Field of the medical stretcher

Description of the medical stretcher
A stretcher is for carrying a sick person or an injured person with a litter placed thereon. Particularly, when a patient complains of an ache, even a small vibration amplifies the ache. In an up/down slide system of a conventional stretcher, a lock mechanism of oil spring is adopted. When locking, a pin is inserted into a hole and thereby the up/down slide system is locked at a given position. In the above system, stop positions are restricted to several steps. Additionally, while sliding up/down the stretcher, sometimes it takes a long time to fix the stretcher since the pin is hardly inserted into the hole; the pin is hardly pulled out; or it may stop halfway to cause a malfunction, resulting in a sudden lowering of the stretcher. As a result, sometimes pain and uneasiness may be rendered to the patient while sliding up/down the stretcher.
A sick person or injured person is apt to feel strong uneasiness and sensation of fear by just being laid down on a litter placed on a stretcher. In order to relieve such uneasiness and sensation of fear as described above as far as possible, it is desired to provide such stretcher that slides up/down smoothly and is capable of being fixed at any position.
An object of the medical stretcher is to provide a stretcher equipped with a non-step stopper mechanism capable of changing the height of a stretcher up/down smoothly in a non-step manner without rendering pain or uneasiness to a patient.
