Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, and in particular to a prone position ventilation treatment device for oral intubated patients. Background Art

[0002] Prone ventilation is an important respiratory support strategy widely used to treat patients with severe lung diseases such as acute respiratory distress syndrome (ARDS). By shifting the patient from a supine to a prone position, the ventilation / perfusion ratio in the lungs is improved, promoting the expansion of collapsed alveoli on the back, thereby effectively increasing arterial oxygenation levels.

[0003] In current clinical practice, the treatment and care of intubated patients requiring prone ventilation usually relies on the combined use of multiple independent devices. This generally includes an intensive care bed, an independent mechanical ventilator, a negative pressure suction device, and various pillows for position fixation. However, this treatment environment composed of multiple decentralized devices has inherent shortcomings. First, the simultaneous operation of multiple devices makes the space next to the patient's bed extremely crowded, and a large number of tubes and wires are intertwined, which not only brings inconvenience to the clinical operations of medical staff, but also increases the risk of accidental detachment or kinking of the tubes, posing a potential threat to patient safety.

[0004] Furthermore, prolonged prone positioning places constant pressure on the face, chest, and pelvis. This, combined with the accumulation of sweat and secretions creating a moist environment, can easily lead to complications such as pressure injuries and skin maceration. Existing care methods rely primarily on manual, timed turning and the use of single-function, pressure-relieving mattresses. This not only increases the workload for medical staff but also has limited effectiveness in proactively improving the patient's skin microenvironment.

[0005] In summary, current treatment options for prone ventilation patients leave room for improvement in terms of device integration, ease of use, and complication prevention. Therefore, developing a structurally integrated, fully functional prone ventilation device that effectively addresses these challenges has become a pressing technical challenge in this field.

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the specification of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0036] In order to better understand the present invention, the above contents are described in detail below in conjunction with specific embodiments.

[0037] Refer to the attached Figure 1 and attached Figure 2 This embodiment provides a prone ventilation treatment device for oral intubated patients, which includes a treatment bed 1 as a basic platform, and a breathing mechanism 2, an air circulation mechanism 3 and a sputum suction mechanism 4 arranged inside the treatment bed 1.

[0038] Refer to the attached Figure 1 An air cushion 101 is fixedly connected to the top of the treatment bed 1, and the air cushion 101 is used to provide support for the patient in a prone position. In order to adapt to the patient's prone posture and treatment needs, a head placement opening 102 is opened on the top surface of the air cushion 101. The head placement opening 102 is set so that the patient's face can be placed in the opening when lying prone, thereby avoiding direct pressure on the eyes, nose and mouth. An intubation hole 103 is also opened on the top of the air cushion 101. The intubation hole 103 provides a smooth and fixed channel for the gas intubation delivered by the subsequent breathing mechanism 2 to be connected to the patient's tracheal intubation.

[0039] Refer to the attached Figure 2 The breathing mechanism 2, air circulation mechanism 3 and sputum suction mechanism 4 are all integrated and installed in the internal cavity of the treatment bed 1. This integrated structural layout makes the overall structure of the equipment compact and convenient for unified management and maintenance. In the subsequent description, the specific structure and working mode of each mechanism will be explained in detail.

[0040] Refer to the attached Figure 2 - Attachment Figure 6 , the breathing mechanism 2 in this embodiment is described in detail. The breathing mechanism 2 is used to generate and deliver therapeutic gas.

[0041] The breathing mechanism 2 includes a drive motor 201 fixedly connected to the interior of the treatment bed 1, serving as a power source. The output end of the drive motor 201 is fixedly connected to a drive shaft 203. A pulley 1 204 is fixedly connected to the exterior of the drive shaft 203. A support rod 202 is fixedly connected to the bottom end of the treatment bed 1. The top of the support rod 202 is rotatably connected to a pulley 2 205. A belt 1 206 is interposed between pulleys 1 204 and 205, forming a transmission system. When the drive motor 201 is operating, its rotational motion is transmitted to pulley 2 205 via the drive shaft 203, pulley 1 204, and belt 1 206, causing it to rotate around the top of the support rod 202.

[0042] Refer to the attached Figure 3 and attached Figure 4A half gear 209 is fixedly connected to the outside of the second pulley 205, and a ring gear 208 that can slide horizontally inside the treatment bed 1 is meshed with the half gear 209. Since the half gear 209 has only half a circle of teeth, when it rotates with the second pulley 205, it will periodically mesh with the ring gear 208 and push it to one side, and then disengage from the ring gear 208 during the other half circle of rotation. At this time, the ring gear 208 is reset under the action of the subsequent mechanism. In this way, the continuous rotational motion of the half gear 209 is converted into the reciprocating linear motion of the ring gear 208.

[0043] Refer to the attached Figure 3 and attached Figure 5 The side of the ring gear 208 away from the drive motor 201 is fixedly and slidably connected to a pump rod 211, and the outside of the pump rod 211 is slidably connected to an air compression pump 210, and the air compression pump 210 itself is fixedly connected to the inside of the treatment bed 1. The end of the pump rod 211 away from the ring gear 208 is fixedly connected to a piston 213, and the piston 213 is slidably connected to the internal pump chamber of the air compression pump 210. The reciprocating linear motion of the ring gear 208 directly drives the piston 213 through the pump rod 211 to perform reciprocating suction and compression strokes in the air compression pump 210. Inside the air compression pump 210, one side of the piston 213 is fixedly connected to a filter screen 212. When the piston 213 performs the suction stroke, the external air must first be filtered through the filter screen 212 to remove foreign particles therein before entering the pump chamber.

[0044] Refer to the attached Figure 3 , Attachment Figure 5 and attached Figure 6 The side of the air compressor 210 away from the ring gear 208 is connected to the conversion box 216 via an air supply pipe 214. A one-way valve 215 is fixedly connected to the outside of the air supply pipe 214. This one-way valve 215 ensures that the compressed gas can only flow from the air compressor 210 to the conversion box 216 and cannot flow back in the opposite direction. A pressure valve 217 is set on the top of the conversion box 216 to stabilize and limit the pressure of the gas entering the box. The bottom of the conversion box 216 is connected to the oxygen supply box 207 via an air supply pipe 218. A one-way valve 219 is also fixedly connected to the air supply pipe 218 to ensure the one-way flow of gas. The oxygen supply box 207 is used to store or mix gas. A pressure valve 220 is fixedly connected to its top to control the pressure of the final output gas.

[0045] Finally, the regulated gas is output from the oxygen supply box 207 away from the side of the conversion box 216 through the oxygen supply pipe 221. The top of the oxygen supply pipe 221 is fixedly connected to the oxygen cannula 222. The oxygen cannula 222 passes through the cannula hole 103 on the air cushion 101 and is connected to the patient's tracheal cannula.

[0046] Refer to the attached Figure 2 , Attachment Figure 7 and attached Figure 8 The air circulation mechanism 3 in this embodiment is described in detail. The air circulation mechanism 3 is used to form a flowing air layer around the patient's body. The power of the air circulation mechanism 3 also comes from the aforementioned drive motor 201. Specifically, the output end of the drive motor 201 is specifically a drive shaft 203 on which a pulley 301 is fixedly connected. While driving the breathing mechanism 2, the drive motor 201 also drives the air circulation mechanism 3 to work.

[0047] The air circulation mechanism 3 includes an air filter pump 304 fixedly connected to the interior of the treatment bed 1. An air extractor 305 is fixedly connected to the interior of the air filter pump 304. The input end of the air extractor 305 is fixedly connected to a pulley 4 302. A belt 2 303 is installed between the pulley 3 301 and the pulley 4 302. When the drive motor 201 is working, its rotational power is transmitted to the pulley 4 302 through the pulley 3 301 and the belt 2 303, thereby driving the air extractor 305 to rotate and inhale air.

[0048] Refer to the attached Figure 7 and attached Figure 8 The air filter pump 304 is fixedly connected to an air filter plate 306 on the side away from the exhaust fan 305. The external air sucked in by the exhaust fan 305 flows inside the air filter pump 304 and is forced to pass through the air filter plate 306. The air filter plate 306 is used to filter dust and suspended particles in the air to output clean air. Two connecting pipes 307 are fixedly connected to the outside of the air filter pump 304. The air purified by the air filter plate 306 is transported out through the two connecting pipes 307. The top of each connecting pipe 307 is fixedly connected to an air supply plate 308. The two air supply plates 308 are respectively fixedly connected to the left and right sides of the air cushion 101 on the top of the treatment bed 1. A plurality of air supply holes 309 are opened on the top surface of the air supply plate 308. The clean air transported from the connecting pipe 307 is distributed through the inner cavity of the air supply plate 308 and is evenly blown out from these air supply holes 309, thereby forming a continuous, flowing air layer around the patient's prone body.

[0049] Refer to the attached Figure 9 , the sputum suction mechanism 4 in this embodiment is described in detail. The sputum suction mechanism 4 is used to clear secretions in the patient's respiratory tract as needed, and is set in the device as an independent functional unit.

[0050] The sputum suction mechanism 4 includes a controller 401, the bottom of which is fixedly connected to the inner bottom end of the treatment bed 1. A power device for generating negative pressure is integrated inside the controller 401. At the top of the controller 401, a sputum suction bucket 402 and a processing bucket 403 are slidably connected. The sputum suction bucket 402 is used to collect sputum and secretions sucked out of the patient's body. The top of the processing bucket 403 is fixedly connected to a U-shaped tube 404. The U-shaped tube 404 forms an air path connection with the negative pressure source of the controller 401 and the sputum suction bucket 402, which is used to prevent the liquid in the sputum suction bucket 402 from being accidentally sucked into the power device of the controller 401. The top of the sputum suction bucket 402 is fixedly connected to a sputum suction tube 405, which is a flexible pipe. The top of the sputum suction tube 405, that is, the end away from the sputum suction bucket 402, is fixedly connected to a sputum suction cannula 406.

[0051] When suctioning is required, the medical staff activates controller 401, activating its internal power unit and generating negative pressure. This negative pressure is transmitted to suction bucket 402 via U-shaped tube 404. The negative pressure is then transmitted via suction tube 405 to the end of suction cannula 406. The medical staff inserts suction cannula 406 into the patient's endotracheal tube. The negative pressure then draws out sputum and secretions from the airway, which flow through the tube and are collected in suction bucket 402.

[0052] Working Principle: This device is an integrated treatment bed 1 designed to provide a complete support environment for intubated patients requiring prone ventilation. Its core is a main drive motor that simultaneously drives two key systems: the respiratory mechanism 2 and the air circulation mechanism 3. In addition, the device also integrates a suction mechanism 4 for clearing the patient's airway. The entire system is designed on a custom-made treatment bed 1, whose air cushion 101 has specialized openings to accommodate the patient's facial and head placement port 102 and the endotracheal tube port 103.

[0053] Breathing mechanism 2 simulates a ventilator, providing mechanical ventilation to the patient. Drive motor 201 activates pulley 1 204 and belt 1 206 on its output shaft, driving pulley 205. This causes half gear 209, coaxially fixed to pulley 205, to rotate accordingly. As a half gear, its rotation periodically engages and disengages with ring gear 208, causing the connected ring gear 208 to produce reciprocating linear motion. The reciprocating motion of ring gear 208 drives piston 213 through pump rod 211, which reciprocates within the cylinder of air compressor pump 210. When piston 213 moves to one side, it draws in air filtered by filter 212. When it moves to the other side, it compresses the air. The compressed gas passes through air supply pipe 214 and one-way valve 1 215 and is then forced into switch box 216. Switch box 216 serves as a gas storage and pressure regulator. Pressure valve 1 217 at its top prevents excessive pressure. Gas then flows from the bottom of switch box 216 through air supply pipe 218 and one-way valve 219 to oxygen supply box 207, which stores or mixes gas with an external oxygen source. Pressure valve 220 at its top also serves as a safety feature. Finally, the regulated therapeutic gas is delivered to the patient through oxygen supply pipe 221 and oxygen cannula 222 at the end. Oxygen cannula 222 passes through cannula hole 103 in air cushion 101 and is connected to the patient's endotracheal tube.

[0054] The function of the air circulation mechanism 3 is to provide a dry, air-circulating microenvironment for prone patients to prevent bedsores and skin infections. It shares the same drive motor 201 with the respiratory mechanism. The other end of the motor output shaft is connected to pulley three 301, which drives pulley four 302 to rotate through belt two 303, thereby driving the exhaust fan 305 inside the air filter pump 304 to work. The exhaust fan (305) inhales air from the surrounding environment from one end. The air flows through the inside of the air filter pump 304 and is filtered through the air filter plate 306 at the other end to remove dust and impurities. The clean air is transported to the air supply plate 308 installed on both sides of the air cushion 101 through the connecting pipe 307. There are many air supply holes 309 on the air supply plate. The clean air is blown out evenly from these small holes, surrounding the patient's body to form a ventilation layer.

[0055] The sputum suction mechanism 4 is independent of the two aforementioned systems and is used to clear sputum and secretions from the patient's airway as needed. It consists of a controller 401 with a vacuum pump, a sputum suction bucket 402 for collecting sputum, and a disposal bucket 403 for storing cleaning fluid or waste liquid. When a medical professional activates the controller 401, the vacuum pump within the controller 401 begins to operate, generating negative pressure. A sterile sputum suction cannula 406 is connected to the sputum suction bucket 402 via a sputum suction tube 405. The cannula 406 is then inserted into the patient's endotracheal tube. Under the action of the negative pressure, sputum in the patient's airway is sucked out, flowing along the tube into the sputum suction bucket 402 and collected. A U-shaped tube 404 and disposal bucket 403 prevent liquid from being sucked back into the controller 401.

[0056] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
