Description

Continuous oxygen mask

The present invention relates to an oxygen supply mask, in particular, it is a continuous oxygen supply mask that can continue to supply oxygen without removing the mask body and avoid pressure damage.

1. Creative motivation:

Oxygen therapy is intended to provide a higher oxygen concentration than the atmospheric oxygen concentration (21%), which has been achieved to correct the patient's arterial oxygen partial pressure greater than 60% mmHg under hypoxic conditions, or the blood oxygen saturation concentration reaches More than 90% is the main indicator, and the purpose is to maintain the oxygen concentration in the patient's blood and reduce breathing work, to reduce or improve the patient's tissue hypoxia.

In clinic, due to the disease factors of patients, the oxygen therapy equipment provided is not the same. For patients with large sputum, dry sputum, and high oxygen demand, the oxygen mask (O2 mask) is usually provided in conjunction with a moist spray. Use the bottle to humidify phlegm and reduce the damage to the mucosa caused by excessive oxygen concentration. In the process of using the oxygen mask, because the mouth and nose are covered, the clinical patients need to remove the oxygen mask for technical operations before eating or doing any treatment such as sputum extraction or nasogastric tube care.

In addition, the patient's sputum is large due to the humidified sputum. Remove the oxygen mask and repeat the sputum extraction technique to maintain the patient's airway, which not only disturbs the patient, but also removes the mask and repeats the technical operation. The patient may In the face of a brief interruption in the supply of oxygen, the hidden crisis threatens the life safety of patients. It is even more worrying to consult the domestic hospitals for the standard of technical operation time after the mask is removed.

Feeling at the difficulties and difficulties faced by clinical oxygen masks, the motivation for inventing the present invention has verified that most of the relevant mask device parts focus on inventions related to the prevention of pressure damage, but there is no patent for the potential crisis brought by oxygen masks. In view of this, the present inventor has developed a multi-functional continuous oxygen supply uninterrupted oxygen mask with continuous oxygen supply, unobstructed operation technology, prevention of pressure damage, convenient eating, etc. This device has safety, functionality, and ease of operation And promotion, improve patient safety and prevent oxygen supply interruption, in order to maintain the safety of patients' lives.

2. Document verification and academic basis:

1. The role and function of oxygen mask in oxygen therapy:

Clinical oxygen mask (O2 mask) is one of the common oxygen therapy equipment groups, which can cover the nose and mouth for oxygen support. The common clinical method of providing oxygen is to use a nasal catheter (providing low-flow oxygen FiO2 24-44% straight through the nasal cavity), but if the patient breathes and breathes, there is more room oxygen air inhaled, and the FiO2 provided by the nasal catheter decreases, so it cannot To meet the patient's blood oxygen concentration, and replace it with a face mask, the entire mouth and nose mask can be used as a gas reservoir, which can provide higher FiO2 (40%-60%). In addition, the oxygen mask can be connected to an aerosol device. With the atomized water molecules in the wet bottle, when the patient inhales, the dry sputum is moistened to facilitate the coughing out of the sputum to maintain the airway and the sputum accumulation.

2. The structure and purpose of the oxygen mask:

(1) Structural surface of oxygen mask:

A face mask is an aerosol that is placed on a patient's nose, mouth or tracheal incision to supply oxygen or aerosol. The appearance of the oxygen mask is lengthened to cover the patient's mouth and nose. There are openings on both sides of the nose of the mask to exchange the discharged carbon dioxide with the atmosphere. The mask connector is connected to the aerosol delivered by the serpentine tube or the patient uses a micro spray cup The diameter is 22mm, which can be combined with no leakage. The elastic aluminum sheet is placed on the mask near the nasal cavity and adjusted according to the patient's nose curvature. It is closely attached to the patient and is not easy to fall.

(2) Oxygen mask material:

The mask material is made of medical-grade PVC compound, which reduces allergies and better compactness. The appearance of the mask contains aluminum sheets at the raised nose bridge. It is elastic and not easy to break. It can be adjusted to the patient's face with the nose curvature and is not easy to fall off. Use latex-free ingredients for the head straps. Length elastic straps pass through the small holes on both sides of the mask so that the patient can place the ear and fix it on the head of the patient. It is not easy to loosen and cause allergies.

3. Oxygen mask causes iatrogenic pressure damage:

According to 2016 (National Pressure Ulcer Advisory Panel, NPUAP), a pressure injury is redefined as "skin or soft tissue underneath the skin, which is usually located on the bone of the body or related to certain medical equipment. These injuries may appear to be skin Intact, or wounded, or may be painful. The cause of injury is strong or continuous compression, or accompanied by shear force, and these may be related to climate, nutrition, blood circulation, comorbidities, and soft tissue conditions "Oxygen mask is one of the medical equipment. It is placed on both sides of the ear and the head by an elastic band. Therefore, pressure is formed on the face, ear, and head. Common pressure injuries are not only at the bone process, All medical devices that can compress the skin and affect the blood circulation can cause pressure injuries.

If the mask is not fixed properly and generates shear force with the skin pulling, it is easy to form pressure damage on the thin skin above the ears and the bridge of the nose. Adding an oxygen mask can easily increase the moisture factor of the facial skin, which can increase the pressure damage. .

Based on the above, patients who use oxygen masks are those who need oxygen frequently. However, in clinical practice, patients who use face masks are prone to breed bacteria because their mouths and noses are in a humid and warm state for a long time, and oxygen masks are even needed for diseases related to the old and weak respiratory systems. Therefore, oral cleansing may be required multiple times a day, phlegm assistance may be required, or a nasogastric tube indwelling may also require care and inspection.

During this series of care, if the mask is removed rashly, it may cause hypoxia and endanger life. Traditionally, when performing oral cleaning and treatment, it is necessary to remove the mask to perform nursing measures. Therefore, when performing oral care treatment, the most feared is the interruption of oxygen supply and the occurrence of safety incidents that harm patients.

Therefore, the structure and function of conventional oxygen masks are still not ideal, and there is indeed a need for improvement.

It is because that the inventor has many years of practical experience in product design and development, as well as active and concentrated research and development thinking. Through countless actual tests and experiments, the present invention has been produced.

The purpose of the present invention is to provide a continuous oxygen supply mask that can continue to supply oxygen without removing the mask body and avoid pressure damage.

To achieve the above purpose, the present invention includes a mask body, a flip cover, and a dressing, wherein the surface of the mask body has an open portion and a connecting seat, the two sides of the mask body are connected by a fixing belt, and the mask body is under the mask body The side is provided with a through hole; the shape and setting position of the flip cover are matched with the open part; the upper side of the flip cover is movably arranged on the connecting seat; the dressing is arranged on the upper side of the mask body.

Using a flip cover that can be lifted or closed on the oxygen mask, when the patient eats or performs oral cleaning, related technical operations of the nose and mouth (such as sputum suction or nasogastric tube care, etc.), as long as the flip is lifted, no The mask body must be removed and the oxygen can be continuously supplied without interruption.

By contacting the face and nose bridge of the patient with the dressing, it can conform to human facial engineering and avoid pressure damage.

Compared with the traditional oxygen mask, the present invention has multiple functions such as safety, convenience, and comfort.
