Description

Pediatric airway clearance device

technical field

The invention relates to the field of medical equipment, in particular to a pediatric airway cleaning device.

Background technique

Airway cleaning generally requires the assistance of a sputum suction device. The sputum suction device is mainly used for routine suction and tracheotomy on the wounded and sick. It is generally electric or manual, and is suitable for army companies, battalions, regiments, and divisions. It is suitable for the rescue sputum suction of medical units and the sputum suction of hospitals or any other medical units without power supply. The sputum aspirator has the characteristics of small size, light weight, great attraction, compact structure, easy to carry, low cost, sturdy and durable, etc. When the user is using it, once the patient is a child, he must use a pediatric sputum aspirator. Common sputum suction devices currently on the market are lighter and generally operated manually. Most of the equipment has a relatively simple structure, while automatic sputum suction devices are generally larger in size and inconvenient to carry. However, the patent disclosed in the application announcement number CN110193099B A pediatric sputum aspirator is a manual sputum aspirator. When using it, the user needs to hold the body of the sputum aspirator with one hand and push the manual push-pull rod with the other hand. This operation method cannot keep the sputum aspirator stable and sucks sputum. It is easy to shake during the suction process, which affects the suction effect, and the user cannot adjust the position, angle and depth of the suction tube at will when operating the suction device with two hands. It may take two people to complete the suction operation. It is relatively complicated, and secondly, this device does not have the function of administering medicine to the patient's respiratory tract while sucking sputum, and the functionality is relatively simple, and the parts of this device are relatively loaded down with trivial details, and assembly is very inconvenient.

The above-mentioned positioning groove 39 and positioning rib 40 are for fast positioning when installing the tank body 3, making the installation faster and more convenient. The above-mentioned sealing ring 41 It is to ensure that the inside of the tank body 3 is absolutely sealed after the installation of the tank body 3 is completed, so that the device can be used normally.

working principle:

When using this device, at first stretch the Y-shaped flexible pipe 5 into the position to be cleaned in the patient's respiratory tract and then start the miniature negative pressure pump 7, the suction end on the miniature negative pressure pump 7 starts to inhale, and the air outlet end starts to breathe out at the same time, because The suction end communicates with the interior of the tank 3 below. When the suction end starts to inhale, the air inside the tank 3 will be sucked away to form a negative pressure effect inside the tank 3. When the tank below 3. When the inside is in a negative pressure state, the liquid suction channel 8 on the Y-shaped hose 5 will be forced to generate suction, so that when the Y-shaped hose 5 extends into the patient's respiratory tract to clean up the waste liquid, the waste liquid can be smoothly sucked into the lower chamber. In the tank body 3, since the gas outlet end communicates with the interior of the tank body 3 above, when the gas outlet end starts to discharge gas, the gas will enter the inside of the tank body 3 to generate high pressure inside the tank body 3, when the tank body 3 above When the inside is in a high-pressure state, the medicinal liquid in the tank body 3 will be forced to flow out to the drug delivery channel 9, and flow to the patient's respiratory tract through the drug delivery channel 9 to improve the therapeutic effect. The medicinal liquid can be a therapeutic liquid or an auxiliary cleaning liquid .
