Description

Technical Field

[0001] The present application relates to the field of medical devices, and in particular to an auxiliary sound valve. Background Art

[0002] Tracheotomy tube is a common medical device for respiratory anesthesia. It is widely used in clinical practice to rescue critically ill patients, establish a respiratory management system, and keep the patient's airway open. Its simple operation method and significant use effect have been well received by clinicians and patients. For patients who need to be inserted with a tracheotomy tube, the trachea in the larynx needs to be cut open, and then the tracheal tube is inserted. For patients with autonomous consciousness, the machine end of the tracheotomy tube is equipped with an auxiliary voice valve to enable the patient to speak.

[0003] Since the air enters the trachea directly through the auxiliary generator valve, on the one hand, the air temperature is much lower than the patient's body temperature, which will irritate the patient's respiratory tract and affect the patient's usage experience and physical recovery; on the other hand, the air humidity is also lower than the patient's body humidity, and the gas inhaled into the trachea is too dry, which is not conducive to the patient's physical health.

[0004] Therefore, there is an urgent need for an auxiliary sounding valve that can achieve temperature and humidity transition. Utility Model Content

[0005] The purpose of the present application is to provide an auxiliary sounding valve that can achieve temperature and humidity transition.

[0006] The embodiments of the present application can be implemented through the following technical solutions:

[0007] An auxiliary sounding valve can be connected to a tracheotomy tube and an oxygen tube, comprising an upper cover, a temperature and humidity transition part, a support frame and a main frame. The main frame and the upper cover surround a cavity to accommodate the temperature and humidity transition part and the support frame. The support frame is located at the bottom of the main frame and is arranged opposite to the upper cover. The top of the support frame abuts against the temperature and humidity transition part. The inner side of the main frame can abut against the inner and outer sides of the temperature and humidity transition part at the same time. The upper cover, the temperature and humidity transition part, the main frame and the oxygen port can form an air circulation channel with the tracheotomy tube and the oxygen tube.

[0008] Furthermore, the support frame includes a support body, the support body is an annular structure, and the outer diameter of the support body is smaller than the inner diameter of the main frame.

[0009] Preferably, the support frame further comprises a first protrusion and a second protrusion, wherein the first protrusion and the second protrusion are arranged on a side of the support body facing away from the upper cover, and can abut against the bottom of the main frame at the same time;

[0010] The first protrusion corresponds to the outer ring position of the support body, the second protrusion corresponds to the inner ring position of the support body, and the arc length of the first protrusion is smaller than the arc length of the second protrusion.

[0011] Furthermore, the temperature and humidity transition portion is an annular structure and is made of sponge material.

[0012] Furthermore, the upper cover includes a cover body, a ventilation port and a connecting portion, the ventilation port is a through hole located on the cover body, and the upper cover is detachably connectable to the main frame via the connecting portion.

[0013] Further, the main frame includes an outer shell, a cannula connection port, a first matching portion, an oxygen port and a ventilation side hole, the bottom surface of the outer shell is closed, the cannula connection port is a cylindrical structure connected to the bottom of the outer shell, the first matching portion is connected to the outer side of the cannula connection port and is detachably connectable to the connection portion, the ventilation side hole is a through hole located on the peripheral side of the outer shell, the oxygen port is connected to the bottom of the outer shell, the outer side of the oxygen port is connected to the oxygen tube, and the inner side is connected to the inner cavity of the outer shell;

[0014] The temperature and humidity transition part and the support frame are sleeved on the outer periphery of the cannula connection port, and the cannula connection port (42) can be connected to the tracheotomy cannula.

[0015] Furthermore, the connecting portion is snap-connected with the first matching portion.

[0016] Preferably, the housing comprises a second matching portion, which is opened on a side wall of the housing and can accommodate the oxygen port.

[0017] Further, the supporting body comprises an arched protrusion matching the shape of the second matching portion, and the bottom of the arched protrusion can abut against the top of the second matching portion.

[0018] The auxiliary sounding valve provided by the embodiment of the present application has at least the following beneficial effects:

[0019] (1) The present application achieves the transition of temperature and humidity by providing a temperature and humidity transition part between the main frame and the upper cover. During exhalation, the gas is exhaled from the intubation connection port, and the temperature and humidity transition part can retain part of the water and heat in the exhaled air through the ventilation port and the ventilation side hole. During inhalation, when an oxygen tube is inserted into the oxygen port, the inhaled gas passes through the oxygen port and is surrounded by the supporting body and is dissipated to the temperature and humidity transition part, and enters the airway through the intubation connection port; when the oxygen tube is not connected, the inhaled gas passes through the ventilation side hole to the temperature and humidity transition part, and then enters the airway through the intubation connection port. Both methods can bring part of the water and heat retained in the temperature and humidity transition part back into the body during inhalation, thereby ensuring the transition of temperature and humidity and providing the patient with air of appropriate temperature and humidity;

[0020] (2) The support frame in the present application is provided with a first protrusion and a second protrusion, and the arc length of the first protrusion is smaller than the arc length of the second protrusion, so that the outer ring corresponding to the first protrusion is in a suspended state, ensuring that the gas flowing from the main frame can evenly contact and dissipate with the temperature and humidity transition part, thereby ensuring the uniform dissipation of the gas;

[0021] (3) The present application presses the ventilation port so that no gas is emitted from the ventilation port, so that the gas exhaled by the patient can drive the vocal cords through the airway to produce sound, thereby achieving the effect of assisting phonation.

DETAILED DESCRIPTION

[0028] Hereinafter, the present application will be further described based on preferred embodiments with reference to the accompanying drawings.

[0029] The vocabulary in this specification is used to illustrate the embodiments of the present application, but is not intended to limit the present application. Unless otherwise clearly specified and limited, the terms "disposed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, or it can be detachably connected, or connected in one piece; it can be a mechanical connection, it can be directly connected, it can be indirectly connected through an intermediate medium, and it can be the internal communication of two elements. For those skilled in the art, the specific meanings of the above terms in this application can be specifically understood.

[0030] In addition, in the description of the embodiments of the present application, various components on the drawings are enlarged or reduced in size for ease of understanding, but this practice is not intended to limit the scope of protection of the present application.

[0031] Figure 1 and Figure 2 They are respectively the overall structure diagram and the exploded diagram of the auxiliary sound valve in this application, such as Figure 1 and Figure 2 As shown, the auxiliary sounding valve can be connected to the tracheotomy cannula and the oxygen tube to assist the patient in making sounds while ensuring breathing. The auxiliary sounding valve includes an upper cover 1, a temperature and humidity transition part 2, a support frame 3 and a main frame 4. The main frame 4 and the upper cover 1 surround a cavity to accommodate the temperature and humidity transition part 2 and the support frame 3. The support frame 3 is located at the bottom of the main frame 4 and is arranged opposite to the upper cover 1. The top of the support frame 3 abuts against the temperature and humidity transition part 2. The inner side of the main frame 4 can abut against the inner and outer sides of the temperature and humidity transition part 2 at the same time. The upper cover 1, the temperature and humidity transition part 2, the main frame 4, and the oxygen port 44 can form an air circulation channel with the tracheotomy cannula and the oxygen tube. When exhaling, the gas is exhaled from the cannula connection port. Through the ventilation port and the ventilation side hole, the temperature and humidity transition part can retain part of the water and heat in the exhaled air. During inhalation, when an oxygen tube is inserted into the oxygen port, the inhaled gas passes through the oxygen port and is surrounded by the supporting body and is dissipated to the temperature and humidity transition part, and enters the airway through the intubation connection port; when the oxygen tube is not connected, the inhaled gas passes through the ventilation side hole to the temperature and humidity transition part, and then enters the airway through the intubation connection port. Both methods can bring part of the water and heat retained in the temperature and humidity transition part back to the body during inhalation, thereby ensuring the transition of temperature and humidity and providing the patient with air with suitable temperature and humidity.

[0032] like Figure 3 and Figure 4 As shown, the support frame 3 includes a support body 31, which is a ring-shaped structure. The outer diameter of the support body 31 is smaller than the inner diameter of the main frame 4. A cavity for accommodating the temperature and humidity transition part 2 is formed between the support body 31 and the main frame 4 to achieve a stable connection of the temperature and humidity transition part 2.

[0033] In some preferred embodiments of the present application, Figure 4 As shown, the support frame 3 also includes a first protrusion 32 and a second protrusion 33 which are arranged on the side of the support body 31 facing away from the upper cover 1, and can abut against the bottom of the main frame 4 at the same time, which can not only provide sufficient supporting force for the support body 31, but also ensure that the gas is evenly dispersed from the temperature and humidity transition part 2, rather than dispersing air from only one place of the temperature and humidity transition part 2.

[0034] Furthermore, the first raised portion 32 corresponds to the outer ring position of the support body 31, the second raised portion 33 corresponds to the inner ring position of the support body 31, and the arc length of the first raised portion 32 is smaller than the arc length of the second raised portion 33, so that part of the outer ring corresponding to the first raised portion 32 is in a suspended state, ensuring that the gas flowing from the main frame 4 can evenly contact and dissipate with the temperature and humidity transition portion 2, thereby ensuring uniform dissipation of the gas.

[0035] In some specific embodiments of the present application, Figure 2 As shown, the temperature and humidity transition part 2 is an annular structure and is made of sponge material, which has the advantages of easy processing, simple installation and low cost.

[0036] like Figure 1 , Figure 2 As shown, the upper cover 1 includes a cover body 11 , a vent port 12 and a connecting portion 13 . The vent port 12 is a through hole located on the cover body 11 , providing a passage for the circulation of gas. The upper cover 1 is detachably connectable to the main frame 4 through the connecting portion 13 .

[0037] Furthermore, if Figure 5 As shown, the main frame 4 includes an outer shell 41, a cannula connection port 42, a first matching portion 43, an oxygen port 44 and a ventilation side hole 45, wherein the outer shell 41 is closed at the bottom and open at the top, and the top surface can be matched with the upper cover 1; the cannula connection port 42 is a cylindrical structure connected to the bottom of the outer shell 41, the first matching portion 43 is connected to the outer side of the cannula connection port 42 and is detachably connectable to the connecting portion 13, the support frame 3 and the temperature and humidity transition portion 2 are sleeved on the outer periphery of the cannula connection port 42, and the cannula connection port 42 can be connected to the tracheotomy cannula; the ventilation side hole 45 is a through hole located on the peripheral side of the outer shell 41, and the ventilation side hole 45 can form another passage for air circulation; the oxygen port 44 is connected to the bottom of the outer shell 41, which can be connected to the oxygen tube, and the inner side is connected to the inner cavity of the outer shell 41, providing a passage for air circulation.

[0038] In some specific embodiments of the present application, the number of the ventilation side holes 45 is 4, which can ensure air circulation without leaking too much air when the oxygen inhalation tube is inserted.

[0039] In some preferred embodiments of the present application, the connecting portion 13 is snap-connected with the first matching portion 43 , which can facilitate disassembly while ensuring the stability of the connection.

[0040] In some preferred embodiments of the present application, Figure 2 and Figure 5 As shown, the housing 41 includes a second matching portion 411, and the second matching portion (411) is opened on the side wall of the housing (41), providing a receiving space for the oxygen port 44, thereby reducing the volume of the auxiliary sounding valve.

[0041] Furthermore, the support body 31 includes an arched protrusion 311 that matches the shape of the second matching portion 411 , and the bottom of the arched protrusion 311 can abut against the top of the second matching portion 411 to achieve shape fit of the support body 31 to provide good supporting force therefor.

[0042] In summary, the working principle of the auxiliary sound valve in the present application is: when worn normally, the gas is exhaled from the cannula connection port 42 during exhalation, and is dissipated through the temperature and humidity transition part 2, the ventilation port 12 and the ventilation side hole 45. The temperature and humidity transition part 2 can retain part of the water and heat in the exhaled air. During inhalation, on the one hand, the gas passes through the ventilation port 12 and the ventilation side hole 45, through the temperature and humidity transition part 2, and then enters the airway through the cannula connection port 42. On the other hand, the gas passes through the oxygen port and is surrounded by the support body 31 and is dissipated to the temperature and humidity transition part 2, and enters the airway through the cannula connection port 42. Inhalation can bring part of the water and heat retained in the temperature and humidity transition part 2 back to the body, thereby ensuring the transition of temperature and humidity, and providing the patient with air with suitable temperature and humidity. When the operator presses the ventilation port 12 with a finger, no gas is emitted from the ventilation port 12, so that the gas exhaled by the patient can drive the vocal cords through the airway to make a sound, thereby achieving the effect of assisting the sound; after the operator removes the finger, the upper cover 1 returns to its original position, and the inhalation and exhalation can continue. The temperature and humidity transition part 2 retains part of the water and heat in the exhaled air, and returns it to the respiratory tract during the inhalation process, and a better temperature and humidity exchange effect can be achieved after a few breaths.

[0043] The above is a detailed introduction to the specific implementation methods of the present application. For those skilled in the art, several improvements and modifications may be made to the present application without departing from the principles of the present application. These improvements and modifications also fall within the scope of protection of the claims of the present application.
