Detailed description of the invention
For the technological means making the present invention realize, creation characteristic, reach purpose and be easy to understand with effect, below in conjunction with
Detailed description of the invention, is expanded on further the present invention.
Such as Fig. 1, shown in 4, a kind of hemodialysis upper limb fixing device, including two for being separately mounted to upper and lower arm
1, the linking arm 8 that the fixed cover 4 on 3 and two ends are connected with two fixed covers 4 respectively, described fixed cover 4 is by two and half body buttons
Connecing and form, concrete, two and half body one end are hinged, and the other end is connected by snap close, and the inwall at fixed cover 4 is provided with can be with
The cushion 5 that upper and lower arm 1,3 shape adapts, cushion 5 both can push down the conduit being connected with venipuncture needle, so that quiet
Arteries and veins puncture needle will not tamper easily, and patient can be made again to feel comfortably cool.Linking arm 8 becomes different shapes, then suffer from during hemodialysis
Person's upper limb will be fixed to different postures.When linking arm 8 is in line type, patient's upper limb becomes straight configuration；When linking arm 8
Time angled, the case of bending that patient's upper limb is the most angled.
As shown in Figure 1, 2, 3, owing to the hemodialysis time is long, patient is fixed to a posture upper extremity length time can make trouble
Person feels under the weather, and needs to regulate neatly patient's upper limb for this by anchor, to reduce patient in blood dialysis
Sense of discomfort.Now, linking arm 8 includes that first and second linking arm 81,82, described first linking arm 81 include and a fixed cover 4
The the first arm body 811 connected and the second arm body 812 being slidably located on described first arm body 811, on described second arm body 812
Being provided with hinge 8121, an end face of described hinge 8121 has been evenly distributed multiple first hole 8122, location, and preferably first is fixed
The quantity in hole 8122, position is six, and described second linking arm 82 includes the 3rd arm body 821 being connected with another fixed cover 4 and slides
Moving and be set in the 4th arm body 822 on described 3rd arm body 821, described 4th arm body 822 is provided with for installing hinge 8121
Hinge axis hole 8221, be provided with rotatable insertion in described first hole 8122, location with to the in the end of described hinge axis hole 8221
One, two linking arms 81,82 carry out the first lock screw 9 of hinged locking；Between first and second arm body 811,812 and third and fourth arm
All pass through the second lock screw 10 between body 821,822 and carry out slide lock.When needs regulation upper limb posture, unclamp the first lock
Determine screw 9 and the second lock screw 10, make patient oneself that upper limb to be adjusted to a comfortable posture lentamente, now first,
Length and the angle of two linking arms 81,82 can change adaptively, tighten the first lock screw 9 and the second locking the most again
Screw 10, makes patient's upper limb be fixed with the posture after adjusting.
As the further improvement of such scheme, as shown in Figure 4, near the one of elbow portion 2 on described fixed cover 4 outer wall
End has cannelure 41, circumferentially has the second hole, location 42, described first and third arm body 811,821 in described cannelure 41
It is connected with fixed cover 4 by described cannelure 41 split ring 6 that is interior and that rotate can be enclosed within around fixed cover 4 axis, described split ring
6 are attached locking, first and third arm body by rotatable the 3rd lock screw 7 inserting the second hole 42, location with fixed cover 4
811,821 fixing with split ring 6 are connected, in split ring 6 can be enclosed within cannelure 41 easily or taking-up in cannelure 41, and second
Hole 42, location can arrange multiple, thus can forward linking arm 8 to different position according to patient demand, inside elbow portion 2
Or outside, and then patient is facilitated to use.
As the further improvement of such scheme, as shown in Figure 4, fixed cover 4 with cushion 5 have the connected
One, two steam vent 43,51.Although cushion 5 can increase comfort level when patient's upper limb is fixed, but the time one is long, patient
Upper and lower arm 1,3 can be generated heat because of airtight by bearing, uncomfortable, therefore arranging above-mentioned first and second steam vent 43,51 can
To solve this problem.
The ultimate principle of the present invention and principal character and advantages of the present invention are more than shown and described, for this area skill
For art personnel, it is clear that the invention is not restricted to the details of above-mentioned one exemplary embodiment, and without departing substantially from the present invention spirit or
