Description

[0001] Automated Cardiopulmonary Resuscitation Device

[0002] Technical Field

[0003] The invention relates to a mechanical cardiopulmonary resuscitation (CPR) device used in high-traffic areas such as hospitals, ambulances, public spaces, gyms, shopping malls, stadiums, and airports.

[0004] The invention particularly relates to a cardiopulmonary resuscitation (CPR) device that provides an effective emergency response in cases of sudden cardiac arrest by automatically and continuously applying CPR to maintain the patient's vital functions, while also continuously monitoring the patient's vital parameters through integrated sensors.

[0005] State of Art

[0006] Mechanical CPR (cardiopulmonary resuscitation) devices ensure that chest pressures are performed effectively with sufficient depth and speed, without being affected by human factors or the transport environment, and without complications during pressures. There are various devices that have been developed to serve this purpose.

[0007] Current cardiopulmonary resuscitation (CPR) devices used in the state of the art can only be used under the supervision of a healthcare professional. Therefore, these devices are not suitable for providing first aid to citizens who are present in crowded areas such as public spaces, gyms, and shopping malls and who are unaware of how the device works, in the event of a possible cardiac arrest.

[0008] The cardiopulmonary resuscitation (CPR) devices in the state of the art can only perform pressures. These devices cannot monitor crucial data such as the patient's ECG, pulse rate, and oxygen saturation. This situation prevents the CPR process from being carried out more effectively. Current cardiopulmonary resuscitation (CPR) devices are unable to monitor when an individual needs CPR. Because they lack a system to prevent unnecessary cardiopulmonary resuscitation (CPR) in healthy individuals, its use outside of hospitals poses a danger. Current cardiopulmonaryresuscitation (CPR) devices do not have a feature that allows the part of the device that applies chest pressures to be positioned towards the patient's sternum. However, placing chest pressures in the correct location— that is, the lower third of the patient's sternum — is crucial for the effectiveness of chest pressures. With the present art, the devices used have no mobility if they are not positioned correctly on the patient, so the patient must be repositioned to achieve the correct position. However, the time lost during this process is detrimental to the patient's life and prevents the maintenance of the continuous cardiopulmonary resuscitation (CPR) necessary for its success.

[0009] In one of the devices currently in use, after the patient is placed on the backrest of the device, the upper part is attached, and after hearing a click sound, it is ensured that the device is connected. Because the device's pressure point is fixed, the upper and lower parts of the device do not lock together properly in very large patients, rendering the device unusable. Even the instruction manual for the device states that in very large patients, the upper part of the device may not lock onto the lower part, and therefore manual pressures should be continued. Another device's user manual includes a section on " patients suitable for treatment" in its specifications, stating that the device will only be suitable for patients with a maximum chest width of 17.5 inches (44.4 cm) and a chest height between 7.4 and 12.7 inches (18.8 and 32.3 cm). Therefore, it is not possible to perform the procedure on patients who are very large, obese, or whose anatomy is not suitable for the device. This situation demonstrates that current mechanical CPR devices have difficulty adapting to anatomical differences.

[0010] In the research carried out in the literature, the document numbered WO2017158451 can be cited as an example of the known state of the art. The said document describes a chest pressure device used to perform cardiopulmonary massage on a patient's chest, positioned on a support board. The device is secured by means of at least three clamping elements that pass through the desired contact area and its surroundings.

[0011] As a result, the existence of the above-mentioned problems and the inadequacy of current solutions have made it necessary to develop a new approach in the relevant technical field.Purpose of the Invention

[0012] The invention relates to an automated cardiopulmonary resuscitation device that eliminates the aforementioned disadvantages and introduces new advantages to the relevant technical field.

[0013] The main purpose of this invention is to provide a cardiopulmonary resuscitation (CPR) device that provides effective emergency intervention in cases of sudden cardiac arrest by automatically and continuously performing CPR on the patient, thereby maintaining their vital functions.

[0014] The purpose of this invention is to provide a device for cardiopulmonary resuscitation (CPR), a critical life-saving procedure in cases of sudden cardiac arrest, that can be performed without being affected by external factors such as personnel errors, fatigue, lack of strength, or loss of time.

[0015] Another purpose of the invention is to provide a cardiopulmonary resuscitation (CPR) device that, in addition to applying standard pressures, allows for continuous monitoring of the patient's vital signs such as ECG, pulse rate, and oxygen saturation, thus enabling effective CPR procedures.

[0016] Another purpose of the invention is to provide a cardiopulmonary resuscitation (CPR) device that can be used by both healthcare professionals and citizens without intervention knowledge, thanks to its interactive information system equipped with artificial intelligence and its color touch screen that monitors vital sign data from the patient.

[0017] Another purpose of the invention is to provide a cardiopulmonary resuscitation (CPR) device that monitors the patient's vital signs in real-time and, during CPR, pauses for 5-6 seconds every 2 minutes to determine if the heart has started beating again, thereby stopping the CPR when successful heart restart and preventing unnecessary chest pressures.

[0018] Another purpose of the invention is to provide a cardiopulmonary resuscitation device which, thanks to the sliding system it incorporates, allows the pressure tip to move in all directions and enables said pressure tip, with its wide range of motion in alldirections, to be positioned on the lower one-third of the patient’s sternum in accordance with standards; thereby preventing the practice used in existing techniques of positioning the patient according to the device, i.e., changing the patient’s position, and allowing the pressure tip to be adjusted and fixed so as to correspond to the lower one-third of the patient’s sternum without loss of time and without changing the patient’s position.

[0019] In order to achieve all of the purposes stated above and those that may arise from the detailed description, the invention is a cardiopulmonary resuscitation device used in locations with high human traffic such as hospitals, ambulances, public areas, gyms, shopping malls, stadiums, and airports, which provides effective emergency intervention in cases of sudden cardiac arrest by applying automatic and continuous cardiopulmonary resuscitation to maintain the patient’s vital functions, comprising a base plate forming a back support placed under the patient to be treated, a foldable right arm located on the right side of the base plate, a right opening handle on the right arm that enables folding of the right arm, a battery connected to the device body that allows the cardiopulmonary resuscitation device to operate continuously throughout the cardiopulmonary resuscitation, and a silicone pressure tip connected to the underside of the device body via a pressure tube, which performs chest pressures throughout the cardiopulmonary resuscitation applied by the device by being adjustable in height according to the patient’s physical characteristics through the up- and-down movement of the pressure tube, comprising the following:

[0076] Detailed Description of the Invention

[0077] In this detailed description, the preferred alternatives to the cardiopulmonary resuscitation device, which is the subject of this invention, are described only for the purpose of better understanding the subject and without forming any limiting effect.

[0078] Figures 1 and 2 show the appearance of the cardiopulmonary resuscitation device, which is the subject of this invention. Accordingly, the CPR device, in its most basic form, comprises a lower table (8), which forms the back piece placed under the patient to be operated on, and a foldable right arm (3) located on the right side of the lower table (8), a right opening handle (4) on the right arm (3) which enables the right arm (3) to be folded, a foldable left arm (5) located on the left side of the lower table (8) and holding the device body (1) between the right arm (3), the left opening handle (6) on the left arm (5) which enables the folding of the left arm (5), a battery (7) which is connected to the device body (1) and enables the cardiopulmonary resuscitation device to work continuously during cardiopulmonary resuscitation, a silicone pressure tip (19) that is connected to the bottom of the device body (1 ) via a pressure pipe (18) and performs chest pressures during the cardiopulmonary resuscitation applied by the device by adjusting the length according to the physical characteristics of the patient by moving the pressure pipe (18) up and down, a chassis (9) located inside the device body (1) to enable the silicone pressure tip (19) to move in all directions on both axes, a horizontal shaft (20) and a vertical shaft (21) connected to the chassis (9) and free-moving linear bearing (23) located on the horizontal shaft (20) and vertical shafts (21), a sliding system table (22) connected to linear bearings (23), a pressure system lower table (15) connected to linear bearings (23) and passing the pressure pipe (18) through it, a step motor (12) connected to the front sliding system table (22) by step motor stabilizer (25), a belt pulley system (10) driven by the step motor (12), a motor stabilizing platform (11) which ensures that the step motor (12) and the belt pulleysystem (10) stay together in a fixed way, a trapezoidal shaft (16), which is fixed to the pressure pipe (18) by being connected to the belt pulley system (10) and enables the up and down movement of the pressure pipe (18) and the silicone pressure tip (19) together with the pressure pipe (18) by the rotational movement of the step motor (12), a trapezoidal nut (17), which is located on the trapezoidal shaft (16) and remains fixed during the rotational movement of the trapezoidal shaft (16), assists in the up and down movement of the silicone pipe (18), a linear shaft (14) located on both sides of the pressure pipe (18), the linear system platform (13) which keeps the linear shafts (14) together, the pulley (27) located at the end of the step motor (12), a pulley belt (28), which is connected to the pulley (27) and enables the silicone pressure tip (19) to move in the right and left directions by means of the rotational movement of the step motor (12), an idler pulley (24) that is connected to the pulley belt (28) by means of the pulley holder (26) located under the linear bearings (23), ECG probe inlet hole (29) that is located on the device body (1) and allows ECG probe connection cable (33), which connects ECG bands and the device body (1), to enter the device body (1), the pulse oximeter probe inlet hole (30) that is located on the device body (1) and allows the pulse oximeter probe connection cable (34), which provides a connection between the pulse oximeter and the device body (1), to enter the device body (1), the ECG sensor (31) located on the device body (1) that enables the measurement of the electrical activity of the patient’s heart and the recording of this data by displaying it, the pulse oximeter sensor (32) that is located on the device body (1) and measures the patient's oxygen saturation.

[0079] The cardiopulmonary resuscitation device, which is the subject of the invention, has right opening handles (4) and left opening handles (6) on the inside of the right arm (3) and left arm (5), as shown in Figures 3 and 4. When the right opening handle (4) and the left opening handle (6) are pulled, the right arm (3) and the left arm (5) fold closed.

[0080] As shown in Figure 6, the horizontal shaft (20) and the vertical shaft (21 ) are connected to the chassis (9), which is located inside the device body (1) and is shown in Figure 5. The horizontal shaft (20) and the vertical shaft (21 ) pass through the linear bearings (23). The sliding system tables (22) and the pressure system lower table (15) are connected through the connectien holes on the linear bearings (23). Linear bearings (23) can move freely on the horizontal shaft (20) and the vertical shaft (21).There is one step motor (12) on the front sliding system table (22). This step motor (12) is fixed to the front sliding system table (22) with a step motor stabilizer (25). There is a pulley (27) at the end of the step motor (12). The pulley belt (28) is attached to this pulley (27). After passing over the pulley (27), this belt (28) is connected to the idler pulleys (24) which are fixed on the chassis (9). As the step motor (12) rotates, the pulley (27) rotates and pulls the belt (28). This enables the silicone pressure tip (19) to move to the right and left. When the step motor (12) is not moving, the silicone pressure tip (19) remains fixed in its position.

[0081] The cardiopulmonary resuscitation device described in the invention has a silicone pressure tip (19) that applies pressure to perform an effective cardiopulmonary resuscitation procedure. The silicone pressure tip (19) is connected to a pressure pipe (18). The length of the pressure tip (19) can be adjusted and fixed to suit the characteristics of the person to be pressured.

[0082] At the end of the step motor (12) there is a small pulley which is part of the belt pulley system (10). As the small pulley on top of the step motor (12) in the belt pulley system (10) rotates, it also rotates the other large pulley in the belt pulley system (10). When the large pulley in the belt pulley system rotates, the trapezoidal shaft (16) also rotates. While the trapezoidal shaft (16) rotates, the trapezoidal nut (17) attached to it is fixed and therefore cannot rotate. Thus, the pressure pipe (18) and the silicone pressure tip (19) attached to the pressure pipe (18) can move up or down. Thanks to this operating principle, the cardiopulmonary resuscitation device can adapt to the chest height of the patient receiving pressures, allowing for rapid intervention without wasting time.

[0083] The cardiopulmonary resuscitation device has an ECG sensor (31) on the device body (1) to measure the electrical activity of the patient's heart and to record this data by displaying it. The ECG sensor (31) on the device body (1) is a 3-way sensor system. In order to measure ECG data while using the cardiopulmonary resuscitation device, one electrode is attached to the patient's right arm, one to the left arm and one to the abdominal area. With the help of these electrodes, the patient's ECG data is measured. The ECG data obtained from the patient is monitored by the cardiopulmonary resuscitation device by being displayed on the LCD display (2) on the device body (1) and diagnoses such as VT (ventricular tachycardia), VF (ventricular fibrillation), sinus rhythm, asystole, pulseless electrical activity are shown on the LCD display (2) with the developed algorithm. The ECG sensor (31) on thedevice body (1 ) sends the ECG data received from the patient through the ECG probe inlet hole (29) on the device body (1), and allows the user to manage a CPR process in which the patient's condition can be monitored.

[0084] The device body (1) contains a pulse oximeter sensor (32) which allows the patient's blood oxygen saturation and pulse rate to be measured and monitored and the patient's saturation to be tracked. When using the cardiopulmonary resuscitation device, the pulse oximeter is attached to the patient's fingertip. The aforementioned pulse oximeter sensor (32) performs its function by sending the measured data through the pulse oximeter probe inlet hole (30) to the microcontroller inside the device body (1).

[0085] The LCD display (2) located on the device body (1) enables the monitoring and visualization of data coming from the patient. Accordingly, preferably a 10.1 -inch LCD display (2) is touch-sensitive, high brightness and resolution and color; it allows the user to perform a comfortable CPR intervention. The LCD display (2) that monitors the data displays the start and stop icons, the patient's ECG graph, the patient's oxygen saturation, the patient's pulse rate, the number of compressions the device applies to the patient, the time, the charge indicator, and the CPR duration information. The LCD display (2) that monitors the data displays the start and stop icons, the patient's ECG graph, the patient's oxygen saturation, the patient's pulse rate, the number of compressions the device applies to the patient, the time, the charge indicator, and the CPR duration information. Thanks to this monitoring system, vital data obtained from the patient via sensors and details of the emergency intervention applied by the device can be displayed in a way that facilitates user operation. If the cardiopulmonary resuscitation device determines that the ECG data received from the patient is normal, it issues a "do not apply pressure" warning. It alerts the user to avoid unnecessary pressure. However, if compressions are still required, pressing the "start" icon on the warning screen that appears will restart and continue the chest compressions.
