Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to a nasogastric tube fixation device. Background Technology

[0002] In the field of medical care, providing appropriate nutritional support is crucial for maintaining vital signs and promoting recovery for patients who are unable to eat normally orally for various reasons, such as impaired consciousness, dysphagia, or digestive system dysfunction. Nasogastric tube feeding, as an important method of enteral nutrition support, involves inserting a thin, flexible tube through the nasal cavity, passing through the pharynx and esophagus, and finally reaching the stomach or small intestine to deliver liquid food, medications, or fluids. This technique not only effectively ensures the patient's nutritional intake and avoids complications such as malnutrition and electrolyte imbalance, but also reduces the risk of infection and vascular damage that may result from long-term intravenous infusion.

[0003] However, traditional methods of nasogastric tube fixation have significant drawbacks. Current technology uses adhesive tape to fix the tube across the nostrils in a crisscross pattern. This method is ineffective, as the tube easily shifts during daily activities. Furthermore, prolonged use of adhesive tape can cause numerous adverse effects on the skin of the nostrils. The tape's stickiness continuously irritates the skin, which is sensitive and fragile, easily breaking after prolonged pressure and friction. Once the skin is broken, patients experience pain and discomfort, significantly increasing the risk of infection. Moreover, over time, the tape's adhesiveness decreases after contact with skin secretions and sweat, further weakening its fixation effect and requiring frequent tape changes. This not only increases the workload of caregivers but also risks further damaging the already compromised skin, creating a vicious cycle that greatly hinders the patient's treatment and recovery. Therefore, a nasogastric tube fixation device is urgently needed to address these problems. Utility Model Content

[0004] This device provides a nasogastric tube fixator, the specific implementation of which is as follows:

[0005] A nasogastric tube fixation device, comprising:

[0006] The binding rope and the fixing component on the binding rope for positioning the nasogastric tube are connected at both ends by a limiting buckle, and the fixing component is installed in a headband style by the binding rope.

[0007] The fixing assembly includes a positioning bracket and an actuator arranged in parallel. The actuator consists of a second fixing post and a deformation ring at its end. The positioning bracket has a first fixing post arranged in parallel with the second fixing post. A snap-fit ​​channel for inserting the end of the deformation ring is provided between the second fixing post and the first fixing post. The deformation ring and the snap-fit ​​channel are directly provided with a snap-fit ​​part. The vertical clamping and limiting of the nasogastric tube by the fixing assembly is achieved by the two snapping together.

[0008] Based on the above technical solutions, the vertical positioning of the nasogastric tube is achieved by using binding ropes and fixing components. This not only greatly improves the stability of the nasogastric tube during use, but also eliminates many drawbacks of traditional adhesive tape installation. This installation method not only makes the positioning of the nasogastric tube more durable and effectively avoids the problem of nasogastric tube displacement caused by tape falling off or weakening of adhesion, but also greatly reduces the discomfort of patients during use. It also avoids the adverse reactions such as irritation, redness, swelling or even allergies that may be caused by prolonged tape application to human skin, thus ensuring the comfort and safety of patients when receiving nasogastric feeding treatment.

[0009] Preferably, the back of the deformation ring is provided with an integrated paddle.

[0010] Preferably, the deformation ring has a barb at its end, and the first fixing post has a positioning plate at its end that engages with the barb.

[0011] Preferably, the middle section of the first fixing post has a positioning protrusion on the side facing the second fixing post, and the positioning protrusion also engages with the barb.

[0012] Based on the above technical solution, the positioning protrusion and positioning plate structure realizes the two-stage locking adjustment of the barb at the end of the deformation ring, which not only enhances the firmness of the locking, but also allows for precise control of the pre-tightening force of the deformation ring; according to the patient's specific needs and comfort, the clamping degree of the nasogastric tube can be flexibly adjusted to ensure a stable connection of the nasogastric tube.

[0013] Preferably, the binding rope and the fixing component are connected by a base, and the back of the base is designed to conform to the arcuate contour of the upper lip of the human body.

[0014] Preferably, the binding rope is provided on both sides of the positioning bracket as a first rope body and a second rope body, and the limiting buckle is provided at the end of the first rope body.

[0015] Preferably, the upper and lower ends of the base are respectively provided with V-shaped grooves that conform to the columella of the human nose.

[0016] Based on the above technical solutions, by setting a V-shaped groove, the columella of the human nose can be used to achieve horizontal limitation of the positioning card seat, preventing it from shifting to the left or right during application. When we set V-shaped grooves on both the upper and lower parts of the positioning card seat, it can be compatible with and adapted to nasogastric tubes in the left and right nostrils. By being upright or inverted, it can provide a stable and reliable fixation effect regardless of the position of the patient's nostrils, effectively enhancing the versatility of the product.

[0017] Preferably, multiple fixing components can be vertically installed on the base, and there are two ways to arrange them:

[0018] Firstly, the base is equipped with several positioning brackets and several actuators along the vertical direction, and the positioning brackets and actuators correspond one-to-one.

[0019] Secondly, the base is provided with a single positioning bracket and several actuators along the vertical direction, and the total thickness of each actuator is less than the thickness of the positioning bracket.

[0020] Based on the above technical solutions, by using two or more fixing components, the stability of the nasogastric tube in the vertical upper limit position can be significantly improved, further enhancing the safety and reliability of the entire nasogastric feeding system.

[0021] Preferably, a sliding block for horizontal adjustment is provided between the fixing component and the base. A sliding groove is provided on the base, the sliding block is slidably disposed in the sliding groove, and a locking key acting inward on the sliding block is provided outside the sliding groove.

[0022] Based on the above technical solution, by integrating the functions of the sliding block and the locking button, the horizontal position of the fixing component can be flexibly adjusted after the nasogastric tube is secured. This not only gives users the ability to fine-tune according to individual needs but also significantly improves the comfort and adaptability of the fixing component to the human nose. Users can easily adjust the position of the fixing component using the sliding block according to their own comfort level, and then use the locking button to securely lock it, thereby ensuring that the nasogastric tube remains effectively fixed while minimizing pressure on the nose and improving overall wearing comfort.

[0023] In summary, this application includes the following beneficial technical effects:

[0024] 1. This utility model achieves vertical positioning of the nasogastric tube through binding rope and fixing components, and its headband installation method eliminates the drawbacks of adhesive tape, making the positioning of the nasogastric tube durable and less likely to cause discomfort to the human skin.

[0025] 2. This utility model uses a V-shaped groove to limit the horizontal movement of the positioning card holder by means of the human nasal columella, preventing it from shifting to the left or right during application;

[0026] 3. This utility model has a simple structure. By vertically setting two or more fixing components, the stability of the nasogastric tube in vertical positioning can be improved.

[0027] 4. By setting a sliding block and a locking key, this utility model can adjust the horizontal position of the fixing component after the nasogastric tube is fixed, thereby enhancing the adjustment of the positioning comfort of the human nose after the fixing component is installed.
