technical field

The invention relates to a transfer device for a patient or a disabled person, more specifically, to a plate-type patient transfer vehicle.

Background technique

With the technological development of artificial intelligence and automation, medical equipment also needs to keep pace with the times. At present, there are a large number of limb paralyzed patients and inpatients who cannot walk around in the hospital. These critically ill patients have to undergo various examinations every day, and transfer vehicles between wards, examination rooms or operating rooms must be used to transfer patients from the hospital bed. The transfer car is sent to the examination bed or operating table. This kind of transfer process requires someone to help lift it. Nurses are mostly women with poor arm strength and physical strength. In case of obese patients, lifting is more difficult and makes the patient suffer. Therefore, in this case, almost all family members are dispatched, and parents and children will suffer great pain, which not only wastes a lot of manpower, but may also cause secondary harm to patients.

The existing Chinese patent application number 201510619149.2, the application publication date is December 2, 2015, and the name of the invention is: prone position human body shovel carrying bed, the application involves a shovel carrying bed, including a bed frame and foot rollers , the foot rollers are arranged on the four corners of the bottom surface of the bed frame, and also include a number of bed surface fixing plates, a number of bed surface shovel plates, a translation mechanism and a lifting mechanism, and a number of bed surface fixing plates are arranged on the top surface of the bed frame in parallel at intervals. And supported by the support rods of the bed frame, several bed surface shovels are located in the gaps between the several bed surface fixed plates, the translation mechanism and the lifting mechanism are respectively arranged on the bed frame, and the translation mechanism drives the plurality of bed surface shovels to translate synchronously, The elevating mechanism drives the several bed shovels to elevate synchronously. This application can reduce the use of manpower during transfer to a certain extent, but it is very inconvenient in actual operation. In the process of inserting the bed surface shovel plate under the patient's body, many people need to lift the patient off the bed surface of the hospital bed, otherwise the It can shovel and injure the patient, causing secondary injury to the patient, and this process of lifting the patient off the bed surface by many people may also cause secondary injury to the patient, and waste a lot of manpower.
