Description

  The present invention relates to a chest compression system, and more particularly to a chest compression system capable of stably performing chest compression on a patient being transported.

  Cardiopulmonary resuscitation is an emergency procedure that is performed to save human life when the heart stops functioning. The center of the chest is used at the base of the hand and the appropriate pressure is applied at a rate of 100 to 120 times per minute. Is a first aid. If the heart stops, cardiopulmonary resuscitation must be continued until the patient is transported to the hospital, and patient survival depends on how well the cardiopulmonary resuscitation was performed. Therefore, effective cardiopulmonary resuscitation until arrival at the hospital is the most important treatment in emergency situations.

  Conventionally, it has been very difficult to perform accurate chest compression on a patient with cardiac arrest during transportation by a stretcher or an emergency vehicle. This is because chest compression is very difficult due to the shaking and vibration of the stretcher and the car, it is difficult to take the posture to perform chest compression, the recoil of the whole upper body with the elbows straightened and the combination of both hands This is because chest compression must be performed on patients with cardiac arrest using the Therefore, the rescuer's fatigue becomes very high, making it difficult to continue chest compressions in a sustained and efficient manner, and there is a risk of potential safety accidents such as a rescuer's lower back injury, as well as inaccurate chest compressions. In some cases, internal fractures such as rib fractures were induced.

  In addition, although there is a cardiopulmonary resuscitation equipment (automatic cardiopulmonary resuscitator), it is very expensive, requires a separate power supply, and is too heavy, so it is being transported to the hospital. The application rate was very low for patients with cardiac arrest. Due to these problems, in Japan, an average of 25,000 patients (excluding those who died at home) suffered from cardiac arrest every year, but the resuscitation rate was very low. According to statistics from the Ministry of Health and Welfare, the resuscitation rates in the United States and Japan are 9.6% and 8.8%, respectively, whereas Japan is only 3%.

  In this connection, a conventional cardiopulmonary resuscitation device is disclosed in the Korean Registered Patent Publication No. KR7066701. Referring to FIG. 1, a block diagram of a conventional cardiopulmonary resuscitation device is shown. The conventional cardiopulmonary resuscitation apparatus includes a compression depth adjuster 38 and a compression depth adjuster drive unit 40, and the compression depth adjuster 38 corresponds to an adjustment signal of the chest compression depth, and the compression depth adjuster drive unit 40. Drive to adjust the chest compression depth. However, although the above-mentioned patent document considers the control aspect of chest compression such as chest compression depth adjustment, it provides a method for stably performing chest compression on a patient being transported by a stretcher or a car. Absent.

  Therefore, the present invention provides a chest compression system that not only can be easily coupled to a stretcher, but also can stably perform chest compression during the transportation of a patient on the stretcher.

  FIG. 2 is an exemplary view of a chest compression system 100 according to a preferred embodiment of the present invention.

  Referring to FIG. 2, the chest compression system 100 of the present invention includes a support frame 110, a main body 120, and a connecting part 130.

  The support frame 110 is formed in a curved shape so as to surround the human chest. The patient will be laid inside the support frame 110, and the support frame 110 is positioned on the patient. The main body 120 is formed on the upper end of the support frame 110, which is a position where a constant compression can be performed from above the chest of the patient.

  The support frame 110 can be formed of a stable structure and material so that the chest compression can be performed without the main body 120 being twisted. The support frame 110 includes a connecting portion 130 serving as a leg at a side end, and comes into contact with the ground. The material of the support frame 110 is preferably a curable resin or a metal material because it is necessary to withstand the continuous reciprocation of the main body 120.

  The main body 120 includes a compression rod 121, an elastic body 122, a compression plate 123, a compression portion 124, and a handle 125.

  The main body 120 is formed at the upper end of the support frame 110 and compresses the chest from the set position 101 to the compression position 102 by an external force, and performs a reciprocating motion to restore from the compression position 102 to the set position 101 after the chest compression. Specifically, when an external force is applied to the compression portion 124, the external force squeezes the elastic body 122, and the elastic body 122 lowers the compression rod 121 by a height h from the setting position 101 to the compression position 102. The compression plate 123 descending corresponding to the compression rod 121 applies pressure by the external force to the chest while descending from the set position 101 to the compression position 102. When the external force is exhausted from the compression portion 124, the compression plate 123 rises from the compression position 102 to the setting position 101 by the restoring force of the elastic body 122, and the compression rod 121 also has a height h from the setting position 101 to the compression position 102. To rise.

  The main body 120 can adjust the setting position 101. The setting position 101 determines the compression strength and the compression speed according to the interval between the compression position 102 and the compression position 102. The main body 120 can include an adjusting unit 126 that can adjust the setting position 101, and the compression strength and the compression speed can be determined by adjusting the setting position 101 that is the start position of the compression plate 123. The adjustment unit 126 will be described later.

  When the reciprocation between the setting position 101 and the compression position 102 of the main body 120 is not performed, the main body that has compressed the chest from the setting position 101 to the compression position 102 by an external force is fixed to the setting position 101.

  When an external force is applied to the compression part 124, the external force is transmitted as pressure to the chest in the order of the elastic body 122, the compression rod 121, and the compression plate 123. Here, the compression plate 123 can be fixed to the compression position 102 and constantly applies pressure to the chest.

  The compression rod 121 reciprocates from the setting position 101 to the compression position 102 of the chest by an external force applied from the compression unit 124. Further, as described above, the compression rod 121 can be fixed in a state where the chest is compressed at the compression position 101.

  When the compression rod 121 reciprocates, the compression rod 121 can be passively operated by external human power, but can automatically operate including an electronic circuit.

  The elastic body 122 provides a restoring force for restoring the compression rod 121 to the set position 101. When an external force is applied to the compression portion 124, the elastic body 122 is contracted and the compression rod 121 is lowered. When the external force is removed from the compression portion 124, the elastic body 122 is restored to the original, and the compression rod 121 is raised to the set position 101 by the restoring force of the elastic body 122.

  The compression plate 123 transmits external force as pressure to the chest. The compression plate 123 is formed at one end of the compression rod 121, and is in close contact with the chest during compression to transmit the pressure due to the external force from the compression rod 121 to the chest.

  An external force from the outside is input to the compression unit 124. The external force may be a human power by a person performing cardiopulmonary resuscitation. The compression portion 124 is formed at the other end of the compression rod 121 where the compression plate 123 is not provided. The compression part 124 is formed larger than the radius of the compression rod 121 in order to easily receive an external force so that the area to which the external force is input becomes large.

  The handle 125 is formed at the side end of the compression portion 124 and applies an external force to the main body 120. The handle 125 has a structure that can be bent up and down from the side end of the compression portion 124. The handle 125 can receive the input of the external force in an extended state or a vertically folded state depending on the form in which the external force is applied. Preferably, the handle 125 is easy to bend and can be formed in a rod shape to easily receive an external force.

  The connecting portion 130 is formed at a side end of the support frame 110 and can couple the stretcher 200 and the support frame 110 together. The connecting portion 130 is mainly used when the chest compression system 100 is coupled to the stretcher 200, but can also be in contact with the ground together with the lower end of the support frame 110 even when not coupled to the stretcher 200.

  A spring can be used as a method in which the connecting portion 130 couples the support frame 110 and the stretcher 200. The connecting portion 130 may include an inner space 131 that can be coupled to the stretcher 200. The inner space 131 of the connecting portion 130 is normally closed, but when the connecting portion 130 is pulled to the outside, the spring is released. When the connecting portion 130 is restored in a state where the inner space 131 appears and the inner space 131 and the stretcher handle 510 are coupled, the connecting portion 130 can be fixed to the stretcher handle 510. The restoring force of the spring included in the connecting portion 130 can be tightened in a state where the stretcher 200 coupled to the inner space 131 is squeezed. Preferably, the connecting portion 130 can be coupled to the handle 510 of the stretcher positioned at the edge of the stretcher 200, but is not limited thereto, and any support can be used as long as it can be coupled to the inner space 131 of the connecting portion 130 anywhere on the stretcher 200. The frame 110 can be coupled to the stretcher 200.

  The connection part 130 includes an electromagnet (not shown), and the support frame 110 can be coupled to the stretcher 200 using the electromagnet. The connection part 130 includes an electromagnet inside and can be electrically connected to the handle 125. Specifically, the handle 125 is connected to an electromagnet included in the connection unit 130 to control the electromagnet. When the handle 125 is bent up and down, the electromagnet loses magnetism so that the support frame 110 and the stretcher 200 are separated from each other. When the handle 125 is extended, electricity can be passed through the electromagnet so that it has magnetism. The stretcher 200 and the support frame 110 can be coupled together.

  FIG. 3 is a detailed view of the adjusting part of the chest compression system according to a preferred embodiment of the present invention.

  Referring to an enlarged view of the adjustment unit 126 of FIG. 3, the main body 120 includes an adjustment unit 126 that adjusts the setting position 101.

  Adjustment unit 126 includes an outer cylinder 126-1 and an inner cylinder 126-2. The outer cylinder 126-1 has an adjustment pattern 126-11 on the surface, and the inner cylinder 126-2 is retracted. The inner cylinder 126-2 includes a protruding portion 126-21 that penetrates the compression rod 121 having an elastic body 122 therearound and is sandwiched between the adjustment patterns 126-11 on the surface. An anti-slip dial 126-22 that can change the position of the protrusion 126-21 corresponding to the adjustment pattern 126-11 is formed below the inner cylinder 126-2.

  The adjustment unit 126 can adjust the setting position 101 according to the coupling state between the adjustment pattern 126-11 and the protrusion 126-21. The protrusion 126-21 is sandwiched between the adjustment patterns 126-11 and moves in a sliding manner, and the movement direction can be moved along the dotted arrow direction. The set position 101 of the internal cylinder 126-2 is determined by which height of the adjustment pattern 126-11 the protrusion 126-21 is sandwiched.

  The adjustment pattern 126-11 may have a bowl shape, and each pattern has a constant interval. In this drawing, an example in which each pattern and the interval between patterns is 1 cm is shown. One vertical adjustment pattern 126-11 adjusts the height of the inner cylinder 126-2, and the three horizontal adjustment patterns 126-11 serve to fix the protrusion 126-21 at a specific position. . The protrusion 126-21 moves along the adjustment pattern 126-11 in the vertical direction and then moves to the back along the adjustment pattern 126-11 in the horizontal direction.

  When the protrusion 126-21 is sandwiched between the highest position patterns (patterns that are 5 cm apart), the setting position 101 is also lowered by lowering the inner cylinder 126-2. When the protrusion 126-21 is sandwiched between the lowest position patterns (patterns that are 1 cm apart), the set position 101 is also increased by raising the internal cylinder 126-2.

  An anti-slip dial 126-22 formed at the lower portion of the inner cylinder 126-2 adjusts the position of the protrusion 126-21 corresponding to the adjustment pattern 126-11 while moving the inner cylinder 126-2 left and right. . To prevent the user's hand from slipping when the user turns the inner cylinder 126-2, the anti-slip dial 126-22 forms a pattern with high friction on the surface or includes a material with high friction. The user of the chest compression system 100 can adjust the set position 101 where compression starts, while turning the anti-slip dial 126-22 left and right as indicated by the arrow.

  FIG. 4 is a detailed view of an adjusting unit having an anti-motion volume of a chest compression system according to a preferred embodiment of the present invention.

  Referring to FIG. 4, a motion prevention volume 126-12 formed inside the adjustment pattern 126-11 is shown. The movement preventing volume 126-12 supports and fixes the protrusion 126-21 so that the protrusion 126-21 does not move inside the adjustment pattern 126-11.

  FIG. 5 is a perspective view of a chest compression system coupled to a stretcher according to a preferred embodiment of the present invention.

  Referring to FIG. 5, a chest compression system 100 coupled to a stretcher 200 is shown. The chest compression system 100 can be coupled to the stretcher 200 and is normally fixed to the stretcher 200 and cannot be moved in the coupled state, but can be moved along the arrow direction to change the coupling position.

  FIG. 6 is an exemplary view showing that a chest compression system according to a preferred embodiment of the present invention is actually used.

  Referring to FIG. 6, it is shown that an emergency rescuer performs cardiopulmonary resuscitation on a patient on a stretcher 200 to which the chest compression system 100 is coupled. While the patient is being transported, an emergency rescuer puts his hand on the compression unit 124 and continuously applies pressure. Even while the patient is being transported, since the support frame 110 and the patient are fixed to the stretcher 200, the emergency rescuer can apply an external force to the same chest position at a constant speed and strength.

  FIG. 7 is a view illustrating an example of a support frame before a width is adjusted according to another preferred embodiment of the present invention, and FIG. 8 is a diagram illustrating a width adjusted according to another preferred embodiment of the present invention. It is an illustration figure of a back support frame.

  In the support frame 110, the interval between the side ends of the support frame 110 is adjusted according to the width of the stretcher 200. Specifically, the support frame 110 includes an adjustment table 140 and an adjustment slide 150 at the upper end, and the width is adjusted by the movement of the adjustment table 140 and the adjustment slide 150. More specifically, the adjustment base 140 has a structure that can move left and right within the adjustment slide 150. When the support frame 110 maintains a narrow spacing, the adjustment platform 140 is located in the vicinity of the main body 120 on the adjustment slide 150. When the support frame 110 maintains a wide interval, the adjustment base 140 is positioned far from the main body 120 on the adjustment slide 150.

  Comparing FIGS. 7 and 8, the chest compression system 100 has an adjustment platform 140 that moves along the adjustment slide 150 to couple to a wide stretcher 200, and the width of the support frame 110 is reduced to both by d respectively. It is shown that it has stretched.

  FIG. 9 is an exemplary view of a chest compression system coupled to a stretcher according to still another preferred embodiment of the present invention.
