Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to a visualized and quantified Valsalva respiratory function trainer. Background Art

[0002] The Valsalva maneuver is a commonly used maneuver in cardiovascular internal medicine examinations. The patient takes a deep breath, holds his breath, and then exhales forcefully. This maneuver can increase the pressure in the entire chest cavity, reduce the amount of blood returning to the heart, and activate the vagus nerve. This maneuver is required for differential examinations of some diseases. For example, patients with hypertrophic cardiomyopathy may have murmurs. The Valsalva maneuver can be used to identify the nature of the murmur, which helps to determine whether the murmur is increasing or decreasing. The Valsalva maneuver can also be used for arrhythmia termination attacks. For example, when supraventricular tachycardia occurs, the Valsalva maneuver can activate the vagus nerve and terminate some tachycardias. The Valsalva maneuver is commonly used in medicine for a variety of diagnostic (right heart echocardiography) and therapeutic (termination of supraventricular tachycardia) scenarios. It can be an active maneuver, or it may occur inadvertently when coughing or defecating.

[0003] The Valsalva maneuver is currently performed clinically under the guidance of physicians, so that physicians can better observe the right-to-left shunt. Due to the different understanding of patients, the degree of effort applied to inhale and exhale may affect the completion of the Valsalva maneuver. If you only hold your breath without trying to breathe, it cannot be considered a Valsalva maneuver. Currently, there is no quantitative standard for the Valsalva maneuver in clinical practice, and it is impossible to ensure that the patient's Valsalva maneuver is standard. As a result, some examinations are not in place, which may affect the diagnosis and subsequent treatment of the disease.

[0004] In recent years, the aging population has increased, and the number of elderly patients receiving surgical treatment has increased. However, due to their special physiological characteristics, the risk of pulmonary complications after surgery, especially laparoscopic surgery, is significantly increased in elderly patients. Valsalva maneuver is a commonly used respiratory function training method, and respiratory function training before surgery is considered to be effective in preventing pulmonary complications. However, the execution of traditional Valsalva maneuver often depends on the patient's self-perception and training experience, and lacks objective and quantitative evaluation criteria. Therefore, it is of great clinical value to develop a visual and quantitative Valsalva breathing training device to standardize the patient's breathing movements. Utility Model Content

[0005] In order to improve the standard level of the Valsalva maneuver in clinical practice and to conduct special training for the Valsalva respiratory function, the present application provides a visual and quantitative Valsalva respiratory function trainer.

[0009] The upper end of the expiratory tube is closed and an air outlet is opened at the upper end. A floating ball is placed in the expiratory tube. When the patient exhales, air comes out of the air outlet and the airflow drives the floating ball to float up along the expiratory tube.

[0011] Furthermore, the air pressure monitoring component is a digital pressure gauge, a mechanical pressure gauge or an air pressure sensor.

[0012] Furthermore, the air pressure monitoring component is an air pressure sensor, the air pressure sensor signal is connected to a controller, and the controller is also connected to a display, and the display is used to display the air pressure value monitored by the air pressure sensor.

[0013] Furthermore, the controller is also connected to a time relay, which is interlocked with the air pressure sensor; the time relay is used to monitor the duration of exhalation or inhalation, and the duration value is displayed on the display.

[0014] Furthermore, the controller is also provided with a communication module, which includes a Bluetooth module and a USB module; the monitored values ​​are uploaded to a host computer through the communication module, and the host computer is a computer, a tablet or a mobile phone.

[0029] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments:

[0030] like Figure 1 As shown, a visualized and quantitative Valsalva respiratory function trainer includes a respiratory main tube 1, which is a T-shaped tube, the horizontal tube head end of the T-shaped tube is connected to a filter 2, the head end of the filter 2 is connected to a respiratory hose 3, and the head end of the respiratory hose 3 is connected to a respiratory mask 4. The vertical tube of the T-shaped tube is connected to an air pressure monitoring component 10 through a threaded structure, and the air pressure monitoring component 10 is used to measure the air pressure of the patient's exhalation or inhalation. The air pressure monitoring component 10 is a digital pressure gauge, a mechanical pressure gauge or an air pressure sensor, which can measure not only positive air pressure but also negative air pressure.

[0031] like Figure 1 As shown, the air pressure monitoring component 10 is a digital pressure gauge; Figure 2 As shown, the air pressure monitoring component 10 is an air pressure sensor. When the air pressure monitoring component 10 uses an air pressure sensor, the air pressure sensor signal is connected to the controller 11, and the controller 11 is also connected to a display 13 and a time relay 12, and the time relay 12 is interlocked with the air pressure sensor; the time relay 12 is used to monitor the duration of exhalation or inhalation; the display 13 is used to display the air pressure value and duration value monitored by the air pressure sensor.

[0032] The tail end of the T-shaped tube horizontal tube is connected with a visualization component, which includes a vertical gas branch tube, an inspiratory catheter 8 and an expiratory catheter 5. The T-shaped tube horizontal tube is connected to the middle of the gas branch tube, the gas branch tube is arranged vertically, and the inspiratory catheter 8 and the expiratory catheter 5 are respectively vertically located on both sides of the gas branch tube.

[0033] The inhalation catheter 8 is a transparent pipe, the upper end of which is connected to the air branch pipe and the lower end is closed. An air inlet 9 is opened at the lower end of the inhalation catheter 8, and a float 7 is placed in the inhalation catheter 8. When the patient inhales, air is taken in through the air inlet 9 and the airflow drives the float 7 to float up along the inhalation catheter 8.

An air outlet 6 is opened at the upper end of the expiratory catheter 5, and a float 7 is placed in the expiratory catheter 5. When the patient exhales, air is discharged from the air outlet 6 and the airflow drives the float 7 to float up along the expiratory catheter 5.

[0035] In order to facilitate the assembly of the device, each pipe is a straight pipe, and the corners or joints are corresponding right-angle elbows or three-way elbows.

The duration of the patient's inhalation can be known based on the suspension time of the float 7, and the air pressure value can be read through the air pressure monitoring component 10. The patient then exhales according to the doctor's instructions. When exhaling, Figure 2 As shown, air is discharged from the air outlet 6 and the air flow drives the float 7 to float up along the exhalation tube 5. The duration of the patient's exhalation can be known based on the suspension time of the float 7, and the air pressure value can be read through the air pressure monitoring component 10.
