Technical field
This utility model relates to technical field of medical instruments, particularly a kind of internal fistula monitoring device.
Background technology
Internal arteriovenous fistula is a kind of minor operation of vascular anastomosis, 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 can provide sufficient blood, for the adequacy of dialysis treatment provides safeguard for hemodialysis.Internal arteriovenous fistula is the vascular access that Maintenance Hemodialysis Patients is commonly used, fully (200 ~ 300ml/min), infection chance are few to have safety, blood flow, the use of general internal fistula can maintain 4 ~ 5 years, do not affect patient daily life, be easy to the advantages such as puncture.
But after internal arteriovenous fistula is formed, the arterial blood that pressure is higher can form turbulent flow through the lower lateral vein of excess pressure and produce fast trembles or noise.The mark of successful surgery is that Postoperative Intravenous can touch and trembles, and hears vascular murmur.Early postoperation repeatedly should check and tremble and noise, so that early discovery thrombosis processes in time, if find to tremble or noise extinction time shorter (being less than 6 hours), then the feasible internal arteriovenous fistula thromboembolism treatment of patient, has an opportunity again to circulate blood vessel.Whether successful, that whether blood vessel the is unobstructed method of monitoring operation conventional in current clinical course is that doctor uses auscultation with stethoscope vascular murmur, but every day, the number of times of doctor's auscultation was limited, and the number of times of Discharged patients auscultation is voluntarily more limited, and also have most of patient can auscultation.
In sum, be necessary to design that a kind of structure is simple, easy to operate, general patient also can judge the whether normal internal fistula monitoring device of internal fistula, to solve the problem.
Utility model content
In view of this, the technical problems to be solved in the utility model is to provide a kind of internal fistula monitoring device, and structure is simple, and be easy to operation, patient oneself can judge that whether internal fistula is normal.
This utility model is solved the problems of the technologies described above by following technological means:

The beneficial effects of the utility model: internal fistula monitoring device of the present utility model comprises bracer, described bracer is provided with monitoring device, described monitoring device comprises sensor, processor and output device, described sensor, processor are connected in turn with output device, described processor comprises pre-amplification circuit, filter circuit and power amplification circuit, and described pre-amplification circuit, filter circuit are connected in turn with power amplification circuit.Bracer is provided with monitoring device, and monitoring device exports after the noise monitored or the signal that trembles are carried out power amplification process again after amplification, filtering, doctor or patient can directly be heard, judges that whether internal arteriovenous fistula is normal.Bracer is double-decker, is arranged on by monitoring device between bracer skin and internal layer, can prevents monitoring device from encountering patient's internal fistula position, cause hemorrhage or uncomfortable.Be provided with protection cylinder in bracer outside, be also convenient to patient while playing a protective role and going out also to monitor internal fistula anastomotic stoma.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, this utility model is further described.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structured flowchart of monitoring device of the present utility model.
Detailed description of the invention
Below with reference to accompanying drawing, this utility model is described in detail, as Fig. 1, shown in 2:
Internal fistula monitoring device of the present utility model, comprise bracer 1, described bracer 1 is provided with monitoring device 2, described monitoring device 2 comprises sensor 21, processor 22 and output device 23, described sensor 21, processor 22 are connected in turn with output device 23, described processor 22 comprises pre-amplification circuit 221, filter circuit 222 and power amplification circuit 223, and described pre-amplification circuit 221, filter circuit 222 are connected in turn with power amplification circuit 223.The pressure signal collected is converted to the signal of telecommunication by sensor 21, through enlarge leadingly, filtering and power amplification process, namely can export.Monitoring device established by bracer, monitoring device by Sensor monitoring to noise or tremble to export after amplifying, carrying out power amplification process again after filtering, doctor or patient can directly be heard, judge that whether internal arteriovenous fistula normal.
As the further improvement of technique scheme, described sensor 21 is piezoelectric film sensor, and piezoelectric film sensor, as a kind of type of dynamic strain sensor, is applicable to the vital signs monitor being applied to human skin or implant into body inside very much.Piezoelectric membrane is very responsive to dynamic stress, and piezoelectric membrane is very thin, light weight, very soft, can non-active operation, can detect the trickle signal that trembles, and piezoelectric membrane is extremely durable, can stand the bending and vibration of millions of times.
