Description
Technical field
This utility model patent relates to hygiene medical treatment instrument making art, develops a kind of monitoring device hemorrhage for internal arteriovenous fistula in hemodialysis process specifically.
Background technology
Hemodialysis (Hemodialysis) is the one of blood purification technology, is mainly used in the treatment of patient with end stage renal disease.China is hemodialysis demand big country, and within 2011, hemodialysis number accounts for 7.4% of the whole world.2012, Chinese patient with end stage renal disease about had 2,000,000 people.Along with the progressively expansion of China's medical insurance coverage rate at different levels, the patient numbers that Chinese patient with end stage renal disease accepts hemodialysis will significantly rise.
Vascular access is the basic guarantee carrying out hemodialysis smoothly.Vascular access can be divided into permanent vascular access and provisional vascular access.Internal arteriovenous fistula (arteriovenousfistula, AVF) is coincide at patient's radial artery and vein blood vessel close with it, and arteriovenous shunt forms internal fistula, makes venectasia arterial revascularization.During hemodialysis, the vein of arterial revascularization selects 2 punctures (being respectively vein end and arterial end), the blood flow [hemodialysis internal fistula punctures, Fig. 1] of more than 200ml/ minute can be ensured.
Hemorrhage the referring to of internal fistula is displaced to outside lumen of vessels in hemodialysis medium-sized artery or venipuncture needle, causes hemorrhage.Its main harm comprises: (1) hemorrhagic shock causes death; (2) increase the weight of renal anemia; (3) increase infection risk; (4) increase conflict between doctors and patients.Internal-fistula needle slippage is mainly seen in: (1) old dementia patients, cannot ensure the limb brake that punctures; (2) internal arteriovenous fistula surrounding tissue relaxes, the patient that internal-fistula needle fixedly has difficulties; (3) the patient of the vascular conditions such as diabetes and hypertension difference (blood vessel wall is thin and crisp).Accelerate and diabetes with social senilization's process, the rising year by year of hypertension chronic diseases incidence rate, internal-fistula needle displacement incidence rate has increase trend.
At present, the hemorrhage monitoring of internal fistula mainly contains 2 kinds of methods, and all there is certain defect: (1) hemodialysis nurse timing inspection, checks position and the local circumstance of puncture needle.The method cannot realize monitoring continuously and labor intensive; (2) puncture needle skids off outside blood vessel completely, and dialysis machine pressure monitor sensed pressure is abnormal, machine alarm.The method sensitivity is not good enough.Only have puncture needle to be displaced to outside blood vessel completely, and when causing enough pressure changes, machine is just reported to the police.And before puncture needle departs from lumen of vessels completely, internal fistula puncture place may have hemorrhage on a small quantity, but dialysis machine pressure monitor can not and alarm.Therefore, in clinical practice in the urgent need to the hemorrhage monitoring device of a kind of sensitive internal fistula.
Summary of the invention
The object of this utility model patent is a kind of monitoring device hemorrhage for internal fistula in hemodialysis process of exploitation, thus Timeliness coverage internal fistula is hemorrhage, reduces the hemorrhage complication brought.
For achieving the above object, we devise a kind of monitoring device hemorrhage for internal fistula in hemodialysis process, it is characterized in that, by diaphragm type button exploring electrode, plug-in type Multi-way connector and alarm generator three part are formed, described diaphragm type button exploring electrode is fixed on the point of puncture place of internal-fistula needle, and with plug-in type Multi-way connector, diaphragm type button exploring electrode is connected with alarm generator, thus formation alarm circuit, blood self-conductive is utilized to realize alarm detection, when internal fistula puncture place is hemorrhage, blood touches the detector electrodes in diaphragm type button exploring electrode, by plug-in type Multi-way connector trigger alarm generator.
Described diaphragm type button exploring electrode is made up of three-decker, ground floor is hydrophilic material, be directly fixed on the point of puncture of internal-fistula needle, the second layer is button exploring electrode, third layer is hydrophobic material layer, for closed exploring electrode, blood soaks hydrophilic material and arrives detector electrodes, will export by trigger alarm.
Alarm generator, adopts the buzzer sounding movement be made up of button cell and buzzer.
Described plug-in type Multi-way connector, is provided with three group interfaces, and first and second group interface connects vein end and arterial end detecting electrode respectively, and the 3rd group interface connects alarm generator.
This utility model is an alarm device that can connect that in monitoring of blood dialysis, internal fistula is hemorrhage, and structure is simple, and easy to use, warning sensitivity is good.

Detailed description of the invention
Now by reference to the accompanying drawings the technical solution of the utility model is further elaborated, believes it is clearly for a person skilled in the art.
As shown in Figure 1, be existing hemodialysis puncture of internal arteriovenous fistula schematic diagram, and the hemorrhage monitoring device of the internal fistula of this enforcement directly superpose and is applicable in this dialysis apparatus, specifically:
As shown in Figure 5, the monitoring device that internal fistula is hemorrhage, is made up of diaphragm type button exploring electrode, plug-in type Multi-way connector and alarm generator three part, wherein:
Described diaphragm type button exploring electrode, as shown in Figure 2, adopt primary sterilization product, every plate electrode is made up of three-decker, and ground floor is hydrophilic material, be directly fixed on the point of puncture of internal-fistula needle, the second layer is button exploring electrode, and third layer is hydrophobic material layer, for closed exploring electrode, blood soaks hydrophilic material and arrives detector electrodes, will export by trigger alarm.
