The ocs system is a safety feature that is used to detect if the front passenger seat is occupied and to automatically deactivate the front passenger air bag. This feature is designed to protect small children from injury or death if the air bag inflates in an accident and they are not properly restrained.
The global ocs system market is expected to grow over the forecast period. Rising awareness about car safety among automobile consumers has prompted automakers to incorporate the ocs system in their vehicles. In addition, growing demand for occupant classification systems in autonomous vehicles is expected to drive the global market. However, high prices associated with the installation of ocs systems in cars may hinder the market growth.
There are many different types of ocs systems. They can be classified based on their components, applications and vehicle type. By component, the ocs system market is segmented into pressure sensor and seat belt tension sensors. The pressure sensor is estimated to hold the largest share in the ocs system market. This is due to increasing adoption of smart airbags and 3 point seat belts in mid-size light-duty vehicles worldwide.
On the other hand, seat belt tension sensors are gaining popularity for their capability to detect the amount of stress placed on the seatbelt in an accident. These sensors are usually located in the seat frame, and they can be connected to a vehicle’s onboard diagnostics (OBD). They are designed to monitor the status of the vehicle’s safety features. The ocs system market is also classified by vehicle type. The market is divided into light-duty and electric vehicle type. The light-duty category is further split into economy, mid-size and luxury vehicles. The electric vehicle type is further divided into battery electric and hybrid electric vehicles.
A new method for preserving donor hearts in beating condition with OCS has the potential to reduce underutilization of less-than-ideal transplantable organs. This method, in combination with other reconditioning therapies, could allow for longer cold storage times and improved donor-recipient matching. Moreover, the OCS system could potentially prolong ischemic time by perfusing the heart with a solution at 34degC during transport.
The institution of myocardial perfusion on the OCS machine is illustrated in Figure 1. After the heart is put on the tray with the left ventricle facing anteriorly, an LV vent is inserted through the mitral valve and sutured to the left atrial wall. Once the heart starts beating, pacing wires are placed (A). Finally, the pulmonary venous cannula is connected to its respective spout and the transparent lid of the OCS tray is closed (B).
After connecting the aortic cannula to the OCS machine, the coronary flow is established at around 700-800 ml/min. The pulmonary cannula is vented to the OCS trays spout while the aortic pressure is controlled by the solution rate. Once the coronary flow is stable, a sterile plastic covering is placed over the OCS tray and the lid is closed (C). The OCS tray contains an oxygen tank that can be filled with oxygen to prevent any air leaks during transport.
