Medical equipment handle loading device

Medical equipment handle loading device

The medical equipment handle loading device is a specialized device used to test the strength and stiffness of handles or handles, to ensure that these devices can withstand necessary mechanical stresses during daily use and transportation, effectively test the tensile strength and stability of handles, and ensure the safety of medical equipment during use.

The safety and effectiveness of medical equipment are directly related to the life safety of users. Strengthening the supervision and management of medical equipment to ensure its safety and effectiveness It is crucial to standardize the production and use of medical equipment and ensure the personal safety of doctors and patients. GB9706.1-2020 standard 9.4.4c specifies medical equipment Including any joint hole basin and parts of its various components The door should have sufficient strength and rigidity. Therefore, the handles or handles on portable devices should also undergo corresponding loading tests.

2. Technical parameters

4.5 Complete set of testing equipment (users need to provide the dimensions of ME equipment)

4.6 Control mode: The human-machine interface adopts a touch screen. User friendly interface

4.7 Experimental setup: (customized according to the size of the user's ME equipment)

4.8 The car is movable and fixed separately from obstacles during the experiment

4. Configuration

4.1 Tooling: 1 set of aluminum profiles, aluminum alloys, hardwood, cement board (solid wood board), stainless steel, rollers, nylon, etc

4.2 Servo motor/ball screw/control box/control circuit/software: 1 set each

4.3 Control PLC/True Color Touch Screen: 1 set each

The workflow of the controllable medical equipment handle loading test device is as follows:

5.1 Move the standby side equipment to the bottom of the bracket and hook the handle with a hook. At this time, the electric control box controls the motor to start and lifts the handle of the medical equipment; When the equipment is not in contact with the limit device, the tension sensor reads the weight of the equipment, and then automatically inputs the measured value of the tension sensor to be tested based on the weight. It can also be manually inputted. Generally, the measured value to be tested is 4 times the weight of the equipment to be tested;

5.2 Motor driven tension sensor lifting equipment, with limit devices blocking the movement of the equipment; When the WRI gear of the limiting device is in motion, the motor still removes power until the measurement position of the tension sensor reaches the measured value to be tested (gradually increasing from zero to the test value within 10 seconds):

The electric control box controls the motor to maintain output power Maintain the measurement value of the tension sensor at the measured value to be tested for a period of time (standard specified as Imin);

5.3 Stop the output power of the motor and remove the equipment. During this process, if the handle of the equipment is damaged, it will be marked as an unqualified product; If there is no damage, it is marked as a qualified product.

6. Main functions

Assisted handling: With a handle design, medical staff can easily grasp and move equipment.

Stability guarantee: Ensure that the equipment remains stable during movement, preventing tipping or damage.

Reduce burden: Reduce the physical exertion of medical staff when carrying heavy objects and lower the risk of occupational injury.
