Abstract
The utility model relates to a wristband type monitoring device for an internal arteriovenous fistula. The wristband type monitoring device comprises a wristband; the wristband is provided with a sound detector, a central processor, a display screen and a buzzer; the sound detector is arranged on the inner side of the wristband and used for being closely attached to the skin; the output end of the sound detector is connected with the input end of the central processor; the output end of the central processor is connected with the display screen and the buzzer; the display screen is installed on the outer side of the waistband; the waistband is further provided with a battery used for supplying power to the sound detector, the central processor, the display screen and the buzzer. According to the wristband type monitoring device for the internal arteriovenous fistula, the detachable waistband is adopted, and the degree of tightness can be freely adjusted; after a patient wears the wristband type monitoring device, the sound detector can be closely attached to an internal arteriovenous fistula part and collect the sound of blood flow at the internal arteriovenous fistula part for monitoring the operating state of the internal arteriovenous fistula in real time; when the internal arteriovenous fistula is blocked, a prompt can be given through the display screen, and the buzzer buzzes for acousto-optical warning to remind that a wearer and nursing staff should take measures so that the smoothness of the internal arteriovenous fistula can be guaranteed.
Description
Technical field
This utility model relates to a kind of wrist protection type internal arteriovenous fistula watch-dog, belongs to technical field of medical instruments.
Background technology
Internal arteriovenous fistula refers to a kind of minor operation of vascular anastomosis, forearm is done to one near the tremulous pulse at wrist position and contiguous vein and sew up, and the arterial blood that makes flowing in the vein after coincideing, forms an internal arteriovenous fistula.The blood vessel of internal arteriovenous fistula can provide sufficient blood for hemodialysis, for the adequacy of dialysis treatment provides safeguard, is the life line of accepting dialysis treatment patient.Use internal arteriovenous fistula as the following advantage of having of dialysis treatment:
1. internal arteriovenous fistula is the conventional vascular access of Maintenance Hemodialysis Patients
2. internal arteriovenous fistula is the safest vascular access of current hemodialysis patients, and its wound is little, little to effect of heart function, service time long, be easy to puncture.
3. fully (200 ~ 300ml/min), infection rate are low for blood flow.
4. the use of internal fistula can maintain 4～5 years.
5. do not affect patient's daily life.
But the factors such as point of puncture pressing time is long because vascular anatomy is abnormal, after hemodialysis hypotension state, dialysis likely can be blocked in the use procedure of internal fistula.Have bibliographical information internal fistula use in two years at first, the incidence rate of its obstruction is 30%～40%, the time that research shows to occur Fistula obstruction, blocking incidence rate was 22.4% with common in initial 3 years.Therefore within initial several years, want especially the generation of close observation and pre-anti-blocking.But following introduction of existing daily monitoring nursing:
1. internal fistula art limb can not bear a heavy burden, and does not oppress in bed art limb, can, by soft bolster Rhizoma Atractylodis Macrocephalae limb, promote venous blood flow.
2. note the protection to internal fistula art limb, avoid collision, prevent injured.
3. coat-sleeve wants pine to avoid greatly tension.
4. internal fistula art limb can not be taken blood pressure, all vein treatments and blood drawing.
Every day Monitoring of blood pressure, take depressor on time, prevent that hypertension from avoiding hypotensive generation.
6. keep the clean of internal fistula art limb, clean local every day, prevention infection.
7. within postoperative 10 days, start to be strong fistula behaviour.
8. self-monitoring internal fistula anastomotic stoma has atremia and auscultation vascular murmur.
In patient's use procedure, after internal fistula obstruction treated, patient need to re-start conduit and inserts as provisional alternative pipeline, has increased patient's misery, and financial burden increases the weight of, and has more increased the possibility of catheter infections.According to obstruction and the obturation of research internal fistula, it is a progressive process, if can accomplish that early discovery early treatment can avoid completely, patient in regular maintenance, relies on internal fistula to tremble and vascular murmur is monitored the whether unobstructed of internal fistula, but patient can only the daily medical personnel of Herba Alii fistulosi propaganda and education's knowledge obtain the monitoring standard of relevant internal fistula, lack individual, science, dynamic, successional observation.
Utility model content
The technical problems to be solved in the utility model is: propose a kind of intellectuality and wear internal arteriovenous fistula watch-dog easily.
This utility model is that the technical scheme that solves the problems of the technologies described above proposition is: a kind of wrist protection type internal arteriovenous fistula watch-dog, comprise wrist strap, and described wrist strap is provided with sound-detection gear, central processing unit, display screen and buzzer; Described sound-detection gear is located at described wrist strap inner side for being close to skin, and the outfan of described sound-detection gear connects the input that described central processing unit connects, and the outfan of described central processing unit connects described display screen and buzzer; Described display screen is arranged on described wrist strap outside; On described wrist strap, also there is a battery that is used to described sound-detection gear, central processing unit, display screen and buzzer power supply.
This utility model further improves and is: between described sound-detection gear and described central processing unit, be in series with amplifier.
This utility model further improves and is: described wrist strap is provided with VELCRO, connect a kind of in buckle, Magnetic hasp or elastic cord.
The beneficial effect that this utility model brings is:
Wrist protection type internal arteriovenous fistula watch-dog of the present utility model, adopt dismountable wrist protection type, elasticity is arbitrarily adjusted, after patient wear, sound collector can be close to internal fistula position, gather the sound of internal fistula position blood flow, be used for monitoring in real time the duty of internal fistula, when internal fistula obstruction treated, can can point out by display screen, and the warning of acousto-optic is carried out in buzzer buzzing, prompting user and nursing staff take measures, to ensure the unobstructed of internal fistula.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is this utility model example structure schematic diagram.
Number in the figure is schematically as follows: 1-central processing unit, 2-display screen, 3-buzzer, 4-battery, 5-wrist strap, 6-sound-detection gear.
The specific embodiment
Embodiment
The wrist protection type internal arteriovenous fistula watch-dog of the present embodiment as shown in Figure 1, comprises wrist strap 5, and wrist strap 5 is provided with sound-detection gear 6, central processing unit 1, display screen 2 and buzzer 3; Sound-detection gear 6 is located at wrist strap 5 inner sides for being close to skin, and the outfan of sound-detection gear 6 connects the input that central processing unit 1 connects, and the outfan of central processing unit 1 connects display screen 2 and buzzer 3; Display screen 2 is arranged on wrist strap 5 outsides; On wrist strap 5, also there is a battery 4 that is used to sound-detection gear 6, central processing unit 1, display screen 2 and buzzer 3 power supplies.
