Description

Cardiopulmonary resuscitation device with detachable support plate and support leg}

The present invention relates to a cardiopulmonary resuscitation device in which a hood support plate and support are detachable, and more particularly, a support plate coupled with a hood for cardiopulmonary resuscitation is detachable from a support plate supporting a patient's back. It is about a possible CPR device.

Various types of devices for cardiopulmonary resuscitation (CPR) are known in the prior art. One such device is powered by compressed air or breathing gas (Jolife AB, Lund, Sweden; LucasTM). As a unique advantage of the cardiopulmonary resuscitation device, it is possible to transport due to its low weight. Another advantage is the elastic nature of compressed air, whereby gas-powered CPR devices cause less damage to the patient's chest than devices equipped with rigid compression means. The known device can be used as an emergency facility in a life-saving situation. In addition, the known device may be supplied with drive gas from a hospital air supply line, which may be desirable for uninterrupted blows of CPR when a patient is hospitalized.

However, in the case of the general public, even if they have been trained in CPR, there is a problem in that it is difficult to accurately determine the depth of compression due to the unfamiliarity of CPR and the burden of rib damage and the inconsistent chest height for each patient in the event of cardiac arrest.

In addition, the conventional cardiopulmonary resuscitation device must have a support plate formed so that the patient can lie down, resulting in spatial restrictions in CPR, and as it is impossible to attach and detach the chest compression component and airway securing component from the support plate, the support plate is placed (or installed) There was a problem that cardiopulmonary resuscitation could be performed only in the designated place.

On the other hand, as devices for cardiopulmonary resuscitation different from the prior literature, US Patent No. 9,107,800 (title of invention: front part for support structure for CPR) and US Patent No. 10,292,901 (name of invention: managing cardiopulmonary resuscitation) support structure) has been published.

In the prior literature, there is a possibility that the fastening part of the support is closed without the knowledge of the user who provides CPR to the patient, and in this way, when the user tries to fasten the fastening part and the back plate without recognizing the closed state of the fastening part There was a problem that caused a time delay in an emergency situation due to a failure in fastening.

In addition, the prior art documents accept the shaft in the form of a claw and have a form with a free space wider than the diameter (thickness) of the shaft in order to easily accept the shaft. Due to the free space between the chest compression and release, the support and support plate vibrate up and down and noise (noise) is generated, causing a phenomenon that interferes with the communication of medical staff at the emergency site. There was a problem that damage and the like occurred.

In addition, in the prior literature, the user operated the fastening device between the support and the base plate, but in a situation where the support of the CPR device placed between the torso and arm of a large patient or an item around the cardiopulmonary resuscitation device applied to the patient was placed, the support There was a problem in that the separation of the support plate and the support plate was not clearly recognized by the medical staff, which caused a time delay in an emergency.

In one embodiment of the present invention, the CPR device may further include a sensor 500 for detecting information during a patient's emergency treatment process, and the sensor 500 includes a first detection sensor 520 and a second detection sensor 500. It may be made of a sensor 530.

6 is a view showing a sensor provided in the CPR device according to an embodiment of the present invention.

Referring to FIG. 6, the sensor 500 detects the current position of the piston 310 in real time through the first sensor 520 and the second sensor 530 to generate current position information, and the piston ( Current location information of 310 is transmitted to the control unit 320 in real time.

Meanwhile, the control unit 320 controls the operation of the piston 310 using the information of the first detection sensor 520 and the second detection sensor 530 before analyzing the patient's heart rhythm. An example of a process of controlling the operation of the piston 310 using current position information of is as follows.

The control unit 320 moves the lower end of the piston 310 to the chest compression start position so that the lower end of the piston 310 does not come into contact with the patient's chest before the patient's heart rhythm is analyzed, and the lower end of the piston 310 When moving to this chest compression start position, it is determined whether the current position information of the piston 310 received in real time matches the chest compression start position, and the lower end of the piston 310 is disposed relatively higher than the chest compression start position. By doing so, the piston 310 is in a standby state before compressing the patient's chest compression point.

In addition, the control unit 320, after analyzing the patient's heart rhythm, controls the piston ( 310) can be controlled.

And before the piston 310 compresses and relaxes the patient's chest compression point, the control unit 320 compresses the patient's chest when the piston 310 descends as much as the chest compression depth set through the compression depth setting button. In order to do so, the distance between the lower end of the piston 310 and the patient's chest considers a predetermined distance (eg, 0 to 2 cm). That is, the patient's chest compression start position means the position of the piston 310 to be placed for chest compression of the patient during compression and relaxation of the patient's chest.

In addition, the control unit 320 optimizes the patient's chest compression start position in one embodiment at regular intervals (eg, 2 minutes and 30 seconds after completing the chest compression mode, chest compression depth, and number of chest compressions). It can be achieved by updating the chest compression start position. In this way, updating the patient's chest compression start position at regular intervals is when the chest is depressed through chest compression and relaxation of the patient or when the patient supports the back on the support plate 100. This is because the patient is moved during the process, so the patient's chest compression start position may not be optimized.

The control unit 320 receives electrical information (eg, power) used from a motor for driving the piston 310 and current position information of the piston, so that when a change in the patient's chest compression start position is detected, the patient The chest compression start position can be updated.
