Example 1
As shown in fig. 1, the device comprises a breathing mask 1 made of common medical grade plastic, and the contact part between the contour edge and the human body is made of soft material, so as to seal gas when the breathing mask is attached to the face. The breathing mask 1 is connected with the inflator 4 through the connector 2, the connector 2 can rotate, and the proper position is adjusted according to the needs in use. The inner cavity of the inflator 4 is provided with a interlayer which divides the inner cavity into two independent air chambers, and each air chamber is respectively provided with two one-way valves at the positions of the cylinder wall and the joint 2, and the opening and closing of the one-way valves can be regulated by the internal and external pressure difference so as to control the air flow direction. The piston assembly 5 is provided with two independent pistons corresponding to the two air chambers of the air cylinder 4, and is movably connected and sealed with the two air chambers of the air cylinder 4 respectively.
As shown in fig. 2, the outer wall of the air cylinder 4 is provided with a first check valve 31 and a second check valve 32 corresponding to the two air chambers, respectively, which control the air exchange between the air cylinder 4 and the atmosphere. A third one-way valve 33 and a fourth one-way valve 34 are arranged between the connector 2 and the inflator 4, and are relatively independent to each other, so as to control the gas exchange between the respiratory tract of the human body and the inflator 4. In the reciprocating motion process of the piston, the opening and closing of each one-way valve are controlled by the pressure difference among the human respiratory tract, the air chamber in the air cylinder 4 and the atmosphere, so that the flow direction of the air is controlled.
As shown in fig. 3, the piston assembly 5 moves to the right, the pressure in the air cylinder 4 is lower than the respiratory tract pressure and the atmospheric pressure of the human body, the first check valve 31 is closed, the second check valve 32 is opened, the third check valve 33 is opened, and the fourth check valve 34 is closed. The air in the respiratory tract of the human body enters the first air chamber through the first one-way valve 31, and the fresh air in the atmosphere enters the second air chamber through the second one-way valve 32 to assist in completing the exhalation action of the human body. At this time, the first air chamber stores "waste air" in the respiratory tract of the human body, and the second air chamber stores fresh air in the atmosphere.
As shown in fig. 4, the piston assembly 5 moves to the left, the pressure in the air cylinder 4 is higher than the respiratory tract pressure and the atmospheric pressure of the human body, the first check valve 31 is opened, the second check valve 32 is closed, the third check valve 33 is closed, and the fourth check valve 34 is opened. The waste gas in the first air chamber is discharged to the atmosphere through the first one-way valve 31, and the fresh air in the second air chamber enters the respiratory tract of the human body through the fourth one-way valve 34 to assist in completing the inhalation action of the human body.
The device is independent of the gas breathed by the human body through the two independent air chambers, avoids the condition that the breathing gas of the traditional air bag is disordered into the mixed gas of the breathed waste gas and the air, and breathes out the gas for the second time, thereby rapidly improving the breathing condition, improving the oxygen content in the air and improving the oxygenation efficiency of the human body. Meanwhile, the air inlet and outlet amount can be controlled through the formation of the movement of the piston, and the accurate control of the auxiliary air inlet amount is realized. Because the volumes of the double air chambers are the same, the movement strokes of the pistons are consistent, so that the air inflow and the air outflow of each cycle are consistent, safe and effective auxiliary respiration is realized, and the respiration condition of a patient is improved.
Example two
As shown in fig. 5, in order to cope with possible pathogenic viruses transmitted through the respiratory tract, and combine epidemic prevention and protection for the rescuer, in this embodiment, a water-proof and breathable film 6 is added between the first check valve 31 and the third check valve 33 of the first air chamber on the basis of the first embodiment, so that the harmful substances such as viruses in the "waste gas" exhaled by the human body can be effectively filtered, and the safety of the rescuer and the nursing staff is protected. Further, the chlorine-containing sterilizing solution is wrapped in the water-proof breathable film 6 in the first air chamber to purify the waste air exhaled by the human body and then discharged to the atmosphere.
The device assists human body breathing action by means of the combination of the simple piston inflator 4 and the one-way valve, achieves that waste gas is independent of fresh air, replaces traditional auxiliary breathing air bags and mouth-to-mouth artificial respiration, provides a safe and effective auxiliary breathing device for a rescuer, simultaneously provides a self-protection safety barrier for the rescuer, reduces infection risk of the rescuer, and relieves worry of the back-consultant.
Example III
As shown in fig. 6 to 7, on the basis of the structure of embodiment 1, a limit groove is formed on the piston push rod and a limit device 7 is additionally arranged, and the function of the limit groove is to increase the anchor point of the limit device 7 and fix the limit device 7. The limiting device 7 can adjust the position on the piston push rod to limit the compression displacement distance of the piston assembly 5 each time, so as to limit the air quantity injected into the lung of the human body by single movement of the device. Because different individual lung capacity differences are different, the excessive gas gets into the lung in the rescue process and probably causes the injury to the human body, so this device has increased relief valve 8 on the basis of above-mentioned embodiment in joint department, and it can open under the too big condition of bolus pressure, outwards exhaust, avoids the excessive or too big gas of pressure to get into human respiratory tract in the bolus process, damages the lung. In the embodiment, through the adjustable limiting device 7 and the safety valve 8, excessive gas or gas with excessive pressure in the rescue process is prevented from entering the lung of a human body, and other injuries are avoided as much as possible while the rescue effect is ensured.
As shown in fig. 8-9, the limiting device 7 is composed of a limiting stop 71 and a locking plate 72, wherein a through slot is arranged in the middle of the limiting stop 71, the locking plate 72 can slide in the slot, and the locking plate 72 is provided with a notch which can limit the pushing stroke of the piston assembly 5. When the lock plate 72 is in the state shown in fig. 9, the limiting device 7 can be moved and adjusted up and down, and after the lock plate 72 is adjusted to a proper position, the lock plate 72 is pushed to enable the notch of the lock plate 72 to be dislocated with the piston push rod, and the lock plate 72 is clamped into the limiting groove on the piston push rod, so that the movement of the limiting device 7 is limited. In the use process, the piston assembly 5 is pushed, and when the limiting device 7 contacts the air cylinder 4, the piston assembly 5 cannot be pushed continuously, so that excessive gas is prevented from being pushed into the respiratory tract of a human body.
The safety valve 8 and the limiting device 7 are additionally arranged on the basis of the basic functions of the original device, so that excessive gas or gas with excessive pressure in the using process is prevented from being injected into the respiratory tract of a human body to damage the human body. The maximum gas amount of single bolus injection is limited by adding the adjustable limiting device 7, so that the human body damage possibly brought in the rescue process is protected.
