The bionic lung breathing booster of the invention is further described by combining the following examples:
an axis perpendicular to the upper stage 14 is defined as a Z-axis perpendicular to the sliding pair P1Is set as the X-axis, while the axis perpendicular to the Z-axis and the X-axis is set as the Y-axis.
As shown in figure 1, the main mechanical structure of the bionic lung breathing booster machine utilizes the contraction and relaxation movement of the bionic lung breathing, the execution device adopts a 3-SPS-3U mechanism 4, the arrangement mode adopts a mode of opposite bottom supports at two sides, the power device adopts a worm and gear type motor for transmission, and the telescopic motor is utilized for mechanical reciprocating movement, so that the suction and the discharge of gas can be effectively guaranteed.
The 3-SPS-3U mechanism 4 has 4 degrees of freedom, and the structure can well meet the working requirement. Specifically three rotations and one movement, respectively rotation about axis X, Y, Z and movement along the Z-axis. When three sliding pairs P1、P2And P3When the synchronous movement is extended, the mechanism moves along the Z-axis direction, and the movement is the main movement and is the key of the mechanism for compressing the air bag 2; when P is present1、P2Two sliding pairs extending in translation, P3When the sliding pair moves and contracts, the upper platform 14 rotates around the X axis; when P is present2、P3Two sliding pairs extending in translation, P1When the sliding pair moves and contracts, the upper platform 14 rotates around the Y axis, and the motion around X, Y is redundant motion in the working condition, and the motion is not used generally; when moving pair P1、P2And P3The synchronous movement is contracted to a certain extent and the upper platform 14 is deflected and rotated around the Z-axis. The upper platform 14 of the 3-SPS-3U mechanism 4 is a serial part of the first platform block 55, the second platform block 65 and the third platform block 75, the local degree of freedom of the upper platform 14 does not influence the working requirement on compression of the air bag 2, the local degree of freedom is 2, specifically two rotations are adopted, the two rotations are respectively the local rotation around the X, Y shaft, the wrapping effect is achieved on the air bag, and the friction damage of the air bag is protected to a certain extent. I.e. when moving pair P1And a sliding pair P2And a sliding pair P3When the synchronous movement and the extension are started, the mechanism moves along the Z-axis direction, the closed-loop upper platform 14 connected in series through the first universal joint 13, the second universal joint 23 and the third universal joint 24 can generate a compression effect on the air bag 2, the upper platform 14 can generate a local degree of freedom according to the reaction force fed back by the air bag 2, and therefore the self-adaptive surface curve of the air bag 2 is attached to increase the contact area. The upper platform 14 can be well fitted to the surface curve of the airbag 2, so that the abrasion of the airbag 2 is reduced.
The contraction and relaxation of the balloon 2 mimics the breathing pattern of the human lungs. The lung respiration of a human body mainly utilizes the contraction and the relaxation of diaphragm muscles and intercostal muscles, so the 3-SPS-3U mechanisms 4 on the two sides of the air bag 2 imitate the motion mode of the intercostal muscles, and the 3-SPS-3U mechanism 4 at the bottom not only plays a role in supporting, but also imitates the motion mode of the diaphragm muscles. When the human body exhales, the air bag 2 starts to do diastole movement, and fresh and wet oxygen is inhaled into the air bag 2; when the human body inhales gas, the air bag 2 begins to do contraction movement to send oxygen into the human body, and the oxygen is sent to the lung of the human body one by one to supplement the lung of the human body, so that the storage capacity of the heart and lung is effectively saved.
The breathing booster can adjust three P in the 3-SPS-3U mechanism 4iThe stretching amount of (i is 1,2 and 3), so that the amplitude of stretching movement is controlled, the ventilation volume is further controlled, and the effect of performing progressive rehabilitation training on the user is achieved. In particular, three P's in the 3-SPS-3U mechanism 4i(i is 1,2,3) when the gas is driven by the worm-and-gear motor to fully extend, the air inflow reaches the maximum at the moment, and the maximum air inflow at the moment is defined as the oxygen amount required by the user for initially recovering the spontaneous respiration capacity; when the user gradually recovers the autonomous respiration ability, the adjustment should be performed according to the comfort of the user in real time. According to the recovery state of the user, the motor control system can be used for Pi(i-1, 2,3) is adjusted in real time, e.g. when the user feels dyspnea, P can be adjusted by the motor control systemiThe expansion and contraction amount of (i-1, 2,3) is slowly increased until the user feels comfortable to breathe; if the user feels that the inhaled oxygen is too much, the user can timely control the P through the motor control systemiThe amount of (i ═ 1,2,3) stretch is reduced, which would otherwise result in irreversible serious consequences such as lung injury.
The specific working steps of the invention based on the functions are as follows:
when the bionic lung breathing booster works, the bionic lung breathing booster is started and arranged on the moving pair P1And a sliding pair P2And a sliding pair P3The worm and gear type motor drives the three moving pairs to synchronously move to perform telescopic motion by controlling the motor, simulates the speed of air exhaled and inhaled from the lung of a normal person, compresses and releases the air bag 2, and performs mechanical reciprocating motion, so that the air bag 2 generates air inhaling and exhaling effects. Because the three 3-SPS-3U mechanisms 4 in the shell 1 are arranged in a mode of supporting the two opposite bottom ends, the worm gear type motor is used as a power device to drive the three moving pairs to synchronously moveWhen the air bag 2 is stretched, the air bag is contacted with the series closed loop type upper platform 14 of the three 3-SPS-3U mechanisms 4, and the two sides and the bottom end of the air bag are gradually increased under the pressure of the series closed loop type upper platform 14, so that the air bag 2 generates the effect of compressing the two sides and the bottom end, and the effect is the same as the effect generated by the contraction of the diaphragm muscle and the intercostal muscle during the lung breathing. The oxygen in the air bag 2 is pressed by the second oxygen tube 11 and enters the medical breathing mask 15 of the user. Since the check valve 30 is provided at the suction port of the tube of the medical breathing mask 15, the compressed oxygen is discharged from the suction port and does not return to the air bag 2, thereby smoothly feeding the oxygen into the lungs of the user. After the oxygen supplied to the lungs has been circulated, carbon dioxide and other gaseous waste products are exhaled from the user's mouth by the contraction of the diaphragm and intercostal muscles of the lungs, and the carbon dioxide and other gaseous waste products exhaled from the user's mouth are exhausted from the medical breathing mask 15 only through the exhaust port due to the check valve 30.
When oxygen is sent to the lungs of the user through the medical breathing mask 15, the air bag 2 is in a compressed state, so when the oxygen starts to discharge carbon dioxide and waste out of the body through a cycle in the lungs, the three moving pairs of the three 3-SPS-3U mechanisms 4 start to move synchronously and contract, the air bag 2 gradually reduces pressure due to the upper platform 14, and starts to expand slowly due to the elasticity of the air bag, the expanded air bag 2 sucks oxygen in the outside of the shell 1 into the air bag 2 through the first oxygen pipe 15 and the third oxygen pipe 19, and the oxygen sucked by the air bag 2 is treated through the air filtering device 6 and the humidifying device 7.
This bionical lung ventilator can make the user carry out the rehabilitation training with a mode that sequences, through the rational in infrastructure setting of device, effectively provides the gaseous exchange of timing ration.
The above-mentioned embodiments are merely illustrative of the preferred embodiments of the present invention, and do not limit the scope of the present invention, and various modifications and improvements made to the technical solution of the present invention by those skilled in the art without departing from the spirit of the present invention shall fall within the protection scope defined by the claims of the present invention.
