Description

Inflatable decompression oxygen mask

technical field

The utility model relates to an inflatable decompression type oxygen mask, which belongs to the technical field of nursing products.

Background technique

As a form of oxygen therapy, mask oxygen inhalation is used to correct hypoxia, increase the level of arterial partial pressure of oxygen and oxygen saturation, and promote metabolism. It is one of the important methods for adjuvant treatment of various diseases. The oxygen masks currently used clinically are mainly made of polymer materials, including masks, one-way expiratory valves, oxygen delivery connectors, oxygen delivery tubes and mask fixing belts. The wearing method is: cover the mouth and nose with the mask, Then the mask fixing strap (usually elastic band) is wrapped around the head back along the root above the auricles on both sides. Therefore, some patients who use masks for oxygen inhalation for a long time often face these problems in clinical practice: 1. The mask fixing belt directly contacts the patient's skin for a long time, which exerts greater pressure on the patient's ears, nose bridge, bilateral cheeks, and jaw. , long-term compression can easily cause redness or even damage to the auricle and facial skin; 2. The mask fixing strap moves with the movement of the head, causing the mask to shift; 3. The mask fixing strap is entangled with the back of the head, causing pain, and many patients due to Feel unwell and refuse to use it. These will cause a lot of clinical problems: poor oxygen therapy effect, prolonged hospital stay, and increased medical costs; reduced patient cooperation and reduced hospital satisfaction; nursing staff frequently adjust masks or deal with facial broken wounds, which greatly increases the workload.

Preferably, the airbag strap is an adjustable structure, which includes two parts that cooperate with each other, one part is provided with a buckle at the end, and the other part is provided with a plurality of circular holes matched with the buckle.

Preferably, each side of the oxygen delivery pipe is provided with an exhaust device, the exhaust device includes a through hole communicating with each other and a plurality of exhaust holes around it, and the through hole is matched with the piston or the conduit.

Preferably, the oxygen delivery tube is in the shape of a trumpet with a larger cross-section at the connection with the mask body. While providing sufficient oxygen, it can effectively buffer the pressure and avoid the irritation and damage of the patient's nasal mucosa caused by sudden excessive oxygen flow.

While ensuring the effective oxygen therapy of patients, the utility model reduces the occurrence of pressure injury, improves the comfort and cooperation of patients, is simple to manufacture, easy to use, and reduces the pressure of the mask on the bridge of the nose, the cheeks on both sides and the lower jaw. It avoids the direct pressure of the fixed rope on the skin of bilateral ears and back neck, and reduces the incidence of pressure ulcers on the face, ears and back neck. It is an improved decompression suction that can improve the comfort and efficiency of oxygen therapy for patients. Oxygen mask.

Compared with the prior art, the beneficial effects of the present utility model are:

①Relieve compression, improve the comfort of oxygen therapy, and avoid pressure injury;

②Reduce displacement, facilitate fixation, and improve the effectiveness of oxygen therapy;

③It is easy to obtain materials and can be used after repeated disinfection, which is simple, safe and effective;

④The integrated structure saves time and effort and reduces the workload of nursing staff;

⑤ Shorten the length of hospital stay and reduce unnecessary medical expenses.

Description of drawings

Detailed ways

In order to make the present utility model more obvious and easy to understand, preferred embodiments are described below in detail with the accompanying drawings.

Example

As shown in FIG. 1 , an inflatable and decompressed oxygen mask provided by the present invention includes a mask body and adopts a comfortable medical soft silicone material. The mask body is provided with a hollow structure 1 for matching with the patient's auricle, an airbag band 2 for surrounding the patient's head, a nose clip 6 for fixing the patient's nose, an exhaust device for exhaling the patient's breath, and The oxygen delivery tube 9 used to deliver oxygen to the patient's mouth and nose, and the air bag belt 2 communicates with the inflatable air bag 3 .

The hollow structure 1 can prevent the auricle from being directly compressed, and at the same time, the mask body can be hung on the ear when the mask fixing strap is accidentally dropped, so as to maintain effective oxygen use.

The airbag belt 2 is flat, which can reduce the compression and improve the comfort after inflation. The airbag belt 2 is an adjustable structure, which includes two parts that cooperate with each other, one part is provided with a buckle 4 at the end, and the other part is provided with a plurality of circular holes 5 matched with the buckle 4 . The plurality of round holes 5 are convenient to adjust the length according to the head circumference of the patient. When fixing, the round holes 5 are placed above the buckle 4 with the protruding surface facing outward.

The inflatable air bag 3 uses a syringe to inject air, which is convenient to observe and adjust the pressure in the air bag.

An exhaust device is provided on both sides of the oxygen delivery pipe 9. The exhaust device includes a through hole that communicates with each other and a plurality of exhaust holes 7 around it. The through hole is matched with the piston 8 or the conduit. The piston 8 is unscrewed and folded outward, and the nasogastric tube can be passed through the through hole, which is convenient for the fixation and observation of the catheter, and avoids air leakage and the occurrence of the mask compressing the catheter. When there is no catheter, the piston 8 is folded inward and plugged. A through hole will do.

The oxygen delivery tube 9 is trumpet-shaped with a large cross-section at the connection with the main body of the mask. While providing sufficient oxygen, it can effectively buffer the pressure and avoid the irritation and damage of the patient's nasal mucosa caused by a sudden excessive oxygen flow.

The process of using the above oxygen mask is as follows:

1) Put on a mask corresponding to the auricle of the patient with the hollow structure 1, and the mask is hung on the auricle for initial fixation;

2) According to the size of the patient's head circumference, adjust the length of the airbag belt 2, buckle the corresponding round hole 5 above the buckle 4, and fix it again;

3) according to the height of the patient's nose bridge, adjust the width of the nose clip 6;

4) Use a syringe to inject gas into the inflatable air bag 3, and perform pressure measurement and final fixation;

5) For those with a nasogastric tube, etc., fold outward to open the piston 8, and the catheter is pierced through the through hole and fixed outward to avoid mask compression of the catheter and air leakage. For those without a catheter, the through hole is always in a closed state;

6) Connect the oxygen supply 9, and adjust the oxygen flow according to the doctor's advice.
