Medical casters are different from ordinary casters. They are mainly used for medical equipment and are important tools for medical staff. The quality of the tool affects the life safety of the patient. Equipment such as hospital beds, ambulance beds, wheelchairs, B-ultrasound, and medical vehicles require casters. Sudden abnormalities during driving can cause varying degrees of injury. For example, when the ambulance bed is transporting patients at high speed, the caster of the medical device suddenly breaks, and the patient falls due to inertia, which is definitely worse for emergency patients. In order to improve the safety of medical equipment, medical caster manufacturers need to extend the service life of casters.
1. Dynamic load: It is strongly recommended that the load design standard of the caster is 1/3 of the total load of the mobile device and equipment.
2. Caster and tire materials. The single wheel structure is flexible, with small starting force and rotation force, but a double wheel design with strong load-bearing capacity and high stability should be selected.
3. Generally speaking, large-diameter casters are easier to roll and control than small casters. Use soft treads for hard ground and hard treads for soft ground or carpet wheels.
4. The rotation structure of the medical caster bracket has a great influence on the use of the equipment. Generally speaking, the ball bearing slewing bearing structure is flexible and noiseless, which is suitable for low-load and frequently moved equipment. Compared with the single ballast, the double rotation structure has good stability and is suitable for small mobile medical equipment.
5. The caster environment is also an important factor to consider. Most casters are equipped with steel brackets. Galvanized or chrome-plated to prevent rust. In corrosive environments, casters or plastic-covered casters are recommended.
Designers usually strike a balance between safety, clinical requirements, practical use and price. Non-medical casters can also be used for medical devices as long as they meet relevant standards and requirements.
The choice of casters should also consider the use environment. In general, the medical device environment is not as harsh as the industry, because the hospital itself has specific requirements for temperature, humidity and cleanliness.
After the anti-dumping of medical casters is completed, medical devices will be safer to use. There are many types of medical devices and the use environment is more complex. An unstable center of gravity can lead to tipping problems, equipment damage, and injuries to patients and medical staff. For example, if the B-ultrasound detector accidentally hits someone, it will fall due to the unstable center of gravity, causing certain economic losses, not to mention that the collision is very dangerous... Adding anti-dumping design to medical casters can further improve the stability and safety of medical devices. For medical staff, such a design will make it easier for them to use the equipment. Applicable to medical caster manufacturers
When conducting anti-dumping design, medical caster manufacturers need to integrate the overall structure of medical devices, including the height, weight and shape of medical devices. However, when observing many medical casters with anti-fall functions, it is found that many anti-fall groups such as rollers, connecting rods, and fixing plates are installed at the bottom of the equipment to improve the anti-fall performance. My understanding.
