Description

Technical Field

[0001] The present invention relates to the technical field of medical auxiliary equipment, and in particular to an IOE gastric tube insertion auxiliary device. Background Art

[0002] IOE gastric tube refers to the feeding tube used in intermittent oral to esophageal tube feeding. IOE technology is a method of treating dysphagia. This technology replaces nasogastric feeding. When the patient needs to eat, the gastric tube is inserted into the esophagus through the mouth. After eating, the IOE gastric tube can be removed. This technology can stimulate the posterior pharyngeal wall and induce swallowing reflex during the intubation operation, avoiding problems such as esophageal reflux and aspiration pneumonia caused by the indwelling gastric tube, providing a transition period for clinical treatment. Early IOE is conducive to the recovery of swallowing function as soon as possible. It also conforms to the physiological law of oral feeding, has no nasal stimulation, avoids throat spasm, and is more humane. In actual use, during or after the insertion of the IOE gastric tube through the mouth, the patient is prone to biting the gastric tube, affecting the insertion and subsequent eating. The patient will be more tired if he keeps his mouth open. In addition, when inserting the gastric tube, there is a lack of structure to judge whether the gastric tube is inserted into the stomach, and the insertion of the gastric tube into the patient's trachea poses a safety hazard.

[0003] In order to solve the above problems, we propose an IOE gastric tube insertion auxiliary device, which can support the patient's mouth to facilitate the insertion of the gastric tube for eating, and can also detect and ensure that the gastric tube is inserted into the patient's stomach.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Embodiment 1: An IOE gastric tube insertion auxiliary device, such as Figure 1-Figure 8As shown, it includes a fixed frame 1, a mouth pad 2, a guide tube 3, a liquid cylinder 4, a liquid discharge ball 5, a connecting block 6, an oil cylinder 7, a detection mechanism and an extrusion mechanism. The fixed frame 1 is fixedly connected with the guide tube 3, the guide tube 3 is fixedly connected with the mouth pad 2, the upper and lower sides of the mouth pad 2 are provided with rubber gaskets, the right side of the guide tube 3 is fixedly connected with the liquid cylinder 4, the upper side of the liquid cylinder 4 is connected with a detachable plug for adding vinegar liquid, four circumferentially equidistantly distributed liquid discharge balls 5 are rotatably connected in the liquid cylinder 4, four equidistantly distributed connecting blocks 6 are fixedly connected to the right side of the liquid cylinder 4, the oil cylinder 7 is fixedly connected between the four connecting blocks 6, and the inner side of the oil cylinder 7 is provided with equidistantly distributed oil outlets, the fixed frame 1 is provided with a detection mechanism for detecting whether the gastric tube is inserted into the stomach, and the fixed frame 1 is provided with an extrusion mechanism for squeezing the liquid discharge ball 5 to rotate and drip the vinegar liquid.

[0035] When using the device, the patient bites the mouth pad 2, and the mouth pad 2 supports the patient's oral cavity, so that the patient keeps his mouth open, and the patient is prevented from biting the gastric tube to affect the insertion and subsequent eating. Under the action of the rubber gasket, the comfort of the patient's bite can be improved. At this time, the staff can control one end of the gastric tube to be inserted into the left side of the guide tube 3, and guide and control the gastric tube to enter the patient's oral cavity through the guide tube 3. When the gastric tube moves to the right, the paraffin oil in the oil cylinder 7 can be applied to the surface of the gastric tube for lubrication, thereby reducing the friction and damage to the nasal cavity, throat and esophageal mucosa when the gastric tube is inserted, so that the gastric tube can pass through these parts more smoothly and comfortably into the stomach. When the gastric tube reaches the throat, the staff can control the rotation of the liquid outlet ball 5 through the squeezing component, and then drip a small amount of vinegar liquid, and use the vinegar liquid to stimulate the patient to swallow, so as to help guide the gastric tube to pass through the throat smoothly into the stomach. When the gastric tube is inserted, the staff can connect the tail end of the gastric tube with the detection mechanism, and use the detection mechanism to detect whether the gastric tube is inserted into the stomach position.

[0036] like Figure 1 and Figure 5 As shown, the detection mechanism includes a mounting frame 8, a test cylinder 81, a docking tube 9, a one-way valve 10 and an exhaust pipe 11. The mounting frame 8 is fixedly connected to the upper right side of the fixing frame 1, and the test cylinder 81 is fixedly connected to the upper part of the mounting frame 8. The test cylinder 81 is filled with water, and a transparent observation window is provided on the test cylinder 81. The lower side of the test cylinder 81 is connected to the docking tube 9, and the one-way valve 10 is installed on the docking tube 9. The rear side of the test cylinder 81 is connected to the exhaust pipe 11.

[0037] When the gastric tube is inserted, the staff controls the tail end of the gastric tube to dock with the docking tube 9, and then squeezes the gastric tube. If air in the gastric tube enters the docking tube 9, bubbles will appear in the water of the test tube 81. If no bubbles appear, it means that the gastric tube is not inserted into the trachea by mistake, but is located in the stomach. The staff can know whether the gastric tube is inserted in place by observing the bubbles inside the test tube 81 through the observation window. During the inspection, under the action of the one-way valve 10, the liquid in the test tube 81 can be prevented from entering the gastric tube through the docking tube 9. After the inspection is completed, the air in the test tube 81 can also be discharged through the exhaust pipe 11 for subsequent inspection.

[0038] like Figure 1 , Figure 6 , Figure 7 and Figure 8 As shown, the extrusion mechanism includes a sliding frame 12, an extrusion rod 13, a disc 14 and a first torsion spring 15. The sliding frame 12 is slidable on the fixed frame 1, and the sliding frame 12 extends into the guide tube 3. Four equidistantly distributed extrusion rods 13 are fixedly connected to the sliding frame 12. The liquid outlet ball 5 is fixedly connected to a disc 14, and the discs 14 are each provided with an inclined sheet. The extrusion rod 13 is extruded and matched with the adjacent inclined sheets, and a first torsion spring 15 is connected between the disc 14 and the liquid-filling cylinder 4.

[0039] When the gastric tube reaches the patient's throat, the staff pushes the sliding frame 12 to slide to the right. The sliding frame 12 slides to the right and drives the squeezing rod 13 to move to the right. After the squeezing rod 13 moves to the right, it squeezes the inclined piece on the disc 14, thereby controlling the rotation of the disc 14. The first torsion spring 15 is deformed, and the rotation of the disc 14 drives the liquid outlet ball 5 to rotate and open, and the vinegar in the liquid cylinder 4 can drip out through the liquid outlet ball 5. Then the staff releases the sliding frame 12. Under the action of the first torsion spring 15 resetting, the disc 14 reverses and drives the liquid outlet ball 5 to reverse and close. The reversal of the disc 14 will also push the squeezing rod 13 and the sliding frame 12 to slide to the left and reset through the inclined piece.

[0040] Embodiment 2: Based on embodiment 1, Figure 1 , Fig. 9 , Fig.10 , Fig.11 , Fig.12 , Fig.13 and Fig.14As shown, it also includes a pushing mechanism for uniformly pushing the gastric tube into the patient's oral cavity, the pushing mechanism includes an electric push rod 16, a connecting rod 17, a fixed ring 18, a rotating ring 19, a first cylinder 20, a connecting ring 201, a second cylinder 21, an extrusion frame 22, an extrusion block 23, a clamp 24 and a second torsion spring 25, the front side of the fixing frame 1 is fixedly connected to the electric push rod 16, the front and rear parts of the fixing frame 1 are both slidably connected to the connecting rod 17, the front connecting rod 17 is connected to the telescopic end of the electric push rod 16, the front and rear connecting rods 17 are fixedly connected to the fixing ring 18, the rotating ring 19 is rotatably connected to the fixing ring 18, and the first cylinder 20 is fixedly connected to the right side of the fixing ring 18. Cylinder 20, a connecting ring 201 is fixedly connected to the right side of the first cylinder 20, and a second cylinder 21 is movably connected inside the connecting ring 201, and mutually matching protrusions and grooves are provided on the side where the first cylinder 20 and the second cylinder 21 are close to each other, an extrusion frame 22 is fixedly connected to the right side of the fixed frame 1, a spiral groove is opened on the rotating ring 19, and the extrusion frame 22 is extruded and matched with the rotating ring 19 through the spiral groove, and three circumferentially equidistantly distributed extrusion blocks 23 are fixedly connected to the inner side of the rotating ring 19, and three circumferentially equidistantly distributed clamps 24 are rotatably connected to the right side of the fixed ring 18, and the extrusion blocks 23 are extruded and matched with adjacent clamps 24, and a second torsion spring 25 is connected between the clamps 24 and the fixed ring 18.

[0041] like Fig.15 As shown, it also includes a closing mechanism for automatically controlling the liquid-discharging ball 5 to reset and stop discharging liquid. The closing mechanism includes a cross bar 26 and a protrusion 27. Four cross bars 26 equidistantly distributed circumferentially are fixedly connected to the right side of the rotating ring 19, and four protrusions 27 equidistantly distributed circumferentially are fixedly connected to the left part of the second cylinder 21. The cross bar 26 is squeezed and matched with the adjacent protrusions 27.

[0042] By setting a pushing mechanism and a closing mechanism, the gastric tube can be automatically and uniformly pushed to the patient's throat, and then a certain amount of vinegar can be controlled to drip out, which reduces the operation of medical staff and is more convenient to use. The specific operation is as follows: the staff controls the rotating ring 19 to rotate, and the rotating ring 19 rotates to squeeze the clamping plate 24 through the squeezing block 23 to rotate and open, and the second torsion spring 25 is deformed. Then the staff inserts the gastric tube into the fixing ring 18, controls the gastric tube to pass through the first cylinder 20, the second cylinder 21 and the guide tube 3, and moves the gastric tube to the liquid cylinder 4 and the oil cylinder 7, and then the staff The double-open rotating ring 19, under the action of the second torsion spring 25 resetting, the splint 24 reverses and clamps the gastric tube, and the splint 24 reverses and drives the rotating ring 19 to reverse and reset through the extrusion block 23. After the gastric tube is fixed, the staff controls the connecting rod 17 to move right through the electric push rod 16, and the connecting rod 17 moves right to drive the fixing ring 18 to move right. The fixing ring 18 moves right to drive the gastric tube to move right slowly and uniformly through the splint 24. When the fixing ring 18 moves right, it also drives the rotating ring 19, the first cylinder 20, the connecting ring 201 and the second cylinder 21 to move right. When the second cylinder 21 moves to the right until it contacts the right part of the sliding frame 12, the second cylinder 21 pushes the sliding frame 12 to slide to the right, and then the liquid-discharging ball 5 is driven to open and drip vinegar liquid through the squeezing cooperation between the squeezing rod 13 and the disc 14, and when the rotating ring 19 moves to the right until it contacts the squeezing frame 22, the rotating ring 19 continues to move to the right and is squeezed and rotated by the squeezing frame 22. After the rotating ring 19 rotates, the control clamp 24 releases the stomach tube. When the rotating ring 19 rotates, it also drives the cross bar 26 to rotate. The cross bar 26 rotates to squeeze the protrusion 27, so that the second cylinder 21 moves to the right until it contacts the right part of the sliding frame 12. The cylinder 21 rotates, and after the second cylinder 21 rotates, the groove on the second cylinder 21 corresponds to the protrusion on the first cylinder 20. At this time, the first cylinder 20 cannot squeeze the second cylinder 21 and the sliding frame 12, and the liquid outlet ball 5 is reversed and closed, thereby pushing the squeezing rod 13, the sliding frame 12 and the second cylinder 21 to slide to the left. In this way, the gastric tube can be automatically controlled to move slowly and evenly to the patient's throat. At the same time, when the gastric tube moves to the patient's throat, the liquid outlet ball 5 can be automatically controlled to drip a certain amount of vinegar and then close, which reduces the operation of medical staff and is more convenient to use.

The description of the above embodiments is only used to help understand the method of the present application and its core idea. At the same time, for general technical personnel in this field, according to the idea of ​​the present application, there will be changes in the specific implementation methods and application scope.
