ABSTRACT OF THE DISCLOSURE
A scale for weighing a patient in his horizontal position. The scale has a support frame including an up-right post and means for moving the frame over the ground and against a bed of the patient so that the post is closely adjacent a side of the bed. A weighing mechanism is carried by the frame and includes a flat weigh-board that can be positioned so that it extends horizontally away from the post at a point sufficiently elevated to place the weigh-board over the bed when the post is closely adjacent the bed side. Guard rails rigidly connect with the frame and are disposed beneath the board. The rails prevent the bed side from contacting any part of the weighing mechanism when the post is closely adjacent the bed side and the board is positioned above the bed.

Description
~74347 This invention relates to a scale for weighing a patient.
This application is divided from Canadian appli-cation 265,836 filed November 16, 1976.
In treating hospital patients the body weight and its fluctuations are often of great importance, particularly in cases of actual or impending electrolyte and water im-balance. This determination supplements laboratory data, and makes its interpretation easier, more accurate, more relevant and more meaningful. It provides the clincial observer with objective information which may prove vital for proper and successful treatment of the patient.
In some case, it is necessary that bedridden patients remain in their lying position. To weight such patients the scale must be constructed so that the patient can be transferred from the bed onto the scale and weighed while he remains inclined. Such scales generally provide a support structure usually freely movable over the ground by mounting the structure on casters and a weighing mechanism including a weigh-board carried for supporting the patient in his inclined position during the weighing operation. The weigh-board is sufficiently elevated above ground so that is can be moved over the patient's bed. The support structure includes a base disposed below the weigh-board which is moved beneath the bed while the weigh-board is positioned over the bed. To facilitate the storage of the scale while not in use the weigh-board is normally attached to the weighing mechanism so that it can be placed into an upright storage position. A scale of this type is disclosed in U.S.
Patent 3,032,131 issued to Schmerl, May 1, 1962.
~074347 There are other prior art scales for weighing patients in their horizontal position which structurally differ from the one disclosed in the referenced patent.
However, all scales have the general characteristic of 5 providing a horizontal weigh-board, a movable support frame over the bed for receiving the patient while providing a sturdy and stable support for the weigh-board.
Prior art scales for weighing patients in their horizontal position generally enable accurate measurements and they are relatively convenient for transferring the patient from the bed to the scale and back. However, they have a number of practical deficiencies which can render ` such scales cumbersome to handle and which may impair their accuracy unless the attendant carefully isolates the scale, and particularly the components of the weighing mechanism, from coming into contact with objects such as the side of the patient's bed, for example. If such contact does occur the measured weight is of course, inaccurate. This is particularly serious because such inaccuracies cannot be detected after the measurement has been taken and the scales provide no means of warning the attendant that the weight he measures is inaccurate because the weighing mechanism is in contact with a foreign object, e.g., the bed.
Accordingly, the prior art scales for weighing bedridden patients in their horizontal position, while they were adequate when properly operated, had several features which could compromise their accuracy.
~ he present invention is broadly directed to improving prior art scales for weighing bedridden patients in their horizontal position to enhance the accuracy, safety and convenience of such scales.
In a first aspect the present invention is a scale for weighing a patient in his horizontal position compris-ing: a support frame including an upright post and means for moving the frame over the ground and against a bed of the patient so that the post is closely adjacent a side of the bed; a weighing mechanism carried by the frame including a flat weigh-board and means positioning the weigh-board so that it extends horizontally away from the post at a point sufficiently elevated to place the weigh-board over the bed when the post is closely adjacent the bed side; and guard means rigidly connected with the frame, disposed beneath the board and preventing the bed side from contacting any part of the weighing mechanism when the post is closely adjacent the bed side and the board is positioned above the bed.
In a further aspect the invention is a scale for weighing a patient in the horizontal position comprising: a supporting frame including a horizontal base having a for-ward end and an aft end and lateral sides, an upright post connected to the base and positioned adjacent the aft end and means permitting the frame to be moved about a support-ing surface; a weighing mechanism including a carriage vertically movable along the post and facing towards the forward end of the base, a horizontally disposed weigh-board connected with the carriage at a point spaced above the base and on the side of the post facing the forward end of the base, and means for determining the weight placed on the weigh-board; whereby a generally horizontal object spaced from the surface can enter the space between the weigh-board and the base; guard means for shielding the carriage and ~074347 parts connected therewith from being contacted by said object. The guard means comprising a pair of upright bars having their lower ends immovably secured to the frame, and a brace connecting the upper ends of the bars with the frame for stiffening the upper ends, the upright bars being positioned forward of the carriage so that the bars inter-cept the object before the object can contact the carriage and influence the measured weight.
The provision of the guardrails forward of the vertically movable carriage shields the carriage and there-with the otherwise accessible components of the weighing mechanism from contact with the side of the bed when the scale is wheeled against the patient's bed. The attendant need not pay attention to clear the weighing mechanism from contact with the bed side and need not be concerned with the possibility that during the weighing operation the scale might move towards the bed so that contact between the bed and the weighing mechanism would interfere with the accurate weighing process. Instead, the present invention positively prevents such contact and resulting inaccuracies in the measured weight. Thus, the attendant can concentrate on the weighing process without having to observe the patient's safety and comfort, and adjust the relative position of the bed or the scale.
An embodiment of the invention is illustrated in the accompanying drawings in which:
Figure 1 is a side elevational view of a scale constructed in accordance with the present invention;
Figure 2 is a front elevational view of the scale shown in Figure l;
1~74347 Figure 3 is a fragmentary, enlarged cross-sectional view and is taken on line 3-3 of Figure 1; and Figure 4 is an enlarged, fragmentary side ele-vational view and is taken on line 4-4 of Figure 2.
Referring to the drawings, a scale 2 constructed in accordance with the present invention for weighing bedridden patients in a horizontal inclination generally comprises a supporting frame 4 including a base 24 which mounts casters 6 for freely rolling the scale about a hori-zontal support surface such as a hospital floor ~. The frame has a forward end 10 and an aft end 12 and includes a pair of spaced-apart upright posts 14 which have a generally U-shaped cross-section defined by relatively short side flanges 16, 18. The posts project upwardly from the base adjacent the aft end thereof.
~ounted to base 24 is a weighing mechanism 20 which includes a horizontal weighing platform 22 disposed above the base 24. The weighing mechanism further includes spaced-apart carriages 26 which are vertically movable along front face 28 of posts 14 via a suitable carriage lifting mechanism (not shown in the drawing but illustrated in the above-referenced U.S. Patent) and a pair of forwardly extending, spaced-apart horizontal arms 30 mounted to the carriages and protruding from adjacent the upright posts towards the forward end 10 of frame 4. The carriages are interconnected by a shield 27.
A weigh-board 32 is secured to one of the arms, say the lefthand arm (as seen in ~igure 2), with hinges 34 for pivotal movement of the board about a generally hori-zontal pivot axis (which is parallel to the arms) between a ~74347 horizontal operative position and a vertical storage posi-tion. The latter position is shown in phantom lines in Figure 1 and 2. The weighing mechanism further includes the conventional weighing beam, poises, sight indicators, etc.
mounted to an upright support 36 and collectively identified in the drawings with reference numeral 38.
The scale is used as follows. During non-use the weigh-board 32 remains in its vertical storage position to reduce the required storage space and prevent the board from interfering with normal hospital traffic. ~or use the attendant pivots the board into its horizontal position and raises it sufficiently (by raising carriages 26 along upright posts 14) so that the weigh-board and the supporting horizontal arms 30 are slightly above the upper surface of a bed 40. The scale is now pushed forward to place the weigh-board over the bed until a side 42 of the bed is closely adjacent carriages 26. The patient is then transferred from the hed onto the weigh-board by rolling and/or sliding him onto the weigh-board. Thereafter the weighing operation is performed and upon its completion the patient is transferred from the weigh-board to the bed by reversing the above-described steps.
Since carriages 26 and their interconnecting shield 27 form part of the weighing mechanism any contact between an outside object, such as bed 40, and the carriages would render the weight measurement inaccurate. It is, therefore, necessary to maintain a positive spacing between the carriages and bedside 42. For that purpose the present invention positions an upright guardrail 44 immediately forward of the carriage. The lower end of the guardrail is rigidly secured to frame 4. To enable the positioning of the scale as closely adjacent the bed as possible it is preferred that the guardrail be constructed of a bar having a rectangular cross-section with the thickness of the bar extending parallel to horizontal weigh-board supporting arms 30. In this manner the bar takes up minimum space. To prevent such a guardrail from being deflected when the scale is pushed against the bedside, for example, an inclined brace 46 is provided for each rail. The brace has a first end connected to the upper end of the guardrail 44 while the other, lower end is connected, e.g., bolted, to the aft end 12 of support frame 4. In this manner, both guardrails providing a rigid protection for the weighing mechanism in general and carriages 26 in particular, so that even if the scale is pushed against the bedside 42 the measurement remains accurate because no physical contact between the bed and the weighing mechanism is possible. For particular applications it might be desirable to include a horizontal connecting plate 48 (shown in phantom lines in Figure 2 only) between the upper ends of guardrails 44.
To assure that the weigh-board remains in its horizontal position during the weighing operation a latch 50 is mounted to a side 52 of the weigh-board facing horizontal arms 30. The horizontal arm 30 opposite from the arm con-nected to hinges 34 includes a catch such as a metal loop 54 positioned to engage a hook 56 of the latch. To return the weigh-board to its vertical storage position the attendant retracts a release lever 58 of hook 56 to disengage the hook from the catch.
To prevent the weigh-board from being pivoted past '1074347 its vertical position a stop 60 is secured to the carriage 26 which is adjacent the board when the latter is in its storage position. The stop may be mounted to a suitable support bracket (not shown in the drawings) and it is preferably constructed of a resilient material to prevent it from scratching or otherwise damaging the board.
A locking mechanism 62 for releasably retaining the board in its vertical storage position is provided. The locking mechanism comprises a horizonally disposed tube 64 disposed between and connected to posts 14. An elongate bar or lever 66 is rotatable in the tube and has ends projecting therefrom. A protrusion 68 extends perpendicular to the lever and is positioned to engage side 52 of weigh-board 32 as is best seen in Figure 4. The opposite end of the lever is fitted with a perpendicularly protruding handle 70 which enables pivotal movement of the lever and therewith of protrusion 68 between a first, board engaging and locking position and a second, board releasing position (shown in phantom lines in Figure 4). To facilitate the ease with which the locking mechanism 62 is operated, a second handle (not shown in the drawings) may be mounted to the end of lever 66 from which protrusion 68 extends. In this manner, the attendant can lock or release the weigh-board from either side of the scale.
