Description

Technical Field

[0001] The embodiments of the utility model belong to the technical field of ventilator masks, and more specifically, relate to a gasket-protected anti-pressure sore ventilator mask. Background Art

[0002] The ventilator occupies a very important position in the field of modern medicine. It is a kind of medical equipment that can prevent and treat respiratory failure, reduce complications, and save and prolong the life of patients. Non-invasive ventilators are easy to use and do not require tracheal intubation. In comparison, they greatly reduce the pain of patients. However, there are also some nursing risks in the process of using non-invasive ventilator-assisted ventilation treatment, such as poor wearing and tightening of the ventilator mask. When the mask tightening force is too large, it will cause some facial tissues to be compressed, causing facial pressure sores. Once pressure sores occur, it will seriously reduce the patient's tolerance and compliance to the ventilator and affect the treatment of the disease; and the method of reducing the probability of pressure sores by reducing the tightening force of the mask will cause the defect of reduced airtightness of the ventilator mask. Therefore, it is of great significance in the field of medical nursing to propose a device that can reduce the probability of pressure sores while ensuring the airtightness of the ventilator mask.

[0003] In order to solve the above technical problems, Chinese utility model patent CN213191969U discloses an anti-pressure sore breathing mask, including a mask body, an oxygen duct and an exhaust hole are arranged on the mask body, an upper ear plate A and an upper ear plate B are respectively connected to the left and right sides of the upper part of the mask body, and a lower ear plate A and a lower ear plate B are respectively connected to the left and right sides of the lower part of the mask body, the upper ear plate A, the upper ear plate B, the lower ear plate A and the lower ear plate B are respectively connected to the upper strap A, the upper strap B, the lower strap A and the lower strap B, the inner left parts of the upper strap A and the lower strap A are respectively provided with upper Velcro and lower Velcro, the outer right parts of the upper strap B and the lower strap B are respectively provided with upper Velcro and lower Velcro, the inner side of the mask body is connected to an anti-pressure sore pad, an air supply pipe is passed through the anti-pressure sore pad, massage particles are arranged in the decompression cavity of the anti-pressure sore pad, and a decompression spring is connected to one side of the massage particles; the breathing mask of the utility model has the advantages of being easy to wear , high fit, avoidance of pressure sores, and strong comfort; in addition, Chinese utility model patent CN210785872U discloses an anti-pressure sore breathing mask, including: a mask shell, an air inlet connector, an elastic band and a mask ring, the mask ring is set on the outer ring of the mask shell, the elastic band is set on the opposite sides of the mask shell, the mask ring includes: a mask ring shell, a pressure sore prevention dressing and an adjustment plug, the pressure sore prevention dressing is set on the side of the mask ring shell away from the air inlet connector, the mask ring shell is provided with a first air bag away from the mask shell and a second air bag close to the mask shell, an adjustment hole is provided between the first air bag and the second air bag, the side wall of the adjustment hole is provided with a connecting hole connecting the first air bag and the second air bag, and the adjusting plug is rotatably arranged in the adjustment hole to make the connecting hole conductive or closed. The anti-pressure sore breathing mask provided by the utility model can prevent the formation of pressure sores by alternating squeezing of the pressure sore prevention dressing and the air bag.

[0004] The above patent technology only reduces the pressure of the mask on the human face by adding an air cushion, thereby reducing the occurrence of pressure sores. However, the following technical problems still exist: (1) The ventilator mask is usually fixed to the patient's head by a tightening belt, and the compression of the tightening belt and the face will also cause indentations and even pressure sores, while the above patent technology only solves the pressure sore problem of the main part of the mask; (2) Factors that cause pressure sores include mechanical factors and physical and chemical factors. Mechanical factors include positive pressure, shear force, and friction force caused by the mask on the human facial skin, while physical and chemical factors include sweat and oil on the human face, which will increase the probability of pressure sores. The above patent technology only proposes a technical solution for mechanical factors, while ignoring the influence of physical and chemical factors; (3) In terms of adjusting the tightening force of the mask, the above patent technology only completes the fixation of the mask by manually adjusting the adjustable tightening belt, but the manual adjustment method still cannot accurately control the tightening force. The randomness of the manual adjustment process leads to a certain degree of randomness in the control of the tightening force. Utility Model Content

[0048] like Figures 1 to 5 As shown, in the embodiment of the utility model, the mask tightening unit 4 includes:

[0049] An upper tightening belt 410 and a lower tightening belt 420 fixed to the airtight cover 110;

[0050] A shape adaptability adjustment component 430 is used to adjust the length of the upper tightening belt 410 and the lower tightening belt 420.

[0051] like Figures 3 to 5 As shown, in the embodiment of the utility model, the upper tightening belt 410 includes:

[0052] An upper belt edge air cushion 411 disposed at the inner edge of the upper tightening belt 410 , and an air cushion air injection end 412 connected to the upper belt edge air cushion 411 .

[0053] like Figure 4 As shown, in the embodiment of the utility model, the mask base assembly 1 also includes:

[0065] At the same time, the utility model not only achieves pressure buffering by adding an air cushion layer separately at the mask, but also the slight movement of the mask is timely buffered and absorbed by the air cushion layer, which to a certain extent hinders the movement of the facial skin and weakens the shear force generated by the mask on the skin, thereby further reducing the probability of pressure sores.

[0066] The utility model ensures facial cleanliness by adding a dirt suction protection component. From the perspective of physical and chemical factors, this solution realizes the timely adsorption and cleaning of facial sweat and oil. It has a simple structure but can effectively reduce the pathological evolution of pressure sores. In addition, the soft silicone gasket ensures a good fit between the mask and the human face, preventing the occurrence of air leakage. And by adopting the method of inflating external support, precise control of the tightening force is indirectly achieved.
