The purpose of this utility model is to overcome the deficiencies in the prior art part, and a kind of conventional oxygen therapy electronics warming and wetting apparatus is provided, and it is equipped with custom circuit by single-chip microcomputer and controls, and can carry out temperature and humidity automatically to oxygen and regulate.
The purpose of this utility model is achieved in that it comprises air inlet pipe, escape pipe, heating and moistening tank, control circuit, heating and moistening tank one side is fixed with thermal insulation layer, refrigeration cassette successively, the refrigeration cassette opposite side is bonded with semiconductor chilling plate, radiator successively, the radiator opposite side is fixed with fan, control circuit shell successively, and the control circuit device is loaded in the control circuit shell; Heating and moistening tank top is provided with air inlet and gas outlet, and air inlet is connected with air inlet pipe, and the gas outlet is connected with radiating tube; The refrigeration cassette top is provided with air inlet and gas outlet, and air inlet is connected with the radiating tube other end, and the gas outlet is connected with escape pipe, and the refrigeration cassette below is communicated with water leg; The nearly nose of escape pipe is equipped with temperature sensor; BCD dial-up dish is installed in the control circuit, and the P1.0-P1.3 interface of the 80C31 single-chip microcomputer in dial-up dish and the control circuit links to each other.
Compared with prior art, advantage of the present utility model is rational in infrastructure, can set oxygen temperature as required, and adjusts automatically, oxygen temperature control accuracy height, and error is below 1 ℃, and scope is between 21 ℃-36 ℃, and the oxygen relative humidity is more than 90%.The heating and moistening tank can be sterilized voluntarily during work, and is easy to use, safe and reliable.
The explanation of accompanying drawing drawing:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a circuit control block diagram of the present utility model.
Below in conjunction with drawings and Examples in detail this utility model is described in detail.
This utility model comprises air inlet pipe (15), escape pipe (8), heating and moistening tank (1) and control circuit, heating and moistening groove (1) one side is fixed with thermal insulation layer (2), refrigeration cassette (16) successively, refrigeration cassette (16) opposite side is bonded with semiconductor chilling plate (4), radiator (5) successively, radiator (5) opposite side is fixed with fan (6), control circuit shell (7) successively, and the control circuit device is loaded in the control circuit shell (7); Heating and moistening tank (1) top is provided with air inlet (14) and gas outlet (13), and air inlet (14) is connected with air inlet pipe (15), and gas outlet (13) are connected with radiating tube (12); Refrigeration cassette (16) top is provided with air inlet (11) and is connected with radiating tube (12) other end with gas outlet (10) air inlet (11), and gas outlet (10) are connected with escape pipe (8), and refrigeration cassette (16) below is communicated with water leg (3); The nearly nose of escape pipe (8) is equipped with temperature sensor (9); BCD dial-up dish is installed in the control circuit, and the P1.0-P1.3 interface of the 80C31 single-chip microcomputer in dial-up dish and the control circuit links to each other.
Scribble Electric radiant Heating Film on heating and moistening tank of the present utility model (1) inner bottom, Electric radiant Heating Film is the product of Shanghai industries under Ministry of the Second Light Industry Office for Scientific and Technical Information, and it is connected with the power supply of control circuit.Main control system adopts the 80C31 single-chip microcomputer, by 74LS397 decoder, 28C64 memorizer, links to each other with temperature sensor (9) after ADC8031 analog digital conversion and temperature voltage conversion.Control circuit all adopts universal standard circuit, cooling piece is crisscross arranged in the refrigeration cassette (16), bonding between it and semiconductor chilling plate (4), radiator (5) with heat-conducting silicone grease, semiconductor chilling plate (4) adopts the product of Chongwen District, Beijing semiconductor cooling device factory, radiator (5) adopts standard component, and fan (6) is the instrument fan.Semiconductor refrigerating (4) is communicated with power supply with fan (6) wiring is in parallel.
When this utility model uses, in heating and moistening tank (1), add an amount of water earlier, energized, electricity dial-up dish input design temperature, because just beginning oxygen is lower than design temperature, Electric radiant Heating Film gets electric work, and semiconductor chilling plate (4) and fan (6) are closed, and oxygen is supplied with patient by heating and moistening tank (1), radiator (5) refrigeration cassette (16), escape pipe (8); Temperature sensor (9) can be transformed into voltage signal with temperature signal and send into control circuit, the displays temperature value compares sampled value and setting value, on the one hand when sampled value is higher than setting value on the one hand, control circuit cuts out Electric radiant Heating Film, starts semiconductor chilling plate (4) and fan (6); When oxygen temperature drops to when being lower than before 1 ℃ of the setting value, Electric radiant Heating Film reheats, and makes oxygen temperature rise.Oxygen temperature floats in 1 ℃ of scope of setting value.During operate as normal, the water temperature in the heating and moistening tank (1) can reach 60-80 ℃, realizes the sterilization voluntarily to heating and moistening tank (1), after oxygen flows out from heating and moistening tank (1) simultaneously, handles through cooling again, and its relative humidity increases, and can reach more than 90%.When the water level in oxygen temperature and the heating and moistening tank (1) exceeds standard, but equal security alarm.
