Description

Technical Field

[0001] The present invention relates to the technical field of cardiovascular care transport, in particular to a transport device for cardiovascular care. Background Art

[0002] Cardiovascular care transport devices are specialized transport equipment designed for patients with cardiovascular disease. Their core function is to ensure the stability of patients' vital signs, continuous treatment and monitoring, and reduce transport risks during intra-hospital or inter-hospital transport. The design of cardiovascular care transport devices is centered around patient safety. By integrating stable support, continuous monitoring, and convenient first aid, they minimize the risk of condition fluctuations during transport and provide assurance for intra-hospital or emergency referral of critically ill cardiovascular patients. Existing methods for transferring cardiovascular patients mainly include manual handling and manual transfer boards. However, these methods are all manual operations. During the manual transfer process, the patient's body position will change suddenly, such as turning over and translating from the transfer bed to the hospital bed. This may lead to risks such as severe fluctuations in blood pressure or arrhythmia. It may also easily cause the patient's body to tilt and compress the pipeline, thereby increasing the risk of the pipeline falling off.

[0003] Combining the above problems, we will find that it is difficult to avoid the above problems at the same time when using the existing cardiovascular care transfer device, and even if it can be solved, it needs to be solved with the cooperation of external tools, which makes it impossible to achieve the desired effect.
