Specific embodiment
Embodiment 1
A kind of compression cord of one-hand operation, as shown in Figs 1-4, including elastic band 1, compression hemostasis device, coarse adjustment
Device 4 and micromatic setting 5.
Elastic band 1 is two elastoplasts, is equipped with compression hemostasis device at the position that elastic band 1 is in contact with blood outlet.
Any one in air bag in the prior art, gauze 3 or spiral compression apparatus can be used in compression hemostasis device.Hemostasis by compression
Pressure sensor is equipped at device compression, pressure sensor output end is connected with the input terminal of control unit, control unit it is defeated
Outlet is connected with the input terminal of display screen.Pressure sensor pressure value collected, can be with maximum set in control unit
Pressure value is compared, and when maximum pressure value of the detected pressure value beyond setting, is shown on a display screen, with
Warning patient is cautiously adjusted.Pressure sensor pressure value collected, can with the historical pressures value that is stored in control unit into
Row compares, and refers to when adjusting 1 elasticity of elastic band for patient.Control unit uses singlechip chip in the prior art.
Rack and rinion adjustment 4 is for tentatively adjusting the elasticity of elastic band 1, using the nylon evil spirit on clothes, shoes, gloves
Art patch 2,2 one side of nylon velcro are the seta of harder buckle, and another side is the fiber of small, flexible.By 2 band of nylon velcro
Seta is placed on one side on the inner plane that an elastic band 1 is in contact with skin, by being placed on one side with fiber of nylon velcro 2
On another elastic band 1 and the discontiguous outerplanar of skin, the area that the two sides by controlling nylon velcro 2 is interlockingly connected can
Realize the coarse adjustment to 1 elasticity of elastic band.
Nylon velcro 2 is placed in the both ends of two elastic bands 1, separate nylon velcro 2 on two 1 length directions of elastic band
One end be connected respectively with micromatic setting 4.Micromatic setting 4 includes being fixed on the intracorporal retaining spring 5 of 4 shell of micromatic setting, electronic
Telescopic rod 6 and gear adjusting device, retaining spring 5, electric telescopic rod 6 are located along the same line and are oppositely arranged.A piece elastic force
With positioning plate 17 is all fixed at left and right sides of 1 one end, positioning plate 17 is fixedly linked with 5 free extension end of retaining spring, positioning
The flexible of spring 5 can drive elastic band 1 mobile by positioning plate 17.One end of another elastic band 1 is placed in 6 institute of electric telescopic rod
On fixed 4 shell of micromatic setting.
When gear adjusting device does not position retaining spring 5, electric telescopic rod 6 can be such that retaining spring 5 is compressed to
Most loose position when the initial bit of fine tuning, i.e. elastic band 1 are finely tuned.
The present embodiment middle gear regulating device is the screw 7 being threadedly coupled with 4 shell of micromatic setting, if there are five screw 7,
Screw 7 penetrates in micromatic setting 4 and extends along perpendicular to 5 direction of motion of retaining spring, is screwed into micromatic setting 4 by screw 7
Depth to control the shift position of retaining spring 5.When screw 7 is screwed into the depth in micromatic setting 4 extremely than 17 top surface of positioning plate
When the distance of upper plane is big in 4 shell of micromatic setting, screw 7 can position positioning plate 17;Conversely, positioning plate 17 moves position
It sets.
When using the present embodiment, adjusting screw 7 be screwed into the depth in micromatic setting 4 with control the movement of retaining spring 5 or
Positioning.When most loose position when needing makes elastic band 1 be restored to fine tuning, i.e., 5 return of retaining spring need to can be pressed electric expansion
Retaining spring 5 is recoiled to the initial bit of fine tuning by bar 6.
