Description

Technical Field

[0001] The utility model relates to the technical field of breathing masks, in particular to a breathing mask. Background Art

[0002] A respiratory mask is a medical device used to cover the patient's mouth and nose during anesthesia, mechanical ventilation or oxygen therapy to provide necessary respiratory support. The components of a respiratory mask include a main body, a sealing pad, an interface and a headband. The main body is the skeleton of the mask, usually made of plastic or metal, and is used to support and fix other parts. The function of the sealing pad is to fit the patient's face tightly to prevent air leakage. The interface can be connected to a ventilator or oxygen source to transmit gas to the patient's respiratory tract. The headband plays a fixing role, allowing the mask to be stably fixed on the patient's face. The respiratory mask used in the anesthesiology department is usually a specially designed mask used to cover the patient's mouth and nose during anesthesia for mechanical ventilation or oxygen therapy.

[0003] The existing Chinese patent with announcement number CN210145254U discloses a breathing mask, which relates to the field of medical product technology, including a mask body and an air inlet pipe arranged on the mask body, the mask body is provided with a replacement groove running through the front and back, a rotatable replacement box is provided in the replacement groove, the replacement box includes a first side and a second side facing away from each other, the first side is provided with air freshener gel, and the second side is provided with activated carbon, which can effectively remove odors such as plastic.

[0004] However, the above device has the following disadvantages: the above breathing mask is fixed to the face by a fixing belt, which is tied to the back of the head. The fixing belt is generally an elastic belt, which is automatically adjusted according to the size of the patient's head. However, an operation takes a long time, and the patient needs to wear the breathing mask for a long time. The elastic belt will strangle the back of the patient's head, causing the patient to feel uncomfortable. In addition, some patients have small heads, which results in the elastic belt being unable to fix patients with small heads after long-term use. Utility Model Content

[0012] The utility model is further configured as follows: a side wall of the anti-strangulation strip is provided with absorbent cotton.

[0013] By adopting the above technical solution, the anti-stretching strip is in contact with the skin for a long time, sweat will flow out, and the absorbent cotton can absorb the sweat to increase comfort.

[0014] The utility model is further configured as follows: an air bag is fixedly mounted on the side wall of the breathing mask body.

[0015] By adopting the above technical solution, the airbag is relatively soft, and when the breathing mask contacts the face, the effect of preventing the face from being strangled is achieved. In addition, the airbag can ensure that the breathing mask and the face are in full contact, thereby increasing the practical performance and safety protection performance of the device.

[0016] The utility model is further configured as follows: an inflation port is provided at the top of the airbag.

[0017] By adopting the above technical solution, the airbag can be inflated through the inflation port, thereby increasing the practical performance of the device.

[0018] In summary, the utility model has the following beneficial effects: the breathing mask body of the utility model is the prior art, and its function is to supply oxygen to the patient, so it is not described in detail. After the breathing mask body is covered on the patient's face, the elastic bands at both ends are pulled out from the through holes of the fixing block, the lengths of the two ends of the elastic bands are adjusted, and then the bolts are tightened to fix the elastic bands. The anti-strangulation strip can protect the head and the sides of the face, and while the length of the elastic bands can be adjusted, the head and face can be prevented from being strangled, thereby increasing the practical performance of the device. In addition, the above-mentioned device can disassemble and replace the elastic bands to prevent the elastic bands from being worn out due to long-term use, thereby affecting the normal fixation of the breathing mask body.
