Description

Pressure sore prevention oxygen mask for acute heart failure patients in cardiology department

Technical Field

The invention relates to the technical field of medical instruments, in particular to a pressure sore prevention oxygen mask for acute heart failure patients in cardiology.

Background

Heart failure, heart failure for short, refers to a heart circulatory disturbance syndrome caused by insufficient discharge of venous return blood volume from the heart due to the failure of the systolic and/or diastolic functions of the heart, resulting in venous system blood stasis and arterial system blood perfusion deficiency, which is manifested as pulmonary congestion and vena cava congestion.

Heart failure is not an independent disease, but the terminal stage of progression of heart disease, with the vast majority of heart failure beginning with left heart failure, i.e., first manifested as pulmonary circulation congestion.

Acute heart failure is manifested by fatigue, obviously reduced exercise endurance, and increased heart rate by 15-20 times/min, which in turn causes labored dyspnea and nocturnal paroxysmal dyspnea.

Once the diagnosis is confirmed, the patient needs regular treatment, and the initial treatment is oxygen inhalation through a mask or a nasal catheter; morphine, loop diuretics, cardiac tonics, and the like are administered intravenously; the patient can take the sitting position or the semi-lying position, the two legs are drooped, and the venous reflux of the lower limbs is reduced.

However, the way of supplying oxygen to a patient by using a conventional oxygen mask gradually presents some disadvantages in practical clinical application, and the occurrence of the disadvantages causes that the conventional oxygen mask cannot meet the high standard use requirement in the present field, and the disadvantages of the conventional oxygen mask are specifically described as follows:

1. traditional oxygen mask is in the use, it utilizes the ligature area to walk around patient's auricle periphery and ties up patient's head, however this ligature method, along with oxygen mask's long-time use, very easily cause pressure sore (lifting surface area is little, the pressure increase to patient's auricle position, and the ligature area has the condition of activity friction), the formation of pressure sore, threat patient's that will very big limit healthy and safe, thereby cause the secondary damage to the patient, then extremely be unfavorable for patient's rescue work effectively to go on from this.

2. Moreover, since the autonomous respiratory capacity of the patient with acute heart failure is weak, if the oxygen mask cannot be used again quickly in the process of feeding and medicine feeding to the patient, the effective rehabilitation of the patient is not facilitated, while the traditional oxygen mask needs medical staff to assist the patient in lifting the head of the patient again, then the binding bands are wound around the auricles of the patient, and then the binding bands are tightened, so that the process is time-consuming and labor-consuming obviously, the labor and time of the medical staff are consumed, the working efficiency of the medical staff is reduced to a certain extent, and on the other hand, the longer the wearing time of the oxygen mask is, the time that the patient can breathe oxygen again is prolonged, and the rehabilitation treatment of the patient is directly influenced from the side;

in addition, the patient in the rehabilitation treatment is not convenient to lift the patient randomly, and the patient is accidentally injured secondarily, and the possibility of occupational exposure of the medical staff is increased due to excessive close contact with the patient.

The utility model discloses a multi-functional prevention pressure sore formula oxygen fixed face guard (CN201920199369.8), which discloses specifically "because the oxygen face guard is provided with magic tape, so the nurse can paste the magic tape on different positions of the magic tape according to the fat and thin of the patient's face, ensure that the patient can not have the phenomenon of constraint feeling when fixing the oxygen face guard, when changing the original use of elastic rubber band to fix the oxygen face guard, can cause the oxygen face guard to have constraint feeling to fat people with fat face and to the badness that people with thin face are easy to fall off because of the limited expansion amount of the elastic rubber band, and then realize the benefit that the oxygen face guard is easy to fix and the comfort of the patient is ensured, because of being provided with soft dressing, so the soft dressing can be positioned at the nasal part of the patient when wearing, let it avoid the direct contact of the oxygen face guard and the nasal part of the patient through the softness of the soft dressing, thereby avoiding the occurrence of pressure sores and having better use effect compared with the traditional mode;

although the technical scheme reduces the pressure on auricles and noses when a patient wears the oxygen mask to a certain extent, the traditional connection mode of magic tape adhesion is still adopted, and it needs to be explained here that one mode is that the magic tape has poor fixation when being adhered, the oxygen mask is easy to fall off, and the two modes are that when the patient uses the magic tape to directly contact with the skin, if the face of the patient moves, the magic tape must rub the skin surface of the patient even though the patient moves slightly, so that the comfort of the patient is affected, and meanwhile, the situations of allergy of the magic tape and skin scratch are very easy to occur to the patient;

therefore, the technical scheme disclosed by the multifunctional pressure sore prevention type oxygen fixing mask (CN201920199369.8) does not have clinical practical value, has a plurality of defects, does not really solve the pressure sore problem of a patient wearing the oxygen mask, and is not beneficial to popularization and use.

In the prior art, there is still a granted public utility model patent "an improve oxygen face guard of sore is pressed to bridge of the nose" (CN201921340288.1), its specific disclosure "the bridge of the nose in the face guard main part made by elastic material, under the action of gravity of liquid in the first inner chamber, this bridge of the nose can laminate every patient's bridge of the nose as far as possible to enlarge the laminating area, namely the stressed area of the bridge of the nose, thereby reach and reduce the local pressure and press the beneficial effect of sore with the improvement bridge of the nose";

the technical scheme still adopts a mode of binding a belt to fix the oxygen mask on the face of the patient, and then the contact area of the oxygen mask and the skin surface of the patient is increased only by the gravity of liquid, so that the pressure on the face of the patient is reduced, and the pressure sore on the nose bridge part is relieved;

however, above-mentioned technical scheme still does not solve "band" and auricle position friction, and auricle position pressurized is great, and the patient's auricle that causes presses the problem of sore, and in addition, the whole weight of increase oxygen mask wears the in-process at the patient, also will reduce patient's use comfort level to a certain extent, lacks clinical practical value, does not possess the popularization nature.

It can be seen that it is highly desirable in the art to design an entirely new oxygen mask for use by a patient.
