Description
Technical field
The utility model relates to the field of medical instrument technology more particularly to a kind of internal arteriovenous fistula fixators.
Background technique
Chronic hemodialysis patient is increasing, and internal arteriovenous fistula is hemodialysis patient " lifeline ", due to internal fistula
Do not allow easy infection, can provide than faster Hemodynamic environment, therefore is the most common vascular access of hemodialysis patients.How correctly to make
With internal arteriovenous fistula, extends internal fistula service life and guarantee going on smoothly for haemodialysis, it is most important for hemodialysis patients.
Chronic hemodialysis patient generally requires and carries out 3 dialysis per thoughtful hospital, and 4 hours every time.It is needed when dialysis every time
Internal arteriovenous fistula is used, dialysis nurse has an acupuncture treatment, punctures internal arteriovenous fistula, draws from arterial end the blood in patient body
Out, by dialyzer, after removing moisture and toxin extra in blood, blood is purified, then from the vein of internal arteriovenous fistula
End returns in patient body.This completes a haemodialysis.
Internal arteriovenous fistula multidigit is in the left side upper limb of patient, in blood dialysis, it is desirable that patient must keep left side
Upper limb not move, and left side upper limb cannot be bent and raise, to guarantee going on smoothly for haemodialysis.However in clinical position
In, it has been found that during dialysing 4 hours, the upper limb for maintaining internal fistula completely does not move to be highly difficult patient, is suffered from
Person needs to keep the completely awake arm that can just gain control of oneself not move.And in 4 hours dialysis procedures, patient often exists
Hypnagogic state, the movement that patient is easy to appear upper limb is even bent, therefore the Hemodynamic environment for being easy to appear dialysis is inadequate, puncture needle position
Movement is set, or even is fallen off, the problem for causing blood loss, shock etc. serious.Clinically there are some malnutritions simultaneously, the state of mind is not
Good patient, it is also difficult to allow patient to accomplish that the upper limb for maintaining internal arteriovenous fistula does not move, thus there is hidden danger medically.
Hemodialysis patients are also at anxiety and nervous state thus, if dialysis is unsuccessful or loses blood seriously, can bring pain to patient
And loss, while also medical personnel being allowed to perplex very much.Currently, clinically dialysis patient internal arteriovenous fistula is in use all
It does not fix, patient's arm is directly placed on bed or on chair.
Therefore, the existing technology needs to be improved and developed.
Utility model content
In view of above-mentioned deficiencies of the prior art, the purpose of this utility model is to provide a kind of internal arteriovenous fistula fixator,
It aims to solve the problem that chronic hemodialysis patient upper limb in carrying out blood dialysis and cannot remain motionless, stretch and be unfolded
Problem.
The technical solution of the utility model is as follows:
A kind of internal arteriovenous fistula fixator, wherein the internal arteriovenous fistula fixator includes:
Pedestal, described base upper surface one end are provided with a support protrusion, and the support protrusion is connected with an arm support,
The arm upper surface of support is provided with an arc groove；
Front end, the rear end of the arm upper surface of support are separately provided for the preceding fixed ring of fixed arm, fix afterwards
Ring；
The pan frontward end is vertically installed with one for adjusting the adjusting knob of angle between arm support and horizontal plane.
Preferably, the internal arteriovenous fistula fixator, wherein the support protrusion is connected by pin shaft and arm support
It connects.
Compared with prior art, internal arteriovenous fistula fixator provided by the utility model, comprising: pedestal, the pedestal
Upper surface one end is provided with a support protrusion, and the support protrusion is connected with an arm support, and the arm upper surface of support is set
It is equipped with an arc groove；Front end, the rear end of the arm upper surface of support be separately provided for fixed arm preceding fixed ring, after
Fixed ring；The pan frontward end is vertically installed with one for adjusting the adjusting knob of angle between arm support and horizontal plane, energy
It is enough that effectively patient's upper limb is fixed on arm support, the influence of patient's oneself factor is avoided, allows the patient to access very
Good rest, meanwhile, be conducive to ensure the safety of medical treatment and going on smoothly for clinical treatment.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the internal arteriovenous fistula fixator preferred embodiment in the utility model.
Fig. 2 is the cross-sectional view of the internal arteriovenous fistula fixator preferred embodiment in the utility model.
Specific embodiment
The utility model provides a kind of internal arteriovenous fistula fixator, to make the purpose of this utility model, technical solution and effect
Fruit is clearer, clear, referring to the drawings and gives an actual example to the utility model further description.It should be appreciated that herein
Described specific embodiment is only used to explain the utility model, is not used to limit the utility model.
As depicted in figs. 1 and 2, in a kind of internal arteriovenous fistula fixator that the utility model preferred embodiment provides, comprising:
Pedestal 100, described 100 upper surface one end of pedestal are provided with a support protrusion 101, and the support protrusion 101 is connected with an arm
Support 200,200 upper surface of arm support are provided with an arc groove 201；The front end of 200 upper surface of arm support, after
End is separately provided for preceding fixed ring 300, the rear fixed ring 400 of fixed arm；100 front end of pedestal is vertically installed with one
For adjusting the adjusting knob 500 of angle between arm support 200 and horizontal plane.
Internal arteriovenous fistula fixator provided by the utility model is a kind of for being auxiliarily fixed one of upper limb on the left of patient
Kind device.The Design of length of the internal arteriovenous fistula fixator is at the size of men and women's property, and suitable male and female patient's is upper respectively
Limb length.Upper limb (including left side forearm and left hand) can be comfortably placed on the fixator by the patient with internal arteriovenous fistula
On, remaining the state stretched and be unfolded, dialysis nurse can clearly observe the position of needle, meanwhile, in fixator
The arm that middle section and front end have 2 annulus to block patient, avoids its movement, advantageously ensures that the safety of medical treatment.Such patient
During dialysing 4 hours, also available better rest improves the comfort level and safety of patient, also more humanized.
In the further preferred embodiment of the utility model, the support protrusion 101 passes through pin shaft 600 and arm support 200
Connection.The pin shaft 600 can make arm support 200 be rotated around the pin shaft 600, can item by adjusting knob 500
Part upper limb placed angle, so that being adjusted to the angle of patient's the most comfortable.
In conclusion internal arteriovenous fistula fixator provided by the utility model, comprising: pedestal, the base upper surface
One end is provided with a support protrusion, and the support protrusion is connected with an arm support, and the arm upper surface of support is provided with one
Arc groove；Front end, the rear end of the arm upper surface of support are separately provided for the preceding fixed ring of fixed arm, fix afterwards
Ring；The pan frontward end is vertically installed with one for adjusting the adjusting knob of angle between arm support and horizontal plane, Neng Gouyou
Patient's upper limb is fixed on arm support by effect, avoids the influence of patient's oneself factor, allows the patient to access well
Rest, meanwhile, be conducive to ensure the safety of medical treatment and going on smoothly for clinical treatment.
