Description

Technical Field

[0001] The utility model relates to the technical field of artificial airways, in particular to an artificial airway conversion joint. Background Art

[0002] An artificial airway is a medical device used to maintain or assist the patient's respiratory function. When the patient is unable to breathe independently or has insufficient respiratory function, the artificial airway can support the patient's breathing by delivering oxygen and exhaled carbon dioxide. Since tracheotomy patients need to use a tracheal tube for oxygen inhalation and a nebulizer for nebulization, the patient needs oxygen inhalation and nebulization treatment during offline observation and after tracheotomy. However, after the tracheal tube is taken offline, the patient often suffers from hypoxia during the replacement of the nebulizer and oxygen tube. The tracheotomy nebulizer used by tracheotomy patients is not convenient for medical staff to operate and care, and the patient will suffer from hypoxia when clearing sputum.

[0003] In the prior art, for example, the Chinese patent number CN214912177U, "An artificial airway conversion joint", comprises: an artificial airway mask joint body, the artificial airway mask joint body is in the shape of a hollow cylinder as a whole, the side wall of the artificial airway mask joint body is provided with an assembly hollow column connected to the hollow part of the artificial airway mask joint body; an assembly cover plate and a locking assembly, and the assembly cover plate is sealed to the assembly hollow column by the locking assembly. Although this technology can reduce the oxygen disconnection during tracheotomy care and facilitate the operation and care of medical staff by connecting the assembly hollow column to the artificial airway mask joint body, this technology is not practical. There are still some defects during use: First, when the patient uses the suction connector body to suction sputum, since the atomization connector body is connected to the entire connector body, part of the sputum will remain in the atomization connector body during suction, causing the sputum to reflux when the atomization connector body is used subsequently, thereby affecting the normal use of the atomizer, and also causing the patient to have sputum stuck problems. Secondly, when the patient uses the atomizer for atomization, since the suction tube is connected to the entire connector body, gas flows out of the suction tube during atomization, thereby affecting the atomization effect and reducing the drug inhalation effect.

[0033] In this embodiment, Figure 5 as well as Figure 8The first and second slide grooves 31 are adapted to each other. Example

[0034] This embodiment provides an artificial airway conversion joint, such as Figure 2 as well as Figure 5 As shown, the difference from Example 1 is that a limit assembly is provided below the swivel 4, and the limit assembly includes a first elastic member, a slider 13 and a slide box 12. The slide box 12 is circumferentially arranged on the side wall of the suction tube 3 along the rotation direction of the swivel 4. The slider 13 is arranged in the slide box 12 and is slidably connected to the slide box 12. One end of the first elastic member is fixed to the swivel 4, and the other end of the first elastic member is fixed to the slider 13. A connecting bolt is provided on the slider 13, and the first elastic member is fixed to the slider 13 by the connecting bolt, as shown in FIG. Figure 7 As shown, two sloped blocks 14 are symmetrically fixed to the bottom of the sliding box 12, and the slider 13 slides on the two sloped blocks 14. The shape of the slider 13 matches the two sloped blocks 14, and both ends of the two sloped blocks 14 are provided with a slope, so that the bottom of the sliding box 12 forms a slope along the sliding direction of the slider 13; the swivel 4 is limited by setting a limit assembly, and the slider 13 is connected to the swivel 4 through a first elastic member. When the swivel 4 is rotated, the slider 13 rotates with the swivel 4, and a slope is formed along the sliding direction of the slider 13 through the bottom of the sliding box 12, so that the slider 13 is limited when it slides to the lowest point in the sliding box 12, prompting the slider 13 to be stuck at the lowest point of the sliding box 12, thereby avoiding the sliding of the baffle 7 due to accidental rotation of the swivel 4.

[0035] In this embodiment, Figure 1As shown, one end of the nebulizer tube 2 and the sputum suction tube 3 connected to the connector body 1 is trumpet-shaped, which can improve the gas circulation efficiency, reduce resistance, and improve the treatment effect. The ends of the nebulizer tube 2, the oxygen inhalation tube 30 and the sputum discharge tube are all threadedly connected with caps; by providing the caps, the nebulizer tube 2, the oxygen inhalation tube 30 and the sputum discharge tube can be kept clean when not in use, preventing external dirt from entering the device.

[0036] In this embodiment, Figure 1 and Figure 5 As shown, a guide block 27 is provided on the side wall of the swivel 4 at the fixed connection with the first elastic member, and a positioning block 28 is provided on the slide box 12 for cooperating with the guide block 27 to observe the rotation angle of the swivel 4 relative to the suction tube 3. The guide block 27 and the positioning block 28 are provided, and the rotation position of the swivel 4 relative to the suction tube 3 can be located, thereby confirming whether the interior of the suction tube 3 is closed. Different marks can be set at different positions of the slide box 12 to quickly confirm whether the interior of the suction tube 3 is closed.

[0037] When using this device, remove the caps on the sputum discharge tube, the nebulizer tube 2 and the oxygen inhalation tube 30, and connect the sputum discharge tube, the nebulizer tube 2, the oxygen inhalation tube 30 and the plug-in tube 29 on the connector body 1 to the sputum suction device, the nebulizer, the oxygen inhalation machine and the patient respectively. When performing sputum suction on the patient, observe the positions of the guide block 27 and the positioning block 28 to ensure the communication between the sputum suction tube 3 and the connector body 1, then check the positioning mechanism and the isolation component to ensure that the passages between the nebulizer tube 2 and the connector body 1 and between the oxygen inhalation tube 30 and the connector body 1 are in a closed state. At this time, perform sputum suction on the patient to prevent sputum from entering the nebulizer tube 2 and the oxygen inhalation tube 30. When performing oxygen and nebulizer on the patient When the swivel 4 is rotated, the swivel 4 and the fixing ring 6 rotate relative to each other, and the baffle 7 slides under the action of the swivel 4 and the fixing ring 6. The baffles 7 slide and gradually form a whole flat plate, blocking the circular holes in the swivel 4 and the fixing ring 6, so that the passage between the suction tube 3 and the joint body 1 is in a closed state. In this process, the slider 13 rotates with the swivel 4 under the connection of the first elastic member, and the slider 13 slides in the slide box 12, and the height first increases and then decreases until it is at the lowest point in the slide box 12. At this time, the baffles 7 just form a whole flat plate, so that the passage between the suction tube 3 and the joint body 1 is in a closed state. When the suction tube 3 and the joint body 1 need to be opened, When the passage between the joint body 1 is closed, the swivel ring 4 can be rotated in the opposite direction. After ensuring that the passage between the suction tube 3 and the joint body 1 is in a closed state, the pull rod 22 is pulled to drive the pull plate 18 and the plug plate 16 fixed to the pull rod 22 to overcome the elastic restoring force of the third elastic member and move until the positioning cylinder 19 reaches the positioning hole 26. In this process, under the action of the second elastic member 20, the positioning column 21 is away from the end of the second elastic member 20 and abuts against the limit plate 23. The positioning column 21 slides on the limit plate 23 as the pull rod 22 moves. When the positioning cylinder 19 reaches the positioning hole 26, the positioning column 21 is aligned with the positioning hole 26. Under the action of the second elastic member 20, the positioning The column 21 is inserted into the positioning hole 26 to fix the insert plate 16, and the passage between the oxygen absorption tube 30 and the connector body 1 or the atomizer tube 2 and the connector body 1 is opened. When it is necessary to close the passage between the oxygen absorption tube 30 and the connector body 1 or the atomizer tube 2 and the connector body 1, the reset pin 25 in the cartridge 24 on the limit plate 23 is pressed, and the end of the reset pin 25 close to the positioning hole 26 passes through the positioning hole 26, pushing the positioning column 21 into the positioning hole 26. At this time, the insert plate 16 is no longer fixed. Under the elastic restoring force of the third elastic member, the insert plate 16 is retracted to block the hole in the connecting ring 15, so that the passage between the oxygen absorption tube 30 and the connector body 1 or the atomizer tube 2 and the connector body 1 is in a closed state.

[0038] The above is only a preferred embodiment of the present invention. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present invention. These should also be regarded as the scope of protection of the present invention. These will not affect the effect of the implementation of the present invention and the practicality of the patent.
