Description
Technical field
This utility model relates to medical apparatus and instruments, more particularly, relates to the air flue moisturizing muffler of tracheotomy patients.
Background technology
Research shows, saturation water vapour content when to arrive the humidity requirement of alveolar be 44mg/L(37 DEG C), in theory upper respiratory tract for alveolar provide 75% heat and humidity and 33mg/L.But the suction gas of tracheotomy patients directly enters lower respiratory tract from artificial airway, lose that upper respiratory tract is heated, the effect of humidification, gas can only absorb moisture from respiratory tract itself, and cause respiratory mucosa dry, loss of moist can reach 800ml/d.Investigation display, because humidifying is not enough, the plugging rate of tracheotomy patients of being in hospital is 14%-43%.More alarming, a lot of Pipe Cutting incision band pipe is left hospital or permanent trachea fistulation patient does not have relevant humidifying product in daily life to ensure the humidity of its air flue, and this may cause respiratory mucosa dry.
At present, adopt hot and humid area device (artificial nose) to improve status of patient clinically, artificial nose is the fine-meshed screen yarn constructional device be made up of several layers of absorbent material and hydrophilic compounds.The method is passive wetting approach, utilizes the humidity humidifying suction gas of human body self breath.But this product exists multiple taboo, as the patient with courage and uprightness, thickness, a large amount of secretions; Low tidal volumes patient (large bronchopleural fistula, airway tube cuff fault, without cuff airway tube, the patient using lung preversation ventilation strategies) etc.Meanwhile, use hot and humid area device can increase dead space and the resistance of patients with mechanical ventilation, thus increase patient respiratory acting.In addition, the price of each artificial nose is higher, about about 80-100 yuan.
Wet gauze cladding process be also clinical in the normal method adopted, get normal saline wet gauze 2 ~ 3 layers and be covered in tracheal casing pipe collar extension place, change at any time, keep gauze moist, can ensure to suck that gas in respiratory tract is moistening can prevent foreign-body aspiration again like this.Its filtration of the gauze used in the method is all lower with humidifying ability, can not make up the upper respiratory tract function that tracheotomy patients loses.Gauze fixing more difficult and easily polluting, operability is poor.
Summary of the invention
Technical problem to be solved in the utility model is, provides one to prevent tracheotomy patients respiratory mucosa dry, maintains the air flue moisturizing muffler of its respiratory tract normal function.
In order to solve the problem, this utility model provides air flue moisturizing muffler, comprises fixing band and cover body, described cover body semicircular in shape, and cover body comprises skin, middle level and internal layer three-decker, and described skin is filter course, and middle level is moisturizing layer, and internal layer is cotton layer.
As a preferred version, described filter course is grenadine structure, macromolecular particle in filtered air.
As a preferred version, described moisturizing layer is the fine-meshed screen knot structure that absorbent material and hydrophilic compounds are made.
The utility model has the advantage of, it is good that (1) filters moistening effect, airway mucus can be prevented dry, maintain the respiratory tract function of tracheotomy patients.(2) safe wearing, comfortable, attractive in appearance, is easily accepted by tracheotomy patients.(3) easy to operate, and be easy to observe and change, layman also can safeguard, benefits wide.(4) easy to make, advantage of lower cost, popularization is stronger.

Detailed description of the invention
Elaborate to this utility model below in conjunction with accompanying drawing, the purposes of embodiment is only to explain the present invention and non-limiting technical scheme.
Embodiment
As shown in Figure 1, air flue moisturizing muffler comprises fixing band and cover body, described cover body semicircular in shape, and cover body comprises skin, middle level and internal layer three-decker, and described skin is filter course, and middle level is moisturizing layer, and internal layer is cotton layer.Fixing band is contton cloth, and more comfortable during contact skin, muffler is fixed on head and neck by these two belts, and muffler is covered on artificial airway's mouth of tracheotomy patients.
Fig. 3 is the profile of air flue moisturizing muffler cover body, and skin is filter course, the grenadine structure of macromolecular particle in filtered air, middle level is moisturizing layer, the fine-meshed screen knot structure be made up of absorbent material and hydrophilic compounds, and internal layer is cotton layer, be made into by contton cloth, more comfortable during contact skin.
This utility model retains the principle of moisture based on filtering particle, utilize the humidity of human body self breath, the gas that humidifying sucks, thus make up the function that tracheotomy patients cannot use upper respiratory tract humidified gas, prevent airway mucus dry, cause the problem that mucus thickness even blocks.The concrete grammar of its effect is as described below: with fixing band (being illustrated as two belts), air flue moisturizing muffler is trapped among patient's cervical region, covers body part covers on artificial airway's mouth, when patient exhalation air, gas is by the covers body part of air flue moisturizing muffler, and the moisture in breath has been retained on the middle level (moisturizing layer) of cover body.During patient breaths, first suction gas passes through skin (filter course), and the large granular impurity in air is stopped by outer (filter course), filters out the air of large granular impurity then through middle level (moisturizing layer), enter air flue with the moisture that middle level is adsorbed, play the effect of air flue moisturizing.Air flue moisturizing muffler mechanism of action is see Fig. 4.
This device air flue moisturizing muffler is safer compared to " dripping type humidifying method ", " respiratory tract lavage ", can not cause patients with lower respiratory tract infection, can be used as long-term humidifying article.Compared with " aerosol rebreathing method ", " hot type humidifier ", belong to passive humidifying product, carry out humidifying airway by the moisture retaining human body self respiratory, safely, effectively, and can life-time service.Most importantly, service condition needed for this device air flue moisturizing muffler is simpler than " aerosol rebreathing method ", " hot type humidifier ", convenient, can benefit unit patients, discharged patients and can the tracheotomy patients of autonomous respiration.
" hot and humid area device " is because be enclosed in pipe by absorbent material and hydrophilic compounds, then pipe is connected on tracheotomy patients artificial airway, so when patients produce's thing or blood is more sticks on absorbent material in pipe and hydrophilic compounds, be easy to cause airway obstruction, meanwhile, because tubular structure, cause the increase of invalid dead space and resistance, the breathing acting of patient is increased, and is a kind of burden for old patient.But this device air flue moisturizing muffler covers on artificial airway's mouth of tracheotomy patients, do not increase invalid dead space and resistance.
Finally, this device air flue moisturizing muffler has clear superiority compared to " wet gauze cladding process ", and be easy to fixing, humidifying filtering function is remarkable.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from this utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
