Definitions

  • the present invention generally finds application in the field of medical and paramedical devices and particularly relates to a disposable medical device for lift and transfer of patients between ambulance stretchers and/or hospital stretchers by a healthcare professional.
  • Devices are known in the field of medical and paramedical devices, which are adapted to be positioned between a patient-supporting surface for a patient and the patient him/herself.
  • these devices comprise a substantially sheet-like support structure which extends to such a length as to be able to support the entire body of the patient, and has a peripheral portion having the longitudinal and the transverse edges.
  • the support structure comprises a top surface and a bottom surface, which are intended to contact the body of the patient and the surface that supports him/her respectively.
  • the peripheral portion of such devices has hand grips which are adapted to be grasped by at least one healthcare professional during patient transfer maneuvers between two different support surfaces, preferably between an ambulance stretcher and a hospital stretcher.
  • a first drawback of these known devices is that the support structure is made of a material that is re-usable after first use and has to undergo washing, disinfection and sterilization treatments, which increase manufacturing and maintenance costs.
  • a further drawback of these devices is that the support structure generally has no liquid-absorbing inserts preventing leakage of body fluids of the patient outside the device, which increases injury hazards for the healthcare professional due to slipping.
  • devices which have a sheet structure comprising a plurality of mutually joined layers, at least one whereof is of absorbent type.
  • WO2018132776 discloses a device for lift and transfer of patients which comprises a sheet structure with an upper layer having a high liquid-absorbing ability and a lower layer having a relatively low coefficient of friction to facilitate the sliding movement of the patient along a patient-supporting surface.
  • the peripheral edge of this known device has handles formed thereon, which are adapted to be folded inwards toward the sheet structure, to allow the device and the patient to be lifted and moved.
  • a first drawback of this solution is that the presence of foldable handles only partially assists the movement of the patient and will not prevent him/her from interfering with the handles as he/she is being moved.
  • a further drawback of this solution is that the layers that compose the sheet structure are made of air-permeable polyester fabric and nylon fabric or smooth polyester, respectively, which prevent simple sterilization of the device.
  • devices for lift and transfer of patients have been developed, which have a plurality of openings adapted to be grasped by one or more healthcare professionals and to assist the movement of the device and the patient.
  • GB2484885 discloses a disposable device for lift and transfer of patients that can be used in the medical field and has a multi-layer sheet structure comprising a liquid permeable upper layer intended to contact the patient, an intermediate absorbing layer and a liquid-impermeable lower layer.
  • This device also comprises a plurality of handles or openings arranged along the longitudinal extent of the device.
  • the layers of the sheet structure are coupled together by heat sealing on the peripheral portion thereof to avoid leakage of body fluids of the patient outside the device.
  • US5577281A discloses another device for lift and transfer of patients.
  • the technical problem addressed by the present invention is in short to simplify the operations for lift and transfer of patients between ambulance stretchers and/or hospital stretchers thereby reducing the risk of injury for healthcare professionals.
  • the object of the present invention is to obviate the above drawbacks, by providing a disposable device for lift and transfer of patients between ambulance stretchers and/or hospital stretchers by a healthcare professional, that is highly efficient and relatively cost-effective.
  • a particular object of the present invention is to provide a disposable device for lift and transfer of patients of the aforementioned type that can reduce the risk of injury to the healthcare professionals that are to use it.
  • a further object of the present invention is to provide a disposable device for lift and transfer of patients of the aforementioned type that does not require any particular skill of a healthcare professional during the handling operations.
  • Another object of the present invention is to provide a disposable device for lift and transfer of patients of the aforementioned type that has reduced overall dimensions.
  • a further object the present invention is to provide a disposable device for lift and transfer of patients of the aforementioned type that can prevent leakage of body fluids of the patient outside the device.
  • Yet another object of the present invention is to provide a disposable device for lift and transfer of patients of the aforementioned type that can reduce the risk of injury to the healthcare professionals, due to slipping.
  • the openings are conveniently arranged along the edges at predetermined distances from each other, which are calculated in combination both with the biometric parameters of the patients being transported and the maximum loads that can be acceptable for healthcare professionals having different muscular strengths, and allowed by injury-prevention regulations.
  • the distances are differentiated along the longitudinal extent of the supporting structure and are equal to a substantially constant value proximate to the head and to higher and increasing values proximate to the torso and limbs of the patient.
  • This combination of characteristics can simplify the operations for lift and transfer of patients between ambulance stretchers and/or hospital stretchers thereby reducing the risk of injury for healthcare professionals.
  • a disposable medical device for lift and transfer of patients between ambulance stretchers and/or hospital stretchers by a healthcare professional W.
  • the disposable device 1 may be stored within a rescue ambulance having at least one stretcher B and be designed to cover the mattress thereof before the latter will receive a patient.
  • the healthcare professionals W in the ambulance and/or those at the EMS shall transfer the patient from the ambulance stretcher B to the hospital stretcher B for the patient to receive appropriate care.
  • the device 1 comprises a sheet support structure 2 extending along a longitudinal direction and to such a length as to be able to support the entire body of a patient.
  • the support structure comprises a peripheral portion 3 with longitudinal edges 4 and transverse edges 5.

  • the sheet structure 2 is formed with a multilayer textile material having at least one first layer 8 and at least one second layer 9, which are coupled together.
  • the sheet structure 2 may be made of UNECE 118/2012-compliant, latex-free, high-temperature resistant SMMS non-woven fabric.
  • the disposable device 1 may be belt or rolled on itself to reduce storage space and remain inside the rescue ambulance even under relatively high temperature conditions while avoiding any damage or aging thereof.
  • first layer 8 and the second layer 9 can be coupled along the longitudinal edges 4 and the transverse edges 5 of the peripheral portion 3 by means of heat or R.F. sealing.
  • the layers 8, 9 may be coupled together also proximate to the edges 4, 5 to define the extent of the peripheral portion 3 and thereby restrict it to a strip 3'.
  • the first layer 8 which defines the top surface 6 comprises an absorbent layer that has a maximum carrying capacity of more than 150kg even when wet.
  • the first layer 8 includes at least one liquid-absorbing insert 10 inserted in an approximately central position of the support structure 2 corresponding to the lumbar region of the patient.
  • the second layer 9 that defines the bottom surface 7 is an impermeable layer to retain liquids collected by the insert 10 and has a longitudinal central portion 11 corresponding to the lumbar region of the patient.
  • the central portion 11 has a length l 3 that ranges from 800 mm to 1200 mm and is preferably about 1000 mm.
  • the second layer 9 may have a low surface friction coefficient.
  • the disposable device 1 falls in the class of non-invasive devices (Class I) suitable for contact with injured skin and used as a mechanical barrier and for the absorption of exudates under Leg. Dec. No. 46/97 (pursuant to EEC Directive 93/42).
  • the disposable device 1 helps to reduce the consumption of chemicals for cleaning/disinfection of the mattresses of the stretchers B, and avoids contact with any residues of such substances by the patient and healthcare professionals W, as required by Leg. Dec. No. 81/08 and by S.M.I., namely for healthcare professionals, risk of exposure to chemical agents, Title IX.
  • This particular feature can also avoid the microbiological risk for patients and healthcare professionals as required by Leg. Dec. No. 81/08 and S.M.I., namely for healthcare professionals, risk of exposure to infectious agents, Titles I and X.
  • the peripheral portion 3, and hence the strip 3' has a plurality of openings 12 adapted to define hand grips designed to be grasped by one or more healthcare professionals W to facilitate lift and transfer of the patient.
  • the openings 12 are arranged along the longitudinal edges 4 and are placed at predetermined distances d 1 , d 2 , d 3 .
  • the predetermined distances d 1 , d 2 , d 3 are differentiated along the longitudinal extent of the support structure 2 with a substantially constant value d 1 proximate to the end zone that is intended to support the head and with progressively increasing values d 2 , d 3 proximate to the end zone intended to support the torso and the lower limbs of the patient.
  • the openings 12 formed along the longitudinal edges 4 of the supporting structure 2 are located at distances d 1 , d 2 , d 3 calculated with the relation d 1 ⁇ d 2 ⁇ d 3 .
  • the support structure 2 will comprise first openings 12' spaced apart from each other at a constant distance d 1 and second openings 12" spaced apart from each other at a distance d 3 and spaced apart from the first openings 12' at a distance d 2 .
  • the arrangement of the openings 12 along the longitudinal extent of the support structure 2 is calculated in combination both with the biometric parameters of the patients being transported and the maximum loads acceptable for healthcare professionals W having different muscular strengths, and allowed by injury-prevention regulations.
  • maximum loads acceptable for healthcare professionals having different muscular strengths shall be intended as the maximum loads acceptable for healthcare professionals as regulated by Leg. Dec. No. 81/08 and S.M.I., namely, for healthcare professionals, Injury prevention risk, Title III Arts. 69, 70, 71.
  • the maximum loads acceptable for healthcare professionals W are also derived from the so-called "lifting risk assessment with the NIOSH" for the assessment of the risk and prevention of musculoskeletal disorders due to professional biomechanical load.
  • the maximum acceptable loads can be directly derived according to a predetermined angle ⁇ close to 135°, which is considered as the angle between the shoulders A and each arm B and the angle between the arm B and the forearm C that the healthcare professional W must hold to lift and transfer a patient without incurring musculoskeletal injury, as schematically shown in FIG. 4 .
  • the predetermined distances d 1 , d 2 , d 3 of the openings 12 has been calculated based on the Leg. Dec. No. 81/08, the NIOSH method and experimental field-tests that have led to the determination of the predetermined angle ⁇ .
  • the predetermined distances d 1 , d 2 , d 3 of the openings 12 have been calculated while accounting for the different sizes and muscular strengths of male healthcare professionals W 1 and female health operators W 2 , as best shown in FIG.4 .
  • the openings 12 are arranged at a predetermined distance d 1 , about 260 mm at the longitudinal edges 4 and proximate to the zone of the sheet structure 2 that is adapted to receive the head of the patient.
  • the openings 12 formed at the longitudinal edges 4 and proximate to the torso and limbs of the patient are arranged at a predetermined distance d 2 , d 3 of about 550 mm and 710 mm respectively.
  • the openings 12 are formed also at the transverse edges 5 proximate to the head and limbs of the patient.
  • the support structure 2 comprises third openings 12′′′ arranged along the transverse edges 5 and placed at a predetermined distance d 4 , which is preferably shorter than the distance d 2 and longer than the distance d 1 and equal to about 350 mm.
  • This combination of features allows a healthcare professional W to grasp the openings 12 of the disposable device 1 at shorter distances at the head, torso and lumbar regions of the patient to withstand a heavier load.
  • the sheet support structure 2 comprises a downwardly folded zone 13 at least at one edge 4, 5 of the peripheral portion 3, which zone 13 defines a pocket 14 adapted to engage the stretcher B on which it is laid.
  • the pocket 14 may receive a portion B' of the stretcher B to facilitate positioning of the device 1.
  • the pocket 14 has a length l 4 of about 230 mm and a width l 2 equal to that of the device 1.
  • the pocket 14 is formed proximate to the region of the sheet structure 2 that is adapted to receive the head of the patient, thereby allowing the device 1 to be adapted to any type and size of the mattresses of currently available stretchers B.
  • the device 1 comprises a third cover layer 18 that can be removably coupled to the first layer 8 by a continuous zipper 15 to define an inner compartment adapted to entirely contain and/or protect the patient.
  • the inner compartment may be at least partially closed by the continuous zipper 15, for example to allow transfer of the patient to the morgue.
  • the continuous zipper 15 may comprise toothed edges 16, 17 that can be closed by means of a slider, not shown, to allow the structure 2 to be coupled with the third layer 18.
  • a toothed edge 16 may be rigidly joined to the first layer 8 and the other toothed edge 17 may be rigidly joined to the peripheral edge 19 of the third layer 18.
  • the zipper 15 may be installed proximate to the strip 3' to allow the operator W to grasp the plurality of openings 12 even when the cover layer 18 is coupled to the structure 2.
  • the third covering layer 18 may be also made of SMMS non-woven fabric associated with polyethylene PE and the zipper 15 may be of impermeable type.
  • the disposable device for lift and transfer of patients fulfills the intended objects, and in particular can simplify the operations for lift and transfer of patients between ambulance stretchers and/or hospital stretchers, thereby reducing the risk of injury for health professionals.
  • the present invention may find application in industry, because it can be produced on an industrial scale in factories for manufacturing class I medical devices.
