Description

Technical Field

[0001] This invention belongs to the field of medical equipment technology, and specifically relates to a medical air transport device. Background Technology

[0002] In the field of air medical transport, efficient and reliable medical equipment is crucial for ensuring patient safety. Traditional air transport scenarios require independent equipment such as transport ventilators, electrocardiogram monitors, and infusion pumps. While these devices can meet basic medical needs, they have revealed several technical shortcomings in practical applications. Specifically: the equipment is scattered, occupying a large space; medical staff need to frequently switch between different devices, leading to complex operations, low efficiency, and difficulty in real-time synchronous monitoring of the patient's overall condition; each device has its own power supply, resulting in unstable power and insufficient battery life in the aviation environment. Summary of the Invention

[0003] The purpose of this invention is to provide a medical air transport device to solve the problems of dispersed equipment, complex operation, and poor environmental adaptability in air transport mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a medical air transport device, comprising a protective shell and a protective cover, wherein a ventilator module, a micro-infusion pump module and an electrocardiogram monitoring module are installed inside the protective shell, and shock-absorbing pads are provided below the ventilator module and the micro-infusion pump module; the ventilator module is provided with a ventilation mode switching unit and a parameter adjustment unit; the micro-infusion pump module is provided with an infusion control unit and a safety protection unit; and the electrocardiogram monitoring module is provided with an electrocardiogram monitoring unit and a non-invasive blood pressure measurement unit.

[0005] In a further embodiment, the ventilation mode switching unit supports switching between CMV, ACV, SIMV and PSV modes, and the tidal volume adjustment range of the parameter adjustment unit is 20-1500mL, and the oxygen concentration adjustment range is 21%-100%.

[0006] In a further embodiment, the infusion control unit has 1-2 independent control functions, and the infusion rate is adjustable in the range of 0.1-1200mL / h. The safety protection unit consists of an anti-backflow valve and a bubble monitoring module.

[0007] In a further embodiment, the electrocardiogram monitoring unit supports 12 leads and has a built-in arrhythmia detection algorithm, and the measurement cycle of the non-invasive blood pressure measurement unit is adjustable from 5 to 30 minutes.

[0008] In a further embodiment, the protective housing is further provided with a power system, which includes a battery pack, a DC power socket, and an AC power socket.

[0009] In a further embodiment, two buckles are symmetrically fixed at the bottom of the protective cover, and two slots matching the buckles are formed on the surface of the protective shell.

[0010] In a further embodiment, unlocking buttons are provided on both outer walls of the protective housing, and multiple slide rail mounting interfaces are provided on the bottom of the protective housing.

[0011] The technical effects and advantages of this invention are as follows:

[0012] This medical air transport equipment integrates a ventilator module, a micro-infusion pump module, and an electrocardiogram monitoring module into a unified protective shell, replacing the traditional separate configuration of individual devices, reducing the space occupied by the equipment, avoiding medical staff from frequently switching between different devices, realizing "one machine with multiple functions", and greatly improving the efficiency of medical operations during air transport.

[0013] Shock-absorbing pads are installed under the ventilator module and the micro-pump module to effectively absorb the vibration energy during helicopter transportation, reduce the risk of damage to precision components due to turbulence, and ensure the accuracy of monitoring data and the reliability of the equipment. At the same time, the bottom slide rail mounting interface is precisely matched with the helicopter medical bracket, supporting quick push-in locking and press-to-unlock, which greatly shortens the equipment installation time and meets the urgent needs of air transport.

[0014] It covers four ventilation modes: CMV, ACV, SIMV, and PSV, to meet the respiratory support needs of patients with different conditions; the tidal volume (20-1500mL) and oxygen concentration (21%-100%) are adjustable over a wide range, and combined with the automatic weight-tidal volume algorithm (default 6-8mL / kg), it avoids the error of manual calculation and achieves precise ventilation therapy.

[0015] It supports simultaneous infusion of different drugs (such as vasoactive drugs + sedatives) through 1-2 channels to meet complex medication needs, and its efficiency is 50% higher than that of a single-channel pump; the infusion rate is adjustable from 0.1-1200mL / h, and it is compatible with 20 / 50mL syringes to adapt to various drug infusion scenarios.

[0016] Anti-reflux valve (unidirectional patency ≥99%) prevents blood backflow from contaminating the medication solution. Infrared bubble sensor (detection accuracy ≥0.5mL) and blockage pressure sensor (threshold 30-100kPa) monitor the infusion status in real time. In case of abnormality, the infusion is stopped immediately and the channel is locked to eliminate potential medication safety hazards.

[0017] The 12-lead ECG monitoring supports simultaneous acquisition of signals from limb and chest leads. The built-in arrhythmia detection algorithm automatically identifies 12 abnormal heart rhythms (such as atrial fibrillation and premature ventricular contractions). The waveform refresh rate is 250Hz, and the abnormal marking delay is <2 seconds, enabling rapid and accurate analysis of cardiac electrical activity. The non-invasive blood pressure measurement accuracy is ±3mmHg, and the SpO2 monitoring accuracy is ±2%. It supports automatic switching between adult and neonatal modes, covering patients of all ages.

[0018] Supports helicopter 12V DC power, 220V AC power, and built-in lithium battery (supports QC3.0 fast charging), adapting to diverse power environments during air transport; the battery pack supports hot-swappable replacement, ensuring uninterrupted operation of the equipment during battery swapping, avoiding monitoring and treatment interruptions due to power switching, and guaranteeing equipment endurance during long-term transport. This medical air transport equipment solves the problems of dispersed equipment, complex operation, and poor environmental adaptability during air transport, significantly improving medical efficiency and safety, and has outstanding novelty and creativity, making it suitable for air medical scenarios such as helicopters.

Detailed Implementation

[0030] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the invention. However, it will be apparent to those skilled in the art that the invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid obscuring the invention.

[0031] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this invention, and are explained here together.

[0032] This invention provides, for example Figure 1-9 The medical air transport device shown includes a protective shell 1 and a protective cover 2. Both the protective shell 1 and the protective cover 2 are made of carbon fiber composite material and are covered with an IP54-level waterproof and dustproof coating, which can resist water mist, dust and minor splashes in the cabin. The protective cover 2 covers the surface of the protective shell 1 and can provide comprehensive protection for the equipment inside the protective shell 1. Two buckles 3 are symmetrically fixed at the bottom of the protective cover 2. Two slots matching the buckles 3 are opened on the surface of the protective shell 1. Unlocking buttons 4 are provided on both sides of the outer wall of the protective shell 1. Grooves are opened on both sides of the outer wall of the protective cover 2. By pressing the unlocking button 4 and cooperating with the grooves on both sides of the protective cover 2, the protective cover 2 can be quickly removed from the protective shell 1, thereby facilitating the operation of the equipment inside the protective shell 1. Handles 12 are installed on both sides of the outer wall of the protective shell 1, which facilitates the movement of the equipment and improves the portability of the equipment. Multiple slide rail mounting interfaces 13 are provided at the bottom of the protective shell 1. The slide rail mounting interfaces 13 adopt standard slots and are precisely matched with the helicopter medical bracket, which can quickly complete the push-in locking or press-unlocking.

[0033] The protective housing 1 houses a ventilator module 6, a micro-infusion pump module 7, and an electrocardiogram monitoring module 8. Shock-absorbing pads 5 are located below the ventilator module 6 and the micro-infusion pump module 7. The ventilator module 6 contains a ventilation mode switching unit 601 and a parameter adjustment unit 602. The ventilation mode switching unit 601 supports four modes: CMV (controlled ventilation), ACV (assisted controlled ventilation), SIMV (synchronized intermittent mandatory ventilation), and PSV (pressure support ventilation). It monitors airway pressure (-50 to 100 cmH2O) and tidal volume in real time using a pressure sensor (accuracy ±1 cmH2O). The ventilation volume (20-1500mL, 10mL increment) and minute ventilation are controlled. The parameter adjustment unit 602 supports continuous adjustment of oxygen concentration from 21% to 100% (accuracy 1%) and PEEP 0-30cmH2O settings. It has a built-in weight-tidal volume algorithm (default 6-8mL / kg), which automatically generates recommended values ​​after the patient's weight is entered, avoiding errors from manual calculation. The gas source interface adopts a G5 / 8 standard oxygen input port (compatible with helicopter oxygen supply systems and high-pressure oxygen cylinders) and a 15mm Luer airway connection port (with a bacterial filter, filtration efficiency ≥99.9%) to ensure a clean ventilation circuit.

[0034] The micro-infusion pump module 7 is equipped with an infusion control unit 701 and a safety protection unit 702. The infusion control unit 701 supports 1-2 channels of independent control (compatible with 20 / 50mL syringes), and the stepper motor drive accuracy reaches ±0.1mL / h. It supports continuous infusion (0.1-1200mL / h), intermittent infusion (customizable infusion / pause time), and push mode (rapid infusion of loading dose, time ≤1 minute).

[0035] The safety protection unit 702 consists of an anti-reflux valve 7021 and a bubble monitoring module 7022. The anti-reflux valve 7021 (unidirectional patency ≥99%) prevents blood backflow from contaminating the medication. The bubble monitoring module 7022 is equipped with an infrared bubble sensor (detection accuracy ≥0.5mL) and a blockage pressure sensor (threshold 30-100kPa) to monitor the infusion status in real time. When bubbles or blockages are detected, the infusion is stopped immediately and the channel is locked. The dual-channel design supports the simultaneous infusion of different drugs (such as vasoactive drugs + sedatives), meeting complex medication needs and improving efficiency compared to a single-channel pump.

[0036] The ECG monitoring module 8 includes an ECG monitoring unit 801 and a non-invasive blood pressure measurement unit 802. The ECG monitoring module 8 integrates a 12-lead ECG monitoring unit 801 (gold-plated electrode interface, improving anti-interference capability by 30%), supporting simultaneous acquisition of limb leads (RA / LA / LL) and chest leads (V1-V6). It has a built-in arrhythmia detection chip that can automatically identify 12 abnormal heart rhythms, including atrial fibrillation and premature ventricular contractions, with a waveform refresh rate of 250Hz and an abnormal waveform marking delay of <2 seconds. The non-invasive blood pressure measurement unit 802 uses a cuff-type NIBP sensor (compatible with pediatric / adult cuffs), measuring systolic blood pressure / diastolic blood pressure / mean arterial pressure via oscillometric method. It supports automatic measurement cycles of 5-30 minutes and manual emergency triggering, with an accuracy of ±3mmHg. The finger clip-type pulse oximeter uses dual-wavelength spectral technology (red light 660nm / infrared light 940nm) to monitor SpO2 in real time (accuracy ±2%) and pulse rate, supporting automatic switching between adult and neonatal modes.

[0037] The protective housing 1 also houses a power system, which includes a battery pack 9, a DC power socket 10, and an AC power socket 11. It is compatible with helicopter 12V DC power and 220V AC power. The battery pack 9 uses lithium batteries and supports QC3.0 fast charging. The battery pack 9 supports hot-swapping and replacement, and the equipment does not stop running during the battery swapping process. At the same time, the protective housing 1 is also equipped with multiple USB ports for easy data export.

[0040] Working principle:

[0041] This medical air transport equipment can be quickly installed onto the medical support of a helicopter via the slide rail mounting interface 13 at the bottom of the protective shell 1. Ensure that the installation is secure, open the protective cover 2, connect the power supply (either the helicopter's 12V DC power supply or the equipment's own battery pack 9), start the equipment, and enter the standby state after each module completes its self-test.

[0042] Based on the patient's condition, the appropriate ventilation mode (such as CMV, ACV, etc.) is selected through the ventilation mode switching unit 601. The patient's weight is input into the parameter adjustment unit 602, and the device automatically generates a recommended tidal volume. Medical staff can fine-tune parameters such as tidal volume and oxygen concentration according to the actual situation. The gas source is connected through the G5 / 8 standard oxygen inlet. After being filtered by the bacterial filter, it is connected to the patient's airway through the 15mm Luer airway connector to achieve safe and accurate ventilation support.

[0043] The syringe containing the medication is installed into the corresponding channel of the infusion control unit 701. The infusion mode (continuous infusion, intermittent infusion, or push infusion mode) and infusion rate are set. The safety protection unit 702 monitors the infusion process in real time. The anti-reflux valve 7021 prevents blood backflow. The bubble detection module 7022 immediately stops the infusion and alarms when it detects bubbles or blockages to ensure medication safety. The dual-channel design supports the simultaneous infusion of two different drugs to meet complex medication needs.

[0044] The ECG electrode pads are attached to the corresponding parts of the patient's body and connected to the 12-lead interface of the ECG monitoring unit 801 to collect cardiac electrical signals in real time. The built-in arrhythmia detection algorithm automatically analyzes the ECG waveform, identifies and marks abnormal heart rhythms. The non-invasive blood pressure measurement unit 802 automatically measures the patient's blood pressure according to the set measurement cycle (5-30 minutes), and can also be manually triggered for emergency measurement. The finger clip pulse oximeter probe monitors SpO2 and pulse rate in real time, and the monitoring data is displayed on the device screen in real time, providing medical staff with comprehensive information on the patient's vital signs.
