Description

Technical Field

[0001] The utility model belongs to the technical field of medical ventilation devices, and in particular relates to a manual fast-inflated airway auxiliary ventilation device. Background Art

[0002] Airway ventilation is the most effective first aid measure when the patient has respiratory arrest. At this time, the patient's tongue ligament will be disabled, and the airway must be fully opened to complete normal ventilation, otherwise the air cannot enter the patient's lungs normally to complete the rescue of the patient.

[0003] The fastest first aid method in non-medical institutions is mouth-to-mouth artificial respiration. Surveys show that most normal people cannot accept mouth-to-mouth artificial respiration for cardiac arrest patients, and without training, most ordinary people cannot correctly complete the action of opening the airway.

[0004] Existing open airway assist devices such as endotracheal intubation, laryngeal mask airway, oropharyngeal airway, etc., are not able to be properly used by many ordinary medical personnel except for anesthesiologists, emergency department, ICU and other medical personnel with rescue skills in medical institutions. In emergency situations, it is easy to cause patients to be unable to ventilate normally, and due to prolonged hypoxia, patients may suffer from other problems such as hypoxic-ischemic encephalopathy.

[0005] Therefore, a manual rapid-inflation airway assist ventilation device is proposed. Utility Model Content

[0006] The utility model aims to provide a manual rapid inflation airway auxiliary ventilation device, which has a manual rapid inflation function and solves the problem that the prior art cannot correctly complete the airway opening action when rescuing a patient.

[0007] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is that the utility model provides a manual quick-inflation airway auxiliary ventilation device, including a mouth covering cloth, a mouth pad is arranged in the center of the mouth covering cloth, an air injection port is arranged through the middle of the mouth pad, an air injection tube is connected to the rear side of the air injection port, an inflation bag is arranged at the end of the air injection tube, the inflation bag is connected to the inflation tube, the bottom end of the inflation tube is connected to the inflation device, and a one-way valve is arranged on the inflation tube.

[0008] Preferably, the mouth covering cloth is made of medical non-woven fabric.

[0009] Preferably, one end of the inflation tube is connected to the inflation device and then passes through the mouth pad and is connected to the inflation bag at the other end.

[0010] Preferably, the inflatable device is an inflatable ball.

[0011] Preferably, the inflation device is an air injection cylinder.

[0012] Preferably, the front end of the gas injection pipe is made of hard material and the rear end is made of soft material.

[0013] Preferably, the mouth pad is in a circular shape with a soft filler disposed inside.

[0014] Compared with the prior art, the advantages and positive effects of the utility model are:

[0015] 1. The utility model can assist in respiratory ventilation. After the tube is placed, the air bag is inflated to support the opening of the patient's throat airway, making it convenient to supply air to the patient;

[0016] 2. The utility model has a manual rapid inflation function, which solves the problem that the prior art cannot correctly complete the airway opening action when rescuing patients. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] Embodiment 1, as Figure 1-2As shown, a manual fast-inflating airway assisted ventilation device includes a mouth cover 1. The mouth cover 1 is used to be placed on the patient's lips to avoid direct contact with the patient during first aid and improve hygiene. A mouth pad 2 is arranged at the center of the mouth covering cloth 1, and the mouth pad 2 is used to fix and protect the patient's mouth. An air injection port 3 is arranged through the middle of the mouth pad 2, and air is injected into the patient's mouth through the air injection port 3. An air injection tube 4 is connected to the rear side of the air injection port 3, and the air injection tube 4 is inserted into the patient's mouth to supply air to the patient's respiratory tract. An inflatable bag 5 is arranged at the end of the air injection tube 4. After the inflatable bag 5 is filled with gas, it expands and supports the patient's throat airway to ensure the openness of the airway and facilitate ventilation. An inflatable tube 6 is connected to the inflatable bag 5, and the bottom end of the inflatable tube 6 is connected to an inflatable device. The gas provided by the inflatable device flows into the inflatable bag 5 through the inflatable tube 6, so that the inflatable bag 5 is filled and supports the airway. A one-way valve 7 is arranged on the inflatable tube 6 to prevent gas from flowing back, ensuring that the gas only flows to the inflatable bag 5 and does not return to the inflatable device, thereby preventing the inflatable bag 5 from deflation when in use.

[0024] The following is a detailed description of the design of the above key components:

[0025] The material of the mouth cover 1 is medical non-woven fabric. Medical non-woven fabric has air permeability and antibacterial properties. When used as the material of the mouth cover 1, it can effectively isolate the contact with the patient's oral cavity and reduce the risk of infection caused by contact with the mucous membrane.

[0026] One end of the inflatable tube 6 is connected to the inflatable device and passes through the mouth pad 2, and the other end is connected to the inflatable bag 5. The inflatable device and the inflatable bag 5 are connected through the inflatable tube 6, so that the gas flows from the inflatable device into the inflatable bag 5, and the inflatable bag 5 is filled to support the patient's throat airway.

[0027] The inflatable device is an inflatable ball 8. As a form of inflatable device, the inflatable ball 8 can be squeezed to allow gas to flow into the inflatable bag 5, thereby realizing a manual quick inflation function.

[0028] The inflation device is an air injection cylinder 9. As a form of an inflation device, the air injection cylinder 9 is pushed to allow gas to flow into the inflation bag 5, thereby realizing a manual rapid inflation function.

[0029] The front end of the air injection tube 4 is made of hard material and the rear end is made of soft material. The front end of the air injection tube 4 is made of hard material to maintain the stability and strength of the tube to avoid deformation caused by the patient's teeth occlusion, while the rear end is made of soft material to improve the patient's comfort and reduce irritation to the patient's throat.

[0030] The mouth pad 2 is in a circular shape with a soft filler inside. The circular design can better fix the patient's mouth and ensure the stability of the insertion of the air injection tube 4. The soft filler inside can make the patient more comfortable and provide additional cushioning protection, while facilitating the passage of the inflation tube 6.

[0031] The contents not described in detail in this specification belong to the prior art known to professionals in this field.

[0032] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
