The invention relates to medical auxiliary rehabilitation equipment, in particular to an exhalation exerciser.

Background technique

In recent years, respiratory system disease is a common disease and frequently-occurring disease. The mortality rate in cities is the third, while in rural areas it is the first. In recent years, due to air pollution, smoking, population aging and other factors, the morbidity and mortality of chronic obstructive pulmonary disease, bronchial asthma, lung cancer, pulmonary diffuse interstitial fibrosis, and pulmonary infection at home and abroad have been reduced. Unabated. It is very necessary to carry out air blowing exercises in the early stage, which can reduce the occurrence of atelectasis, hypostatic pneumonia and other diseases, and help the recovery of the disease. On the other hand, for long-term bedridden patients, patients after major surgery, and patients with medical diseases, more and more attention has been paid to their respiratory function exercises. If such patients do not do respiratory function exercises, some diseases are not directly related to the lungs, but long-term illnesses will hinder the complications of lung diseases. At present, there are countless patients with diseases that have nothing to do with lung diseases, who eventually die or leave serious sequelae or prolong the course of disease due to lung diseases. Therefore, early respiratory function exercise is very necessary, especially for patients with lung diseases.

chronic obstructive pulmonary disease Pulmonary diseases (COPD) is a devastating lung disease characterized by airflow limitation that is not fully reversible. Airflow limitation is usually progressive and is associated with an abnormal inflammatory response of the lungs to noxious particles or gases. When there is chronic, nonspecific inflammation of the terminal bronchial tube wall for a long time, the terminal bronchial tube wall softens over time. The terminal bronchus is connected to the alveoli. When softened to a certain extent, the wall of the terminal bronchi will collapse earlier than the alveoli when the patient exhales, thereby closing the airflow channel, and the carbon dioxide in the alveoli cannot be discharged. Because there is a large amount of carbon dioxide trapped in the lungs during inhalation, more fresh air cannot be inhaled into the lungs, which cannot meet the needs of the body. This will aggravate the patient's hypoxia, which will cause the patient to have difficulty breathing, which is the pathology of COPD. If the patient is hypoxic for a long time, it will cause damage to other systems of the patient, and the treatment of this disease is a long process. Therefore, in the process of treatment, our first priority is to solve the patient's long-term hypoxia and respiratory muscle fatigue. To solve this problem, the patient must be allowed to perform respiratory function exercise. At present, the common method in the hospital is to use a non-invasive ventilator to provide patients with positive end-expiratory pressure, so as to ensure a certain pressure in the airway throughout the breathing cycle, so that the terminal bronchi will not collapse prematurely. The non-invasive ventilator is too bulky and expensive, and cannot be carried. Or instruct the patient to take a deep breath effectively, but this effective deep breathing instruction is time-consuming and laborious, and it is also very difficult for the patient to learn. Or asking the patient to blow up a balloon is not very practical either. There are also some hospitals that are currently doing simple breathing exercises to patients, using a tube to place one end in the water 5 to 10 cm deep, and allowing the patient to blow air from the other end. These make the patient unable to grasp the strength of blowing. Many patients think that the stronger the blowing force, the better, but this is wrong. If the blowing is not good, the effect will be counterproductive.

detailed description

The exhalation exerciser includes a main cavity and an air outlet, a blow force control device installed in the main cavity and a force control spring connected with the blow force control device, and the blow force control device is used to control and judge the blowing force of the patient. strength.

The exhalation exerciser shown in Figures 1 to 6 includes a mouthpiece 1, an embolus tube 2, a main cavity 3, an air outlet 4, a force control spring 5 and a blow force control device. The mouthpiece 1 , the embolic tube 2 and the main cavity 3 are hermetically connected together sequentially, and the air outlet 4 is located at the other end of the main cavity 3 opposite to the mouthpiece. Control force spring 5 links to each other with blowing force control device. In the embodiment shown in Figures 1 to 7, the blow force control device includes a plug and a baffle connected to the plug. In the embodiment shown in FIGS. 1 to 6 , the blow force control device at least includes a first plug 6 and a first stopper 8 connected to the first plug 6 . The first emboli may include one or more. The initial position of the first blocking piece 8 (that is, when the air is not blown) is located at the air outlet channel opening 21 of the embolic cylinder 2, and covers the air flow passage of the air outlet channel opening. As shown in Figure 6, two sockets 61 for inserting the first embolus 6 are provided on the inner wall of the embolus barrel 2, and when the embolus moves left and right with the blow force control device, it moves from the mouthpiece to the air outlet in the hole. During the maximum range of movement, the embolus 6 also partially remains in the jack. When the patient blows air with the mouthpiece 1 in his mouth, the blown gas pushes away the first flap 8 that is close to the air outlet channel opening 21, so that the air flow enters the main cavity 3 smoothly and is released from the air outlet 4. Because the blow force control device is connected with the force control spring, by arranging the elastic force of the force control spring, only when the strength of the patient's air blowing is greater than the elastic force of the force control spring can the flap be blown. As shown in Figure 3, if the blowing force of the patient is too large, the baffle 9 will be blown to the air outlet 4, and the baffle 9 will close the air outlet, causing the exhaled airflow to be unable to be discharged smoothly. The patient is therefore prompted to reduce the insufflation force. Thereby effectively controlling the blowing strength of the patient and realizing effective exhalation exercise. When an exhalation movement ends, the compressed or stretched force control spring resets to the initial state when there is no pressure or the pressure is less than the elastic force, and drives the first blocking piece to also move to the initial position.

In the embodiment shown in Figures 1 to 3, the exhalation exerciser includes a mouthpiece 1, an embolus barrel 2, a main cavity 3, an air outlet 4, a force control spring 5, a blow force control device and a spring barrel 51 .

The second emboli 7 is connected to the second blocking piece 9 . The spring barrel includes a force control spring, one end of the force control spring 5 is connected to the second plug 7, and the other end is installed on the inner top of the spring barrel. At the initial position, the distance between the second blocking piece 9 and the air outlet 4 is smaller than the moving distance of the first embolus 6 in the embolus barrel 2 . This can ensure that when the second baffle 9 is blown to the air outlet 4, the emboli 6 still partially remain in the emboli tube, and the emboli tube can still support the first baffle.

In the embodiment shown in FIG. 4 , the exhalation exerciser includes a mouthpiece 1 , an embolus barrel 2 , a main cavity 3 , an air outlet 4 , a force control spring 5 , a blow force control device and a spring barrel 51 . The mouthpiece 1, the embolus barrel 2, the main cavity 3 and the spring barrel 51 are sequentially and airtightly sleeved together. The blow force control device includes a first plug 6 and a first blocking piece 8 connected with the first plug 6 . The second emboli 7 is connected to the first blocking piece 8 . One end of the force control spring 5 is connected with the second plug 7, and the other end is fixedly installed on the inner top end of the spring barrel. At the initial position, the distance between the first blocking piece 8 and the air outlet 4 is smaller than the moving distance of the first embolus 6 in the embolus barrel 2 . This can ensure that when the first baffle is blown to the air outlet, the embolic tube can still support the first baffle.

In the embodiment shown in FIG. 5 , the exhalation exerciser includes a mouthpiece 1 , an embolus tube 2 , a main cavity 3 , an air outlet 4 , a force control spring 5 and a blow force control device. The mouthpiece 1 , the embolic tube 2 and the main cavity 3 are hermetically connected together sequentially. The blow force control device includes a first plug 6 and a first blocking piece 8 connected with the first plug 6 . One end of the force control spring 5 is connected to the first embolus 6 , and the other end is fixedly installed on the inner top end of the embolus tube 2 . At the initial position, the distance between the first blocking piece 8 and the air outlet 4 is smaller than the moving distance of the first embolus 6 in the embolus barrel 2 . This can ensure that when the first baffle is blown to the air outlet, the embolic tube can still support the first baffle.

In order to show the effect of blowing air, an airflow prompting device through which the airflow passes through the air outlet is provided at the air outlet 4, and the airflow prompting device can be a fan, a whistle, a light and other devices. In the embodiment shown in FIGS. 1 to 7 , the fan 41 is arranged at the end of the air outlet 4 . When gas flows out, the gas drives the fan to run.

The exhalation exerciser shown in FIG. 7 includes a mouthpiece 1 , a main cavity 3 , an air outlet 4 , a force control spring 5 , a blow force control device and a spring barrel 51 . The mouthpiece 1 , the main cavity 3 and the spring barrel 51 are sequentially and airtightly sleeved together. Wherein the blow force control device includes a second plug 7 and a first blocking piece 8 connected with the second plug 7 . The spring barrel includes a force control spring, one end of the force control spring 5 is connected to the second plug 7, and the other end is installed on the inner top of the spring barrel. The patient breathes in gas from the blowing port 11 of the mouthpiece, the gas pushes the first flap, and the breathed gas leaves the exhalation exerciser through the gas outlet 4 .

The exhalation exerciser shown in Figures 8 to 9 includes a main cavity 3, a blow force control device installed in the main cavity, and a force control spring 5 connected with the blow force control device. In this embodiment, the blow force control device is a blocking plate 8 . The main cavity 3 also includes an air outlet 4. Before blowing, the baffle is located at the air outlet (as shown in Figure 8) or between the air blowing port 11 and the air outlet 4, and the gas between the air blowing port and the air outlet Not in circulation. When inflating, when the blowing force of the patient is greater than the pressure of the spring, the baffle is blown and no longer blocks the air outlet (as shown in Figure 9), or the gas is circulated between the insufflation port and the air outlet, so that the air It can come from the air outlet and blow the fan to rotate.

The exhalation exerciser as shown in Figure 10 includes a main cavity 3, an air outlet 4 installed on the main cavity 3, a blow force control device installed in the main cavity, and a force control spring connected to the blow force control device 5. In this embodiment, the blow force control device is a blocking plate 8 . One end of the spring is connected to the blocking piece 8 , and the other end of the spring is connected to the spring barrel 51 . In one embodiment, the spring barrel 51 is screwed into the main chamber 3 . When a larger exhalation force is required for training, the spring barrel is more screwed into the main cavity, so that the spring will generate a larger elastic force after being compressed. When training with less exhalation force, the spring barrel is less screwed into the main chamber. Any way of adjusting the spring pressure belongs to the design solution of the present invention. Before blowing, baffle plate 8 has blocked air outlet 4. After the baffle plate 8 is blown, the gas flows out from the gas outlet. In this embodiment, a whistle is installed at the air outlet.

When the patient performs exhalation exercise, the gas is blown in from the blowing port 11 of the mouthpiece, and the flap is pushed to move. The air will leave from the air outlet through the main cavity.

In the embodiment shown in Figures 1 to 7, when the blowing force is too large and the baffle moves to the bottom of the main cavity, the baffle will block the air outlet, and the exhaled gas cannot flow out from the air outlet, that is The exhalation exerciser can't blow out the gas. In one embodiment, the blowing force required for blowing the baffle until the baffle separates from the embolic cylinder and blowing the baffle until blocking the air outlet is set to be no greater than 3 cmH ₂ O. A fan is set at the air outlet 11, and the rotation of the fan shows that the gas has been exhaled. In one embodiment, the air outlet is circular, when its diameter is around 5 to 8 mm. This not only ensures a certain pressure in the airway, but also props up the collapsed alveoli in the lungs, improves the utilization rate of the alveoli, and also allows the patient to reduce the blowing force when the blowing force is not too high, that is, the blowing force will not be too high. Not too low either.

Due to the principle of airflow dynamics, certain shocks can be produced during the blowing process, and the pressure in the airway will also have certain shock changes, which is conducive to the loosening of sputum in the lungs, improving the rate of sputum excretion, and reducing lung infections. And under the resistance of the vibration frequency, carbon dioxide is more conducive to discharge. In one embodiment, a spring adjustment device is provided to adjust the elastic force of the spring according to the patient's condition, so that the patient's air blowing is more in line with the condition of the patient at that time. For example, according to the patient's condition, the size of the blowing resistance can be adjusted by adjusting the elastic force of the spring. For example, an adjustable spring barrel can be set on the spring barrel at the tail to change the compressed degree of the spring to adjust the size of the resistance when blowing, and an indicator mark is printed on the spring barrel to represent the size of the resistance. The initial blowing force is generally above 3 to 5 cmH ₂ O. The resistance to the movement of the blow control device is adjusted by adjusting the length of the spring.

Two emboli connected on the blocking plate can prevent the blocking plate from swinging left and right when the piston moves.

In one embodiment, the piston is made of plastic material, and its front and rear ends are respectively provided with a first blocking piece and a second blocking piece made of the same rubber material. The spring selection has specific potential energy, the spring is fixed on the spring barrel, and the rest are all plastic materials.

In one embodiment, the exhalation exerciser is connected with a lanyard and can be hung around the neck, so that the exhalation exerciser can be used at any time for exhalation training when necessary.

The method for performing exhalation exercise using the exhalation exerciser of the present invention includes the following steps: first take a deep breath, then blow gently until the flap is blown, and the blown air will leave the exhalation exerciser through the air outlet . When the blowing force is too small, the gas circulation between the blowing port and the gas outlet is blocked by the baffle, and no gas is blown out. If the blowing force is too large, the baffle is blown to the air outlet, blocking the air outlet, and the gas cannot be blown out. Therefore, the air will be blown out just within the range of the required blowing force, so that the blowing force will neither be too small nor too large. It should be emphasized that blowing is not about blowing fast or blowing much, but about choosing the appropriate blowing force. Generally, blow 5 to 6 times a day, according to the doctor's instructions, blow 5 to 6 breathing cycles each time, or perform blowing training when you feel chest tightness. Don't be too reluctant, patients should do what they can according to their physical condition. Utilizing the exhalation exerciser of the present invention to perform respiratory function exercise plays an important role in the treatment of respiratory distress syndrome, non-cardiogenic pulmonary edema and pulmonary hemorrhage. The breath exercising device of the present invention is small in size and convenient to place and carry.
