Description

Technical Field

[0001] This utility model relates to the field of cardiac resuscitation equipment technology, and in particular to a ventilation device. Background Technology

[0002] In current emergency procedures, a 30:2 compression ratio requires at least two medical personnel. One person performs compressions and counts to 30, while the other provides two breaths. In public settings, there are also cases where only one person performs compressions and breaths (mouth-to-mouth resuscitation). Using only one person increases the workload and leads to a decrease in the quality of CPR over time. With two personnel, very close coordination is needed to improve the quality of CPR. For example, if the person performing compressions counts to 30, the person performing ventilation should provide two even breaths, and then the person performing compressions should continue. This lack of coordination can result in excessively long periods without compressions, which is detrimental to CPR. Furthermore, the subjective nature of the ventilation operator's experience in controlling pressure can easily force air into the patient's stomach, further reducing the quality of resuscitation.

[0003] To address this, emergency ventilators have emerged on the market. Typically, CPR personnel set these ventilators to manual ventilation mode. When the chest compression operator counts to 30 compressions, the ventilation operator uses the ventilator to provide mechanical ventilation. While this solves the problem of air entering the stomach, it doesn't address the issue of seamless coordination between compressions and ventilation, nor does it allow for assessment of the quality of compressions over time. Another common approach is to integrate a metronome into an AED (Automated External Defibrillator), allowing the operator to perform compressions and ventilations in rhythm with the metronome. While this addresses the issue of uneven compression frequency to some extent, it still doesn't solve the problems of compression depth and ventilation quality.

[0004] Therefore, there is an urgent need to provide a new type of ventilation device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a ventilation device that solves the problem of ventilation quality that existing cardiac resuscitation equipment cannot address.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A ventilation device, comprising:

[0008] The main component includes an air inlet connected to an air source, an air outlet connected to the air inlet, and a voice module capable of providing a specified pressing frequency.

[0009] A breathing device is connected to the main body. The breathing device has a breathing port that is connected to an air outlet. The main body is also equipped with a pressure sensor for detecting the pressure of the breathing port.

[0010] The control component is electrically connected to the pressure sensor and the voice module respectively. When the pressure sensor detects that the pressure at the breathing port is greater than the preset pressure, the control component controls the voice module to sound an alarm.

[0011] Preferably, the main component also includes a main control valve, through which the air inlet and outlet are connected.

[0012] Preferably, the main component also includes a power supply, which is connected to the main control valve and the control assembly, respectively.

[0013] Preferably, the main body also includes an LED light for displaying the remaining power of the power supply, which is connected to both the power supply and the control components.

[0014] Preferably, the main body also includes buttons located on its outer side, which are connected to the power supply and control components respectively.

[0015] Preferably, the main body also includes a drainage cap and a one-way valve, with the air outlet connected to the breathing port in sequence through the drainage cap and the one-way valve.

[0016] Preferably, the breathing device includes:

[0017] The first channel is located around the outside of the breathing port and is used to house a one-way valve.

[0018] The second channel is arranged around the outside of the first channel and is connected to the pressure sensor;

[0019] The breathing port is provided with a third channel that runs through the second channel. The pressure sensor is connected to the breathing port through the second channel and the third channel in sequence to detect the pressure of the breathing port.

[0020] Preferably, the breathing device also includes an exhaust port, which is connected to the first channel. When the patient exhales, the gas enters the breathing port, pushes open the base of the one-way valve and connects with the first channel, and then discharges the gas through the exhaust port.

[0021] Preferably, it also includes a top cover, which is threaded to the main body and located above the main body.

[0022] The beneficial effects of this utility model are:

[0023] This invention utilizes a voice module that can provide a specified compression frequency, enabling medical staff to operate according to the voice prompts of the voice module. Moreover, the ventilation device can automatically control ventilation after detecting a certain number of compressions. At the same time, a pressure sensor detects the pressure at the patient's end, and the voice module can sound an alarm when the pressure exceeds the preset value. This solves the problem of ventilation quality that existing cardiac resuscitation equipment cannot address. Attached Figure Description

[0032] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0033] like Figure 1 The image shown is a front view of a ventilation device provided by this utility model. The ventilation device, from top to bottom, includes an upper cover 1, a main body 2, and a breathing element 3. The main body 2 is connected to the upper cover 1 and the breathing element 3, respectively.

[0034] The outer side of the main body 2 is provided with an air inlet 21 that is connected to an air source (not shown in the figure) and a button 23 for controlling the opening and closing of the ventilation device. The bottom of the breathing device 3 is provided with a breathing port 31 that is connected to the patient end for ventilation.

[0035] like Figure 2As shown, this is a top view of the main body 2. The main body 2 has a support plate 27 inside. The upper space of the support plate 27 is provided with a voice module and LED light placement position 24, a main control valve placement position 25, and a power supply placement position 26. That is, the voice module and LED light placement position 24 is used to place the voice module and LED light (not shown in the figure), the main control valve placement position 25 is used to place the main control valve (not shown in the figure), and the power supply placement position 26 is used to place the power supply (not shown in the figure). Specifically, healthcare workers attach a patch (a type of sensor) to the patient's chest. This patch automatically calculates the compression frequency and depth. When the compression frequency is outside the range of 100-120 compressions per minute, the ventilation device controls the voice module to issue a voice prompt, reminding the healthcare worker to maintain the indicated frequency. When the compression frequency is between 100-120 compressions per minute, the voice module stops working. When the compression depth is outside the range of 5-6 centimeters, the voice module and LED lights work together to remind the healthcare worker to pay attention to the compression depth. In the 30:2 ventilation mode, the patch automatically provides two vents when it senses 30 compressions, and the healthcare worker immediately resumes compressions after the venting period ends. In the chest compression and ventilation synchronized mode, when the device senses that a medical staff member is pulling on the patient's chest, it introduces approximately 10 to 500 ml of oxygen, air, or a mixture of both. When the patch senses that the medical staff member is pressing again, it stops the ventilation.

[0036] Specifically, the voice module provides a specified compression frequency in CPR (cardiac resuscitation) mode, and the LED lights are used to display the remaining power. The LED lights are lit in four segments, with each segment representing 25% of the power. Each time the device is powered on, the voice module will announce the remaining power and an estimated time that the power can still be used (e.g., approximately 50% remaining power, estimated to last for 5 hours). When the power is too low or a component malfunctions, the LED lights will flash red, and the voice module will announce the fault.

[0037] Specifically, the ventilation device also includes a control component. The main body 2 is equipped with a pressure sensor for detecting the pressure at the breathing port 31. The control component is electrically connected to both the pressure sensor and the voice module. When the pressure sensor detects that the pressure at the breathing port 31 is greater than a preset pressure (e.g., 45 H2O cm), the control component activates the voice module to sound an alarm. Alternatively, when the power supply is too low (e.g., below 20%), the control component will also activate the voice module to sound an alarm, and the LED will flash red. Its working principle is: using the pressure sensor to detect pressure at the patient end, thus ensuring the reliability of the patient's breathing in the spontaneous breathing mode of the ventilation device. The overpressure alarm and low power alarm functions also provide convenience for patient safety and medical staff monitoring.

[0038] like Figure 3As shown, this is a bottom schematic diagram of the main body 2. The support plate 27 has an air outlet 22 and a threaded hole for fixing the main control valve. A pressure sensor detection port 28 is also provided at the bottom of the main body 2. Specifically, the main body 2 also includes a drainage cap and a one-way valve (neither shown in the figure). The air outlet 22 is connected to the breathing port 31 in sequence through the drainage cap and the one-way valve. Figure 4 This is a schematic diagram of the structure of the breathing device 3. The breathing device 3 includes a breathing port 31, a first channel 32, a second channel 33, and a third channel 34. The breathing port 31 is connected to the patient end. The first channel 32 is arranged around the outside of the breathing port 31 and is used to house a one-way valve. The second channel 33 is arranged around the outside of the first channel 32 and is connected to a pressure sensor (i.e., connected to the pressure sensor detection port 28). The breathing port 31 has a third channel 34 that penetrates the second channel 33. The pressure sensor is connected to the breathing port 31 through the second channel 33 and the third channel 34 in sequence to detect the pressure of the breathing port 31.

[0039] Specifically, the breathing device 3 also includes an exhaust port (not shown in the figure), which is connected to the first channel 32. When the patient exhales, the gas enters the breathing port 31, pushes open the base of the one-way valve and connects with the first channel 32, and then discharges the gas through the exhaust port.

For those skilled in the art, other variations or modifications can be made based on the above description.
