Description

Agraffe type tourniquet

This utility model relates to a kind of medical buckle type tourniquet, belongs to medical equipment, specifically is meant tourniquet.

Present widely used tourniquet mainly is the hose tourniquet, the method of during use a hose being tied up knot with maneuver is tied up knot on the limbs of need puncture, the major defect that exists is: need tie a knot during use, it is not too convenient to operate, time is long, sometimes hose also can skid, come off when hose (especially use new), and tightness is difficult to be grasped and regulate; When loosening, easily cause needle point to skid off blood vessel.

The purpose of this utility model is: overcome above-mentioned the deficiencies in the prior art part, provide a kind of operation not only easy but also fast, the scalable tightness is tied up the firm buckle type tourniquet of knot.

The purpose of this utility model is achieved like this: the end at the elastic webbing of hose or rubber belt and so on connects a hasp, connects one at the other end of elastic webbing and takes loop.During use, only need to elongate elastic webbing, and be wrapped on the limbs, with hasp with take loop and fuse and to reach the hemostatic purpose.When loosening, mention an end of taking loop, take loop and just break away from hasp, whole tourniquet is just untied automatically.Hasp with take being connected of loop and elastic webbing, fixed mode can be varied, can adopt clamping, ties up, method such as bonding, riveted joint.

Below in conjunction with accompanying drawing, most preferred embodiment of the present utility model is elaborated respectively.

Embodiment 1:

Exemplified a kind of embodiment that adopts hose 4 to make elastic webbing among Fig. 1,2.Among the figure, what an end of hose 4 connected a block length bar shaped takes loop 5, and taking has button hole in a row 6 on the loop 5, and button hole 6 is circular, also can be square, rectangle etc.The other end at hose 4 connects a hasp 1, and hasp 1 is provided with protruding button 2, and protruding button 2 slightly is little column, and the end is slick and sly slightly to tilt to the elastic webbing direction, and it is hook-shaped that the end also can be, and hook is towards the direction of hose, so that protruding button 2 is difficult for skidding off after buckling in the button hole 6.The shape of protruding button 2 can be decided according to button hole 6 selected shapes.Be respectively equipped with fixedly loop 3 on an end of taking loop 5 and hasp 1, insert respectively in the fixedly loop 3 of taking loop 5 and hasp 1 at the two ends of hose 4, and the three is fused.For the slippage in fixing loop 3 of the two ends that prevent hose 4, in hose 4 two ends leather hoses, fill in a little block length respectively and be slightly larger than the fixedly stator 7 of loop 3, to support the big mouth of pipe, prevent slippage.

Exemplified another kind of elastic webbing projection rubber belt 8 among Fig. 3.The two ends of this band are provided with the fixedly projection 9 of usefulness.Cited hose 4 among projection rubber belt 8 alternative Fig. 1,2 need not stator 7 during installation, projection 9 has worked to stop rubber belt slippage on fixing loop 3, thereby has simplified manufacturing process.

Embodiment 2:

This also is a kind of embodiment that makes elastic webbing with rubber belt for Fig. 4, mainly represented this elastic webbing and hasp among the figure and taken connected mode between the loop: hasp 1 is a T font joint with taking the end that loop 5 links to each other with rubber belt, the two ends of square hole rubber belt 10 have square hole 12, during connection, only need hasp 1 and the T font joint 11 of taking loop 5 are inserted in the two ends square hole 12 of square hole rubber 10, just they can be fused.

Embodiment 3:

See Fig. 5, hasp 1 is provided with buckle 13 among the figure, and buckle 13 is the jaw shape, and oral area is less, and the bottom is bigger, and there are several tooth 16 symmetrical row's examples on the both sides of taking long limit, loop 5 upper edges, (tooth 16 also can all only be arranged example on one side).Endless-belt 15 passes hasp 1 and takes connecting ring 14 on the loop 5 with hasp 1 with take loop 5 and fuse.Endless-belt 15 also can select for use other elastic webbings to substitute.The width of between cog 17 is slightly larger than the thickness of buckle 13, and the width of taking loop 5 is slightly greater than the width of buckle 13 oral areas.During use, be wrapped in tourniquet on the limbs after, choose degree of tightness, the between cog 17 of taking loop 5 is pressed in the buckle 13, taking loop 5 will be locked, tourniquet is just brought into play its effectiveness.

Embodiment 4,5:

Fig. 6 and Fig. 7 have exemplified the embodiment of two kinds of adjustable hasps respectively.This hasp is by regulating the length of hasp, reaches to change tourniquet hasp and the distance of taking between the loop, to adapt to the too tiny person's use of child or limbs.Hasp is formed by connecting by cramp 18 and contact pin 21 two parts, and the two is detachable, Fig. 6, the 7th, the state diagram when the two is taken apart.Shown in Figure 6 is the adjustable hasp of a kind of button, and adjusting button 20 is arranged in contact pin 21, and fixedly loop 3.Adjusting button 20 is the circle mill and eats head, and top is round end, and the bottom is a small cylinder, and the radius of round end is bigger.On cramp 18, there is protruding button 2 and to tease and ridicule knothole 19, adjustment hole 19 is made up of the circular hole and the oblong aperture of intercommunication, circle hole radius is slightly larger than the round end radius of adjusting button 20, the width of slotted hole is slightly greater than the radius of adjusting button 20 bottom small cylinders, less than the round end radius, be fixed on the oblong aperture position after making adjusting button 20 buckle into adjustment hole 19.During use, adjusting button in the contact pin 21 20 is moved to the circular hole position of adjustment hole 19, contact pin 21 is separated with cramp 18, again adjusting button 20 is pressed in the circular hole of selected adjustment hole 19 again according to Len req then, and draw to the oblong aperture direction, so locking again, cramp 18 and contact pin 21 is integrated.The adjustable hasp of a kind of hook-type shown in Figure 7 is to adopt the mode of hook that cramp 18 and contact pin 21 are fused, and is provided with hook 22 in contact pin 21, is provided with several parallel engage a gears 23 on cramp 18.During use,, select suitable engage a gear 23, will link up with 22 and hang on the engage a gear 23,, in the time of need readjusting, can take off hook 22 and reselect so cramp 18 just links together with contact pin 21 according to Len req.

Embodiment 6:

Referring to Fig. 8, shorter at 25, one of the male and female loops of the bonding block length bar shaped of the two ends of elastic gum belt 24 difference, one longer, and the direction of being glued that the hook of two male and female loops 25 is perverse 26 is opposite.During use,, two male and female loops are overlapped in position according to Len req.

Hasp 1 and take loop 5 and can use injection molding.During this utility model operation, the elongation elastic webbing is wrapped in it simultaneously to be needed on the hemostatic limbs position, hasp 1 infra, take loop 5 last, the degree of degree of tightness is selected suitable button hole 6 as required, or tooth 17 presses and takes loop 5, treats that vein can be made Venipuncture by temporary blocking-up after full.After puncture finishes, only need mention an end of the disconnected elastic webbing of taking loop 5, tourniquet is just loosened automatically.

The utlity model has following advantage:

1, easy to use, reliable, easily regulate, elastic webbing can slippage; 2, the time economize, the efficient height; 3, loosen and can not affect limbs in the tourniquet, can prevent that needle point is from the blood vessel slippage.

Temporary blocking-up venous return when this utility model not only can be used for various venous transfusions, transfusion, injectable drug or venous blood collection, but also can be used for the hemorrhage interim hemostasis of limb trauma, the temporary artery occlusion of some operations of extremity; And be used to check varicose veins of the lower extremity test.
