Description

The medical oxygen taximeter

Technical field

The utility model relates to and is mainly used under hospital's concentrated oxygen supply or the steel cylinder oxygen supply condition timing and charging device in the patient in hospital oxygen uptake process.

Background technology:

Existing hospital only clocks with common timer in concentrated oxygen supply, and middle patient has a meal or other thing stops oxygen supply, can only tell doctor or nurse's record to reduce by the patient, it is inaccurate to clock like this, and often the patient is having complaints aspect the note expense, and the workload of hospital is also big.

Summary of the invention:

The purpose of this utility model is to overcome above-mentioned shortcoming, provide a kind of can Fare determined by travel time medical oxygen taximeter accurate, easy to use.

Technical characterictic:

Its groundwork principle of medical oxygen taximeter is as follows:

See Fig. 2, medical oxygen taximeter schematic block circuit diagram of the present utility model.The medical oxygen taximeter is characterized in that: little processing main control circuit input end connects keyboard, stabilized voltage supply, power backup battery, rest button, sensor respectively, and little processing main control circuit output terminal connects display, external power pilot lamp respectively.

Described medical oxygen taximeter is characterized in that: little processing main control circuit adopts integrated circuit 89C1051, and keyboard adopts 4 * 4 keyboards, and display adopts LCD display, and stabilized voltage supply adopts the MC7805 integrated regulator.

Advantage: see Fig. 1, medical oxygen taximeter fundamental diagram, the oxygen channel interface is connected with oxygen flow meter, patient's oxygen uptake pipeline is connected with oxygen flow meter, sensor is connected with oxygen flow meter, the signal of sensor is through after the signal Processing, demonstrates cumulative time, the accumulative total expense of oxygen uptake by display, and system password sets in advance in this medical oxygen taximeter.Medical oxygen taximeter timing note is taken accurately, intuitive display, easy to use.

Embodiment:

See Fig. 4: medical oxygen taximeter guidance panel figure of the present utility model, the taximeter guidance panel, adopt 16 keying input information, can store three different patients' oxygen time and expense situation, display 10 adopts 8 bit digital to add the LCD screen of radix point and colon; The longest demonstration time of taximeter is 9999 hours 59 minutes; The oxygen uptake expense show at most 9999 yuan 99 minutes.Show oxygen time (or oxygen uptake expense) during work, the expense (or oxygen time) that can inquire about oxygen uptake simultaneously;

Can carry out patient user by the input system password and be provided with and information deletion, password also can be changed at any time by corpsman,hospital's control.The built-in DC charging powered battery of medical oxygen taximeter, while distribution source adapter, the 220 volts of external power supplys power supplies of can pegging graft.

See Fig. 3: the sensor axis among Fig. 2 is to cut-open view.Sensor comprises: shell 6 is fixed on outside the own hexagonal (hexagon)nut 1 of suspended body flowmeter, lengthening main shaft 3 is fixed on the suspended body flowmeter main shaft 2, rotary brush 4 is fixed on the lengthening main shaft 3, fixed electorde 5 is enclosed within outside the lengthening main shaft 3, cover plate 7 is fixed on shell 6 outer ends, and knob 8 is fixed on the outer end of lengthening main shaft 3.

Each parts Action Specification of sensor:

It is own that hexagonal (hexagon)nut 1, the oxygen flow among Fig. 1 are counted suspended body flowmeter;

It is own that main shaft 2, the oxygen flow among Fig. 1 are counted suspended body flowmeter;

Lengthening main shaft 3, with the main shaft of suspended body flowmeter lengthening itself, by the rotation of main shaft, the realization flowmeter open and close operation;

Rotary brush 4 and fixed electorde 5, during by main shaft 2 rotations, rotary brush 4 rotates, and connection and cut-out fixed electorde 5 are converted into electric signal with the mechanical rotation signal, when realizing opening and closing flow, can in time charge to electrical equipment and partly provide electric signal;

Shell 6 and cover plate 7,7 protections of the shell 6 of sensor and cover plate and fixation;

Knob 8 by operation knob 8, is realized main shaft 2 rotations, finishes the effect of opening and closing of oxygen flow meter A among Fig. 1.When not oxygen uptake of patient, by doctor or patient's operation knob 8, oxygen flow meter A is closed, while sensor 5 is passed to microprocessor governor circuit MCU with the signal of brush 4 and fixed electorde 5 and is carried out signal Processing.

See Fig. 2 and Fig. 5, the explanation of medical oxygen taximeter electrical work principle:

Sensor detects the oxygen flow state in real time, and gives microprocessor governor circuit MCU in real time with this information;

The keyboard matrix of 4 * 4=16 is given microprocessor governor circuit MCU with operator's true-time operation instruction generating run sign indicating number;

Power module is civil power (220V/50Hz), the DC voltage that the system that is converted to is required, the power backup battery is outside under the power cut-off situation, automatically uninterruptedly in real time to system's power supply greater than 48 hours, meanwhile, power backup indication light emitting diode (red) lamp is bright;
