Lifting sling

The present invention relates to a lifting device, and more particularly to a lifting sling device

Lifting slings are typically used to carry patients or people with reduced mobility. A key issue in the use of lifting slings is to prevent accidents and avoid cross-contamination between patients. The earliest lifting slings were made of woven fabrics, which are not only expensive but also prone to cross-infection. Patent CN 1184628 A discloses a disposable or limited use hoist (not equivalent to a lifting sling device herein) made of a nonwoven material. Since the price of the nonwoven material is a fraction of the price of the textile material and has the same load carrying capacity, the special purpose of the hoisting device is realized, thereby avoiding the risk of cross infection. However, a new problem has arisen from how to dispose of discarded slings. The discarded hoisting equipment is usually landfilled or incinerated, and the gas generated during the incineration process can pollute the environment. If the hoisting device is not biodegradable, the landfill will also cause damage to the environment.

Among the currently common biodegradable polymers, the advantage of polylactic acid (PLA) in the biodegradable/compostable polymers for plastics and fabrics is that, although PLA is extracted from natural and renewable materials, However, it is thermoplastic and can be extruded by melt to produce plastic products, fibers and fabrics, similar materials based on petroleum synthesis, such as polyolefins (polyethylene and polypropylene) and polyester (polyethylene terephthalate). PLA articles have good mechanical strength, toughness and softness compared to alcohol esters and polyethylene terephthalate. PLA is made of lactic acid, which is a fermentation by-product extracted from corn, wheat, grain or sugar beet. When the polymerization is formed, the lactic acid forms an aliphatic polyester having the dimer repeating unit shown below: (1)

Poly(polyhydroxyalkyl acrylate) (PHA) has been found to be made by the natural synthesis of a variety of bacteria as intracellular storage materials for carbon sources and energy sources. The copolyester repeating unit of P(3HB-co-4HB) is as follows: (2)

Polyadipate-butylene terephthalate (PBAT), a biodegradable polymer, is currently not available from bacterial sources, but can be synthesized from petroleum-based products. Although PBAT has a melting point of 120 ° C, which is lower than the melting point of PLA, PBAT has higher elasticity than PLA, excellent impact strength and good melt processing properties. Although PLA has good melt processing properties, strength and biodegradation/composting properties, its elasticity and impact strength are not good. Blends of PBAT and PLA have enhanced elasticity, flexibility and impact strength. The chemical structure of PBAT is as follows: (3)

Polybutylene succinate (PBS) can be synthesized by polycondensation of ethylene glycol. The chemical structure of PBS is as follows: (4)

In order to make the objects, technical solutions and advantages of the present invention more comprehensible, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to be limiting.

The present invention relates to a body support lifting sling, wherein the fabric in the lifting sling is made of a biodegradable polymer material, which can prevent cross infection between patients, and can also support the lifting sling due to body support. Biodegradable and/or compostable, so that the body support lifting slings discarded after use do not pollute the environment. Because the sling device supports the back and thigh of the patient, the patient is suspended from the hoist by a detachable suspension such as a sling or the like.

The sling device is preferably a one-piece body support sling device that supports the patient's back and thighs. The suspension member is required to have at least four points attached, two of which are located on the side of the sling device in the corresponding shoulder region and two at the bottom end of the sling device between the two legs of the patient. The other two optional additional suspension members are located at the bottom of the sling device and outside the fabric of the sling device in each leg region of the patient, with attachment points on each side of the sling device, but preferably not Too close to the patient's leg to avoid contact with the patient's leg during lifting, the use of the additional suspension enhances safety during patient lift and gives the patient a greater sense of security. If the patient's legs are too wide, or too delicate or sore, and do not risk any contact with the optional external suspension, the two optional suspensions will not be used, but each suspension will be folded back and Put into the belt loop. The suspension preferably includes a lower end portion for supporting a body portion of the person and a depending leg, the lower end portion extending downwardly and downwardly between the thighs of the patient, respectively. The sling also has a head support extension at the upper end. In this case, the sling may also have two additional attachment points in the head region, or may have one or more reinforcement members extending substantially through the extension portion and beyond the connection sling device at a distance Corresponding to the connection point of the attachment point of the sling device in the shoulder area.

The sling is also provided with a javelin-shaped portion or other shape so that it can be more conformed to the human body shape during lifting. Reinforcement and/or padding can also be done in the area.

1 is a side perspective view of a lifting sling device and a patient in accordance with an embodiment of the present invention. As shown in Fig. 1, a single piece sling apparatus 10 is shown, including a body portion 11 having a support portion 12 of a hanging leg at a lower end and a head support extension portion 13 at an upper end. The support portion 12 of the overhanging leg extends downwardly and upwardly between the two thighs of the patient, respectively, and supports the head H of the patient through the head support extension portion 13, which supports the back and shoulder of the patient I . A short extension strap 14 provided with a hanger is sewn into the corresponding region of the patient's shoulder, and the suspension strap 15 is similarly sewn to the end of the support portion 12 of the overhanging leg. Additionally, an optional suspension strap 25 is attached to the lower end of the body portion 11 and outside of the fabric of the sling device corresponding to each leg of the patient to ensure safety about the pivot 12. If the suspension straps 25 are not used, they are folded back and passed through the belt loop 26.

The sling device 10 is preferably provided with a raised pattern formed by rolling (calendering) to give it the appearance of a woven fabric. The sling device 10 can be reinforced by an accessory fabric layer, in the region of the accessory fabric layer, the suspension straps 14, 15 and the optional suspension straps 25 are sewn to the sling device, and the support portion 12 of the overhanging legs can be There is a cushion between the two layers of the nonwoven fabric lifting arm to increase patient comfort. The cost of these slings is a fraction of that of a textile sling. If the sling is used a limited time, the device can be set up for personal use to prevent cross-contamination.

In order to support the head support extension 13, the sling device may have one or more stiffeners on the substrate that extend over the entire extension 13 and that extend at a distance from those locations on the extension strip 11. Alternatively, there may be an area corresponding to the head to which the two suspension straps (not shown in Fig. 1) are connected.

As shown in Figure 1, the body support lifting sling device further includes a lifting device 20, Figure 1 shows the outer end of the boom 21, and the hanger 22 is connected to the arm by a fork connector, the connection The device 23 is housed in a bearing 24, the ends of which are provided with a vertical pivot and pivotally connected to the hanger 22 at position 23a. That is, the hanger 22 can be pivoted about the rigid vertical axis at the outer end of the arm 21, and the hanger 22 and the connector 23 are rotated about the vertical axis as a whole, and the hanger 22 can be pivoted around the connector 23. The rotation of the lateral level axis pivot determined by the shaft position 23a.

Ideally, the sling device cannot be cleaned, which will avoid repeated use. To this end, it is envisaged that the seam is strong and the strap is attached to the sling device with a detachable wire so that if attempted to clean, the sling device will separate.

The present invention is not limited to a single-piece lifting sling device, but can also be used for other lifting sling devices. Moreover, the one-piece lifting sling device does not always have a support head extension 13.

A breathable or non-breathable film can also be laminated to one or both sides of the biodegradable nonwoven fabric of the sling to contain any bodily fluids of the patient during lifting and handling.

In order for the discarded lifting sling device that is no longer used to have no negative impact on the environment, the fabric in the sling device is a biodegradable and/or compostable fabric. The above biodegradable and/or compostable fabrics are discussed below. The biodegradable material used in the novel can ensure that the sling device has the corresponding load-bearing capacity, preventing accidents during lifting, and does not increase the manufacturing cost of the sling device, so that the patient can afford the person. A dedicated lifting sling to avoid cross-infection.

Although P(3HB-co-4HB) products have been shown to be readily biodegradable in soil, sludge and seawater, the rate of biodegradation in water is very slow due to the lack of microorganisms in water (Saito, Yuji, Shigeo Nakamura, Masaya Hiramitsu and Yoshiharu) Doi, "Microbial Synthesis and Properties of Poly (3-hydroxybutyrate-co-4-hydroxybutyrate)," Polymer International 39 (1996), 169-174). Therefore, the shelf life of the P(3HB-co-4HB) product should be very excellent in a clean environment such as dry storage of a sealed package, a cleaning solution, and the like. However, discarded P(3HB-co-4HB) fabrics, films and packaging materials when placed in a dirty environment containing microorganisms such as soil, river water, river mud, sea water, and compost of fertilizer and sand, sludge, and seawater. It should be easily degraded. It should be noted that polylactic acid (PLA) is not readily biodegradable in the above dirty environment and at ambient temperatures, but must be composted. First, the heat and humidity in the compost pile must break down the PLA polymer into smaller polymer chains and finally break down into lactic acid. Microorganisms in compost and soil consume smaller polymer fragments and lactic acid as nutrients. Thus, a polyhydroxyalkanoate (PHA) mixture such as a P(3HB-co-4HB) product with PLA should enhance the degradation of products made from blends of PHAs-PLA. Additionally, products made from blends of PHA and PLA should have enhanced shelf life in a clean environment. However, in the past 10 years, the price of PLA has been drastically reduced to a little higher than synthetic polymers such as polypropylene and PET polyester; at the same time, the price of PHAs continues to be 2 to 3 higher than that of PLA. The PLA can be synthesized on a large scale from lactic acid. PHAs are made from bacteria with a specific carbon source and must be extracted from bacteria using a solvent. Therefore, it is commercially impossible to mix more than 25% of PHA with PLA to form products by melt extrusion, such as woven fabrics, knitted and non-woven fabrics, films, food packaging containers and the like.

The laminated structure of the biodegradable nonwoven fabric, the biodegradable film, and the nonwoven fabric and the biodegradable film is shown in Table 1. A pure PBAT film having 9 micrometers (μm) and a 9 μm PBAT film having 20% calcium carbonate are available from suppliers in China. Meltblown (MB) Vistamaxx® (non-biodegradable) containing 20% polypropylene (PP) (non-biodegradable) is available from Biax-Fiberfilm, USA. A black spunbond (SB) PLA with carbon black of a typical quality of 80 g/m2 is available from the Saxon Textile research structure in Germany. In a separate test, a pure PBAT film and a PBAT film with 20% calcium carbonate were laminated to Vistamaxx MB and black SB PLA containing 20% PP using a hot melt adhesive of 5-13 g/m2. A hot melt bond of 0.5-12 g/m2 and preferably a hot melt bond of 1-7 g/m2 should be used. In addition, two layers of SB PLA were laminated and adhered using a melt adhesive. The weight, thickness, toughness, elongation at break, tear strength, burst strength, water vapor transmission rate (MVT) and hydrohead tested for all raw materials and laminate structures are shown in FIG. It should be noted that these are just a few examples of different embodiments of the present invention, and that different layers of the following materials are bonded together using a molten application: PBAT film or other biodegradable/composted film that can be directly applied by extrusion coating No adhesive is required on the substrate. The laminate structures can be joined or bonded together by, but not limited to, hot spot calendering, bulk calendering, or ultrasonic welding. Additionally, instead of a molten adhesive, it is possible to bond the laminate structure together using a glue or water or solvent based adhesive or latex.

As shown in Table 1, a 9 μm pure (100%) PBAT film (Sample 1) had good elongation in the MD direction and an elongation at break in the CD direction of 300% or more. The burst strength test could not be performed on samples 1 through 5 because all of these films and laminates were very elastic, did not break during testing and did not exhibit deformation after testing. The permeable vapor rate of Sample 1 was quite good at 3380 g/m ² per 24 hours while the static head was 549 mm. PBAT film (Sample 2) with 20% calcium carbonate (CaCO ₃₎ has a profile similar to the sample, wherein the WVTR and the head are relatively lower. PBAT films similar to Samples 1 and 2 and having a thickness of 6 μm or less are also expected to have good elongation and higher WVTR, although the head may be lower. Meltblown sample 3 contains 80% Vistamaxx® (Vistamaxx polyolefin based polymer with high elasticity and made of ExxonMobil) and 20% PP because the fabric is moderately open and therefore has approximately 300% MD and CD Elongation and high WVTR of 8816 g/m ² per 24 hours. Although MB Vistamaxx fabric is not biodegradable, it is an example of an elastic nonwoven material that is likely to be made from biodegradable polymers such as PBAT and others with very high elongation and deformation recovery capabilities. Biodegradable polymer. The water head of Sample 3 was quite high at 1043 mm, indicating that it had good barrier properties. It should be noted that 20% of the PP was added to the Vistamaxx polymer particles and physically mixed before the blend was fed into the MB extruder and melted so that the Vistamaxx MB fabric did not become too viscous. If melt blown 100% Vistamaxx, it will be very viscous and may agglomerate during rolling and is difficult to un-wind in subsequent lamination or use.

The laminate structure using hot melt adhesive and pure PBAT with Vistamaxx and PBAT with 20% CaC03 significantly increased MD and CD toughness compared to Vistamaxx alone. The sample also had very high MD elongation and especially high CD elongation (390% for sample 4 and 542% for sample 5). Samples 4 and 5 also had significantly higher MVTR values of 1671 and 1189 g/m2 per 24 hours, respectively, with high heads of 339 and 926 mm water, respectively. It should be noted again that the PBAT film has been able to directly compress the coating onto MB 100% Vistamaxx or MB Vistamaxx with some PP and with or without hot melt adhesive, and the extrusion coating has allowed thinner use. The PBAT film of the specification, as low as 4 or 5 μm, thus has a higher MVTR, but may have a lower head.

The black SB PLA has a target weight of 80 g/m2, a MD toughness of 104 N and a CD toughness of 31 N, but has a lower MD elongation at break of 3.6% and a high CD elongation of 30.7%. The bursting strength is 177 KN/m2 and the WVTR is quite high, 8322 g/m2 per 24 hours, and the head is quite obvious, 109 mm. The 80 gsm black SB PLA laminated to pure PBAT using a hot melt adhesive had higher MD and CD toughness than the pure SB PLA, respectively, which were 107 and 39 N, respectively, but the CD elongation was only 9.8%. However, PBAT laminated with SB PLA has a higher bursting strength of 220 KN/m2. However, the gas permeability remains excellent, with a WVTR of 2459 g/m2 per 24 hours and a very high head of 3115 mm water. SB PLA laminated with PBAT containing 20% CaCO3 had similar properties as Sample 8, except that the head was relatively low, although still up to 2600 mm water. SB PLA laminate with thinner PBAT film and a thinner PBAT film, especially formed by extrusion coating deposition, can be used for protective clothing for medical, industrial or sports applications with high MVTR. And has a high net head for barrier protection. The barrier protection can be further enhanced by applying a finish (fluoroquinone or other type of finish) to the SB PLA on either the PBAT film side or on either side of the PBAT film side. Barrier protection can also be enhanced by laminating MB PLA with SB PLA before or after lamination of the film. It is also possible to add a finishing agent to the polymer melt used to prepare, for example, a PBAT film, SB or MB PLA.

When two layers of SB PLA were bonded together to form Sample 9, the MD and CD toughness and burst strength were substantially twice that of the one-layered sample 6. The target MD and CD toughness of the elongation at break (% elongation) of the patient lift sling generated from 110 g/m2 SB PP are 200 and 140 N, respectively, at least every 5 cm, and the elongation values in MD and CD are at least 40%. As shown in Table 1, the MD bond toughness of the two bonded SB PLA layers was 215 N, but the CD toughness was only 50% of the desired level. Moreover, the elongation at break of MD and CD is much lower than the required minimum of 40%. The MD and CD elongation of SB PLA can be enhanced by blending PLA with 5 to 60% PBAT or preferably 20 to 50% PBAT prior to extrusion of the SB fabric. Additionally, PBAT and PBS can be blended with PLA to obtain a fabric having the desired MD and CD toughness and elongation values as well as stability after heat exposure. In addition, the SB long screen can be bonded by a non-hot spot calendering process to achieve greater multi-directional strength and elongation to include hydroentangled and needled. A needled SB PLA of 110 g/m2 and greater weight can be produced without the need to laminate or bond two or more SB PLA fabrics together to achieve the desired strength and elongation values.

It has also been shown that slings made of biodegradable/compostable fabrics such as PLA, from the raw material stage to the polymer formation of the plant, produce much lower greenhouse gas emissions such as carbon dioxide. For example, in the production of PLA polymers, 1.3 kilograms of carbon dioxide is produced per kilogram of polymer, and correspondingly, producing 1.9 kilograms of carbon dioxide per kilogram of PP and producing 3.4 kilograms of carbon dioxide per kilogram of PET produced. And from the raw material stage to the production of polymer plants, PLA uses less non-renewable energy, producing Ingeo brand PLA, using 42 MJ of non-renewable energy per kg of polymer, compared to PP production. At 77 megajoules of non-renewable energy per kilogram of polymer, 87 megajoules of non-renewable energy per kilogram of polymer used in PET production ("The IngeoTM Journey, NatureWorks LLC Brochure Copyright 2009).

The sling device is made of a non-biodegradable/compostable material, typically PLA, or a blend of PLA with a small amount of PHA, or a portion of PLA with a small amount of PHA and PBAT. The blend, or a major portion is a blend of PLA plus a small amount of PHA, PBAT and PBS, or a blend of PLA with a small amount of PBAT and PBS, or a blend of PBAT and PBS. The sling is cut to a shape more conforming to the patient I, and a javelin-shaped portion 16 is also provided in the sling 10 for the patient to feel more comfortable.

Typically, the sling is made by thermally bonding randomly oriented biodegradable/composted polymer fibers, but may also be made by dry-laid, chemically bonded (biodegradable adhesive) fabrics. Or made of dry-laid or spunlaced (hydroentangled) fabric. The material is generally breathable (unless a non-breathable biodegradable film adheres to it) but does not pass through the water and may require perforations in the sling for lowering the patient into the bath.

It is to be understood that those skilled in the art can make modifications and changes in the light of the above description, and all such improvements and modifications are intended to fall within the scope of the appended claims.
