Description

Technical Field

[0001] This utility model belongs to the field of voice valve technology, and specifically relates to a voice valve. Background Technology

[0002] Currently, for patients unable to breathe independently, tracheotomy usually involves inserting an endotracheal tube to address breathing difficulties and abnormal respiratory function. However, after endotracheal intubation, the patient's airflow can only communicate with the outside world through the tube, not through the upper airway. Therefore, the patient cannot speak and may even experience impaired swallowing function. Existing methods to help patients speak include: 1. plugging the tracheostomy tube opening with a cork or gauze; 2. installing a special sound valve device. The disadvantage of plugging the tracheostomy tube opening is that it significantly increases the patient's inspiratory resistance, leading to insufficient inhalation and affecting the patient's health. Installing a sound valve solves this problem, but existing sound valve devices are limited, and existing sound valves offer only one method for adjusting expiratory ventilation, are not smooth to operate, and can easily affect product use during adjustment. The patient's experience during use still has room for improvement. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies in terms of inconvenient adjustment, and to propose a voice valve. This voice valve allows for stepless adjustment of the intake ventilation volume, enabling patients to switch between breathing and speaking needs. It reduces the frequency of disassembly of the voice valve and minimizes the impact of adjustment operations on component connections during use, making it more convenient to use.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] Design a voice valve including a base housing, an upper cover housing, a bracket, and a flexible valve housing. The base housing has an air duct connector on one side. The upper cover housing is snapped onto the base housing to form a valve housing. A breathing channel is formed through the axis of the valve housing. The valve housing is sleeved on the bracket to form a valve body. The valve body is disposed in the cavity formed between the base housing and the upper cover housing.

[0006] It also includes an adjustment ring, which is rotatably disposed on the outside of the upper cover housing.

[0031] The structural features of this utility model will now be described in detail with reference to the accompanying drawings.

[0032] Example 1

[0033] See Figures 1-6A voice valve includes a base housing 1, an upper cover housing 2, a bracket 4, and a flexible valve housing 3. One side of the base housing 1 has an air supply tube connector 11, which allows for oxygen supply via an air supply tube. Another side of the base housing 1 has a lanyard hole 14, which allows the product to be connected to a tracheal tube via a securing strap to prevent loss or confusion. The upper cover housing 2 is a short cover structure, allowing the user to directly obtain gas from the outside atmosphere during use. The upper cover housing 2 is attached to the base housing 1 by a snap-fit ​​mechanism to form the valve housing. The snap-fit ​​mechanism consists of a matching locking block 12 and a locking groove 22 on the side where the base housing 1 and the upper cover housing 2 meet. The locking groove 22 is a curved groove structure. During installation, the locking block 12 is engaged in the locking groove 22 by rotating the snap-fit ​​mechanism. To prevent the locking block 12 from easily detaching from the locking groove 22, a recessed locking groove 24 is provided on the inner side of the curved groove of the locking groove 22. A locking block 13 is provided on the protruding surface of the locking block 12, which is adapted to the locking groove 24. After the locking block 12 is engaged in the inner side of the locking groove 22, the locking block 13 can be locked in the locking groove 24, thus locking the locking block 12. A breathing channel is formed through the axis of the valve housing. The valve housing 3 is sleeved on the bracket 4 to form the valve body. The valve body is located in the cavity formed between the base housing 1 and the upper cover housing 2. The bottom of the valve housing 3 is symmetrically provided with a double-leaf split valve 31. To ensure the opening of the valve 31 is unaffected, a fixing seat 21 for fixing the valve body is provided inside the upper cover housing 2. The inner diameter of the fixing seat 21 is adapted to the outer diameter of the valve housing 3. The valve housing 3 is fixed in the fixing seat 21 by embedding, so that the bottom of the valve housing 3 is in a suspended state. To ensure a stable connection between the valve housing 3 and the bracket 4, a positioning groove 32 is provided on the inner side wall of the valve housing 3 along the height direction. A positioning slider 41 adapted to the positioning groove 32 is provided on the outer side of the bracket 4 along the height direction. A limiting block 33 is provided on the inner side of the top of the valve housing 3. A limiting groove 42 adapted to the limiting block 33 is provided on the top edge of the bracket 4. When the valve housing 3 is fitted onto the bracket 4, the positioning slider 41 is inserted into the positioning groove 32, and the limiting block 33 is engaged in the limiting groove 42, making the assembly between the valve housing 3 and the bracket 4 more convenient.

[0034] It also includes an adjusting ring 5, which is rotatably mounted on the outside of the upper cover housing 2. To facilitate the rotation of the adjusting ring 5, multiple outwardly protruding friction strips 52 are provided on the circumference of the adjusting ring 5. Long strip-shaped ventilation holes 23 are provided radially on both sides of the upper cover housing 2. Multiple adjusting holes 51 are provided radially on the adjusting ring 5 corresponding to the positions of the ventilation holes 23. The adjusting ring 5 has at least one adjusting indicator 53, and the upper cover housing 2 has a calibration point 25 corresponding to the position of the adjusting indicator 53. When the adjusting indicator 53 is aligned with the calibration point 25, the ventilation holes 23 and the adjusting holes 51 are offset from each other. At this time, the ventilation holes 23 are in a closed state. By rotating the adjusting ring 5 to the left or right through the friction strips 52, the flow rate of external gas entering the voice valve can be adjusted. When the adjusting holes 51 are aligned with the ventilation holes 23, the ventilation holes 23 are in a through state. The flow rate of the gas depends on the number of adjusting rings 5 ​​connected to the ventilation holes 23. The more adjusting rings 5 ​​connected, the greater the flow rate of the gas.

[0035] The voice valve of this invention is easy to operate. On the one hand, it lowers the barrier to entry for voice valves, making them suitable for more patients, and reduces the frequency of disassembly, making it more convenient to use. On the other hand, it allows for stepless adjustment of the intake and ventilation volume during use, enabling patients to switch between breathing and speaking needs. Without affecting disassembly, it reduces the impact of adjustment operations on component connections during use.

[0036] Specifically, during use, when the adjusting ring 5 is aligned with the upper cover housing 2, the ventilation hole 23 and the adjusting hole 51 are completely misaligned, preventing airflow. Under a certain pressure difference, the valve 31 can open to expose the airway. During the use of the voice valve, when the user exhales, the valve 31 is supported by the bracket 4, and the exhaled air cannot enter the outside through the airway but can only be exhaled through the trachea and vocal cords, allowing the user to speak. When the user inhales, the valve 31 is subjected to internal and external air pressure and moves away from the bracket 4. At this time, external air can enter the user's trachea through the air inlet on the upper cover housing 2, the airway on the bracket 4, and the open valve 31 to supply air to the user.

[0037] Example 2

By providing the connecting pipe 15, the upper cover shell 2 can be an elongated cover structure. In use, the voice valve can be connected to the ventilator through the air inlet tube, at which time the user can inhale the gas provided by the ventilator.

[0039] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
