Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and particularly relates to a standard Valsalva maneuver assistance system and a working method thereof. Background Art

[0002] The statements in this part only provide background technical information related to the present invention and do not necessarily constitute prior art.

[0003] The Valsalva maneuver is a means for diagnosing patent foramen ovale and supraventricular tachycardia, and the Valsalva maneuver plays an important role in the diagnosis of patent foramen ovale and supraventricular tachycardia. This maneuver triggers a series of physiological changes in the body through a specific breathing regulation method, thereby providing key clues for disease diagnosis. However, in the actual application process, the Valsalva maneuver has many limitations, such as difficulties in implementing operation specifications. When performing the Valsalva maneuver, the patient is required to close the glottis in a normal or deep inhalation state, then exhale forcefully and maintain a certain pressure for 5 - 10 seconds, and finally release the exhalation. However, during this process, due to individual differences among patients, including differences in respiratory muscle strength, respiratory control ability, and the degree of understanding and execution of instructions, it is difficult to unify the degree of forceful exhalation for each person; it is difficult to be widely applied in clinical practice. The commonly used alternative method is to let the patient blow forcefully into a 10 - ml syringe. However, this method can only roughly reflect the patient's force, and cannot accurately quantify the expiratory pressure. When different patients blow into the syringe, due to different force application methods and degrees, the resulting pressure fluctuation range is large, making it difficult to observe the expiratory pressure of the Valsalva maneuver, difficult to maintain it at a stable level, and even more impossible to achieve standardization. Summary of the Invention

[0004] In view of the above problems, the present invention provides a standard Valsalva maneuver assistance system and a working method thereof, which solve the problems of unstable expiratory pressure of the Valsalva maneuver, inability to accurately quantify the expiratory pressure, and inability to standardize the expiratory time.

When the pressure reaches the set pressure value, the control device can control the execution device and the timing device based on this signal, which helps to guide the patient to maintain a relatively stable exhalation pressure.

[0027] Example 1

[0028] This embodiment provides a standard Valsalva maneuver assistance system, as Figures 1 - 3 shown, including: a monitoring device, a control device, and an execution device; the monitoring device includes a pressure monitoring device 1 and a timing device 3; both the pressure monitoring device 1 and the timing device 3 are connected to the control device, and the control device is further connected to the execution device; the control device is configured to control the working states of the timing device 3 and the execution device according to the pressure signal of the pressure monitoring device 1; the execution device is configured to inject an acoustic contrast agent into the patient;

[0029] The monitoring device further includes a housing 2, a gas pipeline, and a face mask 6; both the pressure monitoring device 1 and the timer are arranged inside the housing 2, both the pressure monitoring device 1 and the timing device 3 are arranged on the bottom plate of the housing 2 through a fixing bracket 8, and the pressure monitoring device 1 is connected to the face mask 6 through the gas pipeline.

[0030] Further, the gas pipeline includes a first air pipe 9, a second air pipe 4, and an air pipe adapter 7; one end of the first air pipe 9 is connected to the pressure monitoring device 1, and the other end is connected to the air pipe adapter 7; one end of the second air pipe 4 is connected to the air pipe adapter 7, and the other end is connected to the face mask 6; the air pipe adapter 7 is fixedly arranged on the housing 2 of the detection device.

[0031] The pressure monitoring device 1 includes a barometer and a pressure sensor, the barometer is configured to display the real-time pressure during the patient's exhalation; the pressure sensor is connected to the control device and is configured to provide a real-time pressure signal for the control device. The traditional clinical method of asking the patient to blow forcefully into a 10-ml syringe can only roughly reflect the patient's exertion and cannot accurately quantify the exhalation pressure. The present invention utilizes the barometer and the pressure sensor in the pressure monitoring device 1 to achieve accurate measurement and quantification of the exhalation pressure, providing more accurate data for diagnosis.

[0032] Further, the timing device 3 is an electronic stopwatch. After the pressure monitoring device 1 reaches the set pressure, the control device will control the start of the electronic stopwatch for timing to guide the patient to maintain an effective breath-holding time, avoiding the problem of inconsistent breath-holding durations in traditional methods, which leads to the need for multiple breath-holding attempts.

[0033] The control device is a PLC control system with execution logic and timing functions. The control system receives and sends control instructions based on the timing function inside the PLC control system, and the electronic stopwatch only serves as a reference and guiding role.

[0034] The execution device is an intravenous infusion pump, which is a commonly used device in clinical practice and can perform operations such as setting the duration according to actual needs by itself.

[0035] The mask 6 includes a mask 6 body and a diameter converter 5; the mask 6 body is a medical mask 6, a sealing pad is provided on the mask 6 body, and the diameter converter 5 is used to connect the mask 6 body and the second trachea 4.

[0036] Embodiment 2

[0037] This embodiment provides a working method of a standard Valsalva maneuver assistance system, including:

[0038] The pressure monitoring device 1 receives the gas exhaled by the object to be executed through a gas pipeline. The reading of the pressure monitoring device 1 continuously rises. When the pressure reaches the set pressure value, the control device receives the pressure signal from the pressure monitoring device, and the control device sends a start instruction to the timing device 3 and the execution device. During this process, the pressure needs to be maintained. The execution device starts and lasts for a set duration; after reaching the set duration, the pressure is relieved, the pressure of the pressure monitoring device 1 drops, and the control device stops the control program and the execution device stops. This solves the problem that it is difficult to unify the respiratory muscle strength and respiratory control ability, and the pressure monitoring device 1 is used to guide and maintain a stable expiratory pressure.

[0039] The flow rate of the infusion pump is set through its own control panel; the timing device 3 is started by the control device according to the pressure monitoring signal, and at the same time, the working duration of the execution device and the pressure maintenance duration are associated. The pressure maintenance duration (expiratory pressure maintenance time) is standardized to 5 - 10 s, which solves the problem that the expiratory time cannot be standardized and improves the accuracy and stability of the working process.

[0040] Although the specific implementation manners of the present invention are described above in conjunction with the drawings, it is not a limitation to the protection scope of the present invention. Those skilled in the art should understand that based on the technical solutions of the present invention, various modifications or deformations that can be made by those skilled in the art without creative labor are still within the protection scope of the present invention.
