DETAILED DESCRIPTION OF THE INVENTION
(18) In this specification, the terms medical circuit and breathing circuit are used to indicate the general field of the invention. It is to be understood that a circuit is intended to include open circuits, which do not form a complete closed circuit. For example, CPAP systems typically consist of a single inspiratory breathing tube between the blower and the patient interface. The term breathing circuit is intended to include such open circuits. Similarly, the term medical circuit is intended to include both breathing circuits and insufflation circuits, which are also typically open. Similarly, the term medical tubing is intended to be read as flexible tubing suitable for use in the type of medical circuits described above connecting between components of a medical circuit and providing a low resistance gases pathway between components of a medical circuit.
(19) In the field of medical circuits, and in particular breathing circuits, including anaesthetic circuits, condensation or rain-out can be a particular problem where high humidity breathing gases come into contact with the walls of a component at a relatively lower temperature. With reference to
(20) It should be understood that delivery systems could also be continuous, variable or bi-level positive airway pressure or numerous other forms of respiratory therapy. The inspiratory tube 103 is connected to the outlet 104 of a humidification chamber 105 which contains a volume of water 106. The inspiratory tube 103 may include a heater or heater wires (not shown) which heat the humidified gases within the tube to reduce the formation of condensation. The humidification chamber 105 is heated by a heater plate 107 of humidifier base 108. The humidifier 108 is provided with an electronic controller which may comprise a microprocessor based controller executing computer software commands stored in associated memory.
(21) In response to the user set humidity or temperature value input via dial 110, for example, and/or other inputs, the controller determines when (or to what level) to energise heater plate 107 to heat the water 106 within the humidification chamber 105. As the volume of water is heated, water vapour begins to fill the chamber above the water's surface and is passed out of the humidification chamber outlet 104. A flow of gases (for example, air) is provided from a gases supply or ventilator 115, which enters the chamber 105 through inlet 116. Exhaled gases from the patient's mouth are returned to the ventilator via a return expiratory breathing tube 130 that may also include a heater or heater wires (not shown), which heat the humidified gases within the expiratory breathing tube to reduce the formation of condensation.
(22) It is preferable that medical tubing (for example the inspiratory and/or expiratory breathing tubes 103,130) is: resistant to crushing, resistant to restrictions in flow when bent (e.g., increased resistance to flow <50% when bent around a 1 inch cylinder), resistant to kinking, resistant to changes in length/volume under fluctuating internal pressure (e.g., resistance to compliance), resistant to leaking (e.g., <25 ml/min @6 kPa), have low flow resistance (e.g., increase in pressure @ max. rated flow <0.2 kPa), electrically safe (e.g., resistant to sparks in the tubing) given an operating environment that may be oxygen-rich.
(23) International standard ISO 5367:2000(E) (Fourth edition, 2000 Jun. 1) is one example of how some of these desirable parameters are measured and quantified, and the document is hereby incorporated into this specification in its entirety by reference. It is preferable that components described herein meet or exceed some or all of these standards. Further, reference to medical tubes includes breathing tubes as defined in the above ISO standard.
(24) In accordance with certain features, aspects and advantages of this invention, a component 1 is provided as an accessory for use with medical tubing. The components has particular application for the positioning and support of such medical tubing relative to a user or equipment associated with the user (e.g., user interfaces or patient interfaces, such as masks, nasal cannula and the like, briefly described above).
(25) The ability to locate a medical tube relative to a user has certain advantages. Being able to help support the weight of the medical tubing connected to equipment associated with the user has a number of advantages including but not limited to, for example, reducing the weight transferred to a user or equipment associated with the user, which may in turn impact on the efficiency of a treatment being provided to a user, or the overall comfort experienced by a user when using such equipment.
(26) Further, as a user moves or re-positions their body relative to the medical tubing or associated equipment, strain may be transferred to the tubing or to the user via the associated equipment. A relatively quick and effective re-positioning or re-locating of the tubing to provide support again would be useful. Certain features, aspects and advantages of the present invention attempt to provide or go at least some way towards providing at least an alternative component facilitating such advantages.
(27) Such a component can be utilised to position or locate inspiratory or expiratory medical tubing, or other tubing associated with such medical circuits as described above. Particular application may have uses in the OSA fields, as well as in hospital situations.
(28) According to the one aspect of the present invention, a component 1 is provided for use with a tube. The component 1 comprises a body 2 engageable with one or more external surface recesses 3 (or surface relief portions or sections) of a tube (e.g., such as those of a corrugated tube or tube with a helically recessed surface region). The component 1 includes a pair of jaws 4 that extend from the body 2. The jaws 4 can be used for attaching to or for gripping of an item (not shown). In use, in a first orientation 5 of the body 2 relative to the tube recesses 3, the component 1 is movable along a length of the tube. While in a second orientation 6 of the body 2 relative to the tube recesses 3, the component 1 is resistive to movement along a length of the tube.
(29) In a further aspect, the component 1 provides for use with one or more tubes (not shown). The component 1 comprises a body 2 engageable with one or more external surface recesses 3 (or surface relief portions or sections) of respective one or more tubes. The one or more tubes (not shown) are receivable by the body 2, with the body 2 being engageable with the external recesses of such tubes. The component 1 includes a pair of jaws 4 extending from the body 2 for gripping an item (not shown). In use, in a first orientation 5 of the body 2 relative to the respective tube(s) recesses (e.g. corrugations of a tube or tubes), the component 1 is movable along a length of the tube(s), and in a second orientation 6 of the body relative to the respective tube(s) recesses, the component 1 is resistive to movement along a length of the tube(s).
(30) In respect of the above, it will be seen that
(31) Advantageously, in the first orientation 5, the component 1 is oriented in a plane such that the body 2 is engageable with certain external recesses 3 of the tube when substantially co-axial with the tube. And, in the second orientation 6, the component 1 is oriented in a plane such that the body 2 is engageable with certain other external recesses 3 of the tube when substantially non co-axial with the tube. It will be appreciated, where for example the body 2 is configured for receiving two or more respective tubes, the component 1 is adapted to operate in the same manner.
(32) Surface recesses 3 can include surface relief features, such as repeating recesses 3 or other surface relief features such as those of a corrugated tube, or a tube having a helical outer rib extending along the length of the tube being held or engaged therewith by body 2.
(33)
(34) The body 2 substantially surrounds the perimeter, or circumference, of the tube(s), such that a portion or portions (such as projection 7 or 20, 22 or 30) of the body 2 are engageable with the surface recesses 3 or with surface relief portions or sections. Accordingly, the component 1 is enabled to be moved along the tube when in a first body orientation, yet the component 1 being resistive to being moved along the tube when in a second body orientation relative to the tube's recesses 3 or surface relief features.
(35) As a part of substantially surrounding the tube, an internal surface (or surfaces or portions of the internal surface) of the body 2 is or are engageable with the one or more external surface recesses 3 (or relief features) of the tube. In this manner, the body 2 may be substantially annular about the exterior surface of the tube being engaged.
(36) Turning to the jaws 4 of the component 1, in one preferred embodiment the jaws 4 are configured to be opposing upon one another, or co-acting on each other, when in their closed position 8. Such jaws 4, or other variations of these, may be configured such that they are hingedly biased toward each other in reaching a substantially closed position 8. Further, the jaws 4 can be openable from a substantially closed position 8 to enable the jaws 4 to receive and then close upon an item for gripping of that item. The jaws 4 can be openable by deflecting the jaws 4 away from each other. Manually actuating the jaws 4 to create such a deflection or opening is additionally facilitated by providing finger grips or tabs for the user of the component 1.
(37)
(38) In a similar manner,
(39) The jaws 4 are openable and can receive and then close to grip an item enabling a more secure option for locating of the tube that is engaged by the component 1.
(40) It will be appreciated this one or more feature, aspect or advantage of the invention provides for the re-positioning of the component 1 onto different items or objects, as and where a user desires most useful for comfort or other reasons.
(41) Further, the component 1 allows the tube (and any attachments connected with the tube) to be re-positioned by moving of the tube when the component 1 is moved into the first body orientation that allows the component 1 to be moved along the tube (and about or from surface recess to recess or relief feature to feature) from a first set position to a second set position. When such a second set position is reached, the user re-orientates the component 1 such that the second body orientation is achieved to then prevent movement between the tube and component 1 (or at least to substantially resist movement between these).
(42) In one form, the portions of the body 2 engageable with the recesses 3 (or other surface relief features) are fixed or static portions of the body 2 (i.e. are not moveable). See for example the annular rib or lip portion 30 of
(43) Various items or objects that the component 1 may be attached to (i.e. grip) includes one or more of the following: clothing, bedding, structures associated with personal clothing (e.g. personal lanyard, belt) or bedding (e.g. bed frame, mattress), structures associated with medical equipment or where a user is located (e.g. stands, bed side table), including incubators, and cots. It will be appreciated other items or objects can be used to attaching the component 1 to via the gripping jaws 4. Accordingly, when the component 1 is in the second orientation 6 and the jaws 4 are gripping of an item, the component 1 acts to locate the tube in a set position.
(44) In other embodiments, a carer (e.g. mother, father or nurse) may hold a child or infant in a kangaroo style hold, and in such an instance the carer may attach the clip to their clothing such that tubing is supported without placing weight onto the patient interface and on to the child/infant.
(45) As mentioned above, the body 2 can include a shoulder portion 10 (or finger tab portion) associated with each jaw of the pair of jaws 4. Such a shoulder portion 10 assists in providing a surface for actuation, by a user, of the jaws 4 to an open position 9. Such shoulder portion 10 can, for example, be an enlarged region of the body 2.
(46) In use, shoulder portion 10 of the body 2 may be deflectable towards each other, such that, deflection moves the jaws 4 from a closed or substantially closed position 8 toward or to an open position 9. In return, release of the deflection provided by a user allows the hingedly biased jaws 4 to move back to a closed or substantially closed position 8. Advantageously, the shoulder portion 10 can be sized for relative ease of actuation by the fingers of a user, i.e. being finger tabs.
(47) In respect of the jaws 4 of the component 1, one or each jaw can include a grip or grips for gripping (e.g. frictionally) of an item or object. In one form, the grips are one or a series of ridges, projections or teeth 11. Such jaw grips are preferably interlocking or inter-lockable (or interposing) with one or more corresponding grips of an opposing or other jaw.
(48) In another embodiment, one of more of the grips can be shaped so as to expose one (or a series) of acute angled portions that face inwardly toward the body. Such acutely shaped portions may assist in helping to grip or grab the textile of a cloth (e.g. clothing or bedding sheets). This may for example be facilitated by the acute angled portions penetrating or semi-penetrating the weave of the cloth or fabric to which the grips are attached or becoming embedded into.
(49) In yet a further embodiment, although it should be recognised such a feature may be provided in combination with the acutely shaped portions discussed above, one of more of the grips may be shaped so as to expose one (or a series of) obtusely angled portions facing outwardly away from the body. In such a configuration, advantageously the grips allow the ease of insertion of cloth or material into the mouth of the jaws, and therefore allowing the grips (when released from their open position) to engage with the cloth or material (or object). When provided in combination with the acutely shaped portions, sets of grips may be provided that allow the relative ease of insertion of material into the mouth of the jaws, yet the ability to easily remove the material from the grips is reduced by the improved gripping capability of the acutely shaped portions.
(50) Such a component 1 may be formed of any suitable material allowing the above described features and deflection characteristics. It may be preferred that such a component 1 is however provided of a suitable, although not necessarily, medical grade material and, may for example, be of a suitable polymeric material.
(51) In a further form, in the first orientation 5, the internal surface of the body 2 may comprise at least one first projection 20 engageable with a corresponding first recess of the tube or of a first respective tube, and at least one second projection 22 engageable with the same or another recess located near the first recess in which the at least one first projection 20 is engageable. And, in the second orientation 6, the internal surface of the body 2 may comprise at least one first 20 and at least one second projection(s) 22 that are engaged or engageable with a recess or recesses 3 (or other repeating surface relief features) of the tube, or respective tubes, such recesses separated from one another by a distance along the length of the or each respective tube.
(52) When in the second orientation 6, this further form provides for the at least one first and at least one second projections 22 to act on the tube, or its recesses 3 or a part thereof (or surface relief features), to restrain (or resist) the component 1 from being moved between recesses 3 (or surface relief features) or along a length of the tube.
(53) As illustrated by
(54) As shown by
(55) As shown by
(56) In yet a further form, the component's body 2 can comprise of at least one lip for engaging with at least one recess of the tube, for example as illustrated by
(57) As shown by
(58) The component 1 shown by
(59) In such a first orientation, the internal surface of the body comprises, for each of the respective one or more tubes being engaged by the body, at least one first projection 7, 20, 50 engageable with a corresponding first recess of a respective tube, and at least one second projection 7, 22, 51 engageable with the same or another recess, of the same respective tube, located near the first recess in which the at least one first projection is engageable. Likewise, a further set of at least one first projections 7, 20, 60 and a further set of at least one second projection 7, 22, 61 is provided for engaging with a second tube. It will be understood that the body 2 may be adapted or shaped to receive and engage with one, two or more than two tubes.
(60) In a second orientation, the internal surface of the body 2 comprises, for each of the respective one or more tubes that the body may be engageable with, at least one first 7, 20 projection(s) and at least one second projection(s) 7, 22 engaged with a recess or recesses of each respective tube, wherein the engaged recesses of each respective tube are separated from one another by a distance along the length of each of the respective tube(s). The first and second projections 50, 51 are used in relation to engaging of a first tube, while first and second further projections 60, 61 are used in relation to engaging of a second tube.
(61) It will be appreciated the body 2 may be configured to engaged with additional tubes, such additional tubes would be engaged by further sets of first and second projections provided by an appropriately shaped body 2. For example,
(62)
(63) In addition, it will be appreciated the various embodiments described above, and as illustrated, may include a retainer portion for retaining an accessory, for example an accessory that may be associated with the tube, such as an electrical cable or sensor cable (e.g. a temperature probe cable). The retainer portion may even be configured for receiving a lanyard such as those that may be looped about a user's neck for further supporting the weight held by the clip and grips when gripping an item. However, preferred forms for the retainer 40 include those where a cable may be friction fitted into the retainer portion or region. Such a retainer may be shaped to receive and hold cable in in-situ, such as a temperature probe cable that may be associated with a controller or control system for a heated or electrically powered medical breathing tube.
(64) As shown in the embodiments of
(65) The foregoing description of the invention includes preferred forms thereof. Modifications may be made thereto without departing from the scope of the invention.
