Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular is an airway patency device for critical care respiratory support. Background Art

[0002] Critical care medicine is a first-level clinical discipline that studies the occurrence, development and diagnosis and treatment of life-threatening pathological and physiological conditions. Talents play a major role in this discipline, and very advanced equipment is required. It is a discipline that conducts quantitative monitoring of patients and provides continuous critical care monitoring for critically ill patients throughout the entire course of treatment. In this process, it provides patients with comprehensive treatment. It is an important symbol of the development of modern medicine and a reflection of the level of a discipline and a hospital. Especially in the process of maintaining smooth airway in critical care medicine, airway patency is usually reflected by the flow rate of respiratory gases. The gas flow rate is proportional to the airway diameter. The larger the airway diameter, the smoother the flow rate. On the contrary, if the airway is spasmodic, narrow or blocked, the airway diameter becomes smaller and the gas flow rate slows down. Patients who have just undergone critical surgery may become confused and unable to expel foreign matter such as sputum by themselves. In the prior art, multiple medical staff are generally required to assist the patients, specifically by assisting in the suction of sputum in the patient's mouth and patting the back of critically ill patients to help expel sputum. In order to ensure that the patient has a good and unobstructed airway, this process will inevitably increase the workload of multiple medical staff. Summary of the invention

[0016] The present invention can synchronously drive the L-shaped arc panel to move upward by moving the ring plate frame upward, thereby contacting the outer wall of one side of the bottom end of the L-shaped striking plate, and rotating it at a certain angle on the rotating shaft. When the L-shaped striking plate rotates, it will hit the back of the patient in a side-lying state, so as to assist the patient to cough up sputum as soon as possible and avoid trachea blockage. At the same time, when the L-shaped striking plate rotates, it will also push up the telescopic gravity rod. When the L-shaped arc panel moves downward, the telescopic gravity rod will automatically drive the L-shaped striking plate to reset according to its own weight and no longer contact the patient's back. This can reduce the workload of medical staff and help the patient to clear the sputum as soon as possible. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] It should be added that each straw 131 is also made of elastic material and can generate elastic expansion and contraction under external force.

[0023] The suction structure includes a lifting plate 124 fixedly connected to the outer wall of the bottom end of one side of the ring plate frame 123, and a foreign body box 125 for accommodating sputum is provided below the lifting plate 124. The outer wall of one end of the foreign body box 125 is fixedly connected to the outer wall of a corresponding groove plate 18, and a box plug 126 is tightly connected through the foreign body box 125. Three bellows 127 are fixedly connected through the top of the foreign body box 125. The tops of the three bellows 127 are fixedly connected to the outer wall of the bottom end of the lifting plate 124. The bottom end of the foreign body box 125 is fixedly connected with three telescopic rubber tubes 130. The three telescopic rubber tubes 130 are fixedly connected to the bottom end of the foreign body box 125. A one-way valve 129 is fixedly connected to the position of the tube 130 near the top, and a straw 131 is fixedly connected to the bottom end of the three telescopic rubber tubes 130. Three hollow sliding plates 132 are respectively slidably connected to the inner wall of each straw 131. Four double-ball support rods 133 are movably sleeved on the top of each hollow sliding plate 132. The other end of each group of double-ball support rods 133 is movably sleeved on the inner wall of each straw 131. A baffle 134 is correspondingly slidably connected to the top of each group of double-ball support rods 133. One end of each group of baffles 134 is fixedly connected to the inner wall of the straw 131.

[0024] The above scheme is adopted: when the telescopic electric cylinder 12 moves upward, it will also drive the ring plate frame 123 and the lifting plate 124 installed on one side of the ring plate frame 123 to move upward synchronously, so that the lifting plate 124 can be stretched to the multiple bellows 127 through the moving lifting plate 124, and the sputum in the patient's mouth can be sucked through the multiple suction tubes 131. The suction force generated will also synchronously drive the multiple hollow sliding plates 132 in the suction tubes 131 to move upward synchronously, and each hollow sliding plate 132 that moves upward synchronously will correspondingly drive the multiple double-ball support rods 133 to generate The tilted multiple double-ball struts 133 will partially expand the straw 131, and the baffle 134 installed on each double-ball strut 133 will block and limit each double-ball strut 133 when it is subjected to suction force and produces its maximum tilt angle, so that the sucked sputum can be sucked into the foreign body box 125 more quickly and more effectively for unified collection, and the angle and position of the straw 131 in the patient's mouth can be controlled by manually operating the straw 131.

[0025] The beating structure includes an L-shaped arc panel 135 fixedly connected to one end of the ring plate frame 123, and an L-shaped striking plate 138 can be intermittently fitted on the top of one side of the L-shaped arc panel 135. A telescopic gravity rod 137 is movably sleeved on the top of one side of the L-shaped striking plate 138, and an L-shaped support plate 136 is fixedly connected to the top of the telescopic gravity rod 137. One end of the L-shaped support plate 136 is fixedly connected to the outer wall of one end of a U-shaped frame 1, and a rotating shaft 139 is rotatably connected at the bending point of the L-shaped striking plate 138, and one end of the rotating shaft 139 is fixedly connected to the outer wall of one end of the U-shaped frame 1.

[0026] The above scheme is adopted: the upward movement of the annular plate frame 123 will also synchronously drive the L-shaped arc panel 135 to move upward, thereby contacting the outer wall of one side of the bottom end of the L-shaped striking plate 138, and rotating it at a certain angle on the rotating shaft 139. When the L-shaped striking plate 138 rotates, it will hit the back of the patient who is lying on his side, helping the patient to cough up sputum as soon as possible to avoid trachea blockage. At the same time, when the L-shaped striking plate 138 rotates, it will also push up the telescopic gravity rod 137. When the L-shaped arc panel 135 moves downward, the telescopic gravity rod 137 will automatically drive the L-shaped striking plate 138 to reset according to its own weight and no longer contact the patient's back.

[0027] The working principle and use process of the present invention are as follows: two U-shaped frames 1 are placed on both sides of the patient who lies on his side voluntarily, and the two U-shaped frames 1 are limited on the bed, and then the telescopic electric cylinder 12 on the horizontal plate 11 is started to drive the piston cylinder 13 and the arc rubber plate 14 to move downward synchronously, so that the arc rubber plate 14 contacts and presses against the patient's head. When the arc rubber plate 14 moves downward, it also drives the long rectangular plate 120 to move downward on the vertical rod 19 in the groove plate 18 until the bent T rubber plates 121 at both ends of one side of the long rectangular plate 120 are engaged. The arc rubber plate 14 that moves down to contact the patient's head can be positioned in the corresponding T-shaped groove 122 in the groove plate 18, so that when the telescopic electric cylinder 12 moves up, the ball rod 15 installed on the telescopic electric cylinder 12 can no longer drive the connected piston cylinder 13 to move up synchronously. The ball rod 15 that is driven to move up will be separated from the clamping of the ball groove 17 under the action of force, so as to slide up on the arc groove 16, thereby helping the patient's head to continue to lie on its side and preventing the tongue in the patient's mouth from blocking the respiratory duct; At the same time, when the telescopic electric cylinder 12 moves upward, it will also drive the ring plate frame 123 and the lifting plate 124 installed on one side of the ring plate frame 123 to move upward synchronously, so that the lifting plate 124 can stretch to the multiple bellows 127 through the upward moving lifting plate 124, so that each bellows 127 can generate a suction force, and then the sputum in the patient's mouth is sucked through the multiple suction pipes 131 on the bottom end of the foreign body box 125. The generated suction force will also synchronously drive the multiple hollow sliding plates 132 in the suction pipes 131 to move upward synchronously, and each hollow sliding plate 132 that moves upward synchronously will correspondingly drive the multiple double-ball struts 133 to tilt, so that the tilted multiple double-ball struts 133 will expand the part of the suction pipe 131, and the baffle 134 installed on each double-ball strut 133 will make each double-ball strut 1 When the suction force is applied, and the maximum tilt angle is generated, the suction tube 131 will be blocked and limited, so that the sucked sputum can be sucked into the foreign body box 125 faster and more effectively for unified collection. Each suction tube 131 corresponds to the telescopic rubber tube 130 connected to the foreign body box 125. The suction tube 131 can be manually operated to control the angle and position of the suction tube 131 in the patient's oral cavity, so as to quickly suck the sputum in the oral cavity, so that the patient can have a good airway smooth effect. When the lifting plate 124 passively moves downward to drive each bellows 127 to generate an extrusion force, the generated extrusion gas will directly enter the foreign body box 125, and the one-way valve 129 installed on each telescopic rubber tube 130 will only make the sputum enter the foreign body box 125 but not leave it. At the same time, the upward movement of the ring plate frame 123 will also synchronously drive the L-shaped arc panel 135 to move upward, thereby contacting the outer wall of one side of the bottom end of the L-shaped striking plate 138, and rotating it at a certain angle on the rotating shaft 139. When the L-shaped striking plate 138 rotates, it will hit the back of the patient who is lying on his side, helping the patient to cough up sputum as soon as possible to avoid trachea blockage. At the same time, when the L-shaped striking plate 138 rotates, it will also push up the telescopic gravity rod 137. When the L-shaped arc panel 135 moves downward, the telescopic gravity rod 137 will automatically drive the L-shaped striking plate 138 to reset according to its own weight, and no longer contact the patient's back, which can reduce the workload of medical staff and help patients clear the sputum as soon as possible.
