Description

portable cardiopulmonary resuscitation device

The disclosure below relates to a portable cardiopulmonary resuscitation device.

CPR is an essential first aid measure when the heart stops functioning or stops. If no action is taken quickly, brain damage begins after 4 minutes and serious damage occurs to other vital organs, and survival rate drops sharply after 10 minutes. Normally, the survival rate decreases by 7-10% for each minute that defibrillation is delayed, but it is known to decrease by 2.5-5% when CPR is performed. If CPR is performed appropriately, the survival rate significantly improves. However, even trained people often become embarrassed when faced with CPR and are unable to perform CPR properly.

According to the latest cardiopulmonary resuscitation guidelines, a speed of more than 100 beats per minute is maintained at a depth of at least 5 cm and an appropriate cardiac output is maintained through sufficient relaxation between compressions, thereby improving coronary artery pressure, increasing the possibility of recovery of spontaneous circulation, and protecting the brain, lungs, etc. In order to reduce damage to vital organs, a system is needed to explore optimal CPR and provide continuous chest compressions without fatigue.

In one embodiment, the second connection frame 120 may be connected to the fixed frame 130 through the second connection portion 121. For example, a connecting rod that is inserted and fastened to the second insertion portion of the fixing frame 130, which will be described later, may be formed in the second connecting portion 121.

In one embodiment, each of the first connection frame 110 and the second connection frame 120 changes the state of the portable cardiopulmonary resuscitation device 1 to the first state or the second state through a rotation motion with respect to the main body 100. It can be changed to . In one embodiment, the first connection frame 110 and the second connection frame 120 have a first connection part 111 and a second connection part 121 located on the lower side of the main body 100 and a fixed frame ( 130) may be rotated with respect to the main body 100 so as to be in a first state (e.g., FIG. 2) that can be combined with the main body 100. In one embodiment, the first connection frame 110 and the second connection frame 120 are connected to a second connection frame in which the first connection part 111 and the second connection part 121 are located on the upper side of the main body 100. It can be rotated with respect to the main body 100 to achieve a state (eg, Figure 4).

In one embodiment, the first connection frame 110 and the second connection frame 120 may be connected to the fixed frame 130 in the first state of the portable CPR device 1. In this case, the main body 100, the first connection frame 110, the second connection frame 120, and the fixing frame 130 may form a seating space where the body of the patient (P) can be located. there is. For example, the portable cardiopulmonary resuscitation device 1 may surround the body of the patient P around the seating space.

For example, gripping grooves that can be gripped by a user's hand may be formed at the ends of the first connection frame 110 and the second connection frame 120.

In one embodiment, the distance between the first connection frame 110 and the second connection frame 120 may vary depending on the rotation state of the main body 100. In one embodiment, the first rotation axis A1 and the second rotation axis A2 may form an intersection on the lower side of the main body 100. For example, the first rotation axis A1 along which the first connection frame 110 rotates with respect to the main body 100 may be inclined to the ground (eg, XY plane). In this case, the first rotation axis A1 may be inclined upward with respect to the ground from the main body 100 toward the first connection frame 110. The second rotation axis A2 along which the second connection frame 120 rotates with respect to the main body 100 may be inclined to the ground. In this case, the second rotation axis A2 may be inclined upward with respect to the ground from the main body 100 toward the second connection frame 120. In this case, the distance between the first connection frame 110 and the second connection frame 120 may be closer when the portable CPR device 1 is in the second state than when it is in the first state. In one embodiment, the first connection frame 110 and the second connection frame 120 may have a streamlined shape bent along each longitudinal direction. For example, the distance between the first connection frame 110 and the second connection frame 120 increases as it moves away from the main body 100, based on the first state as shown in FIG. 2, and then the first connection part It may be formed in a shape that is close to (111) and the second connection portion (121). In this case, the first connection part 111 and the second connection part 121 may form a minimum gap in the second state of the portable CPR device 1. In another embodiment, the first rotation axis A1 and the second rotation axis A2 may coincide with each other or may be parallel to each other. In this case, the first connection frame 110 and the second connection frame 120 may have a shape bent along the longitudinal direction so that the user can easily hold the portable CPR device 1 in the second state.

In one embodiment, the fixing frame 130 may be detachably coupled to the first connection frame 110 and the second connection frame 120. For example, the fixing frame 130 is placed on the ground in the first state of the portable cardiopulmonary resuscitation device 1 and both ends are fastened to the first connection portion 111 and the second connection portion 121, respectively, thereby creating a seating space. The back of the patient (P) located at can be supported. The fixed frame 130 is fastened to the first connection part 111 and the second connection part 121, and the first connection frame 110, the second connection frame 120, and the main body 100 are placed on the ground. It can play the role of a support that allows it to be erected. A support portion 131 to comfortably support the body of the patient P may be formed on the surface of the fixing frame 130, for example, an area in contact with the body of the patient P. The support portion may be formed of a material such as, for example, a compressible material, sponge, or rubber. In one embodiment, the fixing frame 130 is connected to the first connection frame 110 and the second connection frame 120 as shown in FIG. 3 during the process of converting the portable cardiopulmonary resuscitation device 1 from the first state to the second state. ) can be separated from.

In this way, when the fixing frame 130 is separably fastened to the first connection frame 110 and the second connection frame 120, CPR for an unconscious patient (P) can be more easily implemented. . For example, when the portable CPR device (1) is used on an unconscious patient (P), the fixation frame (130) is first placed on the ground, and then the patient (P) is placed on the upper surface of the fixation frame (130). , For example, it can be positioned as a support part, and the first connection frame 110 and the second connection frame 120 can be coupled to the fixed frame 130 so that the patient P can be positioned in the seating space. In one embodiment, the fixation frame 130 overlaps the compression module 140 for compressing the chest of the patient (P) when viewed in the first direction (e.g., Z-axis direction), so the fixation frame 130 is It can also function as an indicator to position the patient's (P) chest area for chest compressions.

For example, as shown in FIGS. 2 to 4, the rotational movement of the first connection frame 110 and the second connection frame 120 with respect to the main body 100, and the first connection frame 110 and the second connection frame 120 Through the fastening operation of the fixing frame 130 to the connection frame 120, the state of the portable cardiopulmonary resuscitation device 1 can be changed quickly and easily.
