sleeve; the flow guide sleeve is configured as a straight cylinder, and a flow guide hole is provided on the side wall of the end away from the inflation port sealing sleeve; the limiting ring sealing block is configured as a frustum, and its outer surface can abut against the side of the limiting ring near the spray gate.

[0014] By adopting the above technical solution, the inflation hole sealing sleeve can realize the opening and closing control of the inflation hole. The channel in the middle of the inflation hole sealing sleeve can guide the flow of food fluid. The food fluid can continue to flow through the guide hole on the guide sleeve and then enter the spray gate and flow out. The limiting ring sealing block can block the limiting ring by moving, so that the inflation hole sealing sleeve opens the inflation hole, which facilitates the inflation of the annular airbag through the inflation hole.

[0015] As a preferred technical solution of this application, the feeding port connector includes a main connector pipe coaxially connected to the pipe body and a side connector pipe connected to the side wall of the main connector pipe, an adjusting component connected to the main connector pipe, and a feeding port plug connected to the side connector pipe.

[0016] As a preferred technical solution of this application, the adjusting component includes a mounting cap connected to the end of the main connector pipe and an adjusting screw threaded onto the mounting cap. One end of the adjusting screw extends into the main connector pipe and is connected to the linear connector, and the other end of the adjusting screw is connected to the adjusting cap.

[0017] By adopting the above technical solution, when sealing the air inlet, the adjusting screw can be screwed into the tube body so that the air inlet sealing sleeve can move to contact the limiting ring. When sealing the flow channel at the limiting ring, the adjusting screw can be screwed out of the tube body so that the limiting ring sealing block can move to contact the limiting ring.

[0018] As a preferred technical solution of this application, the spray gate is configured as a valve structure.

[0019] In summary, this application includes at least one of the following beneficial technical effects:

[0020] 1. This application utilizes a balloon assembly to allow the gastric tube to be secured within the digestive tract, effectively preventing or mitigating unconscious tube removal by the patient and improving the safety of gastric tube use.

[0021] 2. The air hole sealing sleeve can control the opening and closing of the air hole. The channel in the middle of the air hole sealing sleeve can guide the flow of food fluid. The food fluid can continue to flow through the guide hole on the guide sleeve and then enter the spray gate and flow out. The limiting ring sealing block can block the limiting ring by moving, so that the air hole sealing sleeve opens the air hole, which facilitates the inflation of the annular airbag through the air hole.

[0027] The following is in conjunction with the appendix Figure 1 -Appendix Figure 4 This application will be described in further detail below.

[0028] Example: This application proposes an anti-dislodgement gastric tube, referring to... Figure 1-4 The device includes a tube body 1, a feeding port connector 2, a feeding port cap 3, a spray gate 4, an airbag assembly 5, and a control assembly 6. The feeding port connector 2 and the feeding port cap 3 are located at one end of the tube body 1, and the spray gate 4 is located at the other end. Liquid food is injected into the tube body 1 through the feeding port connector 2, and the liquid food flows out through the spray gate 4 into the patient's stomach cavity. The airbag assembly 5 is installed on the tube body 1 near the spray gate 4 and also extends into the stomach cavity. Inflation of the airbag secures the gastric tube within the stomach cavity. One end of the control assembly 6 is connected to the airbag assembly 5 and controls its inflation or deflation. The other end of the control assembly 6 is connected to the feeding port connector 2, facilitating operation by medical personnel.

[0029] The tube body 1 is made of a flexible tube, and the spray valve 4 is made of a valve structure, which can prevent the reflux of liquid food in the stomach cavity from being accidentally aspirated into the lungs by the patient, thus reducing the chance of medical accidents.

[0030] The feeding port connector 2 includes a main connector tube 21 and a side connector tube 22. The main connector tube 21 is a straight, round tube, coaxial with the tube body 1, and one end is sleeved with the end of the tube body 1. The side connector tube 22 is vertically connected to the side wall of the main connector tube 21. The side connector tube 22 and the main connector tube 21 form a T-shaped structure. In this embodiment, the side connector tube 22 can be used as an interface for injecting liquid food into the syringe, and also as an interface for inflating the syringe. The feeding port plug 3 is connected to the side connector tube 22 by a plastic connecting strip. The feeding port plug 3 can block or open the opening of the side connector tube 22, facilitating the injection of liquid food into the tube body 1 through the side connector tube 22.

[0031] Reference Figure 3 and 4 The airbag assembly 5 includes an annular airbag 51, an annular airbag seat 52, a sleeve connector 53, and a limiting ring 54. The annular airbag 51 is a plastic airbag with an inflation nozzle on its inner ring. The inner ring of the annular airbag 51 is fixedly connected to the annular airbag seat 52, and the annular airbag 51 and the annular airbag seat 52 are connected by adhesive. The inflation nozzle on the annular airbag 51 passes through the annular airbag seat 52 to the inner side of the annular airbag seat 52. The sleeve connector 53 is located at both ends of the annular airbag seat in the axial direction. The tube body 1 is sleeved and fixed on the sleeve connector 53, thereby facilitating the connection between the annular airbag seat 52 and the tube body 1. The limiting ring 54 is integrally set in the inner ring of the annular airbag seat 52 and is arranged circumferentially. The cross-section of the limiting ring 54 is triangular or trapezoidal. In this embodiment, a triangle is used. Two conical surfaces are formed on both sides of the limiting ring 54. An inflation hole 55 is opened on the side of the limiting ring 54 away from the spray gate 4, which communicates with the air nozzle of the annular airbag 51. Air is pumped into the annular airbag 51 through the inflation hole 55.

[0032] The control component 6 includes a snap-fit ​​component, an adjustment component, and a linear connector 61. In this embodiment, the linear connector 61 is made of metal wire. The snap-fit ​​component is movably connected to the limiting ring 54 and can be translated to control the opening and closing of the flow channel at the center of the limiting ring 54 and the opening and closing of the inflation hole 55. The adjustment component is movably connected to the feed inlet connector 2 to control the movement of the snap-fit ​​component and adjust its position within the tube body 1. The linear connector 61 passes through the tube body 1 and connects the snap-fit ​​component and the adjustment component.

[0033] The snap-fit ​​components include an inflation port sealing sleeve 62, a flow guide sleeve 63, and a limiting ring sealing block 64, all coaxially arranged. The inflation port sealing sleeve 62 is a tapered cylinder with a maximum outer diameter equal to the inner diameter of the pipe body 1. The central hole of the inflation port sealing sleeve 62 facilitates the passage of liquid. The outer wall of the inflation port sealing sleeve 62 can contact the side of the limiting ring 54 away from the spray gate 4, sealing the inflation port 55. A linear connector 61 is attached to the end face of the inflation port sealing sleeve 62. The flow guide sleeve 63 is a straight cylinder with an outer diameter equal to the minimum inner diameter of the limiting ring 54. The flow guide sleeve 63 is located away from the inflation port sealing block. Multiple guide holes 65 are provided on one end side wall of sleeve 62. The liquid food enters the guide sleeve 63 from the air hole sealing sleeve 62 and flows out from the guide holes 65. The limiting ring sealing block 64 is set as a frustum, with a maximum diameter smaller than the inner diameter of the tube body 1, so that the liquid food can flow around the limiting ring sealing block 64. The outer side of the limiting ring sealing block 64 is conical and can contact the side surface of the limiting ring 54 near the spray gate 4, so that the limiting ring sealing block 64 can block the downward flow channel of the liquid food.

[0034] The limiting ring 54 can lock the locking component, preventing it from falling out of the spray gate 4 and also preventing it from being pulled to the feed inlet connector 2, so that the locking component can control the flow channel at the limiting ring 54 and control the opening and closing of the air inlet 55.

[0035] The adjustment components include a mounting cap 66, an adjusting screw 67, and an adjusting cap 68. The mounting cap 66 is fixedly connected to the end of the main connector tube 21. The adjusting screw 67 is threadedly connected to the mounting cap 66 and is coaxial with the main connector tube 21. One end of the adjusting screw 67 extends into the main connector tube 21 and is fixedly connected to the linear connector 61. The other end of the adjusting screw 67 is located outside the main connector tube 21 and is connected to the adjusting cap 68. The linear connector 61 can be pulled outward by rotating the adjusting screw 67, so that the limiting ring sealing block 64 gradually seals the limiting ring 54, exposing the inflation hole 55.

[0036] The implementation principle of this application embodiment is as follows: When feeding a patient using a gastric tube, the adjusting screw 67 is rotated into the main connector tube 21 to provide sufficient space for movement within the linear connector 61. The feeding port cap 3 is opened, and liquid food is injected into the tube body 1 through the side connector tube 22 using a syringe. During the flow of the liquid food within the tube body 1, it comes into contact with the air hole sealing sleeve 62, pushing the air hole sealing sleeve 62 towards the spray gate 4 until the air hole sealing sleeve 62 contacts the limiting ring 54, simultaneously blocking the air hole 55. The liquid food then passes through the guide sleeve 53, bypasses the limiting ring sealing block 64, and flows from... The nozzle 4 enters the patient's stomach cavity; after feeding, the feeding port cap 3 blocks the side connector tube 22, and the adjusting screw 67 is rotated outward to gradually tighten the linear connector 61. The limiting ring sealing block 64 contacts the side of the limiting ring 54, and the air hole sealing sleeve 62 leaves the side of the limiting ring 54 and exposes the air hole 55. At this time, the feeding port cap 3 is opened again, and air is injected into the tube 1 through the syringe. The gas can enter the annular air bag 51 through the air hole 55, so that the annular air bag 51 is inflated and stuck on the digestive tract wall, making it difficult for the patient to pull out the gastric tube. When feeding again, the air is released first and then the patient is fed.

[0037] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
