Description

Technical Field

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

[0002] Nasogastric tube (nasointestinal tube) placement is an important means of enteral nutrition, intragastric treatment, gastrointestinal decompression and gastric lavage, and certain measures are usually required for proper fixation. Currently, 3M elastic soft cotton tape and gauze cotton rope are commonly used in clinical practice to fix nasogastric tubes. When using 3M elastic soft cotton tape for fixation, the tape needs to be cut into a suitable shape before sticking, and when the patient sneezes or coughs repeatedly, the tape is prone to loosening and slipping off; in addition, during the long-term retention of the nasogastric tube, when the human body secretes more oil or sweats due to hot weather, the adhesion effect of the tape attached to the nose tip will be reduced, resulting in the risk of the nasogastric tube slipping off. When using tape for long-term fixation, a gelatinous film is likely to remain on the nasogastric tube, and when the tape needs to be replaced, medical staff need to tear the tape repeatedly, which will affect the patient's treatment comfort. At the same time, the characteristic of the tape that is not easy to tear will also increase the workload of medical staff to a certain extent.

[0003] When using gauze cotton rope for fixation, it is also necessary to cut the size before use, and then tie and fix it in the appropriate position. However, the knotted part of the cotton rope is often loose, and when the patient is agitated and pulls it, it is easy to cause the nasogastric tube to fall out, which makes it easy for the patient to aspirate or even choke and suffocate during the later nasogastric feeding process.

[0004] In view of this, it is necessary to design a nasogastric tube fixing device to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a nasogastric tube fixing device that will not cause the nasogastric tube to fall off due to oily skin or sneezing, coughing, etc., and can avoid the patient from performing unplanned tube removal. At the same time, the nasogastric tube fixing position can be adjusted according to the sleeping posture to increase the patient's comfort and avoid the formation of pressure sores.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A nasogastric tube fixing device, comprising:

[0008] The external nose fixing part is fixed on the patient's external nose;

[0009] a limiting member connected to the external nasal fixing portion and used to fix the nasogastric tube section close to the nostril;

[0010] Fixing components, two fixing components are respectively connected to the two sides of the external nasal fixing part, and the fixing components include an upper fixing tube and a lower fixing tube with openings on the tube body, so that a portion of the nasogastric tube can be buried and fixed in either fixing tube through the opening;

[0011] a connecting assembly detachably connected to the fixing assembly, comprising an upper connecting strap connected to one upper fixing tube at one end and having its other end passed over the ear and connected to another upper fixing tube at the other end, and a lower connecting strap connected to one lower fixing tube at one end and having its other end passed under the ear and connected to another lower fixing tube at the other end, so that the external nose fixing portion, the upper fixing tube, the upper connecting strap, and the lower fixing tube and the lower connecting strap together form a double-layer fixing structure surrounding the head;

[0012] The limiting belt is located between the two ears and is used to connect the upper connecting belt and the lower connecting belt to play a limiting role.

[0013] As a further improvement of the present invention, the limiting member is detachably connected to the section of the nasogastric tube near the nostrils.

[0014] As a further improvement of the present invention, the limiting member includes two arc-shaped structures connected at one end by a rotating pair and snap-connected at the other end to form a circular ring, and the inner diameter of the circular ring is smaller than the diameter of the nasogastric tube.

[0015] As a further improvement of the present invention, the snap-fit ​​connection ends of the two arc-shaped structures are provided with at least two snap-fit ​​locations to form circular rings of different diameters.

[0016] As a further improvement of the present invention, the opening is arranged along the axial direction of the fixed tube, and the width of the opening is smaller than the diameter of the nasogastric tube.

[0017] As a further improvement of the present invention, the upper fixing tube extends from one side of the external nose fixing portion to the side of the zygomatic bone close to the ear.

[0018] As a further improvement of the present invention, the upper fixed tube and the lower fixed tube are equal in length.

[0019] As a further improvement of the present invention, the connecting belt is detachably connected to at least one fixing tube.

[0020] As a further improvement of the present invention, the diameter of the fixed tube is larger than the diameter of the nasogastric tube, and both ends of the fixed tube are open to facilitate the passage of the nasogastric tube.

[0021] As a further improvement of the present invention, a fixing ring is provided at one end of the fixing tube away from the external nose fixing portion for facilitating the passage of the connecting belt.

[0022] As a further improvement of the present invention, the external nose fixing portion is a nose mask structure that covers both sides of the nose wings and part of the nose bridge.

[0025] 1. The present invention forms a fixing structure surrounding the head through an external nasal fixing part, a fixing tube and a connecting belt, wherein a limit piece provided on the external nasal fixing part is used to perform preliminary fixation of the nasogastric tube, and at the same time, the section of the nasogastric tube away from the nasal cavity is fixed in the fixing tube for secondary fixation, which can effectively improve the fixation effect of the nasogastric tube. The design of placing the nasogastric tube in the fixing tube can reduce the exposure of the nasogastric tube. When the patient wants to accidentally remove the tube, not only does he need to accurately find the exposed nasogastric tube, but he also needs to remove the nasogastric tube fixing device as a whole, so that there is double resistance during the accidental extubation process, which can greatly reduce the possibility of the patient extubating himself.

[0026] 2. The utility model is provided with two upper and lower fixed tubes. When the patient lies flat, the nasogastric tube can be placed in the upper fixed tube or the lower fixed tube, and when the patient lies on his side, the nasogastric tube can be placed in the lower fixed tube to prevent the nasogastric tube from squeezing the facial skin and causing discomfort and forming pressure sores.

[0027] 3. By setting up two upper and lower connecting straps, the fixing tube and the connecting strap can cooperate to achieve double-layer fixation around the head, thereby improving the fixing effect. At the same time, by setting a limiting strap connecting the upper connecting strap and the lower connecting strap between the two ears, the upper and lower connecting straps can also play a role in limiting and fixing each other, thereby preventing the upper connecting strap from detaching upward from the head and the lower connecting strap from detaching downward from the head.

[0028] 4. The detachable connection arrangement of the connecting component and the fixing component of the present invention facilitates adjustment of the length of the connecting belt according to the patient's head circumference to meet the usage needs of patients with different head circumferences.

[0037] It should also be noted here that, in order to avoid obscuring the present invention due to unnecessary details, only structures and / or processing steps closely related to the scheme of the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0038] In addition, it should be noted that the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0039] See also Figure 1-Figure 5 As shown, the utility model provides a nasogastric tube fixing device, comprising:

[0040] The external nose fixing portion 20 is fixed to the patient's external nose 11;

[0041] The limiting member 30 is connected to the external nose fixing portion 20 via a connecting member and is used to fix the section of the nasogastric tube 70 near the nostril;

[0042] Two fixing assemblies are connected to both sides of the external nasal fixing portion 20, respectively. The fixing assemblies include an upper fixing tube 41 and a lower fixing tube 42, each of which has an opening 43 on the tube body, so that a portion of the nasogastric tube 70 can be buried and fixed in either fixing tube through the opening 43;

[0043] The connecting assembly includes an upper connecting strap 51 with one end detachably connected to an upper fixing tube 41 and the other end passing over the ear portion 12 to be detachably connected to the other upper fixing tube 41, and a lower connecting strap 52 with one end detachably connected to a lower fixing tube 42 and the other end passing under the ear portion 12 to be detachably connected to the other lower fixing tube 42, so that the external nose fixing portion 20, the upper fixing tube 41, the upper connecting strap 51, and the lower fixing tube 42 and the lower connecting strap 52 together form a double-layer fixing structure surrounding the head;

[0044] The limiting belt 60 is located between the two ears 12 and is used to connect the upper connecting belt 51 and the lower connecting belt 52 to play a limiting role.

[0045] Exemplarily, the limiting belt 60 is a connecting rope, one end of which is connected to the upper connecting belt 51, and the other end is connected to the lower connecting belt 52 at the corresponding position. Combined with the limiting effect of the ears 12 on the connecting belts, the upper and lower connecting belts can be fixed on the head while utilizing the mutual limiting effect of the two connecting belts to prevent the upper connecting belt 51 from detaching upward from the head and the lower connecting belt 52 from detaching downward from the head.

[0046] Specifically, such as Figure 2 As shown, the external nose fixing portion 20 is a nasal mask structure that covers both sides of the nose and part of the nose bridge. By attaching the nasal mask structure to the external nose 11, the external nose 11 can be used as a fixing point, facilitating the combination of the external nose fixing portion 20, the fixing tube, and the connecting strap to form a fixed structure. Exemplarily, the external nose fixing portion 20 is made of silicone. This facilitates cleaning and disinfection of the external nose fixing portion 20 when the skin is oily or dirty, thereby extending the service life of the external nose fixing portion 20 while preventing oily skin from affecting the fixation effect of the nasogastric tube fixation device.

[0047] Specifically, the stopper 30 is detachably connected to the section of the nasogastric tube 70 near the nostril, so that the section of the nasogastric tube 70 near the nostril and the external nasal fixing portion 20 remain relatively fixed, thereby achieving preliminary fixation of the nasogastric tube 70; for example, Figure 3 As shown, the limiting member 30 includes two arc-shaped structures connected at one end by a rotating pair 31 and snap-connected at the other end to form a circular ring. The inner diameter of the circular ring is slightly smaller than the diameter of the nasogastric tube 70, so that after the nasogastric tube 70 passes through the two arc-shaped structures, the nasogastric tube 70 is clamped by the cooperation of the two arc-shaped structures, so that the nasogastric tube 70 and the external nasal fixing part 20 remain relatively fixed; in particular, the snap-connecting ends of the two arc-shaped structures are provided with at least two snap-connecting sites (not shown in the figure) to form circular rings of different diameters to adapt to the fixation requirements of nasogastric tubes of different diameters.

[0048] Specifically, such as Figure 4 and Figure 5 As shown, the diameter of the fixing tube is larger than the diameter of the nasogastric tube 70; the opening 43 on the fixing tube is arranged along the axial direction of the fixing tube; the width of the opening 43 is smaller than the diameter of the nasogastric tube 70, so that after the nasogastric tube 70 is placed inside the tube body of the fixing tube through the opening 43, the nasogastric tube 70 is fixed by the fixing tube while preventing the nasogastric tube 70 from escaping from the fixing tube through the opening 43 due to the opening 43 being too large. The specific width of the opening 43 can be adjusted according to actual conditions so that the nasogastric tube 70 is not easily escaping from the fixing tube through the opening 43.

[0049] Both ends of the fixing tube are open to facilitate the passage of the nasogastric tube 70; at the same time, a fixing ring 44 is also provided at the end of the fixing tube away from the external nasal fixing part 20. The connecting belt is passed through the fixing ring 44 for fixing to achieve a detachable connection between the fixing belt and the connecting belt. By adjusting the length of the connecting belt passing through the fixing ring 44, the circumference of the fixing structure can be adjusted, so that the nasogastric tube 70 fixing device can be suitable for patients with different head circumferences. For example, the detachable connection between the connecting belt and the fixing ring 44 can be achieved through a Velcro adhesive structure, that is, a Velcro hook surface is provided at the end of the connecting belt, and a Velcro cotton surface is provided at the corresponding connecting belt position, so that the end of the connecting belt passes through the fixing ring 44 and adheres to the corresponding Velcro cotton surface position to complete the fixation of the connecting belt and the fixing ring 44.

[0050] The upper fixing tube 41 extends from the side of the external nasal fixing portion 20 to the side of the cheekbone near the ear 12, while the lower fixing tube 42 extends from the side of the external nasal fixing portion 20 to below the ear 12. In this embodiment, the upper and lower fixing tubes 41 and 42 are of equal length. Because the four fixing tubes are positioned in different directions, the nasogastric tube 70 can be fixed in any of the four fixing tubes during use, depending on the patient's posture, thereby reducing pressure on the face from the nasogastric tube 70.

[0051] Specifically, the fixing tube is made of a material with a certain degree of flexibility; illustratively, the fixing tube extends toward the ear portion 12 in a certain curvature.

[0052] The working principle of the nasogastric tube fixing device of the present invention is described below:

[0053] During use, the part of the nasogastric tube 70 close to the nostrils is engaged in the limiter 30 for preliminary fixation; the nasogastric tube 70 is placed in one of the fixed tubes through the opening 43 according to the patient's sleeping position, so that the part of the nasogastric tube 70 is placed in the fixed tube as a whole, and the nasogastric tube 70 is fixed for a second time using the fixed tube. Since the nasogastric tube 70 is buried in the fixed tube, the exposure of the nasogastric tube 70 is reduced, which not only reduces the discomfort caused by the swinging of the exposed nasogastric tube 70, but also reduces to a certain extent the risk of the nasogastric tube 70 falling off due to the patient pulling the nasogastric tube 70 in a restless state; when it is necessary to clean the external nasal fixing part 20, the nasogastric tube fixing device can be placed in a slightly loose state by adjusting the length of the connecting belt, thereby facilitating the cleaning of the external nasal fixing part 20.

[0054] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention.
