Description

Technical Field

[0001] The utility model relates to the technical field of gastrointestinal pipeline positioning tools, in particular to an ear-hook type dual-purpose transnasal gastrointestinal pipeline secondary fixing device. Background Art

[0002] After gastric surgery, patients usually need to have two tubes, a gastrointestinal decompression tube and a sac jejunal catheter, placed in place for postoperative drainage and enteral nutrition therapy. However, the fixation method of these tubes becomes an important consideration during the long-term retention of these tubes. At present, the more commonly used secondary fixation method in clinical practice is to fix the tube to the patient's face using a 3M tape high-lift platform method. However, this fixation method has many disadvantages in practical applications.

[0003] First, due to the vigorous secretion of the sebaceous glands in the cheeks, sweat can easily make the tape lose its stickiness. If it is not discovered and replaced in time, the patient may scratch due to the discomfort caused by the tape when sleeping or confused, resulting in the accidental removal of the gastrointestinal catheter and unplanned extubation. This not only increases the risk of patients, but also brings unnecessary trouble to medical work.

[0004] Secondly, long-term fixation with adhesive tape will irritate the local skin, causing discomfort reactions such as redness, itching, and allergies, and may even cause complications such as local skin ulceration. This not only increases the patient's pain, but also increases the difficulty of nursing. At the same time, the adhesive tape needs to be replaced repeatedly, which increases the workload of nursing. Moreover, the viscosity of the adhesive tape is limited. During daily activities, especially when patients are undergoing enteral nutrition or gastrointestinal decompression, the tube may easily fall off accidentally due to the gravity of the tube or a small pull.

[0005] In addition, adhesive tape fixation also affects the patient's facial cleanliness. When cleaning their faces, patients and their families are often worried about getting the tape wet or tearing it off, which results in the inability to thoroughly clean the sweat stains, dandruff and secretions on the face. This not only increases the risk of infection, but also affects the patient's image and comfort, which is not in line with the humane care concept of modern medicine. Summary of the invention

[0006] The purpose of the utility model is to provide an ear-hook dual-purpose secondary fixation device for nasal gastrointestinal tubes, so as to solve the problem that the secondary fixation method commonly used in clinical practice proposed in the above background technology is to fix the tube to the patient's face by a 3M adhesive tape high-lift platform method.

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] The utility model provides an ear-hook type dual-purpose secondary fixing device for nasal gastrointestinal tubes, such as Figure 1-Figure 4 As shown, the ear hook 1 includes an ear hook 1, which is worn on the patient's ear, an elastic rope 2 is installed between the two ends of the ear hook 1, two pulling ropes 3 are connected to the lower end of the ear hook 1, and a pipe fixing member 5 is installed at the bottom end of the pulling rope 3. An adjustment device 4 is installed on the outer side of the lower end of the ear hook 1, and the adjustment device 4 is used to adjust the length of the pulling rope 3. The device uses the ear hook 1 to be worn on the patient's ear, ensuring the stability of the entire fixing device. The elastic rope 2 installed between the two ends of the ear hook 1 not only enhances the stability of the device, but also enables the device to adapt to the head circumference of different patients, thereby improving the wearing comfort.

[0029] More importantly, the two pulling ropes 3 connected to the lower end of the ear hook 1 and the pipe fixing piece 5 at the bottom provide a precise fixing point for the gastrointestinal pipe. This design avoids the problem of unstable fixation caused by sweat, skin oil, etc. in the traditional adhesive tape fixing method, and effectively reduces the risk of unplanned extubation. At the same time, the pipe fixing piece 5 can firmly clamp the pipe to prevent it from shifting or falling off during the patient's daily activities.

[0030] In addition, the adjustment device 4 installed on the outer side of the lower end of the ear hook 1 allows the length of the pulling rope 3 to be flexibly adjusted according to the actual needs of the patient. This design not only improves the applicability of the device, but also allows the patient to maintain a more comfortable posture during wearing, reducing the discomfort caused by long-term fixation.

[0031] In this embodiment, the adjustment device 4 includes a fixed block 41, the outer wall of the fixed block 41 is connected to the ear hook 1, a rotating member 42 is provided in the middle of the fixed block 41, the bottom end of the rotating member 42 is rotatably connected to the fixed block 41 through a bearing 422, a rope hanging ring 421 is installed on the outer wall of the rotating member 42, and one end of the traction rope 3 is connected to the rope hanging ring 421. The adjustment device 4 in this embodiment realizes the adjustability of the length of the traction rope 3 through the stable connection between the fixed block 41 and the ear hook 1, and the flexible rotation of the rotating member 42 in the fixed block 41. The connection design between the rope hanging ring 421 on the outer wall of the rotating member 42 and one end of the traction rope 3 allows the user to easily adjust the tightness of the traction rope 3 by rotating the rotating member 42, thereby meeting the fixation requirements of different patients and improving the applicability and comfort of the device.

[0032] Specifically, a push rod 44 is installed on one side of the fixed block 41, and one end of the push rod 44 abuts against the outer wall of the rotating member 42. An inner cavity 411 is provided near the push rod 44 on one side of the fixed block 41. Lug plates 441 are installed on both sides of the outer walls of the push rod 44. A return spring 442 is installed between the outer wall of the lug plate 441 and the inner wall of the inner cavity 411. The return spring 442 acts on the lug plate 441 to drive the end of the push rod 44 to press against the outer wall of the rotating member 42. The design of the push rod 44 and its return spring 442 installed on one side of the fixed block 41 provides a stable resistance for the rotating member 42, ensuring that the rotating member 42 can remain in the desired position after adjustment and will not be easily rotated due to a slight touch of external force. This design enhances the stability of the device, prevents accidental changes in the length of the pulling rope 3, and ensures the reliability of pipeline fixation.

[0033] Furthermore, a top block 443 is installed at the end of the top rod 44, a plurality of tooth rings 43 are installed at equal intervals in a ring shape in the middle of the rotating member 42, a plurality of tooth blocks 431 are installed on the outer wall of the tooth ring 43, and the top block 443 at the end of the top rod 44 is stuck between adjacent tooth blocks 431. The top block 443 at the end of the top rod 44 cooperates with the tooth rings 43 and tooth blocks 431 installed at equal intervals in a ring shape on the rotating member 42, thereby realizing the fine adjustment and locking functions of the adjustment device 4. When the user rotates the rotating member 42, the top block 443 will move between the tooth blocks 431 and make a clear "click" sound, prompting the user that a new adjustment position has been reached. This design not only improves the accuracy of the adjustment, but also enables the user to intuitively feel the process and results of the adjustment.

[0034] Furthermore, the pipeline fixing member 5 is a tubular structure, which is used to fix the gastrointestinal decompression tube and the sac jejunal catheter respectively. The tubular structure design of the pipeline fixing member 5 enables it to fix the gastrointestinal decompression tube and the sac jejunal catheter respectively, realizing the dual-use of the device. This design simplifies the pipeline management during the medical process, reduces the burden on patients, and improves the nursing efficiency.

[0035] Furthermore, an anti-skid pad 51 is installed on the inner wall of the pipe fixing member 5. The anti-skid pad 51 installed on the inner wall of the pipe fixing member 5 effectively prevents the pipe from sliding and falling off during the fixing process. This design enhances the stability of the pipe fixing and ensures the safety and stability of the pipe during the patient's daily activities.

[0036] Furthermore, the ear hook 1 is made of lightweight PVC material, which reduces the weight of the entire device and improves the wearing comfort of the patient. At the same time, the PVC material has good durability and corrosion resistance, which prolongs the service life of the device.

[0037] Furthermore, one end of the pipe fixing member 5 is provided with an external thread end, and the other end is provided with an internal thread end, and the two pipe fixing members 5 are connected to each other by bolts. This design facilitates the serial and parallel use of pipes and improves the flexibility and applicability of the device.

[0038] Furthermore, the elastic cord 2 and the pulling cord 3 are made of elastic rubber material, so that the device can better adapt to the patient's head shape and movement during wearing, improving the comfort and stability of the device. At the same time, the rubber material has good wear resistance and anti-aging properties, ensuring the long-term use effect of the device.

[0039] Furthermore, a handle is installed at the outer end of the top rod 44. The user can easily push or pull the top rod 44 by holding the handle, thereby achieving fine adjustment of the rotating member 42. This design improves the operability of the device, allowing patients or medical staff to use the device more conveniently.

[0040] When the ear-hook dual-purpose secondary fixing device for nasal gastrointestinal tubes of the utility model is used, the ear-hook 1 is first worn on the patient's ear, and the ear is used as a support point to ensure the stability of the entire device. The elastic rope 2 between the two ends of the ear-hook 1 automatically adjusts the length according to the patient's head circumference, provides appropriate tightening force, and ensures wearing comfort.

[0041] The bottom end of the pulling rope 3 is connected with a pipe fixing member 5, which is a tubular structure and is designed to fix the gastrointestinal decompression tube and the liquid sac jejunal catheter respectively. The pipe to be fixed is inserted into the pipe fixing member 5, and the anti-skid pad 51 ensures that the pipe will not slide or fall off, providing a stable fixing effect.

[0042] According to the actual needs of the patient, the length of the traction rope 3 is adjusted by the adjustment device 4. The rotating member 42 is rotated to cause the rope hanging ring 421 on its outer wall to drive the traction rope 3 to move, thereby adjusting the tightness of the traction rope 3. During the adjustment process, the end top block 443 of the top rod 44 will move between the tooth blocks 431 of the tooth ring 43 and make a "click" sound, prompting the user that a new adjustment position has been reached. When the desired length is reached, the return spring 442 applies a stable resistance to the top rod 44 through the convex plate 441, ensuring that the rotating member 42 remains in the desired position and will not easily rotate due to a slight touch of external force, thereby realizing the locking function.

[0043] One end of the pipe fixing member 5 is provided with an external thread end, and the other end is provided with an internal thread end, and the two pipe fixing members 5 can be connected to each other by bolts. This design allows the pipes to be used in series and in parallel, which is convenient for pipe management during medical treatment, reduces the burden on patients, and improves nursing efficiency.

[0044] The ear hook 1 is made of lightweight PVC material, which reduces the weight of the entire device and improves the wearing comfort of the patient. The elastic rope 2 and the pull rope 3 are made of elastic rubber material, so that the device can better adapt to the patient's head shape and movement, while ensuring the durability and anti-aging performance of the device.

[0045] A handle is installed at the outer end of the push rod 44, and the user can easily push or pull the push rod 44 by holding the handle to unlock and lock the rotating member 42, thereby achieving fine adjustment of the rotating member 42. This design improves the operability of the device, allowing patients or medical staff to use the device more conveniently and accurately to fix and adjust the pipeline.
