本发明涉及呼吸器技术领域，具体涉及一种简易呼吸器。The present invention relates to the technical field of respirators, in particular to a simple respirator.
背景技术Background Art
简易呼吸器又称为加压给氧气囊，是维持人工通气最简单的急救装置，具有便携和使用方便，有无氧源均可通气的优点，常用于现场急救、院内重症患者转运等重要场合，简易呼吸器分别由面罩、单向阀(鸭嘴阀)、呼气阀、压力安全阀、球体/气囊、进气阀、储气阀、储氧安全阀、储氧袋、氧气连接口十个部件结构组成；当操作者挤压气囊时，气囊内的气体经单向阀，通过面罩或气管插管进入患者的呼吸道，为呼吸功能障碍的患者供氧，起到人工呼吸的作用，能有效改善患者呼吸功能。The simple respirator, also known as a pressurized oxygen bag, is the simplest first aid device for maintaining artificial ventilation. It is portable and easy to use, and can be used for ventilation with or without an oxygen source. It is often used in important occasions such as on-site first aid and transfer of critically ill patients in hospitals. The simple respirator consists of ten components: a mask, a one-way valve (duckbill valve), an exhalation valve, a pressure safety valve, a ball/airbag, an air inlet valve, an air storage valve, an oxygen storage safety valve, an oxygen storage bag, and an oxygen connection port. When the operator squeezes the airbag, the gas in the airbag passes through the one-way valve, through the mask or endotracheal tube, into the patient's respiratory tract, supplying oxygen to patients with respiratory dysfunction, playing the role of artificial respiration, and effectively improving the patient's respiratory function.
根据《简易呼吸器专用要求》标准规定，简易呼吸器有婴儿、儿童、成人三种类型，气囊容积分别约为280ml、500ml、1500ml，不同年龄组间在潮气量、频率及气道压力均有较大差异：成人＞600ml，10-12次/分，压力＜60cmH20；婴幼儿潮气量大小为15ml/kg，频率儿童16-20次/分，婴儿35次/分，压力＜40cmH20。According to the standard "Special Requirements for Simple Respirators", there are three types of simple respirators: for infants, children and adults. The air bag volumes are approximately 280ml, 500ml and 1500ml respectively. There are large differences in tidal volume, frequency and airway pressure among different age groups: for adults > 600ml, 10-12 times/min, and pressure < 60cmH20; the tidal volume for infants is 15ml/kg, the frequency for children is 16-20 times/min, for infants is 35 times/min, and the pressure is < 40cmH20.
由于成人和儿童的给气量不同，现有的简易呼吸器一般会分别配置不同的气囊和面罩，同时需要医护人员采取不同的按压气囊的频率与力度，在进行院前急救时，如未能明确病人情况或在大型事故伤患较多的情况，需要同时配备有成人与儿童简易呼吸器，一方面可能会出现装置未配备齐全的情况，延误抢救时机，危及患者生命，其次增加了医护人员工作量和工作难度，为此提出一种简易呼吸器。Since the air supply volume for adults and children is different, the existing simple respirators are generally equipped with different air bags and masks respectively, and medical staff are required to press the air bags at different frequencies and strengths. When performing pre-hospital emergency treatment, if the patient's condition is not clear or there are many casualties in a large accident, it is necessary to equip both adult and child simple respirators. On the one hand, the devices may not be fully equipped, delaying the rescue time and endangering the patient's life. On the other hand, it increases the workload and difficulty of the medical staff. Therefore, a simple respirator is proposed.

本发明的有益效果如下：The beneficial effects of the present invention are as follows:
1、本发明通过设置两个给气球囊，在使用时，可以按压对应的给气球囊，辅助患者呼吸，由于两个给气球囊以及配对的压力阀、控制阀等阀门组件的规格不同，使两个给气球囊每次的输气量分别可以对应成人与儿童的给气量，将原先不同规格的呼吸器统合成同一个呼吸器中，有效规避抢救过程中呼吸器配备不全的风险；1. The present invention provides two air supply balloons. When in use, the corresponding air supply balloon can be pressed to assist the patient's breathing. Since the two air supply balloons and the matching pressure valves, control valves and other valve components have different specifications, the air delivery volume of the two air supply balloons can correspond to the air supply volume of adults and children respectively, integrating the original respirators of different specifications into the same respirator, effectively avoiding the risk of incomplete respirator equipment during the rescue process;
2、本发明通过设置面罩组件，使得在面对成年患者时，可以使内圈气囊罩和外圈气囊罩鼓起形成碗状面罩，而在面对儿童患者时，将连通管从接口处拔出，使外圈气囊罩折叠在内圈气囊罩顶部，将内圈气囊罩单独作为面罩使用，缩小面罩体积，使该面罩组件可以根据患者的年龄而对外形和规格进行更改；2. The present invention provides a mask assembly so that when facing an adult patient, the inner circle airbag cover and the outer circle airbag cover can be inflated to form a bowl-shaped mask, and when facing a child patient, the connecting tube is pulled out from the interface, the outer circle airbag cover is folded on the top of the inner circle airbag cover, and the inner circle airbag cover is used alone as a mask, which reduces the volume of the mask, so that the mask assembly can be changed in shape and specifications according to the age of the patient;
3、本发明通过设置塑性条，使得在面罩组件充气展开后，通过折弯多个塑性条以及第一塑形环、第二塑形环，来使内圈气囊罩和外圈气囊罩可以调整成需要的形状，使内圈气囊罩和外圈气囊罩(或单独的内圈气囊罩)可以更加贴合患者面型，减少面罩与患者面部接缝处的气体泄漏，保证该呼吸器的正常使用；3. The present invention provides a plastic strip so that after the mask assembly is inflated and unfolded, the inner ring airbag cover and the outer ring airbag cover can be adjusted to a desired shape by bending a plurality of plastic strips and the first shaping ring and the second shaping ring, so that the inner ring airbag cover and the outer ring airbag cover (or a separate inner ring airbag cover) can better fit the patient's face shape, reduce gas leakage at the seam between the mask and the patient's face, and ensure the normal use of the respirator;
4、本发明通过设置推气压板，使得在需要按压给气球囊时，可以旋转悬挂架使两个推气压板同步平行移动至给气球囊的顶部和底部，然后两个微型电动推杆分别驱动两个推气压板上下移动，对给气球囊进行机械式按压，代替人工手动按压，不仅可以提高输气量的精准控制，还可以减少医护人员的疲劳强度；4. The present invention sets a push air pressure plate, so that when it is necessary to press the gas supply balloon, the suspension frame can be rotated to make the two push air pressure plates move synchronously and parallel to the top and bottom of the gas supply balloon, and then the two micro electric push rods drive the two push air pressure plates to move up and down respectively, and the gas supply balloon is mechanically pressed instead of manual pressing, which can not only improve the precise control of gas delivery, but also reduce the fatigue intensity of medical staff;
5、本发明通过设置调频开关，使得在推气压板分别向两侧的给气球囊移动时，两个磁性块会与其中一侧的侧边磁吸板和调频开关接触，从而被侧边磁吸板吸附固定，有效避免推气压板产生滑移，影响输气量控制的精准度，同时会触发该处的调频开关，调整当前推气压板的按压频率与按压深度，实现给气量的调整与控制；5. The present invention sets a frequency modulation switch so that when the air pressure plate moves toward the air supply balloons on both sides, the two magnetic blocks will contact the side magnetic suction plate and the frequency modulation switch on one side, so as to be adsorbed and fixed by the side magnetic suction plate, effectively avoiding the air pressure plate from slipping and affecting the accuracy of air supply control. At the same time, the frequency modulation switch there will be triggered to adjust the pressing frequency and pressing depth of the current air pressure plate, so as to adjust and control the air supply;
6、本发明通过设置正向磁吸板，使得将推气压板转至两个给气球囊之间的位置，然后两个微型电动推杆带动推气压板与两个正向磁吸板接触，从而被正向磁吸板吸附固定，进而防止两个推气压板发生晃动，方便收纳，同时可在固定后推气压板后，方便医护人员手动按压给气球囊，满足该呼吸器的多种使用需求；6. The present invention sets a positive magnetic suction plate to rotate the air pressure plate to the position between the two air supply balloons, and then the two micro electric push rods drive the air pressure plate to contact the two positive magnetic suction plates, so that the air pressure plate is adsorbed and fixed by the positive magnetic suction plates, thereby preventing the two air pressure plates from shaking, making it convenient to store. At the same time, after the air pressure plate is fixed, it is convenient for medical staff to manually press the air supply balloon, meeting the various use requirements of the respirator;
7、本发明通过设置吹嘴，使得在急救现场没有充气工具时，可将吹气管一侧的吹嘴取下并塞入吹气管一端内，使吹嘴与吹气管对接，然后由医护人员经吹嘴和吹气管向内圈气囊罩和外圈气囊罩内部吹气，实现外圈魔术贴和外圈气囊罩的紧急充气，避免对急救工作造成影响；7. The present invention provides a mouthpiece so that when there is no inflation tool at the emergency scene, the mouthpiece on one side of the air blowing tube can be removed and inserted into one end of the air blowing tube, so that the mouthpiece and the air blowing tube are connected, and then the medical staff blows air into the inner circle airbag cover and the outer circle airbag cover through the mouthpiece and the air blowing tube to achieve emergency inflation of the outer circle Velcro and the outer circle airbag cover, thereby avoiding affecting the emergency work;
8、本发明通过设置内圈魔术贴和外圈魔术贴，使得在将面罩组件由成人规格替换为儿童规格时，可将干瘪的外圈气囊罩折叠在内圈气囊罩顶部，并使内圈魔术贴与外圈魔术贴对接相互粘黏，对外圈气囊罩进行固定，避免对面罩组件的正常使用造成影响；8. The present invention provides inner and outer Velcros, so that when the mask assembly is replaced from adult specifications to children specifications, the deflated outer airbag cover can be folded on top of the inner airbag cover, and the inner Velcro and the outer Velcro are butted and adhered to each other to fix the outer airbag cover, thereby avoiding affecting the normal use of the mask assembly;
9、本发明通过设置松紧套绳，使得松紧套绳可以套接在患者的头部，使塑形后的面罩组件可以在松紧套绳的弹性作用下紧密贴合患者面部，同时在外圈气囊罩折叠固定在内圈气囊罩上后，松紧套绳的两端会有一部分也被折叠在内圈气囊罩的顶部，进而缩短松紧套绳的长度，使松紧套绳的长度可以更加适配儿童的头型。9. The present invention provides an elastic loop so that the elastic loop can be sleeved on the patient's head, so that the shaped mask assembly can fit the patient's face closely under the elastic action of the elastic loop. At the same time, after the outer ring airbag cover is folded and fixed on the inner ring airbag cover, parts of the two ends of the elastic loop will also be folded on the top of the inner ring airbag cover, thereby shortening the length of the elastic loop and making the length of the elastic loop more suitable for the child's head shape.

如图1至图8所示，一种简易呼吸器，包括呼吸器支架1，如图3所示，呼吸器支架1的顶部固定安装有气囊隔腔2，气囊隔腔2的两侧均固定安装有给气球囊3，给气球囊3的一端均固定安装有进气阀4，进气阀4的一侧均固定安装有储气阀5和氧气管6，如图1所示，两个储气阀5和两个氧气管6的一端固定安装有同一个储氧带7，两个给气球囊3的另一端固定安装有同一个三通输气管8，三通输气管8靠近两个给气球囊3的两端上均设置有压力阀9和控制阀10，在本实施例中，两个控制阀10的内部均设置有截止开关，用于控制两个给气球囊3与三通输气管8的连通，三通输气管8远离给气球囊3的一端固定安装有单向阀11，单向阀11的底端设置有面罩组件；具体的为，该简易呼吸器通过设置两个给气球囊3，分别用于成人和儿童的给气，在使用时，可以根据患者的年龄将面罩组件的外形进行更改，然后按压对应的给气球囊3，使混合潮气可以依次经进气阀4、正向磁吸板39、控制阀10、三通输气管8和单向阀11向面罩组件内部输送，辅助患者呼吸，由于两个给气球囊3以及配对的压力阀9、控制阀10等阀门组件的规格不同，使两个给气球囊3每次的输气量分别可以对应成人与儿童的给气量，将原先不同规格的呼吸器统合成同一个呼吸器中，有效规避抢救过程中呼吸器配备不全的风险；As shown in Figures 1 to 8, a simple respirator includes a respirator bracket 1. As shown in Figure 3, an airbag compartment 2 is fixedly installed on the top of the respirator bracket 1, and air supply balloons 3 are fixedly installed on both sides of the airbag compartment 2. An air intake valve 4 is fixedly installed on one end of the air supply balloon 3, and an air storage valve 5 and an oxygen tube 6 are fixedly installed on one side of the air intake valve 4. As shown in Figure 1, the same oxygen storage belt 7 is fixedly installed on one end of the two air storage valves 5 and the two oxygen tubes 6, and the same three-way air supply pipe 8 is fixedly installed on the other end of the two air supply balloons 3. Pressure valves 9 and control valves 10 are arranged on the two ends of the three-way air supply pipe 8 near the two air supply balloons 3. In the present embodiment, cut-off switches are arranged inside the two control valves 10 for controlling the connection between the two air supply balloons 3 and the three-way air supply pipe 8. The three-way air supply pipe 8 is far away from the air supply balloon 3. A one-way valve 11 is fixedly installed at one end, and a mask assembly is arranged at the bottom end of the one-way valve 11; specifically, the simple respirator is provided with two air supply balloons 3, which are used for air supply to adults and children respectively. When in use, the shape of the mask assembly can be changed according to the age of the patient, and then the corresponding air supply balloon 3 is pressed, so that the mixed tidal air can be sequentially delivered to the inside of the mask assembly through the air inlet valve 4, the positive magnetic suction plate 39, the control valve 10, the three-way air supply pipe 8 and the one-way valve 11 to assist the patient's breathing. Since the specifications of the two air supply balloons 3 and the matched pressure valves 9, the control valve 10 and other valve components are different, the air supply volume of the two air supply balloons 3 each time can correspond to the air supply volume of adults and children respectively, and the original respirators of different specifications are integrated into the same respirator, effectively avoiding the risk of incomplete respirator equipment during rescue;
面罩组件用于根据患者的年龄而被分别调节为儿童、成人两种面罩；The mask assembly is used to be adjusted into two types of masks, one for children and one for adults, according to the age of the patient;
如图4所示，面罩组件包括套接于单向阀11底端的对接管12，对接管12的底端固定安装有内圈气囊罩13，内圈气囊罩13的底部固定安装有第一塑形环14，第一塑形环14的底部固定安装有外圈气囊罩15，外圈气囊罩15的底部固定安装有第二塑形环16，内圈气囊罩13的顶部固定安装有连通管17和吹气管18，外圈气囊罩15的顶部开设有与连通管17相适配的接口，连通管17和吹气管18的一侧栓接有与分别连通管17、吹气管18相适配的塞盖19，如图5所示，对接管12与第一塑形环14之间、第一塑形环14与第二塑形环16之间均固定安装有多个塑性条20，多个塑性条20分别位于内圈气囊罩13和外圈气囊罩15的内部并沿对接管12的轴线均匀分布，在本实施例中，连通管17的一端与外圈气囊罩15顶部的接口可通过医用胶带进行胶接，以提高密封性；具体的为，通过设置面罩组件，使得在面对成年患者时，可以直接经吹气管18向内圈气囊罩13内部充气，鼓入的气体会经连通管17向外圈气囊罩15内部输送，使原本折叠干瘪的内圈气囊罩13和外圈气囊罩15鼓起形成碗状面罩，再将塞盖19塞入吹气管18的一端将内圈气囊罩13封闭，而在面对儿童患者时，将连通管17从外圈气囊罩15顶部的接口处拔出，然后把另一个塞盖19将连通管17封闭，使外圈气囊罩15保持干瘪状态，然后将外圈气囊罩15折叠在内圈气囊罩13的顶部，使内圈气囊罩13单独作为面罩使用，从而缩小面罩体积，使面罩可以适配儿童的面型，使该面罩组件可以根据患者的年龄而对外形和规格进行更改，提高该呼吸器的适用范围，通过设置塑性条20，使得在面罩组件充气展开后，排出内圈气囊罩13和外圈气囊罩15中多余的气体，使内圈气囊罩13和外圈气囊罩15不会过于鼓胀，同时通过折弯多个塑性条20以及第一塑形环14、第二塑形环16，来使内圈气囊罩13和外圈气囊罩15可以调整成需要的形状，使内圈气囊罩13和外圈气囊罩15(或单独的内圈气囊罩13)可以更加贴合患者面型，减少面罩与患者面部接缝处的气体泄漏，保证该呼吸器的正常使用。As shown in FIG4 , the mask assembly includes a butt joint 12 which is sleeved on the bottom end of the one-way valve 11, an inner ring airbag cover 13 is fixedly installed on the bottom end of the butt joint 12, a first shaping ring 14 is fixedly installed on the bottom of the inner ring airbag cover 13, an outer ring airbag cover 15 is fixedly installed on the bottom of the first shaping ring 14, a second shaping ring 16 is fixedly installed on the bottom of the outer ring airbag cover 15, a connecting pipe 17 and an air blowing pipe 18 are fixedly installed on the top of the inner ring airbag cover 13, an interface which is compatible with the connecting pipe 17 is opened on the top of the outer ring airbag cover 15, and a plug cover 19 which is compatible with the connecting pipe 17 and the air blowing pipe 18 is bolted on one side of the connecting pipe 17 and the air blowing pipe 18, as shown in the figure. 5, a plurality of plastic strips 20 are fixedly installed between the butt joint tube 12 and the first shaping ring 14, and between the first shaping ring 14 and the second shaping ring 16. The plurality of plastic strips 20 are respectively located inside the inner ring airbag cover 13 and the outer ring airbag cover 15 and are evenly distributed along the axis of the butt joint tube 12. In this embodiment, the interface between one end of the connecting tube 17 and the top of the outer ring airbag cover 15 can be glued by medical tape to improve the sealing performance. Specifically, by setting the mask assembly, when facing an adult patient, the inner ring airbag cover 13 can be directly inflated through the blowing tube 18, and the blown gas will be transported to the inner ring airbag cover 15 through the connecting tube 17. , so that the originally folded and deflated inner circle airbag cover 13 and outer circle airbag cover 15 are bulged to form a bowl-shaped mask, and then the plug cover 19 is inserted into one end of the blowing tube 18 to close the inner circle airbag cover 13. When facing a child patient, the connecting tube 17 is pulled out from the interface at the top of the outer circle airbag cover 15, and then the other plug cover 19 is used to close the connecting tube 17, so that the outer circle airbag cover 15 remains deflated, and then the outer circle airbag cover 15 is folded on the top of the inner circle airbag cover 13, so that the inner circle airbag cover 13 is used alone as a mask, thereby reducing the volume of the mask, so that the mask can be adapted to the face shape of children, so that the mask assembly can be adjusted in shape and specification according to the age of the patient. The modification improves the application range of the respirator. By setting the plastic strip 20, the excess gas in the inner ring airbag cover 13 and the outer ring airbag cover 15 can be discharged after the mask assembly is inflated and unfolded, so that the inner ring airbag cover 13 and the outer ring airbag cover 15 will not be too inflated. At the same time, by bending multiple plastic strips 20 and the first shaping ring 14 and the second shaping ring 16, the inner ring airbag cover 13 and the outer ring airbag cover 15 can be adjusted to a required shape, so that the inner ring airbag cover 13 and the outer ring airbag cover 15 (or a single inner ring airbag cover 13) can better fit the patient's face shape, reduce gas leakage at the seam between the mask and the patient's face, and ensure the normal use of the respirator.
如图6所示，呼吸器支架1的顶部转动安装有调向转杆25，调向转杆25的顶端和底端均固定套接有悬挂架26，两个悬挂架26相互靠近的一侧均转动安装有微型电动推杆27，两个微型电动推杆27的伸缩端相互靠近并固定安装有同一个推气压板28，两个给气球囊3位于两个推气压板28之间，呼吸器支架1的顶部固定安装有固定支架29，固定支架29的一侧固定安装有定位套筒30，调向转杆25转动安装在定位套筒30的内部，定位套筒30的顶端和底端两侧均固定安装有限位架31，如图8所示，位于同一侧的两个限位架31之间固定安装有同一个限位导杆32，如图7所示，微型电动推杆27靠近调向转杆25的一侧均固定安装有定位伸缩杆33，定位伸缩杆33的伸缩端均固定安装有限位滑套34，两个限位滑套34分别滑动套接在两个限位导杆32；具体的为，通过设置推气压板28，使得在需要按压给气球囊3时，可以旋转悬挂架26使其通过调向转杆25带动上下两个推气压板28同步旋转至指定给气球囊3的位置，推气压板28会在定位伸缩杆33、限位滑套34以及限位导杆32的限位作用下，平行移动至给气球囊3的顶部和底部，然后两个微型电动推杆27分别驱动两个推气压板28上下移动，对给气球囊3进行机械式按压，代替人工手动按压，不仅可以提高输气量的精准控制，还可以减少医护人员的疲劳强度。As shown in Figure 6, a steering rod 25 is rotatably installed on the top of the respirator bracket 1, and the top and bottom ends of the steering rod 25 are fixedly sleeved with a suspension frame 26, and a micro-electric push rod 27 is rotatably installed on the side where the two suspension frames 26 are close to each other. The telescopic ends of the two micro-electric push rods 27 are close to each other and fixedly installed with the same pushing air pressure plate 28, and the two air supply balloons 3 are located between the two pushing air pressure plates 28. A fixed bracket 29 is fixedly installed on the top of the respirator bracket 1, and a positioning sleeve 30 is fixedly installed on one side of the fixed bracket 29. The steering rod 25 is rotatably installed inside the positioning sleeve 30, and both sides of the top and bottom ends of the positioning sleeve 30 are fixedly installed. As shown in Figure 8, the same limiting guide rod 32 is fixedly installed between the two limiting frames 31 on the same side. As shown in Figure 7, the micro-electric push rod 27 is close to the steering rod A positioning telescopic rod 33 is fixedly installed on one side of 25, and a limiting sleeve 34 is fixedly installed on the telescopic end of the positioning telescopic rod 33. The two limiting sleeves 34 are respectively slidably sleeved on the two limiting guide rods 32; specifically, by setting a push air pressure plate 28, when it is necessary to press the air supply balloon 3, the suspension frame 26 can be rotated so that it can drive the upper and lower push air pressure plates 28 to rotate synchronously to the position designated for the air supply balloon 3 through the adjustment rod 25. The push air pressure plate 28 will move parallel to the top and bottom of the air supply balloon 3 under the limiting action of the positioning telescopic rod 33, the limiting sleeve 34 and the limiting guide rod 32, and then the two micro electric push rods 27 respectively drive the two push air pressure plates 28 to move up and down, so as to mechanically press the air supply balloon 3 instead of manual pressing, which can not only improve the precise control of the gas supply volume, but also reduce the fatigue intensity of medical staff.
如图8所示，限位架31的一侧均固定安装有悬挂板36，悬挂板36靠近限位滑套34的一侧均固定安装有侧边磁吸板37与调频开关38，如图7所示，两个限位滑套34相互靠近的一侧均固定安装有磁性块35，位于同一侧的磁性块35与侧边磁吸板37、调频开关38的位置相对应，在本实施例中，位于同一侧的调频开关38与微型电动推杆27电性连接，同时调频开关38与单片机连接，通过触碰不同的调频开关38来选择微型电动推杆27的输出频率，两种调频开关38控制的输出频率分别适用于儿童与成人；具体的为，通过设置调频开关38，使得在推气压板28分别向两侧的给气球囊3移动时，两个磁性块35会随着限位滑套34在限位导杆32上的滑动而与其中一侧的侧边磁吸板37和调频开关38接触，从而被侧边磁吸板37吸附固定，有效避免推气压板28按压给气球囊3的过程中产生滑移，影响输气量控制的精准度，同时会触发该处的调频开关38，使调频开关38通过单片机调整当前微型电动推杆27的行进频率与行进范围，即调整当前推气压板28的按压频率与按压深度，实现给气量的调整与控制。As shown in FIG8 , a suspension plate 36 is fixedly installed on one side of the limit frame 31, and a side magnetic plate 37 and a frequency modulation switch 38 are fixedly installed on the side of the suspension plate 36 close to the limit sleeve 34. As shown in FIG7 , a magnetic block 35 is fixedly installed on the side where the two limit sleeves 34 are close to each other. The magnetic block 35 located on the same side corresponds to the position of the side magnetic plate 37 and the frequency modulation switch 38. In this embodiment, the frequency modulation switch 38 located on the same side is electrically connected to the micro electric push rod 27, and the frequency modulation switch 38 is connected to the single-chip microcomputer. The output frequency of the micro electric push rod 27 is selected by touching different frequency modulation switches 38. The output frequencies controlled by the two frequency modulation switches 38 are respectively suitable for children and Adults; specifically, by setting the frequency modulation switch 38, when the air pressure plate 28 moves to the air supply balloon 3 on both sides respectively, the two magnetic blocks 35 will contact with the side magnetic plate 37 and the frequency modulation switch 38 on one side as the limiting sliding sleeve 34 slides on the limiting guide rod 32, and are thereby adsorbed and fixed by the side magnetic plate 37, effectively avoiding slippage in the process of the air pressure plate 28 pressing the air supply balloon 3, thereby affecting the accuracy of air supply control, and at the same time triggering the frequency modulation switch 38 there, so that the frequency modulation switch 38 adjusts the current travel frequency and travel range of the micro electric push rod 27 through the single chip microcomputer, that is, adjusts the pressing frequency and pressing depth of the current air pressure plate 28, so as to achieve adjustment and control of the air supply volume.
如图3所示，气囊隔腔2的顶部和底部均固定安装有正向磁吸板39，正向磁吸板39与推气压板28的位置相对应，在本实施例中，推气压板28采用磁性金属制成，或者可在推气压板28内部设置磁性金属片；具体的为，通过设置正向磁吸板39，使得在该简易呼吸器闲置时，可将推气压板28转至两个给气球囊3之间的位置，然后两个微型电动推杆27伸展，带动推气压板28压向气囊隔腔2，并分别与两个正向磁吸板39接触，从而被正向磁吸板39吸附固定，进而防止两个推气压板28发生晃动，方便收纳，同时可在固定后推气压板28后，方便医护人员手动按压给气球囊3，满足该呼吸器的多种使用需求。As shown in Figure 3, positive magnetic attraction plates 39 are fixedly installed on the top and bottom of the airbag compartment 2. The positive magnetic attraction plates 39 correspond to the positions of the push air pressure plates 28. In the present embodiment, the push air pressure plates 28 are made of magnetic metal, or a magnetic metal sheet can be arranged inside the push air pressure plates 28. Specifically, by arranging the positive magnetic attraction plates 39, when the simple respirator is idle, the push air pressure plates 28 can be rotated to a position between the two air supply balloons 3, and then the two micro electric push rods 27 extend to drive the push air pressure plates 28 to press against the airbag compartment 2, and contact the two positive magnetic attraction plates 39 respectively, so as to be adsorbed and fixed by the positive magnetic attraction plates 39, thereby preventing the two push air pressure plates 28 from shaking, and facilitating storage. At the same time, after the push air pressure plates 28 are fixed, it is convenient for medical staff to manually press the air supply balloon 3, thereby meeting the various usage requirements of the respirator.
如图3所示，给气球囊3的周侧均固定安装有多个均匀分布的摩擦条301；具体的为，通过设置摩擦条301，使得摩擦条301可以增加手握给气球囊3的摩擦力，方便医护人员握持给气球囊3并进行按压。As shown in FIG3 , a plurality of evenly distributed friction strips 301 are fixedly installed around the circumference of the gas-feeding balloon 3; specifically, by providing the friction strips 301, the friction strips 301 can increase the friction force of holding the gas-feeding balloon 3, making it convenient for medical staff to hold the gas-feeding balloon 3 and press it.
如图4所示，吹气管18的一侧栓接有吹嘴21，吹嘴21与吹气管18相适配；具体的为，通过设置吹嘴21，使得在急救现场没有充气工具时，可将吹气管18一侧的吹嘴21取下并塞入吹气管18一端内，使吹嘴21与吹气管18对接，然后由医护人员经吹嘴21和吹气管18向内圈气囊罩13和外圈气囊罩15内部吹气，实现外圈魔术贴23和外圈气囊罩15的紧急充气，避免对急救工作造成影响。As shown in Figure 4, a nozzle 21 is bolted to one side of the blowing tube 18, and the nozzle 21 is adapted to the blowing tube 18; specifically, by providing the nozzle 21, when there is no inflation tool at the first aid site, the nozzle 21 on one side of the blowing tube 18 can be removed and inserted into one end of the blowing tube 18, so that the nozzle 21 and the blowing tube 18 are connected, and then the medical staff blows air into the inner ring airbag cover 13 and the outer ring airbag cover 15 through the nozzle 21 and the blowing tube 18 to realize emergency inflation of the outer ring Velcro 23 and the outer ring airbag cover 15, thereby avoiding affecting the first aid work.
如图4所示，内圈气囊罩13的顶部固定安装有多个内圈魔术贴22，外圈气囊罩15的顶部固定安装有多个外圈魔术贴23，外圈魔术贴23与内圈魔术贴22的位置相互对应，在本实施例中，内圈魔术贴22和外圈魔术贴23可分别为同组魔术贴的勾面与毛面；具体的为，通过设置内圈魔术贴22和外圈魔术贴23，使得在将面罩组件由成人规格替换为儿童规格时，可将干瘪的外圈气囊罩15折叠在内圈气囊罩13顶部，并使内圈魔术贴22与外圈魔术贴23对接相互粘黏，对外圈气囊罩15进行固定，避免对面罩组件的正常使用造成影响。As shown in Figure 4, a plurality of inner circle Velcro 22 are fixedly installed on the top of the inner circle airbag cover 13, and a plurality of outer circle Velcro 23 are fixedly installed on the top of the outer circle airbag cover 15. The positions of the outer circle Velcro 23 and the inner circle Velcro 22 correspond to each other. In this embodiment, the inner circle Velcro 22 and the outer circle Velcro 23 can be the hook surface and the fleece surface of the same group of Velcro respectively; specifically, by arranging the inner circle Velcro 22 and the outer circle Velcro 23, when the mask assembly is replaced from the adult specification to the child specification, the deflated outer circle airbag cover 15 can be folded on the top of the inner circle airbag cover 13, and the inner circle Velcro 22 and the outer circle Velcro 23 are connected and adhered to each other, so as to fix the outer circle airbag cover 15 and avoid affecting the normal use of the mask assembly.
如图4所示，外圈气囊罩15的底部设置有松紧套绳24，松紧套绳24的两端分别固定安装在外圈气囊罩15的顶部两侧，松紧套绳24的两端分别位于其中相邻的两个外圈魔术贴23之间；具体的为，通过设置松紧套绳24，使得松紧套绳24可以套接在患者的头部，使塑形后的面罩组件可以在松紧套绳24的弹性作用下紧密贴合患者面部，同时在外圈气囊罩15折叠固定在内圈气囊罩13上后，松紧套绳24的两端会有一部分也被折叠在内圈气囊罩13的顶部，进而缩短松紧套绳24的长度，使松紧套绳24的长度可以更加适配儿童的头型。As shown in Figure 4, an elastic loop 24 is provided at the bottom of the outer ring airbag cover 15, and the two ends of the elastic loop 24 are respectively fixedly installed on the two sides of the top of the outer ring airbag cover 15, and the two ends of the elastic loop 24 are respectively located between two adjacent outer ring Velcros 23; specifically, by providing the elastic loop 24, the elastic loop 24 can be sleeved on the patient's head, so that the shaped mask assembly can fit the patient's face tightly under the elastic action of the elastic loop 24, and at the same time, after the outer ring airbag cover 15 is folded and fixed on the inner ring airbag cover 13, a part of the two ends of the elastic loop 24 will also be folded on the top of the inner ring airbag cover 13, thereby shortening the length of the elastic loop 24, so that the length of the elastic loop 24 can be more suitable for the child's head shape.
综上：给气球囊3的选择：旋转悬挂架26使其通过调向转杆25带动上下两个推气压板28同步旋转至指定给气球囊3的位置，推气压板28会在定位伸缩杆33、限位滑套34以及限位导杆32的限位作用下，平行移动至指定给气球囊3的顶部和底部；In summary: Selection of the balloon 3: Rotate the hanging frame 26 to drive the upper and lower push air pressure plates 28 to rotate synchronously to the positions designated for the balloon 3 through the turning rod 25. The push air pressure plates 28 will move parallel to the top and bottom of the balloon 3 designated for the balloon under the limiting action of the positioning telescopic rod 33, the limiting sliding sleeve 34 and the limiting guide rod 32;
按压频率的调整：在推气压板28分别向两侧的给气球囊3移动时，两个磁性块35会随着限位滑套34在限位导杆32上的滑动而与其中一侧的侧边磁吸板37和调频开关38接触，从而被侧边磁吸板37吸附固定，有效避免推气压板28按压给气球囊3的过程中产生滑移，影响输气量控制的精准度，同时会触发该处的调频开关38，使调频开关38通过单片机调整当前微型电动推杆27的行进频率与行进范围，即调整当前推气压板28的按压频率与按压深度，实现给气量的调整与控制；Adjustment of pressing frequency: When the air pressure plate 28 moves toward the air supply balloon 3 on both sides respectively, the two magnetic blocks 35 will contact the side magnetic plate 37 and the frequency modulation switch 38 on one side as the limiting sliding sleeve 34 slides on the limiting guide rod 32, and are thus adsorbed and fixed by the side magnetic plate 37, effectively avoiding slippage in the process of the air pressure plate 28 pressing the air supply balloon 3, which affects the accuracy of air supply control. At the same time, the frequency modulation switch 38 there will be triggered, so that the frequency modulation switch 38 adjusts the current travel frequency and travel range of the micro electric push rod 27 through the single chip microcomputer, that is, adjusts the pressing frequency and pressing depth of the current air pressure plate 28, so as to adjust and control the air supply amount;
面罩组件的调整：在面对成年患者时，可以直接经吹气管18向内圈气囊罩13内部充气，鼓入的气体会经连通管17向外圈气囊罩15内部输送，使原本折叠干瘪的内圈气囊罩13和外圈气囊罩15鼓起形成碗状面罩，再将塞盖19塞入吹气管18的一端将内圈气囊罩13封闭，而在面对儿童患者时，将连通管17从外圈气囊罩15顶部的接口处拔出，然后把另一个塞盖19将连通管17封闭，使外圈气囊罩15保持干瘪状态，然后将外圈气囊罩15折叠在内圈气囊罩13的顶部，使内圈气囊罩13单独作为面罩使用，从而缩小面罩体积，使面罩可以适配儿童的面型，同时，排出内圈气囊罩13和外圈气囊罩15中多余的气体，使内圈气囊罩13和外圈气囊罩15不会过于鼓胀，同时通过折弯多个塑性条20以及第一塑形环14、第二塑形环16，来使内圈气囊罩13和外圈气囊罩15可以调整成需要的形状，使内圈气囊罩13和外圈气囊罩15(或单独的内圈气囊罩13)可以更加贴合患者面型；Adjustment of the mask assembly: When facing an adult patient, the inner circle airbag cover 13 can be inflated directly through the air blowing tube 18, and the inflated gas will be transported to the outer circle airbag cover 15 through the connecting tube 17, so that the originally folded and deflated inner circle airbag cover 13 and outer circle airbag cover 15 will swell to form a bowl-shaped mask, and then the plug cover 19 will be inserted into one end of the air blowing tube 18 to close the inner circle airbag cover 13. When facing a child patient, the connecting tube 17 is pulled out from the interface at the top of the outer circle airbag cover 15, and then the other plug cover 19 is used to close the connecting tube 17, so that the outer circle airbag cover 15 remains deflated, and then the outer circle airbag cover 15 is closed. Folding on the top of the inner circle airbag cover 13, the inner circle airbag cover 13 is used as a mask alone, thereby reducing the volume of the mask so that the mask can be adapted to the face shape of children. At the same time, the excess gas in the inner circle airbag cover 13 and the outer circle airbag cover 15 is discharged so that the inner circle airbag cover 13 and the outer circle airbag cover 15 will not be too bulging. At the same time, by bending a plurality of plastic strips 20 and the first shaping ring 14 and the second shaping ring 16, the inner circle airbag cover 13 and the outer circle airbag cover 15 can be adjusted into a desired shape so that the inner circle airbag cover 13 and the outer circle airbag cover 15 (or the inner circle airbag cover 13 alone) can better fit the patient's face shape;
呼吸器的使用：将松紧套绳24套接在患者的头部，使塑形后的面罩组件在松紧套绳24的弹性作用下紧密贴合患者面部，两个微型电动推杆27分别驱动两个推气压板28上下移动，对给气球囊3进行机械式按压，代替人工手动按压，使混合潮气可以依次经进气阀4、正向磁吸板39、控制阀10、三通输气管8和单向阀11向面罩组件内部输送，辅助患者呼吸，由于两个给气球囊3以及配对的压力阀9、控制阀10等阀门组件的规格不同，使两个给气球囊3每次的输气量分别可以对应成人与儿童的给气量。Use of the respirator: Put the elastic rope 24 on the patient's head so that the shaped mask assembly fits tightly to the patient's face under the elastic effect of the elastic rope 24. Two miniature electric push rods 27 drive the two air pressure plates 28 to move up and down respectively, and mechanically press the air supply balloon 3 instead of manual pressing, so that the mixed tidal gas can be transported to the inside of the mask assembly through the air inlet valve 4, the positive magnetic suction plate 39, the control valve 10, the three-way air supply pipe 8 and the one-way valve 11 in sequence to assist the patient's breathing. Since the specifications of the two air supply balloons 3 and the matching pressure valves 9, control valves 10 and other valve components are different, the air supply volume of the two air supply balloons 3 each time can correspond to the air supply volume of adults and children respectively.
