Description

Technical Field

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

[0002] Critical care medicine is mainly established for the rescue and continuous life support of critically ill patients, the treatment and organ function support of patients with multiple organ dysfunction, and the prevention and treatment of multiple organ dysfunction syndrome. In critical care medicine, respiratory support is a crucial link, especially for patients with respiratory tract obstruction by sputum or blood clots. Maintaining a patency of the airway is a prerequisite for effective respiratory support.

[0003] Although there are some effective devices and methods in the existing critical care respiratory support airway patency devices, there are still some shortcomings. For example, for blood clots in the respiratory tract, some devices may not be able to effectively break them up and suck them out, which may cause the blood clots to persist in the respiratory tract and affect the patient's respiratory function.

[0004] In summary, how to solve the problem of blood clot obstruction in the respiratory tract? Some devices may not be able to effectively break and suck it out, which may cause the blood clot to persist in the respiratory tract and affect the patient's respiratory function. This has become a difficult problem that needs to be solved urgently in this field. Therefore, it is necessary to propose an airway clearance device for critical care respiratory support. Summary of the invention

[0005] To solve the above problems, the present invention provides an airway patency device for critical care respiratory support, which is used to effectively clear blood clots and sputum in the respiratory tract of critically ill patients, ensure airway patency, improve respiratory support efficiency, and reduce the risk of complications caused by airway obstruction.

[0006] In order to achieve the above-mentioned purpose, the technical solution of the present invention is as follows: an airway clearance device for critical care respiratory support, comprising a neck pillow, a controller and an intelligent control system; a neck groove is opened on the neck pillow; a support rod is fixedly connected to the side wall of the neck pillow, and a base is fixedly connected to the end of the support rod away from the neck pillow, and a first rack is fixedly connected to the top of the base, and the first rack is meshed with a gear.

[0007] The top of the base is also fixedly connected to a first electric cylinder, the gear and the output shaft of the first electric cylinder are rotationally matched, and the controller is used to control the extension and retraction of the output shaft of the first electric cylinder.

[0008] A linear rail is also fixedly connected to the top of the base, a slider is slidably matched on the linear rail, a second rack is fixedly connected to the side wall of the slider, and the gear is also meshed with the second rack.

[0009] One end of the second rack is fixedly connected with a connecting rod, and one end of the connecting rod away from the second rack is provided with a clamping assembly for clamping the breathing cannula.

[0010] The technical principles of the above scheme are as follows:

[0011] Place the patient's neck in the neck groove on the neck pillow, and the medical staff controls the first electric cylinder to extend through the controller, driving the slider to slide on the linear rail and then driving the second rack to drive the clamping assembly to extend. The medical staff inserts the respiratory trachea into the patient's airway and fixes the respiratory trachea through the clamping assembly. The patient's respiratory rate is monitored in real time through the intelligent control system. When the patient has difficulty breathing or the airway is blocked, the intelligent system sends an alarm to prompt the medical staff to clean the blood clots in the patient's airway. The medical staff removes the respiratory trachea, inserts the suction tube into the patient's airway, and fixes the suction tube through the clamping assembly. At the same time, the clamping assembly can stir the suction tube during suction so that the suction tube can stir and break the blood clots in the airway, and then the sputum and the broken blood clots are sucked out through the suction tube, thereby realizing the operation of cleaning the blood clots and sputum in the airway.

[0012] The above scheme has the following beneficial effects:

[0013] 1. The clamping assembly designed in the present invention can not only maintain stability when fixing the respiratory cannula, but also can be operated by the controller to appropriately stir the sputum suction tube when blood clots need to be cleaned. This stirring action can effectively break up the blood clots in the respiratory tract, making it easier to be sucked out by the sputum suction tube, thereby significantly improving the efficiency of blood clot cleaning.

[0014] 2. The design of the neck pillow of the present invention is ergonomic, which can reduce the pressure on the patient's neck and improve comfort. At the same time, the intelligent control system monitors the patient's breathing status in real time, and immediately alarms once an abnormality is found, so that medical staff can respond quickly and take necessary treatment measures.

[0015] 3. The airway patency device of the present invention integrates intelligent control and automated operation, greatly simplifying the workflow of medical staff. Medical staff only need to perform simple operations through the controller to complete tasks such as fixing the respiratory cannula, cleaning blood clots, and replacing the sputum suction tube, thereby saving precious time and improving the efficiency and quality of medical care.

[0016] Furthermore, the clamping assembly includes a fixed tube, the bottom of which is rotatably matched with a first sleeve, a ring rack is sleeved and fixed on the side wall of the first sleeve, and the bottom of the first sleeve is an inclined surface.

[0017] The bottom of the first sleeve is rotatably matched with the second sleeve, and a ring rack is also sleeved and fixed on the side wall of the second sleeve. The top and bottom of the second sleeve are both inclined.

[0018] The bottom of the second sleeve is rotatably matched with the third sleeve, and a ring rack is also sleeved and fixed on the side wall of the third sleeve. The top of the third sleeve is an inclined surface.

[0019] The fixed cylinder, the first sleeve, the second sleeve and the third sleeve are all interconnected, and the side walls of the fixed cylinder, the first sleeve and the second sleeve are fixedly connected with a driving member, and the output shaft of the driving member is coaxially fixedly connected with a driving gear, and the driving gear is meshed with the adjacent annular rack, and the controller is used to control the output shaft of the driving member to rotate to drive the driving gear to rotate.

[0020] Beneficial effects: The fixed tube, the first sleeve, the second sleeve and the third sleeve can realize multi-stage rotation through the meshing of the annular rack and the driving gear. This design can not only provide stable support when fixing the respiratory cannula or the suction tube, but also can operate the driving member through the controller to drive the driving gear to rotate when blood clots need to be cleaned, so that the sleeves at each level can rotate relative to each other, and the suction tube can be stirred in a snake-like manner like a human hand. This stirring method is softer than rotary stirring, and combined with the flexible material of the suction tube, this stirring method can further increase the stirring efficiency.

[0021] Furthermore, a tube-binding rubber sleeve in the shape of an inverted truncated cone for binding the breathing tube is fixedly connected to the bottom of the third sleeve.

[0022] Beneficial effect: The inverted frustum cone-shaped tube-binding rubber sleeve fixedly connected at the bottom of the third sleeve is used to bind the breathing tube, while increasing the friction between the tubes, which helps to stabilize the breathing tube and prevent it from falling off or shifting.

[0023] Furthermore, the bundle tube rubber sleeve is made of medical silicone material.

[0024] Beneficial effects: The bundle tube rubber sleeve is made of medical silicone, which has excellent aging resistance, high temperature resistance and biocompatibility. In the medical environment, medical silicone can maintain its elasticity and softness for a long time, increasing the reliability of the device.

[0025] Furthermore, a sponge layer is fixedly connected to the neck groove.

[0026] Beneficial effects: The sponge layer can play a certain cushioning role, reducing the friction and damage to the neck caused by movement or rotation of the head.

[0027] Furthermore, an angle adjustment component for adjusting the angle of the neck pillow is provided at the bottom of the neck pillow.

[0028] The angle adjustment component includes a support plate, the top of the support plate is fixedly connected to the bottom of the neck pillow, the bottom of the support plate is hinged with a base plate, the top of the base plate is symmetrically hinged with a second electric cylinder, the output shafts of the second electric cylinders are hinged to the bottom of the support plate, and the controller is used to control the extension and retraction of the output shaft of the second electric cylinder to adjust the angle between the base plate and the support plate.

[0029] Beneficial effects: Adjusting the angle between the base plate and the support plate can accommodate patients of different body sizes, allowing the device to be adjusted according to patients of different body sizes, so that the patient's head and airway remain level when breathing, alleviating patients' breathing difficulties caused by posture, and ensuring that they maintain a comfortable posture when receiving respiratory support.

[0030] Furthermore, a touch screen is fixedly connected to the side wall of the base, and the controller is used to receive user operation signals sent by the touch screen, and control the extension and retraction of the output shafts of the first electric cylinder and the second electric cylinder, and the rotation of the output shaft of the driving member based on the user operation signals.

[0031] Beneficial effects: Through the touch screen, medical staff can conveniently input operating instructions to control the operation of the first electric cylinder, the second electric cylinder and the driving member.

[0032] Furthermore, a photoelectric sensor is fixedly connected to the top of the neck pillow, and a photoelectric sensor is also fixedly connected to the bottom of the connecting rod. The controller is used to receive a photoelectric alignment signal sent by the photoelectric sensor, and control the first electric cylinder to stop running based on the photoelectric alignment signal.

[0033] Beneficial effect: The photoelectric sensors fixedly connected to the top of the neck pillow and the bottom of the second rack can monitor the position of the respiratory cannula and the clamping assembly in real time. When the photoelectric sensor detects that the respiratory cannula or the clamping assembly has reached the predetermined position, it will send a photoelectric alignment signal to the controller, and the controller will control the first electric cylinder to stop running according to the signal. This design ensures that the respiratory cannula and the clamping assembly can be accurately and stably fixed at the predetermined position, improving the accuracy and safety of the operation.

[0034] Furthermore, an alarm is fixedly connected to the side wall of the base, and the controller is used to control the alarm to send out sound and light alarm signals.

[0035] Beneficial effects: The alarm fixedly connected to the side wall of the base can send out sound and light alarm signals when the patient has abnormal conditions such as difficulty breathing or airway obstruction.

[0036] Furthermore, the intelligent control system includes:

[0037] The respiratory monitoring module is used to receive the patient's respiratory rate, respiratory flow and electrocardiogram parameters sent by the ventilator.

[0038] The control module, the controller and the touch screen are electrically connected. The control module is used to receive operation signals of the first electric cylinder, the second electric cylinder and the driving member sent by the touch screen, and use the controller to control the operation of the first electric cylinder, the second electric cylinder and the driving member respectively.

[0039] The safety monitoring and alarm module is used to analyze the patient's respiratory rate, respiratory flow and electrocardiogram parameters and generate analysis results. When the analysis results are one or more of the patient's abnormal respiratory rate, abnormal respiratory flow and abnormal electrocardiogram parameters, an alarm signal is sent to the controller, and the controller controls the alarm to send out an audible and visual alarm signal.

[0040] Beneficial effects: The intelligent control system integrates the respiratory monitoring module, control module, interaction module, and safety monitoring and alarm module to form a complete and efficient medical care system. This system can not only monitor the patient's respiratory status in real time, but also accurately control the operation of each actuator according to the operating instructions of medical staff to ensure that the airway patency device can work according to the predetermined program. At the same time, the existence of the safety monitoring and alarm module enables the system to issue an alarm signal in time when the patient's respiratory status is abnormal, reminding medical staff to take necessary treatment measures, thereby effectively reducing the risk of complications caused by airway obstruction.

The output shaft of the driving member 17 is coaxially fixedly connected with a driving gear 18 by screws. The driving gear 18 is meshed with the adjacent annular rack 14. The controller is used to control the output shaft of the driving member 17 to rotate to drive the driving gear 18 to rotate.

[0057] The bottom of the third sleeve 16 is fixedly connected with a tube-binding rubber sleeve 19 in the shape of an inverted truncated cone for binding the breathing cannula. The tube-binding rubber sleeve 19 is made of medical silicone material.

[0058] A sponge layer is fixedly bonded on the neck groove 2. An angle adjustment component for adjusting the angle of the neck pillow 1 is provided at the bottom of the neck pillow 1.

[0059] The angle adjustment component includes a support plate 20, the top of the support plate 20 is fixedly connected to the bottom of the neck pillow 1 by screws, the bottom of the support plate 20 is hinged with a base plate 21, the top of the base plate 21 is symmetrically hinged with a second electric cylinder 22, and the output shafts of the second electric cylinders 22 are hinged to the bottom of the support plate 20. The controller is used to control the extension and retraction of the output shaft of the second electric cylinder 22 to adjust the angle between the base plate 21 and the support plate 20.

[0060] A touch screen 23 is fixedly connected to the side wall of the base 4 by screws.

[0061] The top of the neck pillow 1 is fixedly connected with a photoelectric sensor 24 by screws, and the bottom of the connecting rod 11 is also fixedly connected with a photoelectric sensor 24 by screws. The controller is used to receive the photoelectric alignment signal sent by the photoelectric sensor 24, and control the first electric cylinder 7 to stop running based on the photoelectric alignment signal.

[0062] An alarm 25 is also fixedly connected to the side wall of the base 4 by screws, and the controller is used to control the alarm 25 to send out sound and light alarm signals.

[0063] Intelligent control system includes:

[0064] The respiratory monitoring module is used to receive the patient's respiratory rate, respiratory flow and electrocardiogram parameters sent by the ventilator.

[0065] The control module, the controller and the touch screen 23 are electrically connected. The control module is used to receive operation signals of the first electric cylinder 7, the second electric cylinder 22 and the driving member 17 sent by the touch screen 23, and use the controller to control the operation of the first electric cylinder 7, the second electric cylinder 22 and the driving member 17 respectively.

[0066] The safety monitoring and alarm module is used to analyze the patient's respiratory rate, respiratory flow and electrocardiogram parameters and generate analysis results. When the analysis results are one or more of the patient's abnormal respiratory rate, abnormal respiratory flow and abnormal electrocardiogram parameters, an alarm signal is sent to the controller, and the controller controls the alarm 25 to send out an audible and visual alarm signal.

[0067] The specific implementation process is as follows:

[0068] First, the airway patency device for critical medical respiratory support of the present invention is placed on the bed in the intensive care unit to ensure that it is stable and motionless. Then, the patient's neck is placed flat in the neck groove 2 of the neck pillow 1. The sponge layer on the neck groove 2 can fill the gap between the patient's head and neck and the neck groove 2, so that the patient's head and neck remain relatively stable, and the intracranial pressure fluctuation of the patient caused by the excessive contact between the patient's head and neck and the neck groove 2 is reduced.

[0069] by Figure 1 and Figure 2 For example, the medical staff inputs an operation instruction through the touch screen 23, and after receiving the instruction, the controller starts to control the output shaft of the first electric cylinder 7 to extend.

[0070] Since the gear 6 rotates in coordination with the output shaft of the first electric cylinder 7, the gear 6 meshes with the first rack 5 and the second rack 10 at the same time. Therefore, when the first electric cylinder 7 extends, it drives the second rack 10 and then drives the slider 9 to slide to the right on the linear rail 8, thereby driving the connecting rod 11 to move to the right.

[0071] During the process of the connecting rod 11 moving to the right, when the photoelectric sensor 24 at the bottom of the connecting rod 11 and the photoelectric sensor 24 at the top of the neck pillow 1 are aligned, the photoelectric sensor 24 sends a photoelectric alignment signal to the controller, and the controller sends a control signal to control the output shaft of the first electric cylinder 7 to stop extending, and finally the fixed cylinder 12 is moved to the position above the patient's mouth. At the same time, this automatic alignment method avoids the waste of time caused by manual alignment by medical staff.

[0072] Compared with the single-stroke structure of the traditional telescopic mechanism, the present invention can amplify the telescopic stroke of the output shaft of the first electric cylinder 7 through the cooperation between the first rack 5, the second rack 10 and the gear 6, so that the stroke of the second rack 10 is doubled, which can be significantly larger than the stroke of the single-stroke structure, so that the volume of the telescopic mechanism of the present invention is smaller than that of the traditional telescopic mechanism.

[0073] Through this design, the present invention further saves the limited space of the intensive care unit, while also realizing the telescopic function of the fixed cylinder 12 .

[0074] When the fixing tube 12 moves to the position above the patient's mouth, the medical staff can insert the breathing tube into the patient's airway. When the breathing tube needs to be fixed, the medical staff can insert the breathing tube into the fixing tube 12 in advance, pass it through the tube binding rubber sleeve 19, and then insert it into the patient's airway. At this time, the inner wall of the tube binding rubber sleeve 19 can bind the breathing tube and increase the friction with the breathing tube, which helps to stabilize the breathing tube and prevent it from falling off or shifting, thereby achieving the fixing operation of the breathing tube.

[0075] During the process of inserting a breathing tube into the patient's airway, if the breathing tube is inserted at an incorrect angle, the medical staff operates the output shaft of the driving member 17 to rotate through the touch screen 23. In this embodiment, the driving member 17 is a micro stepping motor.

[0076] by Figure 3 and Figure 4 For example, when the controller controls the micro-stepping motor output shaft on the side wall of the fixed cylinder 12 to rotate, it can drive the driving gear 18 fixedly connected to it by screws to rotate, and then drive the annular rack 14 and then drive the first sleeve 13 to rotate at the bottom of the fixed cylinder 12.

[0077] When the controller controls the output shaft of the micro-stepping motor fixedly connected to the side wall of the first sleeve 13 by screws to rotate counterclockwise, the second sleeve 15 rotates counterclockwise at the bottom of the first sleeve 13. Since the top and bottom of the second sleeve 15 are both inclined, when the second sleeve 15 rotates counterclockwise, it can form an "L" shape with the first sleeve 13, thereby driving the respiratory intubation tube or suction tube in the second sleeve 15 to bend in an "L" shape.

[0078] When the controller controls the output shaft of the micro-stepping motor fixedly connected to the side wall of the second sleeve 15 by screws to rotate clockwise, it can drive the driving gear 18 fixedly connected to it by screws to rotate, and then drive the third sleeve 16 to rotate clockwise at the bottom of the second sleeve 15. Since the top of the third sleeve 16 is an inclined surface, the third sleeve 16 rotates to the left at this time. At this time, the first sleeve 13, the second sleeve 15 and the third sleeve 16 can form a "Z" shape; when the controller controls the output shafts of the micro-stepping motors on the side walls of the first sleeve 13, the second sleeve 15 and the third sleeve 16 to rotate respectively, the angle and position of the respiratory cannula inserted therein can be continuously adjusted to ensure that the respiratory cannula is located directly above the patient's mouth.

[0079] While the patient is receiving respiratory support, the intelligent control system will monitor the patient's respiratory rate, respiratory flow and electrocardiogram parameters in real time.

[0080] Once abnormal conditions such as breathing difficulties or airway obstruction are detected in the patient, the intelligent system will immediately issue an alarm prompt and send out an audible and visual alarm signal through the alarm 25 so that medical staff can respond quickly and take necessary treatment measures.

[0081] The intelligent control system integrates the respiratory monitoring module, control module, interaction module, and safety monitoring and alarm module to form a complete and efficient medical care system. This system can not only monitor the patient's respiratory status in real time, but also accurately control the operation of each actuator according to the operating instructions of medical staff to ensure that the airway patency device can work according to the predetermined program. At the same time, the existence of the safety monitoring and alarm module enables the system to issue an alarm signal in time when the patient's respiratory status is abnormal, reminding medical staff to take necessary treatment measures, thereby effectively reducing the risk of complications caused by airway obstruction.

[0082] In the process of patients receiving respiratory support, it is usually necessary to clean the blood clots and sputum in the respiratory tract twice a day. When it is necessary to clean the blood clots and sputum in the patient's respiratory tract, the medical staff can remove the respiratory cannula, insert the sputum suction tube into the fixed tube 12 and pass it through the bundle tube rubber sleeve 19, so that the sputum suction tube is firmly clamped in the bundle tube rubber sleeve 19, and then insert the sputum suction tube into the patient's airway, and the sputum suction tube is connected to the negative pressure pump. At this time, the negative pressure pump is started, and the medical staff can operate the touch screen 23 to control the rotation of the output shaft of the micro-stepping motor, so that the output shafts of the stepping motors on the side walls of the first sleeve 13, the second sleeve 15 and the third sleeve 16 rotate relative to each other. When the stepping motors rotate relative to each other continuously, the first sleeve 13, the second sleeve 15 and the third sleeve 16 continuously change angles and directions to drive the sputum suction tube to perform a serpentine stirring operation that simulates a human hand. This stirring method is softer than rotary stirring, and at the same time, with the flexible material of the sputum suction tube, it can more effectively suck out the sputum in the respiratory tract.

[0083] During the whole process, the medical staff only needs to perform simple operations through the touch screen 23 to complete the tasks of fixing the respiratory tube, cleaning the blood clots and replacing the suction tube, which greatly simplifies the work process and improves the efficiency and quality of medical care.

[0084] In addition, the present invention also provides an angle adjustment component for the neck pillow 1, allowing medical personnel to adjust the angle of the neck pillow 1 according to the patient's body shape and comfort requirements.

[0085] by Figure 5 For example, when the medical staff needs to lift the patient's head and neck, they control the output shaft of the second electric cylinder 22 to extend by operating the touch screen 23. Since the output shaft of the second electric cylinder 22 is hinged to the bottom of the support plate 20, and the bottom plate 21 and the support plate 20 are hinged, the extension of the output shaft of the second electric cylinder 22 can increase the angle between the bottom plate 21 and the support plate 20, thereby driving the cervical pillow 1 to lift the patient's head and neck. Conversely, when the patient's head needs to be lowered, the touch screen 23 can be operated to control the output shaft of the second electric cylinder 22 to retract, so that the angle between the bottom plate 21 and the support plate 20 becomes smaller, thereby driving the patient's head and neck to descend.

[0086] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
