Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly relates to an electric shock first-aid device for the intensive care unit. Background Art

[0002] The defibrillator is one of the commonly used electric shock first-aid devices in the intensive care unit. It is a medical device that uses a strong pulsed current to pass through the heart to eliminate arrhythmia and restore normal sinus rhythm. In the intensive care unit (ICU), when an emergency such as cardiac arrest occurs to a patient, the defibrillator can quickly and accurately take emergency measures to restore the normal rhythm of the heart, thereby saving the patient's life.

[0003] Currently, the defibrillators on the market are mainly used for electric shock defibrillation of patients with cardiac arrest to restore normal heart rhythm. However, after the defibrillation operation is completed, medical staff need to perform operations such as external chest compressions on the patient, resulting in insufficiently rapid connection of operations during the first-aid process and easily wasting precious first-aid time. Moreover, in the existing defibrillation operation, the electrode plates need to be smeared with conductive paste to ensure good electrical conductivity. The existing conductive paste smearing methods are mostly manual smearing, which has problems such as uneven smearing, difficult control of the smearing amount, and easy contamination.

[0004] Therefore, the present application provides an electric shock first-aid device for the intensive care unit to meet the needs. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide an electric shock first-aid device for the intensive care unit to solve the above technical problems. The present invention provides the following technical solutions:

[0011] Optionally, a display screen is provided on the side of the central control machine for displaying the electrocardiogram signal of the patient.

[0016] Optionally, the cardiopulmonary resuscitation control module includes a cylinder driving circuit, a pressing depth and frequency monitoring circuit, and a voice prompt and alarm circuit.

The shaft of the driving cylinder 8 is vertically downward and fixed with a suction cup 9. Specifically, a fixed disk 801 is fixed to the lower end of the shaft of the driving cylinder 8, and the suction cup 9 is connected to the lower end surface of the fixed disk 801 through an elastic member 802.

[0045] As Figure 8 shown, a heart rhythm detection and judgment module 10, a defibrillation control module 11, and a cardiopulmonary resuscitation control module 12 are provided in the central control machine 2. The heart rhythm detection and judgment module 10 can adopt but is not limited to a high-precision electrocardiogram sensor, a signal amplification and filtering circuit, and a microcontroller, and is used to collect the electrocardiogram signal of the patient and analyze and judge the collected electrocardiogram signal; the defibrillation control module 11 includes a high-voltage generator and is used to perform high-voltage electric pulse defibrillation on the patient through the electrode plate 3; the cardiopulmonary resuscitation control module 12 is used to control the driving cylinder 8 to drive the suction cup 9 to perform external chest compression operations on the patient after the defibrillation operation of the defibrillation control module 11 is completed and when the heart rhythm detection and judgment module 10 detects that the patient's heart rhythm has not returned to normal and meets the cardiopulmonary resuscitation conditions.

[0046] A limit jack 501 is opened at the top of the lifting column 5. A movable cylinder 6 is vertically slidably installed in the limit jack 501. A vertical screw rod 502 is rotatably installed in the middle of the limit jack 501. The top end of the screw rod 502 threadedly penetrates through the top of the movable cylinder 6 and is fixed with a handle 503.

[0047] A threaded hole 601 for the screw rod 502 to penetrate through is opened in the middle of the movable cylinder 6. One end of the movable frame 7 is horizontally rotatably installed on the top of the movable cylinder 6.

[0048] In this embodiment, the defibrillation control module 11 further includes an energy selection and control circuit, which is connected to the GPIO pin of the microcontroller and is also connected to the energy adjustment element inside the high-voltage generator, and is used to enable the microcontroller to adjust the defibrillation energy by controlling the energy selection and control circuit according to the patient's physical factors.

[0049] The cardiopulmonary resuscitation control module 12 includes a cylinder drive circuit, a pressing depth and frequency monitoring circuit, and a voice prompt and alarm circuit. Among them:

[0050] The input end of the cylinder drive circuit is connected to the GPIO pin of the microcontroller, and the output end is connected to the solenoid valve for driving the cylinder; the pressing depth and frequency monitoring circuit includes a pressure sensor and a displacement sensor, the pressure sensor and the displacement sensor are installed on the suction cup 9, and the output ends of the pressure sensor and the displacement sensor are connected to the analog input pins of the microcontroller; the control end of the voice prompt and alarm circuit is connected to the GPIO pin of the microcontroller.

[0051] The working process of the technical solution provided by the present invention is as follows:

[0052] When the intensive care unit electric shock first aid device is in use, the central control machine 2 is started, and the device performs self-check. The electrode plate 3 is taken out from the storage box 4. During this process, the roller 403 will automatically evenly apply the conductive paste on the electrode plate 3, so that the electrode plate 3 can make good contact with the appropriate position on the patient's body surface.

[0053] Subsequently, the heart rhythm detection and judgment module 10 collects the patient's electrocardiogram signal through the electrode plate 3. After processing and analysis, the result is transmitted to the central control machine 2. If the heart rhythm detection and judgment module 10 determines that the patient needs defibrillation, the central control machine 2 sends an instruction to the defibrillation control module 11. The energy selection and control circuit in the defibrillation control module 11 adjusts the defibrillation energy according to the relevant information of the patient, and the high-voltage generator generates high-voltage electrical pulses to perform electric shock defibrillation on the patient through the electrode plate 3. At the same time, the contact detection circuit between the defibrillation electrode and the patient monitors the contact situation in real time.

[0054] After defibrillation is completed, if the patient's heart rhythm has not returned to normal and meets the conditions for cardiopulmonary resuscitation, the cardiopulmonary resuscitation control module 12 is activated. Medical staff can first adjust the position of the suction cup 9 through the lifting column 5, the movable cylinder 6, and the movable frame 7 to accurately align it with the patient's chest. Then, the cardiopulmonary resuscitation control module 12 controls the driving cylinder 8 to drive the suction cup 9 to perform external chest compression operations. During the compression process, the compression depth and frequency monitoring circuit monitors the data in real time and feeds it back to the central control machine 2. The central control machine 2 adjusts the operation according to the feedback, and the voice prompt and alarm circuit provides voice prompts and alarms during the operation. The whole process realizes one-stop first aid operations for critically ill patients.

[0055] In summary, the present invention integrates functions such as heart rhythm detection and judgment, defibrillation control, and cardiopulmonary resuscitation control. The central control machine 2 coordinates the work of each functional module, and by setting an electrode plate storage box that can automatically apply conductive paste, it can achieve efficient, convenient, and integrated first aid operations for critically ill patients.

However, those skilled in the art can fully understand the present invention without these detailed descriptions. In addition, well-known methods, processes, procedures, components, and circuits are not described in detail to avoid unnecessary confusion to the essence of the present invention.
