Description

Technical Field

[0001] The invention belongs to the technical field of medical equipment and relates to a neonatal vibration expectoration instrument. Background Art

[0002] In the neonatal department of the hospital, sputum blockage in the respiratory tract of newborns due to infection is a common situation. For example, a newborn was found to have congenital tracheal stenosis one week after birth. Sputum easily accumulated, leading to repeated respiratory blockage. Regular use of a vibrating expectorant helps loosen and clear sputum. Combined with postural drainage, it promotes sputum discharge. The frequency of newborn airway blockage is reduced, and the respiratory condition is stable, which buys time for subsequent surgical treatment. For example, a 28-week premature baby required long-term ventilator support two weeks after birth due to incomplete lung development and repeated infections. The problem of sputum accumulation was serious. Using a vibrating expectorant three times daily helps clear sputum deep in the respiratory tract. Combined with nebulization and suctioning to ensure a clear airway, regular assessment of sputum volume and properties, and adjustments to treatment plans, the problem of sputum accumulation in newborns has been alleviated, ventilator support parameters have gradually decreased, and lung infections have been controlled. For example, a full-term newborn developed pneumonia due to infection, resulting in increased respiratory secretions, thick sputum, and difficulty coughing up. Medical staff used a vibrating expectorant, combined with nebulization and inhalation of saline to dilute the sputum, and then used the vibrating expectorant to assist in expectoration. The sputum was gradually cleared, respiratory sounds improved, and the infection was controlled. Therefore, a vibrating expectorant is a relatively common assistive expectoration device.

[0003] Currently, the existing vibrating expectoration device includes a vibrating head and a driving structure. The driving mechanism drives the vibrating head to vibrate, physically vibrating the back of the newborn to assist the newborn in expectoration.

[0004] However, since the size of newborns varies from the extremely small size of premature babies to the larger size of full-term babies, and the size of the vibration head cannot be adjusted, it is easy for the size of the vibration head to not match the size of the newborn, resulting in the vibration head being unable to accurately act on the target area, reducing the expectoration effect.

[0024] like Figure 4 As shown, the transmission assembly includes a transmission block 31, a first transmission rod 21, a first elastic member 24 and a first connecting rod 36. The transmission block 31 is arranged at the bottom of the first cavity 7 and is located near the open end of the air cylinder 29. The transmission block 31 is slidably connected to the bottom of the first cavity 7. The first transmission rod 21 is arranged between the transmission block 31 and the air cylinder 29.

The second cavity 8 is opened inside the vibrating head 6 and is located near the bottom of the first cavity 7. The end of the conveying cylinder 20 passes through the bottom of the first cavity 7 and is located in the second cavity 8. The second piston 23 is arranged in the conveying cylinder 20 and is located between the multiple connecting pipes 30 and the second cavity 8. The cam 27 is arranged in the second cavity 8 and is located near the conveying cylinder 20. The cam 27 is arranged at a position where the conveying cylinder 20 is away from the first cavity 7. The motor 28 is arranged in the second cavity 8. The output end of the motor 28 is connected to the cam 27. The second transmission rod 39 is arranged between the cam 27 and the conveying cylinder. The second piston 23 is reciprocated up and down in the conveying cylinder 20 by the second transmission rod 39, so that the gas in the airbag 12 vibrates, thereby causing the end of the airbag 12 to vibrate.

[0026] like Figure 2 、 Figure 6 As shown, a plurality of limiting plates 40 are evenly arranged around the airbag 12 in the through hole 9, and the plurality of limiting plates 40 correspond one to one with the plurality of clamping blocks 18. The end of each limiting plate 40 is slidably connected with the corresponding clamping block 18, so that each limiting plate 40 can slide on the corresponding clamping block 18. The side of each limiting plate 40 is connected to the side of the airbag 12, and the side of the airbag 12 near the end is clamped by the plurality of limiting plates 40. The part of the airbag 12 clamped by the plurality of limiting plates 40 is the vibration end, so that the size of the vibration end of the airbag 12 can be better adjusted by the plurality of limiting plates 40, and further adapted to newborns of different sizes.

[0027] like Figure 6 、 Figure 7As shown, a first slide groove 32 is provided at the top of the first cavity 7 near each clamping block 18, and a first slider 34 is provided in the first slide groove 32.

The cross-section of the first slide groove 32 and the corresponding first slider 34, and the cross-section of the second slide groove 33 and the corresponding second slider 35 are trapezoidal shapes that match each other, so as to prevent the first slider 34 from falling out of the first slide groove 32 and the second slider 35 from falling out of the second slide groove 33.

[0028] like Figure 1 、 Figure 3 、 Figure 6 As shown, the side of the airbag 12 close to the multiple clamping blocks 18 is a wavy structure, and the side of the airbag 12 close to the support plate 19 and the side away from the support plate 19 are both made of elastic material. The wavy structure allows the airbag 12 to stand between the multiple clamping blocks 18, while also ensuring the elasticity of the airbag 12, so that the length and width of the airbag 12 can increase when inflated, and the length and width can decrease when deflated. The two ends of the airbag 12 are made of elastic material, so that the side of the airbag 12 close to the support plate 19 and the side away from the support plate 19 can change with the change of the cross-section of the airbag 12. At the same time, when the airbag 12 is quickly inflated and deflated, the vibration end can be driven to bulge upward and then reset, producing an up and down vibration effect.

[0029] like Figure 1 As shown, scale lines are set around the circumference of the side of the vibration head 6 near the adjustment ring 10, and arrows are set near the scale lines on the adjustment ring 10. By rotating the adjustment ring 10, the arrow on it is driven to rotate, and the position of the arrow pointing to the scale line is determined to determine the increase or decrease in the volume of the space formed between the multiple clamping blocks and the inflation and deflation amounts of the airbag, thereby further accurately adjusting the size of the airbag.

[0030] like Figure 8As shown, the present invention provides a neonatal vibrating sputum removal instrument, which also includes a mobile base 1. The lower part of the mobile base 1 is evenly provided with a plurality of universal wheels around its circumference for easy free movement. The upper part of the mobile base 1 is provided with a storage box 3, and the opening of the storage box 3 is upward. An electric telescopic rod 2 is vertically provided between the mobile base 1 and the storage box 3, so that the height of the storage box 3 can be adjusted by the electric telescopic rod 2, so that commonly used items can be placed in the storage box 3. A support column 4 is vertically provided in the storage box 3, and the lower end of the support column 4 is fixedly connected to the storage box 3. A controller 5 is provided at the upper end of the support column 4, and a vibration head 6 is hung on the side of the controller 5. The motor 28 is electrically connected to the controller 5, and the start and stop and speed of the motor 28 are controlled by the controller 5, thereby controlling the vibration frequency of the start of the vibration head 6 to adapt to different newborns.

[0031] Working principle: When in use, the size of the vibration head 6 is adjusted according to the difference of the newborn, that is, the adjustment ring 10 is rotated, and the adjustment ring 10 drives the inner gear ring 14 to rotate through the two connecting blocks 13. The inner gear ring 1 drives multiple gears 15 to rotate synchronously, and the multiple gears 15 drive the multiple racks 14 to move. The multiple racks 14 drive the multiple clamping blocks 18 to move. Each clamping block 18 moves along the corresponding first slide groove 32 to adjust the volume of the space formed between the multiple clamping blocks 18.

[0032] At the same time, when the rack 14 moves, the transmission block 31 is driven to move through the first connecting rod 36, and the transmission block 31 drives the first piston 22 to move back and forth in the air cylinder 29 through the first transmission rod 21. The airbag 12 is inflated and deflated through multiple connecting tubes 30 and the conveying tube 20, so that the volume of the space formed between the multiple clamping blocks 18 and the volume of the gas in the airbag 12 can be adjusted synchronously, thereby adjusting the volume of the airbag 12.

[0033] When the multiple clamping blocks 18 move, the multiple limiting plates 40 are driven to move, so that the distance between the multiple limiting plates 40 changes, which helps adjust the size of the airbag 12 at the inner end of the through hole 9 to adapt to the different body shapes of newborns.

[0034] After the adjustment of the vibration head 6 is completed, the starting motor 28 is started, and the motor 28 drives the cam 27 to rotate. The roller 26 moves along the edge of the cam 27, driving the roller 26 to move upward and reset under the action of the second elastic member 25. The roller 26 drives the second piston 23 to move up and down in the conveying cylinder 20 through the second transmission rod 39, so that the airbag 12 is quickly inflated and deflated, so that the vibration end of the airbag 12 located at the through hole 9 vibrates up and down, physically vibrates the back of the newborn, and assists the newborn in expectoration.

[0035] It will be understood that the present invention is described by way of some embodiments, and it will be appreciated by those skilled in the art that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention.
