Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and more specifically, to a multifunctional tracheotomy adapter. Background Technology
[0002] The multi-functional tracheostomy adapter is a device used in medical emergency and nursing care, primarily for airway management in patients after tracheostomy. It provides multiple functions, such as connecting to ventilators, suction devices, and oxygen supply, ensuring airway patency and respiratory support for the patient.
[0003] The diameter of common ventilator tubing is smaller than the diameter of the protrusion at the tip of the cannula in existing technology. When connecting the existing cannula to the ventilator tubing, it is necessary to replace it with a tracheostomy cannula with a smaller diameter in order to use the ventilator smoothly. At the same time, patients with tracheostomies need to close the cannula to make a sound. When using traditional adapters, medical staff need to be present to change the adapters to be compatible, which is inconvenient for patients to operate alone and reduces the efficiency of adapter use. Utility Model Content
[0004] The purpose of this invention is to provide a multifunctional tracheotomy adapter to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides a multifunctional tracheotomy adapter, comprising a connector body. A first sleeve is fixedly connected to the top of the connector body, and the connector body communicates internally with the first sleeve. A second sleeve is fixedly connected to the bottom of the connector body, and the second sleeve communicates internally with the connector body. The opening diameter of the first sleeve is smaller than the opening diameter of the second sleeve. A knob is rotatably connected to the top of the connector body, located on one side of the outer wall of the first sleeve. An adjustment plate is fixedly connected to the bottom of the knob, with the end of the adjustment plate away from the knob located below the bottom opening of the first sleeve. An auxiliary fixing mechanism is provided at the bottom of the top of the connector body and on one side of the adjusting plate. The auxiliary fixing mechanism includes a support block fixedly connected to the bottom of the top of the connector body. A square groove is opened inside the bottom of the support block. Two support rods are symmetrically slidably connected through the inner wall of the square groove. A support spring is fixedly connected to the end of each support rod away from the square groove. The end of each support spring near the square groove is fixedly connected to the outer wall of the support block. A pressure block is fixedly connected to the end of each support rod inside the square groove. A snap-fit block is fixedly connected to the bottom of the adjusting plate near the support block. The snap-fit block is inserted into the square groove.
[0006] As a further improvement to this technical solution, the outer contours of both pressure blocks are right-angled trapezoids, and the outer contour of the end of the snap-fit block away from the bottom of the adjustment plate is an isosceles trapezoid. The outer walls of both pressure blocks and the outer wall of the isosceles trapezoidal end of the snap-fit block are rough surfaces, and the two pressure blocks and the snap-fit block are inserted and fitted together.
[0007] As a further improvement to this technical solution, a sealing ring is fixedly connected to the top of the end of the adjustment plate away from the knob, and the diameter of the sealing ring is larger than the diameter of the bottom opening of the first sleeve.
[0008] As a further improvement to this technical solution, the first sleeve is made of hard plastic, the second sleeve is made of soft rubber, and multiple anti-slip textures are evenly distributed on the outer wall of the top of the knob to increase the friction between the finger and the knob.
[0009] As a further improvement to this technical solution, a vertical rod is fixedly connected to the top of the bottom of the connector body, a rubber slide rail is fixedly connected to the top of the vertical rod, and a sliding block is fixedly connected to the bottom of the adjusting plate near the rubber slide rail, the sliding block being slidably connected to the top of the rubber slide rail.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0011] This multi-functional tracheostomy adapter features a first-stage cannula made of hard plastic and a second-stage cannula made of soft rubber at the top and bottom of the connector body, respectively. This allows the first-stage cannula to connect to the ventilator tubing without the need for a smaller-diameter post-processing cannula, enabling connection to the ventilator without replacing the first-stage cannula. The second-stage cannula is inserted into the protrusion at the top of the internal tubing, facilitating breathing and speaking for tracheostomy patients. Furthermore, the adjustment plate can be closed and the bottom opening of the first-stage cannula can be opened via a knob, allowing the patient to switch between breathing and speaking functions. This also facilitates independent operation by the patient and improves the efficiency of the adapter.
[0012] By setting up an auxiliary fixing mechanism, the two pressure blocks are reset and simultaneously clamp and fix one end of the isosceles trapezoid of the snap-fit block, making the adjustment plate more stable when it is below the bottom opening of the No. 1 sleeve. This prevents the adjustment plate from separating from the bottom opening of the No. 1 sleeve due to vibrations caused by the patient moving their head and neck. At the same time, the sealing ring improves the sealing effect, so that the opening of the No. 1 sleeve is completely closed, thereby improving the patient's voice performance.

[0022] Example 1
[0023] Please see Figures 1-5As shown, this embodiment provides a multifunctional tracheostomy adapter, including a connector body 1. A first sleeve 2 is fixedly connected to the top of the connector body 1, and the connector body 1 communicates internally with the first sleeve 2. A second sleeve 3 is fixedly connected to the bottom of the connector body 1, and the second sleeve 3 communicates internally with the connector body 1. The opening diameter of the first sleeve 2 is smaller than the opening diameter of the second sleeve 3. The first sleeve 2 is made of hard plastic, and the second sleeve 3 is made of soft rubber. The first sleeve 2 and the second sleeve 3 are respectively provided at the top and bottom of the connector body 1. Firstly, the first sleeve 2, made of hard plastic, is inserted into the ventilator tubing, allowing the first sleeve 2 to communicate with the ventilator tubing. This eliminates the need to use the smaller diameter first sleeve 2 after processing, achieving the goal of connecting to the ventilator without replacing the first sleeve 2, thus improving the ease of use of the device. Subsequently, the second sleeve 3, made of soft rubber, is inserted into the protrusion at the top of the internal tube, completing the connection between the connector body 1 and the patient's trachea, facilitating subsequent breathing and speech for the tracheostomized patient. A knob 31 is rotatably connected to the top of the connector body 1 and to one side of the outer wall of the first cannula 2. An adjustment plate 32 is fixedly connected to the bottom of the knob 31, with the end of the adjustment plate 32 away from the knob 31 located below the bottom opening of the first cannula 2. When the user rotates the knob 31 counterclockwise, the knob 31 rotates synchronously with the adjustment plate 32. When the adjustment plate 32 rotates to below the bottom opening of the first cannula 2, it closes the bottom opening of the first cannula 2. At this time, the first cannula 2 is not connected to the inside of the connector body 1, and the patient can speak normally. When the knob 31 is rotated clockwise, the adjustment plate 32 is removed from the bottom opening of the first cannula 2, and the first cannula 2 is reconnected to the inside of the connector body 1, allowing the patient to breathe through the ventilator. This realizes the switching between speaking and breathing functions, facilitates independent operation by the patient, and improves the efficiency of the adapter.An auxiliary fixing mechanism 4 is provided at the top bottom of the connector body 1 and on one side of the adjusting plate 32. The auxiliary fixing mechanism 4 includes a support block 41 fixedly connected to the top bottom of the connector body 1. A square groove 42 is opened inside the bottom end of the support block 41. Two support rods 43 are symmetrically slidably connected through the inner wall of the square groove 42. A support spring 44 is fixedly connected to the end of each support rod 43 away from the square groove 42. The end of each support spring 44 near the square groove 42 is fixedly connected to the outer wall of the support block 41. 43 is located inside the square groove 42, with one end fixedly connected to a pressure block 45. A snap-fit block 46 is fixedly connected to the bottom of the adjusting plate 32 near the support block 41. The snap-fit block 46 engages with the square groove 42. The outer contours of both pressure blocks 45 are right-angled trapezoids, and the outer contour of the bottom end of the snap-fit block 46 away from the adjusting plate 32 is an isosceles trapezoid. The outer walls of both pressure blocks 45 and the outer wall of the isosceles trapezoidal end of the snap-fit block 46 are rough surfaces, which increases friction and makes the contact between the snap-fit block 46 and the pressure blocks 45 more secure. The pressure block 45 and the locking block 46 are engaged. When the adjusting plate 32 rotates counterclockwise and approaches the support block 41, the locking block 46 gradually inserts into the square groove 42. The outer walls on both sides of the isosceles trapezoidal end of the locking block 46 contact the inclined surface of the pressure block 45, causing the pressure block 45 to slide on the inner wall of the square groove 42 after being squeezed, while simultaneously squeezing the support spring 44. After the adjusting plate 32 rotates to its position, the rebound action of the support spring 44 causes the two pressure blocks 45 to reset, and simultaneously compresses the isosceles trapezoidal end of the locking block 46. It serves to clamp and fix the adjustment plate 32, making it more stable when it is located below the bottom opening of the first sleeve 2. It will not cause the adjustment plate 32 to separate from the bottom opening of the first sleeve 2 due to vibration caused by the patient moving their head and neck. A sealing ring 51 is fixedly connected to the top of the end of the adjustment plate 32 away from the knob 31. The diameter of the sealing ring 51 is larger than the diameter of the bottom opening of the first sleeve 2. At the same time, the sealing ring 51 improves the sealing effect, so that the opening of the first sleeve 2 is completely closed, thereby improving the patient's voice performance.
[0024] Multiple anti-slip grooves are evenly distributed on the outer wall of the top of the knob 31 to increase the friction between the fingers and the knob 31. A vertical rod 61 is fixedly connected to the top of the bottom of the connecting body 1, and a rubber slide rail 62 is fixedly connected to the top of the vertical rod 61. A sliding block 63 is fixedly connected to the bottom of the adjusting plate 32 near the rubber slide rail 62. The sliding block 63 is slidably connected to the top of the rubber slide rail 62. The vertical rod 61 can support and fix the rubber slide rail 62. When the adjusting plate 32 slides clockwise, the sliding block 63 slides synchronously on the top of the rubber slide rail 62, which has a damping effect. This makes the sliding of the adjusting plate 32 linear in both directions, improving the stability of use and preventing the adjusting plate 32 from rotating when the knob 31 is not rotated, thus improving the safety of the patient's independent operation.
