Abstract
Description
Technical Field
[0001] The invention belongs to the field of gastrointestinal medical devices, and in particular relates to a multifunctional nasogastric feeding tube system. Background Art
[0002] Nasogastric feeding is an important medical method that establishes a direct channel to the stomach by gently inserting a special catheter into the stomach through the nasal cavity for infusing food, water and medicine, thereby ensuring that patients who are unable to eat independently or have difficulty swallowing can obtain the necessary nutritional support and drug treatment. This method greatly improves the nutritional status of patients and promotes the recovery process. It also solves the problem of drug intake caused by oral or throat problems and ensures that the drugs can be directly and effectively absorbed and utilized by the body.
[0003] However, in traditional nasogastric feeding practice, a single channel is often used to deliver food and medicine at the same time. Although this practice simplifies the operation process, it brings problems that cannot be ignored. The mixing of drugs and food in the pipeline may lead to mutual contamination, affect the purity and effectiveness of the drugs, and may even cause adverse reactions. Patients with different conditions have different needs for drugs. A single channel is difficult to achieve precise drug delivery for individual conditions and it is difficult to meet the needs of personalized treatment. Especially for situations where direct drug delivery to the lesion is required, traditional methods often cannot guarantee the effective concentration and duration of action of the drug. In order to achieve the expected therapeutic effect, the dosage has to be increased, which not only increases the economic burden on patients, but is also likely to increase the physical burden on patients and cause more complications.
[0004] The patent with publication number CN104323921A proposes a multifunctional nasogastric feeding tube and nasogastric feeding system. The patent has made a number of optimization designs on the basis of ensuring the basic nutritional needs of patients. However, the patent has not made any fundamental changes in the separation of drug and food delivery, and the same pipeline is still used. And the airbag design in the patent is only used to prevent the reflux of gastric contents and avoid aspiration into the lungs. As for how to achieve more refined drug management and how to further reduce the mutual influence between drugs and food, the patent does not provide an effective solution. Summary of the invention

[0018] 2. The connection between the feeding section and the drug administration section is sleeved with an airbag a, and the connection between the drug administration section and the gastroesophageal section is sleeved with an airbag b, and the sleeve a is sleeved on the drug administration section. The combined action of the airbag a and the airbag b can form a sealed space at the local lesion, and the drug administration component administers the drug in the sealed space through the sleeve a, so that less drugs can be used to meet the drug administration needs at the local lesion, reduce drug abuse, and make the treatment more accurate and the efficacy better.
[0019] 3. The connection between the pharyngeal segment and the nasal segment is connected with an air bag C. When in use, the air bag C is placed at the posterior nasal aperture, which can effectively prevent the nasogastric tube from unplanned dislocation or deep penetration into the human body, affecting the nasogastric feeding effect or causing damage to the patient's body.
[0020] 4. The cannula c is sleeved on the pharyngeal segment, and there is an annulus between the pharyngeal segment and the cannula c. The cannula c is provided with capillaries. The airbag control component controls the inflation and exhaust of the airbag c. The drug delivery component is connected to the cannula c through a catheter. The drug delivery component sprays the drug or lubricant in the form of aerosol or microfluid through the capillaries on the cannula c, so that the drug or lubricant is evenly distributed on the outside of the nasogastric tube, which is used to treat friction pain in the nasopharynx, oropharynx, laryngopharynx and esophagus with extremely high clinical incidence, and at the same time avoids drug adverse reactions or choking reactions caused by excessive local drug dosage or liquid volume.
[0021] 5. The external segment also includes an elastic component and memory foam. The elastic component includes a spring. One end of the spring is connected to the fixing piece, and the other end of the spring passes through the outer shell and is connected to the memory foam. Through the combined effect of the memory foam and the spring, the nasogastric tube can be displaced to a certain extent when the human body performs daily activities such as yawning, coughing, sneezing, and head rotation, while ensuring that the nasogastric tube does not completely enter the human body. This allows the patient to have a higher degree of comfort when wearing the nasogastric tube and avoids damage to the human body.
[0022] 6. The external section also includes a fixing component, which includes an ear hook component, a nasal mask, and a connecting component. A nasal mask is provided on the side of the memory foam close to the nasal section. The external section of the nasogastric tube passes through the nasal mask. The airbag control component and the drug delivery component are provided on the connecting component, and the ear hook component is connected to the nasal mask through the connecting component. In general, the nasogastric tube is attached to the patient's face by medical staff using tape or the like. Since the replacement cycle of the nasogastric tube is long and the patient's face and nose secrete a large amount of oil, the tape will gradually lose its stickiness and slip off. Fixing the nasogastric tube to the human face with the ear hook component can maintain the stability of the nasogastric tube and effectively avoid the problem of the nasogastric tube falling off due to fixing with tape.
[0023] 7. The nasogastric tube, balloon a, balloon b, and balloon c are made of transparent materials. The nasogastric tube is marked with scales and includes a guide wire assembly. The guide wire assembly includes a guide wire, an LED light, a camera, and a data interface. The front end of the guide wire is provided with an LED light and a camera, and the rear end of the guide wire is provided with a data interface. Since the key parts of the nasogastric tube are made of transparent materials, the position of each part of the nasogastric tube can be adjusted through the camera and the medical data can be recorded and stored; the data interface can be connected to a variety of display devices such as mobile phones and computers, making the nasogastric tube insertion operation visual.

[0032] Example 1
[0033] like Figure 1As shown, the nasogastric tube is divided into a feeding section 1, a drug delivery section 2, a gastroesophageal section 29, a pharyngeal section 3, a nasal section 30, and an external section 4, which are connected in sequence. The end of the feeding section 1 is hemispherical, and the feeding section 1 is provided with a plurality of circular holes 12 in different directions, which are used to fully ensure the smooth passage of food and avoid blockage of the nasogastric tube. An air bag a5 is sleeved at the connection between the feeding section 1 and the drug delivery section 2, and an air bag b6 is sleeved at the connection between the drug delivery section 2 and the gastroesophageal section 29. The sleeve a15 is sleeved on the drug delivery section 2, and the sleeve b16 is sleeved on the gastroesophageal section 29. The drug delivery component 8 is connected to the sleeve a15, the sleeve b16, and the sleeve c17 through a catheter. The feeding section 1 is provided with a circular hole 12, the sleeve a15 is provided with a fine hole a13, and the sleeve b16 is provided with a fine hole b31. The fine hole a13 and the fine hole b31 are used to evenly apply the drug on the surface of the esophageal and gastric wall mucosa. The pharyngeal segment 3 is about 7-9cm, and the connection between the pharyngeal segment 3 and the nasal segment 30 is sleeved with an airbag c7. The preset pressure value of the airbag c7 in the inflated state is 25cmH2O, and the diameter is about 9mm. The sleeve c17 is sleeved on the pharyngeal segment 3, and the sleeve c17 is provided with fine capillary pores 14. The capillary pores 14 can make the drug or lubricant appear in aerosol or microfluid form when it is given, so that it is evenly distributed on the outer wall of the body cavity and the pipeline, so that the friction pain in the nasopharynx, oropharynx, laryngopharynx and esophagus with extremely high clinical incidence can be treated, and at the same time, it can effectively avoid adverse drug effects or choking reactions caused by excessive local drugs or lubricants. There are several circular holes 12, pores a13, pores b31, and capillary pores 14. There is an annulus between the drug delivery segment 2 and the sleeve a15, an annulus between the gastroesophageal segment 29 and the sleeve b16, and an annulus between the pharyngeal segment 3 and the sleeve c17.
[0034] Airbag a5 is provided with pressure sensor a, inflation component a, and exhaust component a; airbag b6 is provided with pressure sensor b, inflation component b, and exhaust component b; and airbag c7 is provided with pressure sensor c, inflation component c, and exhaust component c. Airbag control component 9 connects and controls pressure sensor a, inflation component a, exhaust component a, pressure sensor b, inflation component b, exhaust component b, pressure sensor c, inflation component c, and exhaust component c. Airbag control component 9 learns the states of airbag a5, airbag b6, and airbag c7 through pressure sensor a, pressure sensor b, and pressure sensor c. After receiving the signals from pressure sensor a, pressure sensor b, and pressure sensor c, airbag control component 9 controls the inflation of airbag a5, airbag b6, and airbag c7 through inflation component a, inflation component b, and inflation component c, and controls the exhaust of airbag a5, airbag b6, and airbag c7 through exhaust component a, exhaust component b, and exhaust component c, respectively. The airbag a5 and the airbag b6 are inflated by the airbag control component 9, and the airbag a5 and the airbag b6 expand and fit the human esophagus, so that a closed space is formed between the outer wall of the sleeve a15 and part of the human esophagus. At this time, the drug is delivered to the space between the sleeve a15 and the drug delivery section 2 by the drug delivery component 8, and the drug moves from the fine hole a13 on the sleeve a15 to the closed space, thereby achieving the purpose of long-term drug infusion treatment in the local part of the human esophagus. By adjusting the position of the nasogastric tube in the human body, the airbag c7 is located at the posterior nasal aperture of the human body. When the nasogastric tube is adjusted, the airbag c7 is inflated by the airbag control component 9 to prevent the nasogastric tube from accidentally penetrating or coming out of the human body.
[0035] One end of the external segment 4 is connected to the gastroesophageal segment 29, and the other end of the external segment 4 is an opening, and the shape of the opening matches the food supply device. The external segment 4 is provided with an elastic component 10, a memory foam 11 and a fixed component, and the memory foam 11 is located between the elastic component 10 and the fixed component.
[0036] like Figure 2As shown, the elastic component 10 includes a shell 101, a fixing rod 102, a fixing piece 103, a spring 104, a sealing ring a105, a sealing ring b106, a sealing ring c107, and a sealing ring d108. The shell 101 is sleeved on the external section 4 of the nasogastric tube, the fixing piece 103 is fixedly arranged on the inner side of the shell 101, the fixing rod 102 passes through the shell 101 and is fixedly connected to the fixing piece 103, one end of the spring 104 is connected to the fixing piece 103, and the other end of the spring 104 is connected to the memory foam 11, the sealing ring a105, the sealing ring b106, the sealing ring c107, and the sealing ring d108 are all semi-annular, and the sealing ring a105, the sealing ring b106, the sealing ring c107, and the sealing ring d108 are arranged on the inner side of the shell 101. The fixing rod 102 can conveniently adjust the depth of the nasogastric tube entering the human body, and the spring 104 can make the depth of the nasogastric tube entering the human body slightly change during the patient's daily activities, thereby avoiding the damage to the posterior nasal mucosa caused by only maintaining the depth of the nasogastric tube entering the human body through the air bag c7. The sealing ring a105, the sealing ring b106, the sealing ring c107, and the sealing ring d108 are soft silicone biomaterials, which are used to increase the friction between the shell 101 and the wall of the nasogastric tube.
[0037] like Figure 3 As shown, the fixing assembly includes a nasal mask 18, a V-shaped belt a19, a V-shaped belt b20, a horizontal belt a21, a horizontal belt b22, an ear hook a23, and an ear hook b24. The end points of the V-shaped belt a19 are respectively connected to the nasal mask 18 and the ear hook a23, the end points of the V-shaped belt b20 are respectively connected to the nasal mask 18 and the ear hook b24, one end of the horizontal belt a21 is connected to the nasal mask 18, and the other end of the horizontal belt a21 is connected to the V-shaped belt a19, one end of the horizontal belt b22 is connected to the nasal mask 18, and the other end of the horizontal belt b22 is connected to the V-shaped belt b20, the nasal mask 18 is arranged on the side of the memory foam 11 close to the nasal cavity section 30, the external section 4 of the nasogastric tube passes through the nasal mask 18, the airbag control component 9 is arranged on the horizontal belt b22, and the drug delivery component 8 is arranged on the V-shaped belt b20. The nose mask 18, V-belt a19, V-belt b20, horizontal belt a21, and horizontal belt b22 are all made of breathable and sweat-absorbing elastic materials, such as four-sided stretch fabric, which can be easily breathable and absorb facial sweat, thereby improving comfort. In addition, the V-belt a19, V-belt b20, horizontal belt a21, and horizontal belt b22 are all flat belts that can fit the skin, effectively reduce the feeling of being tightened, and greatly improve the comfort of the patient.
[0038] like Figure 4As shown, the multifunctional nasogastric tube system also includes a guide wire assembly, which includes a guide wire 25, an LED light 26, a camera 27, and a data interface 28. The front end of the guide wire 25 is provided with an LED light 26 and a camera 27, and the rear end of the guide wire 25 is provided with a data interface 28. The LED light 26 and the camera 27 are used in combination, and the LED light 26 can illuminate the inside of the nasogastric tube and the esophagus. The camera 27 takes photos and videos of the inside of the nasogastric tube and the esophagus. The data interface 28 can be a Type-C interface, which can be connected to a variety of display devices such as mobile phones. Therefore, the guide wire assembly can have functions such as taking photos, recording, and storing data. Since the nasogastric tube pipeline, airbag a5, airbag b6, and airbag c7 are made of transparent materials, the insertion operation of the nasogastric tube can be visualized through the guide wire assembly, and the fixed positions of each balloon can be clearly seen, and it can also facilitate later position monitoring and adjustment.
