Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical devices, in particular to an auxiliary device for assisting rescuers in mouth-to-mouth artificial respiration in on-site first aid. BACKGROUND

[0002] Mouth-to-mouth artificial respiration is the simplest and most effective method among all artificial respiration methods, and is most suitable for application in on-site first aid. It is often used in cardiopulmonary resuscitation (CPR) and respiratory arrest or difficulty due to various reasons (such as cardiac arrest, anesthesia, electric shock, poisoning, etc.), and timely and effective mouth-to-mouth artificial respiration can help patients obtain basic respiratory activity, avoid brain damage or death caused by hypoxia, and thus maintain basic life activities.

[0003] Although the effectiveness of mouth-to-mouth artificial respiration has been widely recognized in first aid practice, this method also has the following disadvantages:

[0004] 1. May cause infectious diseases: Since mouth-to-mouth artificial respiration involves direct oral contact, if the rescuer does not take appropriate protective measures, there is a risk of infection of infectious diseases such as influenza, hepatitis B, AIDS, etc. through respiratory tract transmission or body fluid transmission. This risk has become an obstacle for many people to implement CPR (cardiopulmonary resuscitation) in clinical practice.

[0005] 2. Operation skill is not easy to master: If the rescuer is not strictly trained, mouth-to-mouth artificial respiration often fails due to the following reasons: (1) the rescuer and the patient's oral cavity do not fit tightly, causing air leakage; (2) due to nervousness or lack of technical proficiency, etc. without pinching the nose, gas leaks from the nasal cavity; (3) insufficient airway opening leads to difficulty in blowing, etc. and operation failure will greatly affect the efficiency of CPR.

[0006] 3. Affecting chest compression time / cardiopulmonary resuscitation time (CCF value): In the process of cardiopulmonary resuscitation, chest compression is a key step to maintain blood circulation. If the rescuer spends too much time in mouth-to-mouth artificial respiration, the CCF value will be reduced, thereby affecting the blood supply to the brain and the whole body, and reducing the effect of first aid.

[0007] 4. Difficulty in implementation and psychological barriers: Mouth-to-mouth artificial respiration may pose certain psychological barriers to the rescuer, especially when faced with free objects or odors in the patient's mouth, which may cause nausea or discomfort. This psychological barrier may hinder the rescuer from timely and effectively implementing cardiopulmonary resuscitation.

[0008] In order to solve the above problems, some experts and scholars have invented artificial respiration auxiliary devices such as breathing masks, but due to the high cost, difficulty in carrying, and difficulty in reducing the difficulty of artificial respiration, they have not been popularized in practice, and more remain in the stage of first aid training or theory.

[0009] In addition, the Chinese utility model patent CN201120449668.6 discloses an artificial respiration auxiliary device for respiratory medicine, which comprises a blowing pipe, a blowing cover connected to the top of the blowing pipe, and an air inlet cover connected to the lower part of the blowing pipe. A one-way valve is arranged in the middle of the blowing pipe, a sleeve is arranged around the blowing pipe on the inner side of the air inlet cover, and the blowing cover and the air inlet cover are in the shape of a horn. In use, the rescuer sticks the air inlet cover to the patient's mouth and inserts the sleeve into the patient's mouth, then pinches the patient's nose with one hand and holds the blowing pipe with the other hand to blow air from the blowing cover. The one-way valve in the blowing pipe only allows the rescuer to blow air into the patient, and the patient's nose is released when the rescuer breathes.

[0010] Although the artificial respiration auxiliary device disclosed in the above patent document has a simple structure and can avoid cross infection, it still has the following defects in application: 1. The horn cover pressed on the patient's face is easy to cause poor sealing and air leakage, which can lead to insufficient ventilation; 2. After releasing the patient's nose, the patient will exhale from the nose and the mouth, and the air exhaled from the mouth may be trapped in the air inlet cover, which can prevent new oxygen from entering the patient's lungs and affect the efficiency of the next inhalation.

[0011] Therefore, the conventional artificial respiration auxiliary device still has certain use defects in actual application, and in order to greatly improve the success rate of rescue of diseases such as cardiac arrest, it is necessary to develop a device that can not only eliminate the risk of infectious diseases, but also reduce the difficulty of mouth-to-mouth artificial respiration, while ensuring the use effect and being low in cost. Content of the utility model

[0012] The present application provides a mouth-to-mouth artificial respiration auxiliary device to solve the problem of poor use effect of current artificial respiration auxiliary devices.

[0013] In order to achieve the above purpose, the present application provides the following technical solutions:

[0014] The present application provides a mouth-to-mouth artificial respiration auxiliary device, which comprises a jaw and face gel patch and a nose gel patch, a ventilation tube is installed on the jaw and face gel patch, one end of the ventilation tube penetrates through the jaw and face gel patch to form a patient breathing end, the other end of the ventilation tube forms a rescuer blowing end, a one-way valve is arranged in the ventilation tube, the one-way valve is used to guide the gas blown from the rescuer blowing end to the patient breathing end and prevent the gas from flowing back, and one or more exhaust holes are formed in the side wall of the ventilation tube, the gas entering the ventilation tube from the patient breathing end can be discharged from the exhaust hole.

[0015] In one embodiment of the present application, the one-way valve is a duckbill valve, which comprises two oppositely arranged diaphragms, one end of each diaphragm is a semicircular arc arranged along the inner wall of the ventilation tube, and the other end is a straight line matched with the inner diameter of the ventilation tube, the semicircular arc end of each diaphragm is fixedly connected with the inner wall of the ventilation tube, and the straight line end of each diaphragm abuts against each other and faces the patient breathing end, and the exhaust hole can be sealed by the two diaphragms in the open state.

[0016] In another embodiment of the present application, the one-way valve comprises a diaphragm arranged radially along the ventilation tube, a filter screen and a cross-shaped fixing frame are arranged on the side of the diaphragm close to the rescuer blowing end, a diaphragm opening limiting frame is arranged on the side of the diaphragm close to the patient breathing end, the diaphragm opening limiting frame is a grid plate arranged radially in the ventilation tube, one side of the grid plate forms a half-moon shaped notch, the exhaust hole is arranged between the grid plate and the diaphragm, and the exhaust hole is arranged in a staggered manner with the half-moon shaped notch; when gas enters the one-way valve from the rescuer blowing end, the gas pressure pushes the diaphragm to deflect axially along the ventilation tube and abut against the half-moon shaped notch of the grid plate, and the diaphragm forms a shielding seal to the exhaust hole, and the gas enters the patient airway; the diaphragm can prevent the patient exhaled gas from entering the rescuer blowing end, and the exhaust hole can exhaust the patient exhaled gas out of the ventilation tube.

[0017] Further in the above technical solution, the maxillofacial gel patch and the nasal gel patch are integrally connected.

[0018] Further, the shape of the maxillofacial gel patch is rectangular or elliptical, and the shape of the nasal gel patch is triangular.

[0019] Further, the ventilation tube is a cylindrical tube.

[0020] Further, the ventilation tube is a transparent plastic tube.

[0021] Further, the semicircular arc ends of the two diaphragms jointly form a circular gas inlet port of the duckbill valve, and the straight line ends of the two diaphragms form a gas outlet port of the duckbill valve, and the gas blown into the duckbill valve from the rescuer blowing end can make the straight line ends of the two diaphragms separate from each other and seal the exhaust hole on the ventilation tube.

[0022] Further, the duckbill valve is a silicone duckbill valve, a rubber duckbill valve, a polyurethane duckbill valve, or a thermoplastic elastomer duckbill valve.

[0023] Compared with the prior art, the present application has at least the following beneficial effects:

[0024] 1. The mouth-to-mouth artificial respiration auxiliary device provided by the application fixes the ventilation tube in the patient's mouth through the maxillofacial gel patch, and temporarily seals the patient's nose through the nasal gel patch to prevent the blown gas from being discharged from the patient's nose. In addition, the gel patch has certain softness, elasticity and adhesion, can be reliably attached to the patient's skin, prevents air leakage, and ensures the air intake efficiency. At the same time, the application avoids direct oral contact through the ventilation tube and eliminates the risk of infectious diseases. In addition, the application provides an exhaust hole on the ventilation tube, and when the rescuer blows, the one-way valve opens to not only ensure smooth ventilation but also prevent gas reflux. When the rescuer stops blowing, the one-way valve returns to the closed state, the exhaled gas from the patient's mouth enters the ventilation tube and is discharged from the exhaust hole. The design of the exhaust hole can prevent the exhaled gas from being retained in the ventilation tube, ensure that new oxygen can fully enter the patient's lungs, and ensure the next inhalation efficiency. Therefore, the mouth-to-mouth artificial respiration auxiliary device provided by the application not only has a simple structure, low manufacturing cost and is easy to carry, but also can eliminate the risk of infectious diseases and reduce the operation difficulty of mouth-to-mouth artificial respiration. In addition, it can also ensure the ventilation efficiency and use effect.

[0025] 2. The one-way valve in the application can be a duckbill valve. When the duckbill valve opens, it not only ensures smooth ventilation but also covers and seals the exhaust hole to prevent air leakage. When the rescuer stops blowing, the duckbill valve returns to the closed state to prevent gas reflux. The exhaled gas from the patient's mouth enters the ventilation tube and is discharged from the exhaust hole. The design of the exhaust hole can prevent the exhaled gas from being retained in the ventilation tube, ensure that new oxygen can fully enter the patient's lungs, and ensure the next inhalation efficiency.

[0026] 3. The one-way valve in the application can be a CPR breathing mask one-way valve on the market. During use, when gas enters the one-way valve from the rescuer's blowing end, the gas pressure pushes the diaphragm of the one-way valve to deflect axially along the ventilation tube and open against the crescent-shaped notch of the grid plate, and the diaphragm forms a shielding and sealing of the exhaust hole. The gas enters the patient's airway. When the patient exhales and the diaphragm is blown to reset, the diaphragm prevents the patient's exhaled gas from entering the rescuer's blowing end, and the patient's exhaled gas is discharged from the ventilation tube through the exhaust hole. Therefore, the application ensures smooth ventilation and prevents gas reflux through the one-way valve, and avoids the retention of exhaled gas in the ventilation tube through the exhaust hole, ensuring that new oxygen can fully enter the patient's lungs and ensuring the next inhalation efficiency.

[0027] 4. The mouth-to-mouth artificial respiration auxiliary device provided by the application prevents the rescuer from directly inhaling the patient's exhaled gas through the exhaust hole and duckbill valve, thereby eliminating the risk of infectious disease transmission caused by mouth-to-mouth artificial respiration.

[0028] 5. The mouth-to-mouth artificial respiration auxiliary device provided by the application only needs to be simply pasted with the gel patch and correctly open the airway to smoothly complete the mouth-to-mouth artificial respiration, thereby reducing the operation difficulty.

[0029] 6、The simplicity of operation and high success rate reduces the proportion of mouth-to-mouth artificial respiration in cardiopulmonary resuscitation, greatly improves the CCF value, and thus improves the success rate of cardiopulmonary resuscitation.

[0030] 7、The mouth-to-mouth artificial respiration auxiliary device provided by the application solves the psychological barriers and discomfort of rescuers to direct mouth-to-mouth artificial respiration, and increases the possibility of on-site rescue for patients with sudden cardiac arrest and other emergencies.

[0031] 8、The mouth-to-mouth artificial respiration auxiliary device provided by the application has simple structure, small size, is convenient to carry, and has low manufacturing cost and is easy to popularize. BRIEF DESCRIPTION OF DRAWINGS

[0045] The present application provides an oral artificial respiration auxiliary device. The application of the device can avoid direct contact with the oral mucosa, and at the same time prevent the rescuer from directly inhaling the exhaled gas of the patient, thereby eliminating the risk of transmission of infectious diseases due to oral artificial respiration. In addition, the device is simple to operate and use. When using, the rescuer only needs to simply paste the device and open the airway correctly, so as to successfully complete the oral artificial respiration, reduce the difficulty of oral artificial respiration operation, and solve the problem of air leakage from the mouth and nose when the rescuer blows. The structure and use method of the oral artificial respiration auxiliary device provided by the present application will be described below in combination with the drawings and specific embodiments.

[0046] Embodiment one

[0047] Referring to Figure 1 The oral artificial respiration auxiliary device provided by the present application mainly comprises a maxillofacial gel patch 1, a nasal gel patch 2 and a ventilation tube 3. The ventilation tube 3 is equivalent to a breathing valve, which can realize the ventilation rescue of the rescuer to the patient without direct contact between the rescuer and the patient's oral cavity. The ventilation tube 3 is embedded on the maxillofacial gel patch 1, and one end of the ventilation tube 3 penetrating the maxillofacial gel patch 1 forms a patient breathing end 31, and the other end of the ventilation tube 3 forms a rescuer blowing end 32.

[0048] In order to prevent the rescuer from directly inhaling the exhaled gas of the patient, the ventilation tube 3 is provided with a one-way valve for guiding the gas blown from the rescuer blowing end 32 to the patient breathing end 31 and preventing the gas from flowing back. One or more exhaust holes 33 are formed in the side wall of the ventilation tube 3, and the gas entering the ventilation tube 3 from the patient breathing end 31 can be discharged from the exhaust holes 33. The present application realizes smooth ventilation and prevents gas backflow through the one-way valve, and prevents the retention of exhaled gas in the ventilation tube through the exhaust holes.

[0049] In the present embodiment, the one-way valve described above is a duckbill valve, such as Figures 2 to 4 The duckbill valve 4 includes two oppositely arranged diaphragms 41, one end of each diaphragm 41 being a semicircular arc arranged radially along the inner wall of the ventilation tube 3, and the other end being a straight line matching the inner diameter of the ventilation tube 3. The semicircular arc-shaped ends of the two diaphragms 41 are fixedly connected to the inner wall of the ventilation tube 3, and the straight line-shaped ends of the two diaphragms 41 abut against each other and face the patient breathing end 31. One or more exhaust holes 33 are formed in the side wall of the ventilation tube 3, and the exhaust holes 33 can be sealed by the two diaphragms 41 in the open state.

[0050] In the present application, the number, size, and shape of the exhaust holes 33 can be arbitrary, as long as they can smoothly discharge gas to meet the actual use requirements. For example, two long strip-shaped exhaust holes 33 can be formed in the side wall of the ventilation tube 3, and the size of each exhaust hole 33 can be determined according to the degree of obstruction of the ventilation hole side wall by the duckbill valve 4 in the open state.

[0051] The duckbill valve 4 described above can realize one-way gas conduction and prevent gas backflow. Under normal circumstances, the duckbill valve 4 is in a normally closed state. When in use, the duckbill valve 4 can be opened by blowing gas into it through the rescuer blowing end 32, ensuring that the gas is smoothly introduced into the patient end. During the blowing interval or when the patient has spontaneous breathing, the gas discharged by the patient can be discharged from the exhaust holes 33, i.e., the duckbill valve 4 effectively isolates the paths of the rescuer blowing and the patient gas discharge.

[0052] In a preferred embodiment of the present application, the maxillofacial gel patch 1 and the nasal gel patch 2 are integrally connected, the maxillofacial gel patch 1 is used to attach to the patient's mouth and maxillofacial part, and the patient breathing end 31 of the ventilation tube 3 extending out of the maxillofacial gel patch 1 is inserted into the patient's mouth; the nasal gel patch 2 is used to attach to the patient's nose to prevent gas leakage from the patient's nose during artificial respiration, thereby affecting the rescue effect. The present application chooses to use a gel patch to seal the patient's mouth and nose because it has a certain softness, elasticity, and adhesion, can reliably attach to the patient's skin, prevent gas leakage, and ensure the gas intake efficiency.

[0053] It should be noted that the maxillofacial gel patch 1 and the nasal gel patch 2 are always attached to the patient's face during the artificial respiration assistance process. During the blowing interval or when the patient has spontaneous breathing, the patient directly exhales through the mouth and the exhaust hole 33 on the ventilation tube 3.

[0054] In other embodiments, the maxillofacial gel patch 1 and the nasal gel patch 2 described above can also be made in a split type.

[0055] In a preferred embodiment of the present application, the shape of the maxillofacial gel patch 1 described above can be rectangular, oval, racetrack-shaped or other shapes that can fit the human face. The maxillofacial gel patch 1 can be planar or curved. Similarly, the shape of the nasal gel patch 2 described above is preferably triangular, but can also be rectangular, oval or other shapes. The nasal gel patch 2 can be planar or curved.

[0056] In a preferred embodiment of the present application, the ventilation tube 3 is a cylindrical tube, which has a higher degree of fit with the shape of the human oral cavity than a square tube, and is convenient for blowing. Of course, the ventilation tube 3 can also be an elliptical columnar tube.

[0057] In a preferred embodiment of the present application, the ventilation tube 3 is a transparent plastic tube with a certain degree of hardness, which facilitates the observation of the opening and closing state of the duckbill valve 4 inside.

[0058] In a preferred embodiment of the present application, the semicircular arc-shaped end portions of the two diaphragms 41 of the duckbill valve 4 together form a circular air inlet port of the duckbill valve 4, and the linear end portions of the two diaphragms 41 form an air outlet port of the duckbill valve 4. The material of the duckbill valve 4 can be selected from silicone, rubber, polyurethane (PU) or thermoplastic elastomer (TPE).

[0059] The use method of the mouth-to-mouth artificial respiration assistance device provided by the present application is as follows: first, insert the patient breathing end 31 of the ventilation tube 3 into the patient's mouth, second, attach the maxillofacial gel patch 1 to the patient's face and attach the nasal gel patch 2 to the patient's nose, third, the rescuer blows air through the rescuer blowing end 32 of the ventilation tube 3, the gas blown into the duckbill valve 4 causes the linear end portions of the two diaphragms 41 to separate from each other and press and seal the exhaust hole 33 on the ventilation tube 3, and the gas smoothly enters the patient's lungs. During the blowing interval or when the patient has spontaneous breathing, the patient is in a passive state of receiving gas due to the large pressure of the gas blown by the rescuer, the duckbill valve 4 is opened, and once the rescuer stops blowing, the duckbill valve 4 is automatically closed. At this time, the gas exhaled by the patient with spontaneous breathing is discharged from the exhaust hole 33 on the ventilation tube 3. Therefore, the device effectively isolates the paths of the gas blown by the rescuer and the gas exhaled by the patient, avoiding the risk of transmission of infectious diseases.

[0060] Embodiment two

[0061] The embodiment provides a mouth-to-mouth artificial respiration auxiliary device, which is different from the embodiment one in that a one-way valve in the embodiment is a CPR breathing mask one-way valve with low price on the market, which is arranged between the patient breathing end and the rescuer blowing end of the ventilation tube. The structure of the one-way valve mainly comprises a diaphragm arranged in the radial direction of the ventilation tube, a filter screen and a cross-shaped fixing frame arranged on one side of the diaphragm close to the rescuer blowing end, and a diaphragm opening limiting frame arranged on one side of the diaphragm close to the patient breathing end 31. The diaphragm opening limiting frame is a grid plate arranged in the radial direction of the ventilation tube 3, one side of the grid plate is formed with a half-moon-shaped notch, and an exhaust hole 33 is arranged between the grid plate and the diaphragm. The exhaust hole is arranged in a staggered manner with the half-moon-shaped notch. When the gas enters the one-way valve from the rescuer blowing end 32, the gas pressure pushes the diaphragm to deflect in the axial direction of the ventilation tube 3 to open and abut against the half-moon-shaped notch of the grid plate, and the diaphragm forms a shielding seal to the exhaust hole 33, so that the gas enters the patient airway. After the patient has spontaneous breathing, the exhaled gas enters the ventilation tube 3 to push the diaphragm to reset, the diaphragm prevents the patient exhaled gas from flowing to the rescuer end, and the patient exhaled gas is discharged from the ventilation tube 3 through the exhaust hole 33, so as to prevent the gas from staying in the ventilation tube 3 and ensure the patient breathing.

[0062] In summary, the mouth-to-mouth artificial respiration auxiliary device provided by the application can avoid the direct contact of the oral mucosa of the rescuer and the patient, and at the same time, prevent the rescuer from directly inhaling the patient exhaled gas, thereby eliminating the risk of transmission of infectious diseases caused by mouth-to-mouth artificial respiration. In addition, the device reduces the difficulty of mouth-to-mouth artificial respiration operation, and the rescuer only needs to simply paste the device and correctly open the airway to successfully complete the mouth-to-mouth artificial respiration. Furthermore, the simplicity of operation and high success rate reduce the time proportion of mouth-to-mouth artificial respiration in cardiopulmonary resuscitation, greatly improve the CCF value, and thereby improve the success rate of cardiopulmonary resuscitation. In addition, the application also solves the psychological barriers and discomfort of the rescuer to direct mouth-to-mouth artificial respiration, and increases the possibility of on-site rescue for patients with sudden cardiac arrest and other emergencies. At the same time, the device has a simple structure, small size, easy portability, and extremely low cost and is easy to popularize.

[0063] Any combination of the technical features of the above embodiments can be made (as long as the combination of the technical features does not exist contradictory), in order to make the description simple, not all possible combinations of the technical features in the above embodiments are described; these embodiments which are not explicitly written should also be considered as the scope of the present application.

[0064] The application is described in detail above by general description and specific embodiments. It should be understood that based on the technical concept of the application, some conventional adjustments or further innovations can be made to the specific embodiments; as long as the technical concept of the application is not deviated, the technical solutions obtained by the conventional adjustments or further innovations also fall within the protection scope of the claims of the application.
