Definitions
- the present utility model relates to a disposable stethoscope protector that acts as a safety device to prevent cross infection through the stethoscope during the clinical examination of patients.
- This protector can be used by doctors, nurses, physiotherapists and any other healthcare professional.
- a stethoscope is a major contributor to the cross-transmission of infections between patients, as it is placed directly in contact with the skin of many patients without proper cleaning of the skin. bell and the diagram between the equipment uses with the different patients. This is especially common in hospitals and intensive care centers where several patients with different illnesses are hospitalized, who are supervised by the same medical team. In such cases, the cross-transmission of infections is especially serious, as it involves hospital bacteria and patients in very fragile health.
- PI 0705077-1, MU 8801954-3 and MU9001944-0 refer to latex devices, possibly PET, which work like a flapped lid that fits into the stethoscope's diaphragm.
- These protectors are made up of a unique structure with adequate tension to compose a kind of claw around the diaphragm, and have an ordinarily circular main portion, from which ends develop a secondary portion, containing two parallel tabs, responsible for the attachment of the protectors in the stethoscope.
- the laminar support flap presented in square format, also in latex, containing in its inferior surface, a projection to aid in the traction, said fin is an integral part of the protector, serving as a prop during opening, when the introduction and removal of the protectors.
- Protectors in the form of a cap with an opening surrounded by a rubber band which can be placed over one side of the stethoscope head - diaphragm or bell can also be known from the prior art.
- the elastic returns to the unintended state, forming folds and undulations in the protector over the side that will be used for auscultation of the patient. These folds and undulations cause interference with auscultation, which impairs the quality of the exam.
- None of the state-of-the-art documents reveal or suggest a disposable protector that envelops both sides of the stethoscope at one time, allowing the protected use of the bell and diaphragm during the examination.
- Clinical single-protector made of environmentally friendly and inexpensive material.
- the use of medical nonwoven with bacteriological barrier and sterilizable material, allowing its use even in operating rooms is an added advantage.
- none of the prior art documents suggest a guard closure system that allows it to be adjusted to different stethoscope sizes while ensuring stable attachment to the equipment.
- a disposable stethoscope protector comprising a stethoscope head housing provided with two opposing faces, each face covering one side of the stethoscope head, a diameter stethoscope head entry opening larger than said head, and a closure system disposed on one side of the housing near the opening, the shield being at least partially nonwoven material.
- the protector may be formed from a single piece of transversely folded nonwoven material forming the two overlapping sides of the housing, with the ends of the nonwoven piece opposite the fold constituting the edges of the inlet opening and the two faces of the housing are joined together along their contour between the opening edge and the transverse fold.
- the single piece of nonwoven material may be rectangular in shape and folded transversely to its largest dimension, and the side edges of the two faces that are perpendicular to the fold are respectively joined together.
- the protector may consist of two pieces of overlapping nonwoven material forming respectively the two faces of the housing, the pieces of nonwoven material having an edge constituting the edge of the inlet opening and being joined together along the rest of its outline.
- the edges of the housing faces may be joined together by one seam and heat and pressure sealing.
- the closure system may comprise a bilaminated adhesive tape having a end detachably attached to the housing surface and one free end.
- the bilaminated tape may be arranged parallel to the opening.
- the nonwoven material is a recyclable material, preferably comprises polypropylene and may be hydrophobic.
- the nonwoven material may also comprise medical use TNT with bacteriological barrier and impermeable.
- Figure 1 - a front view of the stethoscope protector according to the present model
- Figure 2 - a posterior view of the protector applied to the stethoscope, still in the open state;
- Figure 3 A front view of the protector applied to the stethoscope, already in the closed state.
- the disposable stethoscope protector has a stethoscope head housing 1, provided with two opposite faces, each face covering one side of the stethoscope head, so that When applied to the stethoscope, both the bell and the diaphragm are completely housed inside the protector.
- the shield is provided at one end with an inlet opening 2 having a larger diameter than the stethoscope head.
- the opening need not be stretched for the stethoscope to be inserted into the protector.
- the protector has a closure system for closing said aperture when the protector is in use to ensure that the protector is securely attached to the stethoscope and does not make contact with the skin of the patient to be examined.
- the protector is made of a low cost nonwoven fabric (TNT) material.
- the nonwoven material may be polypropylene based and / or may comprise a hydrophobic material in its composition.
- the protector may also be made from medical nonwoven material which has a bacteriological, impermeable and sterilizable barrier. Nonwoven material is recyclable and clean combustion to reduce the production and disposal of polluting waste into the environment.
- the protector may be comprised of a single piece of nonwoven material which is transversely folded so that each half of the piece of nonwoven material will constitute a face of the housing.
- the region of the fold preferably corresponds to the bottom of the housing 3, and the ends of the non-woven piece of material opposite the fold will constitute the edges of the inlet opening 2.
- the two faces of the housing are joined together along their contour. between the opening edge and the transverse fold to form the enclosure 1.
- this single piece of nonwoven material has a rectangular shape, and is folded transversely to its largest dimension.
- the two halves of the single piece forming the housing faces are overlapped, with the corresponding side edges 4, 6 of the two faces also overlapping respectively.
- the overlapping side edges 4, 6 of the non-woven piece of material which are perpendicular to the fold, are joined together to close the sides of the housing and provide better isolation of the stethoscope from the patient's skin.
- the finished shield will be approximately square in shape with three closed sides 3, 4, 6 and one open side 2 constituting the opening for the entry of the stethoscope head.
- the disposable stethoscope protector may be comprised of two overlapping pieces of nonwoven material which respectively form the two sides of the housing 1.
- these two parts are approximately the same in shape and size, so that they may be that the edges 2, 3, 4, 6 of all The ends of these two pieces also overlap.
- One of the overlapping ends of the two pieces of nonwoven material constitutes the edge of the inlet opening 2.
- the two pieces are joined together along the remainder of their contour. If these two pieces have a square or rectangular shape, their other side ends 4, 6 and bottom 3 will be joined together respectively.
- the edges 3, 4, 6 of the housing 1 are joined together by a manual or automated seam and / or heat sealing. and pressure in manual, semi-automatic and automatic sealing machines. Other forms of joining between these edges may also be used to ensure that the stethoscope head is completely contained within the shield housing and does not make any contact with the skin of the examined patient.
- This housing arrangement with the overlapping edges joined together is similar to an envelope which ensures that the protector is stretched even when the stethoscope head is housed inside as shown in figures 2 and 3. This is avoided. the formation of folds and ripples on the shield surface on both sides used for patient auscultation, which could cause interference with auscultation. Accordingly, the protector according to the present model does not cause any harm or interference with the quality and accuracy of the stethoscope examination.
- shield may be of various shapes, for example in the shape of a half moon, oval, circular or any other shape provided it has a border of opening allowing the introduction of the stethoscope head into the housing, and enclosing said head on its two sides.
- the protector may also have varying dimensions for use in neonatal, pediatric, clinical, adult and cardiologic stethoscopes with the high bell.
- the protector closure system preferably comprises a bilaminated adhesive tape 5 coupled to the outer surface of the protector and is oriented parallel to the opening edge 2.
- This adhesive tape 5 has an upper layer and a lower layer, both having the adhesive lower face and the non-adhesive upper face.
- the bottom layer is glued with its adhesive underside to the outer surface of the protector.
- the upper layer is initially arranged with the adhesive underside glued to the non-adhesive upper face of the lower layer.
- one end of the lower face of the upper layer is glued to the outer surface of the protector and the opposite end of the lower face is provided with a non-adhesive flap whereby the upper layer is pulled and detached from the lower layer.
- the non-adhesive flap of the upper layer must be pulled so that the upper layer is detached from the lower layer.
- This upper layer is then pulled in parallel around the opening 2 of the shield on the portion above the stethoscope head and glued to the outer surface of the shield to close it.
- This bilaminated adhesive tape 5 can also be completely peeled off and repositioned in another more suitable location of the protector if necessary.
- the adhesive tape 5 may be positioned closer to the stethoscope head to provide a firmer closure of the shield.
- This disposable stethoscope protector therefore allows the stethoscope head to be inserted through the open side 2 of the protector and subsequent closure of the stethoscope with adhesive tape 5, which adheres to the outer surface of the protector, allowing both the bell and the Stethoscope head diaphragms are covered and ready for use in the clinical examination, protecting the patient from cross infection with the use of only one disposable shield unit. After a single use, this protector should be discarded and replaced with a new one.
- the protector according to the present utility model also allows to reduce health costs and waste as it uses low cost recyclable material.
