Description

TECHNICAL FIELD

[0001] The utility model relates to a domestic first-aid oxygen supply device, in particular to an oxygen supply device for home rescue of a patient in acute phase of myocardial infarction. BACKGROUND

[0002] In acute phase of myocardial infarction, there is hypoxic ischemic brain injury. Myocardial infarction can lead to ischemia and hypoxia of myocardium due to occlusion of coronary artery, and pulmonary edema can occur, so more gas exchange is needed to compensate for ischemia and hypoxia caused by myocardial infarction. Therefore, oxygen inhalation and supply are important treatment means for patients with myocardial infarction.

[0003] However, studies have shown that high-concentration oxygen inhalation can significantly increase systemic vascular resistance, increase ventricular filling pressure and pulmonary capillary wedge pressure, reduce cardiac output and stroke volume, reduce coronary blood flow, and affect the diastolic function of the heart of patients with heart failure. The overall results show that high-oxygen therapy is harmful to patients with heart failure.

[0004] The existing domestic first-aid oxygen supply device has two types: 1) a mask for supplying oxygen to a patient, which is easy to operate but can cause the oxygen supply concentration to be too high, thereby having a negative effect on the rescue of patients in acute phase of myocardial infarction; and 2) a nasal catheter for oxygen inhalation, which has a low oxygen supply concentration and allows the patient to be treated by nasal catheter oxygen inhalation, which is beneficial to alleviate the symptoms of dyspnea.

[0005] Under normal circumstances, the patient is supplied with gas by professional medical personnel in a hospital or an ambulance. Although some families are equipped with oxygen bags, oxygen cylinders and other oxygen inhalation devices, the existing domestic oxygen tube for oxygen inhalation does not cause high oxygen, but when inhaling oxygen, the oxygen tube is held by oneself or others, and when the patient in acute phase of myocardial infarction is alone, the nursing staff cannot perform other rescue activities while holding the oxygen tube to supply oxygen to the patient. In addition, the existing oxygen inhalation device is highly specialized, and there is no professional medical staff around the patient, so other people cannot correctly wear the oxygen supply device on the patient in time, and thus the patient cannot be rescued in time.

[0006] Chinese patent document CN115738015A discloses a rapid wearing type first-aid oxygen mask with humidification function. It solves the problem of insufficient humidity in oxygen supply and certain discomfort.

[0007] Chinese patent document CN110755724A discloses an oxygen mask for emergency treatment, which is provided with an oxygen inlet mounting seat at the lower middle part of the mask body and an oxygen inlet pipe head mounted thereon, and is provided with a first-aid air bag. It can quickly use the oxygen mask to supply oxygen to the patient during emergency treatment.

[0008] The existing patent and the commonly used oxygen supply device for small family use supply oxygen to patients by using a mask, and the mask oxygen supply can cause the oxygen supply concentration to be too high, and has a negative effect on the acute phase rescue of myocardial infarction.

[0009] Therefore, the utility model is provided. Utility model content

[0029] The present invention will now be described in detail using the preferred embodiments.

[0030] Example 1

[0031] like Figures 1-7 As shown, an emergency oxygen cylinder for cardiovascular diseases includes an oxygen cylinder body 1, which is a small oxygen cylinder commonly used in households; it also includes an elastic headband 3, an elliptical ring sliding body 4, an oxygen tube bracket 5, and a tube clamp 6; a ring body 11 is fitted and fixed on the oxygen cylinder body 1; the elastic headband 3 is composed of two arc-shaped elastic steel plates, one end of which is fixed to the ring body 11, and the other ends of which overlap and form an annular structure. Arc-shaped protrusions 31 are fixed at the overlapping positions of the elastic steel plates. Arc-shaped protrusions 31 are fixed to the outer side of the elastic steel plate located on the outer side of the ring, and arc-shaped protrusions 31 are fixed to the inner side of the elastic steel plate located on the inner side of the ring. The two arc-shaped protrusions 31 overlap and form an elliptical cross-section structure. The arc-shaped protrusions 31 are made of plastic and are bonded to the elastic steel plates. The elliptical ring sliding body 4 is fitted over two overlapping arc-shaped protrusions 31. The upper end of the oxygen tube bracket 5, which is made of arc-shaped steel sheet, is fixed to the elliptical ring sliding body 4, and the lower end is fixed to the tube clamp 6. The tube clamp 6 is composed of two semi-circular elastic clamping bodies. The outlet valve 2 on the oxygen cylinder body 1 is connected to the oxygen tube 7, and the end of the oxygen tube 7 is clamped in the tube clamp 6. Example 2

[0032] like Figure 3 , 7 As shown, the difference between this embodiment and embodiment one is that the two arc-shaped elastic steel plates of the elastic headband 3 have the same length, and thus the oxygen cylinder body 1 inside the annular body 11 is located behind the annular structure elastic headband 3 formed by the two elastic steel plates. Example 3

[0033] like Figure 8 As shown, the difference between this embodiment and embodiment one is that the two arc-shaped elastic steel plates of the elastic headband 3 are of different lengths, and the oxygen cylinder body 1 inside the annular body 11 is located on the side of the annular structure elastic headband 3 formed by the two elastic steel plates. With this structure, the patient can lie supine.

[0034] How to use:

[0035] In an emergency, the elastic headband 3 is clamped on the patient's forehead, with the oxygen cylinder body 1 positioned behind or to the side of the head. Positioning the oxygen cylinder body to the side of the head makes it easier for the patient to lie supine. The two elastic steel plates of the elastic headband 3 are suitable for patients with different head circumferences, making the operation convenient and quick.

[0036] Sliding the oval ring-shaped sliding body 4 left and right, and adjusting the position of the oxygen tube bracket 5, and placing the oxygen tube bracket 5 in front of the patient's nose; the oval ring-shaped sliding body 4 and the overlapping arc-shaped protrusion 31 are both oval structures, and in the natural state of the elastic component, the oxygen tube bracket 5 is positioned directly below the oval ring-shaped sliding body 4, and the lower end of the arc-shaped oxygen tube bracket 5 is positioned below the patient's nose.

[0037] Inserting the oxygen tube 7 into the patient's nose, and because the tube clamp 6 is elastic, the oxygen tube 7 can be extended or retracted to a suitable depth.

[0038] When the oxygen tube 7 needs to be removed, the lower end of the oxygen tube bracket 5 is pulled back by hand, and the tube clamp 6 and the oxygen tube 7 can be pulled back to disengage the nostrils. At this time, the elastic oxygen tube bracket 5 needs to be pulled with force, and the rotation of the oval oval ring-shaped sliding body 4 causes the oval shape to deform under stress; when the force is released, the oval ring-shaped sliding body 4 and the oxygen tube bracket 5 remain in a natural state, the tube clamp 6 is positioned below the nostrils, and the patient's normal oxygen inhalation is ensured without external force.
