The embodiments herein are generally related to the field of medical ventilator. The embodiments herein are particularly related to a ventilator, a controller member and an inflation bag. The embodiments herein are more particularly related to a ventilator and a controller member for operating an inflation bag of a ventilator.
The ongoing time is the time of transmissible diseases outbreak which resulted in pandemic conditions. The pandemic condition causes significant disturbance in economic, social, and political harmony. Statistics related to past pandemics suggest that the likelihood of pandemic conditions may be intensified due to globalization or higher global travel and integration. Multiple outbreaks, notable ones are COVID-19, West Africa Ebola epidemic in 2014, a severe acute respiratory syndrome (SARS) pandemic in 2003, had shown cracks (e.g., early detection of disease, availability of basic medical facility, contacts of infected person, quarantine and isolation procedures etc.) during pandemic circumstances. These unprecedented pandemic circumstances had significantly impacted humanity, claiming many innocent lives and costing billions of dollars. Significant attention has been paid by the international community for development of strategy to alleviate and/rheostat pandemics.
One such strategy to alleviate the challenges of pandemic conditions and similar future problems is to provide sufficient medical ventilators to the humans who got infected by viruses during these unprecedented pandemic times. A conventional medical ventilator needs to precisely deliver an air-oxygen mixture at prescribed oxygen concentrations to the distressed patient's lungs, and the delivery should be carefully made at predefined/prescribed volumes, delivery pressures, and delivery rates. The conventional medical ventilators are built with valves, array of sensors, oxygen concentrators, power backup systems, multi-mode operations, data acquisition, alarms, sophisticated algorithms, electronic controllers etc. to do a complex array of activities in a very sensitive manner by sensing the patient condition and responding to his needs. These components drive up the final cost of the medical ventilator as well as limit large-scale production of the ventilators at a faster rate.
Intermittent Positive Pressure Ventilation (IPPV) is the widely employed method for artificial respiration for the patient experiencing difficulty in performing natural respiration. Ambu bags, commonly known as bag valve masks or manual resuscitators, are simple resuscitators that are most widely used respiratory support equipment in medical emergency situations. Mostly, when a patient who is not in the vicinity of hospital needs breathing support or cardiopulmonary resuscitation (CPR), the bag-valve-mask (BVM) or the Ambu bag is used. The bag-valve-mask (BVM) or the Ambu bag is a self-inflating bag which releases air from one end port when squeezed and sucks air to refill itself with fresh air from another end port, when released. The volume of air pushed into the lungs of the patient when the airbag is pressed is normally referred to as Tidal Volume. The bag-valve-mask (BVM) or the Ambu bag can be operated by pneumatic control using valves or even by motor. In both, inspiration to expiration duration Ratio (IER) is varied by changing “Pause or Stop” duration. Drive motion is not continuous as there is ‘stop’ or ‘pause’ in each cycle. This mechanism requires a special motor like Servo motor, stepper motor, etc. which can be electronically controlled. This increases complexity and cost of the ventilator.
In addition, in certain situations, doctors or nurses may require more accustomed ventilators, and may look to find portable ventilators, in the manner or requirement they prefer.
The above-mentioned shortcomings, disadvantages, and problems are addressed herein, which will be understood by studying the following specifications.

Further, the at-least one controller member 130 is operably configured to slide within the bag holder 150 to change the shape of the inflation bag to vary a tidal volume and an inspiration-expiration ratio of the ventilator 100, without departing from the scope of the present disclosure. The at-least one controller member 130 comprises a first controller member 133 and a second controller member 134. For the sake of brevity, details of the present disclosure that are explained in detail in the description of
In an embodiment, at-least one controller member 130 may be sliding over the bottom wall 153 of the bag holder 150. Firstly, the first inflation bag 102a receives compressed air from the air vessel 101 and the first inflation bag 102a expands. Secondly, the first controller member 133 may slide over the bottom wall 153 of the bag holder 150 thereby contracting one of the second inflation bag 102b, and the third inflation bag 102c. As one of the second inflation bag 102b, and the third inflation bag 102c is pressed against one of the right wall 152 of the bag holder 150 and the second controller member 134, at-least one controller member 130 may change size of the inflation bag 102 by doing contraction and expansion of one of the first inflation bag 102a, the second inflation bag 102b and the third inflation bag 102c of the inflation bag 102. Finally, the air is supplied from one of the contracting bags of the inflation bag 102 to the patient's lungs as per his requirement of fresh air. When at-least one controller member 130 causes expansion of one of the expanding bags of the inflation bag 102, the air comes out of the patient's lungs. The present embodiment ensures that the ventilator 100 uses only one controller member 130 or the arm 130 to operate more than one inflation bag 102 or AMBU bags 102 thereby supplying fresh air to a greater number of patients at the same time.
The moveable member 135 slides over the bottom wall 153 of the bag holder 150 thereby contracting the inflation bag 102. As the inflation bag 102 is pressed against the left wall 152 of the bag holder 150. Therefore, the controller member 130 may change size of the inflation bag 102 by doing contraction and expansion of the inflation bag 102. Hence, the air is supplied from the inflation bag 102 to the patient's lungs as per his requirement of fresh air. Later, the controller member 130 causes expansion of the inflation bag 102, the air comes out of the patient's lungs. The present embodiment ensures that during the usage of the ventilator 100, the user (doctor or nurse) hands remain free thereby giving the user full control to focus on monitoring the patients. For the sake of brevity, details of the present disclosure that are explained in details in the description of
The present disclosure provides a ventilator, such as the ventilator 100. Further, the ventilator 100 of the present disclosure includes at-least one air vessel 101, at-least one inflation bag 102, at-least one connecting member 103, a bag holder 150 and at-least one controller member 130. In particular, the at-least one air vessel 101 may be a compressor 101 for providing pressured air to the inflation bag 102. The at-least one inflation bag 102 is a bag-valve-mask (BVM) or AMBU bag. The bag-valve-mask (BVM) is adapted to be squeezed and expanded. The at-least one connecting member 103 is to connect the air vessel 101 with the inflation bag 102. The bag holder 150 is configured to hold the inflation bag 102. The bag holder 150 comprises a left wall 151, a right wall 152, and a bottom wall 153. The bottom wall 153 connects the left wall 151 with the right wall 152. The at-least one controller member 130 is changing size of the inflation bag 102 by doing contraction and expansion of the inflation bag 102. The at-least one controller member 130 contracts the inflation bag 102 to push fresh air into the patient's lungs, and when the at-least one controller member 130 comes backward, the at-least one controller member 130 expands the inflation bag 102 and air comes out of the patient's lungs.
The present disclosure provides the ventilator 100 that is very simple to use and is cost effective. Also, the present disclosure provides the ventilator 100 that uses only one controller member 130 or the arm 130 to operate more than one inflation bag 102 or AMBU bags 102 thereby supplying fresh air to a greater number of patients at the same time. Moreso, the present disclosure provides the ventilator 100 that may be operated without a power (electricity).
The present disclosure further provides the ventilator 100 which does not require highly skilled professionals for its operation. Also, the present disclosure further provides the ventilator 100 which is portable and lightweight.
