Description

Patient three-dimensional static transfer vehicle

The utility model relates to a vehicle for statically transferring a patient by using a three-dimensional space, which belongs to the technical field of medical instruments. Background technique

At present, the flat car used by the transporter can only operate in a two-dimensional plane. Because of the large footprint and inflexibility, it is very inconvenient to use in a small space. From the operating table to the hospital bed, it is necessary to carry out two manual handling of the patient, and the force is not easy to coordinate. Causes secondary injuries and suffering to critically ill patients after surgery. Summary of the invention

In order to make full use of the highly space-transportable transporter, the patient does not need to move the position during the transport. The present invention has four legs that are columnar, and can open the front legs and a hanger that can be raised and lowered up and down. The hanger has two rotating rods that can be rotated in opposite directions. Driven by two worm turbine reducers, the two rotating rods roll the sheets under the patient's body into a stretcher. In this way, the patient is on the stretcher without moving his body. Driven by two lifting worm turbine reducers, tighten the wire rope, lift the hanger, transport it to the ward, open the front legs, enter the bed from the longitudinal direction, lower the hanger, loosen the rotating rod, and bring the patient and bed sheets Putting them together on the bed

The technical solution adopted by the utility model to solve the problem is as follows: There are four legs in the shape of a column, the upper part of the four column-shaped legs is connected with two longitudinal beams, and the front ends of the two longitudinal beams each have a wheel cover, a wheel cover Each of the four wire rope reels is connected to the two worm turbine reducers through the drive shaft, and the four wire ropes are driven to move up and down under the driving of the two worm turbine reducers; The lower ends of the four steel ropes on the wire rope reel are respectively fixed on the front and rear beams of the hanger, which can drive the hanger up and down, so that the hanger can be placed above the operating table or lowered to the hospital bed. There are two rotating rods on the hanger, and each rotating rod has a slot, each slot There is a pressing rod in the middle, and both ends of the rotating rod have a clamp. The front end of the rotating rod is connected with the front cross rod, and the rear end of the rotating rod is connected with a worm turbine reducer, and the two worm turbines are reduced. The machine is fixed on the rear cross member, and the input shafts of the two worm turbines are connected by a transmission shaft. One of the worm turbine reducers has a hand crank on the input shaft, and the other worm turbine reducer is reversed. Each of the two longitudinal members is fixed on a vertical shaft, and each of the vertical shafts is sleeved with a vertical sleeve connected to the front legs. At the upper ends of the two vertical shafts, a positioning gear is fixed by a key, adjacent to the two front legs. A tooth positioning block that engages with the positioning gear is mounted on the upper end, and each of the two tooth positioning sleeves has a spring, and the rear ends of the two tooth positioning blocks are connected to the handle through the pull rod.

When using, cross the car on the operating table, lower the hanger and take off the pressure bar. Place the two sides of the sheets on the operating table on the rotating rod, press the two sides of the sheet into the groove with the pressure bar, turn the handle, two The rotating rods rotate in opposite directions, and the sheets are wound up to form a stretcher. In this way, the patient lying on the bed sheet goes to the stretcher without moving the body, shakes the lifting handle, raises the hanger, pushes the car to the ward, and the upper ends of the two front legs are respectively connected to the two fixed to the longitudinal beam. On the upper vertical shaft, each vertical sleeve is sleeved with a vertical sleeve connected to the front leg, and the two front legs are centered on the vertical axis, and the opening angle is defined by two gears and a tooth positioning block, in the hospital bed. Open the two front legs at 90 degrees at one end and raise the hanger above the bed. At this time, the transfer vehicle can enter the hospital bed from the hospital bed, then lower the hanger to the hospital bed, and shake the handle of the rotating rod. , loosen the sheets that have been wound up, remove the pressure bar, remove the sheets from the rotating rod, and leave the patient and sheets on the bed. During the transshipment process, the patient did not move the position and was always in a relatively static state. This completes the static transfer of the patient using the three-dimensional space.

The utility model has the following effects: The three-dimensional static transshipment is realized when the patient does not need to move the body, thereby avoiding the possibility of causing secondary injury and suffering to the critically ill person due to manual handling, and improving the working efficiency of the medical staff.
