Description

TECHNICAL FIELD The present disclosure generally relates to patient interfaces and respiratory systems for providing breathable gases flow to a patient. More particularly, the present disclosure relates to respiratory support accessories and/or components with one or more sensors on or near the patient interface. BACKGROUND Assisted breathing systems are available to aid patients in breathing for a number of reasons, for example due to, or in recovery from, a medical condition, during or following a medical procedure or otherwise for individuals who require a form of breathing support. In assisted breathing, respiratory gases are supplied to a patient through a flexible breathing tube. The gases expired by the patient may be channelled through a similar breathing tube or expelled to the patient's surroundings. The gases are, typically, administered to the patient through a patient interface, which may also comprise a short length of dedicated breathing tube to couple the interface with the supply tube. The patient interface may receive breathing gas from the flexible breathing tube and distribute it to the patient. Examples of a patient interface include a nasal cannula, nasal mask, oronasal or full face mask, and endotracheal (ET) tube. When providing respiratory support to a patient, it can be beneficial to monitor one or more patient and/or respiratory support system parameters during the therapy. Parameter monitoring may detect interruptions to therapy or changes in patient condition requiring clinical intervention. In order to measure patient and/or system parameters, one or more sensors are used. These parameters can be used individually or in conjunction with further parameters in assessing the patient's health. It would be desirable to provide an improved system, device or apparatus that overcomes or ameliorates one or more problem associated with the prior art or which provides a useful choice. SUMMARY According to an aspect of the present disclosure there is provided a fixation structure for securing a patient interface to a patient, the fixation structure comprising: a body having a first side and a second side, in use the first side of the body facing towards the patient and the second side of the body facing away from the patient, wherein the first side of the body is removably attachable to the patient; a fixing element on the second side of the body, the fixing element is removably attachable to the patient interface; and sensor componentry provided on or in one or both of the body and the fixing element or attachable to one or both of the body and the fixing element. According to an aspect of the present disclosure there is provided a fixation structure for securing a patient interface to a patient, the fixation structure comprising: a body having a first side and a second side; a patient attachment on the first side of the body; a fixing element on the second side of the body; and sensor componentry provided on or in any one or more of the body, the patient attachment and the fixing element or attachable to one or more of the body, the patient attachment and the fixing element. As used herein, the term sensor componentry is used to describe a component or components that include at least one sensor. The sensor componentry may also include any further elements required to perform its function. For example, the sensor componentry may comprise any one or more of a printed circuit board (PCB), a wireless module, a substrate, an antenna and/or a power source. In use, the first side of the body may face towards the patient, and the second side of the body may face towards the patient interface and/or away from the patient. The first side of the body may be removably attachable to the patient via the patient attachment. The fixation structure may secure the patient interface to the patient's skin. The fixation structure may be configured to secure the patient interface to the patient. The first side of the body may be removably attachable to the patient's skin via the patient attachment. The fixation structure may be configured to secure the patient interface to the patient's face. A fixation structure may also be referred to as an adhesive patch, dermal patch or securement apparatus. Any of these terms may be used interchangeably herein. In some configurations, the body comprises a substrate. The substrate may comprise a substrate material. The substrate may be a single layer or may have a plurality of layers. Each layer of the substrate may comprise the same material or a different material. In some configurations, the sensor componentry is at least partially flexible. The sensor componentry may comprise a printed circuit board (PCB). The PCB may be flexible. The PCB may be at least partly flexible. The PCB may be provided on a polyurethane material base. The PCB may comprise a printed conductive ink. The PCB may be printed on the first side and/or second side of the body. In some configurations
