Description

Title of the invention: Posture assistance device equipped with contact or contactless electronic identification means

[0001] The invention relates to technical aid devices for posture, and more particularly to pressure ulcer prevention equipment called positioning cushions.

[0002] The term "bedsores" here refers to skin ulcerations or necrosis resulting from prolonged compression of soft tissues against an underlying bony prominence on a weight-bearing surface of the body. Bedsores are skin lesions of ischemic origin.

[0003] Risk factors for pressure ulcers are conventionally classified into extrinsic or mechanical factors (in particular pressure, friction, shear), and intrinsic or clinical factors (in particular immobility, nutrition, incontinence, skin condition, decreased blood flow, neuropathy, age, history of pressure ulcers).

[0004] Numerous risk assessment scales have been proposed (Norton scale, Braden scale, Waterloo scale, Cubbin and Jackson scale, the French-language scales of Colin and Lemoine, the Peupliers-Gonesse scale, the Angers scale, the Geneva scale). Despite their limitations, pressure ulcer risk assessment scales are conventionally taken into account when deciding on the implementation and financial coverage of technical means for pressure ulcer prevention. For example, in France, to determine the threshold for health insurance coverage of the cost of mattresses, mattress overlays, and cushions used to prevent pressure ulcers, the Norton scale is used, with a coverage criterion being a score of 14 or less on the Norton scale or a patient with an equivalent risk, assessed by another validated scale.

[0005] The appearance of a pressure ulcer often leads to a significant decrease in quality and comfort of life, as well as physical discomfort and suffering, particularly during care.

[0006] The impact of pressure ulcers in terms of public health is very high. An evaluation of the costs of prevention and treatment of pressure ulcers is presented by Démarré et al, The cost of prevention and treatment of pressure ulcers: a systematic review, International journal of nursing studies (2015), pp. 1754-1774.

[0007] Bedsores are seen as adverse events during hospitalization, which can lead to legal action, which is common in the United States.

[0008] The technical means implemented for the prevention of pressure ulcers are typically gel cushions, memory foam cushions, single-density foam waffle-shaped mattresses, vis- foam mattress overlays coelastic memory foam, air mattress toppers (constant pressure, dynamic, mixed or air-losing), mattresses including inserts in areas at risk of pressure sores (water insert).

[0009] The areas at risk and preferred locations for pressure ulcers are the sacrum and the heels, particularly in patients lying on their backs. Other locations are possible, such as the ischial tuberosities, the trochanter (in people lying on their side), or the occiput; all pressure points can develop a pressure ulcer, for example, the elbows or knees.

[0010] The position in which the patient is most often found has an impact on the most likely location of a pressure ulcer. Thus, for example, pressure ulcers on the occiput, sacrum, heels, thoracic spine, shoulder blades and elbows are associated with a supine position.

[0011] The European Pressure Ulcer Advisory Panel (EPUAP) has developed recommendations for the prevention of pressure ulcers, in conjunction with the American National Pressure Ulcer Advisory Panel (NPUAP). Regular mobilization, for example every two hours, is considered one of the effective techniques for reducing the risk of pressure ulcers, particularly when positioning cushions are used.

[0012] In bed, to alternate with the supine position, patients are often moved into a 30° oblique lateral decubitus position (to the right or left) relative to the bed plane, with positioning cushions placed under the head, between the legs, and under the buttocks. In the oblique lateral decubitus position, pressure on the trochanter and sacrum is thus eliminated.

[0013] Positioning cushions have shapes adapted to different types of pressure ulcers. For example, cushions are used when a person is moved to a lateral position to reduce the risk of developing a trochanteric pressure ulcer. Other cushions, in various shapes, are used to offload pressure on the malleoli, femoral condyles, and knees, or to prevent sacral, ischial, and heel pressure ulcers.

[0014] Positioning cushions can thus be cylindrical in shape (for use for example under the heels and under the ankles), or in the shape of a half-ring (knee abduction cushion), a half-moon for bracing the back of a patient in a semi-Fowler position, or in the shape of an S for mobilization in oblique lateral decubitus.

[0015] Reference can be made, for example, to documents DE19927404, WO2012162751, FR2896406. Reference can also be made to the document Angel, How to prevent and treat pressure ulcers in a bedridden person in 2017, University of Caen, 2018.

[0016] Positioning cushions, when used correctly, can partially or completely relieve pressure on an area at risk of pressure sores, by reducing strongly the shear forces and the friction due to sliding.

[0017] Positioning cushions, when used correctly, can help correct vicious postural attitudes, which are frequently involved in the process of pressure ulcer formation.

[0018] Positioning cushions used at home are reimbursed in France, pursuant to Article L615-1 of the Social Security Code, these products being subject to medical prescription and appearing on a list (LPP) established by decree after consultation with the High Authority for Health HAS (R165-1 et seq. Social Security Code).

[0019] Positioning cushions are prescribed in France by doctors, and in some cases by occupational therapists (decree of June 12, 2023), with two types of prescription: standard positioning cushion alone, or modular positioning cushion combining a base and one to four pads.

[0020] Although they are eligible for pressure ulcer prevention, it is estimated that only 25% of at-risk patients have access to positioning cushions. It is estimated that 70% of nursing homes are not equipped with positioning cushions.

[0021] This situation is a priori all the more paradoxical given that a wide variety of positioning cushions are marketed by various manufacturers.

[0022] The applicant has endeavored to elucidate this problem by questioning the various stakeholders, in particular caregivers (doctors, nurses, nursing assistants) working in multidisciplinary teams.

[0023] Among the reactions and justifications received, it appeared that the multiplicity of The different shapes and names of positioning cushions available on the market were a barrier to their use. Healthcare professionals experienced some confusion when prescribing and using existing positioning cushions, and feared they were not choosing the right cushion for their patients.

[0024] Caregivers also express concerns about the risks of misuse of cushions.

[0025] When used incorrectly, positioning cushions can restrict a patient's spontaneous movements and mobility, with adverse consequences for their general condition. Inappropriate positioning can lead to muscle contractures, joint stiffness, respiratory problems, and circulatory problems.

[0026] Healthcare professionals also expressed concerns regarding cleaning and disinfection procedures. Commercially available cushions contain various filling materials, including microbeads or microfibers, with these fillings contained in covers made of different materials.

[0027] The applicant has sought to address these problems, in order to make the use of simpler and easier positioning cushions, more intuitive and more natural.

[0028] For these purposes, it is proposed, according to a first aspect, a technical aid device for posture, in particular preferably a positioning cushion for the prevention of pressure sores, the device being provided with a means of electronic identification with contact and / or without contact.

[0029] In this description, the expression "and / or" refers to the possibility of an alternative (or) as well as the possibility of a combination (and).

[0030] The term “contact electronic identification means” refers here in particular to electronic chips.

[0031] Advantageously, the electronic chip is visible, for example placed on a card attached to the positioning cushion. The card is, for example, placed in a transparent or translucent card holder, the card holder being attached, in particular welded, glued or sewn, to the cover of the positioning cushion.

[0032] The user can then remove the smart card and insert it into a card reader, advantageously connected to a mobile communication terminal, such as a smartphone. The user will then advantageously have access to information concerning the positioning cushion, this information being stored in the mobile communication terminal, or being accessible via the mobile communication terminal, this information being stored on a dedicated server, or available in the cloud.

[0033] By "contactless electronic identification means", we mean herein in particular radio frequency link means, such as RFID (radio-frequency identification) radio frequency tags and NFC (near-field communication) tags.

[0034] The RFID tag includes a chip and an antenna enabling communication between the chip and an RFID reader. The information collected by the reader is processed via software and its database.

[0035] Advantageously, the RFID tag is passive and operates without a battery. Placed in the electromagnetic field of the reader, the chip is powered by electromagnetic coupling, and then data can be exchanged between the chip and the reader.

[0036] Advantageously, the communication link between the tag and the reader is at high frequency (13.56 MHz), or at very high frequency (800 MHz), allowing a high detection distance, equal to or greater than 1 meter.

[0037] In some embodiments, the RFID tags or NFC tags are visible to the user, and are for example placed in housings fixed on the cushion, for example a pouch or a transparent case fixed on the cover of the positioning cushion.

[0038] In other embodiments, RFID tags or NFC tags are These tags are placed inside the cushion to protect them from impacts, liquids, and cleaning or disinfecting products. Advantageously, information is displayed on the cushions, in the form of text and / or drawings, informing the user of the presence and operation of these RFID tags or NFC tags.

[0039] RFID or NFC technologies offer several advantages.

[0040] In particular, these techniques facilitate inventory management, as the user can scan the positioning cushions around them using a handheld RFID scanner. Several dozen tags can be read in a few seconds.

[0041] RFID or NFC technologies facilitate traceability. In the event of a problem with a cushion, for example a sanitary issue requiring cleaning or disinfection, healthcare staff can identify the affected batch of cushions. In the event of a nosocomial infection or contagious disease, it is thus possible to identify all the positioning cushions requiring treatment.

[0042] RFID or NFC technologies also make it possible to verify the origin of positioning cushions and detect counterfeits. RFID tags can contain a large amount of manufacturing data.

[0043] The term “contactless electronic identification means” also refers to optical vision means, such as linear barcodes or bidirectional (or two-dimensional) barcodes, including QR codes (for Quick Response), Aztec codes, DataMatrix or PDF417 codes.

[0044] The PDF417 code (for Portable Data File) is a stacked linear barcode of variable length, using stacked rows of bars to encode data.

[0045] The DataMatrix code is described in the ISO / IEC 16022 standard. The DataMatrix code has the particular advantage of including an error correction system, for example ECC200, allowing the reconstruction of missing data following a 30% degradation of the surface.

[0046] The Aztec code is described in ISO / IEC 24778.

[0047] The QR code is defined by the ISO / IEC 18004 standard. It also has a multi-level error correction system.

[0048] In some implementations, the QR code is static and includes a URL. When the user scans the QR code, they are redirected to a web page containing information about the positioning cushion.

[0049] Advantageously, the QR code is dynamic and contains a short URL, redirecting the user to the URL of a destination website.

[0050] In some implementations, the bidirectional code, for example a QR code or a DataMatrix, is scanned using a handheld reader connected to a terminal such as an or- a desktop computer or a mobile computer.

[0051] Advantageously, the bidirectional code is scanned using a mobile communication terminal, such as a mobile phone, tablet, or phablet, via a dedicated application.

[0052] According to various embodiments, the bidirectional code, for example QR code or DataMatrix, is placed on the positioning cushion by printing (for example by inkjet or screen printing), by laser marking, by thermal transfer, or even by micro-percussion marking.

[0053] According to a second aspect, a set is proposed comprising at least one technical support device for posture as presented above and means for reading information, these reading means being capable of reading information supported by the electronic identification means.

[0054] Advantageously, the technical posture aid device is a positioning cushion for the prevention of pressure sores, the cushion comprising padding contained in a cover, the electronic identification means comprising a linear barcode or a two-dimensional code, the information reading means comprising a linear barcode reader or a two-dimensional code reader.

[0055] In some implementations, the linear barcode or two-dimensional code is printed on the cover.

[0056] The cover is for example made of cellulose fibers, or based on cellulose fibers, or of polyurethane or of fabric coated with polyurethane, or of a polyurethane-polycarbonate mixture.

[0057] In some implementations, the linear barcode or the two-dimensional code is printed on the cover by screen printing.

[0058] Advantageously, the assembly comprises a plurality of positioning cushions of different shapes and / or different sizes and / or different paddings, each cushion being provided with a unique apparent identifier, visible to a user, the identifier being printed or reported on the cover.

[0059] The user can thus quickly verify that the cushion is indeed the one to be used, possibly in combination with one or more other positioning cushions.

[0060] The user advantageously receives details of this use in combination of cushions, by scanning the barcode of one of the positioning cushions.

[0061] For example, by scanning a QR code or a DataMatrix of a positioning cushion using a mobile communication terminal (e.g. a mobile phone, a tablet), equipped with a dedicated application, the user will have access to a set of information advantageously including a technical sheet presenting the cushion, a prescription guide, a patient mobilization guide.

[0062] This information can be displayed on the mobile terminal, under the image files (for example in pdf format), or video files.

[0063] This information can advantageously be downloaded onto the mobile terminal.

[0064] Advantageously, a set is proposed comprising a plurality of positioning cushions of different shapes and / or different sizes and / or different paddings, each cushion being provided with at least one pictogram schematically representing a part of the human body against which the cushion is intended to be in contact, the pictogram being printed on the cover or attached to the cover.

[0065] Here, pictogram means a figurative drawing, more or less realistic or stylized, used for communication purposes, without reference to spoken language.

[0066] The pictogram is for example screen printed on the cover of the positioning cushion.

[0067] According to another aspect, an information device of the client-server type is proposed, comprising at least one remote server equipped with a database and means of communication with the means of reading information of an assembly as presented above, the device comprising, on the client side, a mobile communication terminal, the database containing information on each positioning cushion of the assembly.

[0068] According to another aspect, a communication method is proposed using an information device as presented above, the method comprising a first step of reading, by the reading means, information supported by the electronic identification means such as a QR code carried by a positioning cushion, a step of sending a request to the remote server, a step of sending by the remote server, to the mobile communication terminal, specific information data for said positioning cushion, and a step of displaying said specific information on a screen of the mobile communication terminal.

[0069] In certain implementations, communication between the mobile terminal and the server is carried out by a protocol chosen from the group including protocols known under the brands Wi-Fi, Bluetooth, Sigfox, Zigbee, LoRawan, Z-Wave, the communication being advantageously wireless.

[0070] In other implementations, communication between the mobile terminal and the server is carried out via wired connection.

[0071] Advantageously, the method includes a step of selection, by the user, using the mobile communication terminal, of the specific information data for said positioning cushion, from a list of specific data contained in the remote server, the mobile communication terminal being a mobile phone, a computer, a tablet, a phablet.

[0072] Other objects and advantages of the invention will become apparent from the description of embodiments, shown below with reference to the attached drawings in which:

[0073] [Fig.1] is a front view of a positioning cushion, according to one embodiment;

[0074] [Fig.2] is a view analogous to [Fig.1] of a positioning cushion, according to another embodiment.

[0075] In the remainder of this description, the term "patient" is used to designate a person or animal whose mobility is reduced, weak or nonexistent, as a result of surgery, an accident, a pathology, or aging, whether the patient is kept at home, or treated in a medical setting, or living in a specialized facility for elderly patients, such as, for example, a nursing home.

[0076] It is understood that the invention also finds application for other technical aid devices for posture than cushions, to reduce the risks of pressure sores, for example foot lifters, heel pads, wedges, blocks.

[0077] In the remainder of this description, positioning cushions include padding, for example in the form of microbeads or fibers, particularly polyester fibers, or a mixture of beads and fibers. Microfiber padding, particularly polyester, is advantageously used for patients with reduced mobility, to position the patient and improve their comfort. Microbead padding is advantageously used for the positioning of patients with little or no mobility, for care purposes.

[0078] In the remainder of this description, the positioning cushions 1 include a cover.

[0079] Advantageously, the cover is made of polyurethane or textile (e.g., polyamide) coated with polyurethane or a polyurethane-polycarbonate blend, with a peripheral weld, preferably ultrasonically welded. These arrangements greatly reduce the risk of liquids penetrating the padding.

[0080] In other embodiments, the covers have a zipper or zip closure on at least part of their peripheral edge.

[0081] Advantageously, the cover is treated with silver ions (Ag+), reducing the risk of microorganism growth. The treatment is, for example, that offered by Sanitized AG. The Ag+ ion treatment reduces the risk of cross-infection and allows for multi-patient use of the cushions. The covers are then preferably cleaned and disinfected using microfiber wipes impregnated with a detergent or a surface disinfectant detergent.

[0082] In some embodiments, the covers are made of cellulose fibers. For example, the cellulose fibers are of the type marketed by Lenzing under the Tencel® brand. The cushions then have removable covers, which are machine washable.

[0083] Advantageously, the positioning cushions are eco-designed, and include in particular a portion of bio-based materials, i.e. renewable materials derived from plant or animal biomass.

[0084] Advantageously, the positioning cushions are offered as a product range, comprising a small number of standard cushions (e.g., crescent-shaped, snake-shaped for lateral decubitus positioning, triangular for occipital pressure relief), and modular cushions (e.g., rectangular, cylindrical, circular, or semi-circular). Advantageously, the positioning cushions form a complete range of postural support devices, with pads.

[0085] In the figures, two positioning cushions 1 of different shapes are shown in plan view on one of their external faces, each cushion 1 bearing a two-dimensional barcode 2, of the QR code or DataMatrix type, and a product reference 3 visible to the user.

[0086] In the embodiments shown, the barcode 2 and the product reference 3 are placed next to each other, and for example screen printed on the cover of the cushion 1.

[0087] The user's attention is drawn to the barcode 2, the coded data of which is intended for a reader (for example a mobile phone equipped with a dedicated application), the user seeing at the same time the product reference 3.

[0088] Reading the barcode 1 leads to access to product information, via a URL link (for Uniform Resource Locator), this information being displayed on the reader's screen.

[0089] The user can then verify that the shape of the cushion 1 placed in front of him is indeed that represented in the information visible on the screen, and that the reference of the product 3 visible on the cushion 1 is indeed that appearing in the information received.

[0090] In the embodiments shown, the product reference 3 is a number.

[0091] This number is advantageously associated in a one-to-one manner with a form of positioning cushion.

[0092] In other embodiments, not shown, the product reference is a letter (for example A to Z, or any other alphabet depending on the user's language), or an ideogram, or a set comprising a letter and / or an ideogram and / or one or more numbers.

[0093] In other embodiments, not shown, the barcode (of unidirectional or bidirectional type) and the product reference are not placed next to each other.

[0094] The one-to-one association of a product reference 3 visible on the cushion 1, with a cushion shape provides great security to the user, for several reasons.

[0095] When only one cushion is to be put in place, the user can verify that the cushion whose barcode 2 has been scanned is indeed the one provided for in the prescription, for the patient.

[0096] This verification relates to the shape of the cushion, its size and its type of padding.

[0097] The user is further guided in setting up cushion 1 for each patient. The information displayed on the screen (e.g., PDF documents, videos) educates, where necessary, a user with little or no training in the use of positioning cushions.

[0098] When a positioning cushion is to be put in place in combination with one or more other cushions, the user can check that the combination is indeed the one provided for in the prescription, for the patient.

[0099] This verification relates to the shape of the cushions, as well as their sizes and types of padding.

[0100] In certain embodiments, the barcode 2 is printed in black and white or in color on a substrate, for example a polymer material, affixed to the cushion cover, for example by gluing, welding, stapling, or sewing. The product reference 3 is printed on the same substrate as the barcode, or on another substrate affixed to the cushion cover.

[0101] Alternatively, product reference 3 is printed directly onto the cushion cover, for example by screen printing.

[0102] Alternatively, the reference 3 of the cushion is referred to the cover, for example on a label sewn onto the edge of the cover.

[0103] In other advantageous embodiments, the barcode 2 is printed directly onto the cushion cover, for example by screen printing. The product reference 3 is also advantageously printed directly onto the cushion cover.

[0104] Advantageously, the cushion 1 includes a pictogram 4 indicating the part of the patient's body against which the cushion 1 should be placed. For example, the cushion bears a pictogram of a patient's head, for an S-shaped cushion as shown in [Fig. 2], this type of cushion being used for a patient in the lateral decubitus position.

[0105] The invention has many advantages.

[0106] The user has quick access to tools and information on each positioning cushion placed within easy reach, and can thus learn about the recommended uses for the cushion.

[0107] The risks of misuse of the positioning cushion are thus reduced.

[0108] The user has access to the indications for each cushion (e.g., for which disorders, for (what objectives). Where appropriate, clinical cases may be presented. The information provided is therefore tailored to each user: a doctor or occupational therapist prescribing a postural support device for a patient, caregiver or nurse who needs to use or replace a positioning cushion, or several positioning cushions.

[0109] The risks of prescription errors or incorrect combination of cushions are thus reduced.

[0110] Advantageously, the information provided is adapted to the user's level of knowledge.

[0111] Advantageously, the user scans two (or more than two) positioning cushions, with assistance provided to enable the user to check if the two cushions are compatible, suitable for the patient, and how to position them.

[0112] The risks of incorrect cushion combination are thus reduced.

[0113] The information provided to users includes pictograms. Advantageously, the pictograms are analogous to the human body or a part of the human body, to visually locate the correct position of each cushion relative to the patient. Only the outline of the human body is drawn.

[0114] The information provided to users is thus more directly understandable than textual elements, particularly for foreign personnel.

[0115] The information provided to users also advantageously includes videos, presenting didactic examples of setting up cushions, as well as technical data sheets, instructions for use, manufacturer data, for example in pdf format.

[0116] Rapid access to a large amount of training and information data makes the use of positioning cushions easier and more immediate for care teams.

[0117] The combination of a code, for example QR code, and a product reference, for example an alphanumeric reference, improves the product learning curve.

[0118] Initially, the user will use code 2 (for example, QR code or DataMatrix) to verify that cushion 1 is indeed the correct one (or that the combination of cushions is indeed the correct one), and if necessary, will also verify that they are correctly positioning each cushion 1. During this learning process, the user will memorize links between a cushion 1 position and a product reference 3. The user gradually learns the correct actions and associates them with the product references 3.

[0119] In a second learning phase, the user will use product reference 3 to place each cushion 1, drawing on their procedural memory or motor memory. Simply by looking at product references 3, sensorimotor memory, which is a long-term memory, allows the user to automatically place the cushions 1 and visualize the actions to be performed.

[0120] The use of the positioning cushions 1 is thus made more spontaneous and natural.

[0121] The implementation of a means of electronic identification with contact and / or without contact also improves traceability.
