[0006] Chest compressions performed in the supine position, the standard CPR chest compression position, are common. Supine chest compressions in CPR increase blood volume and pressure in the arterial system and the right heart, which are then delivered to the brain via the jugular vein and paravertebral venous plexus. This increased blood volume and pressure increases intracranial pressure, reducing cerebral perfusion.

[0007] Intracranial pressure is typically elevated in patients in the supine position, and head elevation is commonly performed as a noninvasive method to reduce intracranial pressure in patients with traumatic brain injury.

[0008] Head-up CPR increases venous return from the brain to the heart, driven by gravity, reducing intracranial pressure and improving cardiac preload. Furthermore, several recent studies have shown that head-up CPR reduces intracranial perfusion, thereby increasing cerebral perfusion pressure and blood flow.

For example, a subject who is not an actual patient but acts as a patient, such as when practicing CPR using this device, is also included within the meaning of "patient." It should be understood that the scope of the present invention is not necessarily limited to a literal patient.

[0065] Below, a preferred embodiment of a head-up system according to the present invention is described in detail with reference to the attached drawings.

Fig. 10 is a front view showing a head-up system with a patient's head raised, Fig. 11 is a front view showing an operating part of the head-up system shown in Fig. 10, Fig. 12 is a front view showing a state in which the head curve is tilted in the state of Fig. 10, Fig. 13 is a front view showing an operating part of the head-up system in the state of Fig. 12, and Fig. 14 is a schematic diagram showing a cerebral blood flow measurement device attached to the back of the head.

[0067] As illustrated in FIGS. 1 to 3, a head-up system for cardiopulmonary resuscitation includes a backboard (200) on which a patient can lie, and a head-up device (100) fixed to one side of the backboard (200) where the patient's head is positioned so as to lift the head of the patient lying on the backboard (200) and then support it horizontally.

[0068] In this way, when the head-up device (100) is mounted on one side of the backboard (200), the backboard (200) has a length that can support at least the patient's chest. The preferred length of the backboard is to support the patient's chest to the buttocks while the patient's head is supported by the head-up device (100). In some cases, the backboard can be configured to support the chest or the entire body including the patient's feet. However, in order for cardiopulmonary resuscitation to be performed effectively, the backboard can be configured to have a length that supports at least the patient's head to the chest.

[0069] The backboard (200) is made of a high-strength synthetic resin material, and it is desirable to have a strength that does not break under the pressure applied during cardiopulmonary resuscitation or when the backboard (200) is used as a stretcher to move a patient. In order to reduce weight, the interior of the backboard (200) is formed as an empty space (201), and ribs (203) connecting the upper and lower parts of the backboard (200) are formed at intervals within the empty space (201) to withstand the load and pressure, so that it can sufficiently withstand the vertical load, that is, the pressure applied during cardiopulmonary resuscitation and the weight of the patient.

[0070] Meanwhile, a groove (210) is formed on one upper surface of the backboard (200).

[0071] Here, the home (210) is a seat on which the head-up device (100) is to be mounted, and the head-up device (100) is fixed to the backboard (200) with the head-up device (100) mounted on the bottom surface of the home (210). Here, the head-up device (100) will be described in detail below, and the configuration of the backboard (200) will be described in detail below.

[0072] As shown in Figures 1 to 3, the backboard (200) has a width and length that allow a patient to lie down. As previously described, the length is long enough to support the patient's chest and above while the head is placed on a head-up device (100) fixed to one side of the backboard (200), and the width is preferably wider than the patient's shoulders.

[0073] The backboard (200) configured in this manner is made of a lightweight plastic material with an empty space (201) formed inside, and ribs (203) connecting the upper and lower parts are formed at intervals inside the backboard (200) to increase resistance to vertical load.

[0074] Meanwhile, a square groove (210) is formed at a predetermined depth in the center of one side of the upper surface of the backboard (200). A head-up device (100) is mounted on the bottom surface of the square groove (210), and the base plate (160) of the head-up device (100) is fixed while mounted on the bottom surface of the groove (210).

[0075] And as illustrated in FIG. 4, a storage section (220) is formed as an empty space inside the backboard (200) outside the groove (210) with both sides of the groove (210) as the boundary, and a cover (221) is provided to cover the open upper surface of the storage section (220). The cover (221) is fixed to the backboard (200) with a piece (223) or the like while covering the upper part of the storage section (220) of the backboard (200) that is open to both sides of the groove (210). Therefore, if necessary, the cover (221) can be disassembled, and parts necessary for emergency activities or parts necessary for the operation of the head-up device (100) are positioned or fixed in the storage section (220), and then the cover (221) is reinstalled, thereby utilizing the empty space (201) inside the backboard (200) as a storage section (220).

[0076] In this way, the backboard (200) reduces the weight of the backboard (200) by forming a storage section (220) that can be opened on both sides of the home (210) to which the head-up device (100) is fixed, and at the same time, parts necessary for the operation of the head-up device (100), such as the battery, which is a power supply section (170 in FIG. 15), are positioned within the storage section (220), thereby protecting the power supply section from the external environment and reducing the components exposed to the outside of the backboard (200), thereby simplifying the appearance.

[0077] Meanwhile, although not shown in the drawing, the backboard (200) may be provided with handle grooves on both sides of the length direction so that the backboard can be carried and moved, and the upper surface of the backboard (200) may be formed into a curved surface that fits the human body structure so that the patient feels more comfortable when lying on the backboard (200).

[0078] Below, the head-up device (100) is described in detail.

[0079] As illustrated in FIG. 5, a head-up device (100) for cardiopulmonary resuscitation includes a head cover (110) that covers the back of the patient's head, neck, and both sides of the jaw, an operating unit (120) that supports the head cover (110) and moves it up and down and tilts the head cover (110) that has moved upward, a base plate (160) on which the operating unit (120) is mounted, and a power supply unit (170) that supplies power to the operating unit (120). In FIG. 5, the power supply unit (170) is illustrated as being fixed to the upper surface of the base plate (160), but as described above, it can be changed to be stored in the storage unit (220) of the backboard (200).

[0080] When the head of a patient requiring CPR is placed on the head cover (110) and the operating unit (120) is operated, the head cover (110) moves upwards so that the patient's head is positioned higher than the level of the heart. As the patient's head is positioned higher than the level of the heart in this way, cerebral perfusion pressure and cerebral blood flow can be increased. However, if the head is raised while the patient is lying flat, the patient's neck may be bent, which may block the airway or blood vessels. In other words, if the head cover (110) is tilted upwards while the patient's water purifier is positioned higher than the chin, the neck may be bent, blocking the airway or blood vessels. In this case, the tip of the head cover (110) is pressed so that the crown of the patient goes down, and the inclined head cover (110) is tilted horizontally so that the crown of the patient and the chin are level, thereby opening the patient's airway or blood vessels.

[0081] Therefore, the head-up device (100) for cardiopulmonary resuscitation according to the present invention can open the airway and blood vessels by positioning the patient's head horizontally while raising the patient's head above the level of the heart. It is configured to increase cerebral perfusion pressure and cerebral blood flow while preventing occlusion of the airway or blood vessels by performing cardiopulmonary resuscitation in this state.

[0082] Below, a head-up device configured in this manner is described in detail.

[0083]

[0084] *As illustrated in FIGS. 5 to 7, the head cover (110) of the head-up device (100) for cardiopulmonary resuscitation has a groove (111) formed on the upper surface (110H) of the head cover (110) to cover the back of the head, neck, and both sides of the jaw of a patient lying flat on his or her back. A cushion part (113) made of silicone is attached to the inside of the groove (111), so that the head of the patient placed in the groove (111) can be protected by the cushion part (113).

[0085] A chin protrusion (111P) that comes into contact with the chin on both sides is formed at the edge of the groove (111) of the head cover (110). The chin protrusion (111P) comes into contact with the chin when the patient's head is placed inside the groove (111), thereby forming an air passage between the patient's head and the groove (111). When the tip of the head cover (110) on the crown of the patient is pressed and tilted, the chin protrusion (111P) pushes up the chin area of ​​the patient, so that the head cover (110) can maintain a horizontal state as shown in FIG. 10, and in this state, the patient's airway and blood vessels are opened. The chin protrusion (111P) also has a cushion (113) attached thereto to prevent the chin from directly coming into contact with the head cover (110) made of plastic material, thereby minimizing pressure when the chin protrusion (111P) pushes up the chin.

[0086] As shown in Fig. 9, the head cover (110) includes an upper surface (110H) having a groove (111) formed therein, and a side wall (110W) extending downward from the edge of the upper surface (110H), and a curved tilting hole (115) is formed in both longitudinal side walls (110W) of the head cover (110), and a hole (117) is formed through which a first band bracket (181) for fixing a band (not shown) used to fix a patient's head passes. The tilting hole (115) and the hole (117) for the first band bracket will be described in detail later.

[0087] As shown in FIGS. 6 and 7, an operating unit (120) is positioned on the inside of a side wall (110W) formed along the perimeter of the head cover (110), and the operating unit (120) is mounted on a base plate (160). A power supply unit (170) is mounted on one side of the base plate (160) to supply power necessary for the operation of the operating unit (120), and it is preferable to mount the power supply unit (170) on the base plate (160) so as to be positioned in front of the head cover (110).

[0088] Below, the operating part (120) that moves the head cover (110) up and down is described in detail.

[0089] As shown in FIGS. 8 and 9, an operating unit (120) is mounted on the upper surface of the base plate (160), and the operating unit (120) operates by receiving power from a power supply unit (170) mounted on the base plate (160), and a head cover (110) fixed to the upper end of the operating unit (120) moves up and down according to the operation of the operating unit (120).

[0090] The operating part (120) includes a motor cylinder (121) which is a driving part whose stroke expands and contracts as the load (121R) moves forward and backward, a link part (130) which converts the expansion direction of the motor cylinder (121) into expansion in the up-and-down direction, a head cover frame (140) mounted on the upper part of the link part (130), and a tilting lock part (150) which locks the head cover frame (140) positioned horizontally as the head cover (110) is tilted.

[0091] The motor cylinder (121) is positioned longitudinally in the middle of the width of the base plate (160) so that its expansion direction is in the longitudinal direction of the base plate (160).

[0092] Two connecting bars (123) positioned vertically are mounted on both ends of the motor cylinder (121), and a link part (130) is mounted on both ends of each connecting bar (123). Here, the link parts (130) are positioned as a pair on the left and right sides of the motor cylinder (121), and the two link parts (130) on both sides are connected by the two connecting bars (123).

[0093] Therefore, the pair of link parts (130) on both sides are equally linked according to the stroke expansion of the motor cylinder (121).

[0094] More specifically, a fixed bracket (161) is fixed to the base plate (160) on the outer side of a pair of link parts (130) located on each side. Each link part (130) includes a first link (131) having one end hinged to the fixed bracket (161) and a gear part (131G) formed around the circumference of the one end, and a second link (132) having one end hinged to the other end of the first link (131) and the other end hinged to the head cover frame (140) and a gear part (132G) formed around the circumference of the other end, and a link assembly (133) in which the first link (131) and the second link (132) are combined is mounted symmetrically front-rear to form one link part (130).

[0095] Here, the hinge connecting one end of the first link (131) and the fixed bracket (161) is called the first hinge (135A), the hinge connecting the first link (131) and the second link (132) and fixed to the connecting bar (123) is called the second hinge (135B), and the hinge connecting the other end of the second link (132) and the head cover frame (140) is called the third hinge (135C).

[0096] In addition, the gear portion (131G) formed on the first link (131) meshes with the gear portion (131G) of the opposing first link (131) that is positioned symmetrically in the front-rear direction. And the gear portion (132G) formed on the second link (132) meshes with the gear portion (132G) of the opposing second link (132) that is positioned symmetrically in the front-rear direction.

[0097] Accordingly, when the stroke of the motor cylinder (121) is extended, the connecting bar (123) moves and the angle between the first link (131) and the second link (132) is rotated in a direction in which the angle between the first link (131) and the second link (132) narrows, and thus the head cover frame (140) moves downward.

[0098] When the stroke of the motor cylinder (121) contracts, the connecting bar (123) moves and the angle between the first link (131) and the second link (132) increases, and the head cover frame (140) moves upward as the first link (131) and the second link (132) rotate in the direction in which the angle between the first link (131) and the second link (132) increases.

[0099] Here, as the connecting bar (123) moves forward and backward according to the stroke of the motor cylinder (121), the link parts (130) positioned facing each other on the left and right, the meshed first links (131), and the meshed second links (132) are linked.

[0100] The head cover frame (140) is largely divided into an upper frame (141) and a vertical frame (143) located on the inner surface of the upper frame (141) and mounted on the upper frame (141).

[0101] The upper frame (141) is a structure bent at a right angle, and a head cover (110) is fixed to a horizontal surface (141H), a curved hole (145) for tilting is formed on a vertical surface (141V), and a tilting shaft (147) is mounted thereon. In addition, the vertical frame (143) faces the vertical surface (141V) of the upper frame (141), and the third hinges (135C) of the second link (132) that are mutually engaged with each other, the tilting shaft (147), and the tilting locking part (150) are mounted on the vertical frame (143).

[0102] Here, the vertical frame (143) is connected to the vertical surface (141V) of the upper frame (141) by a tilting axis (147), and thus moves up and down along the upper frame (141).

[0103] Meanwhile, the tilting locking part (150) includes a locking bolt (151) that is mounted on the vertical frame (143) by penetrating a curved hole (145) formed in the vertical surface (141V) of the upper frame (141), a nut (153) that is welded and fixed to the inside of the vertical frame (143) and is screwed to the locking bolt (151) that has penetrated the vertical frame (143), a locking flange (155) that is formed in the middle of the length of the locking bolt (151) and that presses the vertical surface (141V) of the upper frame (141) when the locking bolt (151) is tightened to fix the vertical surface (141V) and the vertical frame (143) to fix the upper frame (141) that is tilted horizontally, and a handle (157) that is fixed to the end of the locking bolt (151), and the locking bolt (151) is fixed to the head cover (110). A handle (157) is fixed to the end of a locking bolt (151) that extends outwardly through a curved tilting hole (115) formed in a side wall (110W).

[0104] Accordingly, when the stroke of the motor cylinder (121) contracts and the angle between the first link (131) and the second link (132) widens, the head cover (110) fixed to the upper frame (141) moves upward.

[0105] At this time, as shown in FIGS. 10 and 11, the head cover (110) is tilted so that the patient's neck bends forward and the patient's crown becomes high and the chin becomes low depending on the patient's height and other characteristics. In this case, the airway or blood vessels may be closed.

[0106] In this way, when the patient's neck is bent during the process of lifting the patient's head, the tip of the head cover (110) should be pressed so that the crown of the patient goes down, and the tilted head cover (110) should be tilted horizontally to open the patient's airway or blood vessel.

[0107] When the medical staff presses the tip of the head cover (110), as shown in FIGS. 12 and 13, the upper frame (141) tilted with respect to the tilting axis (147) becomes horizontal. At this time, the vertical frame (143) maintains its original vertical state regardless of the inclination of the upper frame (141) as the two third hinges (135C) are mounted and the locking bolt (151) passes through it. As the upper frame (141) tilts horizontally, the chin protrusion (111P) pushes up the patient's chin and positions the patient's crown and chin so that they are level, thereby opening the airway and blood vessels.

[0108] Meanwhile, the locking bolt (151) penetrates the vertical frame (143) and is fastened to the nut (153), and as the upper frame (141) is tilted by penetrating the curved hole (145) formed in the vertical surface (141V) of the upper frame (141) and the curved tilting hole (115) formed in the side wall of the head cover (110), the locking bolt (151) moves relatively along the holes (115, 145).

[0109] In this way, when the locking bolt (151) is tightened by rotating the handle (157) located on the outside of the head cover (110) while the upper frame (141) is tilted horizontally, as described above, the vertical frame (143) and the vertical surface (141V) of the upper frame (141) are mutually pressed, and the upper frame (141) is locked from rotating about the tilting axis (147).

[0110] By locking the upper frame (141) in a horizontal position, the patient can remain in a horizontal position from the crown to the neck, thereby opening the airway or blood vessels, and as the upper frame (141) moves upward, the patient's head is positioned higher than the heart.

[0111] Therefore, by increasing cerebral perfusion pressure and cerebral blood flow while keeping the airway or blood vessels open, the neurological prognosis of the patient can be improved.

[0112] Below, other components of the head-up device (100) for cardiopulmonary resuscitation according to the present invention are specifically described.

[0113] As illustrated in FIG. 9, the stopper (149) is fixed to the vertical surface (141V) of the upper frame (141) so as to face inwardly of the operating part (120), and as the upper frame (141) rotates around the tilting axis (147), the stopper (149) also moves up and down around the tilting axis (147). However, when the upper frame (141) is tilted, the stopper (149) moves downward and interferes with the upper surface of the second link (132), thereby preventing the upper frame (141) from being tilted at a steeper incline. This is to prevent the patient's neck from being bent excessively.

[0114] In this state, when the tip of the head cover (110) is pressed so that the upper frame (141) is positioned horizontally, the stopper (149) moves upward from the second link (132) and becomes further away.

[0115] It is preferable that a guide (137) is formed upward on the upper surface of the second link (132) to guide the movement of the stopper (149), as shown in Fig. 8.

[0116] In addition, an indicator (119) is mounted on the outside of the side wall (110W) of the head cover (110) to indicate the angle of the head cover (110) or the height from the bottom of the groove (111) of the head cover (110) to the base plate (160) using numbers or letters, and one end of an indicator piece (143B) on which an indicator (P) is formed is fixed to a vertical frame (143) and extended to the outside of the head cover (110) so that the indicator (P) is positioned toward the indicator (119).

[0117] Here, when the head cover (110) moves upward and is tilted or tilted horizontally by the medical staff, the upper frame (141) rotates around the tilting axis (147) along the head cover (110), but since the vertical frame (143) moves only up and down, the pointer (P) remains in the correct position, and the point pointed to by the pointer (P) changes as the indicator (119) rotates relatively along the head cover (110).

[0118] Accordingly, the point at which the motor cylinder (121) is maximally extended becomes the lower point of the head cover (110), and the point at which the motor cylinder (121) is maximally contracted becomes the upper point of the head cover (110). In this way, when the head cover (110) moves up and down without tilting, the upper frame (141) and the vertical frame (143) also move up and down together, so the point of the display unit (119) pointed to by the pointer (P) does not change, but when the head cover (110) is tilted, only the upper frame (141) rotates around the tilting axis (147), so the inclination of the display unit (119) also changes, and the point of the display unit (119) pointed to by the pointer (P) changes.

[0119] As described above, the display unit (119) may display the angle of the head cover (110) on the display unit (119) or display the height from the bottom of the groove (111) of the head cover (110) to the base plate (160) in numbers or letters, depending on the characteristics of the head-up device (100) that operates according to this mechanism.

[0120] Meanwhile, the band mounted on the head cover (110) fixes the patient's head so that the head does not shake during CPR while the patient's head is seated in the groove (111) of the head cover (110). To this end, the first band bracket (181) is fixed to the horizontal surface (141H) of the upper frame (141), and the first band bracket (181) extends to the outside of the side wall (110W) of the head cover (110) by penetrating the hole (117) formed in the side wall (110W) of the head cover (110). One end of the band on the first band bracket (181) is hooked to the opposite first band bracket (181) to apply pressure and fix the patient's head seated in the groove (111) of the head cover (110).

[0121] At this time, it is desirable to have a Velcro tape attached to the band so that the ends of the band can be easily attached and detached from each other.

[0122] Additionally, a second band bracket (182) is mounted on the rear end of the base plate (160), and one end of the band can be fixed to the second band bracket (182) so as to wrap around the patient's shoulder.

[0123] Meanwhile, the power supply unit (170) of the head-up device (100) for cardiopulmonary resuscitation according to the present invention described above is shown as being equipped with a battery, but instead of the battery, external power may be supplied through an external power cable to drive the operating unit (120).

[0124] In one embodiment of the head-up system described above, the head cover (110) is described as being mounted on the upper frame (141) of the head cover frame (140). In this case, since the patient's head must be accommodated within the groove (111) of the head cover (110), if the patient's head is larger than the groove (111), it becomes difficult to use the head-up system according to the present invention.

[0125] Although not shown in the drawing, the head cover can be divided into a left part and a right part, and the left head cover and the right head cover can be configured to move in a direction that is close to each other or moves away from each other.

[0126] In this case, a sliding rail that can slide left and right between the divided head cover and the horizontal surface of the upper frame is mounted so that the left head cover and the right head cover can move apart from each other along the sliding rail or move closer to each other to come into contact, and an actuator that can expand and contract the left and right head covers is mounted. Then, according to the expansion and contraction of the actuator, the left and right head covers can move apart from each other along the sliding rail or move closer to each other to come into contact. As the left and right head covers move apart in this way, the groove formed in the head covers can expand left and right to expand the range of head sizes that can be accommodated.

[0127] Here, the actuator can be the motor cylinder described above, or alternatively, a left-hand thread block is fixed to one side of the left head cover and a right-hand thread block is fixed to the other side of the right head cover, and a bolt having a left-hand thread formed on one side and a right-hand thread formed on the other side is fastened, and then the bolt is rotated by a motor or manually to move the left head cover and the right head cover apart from each other or to move them close to each other.

[0128] Meanwhile, according to an exemplary embodiment, the device may further include a cerebral blood flow measurement device (not shown), such as a near-infrared spectroscopy device, which measures the cerebral blood flow of the patient according to the height of the patient's head, and is placed in contact with the back of the patient's head. In addition, the driving unit may be controlled based on the cerebral blood flow amount of the cerebral blood flow measurement device, and for this purpose, a control unit (not shown) may be further included.

[0129] Figure 14 is a schematic diagram showing a cerebral blood flow measurement device attached to the back of the head.

[0130] As illustrated in FIG. 14, the cerebral blood flow analysis device can analyze the real-time cerebral blood flow of the patient by analyzing the cerebral blood flow signal received from the test patch (I) mounted on the patient's head (H). At this time, the cerebral blood flow analysis device can analyze the cerebral blood flow using near-infrared spectroscopy (NIRS). However, the embodiment is not limited thereto, and the cerebral blood flow analysis device may measure the cerebral blood flow of the patient using any other appropriate method according to the embodiment. In addition, the cerebral blood flow analysis device may use a micro LED (Light Emitted Diode) to obtain an improved cerebral blood flow signal of the patient, but the embodiment is not necessarily limited thereto.

[0131] In a non-limiting example, the test patch can be attached to the patient's skin to acquire cerebral blood flow signals. For example, the test patch can be attached to the patient's forehead or the back of the head. Preferably, the test patch is attached to the back of the patient's head, which provides a better attachment environment compared to attaching the patch to the forehead due to the weight of the patient's head, thereby enabling more effective acquisition of the patient's cerebral blood flow signals.

[0132] Meanwhile, the head-up device for cardiopulmonary resuscitation can control the driving unit according to the operation mode of the control unit to adjust the height of the patient's head, and can measure the patient's real-time cerebral blood flow accordingly.

[0133] The target cerebral blood flow may be, for example, 1.15 times the patient's real-time cerebral blood flow when the angle between the patient's back and the patient's head is 0 degrees. However, the embodiment is not limited thereto, and the target cerebral blood flow may vary depending on the embodiment.

[0134] More specifically, the real-time cerebral blood flow of the patient can be measured in a state where the patient's head height is positioned at an arbitrary position according to the operation mode of the control unit.

[0135] Next, a height satisfying a predetermined condition according to the operation mode of the control unit can be searched for. For example, a height satisfying a predetermined condition according to the first mode of the control unit or a predetermined condition according to the second mode can be searched for.

[0136] Next, the operation of the driving unit can be stopped at a height that satisfies a predetermined condition.

[0137] Meanwhile, in the first mode, the control unit can gradually increase the patient's head height. For example, the control unit can gradually increase the height from the minimum value of a preset range. However, the embodiment is not limited thereto, and the control unit can also gradually increase the height from other values.

[0138] Next, the control unit can measure the patient's real-time cerebral blood flow at gradually increasing heights. The control unit can then determine whether the patient's real-time cerebral blood flow is greater than the aforementioned target cerebral blood flow. If the patient's real-time cerebral blood flow is less than the aforementioned target cerebral blood flow, the control unit can control the actuator to further increase the head height. If the patient's real-time cerebral blood flow is greater than the aforementioned target cerebral blood flow, the control unit can control the actuator to fix the head height.

[0139] Meanwhile, in the second mode, the control unit can adjust the height of the patient's head to correspond to a preset height. Subsequently, the control unit can measure the patient's real-time cerebral blood flow at multiple preset points. The control unit can then search for the height at which the increase in cerebral blood flow is greatest among the patient's real-time cerebral blood flow at each of the multiple height points. Subsequently, the control unit can control the actuator to be fixed at the height at which the increase in cerebral blood flow is greatest.

[0140] Meanwhile, in the head-up system for cardiopulmonary resuscitation according to the present invention illustrated in FIGS. 5 to 7, cardiopulmonary resuscitation is performed by raising and tilting the patient's head using a head-up device (100) to open the airway and blood vessels, and since a solid backboard (200) supports the patient's chest from below, the pressure applied downward from the upper part of the chest is not absorbed by the backboard (200) but is effectively applied to the heart.

[0141] Therefore, it can increase the survival rate through CPR by reducing the loss of pressure and increasing the effectiveness of CPR.

[0142] In addition, although not shown in the drawing, handle grooves can be formed in the longitudinal direction on both sides of the backboard (200) to facilitate easy gripping and movement during emergency activities.

[0143] Meanwhile, the head-up system for cardiopulmonary resuscitation according to the present invention described above is configured so that the cover (221) of the backboard (200) is detachable, and the cover (221) can be attached and detached to the backboard (200) by a piece (223), etc. However, in some cases, as shown in FIG. 15, the cover (221) can be hinged to the backboard (200) body and rotated to open or close the storage portion (220) by fastening and releasing the fastening.

[0144] In the drawing, Fig. 15 is a cross-sectional view of a backboard for showing a storage section as a modified example of the backboard shown in Fig. 2.

[0145] As illustrated in Fig. 15, the storage section (220) of the backboard (200) is opened and closed by a cover (221). One side of the cover (221) is hinge-connected to the outer wall (225) of the storage section (220) of the backboard (200) and pivots around the hinge point (230) to open or close the storage section (220). An elastic protrusion (228) is formed on one side of the cover (221) configured in this manner, and a protrusion groove (229) is formed on the inner wall (226) of the storage section (220) to correspond to the elastic protrusion (228) when the cover (221) closes the storage section (220).

[0146] Accordingly, when the cover (221) is rotated to cover and close the storage portion (220), the elastic protrusion (228) aligns with the protrusion groove (229) and the cover (221) is fastened to the backboard (200). Afterwards, when the user widens the space between the inner wall (226) where the protrusion groove (229) is formed and the cover (221), the elastic protrusion (228) is released from the protrusion groove (229) and the cover (221) can be rotated. At this time, the cover (221) can be configured to be rotated to open the storage portion (220).

[0147]

[0148] The head-up system including a backboard according to the present invention and the control method thereof improve the neurological prognosis of the patient by tilting the patient's head horizontally while positioning the patient's head higher than the heart to open the airway and blood vessels so as to increase cerebral perfusion pressure and cerebral blood flow during cardiopulmonary resuscitation, and furthermore, stably supporting the patient's head so as not to shake during cardiopulmonary resuscitation, and thus has industrial applicability.

[0149] In addition, the present invention has sufficient industrial applicability because it is configured to enable a patient to assume a stable head-up position, measure the patient's cerebral blood flow in real time to perform precise emergency treatment, and prevent pressure from being absorbed and reduced so that the pressure applied to the chest can be smoothly transmitted to the heart when performing cardiopulmonary resuscitation while tilting the patient's head horizontally to open the airway and blood vessels.
