Description

Technical Field

[0001] This utility model belongs to the technical field of gastric tube fixation devices, and in particular relates to an oral feeding tube fixation device. Background Technology

[0002] In existing technologies, intermittent nasogastric feeding, as a novel nutritional support method, is increasingly being used for patients with swallowing dysfunction but still retaining gastrointestinal function due to various causes (such as hemiplegia after stroke, laryngeal tumor resection, maxillofacial surgery, etc.). The core of this method lies in its "intermittent" nature—that is, during each meal, a nasogastric tube is inserted into the esophagus and stomach via oral or nasal route, and immediately removed after the nutrients are delivered, in order to simulate the normal eating process as closely as possible. This satisfies the patient's nutritional needs while helping to maintain their physiological and psychological well-being. However, in clinical application, how to ensure the stability of the intubation while simultaneously considering patient comfort and ease of operation remains a significant challenge.

[0003] First, after the insertion depth has been confirmed and the nasogastric tube is in place, current techniques typically rely on the patient holding the tube in their mouth or having someone else hold it to assist with feeding to secure the tube. When the patient holds the tube in their mouth, they often need to bite down hard to prevent it from slipping out, leading to prolonged tension on the perilip and oral mucosa, which can cause discomfort such as lacerations at the corners of the mouth and lip muscle spasms. For patients who are still conscious but have limited movement in some limbs, prolonged tube holding can cause fatigue, drooling, or confusion, severely affecting feeding effectiveness and postoperative recovery. If someone else holds the tube to assist with feeding, the patient loses the ability to feed independently, which is detrimental to the recovery of their daily living self-care level. It also significantly increases the workload of caregivers or family members, especially in cases requiring long-term, frequent feedings. The procedure is cumbersome and prone to errors in insertion depth or tube displacement due to human factors.

[0004] Second: Clinically, there are various materials used for tube insertion, including specialized nasogastric tubes, ordinary suction catheters, or even urinary catheters. Among them, suction catheters and urinary catheters usually lack graduation markings, making it impossible to visually determine the insertion depth. Even if the nasogastric tube itself has graduations, the graduations are often obscured or worn due to limited visibility in the oral cavity and the adhesion of saliva and mucous membranes, making them difficult to identify. This requires re-measurement or estimation based on experience before each feeding, which is time-consuming and prone to measurement errors that could cause the tube tip to enter the lower esophagus or remain too shallowly, leading to the risk of aspiration or reflux of nutrients, posing a potential threat to patient safety.

[0005] Furthermore, existing patent documents concerning gastric tube fixation devices, such as CN114832208A and CN114099885A, primarily focus on the design of attaching and supporting the tube in the nasal cavity or facial area. These solutions generally employ adhesive tape, fixing straps, or complex external mechanical structures to enhance stability by improving the fit between the tube and facial skin, but often neglect the special needs of intermittent oral feeding. On the one hand, long-term use of external adhesives can easily cause skin allergies, pressure injuries, or tape residue; on the other hand, mechanical locking structures designed to ensure stability are mostly bulky and complex to operate, increasing the learning costs for medical staff and patients, and significantly raising product manufacturing and usage costs, making it difficult to balance economy and ease of use in large-scale clinical deployment.

[0006] Therefore, a mature, simple, and comfortable technical solution for intermittent oral-nasal feeding in terms of tube fixation and patient self-feeding has not yet been developed. Existing patents mostly improve nasal or facial fixation methods, failing to effectively address the discomfort and inconvenience caused by the patient holding the tube in their mouth or requiring assistance from others, and also failing to provide targeted improvements to address the problem of difficult-to-read scales. Thus, developing an oral feeding tube fixation device that can accurately fix the tube depth, free the patient's hands for self-feeding, and also features clear scales, ease of operation, and high comfort has significant clinical value and widespread application implications. Utility Model Content

[0007] This invention aims to solve the technical problems of existing fixation methods in intermittent oral-nasal feeding, which rely on the patient's mouth or assistance, leading to patient discomfort, affecting independent feeding ability, increasing the burden on caregivers, and difficulties in distinguishing the tube markings, the existing fixation device design not taking into account the needs of intermittent oral feeding, easily causing skin problems, and being complex and costly to operate. It provides an oral feeding tube fixation device that improves the patient's ADL (Activities of Daily Living), achieves the goal of rehabilitation care, and is also easy for elderly caregivers to operate, making the tube insertion operation simple and quick.

[0008] In view of this, the present invention provides a feeding tube fixing device, comprising:

[0009] The mouthpiece has a first connecting opening in its middle part;

[0010] A cannula sleeve, one end of which is connected to the first communication port, is used to guide the cannula to be inserted through the mouth;

[0011] The pipe fixing plate and the pipe fixing component disposed thereon are provided. The pipe fixing plate and the nozzle fitting are integrally formed. The pipe fixing component is used to lock the insertion tube after confirming that the insertion tube has reached the predetermined depth.

[0012] A head fixation device, disposed on the mouth fitting, is used to detachably fix the mouth fitting to the patient's head.

[0013] In one example of this application, the mouth fitting includes a cover plate and a flexible outer edge plate formed by folding along its outer periphery, and the pipe fixing plate is integrally formed on the outer edge plate.

[0014] In one example of this application, the cannula sleeve is integrally formed with the mouthpiece, and the diameter of the insertion channel port at the end of the cannula sleeve away from the mouthpiece is slightly smaller than the diameter of the cannula.

[0015] In one example of this application, the cannula includes a lip-fitting portion, which has a tapered, trumpet-shaped design with a gradually narrowing cross-section from the side near the mouth fitting to the side away from the mouth fitting. An insertion channel is provided on the inner side of the lip-fitting portion, and the insertion channel communicates with the first communication port.

[0016] In one example of this application, the pipe fixing plate includes a first fixing plate body and an arc-shaped connecting part. The arc-shaped connecting part is used for the arc-shaped transition connection between the pipe fixing plate and the outer eaves plate. The first fixing plate body is designed in an inclined shape, and the pipe fixing component is disposed on the first fixing plate body.

[0017] In one example of this application, the plane containing the first fixing plate forms an acute angle of 30° to 60° with the plane containing the covering plate.

[0018] In one example of this application, the pipe fastener includes an arc-shaped clamping plate body, which is integrally formed with the pipe fixing plate, and a first opening groove is provided on the arc-shaped clamping plate body.

[0019] In one example of this application, a locking adjustment member is provided on the arc-shaped clamping plate body, which can adjust the clamping gap inside the arc-shaped clamping plate body.

[0020] In one example of this application, a connecting ear plate is provided on each side of the cover plate along its length, and a first connecting port is provided on the connecting ear plate for fixing the head fastener.

[0021] In one example of this application, the head fixing member includes a first clamping member and a second clamping member. One end of the first clamping member is connected to a first connection port on one of the connecting ear plates, and one end of the second clamping member is connected to a first connection port on a second connecting ear plate. A second opening groove is formed between the first clamping member and the second clamping member.

[0038] like Figures 1-6 As shown, this application discloses a feeding tube fixing device, comprising:

[0039] The mouthpiece 1 has a first connecting port 103 in its middle part;

[0040] The insertion sleeve 2 has one end connected to the first communication port 103, which is used to guide the insertion of the insertion tube through the mouth;

[0041] The pipe fixing component 4 is disposed on the pipe fixing plate 3 which is integrally connected with the mouth fitting component 1, and is used to lock the insertion tube after confirming that the insertion tube has been inserted to a predetermined depth.

[0042] The head fixation component 5 is disposed on the mouth fitting component 1 and is used to detachably fix the mouth fitting component 1 to the patient's head.

[0043] This application discloses an oral feeding tube fixing device, which mainly consists of a mouth fitting 1, an insertion sleeve 2, and a tube fixing component 4. The mouth fitting 1 is made of soft medical-grade silicone material and is processed into a fitting surface that conforms to the contour of the oral cavity. A first connecting port 103 is opened near the center for docking and connecting with the insertion sleeve 2. The insertion sleeve 2 is also made of soft material and has a rounded guide shape at the front end to simulate the structure of a nipple. This can smoothly guide the gastric tube (insertion tube) to enter smoothly and disperse the pressure on the lips, ensuring that the insertion tube can be inserted smoothly and accurately through the mouth. In addition, a detachable head fixing component 5 is provided on the mouth fitting 1. The head fixing component 5 securely fixes the mouth fitting 1 to the patient's head by means of a strap, a snap, or an ear loop. The oral feeding tube fixing device described in this application forms a stable support point by tightly fitting the mouthpiece 1 to the patient's mouth. The insertion sleeve 2 guides the tube through the mouth to the predetermined depth. After medical staff confirm the depth by observing the insertion tube scale or using auxiliary positioning tools, they press and snap the tube portion extending from the insertion sleeve 2 onto the tube fixing component 4 to complete the tube locking. At this time, the tube is firmly fixed to the tube fixing component 4 and cannot move. The head fixing component 5 adopts a Velcro strap, elastic strap, or elastic buckle headband design, which can be freely adjusted according to different head shapes and tightly cooperates with the mouthpiece 1 to form a two-point fixation to resist the pulling force generated by the patient's head movement. During feeding, the patient can eat freely without biting hard or being supported by others. The entire device has a compact structure, can be disassembled as a whole for easy cleaning and disinfection, and also has a disposable or reusable mode to meet different clinical nursing needs.

[0044] The oral feeding tube fixing device described in this application features a dual design of mouthpiece 1 and insertion sleeve 2, which reduces oral pressure while ensuring smooth tube insertion. The tube fixing component 4 on the mouthpiece 1 utilizes a slot-type locking mechanism to achieve precise control and stable locking of the insertion depth. Combined with the head fixing component 5, this forms a dual fixing method, freeing the patient's hands, significantly improving independent feeding ability, and effectively preventing tube displacement during patient head movement. The device is simple to operate, allowing insertion and locking to be completed with one hand, greatly reducing nursing difficulty and labor costs. Furthermore, the detachable modular design facilitates cleaning and disinfection while reducing the risk of cross-infection. Its lightweight design and ergonomic shape enhance wearing comfort, making it particularly suitable for elderly patients, children, and patients with functional limitations requiring frequent feeding over long periods.

[0045] As a preferred example of this application, the cannula sleeve 2 includes a lip-fitting portion 201, which has a gradually narrowing cross-section and a trumpet shape from the side close to the mouth fitting 1 to the side away from the mouth fitting 1. An insertion channel 202 is provided on the inner side of the lip-fitting portion 201, and the insertion channel 202 communicates with the first communication port 103. In the example of this application, the insertion sleeve 2 is optimized by gradually narrowing from the side near the mouth fitting 1 towards the side away from the mouth fitting 1, forming a trumpet-shaped structure with a gradually narrowing cross-section. The overall shape resembles a pacifier. The lip fitting part 201 is integrally molded from skin-friendly medical-grade silicone material. This design not only conforms to ergonomic principles but also closely fits the patient's perilip and oral cavity contours, dispersing local pressure. The inner side of the lip fitting part 201 has an insertion channel 202 of appropriate diameter. This channel seamlessly connects to the first connecting port 103 on the mouth fitting 1, forming a smooth guiding path. This allows the insertion tube to gradually adapt to and conform to the contours of the patient's lips during insertion, reducing resistance and discomfort while maintaining stable support for the insertion tube. Furthermore, the trumpet-shaped design at both ends of the insertion channel 202 allows it to be compatible with various sizes of gastric tubes without affecting its flexibility.

[0046] The insertion sleeve 2 of this application combines the skin-friendly fit of the lip fitting part 201 with the smooth guidance of the insertion channel 202, which not only greatly reduces the pressure and friction on the lips and oral mucosa during insertion, but also ensures smooth insertion and stable support of the tube body by the reasonable diameter and smooth inner wall design of the insertion channel.

[0047] As a preferred example of this application, the cannula sleeve 2 and the mouthpiece fitting 1 are integrally formed. The diameter of the port of the insertion channel 202 on the cannula sleeve 2, which is furthest from the mouthpiece fitting 1, is slightly smaller than the diameter of the cannula. In this example, the cannula sleeve 2 and the mouthpiece fitting 1 are integrally formed in medical silicone material to enhance structural strength and prevent loosening or leakage between components. The insertion channel 202 on the cannula sleeve 2 gradually converges from the mouthpiece fitting 1 to the distal end to form a micro-flare structure, making the port diameter slightly smaller than the outer diameter of the cannula. This helps to generate controllable elastic resistance during cannulation, so as to achieve a tight seal at the insertion point of the tube through slight elastic deformation. This ensures the smoothness of the cannulation process and improves the safety and hygiene of the feeding process.

[0048] As a preferred example of this application, the mouth fitting 1 includes a cover plate 101, with an outer rim plate 102 formed by folding the outer periphery of the cover plate 101. The pipe fixing plate 3 is integrally disposed on the outer rim plate 102. In the example of this application, the mouth fitting 1 is integrally formed by the cover plate 101 and the folded outer rim plate 102. The cover plate 101 is generally oblong in shape to fit closely to the contour of the patient's mouth and provide uniform support. The outer rim plate 102 is folded outward along the outer periphery of the cover plate 101 to form a flexible covering edge, and is also used to connect the pipe fixing plate 3. This makes the connection between the pipe fixing member 4 and the mouth fitting 1 more stable, simplifies the device structure, and improves the ease of use.

[0049] As a preferred example of this application, the pipe fixing plate 3 includes a first fixing plate body 301 and an arc-shaped connecting part 302. The arc-shaped connecting part 302 is used for the arc-shaped transition connection between the pipe fixing plate 3 and the outer eaves plate 102. The first fixing plate body 301 is designed in an inclined shape, and the pipe fixing member 4 is disposed on the first fixing plate body 301. In the example of this application, the pipe fixing plate 3 achieves a smooth transition by integrally forming the arc-shaped connecting part 302 with the folded outer eaves plate 102, avoiding stress concentration caused by structural abrupt changes, and making the entire structure more rounded and smooth, avoiding discomfort or damage to the patient's skin caused by sharp edges and corners. An inclined first fixing plate body 301 is provided at the end of the arc-shaped connecting part 302 away from the outer eaves plate 102, providing a stable and suitable installation platform for the pipe fixing member 4. When the intubation tube needs to be fixed, medical staff place it on the tube fixation component 4. Due to the inclined design of the first fixation plate 301, the intubation tube can be fixed in a natural and stable posture, which will not cause damage due to excessive bending or displacement due to insecure fixation. The arc-shaped connection part 302 ensures the smoothness and continuity of the entire fixation process, avoiding the risk of stress concentration or damage caused by structural abrupt changes.

[0050] As a preferred example of this application, the acute angle between the plane of the first fixing plate 301 and the plane of the covering plate 101 is 30° to 60°. In the example of the application, by bending the first fixing plate 301 outward relative to the covering plate 101 at a preferred angle of 120° to 150°, it is possible to ensure that the insertion tube maintains a natural and stable bending angle when fixed, reducing the risk of tube wall damage or blockage caused by excessive bending, and avoiding the problem of unstable fixing and easy slippage of the insertion tube due to excessive angle. The tube fixing member 4 is firmly installed on the first fixing plate 301, and its position and tilt angle are matched to provide a reliable and comfortable fixing point for the insertion tube, ensuring that the insertion tube remains stable during feeding.

[0051] As a preferred example of this application, the pipe fastener 4 includes an arc-shaped clamping plate body 401, which is integrally formed with the pipe fixing plate 3, and a first opening groove 402 is provided on the arc-shaped clamping plate body 401. In the example of this application, the pipe fixing component 4 is seamlessly connected to the pipe fixing plate 3 through an integral molding process to form an arc-shaped clamping plate body 401. This not only enhances the connection strength between the two but also simplifies the manufacturing process and improves production efficiency. The arc-shaped structure of the arc-shaped clamping plate body 401 can better fit the outer wall of the insertion tube, providing uniform support and reducing deformation or damage to the insertion tube caused by improper fixing. Combined with the first opening groove 402 provided on the arc-shaped clamping plate body 401, which is preferably located on the upper side of the arc-shaped clamping plate body 401 away from the first fixing plate 301, or it can be located on the left and right sides of the arc-shaped clamping plate body 401 in the insertion direction, by optimizing the groove width and groove depth of the first opening groove 402, the insertion tube can be easily inserted and closely fitted to the outer wall of the arc-shaped clamping plate body 401, while still retaining enough space to ensure the flow of nutrient solution. This ensures both the reliability of the insertion tube fixation and the patient's comfort. This structure can complete the fixation without additional moving parts, and the integrated design reduces the number of parts, simplifying the production and cleaning process.

[0052] As a preferred example of this application, a locking adjustment component 403 is provided on the arc-shaped clamping plate body 401. The locking adjustment component 403 can adjust the clamping gap inside the arc-shaped clamping plate body 401. In the example of this application, by adding a locking adjustment component 403 to the arc-shaped clamping plate body 401 on the pipe fixing component 4, the integrally formed arc-shaped clamping plate body 401 has both support and clamping functions. Its body extends along the setting direction of the pipe fixing plate 3 to form an arc-shaped clamping groove structure that conforms to the curve of the outer wall of the pipe. The locking adjustment component 403 is embedded in the fitting position of the arc-shaped clamping plate body 401. When medical staff or patients gently rotate or slide the locking adjustment component 403 according to the pipe diameter and the needs of the usage environment, its internal micro-mechanical structure or elastic component can push to slightly tighten or loosen, thereby accurately adjusting the size of the arc-shaped clamping space, ensuring that the pipe can not move firmly, but will not affect the infusion flow or damage the pipe body due to excessive compression. Moreover, users can adapt different specifications of cannulas without replacing parts. In the example of this application, the locking adjustment component 403 includes an adjusting lock head 4031, a first locking plate 4032, and a second locking plate 4033. The first locking plate 4032 and the second locking plate 4033 are elastically disposed at an angle inside the arc-shaped plate body 401, and their connecting ends extend out of the arc-shaped plate body 401 and are threadedly connected to the adjusting lock head 4031. By rotating the adjusting lock head 4031, the connecting ends of the first locking plate 4032 and the second locking plate 4033 slide outward or inward, thereby adjusting the opening and closing size of the first locking plate 4032 and the second locking plate 4033. The locking adjustment component 403 described in this application utilizes the transmission characteristics of the threaded connection and the elastic setting of the first locking plate 4032 and the second locking plate 4033 to adjust the arc-shaped clamping space. When the adjusting lock head 4031 is rotated, since the connection end of the adjusting lock head 4031 with the first locking plate 4032 and the second locking plate 4033 is threaded and the connection end is limited by the stop limiting structure (not shown in the figure), it can only slide to the inside or outside of the arc-shaped clamping plate body 401 under the rotation of the adjusting lock head 4031. If the adjusting lock head 4031 rotates in one direction, the connection end slides outward, and the opening and closing degree of the first locking plate 4032 and the second locking plate 4033 increases due to the elastic effect, and the arc-shaped clamping space becomes larger. If it rotates in the opposite direction, the connection end slides inward, and the opening and closing degree of the first locking plate 4032 and the second locking plate 4033 decreases, and the arc-shaped clamping space becomes smaller. Thus, the fixing force and space can be precisely adjusted according to the thickness of the insertion tube.

[0053] As a preferred example of this application, a connecting ear plate 104 is provided on each side of the cover plate 101 along its length, and a first connecting port 105 is provided on the connecting ear plate 104 for fixing the head fixing member 5. In the example of this application, the two connecting ear plates 104 are integrally formed on the outer edge plate 102 along the length of the cover plate 101, and the pipe fixing plate 3 is provided on the outer edge plate 102 along the width of the cover plate 101. Preferably, the pipe fixing plate 3 is provided on the outer edge plate 102 below the cover plate 101, and an arc-shaped relief portion is provided above the cover plate 101, so that it can better fit the contour of the patient's head, improve the patient's wearing comfort, and avoid pressure or discomfort to the patient's nose due to unreasonable structure.

[0054] As a preferred example of this application, the head fixing member 5 includes a first clamping member 501 and a second clamping member 502. One end of the first clamping member 501 is connected to a first connection port 105 on a connecting ear plate 104, and one end of the second clamping member 502 is connected to a first connection port 105 on a second connecting ear plate 104. A second opening groove 503 is formed between the first clamping member 501 and the second clamping member 502. In the example of this application, the head fixing member 5 consists of two detachable clamping members, namely a first clamping member 501 and a second clamping member 502. The first clamping member 501 and the second clamping member 502 are respectively installed on the first connecting ports 105 on the connecting ear plates 104 on both sides of the cover plate 101 by detachable pins or buckles. After the two are connected, a second opening groove 503 is naturally formed in the middle area away from the connecting end. The second opening groove 503 together with the cover plate 101 constitutes a head-mounted frame structure. When the patient wears it, he only needs to gently put his head into this frame. Through the cooperation between the clamping members and the ear plates and the covering of the back of the head by the groove, the device is stably restrained. This structure has a certain degree of elasticity while maintaining firm fixation, which is convenient for medical staff to quickly install and remove, and no additional straps or adhesive materials are required. The operation is simple and quick.

[0055] The oral feeding tube fixing device described in this application forms a stable support point by tightly fitting the mouthpiece 1 to the patient's mouth. The insertion sleeve 2 guides the tube to be inserted smoothly and accurately through the mouth to the predetermined depth. The slot-type locking mechanism of the tube fixing component achieves precise control and stable locking of the insertion depth. Combined with the head fixing component, a dual fixing method is formed. This reduces oral pressure and reduces pressure and friction on the lips and oral mucosa during insertion, while ensuring smooth insertion of the tube and maintaining stable support. It is simple to operate, has a compact structure, and its detachable modular design facilitates cleaning and disinfection, reducing the risk of cross-infection. The overall lightweight and ergonomic shape enhance wearing comfort. It provides a safe, convenient, and economical solution for long-term, intermittent oral-nasal feeding, with the advantages of low cost, fast speed, ease of use, enabling patients to feed themselves and improving their self-care ability.

[0056] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
