Description

Technical Field

[0001] The utility model relates to the technical field of improved design of medical beds, in particular to a transfer bed used for emergency treatment. Background Art

[0002] The emergency department is one of the departments with the most acute and critically ill patients and the most diseases in the hospital. In the process of in-hospital diagnosis and treatment, it is often necessary to transfer acute and critically ill patients. Successful transfer has a positive significance for reducing the mortality rate of emergency critically ill patients. In-hospital transfer of critically ill patients in the emergency department is an important part of the daily work of the emergency department. In-hospital transfer of critically ill patients is to transfer from the emergency department to the ward or go out for examination through the transfer of rescue beds. Since many rescue beds are flat beds and the bed area is small, many items such as instruments, equipment, and transfer boxes can only be placed on the patient's bed. Not only does it occupy the patient's bed space, resulting in reduced patient comfort, but it also creates more or less hidden dangers. For example, the placement of oxygen cylinders is a headache for nurses. At present, the valve of the oxygen cylinder is relatively simple, and the knob for adjusting the oxygen flow is relatively simple. A light touch can cause a change in oxygen flow, resulting in a change in the patient's oxygen inhalation flow, and thus problems with patient safety. In addition, the oxygen cylinder is heavy, and during the movement of the bed, there may be problems with squeezing the patient's skin, which cannot be ignored.

[0003] Rescue equipment such as monitors, ventilators, and oxygen cylinders take up a lot of space. Some patients accidentally kicked the rescue equipment under the bed due to uncomfortable posture, causing damage to the components and economic losses. From the perspective of nurses, nurses need to observe the patient's vital signs and consciousness, infusion status, pipeline status, etc. during the patient transfer process. Complex and disordered instruments and items will distract the nurses' attention, and the placement of items during the rescue process will affect the rescue effect.

[0004] In the prior art, the patent with announcement number CN205698382U discloses a liftable rescue bed, including a rescue bed body, the rescue bed body includes a movable bed board, a bed frame and bed legs arranged in sequence from top to bottom; also includes a lifting mechanism, the lifting mechanism is arranged between the movable bed board and the bed frame; the lifting mechanism includes a support plate, a hydraulic rod and a rocker, the support plate is arranged on the lower surface of the movable bed board, the rocker passes through the front side end of the bed frame, and the hydraulic rod is arranged between the support plate and the rocker; the lifting mechanism is two, which are respectively arranged at the front and rear ends of the rescue bed body; the height of the bed legs is less than 60cm. The utility model is a liftable rescue bed, which can adapt to the height requirements of medical personnel of different heights for rescue, such as cardiopulmonary resuscitation, so that medical personnel can save time and effort during the rescue process, and further greatly improve the success rate of resuscitation.

[0005] In the above technical solution, by setting a lifting mechanism on the rescue bed, medical staff only need to operate the rocker to raise or lower the rescue bed to meet the needs of rescue personnel of different heights. Since the lifting mechanism is respectively provided at the front and rear ends of the rescue bed body, it is necessary to operate twice to adjust the height of the bed body, and the storage space between the bed body and the bottom bracket is limited, resulting in the inability to integrate sufficient rescue equipment.

[0006] In order to solve one of the above problems, the present application provides a transfer bed for rescue. Utility Model Content
