Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, in particular to an anti-suffocation device with a head posture detection alarm. Background Art

[0002] Asphyxiation on vomitus is a common and dangerous condition. Fighting, running fast, being intoxicated, or drowning can all cause stomach contents to regurgitate unexpectedly and be aspirated into the airway, leading to asphyxiation. Without effective monitoring, asphyxiation can't be relieved promptly, potentially leading to death.

[0003] Chinese patent CN107432802A discloses a multifunctional vomit collection and anti-suffocation device that adjusts the position of the patient's head. The rectangular inflatable device is designed to tilt the patient's head, effectively preventing the patient's head from tilting upward, which could cause vomitus to block the trachea and ultimately lead to suffocation and other unexpected dangers. Clinical experience has shown that rectangular inflatable devices cannot completely fit the patient's head and often separate from the patient's head due to unconscious movement, causing the head to return to a suffocating position and causing danger. In other words, traditional rectangular inflatable anti-suffocation devices rely on the professional qualifications of nursing staff and cannot effectively reduce the time spent accompanying patients. Summary of the Invention

[0004] The purpose of the present invention is to provide an anti-suffocation device with head posture detection alarm in order to overcome the defects of the above-mentioned prior art.

[0005] The purpose of the present invention can be achieved by the following technical solutions:

[0006] An anti-suffocation device with a head posture detection alarm, the device comprising a neck airbag and a head airbag. The neck airbag, when inflated, presents an arcuate surface that fits the human neck. The head airbag is located above the middle of the neck airbag, and when inflated, the neck airbag elevates the human head.

[0007] The neck airbag and the head airbag are respectively provided with a spacer to separate the two into two airbag cavities. The neck airbag forms a symmetrical left neck airbag cavity and a right neck airbag cavity, and the head airbag forms a symmetrical left head airbag cavity and a right head airbag cavity. The four airbag cavities are all connected to the inflation and exhaust components.

[0008] The neck airbag and the head airbag are provided with a head posture detection sensor component, and the head posture detection sensor component is connected to the alarm component.

[0009] The inflation and exhaust assembly includes a rotary inflation and exhaust valve, which is provided with four gas channels and a rotary dial block. The four gas channels are respectively connected to the four airbag chambers. The rotary dial block is provided with a first gas port and a second gas port that are interconnected. The first gas port is used to connect to an external pressurized ball. When any airbag chamber needs to be inflated, the rotary dial block is rotated to align the second gas port with the gas channel connected to the airbag chamber to be inflated. When wearing the device, first use the pressurized balloon to connect the inflation and exhaust assembly to inflate the airbag chamber. Select the airbag chamber to be inflated by dialing the rotary dial block. All four airbag chambers need to be inflated to an appropriate amount, but the amount of air inflated in one airbag chamber should be greater than that on the other side to ensure that the head posture is tilted.

[0010] The head posture detection sensor component includes a pressure sensor arranged in the head airbag area and a neck level meter arranged in the neck airbag area. The pressure sensor and the neck level meter are both connected to the alarm component.

[0011] Two pressure sensors are provided, which are symmetrically distributed in the left head airbag cavity and the right head airbag cavity respectively, and both pressure sensors are connected to the alarm component.

[0012] The neck level is arranged at the symmetrical center position of the middle part of the neck airbag.

[0013] The alarm component includes a processor, an alarm and a power supply. The pressure sensor and the neck level are both connected to the processor input end, the processor output end is connected to the alarm, and the power supply is respectively connected to the processor and the alarm.

[0014] The power supply includes a button battery.

[0015] The alarm device includes an audible and visual alarm device.

[0017] (1) The present invention provides a symmetrical airbag cavity, which can achieve head tilt by varying the amount of air inflated, thus preventing suffocation. Furthermore, the neck airbag and the head airbag are designed to be separate. The neck airbag forms a surrounding structure around the neck after inflation, making it difficult to slip during use. The head airbag can elevate the head, further unblocking the airway and ensuring safety.

[0018] (2) The present invention provides a head posture detection sensor component to realize unattended automatic posture detection alarm, which can significantly shorten the time required for patients to accompany them and free up the manpower required for accompanying patients;

[0019] (3) The head posture detection of the present invention performs dual detection. First, the two pressure sensors in the head airbag area detect the head pressure. Second, the neck level meter in the neck airbag area detects the tilt angle. When the head of the monitored person moves, an abnormal alarm can be issued to remind the nursing staff to adjust the patient's posture in time to ensure safety.

[0020] (4) The present invention is inexpensive, has low single-use medical expenses, and can be used repeatedly, thereby relatively reducing the medical expenses paid by patients;

[0021] (5) The present invention is easy to promote: the process of wearing the device is convenient and easy, and the patient's family can help the patient wear it correctly after simple training.

DETAILED DESCRIPTION

[0028] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. Note that the following embodiments are merely illustrative in nature and the present invention is not intended to limit its applicable objects or uses, and the present invention is not limited to the following embodiments.

[0029] Example

[0030] like Figures 1 to 3 As shown, an anti-suffocation device with head posture detection and alarm includes a neck airbag and a head airbag. When the neck airbag is inflated, it presents an arc surface that fits the human neck. The head airbag is located above the middle of the neck airbag. When the neck airbag is inflated, it raises the human head.

[0031] The neck airbag and the head airbag are respectively provided with a spacer to separate the two into two airbag cavities. The neck airbag forms a symmetrical left neck airbag cavity 1 and a right neck airbag cavity 2, and the head airbag forms a symmetrical left head airbag cavity 3 and a right head airbag cavity 4. All four airbag cavities are connected to the inflation and exhaust components.

[0032] A head posture detection sensor component is provided in the neck airbag and the head airbag, and the head posture detection sensor component is connected to the alarm component 8.

[0033] like Figure 4 As shown, the inflation and exhaust assembly includes a rotary inflation and exhaust valve 5, which is provided with four gas channels 51 and a rotary dial block 52. The four gas channels 51 are respectively connected to the four airbag cavities, and the rotary dial block 52 is provided with a first gas port 53 and a second gas port 54 that are interconnected. The first gas port 53 is used to connect to an external pressurizing ball 9. When it is necessary to inflate any airbag cavity, the rotary dial block 52 is turned to align the second gas port 54 with the gas channel 51 connected to the airbag cavity to be inflated. The pressurizing ball 9 used in this embodiment is as shown in FIG. Figure 5 shown.

[0034] The head posture detection sensor assembly includes a pressure sensor 6 located in the head airbag area and a neck level gauge 7 located in the neck airbag area. Both pressure sensor 6 and neck level gauge 7 are connected to an alarm assembly 8. Two pressure sensors 6 are provided, symmetrically located in the left and right head airbag cavities 3 and 4, respectively. Both pressure sensors 6 are connected to the alarm assembly 8. The neck level gauge 7 is located symmetrically in the middle of the neck airbag.

[0035] The alarm assembly 8 includes a processor, an alarm, and a power supply. The pressure sensor 6 and the neck level 7 are both connected to the processor input, the processor output is connected to the alarm, and the power supply is connected to the processor and the alarm, respectively. The power supply uses a button battery, and the alarm uses an audible and visual alarm, including a buzzer and an LED indicator. The buzzer and LED indicator are both connected to the processor. In this embodiment, the processor is a single-chip microcomputer chip.

[0036] The working principle of the anti-suffocation device with head posture detection alarm of the present invention is:

[0037] (1) Wearing process

[0038] When wearing the device, first use the pressurized balloon connected to the inflation and exhaust assembly to inflate the airbag chamber. The airbag chamber to be inflated is selected by turning the rotary dial 52. All four airbag chambers should be inflated to the appropriate amount, but the amount of air in one airbag chamber should be greater than that in the other to ensure that the head is tilted. After use, the caregiver can deflate the device through the exhaust assembly and remove it.

[0039] (2) Starting and stopping the posture detection alarm

[0040] When the inflation is complete and the device is worn correctly, the nurse places the patient on the monitoring bed in the correct posture with the head tilted to one side and slightly raised, and manually turns on the central switch of the device.

[0041] After the system is turned on, the built-in program initializes and the LED indicator flashes blue. Initialization records the patient's head pressure on the airbag (in the correct position placed by the caregiver) and the angle between the neck level and the earth's gravity. The system also checks the battery level and whether the buzzer is functioning properly.

[0042] When all tests are complete, the LED indicator lights solid blue, indicating the system is operating normally. When the head-to-head airbag pressure decreases or the angle between the neck level gauge 7 and the Earth's gravity decreases beyond a set threshold, the pressure sensor 6 and the neck level gauge 7 detect the corresponding changes and transmit this information to the processor. The processor determines that the patient's head posture is abnormal, a buzzer sounds, and the LED indicator flashes red, alerting the caregiver to adjust the patient's posture promptly. Once the posture returns to normal, the detection system stops alarming.

[0043] The present invention features symmetrically structured airbag chambers that tilt the head by varying the amount of air inflated, preventing suffocation. Separately, the neck and head airbags are designed. When inflated, the neck airbag forms a surrounding structure around the neck, preventing slippage during use. The head airbag elevates the head, further unblocking the airway and ensuring safety. A head posture detection sensor assembly enables unattended automatic posture detection and alarming, significantly reducing the time required for patient care and freeing up the required staff.

[0044] The above embodiments are merely examples and do not limit the scope of the present invention. These embodiments can be implemented in various other ways, and various omissions, replacements, and changes can be made without departing from the technical concept of the present invention.
