Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an orally indwelling gastric tube fixator. Background Technique

[0002] There are many patients in bed who cannot have a gastric tube inserted through the nasal cavity: commonly seen in patients with nasal septum deviation, patients undergoing nasal surgery, patients with nasal trauma, patients undergoing resection of sellar tumors through the nose, etc. All of them need to use an orally indwelling gastric tube, and it is relatively difficult to fix the orally indwelling gastric tube and it is easy to get the tube out.

[0003] When the patient's condition improves, the intubation needs to be removed. When removing the intubation, it is very easy to drive the indwelling gastric tube out together. Medical staff need to reinsert the indwelling gastric tube, causing secondary harm to the patient and increasing the workload of medical staff.

The indwelling gastric tube 3 is inserted into the rubber plate 1 and is fixedly connected thereto. A cushion layer 14 is fixedly installed on one side of the rubber plate 1. Two fixing blocks 5 are fixedly installed on the side of the rubber plate 1 away from the cushion layer 14. Two arc-shaped plates 6 are arranged between the two fixing blocks 5. On the corresponding two sides of the two arc-shaped plates 6, sliders 7 are fixedly installed respectively. A plurality of sliders 7 are respectively inserted into the two arc-shaped plates 6 and are slidably connected thereto. An airbag 4 is fixedly installed on the outer side of the indwelling gastric tube 3. On the side of the airbag 4 close to the rubber plate 1 and on the corresponding two sides of the indwelling gastric tube 3, fixing plates 29 are fixedly installed respectively. Both fixing plates 29 are fixedly connected to the rubber plate 1.

[0021] One of the fixed blocks 5 is internally rotatably connected with a first worm gear 10 and a first worm 11. The first worm gear 10 and the first worm 11 are meshed. One side of the first worm gear 10 is fixedly installed with a bidirectional lead screw 9. The bidirectional lead screw 9 is rotatably connected with one of the fixed blocks 5. The bidirectional lead screw 9 passes through the sliders 7 on one side of the two arc-shaped plates 6 and is threadedly connected with them. The top of the first worm 11 is fixedly installed with a first turning handle 12. The first turning handle 12 passes through the top of one of the fixed blocks 5 and is rotatably connected with it. By rotating the first turning handle 12, the first worm 11 drives the first worm gear 10 to rotate, so that the two sliders 7 on the outer side of the bidirectional lead screw 9 drive the two arc-shaped plates 6 to approach each other, so as to fix the position of the intubation tube 2 through the arranged arc-shaped plates 6. A guide rod 8 is fixedly installed inside the other arc-shaped plate 6. The guide rod 8 passes through the sliders 7 on the other side of the two arc-shaped plates 6 and is slidably connected with them. Rubber pads 13 are fixedly installed on one side of the two arc-shaped plates 6 where they approach each other. The arranged guide rod 8 makes the arc-shaped plates 6 more stable during lateral movement, further improving the stability of clamping the intubation tube 2.

[0022] An air cavity 15 is formed in the rubber plate 1. A push plate 16 is slidably connected inside the air cavity 15. A fixed cylinder 19 is rotatably connected inside the rubber plate 1. The fixed cylinder 19 is inserted into the air cavity 15 and is rotatably connected with it. A fixed rod 17 is arranged on one side of the fixed cylinder 19 close to the air cavity 15. A limiting plate 18 is fixedly installed on one side of the fixed rod 17. The fixed rod 17 is inserted into the push plate 16 and is rotatably connected with it. The limiting plate 18 is rotatably connected with the push plate 16. The fixed rod 17 is inserted into the fixed cylinder 19 and is threadedly connected with it. A second worm gear 20 and a second worm 21 are rotatably connected inside the rubber plate 1. The second worm gear 20 and the second worm 21 are meshed. The second worm gear 20 is fixedly connected with the fixed cylinder 19. A second turning handle 22 is fixedly installed on one side of the second worm 21. The second turning handle 22 passes through one side of the rubber plate 1 and is rotatably connected with it. A connecting pipe 23 is arranged on one side of the air cavity 15. The connecting pipe 23 is inserted into the air cavity 15 and is communicated with it. The connecting pipe 23 is inserted into the airbag 4 and is communicated with it. By rotating the second turning handle 22, the second worm 21 drives the second worm gear 20 to rotate, so that the fixed rod 17 moves out of the fixed cylinder 19, so that the arranged push plate 16 pushes the gas inside the air cavity 15, and the gas is conveyed into the airbag 4 through the connecting pipe 23. Further, the volume of the arranged airbag 4 contacts the patient's oral cavity, reducing the possibility of the device falling off.

[0023] On one side of the rubber plate 1 and on the corresponding two sides of the cushion layer 14, two first fixing belts 25 and second fixing belts 26 are respectively and fixedly installed. On the outer sides of the two first fixing belts 25, hook-and-loop fasteners with a fuzzy surface 27 are inlaid. On one side of the two second fixing belts 26 close to the first fixing belts 25, hook-and-loop fasteners with a hook surface 28 are inlaid. Through the cooperation of the two first fixing belts 25 and the second fixing belts 26 provided, the fixation of the device to the patient is realized, and the stability of the device during use is improved. A plurality of ventilation holes 24 are formed in the rubber plate 1, and grooves are formed on one side of the rubber plate 1 and the cushion layer 14. Through the cushion layer 14 and the ventilation holes 24 provided, the comfort of the patient when using the device is improved.

[0024] In summary, when using this orogastric tube fixator, the airbag 4 of the device is placed in the patient's mouth, and the indwelling gastric tube 3 fixedly connected to one side thereof is inserted into the patient's stomach to realize the placement of the device. The intubation tube 2 and the indwelling gastric tube 3 are inserted into the indwelling gastric tube 3 for connection. Further, by rotating the first rotating handle 12, the first worm 11 drives the first worm gear 10 to rotate, so that the two sliders 7 on the outer side of the bidirectional lead screw 9 drive the two arc-shaped plates 6 to approach each other, and the position of the intubation tube 2 is fixed by the arc-shaped plates 6 provided, preventing the indwelling gastric tube 3 from moving when the intubation tube 2 is separated from the indwelling gastric tube 3 and the intubation tube 2 is acted on, thereby reducing the possibility of affecting the patient. At the same time, by adjusting the distance between the two arc-shaped plates 6, the clamping and fixed connection of intubation tubes 2 of more sizes can be realized, and the applicability of the device is improved.

[0025] When using the device, by rotating the second rotating handle 22, the second worm 21 drives the second worm gear 20 to rotate, so that the fixing rod 17 moves out of the fixing cylinder 19, and the gas in the air chamber 15 is pushed by the push plate 16 provided, and the gas is conveyed into the airbag 4 through the connecting pipe 23. Further, the volume of the airbag 4 contacts the patient's oral cavity, reducing the possibility of the device falling off. Further, through the cooperation of the fixing plate 29 and the airbag 4 provided, the possibility of the indwelling gastric tube 3 in the patient's oral cavity contacting the teeth and causing wear is prevented, and the service life of the device is improved. At the same time, a sealing ring is provided at the junction of the rubber plate 1 and the fixing cylinder 19, thereby improving the sealing effect of the device.
