Description

Technical Field

[0001] The present application relates to the technical field of medical supplies, and more specifically, to an improved nasogastric feeding tube fixing device. Background Art

[0002] Nasogastric feeding involves inserting a tube into the stomach through the nose and administering liquid food, water, and medication. It is commonly used for patients who are unable to eat independently, such as those in a coma, those with dysphagia caused by pseudobulbar palsy, and those with advanced esophageal cancer. These patients receive the nutrients they need to survive through the liquid food infused through the tube.

[0003] Currently, most nasogastric tubes used in clinical practice are simply smooth, flexible tubes without a fixing device. After being inserted from the patient's nasal cavity into the stomach, the tube often shifts. If the patient becomes agitated, the tube is more likely to dislodge from the stomach, causing food to overflow and leading to a series of complications. This not only increases the burden on medical staff and the patient's family, but more importantly, increases the pain of repeated intubation for the patient.

[0004] The prior art with the announcement number CN221206463U (application number 202322311017.6) discloses a nasogastric tube fixing device and system. Figure 3 The nasofeeding tube fixing device and system include a main unit, a fixing unit, a positioning unit, a clamping unit and a wearing unit. The main unit is nearly star-shaped; the fixing unit is arranged at the end of the main unit; the positioning unit is arranged in the middle of the main unit, and is used to limit the position of the nasofeeding tube fixing device on the patient's face; the clamping unit is placed at the lower part of the main unit and is detachably connected to the nasofeeding tube for fixing the feeding tube; the wearing unit is detachably connected to the fixing unit for fixing the nasofeeding tube fixing device to the patient's face. However, in this prior art, although the position of the nasofeeding tube fixing device on the patient's face can be limited by the positioning unit, because the facial features of the patients are not exactly the same, the nasofeeding fixing device cannot meet the needs of various patients; in addition, although the clamping unit is easy to clamp and disengage the nasofeeding tube, the clamping force of the clamping unit on the nasofeeding tube is relatively small, and the nasofeeding tube still has the hidden danger of disengagement.

[0005] The prior art with the publication number CN220125124U (application number 202321545136.1) discloses a nasogastric tube holder that is easy to adjust. Figure 4The nasogastric tube holder includes a nasal mask, a head strap, and a back-of-the-head strap. The two sides of the nasal mask are connected by the head strap, and the back-of-the-head strap is provided in the middle of the head strap. The nasal mask is annular in structure, and the shape of the interior of the nasal mask matches the shape of the nose. The nasal mask is provided with a nasal mask base, which is located below the nostrils. The nasal mask base is detachably provided with a movable bracket, and the end of the movable bracket is provided with a buckle. The buckle is an annular ring with an adjustable size, which is used to fix the nasogastric tube by adjusting the position of the movable bracket. However, in this prior art, the nasal mask is fixed to the nose by relying on the head strap and the back-of-the-head strap, wherein the head strap and the back-of-the-head strap are not limited. However, in the prior art, the nasal mask is annular in structure, and the shape of the inside of the nasal mask matches the shape of the nose, and the nasal mask is located on the outside of the nose. Since patients have different ages and nationalities, the curve characteristics of the patients' noses are not exactly the same, and a universal nasal mask is difficult to adapt to the noses of all patients. In addition, a nasal mask base is provided under the nasal mask. The nasal mask base is located below the nostrils, that is, at the philtrum. The nasal mask base is detachably provided with a movable bracket. Since the philtrum position is very limited, the nasal mask base is likely to occupy the philtrum position of most people and it is difficult to accommodate the movable bracket, resulting in the movable bracket blocking the patient's mouth and affecting the patient's normal mouth movement.

[0006] In addition, the prior art with announcement number CN219049591U (application number 202320121362.0) discloses a nasogastric tube locator, which retains the traditional method of fixing with adhesive tape on the skin. This prior art method is not only not firm, but also easily causes skin allergies in patients who are allergic to adhesive components, increasing the patient's physical discomfort. And some prior art (announcement number CN215461177U, application number 202121024476.0) discloses a nasal sleeve for fixing the nasal cannula, which is only fixed and connected to the patient's nose through the nasal sleeve, and the firmness is low. After the patient's skin sweats or there are large movements on the face, the nasal sleeve is easy to fall off, and thus the reliability of the fixation of the nasal cannula cannot be guaranteed. The prior art with announcement number CN217091453U (application number 202123138301.5) discloses a nasogastric tube fixation auxiliary device. The nasogastric tube is passed from the patient's mandible through the mouth to the nostril. During the nasogastric feeding process, it will affect the normal movement of the mouth. Moreover, if the patient speaks or makes other movements during the nasogastric feeding process, it will cause the nasogastric tube to move significantly, thereby increasing the patient's discomfort. The prior art with announcement number CN219271638U (application number 202223340565.3) discloses a nasogastric tube fixator with a complex structure. It occupies a large space on the patient's face, and the fixing process of the nasogastric tube is complicated.

[0007] Based on the existing technology, it is very necessary to design a nasogastric tube fixing device that is comfortable and does not affect the patient's normal facial movements while ensuring firmness. Utility Model Content

[0008] In view of this, the present application provides an improved nasogastric feeding tube fixing device, which aims to improve the problems of low usage comfort and impact on patient facial movements in the existing technology, enhance comfort, and reduce the effect of nasogastric feeding on frontal facial movements.

[0010] The fixing assembly includes a nose bridge bar and two nose alar side bars, the nose alar side bars extending longitudinally, the two nose alar side bars being arranged opposite to each other in the transverse direction, the nose bridge bar being arranged between the two nose alar side bars, and the two ends of the nose bridge bar being respectively connected to the upper parts of the two nose alar side bars; the nose bridge bar and the two nose alar side bars are further provided with reinforcement bars, the reinforcement bars being plastically deformable strip-shaped parts, the reinforcement bars of the nose alar side bars being arranged along the extension direction of the nose alar side bars, and the reinforcement bars of the nose bridge bar extending transversely;

[0011] The wearing component is connected to the fixing component; the wearing component includes two straps, and the two ends of each strap are respectively connected to the upper and lower parts of one of the nose alar side strips, and the straps are suitable for passing over the back of the patient's ears to fix the straps to the patient's face; or, the wearing component includes a plurality of straps, at least one strap has one end connected to the upper part of one of the nose alar side strips and the other end connected to the upper part of another of the nose alar side strips, and at least one strap has one end connected to the lower part of one of the nose alar side strips and the other end connected to the lower part of another of the nose alar side strips;

[0012] The locking mechanism is configured to lock the locking cam of the locking cam, wherein the locking cam is secured to the locking cam of the locking cam and secured to the pivot point of the locking cam.

[0013] The sliding bar is slidably connected to the positioning cylinder, the positioning cylinder is provided with a connecting ring portion, the connecting ring portion is provided with a connecting through hole along the transverse direction, and the sliding bar is passed through the connecting through hole;

[0014] The sliding bar is provided with a plurality of protrusions, which extend longitudinally and are arranged transversely. The protrusions are located on a side of the sliding bar close to the clamping cylinder, and the spacing between two adjacent protrusions is not less than the transverse dimension of the clamping cylinder. The protrusions abut against the outer wall of the clamping cylinder to limit the clamping cylinder in the transverse direction.

[0015] The limiting member includes an annular flange and an annular groove. The annular flange is provided on the outer circumference of the clamping cylinder, the annular groove is provided on the inner circumference of the positioning cylinder, and the annular flange passes through the annular groove.

[0016] Optionally, the reinforcement strip is a metal wire.

[0017] Optionally, the cross-section of the protrusion is triangular or trapezoidal.

[0018] Optionally, the nasogastric tube fixing device further includes a tightness adjusting piece, and the tightness adjusting piece is sleeved on the lace.

[0019] Compared with the prior art, the improved nasogastric tube fixing device provided in this application achieves at least the following beneficial effects:

[0020] (1) In an improved nasogastric tube fixing device provided by the present application, the fixing component includes a nose bridge bar and two nose wing side bars, and the nose bridge bar and the two nose wing side bars are also provided with reinforcement strips. The reinforcement strips are plastically deformable strips. The reinforcement strips of the nose wing side bars are arranged along the extension direction of the nose wing side bars, and the reinforcement strips of the nose bridge bar are arranged along the transverse extension. In this way, the nose wing side bars and the nose bridge bar can be appropriately adjusted and deformed according to the patient's nose shape. The nose wing side bars and the nose bridge bar are respectively tightly attached to the depression between the patient's nose wing and the face and the nose bridge. The fixing component can be adjusted and deformed according to the individual facial features of the patient, so that the fixing component can fit the patient's face firmly and achieve positioning. After the patient is connected to the patient's head through the wearing component, even if the patient's head moves, it can ensure that the nasogastric tube fixing device is not easy to change its position on the patient's face. It is firm and stable, which is conducive to preventing the nasogastric tube from continuing to enter and exit the nasal cavity. The fixing component contacts the patient's facial skin in a large and dispersed manner, reducing the pressure of the fixing component on the patient's face and improving the user experience. In addition, the fixed component has a simple structure and is easy to install. It does not block a large area of the patient's face and does not affect the patient's normal mouth movements, which is beneficial for medical staff to observe the patient's face in a timely manner.

[0021] (2) In an improved nasogastric tube fixing device provided by the present application, the positioning component includes a clamping cylinder. The nasogastric tube can be fixed to the clamping through hole through the clamping notch to achieve clamping and fixing of the nasogastric tube. However, due to the existence of the clamping notch, the nasogastric tube still has the risk of escaping from the clamping through hole. For this reason, in this embodiment, the positioning component also includes a positioning cylinder. The clamping cylinder and the positioning cylinder are coaxially rotatably connected, and the clamping cylinder is inserted into the positioning through hole. In the initial state, the positioning notch of the positioning cylinder overlaps with the clamping notch of the clamping cylinder. When the nasogastric tube is clamped and fixed by the positioning component, The positioning notch and the clamping notch are opened, and / or force is applied to the nasofeeding tube to deform the nasofeeding tube, and the nasofeeding tube is moved from the outside of the positioning component through the positioning notch and the clamping notch to the supporting through hole, and the positioning cylinder is rotated so that the positioning notch and the clamping notch do not overlap, thereby completing the fixation of the nasofeeding tube. In this way, even if the nasofeeding tube has a tendency to fall out of the clamping notch due to external force, it will be blocked by the wall of the positioned through hole and cannot fall out; therefore, the nasofeeding tube fixing device provided in this embodiment can ensure the reliable fixation of the nasofeeding tube, prevent the nasofeeding tube from falling out, and the fixing process of the nasofeeding tube is simple and efficient to operate.

[0022] (3) In the improved nasogastric tube fixing device provided by the present application, the positioning assembly also includes a sliding bar, which is slidably connected to the positioning cylinder, and the positioning cylinder is provided with a connecting ring portion, which is provided with a connecting through hole along the transverse direction, and the sliding bar is passed through the connecting through hole; in this way, the positioning cylinder can move along the sliding bar, and the medical staff can adjust the position of the positioning cylinder and the clamping cylinder according to the insertion position of the nasogastric tube, which facilitates the fixation of the nasogastric tube. At the same time, in this embodiment, the sliding bar is also provided with a plurality of protrusions, which abut against the outer wall of the clamping cylinder to limit the clamping cylinder in the transverse direction. In this way, the nasogastric tube fixing device can prevent the positioning cylinder and the clamping cylinder from moving along the sliding bar due to minor facial movements of the patient or minor external forces after the nasogastric tube is fixed, which is conducive to the stable fixation of the nasogastric tube. It should be noted that when the positioning cylinder moves along the sliding bar, medical staff need to apply a certain external force to enable the positioning cylinder to move along the sliding bar; and when the positioning cylinder is no longer subject to the action of the certain external force, such as when the patient's head shakes slightly, the positioning cylinder cannot overcome the force of the protrusion and move on the sliding bar.

[0023] (4) In the improved nasogastric tube fixing device provided in the present application, the positioning component is located in the area between the patient's mouth and nose, namely the philtrum. The nasogastric tube does not need to pass through the patient's mouth area and will not affect the patient's mouth movement during the nasogastric feeding process. The positioning is achieved by connecting the fixing component to the nasal area of the patient's face, and the connection with the patient's head is achieved by the wearing component. The nasogastric tube fixing device is comfortable to wear and easy to use.

[0024] Of course, any product implementing this application does not necessarily need to achieve all of the technical effects described above at the same time.

The fixing assembly 100 can be adjusted and deformed according to the individual facial features of the patient, so that the fixing assembly 100 can fit the patient's face firmly and achieve positioning. After the patient is connected to the patient's head through the wearing assembly 200, even if the patient's head moves, it can ensure that the nasogastric tube fixing device is not easy to change its position significantly on the patient's face. It is firm and stable, which helps to prevent the nasogastric tube from continuing to enter and exit the nasal cavity. The fixing assembly 100 contacts the patient's facial skin in a large and dispersed manner, reducing the pressure of the fixing assembly on the patient's face and improving the user experience. In addition, the fixing assembly 100 has a simple structure and is easy to install. It does not block a large area of the patient's face and will not affect the patient's normal mouth movement, which is conducive to medical staff to observe the patient's face in a timely manner.

[0054] In the nasogastric tube fixing device provided in this embodiment, the positioning component 300 includes a clamping cylinder 330. The nasogastric tube can be fixed to the clamping through hole 331 through the clamping notch 332 to achieve clamping and fixing of the nasogastric tube. However, due to the existence of the clamping notch 332, the nasogastric tube still has the risk of falling out of the clamping through hole 331. For this reason, in this embodiment, the positioning component 300 also includes a positioning cylinder 334. The clamping cylinder 330 and the positioning cylinder 334 are coaxially rotatably connected, and the clamping cylinder 330 is inserted into the positioning through hole 341. In the initial state, the positioning notch 342 of the positioning cylinder 334 overlaps with the clamping notch 332 of the clamping cylinder 330, and the positioning component 300 can be clamped. When fixing the nasofeeding tube, the positioning notch 342 and the clamping notch 332 are opened, and / or force is applied to the nasofeeding tube to deform the nasofeeding tube. The nasofeeding tube moves from the outside of the positioning component 300 through the positioning notch 342 and the clamping notch 332 to the supporting through hole. The positioning cylinder 334 is rotated so that the positioning notch 342 and the clamping notch 332 do not overlap, thereby completing the fixation of the nasofeeding tube. In this way, even if the nasofeeding tube has a tendency to fall out of the clamping notch 332 due to external force, it will be blocked by the wall of the positioned through hole 341 and cannot fall out. Therefore, the nasofeeding tube fixing device provided in this embodiment can ensure the reliable fixation of the nasofeeding tube and prevent the nasofeeding tube from falling out. The fixing process of the nasofeeding tube is simple and efficient to operate.

[0055] In the nasogastric tube fixing device provided in this embodiment, the positioning assembly 300 further includes a sliding bar 320, which is slidably connected to a positioning cylinder 334. The positioning cylinder 334 is provided with a connecting ring portion 343, which is provided with a connecting through hole along a transverse direction, and the sliding bar 320 is inserted into the connecting through hole. In this way, the positioning cylinder 334 can move along the sliding bar 320, and medical personnel can adjust the position of the positioning cylinder 334 and the clamping cylinder 330 according to the insertion position of the nasogastric tube, thereby facilitating the fixation of the nasogastric tube. At the same time, in this embodiment, the sliding bar 320 is also provided with a plurality of raised portions 321, which abut against the outer wall of the clamping cylinder 330 to limit the clamping cylinder 330 in the transverse direction. In this way, the nasogastric tube fixing device can prevent the positioning cylinder 334 and the clamping cylinder 330 from moving along the sliding bar 320 due to minor facial movements of the patient or minor external forces after the nasogastric tube is fixed, thereby facilitating the stable fixation of the nasogastric tube.
