Description

Technical Field

[0001] The present invention relates to the field of medical devices, and in particular to a respiratory clinical diagnosis and protection device. Background Art

[0002] Many respiratory diseases are transmitted between people through the respiratory tract, air, and saliva. In clinical practice, medical staff need to diagnose patients face to face, which puts them in an infected state. Especially during the peak period of infectious diseases (such as avian influenza, SARS, and COVID-19), the chance of medical staff being infected increases sharply.

[0003] After extensive searching by our team, we learned that the existing respiratory clinical protection devices mainly include those with publication numbers US4821711A, JPWO2013187278A1, JP2015134165A and CN109431617B. Among them, the respiratory clinician protection device disclosed in CN109431617B is particularly representative. The dental auxiliary instrument is placed in the second receiving chamber 2, and the sliding rear cover structure allows the grasping bracket, auxiliary bracket, and second receiving chamber to be opened. The receiving room is open. When medical staff diagnose patients, if it is a simple one-handed operation, they use the grabbing bracket to grab the medical device in the second receiving room, and the grabbing bracket sends the grabbed medical device to the auxiliary bracket. The auxiliary bracket receives the medical device from the grabbing bracket to diagnose and treat the patient. The medical staff only needs to watch and use the baffle structure to protect the medical staff. If it is a complex diagnosis, the medical staff diagnoses and treats the patient through the baffle structure during diagnosis, and the auxiliary bracket plays an auxiliary role for the medical staff. The device is When in use, the auxiliary bracket is equivalent to a hand of the medical staff, assisting the medical staff in diagnosing the patient. If it is a simple diagnosis, the medical staff can complete the diagnosis of the patient without doing anything. If it is a complex diagnosis, the auxiliary bracket can also assist the medical staff, reducing the labor intensity of the medical staff. Therefore, in order to solve this problem, medical protection devices have been introduced to separate medical staff and patients through a partition to prevent medical staff from being infected. Although the existing protective devices can isolate medical staff from pathogens to a certain extent or use devices to isolate medical staff from patients, when examining patients, medical staff still need to examine patients face to face, especially doctors need to go to the bedside to observe, smell, ask and feel, so there is still a high chance that medical staff will be infected with infectious diseases. Respiratory diseases are mainly transmitted through the respiratory system, and traditional use can also be protected by wearing masks. The existing medical masks have a simple structure, but when they need to be worn for a long time, they need to be tightened against the user's skin for a long time, which also affects comfort.

[0061] Example 3: This example is a further description of the above example. It should be understood that this example includes all the above technical features and is further described in detail:

[0062] Further integration Figure 6 As shown, the protection method of the protection system includes:

[0063] S1. Wearing: Put the head cover 11 on the top of the user's head, and then adjust the telescopic support rod 12 so that the mounting rod 13 is wrapped around the user's neck;

[0064] S2. Visual monitoring: The operator is positioned close to the patient with his head facing the patient so that the camera 31 can capture the patient's face. When the monitoring module 3 recognizes that the patient is about to sneeze or has already sneezed, the control module 5 controls the locking mechanism 23 to release the protective shield 22, causing both protective shields 22 to pop out of the housing 14 and then attract and connect to each other, thereby shielding and isolating the user's respiratory system. At the same time, the jet module 4 is activated to spray air around and in front of the housing 14, thereby blowing away approaching droplets. At the same time, the space between the housing 14 and the user forms a breathing cavity.

[0065] When the monitoring module 3 recognizes that the patient is about to sneeze or has already sneezed, the specific recognition method is as follows: the camera 31 takes a picture to generate a real-time image, and then the analysis unit 32 recognizes and analyzes the real-time image. The recognition and analysis method includes recognizing the person in the real-time image, and simultaneously recognizing the eyes and mouth of the person in the real-time image. When the eyes and mouth of the person are recognized to have the characteristics of the preparatory movement of sneezing, it is determined that there is a risk behavior, and the analysis unit 32 sends an operation request of the locking mechanism 23 to the control module 5;

[0066] When the preparatory movement features of sneezing are identified in the eyes and mouth of the person, the specific method is as follows: the analysis unit marks the upper eyelids and lower eyelids of the left and right eyes of the person in the real-time image, and marks the positions of the nose tip, lip bead, and the center of the lip valley of the person, calculates the distance l1 between the upper eyelid and the lower eyelid, the distance l2 between the nose tip and the lip bead, and the distance l3 between the lip bead and the center of the lip valley in each frame of the image, identifies the image of the patient in the initial state as a reference image, and calculates the first feature contrast amount s1 and the second feature contrast amount s2 of the reference image;

[0067] in

[0068] When s1<k1 and s2>k2, it is determined that there is a preparatory action feature of sneezing; wherein k1 and k2 are comparative reference thresholds obtained through routine experiments and autonomous learning of the analysis unit 32;

[0069] At the same time, the jet module 4 is activated to spray air around and in front of the cover 14, thereby blowing away the approaching droplets. The specific effect is as follows: when the airflow generated by the fan 41 passes through the ventilation channel and blows out from the first air outlet, the inclined first air outlet allows the airflow to be sprayed toward the face and then diffused toward the periphery, thereby forming a wind wall effect, blowing away fine particles close to the side of the cover 14;

[0070] S3, auditory monitoring, while the sound recognition unit 33 recognizes the sound, the sound recognition unit 33 collects the scene sound, and then compares the scene sound with the characteristic sound in the characteristic sound library to analyze whether there is a matching characteristic sound. If there is a match, it is determined that there is a risky behavior;

[0071] The characteristic sounds in the characteristic sound library include sneezing and coughing;

[0072] S4. Breathing. Part of the air sent in by the fan 41 flows into the respiratory airway and then passes through the filter membrane to filter out viruses, bacteria and other waste materials and then is sent into the breathing cavity for the user to breathe. When the user exhales the exhaust gas, the exhaust gas is blown out from the four sides of the cover 14 along the gas flowing out from the first air outlet.

[0073] Reset: When the protective cover 22 needs to be opened, the protective cover 22 is pushed back into the installation cavity so that the buckle portion of the protective cover 22 is buckled and connected with the buckle rod.
