Description

Technical Field

[0002] Respiratory failure refers to a clinical syndrome in which the ventilation or gas exchange function of the lungs is seriously impaired due to some reasons, affecting the effective exchange of gases between the lungs and the outside world, causing hypoxia or hypoxia accompanied by carbon dioxide retention, and a series of physiological function and metabolic disorders. As an effective means of artificially replacing the spontaneous ventilation function, the ventilator is a device that can replace, control or change normal physiological breathing, increase lung ventilation, improve respiratory function, reduce respiratory work consumption, and save cardiac reserve capacity. It has been widely used in respiratory failure caused by various reasons, anesthesia respiratory management during major surgery, respiratory support therapy, and emergency resuscitation, and occupies a very important position in the field of modern medicine. The ventilator is a vital medical device that can prevent and treat respiratory failure, save and prolong the life of patients.

Although some home ventilators can assist breathing, their functions are only active oxygen supply and ventilation. Generally, the gas supply volume and frequency are relatively fixed. However, since the patient's physical condition may change at different times, traditional home ventilators cannot flexibly adjust the inflation volume and inflation frequency according to the patient's actual breathing situation, and cannot effectively assist people with unstable physical conditions to breathe fully, which is not conducive to the patient's recovery.

[0017] The present invention has the following advantages: during actual use, the operator wears the mask on the patient's face and places the air outlet in the patient's respiratory tract. If the patient's physical condition changes and respiratory failure occurs, it will become very difficult for him to inhale and exhale, so the total amount of gas exhaled within a certain period of time will decrease. During operation, when the piston block moves downward, the amount of gas entering the detection cylinder from the exhalation tube will decrease. When the suction volume of the detection cylinder remains unchanged, if the detection cylinder is not filled with enough gas, negative pressure will be generated in the detection cylinder. Since the valve box is connected to the detection cylinder, the valve stem in the valve box will move toward the direction close to the detection cylinder, and the valve port on the valve stem corresponds to the air guide port. At this time, the air supply pump is connected to the first air guide tube and supplies air to the inside of the piston column. The shunt slot is filled with gas. In the initial state, the regulating block in the regulating cylinder is located below the connection between the ventilating pipe and the regulating cylinder. Therefore, when the gas in the shunt slot enters the regulating cylinder through the ventilating pipe, the pressure in the regulating cylinder increases, the regulating block will move downward, and drive the push plate on the support column to move downward. Then, when the support block follows the piston column to make up and down piston movements, when the support block moves down to the lowest position, the push plate is also in the lowest position. Compared with the initial state, this position is located at a lower position of the pump cylinder. Therefore, the effective suction volume in the pump cylinder is increased, which makes the suction and pumping volume larger each time, increases the amount of gas filled into the patient's body each time, assists the patient to take a deeper breath, and relieves the patient's lack of breathing. If the patient does not return to normal Instead, the breathing becomes slower and slower, and the amount of exhaled air drawn into the detection cylinder each time per unit time will be less, and the negative pressure generated will be greater, so that the valve stem will continue to move toward one side of the detection cylinder, and the valve port on the valve stem is connected with all the air guide ports. At the same time, an air supply pump is added to supply air. At this time, the second air guide pipe is connected with the air supply pump, and the air supply pump supplies air to the sleeve through the second air guide pipe, and the gas enters the corresponding mounting cylinder through the diversion ports on the rotating cylinder. The pressure increase in the mounting cylinder will drive the adjusting column on the piston block to move upward, and the adjusting column drives the arc plate to move to the side away from the mounting cylinder, then the distance between the rotating cylinder and the arc plate becomes larger, and the rotation diameter of the arc plate becomes larger. Since the arc plate and the transmission wheel below are driven by a belt, when the rotating cylinder drives the arc plate to rotate one circle It can drive the transmission wheel to rotate more circles, and then drive the push plate in the pump cylinder to move up and down more frequently through the traditional arm, thereby increasing the pumping frequency and replenishing air for the patient in a faster manner. As the pumping progresses, if the patient resumes normal breathing, the volume of exhaled gas inhaled in the detection cylinder per unit time will increase to a normal state, and then no negative pressure will be generated in the detection cylinder, and the valve stem will be reset. If it does not return to normal, or is in a more exhausted state, the valve stem will continue to move toward the side close to the detection cylinder. At this time, the alarm rod at the end of the valve stem will extend from the warning cylinder, indicating that the patient's body is in an extremely dangerous situation and requires manual rescue measures. In the above process, the device can detect the patient's breathing status while assisting the patient's breathing.According to the amount of gas exhaled by the patient per unit time, it is judged whether the breathing condition meets the health standard, and then the pumping volume and pumping frequency are automatically adjusted according to the detection results to improve the effect of assisted breathing, which is more conducive to the recovery of patients in unstable physical conditions. The operation is flexible and convenient, and the safety is higher. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] See also Figure 1-Figure 10 As another embodiment of the present invention, a touch computer 36 is provided on the side wall of the enclosure 8 above the purification box 35 for displaying the patient's respiratory rate and ventilator auxiliary data, and intelligently regulating the humidity and temperature of the pumped air through the control box 34 to make the patient breathe more comfortably.

[0044] During the implementation of the present invention, the operator wears the mask 10 on the patient's face. The mask 10 only covers the area below the nasal cavity including the mouth. The nasal cavity is outside the mask 10. The inhalation tube 11 connected to the air outlet head 9 is close to the contact position between the mask 10 and the skin and extends from the mask 10. The air outlet head 9 is made of a hose material. Then the air outlet head 9 is placed in the patient's nasal cavity. The inhalation tube 11, the mask 10 and the skin contact position are sealed with medical tape. A sealing pad can be set on the contact surface between the mask 10 and the skin. Under this condition, the mask 10 is sealed with the face. When the gas is pumped out, only the gas exhaled by the patient is pumped in. The air outlet head 9 is placed in the patient's respiratory tract, and then the drive motor 33 and the arc plate 4 are started. 7 rotates, and multiple arc plates 47 drive the transmission wheel 21 to rotate through belt transmission. The transmission wheel 21 drives the transmission arm 20 below the pump cylinder 24 to rotate. Under the action of the transmission arm 20, the transmission rod 13 can drive the piston column 18 above the transmission frame 19 to move back and forth up and down. The piston column 18 drives the push plate 44 to move back and forth up and down in the pump cylinder 24. When the push plate 44 rises, since a one-way valve is provided at the end of the suction pipe 11, using this valve, the gas can only flow from the suction pipe 11 to the gas outlet head 9, and cannot flow in the opposite direction. Therefore, when the push plate 44 moves downward, only the outside air filtered by the filter box 5 can be drawn into the pump cylinder 24 through the intake pipe 6. When the push plate 44 rises, , because the air intake pipe 6 and the pump drive the rotating cylinder 29 to rotate, the rotating cylinder 29 drives the installation cylinder 32 to revolve, and then drives the connection of the air cylinder 24 on the adjusting column 48 on one side of the installation cylinder 32 to be provided with a one-way valve. With this valve, the gas can only flow into the pump air cylinder 24 from the air intake pipe 6, and cannot flow in the opposite direction. Therefore, when the air push plate 44 rises, the gas can only be sent into the patient's body through the suction pipe 11 to achieve the function of auxiliary suction; at the same time, the rotating cylinder 29 drives the transmission arm 20 below the detection cylinder 28 to rotate through the belt, and under the action of the transmission arm 20, the transmission rod 13 can drive the piston rod 22 above the transmission frame 19 to move back and forth up and down, thereby driving the piston block 41 to move back and forth up and down, and the piston block 41 When the piston block 41 moves downward, the gas exhaled by the patient enters the detection cylinder 28 through the exhalation tube 12. In this process, a one-way valve is provided at the connection between the exhaust pipe 14 and the detection cylinder 28. With this valve, the gas can only enter the exhaust pipe 14 from the detection cylinder 28 and cannot flow in the reverse direction. Therefore, the gas inhaled into the detection cylinder 28 is all the gas exhaled by the patient. When the piston block 41 moves upward, the gas is discharged from the exhaust pipe 14 into the purification box 35. A one-way valve is provided at the connection between the exhalation pipe 12 and the detection cylinder 28. With this valve, the gas can only enter the detection cylinder 28 from the exhalation pipe 12 and cannot flow in the reverse direction. Therefore, all the gas is discharged from the exhaust pipe 14. The above process achieves the effect of assisting the patient's breathing.

[0045] During the assisted breathing process, if the patient's physical condition changes and respiratory failure occurs, it will become very difficult for the patient to inhale and exhale. Therefore, the total amount of gas exhaled within a certain period of time will decrease. At this time, during the downward movement of the piston block 41, the amount of gas entering the detection cylinder 28 from the expiratory tube 12 will decrease. When the suction volume of the detection cylinder 28 remains unchanged, if there is not enough gas in the detection cylinder 28, negative pressure will be generated in the detection cylinder 28. Since the valve box 37 is connected to the detection cylinder 28, the valve stem 39 in the valve box 37 will move toward the detection cylinder 28, and the valve port 45 on the valve stem 39 corresponds to the air guide port 58. At this time, the air supply pump 42 is connected to the first air guide tube 27, and fills the diverter groove 55 inside the piston column 18 with gas. In the initial state, the regulating block 52 in the regulating cylinder 46 is located below the connection between the vent pipe 57 and the regulating cylinder 46. Therefore, when the gas in the shunt groove 55 enters the regulating cylinder 46 through the vent pipe 57, the pressure in the regulating cylinder 46 increases, the regulating block 52 will move downward, and drive the push plate 44 on the support column 53 to move downward. When the support block 43 follows the piston column 18 to make an up and down piston movement, when the support block 43 moves down to the lowest position, the push plate 44 is also in the lowest position. Compared with the initial state, this position is located at a lower position of the pump cylinder 24. Therefore, the effective suction volume in the pump cylinder 24 is increased, so that the suction and pumping volume are larger each time, which increases the amount of gas filled into the patient's body each time, and assists the patient to do deeper Breathing to relieve the patient's breathing shortage. In this state, if the patient's breathing condition improves, the volume of exhaled gas inhaled into the detection tube 28 per unit time will increase to a normal state, and then the negative pressure will not be regenerated in the detection tube 28, and the valve stem 39 will be reset, and the single pumping volume will no longer be increased. If the patient does not return to normal but breathes more and more slowly, the exhaled volume drawn into the detection tube 28 each time per unit time will be less, and the negative pressure generated will be greater, and then the valve stem 39 will continue to move to the side of the detection tube 28, and the valve port 45 on the valve stem 39 is connected to all the air guide ports 58, and an air supply pump 42 is added to supply air. At this time, the second air guide tube 31 is connected to the air supply pump 42, and the air supply pump 42 supplies air to the sleeve through the second air guide tube 31 30, the gas enters the corresponding installation cylinder 32 through the diversion port 49 on the rotating cylinder 29. The pressure increase in the installation cylinder 32 will drive the adjusting column 48 on the piston block 41 to move upward, and the adjusting column 48 drives the arc plate 47 to move away from the installation cylinder 32. Then, the distance between the rotating cylinder 29 and the arc plate 47 becomes larger, and the rotation diameter of the arc plate 47 becomes larger. Since the arc plate 47 and the transmission wheel 21 below are driven by a belt, when the rotating cylinder 29 drives the arc plate 47 to rotate one circle, it can drive the transmission wheel 21 to rotate more circles, and then the push plate 44 in the pump cylinder 24 can be driven by the traditional arm to move up and down more frequently, thereby increasing the pumping frequency and replenishing the patient with gas in a faster way. As the pumping progresses, if the patient resumes normal breathing,Then the volume of exhaled gas inhaled into the detection tube 28 per unit time will increase to the normal state, and then the detection tube 28 will not generate negative pressure, and the valve stem 39 will reset. If it does not return to normal, or is in a more exhausted state, the valve stem 39 will continue to move to the side close to the detection tube 28. At this time, the alarm rod 38 at the end of the valve stem 39 will extend from the warning tube 25, indicating that the patient's body is in an extremely dangerous situation and requires manual rescue measures. In the above process, the device can detect the patient's breathing state while assisting the patient's breathing. According to the amount of gas exhaled by the patient per unit time, it can determine whether the breathing condition meets the health standard, and then automatically adjust the pumping volume and pumping frequency according to the detection situation, so as to improve the effect of assisted breathing, which is more conducive to the recovery of patients in unstable physical conditions. The operation is flexible and convenient, and the safety is higher.
