Description
Technical Field
[0001] This utility model relates to the field of respiratory therapy sputum expectoration device technology, and mainly to a respiratory sputum expectoration device with adjustable vibration frequency. Background Technology
[0002] With changes in modern technology and lifestyles, worsening air quality, and an accelerating aging population, the causes of lung diseases have increased, leading to various chronic lung diseases such as chronic obstructive pulmonary disease, asthma, and emphysema. In some cases of acute lung diseases such as cough, influenza, tracheitis, or bronchitis, the airways of some patients become blocked by phlegm. The inability to expel phlegm often results in coughing, difficulty breathing, and shortness of breath, severely reducing the patient's quality of life, weakening lung function, and increasing susceptibility to bacteria and viruses. When patients cannot cough it up on their own, suction devices are often used to remove it.
[0003] Most existing breathing trainers use a ball-head structure for adjustment, where the ball head is rotated open during exhalation. Insufficient expiratory strength or an off-center angle during exhalation will not achieve the desired training effect, requiring correct user operation and making them inconvenient to use. Alternatively, a seesaw structure can be used for expiratory training, adjusting the flow area of the valve body to regulate the expiratory strength required to open the other end of the seesaw. However, this structure limits the oscillation frequency setting, which can negatively impact sputum expectoration during expiratory airway resistance training. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a respiratory expectorant with a settable vibration frequency. The technical problem it aims to solve is that the pressure component exerts downward pressure on the valve body inside the fourth connector, and the pressure is relatively stable. When the exhalation intensity is at its maximum, the valve body is opened, generating a large airflow pressure that forms a vibration wave inside the patient's airway.

[0028] See Figures 1 to 2 The figure shows a sputum expectoration device with a set vibration frequency, including a sputum expectoration device body 10, a mouthpiece 12, and a first connector 21. The sputum expectoration device body is arranged horizontally, the mouthpiece 12 is located at one end along the length of the sputum expectoration device body, and the first connector 21 is vertically arranged at the lower left part of the sputum expectoration device body. The first connector 21 is used to introduce fresh air into the sputum expectoration device body 10 from the outside. It also includes a fourth connector 25, a sputum expectoration component, a pressure component, and an outer cover 60. The fourth connector 25 is vertically arranged at the upper middle part of the sputum expectoration device body. The upper part of the pressure component is located inside the fourth connector 25, and the lower part of the pressure component is located inside the sputum expectoration device body 10, directly below the fourth connector 25. The sputum expectoration component is used to block or open the airflow channel inside the fourth connector 25. The outer cover 60 is detachably fitted onto the top of the sputum expectoration device body 10, and the sputum expectoration component is located inside the outer cover 60.
[0029] The upper and lower parts of the pressure component of this utility model are respectively located inside and directly below the fourth connector 25. The pressure component exerts downward pressure on the valve body inside the fourth connector 25, and the pressure is relatively stable. During the user's breathing process, the airflow channel inside the fourth connector 25 is opened or blocked. When the exhalation intensity is at its maximum, the valve body is opened. A large airflow pressure is generated, forming a vibration wave inside the patient's airway. The airflow pressure changes continuously through the opening and closing of the valve. The vibration causes the sputum in the airway to shift, making it easier for the patient to cough up the sputum.
[0030] In this preferred embodiment, the sputum suction assembly includes an air valve body, a vibrating element, a left positioning element, and a right positioning element. The outer circumferential surface of the middle part of the air valve body matches the diameter of the internal through hole of the fourth connector 25. The bottom of the left positioning element is located at the top left end of the sputum suction device body 10, and the left positioning element is used to install and position the left end of the vibrating element. The left end of the right positioning element is located at the top right end of the air valve body, and the right positioning element is used to install and position the right end of the vibrating element at the top left end of the air valve body.

The valve body includes a frustum head 41, a first magnet 42, and an anti-detachment plate 43. The upper part of the frustum head 41 is shaped like a frustum of a cone, and the lower part is shaped like a hemisphere. The outer wall of the upper part of the frustum head 41 is tightly fitted to the inner wall of the through hole of the fourth connector 25. The first magnet 42 is movably disposed inside the frustum head 41, and the anti-detachment plate 43 is horizontally disposed on the top outer periphery of the frustum head 41.
[0032] Furthermore, the pressure assembly includes a first magnet 42, a second inner cylinder 32, and a second magnet 33. The second inner cylinder 32 is coaxially disposed directly below the fourth connector 25 and is radially installed at the bottom center of the sputum expectorant body 10. The second magnet 33 is fixedly disposed at the inner bottom of the second inner cylinder 32. The second magnet 33 is used to approach the first magnet 42 to generate an attractive force, thereby providing a downward pressing force to the conical head 41.
[0033] The valve body has a left positioning component and a right positioning component at both ends. When the user breathes into the mouthpiece 12, the valve body and the left end of the right positioning component are gradually raised, effectively preventing the valve body from being pushed open and falling out. The pressure component includes a first magnet 42 and a second magnet 33. The attraction between the pair of magnets serves as the resistance to opening the valve body during exhalation, resulting in relatively stable pressure and good exhalation training effect.
[0034] In this preferred embodiment, the left positioning component includes a left positioning platform 51, a left fastening block 52, two left guide posts 54, and a left buckle 53. The left positioning platform 51 is horizontally disposed at the top left end of the sputum suction device body 10. The left end of the left positioning platform 51 is hinged to the left fastening block 52, and the left end of the left fastening block 52 is provided with a left buckle 53. The left fastening block 52 rotates clockwise to fasten the left end of the vibrator onto the left positioning platform 51. The two left guide posts 54 are vertically disposed on the top surface of the left positioning platform 51, and the two left guide posts 54 are disposed in the radial direction of the sputum suction device body.
[0035] Furthermore, the right positioning component includes a right positioning platform, a right fastening block 55, two right guide posts, and a right latch 56. The right positioning platform is horizontally positioned at the right end of the anti-detachment plate 43 of the air valve body. The left end of the right positioning platform is hinged to the right fastening block 55. The bottom of the right latch 56 is vertically fixed at the right end of the right fastening block 55. The right fastening block 55 rotates counterclockwise to fasten the right end of the vibrator onto the right positioning platform. The two right guide posts 57 are vertically positioned on the left and right sides of the anti-detachment plate 43 of the air valve body, respectively. The two left guide posts 54 and the right guide posts 57 are all positioned in the radial direction of the sputum expectoration body. The right positioning platform is the anti-detachment plate 43.
[0036] In this preferred embodiment, the vibrating element is a horizontally arranged elastic sheet 58; the height of the left guide post 54 on the left is less than the height of the right guide post 54, and the height of the right guide post 57 is less than the height of the left guide post 54; the left end of the elastic sheet 58 has two left guide holes respectively installed on the two left guide posts 54, and the right end of the elastic sheet 58 has two right guide holes respectively installed on the two right guide posts 57. Specifically, the longitudinal section of the left fastening block 52 is π-shaped; in another embodiment, one left guide post 54 and one right guide post 57 may be provided.
[0037] Furthermore, the materials used for the elastic sheet 58 include, but are not limited to, metals, alloys, polymers, and plastics. All materials that can meet its functional requirements are acceptable and fall within the protection scope of this utility model.
[0038] Furthermore, the length of the elastic sheet is 55-65 mm, and the vibration frequency of the elastic sheet is 18-38 Hz / second. Specifically, the vibration frequency of the elastic sheet is preferably 16-40 Hz, as a oscillation frequency of 16-40 Hz is beneficial for the directional oscillation of bronchial / tracheal cilia to propel sputum from the small airways to the central airways, making it easier to cough up;
[0039] In a preferred embodiment, the length of the elastic sheet is 55-65 mm, and the vibration frequency of the elastic sheet is 18-38 Hz / second; when the length of the elastic sheet is 70-80 mm, the vibration frequency of the elastic sheet is 16-25 Hz / second. For elastic sheets of the same material, shorter lengths result in shorter strokes and durations of single vibrations, and shorter elastic sheets have higher vibration frequencies. The vibration frequency is adjusted by changing the length of the elastic sheet, and the required frequency is achieved by measuring the vibration frequency using a vibration frequency tester.
[0040] The above-mentioned vibrating component is designed as an elastic sheet 58. The elastic sheet 58 has a certain degree of elasticity when oscillating, which facilitates the appropriate adjustment of the oscillation angle and provides appropriate buffering force. The inner left guide post 54 and right guide post 57 are both higher than the outer ones. The left latching block 52 and right latching block 55 respectively prevent the elastic sheet 58 from being dislodged from the left guide post 54 and right guide post 57 during oscillation. The left guide post 54 and right guide post 57 have good guiding effect. The left end of the elastic sheet 58 is connected to the left guide post 54, and the right end is connected to the right guide post 57 in a manner similar to a hinge, but the hinge point is not fixed, that is, it slides up and down along the left guide post 54 and right guide post 57 respectively.
[0041] In this preferred embodiment, the inner wall of the left end of the outer cover 60 is provided with a mating protrusion 61, and the inner wall of the right end is provided with a snap-fit platform 63. The outer wall of the left end of the sputum suction device body 10 is provided with a mating groove 62, and a snap-fit block 64 is vertically arranged at the top center. The mating protrusion 61 abuts in the mating groove 62, and the buckle at the top right end of the snap-fit block 64 snaps into the top surface of the snap-fit platform 63. Specifically, a plurality of ventilation holes 65 are evenly spaced through the top panel of the outer cover 60.
[0042] The left part of the outer cover 60 is attached to the top left of the sputum suction device body 10, and the right part is snapped into the top of the sputum suction device body 10. The connection is secure and easy to disassemble.
[0043] Furthermore, a first one-way valve 22 is provided inside the first connector 21, and the first one-way valve 22 is open from bottom to top.
