Definitions
- the invention relates to systems and methods for precleaning soiled articles prior to final cleaning in conventional washing machines.
- the invention also relates to fluid dispensers, and more particularly, to fluid dispensers for introducing a cast solid detergent from a reservoir into a stream of water passing through the dispenser.
- soiled articles such as diapers, hand towels, washcloths, personal linens, general bed linens, and bedpans soiled with human waste products and fluids such as feces, urine and other bodily fluids, must be rinsed to remove gross waste product prior to washing the articles in conventional washing machines.
- Chemical product dispensers for cleaning which introduce and dispense in a main stream of fluid a second fluid, such as soap or detergent, or other chemicals mixed in a liquid solution.
- Soap dispensers are commonly used for introducing soap into a stream of water which is dispensed by nozzle or is used to drive a water wheel in a rotary scrub brush.
- Soap dispensers of that type suffer from a number of disadvantages including relatively high cost of manufacture, difficulty of cleaning the parts and a relatively large number of parts. More significantly, with the emergence of cast solid detergents, a need exists for a simple way of dissolving the cast detergent and delivering it in known concentrations over a substantial period of time.
- Solid soap dispensers are generally known in the art, and typically take the form such as disclosed in U.S. Pat. No. 2,624,619, issued to Fletcher et al.
- the Fletcher et al. device is designed to dissolve a block or cylindrical detergent having uniform hardness.
- Fletcher et al. discloses a reservoir in which the solid detergent is placed. Water enters the top of the reservoir and is forced downwardly into the reservoir containing the soap.
- Sanchez utilizes a rotatable control valve which has three positions. In the first position, no fluid passes through the device whatsoever and may be considered a fail safe off position. In a second position water flows into the reservoir containing soap, and allows it to be mixed with the main flow of fluid and exit the reservoir to be applied to the object to be cleaned. In a third position, water is allowed to pass through the device without encountering the soap in the reservoir, thus providing a "rinse" function. While Sanchez provides multiple valve positions, there is only one valve position that permits mixing with the soap solution, and so it does not address the problem of adjustably and predictably controlling the concentration of the solution under varying conditions. Since
- Fletcher et al. is intended to be used with a liquid soap solution, they do not address the problem of dealing with a highly concentrated caustic solution which must be eroded in a precise manner over a long period of time.
- the present invention addresses the problem of odor control and the unsanitary conditions associated with rinsing articles such as diapers, hand towels, washcloths, personal linens, general bed linens and bedpans soiled with human waste products.
- the present invention provides a method for rinsing, precleaning, sanitizing, and/or deodorizing soiled articles prior to final cleaning in a conventional washing machine.
- a method is provided which includes the steps of directing a spray hose nozzle generally at a soiled article, forming a precleaning solution having a controlled concentration of chemical product in water, directing a high pressure stream of solution from the nozzle to the article, and squeezing excess solution from the article.
- a chemical product dispenser which addresses this problem is provided which includes a container and base which together form a reservoir to house a chemical product.
- the base includes a water inlet and solution outlet, as well as a solution providing means which forms a solution of a controlled concentration of chemical product in water.
- the dispenser is capable of providing a plurality of discrete and predictable concentrations.
- concentrations can be controlled by varying the water pressure (or flow rate), water temperature, and the proportion of water diverted to a reservoir.
- the amount of water diverted can be controlled by hole size, baffling, metering tip, nozzle configuration or spray pattern methods.
- the hardness and solubility of the product, which can be controlled by formulation, may also affect use concentrations.
- the types of solid or cast chemical products that may be used in conjunction with the present invention include detergents, sanitizers, disinfectants, odor control substances, odor counteractant substances, cleaners, and foamers.
- FIGURE 1 is a perspective view showing a system constructed consistent with the principles of the present invention, used specifically in a sink rinsing operation;
- FIGURE 2A is an exploded perspective view of a portion of the apparatus depicted in Fig. 1;
- FIGURE 2B is a side cross-sectional view taken along line 2B-2B in Figure 2A, showing flow paths therein.
- FIGURE 3 is a graph showing the relationship between various water temperatures and dispensing rates based on metering tips used in the dispenser depicted in Fig. 2.
- the present invention depicts a clinic sink system including a system of products and dispensing equipment to address the odor and sanitation needs of health care facilities in dealing with soiled articles that are rinsed or precleaned at a utility sink, or clinic sink, station.
- soiled articles include diapers, hand towels, washcloths, personal linens, and general bed linens soiled with human waste products.
- the invention is particularly useful in facilities in which soiled articles may be transported to a conveniently-located utility room in the facility which has a cleaning station. Articles may be rinsed or precleaned in a clinic sink to remove gross solids using a preferred method of the invention. After flushing, the articles may be stored in sealed containers, for example, plastic bags, and transported to a conventional washing machine for final cleaning.
- the invention also preferably utilizes a dispensing mechanism wherein an odor controlling agent and/or other chemical products are put into solution with the rinse water at one or more controlled concentrations during the precleaning process.
- a high pressure trigger controlled nozzle may be used with the invention to improve soil removal efficiency.
- a clinic sink system is shown generally in Figure 1.
- This system includes a water source 23, a sink or basin 28, and a chemical product dispenser 10 connected to water source 23 and having a nozzle 26 located proximate sink 28.
- Process of Cleaning Soiled Articles a method is provided for precleaning soiled fabric or other articles. Such a method is particularly useful in facilities such as nursing homes, child care centers, and hospitals to provide improved precleaning and rinsing of gross waste product from soiled articles prior to washing the articles in conventional washing machines.
- the method may be used on articles made of natural or synthetic fabrics such as cotton, polyester, or blends thereof, as well as other materials and articles which can become soiled with gross waste product as are generally known in the art.
- a water source under pressure such as water source 23 is turned on.
- This water source 23 is connected to a spray hose with a spray nozzle, such as nozzle 26, with a chemical product dispenser connected therebetween to dispense chemical product into the water stream to form a solution.
- the pressure and temperature may also be adjusted for the water source at this time.
- a soiled article is first positioned over a clinic sink bowl such as sink 28 in Figure 1. The article may rest on a specialized platform or holder, may be held by hand, or may simply be placed in the basin.
- the spray hose having nozzle 26 is directed at the soiled article, and a trigger such as trigger 27 of nozzle 26 is then depressed to direct a high pressure precleaning solution of water and chemical product at the soiled article.
- This precleaning solution is preferably formed by the flow of water through a dispensing device such as device 10, discussed in greater detail below.
- the concentration of chemical product in the formed solution may be controlled without operator intervention. Rather, the solution is formed by simply spraying the article with the nozzle and inducing water flow through the dispensing device.
- the article is preferably sprayed until it is thoroughly precleaned, with substantially all of the loose waste removed and with the article substantially impregnated with the chemical product. It is believed that the spraying operation should take approximately thirty to sixty seconds for a single article.
- the next step is to squeeze the excess chemical product and water out of the article. This is generally performed by hand.
- a product which has been sprayed and wrung out may then be placed into a hopper or otherwise transported for general cleaning using a standard commercial washing machine. Residual product remains on the article, further controlling lingering odors.
- a chemical product is put into solution with water flowing between water source 23 and nozzle 26 using a dispensing device which is preferably capable of dispensing the product at a known flow rate.
- the formation of the precleaning solution does not require any additional steps by an operator, as the dispenser preferably forms the solution with the water flowing therethrough.
- the dispensing device 10 described below and shown in Figs. 1, 2A and 2B is one such mechanism for putting the chemical product into solution with the water flowing between the water source 23 and nozzle 26.
- Other methods for putting chemical product into solution with a stream of water between a water source and a nozzle are known within the art.
- Chemical products that can be placed into solution for dispensing through nozzle 26 include products that contain fragrances and odor control counteractants to control foul odors. Products might also include sanitizing agents such as quaternary ammonium compounds or other EPA registered sanitizers and disinfectants.
- the chemical product could also be formulated to contain detergent ingredients, such as builders, surfactants, and alkaline sources.
- the chemical product could include deodorizing agents that reduce or kill odor causing bacteria.
- these chemical products include a combination of some or all of the above- mentioned compositions and agents.
- the chemical product to be utilized would be in liquid, gel, slurry, powder, or solid block form, the latter mode being described above with respect to dispenser 10.
- composition of Table I is provided as only one working example of a composition suitable for use with the invention. Other compositions having other desired characteristics may be used in the alternative.
- Sozio 4719 Country Fresh Fragrance 25 . 000
- the concentration of chemical product in solution may be varied by adjusting the mix ratio of water and product. Preferred concentrations range from 500 to 5,000 ppm. These concentrations will deliver adequate odor control and cleaning characteristics. Adjustments to flow rates are dependent on the equipment selected.
- One device for accomplishing variation of the mix ratio is the dispenser 10 shown in Figs. 1, 2A and 2B. Other dispensers and devices to accomplish the mixing are also well known. However, it has been found that dispenser 10 is preferred as it enables the selection of a number of discrete, predicatable concentrations for any given chemical product, water pressure and water temperature. As discussed below, the concentration of chemical product output from dispenser 10 may be controlled relatively easily by selecting between a plurality of metering tips having different orifice dimensions to restrict the flow of water diverted into the reservoir.
- the concentration of chemical product may also be controlled by controlling the flow rate or pressure
- the method enables health care workers to preclean soiled articles with improved efficiency and sanitization. Gross waste product may be removed, and an article may be pretreated, by simply spraying a high pressure stream of preferred solution and squeezing out the excess solution therefrom. The precleaning solution is mixed to the desired concentration with little or no additional operator effort during precleaning. No rinsing step is required, although such a step may be performed if desired.
- the risk of transmitting disease from soiled articles to a worker is reduced. Consequently, a faster and safer precleaning may be accomplished using this method.
- the task described herein is significantly less burdensome to workers. Gross human waste product can be rather foul smelling, and the present method may make the cleaning of soiled articles much less offensive to those performing the task.
- the ease of learning and operating the cleaning system is also benefitted by the present method. Since a controlled mixture is provided through the nozzle, the solution flow rate and concentration preferably does not have to be carefully controlled by a worker. Consequently, an operator need not be concerned with learning how to control flow rates, so persons unfamiliar with the equipment may also be able to operate it efficiently.
- Cleanup of a work station is also much easier through the preferred method.
- the solution typically contains the necessary products for pretreating soiled articles
- the same products will usually be able to sanitize the work station to an acceptable condition simply by spraying the clinic sink or work station itself with the same nozzle. In most applications, no additional apparatus or products are necessary.
- Another advantage of the present method is that improved cleaning may be accomplished over using a conventional washing machine by itself or in conjunction with a conventional water rinsing step.
- odor control, disinfecting and sanitizing products By providing several types of odor control, disinfecting and sanitizing products, a soiled article will be sufficiently precleaned and impregnated with solution by the time it is finally washed in a conventional machine. It is believed that the articles will generally be cleaner by the addition of these precleaning steps. Further, as discussed above, the same benefits of odor control and sanitization are provided from the preferred method throughout the transport of the articles to a washing facility.
- the present invention is capable of providing improved sanitization and odor control in precleaning soiled articles in health care and other facilities, and making precleaning a much less offensive process than heretofore has been possible.
- Dispenser The present invention is also directed to a preferred solid chemical product dispenser for use in the clinic sink system, which is designated generally as 10 in Figure 1, and shown connected to a water source 23 proximate a sink or.basin 28.
- the dispenser includes a base 12 having a water inlet 14 and a solution outlet 16.
- Dispenser 10 has a container 18 operably connected to base 12 to form a reservoir to contain solid chemical product.
- Base 12 and container 18 are preferably molded of a chemical resistant plastic such as polyethylene. Other plastics, as well as metals, alloys thereof, or composite materials may be used.
- the dispenser also has an inlet connecting hose 20 for connecting water inlet 14 to a source of water 23 under pressure.
- nozzle connecting hose 24 for connecting the solution outlet to a nozzle 26.
- Hoses 20 and 24 may be of varying sizes and constructions known in the art. Preferably hoses 20 and 24 are 1/2" - 5/8" diameter hoses constructed of flexible chemical resistant tubing. Each hose is operatively connected to the dispenser 10 by a plastic or metal fitting.
- the base 12 has a ring shaped flange 1 at its lower edge 2 for connection to container 18, which together form a reservoir for the material to be dispensed.
- the container 18 will be connected in such a manner as to ensure easy disconnection, as for refilling, and providing leak-proof fit when connected to the flange 1.
- the container base 3 includes external threads 4 to receive internal threads 5 on the flange 1, at the bottom side 2 of base 12.
- the base 12 is molded to receive and hold an 0 ring 6 of rubber or like material, and ensures against the leakage of water between the container and the flange 1 when the container 18 is fastened to the flange 1.
- some form of retaining system is preferred. As shown in Fig. 2A, this may be accomplished by means of a concave screen or shield 7 placed between the base and the material so as to abut 0 ring 6.
- the mesh size of shield 7 is chosen so as to provide a rigid mechanical support for the cast solid detergent material, while permitting the free passage of water through the shield 7 and onto the cast detergent.
- the cast solid material may be biased away from the base by means of a pair of screens separated by one or more springs connected therebetween.
- one screen would rest against the base and the other would rest against the solid material, parallel to the first screen.
- Springs located therebetween would therefore be able to bias, or retain, the material away from the base.
- FIG. 2B the internal flow path 22 of the water as it passes through base 12 will be examined. Regardless of the pressure of the water supply, the majority of the water passes through inlet 14 along flow path 22 and passes directly through auxiliary flow path 52 and continues to outlet 16. Some of the water, however, is diverted through water intake path 8 and travels upwardly to metering tip 9.
- orifice 11 of metering tip 9 is chosen to provide the desired flow rate based upon the input water pressure appearing at inlet 14, the product being dispensed, and the preferred water temperature. Water flowing through orifice 11 impinges the base of the material (not shown) and causes it to erode, creating a solution, residing in region 13, which is composed of a desired concentration of water and cast solid detergent material. This solution flows from region 13 through product solution outlet orifice 40 which is part of metering tip 15. The product solution then flows downwardly through product solution path 17 and is entrained in the water flowing outwardly along path 52 and out of outlet 16. Control of the concentration of the chemical product in the solution may be provided by varying the water pressure (or flow rate), water temperature, and proportion of water diverted to the block of chemical product by the dispenser. The concentration is also dependent upon the hardness and solubility of the product.
- One convenient manner of controlling concentrations can be provided by using varying sizes of metering tips for one or both of tips 9 and 15. By varying the orifice size of either of these tips, the percentage of water diverted to the chemical product can be controlled. Consequently, it is preferable that these tips be threaded or otherwise quickly removable for easy exchange of tips. In some instances it may further be preferable to color code or otherwise label different sizes of metering tips, so that for different products or conditions, tips can be exchanged quickly and easily. Other manners of varying the percentage of water diverted may include baffling, different nozzle or spray patterns, fixed hole sizes (no exchangeable metering tips) , or other flow restricting devices known in the art. Referring to Fig.
- the orifice 11 of metering tip 9 may be sized to have a diameter of 0.04 mm, resulting in the dispensing rates shown in Fig. 3 for the composition shown in Table I at water temperatures of 65°F, 85°F and 110°F and at a water flow rate of 3.5 gal/min. Each cycle consisted of one minute on and 15 minutes off. In another embodiment, a higher dispensing rate can be obtained under the same conditions by choosing an outlet orifice 40 having a diameter of 0.128 mm, as seen in Fig. 3.
- the concentration, or rate of flow of product in solution is controllable, which is often a concern when dealing with caustic products. Further, this concentration is predictable, and can be selected from a plurality of discrete concentrations for a given product composition, water pressure (or flow rate), and water temperature by selecting a metering tip or otherwise restricting flow into the reservoir.
- the flow rate for the device may be easily varied for different products. In most cases, this may be accomplished simply by exchanging tips in the base. Therefore, a number of discrete concentration values can be quickly selected for any dispenser. Product is also easily exchangeable given the easy removal of the container from the base.
- the dispenser is also reliable, as no electrical power is required, and no moving parts are incorporated therein. It is believed that little maintenance would be required and installation would be relatively simple in most applications.
