Description
Technical field
This utility model relates to medical clamp technology field, relates in particular to a kind of internal arteriovenous fistula folder.
Background technology
Internal arteriovenous fistula is chronic renal failure (uremia's phase) dialysis patient " life line ", therefore, prolongs internal fistula and uses, and protects and keep the function of internal arteriovenous fistula, is the key that guarantees the uremic patient quality of life.Internal arteriovenous fistula is tremulous pulse to be linked to each other with vein and the specific blood vessels that forms, arterial blood flows directly into vein, its pressure is big, and blood flow is also big, and (1.4～1.6mm) puncture needle punctures need to use the comparison large diameter when carrying out hemodialysis, and need use anticoagulant in the dialysis, the patient is hemorrhage easily, so dialysis finishes to pull out and presses extremely importantly behind the pin, compressing time is generally 20～30min, the dynamics of pressing should be stopped blooding, and guarantees again can internal arteriovenous fistula be stopped up because pressing strength.
Now the mode of pressing that internal arteriovenous fistula is commonly used is: manually press and use elastic bandage to press.Manually press effectively controlled pressure, it is little to press strength, easily causes hemorrhage; It is big to press strength, easily causes stopping up; Compressing time length causes fatigue, particularly Nian Laotiruo patient; If oneself presses the patient, can only press a puncture orifice at every turn, the time of pressing 2 puncture orifice is longer; If need to reduce compressing time, need others to help and press.Elastic bandage is pressed the elastic bandage that is to use wide 3cm, is about 30cm, pinion arm with elastic bandage centered by point of puncture after pulling out pin, bleeding stopping period is 20～30min, the difficult control of this mode pressure, field of load is big, and stress point can not be confined to point of puncture; If stretch tight loosely, easily cause hemorrhage; Stretch tight tightlyer, easily cause stopping up; Long causing of the time of stretching tight stops up; Elastic bandage is less, hides in clothes, and some patient particularly forgetful and old patient can forget the time of unclamping, and causes the time of stretching tight long and cause obstruction; And the elastic bandage material is cloth and rubber band, and blood easily infilters in Bu Nei and the rubber band, and the time, long difficulty cleaned up.
The utility model content
The purpose of this utility model is to provide a kind of internal arteriovenous fistula folder at the deficiencies in the prior art, to solve hemostasis and the susceptible to plugging problem after internal arteriovenous fistula punctures, can safeguard internal arteriovenous fistula, prolongs the time that internal arteriovenous fistula uses.
To achieve these goals, this utility model provides a kind of internal arteriovenous fistula folder, comprise top arc, below arc, elastic component, one end of described top arc is pulling part, the other end of described top arc is provided with the pressure plare be used to the puncture orifice of pushing down internal fistula, one end of described below arc is articulated in the middle part of described top arc, the other end of described below arc is provided be used to that hold arm and supporting plate described pressure plare coupling, and described pressure plare is positioned at the top of supporting plate; Be provided with first junction between the hinged place of described top arc and the pressure plare, this first junction is near the hinged place of described top arc; Described below arc is provided with second junction, and this second junction is near a hinged end of described below arc; One end of described elastic component is connected in described first junction, and the other end of described elastic component is connected in described second junction, and described top arc and below arc can be opened or clamp.
Preferably, described elastic component is stainless steel spring.
Preferably, offer the position of shaking hands between second junction of described below arc and the supporting plate.
Preferably, described top arc, below arc are plastic plate.
This utility model beneficial effect is: 1) isostasy, stress point is fixed: the shape according to human arm designs, set suitable pressure according to the elasticity of elastic component and the size of arm, because supporting plate and pressure plare are stressed at same straight line, when being clipped on the arm, stress point is fixed, so haemostatic effect is good, be difficult for stopping up, can safeguard internal arteriovenous fistula, prolong the time that internal arteriovenous fistula uses; 2) reduce compressing time: generally pressing 10min can stop blooding, and maximum duration is no more than 20min; 3) human-saving: directly be clipped on the arm, do not need others to help and press; 3) size is fit to use, and exposes, and can not hidden by clothes, thereby the overlong time of avoiding pressing from both sides causes obstruction; 4) elastic component is stainless steel spring, and top arc, below arc are plastic plate, and be smooth with the contact surface of patient's arm, can not stab skin, in light weight, conveniently takes, and can use the chlorine-containing disinfection liquid soaking disinfection, recycling.
