Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, and more specifically to a nasogastric feeding alarm device to prevent reflux. Background Technology

[0002] Visual nasogastric feeding catheters are typically based on ordinary nasogastric tubes, but integrate a miniature camera device and a matching data transmission system. The front end is usually equipped with a miniature camera that can capture real-time image information of the catheter's location, allowing medical staff to intuitively see the specific location of the catheter in the nasal cavity, esophagus, and even the stomach, as well as the condition of the surrounding tissues.

[0003] When inserting a traditional nasogastric tube, the angle between the nasal cavity and the esophagus can cause the tube tip to easily come into contact with the corresponding tissues. When the tip is pressed against the mucosa of the nasal cavity or esophagus, the continuous pressure can easily tear or abrade the mucosa, damaging its integrity and causing local bleeding. If the tip remains pressed against the tissue, it will be difficult to pass through the crucial junction between the nasal cavity and the esophagus, ultimately leading to insertion failure. This necessitates a restart, causing more pain for the patient, adding extra workload for medical staff, and potentially delaying the optimal time for the patient to receive timely nutritional support through nasogastric feeding. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a nasogastric feeding alarm device to prevent backflow, so as to solve the problems existing in the background art.

[0005] This utility model provides the following technical solution: a nasogastric feeding alarm device to prevent backflow, comprising a sleeve, an injection head fixedly connected to the end face of the sleeve, an injection groove formed inside the injection head, a groove formed on the inner wall of the injection groove, a connecting strap fixedly connected to the surface of the injection head, a silicone plug fixedly connected to the surface of the connecting strap, protrusions fixedly connected at equal intervals to the surface of the silicone plug, an active airbag fixedly connected at equal intervals to the surface of the injection head, and a connecting tube connected to the active airbag fixedly connected inside the injection head. The sleeve has an inner tube fixedly connected inside, and a corrugated tube fixedly connected to the end of the inner tube away from the feeding head. A liquid outlet tube is fixedly connected to the end face of the corrugated tube away from the inner tube. A rear guide block is fixedly connected to the outer surface of the sleeve. An elastic ring is fixedly connected to the side of the rear guide block. A front guide block is fixedly connected to the surface of the elastic ring away from the rear guide block. Driven airbags are installed at equal intervals inside the elastic ring. Movable grooves are opened inside the rear guide block and the front guide block. A camera component is fixedly installed inside the front guide block.

[0006] Furthermore, the surface of the elastic ring is provided with through holes at equal intervals, the outer surface of the driven airbag is inserted into the inside of the through holes, and the end of the connecting tube away from the active airbag is fixedly connected to the surface of the driven airbag.

[0007] Furthermore, the interior of the active airbag is connected to the interior of the driven airbag via a connecting tube, and the elastic ring is a silicone ring.

[0008] Furthermore, the surface of the driven airbag near the connecting pipe is fixedly connected to the surface of the rear guide block, and the surface of the driven airbag away from the connecting pipe abuts against the surface of the front guide block.

[0009] Furthermore, the size of the silicone plug matches the feeding trough, the protrusion is hemispherical, the inner wall of the groove is arc-shaped, the silicone plug is a silicone block, and a pressure alarm is fixedly installed on the surface of the silicone plug. When the silicone plug is sealed and inserted into the feeding trough, the sensor at the input end of the pressure alarm is located inside the feeding trough.

[0010] Furthermore, the end of the inner tube away from the corrugated pipe is connected to the interior of the feeding tank, the outer surface of the connecting pipe is fixedly connected to the interior of the sleeve, and the output end of the camera assembly extends to the outside of the front guide block.

[0011] Furthermore, a guide wire is fixedly connected inside the sleeve, and a side tube communicating with the inside is fixedly connected to the outer surface of the sleeve. A duckbill valve is fixedly installed inside the side tube.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. This utility model, through active airbag control of driven airbag expansion, allows for flexible rotation of the front guide block as needed. This enables more precise control of the rotation direction and angle of the discharge tube, facilitating accurate placement of the nasogastric tube by medical staff, improving operational accuracy and success rate, and reducing adverse effects caused by positional deviations. By incorporating a corrugated tube, it prevents tube bending during rotation, ensuring a continuous and stable delivery of nutrients or therapeutic drugs to the patient, thus improving the safety and reliability of nasogastric tube use.

[0014] 2. This utility model, by setting protrusions and grooves, enhances the stability of the silicone plug sealing the inside of the feeding tank after the protrusions are engaged inside the grooves, improving the sealing performance of the feeding tank, preventing infection, and enhancing safety. By installing a pressure alarm inside the silicone plug, when backflow occurs, the internal pressure of the inner tube increases and is detected by the pressure alarm, allowing medical staff or caregivers to react quickly, such as pausing nasogastric feeding or adjusting the patient's position, thereby effectively preventing reflux from entering the respiratory tract, significantly reducing the incidence of aspiration pneumonia, and protecting the patient's respiratory health and life safety. By setting a guidewire, the strength of the cannula can be strengthened. By setting a side tube and a duckbill valve, positive pressure feeding can be achieved without interrupting the main lumen for continuous enteral feeding. Attached Figure Description

[0021] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0022] Figures 1-5 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-5 The present invention will be further described below.

[0023] Specifically, a nasogastric feeding alarm device for preventing backflow includes a sleeve 1, with a feeding head 3 fixedly connected to the end face of the sleeve 1. The feeding head 3 has a feeding groove 2 inside, and a groove 7 is formed on the inner wall of the feeding groove 2. A connecting strap 4 is fixedly connected to the surface of the feeding head 3, and a silicone plug 5 is fixedly connected to the surface of the connecting strap 4. Protrusions 6 are fixedly connected at equal intervals to the surface of the silicone plug 5. Active airbags 8 are fixedly connected at equal intervals to the surface of the feeding head 3. A connecting tube 9 communicating with the active airbag 8 is fixedly connected inside the feeding head 3. An inner tube 1 is fixedly connected inside the sleeve 1. 0. A corrugated pipe 11 is fixedly connected to the end of the inner tube 10 away from the feeding head 3. A liquid outlet pipe 12 is fixedly connected to the end face of the corrugated pipe 11 away from the inner tube 10. A rear guide block 13 is fixedly connected to the outer surface of the sleeve 1. An elastic ring 14 is fixedly connected to the side of the rear guide block 13. A front guide block 17 is fixedly connected to the surface of the elastic ring 14 away from the rear guide block 13. Driven airbags 15 are installed equidistantly inside the elastic ring 14. Movable grooves 16 are opened inside the rear guide block 13 and the front guide block 17. A camera component 18 is fixedly installed inside the front guide block 17.

[0024] In this implementation scheme, the expansion of the driven airbag 15 is controlled by the active airbag 8, and the front guide block 17 can be rotated flexibly as needed. This allows for more precise control of the rotation direction and angle of the discharge tube 12, making it easier for medical staff to accurately place the nasogastric tube in the appropriate position, improving the accuracy and success rate of the operation, and reducing the adverse effects caused by positional deviations. By setting the corrugated tube 11, the tube can bend when the discharge tube 12 rotates, ensuring that nutrients or therapeutic drugs can be continuously and stably delivered to the patient, thus improving the safety and reliability of nasogastric tube use.

[0025] Specifically, the surface of the elastic ring 14 is provided with through holes 141 at equal intervals, the outer surface of the driven airbag 15 is inserted into the inside of the through holes 141, and the end of the connecting tube 9 away from the active airbag 8 is fixedly connected to the surface of the driven airbag 15.

[0026] In this embodiment, by providing through hole 141, the surface of driven airbag 15 can be made to abut against the surface of front guide block 17, and the front guide block 17 can be deflected.

[0027] Specifically, the interior of the active airbag 8 is connected to the interior of the passive airbag 15 via the connecting tube 9, and the elastic ring 14 is a silicone ring.

[0028] In this embodiment, since the elastic ring 14 is a silicone ring, when the driven airbag 15 expands, the elastic ring 14 can deform and adapt to the deflection of the front guide block 17.

[0029] Specifically, the surface of the driven airbag 15 near the connecting pipe 9 is fixedly connected to the surface of the rear guide block 13, and the surface of the driven airbag 15 away from the connecting pipe 9 abuts against the surface of the front guide block 17.

[0030] In this embodiment, when the surface of the driven airbag 15 abuts against the surface of the front guide block 17, it can slowly drive the front guide block 17 to rotate.

[0031] Specifically, the silicone plug 5 and the feeding trough 2 are matched in size, the protrusion 6 is hemispherical, the inner wall of the groove 7 is arc-shaped, the silicone plug 5 is a silicone block, and a pressure alarm 51 is fixedly installed on the surface of the silicone plug 5. When the silicone plug 5 is sealed and inserted into the feeding trough 2, the sensor at the input end of the pressure alarm 51 is located inside the feeding trough 2.

[0032] In this implementation scheme, by setting up protrusion 6 and groove 7, when protrusion 6 is engaged inside groove 7, the stability of the silicone plug 5 after sealing the inside of the feeding tank 2 can be enhanced, improving the sealing of the inside of the feeding tank 2, avoiding infection, and enhancing safety. By installing pressure alarm 51 inside silicone plug 5, when backflow occurs, the pressure inside the inner tube 10 will increase and be detected by pressure alarm 51, triggering an alarm. This allows medical staff or caregivers to react quickly, such as pausing nasogastric feeding or adjusting the patient's position, thereby effectively preventing reflux from entering the respiratory tract, significantly reducing the incidence of aspiration pneumonia, and protecting the patient's respiratory health and life safety.

[0033] Specifically, the end of the inner tube 10 away from the bellows 11 is connected to the inside of the feeding tank 2, the outer surface of the connecting pipe 9 is fixedly connected to the inside of the sleeve 1, and the output end of the camera component 18 extends to the outside of the front guide block 17.

[0034] In this embodiment, the camera component 18 can be set up to monitor the intubation process, which facilitates intubation.

[0035] Specifically, a guide wire 101 is fixedly connected inside the sleeve 1, and a side tube 102 communicating with the inside is fixedly connected to the outer surface of the sleeve 1. A duckbill valve 103 is fixedly installed inside the side tube 102.

[0036] In this embodiment, by setting the guide wire 101, the strength of the cannula 1 can be strengthened. By setting the side tube 102 and the duckbill valve 103, positive pressure feeding can be achieved without interrupting the main lumen for continuous enteral feeding.

[0037] The working principle and usage process of this utility model are as follows: During use, hold the cannula 1 and insert the front guide block 17 into the nasal cavity and esophagus. The insertion is then observed through the camera component 18. At a turning point, press the corresponding active airbag 8. The active airbag 8 forces air into the driven airbag 15 through the connecting tube 9. Due to the expansion of the driven airbag 15, the position of the front guide block 17 at that angle is rotated. This allows for precise control of the rotation direction and angle of the discharge tube 12, facilitating accurate placement of the nasogastric tube by medical personnel, improving operational accuracy and success rate, and reducing adverse effects caused by positional deviations. The corrugated tube 11 further enhances this effect. To prevent the outlet tube 12 from twisting during rotation, this ensures a continuous and stable delivery of nutrients or medications to the patient, improving the safety and reliability of the nasogastric tube. During rotation, the outlet tube 12 deflects between the corrugated tube 11 and the inner tube 10. Simultaneously, a portion of the elastic ring 14 at the expansion position of the driven airbag 15 deforms, increasing its thickness. After rotating the front guide block 17 and the outlet tube 12 to the appropriate angle, insertion can continue. When no angle adjustment is needed, after stopping the pressure applied to the active airbag 8, the deformed elastic ring 14 quickly returns to its original position, pushing the air inside the driven airbag 15 back into the active airbag 8.

[0038] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
