Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, specifically a kind of respiration filtering device.
Background technology
As everyone knows, normal adult will suck the 10000-12000L air every day, nasal cavity and mouthful, pharyngeal mucous membrane surface is long-pending very big, blood circulation is very vigorous, can make and suck that air is heated, humidification or impel suction gas heat radiation above body temperature.Thereby in the ordinary course of things, because the regulating action of respiratory tract regardless of the composition that sucks gas, character, when reaching alveolar, can both be transferred near body temperature (37 ℃), relative humidity is the alveolar gas of a hundred per cent (100%).Long-term suction is dry, cold gas can cause the respiratory tract dehydration, fibre function goes down, even suffers from tracheitis, bronchitis.As sucking the similar gas that contains saturated steam, just can avoid losing of moisture and heat to the body temperature temperature.Every liter contains millions of particles approximately in the suction air, so lung must have various protection mechanisms to remove the grit and the antibacterial of suction.Respiratory tract has filtration to sucking gas, and the granule that sucks in the gas constantly clashes into air-flow so that be deposited on the mucosa of respiratory tract, and with the granular size difference, deposition site is also different.When artificial airway forfeiture or weakened the suction gas regulating function the physiological condition under greatly, then must manually heat, humidification, to protect the normal performance of respiratory mucosa, cilium and body of gland function.At present, in medical treatment and nursing, artificial nose, warm and humid exchanger, it is collected the heat in the expired gas and aqueous vapor and utilizes with anesthesia respiration the defecator warm and gas that humidifying sucks, be mainly used in the patient and set up the artificial airway, under the situation of nose breathing, use.Existing artificial nose, warm and humid exchanger arrangement complexity, the cost height.
Summary of the invention
Technical problem to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art, provide a kind of simple in structure, easy to use, moisture absorption and high insulating effect, effectively stop extraneous foreign body and antibacterial dust, prevent cross infection, the respiration filtering device that the ratio of performance to price is high.
The technical scheme in the invention for solving the above technical problem is: a kind of respiration filtering device, it is characterized in that: it comprises upper shell, lower house, dust removal and filtration purifying layer, suction heat-insulation layer, lower house is an infundibulate, its underpart is provided with a pipe joint, upper shell is fastened on the lower house bulge loop pedestal, the upper end is provided with a pipe joint, and dust removal and filtration purifying layer and suction heat-insulation layer are filled in the lower house infundibulate cavity volume between upper shell, the lower house.
This utility model dust removal and filtration purifying layer is clipped between upper shell and the interior pedestal of lower house, plays the dust removal and filtration effect.The suction heat-insulation layer fills up lower house infundibulate cavity volume, plays moisture absorption, insulation effect.The pipe joint of upper shell, lower house is communicated with endotracheal tube and breathing corrugated tubing respectively, cooperates respirator and anesthetic machine to use.Against existing technologies, this utility model is simple in structure, and is easy to use, and moisture absorption and high insulating effect can effectively stop extraneous foreign body and antibacterial dust, are applicable to the disposable use of patient, avoid cross infection, ratio of performance to price height.
Description of drawings
Below in conjunction with accompanying drawing this utility model is done to describe further:
Fig. 1 is a structural representation of the present utility model.
1. upper shells among the figure, 2. dust removal and filtration purifying layer, 3. suction heat-insulation layer, 4. lower house, 5. pipe joint, 6. block supports, 7. pipe joint, 8. thief hatch, 9. bulge loop pedestal, 10. in pedestal.
The specific embodiment
As can be seen from Figure 1, a kind of respiration filtering device, it comprises upper shell 1, lower house 4, dust removal and filtration purifying layer 2, suction heat-insulation layer 3 etc.Upper shell 1, lower house 4 adopt the non-toxic plastic processing and fabricating.Lower house 4 is an infundibulate, and its underpart is provided with a pipe joint 5, and top is provided with bulge loop pedestal 9 and interior pedestal 10, and upper shell 4 is fastened on the lower house bulge loop pedestal 9, and the upper end is provided with a pipe joint 7, also is provided with thief hatch 8 and block support 6 on the upper shell 4.
Be filled with dust removal and filtration purifying layer 2 and suction heat-insulation layer 3 in the lower house infundibulate cavity volume between this utility model upper shell 1, the lower house 4.Dust removal and filtration purifying layer 2 adopts dust removal and filtration medium efficiently, and as glass fibre membrane etc., it is clipped in upper shell 1 and the lower house between the pedestal 10, plays the dust removal and filtration effect.Suction heat-insulation layer 3 is filled in the lower house infundibulate cavity volume, plays moisture absorption, insulation effect, also filtration on the other hand on the one hand.Can adopt medical foam to do substrate in the suction heat-insulation layer 3, can be substrate with the hydrophilic fiber material also, has very strong water absorption, and selecting calcium chloride for use is antibacterial, can strengthen water absorption.Its structure can be double-deck Concha Arcae paper mold, through twining, curling, forms a plurality of parallel passage aisles, is calcium chloride between the two layers of paper, is the coarse particles shape.After curling, adopt low cutting technique, prevent subsiding of passage aisle, can enlarge exchange area like this, reduce airway resistance.And has a heat preservation energy-saving effect efficiently.Its pore size filter reaches 0.027 μ m, and filter efficiency reaches 99.99999%, and far below the coronavirus diameter, respiratory resistance is very little, can be detained the moisture and the heat of the patient expired overwhelming majority, thereby effectively keeps the air flue humiture.
When this utility model uses, be placed on endotracheal tube and breathe between the corrugated tubing cooperation respirator and anesthetic machine use.In the whole process of mechanical respiration, the patient respiration road remains certain moisture.Like this, help protecting mucus cilium system motion normal, reduce the heat forfeiture, reduce the chance that body temperature is lost, can guarantee return pipe road drying again, reduce bacteria breed, the generation of protecting from infection.Can effectively stop extraneous foreign body and antibacterial dust.Coming off of micro fiber avoided in use, protects patient safer and more effectively.Cross infection is avoided in the disposable use of this utility model, ratio of performance to price height.
