The technical solution adopted by the present invention is that: a kind of medical antibacterial calcium lime, by raw materials of Ca (OH)243-46 parts, NaOH 1.2-2.2 parts, 1-1.5 parts of hygroscopic agent, 0.5-1 parts of bacteriostatic agent, 0.2-0.5 parts of pH indicator, 1.2-2.8 parts of expanding material, water 6-9 parts are made.
Preferably, bacteriostatic agent is nano silver.
Preferably, expanding material is microcrystalline cellulose, one of starch and povidone or a variety of.
Preferably, pH indicator is one of titan yellow, crystal violet or ethyl violet.
Preferably, hygroscopic agent CaCl2, glycerol, CaSO4One of.
The preparation method of medical antibacterial calcium lime, steps are as follows:
Step 1 is by Ca (OH)2, NaOH, hygroscopic agent, bacteriostatic agent and expanding material be added to mixing tank and stir and evenly mix, then plus Continue stirring to as soft material shape after entering pH indicator and water；
Shaggy short bar structure is made in soft material extrusion forming by step 2；
Short bar structure drying and shaping is obtained medical antibacterial calcium lime by step 3 after screening.
Preferably, the surface of short bar structure is covered with hemispherical groove in step 2, and stub height is 0.5-1cm, diameter 0.3-0.5cm。
Preferably, drying temperature is 90-120 DEG C in step 3, and it is 10-15% that short bar structure, which is dried to water content,.
It can effectively inhibit flora in ventilator numerous the advantages and positive effects of the present invention are: increasing bacteriostatic agent It grows, keeps the breathing environment of sterile clean；Calcium lime can absorb the heat in patient's exhaled gas, avoid closing circulating exhale Thermal accumlation during suction, so that patient temperature rises；Club shaped structure full of hemispherical groove can increase CO2Absorbing surface Product improves assimilation effect；Larger-size club shaped structure can reduce the formation of dust, to be lowered into the powder of respiratory tract Dirt.
Specific embodiment
It explains below to one embodiment of the present of invention.
