Description
Technical field
This utility model relates to a kind of transfusion liquid level detection system, more specifically says so and utilizes optical sensor to detect the system of transfusion liquid level.
Background technology
Transfusion is a therapeutic modality common in the hospital, all has every day many patients to receive infusion treatment.Infusion apparatus commonly used at present needs families of patients or medical personnel to observe when work, can cause " blood back " or other adverse consequencess otherwise can not in time stop transfusion when medicinal liquid uses up, and brings misery and causes malpractice to patient.
Present infusion alarm adopt usually electrode method, optical detection, drop count technique and check weighing method detect residual liquid level in the infusion bottle.The electrode method utilizes the variation of liquid conduction to detect the medicinal liquid surplus by implant electrode in infusion bottle.Optical detection is put into a buoy in infusion bottle, when liquid level was reduced to assign thresholds, buoy blocking light path caused warning.These two kinds of methods all need to allow foreign body directly contact with medicinal liquid, easily medicinal liquid are polluted, and influence therapeutic effect.Drop technology law and check weighing method precision are not high, and can not adapt to the infusion bottle or the transfusion bag of different sizes, specification automatically, and versatility is bad.Also have a kind of optical detection that induction apparatus is set on tube for transfusion in addition, have only when the infusion bottle inner liquid medicine and use up, liquid level just can be sent warning after having dropped in the tube for transfusion, for the patient brings a lot of inconveniences.
The utility model content
Technical problem to be solved in the utility model provides a kind of transfusion liquid level detection system based on optical sensor, and it can monitor the current liquid level of a plurality of infusion bottles in real time.
For solving the problems of the technologies described above, this is implemented novel a kind of transfusion liquid level detection system based on optical sensor and comprises liquid level detection device and remote monitoring platform, described liquid level detection device is fixed on the infusion bottle by fixture, comprises the power module, luminous lamp tube, light intensity induction apparatus, control module, motor and the radio receiving transmitting module that are used to power; Wherein the vertical direction in a side of liquid level detection device is provided with rail plate, and described light intensity induction apparatus is arranged on the rail plate; Described motor is arranged on the vertical top of rail plate, slides on rail plate by conveyer belt traction light intensity induction apparatus; Described luminous lamp tube is arranged on the opposite side and the corresponding position of rail plate of liquid level detection device; Described remote monitoring platform is a computer terminal that is provided with monitoring software.
As further improvement of the utility model, described light intensity induction apparatus adopts the GaAsP light sensitive diode as photo-sensitive cell;
As further improvement of the utility model, described control module adopts MSP430 as acp chip;
As further improvement of the utility model, described fixture is an elastic brace web, described liquid level detection device can be fixed on the infusion bottle of different size;
As further improvement of the utility model, described luminous lamp tube is a plurality of light emitting diode parallel connections, arranges into elongate in shape.
Adopt said structure, monitor the current liquid level position of a plurality of infusion bottles in real time by a remote monitoring platform, change the working method that traditional medical personnel make an inspection tour back and forth, significantly reduce medical personnel's workload, simultaneously, respond to liquid level by light intensity signal, need not to contact medicinal liquid, avoid causing harmful effect because of polluting medicinal liquid.

Description of reference numerals: 1 radio receiving transmitting module, 2 control modules, 3 power modules, 4 light intensity induction apparatuss, 5 fixtures, 6 luminous lamp tubes, 7 motors, 8 rail plates.
The specific embodiment
From Fig. 1, Fig. 2, Fig. 3 as can be known, liquid level detection device is fixed on the infusion bottle by fixture 5, fixture 5 uses the high resiliency elastic cord to make, can be securely on the infusion bottle attached to different size with liquid level detection device, power module 3 uses No. 5 batteries of 2 joints, be control module 2, luminous lamp tube 6, light intensity induction apparatus 4, motor 7 and radio receiving transmitting module 1 power supply, the vertical direction of one side of liquid level detection device is provided with rail plate 8, light intensity induction apparatus 4 is arranged on the rail plate 8, opposite side and rail plate 8 corresponding positions at liquid level detection device are provided with luminous lamp tube 6, luminous lamp tube 6 adopts a plurality of light emitting diode parallel connections, arrange into elongate in shape, the light that luminous lamp tube 6 sends sees through infusion bottle and is radiated on the light intensity induction apparatus 4, for it provides lighting source.Light intensity induction apparatus 4 uses the GaAsP light sensitive diode as photo-sensitive cell, and this light sensitive diode response speed is fast, and spectral sensitivity characteristic need not add the ultraviolet cutoff light filter near visible light.Light intensity induction apparatus 4 moves to the bottom from the top at the traction lower edge of motor 7 rail plate 8.After light intensity induction apparatus 4 moved to the bottom, control module 2 sent reverse movement directive, makes it be moved back into the top fast, restarted to move the end of to from the top.Light intensity induction apparatus 4 is transferred to control module 2 with the light intensity of sensing simultaneously in coming and going the process that moves.After the light intensity induction apparatus was finished moving process, control module 2 calculated current liquid level position in the infusion bottle according to the light intensity signal change curve of this process record, by radio receiving transmitting module 1 liquid level position was sent to remote monitoring platform then.
Fig. 5 is the remote monitoring platform program interface figure of this utility model embodiment, remote monitoring platform is a computer terminal that is provided with monitoring software, this computer terminal is arranged in the medical personnel office on duty, by accepting the liquid level information that radio receiving transmitting module 1 sends a plurality of liquid level detection devices, and it is presented on the software interface, automatically send warning message when finding that certain infusion bottle liquid level is crossed when hanging down, realized good man computer interface.
This utility model is not limited to above-mentioned embodiment.Should be pointed out that for this area those skilled in the art, under the prerequisite that does not break away from this utility model principle, can also make some distortion and improvement, all belong to protection domain of the present utility model.
