Description

Manual lifting sling device

This invention relates to lifting devices and, more particularly, to a manual lifting sling device.

Hospitals often use lifting slings 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, and the structure was complicated and the design was not reasonable enough, which made the products costly.

Therefore, these lifting slings are required to be reused due to cost problems, so that cross-infection is inevitably apt to occur. The washing process of slings made of woven fabrics does not always kill the organism causing the infection, especially when washing with the temperature that the sling can withstand. Therefore, when the textile sling is washed or even dried at a temperature higher than the sling can withstand in an attempt to kill all infectious organisms, it will cause damage to the sling. The sling may also be lost or damaged when transported between the place of use and the washing location, so it is necessary to prepare enough spare slings for the patient to use when some slings are being washed or transported. Some hospitals prohibit the use of slings based on the resulting adverse effects. If the cost of the lifting sling device can be reduced, it will be advantageous to promote the one-time or limited-use lifting sling device, thereby solving the problem of cross-infection between patients.

2 is a schematic view showing the state of use of the manual lifting sling device in accordance with a preferred embodiment of the present invention. The patient is seated in the space enclosed by the manual lifting sling device, and the sling supports the back, buttocks and legs. The manual lifting sling device was lifted by two people. Each of them grabs two handles on each side of the sling, one of which supports the patient's back and the other of which supports the patient's buttocks And legs.

The invention can be made from woven or nonwoven fabrics. It is preferably made of a non-woven fabric, and a non-woven fabric may be provided with a convex pattern formed by rolling (calendering) so as to have the appearance of a woven fabric. The sling device can be reinforced by an accessory fabric layer. The manual lifting sling device provided by the present invention, although the recommended safety weight is 120 kg, has been tested to withstand 50 times of lifting 190 kg of weight without any signs of wear.

In addition, the fabric may be laminated from one or more layers of woven or nonwoven film. A breathable or non-breathable film can also be laminated to one or both sides of the biodegradable nonwoven fabric of the sling to absorb any bodily fluids of the patient during lifting and handling.

The fabric can be hydroentangled or A needled continuous continuous wire mesh or staple fiber mesh. The fabric can be made from a continuous length of wire mesh or staple fiber web bonded using non-biodegradable or biodegradable chemicals, including latex adhesives or adhesives.

In order to prevent the discarded manual lifting sling device from being used without adversely affecting the environment, the fabric in the manual lifting sling device preferably employs a biodegradable and/or compostable fabric. The above biodegradable and/or compostable fabrics are discussed below. The biodegradable material used in the invention can ensure the sling device has the corresponding carrying capacity, prevent 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.

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:

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:

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:

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

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 be PLA polymer Decomposes into smaller polymer chains and finally decomposes 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 5-13 g/m2 hot melt adhesive. A hot melt adhesive of 0.5-12 g/m2 and preferably a hot melt adhesive 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 invention, and that different layers of the following materials are bonded together using a molten application: a PBAT film or other biodegradable/composted film that can be directly extruded through a coating The substrate is applied without the need for an adhesive. The laminate structures can be joined or bonded together by, but not limited to, hot spot calendering, bulk calendering, or ultrasonic welding. Alternatively, instead of a molten adhesive, a glue or water or solvent based adhesive or latex can be used to bond the laminate structure together.

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 cannot be performed on samples 1 to 5 because all of these films and laminate structures are very elastic and are tested. It does not break during the process and does not show deformation after testing. The permeable vapor rate of Sample 1 was quite good at 3380 g/m2 per 24 hours while the static head was 549 mm. A PBAT film with 20% calcium carbonate (CaCO3) (Sample 2) had similar data to Sample 1, where both the WVTR and the hydrostatic head were 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/m2 every 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 a hot melt adhesive and a pure PBAT with Vistamaxx and a PBAT containing 20% CaC03 significantly increased MD and CD toughness compared to Vistamanx 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 target weight of black SB PLA is 80g/m2, MD toughness is 104N and CD toughness is 31N, but with a lower MD elongation at break of 3.6%, and a high CD elongation of 30.7%. The burst strength is 177 KN/m2 and the WVTR is quite high, which is 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 heat-melting 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 burst strength of 220 KN/m2. However, the gas permeability remains excellent, the WVTR is 2459 g/m2 per 24 hours, and has 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 the 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 required 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, a process that can be rolled by non-hot spots Bond the SB long screen 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.

In Table 2, two SB PLA fabrics were compared, one consisting of 100% PLA and the other consisting of a quality percentage of 80% PLA and 20% PHB. The table shows that the mixture of 80% PLA/20% PHB has better MD and CD toughness than 100% PLA SB, and the MD elongation is 4 times that of 100% PLA SB, and the CD elongation is 100% PLA SB. 3 times. The two samples 11 of Table 1 were laminated using hot melt adhesive to prepare Sample 9 in Table 1, and the thus obtained fabric had very high MD and CD tensile strength and tear strength, and higher elongation as compared with the aforementioned Sample 9. rate.

The present invention has been described in terms of a particular embodiment, and it will be understood by those skilled in the art that various changes and equivalents can be made without departing from the scope of the invention. In addition, many modifications may be made to the invention without departing from the scope of the invention.
