Description
A portable lung condition calibration device and calibration method Technical Field
[0001] This invention relates to the field of medical device technology, and in particular to a portable lung condition calibration device and calibration method. Background Technology
[0002] Lung surgery refers to a series of surgical procedures performed on the human lungs. Broadly speaking, it can be divided into two categories based on the surgical method: minimally invasive lung surgery and open-chest surgery. It is mainly used to treat diseases such as pulmonary bullae, lung infections, lung tumors, and tracheal tumors. Currently, for minimally invasive lung surgeries requiring precise positioning, such as minimally invasive lung nodule surgery and lung ablation, CT scan guidance is generally used. However, because the lungs are the human respiratory organs, their size constantly changes during the procedure due to the patient's breathing, making it difficult to accurately locate the surgical site using only a CT scan. Summary of the Invention

[0013] Furthermore, the air blowing part is detachably connected to the main body of the device.
[0014] Furthermore, the indicator unit includes a first indicator light, a second indicator light, and a third indicator light. The second indicator light corresponds to the optimal flow rate setting, the first indicator light corresponds to a flow rate setting below the optimal flow rate setting, and the third indicator light corresponds to a flow rate setting above the optimal flow rate setting.
[0015] Furthermore, the indicator also includes an audio prompter that corresponds to the optimal flow rate setting and is electrically connected to the control system.
[0016] Furthermore, the blowing part is a disposable blowing nozzle.
[0017] Furthermore, the flow detection unit is a flow sensor.
[0018] Furthermore, the calibration device also includes an adjustment unit for adjusting the flow range, which is electrically connected to the control system.
[0019] Furthermore, the adjustment unit is electrically connected to the indicator unit.
[0020] The technical solution provided according to the second objective of the present invention is as follows:
[0021] A method for lung condition calibration includes the following steps:
[0022] S1. Prepare the imaging equipment and the aforementioned portable lung condition calibration device, and electrically connect the imaging equipment to the portable lung condition calibration device.
[0023] S2. The patient blows air into the air delivery unit, the blowing speed is detected by the flow detection unit, and the patient's lung condition is observed by imaging equipment.
[0024] S3. When the imaging equipment observes that the patient's lungs have reached the optimal surgical condition, the calibration unit calibrates the blowing speed and the indicator unit indicates the condition to accurately calibrate the patient's optimal lung blowing condition.
[0025] Beneficial effects:
[0026] 1) The portable lung condition calibration device of the present invention has a simple structure and can conveniently, quickly and accurately calibrate the lung condition of patients, thereby meeting the requirements of lung surgery.
[0027] 2) The lung condition calibration method of the present invention is electrically connected to the imaging equipment. When the patient blows air into the calibration device, the medical staff can directly observe the patient's lung condition through the imaging equipment. Thus, when the patient's lungs reach the optimal state, the calibration device can directly calibrate the blowing speed, which has the characteristics of high efficiency and accuracy.
[0028] The principle of lung condition calibration in this invention is as follows: Before surgery, the calibration device is electrically connected to the imaging equipment. The patient blows air into the air delivery unit, and the airflow detection unit detects the blowing speed and feeds it back to the control system. Simultaneously, medical staff observe the patient's lung condition, i.e., lung size, in real time through the imaging equipment. When the patient's lungs are observed to reach the optimal size for surgery, the medical staff calibrates the lungs using the calibration unit and indicates this optimal state through the indicator unit. Since the control system is electrically connected to the imaging equipment, and the flow detection unit, calibration unit, and indicator unit are all electrically connected to the control system, when the medical staff observes that the patient's lungs have reached the optimal size for surgery through the imaging equipment, the calibration unit calibrates the blowing speed for this optimal lung size and indicates the blowing speed to be reached through the indicator unit, thereby accurately calibrating the patient's optimal lung blowing state. When the patient undergoes surgery, the patient blows air into the calibration device. When the blowing speed reaches the calibrated blowing speed, the indicator unit provides an indication to inform the medical staff that surgery is appropriate at this time. Then, under the guidance of the imaging equipment, the medical staff can accurately perform lung surgery. Attached Figure Description

The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
[0035] Referring to Figure 1, this embodiment provides a portable lung condition calibration device, which is electrically connected to imaging equipment. It includes an air blowing unit 1, a control system, a flow detection unit, a calibration unit 2, and an indicator unit 3. The control system is electrically connected to the imaging equipment, the flow detection unit is connected to the air blowing unit 1, and the flow detection unit, calibration unit 2, and indicator unit 3 are all electrically connected to the control system. The calibration device has a simple structure and can conveniently, quickly, and accurately calibrate the patient's lung condition, thereby meeting the requirements of lung surgery.
[0036] This embodiment also provides a method for lung status calibration, including the following steps:
[0037] S1. Prepare the imaging equipment and the aforementioned portable lung condition calibration device, and electrically connect the imaging equipment to the portable lung condition calibration device.
[0038] S2. The patient blows air into the air inflator 1, the air blowing speed is detected by the flow detection unit, and the patient's lung condition is observed by the imaging equipment.
[0039] S3. When the imaging equipment observes that the patient's lungs have reached the optimal surgical state, the calibration unit 2 calibrates the blowing speed and the indicator unit 3 indicates the state to accurately calibrate the patient's optimal lung blowing state.
[0040] The lung condition calibration method in this embodiment is electrically connected to imaging equipment. When the patient blows air into the calibration device, medical staff can directly observe the patient's lung condition through the imaging equipment. Thus, when the patient's lungs reach the optimal state, the calibration device can directly calibrate the blowing speed, which is highly efficient and accurate.
[0041] The lung condition calibration principle of this embodiment is as follows: Before surgery, the calibration device is electrically connected to the imaging equipment. The patient blows air into the blowing unit 1, and the blowing speed is detected by the flow detection unit and fed back to the control system. At the same time, medical staff observe the patient's lung condition, i.e., lung size, in real time through the imaging equipment. When the patient's lungs are observed to reach the optimal size for surgery, the medical staff calibrates the lungs using the calibration unit 2 and indicates this optimal state through the indicator unit 3. Since the control system is electrically connected to the imaging equipment, and the flow detection unit, calibration unit 2, and indicator unit 3 are all electrically connected to the control system, when the medical staff observes that the patient's lungs have reached the optimal size for surgery through the imaging equipment, the calibration unit 2 calibrates the blowing speed for this optimal lung size and indicates the blowing speed to be reached through the indicator unit 3, thereby accurately calibrating the patient's optimal lung blowing state. When the patient undergoes surgery, the patient blows air into the calibration device. When the blowing speed reaches the calibrated blowing speed, the indicator unit 3 provides an indication to inform the medical staff that surgery is appropriate at this time. Then, under the guidance of the imaging equipment, the medical staff can accurately perform lung surgery.
[0042] Specifically, the portable lung condition calibration device of this embodiment includes a device body 4, with an air blowing unit 1, a control system, a flow detection unit, a calibration unit 2, and an indicator unit 3 all disposed within the device body 4. More specifically, the control system and the flow detection unit are located inside the device body 4 and are electrically connected. The air blowing unit 1 is mounted on the device body 4 and connected to the flow detection unit inside the device body 4. The calibration unit 2 and the indicator unit 3 are both disposed on the device body 4 and are electrically connected to the control system. The calibration device is electrically connected to the imaging equipment through the control system. Because the air blowing unit 1, the control system, the flow detection unit, the calibration unit 2, and the indicator unit 3 are all disposed within the device body 4, the calibration device of this embodiment is compact and easy to carry.
[0043] The control system can be a PLC processor or other device with data recording and control functions, which are common in existing technologies. The flow detection unit can be a flow sensor, which is common in existing technologies, to detect the patient's blowing speed. The imaging equipment can be a CT scanner to observe the patient's lung condition and the location where surgery needs to be performed. The calibration unit 2 can be a calibration button electrically connected to the control system. When the imaging equipment observes that the patient's lungs have reached the optimal surgical condition, medical staff can press the calibration unit 2 to perform calibration.
[0044] Furthermore, since the calibration device requires the patient to blow air into the air inlet 1, to ensure the safety and hygiene of the calibration device and to ensure its repeated long-term use, the air inlet 1 is detachably connected to the device body 4, so that the air inlet 1 can be removed and replaced after the patient's use. At the same time, to reduce material costs, the air inlet 1 in this embodiment is a disposable air nozzle.
[0045] The indicator unit 3 in this embodiment includes a first indicator light 31, a second indicator light 32, and a third indicator light 33. All three indicators are electrically connected to the control system and correspond to different blowing speed values or ranges, i.e., different flow rate values or ranges. Specifically, the second indicator light 32 corresponds to the optimal flow rate setting, the first indicator light 31 corresponds to a flow rate below the optimal setting, and the third indicator light 33 corresponds to a flow rate above the optimal setting. The optimal flow rate is the blowing speed at which the imaging equipment observes that the patient's lungs have reached the optimal size suitable for surgery. Therefore, when the patient's blowing speed is below the optimal blowing speed, the first indicator light 31 illuminates or flashes; when the patient's blowing speed reaches the optimal blowing speed, the second indicator light 32 illuminates or flashes; and when the patient's blowing speed is above the optimal blowing speed, the third indicator light 33 illuminates or flashes. Thus, the three indicator lights can accurately determine when surgery is appropriate.
[0046] It should be noted that, strictly speaking, each patient has a specific optimal lung size for surgery, which corresponds to a specific ventilation rate. However, in practice, achieving precise alignment with this specific value is quite difficult and may prevent the surgery from proceeding. Therefore, each patient has a range of optimal lung sizes suitable for surgery, which corresponds to a specific range of ventilation rates that are relatively easy to achieve, allowing for a quick and smooth surgical procedure.
[0047] Furthermore, the indicator unit 3 also includes an audio prompter, which corresponds to the optimal flow rate setting and is electrically connected to the control system. When the patient's blowing speed reaches the optimal blowing speed, the audio prompter sounds to better alert medical staff and prevent the second indicator light 32 from being lit or flashing unnoticed and affecting the surgery.
[0048] Therefore, the calibration principle of this embodiment is as follows: Before the patient's surgery, the calibration device is electrically connected to the imaging equipment. The patient blows air into the air blowing unit 1, and the air blowing speed is detected by the flow detection unit and fed back to the control system. At the same time, medical staff observe the patient's lung condition, i.e., lung size, in real time through the imaging equipment. When the patient's lungs are observed to have reached the optimal size for surgery, the medical staff performs calibration by pressing the calibration unit 2, and the second indicator light 32 illuminates or flashes, and the sound prompter emits an audible signal to provide an indication. Since the control system is electrically connected to the imaging equipment, and the flow detection unit, calibration unit 2, and indicator unit 3 are all electrically connected to the control system, when the medical staff observes through the imaging equipment that the patient's lungs have reached the optimal size for surgery, the calibration unit 2 will calibrate the air blowing speed for that optimal lung size, and indicate the reaching of that air blowing speed through the illumination or flashing of the second indicator light 32 and the sound prompter, thereby accurately calibrating the patient's optimal lung blowing state. When a patient is undergoing surgery, the patient blows air into the calibration device. When the blowing speed reaches the calibrated blowing speed, the second indicator light 32 and the sound prompt will indicate to the medical staff that it is appropriate to perform surgery at this time. Then, under the guidance of the imaging equipment, the medical staff can accurately perform surgery on the lungs.
[0049] It should be noted that the optimal blowing speed and range for different patients' lung conditions vary, and in such cases, recalibration is sufficient.
[0050] In addition, the calibration device of this embodiment also includes an adjustment unit 5 for adjusting the flow range. The adjustment unit 5 is electrically connected to the control system and to the indicator unit 3. Thus, the acceptable range of the air volume of the calibration device can be adjusted by the adjustment unit 5, and the degree of change of the acceptable range can be indicated by the indicator unit 3. For example, when the acceptable range of the air volume becomes narrower, the first indicator light 31 is lit or flashes; when the acceptable range of the air volume is moderate, the second indicator light 32 is lit or flashes; and when the acceptable range of the air volume becomes wider, the third indicator light 33 is lit or flashes.
[0051] Surgery can be performed once the air volume reaches the optimal range for the procedure. However, the optimal lung size varies from patient to patient, so each patient needs to be calibrated before surgery. Furthermore, the optimal lung size range also differs for each patient, so the adjustment unit 5 needs to be adjusted to the range corresponding to the patient. The changes in the range can be clearly seen through indicator lights, allowing medical staff to understand the patient's condition.
[0052] The technical means disclosed in this invention are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this invention, and these improvements and modifications are also considered within the scope of protection of this invention.
