Description

A carriage car for a patient}

The present invention relates to a patient carriage, and more particularly to the four wheels (casters) installed at the bottom of the leg of the patient carriage can be easily fixed simultaneously as a lever (i.e. actuated brakes mounted on the wheels or It can be easily operated as a lever when it is released.) The bed can also be electrically operated up and down, right and left, and incline to operate freely, so that the power according to the bed operation can be supplied by the charger. By doing so, the wires for supplying power when transporting the patient transport car are not exposed to the outside, the appearance is clean, and the patient transport and transport in any place is made easy and very convenient and safe.

As is well known, patient transport cars are mainly used in hospitals, public health centers, fire departments, and emergency services, and are used to transport emergency patients or critically ill patients.

However, as described above, the conventional patient carriage used for transporting emergency patients or critical patients has the following problems.

That is, since four legs are usually installed at the lower part of the patient carriage, and casters each having a brake device are installed at the bottom of the patient carriage, the four casters are used to stop for a while during the rapid transportation and transportation of emergency patients. Only when the individual brake devices are stepped on, the carriage cart can be fixed stably, but it is very cumbersome and time-consuming to fix all the brakes mounted on the four casters. It is common for people to step on and fix only one or two casters of the four casters closest to their position. However, if only one or two brakes are operated as above (because each of the four casters are rotated 360 °), even if a little pushing or impact is applied at the time of stopping, the carriage is sometimes moved to the rotation or the unexpected part. Dangerous situations, such as shocking patients, often occurred.

In addition, the general patient carriage is inclined only by the front and rear of the bed, and the height of the bed, the left and right inclination and the bed itself are not transferred at all, so that the intensive care unit or the emergency patient is in the intensive care unit, the operating room or the emergency room. It is very inconvenient and difficult because it is necessary to lift and carry the patient directly when carrying it on another bed and carry it on the back. .

In addition, in the case of a general hospital, a university hospital, or a private hospital equipped with an operating room, a patient carrier carrying a surgical patient is transported from the waiting room to the operating room recovery room to perform surgery and recovery. Because it is difficult to move the patient on the operating room bed because the patient is transported to the operating room as it is very unsanitary, it also acted as a significant factor to slow the occurrence and recovery of side effects of the surgical site.

Therefore, the present invention has been invented in view of the above-mentioned problems with the conventional patient carriage, and in particular, the brake operating rings are respectively installed on the upper side of the four wheels installed in the patient carriage, and they are connected between the shaft and the connection and the lever and the installation. As a lever, allowing the four wheels to be locked at the same time (in which direction the wheels are headed), making it very quick and easy to brake or release,

In addition, the bed can be freely moved up and down, left and right, and tilt adjustment by the transmission structure consisting of the reduction motor, the timing belt and the pulley, and the screw, so that the transportation of the intensive care and emergency patients or the aseptic treatment of the operating room Its purpose is to ensure very hygienic and safe use by allowing safe transport with little impact on the patient when transporting it to a bed or other bed in an intensive care unit.
