Aspects of the present disclosure relate to an oxygen tubing affixing device.
Some people with breathing disorders can't get enough oxygen naturally. They may need supplemental oxygen, or oxygen therapy. People who receive oxygen therapy often see improved energy levels and sleep, and better quality of life.
To determine whether a person will benefit from oxygen therapy, doctors test the amount of oxygen in their arterial blood. Another way to check is using a pulse oximeter that indirectly measures oxygen levels, or saturation, without requiring a blood sample. The pulse oximeter clips onto a person's body part, like a finger. Low levels mean that a person may be a good candidate for supplemental oxygen.
Normal levels of arterial blood oxygen are between 75 and 100 mmHg (millimeters of mercury). An oxygen level of 60 mmHg or lower indicates the need for supplemental oxygen.
The present disclosure provides a device, system, and method for an oxygen tubing affixing device. In some embodiments, the device includes a flexible ear cuff configured to receive an oxygen tube, wherein the ear cuff is shaped to nestle between a pinna of an ear and a head of a patient; and a proximity sensor configured to fit around the oxygen tube and issue an alert when a distance between the head of the patient and the proximity sensor breaches a threshold.
In some embodiments, the system includes a flexible ear cuff configured to receive an oxygen tube, wherein the ear cuff is shaped to nestle between a pinna of an ear and a head of a patient.
In some embodiments, the method includes attaching a flexible ear cuff over an oxygen tube, wherein the ear cuff nestled between a pinna of an ear and a head of a patient.
Aspects of the present disclosure relate an oxygen tubing affixing device. While the present disclosure is not necessarily limited to such applications, various aspects of the disclosure may be appreciated through a discussion of various examples using this context.
Patients who rely on oxygen may struggle with keeping their oxygen tubes secure in their noses. Due to the oxygen tubing cylinder shape, with movement, the tube has a tendency to slip off of the patient's ear which pulls the oxygen nose piece either out of their nose or distorts it in a way that prevents them from receiving the necessary level of oxygen they need. There isn't a system in place to let doctors or nurses know when oxygen levels are low due to equipment malfunction. Because of this, patients who are unable to help themselves when a problem arises might be at risk for dangerously low oxygen levels and create a healthcare professional. As the technology evolves, the need to monitor pulse oximeter saturation is increasingly vital.
Therefore, in some embodiments, a device and a system are proposed to securely affix a patient's oxygen tubing in place, monitor blood oxygen levels, and/or alert healthcare staff when the tubing slips away from the face.
In some embodiments, an ear attachment device combines an earlobe oximeter clamp housing and over-the-ear-cuff protector to securely attach oxygen tubes to a patient's head. This design combines the oxygen tube and oximeter into a single device. In some embodiments, an attached sensors alerts doctors and nurses when a patient's tube has slipped out of place. This device improves efficiency of hospital staffing, and ultimately improves patient care.
Oxygen and Pulse Oximeters are in high demand due to the value associated with their use inpatient recovery in hospitals, hospice, and post-hospital care. However, the use of oxygen tubes and pulse oximeters can create issues. Oxygen tubes and pulse oximeters may often come detached and/or create irritation around a patient's head. In some embodiments, the proposed ear attachment device secures the oxygen tubing and pulse oximeter to a patient's head with an attachment sensor that gives an alert when the oxygen tubing becomes detached.
In some embodiments, device 200 is a flexible piece designed to securely fasten behind a patient's ear. In some embodiments, the device is hollow, allowing for a patient's oxygen tubing cylinder 290 to be fed through ear cuff 205. The ear cuff 205 is designed to conform to the shape of the ear, and acts as a casing to ensure the patient's oxygen tubing cylinder does not slip from their face. In addition to keeping the oxygen tubing cylinder 290 in place on the patient's face, device 200 is equipped with sensor(s) 260 at or near second end 210 to detect if the oxygen tubing cylinder 290 has been displaced.
In some embodiments, the ear cuff 205 is constructed of medical-grade silicone rubber (or a like material), which is flexible and durable. Silicone has a high coefficient of friction and inherent surface tack, which increases the friction of the tubing 290 and reduces the possibility of slippage.
At the base of the ear cuff 205 near end 220 is a wireless pulse oximeter earlobe clamp 230 (referred to as the pulse oximeter) which, when affixed to a patient's earlobe, monitors blood oxygen levels. Additionally, the pulse oximeter 230 aids in further securing the oxygen tubing cylinder 290 to the patient. In some embodiments, the pulse oximeter 230 may include wireless (e.g., Bluetooth) connectivity to provide flexibility in alerting capabilities.
Device 200 monitors the status of a patient's oxygen tubing cylinder 290 and collects a patient's blood oxygen vitals. In some embodiments, sensor 260 may detect if the oxygen tubing cylinder has slipped out of place, while pulse oximeter 230 monitors blood oxygen vitals. In some embodiments, if an abnormality occurs—due, for example, to a tubing 290 slip or a drop in blood oxygen levels—the device 200 issues an alert.
In some embodiments, in a healthcare facility setting, the device 200 can connect to the facility's central nursing station and the patient's bedside monitor via a wireless technique (e.g., Bluetooth). In some embodiments, the device 200 can also be connected to a patient's hospital wristband to be paired with the patient's assigned hospital code. In some embodiments, device 200 can connect to a mobile app of a designated caregiver. For example, device 200 may connect to a mobile device being monitored by a patient's health care professional.
In some embodiments, the device issues an alert to care staff through the paired devices (e.g., central station, bedside monitor, etc.) if a patient's conditions and vitals become dangerous. In some embodiments, because of changing goals in pulse oxygen saturation (e.g., the measurement for the amount of oxygen in a patients blood) for patients, the threshold of “dangerous” is pre-determined by users (e.g., medical professionals) during device configuration and may be adjusted by users in an administrative setting on a patient-by-patient basis. To prevent false alarms, the device may have a delay (e.g., 60 seconds) before registering anomalous events as dangerous and worthy of an alert. In some embodiments, this 60-second wait time is the device default, but can be overridden by the user during device configuration or any time during the device's lifetime. In some embodiments, thresholds can also be defined on a patient-by-patient basis.
In some embodiments, device 200 can be scanned with a registration mark (such as a bar code, not depicted) and tied to the patient's hospital wristband and electronic health records. In some embodiments, an individual patient profile may be linked to device 200 and may be used by care staff. In some embodiments, the profile helps provide context to doctors in an ever-changing hospital setting. The profile may also aid in patient hand-off while moving from a hospital to hospice care, or from a hospital to at-home care. For example, if John moves from a hospital into hospice care, his profile may be used at any facility he is transferred to providing additional data to his new healthcare staff so they can personalize his care experience.
In some embodiments, the device can further support patients' aftercare in hospice facilities, at home, and even with virtual nurses through telemedicine. In some embodiments, device 200 may support caretakers and alerts them when a patient reaches low oxygen levels and can document trends to inform decisions made by caretakers.
In some embodiments, when a patient's ear cuff is removed or replaced in a hospital setting, its replacement is re-paired with the associated devices via a wireless connection by a healthcare practitioner and paired with the patient's associated hospital code (e.g., with the patient's hospital wristband) and electronic health records.
In some embodiments, if device 200 is removed or replaced in an at-home setting, the paired mobile application allows a caregiver to note a device swap, so no abnormalities are recorded during the time of the swap. For example, a replacement device is re-paired with the app and the patient's profile via wireless connection.
In some embodiments, device 200 is able to connect to a healthcare facility's central station to alert staff to issues related to a patient's blood oxygen. Additionally, in some embodiments, device 200 can be connected to a mobile or desktop application with the option to connect with a patient's electronic health records to track and record patient vitals and blood oxygen levels. Beyond the hospital, the device can further support patients' aftercare in hospice facilities or at home.
In some embodiments, attachment sensor 460B has two parts to be closed around an oxygen tube. In some embodiments, the parts of attachment sensor 460B are connected with hinge 480. In some embodiments, the attachment sensors 460A and/or 460B have a wireless connection component 474 (e.g., Bluetooth), a proximity sensor 472, and a micro controller 476. In some embodiments, attachment sensors 460A and/or 460B comprise a medical-grade polymer body (e.g., polypropylene) encased in medical-grade silicone rubber. In some embodiments, wireless connection component 474 (e.g., Bluetooth) and proximity sensor 472 are connected to micro controller 476. In some embodiments, a proximity sensor is a sensor configured to detect the presence of a human in close proximity without any physical contact. Some examples of sensors that may be used include capacitive, capacitive displacement sensor, optical, photoelectric, photocell (reflective), laser rangefinder, passive (such as charge-coupled devices), passive thermal infrared, radar, reflection of ionizing radiation, sonar (e.g., active or passive), ultrasonic sensor, fiber optics sensor, and hall effect sensor.
Method 500 begins with operation 505 where a flexible ear cuff configured to receive an oxygen tube is attached to a patient. In some embodiments, the ear cuff is shaped to nestle between a pinna of an ear and a head of a patient. In some instances, the anatomy of the external ear is known as the auricle or pinna and includes the earlobe. In some embodiments, the flexible ear cuff is a tube with an inner diameter that is larger than the outer diameter of the oxygen tubing. For example, the flexible ear cuff may be sized so it can be slid over an oxygen tube.
Method 500 continues with operation 510 where a pulse oximeter is attached, with an earlobe clamp, at a first end of the flexible ear cuff, to an earlobe of the patient. In some embodiments, the flexible ear cuff may comprise a sleeve that a pulse oximeter may fit into. For example, a silicone flexible ear cuff may have a sleeve that a commercially available pulse oximeter may fit into.
At operation 520, a proximity sensor is attached to the oxygen tube. In some embodiments, the proximity sensor may be attached to the flexible ear cuff (as in
In operation 530 the oxygen tube is secured to the patient in such a manner that the proximity sensor is within a threshold proximity to the patient's skin. In some embodiments, the proximity sensor may continually or intermittently determine if it is within a proximity of the patient's skin. For example, the proximity sensor may include an infrared sensor, and the reading on the infrared sensor falling below a threshold may indicate that the sensor has moved away from the skin of the patient. In some embodiments, upon a determination that the proximity sensor is not within range of the skin, the system may send an alert to a caregiver.
