Description

Improved respirator mask

Technical Field

The utility model belongs to the technical field of the medical appliances technique and specifically relates to a modified breathing machine face guard.

Background

Non-invasive positive pressure ventilation (NIPPV) refers to ventilation performed without an artificial airway (endotracheal intubation or tracheotomy), and is an artificial ventilation method in which a ventilator is connected to a patient via a nasal mask, and positive pressure support is provided by the ventilator to assist ventilation. Non-invasive positive airway pressure (CPAP) therapy comprises continuous CPAP, bi-level CPAP and intelligent CPAP, and the bi-level CPAP achieves consensus on the treatment effect of patients with Chronic Obstructive Pulmonary Disease (COPD). Because the chronic obstructive pulmonary disease cannot be cured, the treatment aims to control the disease condition, prolong the survival time, reduce complications, improve the survival rate, reduce the medical expense and the like, has obvious effects and avoids the success rate of re-intubation reaching about 70 percent. The nasal feeding method is a method in which a catheter is inserted into the stomach through the nasal cavity and liquid food, water, and medicines are poured into the tube. The need for maintaining patient nutrition and therapy by nasogastric tube feeding food and medication to patients who cannot self-eat orally. In the face of a patient needing to use the nasogastric tube and the breathing mask at the same time, the nasogastric tube and the breathing mask are completely and independently separated, and one part of the nasogastric tube is continuously pressed by the edge of the mask, so that the air leakage alarm of the mask is easily caused, and the treatment effect is influenced by the pressure sore on the face.

With the aging population, nasal feeding patients are remarkably increased, and in recent years, data show that the number of patients using noninvasive ventilators at home is increased, so that the nasal feeding patients become a serious social problem. The current face guard is that the department of respiration uses noninvasive ventilator patient special, and the patient can't feed simultaneously, if keep somewhere behind the nasogastric tube, because all oppress in cheek portion, the comfort level is poor, is showing to influence treatment.

Chinese patent documents: cn201920180609.X, application date 2019.01.31, patent name: an anti-indentation breathing machine mask. An anti-indentation respirator mask is disclosed that includes a mask body, a base pad, and a connecting band. The mask body is provided with air holes and pressure reducing holes, the edge of the mask body is provided with a connecting buckle, the base pad is arranged on the periphery of the bottom of the mask body and is detachably connected with the mask body, the connecting band is connected with the mask body through the connecting buckle, and the base pad is a polyvinyl alcohol pad or a memory sponge pad.

Chinese patent documents: CN202120552152.8, application date 2021.03.17, patent name: a noninvasive ventilator mask for weakening indentation. The utility model discloses a weaken noninvasive ventilator face guard of indentation, including respirator, respirator's edge is provided with widens sealed emulsion ring, the inside of widening sealed emulsion ring is provided with the buffering cavity, the internal surface integrated into one piece of buffering cavity has the buffer board, respirator and widen and be provided with spacing subassembly between the sealed emulsion ring, the upper surface of respirator one end both sides surface and the other end all is fixed with the location connecting rod.

The anti-indentation respirator mask disclosed in the patent document CN201920180609.X solves the problems that the mask in the prior art is easy to leak air and the face of a patient is indented and skin is broken after a head band is tightened in order to avoid air leakage, a dressing is not required to be filled between the mask and the face when the mask is used, the mask is high in comfort level and low in cost, the mask body and the base pad are detachably designed, the mask is convenient to clean and replace, the service life of the base pad is prolonged while bacteria are prevented from breeding, when the base pad is damaged, only the base pad part can be replaced, and resources are further saved; and in patent document CN202120552152.8, a weaken noninvasive ventilator mask of indentation, edge through respirator is provided with widens sealed emulsion ring, make respirator cover when patient's oronasal department, increase the area with the facial contact of patient through widening sealed emulsion ring, reduce respirator to the pressure of patient's facial unit area, it causes facial indentation too big to avoid the patient to wear respirator for a long time, respirator and widen to be connected through spacing subassembly between the sealed emulsion ring simultaneously, the convenience of widening sealed emulsion ring and respirator is connected has been increased. However, the improved respirator mask has no relevant report at present, wherein the special mask is made of selected materials according to the position of the mask fixed on the face of a nasal feeding patient, and the respirator reduces air leakage and alarms after being worn by fixing the nasal feeding tube, so that the comfort level is improved, the treatment effect is ensured, the hospitalization time is shortened, the medical resources are saved, and the hospitalization cost of the patient is reduced.

To sum up, need urgently need one and use the face guard in the fixed position of face according to nasal feeding patient, the special face guard of material preparation, through fixed nasal feeding pipe, wear back breathing machine and reduce the gas leakage and report to the police, improve the comfort level, guaranteed treatment, shorten the time of being in hospital, practice thrift medical resource, reduce patient's cost of being in hospital an improved breathing machine face guard.

Disclosure of Invention

The utility model aims at overcoming prior art's not enough, provide one kind and use the face guard in facial fixed position according to nasal feeding patient, the special face guard of material selection preparation through fixed nasal feeding pipe, wears the back breathing machine and reduces gas leakage and reports to the police, improves the comfort level, has guaranteed treatment, shortens the time of being in hospital, practices thrift medical resource, reduces the patient and is in hospital a modified breathing machine face guard of expense.
