Description
Technical field
The present invention relates to a kind of analyzer, specifically a kind of intelligence internal arteriovenous fistula functional analysis instrument belongs to Medical Devices
Technical field.
Background technique
Currently, in world wide, there are about 1,500,000 End-stage renal disease patients using haemodialysis as renal replacement therapies side
Formula.U.S.'s KDOQI guideline recommendation is used using Autogenous arteriovenous internal fistula as long term vascular access for haemodialysis, is mentioned again within 2003
The principle of internal fistula the first " out ".Therefore internal fistula is considered as presently preferred vascular access.
Autogenous arteriovenous internal fistula plasty is on the basis of surgical operation, and the peripheral arterial and superficial for the patient that coincide are quiet
Arteries and veins, so that arterial blood flow to Superficial veins, blood flow needed for reaching haemodialysis requires and is convenient for vascular puncture, thus
Establish haemodialysis extracorporal circulatory system.With the extensive use of AVF, it is studied and is also continuously increased and gos deep into, at the same time internal fistula
There are the problem of also gradually highlight.Wherein early stage dysmaturity ratio is quite high.Because being hospitalized caused by vascular access stenosis and embolism
Number accounts for dialysis patient and is hospitalized the 15%~24% of total number of persons.Nephrology dept. of The People's Hospital of Peking University causes because of vascular access problem
Hospital day account for the 36% of total hospital day, the medical expense for solving vascular access reaches the 2O% of total hospitalization cost.Therefore,
An ideal vascular access how is maintained, extends it and effectively uses the time, reducing complication is that whole blood is net
Change medical staff and the common focus of attention of patient.
Under the current precisely background of medicine, clinical nursing practice model needs embody the intension precisely nursed completely, this
The emphasis of the new care mode of kind is able to the demand of identification patient, and unified standard is exactly the fortune of clinical nursing path
With.Clinical nursing path (Clinical Nursing Pathways, CNP) contains quality assurance, evidence-based doctor as one kind
, the diagnosis and treatment standardized method of holistic Nursing, continuous quality improvement.Clinical nursing path can optimize original process
And redesign, it is established that smooth service chaining integrates clinical guidelines and evidence during formulating clinical nursing path,
And clinical nursing activity path is made in the combination of the actual conditions of Personal Skills, clinical experience and patient.
Currently, clinically for the instrument inspection of internal fistula function, mainly passing through Color Doppler ultrasound guide checks sound
The case where arteries and veins arterial-venous fistula.It is lain on the back when patient's color ultrasound examination on bed board, the hand of patient is completely exposed, and lay flat outward
Expansion.When carrying out vascular test, the arteries and vein blood vessel of arm front end are checked using crosscutting and longitudinal sectional cooperation.Using
The blood flow direction of color Doppler ultrasonography technology patient, when observe vascular anastomosis or it is narrow when, be to hemadostewnosis
The internal diameter of place and adjacent position measures, and when monitoring the blood flow of patient's internal fistula, to obtain blood flow using arteria brachialis
Frequency.When detection, instrument probe will as far as possible with the perpendicular shape of skin surface, to prevent becoming larger for measurement error；When sampling
Entire lumen of vessels is covered, can prevent from ignoring the low velocity flow amount close to blood vessel wall site；Strength will be suitable for when firmly, prevent
Be pressurized to superficial vein, it is necessary to when can increase the dosage of couplant, help the angle for adjusting injection, be maintained at 45 °~
60 °, same position detection is multiple and is averaged.It is colored how general in terms of the monitoring of autologous vein internal arteriovenous fistula blood flow
Although accurate autologous vein internal arteriovenous fistula blood flow detection can't be carried out by strangling ultrasound, color Doppler is able to carry out
Whether there is or not abnormal responses in terms of iconography for dynamic observation, and the detection to blood flow is not carried out using the internal fistula of dialysis also, right
Whether explanation internal fistula is mature and causes internal fistula unsuccessfully whether there is or not unfavorable factor and has the meaning of directiveness.To autologous vein arteriovenous
The dialysis of internal fistula blood flow can determine the appearance of the complication such as Fistuk stenosis or thrombus, have directive significance to clinical treatment,
The incidence of internal fistula failure can be effectively reduced.It can quickly judge that autologous vein is dynamic by Color doppler ultrasound
The quality of vein internal fistula is capable of detecting when the symptoms such as thrombus, patch and anastomotic stricture with Color Doppler ultrasound, and blood
The formation of bolt is the principal element for causing autologous vein internal arteriovenous fistula to fail, and autologous vein internal arteriovenous fistula blood flow is lower,
The probability that thrombus occurs is bigger, this point can be verified by Color doppler ultrasound technology.Clinically, medical staff
To the assessment combination color Doppler ultrasonography of internal arteriovenous fistula, patient education and intervening measure are given.But due to medical care people
Member grasps the different of knowledge, and the accurate introduction on discharge of homogeneity can not be provided for patient, and patient is right by the inspection of outpatient service medical technologies
Medical blood purification specialist or nurse cause consultation time long afterwards.
The prior art is found the problem in the case where not puncturing, however is that encounter problems in puncture can also be timely
Judgement and analysis, handle it is even more important.
When detection, instrument probe needs hand-held, cannot well by instrument probe and the perpendicular shape of skin surface, and
The bad assurance of plumbness easily causes becoming larger for measurement error, while shortage vertically moves instrument probe and stablizes vertically in skin
Structure on surface, strength size, which not easily passs through intuitive pressure data and observe, when firmly operation presses instrument probe is suitable for
Firmly, firmly smaller to be pressurized to superficial vein, and be unfavorable for detecting, the generally hand-held needle head structure injected of medical staff and
The angle of injection is maintained between 45 ° to 60 °, and it is not specific definite enough to inject angle, while being lacked associated adjustment and being injected angle
Supplementary structure.Therefore, a kind of intelligent internal arteriovenous fistula functional analysis instrument is proposed regarding to the issue above.
Some patientss occur that blood flow is bad, artery forces down after piercing or vein pressure increases and (excludes other feelings such as hemotoncus
Condition) phenomena such as, in order to be better understood by the actual flow of blood amount of the patient's internal arteriovenous fistula, thickness of arteriovenous tube wall, thrombus, narrow
Specific location, in the case where retaining puncture needle, multi-functional analyzer can pass through detecting head and connect internal arteriovenous fistula
Needle, such as detects thrombus at the case where analyzing actual flow of blood amount, the endangium of site of puncture etc., can be driven in time intravenous
Extract or do local thromboembolism treatment in fistula out, narrow for vein end can also carry out detection analysis.Reduce puncture pair repeatedly
In the damage of blood vessel.
