Description

Multifunctional universal bed for radiotherapy department

Technical Field

The invention relates to medical equipment of a radiation therapy department, in particular to a multifunctional universal bed of the radiation therapy department.

Background

The radiotherapy department is mainly used for treating various cancers and neoplastic diseases, when in treatment, a patient needs to be transferred into a treatment room from a ward, in the process, medical workers often need to lift the patient to a hand-push bed firstly, then push the hand-push bed into the treatment room, and then lift the patient to a special bed of radiotherapy equipment, so that the patient is repeatedly lifted, great pain is often brought to the patient, especially for the cancer patient, the canceration of the patient causes abnormal pain of a lesion part, the pain degree of the body posture adjustment is inevitably increased, unnecessary pain is brought to the patient, in addition, the physical consumption of the medical workers is large when the patient is lifted, the labor intensity of the medical workers is increased, high requirements and limitations are brought to the physical quality of the medical workers, and the timely transfer is not facilitated.

Because the height, position, angle and the like of the bed body need to be changed continuously according to the lesion part of a patient in the radiation treatment process, a special bed carried by the radiation treatment equipment is higher in integration degree with the equipment and is provided with various action control systems, and the special bed cannot be used with a common hospital bed and a hand-push bed.

Disclosure of Invention

Aiming at the defects, the invention provides a multifunctional universal bed for a radiotherapy department, aiming at solving the problem that a patient cannot be conveniently transferred between the conventional radiotherapy bed and other beds, so that the patient obtains light and comfortable sickbed transfer experience, unnecessary physical consumption of medical personnel is reduced, the transfer efficiency of the patient is improved, and the patient can obtain timely radiotherapy.

In order to solve the problems, the technical scheme adopted by the invention is as follows:

the bed board can be lifted through a support frame, the bed board can slide and translate on the support frame, the head end and the tail end of the bed board are respectively provided with an outward-protruding sliding rail, the bed frame is provided with a sliding groove corresponding to the sliding rail, and the bed board can slide and translate along the width direction of the bed board under the limiting action of the sliding rail and the sliding groove; the upper and lower width of the sliding chute is larger than that of the sliding rail, so that the bed board has a lifting space in the upper and lower directions; the difference between the upper width and the lower width of the sliding groove and the sliding rail is not smaller than the thickness of the bed plate, so that the high-position space and the low-position space where the bed plate is located do not coincide when the bed plate is at a higher position and a lower position, interference and collision are avoided when the bed plate is exchanged, and smooth implementation of the bed plate exchange is ensured.

Furthermore, the bed frame is provided with a wedge-shaped lock pin which corresponds to the sliding groove and elastically slides along the length direction of the bed frame, the wedge-shaped end of the lock pin is arranged in the sliding groove, the bed frame is provided with an unlocking mechanism which corresponds to the lock pin, and the lock pin is used for locking the bed plate in a one-way mode to prevent the bed plate from falling accidentally at a higher position or rising accidentally at a lower position.

Furthermore, the width of the lock pin is not larger than the length of the sliding groove, so that the lock pin can be used for supporting and guiding the bed plate, and the bed plate is prevented from being suspended or turned on one side during exchange.

Furthermore, the bed frame is provided with a reversing synchronizer in transmission connection with the bed boards, so that when the bed boards exist at the higher position and the lower position at the same time, the two bed boards keep synchronous reverse sliding, the two bed boards do not need to be pushed, the simultaneous movement of the two bed boards can be realized by controlling the sliding of any bed board, the operation steps and the number of operators are reduced, and the operation efficiency is increased.

Compared with the prior art, the invention has the following technical effects: according to the invention, the existing bed body is locally improved, so that the bed boards can be rapidly exchanged among the medical beds with different purposes, thereby realizing the transfer of patients, avoiding the need of carrying the patients, reducing the pain of the patients and relieving the labor of medical staff; by means of lifting of the bed plates, positioning of the lock pins and the reversing synchronizer, when the bed plates are exchanged, the effect of synchronous reverse movement of the two bed plates can be achieved by operating any one bed plate, the operation and the control are more convenient and faster, and the positioning after the bed plates are exchanged is more accurate; when the bed board is exchanged, the patient does not need to be matched and exert force, and the inclination, the rotation and the large-amplitude lifting do not exist in the exchanging process, so that the true non-inductive transfer is realized, and the posture and the body position of the patient are not influenced.

In addition, the patient is transferred by adopting the invention, and the patient always uses the same bed plate, mattress, bedding and the like, thereby effectively avoiding the cross infection risk caused by the fact that different patients share the special bed of the radiotherapy equipment in the prior art, reducing the consumption of medical resources such as disposable sterile mattress, disinfectant and the like, and reducing the generation rate of medical waste.
