Description

Technical Field

[0001] The present invention relates to the field of speaking valves, and particularly to a multi-interface speaking valve. Background Art

[0002] In the medical field, tracheotomy is a common operation to relieve laryngeal dyspnea, respiratory dysfunction, or dyspnea caused by retention of lower respiratory tract secretions; after tracheotomy, patients generally need to use a speaking valve to help restore their vocalization and language abilities.

[0003] Existing speaking valves generally consist of a cylindrical housing and a valve. As a one-way ventilation valve, the speaking valve is connected at the tracheal cannula. During inhalation, the valve opens, and air flows through the gap opened by the valve into the airway. During exhalation, the valve closes, and air is exhaled from the gap between the tracheotomy cannula and the trachea through the upper respiratory tract. Existing speaking valves are generally designed in various types due to different usage scenarios. For example: standard type (integrated housing), oxygen interface type (oxygen interface tube is set on the side of the housing), etc. If oxygen inhalation is required during use, a standard block plus a tracheotomy mask can be selected, and the mask is connected to the oxygen tube; or a speaking valve with an oxygen interface can be selected for replacement.

[0004] However, both of the above two speaking valves have certain limitations in use; the first method requires the equipped with relevant accessories, and the process is relatively complex during use; the second method is mainly suitable for tracheotomy patients who require long-term oxygen therapy and have a vocalization need for long-term use; on the other hand, secretions such as sputum will be generated in the patient's trachea. If not removed in time, it may lead to the formation of sputum crusts and cause dangerous situations such as asphyxia. When performing sputum aspiration operations for the above two speaking valves, medical staff need to first remove the speaking valve and then connect the sputum aspiration device. The operation is relatively cumbersome, and during the process of removing the speaking valve, it may affect the patient's respiratory state and vocalization function, bringing discomfort and risks to the patient.

[0005] In summary, the standard block speaking valve and the oxygen interface type speaking valve in the prior art have limitations, and when performing sputum aspiration operations, the valve needs to be removed first and then the sputum aspiration device is connected, which may also affect the patient's breathing and vocalization functions. Summary of the Invention

Detailed implementation manners

[0030] The following will describe the detailed implementation manners of the present invention in detail, but it should be understood that the protection scope of the present invention is not limited by the detailed implementation manners.

[0031] As Figures 1 to 6 shown, a multi-interface speaking valve provided by an embodiment of the present invention includes a housing 1, and a connecting mechanism is arranged inside the housing 1. The connecting mechanism includes:

[0032] A connecting pipe 2, the connecting pipe 2 is detachably arranged inside the housing 1, and a through groove 3 is formed on the surface of the housing 1; a driving assembly is arranged between the housing 1 and the connecting pipe 2, the driving assembly is slidably connected to the connecting pipe 2, and the driving assembly is rotatably arranged inside the housing 1;

[0033] A driving ring 4, the driving ring 4 is rotatably arranged on the surface of the housing 1, the driving ring 4 covers the through groove 3, a connecting groove 5 and an insertion groove 6 are formed on the surface of the driving ring 4, the insertion groove 6 and the through groove 3 are in the same horizontal plane, and the connecting groove 5 is adapted to the end of the connecting pipe 2; the cross-section of the connecting groove 5 is in an L shape that is horizontally mirrored, a sealing rod 7 is slidably connected inside the driving ring 4, the edge of the sealing rod 7 is perpendicular to the edge of the connecting groove 5, and a moving assembly is arranged between the sealing rod 7 and the housing 1, and the moving assembly is fixedly arranged inside the housing 1;

[0034] A fixing assembly, the fixing assembly is slidably arranged between the driving ring 4 and the housing 1;

[0035] In summary, a multi-interface speaking valve provided by an embodiment of the present invention includes a connecting pipe 2 rotatably arranged inside a housing 1 and a through groove 3 opened on the surface of the housing 1. The breathing pipe can be connected through the connecting pipe 2, and the through groove 3 provides an insertion position for the sputum suction pipe. A driving ring 4 is rotatably arranged on the surface of the housing 1. An insertion groove 6 and a connecting groove 5 adapted to the end of the connecting pipe 2 are opened on the surface of the driving ring 4. Thus, the rotation of the driving ring 4 can selectively cause the connecting pipe 2 to rotate out of the driving ring 4 or the insertion groove 6 to communicate with the through groove 3. Thus, the surface of the housing 1 can be directly connected to the oxygen inhalation pipe, and there is a passage through which the sputum suction pipe can pass, and sputum can be directly aspirated through the sputum suction pipe, avoiding the cumbersome operation of removing the speaking valve before aspirating sputum. When sputum aspiration and connection of the breathing pipe are not required, the position of the driving ring 4 can be changed to limit the end of the connecting pipe 2 inside the housing 1, and the connecting groove 5 and the insertion groove 6 are disengaged, so that there is no protruding structure on the surface of the housing 1, realizing the most basic speaking valve function, with relatively wider functions and more convenient operation;

[0036] In some specific embodiments, the connecting pipe 2 includes a bent pipe, a silicone tube and an insertion column, which are connected in sequence. The insertion column is threadedly connected to the inside of the housing 1; the connecting pipe 2 is divided into three structures. The silicone tube is connected to the breathing pipe, the bent pipe enables the breathing pipe to fit with the surface of the housing 1, and the connecting pipe 2 can be disassembled through the insertion column, facilitating subsequent disinfection and cleaning;

[0037] In some specific embodiments, the driving component includes a rotating rod 8 rotatably arranged inside the housing 1. A driving groove 9 is opened on the surface of the rotating rod 8. The cross-section of the driving groove 9 is fan-shaped, and the driving groove 9 is adapted to the connecting pipe 2; through the driving groove 9 on the surface of the rotating rod 8, the structure of the connecting pipe 2 can be contacted. The fan-shaped connecting groove 5 enables the bent pipe to change its position when the rotating rod 8 rotates. Thus, by rotating the rotating rod 8, the position of the silicone tube can be changed;

[0038] In a further embodiment, a reset groove 10 is opened on the surface of the rotating rod 8. A reset rod is fixedly connected inside the housing 1. The center of the reset rod coincides with the center of the rotating rod 8. An annular spring 11 is fixedly connected between the reset rod and the reset groove 10; the annular spring 11 can provide a force for reset after rotation. Thus, when the driving ring 4 does not block the silicone tube, the silicone tube can rotate quickly, avoiding manual adjustment of the position, and the position of the connecting pipe 2 can be ensured to be maintained during use;

[0039] In some specific embodiments, the moving component includes a moving block 12 fixedly arranged inside the housing 1. The cross-section of the moving block 12 is triangular, and the hypotenuse of the moving block 12 contacts the sealing rod 7. A sealing spring 13 is fixedly connected between the sealing rod 7 and the driving ring 4. The triangular moving block 12 can push the sealing rod 7 to slide, causing one end of the connecting groove 5 to open. At the same time, there is a distance between the edge of the moving block 12 and the edge of the sealing cover, providing a rotation area for the connecting pipe 2.

[0040] In some specific embodiments, the fixing component includes a fixing rod 14 slidably arranged inside the driving ring 4. A fixing spring 15 is fixedly connected between the fixing rod 14 and the driving ring 4. A plurality of fixing grooves 16 are formed on the surface of the housing 1, and the fixing grooves 16 are adapted to the fixing rod 14. By the contact between the fixing rod 14 and the fixing grooves 16, the position of the driving ring 4 after rotation can be restricted. Thus, when using the connecting pipe 2 or the insertion groove 6, the driving ring 4 can be prevented from shifting.

[0041] In some specific embodiments, the driving ring 4 includes an operation ring and a flexible belt.

[0042] It should be noted that the flexible belt is made of a flexible metal material.

[0043] Both the through groove 3 and the connecting groove 5 are formed on the surface of the flexible belt. The fixing rod 14 is slidably arranged inside the operation ring. One end of the flexible belt is rotatably connected to one end of the operation ring. A knotting component is arranged between the flexible belt and the operation ring.

[0044] In a further embodiment, the knotting component includes a knotting rod 17 fixedly arranged at the other end of the flexible belt. A knotting groove 18 is formed at the other end of the operation ring. The knotting rod 17 is adapted to the knotting groove 18. Two magnetic pieces with opposite magnetic poles are arranged on the opposite sides of the knotting rod 17 and the knotting groove 18. Through the knotting component, the surface of the driving ring 4 can be made to fit the surface of the housing 1 and can be opened.

[0045] In a still further embodiment, a moving groove 20 is formed on the surface of the housing 1. A moving shaft 19 is fixedly connected to the surface of the operation ring. The moving shaft 19 is adapted to the moving groove 20. Through the moving groove 20 and the moving shaft 19, the operation ring can be disassembled, which is convenient for disassembly and cleaning.

[0046] The working principle of the present invention:

[0047] When assembling the combined connection mechanism, first slide the operation ring into the interior of the housing 1 corresponding to the positions of the moving groove 20 and the moving shaft 19. Then insert the knotting rod 17 at the end of the flexible belt into the knotting groove 18 to make the flexible belt fit the housing 1. Next, slide the operation ring to a suitable position, and the fixing rod 14 slides into the fixing groove 16 under the action of the fixing spring 15, fixing the positions of the housing 1 and the driving ring 4.

[0048] When the insertion slot 6 needs to be used, pull the fixing rod 14 to disengage the fixing rod 14 from the fixing groove 16, rotate the operation ring to align the insertion slot 6 with the through slot 3, and then release the fixing rod 14 to insert the fixing rod 14 into the fixing groove 16.

[0049] When the connecting pipe 2 needs to be used, pull the fixing rod 14 to disengage the fixing rod 14 from the fixing groove 16, rotate the operation ring. After the moving block 12 fits the sealing rod 7, rotate again to make the sealing rod 7 slide relative to the flexible belt, and the connecting pipe 2 rotates under the action of the annular spring 11.

[0050] The above discloses only several specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto, and any changes that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
