Description

Technical Field

[0001] The present invention relates to the technical field of neonatal care, in particular to a tracheal tube fixing device for neonatal care. Background Art

[0002] Neonatal endotracheal tubes are medical devices designed specifically for newborns, typically used for respiratory support. A newborn's respiratory system is fragile, and endotracheal tubes can help maintain airway patency and provide artificial respiration or airway management. Common use cases include neonatal asphyxia, premature infants, respiratory failure, or those requiring mechanical ventilation.

[0003] The document with the prior art publication number CN115624673A provides a tracheal tube fixing device for neonatal care. When the tracheal tube is inserted into the fixing tube and punctures the airtight membrane, the inflation mask inflates and expands to fit the newborn's face, and the inner balloon expands and deforms until the inner balloon contacts the surface of the tracheal tube, thereby fixing the tracheal tube. At this time, the inner balloon in the fixing tube and the surface of the tracheal tube form a closed space, that is, external air cannot enter the connecting tube, and the inner balloon stops inhaling and expanding, which can avoid the tracheal tube being over-compressed and causing ventilation failure.

[0004] In the prior art, a neck strap device is used to fix the head of a newborn. However, the neck strap may cause friction with the skin during long-term use, which may easily cause skin damage or irritation. Especially when the skin of a newborn is relatively delicate, it may cause abrasions, redness, swelling or allergic reactions.

[0005] In summary, the prior art lacks a technology for fixing endotracheal tubes for neonatal care using external fixation. Summary of the Invention

[0010] Preferably, the retracting mechanism includes a motor, the motor is fixedly connected to the inner wall of the base, a bidirectional screw is fixedly connected to the output end of the motor, the bidirectional screw is rotatably connected to the inner wall of the base, the outer walls of both ends of the bidirectional screw are threadedly connected with sliders, a retracting rod is rotatably connected to the slider, the other end of the retracting rod is rotatably connected to the adjustment seat, and a fan gear is fixedly connected to the end of one of the retracting rods connected to the adjustment seat.

[0011] Preferably, a worm is rotatably connected to the bottom of the adjustment seat, and a transmission wheel is fixedly connected to one end of the worm, and the transmission wheel is meshed with the sector gear for transmission.

[0012] Preferably, a rotating shaft is fixedly connected to one end of the top frame, the rotating shaft and the adjustment seat are rotatably connected, a worm gear is fixedly connected to the bottom end of the rotating shaft, the worm gear and the worm are meshed for transmission, and the top frame is slidingly matched with the inner wall of the storage groove.

[0013] Preferably, the adjustment plate is provided with two connecting rod groups in a symmetrical structure and rotatably connected, and the other end of the connecting rod group is rotatably connected to the top frame. One end of one of the connecting rod groups close to the upper side is rotatably connected to an electric push rod B, and the other end of the electric push rod B is rotatably connected to the inner wall of the top frame.

[0014] Preferably, the inner walls of the upper and lower ends of the buffer plate are provided with sliding grooves, and a sliding rod is provided on the inner side of the buffer plate. Both ends of the sliding rod are slidably matched with the inner walls of the sliding groove. Springs A are fixedly connected on both sides of the upper and lower ends of the sliding rod, and the other end of the spring A is fixedly connected to the inner wall of the sliding groove. A sliding seat is slidably matched on the sliding rod, and springs B are fixedly connected on the upper and lower ends of the sliding seat, and the other end of the spring B is fixedly connected to the sliding rod.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. By providing a base with a mattress pressure plate and using the mattress to fix the mattress pressure plate, when fixing the endotracheal tube for neonatal care, the endotracheal tube fixing mechanism is suspended above the neonatal head, without contacting the neonatal head for fixation. This can avoid the compression problem caused by the neck strap or head fixation, so that the neonatal head and neck will not be subjected to unnecessary pressure, helping to maintain comfort and avoid discomfort. This can not only improve nursing efficiency, but also ensure the safety and comfort of the neonate, and promote the healthy development of the neonate.

[0018] 2. By setting up an automatic retraction mechanism, the top frame can be easily removed from the base and accurately positioned above the newborn's head for use. When not in use, it can be stored in the base. This not only improves the convenience and safety of operation, but also saves space, increases comfort, and facilitates maintenance and cleaning of the equipment, thereby optimizing the newborn care environment, improving care efficiency, and ensuring the durability and hygiene of the equipment.

[0019] 3. By arranging a slidable slide rod and slide seat in the buffer plate, the tracheal tube fixing mechanism can move a certain distance in the up, down, left and right directions, thereby avoiding the risk of compression, deviation or falling off of the tracheal tube due to the newborn's head movement or other external forces, helping to prevent the tracheal tube from being subjected to uneven pressure and reducing the occurrence of airway obstruction or ventilation difficulties.

DETAILED DESCRIPTION

[0029] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0030] like Figures 1-8 The illustrated device is a tracheal tube fixing device for neonatal care, comprising a base 1, on which two head limit plates 2 are slidably provided, a retractable mechanism 3 is rotatably connected within the base 1, an adjustment seat 4 is rotatably connected to the retractable mechanism 3, a top frame 5 is rotatably connected to the adjustment seat 4, an adjustment plate 6 is provided below the top frame 5, a buffer plate 7 is fixedly connected to one end of the adjustment plate 6, and a tracheal tube fixing mechanism 8 is provided on one side of the buffer plate 7.

[0031] like Figure 3As shown, a mattress pressure plate 101 is provided at the bottom of the base 1. A sleeve rod 102 is fixedly attached to each end of one side of the mattress pressure plate 101. The other end of the sleeve rod 102 slides through the inner wall of the base 1. A tension spring 103 is fixedly attached to the top of the sleeve rod 102. The other end of the tension spring 103 is fixedly attached to the inner wall of the base 1. A storage slot 104 is provided on the base 1. The tension spring 103 functions to retract the mattress pressure plate 101 toward the base 1, thereby reducing the overall size of the device. This effectively saves storage space and makes it more convenient to carry. Especially when the mattress needs to be stored and carried, it helps to reduce the space occupied, making it easier to put in a backpack, car, or other storage area.

[0032] By providing a base 1 with a mattress pressing plate 101 and using the mattress to fix the mattress pressing plate 101, when fixing the endotracheal tube for neonatal care, the endotracheal tube fixing mechanism 8 is suspended above the neonatal head, and does not need to be fixed in contact with the neonatal head. This can avoid the compression problem caused by the neck strap or head fixation, so that the neonatal head and neck will not be subjected to unnecessary pressure, which helps to maintain comfort and avoid discomfort. This not only improves the efficiency of care, but also ensures the safety and comfort of the neonate, and contributes to the healthy development of the neonate.

[0033] like Figure 3 As shown, a head retaining plate 2 is fixedly connected to one side of a sliding frame 201. An electric push rod A202 is fixedly connected to one end of the sliding frame 201. The electric push rod A202 is fixedly connected to the inner wall of the base 1. A medical silicone pad is provided on one side of the head retaining plate 2. The head retaining plate 2 can secure the newborn's head in a suitable position, preventing involuntary head movement during intubation that could affect intubation accuracy. During intubation, a stable head is crucial for ensuring the correct insertion of the endotracheal tube, avoiding unsuccessful or incorrect intubation due to head shaking.

[0034] like Figure 4 As shown, the retracting and extending mechanism 3 includes a motor 301, which is fixedly connected to the inner wall of the base 1. A bidirectional screw rod 302 is fixedly connected to the output end of the motor 301. The bidirectional screw rod 302 is rotatably connected to the inner wall of the base 1. Sliders 303 are threadedly connected to the outer walls of both ends of the bidirectional screw rod 302. A retracting and extending rod 304 is rotatably connected to the slider 303. The other end of the retracting and extending rod 304 is rotatably connected to the adjustment seat 4. A sector gear 305 is fixedly connected to the end of one of the retracting and extending rods 304 connected to the adjustment seat 4. The motor 301 drives the connected bidirectional screw rod 302 to rotate, so that the bidirectional screw rod 302 can drive the slider 303 to move. At this time, the slider 303 will lift the adjustment seat 4 through the retracting and extending rod 304.

[0035] like Figure 5As shown, a worm 401 is rotatably connected to the bottom of the adjustment seat 4, and a transmission wheel 402 is fixedly connected to one end of the worm 401. The transmission wheel 402 is meshed with the sector gear 305 for transmission.

[0036] like Figure 5 As shown, one end of the top frame 5 is fixedly connected to a rotating shaft 501, which is rotatably connected to the adjustment seat 4. The bottom end of the rotating shaft 501 is fixedly connected to a worm gear 502, which is meshed with the worm 401 for transmission. The top frame 5 is slidably engaged with the inner wall of the storage groove 104. When the adjustment seat 4 moves upward, the fan-shaped gear 305 on the retracting rod 304 drives the worm 401 connected to the transmission wheel 402 to rotate, so that the worm 401 can drive the rotating shaft 501 connected to the worm gear 502 to rotate, so that the rotating shaft 501 can drive the connected top frame 5 to rotate.

[0037] like Figure 6 As shown, two connecting rod groups 601 are symmetrically rotatably connected on the adjustment plate 6. The other ends of the connecting rod groups 601 are rotatably connected to the upper frame 5. One end of one of the connecting rod groups 601, near the upper side, is rotatably connected to an electric push rod B602. The other end of the electric push rod B602 is rotatably connected to the inner wall of the upper frame 5. The electric push rod B602 drives the connected connecting rod group 601 to rotate, so that the connecting rod group 601 drives the tracheal tube securing mechanism 8 to descend to the desired height.

[0038] like Figure 7 As shown, the inner walls of the upper and lower ends of the buffer plate 7 are provided with sliding grooves 701, and a sliding rod 702 is provided on the inner side of the buffer plate 7. Both ends of the sliding rod 702 are slidably matched with the inner walls of the sliding groove 701. Springs A703 are fixedly connected on both sides of the upper and lower ends of the sliding rod 702, and the other end of the spring A703 is fixedly connected to the inner wall of the sliding groove 701. A sliding seat 704 is slidably matched on the sliding rod 702, and springs B705 are fixedly connected on the upper and lower ends of the sliding seat 704, and the other end of the spring B705 is fixedly connected to the sliding rod 702.

[0039] like Figure 8As shown, the tracheal tube fixing mechanism 8 includes a fixing seat 801, one end of which is fixedly connected with the sliding seat 704, a clamping air bag 802 is fixedly connected and arranged on the inner wall of the middle part of the fixing seat 801, a gas pump 803 is fixedly connected and arranged on the fixing seat 801, the output end of the gas pump 803 is in communication with the input end of the clamping air bag 802, a transparent mouth cover 804 is slidingly fitted below the fixing seat 801, and a rubber ring 805 is fixedly connected and arranged at the opening at the top end of the transparent mouth cover 804. The transparent mouth cover 804 not only can improve the visibility of the intubation process, reduce irritation and discomfort during intubation, but also can effectively reduce the risk of infection, improve the operation precision, and ensure the smooth breathing passage of the newborn. The safety, comfort and efficiency of the nursing process are enhanced, and a better nursing environment is provided for the newborn. The rubber ring 805 usually has a certain softness and elasticity, which can adapt to tracheal tubes of different sizes and provide a certain compatibility. In this way, no matter how large or small the tracheal tube is, the rubber ring 805 can play a good fixing role, ensuring that each intubation can be successfully performed. By inflating the clamping air bag 802, uniform pressure can be distributed on the tracheal wall, thereby reducing the risk of pressure injury, airway inflammation or other complications caused by the tracheal tube. The uniform support provided by the clamping air bag 802 effectively reduces the damage caused by local pressure concentration or poor contact of the tube.

[0040] Working principle: when it is necessary to insert a tracheal tube into the mouth of a newborn for nursing, first, the mattress pressing plate 101 is pulled down, so that the mattress is placed between the mattress pressing plate 101 and the base 1, at this time the device can be fixed when it is located at the head of the bed, then the head limiting plate 2 connected with the sliding frame 201 is moved by the electric push rod A 202, so as to limit the head of the newborn;

[0041] Then, after the tracheal tube is inserted into the oral cavity, the bidirectional screw rod 302 connected with the motor 301 is rotated, so that the bidirectional screw rod 302 can drive the sliding block 303 to move, at this time the sliding block 303 will lift the adjusting seat 4 through the retractable rod 304;

[0042] At the same time, when the adjusting seat 4 moves up, the sector gear 305 on the retractable rod 304 drives the transmission wheel 402 connected with the worm 401 to rotate, so that the worm 401 can drive the worm gear 502 connected with the rotating shaft 501 to rotate, so that the rotating shaft 501 can drive the top frame 5 connected with it to rotate above the head of the newborn;

[0043] Then, the connecting rod set 601 connected with the electric push rod B 602 is rotated, so that the connecting rod set 601 drives the tracheal tube fixing mechanism 8 to descend to the appropriate height, then one end of the tracheal tube passes through the rubber ring 805 on the transparent mouth cover 804, and then passes out from the fixing seat 801, then the fixing seat 801 is continuously driven to move downward, so that the transparent mouth cover 804 can be attached to the mouth of the newborn;

[0044] Then, an appropriate amount of air is injected into the clamping balloon 802 by using the air pump 803 so that the clamping balloon 802 can be inflated to clamp and fix the tracheal tube.
