Description

Technical Field

[0001] This utility model relates to the field of medical devices, specifically to a pediatric infection prevention and isolation auxiliary device with a high-efficiency ventilation structure. Background Technology

[0002] Children's immune systems are not yet fully developed and their resistance is weak. They are highly susceptible to airborne droplets, aerosols, and cross-infection sources during hospital visits and hospitalizations. Therefore, pediatric treatment areas usually need to be equipped with independent isolation barriers to isolate and care for children separately and reduce the probability of cross-infection.

[0003] Most existing conventional pediatric isolation devices only have simple physical barrier isolation functions. They are structurally sealed with poor internal air circulation. Prolonged closed environments can easily lead to increased carbon dioxide concentration, turbid air, odor accumulation, and high humidity in the isolation space, which can easily breed bacteria and is detrimental to the health of children. At the same time, existing isolation ventilation equipment has a single ventilation method, mostly using fixed fans to blow air directly, with fixed air outlet direction. This can easily lead to ventilation dead zones and uneven air exchange inside the isolation chamber. Utility Model Content

[0027] The present invention will be further described below with reference to the embodiments.

[0028] Example: Refer to Figures 1 to 5 A pediatric infection prevention and isolation auxiliary device with a high-efficiency ventilation structure includes an isolation auxiliary device body 1.

The transmission component 3 uses the power generated by the operation of the ventilation component 2 to drive the flow guiding components to operate synchronously.

[0030] The ventilation assembly 2 includes a ventilation slot 21 formed on the upper surface of the ventilation box 13. A cross support frame 22 is fixedly connected to the inner wall of the ventilation slot 21. A motor 23 is fixedly connected to the side wall of the ventilation box 13 via a bracket. A first rotating shaft 24 is fixedly connected to the output end of the motor 23. The first rotating shaft 24 is rotatably connected to the inner wall of the ventilation slot 21 through a bearing. A second rotating shaft 25 is provided inside the ventilation slot 21. The second rotating shaft 25 is rotatably connected to the upper surface of the cross support frame 22 through a bearing. A first bevel gear 26 is fixedly connected to the side end of the first rotating shaft 24, and a second bevel gear 27 is fixedly connected to the circumference of the second rotating shaft 25. The first bevel gear 26 and the second bevel gear 27 mesh with each other. An exhaust fan blade 28 is fixedly connected to the top of the second rotating shaft 25. A filter plate 29 is fixedly connected to the inner wall of the ventilation slot 21. The exhaust fan blade 28 is located below the filter plate 29. Both the first bevel gear 26 and the second bevel gear 27 are located inside the ventilation slot 21 and are located below the cross support frame 22.

[0031] The transmission assembly 3 includes a third rotating shaft 31 rotatably connected to the inner wall of the ventilation slot 21 via bearings. The third rotating shaft 31 is rotatably connected to the side wall of the ventilation box 13 via bearings. A driving wheel 32 is circumferentially fixedly connected to the first rotating shaft 24, and a driven wheel 33 is circumferentially fixedly connected to the third rotating shaft 31. A belt 34 is sleeved between the driving wheel 32 and the driven wheel 33. Both the driving wheel 32 and the driven wheel 33 are located outside the ventilation box 13. The diameter of the driving wheel 32 is larger than the diameter of the driven wheel 33.

[0032] The flow guiding assembly 4 includes a flow guiding plate 41 rotatably connected to the inner wall of the ventilation slot 21, a reciprocating threaded rod 42 circumferentially fixedly connected to the third rotating shaft 31, a nut 43 threadedly connected to the reciprocating threaded rod 42, a sleeve 44 fixedly connected to the bottom surface of the flow guiding plate 41, a sliding rod 45 slidably connected inside the sleeve 44, and the bottom end of the sliding rod 45 hinged to the upper surface of the nut 43.

[0033] Ventilation channels 14 are provided between the inner bottom surface and the two side walls of the isolation auxiliary device body 1. Ventilation grilles 15 are fixedly connected to the inner walls of the two ventilation channels 14, and HEPA filters 16 are fixedly installed at the air outlets of the two ventilation channels 14.

[0034] The working principle of this utility model is as follows: During the use of pediatric medical isolation, medical staff place the isolation auxiliary device body 1 stably in the designated position of the ward, and use the circumferential transparent isolation barrier 12 to form a closed and independent isolation space. The transparent material makes it easy for medical staff to observe the mental state and physical condition of the child at any time, without having to open the barrier frequently, thus reducing the probability of external germs invading.

[0035] When the equipment is working normally, motor 23 drives shaft 24 to rotate continuously. Shaft 24 uses bevel gear 26 at its end to drive bevel gear 27 to reverse the direction of rotation, causing shaft 25 to rotate vertically. This drives the exhaust fan blades 28 at the top to rotate at high speed, generating negative pressure suction. Since the airflow guide assembly is located at the upper air inlet, the negative pressure can actively draw clean ambient air from the top ventilation slot 21 into the body of the isolation auxiliary device 1. The incoming airflow is guided and evenly distributed at multiple angles by the reciprocating oscillating guide plate 41. The concentrated airflow is dispersed to avoid strong winds blowing directly on the children. Clean air is guided to diffuse evenly to all areas inside the isolation chamber. The turbid air and stagnant exhaust gas produced by the children's breathing inside the isolation chamber are pushed by air pressure to the bottom and discharged outward through the ventilation channels 14 on both sides of the device. During the exhaust process, the turbid air passes through the ventilation grille 15 and HEPA filter 16 in sequence to intercept and filter droplets, aerosols and germ particles contained in the exhaust gas, so as to avoid the direct discharge of polluted air and cause secondary pollution of the ward, thus completing an orderly air replacement cycle.

[0036] While the No. 1 rotating shaft 24 is rotating, the outer driving wheel 32 rotates synchronously. Through the friction transmission of the belt 34, it drives the driven wheel 33 and the No. 3 rotating shaft 31 to rotate synchronously at an increased speed. The No. 3 rotating shaft 31 drives the reciprocating threaded rod 42 to rotate continuously. Under the constraint of the thread, the nut 43 makes a continuous left-right reciprocating linear motion along the axis of the threaded rod. The nut 43 pushes and pulls the guide plate 41 through the hinged slide rod 45 and sleeve 44, so that the guide plate 41 makes a periodic reciprocating swing at the air inlet of the ventilation slot 21. During the swing, the angle of the airflow at the top is constantly changed, so as to evenly distribute and flexibly guide the incoming clean air. This not only eliminates the ventilation dead corners inside the isolation chamber and makes the airflow inside the chamber circulate slowly and gently, but also avoids the hard direct blowing that would irritate the delicate respiratory system of infants and young children, making it suitable for the medical use environment of weak children.

[0037] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
