Definitions

  • ABSTRACT This invention relates to a washing apparatus by which a washing medium is applied to a surface to be washed and removed from said surface by suction.
  • the invention is concerned with a special construction of the means for coupling a multi-channel hose to a source of washing medium under pressure and a source of vacuum at one end and to a nozzle head both for spreading the washing medium onto the surface and for removing used medium from the surface at the other end.
  • the apparatus is especially but not exclusively designed for washing the skin surface of bed ridden patients in a sick bed.
  • the washing apparatus comprises hose connecting members mounted on each end of a multi-channel hose with screw or bayonet coupling means and corresponding bayonet coupling sockets both on the nozzle head and on the source.
  • the invention also comprises different types of nozzle heads and other details of construction of the connecting and coupling means between the source, the multi-channel hose and the nozzle heads and of valve means for shutting off the flow of pressure medium through the hose.
  • FIGS WASHING APPARATUS This invention relates to a washing apparatus by which a washing medium is applied to a surface to be washed and removed from said surface, especially for wahing the skin of persons, particularly bedridden persons.
  • the object of the invention is to provide an apparatus which is simple of construction and in which a hose for the admission of washing medium and for evacuation of used washing medium has two or more channels with identical end connections for optional connection at one end with a source of washing medium under pressure and a source of vacuum for the evacuation of the used washing medium, and at the other end with a nozzle head for applying the washing medium to the surface to be washed and removing the same from said surface.
  • different nozzle heads can be used, e.g. for washing of the surface with more or less medium, in connection with the same source and the same hose.
  • Another object of the invention is to make it possible to connect any of the end connections of the hose either to the source or to the nozzle head, and to permit a rapid exchange of nozzle heads of different kinds.
  • the end connections of the hose further comprise means for the interruption of the flow of washing liquid-and/or pressurized air either optionally during the washing operation or automatically when disconnecting the hose connection from the nozzle head.
  • the invention does not comprise the known principle of washing surfaces by means of a nozzle head which leads washing liquid to the surface and removes the used washing liquid, but only the construction and combination of coupling elements which make the apparatus especially well adapted for the washing of patients in a sick bed, each element being easy to handle and to combine with others according to requirements.
  • the washing apparatus comprising the above stated elements is especially characterized in that it comprises hose connecting members to be mounted on each end of a multichannel hose and consisting of a tubular handle having screw or bayonet coupling means at its forward end and immediately inwards thereof a coupling member rotatably but axially unmovably mounted within said handle, connection sleeves on said coupling member projecting inwardly into the ends of the difierent channels of the multi-channel hose and outwardly projecting connection sleeves on said coupling member communicating with said inwardly projecting connection sleeves, bayonet coupling sockets both on the nozzle means and the source for connection with the corresponding screw or bayonet connecting means of the handle, said'sockets having openings adapted for receiving the outwardly projecting connection sleeves, said openings communicating respectively with the pressure and suction channels of the source or nozzle head connected thereto.
  • the rotation of the coupling portion and the hose connected therewith relative to the handle resulting from the connection or disconnection of the hose and the nozzle head by means of the bayonet coupling means can advantageously be used for actuating a valve member for shutting ofi the pressure channels in the hose by squeezing, thereby stopping the flow of washing liquid upon the removal of the nozzle head or upon the exchange of nozzle heads.
  • the same valve member can with simple means also be made operable from the outside so that the admission of washing liquid, when required, can be momentarily shut off during the washing operation, e.g., when passing from one limb to another.
  • a guiding element which surrounds the forward end of the hose engaging the inwardly projecting sleeves of the coupling member, and which is rotatably guided in the handle, said guiding element having a rotatable valve member which in an outwardly swung position enters a side opening in the handle and in an upwardly swung position squeezes the hose channel or hose channels leading the washing medium under pressure to the nozzle head.
  • FIG. 1 is an exploded view in axial section of a hose coupling according to a preferred embodiment of the invention.
  • FIG. 2' is an end view seen from line IIII in FIG. 1 of the coupling member forming part of the housing coupling.
  • FIG. 3 is an end view seen from line III-III in FIG. 1 of the guiding element forming part of the hose coupling.
  • FIG. 4 is a section along line IVIV in FIG. 1 through the handle forming part of the hose coupling.
  • FIG. 5 shows a cross section of the multi-channe hose.
  • FIG. 6 shows a longitudinal section through the assembled parts of the hose coupling.
  • FIG. 7 shows a longitudinal section along line VII- VII in FIG. 8 of a nozzle head for fine washing.
  • FIG. 8 is an end view of the nozzle head according to FIG. 7 seen from the hose connection end.
  • FIG. 9 shows a longitudinal section of a nozzle head for flushing.
  • the first figure of the reference numerals refers to the different main parts of the apparatus and the second figure to the details of said parts.
  • the hose coupling illustrated in FIG. 1 for the connection of the hose 10 includes a coupling member 20, a guiding element 30 and a handle 40.
  • the hose 10 has a relatively wide suction channel 11 and two narrower channels 13 for pressurized medium.
  • the coupling member consists mainly of a circular disc 21 with a peripheral groove 22 along its edge and supporting inwardly and outwardly projecting connecting sleeves communicating with each other by pairs and having their axes parallel with the axis of the disc, of which two smaller inwardly projecting connecting parts 23 are provided'for insertion into the smaller pressure channels 13 of the hose l0 and one wider inwardly projecting connecting sleeve 24 is provided 'for insertion into the wider suction channel 11 of the hose 10, the communicating outwardly directed connecting sleeves 25 and 26, respectively, being arranged to cooperate with corresponding openings in a connected coupling member in a manner to be described later on.
  • the disc 21 has furtherv two guiding holes 27 in diametrically opposed positions relative to the center of the plate for cooperation with guiding pins on the guiding element.
  • the guiding element 30 consists of a mainly cylindrical part 31 of approximately the same diameter as the disc 21 of the coupling member 20 and provided with an axial guide opening 32 of the same shape as the cross sectional contour of the multi-channel hose.
  • the guiding element 30 On its outer end turned towards the coupling member 20 the guiding element 30 has two guiding pins 33 to be inserted into the guiding holes 27 of the coupling member 20.
  • the guiding element 30 has on its one side a peripheral recess 34 extending along approximately onefourth of the outer periphery of the guiding element. On its opposite side the guiding element has on its inner end turned away from the coupling member an incision 35.
  • An abutment 36 forming the valve member is attached to the wall portion of the guidingjelement limited by the incision 35 by means of a thin web 37 which is flexible and forms a sort of hinge and simultaneously a spring between the guiding element and said abutment 36.
  • the handle 40 consists of a tubular member-41 and a sleeve-like portion forming an axial extension of the tubular member. At its uppermost end, as shown in FIG. 1, the handle has a screw or bayonet fitting 42 having inner projections 43 arranged along screw lines and arranged for cooperation with a screw or bayonet socket on the nozzle head to be described further on. From the bayonet fitting inwards, the handle has a little stepped-in portion 44 and immediately inwards thereof peripheral strips 45, a cylindrical wall 46 and near the handle portion inwardly projecting abutments 47 and 48.
  • the cylindrical wall 46 has on one side a U-shaped slot 46a forming a tongue 49 hinged at its upper end by the elasticity ofthe material of which the member 40 is formed.
  • FIG. 6 The parts described above with reference to FIGS. 1-5 are shown in their assembled state in FIG. 6 in which the hose 10 is shown inserted into the guiding element closely surrounding the same, the lower edge of said guiding element resting on the abutment 48 while the abutment 47 projects into the recess 34 of the guiding member.
  • the guiding member 30 thus is capable of limited rotation within the handle about an angle corresponding to the difference between the peripheral extent of the projecting abutment 47 and of the recess 34.
  • the end of the hose l projecting beyond the guiding element 30 has its smaller channels 13 pressed onto the inwardly projecting, smaller. connecting sleeves '23 and its larger suction channel 11 pressed onto the inwardly directed, larger connecting sleeve 24 of the coupling member 20.
  • the coupling member is inserted into the handle in such a manner that the peripheral groove 22 of the disc 21 snapes over the peripheral strips 45 on the cylindrical wall 46 and is thereby rotatably kept in a determined axial position as shown in FIG. 6.
  • the ends of the channels 11 and 13 of the hose are maintained in engagement with the preferably conical connection sleeves 23, 24 by. the opening 32 of the guiding element 30.
  • the pins 33 on the guiding element are inserted into the guidingholes 27 of the coupling member 20.
  • the abutment 36 forming the valve member is then bent inwards about the web 37 and maintained by the resiliency of the web against the tongue 49 of the handle which thereby is bent slightly outwards.
  • the nozzle head 50 comprises a screw or bayonet socket 51 of such form that it can be screwed into the screw or bayonet fitting 42, 43 in the handle 40.
  • This bayonet fitting is-traversed by three axial channels 52, 53 arranged to correspond to the outwardly directed connection sleeves 25, 26 on the coupling member 20 and dimensioned for tight fitting onto the outside of said sleeves.
  • the larger one 53 communicates directly with the inside of a spoon-shaped casing 54, the open side of which lies in a plane and with the exception of a marginal slit is covered by a plane cover plate 55.
  • this plate On its'side facing the inside of the casing 54 this plate has a longitudinal channel 56 which has a connection sleeve 57 engaging the outside of a nozzle 58 whichby small channels 59 communicates with both openings 52 in the socket 51.
  • a connection sleeve 57 engaging the outside of a nozzle 58 whichby small channels 59 communicates with both openings 52 in the socket 51.
  • An insert of porous material is preferably placed within the connection sleeve 57.
  • the coupling member 20 and the guiding element 30 must be in a rotational position relative to the handle 40, in which the abutment 36 keeps the pressure channels 13 squeezed by the abutment of its outside against the inside of the cylindrical wall 46 of the handle. In this position the nozzle head 50 is placed with its socket openings 52, 53 over the connection sleeves 25 and 26, respectively, of the coupling member 20.
  • connection sleeves By screwing the socket 51 into the bayonet fitting 42 the connection sleeves are pressed into their respective socket openings simultaneously as the coupling member 20 and the guiding element 30, the latter by the mutual engagement of the guiding holes 27 and the guiding pins 33, are turned until the abutment 36 is positioned inside the tongue 49 and thereby permits the releasing of the pressure channels 13 of the hose.
  • These pressure channels through which washing liquid and pressurized air are admitted, lead these media through the small channels 59 into the nozzle 58 where they are mixed to foam in the porous insert. The washingfoam then flows from the channel 56 to the outside of the plate 55.
  • the disconnection is performed by screwing the bayonet socket 51 out of the bayonet fitting 42 whereby the coupling member 20 and the guiding element 30 are turned so that the abutment 36 is kept in the pressed-in position by the inner cylindrical wall 46, thus keeping the pressure channels shut.
  • the same coupling means can be used for nozzle heads in which only one of the media admitted through the channels 13 is to be used.
  • An example of such a nozzle means is illustrated in FIG. 9 and indicated by the general reference numeral 60.
  • This nozzle head has a screw or bayonet socket 61 of the same type as the socket 51 shown in FIGS. 7 and 8. It is connected with the coupling member for the hose in the same manner as described above.
  • the socket 61 proper which in end view has a form similar to that shown in FIG. 8, has a larger connecting opening 62 and two smaller connecting openings 63 of which one isa blind hole so that the medium admitted through one of the pressure channels 13 of the hose is not used.
  • the socket is made in one piece with a tubular casing 64 on the forward end of which a suction nozzle 65 is mounted which is chamfered on one side and the suction opening 66 of which is surrounded by a cap 67.
  • the other one of the connecting openings 63 i.e., the one which is not a blind hole, communicates with a chamber 68 with a valve 69 which can be opened from the outside against spring action.
  • the outlet of the valve communicates with a tube 70 connecting the socket 61 with a channel 71 in the suction nozzle 65 and ending in a small spray nozzle 72 on the outside of the suction nozzle 65.
  • the suction nozzle communicates with the inside of the casing 64 by a connection sleeve 73, on the inner end of which is mounted a filter bag 74 by means of a clamping ring 75.
  • the nozzle head illustrated in FIG. 9 is principally intended for flushing and is used in the following manner.
  • the spray nozzle 72 is pointed at the body surface to be subjected to flushing.
  • the valve 69 is then opened by depressing it with a finger and the washing liquid is spread through the nozzle 72 onto the surface.
  • the cap 67 is moved over the sprayed surface and the washing liquid together with the loosened dirt is sucked in by the suction nozzle 66.
