Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a respiratory device with synchronous oxygen supply. Background Art

[0002] Cardiopulmonary resuscitation mainly includes three steps: chest compression, opening the airway and artificial respiration. Among them, chest compression is an important link in helping patients restore spontaneous breathing and spontaneous circulation. Through chest compression, the patient's lungs can passively contract and expand, thereby assisting patients with cardiac and respiratory arrest to breathe. During chest compression, a higher concentration of oxygen needs to be delivered to the patient to increase the blood oxygen content and improve the blood oxygen diffusion capacity of the patient, so as to buy time for the subsequent restoration of spontaneous circulation.

[0003] In the prior art, a ventilator generally uses mechanical drive to pressurize gas with a high oxygen content into the lungs. When in use, the ventilator first selects a suitable ventilation mode according to the patient's specific situation, such as assisted controlled ventilation (A / C), synchronized intermittent mandatory ventilation (SIMV), etc., and provides a stable oxygen supply to the patient after wearing an oxygen mask.

[0004] During chest compression, the thorax is squeezed and the airway pressure increases, which may make it impossible to open the airway. At this time, if the ventilator performs ventilation, it is difficult for oxygen to enter the lungs through the airway, resulting in decreased blood oxygen saturation and carbon dioxide retention. In an emergency rescue environment, rescuers generally use manual chest compressions. The frequency of compressions is unstable, and it is difficult for the ventilator to cooperate with the rescuer's chest compression frequency, affecting the final oxygen supply effect.

[0051] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0052] like Figure 1 and Figure 2 As shown, the present invention provides a synchronous oxygen supply breathing device, comprising a vertical mounting plate 1, a telescopic frame 3 is movably mounted on one side of the vertical mounting plate 1, and a pressing pad 9 is mounted on the end of the telescopic frame 3;

[0053] A ventilation seat 2 and an oxygen supply pipe 4 are sequentially installed on the side of the vertical mounting plate 1 away from the telescopic frame 3 from top to bottom. The ventilation seat 2 is externally connected to an oxygen supply pipe 22, on which a solenoid valve 26 is installed, and an oxygen mask 6 is installed at the end of the oxygen supply pipe 22;

[0054] A folding airbag 29 is installed on the side of the vertical mounting plate 1 close to the telescopic frame 3, and the ventilation seat 2 and the oxygen supply pipe 4 are connected to the folding airbag 29. A rotating arm 5 is rotatably installed on the side of the vertical mounting plate 1 and at the bottom of the telescopic frame 3. One end of the folding airbag 29 is fixedly installed on the side of the vertical mounting plate 1, and the other end is installed on the rotating arm 5. The folding airbag 29 can be extended or contracted when driven by the rotation of the rotating arm 5.

[0055] A transmission member 7 is provided at the ends of the rotating arm 5 and the telescopic frame 3, and the transmission member 7 can make the rotating arm 5 and the telescopic frame 3 rotate in opposite directions or in opposite directions when the telescopic frame 3 rotates;

[0056] The telescopic frame 3 rotates toward the side close to the rotating arm 5 and drives the pressing pad 9 to press downward, the rotating arm 5 rotates toward the side close to the telescopic frame 3 and drives the folded airbag 29 to extend, the internal volume of the folded airbag 29 increases and forms a negative pressure to promote the gas in the oxygen supply pipe 4 to flow into the folded airbag 29, the telescopic frame 3 rotates toward the side away from the rotating arm 5 and drives the pressing pad 9 to move upward, the rotating arm 5 rotates toward the side away from the telescopic frame 3 and drives the folded airbag 29 to shrink, the internal volume of the folded airbag 29 decreases and forms a positive pressure to promote the gas in the folded airbag 29 to enter the oxygen mask 6 through the oxygen supply pipe 22 when the solenoid valve 26 is opened.

[0057] The compression pad 9 is aligned with the patient's chest, and the oxygen mask 6 is worn on the patient's mouth. When the solenoid valve 26 is closed, chest compression is performed on the patient only through the compression pad 9. At intervals, the solenoid valve 26 is opened. Only in the short period of time when the compression pad 9 follows the telescopic frame 3 away from the patient's chest, the folding airbag 29 is driven to shrink and positive pressure is formed inside the folding airbag 29 through the transmission member 7, so that the gas stored in the folding airbag 29 is input to the oxygen mask 6 through the oxygen supply tube 22 to complete ventilation. The integrated device can meet the ventilation and compression requirements at the same time. The interval design of ventilation and compression actions further avoids the situation where compression and ventilation are performed simultaneously to cause airway obstruction, thereby improving the oxygen supply effect and the rescue success rate.

[0058] During cardiopulmonary resuscitation, the ratio of compression frequency to ventilation frequency is usually 30:2. Therefore, the solenoid valve 26 needs to be opened at regular intervals to deliver the gas in the folded airbag 29 to the oxygen mask 6. The frequency of the solenoid valve 26 switching can be directly set here. According to the compression frequency of 100-120 times / minute, the ventilation frequency is 6-8 times / minute. That is to say, the solenoid valve 26 can be set to open once every 7-10 seconds. Only when the solenoid valve 26 is opened and the folded airbag 29 is compressed by the rotating arm 5, the oxygen in the folded airbag 29 can be delivered to the oxygen mask 6. When the solenoid valve 26 is closed, the rotating arm 5 compresses the folded airbag 29, and the oxygen in the folded airbag 29 will only be squeezed and not delivered to the oxygen mask 6.

[0059] From the perspective of the entire rescue process, the device of the present invention can simultaneously satisfy the actions of pressing and ventilation, while in the rescue process, pressing and ventilation must be performed asynchronously.

[0060] Since the rotating arm 5 and the telescopic frame 3 are installed on the same side of the vertical mounting plate 1, in order to cooperate with the transmission member 7 at its end for better transmission, a vertical plate 23 is installed on the side of the vertical mounting plate 1, and the end of the telescopic frame 3 is rotatably mounted on the vertical plate 23 through the first rotating shaft 701, and the end of the rotating arm 5 is rotatably mounted on the vertical plate 23 through the second rotating shaft 702;

[0061] The transmission member 7 can make the rotating arm 5 and the telescopic frame 3 rotate in opposite directions or in opposite directions when the telescopic frame 3 rotates. The transmission member 7 in the present invention adopts the following preferred embodiment, the transmission member 7 includes a driving gear 703 connected to the other end of the first rotating shaft 701 and a driven gear 704 connected to the other end of the second rotating shaft 702, and the driving gear 703 and the driven gear 704 are meshed with each other and installed on the vertical plate 23;

[0062] When the end of the telescopic frame 3 rotates around the first rotating shaft 701 , the driving gear 703 rotates accordingly and drives the driven gear 704 to rotate, so that the second rotating shaft 702 drives the rotating arm 5 to rotate.

[0063] In the present invention, the telescopic frame 3 and the rotating arm 5 can be regarded as necessary structures for establishing the association between the pressing action and the ventilation action. When the telescopic frame 3 rises, the rotating arm 5 falls, the pressing pad 9 rises, and the folded airbag 29 shrinks. In order to adapt to different individual patients, the position of the pressing pad 9 on the telescopic frame 3 is adjustable. Specifically, the telescopic frame 3 includes a long arm 301 and a telescopic arm 302.

[0064] A suspension rod 8 is installed at the end of the telescopic arm 302 away from the long arm 301, and a pressing pad 9 is installed at the other end of the suspension rod 8, wherein the telescopic arm 302 and the suspension rod 8 are rotatably connected via a first connecting shaft 31, and the suspension rod 8 and the pressing pad 9 are rotatably connected via a second connecting shaft 32;

[0065] When the rescuer performs chest compression on the patient, the rescuer adjusts the position of the telescopic arm 302 to adjust the position of the compression pad 9 relative to the patient, and places the compression pad 9 on the patient's chest. The rescuer presses the compression pad 9 to press the patient's chest 1.

[0066] On the one hand, the suspension rod 8 and the telescopic arm 302, as well as between the suspension rod 8 and the pressing pad 9 are all rotatably connected, so that during the up and down movement of the pressing pad 9, the horizontal displacement of the side connected to the pressing pad 9 when the long arm 301 swings as a whole can be compensated by tilting and sliding the telescopic arm 302. On the other hand, the pressing pad 9 can be folded and stored by cooperating with the telescopic arm 302 provided with the second storage slot 11.

[0067] like Figure 5 As shown, in order to facilitate storage of the entire device when not in use, a first storage groove 10 is provided in the long arm 301, and the telescopic arm 302 can slide in the first storage groove 10. A second storage groove 11 for accommodating the suspension rod 8 is provided on the telescopic arm 302, and a movable groove 27 is provided on the side wall of the second storage groove 11, and the first connecting shaft 31 can slide in the movable groove 27;

[0068] When storing, the suspension rod 8 is first rotated to a horizontal state with the first connecting shaft 31 as the center. Since the two corresponding side walls of the second storing groove 11 are provided with movable grooves 27 for the first connecting shaft 31 to slide, the suspension rod 8 is then pushed into the second storing groove 11 along the length direction of the telescopic arm 302, and finally the telescopic arm 302 is pushed into the first storing groove 10 along the length direction of the long arm 301; conversely, when it is needed to be used, the suspension rod 8 is first pulled out of the second storing groove 11 along the length direction of the telescopic arm 302, and then the telescopic arm 302 is pulled out of the first storing groove 10 along the length direction of the long arm 301, and finally the suspension rod 8 is rotated to a vertical state. In order to prevent the telescopic arm 302 from falling from the long arm 301 when the telescopic arm 302 is pulled out, a limit block can be installed at the end of the long arm 301 to prevent the telescopic arm 302 from continuing to be pulled out when the telescopic arm 302 is pulled to the end.

[0069] As the rescuer's hands rise and fall, the position of the compression pad 9 may be shifted. In order to ensure that the compression pad 9 can be close to the rescuer's hands during chest compression, lifting straps 24 for binding the rescuer's hands are provided on both sides of the compression pad 9.

[0070] The pressing action is completed by the rescuer manually in cooperation with the pressing pad 9. The pressing action in the present invention can be regarded as a driving action. Driven by the driving action, the telescopic frame 3 and the rotating arm 5 are both active, so that the folding airbag 29 is contracted under the action of lifting after pressing, so that the gas enters the oxygen mask 6 from the oxygen supply tube 22 to complete ventilation.

[0071] Since the ventilation seat 2 and the oxygen supply pipeline 4 are installed on the vertical mounting plate 1 facing the back side of the folding airbag 29, in order to connect the ventilation seat 2 and the oxygen supply pipeline 4 to the folding airbag 29, grooves are provided on the vertical mounting plate 1 facing the ventilation seat 2 and the oxygen supply pipeline 4, and the ventilation seat 2 and the oxygen supply pipeline 4 are connected to the inside of the folding airbag 29 through the grooves.

[0072] When the volume of the folding airbag 29 increases, the negative pressure can cause the oxygen in the oxygen supply pipe 4 to enter the folding airbag 29. When the folding airbag 29 is compressed, the positive pressure is likely to cause the oxygen in the folding airbag 29 to return to the oxygen supply pipe 4. To avoid such a situation, a one-way valve 28 is installed on the oxygen supply pipe 4. The function of the one-way valve 28 is to only allow oxygen to enter the folding airbag 29 from the oxygen supply pipe 4, and not allow the gas in the folding airbag 29 to flow back into the oxygen supply pipe 4.

[0073] like Figure 3 and Figure 4As shown, the pressing pad 9 drives the folding airbag 29 to contract and expand through the suspension rod 8, the telescopic arm 302, the long arm 301, the driving gear 703, the driven gear 704 and the rotating arm 5. The specific operation is as follows: when the pad 9 is pressed downward and the long arm 301 is driven to swing downward through the suspension rod 8 and the telescopic arm 302, the long arm 301 drives the driven gear 704 to rotate through the driving gear 703, so that the driven gear 704 drives the rotating arm 5 to swing away from the vertical mounting plate 1, thereby pulling the folding airbag 29 to expand; conversely, when the rescuer's hand moves upward to reset and through the lifting belt 2 When the pressing pad 9 is driven to move upward, the long arm 301 swings upward and the rotating arm 5 swings toward the direction close to the vertical mounting plate 1, so that the folded airbag 29 is compressed to correspond to the patient's inhalation when the chest cavity expands. The long arm 301 is connected to the shorter rotating arm 5 through the driving gear 703 and the driven gear 704, which is similar to a lever mechanism, that is, the length of the power arm is much greater than that of the resistance arm, so that the rescuer can easily drive the long arm 301 to swing back and forth through the pressing pad 9, and transmit the power through the driving gear 703 and the driven gear 704 to realize the reciprocating swing of the rotating arm 5.

[0074] The telescopic frame 3 drives the folding airbag 29 to expand and contract to perform intermittent positive pressure oxygen supply. The amount of air inhaled by an adult each time is about 250 ml, and the volume inside the folding airbag 29 does not need to be less than the amount of air inhaled by an adult each time. Therefore, the volume of the folding airbag 29 is also small. A portable oxygen bag and oxygen tank are used at the end of the oxygen supply pipe 4, so that the device has the advantages of simple structure, low cost, and easy carrying and transfer, which is conducive to the large-scale deployment and rapid deployment of the device, so as to be suitable for emergency scenarios.

[0075] The integrated device provided by the present invention mainly converts the driving action of pressing into the driving force of ventilation. It is suitable for situations where there is no intelligent ventilator in actual emergency rescue. A simple oxygen cylinder is connected to the oxygen supply pipe 4 to realize manual-driven ventilation and pressing, and ventilation and pressing can be avoided to be carried out simultaneously under the premise of realizing ventilation and pressing.

[0076] Since the weights on both sides of the vertical mounting plate 1 are inconsistent, it is difficult to maintain balance during cardiopulmonary resuscitation. In order to enable the vertical mounting plate 1 to remain stable during cardiopulmonary resuscitation, the present invention is designed to fix the vertical mounting plate 1 on a support through a support column 12. Specifically, support columns 12 are connected to both sides of the bottom of the vertical mounting plate 1, and a fixed claw 13 is fixedly installed on the support column 12. A movable claw 14 is slidably installed on the support column 12 at the bottom of the fixed claw 13. A thread is provided on the outer wall of the support column 12, and a nut 25 matching the thread is provided on the support column 12. The movable claw 14 is supported on the nut 25. By turning the nut 25 to make a spiral motion on the support column 12, the movable claw 14 is driven to move and gradually approach or move away from the fixed claw 13.

[0077] The specific operation is that after the fixed claw 13 is supported on a supporting object such as the edge of a bed frame, the nut 25 is rotated to make the nut 25 and the movable claw 14 move upward together, until the movable claw 14 and the fixed claw 13 firmly clamp the supporting object, thereby achieving fixed installation of the entire device.

[0078] Among them, the vertical mounting plate 1 is provided with sockets 15 on both sides near the bottom, and a plurality of pin holes 17 are vertically spaced on the support column 12. The sockets 15 are directly opposite to the pin holes 17 at the same horizontal height, and are inserted and matched by the pins 16. That is to say, the vertical mounting plate 1 is fixed to the support column 12 by the pins 16. At the same time, in order to be suitable for patients with different chest heights, the sockets 15 can be matched with pin holes 17 at different heights on the support column 12 to adjust the height position of the vertical mounting plate 1 relative to the support column 12, thereby adjusting the height of the pressing pad 9.

[0079] Since the end of the long arm 301 close to the vertical mounting plate 1 is connected to the driving gear 703, after the telescopic arm 302 is retracted into the first storage slot 10, the long arm 301 is rotated upward to a vertical position through the driving gear 703. At this time, the rotating arm 5 is driven by the driven gear 704 to rotate downward to a vertical position and compress the folded airbag 29, which is not only conducive to protecting the folded airbag 29, but also can avoid the protruding long arm 301 and the rotating arm 5 from causing inconvenience to the storage of the device. After storage, In order to prevent the long arm 301 from rotating downward under the action of gravity when the device shakes, guard plates 18 are vertically arranged on both sides of the vertical mounting plate 1, and a check plate 19 is vertically slidably arranged between the guard plates 18 on both sides. The check plate 19 is located above the driving gear 703, and a slide groove 20 is vertically arranged on the guard plates 18 on both sides. A damping slider 21 is slidably arranged in the slide groove 20. Both ends of the check plate 19 are connected to the damping slider 21, and the check plate 19 is slidably arranged between the guard plates 18 through the damping slider 21;

[0080] After the telescopic frame 3 rotates to between the guard plates 18 , the check plate 19 slides downward to the outer side of the telescopic frame 3 away from the vertical mounting plate 1 , so that the telescopic frame 3 is limited between the guard plates 18 .

[0081] In addition, in order to prevent the long arm 301 from continuing to rotate downward after rotating to the horizontal position during chest compression, thereby causing damage due to multiple collisions with the rotating arm 5, a blocking block is installed between the long arm 301 and the rotating arm 5 on the vertical plate 23. The blocking block can limit the long arm 301 so that the long arm 301 cannot continue to rotate offline when it rotates to the horizontal position.

[0082] When performing chest compression, the pressing depth for adults is 5 to 6 cm, the pressing depth for children is about 5 cm, and the pressing depth for infants is about 4 cm. Therefore, when the long arm 301 is in a horizontal position, the pressing depth of the pressing pad 9 can reach a maximum of 6 cm.

[0083] The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
