Abstract
Description
Technical Field
[0001] This invention relates to the field of neonatal care technology, and in particular to a tracheal tube fixation device for neonatal care. Background Technology
[0002] A neonatal endotracheal tube is a medical device specifically designed for newborns, typically used for respiratory support. Newborns have fragile respiratory systems, and endotracheal tubes help maintain airway patency, providing artificial respiration or airway management. Common applications include neonatal asphyxia, premature infants, respiratory failure, or situations requiring mechanical ventilation.
[0003] The prior art publication CN115624673A provides a tracheal tube fixing device for neonatal care. When the tracheal tube is inserted into the fixing cylinder and punctures the airtight membrane, the inflatable mask inflates and expands to fit against the newborn's face. The inner bladder expands and deforms until it contacts the surface of the tracheal tube, thus fixing the tracheal tube. At this time, the inner bladder inside the fixing cylinder and the surface of the tracheal tube form a closed space, that is, external gas cannot enter the connecting tube, and the inner bladder stops inhaling and expanding, which can avoid the situation where the tracheal tube cannot be ventilated due to excessive compression.
[0004] In the use of existing technology, the neck strap is used to fix the newborn's head. However, the neck strap binding method may cause friction with the skin during long-term use, which can easily lead to skin damage or irritation. This is especially true for the delicate skin of newborns, which may cause abrasions, redness, or allergic reactions.
[0005] In summary, the existing technology lacks a technique for external fixation of endotracheal tubes used in neonatal care. Summary of the Invention
[0006] The purpose of this invention is to address the shortcomings of the prior art by providing a tracheal tube fixation device for neonatal care.
[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a tracheal tube fixing device for neonatal care, comprising a base, two head limiting plates slidably fitted on the base, a retractable mechanism rotatably connected inside the base, an adjusting seat rotatably connected on the retractable mechanism, a top frame rotatably connected on the adjusting seat, an adjusting plate below the top frame, a buffer plate fixedly connected to one end of the adjusting plate, and a tracheal tube fixing mechanism on one side of the buffer plate.
[0008] Preferably, the base has a mattress pressure plate at the bottom, and a sleeve rod is fixedly connected to both ends of one side of the mattress pressure plate. The other end of the sleeve rod is slidably connected to the inner wall of the base. A tension spring is fixedly connected to the top of the sleeve rod, and the other end of the tension spring is fixedly connected to the inner wall of the base. The base has a storage groove.
[0009] Preferably, a sliding frame is fixedly connected to one side of the head limiting plate, and an electric push rod A is fixedly connected to one end of the sliding frame. The electric push rod A is fixedly connected to the inner wall of the base, and a medical silicone pad is provided on one side of the head limiting plate.
[0010] Preferably, the retracting mechanism includes a motor, which is fixedly connected to the inner wall of the base. A bidirectional lead screw is fixedly connected to the output end of the motor. The bidirectional lead screw is rotatably connected to the inner wall of the base. A slider is threadedly connected to the outer wall of both ends of the bidirectional lead screw. A retracting rod is rotatably connected to the slider. The other end of the retracting rod is rotatably connected to an adjusting seat. A sector gear is fixedly connected to the end of one of the retracting rods connected to the adjusting seat.
[0011] Preferably, a worm gear is rotatably connected to the bottom of the adjusting seat, and a transmission wheel is fixedly connected to one end of the worm gear. The transmission wheel meshes with a sector gear for transmission.
[0012] Preferably, a rotating shaft is fixedly connected to one end of the top frame, the rotating shaft is rotatably connected to the adjusting seat, a worm gear is fixedly connected to the bottom end of the rotating shaft, the worm gear is meshed with a worm for transmission, and the top frame is slidably fitted to the inner wall of the storage groove.
[0013] Preferably, the adjustment plate has two symmetrically connected linkages, with the other end of each linkage rotatably connected to the top frame. One of the linkages is rotatably connected to an electric actuator B at its upper end, and the other end of the electric actuator B is rotatably connected to the inner wall of the top frame.
[0014] Preferably, the inner walls of both 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 engaged with the inner wall of the sliding groove. Springs A are fixedly connected to both sides of the upper and lower ends of the sliding rod, and the other end of spring A is fixedly connected to the inner wall of the sliding groove. A sliding seat is slidably engaged on the sliding rod, and springs B are fixedly connected to both ends of the sliding seat. The other end of spring B is fixedly connected to the sliding rod.
[0015] Preferably, the endotracheal tube fixing mechanism includes a fixing seat, one end of which is fixedly connected to a slide, a clamping airbag is fixedly connected to the inner wall of the middle part of the fixing seat, an air pump is fixedly connected to the fixing seat, the output end of the air pump is connected to the input end of the clamping airbag, a transparent mouthpiece is slidably fitted below the fixing seat, and a rubber ring is fixedly connected to the top opening of the transparent mouthpiece.
[0016] Compared with the prior art, the present invention has the following beneficial effects:
[0017] 1. By setting a base with a mattress pressure plate, the mattress is used to fix the mattress pressure plate, so that when fixing the endotracheal tube for newborn care, the endotracheal tube fixing mechanism is suspended above the newborn's head without contact with the newborn's head. This avoids the pressure problems caused by neck straps or head fixation, so that the newborn's head and neck are not subjected to unnecessary pressure, which helps to maintain comfort and avoid discomfort. This not only improves care efficiency, but also ensures the safety and comfort of the newborn, which is conducive to the healthy development of the newborn.
[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 back into the base, which not only improves the convenience and safety of operation, but also saves space, increases comfort, and helps with the maintenance and cleaning of the equipment. This optimizes the newborn care environment, improves care efficiency, and ensures the durability and hygiene of the equipment.
[0019] 3. By setting a sliding rod and sliding seat inside the buffer plate, the endotracheal tube fixing mechanism can move a certain distance in the up, down and left and right directions. This can avoid the risk of the endotracheal tube being compressed, deviated or dislodged due to the newborn's head movement or other external forces. It also helps to prevent the endotracheal tube from being subjected to uneven pressure and reduces the occurrence of airway obstruction or ventilation difficulties. Attached Figure Description

Detailed Implementation
[0029] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.
[0030] like Figures 1-8 The endotracheal tube fixing device for neonatal care shown includes a base 1, two head limiting plates 2 are slidably mounted on the base 1, a retraction mechanism 3 is rotatably connected inside the base 1, an adjusting seat 4 is rotatably connected to the retraction mechanism 3, a top frame 5 is rotatably connected to the adjusting seat 4, an adjusting plate 6 is provided below the top frame 5, a buffer plate 7 is fixedly connected to one end of the adjusting plate 6, and an endotracheal 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 connected to both ends of one side of the mattress pressure plate 101. The other end of the sleeve rod 102 is slidably fitted through the inner wall of the base 1. A tension spring 103 is fixedly connected to the top of the sleeve rod 102, and the other end of the tension spring 103 is fixedly connected to the inner wall of the base 1. A storage slot 104 is provided on the base 1. The function of the tension spring 103 is to retract the mattress pressure plate 101 closer to 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 storage and transport are required, as it helps to reduce the space occupied and facilitates placement in backpacks, carriages, or other storage areas.
[0032] By setting a base 1 with a mattress pressure plate 101, the mattress pressure plate 101 is fixed by the mattress, so that when fixing the endotracheal tube for neonatal care, the endotracheal tube fixing mechanism 8 is suspended above the newborn's head without contacting the newborn's head. This avoids the pressure problems caused by neck straps or head fixation, so that the newborn's head and neck are not 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 newborn, which is conducive to the healthy development of the newborn.
[0033] like Figure 3 As shown, a sliding frame 201 is fixedly connected to one side of the head limiting plate 2, and 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 limiting plate 2. The head limiting plate 2 can fix the newborn's head in a suitable position, preventing involuntary head movement during intubation from affecting the accuracy of intubation. During intubation, head stability is crucial to ensure correct insertion of the endotracheal tube, avoiding intubation failure or incorrect insertion due to head shaking.
[0034] like Figure 4 As shown, the take-up and release mechanism 3 includes a motor 301, which is fixedly connected to the inner wall of the base 1. A bidirectional lead screw 302 is fixedly connected to the output end of the motor 301. The bidirectional lead screw 302 is rotatably connected to the inner wall of the base 1. Slider blocks 303 are threadedly connected to the outer walls of both ends of the bidirectional lead screw 302. Take-up and release rods 304 are rotatably connected to the sliders 303. The other end of the take-up and release rods 304 is rotatably connected to the adjusting seat 4. A sector gear 305 is fixedly connected to the end of the take-up and release rod 304 connected to the adjusting seat 4. The motor 301 drives the connected bidirectional lead screw 302 to rotate, so that the bidirectional lead screw 302 can drive the slider 303 to move. At this time, the slider 303 will lift the adjusting seat 4 through the take-up and release rods 304.
[0035] like Figure 5As shown, a worm gear 401 is rotatably connected to the bottom of the adjusting seat 4, and a transmission wheel 402 is fixedly connected to one end of the worm gear 401. The transmission wheel 402 meshes with the sector gear 305 for transmission.
[0036] like Figure 5 As shown, a rotating shaft 501 is fixedly connected to one end of the top frame 5. The rotating shaft 501 is rotatably connected to the adjusting seat 4. A worm gear 502 is fixedly connected to the bottom end of the rotating shaft 501. The worm gear 502 meshes with the worm 401 for transmission. The top frame 5 is slidably fitted to the inner wall of the storage groove 104. When the adjusting seat 4 moves upward, the sector 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, and the rotating shaft 501 can drive the connected top frame 5 to rotate.
[0037] like Figure 6 As shown, two symmetrically connected linkage assemblies 601 are rotatably mounted on the adjusting plate 6. The other end of each linkage assembly 601 is rotatably connected to the top frame 5. One of the linkage assemblies 601 has an electric actuator B602 rotatably connected to its upper end, and the other end of the electric actuator B602 is rotatably connected to the inner wall of the top frame 5. The electric actuator B602 drives the connected linkage assemblies 601 to rotate, causing the linkage assemblies 601 to lower the endotracheal tube fixing mechanism 8 to a suitable height.
[0038] like Figure 7 As shown, the inner walls of both the upper and lower ends of the buffer plate 7 are provided with sliding grooves 701. A sliding rod 702 is provided on the inner side of the buffer plate 7. Both ends of the sliding rod 702 are slidably engaged with the inner wall of the sliding groove 701. Springs A703 are fixedly connected to both the upper and lower ends of the sliding rod 702. 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 engaged on the sliding rod 702. Springs B705 are fixedly connected to both the upper and lower ends of the sliding seat 704. The other end of the spring B705 is fixedly connected to the sliding rod 702.
[0039] like Figure 8As shown, the endotracheal tube fixation mechanism 8 includes a fixing base 801, one end of which is fixedly connected to a slide 704. A clamping air bag 802 is fixedly connected to the inner wall of the middle part of the fixing base 801. An air pump 803 is fixedly connected to the fixing base 801, with the output end of the air pump 803 communicating with the input end of the clamping air bag 802. A transparent mouthpiece 804 is slidably fitted below the fixing base 801, and a rubber ring 805 is fixedly connected to the opening at the top of the transparent mouthpiece 804. The transparent mouthpiece 804 not only improves the visibility of the intubation process and reduces irritation and discomfort during intubation, but also effectively reduces the risk of infection, improves operational accuracy, and ensures a clear airway for the newborn. This enhances the safety, comfort, and efficiency of the nursing process, providing a better nursing environment for newborns. The rubber ring 805 typically has a certain degree of softness and elasticity, allowing it to adapt to endotracheal tubes of different sizes and providing a certain degree of compatibility. In this way, regardless of the size of the endotracheal tube used, the rubber ring 805 provides excellent fixation, ensuring smooth intubation every time. Inflation of the clamping cuff 802 evenly distributes pressure across the tracheal wall, reducing the risk of pressure injuries, airway inflammation, or other complications caused by the endotracheal tube. The uniform support provided by the clamping cuff 802 effectively reduces damage caused by localized pressure concentration or poor tube contact.
[0040] Working principle: When it is necessary to insert a tracheal tube into the mouth of a newborn for care, first pull down the mattress pressure plate 101 so that the mattress is placed between the mattress pressure 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 electric push rod A202 drives the head limiting plate 2 connected to the sliding frame 201 to move and limit the newborn's head.
[0041] Then, after the endotracheal tube is inserted into the oral cavity, the motor 301 drives the connected bidirectional lead screw 302 to rotate, so that the bidirectional lead screw 302 can drive the slider 303 to move. At this time, the slider 303 will lift the adjusting seat 4 through the retracting rod 304.
[0042] At the same time, when the adjusting seat 4 moves up, the sector gear 305 on the retracting rod 304 will drive the worm gear 401 connected to the transmission wheel 402 to rotate, so that the worm gear 401 can drive the rotating shaft 501 connected to the worm wheel 502 to rotate, so that the rotating shaft 501 can drive the connected top frame 5 to rotate above the newborn's head.
[0043] Then, the electric actuator B602 drives the connected linkage 601 to rotate, so that the linkage 601 drives the endotracheal tube fixing mechanism 8 to descend to a suitable height. Then, one end of the endotracheal tube passes through the rubber ring 805 on the transparent mouth mask 804 and passes out from the fixing seat 801. Then, the fixing seat 801 continues to move down, so that the transparent mouth mask 804 can be attached to the newborn's mouth.
[0044] Then, by using the air pump 803 to inject an appropriate amount of air into the clamping airbag 802, the clamping airbag 802 can inflate and clamp and fix the endotracheal tube.
