The utility model discloses a set up the detection that ultrasonic transducer carries out the internal arteriovenous fistula blood flow volume on a wrist strap, have small, portability and wearing, can directly obtain the advantage of data.
Description
Technical field
This utility model relates to medical monitoring equipment research field, particularly one wearable internal arteriovenous fistula blood flow monitor.
Background technology
Arteriovenous internal fistula formation is a kind of minor operation of vascular anastomosis, specifically by the tremulous pulse of forearm near wrist position and vein work one stitching of vicinity, makes to flow in the vein after coincideing arterial blood, forms an internal arteriovenous fistula.The blood vessel of internal arteriovenous fistula needs for hemodialysis provides sufficient blood, for the adequacy of dialysis treatment provides safeguard.Internal fistula will meet that treatment is used, and its blood flow generally need reach 250-350ml/s, therefore needs the change of blood flow of monitoring internal fistula, finds that internal fistula blood flow is not enough early, and roughly locates the more serious position of blood flow retardance, carries out therapeutic intervention so that follow-up.
The blood flow checkout gear of current employing is based on electromagnetic measurement, infrared survey, impedance bioelectrical measurement, injection isotope measure, Nuclear Magnetic Resonance Measurement substantially, and other has wound property inspection etc.Up-to-date indirectly monitoring technology also comprises the laser vibration measurer of indirect inspection internal fistula pollex speed amplitude, and measures the sound-detection gear of internal fistula noise intensity.But above-mentioned detection device ubiquity instrument comparatively large (as B ultrasonic machine or MRI machine), the shortcoming such as have wound property, the data that obtain indirect.
Utility model content
The purpose of this utility model is that the shortcoming overcoming prior art is with not enough, a kind of wearable internal arteriovenous fistula blood flow monitor is provided, this monitor is wearable device, internal arteriovenous fistula blood flow can be measured in real time, visually, have that volume is little, portability and wearing, visual advantage.
The purpose of this utility model is realized by following technical scheme: wearable internal arteriovenous fistula blood flow monitor, and comprise wrist strap and monitoring device, described monitoring device is fixed on wrist strap; Described monitoring device comprises ultrasound probe, controller, display screen, sound and light alarm module, and described ultrasound probe is arranged on inside wrist strap, is close to side skin on arterial-venous fistula during use, and the outfan of ultrasound probe is connected with the input of controller; The outfan of controller is connected with display screen, sound and light alarm module respectively; Display screen is used for the blood flow showing the internal fistula collected in real time.
Preferably, described wrist strap adopts anti-anaphylaxis silica gel material, and its diameter is adjustable.Therefore independently can adjust according to user upper limb thickness, more convenient.
Further, with a snap close and several lockholes on described wrist strap, during monitoring, snap close is fixed therein in a lockhole.Thus realize the adjustable of wrist strap diameter.
Preferably, described ultrasound probe adopt diameter within 20mm, model is the sonac of UMT30.By this sensor, the frequency of more than 2MHz can be adopted accurately to locate and detect blood flow parameters.
Preferably, described sound and light alarm module comprises alarm lamp and buzzer, and the outlet sound mouth of alarm lamp and buzzer is all arranged on around display screen, and alarm lamp is connected with controller respectively with buzzer.
Compared with prior art, tool has the following advantages and beneficial effect this utility model:
1, this utility model by arranging the detection that ultrasound probe carries out internal arteriovenous fistula blood flow on a wrist strap, has that volume is little, portability and wearing, directly can obtain the advantage of data.
2, in this utility model, the diameter of wrist strap can carry out free adjustment according to the difference of patient's arm thickness, is convenient to promote.
3, be also provided with a display screen in this utility model, this display screen is used for showing the blood flow of the internal fistula collected in real time, can person easy to use and the real-time observation variable quantity of doctor.Also be provided with sound and light alarm module simultaneously, once blood flow occurs abnormal, then automatically remind, use more convenient, efficient.
Accompanying drawing explanation
Fig. 1 is the present embodiment cross-sectional view.
Fig. 2 is the Facad structure schematic diagram at display screen place in the present embodiment.
Wherein: 1-ultrasound probe, 2-controller, 3-display screen, 4-alarm lamp, 5-outlet sound mouth, 6-wrist strap.
Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, this utility model is described in further detail, but embodiment of the present utility model is not limited thereto.
Embodiment 1
As shown in Figure 1, the present embodiment wearable internal arteriovenous fistula blood flow monitor, comprises wrist strap 6 and a monitoring device, in use, is worn on by wrist strap on the arm of user, is used for measuring internal arteriovenous fistula blood flow in real time.
In the present embodiment, the outside framework of monitoring device, is fixed on wrist strap, is similar to common watch style.The structure of described monitoring device is see Fig. 1,2, specifically comprise ultrasound probe 1, controller 2, display screen 3, ultrasound probe, controller are all arranged in framework, ultrasound probe is arranged on inside wrist strap, be close to side skin on arterial-venous fistula during use, the outfan of ultrasound probe is connected with the input of controller.Display screen is arranged on the outside of framework, and the outfan of controller is connected with the input of display screen, and the blood flow of the internal fistula that ultrasound probe detects by controller shows on a display screen in real time.
In the present embodiment, monitoring device further comprises sound and light alarm module, and sound and light alarm module is specially alarm lamp 4 and buzzer, the two structure is see Fig. 2, alarm lamp is arranged on the top of display screen, and buzzer is arranged in the framework of monitoring device, and its outlet sound mouth 5 is arranged on the upper end of display screen.Alarm lamp is all connected with controller with buzzer.According to prior art, first can preset two threshold values in the controller, be respectively Low threshold and high threshold.In real time or the ultrasonic signal of timing acquiring ultrasound probe, ultrasonic signal is converted to numerical signal by the built-in chip of controller, once current value signal value is lower than Low threshold, then illustrate that current blood flow blocks, then send control signals to alarm lamp respectively and buzzer is externally reported to the police.Same, once current value signal value is higher than high threshold, then illustrate that current unusual blood flow is accelerated, then send control signals to alarm lamp respectively and buzzer is externally reported to the police.To intervene in time and medical check further.
Wrist strap in the present embodiment adopts anti-anaphylaxis silica gel material, and on wrist strap, being provided with a snap close and several lockholes, snap close is locked in different lockholes, then the diameter of wrist strap will be different, so go for measuring different patient, or the different parts of same patient is measured.When measuring the different parts of same patient, in conjunction with sound and light alarm module, repeatedly can shift one's position on arterial-venous fistula path, in case of blood flow retardance or the quickening of unusual blood flow can coarse localization.
Above-described embodiment is this utility model preferably embodiment; but embodiment of the present utility model is not restricted to the described embodiments; change, the modification done under other any does not deviate from spirit of the present utility model and principle, substitute, combine, simplify; all should be the substitute mode of equivalence, be included within protection domain of the present utility model.
