技术领域technical field
本发明涉及急诊治疗器械技术领域，特别是一种自适应心肺复苏胸外按压装置。The invention relates to the technical field of emergency treatment equipment, in particular to an adaptive cardiopulmonary resuscitation chest compression device.
背景技术Background technique
传统的胸外心脏复苏，大都采用操作者双手在患者的胸按压部，有节奏地按压的方法，来实现的。按压时要求：按压下陷深度3-5cm，按压频率为100-120次／min，因而操作强度较大。在实际操作中，往往因操作者手臂伸不直，形成手掌用力不均；或因操作者体力消耗过大，需频繁地交换操作者等诸多原因，影响按压的效果，特别是易出现肋骨骨折等并发症。Traditional chest resuscitation mostly uses the operator's hands on the chest compression part of the patient to press rhythmically to achieve. Requirements for pressing: the depression depth of pressing is 3-5cm, and the pressing frequency is 100-120 times/min, so the operation intensity is relatively high. In the actual operation, often because the operator's arm is not straight, resulting in uneven force on the palm; or because the operator's physical exertion is too large, the operator needs to be replaced frequently and many other reasons, which affect the effect of pressing, especially prone to rib fractures and other complications.
指南中“对于儿童(包括婴儿[小于一岁]至青春期开始的儿童)，按压深度胸部前后径的三分之一，大约相当于婴儿4厘米，儿童5厘米。对于青少年即应采用成人的按压深度，即5～6厘米” 、“最大不应超过6cm”。In the guideline, "For children (including infants [less than one year old] to children starting puberty), the compression depth is one-third of the anteroposterior diameter of the chest, which is approximately equivalent to 4 cm for infants and 5 cm for children. For adolescents, adult compression should be used Depth, that is, 5 to 6 cm", "The maximum should not exceed 6 cm".
现有技术中，专利申请号为201810829945.2的文件中，公布了一种心脏复苏自动按压机，其中为了适应不同胖瘦的患者，在固定架两侧设置两个活动支脚，每个活动支脚可以在0-21cm范围内伸缩，并将伸缩分为步长为1cm，是一种有级调节，然而不同人体之间差异可大可小，使用过程中会出现按压不足或者按压过重，效果不佳。并且该方案中的支腿两侧都有，需要根据不同的个体来分别调节两侧的支腿伸缩量，需要一一进行校准，才能使用，操作繁琐，耽误治疗抢救时间。In the prior art, in the document with the patent application number 201810829945.2, an automatic cardiac resuscitation press machine is announced. In order to adapt to different fat and thin patients, two movable legs are set on both sides of the fixed frame. Each movable leg can It stretches within the range of 0-21cm, and divides the stretch into steps of 1cm, which is a step-by-step adjustment. However, the difference between different human bodies can be large or small. During use, there will be insufficient or excessive pressure, and the effect is not good. good. In addition, the outriggers in this solution are on both sides, and the expansion and contraction of the outriggers on both sides need to be adjusted according to different individuals. It needs to be calibrated one by one before it can be used. The operation is cumbersome and delays the treatment and rescue time.
专利申请号为201710606671.6的文件中公布了一种器械式心肺复苏装置，其中为了实现适应不同的按压深度，其中也是采用不同的凸轮的偏心量来实现调整按压深度，也是属于有级调节，该装置要根据不同的个体进行现场安装不同的凸轮，在急诊现场，时间就是生命，该种操作显然繁琐浪费时间。除此之外，第二电动伸缩杆需要人为的进行调整使其下端能抵住人体，第二电动伸缩杆的伸缩量还是要靠人为观察，施救现场环境嘈杂气氛紧张，人为调整极为容易出现过度贴紧或者根本都没有贴紧，导致按压不足或者过度按压，影响按压效率，耽误按压质量。The patent application number is 201710606671.6, which discloses a device-type cardiopulmonary resuscitation device. In order to adapt to different compression depths, different cam eccentricities are used to adjust the compression depth, which is also a step-by-step adjustment. The device It is necessary to install different cams on site according to different individuals. At the emergency site, time is life, and this kind of operation is obviously a tedious waste of time. In addition, the second electric telescopic rod needs to be manually adjusted so that its lower end can touch the human body. The expansion and contraction of the second electric telescopic rod still depends on human observation. The environment at the rescue site is noisy and tense, and manual adjustment is extremely easy to occur Too tight or not tight at all, resulting in under-pressing or over-pressing, which affects the efficiency of pressing and delays the quality of pressing.
专利申请号为201811350405.2的文件中公布一种心肺复苏胸外自动按压设备及按压自反馈系统，其中利用模块化方案进行参数化处理，但是人体的胸径前后距离还是靠人为估测，还是可能会造成按压效果不理想，并且多个模块化操作造成整个装置比较笨重且不方便携带。The document with the patent application number 201811350405.2 discloses an automatic chest compression device for cardiopulmonary resuscitation and a compression self-feedback system, in which a modular scheme is used for parameterization processing, but the distance between the front and back of the chest diameter of the human body is still manually estimated, which may still cause The pressing effect is not ideal, and multiple modular operations cause the whole device to be bulky and inconvenient to carry.

本装置中，当横板2向上移动时，斜板15使得横杆12带动竖杆14向左移动并逐渐远离齿轮的的中心，由于凸起块11的呈圆锥的一半，且圆锥的顶角朝向盘形齿轮7的圆心，所以当竖杆14向左移动时，盘形齿轮7转动能使竖杆14上下移动的距离逐渐增大，与此过程中，竖杆14上下移动的距离等于横板2上升距离的三分之一。In this device, when the horizontal plate 2 moves upward, the inclined plate 15 makes the horizontal bar 12 drive the vertical bar 14 to move to the left and gradually away from the center of the gear. Towards the center of the disc gear 7, so when the vertical rod 14 moves to the left, the rotation of the disc gear 7 can gradually increase the distance of the vertical rod 14 moving up and down, and during this process, the vertical rod 14 moves up and down. Plate 2 rises one-third of the distance.
初始状态下，竖杆14与盘形齿轮7同轴，凸起块11处于竖杆14的右侧，盘形齿轮7转动时竖杆14在上下方向上不发生位移，按压块9的下端面与支撑杆3的下端面平齐，按压块9的直径大于压杆8的直径，即按压块9一直处于横板2下方；竖杆14处于盘形齿轮7的外缘部分时，竖杆14在上下方向上移动的距离最大，竖杆14在上下方向移动的最大距离不大于6cm；斜板15分上下两部分，上端部分为倾斜状，下端部分为竖直状，当人体胸径前后距离过大时，保证横杆12不会继续向左推动竖杆14，保证最大按压深度不大于6cm，保证人体不受二次伤害；斜板15最顶端距离斜板15下端之间的水平距离不大于盘形齿轮7的半径。In the initial state, the vertical bar 14 is coaxial with the disc gear 7, and the raised block 11 is on the right side of the vertical bar 14.

The upper end keeps in contact with the disc gear 7, and as the vertical rod 14 gradually moves away from the center of the gear, the rotation of the disc gear 7 can gradually increase the displacement of the vertical rod 14 in the up and down direction until the support rod 3 touches the ground. Move the compression screw on the sliding cylinder 17, the compression screw makes the horizontal plate 2 and the support rod 3 fixed together, connects the motor 18, the rotation of the motor 18 drives the long gear 4 to rotate, and the long gear 4 drives the disc gear 7 to rotate. The rotating cylinder 5 and the rotating shaft 6 at this time have been fixed together, and the rotating cylinder 5 cannot move up and down, so the disc gear 7 can only rotate but cannot move up and down. Rod 14 moves up and down, and vertical bar 14 moves up and down through boss 10 and drives depression rod 8 to move up and down, and depression rod 8 moves up and down through pressing block 9 and realizes pressing to human body.
本发明中，为了保证斜板15的支撑强度，所述的斜板15与横板2之间焊接有多个加强筋。In the present invention, in order to ensure the supporting strength of the sloping plate 15, a plurality of reinforcing ribs are welded between the sloping plate 15 and the horizontal plate 2.
本发明中，正常情况下，凸起块11使得竖杆14上下移动的高度等于横板2上升距离的三分之一，当人体胸径前后距离过大时，斜板15不在迫使横杆12向左移动，使得按压深度不超过6cm，保证人体安全。In the present invention, under normal circumstances, the raised block 11 makes the vertical bar 14 move up and down at a height equal to one-third of the rising distance of the horizontal plate 2. Move to the left so that the pressing depth does not exceed 6cm to ensure the safety of the human body.
本发明的突出优点及显著进步：Outstanding advantages and remarkable progress of the present invention:

In the present invention, the rising distance of the horizontal plate 2 is equal to the distance before and after the chest diameter of the human body, and the rotating shaft 6 and the rotating drum 5 can be fixed at any time, and the horizontal plate 2 can be fixed at any height of the support rod 3, which belongs to stepless adjustment and can be well It is suitable for different individuals, and the rescue site only needs to buckle the device on the patient, and it is easy to operate, saves time, and is beneficial to the rescue of patients.
2.本发明中将人体厚度与竖杆14能后上下移动的距离关联起来，使得竖杆14向下移动的距离等于人体前后胸径大小的三分之一，当个体较胖时，竖杆14处于盘形齿轮7的外缘且不再向外侧移动，此时凸起块11使得竖杆14向下移动的距离不大于6cm，有效防止患者出现并发症。2. In the present invention, the thickness of the human body is associated with the distance that the vertical rod 14 can move up and down, so that the distance that the vertical rod 14 moves downward is equal to one-third of the front and rear diameter of the human body.
