Definitions

• a technical solution describes weighing mechanism, particularly for weighing a patient on the patient support apparatus such as bed, cot, stretcher or like comprising a patient support deck coupled to an upper frame of the patient support apparatus, this upper frame fixed to the lower frame of the patient support apparatus by positioning cross or scissor lifting.
• the scissor lifting is fixed in relation to the lower frame of the patient support apparatus by means of double weighing brackets comprising scales able to determine weight of a patient lying on the patient support apparatus.
• the patient support apparatus comprises a chassis frame with Sifting mechanism.
• the upper side of lifting mechanism is attached to the patient support deck frame and inside the patient support deck there is located weighing system that weighs the patient support apparatus and the patient.
• the advantage is that only patient support apparatus with patient is weighed without bed accessories.
• Such systems are, however, very expensive with respect to price and production, and therefore not accessible for many hospital and nursery facilities, in addition, in case of failure of the weighing system it is necessary to dismantle the entire patient support deck.
• a second type of weighing system may be represented by an external pad with weighing sensors, which is not integrated in the patient support apparatus, and is located between the support surface and the patient support deck at seat section.
• Disadvantage of this weighing system is the fact that the patient needs to be seated which is impossible in case of bedridden patient.
• Another disadvantage is possible pad contamination by fluids of pad excreted by the subjected patient lying on the bed (e.g. urine or blood) that may leak into the weighing system and disable the system.
• this weighing system does not have to be accurate enough if the weight of the support surface, which is deducted from the observed weight, is entered improperly. Despite obvious advantage in mobility of the pad the purchase price of such pad is usually high.
• a third type of weighing system is represented by sensors located in the chassis of the patient support apparatus, it means that the weighing frame is the frame of the chassis and the patient is weighed including the patient support deck.
• the mechanism is simple in design, which is advantageous, on the other hand, this type of weighing system still provides many disadvantages.
• the main disadvantage is higher weight which changes with lifting the patient support apparatus and also weighing of accessories that are permanently fixed to the patient support apparatus.
• Another technical disadvantage is three-frame structure of the patient support apparatus.
• the patient support apparatus comprises the upper patient support deck frame, the bottom weighing frame and bottom chassis frame. This structure design is impractical for caregivers as the patient support apparatus is heavy, difficult to operate and manipulate with and caregivers need to exert higher power to move the patient support apparatus.
• the existing patient support apparatuses with weighing systems comprise four load cells (i.e. tensometer or strain gauge) located in the weighing frame, when In principle, only three load cells may be used. To reach the highest accuracy the load cells are located in the weighing frame to frame edges as much as possible to have the biggest possible measured base. Another factor influencing weigh accuracy is a principle of locating the individual load cells.
• the above described location of load cells is primary defined and convenient for patient support apparatuses with scissor lifting and without possibility to tilt the patient support deck into Trendelenburg position, which means that the patient support deck may be positioned only from the lowest position to the highest position. Summary of the Invention

• Majority of patient support apparatuses with scissor lifting and possibility to tilt the patient support deck have usually no weighing system at ail as it is challenging in design and financial aspect as well.
• Majority of beds with scales have weighing system that is located in the double chassis frame. Weighing system in patient support apparatuses with scissor lifting cannot have scales located under the patient support deck due to improperly distributed forces. If the weighing system does not run with properly distributed forces, it cannot weigh right and the measured weight id stated false.
• the preferred embodiment of the bracket weighing system presented herein comprises a iower frame of the chassis equipped with wheels on the bottom side and fixed in relation to an upper frame of the patient support deck by scissor lifting.
• the iower frame of the chassis comprises two types of weighing brackets so that it could be possibie to weigh the patient also in case when the patient support apparatus Is positioned to different positions (e.g. Trendeienburg position or anti-Trendelenburg position).
