In addition, if a proximity sensor (270) for sensing the position of a guide protrusion (231a) is added, the height of the guide protrusion (231a) is sensed using the proximity sensor (270) so that the height of the lifting/lowering unit (230) can be automatically controlled, and thus the effect of enabling the training intensity to be accurately and conveniently adjusted is also expected.

Description

기능이 뛰어난 심폐소생술 훈련인형Highly functional CPR training doll
본 발명은 심폐소생술 훈련인형에 관한 것으로, 특히 훈련자의 신체 능력에 적합하게 훈련 강도를 조절할 수 있는 심폐소생술 훈련인형에 관한 것이다.The present invention relates to a CPR training doll, and particularly to a CPR training doll that can adjust the training intensity to suit the physical abilities of the trainee.
심정지의 발생은 예측이 어려워서 대부분의 심정지는 의료시설 이외의 장소에서 발견되는데, 심정지가 발생된 후 4~5분이 경과되면 뇌가 비가역적 손상을 받기 때문에 심정지를 목격한 사람의 신속한 응급처치는 매우 중요하다. 여러가지 응급처치 중에서도 최상의 응급처치는 목격자에 의한 심폐소생술이므로, 심폐소생술 교육이 모든 이들을 대상으로 하여 점차 확대되고 있는 실정이다.The occurrence of cardiac arrest is difficult to predict, so most cardiac arrests are discovered in places other than medical facilities. Since the brain is irreversibly damaged 4 to 5 minutes after cardiac arrest occurs, it is very important for people who witness a cardiac arrest to provide prompt first aid. It is important. Among various first aid measures, the best first aid is CPR by bystanders, so CPR training is gradually expanding to include everyone.
특히 심폐소생술(cardiopulmonary resuscitation ; CPR) 훈련자가 CPR 훈련인형을 대상으로 심폐소생술을 직접 시행토록 하는 훈련법이 일반적이며, 이를 위해서 다양한 형태의 CPR 훈련인형이 개발되어 사용되고 있다.In particular, the training method of having a cardiopulmonary resuscitation (CPR) trainer directly perform CPR on a CPR training doll is common, and for this purpose, various types of CPR training dolls have been developed and used.
그러나, 종래 CPR 훈련인형은 훈련자의 신체 능력에 따라서 훈련 강도를 조절할 수 있도록 되어 있지 못해서, 연령별로 훈련 강도를 달리한 연령별 전용 CPR 훈련인형을 사용하고 있는 실정이다.However, conventional CPR training dolls are not designed to adjust the training intensity according to the physical ability of the trainee, so age-specific CPR training dolls with different training intensities depending on age are used.
이에 본 발명은 상기와 같은 문제를 해소하기 위해서 발명된 것으로, 훈련자의 신체 능력에 따라서 훈련 강도를 적절하게 조절할 수 있고, 동작이 원활하게 이루어지는 기능이 뛰어난 심폐소생술 훈련인형을 제공함에 그 목적이 있다.Accordingly, the present invention was invented to solve the above problems, and its purpose is to provide a highly functional CPR training doll that can appropriately adjust the training intensity according to the physical ability of the trainee and performs smooth movements. .
상기와 같은 목적을 달성하기 위한 본 발명은,The present invention to achieve the above object,
인형 본체의 내부에 스프링장치가 설치된 심폐소생술 훈련인형에 있어서,In the CPR training doll with a spring device installed inside the doll body,
상기 스프링장치는,The spring device is,
베이스 본체와, 가이드 구멍을 갖추고서 베이스 본체로부터 상방향으로 돌출되게 고정되는 승강 가이드로 이루어진 베이스와 ;A base consisting of a base body and a lifting guide provided with a guide hole and fixed to protrude upward from the base body;
상하면이 개방된 통형태를 이루는 스프링 수용부와, 스프링 수용부의 상면 일부 또는 전부를 밀폐하는 누름판으로 이루어져, 고정끈을 매개로 베이스 본체에 고정되는 누름유닛과 ;A pressing unit consisting of a spring receiving portion in the form of a cylinder with the upper and lower surfaces open, and a pressing plate sealing part or all of the upper surface of the spring receiving portion, and fixed to the base body via a fixing strap;
승강 가이드의 가이드 구멍에 끼워지는 가이드 돌기를 갖추고서 승강 가이드를 따라 상하방향으로 왕복 이동되는 승강유닛과 ;A lifting unit equipped with a guide protrusion fitted into the guide hole of the lifting guide and moving back and forth in the vertical direction along the lifting guide;
하부는 승강유닛에 얹혀져 고정되고, 상부는 누름유닛의 스프링 수용부에 수용되어, 승강유닛의 상부에 이격되게 배치된 누름유닛을 상방향으로 탄발 지지하는 스프링과 ;The lower part is mounted on and fixed to the lifting unit, and the upper part is accommodated in the spring receiving part of the pressing unit, and a spring elastically supports the pressing unit spaced apart from the upper part of the lifting unit in an upward direction;
베이스 본체에 회전 가능하게 고정되고, 승강유닛에 나사산 결합되어, 승강유닛을 상하방향으로 왕복 구동하는 회전유닛과 ; A rotation unit rotatably fixed to the base body, threadedly coupled to the lifting unit, and reciprocating the lifting unit in the up and down directions;
베이스 본체에 설치되어, 회전유닛을 구동하는 구동유닛을 포함하는 것을 특징으로 하는 구조로 되어 있다.It is installed on the base body and has a structure characterized by including a drive unit that drives the rotation unit.
또한, 본 발명에 따른 심폐소생술 훈련인형은, 상기 가이드 돌기의 위치를 감지하는 근접센서가 보강 구비된 것을 특징으로 한다.In addition, the CPR training doll according to the present invention is characterized by being reinforced with a proximity sensor that detects the position of the guide protrusion.
본 발명에 따르면, 구동유닛을 매개로 시계방향과 반시계방향으로 양방향 회동되는 회전유닛에 의해 승강유닛이 상하방향으로 높낮이 조절되는 구조이므로, 훈련자의 신체 능력에 따라서 훈련 강도를 적절하게 조절할 수 있게 되어, 훈련자의 신체 능력에 구애받지 않고 폭넓게 사용할 수 있는 효과가 기대된다.According to the present invention, the lifting unit has a structure in which the height of the lifting unit is adjusted up and down by a rotation unit that rotates in both clockwise and counterclockwise directions via the drive unit, so that the training intensity can be appropriately adjusted according to the physical ability of the trainee. Therefore, it is expected to have a wide range of uses regardless of the physical ability of the trainee.
또한, 고정끈을 매개로 베이스 본체에 고정된 누름유닛이 승강유닛의 상부에 이격되게 배치된 상태에서 스프링에 의해 상방향으로 탄발 지지되는 구조이므로, 심폐소생술 훈련시 누름유닛과 승강유닛 간의 상호 간섭이 효율적으로 방지되어, 심폐소생술 훈련시에 흉부 압박 동작이 흉부를 압박하는 방향에 관계없이 실제처럼 자연스럽게 이루어지고, 제작의 편이성이 향상되는 효과가 있다.In addition, since the pressing unit, which is fixed to the base body via a fixing strap, is elastically supported upward by a spring while being spaced apart from the upper part of the lifting unit, mutual interference between the pressing unit and the lifting unit is prevented during CPR training. This is effectively prevented, so that during CPR training, chest compressions are performed as naturally as the real thing regardless of the direction in which the chest is compressed, and the convenience of production is improved.
또한, 가이드 돌기의 위치를 감지하는 근접센서를 보강하면, 근접센서를 이용해서 가이드 돌기의 높낮이를 감지하여, 승강유닛의 높낮이를 자동으로 제어할 수 있게 되므로, 훈련 강도를 정확하면서도 편리하게 조절할 수 있는 효과도 기대된다.In addition, by reinforcing the proximity sensor that detects the position of the guide protrusion, the height of the guide protrusion can be detected using the proximity sensor and the height of the lifting unit can be automatically controlled, allowing the training intensity to be adjusted accurately and conveniently. Some effects are also expected.

도 5 내지 도 7을 참조하여, 본 발명에 따른 스프링장치(200)의 작동을 설명해 보면 다음과 같다.With reference to FIGS. 5 to 7, the operation of the spring device 200 according to the present invention will be described as follows.
우선, 도 6은 근접센서(270) 중에서 최하단에 배치된 제1센서(171)에 센서 감지부(231b)가 감지되어 정지된 상태, 즉 승강유닛(230)이 최하단 위치에 놓여진 상태를 도시한 것으로, 스프링(240)이 작동 가능한 범위 내에서 최대로 벌려진 상태를 나타내고 있다. 이러한 상태에서, 훈련자가 인형 본체(100)의 흉부를 하방향으로 눌러서 압박하게 되면, 훈련자가 가하는 압력(누름 하중)이 인형 본체(100)에 내설된 스프링장치(200)의 누름판(222)으로 전달되어, 스프링(240)이 눌려지면서 누름유닛(220)이 하방향으로 이동되는데, 스프링(240)은 작동 가능한 범위 내에서 최대로 벌려진 상태이므로, 승강유닛(230)은 작은 힘으로도 원활하게 하방향으로 눌려지게 된다.First, Figure 6 shows a state in which the sensor detection unit 231b is detected and stopped by the first sensor 171 disposed at the lowest position among the proximity sensors 270, that is, the lifting unit 230 is placed at the lowest position. This indicates that the spring 240 is fully opened within its operable range. In this state, when the trainee presses the chest of the doll body 100 downward, the pressure (pressing load) applied by the trainee is applied to the pressing plate 222 of the spring device 200 built into the doll body 100. When transmitted, the spring 240 is pressed and the pressing unit 220 moves downward. Since the spring 240 is opened to the maximum within the operable range, the lifting unit 230 moves smoothly even with a small force. is pressed downward.
도 7은 근접센서(270) 중에서 최상단에 배치된 제3센서(173)에 센서 감지부(231b)가 감지되어 정지된 상태, 즉 승강유닛(230)이 최상단 위치에 놓여진 상태를 도시한 것으로, 스프링(240)이 작동 가능한 범위 내에서 최대로 오므려진 상태를 나타내고 있다. 이러한 상태에서, 훈련자가 인형 본체(100)의 흉부를 하방향으로 눌러서 압박하게 되면, 훈련자가 가하는 압력(누름 하중)에 의해 누름유닛(220)이 하방향으로 이동되는데, 스프링(240)은 작동 가능한 범위 내에서 최대로 오므려진 상태이므로, 훈련자의 누르는 압력이 충분해야 승강유닛(230)이 원활하게 하방향으로 눌려지게 된다. 상기 스프링(240)의 탄성 강도는 필요에 따라서 다양하게 선택되어 적용될 수 있다.Figure 7 shows a state in which the sensor detection unit 231b is detected and stopped by the third sensor 173 disposed at the top among the proximity sensors 270, that is, the lifting unit 230 is placed at the top position. It shows the state in which the spring 240 is maximally retracted within its operable range. In this state, when the trainee presses the chest of the doll body 100 downward, the pressing unit 220 is moved downward by the pressure (pressing load) applied by the trainee, and the spring 240 operates. Since it is in the maximum retracted state within the possible range, the training pressure must be sufficient for the lifting unit 230 to be smoothly pressed downward. The elastic strength of the spring 240 can be selected and applied in various ways as needed.
한편, 본 발명의 경우, 승강유닛(230)의 상부에 이격되게 배치된 누름유닛(220)이 스프링(240)에 의해 상방향으로 탄발 지지되면서, 고정끈(10)을 매개로 베이스 본체(211)에 고정되는 구조를 이루므로, 심폐소생술 훈련시에 흉부 압박 동작이 수직이 아니라 비스듬하게 가해지더라도 누름유닛(220)이 승강유닛(230)에 간섭되지 않고 원활하게 이동되므로, 심폐소생술 훈련이 마치 사람을 대상으로 하는 것처럼 자연스럽게 이루어지게 된다. 또한, 구성요소들 간의 상호 결합 구조가 단순하게 되어, 제작의 편이성이 향상된다.Meanwhile, in the case of the present invention, the pressing unit 220 spaced apart from the upper part of the lifting unit 230 is elastically supported upward by the spring 240, and the base body 211 is supported by the fixing strap 10. ), so even if chest compressions are applied obliquely rather than vertically during CPR training, the pressing unit 220 moves smoothly without interfering with the lifting unit 230, so CPR training is as if it were It happens naturally, just like it does with people. In addition, the interconnection structure between the components is simplified, thereby improving the convenience of manufacturing.
이상 본 발명은 상기한 바와 같은 실시예에 한정되지 않고 공지의 범위 내에서 다양한 형태로 변형 실시될 수 있으며, 이러한 변형 실시예들 역시 본 발명의 권리범위에 포함되는 것으로 해석되어야 할 것이다.The present invention is not limited to the above-described embodiments and can be modified and implemented in various forms within the known scope, and these modified embodiments should also be construed as falling within the scope of the present invention.
