A Hospital Bed is a type of Nursing bed. To put it simply, a nursing bed is a bed that can help nurses perform nursing care, and its functions are far more than what we commonly use.

Cause analysis and rectification measures of hospital bed failure
Hospital Bed has the highest failure rate: guardrails, static point devices, bed wheels, and bed legs. Analyze the causes of these three types of failures and implement repairs and improvements.
1. Reason analysis of guardrails
Among the guardrail faults, the component with the highest occurrence rate is the guardrail handle seat. Through the analysis of the cause of the failure, it is found that because some manufacturers use the handle seat of the guardrail to fix it with a pull rivet, the material of the pull rivet is metal aluminum, the texture is relatively soft, and it is easy to fall off after long-term use and wear. Once the fixed rivets fall off, it will directly cause patients and medical staff to pinch their fingers when operating the guardrail.
We improved the machine screws to replace the blind rivets. The advantages of machine screws are: firstly, the wear resistance is much higher than that of rivets; secondly, mechanical screws can increase the mechanical screw fixing bite by adding gaskets, spring pads, and self-locking nuts, to prevent the guardrail handle from falling off again.
2. Cause analysis of point devices
The failure rate of static point devices accounts for 30.7% of the total faults, and there are two main damage parts of static point devices. Through the analysis of the reasons, it was found that due to the frequent violent insertion and extraction of the static point frame rod, or the oblique force insertion and extraction, the static point frame sleeve fixing screws were loosened and deformed.
Improvement measures are timely inspection and maintenance. During the inspection of the bed unit, if the static point frame rod is found to be tilted or shakes greatly, fix the screws in time or replace or repair the static point frame sleeve. At the same time, on-site demonstration operations are performed for clinical users or patients and their families, and the correct insertion and removal methods and usage specifications of static point rack rods are explained in detail.
Analysis of other causes
Damage or failure of bed wheels and bed legs can easily cause patients to fall off the bed and be injured by bumps, which is related to the personal safety of patients and the quality of medical care. Among such failures, 15.1% were due to broken bed wheel screws. After analyzing the cause of the failure jointly by several mechanical engineers, it is considered that the screw wheel of some Hospital Beds is thin and has poor wear resistance. After long-term use, especially during the transfer process, a slight violent operation will cause the bed wheel screw to break.
Our improvement measure is to improve the screw wheel. After many studies and experiments, we not only increased the load-bearing capacity of the bed but also avoided the breakage of the bed wheels.
