Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a neonatal nasogastric feeding fixation frame. Background Technology

[0002] Currently, nasogastric tube feeding is a common technique for newborns, mainly for premature infants with poor sucking and swallowing abilities and newborns who cannot eat orally due to various diseases. To ensure sufficient energy supply, a nasogastric tube is often placed for feeding. However, the traditional nasogastric feeding method is now widely used in clinical practice, which has caused many clinical complications, such as gastroesophageal reflux, diarrhea, nausea, vomiting, and even respiratory arrest and suffocation. The commonly used nasogastric feeding method involves nurses manually pushing milk into the infant's stomach through the nasogastric tube using a syringe. This method is time-consuming and the injection speed is uneven, which can easily cause a sudden increase in the infant's stomach contents, leading to gastrointestinal dysfunction and a high incidence of other complications such as abdominal distension and vomiting. Improvements are urgently needed. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a reasonably designed and easy-to-use neonatal nasogastric feeding fixation device. This device not only facilitates the fixation of the gastric tube but also controls the injection speed, preventing a sudden increase in the infant's stomach contents and avoiding gastrointestinal dysfunction, thus reducing the occurrence of other complications such as abdominal distension and vomiting.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: it includes a box body, a connecting pipe, a limiting mechanism, and a gastric tube fixing mechanism. The limiting mechanism is fixed on both the front and rear sides of the outer side wall of one side of the box body. A connecting pipe is inserted into the other side wall of the box body. A gastric tube fixing mechanism is sleeved on the outer end of the connecting pipe. A flow control valve is provided on the connecting pipe. The flow control valve is located inside the box body. A pump is fixed on the inner side wall of one side of the box body. The outlet of the pump is connected to the connecting pipe. An inlet pipe is connected to the inlet of the pump.

[0005] The aforementioned limiting mechanisms are all composed of a limiting rod, a limiting ring, a support frame, a limiting plate, an internally threaded tube, a screw, and a hand-tightening mechanism. The limiting rod is arranged in an inverted "L" shape. The horizontal bar of the limiting rod is fixed to the outer side wall of one side of the housing. The vertical bar of the limiting rod is inserted into the limiting ring. A support frame is fixed to one side of the outer ring wall of the limiting ring. The support frame is arranged in an inverted "U" shape. A limiting plate is provided on one side of the support frame. A screw is fixed to one side wall of the limiting plate. The other end of the screw is inserted into the internally threaded tube and connected by a thread. The other end of the internally threaded tube passes through the bearing in one side wall of the support frame and is fixedly connected to the hand-tightening mechanism. Several positioning holes are fixed at equal angles on the outer side wall of one side of the support frame. After the positioning bolt passes through the hand-tightening mechanism, it is screwed into one of the positioning holes by a thread.

[0006] The aforementioned gastric tube fixation mechanism consists of a breathing mask, a first elastic band, a second elastic band, a first positioning rod, and a second positioning rod. The breathing mask is fitted onto the connecting tube. Several ventilation holes are evenly spaced on the outer ring wall of the breathing mask. A first elastic band is located on the upper side of one side wall of the breathing mask. A first positioning ring is fixed to the other end of the first elastic band. The first positioning ring is fitted with the first positioning rod. The first positioning rod is fixed to the upper side of the other side wall of the breathing mask. A second elastic band is located on the lower side of the first positioning rod. The second elastic band is fixed to the lower side of the front side wall of the breathing mask. A second positioning ring is fixed to the other end of the second elastic band. The second positioning ring is fitted with the second positioning rod. The second positioning rod is fixed to the lower side of one side wall of the breathing mask.

[0007] Furthermore, a first anti-slip pad is fixed on one side wall of the limiting plate.

[0008] Furthermore, a slider is fixed at the center of the upper side wall of the limiting plate. The slider is slidably mounted on a slide rail, which is fixed to the inner side wall of the lower side of the support frame. The upper side of the limiting plate slides on the slide rail via the slider to limit the position of the limiting plate.

[0009] Furthermore, a heating plate is fixed on the inner wall of the lower side of the box. The heating plate is connected to a controller, which is fixed on the inner wall of one side of the box. The controller is also connected to a temperature sensor, which is fixed on a first insert rod. The first insert rod is inserted into a first sleeve and secured with bolts. The first sleeve is fixed on the inner wall of one side of the box. The baby bottle is placed on the heating plate. After loosening the bolts on the first sleeve, the temperature sensor is moved to contact the baby bottle. When the temperature of the milk powder in the baby bottle is low, the temperature sensor transmits a signal to the controller, which then activates the heating plate to heat the baby bottle.

[0010] Furthermore, the upper and lower sides of the box body are equipped with limiting frames, each of which consists of a spring, an arc-shaped clamp, a second sleeve, and a second rod. The springs are fixed to the inner walls of the left and right sides of the box body, and the other end of the springs is fixed to an arc-shaped clamp. The arcs of the two arc-shaped clamps are set opposite to each other. The front and rear sides of the outer wall of the arc-shaped clamp are fixed with second rods. The second rods are set inside the springs on the front and rear sides. The outer side of the second rod is fitted with a second sleeve. The other end of the second sleeve is fixed to the inner wall of the left and right sides of the box body. In use, the baby bottle is placed inside the box body and between the two arc-shaped clamps. The spring pushes the arc-shaped clamps towards the center, thus limiting the baby bottle inside the box body.

[0011] Furthermore, a second anti-slip pad is fixed on the inner wall of the arc-shaped clamp.

[0012] The working principle of this invention is as follows: In use, the support frame in the limiting mechanism is secured to the railing beside the hospital bed. Then, the hand-tightening mechanism is turned, causing the internal threaded tube to rotate. This causes the internal threaded tube to move the screw towards the inside of the support frame until the limiting plate abuts against the railing. The positioning bolt is then inserted into the corresponding positioning hole. Next, the limiting rod on the box is inserted into the limiting ring. The baby bottle is placed inside the box, and the inlet tube is inserted into the connecting tube. Then, the flow control valve is adjusted according to the newborn's condition. Finally, the gastric tube is inserted through… The newborn's nose is inserted into the stomach. The outer end of the gastric tube is connected to the connecting tube. The breathing mask is then slid to one side of the gastric tube to a suitable position. The gastric tube is then secured to the breathing mask with medical tape. Elastic bands No. 1 and No. 2 are then wrapped around the back of the newborn's head. Positioning rings No. 1 and No. 2 are then placed on positioning rods No. 1 and No. 2. Finally, the pump is activated. The pump draws the formula from the bottle into the connecting tube, and then through the connecting tube into the gastric tube to feed the newborn.

[0013] The beneficial effects of the present invention after adopting the above structure are as follows:

[0014] 1. While facilitating the fixation of the gastric tube, the injection rate can be controlled, preventing a sudden increase in the child's gastric contents and avoiding gastrointestinal dysfunction, thus reducing the occurrence of other complications such as abdominal distension and vomiting;

[0015] 2. The gastric tube is fixed to the breathing mask, which is then secured to the newborn's head with elastic bands No. 1 and No. 2. It is directly attached to the newborn's skin without the need for adhesive tape, thus protecting the skin.

[0016] 3. The formula powder inside the bottle is pumped into the connecting tube by a pump, and then transferred into the feeding tube through the connecting tube. No medical staff need to push it manually, saving time and effort. Attached Figure Description

The gastric tube fixing mechanism 4 consists of a breathing mask 4-1, a first elastic band 4-2, a second elastic band 4-3, a first positioning rod 4-4, and a second positioning rod 4-5. The breathing mask 4-1 is fitted onto the connecting tube 3. The outer ring wall of the breathing mask 4-1... Several ventilation holes 4-8 are evenly spaced on the upper part of the breathing mask 4-1. An elastic band 4-2 is glued and fixed to the upper side of the rear wall of the breathing mask 4-1. A positioning ring 4-6 is tied and fixed to the left end of the elastic band 4-2. The positioning ring 4-6 is fitted with a positioning rod 4-4. The positioning rod 4-4 is glued and fixed to the upper side of the front wall of the breathing mask 4-1. A second elastic band 4-3 is located below the positioning rod 4-4. The second elastic band 4-3 is glued and fixed to the lower side of the front wall of the breathing mask 4-1. On the other end of the second elastic band 4-3, a second positioning ring 4-7 is fixedly tied. The second positioning ring 4-7 is fitted with the second positioning rod 4-5.

[0030] The working principle of this specific implementation is as follows: In use, the support frame 2-3 in the limiting mechanism 2 is clipped onto the railing next to the hospital bed. Then, the hand-tightening mechanism 2-7 is turned, which drives the internal threaded tube 2-5 to rotate. The internal threaded tube 2-5 drives the screw 2-6 to move inward toward the support frame 2-3 until the limiting plate 2-4 abuts against the railing. Then, the positioning bolt 2-9 is inserted into the corresponding positioning hole 2-8. Next, the limiting rod 2-1 on the box 1 is inserted into the limiting ring 2-2. The baby bottle is placed inside the box 1, between the two arc-shaped clamps 16-2. The spring 16-1 pushes the arc-shaped clamps 16-2 toward the center, limiting the baby bottle inside the box 1. At this time, the baby bottle is placed on the heating plate 11. After loosening the bolt on the first sleeve 15, the temperature sensor 13 is moved to contact the baby bottle. When the temperature of the milk powder in the baby bottle is low... The temperature sensor 13 transmits a signal to the controller 12, which then activates the heating plate 11 to heat the bottle. The inlet tube 7 is then inserted into the connecting tube 3. The flow control valve 5 is adjusted according to the newborn's condition. The gastric tube is then inserted into the newborn's stomach through the nose, and the outer end of the gastric tube is connected to the connecting tube 3. The breathing mask 4-1 is then slid to the side of the gastric tube to a suitable position, and the gastric tube is fixed to the breathing mask 4-1 with medical tape. The first elastic band 4-2 and the second elastic band 4-3 are then wrapped around the back of the newborn's head, and the first positioning ring 4-6 and the second positioning ring 4-7 are fitted onto the first positioning rod 4-4 and the second positioning rod 4-5. Finally, the pump 6 is activated, which pumps the milk powder from the bottle into the connecting tube 3, and then into the gastric tube to feed the newborn.

[0031] The beneficial effects of this specific embodiment after adopting the above structure are as follows:

[0032] 1. While facilitating the fixation of the gastric tube, the injection rate can be controlled, preventing a sudden increase in the child's gastric contents and avoiding gastrointestinal dysfunction, thus reducing the occurrence of other complications such as abdominal distension and vomiting;

[0033] 2. The gastric tube is fixed to the breathing mask 4-1. The breathing mask 4-1 is fixed to the newborn's head by elastic band 4-2 and elastic band 4-3. It is directly attached to the newborn's skin without the need for fixing tape, which has a protective effect on the skin.

[0034] 3. The formula powder inside the bottle is pumped into the connecting tube 3 by the pump 6, and then transferred into the feeding tube through the connecting tube 3. No medical staff need to push it manually, saving time and effort.

[0035] 4. A heating plate 11 is provided on the lower side inside the box 1, which can heat the baby bottle during use, so that the milk powder is kept at a constant temperature.

[0036] 5. Limiting brackets 16 are provided on both the upper and lower sides inside the box 1. The baby bottle can be fixed by the limiting brackets 16 to prevent the baby bottle from tipping over when it is accidentally hit by the box 1.
