Description

Technical Field

[0001] The invention relates to a medical protective product, in particular to a medical protective mask. Background Art

[0002] In the prior art, there are many kinds of medical protective clothing for epidemic prevention, which generally need to be worn in conjunction with goggles, protective masks, protective caps, protective clothing, etc. After various protective equipment are worn together, there will be connection gaps between each other. When the gaps are poorly airtight, there will be a risk of easy invasion of viruses or bacteria. In order to reduce the risk, medical staff must wear protective clothing for a long time and wear protective glasses and protective masks tightly based on the requirements of epidemic prevention. These facial wear products are pressed tightly against the skin for a long time, causing problems such as compression edema, sweat stains and wrinkles, indentation and poor blood flow, and skin trauma, causing great pain to medical staff.

[0003] At the same time, since the various protective equipment on the whole body is not an integrated structure, the wearing process is complicated, cumbersome and time-consuming, and the process of putting on and taking off invisibly increases the physical exertion and inconvenience of medical staff. The lack of wearing comfort and insufficient breathing of protective equipment are all reasons that aggravate the fatigue of medical staff.

[0004] Furthermore, the goggles in the prior art lack the function of removing mist drops, and are lack of compound antiviral and sterilization protection treatments. Long-term use can easily form mist drops and water flows on the goggles, which also increases the risk of viruses or bacteria threatening medical staff and increases the difficulty of visual judgment for medical staff during treatment.

[0050] The wearing method of the protective clothing mask described in this embodiment is generally as follows:

[0051] Wear a protective mask 1 on the head, straighten the goggle lens 4 on the protective mask that forms an integrated structure with the arc-shaped plastic sheet 20 on the head to face the visual range, and the dry and leak-proof head sweat-absorbing support block 21 of the integrated structure is at a comfortable position on the forehead, put on the head fitting and fixing elastic 2 of the protective mask, and use the anti-elasticity buckle 3 to prevent the head fitting and fixing elastic 2 from falling off from the forehead. Unfold the mask face fitting waterproof elastic support 5 and the mask face fitting support 6, the mask 7 faces the nose and mouth, stretch the mask chin fitting support 8 and the mask chin fitting support elastic rope 9, and adjust the fit of the mask. At the same time, the mask chin fitting support elastic rope 9 is connected to the support height adjustment open double ring fixing buckle 23 of the goggles support frame 22, and the mask chin fitting support elastic rope 9 passes through the double rings to form a fixation by using the open double ring structure of the fixing buckle, and the position of the support height adjustment open double ring fixing buckle 23 is adjusted to obtain a suitable support height of the goggles. Follow the chin-fitting elastic support strap positioning guide buckle 10 of the mask, tighten the chin-fitting support strap elastic rope 9 of the mask connected to the protective cover eyepiece support height adjustment opening double-ring fixing buckle 23 at the back of the head, and use the elastic rope lock buckle 16 set at the back of the protective mask head to fix it, and at the same time adjust the head fitting and fixing elastic adjustment rope 15 to obtain a comfortable fitting position of the head of the protective mask, and fix it with the elastic rope lock buckle 16 at the back of the protective mask head. The elastic rope lock buckle 16 can also be used to tighten and fix the facial fit of the protective mask for comfort.

[0052] The chin-fitting elastic cord 9 of the mask and the positioning guide buckle 10 of the elastic support strap along the chin of the mask can also form a certain degree of tightening at the neck position, so as to form the overall fit of the protective mask to the head below the mandibular angle, which is convenient for medical staff to inspect and judge treatment measures such as downward and sideways rotation of the head.

[0053] For wearing a single seamless, airtight, and easy-to-adjust non-compression protective mask, unfasten the armpit fixing ring release buckle 13, pass the armpit fixing ring 12 around the armpit to form a ring at the shoulder and armpit, and fasten the armpit fixing ring release buckle 13, so as to prevent the protective mask from loosening and moving. Further, after flattening and fixing the chest fitting adjustment folding adhesive cover 11, put on the one-piece protective suit.

[0054] The goggles support frame 22 and the support height adjustment open double-ring fixing buckle 23 are connected to the mask chin fitting support elastic cord 9 through the open double-ring fixing buckle, and the position of the support height adjustment open double-ring fixing buckle 23 can be adjusted to obtain a suitable goggles support height, and a support space for the mask is formed.
