Breathing aid

This creation is about an assisting device, especially a breathing assisting device that can strengthen the inhalation and exhalation of the patient's local area.

In the process of cardiac surgery, patients usually reduce the alveolar ventilation to increase the operable field of vision of the surgeon during the operation. Therefore, patients generally have incomplete lung expansion after surgery. In addition, the cough, sputum, and deep breathing caused by wound pain are easy to cause pulmonary complications after the patient's surgery, and the patient's breathing pattern changes from about 6 to 10 spontaneous deep breaths per hour It is a shallow and fast breathing pattern, which in turn causes alveolar collapse. However, the existing electronic phlegm clothing adopts pneumatic tremor, so it is not suitable for the treatment of patients with the above-mentioned conditions.

In order to make the above-mentioned and other purposes, features and advantages of this creation more obvious and understandable, the preferred embodiments of this creation are specifically described below, and in conjunction with the attached drawings, detailed descriptions are as follows:

Please refer to FIG. 1, which is a preferred embodiment of the breathing assistance device of the present invention, which includes a covering body 1, at least one pressure sensing unit 2, a inflation and deflation module 3, and a processing unit 4 The pressure sensing unit 2 and the inflation and deflation module 3 are located in the cladding body 1, and the processing unit 4 is coupled to the pressure sensing unit 2 and the inflation and deflation module 3.

The covering body 1 is used for patients who need to train breathing ability. The covering body 1 can in principle cover at least the chest of the patient. The appearance of the covering body 1 is not limited in this creation; In this embodiment, it is explained in the form of a vest with a cardigan, so that the covering body 1 can be easily put on and taking off, and by covering the back part of the patient, the part covering the chest of the patient can be maintained Close to the patient's chest. The covering body 1 has an inner surface 11 facing the chest of the patient, and the covering body 1 has at least one air bag 12 inside. This creation can be used to repeatedly inflate and deflate the airbag 12 to manipulate the patient's proprioceptive stimulation, thereby inducing the patient's deep breathing action, and expanding and squeezing the chest during inflation to promote long exhalation. In this embodiment, the number of the at least one air bag 12 may be six, and the upper, middle, and lower lung lobes located on the left and right lungs, respectively.

Preferably, the covering body 1 may further include an adjusting member 13 for adjusting the fit of the covering body 1 to the patient's body. For example, without limitation, the adjusting member 13 may be a belt or a devil's felt.

The at least one pressure-sensing unit 2 can be coupled to the inner surface 11 of the covering body 1, and locate a pressure value between the airbag 12 and the patient's chest for the airbag 12 located above. Among them, the number of the pressure sensing units 2 preferably matches the number of the aforementioned airbags 12, so the number of the pressure sensing units 2 in this embodiment can also be selected as six, which can be sensed by the six pressure sensing units 2 respectively The pressure value between the corresponding airbag 12 and the chest of the patient is measured to accurately control the pressure value between each airbag 12 and the chest of the patient. For example, but not limited to, the pressure sensing unit 2 may be a MEMS pressure sensor.

For example, the inflation and deflation module 3 can be a pneumatic pump. Among them, the number of the catheters 31 preferably matches the number of the aforementioned balloons 12, so the number of the catheters 31 in this embodiment can also be selected to six, so that each catheter 31 communicates with the corresponding balloon 12, and Inflate and deflate.

In detail, when the inflation and deflation module 3 deflates the airbag 12, if the change in the pressure value sensed by the pressure sensing unit 2 does not show a continuous decrease, it means that there is sputum production in the lung lobe .

According to the above, in order to expel the sputum from the lung lobes of the patient, the processing unit 4 controls the inflation and deflation module 3 to repeatedly deflate and inflate the balloon 12 repeatedly, so that the lung lobes to which the balloon 12 is positioned can be borrowed The exhalation air flow is induced by the pressure, so that the sputum attached to the lung lobe bronchial tube wall enters the trachea, and then the sputum is expelled from the body by coughing.

On the other hand, when the number of the airbags 12 is several, the number of the pressure sensing units 2 and the catheter 31 is the same as the number of the airbags 12, each pair of the pressure sensing units 2 is located in each of the airbags 12, each Each of the catheters 31 has a valve 32, and each of the valves 32 is coupled to the processing unit 4, and is used to open or close each of the catheters 31 to control the communication state of the inflation and deflation module 3 and each of the airbags 12. In this embodiment, each valve 32 is a solenoid valve. When the processing unit 4 controls the inflation and deflation module 3 to deflate each of the airbags 12, where the change amount of the pressure value sensed by the pressure sensing unit 2 does not show a continuous decrease, then the processing unit 4 Control the valve 32 in the catheter 31 corresponding to the airbag 12 of the pressure sensing unit 2 to open, and control the valve 32 on the remaining catheter 31 to close, and the airbag 12 with the valve 32 open can repeatedly deflate and inflate , So that the lung lobe where the balloon 12 is positioned can induce the expiratory airflow by pressurization, so that the sputum attached to the bronchial tube wall of the lung lobe enters the trachea, and then the sputum is expelled from the body by coughing.
