Description

Technical Field

[0001] This invention relates to medical care technology, and more particularly to a pneumatic call triggering device. Background Technology

[0002] Currently, with social development and progress, and the improvement of people's living standards, the demand for caregivers is increasing, and the requirements are also getting higher. More and more migrant workers are entering the caregiver industry. In hospitals, communities, or homes, many patients receive services provided by caregivers. Emergency call devices are electronic information exchange devices used by hospitalized patients to call doctors and nurses. They have great practical value and have been widely used in hospitals of all levels to facilitate communication between patients and nurses.

[0003] Patent document CN202023093213.3 discloses an emergency call device for medical care, including a housing and a connecting plate. The emergency call device body is fixedly connected inside the housing, and a main unit is fixedly connected to the upper surface of the telescopic emergency call device body. A main motor is fixedly connected inside the main unit, and a main rotating shaft is rotatably connected to the outer wall of the main motor. A gear is fixedly connected to one end of the main rotating shaft. A groove is provided on the back of the housing, and a sliding groove is provided on the outer wall of the connecting plate. A toothed groove is provided on the inner wall of the sliding groove. The main motor inside the housing drives the gear to rotate, which, in conjunction with the toothed groove on the connecting plate, causes the emergency call device to move towards the housing, away from medical staff and patients. This prevents accidental contact by medical staff or patients when the emergency call device is not in use, which could cause the emergency call device to issue a false alarm or even damage the device.

[0004] Patent document CN202020530814.7 discloses a timely call device for medical bedside care, which is equipped with an anti-fall mechanism to protect the timely call device from the risk of falling and damage, effectively protecting the device and improving its stability. It includes a call machine, a switch groove, a sliding switch, a number dial, number buttons, a call button, a microphone, an anti-fall inner sleeve, a spring, and an anti-fall outer shell. The call machine contains a power supply and a circuit board. A switch groove is located on the lower left side of the front of the call machine. The sliding switch is slidably mounted inside the switch groove and electrically connected to the circuit board. The number dial is located on the lower center of the front of the call machine. Multiple sets of number buttons are evenly arranged inside the number dial and electrically connected to the circuit board. The call button is mounted below the number buttons and electrically connected to the circuit board. The microphone is located below the call button. The anti-fall inner sleeve frame is mounted around the outer perimeter of the call machine.

[0005] The aforementioned patent documents, in conjunction with existing technology, reveal the following shortcomings of current pneumatic call triggering devices: In existing nursing call extensions, the input device is usually a hard button. Pressing this button requires a lot of force to enable the extension to communicate with the main unit. For some patients with weak hands or hand tremors, it is difficult to press this type of button. In case of an emergency, if the extension cannot establish communication with the main unit when it is necessary to call medical staff for assistance through the nursing call extension, it will lead to delays in treatment.

Slightly pressing the flexible pressing device causes airflow to flow along the connecting hole, lifting the push button so that the push button contacts the trigger position of the PCB board. When using this device, the user can deform the flexible pressing device by squeezing or touching it, causing the gas inside to flow towards the connecting hole. This airflow drives the push button to contact the trigger position on the PCB board, thereby triggering the switch. Deformation occurs with relatively little force, making it easy to transmit call information. This effectively avoids the problem of insufficient pressing force, resulting in higher transmission efficiency and safety. Attached Figure Description
