Description

An ECMO equipment mounting rack that can be used on the hospital bed

Technical field

The present invention relates to the technical field of ECMO, and in particular to an ECMO equipment mounting rack that can be used on a hospital bed.

Background technique

ECMO is mainly used to treat patients with severe cardiopulmonary failure and provide continuous extracorporeal breathing and circulation to maintain the patient's life.

In current clinical applications, ECMO treatment equipment is generally placed in specific wards, such as ICU wards. When the condition of patients in general wards deteriorates and it is difficult to transfer to these specific wards for treatment, trolleys need to be used to transport these patients. The equipment is moved to the general ward for use. After moving to the ward, the trolley filled with equipment is parked next to the hospital bed for use. For example, the multifunctional medical equipment transport cart disclosed in the patent number CN204956559U has the above uses. This approach also has the following problems. The trolley and the equipment on it, as well as the pulled pipes and wires, will take up a lot of space in the ward, making it inconvenient for medical staff to perform operations or care for patients.

In order to solve the above problems, the invention patent with publication number CN115414209A discloses an extracorporeal life support equipment transportation and placement vehicle. The placement vehicle is equipped with a movable storage rack. After the placement vehicle is moved to the end of an ordinary hospital bed, the vehicle can be The ECMO equipment on the bed is pushed to the hospital bed by the storage rack and the ECMO equipment on the rack. During use, it takes up almost no space on the left and right sides of the hospital bed, making it easier to perform surgery or care on the patient.
