Description

Technical Field

[0001] The present invention relates to the field of medical devices, and particularly to an electric low-frequency jet ventilation device. Background Art

[0002] In the existing clinical practice, low-frequency jet ventilation is mostly used in surgeries or treatment processes that require a long exhalation time and reduce the risk of gas retention. It is particularly suitable for cases of airway stenosis or obstruction, such as certain otolaryngology surgeries and endotracheal treatment surgeries. Traditional low-frequency jet ventilation systems usually rely on manual operation, cannot adjust the oxygen concentration, and cannot accurately control the respiratory rate and respiratory ratio. The accuracy of the air flow pressure controlled manually is relatively low, which easily leads to too high or too low airway pressure, thus increasing the risk of barotrauma or hypoventilation for patients. In addition, the manual system is complex to operate and requires medical staff to have a high level of skills and attention, which increases the labor cost and the possibility of operation errors.

[0003] In addition, in special fields such as difficult airway management, pediatrics, and airway intervention surgeries, patients usually have problems such as respiratory tract stenosis, respiratory insufficiency, and inability to use conventional airway tools (such as endotracheal tubes, laryngeal masks). This poses higher requirements for the performance of ventilation devices. Low-frequency jet ventilation is more suitable for the needs of these patients due to its longer exhalation time, lower airway pressure, and the ability to retain the natural airway without using traditional airway tools. However, traditional manual systems are difficult to meet these delicate ventilation requirements, especially in surgeries that require long hours or high concentration of attention. Summary of the Invention

[0004] In view of the problems in the background art, the purpose of the present invention is to provide an electric low-frequency jet ventilation device that can provide oxygen with adjustable concentration and achieve precise oxygen supply.

[0005] To achieve the above object, the present invention provides an electric low-frequency jet ventilation device, which includes: a box body provided with an air inlet and an air outlet; an oxygen storage tank disposed inside the box body and fixedly connected to the inner wall of the box body; an oxygen pump disposed inside the box body and fixedly connected to the inner wall of the box body, connecting the oxygen storage tank; an oxygen pressure sensor connecting the oxygen storage tank and an oxygen gas source outside the box body; an oxygen proportional valve connecting the oxygen pump; an air storage tank disposed inside the box body and fixedly connected to the inner wall of the box body; an air pump disposed inside the box body and fixedly connected to the inner wall of the box body, connecting the air storage tank; an air pressure sensor connecting the air storage tank and an air gas source outside the box body; an air proportional valve connecting the air pump; a three-way valve disposed inside the box body, connecting the oxygen proportional valve, the air proportional valve and an oxygen delivery conduit; an air intake waterproof fan blade disposed on two side walls of the box body; a foot cup disposed at the bottom of the box body for supporting the box body; a handle fixedly provided in the middle of the upper surface of the box body; a control circuit board fixedly connected to the inner wall of the box body and electrically connected to the oxygen storage tank, the oxygen pump, the oxygen pressure sensor, the oxygen proportional valve, the air storage tank, the air pump, the air pressure sensor, the air proportional valve and the three-way valve; a display screen disposed in the middle of an outer surface of the box body and electrically connected to the control circuit board; and a rotary switch disposed on the outer surface of the box body and electrically connected to the control circuit board.

[0006] In one embodiment, the oxygen gas source is an oxygen storage tank disposed outside the box body; the air gas source is an air storage tank disposed outside the box body.

[0007] In one embodiment, the oxygen gas source is a central oxygen supply system; the air gas source is external air.

[0008] In one embodiment, the oxygen concentration provided by the electric low-frequency jet ventilation device is 30%-100%.

[0009] In one embodiment, the gas pressure released by the electric low-frequency jet ventilation device is 0.1-4 bar.

[0010] The beneficial effects of the present invention are as follows:

[0011] 1. Improve patient safety

[0012] The electric low-frequency jet ventilation device of the present invention can significantly reduce potential risks in traditional manual systems, such as barotrauma, hypoventilation and oxygen toxicity, etc., by precisely controlling the gas pressure (released gas pressure), ventilation frequency, inspiratory-expiratory ratio and oxygen concentration. The precise control can ensure that patients can obtain stable and safe respiratory support during complex airway management and surgical procedures.

[0013] 2. Expand the scope of application

[0014] The complexity of the manual operation of existing low-frequency jet ventilation limits its use in a wider range of clinical scenarios. For example, it cannot be applied in long-term airway surgeries. The low-frequency jet ventilation device of the present invention can be applied in airway intervention surgeries, bronchoscopies, difficult airway management, and other surgeries that require a longer expiratory time due to its automated operation.

[0015] 3. Reduce the burden on medical staff

[0016] The electric low-frequency jet ventilation device of the present invention reduces the skill requirements and workload of medical staff through automated operation, enabling medical staff to easily manage complex respiratory support even in emergency or resource-limited situations. This not only improves work efficiency but also reduces the possibility of operation errors. Brief Description of the Drawings
