Description

Helmet type non-invasive ventilator mask

technical field

The utility model relates to the field of auxiliary medical equipment, in particular to a helmet-type non-invasive ventilator mask.

Background technique

Non-invasive ventilators are clinically used to treat sleep apnea syndrome and related diseases, especially in the Department of Respiratory Medicine. The masks include nasal masks and mouth and nose masks. During work, the ventilator host provides gas pressure for patients' non-invasive ventilation therapy. The power source, the gas with a certain pressure is delivered to the mask through the ventilator pipeline, and then enters the lungs through the respiratory tract. To achieve the effectiveness of non-invasive ventilation, the mask is the key. The existing clinical masks are more convenient to use and are well fixed. Under certain circumstances, the airtightness of the mask can be realized to achieve the therapeutic effect.

In order to achieve the therapeutic effect, when using a nasal mask or a mask, it generally needs to be tightly fitted to the patient's nose and face, which will cause the patient's comfort to decrease, and there are problems of poor patient tolerance and compliance during use. However, long-term wearing can also cause pressure injuries on the face and the bridge of the nose, and the existing face shields are not firmly fixed and have poor airtightness.

Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

The utility model provides a helmet-type non-invasive ventilator mask. Its working principle is to replace the traditional mouth and nose mask with a helmet-type mask, and to set a circle of inflatable airbags at the bottom of the mask to effectively fix the mask and improve the mask. The purpose of air tightness and patient comfort.

Below in conjunction with embodiment and specific implementation mode the utility model is described in further detail.

As shown in Figure 1, a helmet-type non-invasive ventilator mask, the mask includes: an outer cover body 1, the outer cover body 1 is a transparent cover body with an opening at the bottom, and an inner cover body is fixedly installed inside the outer cover body 1 Liner 2, the bottom ends of both sides of the inner liner 2 are equipped with adjustable fixing belts 3, the bottom ends of the adjustable fixing belts 3 are connected with a chin support 4, and the bottom of the outer cover body 1 is provided with a circle of inflatable airbags 5, so that The inflatable airbag 5 is provided with a spherical inflator, the spherical inflator 6 is provided with an airbag exhaust valve 7 near the inflatable airbag 5, and the side wall of the external cover 1 is provided with an oxygen inlet pipe 9 , non-invasive breathing access tube 10 and face mask exhaust hole 8, one end of the oxygen access tube 9 and the non-invasive breathing access tube 10 is arranged inside the outer cover body 1, and the other end is arranged outside the outer cover body 1, and the An air hole cover is arranged on the face mask exhaust hole 8 .

Wherein, two cover body fixing belts 11 are provided at the left and right ends of the bottom of the outer cover body 1 , and the cover body fixing belts 11 are used for fixing the outer cover body 1 .

Wherein, one end of the cover fixing belt 11 is fixed to the rear end of the outer cover 1 , and the other end of the cover fixing belt 11 is fixed to the front end of the outer cover 1 .

When medical personnel wear a helmet-type non-invasive ventilator mask to a patient, they first connect the ventilator pipeline with the oxygen inlet tube 9 and the non-invasive breathing tube 10 on the mask, and then wear it on the patient after the doctor has adjusted the parameters. At this time, the inflatable airbag 5 at the bottom of the mask is not inflated. After wearing it, adjust the position and inject gas into the inflatable airbag 5 through the spherical pump 6 until the airbag at the bottom of the mask fits the patient's neck completely without air leakage. Turn on the ventilator to check whether the mask is in good condition. The design of the airbag at the bottom of the mask is adjustable, suitable for different groups of people. The airtightness of the mask can be achieved by adjusting the tightness of the airbag, reducing air leakage, and avoiding the repeated care of the patient by the nursing staff due to air leakage. Adjust the face mask, thereby saving the workload, and the bonding area between the inflatable air bag 5 and the neck is relatively large, and the local pressure will be reduced, thereby reducing the damage to the local skin. Secondly, this design mask does not directly contact the nose. Contact with the head or face avoids pressure damage to the nose and face, increases the patient's comfort, tolerance and compliance with the ventilator, and improves the treatment effect.

There are two fixing straps under the outer mask body 1, and the fixing straps pass through the patient's armpit to effectively further fix the mask and improve the fixation and airtightness of the mask.

The above is only a preferred embodiment of the helmet-type non-invasive ventilator mask disclosed by the utility model. Several deformations and improvements can also be made, all of which belong to the protection scope of the present utility model.
