Description

The digital multifunctional infusion monitor

Technical field

This utility model relates to a kind of medical apparatus and instruments, the monitor device of specifically a kind of ward venous transfusion.

Background technology

Venous transfusion is one of the most frequently used treatment means of hospital ward.At present, the patient is complete in nurse, family members or patient oneself observation to dose in the infusion bottle in infusion process, in case need in time to change or end treatment near dripping off.By in part hospital investigation, a lot of patients can't sleep in the process of transfusion under the situation that does not have the household to accompany at all, fear that liquid walks sky, infuse at every turn and feel very tired.Even also occur observing untimely sometimes, cause bottle interior liquid to drip off fully, the blood of venous patient will flow in the syringe needle nylon tubule under the effect of blood pressure even solidify, continue fluid infusion as need, must seek vein again punctures once again, bring misery to patient, also increased nurse's work.

Recently, a lot of monitoring infusion devices have appearred, as the patent No. be 95219124.5 and the patent No. be 96115783.6 etc., its main common feature be can in the process of transfusion, detect automatically drip speed, control is dripped speed, is realized a warning function.But all there is not the temperature monitoring unit, can't monitor out the abnormal response of patient in infusion process (as occurring " infusion reaction " in the infusion process easily, show as the fluctuation of body temperature), simultaneously along with development of wireless communication devices such as bluetooth, GPRS, provide possibility for the monitor networking becomes Hospital Sickroom Guardian System, and former monitor is not provided with communications processor element and networked interface.

The utility model content

The purpose of this utility model provides a kind of more perfect, reliable digital multifunctional infusion monitor.

This utility model is made up of master-slave mode CPU processing unit, a fast detecting sensor, flow control valve, motor, temperature check pick off, LCDs, numeric keypad, communication module and networked communication interface etc.

More than various functional units be integrated on the circuit board of monitor enclosure interior, many microprocessing units adopt I ²The C bus makes up, and finishes information gathering, processing, transmission, control and management to infusion process.Dripping fast detecting unit is made up of polynary infrared transmitter and polynary infrared remote receiver, it is installed on the housing China ink Fei Shi tube seat sidewall, form multichannel infrared signal monitoring channel, finish signals collecting, anti-interference process by software, compare with existing single channel infrared signal monitoring, have more reliable advantage.The circuit part of display unit is integrated on the circuit board, and display screen is contained on the shell of monitor surface of shell, and button also is installed in below the surface of shell display screen, and the unitary temperature sensor of temperature monitoring is drawn by lead.

It is to be absorbed or reflect by drop by the infrared energy that infrared transmitter sends that of the present utility model speed detects, and causes the decay of the infrared energy of infrared remote receiver reception to form fluctuation signal, obtains dripping a fast signal by microprocessing unit; Control signal can be transferred to the motor of control execution unit by key input signal by microprocessing unit, realize dripping the control of speed; The detected temperature signal of temperature sensor can be shown in temperature signal on the display screen by microprocessing unit.

The built-in optional communication interface of this utility model is easy to carry out the function expansion; And but networking realizes remote monitoring, management to many monitors.

The effective effect of this utility model is that the speed control system of dripping is more reliable, anti-interference stronger, and functional configuration is more perfect, flexible, uses more conveniently, simple, assurance infusion treatment process safety, carries out smoothly, compared with similar products, the utlity model has following advantage;

The first, have abundant Presentation Function, be convenient to inquire about various Monitoring Data.

The second, increased temperature detecting unit, realized real-time monitoring, also can when not infusing, use separately patient temperature.

Three, perfect numeral keys imports, and can set inquiry to parameter quickly and easily.

Four, built-in communication interface can realize wireless or wired networking, realizes telecommunication network management and control, alleviates medical personnel's labor intensity greatly.

The specific embodiment

Below in conjunction with accompanying drawing, this utility model is further specified as follows: as Fig. 1, the black Fei Shi pipe of one-time infusion tube is contained in the groove the inside of monitor housing, the drop detection pick off is contained on the sidewall of groove, as Fig. 2, circuit board, motor 8 flow control valves 7 are contained in the housing the inside, and body temperature trans 6 is connected with the CPU processing unit by lead 5.

When using this utility model, black Fei Shi pipe close is gone in the infusion monitor housing China ink Fei Shi tube seat, by just entering duty behind the monitor that presses switch to open, by being contained in infrared transmitter and the infrared absorber 1 on the housing China ink Fei Shi tube seat wall, can detect and drip speed, and the data that detect are reached treatment circuit 9, show by display screen 3 again; The form that temperature sensor 6 can be made paster be attached on health a part of patient with patient's temperature data real-time Transmission to processing unit 9 or display screen 3.By to numeric keypad 4 operations, can control dripping speed, control signal reaches processing unit by the communication data line, produces and controls signal to motor 8, and motor rotates with control flow valve 7, realizes dripping the control of speed.Complete machine electricity theory diagram such as Fig. 3.

Temperature detection of the present utility model is the method realization temperature survey by chip 12C508 control critesistor.Fig. 4 has shown the circuit structure diagram of 12C508 by critesistor RTMP detected temperatures signal.By writing down twice pair of known and unknown resistance resistance charging and the measuring and calculating of discharge time, thereby calculate resistance value and temperature value accordingly.In addition, temperature survey of the present utility model also can adopt contactless infrared measurement of temperature principle to measure temperature.
