Abstract
The present invention allows on demand retrofit of a bed (2) with the sensing units (9) of a new monitoring system, which allows mechanical sensing of the presence of patients, movements of patients, breathing and heart rate.
Description
- The present invention relates to a sensor unit and a bed for a patient. Furthermore, the present invention relates to a method of modifying a patient's bed.
- Monitoring of patients during sleep is a standard tool in different situations, mostly in hospital settings. Depending on the diagnosis, different parameters are monitored. Parameters that are needed often are weight, heart rate, breathing rate and breathing abnormalities, as well as special movement patterns during sleep. It requires a significant technical effort and different techniques to measure these quantities.
- In patent application EP 05109419.1 (Philips ID 298116), a new technique of bedside monitoring has recently been described, including a monitoring system, the sensor units of which are integrated into a hospital bed. This new system allows mechanical sensing of the presence of patients, movements of patients, breathing and heart rate. However, in practical use, such a type of patient monitoring will only apply to a certain part of all patients. For monetary and workflow considerations, it would be much more attractive to equip the bed with the sensor units only if required.
- It is an object of the present invention to provide a technique, which allows a retrofit of the bed with the sensing units on demand.
- The object of the present invention is achieved by a sensor unit for measuring at least one force component acting in a first direction, comprising a number of mechanical fasteners, said fasteners being adapted for establishing a mechanical connection to a bed in a way that the sensor unit is in a clearly defined position relative to the bed, said fasteners being detachable in said first direction.
- This object is achieved according to the invention by a bed for a patient, comprising a system for manipulating the position of the patient in a first direction, and further comprising a number of mechanical fasteners, wherein said number of fasteners attach a number of sensor units to the bed in such a manner that each sensor unit is in a clearly defined position relative to the bed, said number of fasteners are adapted in such a way that each sensor unit is replaceable by another sensor unit, and said fasteners being detachable in the first direction, and said replacing being achievable using the manipulating system of the bed.
- This object is achieved according to the invention by a method of modifying a patient's bed, the bed comprising a system for manipulating the position of the patient in a first direction, and further comprising a number of mechanical fasteners, said fasteners being detachable in the first direction, said method comprising the steps of operating the manipulating system in such a manner that the patient moves from a first position to a second position, replacing a number of first sensor units, which are attached to the bed by means of the fasteners in such a manner that each sensor unit is in a clearly defined position relative to the bed, by second sensor units, and operating the manipulating system in such a manner that the patient moves from the second position to the first position.
- The present invention describes a design of a bed and a sensor unit. Furthermore, the present invention describes a method of handling said sensor unit with said bed.
- A bed according to the present invention is defined as a surface or any other device to rest on or to sit on etc., e.g. a conventional bed, a hospital bed, a couch, a conventional chair, a dentist's chair, a wheelchair, an (operating) table, etc. However, the present invention is preferably applicable in hospital settings. Accordingly, the bed is preferably a hospital bed.
- A working sensor unit according to the present invention is preferably a sensor unit as described in patent application EP 05109419.1 (Philips ID 298116), the disclosure of which is incorporated herein by reference.
- A core idea of the invention is to provide a technique which allows for a retrofit of the bed with the sensing units on demand. Thus, not every hospital bed has to comprise these integrated sensor units, but can be equipped with the sensor units when relevant. This significantly reduces the cost of hospital beds. The retrofit can be done easily by care personnel, no technician is required. This is achieved according to the invention by using detachable mechanical fasteners, which attach the sensor unit dummies or the working sensor units to the bed in such a manner that they are in a clearly defined position relative to the bed. The main advantage of the present invention is the easy replaceability of one type of sensor unit by another type. This is achieved by using the existing manipulating system of the bed. In other words, the manipulating system of the bed, which is already available, can be utilized for retrofitting. Furthermore, the present invention may as well be used for a simple replacing of working sensor units, e.g. in case of repair or maintenance. Because of the fact that the fasteners are detachable in the same direction into which the manipulating system is operating, which also corresponds to the direction in which a force to be measured by the sensor unit is acting, an easy retrofit is possible and at the same time a secure mechanical connection between the sensor unit and the bed can be guaranteed.
- These and other aspects of the invention will be further elaborated on the basis of the following embodiments, which are defined in the dependent claims.
- According to a preferred embodiment of the invention, the sensor unit dummies and the working sensor units comprise a number of spline shafts and the bed comprises a number of receptacles for said spline shafts or vice versa. In this manner a very simple and effective attaching system is provided. The use of spline shaft elements eliminates the risk of confusion during the replacement of the sensor units. To achieve easy handling during sensor unit exchange or retrofit, the spline shafts and receptacles run in the operating direction of the manipulating system. The retrofit can easily be performed by care personnel or even back staff. Where applicable other attaching elements can be used.
- According to another preferred embodiment of the invention, a number of fasteners comprise a quick opening device. The use of quick opening devices makes the replacing procedure even easier and ensures a fast retrofit during short periods of bed manipulations.
- Preferably, the bed comprises a base frame and a patient support, the patient support being connected to the base frame. Since the patient support in a hospital bed is usually connected to the base frame in an adjustable way (e.g. for providing height adjustment), integration of the sensor unit into the patient support requires a greater effort in terms of measuring and/or data processing, because the directions of the force components may vary depending on the variable position of the patient support. Thus, for unobtrusive monitoring of said parameters, integration into the base frame is preferred. Thus, according to yet another preferred embodiment of the invention, a number of fasteners are attached to or part of the base frame and the patient support, and a number of sensor unit dummies or a number of working sensor units are attached by means of the fasteners between the patient support and the base frame. This position allows for the measurement of forces of the patient support relative to the base frame of the bed. This will allow optimal characterization of patient movements and ensure optimal extraction of heart rate, breathing rate and weight, and it will also allow monitoring of these data over a period of time.
- According to another preferred embodiment of the invention, the manipulating system is adapted to lower the patient support into a displacement position, in which the sensor units can be partly detached from the bed and the replacement of the sensor units can be carried out, while the patient support is supported from below by a number of displacement rods. For the time of the retrofit said displacement rods serve as a replacement for the base frame of the bed. The use of displacement rods ensures safe positioning of the patient support during the replacement procedure.
- According to another preferred embodiment of the invention, a hydraulic manipulating system is provided for easy manipulation of the patient support, thus assuring an easy retrofit.
- The present invention allows for the first time an on demand retrofit of a bed with the sensing units of a new monitoring system, allowing mechanical sensing of the presence of patients, movements of patients, breathing and heart rate.
- These and other aspects of the invention will be described in detail hereinafter, by way of example, with reference to the following embodiments and the accompanying drawings; in which:
-
FIG. 1 shows a schematic illustration of a hospital bed with four sensor units, -
FIG. 2 shows an illustration of a working sensor unit with spline shafts and receptacles for said spline shafts, said receptacles being attached to the bed frame (not shown) and the patient support (not shown), and -
FIG. 3 shows a scheme of how to replace a sensor unit dummy by a working sensor unit or vice versa in seven steps. -
FIG. 1 shows a typicalmobile hospital bed 2. Thebed 2 comprises abase frame 3 and amoveable patient support 4. A patient's mattress (not shown) is positioned on the upside 5 of thepatient support 4. Thebase frame 3 comprises awheel frame 6 with fourwheels 7 and further comprises fourbedposts 8 extending upward from thewheel frame 6 to bear thepatient support 4. At the upper end of eachbedpost 8, identicalworking sensor units 9 are provided. In other words, thepatient support 4 is connected to the upper ends of the fourbedposts 8 via saidsensor units 9. Thebed 2 is configurable by means of hydraulics (not shown) in terms of height of the patient and positioning ofdifferent areas 11 of thepatient support 4 relative to each other. - The
sensor units 9 connect thebase frame 3 with thepatient support 4 in a movable manner. This means that, if a patient is located on the mattress, thepatient support 4 can be moved downward in the direction ofarrow 12. If the patient moves, thepatient support 4 is moveable sideward in an arbitrary lateral direction, for example in the direction ofarrow 13 or in the direction ofarrow 14. Those lateral movements are caused by “large scale” movements, e.g. when the patient turns, or by “small scale” movements, e.g. by the patient's beating heart or by the patient's breathing. - Each working
sensor unit 9 comprises two force sensor devices for sensing force components indifferent directions sensor unit 9 comprises a sender for sending measurement data to a data device using a wired or wireless data communication link. The specific position of thesensor units 9 allows for the measurement of forces of the mattress andpatient support 4 on which the patient is lying relative to thebase frame 3 of thebed 2. The weight of the patient as well as the patient's movements can be characterized and heart rate and breathing rate of the patient can be extracted by the data device, which for this purpose comprises a computer executing a dedicated computer program for extracting said information from the measuring data. - In
FIG. 2 , a singleworking sensor unit 9 is shown. In this embodiment, astrain gauge sensor 25, acting as first sensor device, is attached to thepatient support 4. For this purpose, aspline shaft 50 is attached to the upper connectingplate 27 of thesensor unit 9. The upper connectingplate 27 is mounted to thebottom side 29 of thepatient support 4 by means of three connectingmembers 30. - The
spline shaft 50 extends orthogonally from the upper connectingplate 27 of thesensor unit 9 towards thepatient support 4 in the direction ofarrow 12. Thepatient support 4 comprises a connectingplate 51 comprising a cylinder with areceptacle 52 for said spline shaft. Saidreceptacle 52 extends orthogonally from the connectingplate 51 of thepatient support 4 towards thesensor unit 9 in the same direction. Thereceptacle 52 comprises a plurality of axially extending recessed spaces 53 (grooves). Thespline shaft 50 is provided with a plurality ofribs 54 extending in the axial direction thereof, saidribs 54 being shaped to conform with said plurality of recessedspaces 53 of thereceptacle 52 for engaging thespline shaft 50 with thereceptacle 52. In this manner, anti-rotation of the shaft's axis is provided. As a result, thesensor unit 9 is in a clearly defined position relative to thepatient support 4. Thespline shaft 50 is retained in thereceptacle 52 by means of a quick opening device in form of a securingscrew 55. Said securingscrew 55 is adapted for securing thespline shaft 50 in thereceptacle 52 by entering abore 56 in thespline shaft 50 after thespline shaft 50 has taken up its end position. For this purpose, the securingscrew 55 is provided in anopening 57 in the receptacle's cylinder. The securingscrew 55 ensures a stable construction even during movements of thepatient support 4 and/or thebed 2. For reason of clarity, the cylinder inFIG. 2 is shown with parts of the cylinder's wall being omitted. - The
strain gauge sensor 25 is adapted to measure a force component in avertical direction 12 in order to provide the patient's weight. Thestrain gauge sensor 25 is mounted horizontally in aprotecting box 26 having a cylindrical shape. One end of thestrain gauge sensor 25 is linked with the free end of an upper T-shaped connectingplate 27 by means of a vertical intermediate piece (not shown). - The other end of the
strain gauge sensor 25 is linked with aslide 31 by means of a connecting member. Theslide 31 allows for relative movements of thebase frame 3 and thepatient support 4. Theslide 31 is mounted on arail element 33. Therail element 33 extends horizontally and perpendicular to thelongitudinal axis 34 of thestrain gauge sensor 25. Onefront end 35 of theslide 31 rests again apiezo sensor 36. Thepiezo sensor 36 acts as second sensor device and is rigidly attached to a mainly U-shaped lower connectingplate 37. The lower connectingplate 37 comprises anotherspline shaft 50, extending orthogonally from the lower connectingplate 37 towards thebase frame 3. The base frame again comprises a connectingplate 51, which comprises areceptacle 52 for saidspline shaft 50. The functionality offastener elements fastener elements sensor unit 9 takes a clearly defined position relative to thebase frame 3. - The
rail element 33 guiding theslide 31 is provided in between the two U-legs 39, 40 of the lower connectingplate 37 and thepiezo sensor 36 is mounted on the inside of thefirst U-leg 39. Thepiezo sensor 36 is adapted to measure a force component in a horizontal direction, e.g. indirection piezo sensor 36. Theslide 31 is connected with thepiezo sensor 36 via apre-stressed spiral spring 41. Thespiral spring 41, which exerts a certain defined tension force on thepiezo sensor 36, is mounted on the inside of the opposite second U-leg 40, and is connected with the otherfront end 42 of theslide 31. The initial tension of thespiral spring 41 can be adjusted by means of an adjustingscrew 43 on the outside of thesecond U-leg 40. Instead of aspiral spring 41, other types of resilient elements may be used. - The functionality of the
mechanical fasteners sensor unit 9. A sensor unit dummy (not shown) according to the present invention exhibits the same attaching functionality. However, the sensor unit dummy is a mechanical component that replaces the workingsensor unit 9, but is not carryingsensors spline shafts 50. When patient monitoring is required, each dummy sensor unit can be replaced by a workingsensor unit 9, as explained below. - With reference to
FIG. 3 , a replacing procedure is explained. In order to replace sensor unit dummies 9′ with workingsensor units 9, in afirst step 101, the securing screws 55 of thespline shafts 50 between the sensor unit dummies 9′ and thepatient support 4 are opened. In thenext step 102,displacement rods 60 are made available. Saiddisplacement rods 60 are preferably part of thebase frame 3 of thebed 2 and can be provided on demand by means of joints. Thebed 2 comprises a hydraulic manipulating system 61 (only illustrated schematically inFIG. 1 ). By means of said manipulating system, thepatient support 4 is lowered (direction 12) into a displacement position instep 103. In this position, thepatient support 4 is supported from below by a number ofdisplacement rods 60, while thebedposts 8 are in a position that is so low that the sensor unit dummies 9′ do not contact thepatient support 4. The sensor unit dummies 9′ can be detached from thebed 2,step 104, and the replacement can be carried out,step 105. Instep 106, thebase frame 4, now equipped with workingsensor units 9, is lifted up again and the securing screws 55 can be fastened. Finally, thedisplacement rods 60 are folded instep 107. - It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. It will furthermore be evident that the word “comprising” does not exclude other elements or steps, that the words “a” or “an” do not exclude a plurality, and that a single element, such as a computer system or another unit, may fulfil the functions of several means recited in the claims. Any reference signs in the claims shall not be construed as limiting the claim concerned.
