Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical devices, in particular to a nasogastric tube with a nose skin damage prevention structure and a method. BACKGROUND

[0002] In clinical nasogastric therapy, the nasogastric tube needs to be left in the patient's nasal cavity for a long time, and its fixation and protection effect directly affect the patient's use experience and the health of the nasal skin. Currently, the commonly used fixation method of the nasogastric tube in the clinic relies on adhesive tape to be pasted on both sides of the alae nasi or the cheeks to achieve limiting.

[0003] The fixation method of the nasogastric tube in the prior art has poor stability in use. During the insertion, adjustment or daily activities of the patient, the nasogastric tube is prone to displacement and sliding, which causes repeated friction between the nasogastric tube and the nasal skin, resulting in skin redness, damage and even ulceration. Especially for patients with sensitive skin or long-term bedridden, the risk of damage is significantly increased. Moreover, the wearing portability of the existing nasogastric tube is poor. Some auxiliary fixation devices are large in size and complicated to wear. After being worn by the patient, the comfort is low, and it is difficult to adapt to the daily activity needs of the patient, further increasing the probability of displacement and skin friction of the nasogastric tube caused by the movement of the patient.

[0004] Based on the above reasons, the present application provides a nasogastric tube with a nose skin damage prevention structure and a method, which can achieve stable limiting of the nasogastric tube, reduce damage to the nasal skin and be firmly worn. SUMMARY

[0005] The technical problem solved by the present application is to overcome the defects of the prior art and provide a nasogastric tube with a nose skin damage prevention structure and a method, which has good stability and is firmly and stably worn.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical scheme: a nasogastric tube with a nose skin damage prevention structure, comprising a nasogastric tube main body, a plurality of annular plates are sleeved on the nasogastric tube main body, a plurality of connecting ropes are uniformly distributed and sleeved on the annular plates, the connecting ropes are fixedly connected with the uppermost annular plate, and the lower ends of the connecting ropes are provided with winding assemblies, a first spring is sleeved on each connecting rope between the annular plates, the ends of the first spring are fixedly connected with the annular plates on both sides, an arc-shaped plate is arranged on the front side of the lowermost annular plate, a connecting assembly is arranged between the arc-shaped plate and the annular plate, side grooves are formed on both sides of the arc-shaped plate, and ear hanging assemblies are fixedly connected in the side grooves.

[0007] Preferably, the winding assembly includes a movable shaft, which is inserted into and movably connected to an annular plate. A wheel is fixedly connected to the bottom end of the movable shaft, and a side hole is provided at the top end of the movable shaft. Two positioning rods are symmetrically and movably connected in the side hole. A second spring is fixedly connected between the two positioning rods. A positioning groove is provided on the annular plate near the positioning rods. The end of the positioning rod away from the second spring extends out of the side hole and is inserted into the positioning groove. The bottom end of the connecting rope is fixedly connected to the movable shaft.

[0008] Preferably, the connecting assembly includes a first side plate, which is movably connected to the arc-shaped plate, and a second side plate is fixedly connected to the side of the first side plate away from the arc-shaped plate. The second side plate is movably connected to the annular plate, and positioning bolts are threaded onto the top surfaces of both the first and second side plates.

[0009] Preferably, the ear-hanging assembly includes a movable plate, which is movably connected to the side groove, and a third spring is fixedly connected to one side of the movable plate in the inner cavity of the side groove. The other end of the third spring is fixedly connected to the inner wall of the side groove. A vertical plate is fixedly connected to the end of the movable plate away from the third spring, and a hanging plate is fixedly connected to the top surface of the vertical plate.

[0010] Preferably, a threaded sleeve is fixedly connected to the side wall of the arc-shaped plate away from the annular plate, a threaded rod is threadedly connected to the threaded sleeve, and a support plate is fixedly connected to the other end of the threaded rod.

[0011] Preferably, the side wall of the arc-shaped plate is provided with a movable groove, and the side wall of the lowest annular plate is provided with another movable groove. The first side plate and the second side plate are both concave, and a sliding plate is fixedly connected to the inner side wall of the first side plate and the second side plate. The sliding plate is inserted into the movable groove, and the sliding plate is movably connected to the movable groove.

[0012] Preferably, a self-inflating air bladder is fixedly connected to the inner wall of the annular plate, and the inner wall of the self-inflating air bladder is closely attached to the inner wall of the nasogastric tube body.

[0013] A method for using a nasogastric tube with a nasal skin protection structure includes the following steps: S1: Medical staff rotate the support plate according to the patient's needs, so that the threaded rod rotates in the threaded sleeve, changing the position of the support plate to adapt to the patient's needs, and rotate the ring plate to change the position of the connecting rope on the ring plate, and push the first side plate to the position of the patient's nostril as needed, so that the ring plate moves to the designated position on the arc plate, and then rotate the two positioning bolts to fix the first side plate to the arc plate and the second side plate to the ring plate. S2: Pull the vertical plates on both sides in the opposite direction. The vertical plates drive the movable plate to move in the side groove on the arc plate. The third spring is stretched. While ensuring that the ring plate is inserted into the patient's nasal cavity, place the hanging plate on the patient's ear. Release the vertical plates. Under the elastic force of the third spring, the vertical plates are clamped on both sides of the patient's face, and the support plate is placed against the patient's philtrum, so that the main body of the nasogastric tube can be placed at the patient's nostril. S3: The medical staff then rotates the wheel according to the condition of the patient's nasal cavity. The wheel drives the movable shaft to rotate, which in turn winds up the connecting rope. At this time, because the winding length of the connecting rope is different at different positions, the ring plate can tilt. The elastic force of the first spring ensures the stability of the ring plate, thereby limiting the movement trajectory of the nasogastric tube body inside the nasal cavity. The elastic force of the second spring causes the positioning rod to be inserted into the positioning groove in the ring plate, thus fixing the movable shaft. S4: At this time, medical staff can operate the main body of the nasogastric tube so that it can be inserted into the patient's stomach without contacting the nasal cavity wall as much as possible, reducing damage to the nasal skin during the insertion process. After the main body of the nasogastric tube is inserted, the self-inflating air bag is opened, so that the self-inflating air bag expands and clamps the main body of the nasogastric tube. Under the elastic force of the first spring, the stability of the main body of the nasogastric tube is ensured, so that the main body of the nasogastric tube does not come into contact with the patient's nasal skin during use, further reducing the impact on the patient's skin. S5: When the patient moves while carrying the nasogastric tube, the vertical plates on both sides can be effectively clamped to the patient's face under the elastic force of the third spring, thus limiting the left and right swing of the nasogastric tube. Furthermore, the suspension and fixation between the hanging plate and the patient's ear can reduce the up and down swing of the nasogastric tube, effectively improving the stability of the nasogastric tube and reducing damage to the patient's nasal skin caused by the patient's movement.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. The present invention uses multiple annular plates to limit the main body of the nasogastric tube, and uses a self-inflating air bladder to expand and clamp the main body of the nasogastric tube. Under the elastic force of the first spring, the limiting stability of the main body of the nasogastric tube is ensured, so that the main body of the nasogastric tube does not come into contact with the patient's nasal skin during use, reducing the impact on the patient's skin. 2. This invention rotates a rotating wheel, which drives a movable shaft to rotate, causing the movable shaft to wind up the connecting rope. Because the winding length of the connecting rope is different at different positions, the annular plate can tilt. The elastic force of the first spring ensures the stability of the annular plate, thereby limiting the movement trajectory of the nasogastric tube body inside the nasal cavity. The elastic force of the second spring causes the positioning rod to be inserted into the positioning groove in the annular plate, thus fixing the movable shaft. This facilitates the insertion and use of the nasogastric tube body and reduces damage to the patient's nasal skin. 3. Under the elastic force of the third spring, the vertical plates on both sides can be clamped to the patient's face, thereby limiting the left and right swing of the nasogastric tube. Furthermore, the suspension and fixation between the hanging plate and the patient's ear can reduce the up and down swing of the nasogastric tube, effectively improving the stability of the nasogastric tube and thus reducing the damage to the patient's nasal skin caused by the patient's movement.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Example 1: Please refer to Figures 1-7 The present invention provides a technical solution: a nasogastric tube with a nasal skin protection structure, including a nasogastric tube body 1, a plurality of annular plates 2 are sleeved on the nasogastric tube body 1, and connecting ropes 3 are evenly distributed on the annular plates 2. The connecting ropes 3 are fixedly connected to the uppermost annular plate 2. A first spring 5 is sleeved on each connecting rope 3 between the annular plates 2. The two ends of the first spring 5 are fixedly connected to the annular plates 2 on both sides respectively. A self-inflating airbag 26 is fixedly connected to the inner wall of the annular plate 2. The inner wall of the self-inflating airbag 26 is tightly attached to the inner wall of the nasogastric tube body 1. In the technical solution of this embodiment, the nasogastric tube body 1 is limited by multiple annular plates 2, and is clamped to the nasogastric tube body 1 by the expansion of the self-inflating air bag 26. Under the elastic force of the first spring 5, the limiting stability of the nasogastric tube body 1 is ensured, so that the nasogastric tube body 1 does not come into contact with the patient's nasal skin during use, reducing the impact on the patient's skin. Furthermore, a winding assembly 4 is provided at the lower end of the connecting rope 3. The winding assembly 4 includes a movable shaft 9, which is inserted into and movably connected to the annular plate 2. A rotating wheel 10 is fixedly connected to the bottom end of the movable shaft 9, and a side hole 11 is provided at the top end of the movable shaft 9. Two positioning rods 12 are symmetrically and movably connected in the side hole 11, and the same second spring 13 is fixedly connected between the two positioning rods 12. A positioning groove is provided in the annular plate 2 near the positioning rods 12. The end of the positioning rod 12 away from the second spring 13 extends out of the side hole 11 and is inserted into the positioning groove. The bottom end of the connecting rope 3 is fixedly connected to the movable shaft 9. In the technical solution of this embodiment, medical staff rotate the wheel 10 according to the condition of the patient's nasal cavity. The wheel 10 drives the movable shaft 9 to rotate, so that the movable shaft 9 winds up the connecting rope 3. At this time, because the winding length of the connecting rope 3 at different positions is different, the annular plate 2 can be tilted. The elastic force of the first spring 5 ensures the stability of the annular plate 2, thereby limiting the movement trajectory of the nasogastric tube body 1 inside the nasal cavity. The elastic force of the second spring 13 causes the positioning rod 12 to be inserted into the positioning groove in the annular plate 2, thereby fixing the movable shaft 9. This facilitates the insertion and use of the nasogastric tube body 1 and reduces damage to the patient's nasal skin. An arc-shaped plate 6 is provided at the front side of the lowest annular plate 2. A connecting assembly 7 is provided between the arc-shaped plate 6 and the annular plate 2. The connecting assembly 7 includes a first side plate 14, which is movably connected to the arc-shaped plate 6. A second side plate 15 is fixedly connected to the side of the first side plate 14 away from the arc-shaped plate 6. The second side plate 15 is movably connected to the annular plate 2. Positioning bolts 16 are threaded onto the top surfaces of both the first side plate 14 and the second side plate 15. A movable groove 24 is provided on the side wall of the arc-shaped plate 6. Another movable groove 24 is provided on the side wall of the lowest annular plate 2. Both the first side plate 14 and the second side plate 15 are... The design features a concave shape, with slide plates 25 fixedly connected to the inner walls of both the first side plate 14 and the second side plate 15. The slide plates 25 are inserted into the movable slots 24, and the slide plates 25 are movably connected to the movable slots 24. By rotating the annular plate 2, the position of the connecting rope 3 on the annular plate 2 is changed, and the first side plate 14 is pushed according to the required position of the patient's nostril, causing the annular plate 2 to move to the designated position on the arc plate 6. Then, the two positioning bolts 16 are rotated to fix the first side plate 14 to the arc plate 6 and the second side plate 15 to the annular plate 2, facilitating precise operation.

[0019] Example 2: Please refer to Figures 1-7 Based on Embodiment 1, and with side grooves on both sides of the arc plate 6, a hanging ear assembly 8 is fixedly connected in each side groove. The hanging ear assembly 8 includes a movable plate 17, which is movably connected to the side groove. A third spring 18 is fixedly connected to one side of the movable plate 17 in the inner cavity of the side groove. The other end of the third spring 18 is fixedly connected to the inner wall of the side groove. A vertical plate 19 is fixedly connected to the end of the movable plate 17 away from the third spring 18. A hanging plate 20 is fixedly connected to the top surface of the vertical plate 19. In the technical solution of this embodiment, when the patient moves while carrying the nasogastric tube body 1, the vertical plates 19 on both sides can be effectively clamped to the patient's face under the elastic force of the third spring 18, thereby limiting the left and right swing of the nasogastric tube body 1. Furthermore, the suspension and fixation between the hanging plate 20 and the patient's ear can reduce the up and down swing of the nasogastric tube body 1, effectively improving the stability of the nasogastric tube body 1 and thus reducing the damage to the patient's nasal skin caused by the patient's movement. A threaded sleeve 21 is fixedly connected to the side wall of the arc plate 6 away from the annular plate 2. A threaded rod 22 is connected to the threaded sleeve 21. A support plate 23 is fixedly connected to the other end of the threaded rod 22. This allows for adjustment of the distance between the arc plate 6 and the patient's philtrum, facilitating stable wearing of the device.

[0020] A method for using a nasogastric tube with a nasal skin protection structure includes the following steps: S1: Medical staff rotate the support plate 23 according to the patient's needs, so that the threaded rod 22 rotates in the threaded sleeve 21, changing the position of the support plate 23 to adapt to the patient's needs, and rotate the annular plate 2 to change the position of the connecting rope 3 on the annular plate 2, and push the first side plate 14 to the position of the patient's nostril as needed, so that the annular plate 2 moves to the designated position on the arc plate 6, and then rotate the two positioning bolts 16 to fix the first side plate 14 to the arc plate 6 and the second side plate 15 to the annular plate 2. S2: Pull the vertical plates 19 on both sides in the opposite direction. The vertical plates 19 drive the movable plate 17 to move in the side groove on the arc plate 6. The third spring 18 is stretched. While ensuring that the annular plate 2 is inserted into the patient's nasal cavity, place the hanging plate 20 on the patient's ear, release the vertical plates 19. Under the elastic force of the third spring 18, the vertical plates 19 are clamped on both sides of the patient's face, and the support plate 23 is pressed against the patient's philtrum, so that the nasogastric tube body 1 is placed at the patient's nostril. S3: The medical staff then rotates the wheel 10 according to the condition of the patient's nasal cavity. The wheel 10 drives the movable shaft 9 to rotate, so that the movable shaft 9 performs a winding operation on the connecting rope 3. At this time, because the winding length of the connecting rope 3 at different positions is different, the annular plate 2 can be tilted. The elastic force of the first spring 5 ensures the stability of the annular plate 2, thereby completing the limitation of the movement trajectory of the nasogastric tube body 1 inside the nasal cavity. The elastic force of the second spring 13 causes the positioning rod 12 to be inserted into the positioning groove in the annular plate 2, thus completing the fixation of the movable shaft 9. S4: At this time, medical staff can operate the nasogastric tube body 1 so that the nasogastric tube body 1 can be inserted into the patient's stomach without contacting the nasal cavity wall as much as possible, reducing damage to the nasal skin during the insertion of the nasogastric tube body 1. After the nasogastric tube body 1 is inserted, the self-inflating air bag 26 is opened, so that the self-inflating air bag 26 expands and clamps the nasogastric tube body 1. Under the elastic force of the first spring 5, the nasogastric tube body 1 is kept in a stable position, so that the nasogastric tube body 1 does not come into contact with the patient's nasal skin during use, further reducing the impact on the patient's skin. S5: When the patient moves while carrying the nasogastric tube body 1, the vertical plates 19 on both sides can be effectively clamped to the patient's face under the elastic force of the third spring 18, thus limiting the left and right swing of the nasogastric tube body 1. Furthermore, the suspension and fixation between the hanging plate 20 and the patient's ear can reduce the up and down swing of the nasogastric tube body 1, effectively improving the stability of the nasogastric tube body 1 and thus reducing the damage to the patient's nasal skin caused by the patient's movement.
