Description

Technical Field

[0001] The utility model relates to the technical field of nasogastric feeding tube fixing, in particular to a nasogastric feeding tube fixing structure. Background Art

[0002] A nasogastric tube is a medical device used to deliver nutrients or medicines into the patient's stomach through the nasal cavity. During the use of a nasogastric tube, it should be ensured that the tube is stably fixed in the patient's nostrils to avoid displacement or falling off.

[0003] In the prior art, a transparent adhesive tape or a medical adhesive tape is generally used to fix the nasogastric feeding tube on the facial skin of the patient to ensure that the feeding tube is firmly attached to the skin around the nostrils.

[0030] Embodiment 1:

[0031] See also Figures 1 to 3 In an embodiment of the utility model, a nasogastric tube fixing structure includes a pad 3 for contacting the philtrum of a patient, both ends of the pad 3 are fixedly connected with elastic bands 1, and an ear hook 2 is fixedly installed at one end of the elastic band 1 away from the philtrum;

[0032] A fixing mechanism 4 is fixedly installed on the front of the backing plate 3. The fixing mechanism 4 includes an adjusting component 5 fixedly installed on the front of the backing plate 3. A fixing component 6 is arranged in the adjusting component 5. The adjusting component 5 is used to adjust the position between the fixing component 6 and the nostril.

[0034] The adjustment assembly 5 includes a first connecting seat 8, and the front side of the pad 3 is fixedly mounted with the first connecting seat 8 near both ends thereof, and two guide rods 9 symmetrically arranged about the length midline of the pad 3 are fixedly connected between the two first connecting seats 8, and a slide seat 10 is commonly mounted on the two guide rods 9 in a damping sliding manner;

[0035] A fixing assembly 6 is fixedly mounted on a side of the slide seat 10 away from the backing plate 3 .

[0036] The fixing assembly 6 includes a second connecting seat 11, and the second connecting seats 11 are fixedly installed on the side of the sliding seat 10 away from the pad 3 near the two ends thereof, and a bidirectional screw rod 14 is rotatably installed between the two second connecting seats 11, and two sliding rods 13 symmetrically distributed about the bidirectional screw rod 14 are fixedly connected between the two second connecting seats 11;

[0037] Two sliders 15 symmetrically distributed about the middle position of the bidirectional screw rod 14 are installed on the outer periphery of the bidirectional screw rod 14 by through-threading, and the sliders 15 are through-slidably connected with the two slide rods 13. A clamping block 16 is fixedly installed on the side of the slider 15 away from the slide seat 10. The clamping block 16 is an arc-shaped structure, and the inner arc sides of the two clamping blocks 16 are arranged opposite to each other;

[0038] One end of the bidirectional screw rod 14 rotates and passes through the second connecting seat 11 at the corresponding position, and a tension knob 12 is fixedly installed thereon.

[0039] The protection component includes a spring 17, and a plurality of springs 17 are fixedly installed in an array on the inner arc surface of the clamp block 16 along its length direction, and an arc-shaped rubber clamp plate 18 is fixedly connected to one end of the plurality of springs 17 away from the clamp block 16, and the outer arc surface of the arc-shaped rubber clamp plate 18 is arranged opposite to the inner arc surface of the clamp block 16;

[0040] A plurality of protection grooves 19 are evenly formed on the inner arc surface of the arc-shaped rubber clamping plate 18 .

[0041] When the utility model is in use:

[0042] Align the pad 3 and place it on the philtrum of the patient, and then fix the device body through two ear hooks 2;

[0043] Then, the slide seat 10 is slid on the guide rod 9 in the adjustment component 5 so that the fixing component 6 is aligned with the nostril where the feeding tube needs to be inserted; when the feeding tube needs to be fixed, the two-way screw rod 14 is first rotated by the tension knob 12, and the two sliders 15 slide away from each other on the slide rod 13, so that the installation space between the two clamping blocks 16 is in the maximum state, and then the outer periphery of the feeding tube is placed between the two clamping blocks 16, and then the two-way screw rod 14 is rotated by the tension knob 12 so that the two sliders 15 slide towards each other on the slide rod 13, thereby driving the two clamping blocks 16 to clamp and fix the feeding tube.

[0044] Therefore, in the utility model, the elastic band, the ear hook, the pad, the adjustment component 5 and the fixing component 6 are arranged in coordination, so as to replace the adhesive tape to realize the fixing function of the feeding tube, thereby avoiding the problem that the patient may be allergic to the adhesive and cause discomfort; at the same time, the fixing component 6 fixes the feeding tube with a mechanical structure, which has high stability, and the fixing component 6 can realize the rapid loosening and clamping of the feeding tube, which is convenient for subsequent position adjustment and replacement of the feeding tube; the adjustment component 5 can flexibly adjust the position of the fixing component 6 under the patient's nose, so as to facilitate the adjustment of the fixing component 6 to a suitable working position, which is suitable for different patients and provides convenience for the fixing of the feeding tube.

[0045] Some patients may have an allergic reaction to the adhesive in the tape, resulting in discomfort symptoms such as itching, redness, swelling or pain. The stickiness of the tape used to fix the nasogastric tube may weaken over time, causing the tape to accidentally fall off, making the feeding tube unstable or displaced. Once the feeding tube is fixed with tape, it is inconvenient to replace or adjust the position of the feeding tube.

[0046] In the protection component, the inner arc side of the arc-shaped rubber splint 18 contacts the periphery of the feeding tube. The elastic force of the spring 17 and the soft characteristics of the arc-shaped rubber splint 18 itself make the arc-shaped rubber splint 18 and the feeding tube in elastic extrusion contact, thereby avoiding the deformation of the feeding tube due to rigid extrusion, which affects the normal use of the feeding tube, and improves the protection of the feeding tube; wherein the provision of the protection groove 19 can effectively increase the static friction between the periphery of the feeding tube and the arc-shaped rubber splint 18, thereby improving the fixing stability of the feeding tube.
