Description

Technical Field

[0001] The present invention relates to the field of medical devices, and more particularly, to a nasal plug fixing device for non-invasive assisted ventilation of newborns. Background Art

[0002] In the medical care of newborns, non-invasive assisted ventilation is an important means to help newborns with imperfect respiratory function maintain normal breathing.

[0003] Currently, most nasal plug fixing devices for non-invasive assisted ventilation of newborns on the market have significant defects in adapting to the individual differences of newborns. Most fixing devices adopt a design with preset sizes and lack a structure that can be flexibly adjusted according to the actual size of the newborn's head. For newborns with smaller heads, the fixing device is often too large, resulting in the cap body not being able to fit tightly to the head, making the nasal plug prone to displacement or even falling off. On the contrary, for newborns with larger heads, the size of the fixing device is too small, and forced wearing will make the cap body too tight, bringing great discomfort to the newborn. Long-term tight fixation not only easily causes skin damage to the newborn, such as indentations, redness, etc., but may also affect blood circulation, having a negative impact on the physical health of the newborn. In addition, the existing fixing devices have a relatively single fixing method and lack an effective fastening and adjustment mechanism. During the daily activities of newborns, such as head turning and limb twisting, the fixing device is very easy to loosen, thereby causing the position of the nasal plug to shift. Once the position of the nasal plug is improper, medical staff need to spend a lot of time readjusting it. In emergency situations, this may delay the treatment of the newborn and increase the treatment risk.

[0004] Therefore, a nasal plug fixing device for non-invasive assisted ventilation of newborns is proposed to solve the above problems. Summary of the Invention

[0005] 1. Technical Problems to be Solved

[0006] Aiming at the problems existing in the prior art, the purpose of the present invention is to provide a nasal plug fixing device for non-invasive assisted ventilation of newborns to solve the problems raised in the above background art.

[0007] 2. Technical Solutions

[0008] To solve the above problems, the present invention adopts the following technical solutions.

[0009] A non-invasive assisted ventilation nasal plug fixing device for newborns, comprising a cap body. A fixing sleeve is sewn below the outer wall of the cap body. A fastening rope is slidably connected inside the fixing sleeve. A moving block is slidably connected to the outer wall of the fastening rope. An extrusion block is arranged on one side of the moving block. Circular grooves corresponding to the fastening rope are arranged on one side of both the extrusion block and the moving block. A telescopic rod is fixedly connected inside the extrusion block. The output end of the telescopic rod is fixedly connected to one side of the moving block. A second spring is sleeved on the outer wall of the telescopic rod. The second spring is located inside the extrusion block. Both ends of the second spring are fixedly connected to the inside of the extrusion block and one side of the moving block respectively.

[0010] Further, a protection groove is formed on one side of the moving block. A rocker is rotatably connected inside the protection groove. A third spring is rotatably connected to one side of the rocker. One end of the third spring is rotatably connected inside the protection groove.

[0011] Further, a lifting block is slidably connected to one side of the moving block. A convex block is fixedly connected to one side of the lifting block. The convex block is located on one side of the rocker.

[0012] Further, a thick rope is fixedly connected to the outside of the cap body. A nasal mask is fixedly connected between the ends of the two thick ropes.

[0013] Further, a pull rope is slidably connected inside the thick rope. One end of the pull rope located inside the thick rope is fixedly connected to one side of the nasal mask. The other end of the pull rope passes through the thick rope and is located on one side of the cap body.

[0014] Further, a fixing tube is fixedly connected above the nasal mask. One end of the fixing tube is fixedly connected with a mounting head.

[0015] Further, a sliding block is slidably connected to the outer wall of the mounting head. Anti-slip patterns are formed on the surface of the sliding block.

[0016] Further, a spherical ball is slidably connected inside the mounting head. The four spherical balls are equidistantly distributed. The four spherical balls are all located inside a trapezoidal groove formed inside the mounting head.

[0017] Further, a first spring is fixedly connected to one side of the sliding block. The first spring is sleeved on the outer wall of the mounting head. One side of the first spring is fixedly connected to one side of the mounting head.

[0018] Further, a breathing tube is slidably connected inside the mounting head. A clamping groove is formed at the interface of the breathing tube. The spherical ball is clamped inside the clamping groove.

[0019] 3. Beneficial effects

[0020] Compared with the prior art, the advantages of the present invention are as follows:

[0021] (1) In this solution, this fixing device demonstrates excellent flexibility in adapting to newborns. The fixing sleeve sewn under the cap body, and the fastening rope slidably connected inside can freely slide according to the actual size of the newborn's head. Medical staff can easily adjust the tightness of the cap body by sliding the position of the moving block on the fastening rope. The corresponding circular groove provided on one side of the moving block and the extrusion block can firmly clamp the fastening rope under the coordinated action of the telescopic rod and the second spring, ensuring the stability of the adjusted position. Whether the newborn has a rounder or longer head shape, or a larger or smaller size, this flexible adjustment mechanism can achieve a close fit between the cap body and the head, effectively avoiding the displacement or detachment of the nasal cannula caused by improper fixation, and significantly improving the stability of the ventilation effect. For example, for a newborn with a smaller head, the moving block can be slid towards the cap body to shorten the effective length of the fastening rope, making the cap body fit the head more closely; while for a newborn with a larger head, the moving block is slid in the opposite direction to increase the effective length of the fastening rope to ensure that the cap body can be worn comfortably.

[0022] (2) In this solution, the fine adjustment of the nasal cannula position can be achieved through the thick rope fixedly connected to the outside of the cap body and the drawstring slidably connected inside it. Medical staff can pull the drawstring according to the facial features of the newborn to flexibly change the fitting degree between the nasal cannula and the newborn's nasal cavity and tie a knot. For example, for a newborn with a smaller face, tightening the drawstring can make the nasal cannula fit the nasal cavity more closely, reducing gas leakage and ensuring the stability of the ventilation effect; while for a newborn with a slightly larger face, the drawstring is loosened to make the nasal cannula fit the facial contour, ensuring the effectiveness of non-invasive assisted ventilation. This precise fitting mechanism greatly improves the applicability of the device to different newborn individuals, effectively avoiding the situation of insufficient ventilation or interruption caused by improper nasal cannula position, and providing continuous and stable oxygen support for newborns.

[0033] Embodiment 1

[0034] See also Figures 1-5A non-invasive auxiliary ventilation nasal congestion fixing device for neonates comprises a cap body 1, a fixing sleeve 13 is sewn below the outer wall of the cap body 1, a fastening rope 14 is slidably connected inside the fixing sleeve 13, a moving block 23 is slidably connected to the outer wall of the fastening rope 14, an extrusion block 26 is arranged on one side of the moving block 23, a circular groove corresponding to the fastening rope 14 is arranged on one side of the extrusion block 26 and the moving block 23, a telescopic rod 27 is fixedly connected inside the extrusion block 26, an output end of the telescopic rod 27 is fixedly connected to one side of the moving block 23, and a second telescopic rod 27 is sleeved on the outer wall of the telescopic rod 27 Spring 28, No. 2 spring 28 is located inside the extrusion block 26, two ends of the No. 2 spring 28 are respectively fixedly connected to the inside of the extrusion block 26 and one side of the moving block 23, a protective groove 3 is opened on one side of the moving block 23, a seesaw 29 is rotatably connected inside the protective groove 3, one side of the seesaw 29 is rotatably connected to a No. 3 spring 31, one end of the No. 3 spring 31 is rotatably connected to the inside of the protective groove 3, one side of the moving block 23 is slidably connected to a lifting block 24, one side of the lifting block 24 is fixedly connected to a protrusion 25, and the protrusion 25 is located on one side of the seesaw 29.

[0035] In this embodiment, the fixing device shows excellent flexibility in adapting to newborns. The fixing sleeve 13 sewn under the cap body 1 and the internal sliding connection fastening rope 14 can slide freely according to the actual size of the newborn's head. The medical staff can easily adjust the tightness of the cap body 1 by sliding the position of the moving block 23 on the fastening rope 14. The corresponding circular grooves set on one side of the moving block 23 and the extrusion block 26 can firmly clamp the fastening rope 14 under the coordinated action of the telescopic rod 27 and the second spring 28 to ensure the stability of the adjusted position, regardless of whether the head shape is round or not. For newborns with small, long, large or small heads, the flexible adjustment mechanism can be used to achieve a close fit between the cap body 1 and the head, effectively avoiding displacement or falling off of the nasal plug due to improper fixation, and significantly improving the stability of the ventilation effect. For example, for newborns with small heads, the moving block 23 can be slid toward the cap body 1 to shorten the effective length of the fastening rope 14, so that the cap body 1 fits the head better; and for newborns with large heads, the moving block 23 can be slid in the opposite direction to increase the effective length of the fastening rope 14, so as to ensure that the cap body 1 can be worn comfortably.

[0036] Dynamic adaptation to the head movement of the newborn: It is inevitable that the newborn's head will move during the treatment process. The present device can adapt well to these dynamic changes. When the newborn's head turns or shakes slightly, the combination of the fastening rope 14, the moving block 23 and the squeezing block 26 allows the cap body 1 to make corresponding fine adjustments to always maintain stable fixation of the nasal plug. For example, when the newborn's head turns to one side, the sliding fit between the fixing sleeve 13 and the fastening rope 14, and the adaptive adjustment of the fastening rope 14 by the moving block 23 and the squeezing block 26 can ensure that the cap body 1 will not produce excessive displacement due to the head movement, thereby maintaining the accurate position of the nasal plug in the nasal cavity.

[0037] Embodiment 2

[0038] Please refer to Figures 1-5 , a non-invasive assisted ventilation nasal plug fixing device for newborns. A thick rope 11 is fixedly connected to the outside of the cap body 1. A nasal mask 15 is fixedly connected between the ends of the two thick ropes 11. A pull rope 12 is slidably connected inside the thick rope 11. One end of the pull rope 12 located inside the thick rope 11 is fixedly connected to one side of the nasal mask 15. The other end of the pull rope 12 passes through one side of the thick rope 11 located at the cap body 1. A fixing tube 16 is fixedly connected above the nasal mask 15. One end of the fixing tube 16 is fixedly connected to a mounting head 17. A sliding block 19 is slidably connected to the outer wall of the mounting head 17. Anti-slip lines are provided on the surface of the sliding block 19. A spherical ball 18 is slidably connected inside the mounting head 17. The four spherical balls 18 are equally spaced. The four spherical balls 18 are all located inside a trapezoidal groove formed inside the mounting head 17. One side of the sliding block 19 is fixedly connected to a first spring 2. The first spring 2 is sleeved on the outer wall of the mounting head 17. One side of the first spring 2 is fixedly connected to one side of the mounting head 17. A breathing tube 21 is slidably connected inside the mounting head 17. A clamping groove 22 is provided at the interface of the breathing tube 21. The spherical ball 18 is clamped inside the clamping groove 22;

[0039] In this embodiment, through the thick rope 11 fixedly connected to the outside of the cap body 1 and the pull rope 12 slidably connected inside it, this device demonstrates excellent adaptability. In actual application scenarios, the facial features of newborns vary greatly. From premature babies with delicate and small faces to full-term newborns with relatively plump faces, it can achieve precise adaptation. For example, in a neonatal intensive care unit, when faced with a premature baby with a small facial contour, medical staff only need to gently pull the pull rope 12. The pull rope 12 slides inside the thick rope 11, driving the nasal mask 15 to gradually approach the nasal cavity until it fits tightly. This process can effectively reduce gas leakage, ensure stable ventilation effect, and the blood oxygen saturation of the newborn always remains within the normal range. For full-term newborns with slightly larger faces, reverse the operation to relax the pull rope 12. The nasal mask 15, driven by the thick rope 11, naturally adapts to their larger facial contours. The entire ventilation process is smooth and unobstructed, fully ensuring the effectiveness of non-invasive assisted ventilation. This precise adaptation mechanism greatly improves the applicability of the device to different newborn individuals, avoiding situations of insufficient ventilation or interruption caused by improper position of the nasal mask 15, and providing continuous and stable oxygen support for newborns;

[0040] The connection design of the fixing tube 16, the mounting head 17 and the breathing tube 21 above the nasal mask 15 is extremely ingenious. The four equally spaced spherical balls 18 inside the mounting head 17 in the trapezoidal groove are tightly clamped with the clamping groove 22 at the interface of the breathing tube 21, forming a stable connection structure. During the daily activities of newborns, including frequent head turning and large-scale limb twisting, the connection between the breathing tube 21 and the mounting head 17 always remains stable;

[0041] The separation operation of the breathing tube 21 from the mounting head 17 is extremely simple. When it is necessary to replace the breathing tube 21 for cleaning or maintenance, medical staff only need to gently push the sliding block 19. The sliding block 19 drives the relevant structure to move, causing the spherical ball 18 to disengage from the card slot 22, and the breathing tube 21 can be easily separated from the mounting head 17. Through actual testing, compared with the disassembly method of traditional fixing devices that requires tools and takes several minutes, the work efficiency is greatly improved. In emergency treatment scenarios, this convenience is particularly crucial, enabling the rapid replacement of the breathing tube 21 to ensure the ventilation of the newborn is not affected. Moreover, the overall structure of the device is reasonably designed, and the connection and disassembly methods between components are simple and easy to understand, facilitating the daily operation and maintenance of medical staff, effectively reducing the work intensity, improving the reliability of the device, and providing a strong guarantee for the smooth progress of non-invasive assisted ventilation treatment for newborns.

[0042] Working principle: The cap body 1 serves as the basic load-bearing part of the entire device. The fastening rope 14 inside the fixing sleeve 13 sewn on the lower part of its outer wall is the key to adapting to the size of the newborn's head. When it is necessary to wear the device, medical staff can adjust the circumference of the cap body 1 by sliding the position of the moving block 23 on the fastening rope 14. The moving block 23 and the circular groove on one side of the extrusion block 26 can firmly clamp the fastening rope 14 under the action of the telescopic rod 27 and the second spring 28. For example, for a newborn with a smaller head, push the moving block 23 closer to the cap body 1 to shorten the effective length of the fastening rope 14. Subsequently, under the elastic force of the second spring 28, the extrusion block 26 and the moving block 23 clamp the fastening rope 14, making the cap body 1 fit the head; conversely, for a newborn with a larger head, slide the moving block 23 in the opposite direction.

[0043] The thick rope 11 outside the cap body 1 is connected to the nasal mask 15. The drawstring 12 inside the thick rope 11 can further fine-tune the position of the nasal mask 15. Medical staff can change the telescopic length of the drawstring 12 in the thick rope 11 by pulling one end of the drawstring 12 on one side of the cap body 1, thereby adjusting the fitting degree between the nasal mask 15 and the newborn's nasal cavity. For example, if the newborn's face is narrower, tighten the drawstring 12 to make the nasal mask 15 closer to the nasal cavity; when the face is wider, loosen the drawstring 12.

[0044] The cap body 1 is made of soft and breathable medical silicone material, and the inner sponge cushion layer further enhances the comfort and pressure dispersion effect. This material combination reduces the friction with the newborn's skin, and the good air permeability prevents the head from feeling stuffy and uncomfortable, providing all-round protection for the delicate skin of the newborn.

[0045] The mounting head 17 at one end of the fixed pipe 16 above the nose mask 15 is used to connect the breathing tube 21. The four spherical balls 18 inside the mounting head 17 are evenly distributed in the trapezoidal groove. The clamping groove 22 at the interface of the breathing tube 21 is clamped with the spherical balls 18. When the breathing tube 21 is inserted, the sliding block 19 pushes the spherical balls 18 to slide in the trapezoidal groove until the clamping groove 22 is precisely clamped with the spherical balls 18, realizing the stable connection between the breathing tube 21 and the mounting head 17 and preventing it from falling off during ventilation.

[0046] The above is only a preferred specific embodiment of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, making equivalent replacements or changes, should be covered by the protection scope of the present invention.
