Description

Technical Field

[0001] This utility model relates to the field of medical products, specifically to a nasogastric tube fixing headgear. Background Technology

[0002] A nasogastric tube is a widely used medical device in clinical practice, primarily used to provide enteral nutrition or perform gastrointestinal decompression for patients unable to eat orally. It is typically inserted through the nasal cavity, reaching directly into the stomach to ensure that nutrients or therapeutic fluids are delivered directly into the patient's digestive tract. Proper fixation of the nasogastric tube is crucial for patient comfort, safety, and treatment effectiveness.

[0003] Traditional methods of securing nasogastric tubes primarily rely on medical adhesive tape, which is used to attach the tube to the patient's face, especially on the sides of the nose or cheeks, to ensure stability and prevent slippage or accidental removal. However, for patients requiring long-term nasogastric tube use, the continuous adhesion of the tape often causes skin discomfort, such as redness, itching, and even skin abrasions, significantly impacting their quality of life. Furthermore, as the adhesive strength gradually weakens, the fixation effect of the nasogastric tube diminishes, increasing the risk of accidental removal or displacement.

[0004] To address this issue, Chinese Patent No. CN 221845536 U, entitled "A Nasogastric Tube Fixation Mask," proposes a fixation solution. The device includes a first fixing ring surrounding the nose, and overall stability achieved through a first strap (applying from the forehead, over the ears, and around the back of the head) and a second strap (applying from both cheeks, under the ears, and around the back of the head). Furthermore, the mask incorporates multiple fasteners for securing the nasogastric tube at key points where it enters the body. This design reduces the direct contact area between the mask and the face to some extent, representing an improvement over traditional adhesive tape fixation methods.

[0005] However, the nasogastric tube fixation mask disclosed in the aforementioned patent still has some shortcomings. First, its first fixing ring, first strap, and second strap are quite noticeable on the patient's face, which may cause a strong pulling sensation and discomfort for patients who use nasogastric tubes for a long time. Second, due to the significant differences in the height, width, and length of the nasal bridge among different patients, the first fixing ring of this mask, designed with a uniform size, is difficult to achieve a good fit for different patients, affecting wearing comfort and making it impossible to effectively fix the nasogastric tube. Utility Model Content

[0006] The present invention aims to provide a nasogastric tube fixation headgear to solve the technical problems of poor comfort and ineffective fixation of existing nasogastric tube fixation devices.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a nasogastric tube fixing headgear, comprising a strap and a fixing member for fixing the end of the nasogastric tube that extends into the patient's nose;

[0008] The strap includes a front strap and a back strap. The front end of the front strap is connected to the end of the fastener, and the rear end of the front strap is connected to the back strap. The front strap consists of two sections, located on both sides of the fastener. The back strap forks in front of the patient's ear and converges behind the patient's ear. The front end of the back strap is connected to the rear end of the front strap. The back strap consists of two sections, with the front ends of each section connected to the rear end of the front strap, and the rear ends of the two sections connected to each other. The back strap has adjustable Velcro for adjusting its length.

[0009] The fastener includes an upper arc-shaped lobe and a lower arc-shaped lobe, which are fastened together from both ends. The middle of the upper arc-shaped lobe and the lower arc-shaped lobe are arched outward. The upper arc-shaped lobe and the lower arc-shaped lobe are respectively provided with an insert and an insert groove on the fastening surface. The outer contour of the insert and the groove contour of the insert are consistent. The front end of the front strip is provided with a fixing hole for the insert to pass through.

[0010] The principle and advantages of this solution are as follows: In practical application, only the front band covers the middle of the patient's face, specifically extending from the philtrum to both ends. The front band is connected to the back band in the cheek area. Areas with high facial movement frequency are covered by less band, which can effectively reduce the pulling sensation. The back band is equipped with adjustable Velcro, which can be adjusted according to the patient's head circumference to achieve personalized wearing. This allows the band to fit the head more evenly, reducing the risk of accidental slippage or removal of the nasogastric tube and improving comfort and fixation stability.

[0011] Through the interlocking structure of the upper and lower arc flaps, and the tight fit between the insert and the insert groove, a stable fastening of the fastener is achieved; the front strap is fixed between the interlocking surfaces of the upper and lower arc flaps, making the entire headgear more secure; the curvature of the upper and lower arc flaps can be matched and produced according to the diameter of different nasogastric tubes to ensure effective fixation of the nasogastric tube.

[0012] Before wearing the headgear, thread the fixing holes at the front ends of the two front straps through the inserts of the upper and lower arc-shaped flaps, and tear open the adjustable Velcro on the rear strap. Wrap the two ends of the straps around the patient's face from the back of the head. After the nasogastric tube is inserted into the patient's esophagus, place the upper and lower arc-shaped flaps on both sides of the nasogastric tube at the philtrum and fasten them inwards, inserting the inserts into the insert slots to fix the end of the nasogastric tube closest to the patient's nose. Then, adjust the Velcro according to the size of the patient's face. The operation is simple and quick. Even for patients who are confused and unable to cooperate, this design can ensure the stable fixation of the nasogastric tube, reducing the difficulty of operation and patient discomfort.

[0013] As an improvement, one end of the upper arc petal is provided with an insert, and the other end of the upper arc petal is provided with an insert groove; the distribution of the inserts and insert grooves on the two ends of the lower arc petal matches the insert grooves and inserts of the upper arc petal.

[0014] The structure of the insert includes a cylinder and a cone. The bottom surface of the cylinder is fixedly connected to the end snap-fit ​​surfaces of the upper and lower arc lobes. The top surface of the cylinder is fixedly connected to the bottom surface of the cone. The diameter of the bottom surface of the cone is larger than the diameter of the top surface of the cylinder. The cylinder and the cone are coaxial.

[0015] The beneficial effects of this improvement are as follows: Each end of a single arc-shaped flap is equipped with an insert groove and an insert, which not only enhances the stability of the fixation device and avoids the risk of detachment, but also makes insertion of the fixation device more convenient. The insert adopts a combination structure of cylinder and cone, ensuring a tight fit with the insert groove while facilitating quick insertion and fixation by medical personnel during the wearing process.

[0016] As an improvement, the posterior band includes an upper bifurcated band, a lower bifurcated band, and an auxiliary band. The front ends of the upper bifurcated band and the lower bifurcated band are respectively connected to the rear ends of the front band. The upper bifurcated band runs from the patient's face, over the ear, and around to the back of the patient's head. The lower bifurcated band runs from the patient's face, under the ear, and around to the back of the patient's head. The rear end of the posterior band after the upper bifurcated band and the lower bifurcated band merge is connected to another section of the posterior band at the back of the patient's head.

[0017] The auxiliary band is located at the back of the patient's head, with its two ends connected to the lower bifurcated bands of the two posterior bands.

[0018] The beneficial effects of this improvement are as follows: the auxiliary straps provide cross-fixation, increasing both the stability of the bandage and the contact area between the bandage and the patient's head, reducing pressure on the local skin, protecting the skin, and increasing comfort. Furthermore, the gap between the auxiliary straps and the lower bifurcated straps serves the bony prominence at the back of the head, preventing the bandages from applying pressure to this prominence, protecting the skin, and avoiding discomfort from the occipital protrusion when lying flat. Simultaneously, the auxiliary straps effectively prevent the bandages from slipping during wear, especially when the upper bifurcated straps are not yet glued, where the auxiliary straps play a crucial role in fixation. This design not only improves the stability and comfort of the headgear but also makes the wearing process smoother.

[0019] As an improvement, the adjustable hook and loop fastener is located on the back section of the upper split strap. The upper split strap is divided into two sections at the position of the adjustable hook and loop fastener. The end of one section is fixed with the nap of the adjustable hook and loop fastener, and the end of the other section is fixed with the hook of the adjustable hook and loop fastener. The nap of the adjustable hook and loop fastener is longer than the hook of the adjustable hook and loop fastener.

[0020] The benefits of this improvement are: the adjustable Velcro is located on the back of the ear section of the upper split strap, making length adjustment more flexible and convenient. Medical staff can quickly adjust the strap according to the patient's head circumference to ensure a tight and comfortable fit. This design not only improves the applicability of the headgear but also makes the wearing process more personalized.

[0021] As an improvement, the upper bifurcated strap is provided with an outer tube fixing strap on the preauricular section for fixing the exposed section of the nasogastric tube. The middle section of one side of the outer tube fixing strap is fixed to the upper bifurcated strap, and the two ends of the other side of the outer tube fixing strap are respectively provided with a hook side for fixing Velcro and a rough side.

[0022] The benefits of this improvement are: by securing the exposed portion of the nasogastric tube to the external tube fixing strap, medical staff can ensure the stability of the nasogastric tube during insertion. At the same time, the hook and loop design of the fasteners makes the fixing operation more convenient and improves work efficiency.

[0023] As an improvement, the connection point between the front end of the posterior band and the rear end of the anterior band is located on the outer side of the patient's cheekbone, and the posterior band is wider than the anterior band.

[0024] The benefits of this improvement are: reduced impact of the straps on facial movements. At the same time, the wider rear strap than the front strap allows for more even pressure distribution, improving wearing comfort.

[0025] As an improvement, the fastener includes a polyurethane layer and a silicone layer. The inner arc surfaces of the upper and lower arc lobes and the inner core of the insert are polyurethane layers for providing rigidity support, while the outer arc surfaces of the upper and lower arc lobes and the outer periphery of the insert are silicone layers for providing elastic deformation. The strap is a flat cotton elastic band.

[0026] The beneficial effects of this improvement are as follows: the polyurethane layer provides support for the shape of the upper and lower arc flaps and the insert, enabling the upper and lower arc flaps to securely wrap the nasogastric tube and ensuring that the insert can only be pulled out of the fixing hole under certain force and direction conditions, thus preventing the nasogastric tube from accidentally falling off; the silicone layer is soft and elastic, improving the comfort of the upper and lower arc flaps in contact with the skin; the silicone layer also gives the insert a certain elastic deformation, so that the insert and fixing hole will not undergo plastic deformation when the insert is inserted or pulled out, enabling the reuse of the fixing headgear, and the silicone layer of the upper and lower arc flaps has greater friction with the nasogastric tube, preventing the nasogastric tube from sliding.

[0027] The use of flat cotton elastic bands as the strap material is more skin-friendly and conforms better to the face, improving patient comfort. This material choice not only extends the lifespan of the headgear but also enhances the patient's wearing experience.

[0028] As an improvement, the width of the front strip is 0.5 cm.

[0029] The benefits of this improvement are that it ensures sufficient strength to support the weight of the fixation device and the nasogastric tube while reducing pressure on the face. This width also makes the headgear more comfortable and stable to wear. Attached Figure Description

[0036] Example

[0037] The basics are as follows: Figure 1 and attached Figure 2 As shown, a nasogastric tube fixing headgear includes a strap and a fixing member 1;

[0038] The straps include a front strap 2 and a rear strap. The front end of the front strap 2 is connected to the fastener 1, and the rear end of the front strap 2 is connected to the rear strap. The front strap 2 consists of two sections, located on both sides of the fastener 1.

[0039] The posterior band forks in front of the patient's ear and converges behind the ear. The connection point between the front end of the posterior band and the rear end of the anterior band 2 is located on the outer side of the patient's cheekbone. The posterior band consists of two segments, with the front ends of each segment connecting to the rear end of the anterior band 2, and the rear ends of the two segments connecting to each other.

[0040] As attached Figure 3As shown, the posterior band includes an upper bifurcation band 3 and a lower bifurcation band 4. The front ends of the upper bifurcation band 3 and the lower bifurcation band 4 are connected to the rear ends of the front band 2, respectively. The upper bifurcation band 3 runs from the patient's face, over the ear, and around to the back of the patient's head. The lower bifurcation band 4 runs from the patient's face, under the ear, and around to the back of the patient's head. The rear end of the posterior band, where the upper bifurcation band 3 and the lower bifurcation band 4 meet, connects to another posterior band at the back of the patient's head. The two ends of the posterior band connect at the back of the patient's head in the shape of an infinity symbol, i.e., a horizontal number "8".

[0041] The upper bifurcated strap 3 is provided with an adjusting hook and loop fastener 6 for adjusting the length of the upper bifurcated strap 3, and the adjusting hook and loop fastener 6 is located on the back section of the upper bifurcated strap 3. The upper bifurcated strap 3 is divided into two sections at the position of the adjusting hook and loop fastener 6. The end of one section is fixed with the nap of the adjusting hook and loop fastener 6, and the end of the other section is fixed with the hook of the adjusting hook and loop fastener 6. The nap of the adjusting hook and loop fastener 6 is longer than the hook of the adjusting hook and loop fastener 6.

[0042] The posterior band also includes an auxiliary band 5, which is located at the back of the patient's head. The two ends of the auxiliary band 5 are connected to the lower bifurcation bands 4 of the two posterior bands respectively.

[0043] The upper bifurcated strap 3 has an outer tube fixing strap 7 on the anterior part of the ear, which is used to fix one side of the exposed end of the nasogastric tube 13. The middle section of one side of the outer tube fixing strap 7 is fixed to the upper bifurcated strap 3, and the two ends of the other side of the outer tube fixing strap 7 are respectively provided with a hook side and a loop side for fixing Velcro.

[0044] The fastener 1 is positioned below the patient's nose during wear and is used to secure the end of the nasogastric tube 13 that extends into the patient's nose. (See attached image) Figure 4 As shown, the fixing member 1 includes an upper arc-shaped flap 11 and a lower arc-shaped flap 12, which are fastened together from both ends. The middle part of the upper arc-shaped flap 11 and the lower arc-shaped flap 12 arches outward. The gap in the middle of the upper arc-shaped flap 11 and the lower arc-shaped flap 12 after fastening is used to accommodate and fix the nasogastric tube 13.

[0045] Both ends of the upper arc petal 11 and the lower arc petal 12 are provided with fastening components for engagement. The fastening components include an insert 8 and an insert groove 9. The outer contour of the insert 8 and the groove contour of the insert groove 9 are consistent, so that the two can fit tightly together to achieve fastening and fixation. The insert 8 is located on the inner side of one end of the upper arc petal 11, and the insert groove 9 is located on the inner side of the other end of the upper arc petal 11. The distribution of the insert 8 and the insert groove 9 on the inner sides of both ends of the lower arc petal 12 matches that of the upper arc petal 11. This makes the upper arc petal 11 and the lower arc petal 12 mutually fastened.

[0046] The structure of the insert 8 includes a cylinder and a cone. The bottom surface of the cylinder is fixedly connected to the inner side of the end face of the upper arc lobe 11 and the lower arc lobe 12. The top surface of the cylinder is fixedly connected to the bottom surface of the cone. The diameter of the bottom surface of the cone is larger than the diameter of the top surface of the cylinder. The cylinder and the cone are coaxial.

[0047] The front end of the front splitter 2 is provided with a fixing hole 10. The insert 8 passes through the fixing hole 10 and then extends into the insert groove 9. This fixes the front splitter 2 between the upper arc petal 11 and the lower arc petal 12.

[0048] The upper arc petal 11, lower arc petal 12 and insert 8 of the fastener 1 are all made of double-layer material. The inner arc surface of the upper arc petal 11 and lower arc petal 12 and the inner core of the insert 8 are polyurethane layers for providing hardness support, and the outer arc surface of the upper arc petal 11 and lower arc petal 12 and the outer periphery of the insert 8 are silicone layers for providing elastic deformation.

[0049] The polyurethane layer provides support for the shape of the upper and lower arc flaps and the insert, allowing the upper and lower arc flaps to securely wrap the nasogastric tube and ensuring that the insert can only be pulled out of the fixing hole under certain force and direction conditions, thus preventing accidental dislodgement of the nasogastric tube. The silicone layer is soft and elastic to improve the comfort of the upper and lower arc flaps in contact with the skin. The silicone layer also gives the insert a certain elastic deformation, so that the insert and fixing hole will not undergo plastic deformation when inserted or pulled out, enabling the reuse of the fixing headgear.

[0050] The front split band 2 is a flat cotton elastic band 0.5cm wide and approximately 5cm long. The lower split band 4 is a flat cotton elastic band 15cm long. The rear split band is wider than the front split band 2.

[0051] The specific wearing process is as follows:

[0052] Before wearing a nasogastric tube 13 fixation headgear, the fixing holes 10 at the front ends of the two front strips 2 are passed through the inserts 8 of the upper arc flap 11 and the lower arc flap 12, and the adjustment Velcro 6 of the upper forked strip 3 is torn open. The two ends of the straps are then wrapped around the patient's face from the back of the head on both sides.

[0053] Once the nasogastric tube 13 has been inserted into the patient's esophagus, the upper arc flap 11 and lower arc flap 12 are fastened inwards from both sides of the nasogastric tube 13 at the patient's philtrum, i.e., the insert 8 is inserted into the insert groove 9 to fix the end of the nasogastric tube 13 closest to the end that extends into the patient's nose. Then, adjust the Velcro 6 according to the size of the patient's face. Finally, wrap the exposed end of the nasogastric tube 13 in a "U" shape and tightly attach it to the middle section of the side of the outer tube fixing strap 7 with the fixing Velcro. The two ends of the outer tube fixing strap 7 encircle the nasogastric tube 13 and are glued to fix the exposed end of the nasogastric tube 13.

[0054] When the nasogastric tube 13 is located in the patient's left nasal cavity, the exposed end of the nasogastric tube 13 is fixed to the left outer tube fixing band 7.
