[0002] Nasogastric feeding is a medical procedure that delivers nutrients directly to the stomach through the nose, typically used for patients unable to feed themselves orally. The feeding tube is inserted into the patient's stomach through the nasal cavity or other openings. The food is pre-mixed into a liquid form and injected into the tube using a syringe. The liquid is then fed through the tube, which passes through the patient's nose into the stomach. Examples of feeding methods include administering liquid food, water, and medications. Nasogastric feeding is commonly used for critically ill patients, comatose patients, or patients with swallowing difficulties. With an aging population, many elderly people with health problems or those recovering at home without caregivers also frequently require nasogastric feeding.

[0003] In current technology, most patients using nasogastric tubes are hospitalized patients or bedridden elderly people at home. During the nasogastric feeding stage, due to the busy schedules of medical staff and the lack of professionalism of family caregivers, most bedridden patients or elderly people are left unattended or do not receive careful care. When medical staff assist the elderly with nasogastric feeding, if there are limited staff at the nursing station or family caregivers, it often leads to conflicts in the feeding times of many patients. At this time, it is impossible to monitor the nasogastric feeding process well, which often results in the nasogastric tube falling out without anyone noticing.

[0004] Therefore, a nasogastric tube fixation device is proposed to address the above-mentioned problem, which is to solve the problem that the nasogastric tube is prone to falling off when patients or bedridden elderly people are fed nasally without care. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Specific implementation examples are given below.

[0028] Please see Figures 1 to 5 As shown, this utility model provides an auxiliary fixing device for nasogastric tubes, including a bracket 1; a fixing plate 2 is fixedly connected to the top of the bracket 1; a bearing plate 24 is slidably fitted on one side of the top of the fixing plate 2; a nasal support 11 is fixedly connected to the bracket 1 near the fixing plate 2; a base support 26 is provided inside one end of the bearing plate 24, and the two sides of the base support 26 pass through the bearing plate 24 via shafts; the base support 26 is used to support the nasogastric tube; a metal plate 25 is provided on the upper surface of the bearing plate 24 corresponding to (separately arranged on both sides of the bearing plate 24, and symmetrical or corresponding in position) one end of the base support 26, and the bottom of the metal plate 25 passes through the bearing plate 24 via a sliding rod; a contact piece 28 is fixedly connected to the bottom of the sliding rod.

[0029] During nasogastric feeding, the feeding tube is located between the contact piece 28 and the base 26; a spring 3 is fixedly connected to the top surface of the contact piece 28, and the top of the spring 3 is fixedly connected to the bottom of the support plate 24; the surface of the base 26 is provided with copper contacts 29 corresponding to (separately arranged on both sides of the support plate 24, and symmetrical or corresponding in position) the contact piece 28.

[0030] Specifically, when in use, the bracket 1 is placed on the bridge of the nose of the patient being fed through a nasal tube. The nose pad 11 is used for positioning, which can stably fix the bracket 1 on the bridge of the nose. The fixing plate 2 can be used to engage with the support plate 24.

[0031] In use, first attach the bracket 1 and the fixing plate 2 to the bridge of the patient's nose, then connect the nasogastric tube to the base 26, and finally attach it to the fixing plate 2 to fix the nasogastric tube. By adjusting, the nasogastric tube is inserted into the patient's stomach through the nasal cavity, and then feeding is performed. One end of the nasogastric tube is inserted into the patient's body, while the other end works with the peristaltic pump to guide the liquid food in the nasogastric tube. Automatic nasogastric feeding can be achieved even when no one is watching.

[0032] To monitor the amount of food fed during automatic nasogastric feeding, a contact piece 28 is installed on the support plate 24, and the contact piece 28 is arranged outside the nasogastric tube. When the amount of food fed decreases, the nasogastric tube changes from a full state to a deflated state. At this time, the contact piece 28 moves downward, which drives the metal plate 25 to move downward via the slide rod, and makes contact with the copper contact 29 on the base 26, so that the circuit is connected. The circuit is equipped with a power supply, which is powered by a button battery and installed in the support plate 24. The circuit is also equipped with a signal generator, which can generate an electrical signal when the power is turned on. This signal can be used in conjunction with the nurse station or the mobile terminal of the accompanying family member, or other signal receivers, to trigger the buzzer of the nurse station or other receivers that are matched with the receiver, thereby prompting the nurse to handle the post-feeding care. This automatic nasogastric feeding method with nasogastric feeding volume warning is suitable for nasogastric feeding of elderly people who are not under care. When hospital staff are busy, this device facilitates the allocation of nurses' work without affecting the normal feeding of elderly patients via nasogastric tube. It also avoids the problems of insufficient staff at the nursing station when no one is available to care for the elderly, which could lead to conflicts in feeding among many patients and the easy dislodgement of the nasogastric tube.

[0033] Furthermore, such as Figure 1 and Figure 2As shown, the bracket 1 is configured as a U-shaped structure; a first connecting plate 12 is fixedly connected to the outer side of one end of the bracket 1; a second connecting plate 21 is fixedly connected to the outer side of one end of the fixing plate 2 corresponding to the first connecting plate 12; the first connecting plate 12 and the second connecting plate 21 are fixedly connected by bolts; the U-shaped bracket 1 can be easily clipped onto the patient's nasal bridge to fix the nasogastric tube to the user's face, and the first connecting plate 12 and the second connecting plate 21 on the fixing plate 2 can be fixed by bolts, so that the bracket 1 and the fixing plate 2 can be detached, which can facilitate processing and reduce costs.

[0034] Furthermore, such as Figure 1 As shown, the other end of the bracket 1 is bent upwards, and the bottom surface of the other end of the bracket 1 is parallel to the first connecting plate 12 and the second connecting plate 21; the upward bending of one end of the bracket 1 can be adapted to patients with high nose bridges, preventing the low-lying bracket 1 from causing discomfort to patients with high nose bridges when combined with the nose pad 11.

[0035] Furthermore, such as Figure 2 As shown, the surface of the fixing plate 2 has a sliding groove 22, and the supporting plate 24 slides in conjunction with the sliding groove 22; the fixing plate 2 has slots 23 on both sides of one end near the second connecting plate 21, and the end of the supporting plate 24 facing the slots 23 engages with the slots 23. The fixing plate 2 and the supporting plate 24 slide in conjunction with the sliding groove 22, wherein the supporting plate 24 can be fitted with the nasogastric tube first, and after assembly, it can be slidably fastened onto the fixing plate 2 as a whole. This step-by-step use of the auxiliary device can optimize the nurse's operation and reduce the difficulty of the work.

[0036] Furthermore, such as Figure 3 and Figure 4 As shown, two spring clips (not shown in the figure) are symmetrically arranged inside the two ends of the support plate 24 facing the slot 23, and the spring clips are engaged with the slot 23. The spring clips are arranged at the ends of the support plate 24 and include a spring and a clip. When the spring clip contacts the side of the slide groove 22, it can retract inward. When it corresponds to the slot 23, the spring squeezes the clip to move outward, so that the clip is engaged in the slot 23, completing the engagement between the support plate 24 and the fixing plate 2. In addition, a return spring 3 is provided between the lower surface of the support plate 24 and the upper surface of the contact piece 28. When the tube is full, the return spring 3 is in a compressed state; when the tube is deflated, the return spring 3 is in a stretched state.

[0037] Furthermore, such as Figure 3 and Figure 5As shown, connecting rods 27 are fixed to both sides of the base 26, and the connecting rods 27 penetrate the support plate 24. Several copper contacts 29 are provided on the inner side of one end of the base 26, and the copper contacts 29 are in contact with the surface of the nasogastric tube. The base 26 is fixed to the support plate 24 via the connecting rods 27. A rubber pad is provided on the inner side of the bottom of the base 26 to increase friction and prevent the nasogastric tube from falling off during nasogastric feeding. The copper contacts 29 on the base 26 are electrically connected to and cooperate with a temperature sensor to monitor the temperature of the liquid food in the nasogastric tube. The temperature is displayed as an electrical signal on a mobile terminal such as a nurse's station or a caregiver's phone. If the temperature is too low or too high, the nurse or caregiver needs to actively check to avoid discomfort or burns to the patient.

[0038] Furthermore, the bracket 1 is placed on the user's face with a fixing strap. To improve the user's comfort, the fixing strap can be widened. The fixing strap is made of soft silicone and has dotted protrusions arranged in an array to increase breathability. The edges of the fixing strap are rounded to make it more suitable for the user to wear and make the user more comfortable.

[0039] Working principle: In the current technology, most bedridden elderly people are unattended and need to be fed through a nasogastric tube. However, the nursing station is understaffed and cannot resolve the time conflicts of feeding a large number of elderly people at the same time. Or, when at home, family members who are accompanying the elderly are not busy to take care of them, making feeding troublesome and unsafe. In use, the device of this application involves attaching the support 1 to the bridge of the patient's nose using the nasal support 11 for positioning, thus securing the support 1 stably. The fixing plate 2 engages with the support plate 24. During use, the support 1 and fixing plate 2 are first attached to the patient's nose, then the nasogastric tube is connected to the base 26 and finally secured to the fixing plate 2. Adjustments are made to insert the nasogastric tube into the patient's stomach through the nasal cavity for feeding. One end of the nasogastric tube is inserted into the patient's body, while the other end engages with a peristaltic pump to guide the liquid food within the tube. This allows for automatic nasogastric feeding even without supervision. To monitor the amount of food fed automatically, a contact piece 28 is provided on the support plate 24, positioned outside the nasogastric tube. As the feeding volume decreases, the feeding tube changes from a full state to a deflated state. At this time, the contact piece 28 moves downward, which in turn moves the metal plate 25 downward via the slide rod, making contact with the copper contact 29 on the support plate 24, thus connecting the circuit. The circuit is equipped with a power supply, powered by a button battery, installed in the support plate 24. The circuit also includes a signal generator, which generates an electrical signal when the power is turned on. This signal works in conjunction with the receiver at the nurse station to trigger an alarm on the buzzer matched to the receiver, thereby calling the nurse to handle the post-feeding care. This automatic nasal feeding method combined with nasal feeding volume monitoring is suitable for nasal feeding of elderly people who are unattended. During busy periods, it facilitates the allocation of nurses' work and does not affect the normal nasal feeding of the elderly. It avoids the problem of insufficient staff at the nurse station when there is no one to care for the elderly, and the inability to resolve feeding conflicts among multiple nasal feeding patients.
