Description

lung capacity trainer

technical field

The utility model relates to a medical device for training vital capacity of patients.

Background technique

Breathing is the most important function of the human body, but it is also the most neglected. According to research, the reduction of lung capacity makes people more prone to a variety of diseases that affect lung health in old age, such as bronchitis, asthma, pneumonia, and pulmonary embolism related to lung function degradation, pulmonary fibrosis, Lung tumors, etc.

The so-called vital capacity refers to the total amount of gas that can be exhaled as hard as possible after inhaling forcefully, and it reflects the maximum ventilation capacity during one breath. In addition to incorrect breathing methods that may affect lung capacity, chest or throat surgery may also affect lung capacity, which in turn may lead to lung disease. Therefore, actively performing breathing exercises to exercise the lungs, increase lung capacity, and provide more oxygen to the blood has become a topic that modern people must pay attention to.

However, swimming is the most well-known exercise for exercising lung capacity. However, swimming is not only limited by venue factors, but also due to personal factors. Therefore, not everyone can achieve the goal of increasing lung capacity through swimming. .

Utility model content

Aiming at the above-mentioned technical problems, the utility model provides a lung capacity training device, which is not limited by the venue and is convenient for lung capacity training.

In order to solve the above technical problems, the technical solution adopted by the utility model is: a lung capacity training device, including a cylinder, the front end of the cylinder is connected with an air nozzle for blowing air, and the rear end of the cylinder is closed and provided with a pressure sensor; The cylinder is provided with a piston that can slide back and forth along the cylinder; the piston is connected to the pressure sensor provided at the rear end of the cylinder by a spring; the side wall of the cylinder has a number of axially arranged air holes; the cylinder The body is covered with a shielding cover for covering the ventilation hole; a counter and a controller are also included, and the pressure sensor and the counter are both connected with the controller.

As an improvement, the pressure sensor includes a circuit board and a circuit arranged on the circuit board, and a groove is opened on the upper surface of the circuit board; it also includes a graphene film laid on the opening of the groove, and the graphene film The two ends are provided with electrodes, and the electrodes are connected with the circuit on the circuit board. The biggest feature of the graphene film is that its resistance changes proportionally to the deformation. By using the change of the resistance at both ends of the graphene film, the pressure on it can be calculated.

As an improvement, a battery compartment is also provided at the rear end of the barrel, and a button battery is installed in the battery compartment.

As an improvement, it also includes a mask arranged on the gas nozzle, and the mask is connected with the gas nozzle through a hose.

As an improvement, an alarm device is also included, and the alarm device is connected with the controller.

The principle of the utility model is that the patient uses the air nozzle to blow air into the barrel, and uses the air flow to push the piston to move. The piston is arranged in the barrel to close the vent hole on the barrel. Under the blowing effect of the patient, the piston moves to the rear end, so that the vent hole on the cylinder body communicates with the air nozzle. At this time, due to the lack of air pressure in the cylinder body, the piston rebounds, and an air blowing exercise is completed. Using the shielding sleeve, you can choose to cover a part of the through hole at the front end, so that the piston must be retracted further to connect the rear air hole with the air nozzle, which results in a larger air volume, which is used to adjust the intensity of the exercise. demand users. A pressure value is preset in the controller, and when the pressure sensor senses that the pressure exceeds the preset value, the counter counts once. After the counter reaches the preset number of times, the alarm can remind the user in various ways such as sound and light.

The utility model is beneficial in that the vital capacity trainer with the above structure has a compact structure and is easy to carry, which is beneficial for users to perform vital capacity training anytime and anywhere. At the same time, its sensor has high sensitivity and is convenient for accurate counting. It does not require users to silently count the number of exercises during practice, which greatly improves the convenience of use and is easy to promote.
