A hospital bed and medical equipment

Abstract

The invention provides a sickbed and medical equipment. The sickbed comprises a bed board, a drive mechanism, a support mechanism and a locking mechanism, wherein the support mechanism is used for supporting the bed board, the drive mechanism is used for driving the bed board to move, and the locking mechanism is used for locking the support mechanism at a specific position. The sickbed has the advantages that that sickbed height and stability can be kept, particularly the problem of sickbed height decreasing or sickbed position instability caused by the fact liquid in hydraulic driving equipment leaks is solved, the problems of extra mechanical resistance and efficiency decreasing caused when a sealing part or sealing mechanism is adopted for leaking sealing are avoided, and thus, the problems of sharp increasing of manufacturing cost and processing difficulty caused by adoption of the sealing part are avoided.

Description

technical field [0001] The invention relates to medical equipment, especially a magnetic resonance imaging system, and in particular to a sick bed for medical equipment. Background technique [0002] For medical examination equipment such as magnetic resonance imaging (MRI, Magnetic Resonance Imaging) equipment, computerized tomography (CT, Computed Tomography) equipment, etc., the patient examination table (PTAB, Patient Table) is its core component. [0003] figure 1 is a schematic diagram of a hospital bed according to the prior art. Such as figure 1 As shown, the basic function of the hospital bed (also called examination bed, examination table, etc.) is to carry or support (vertical direction V) the patient / patient, and move the patient / patient (horizontal direction H) to a predetermined examination position, where It includes a bed board 101, a driving mechanism 102 and a supporting mechanism 103. The bed board 101 can move down to a lower height so that the patien...

AI Technical Summary

Problems solved by technology

like figure 2 As shown, hydraulically driven equipment also has its own unavoidable disadvantages: hydraulically driven equipment uses the pressure generated by liquid (such as oil) to work, so the liquid will leak from the high-pressure area to the low-pressure area through the piston or valve, and the sealing parts or agencies can only mitigate but not avoid such situations

Moreover, although sealing components or mechanisms can be used to alleviate the above situation, the sealing components or mechanisms will also bring additional mechanical resistance and reduce efficiency when sealing the leakage. In addition, the sealing components will also greatly increase the manufacturing cost and processing difficulty.
