Description

Technical Field

[0002] Patients with digestive tumors require extra attention during care, especially when resting in bed. Bedside guards are auxiliary devices specially designed to improve bed safety and are mainly used in digestive tumor care because they can effectively prevent users from accidentally falling from the bed while ensuring their comfort and freedom of movement.

[0003] In the existing technology, firstly, it is difficult to adjust the guardrails of some devices according to the needs of patients, which affects the convenience and safety of use. The stability of the guardrails will be affected, which may cause the entire device to shake during use, increasing safety hazards. Manually adjusting the position of the guardrails will be more difficult, increasing the labor intensity of the operator. Secondly, the installation process of the guardrails and the bed body of some devices is complicated, time-consuming and labor-intensive. The connection between the device and the bed body may not be strong enough and is easy to fall off or shift during use. It is quickly disassembled in an emergency. The lack of this mechanism may affect the rapid response in an emergency. Finally, the maintenance and repair of some devices are more difficult, increasing maintenance costs. Utility Model Content
