Description
Technical field
This utility model relates to medical instruments field, particularly a kind of tourniquet for hemodialysis procedure.
Background technology
In blood dialysis, have and need to adopt central venous cattaeter or Direct perforantes tremulous pulse and vein, need to carry out hemostasis by compression in the later stage, such as existing conventional arteria radialis compressing tourniquet, for fixing band two ends are provided with thread gluing, centre is provided with a pressing plate, is provided with an air bag below pressing plate.After air bag being pressed in site of puncture during use, with special inflation syringe to airbag aeration, the balloon tamponade after inflation is on site of puncture thus realize radial artery hemostatic.Also after needing special inflation syringe to be connected with air bag during venting, air is extracted out.Problems existing is:
The area of air bag and contact skin is larger, will the hemostasis by compression effectively in site of puncture, the air in air bag is needed to have larger pressure, when pressure enough after, fixing band also bears same pressure with other local skin contacted, fixing band is a plastic tape, its edge forms shearing force to skin, in multiple hours of hemostasis, under fixing band causes skin, blood flow is not smooth, cause patient numb, livid purple, thrombosis makes the further swelling of skin, severe one even causes nerve injury, arterial occlusion, a lot of patient can not tolerate because of pain, this phenomenon is particularly general in more fat patient.Pressing time is not enough or pressure not then easily oozing of blood, hemorrhage, even form ecchymosis.
Medical personnel be expert at hemostasis by compression time, need operated by two people, people's colligation fixing band, another people is with special inflation syringe to airbag aeration, and work efficiency is lower.Dermathemia swelling more needs the air pressure in adjustment air bag repeatedly, fills, bleed air operation is loaded down with trivial details.
Because balloon sites and contacting blood, so can only single use, waste be comparatively large, also not environmentally.
Chinese patent literature CN101843513A discloses a kind of compression cord, fixing band is provided with a pressing plate, and other positions on fixing band except pressing plate are provided with multiple air bag, and air bag was connected with compressing gasbag by communicating pipe; Described pressing plate one end is provided with supporting bracket, is provided with a compressing head near the position of the other end.Overcoming above defect to a certain extent, but still there is the problem of complicated operation, using in the compressing gasbag process of inflating, needing pressing plate reliably to fix, avoid producing displacement, medical personnel carry out operating and still there is certain difficulty.And in pressing plate, oppress structure protruding centered by the structure of head, compression molding is comparatively difficult.

Detailed description of the invention
As in Fig. 1 ~ 3, a kind of tourniquet, comprise belt body 1, be provided with pressing plate 2 in belt body 1, elasticity location-plate 22 and the oppression department 23 of pressing plate 2 pass from the inwall of belt body 1, in preferred scheme, the structure of described pressing plate 2 is, one end, beam portion 21 of pressing plate 2 is provided with elasticity location-plate 22, is provided with oppression department 23 near the position of the other end, oppression department 23 needs the position of hemostasis for being pressed in, oppression department 23 is for forming bulge-structure after bending.The structure of its Elastic location-plate 22, is convenient to whole pressing plate is located, avoids pressing plate displacement.And the structure of oppression department 23, then make the easy processed molding of oppression department 23.
Preferred scheme is as in Fig. 1 further, and described elasticity location-plate 22 free end cover has silica gel sheath 4.Structure thus, avoids the edge of elasticity location-plate 22 to be formed skin and shears, improve the effect preventing displacement simultaneously further.
The termination of belt body 1 is provided with the structure that connects, and preferred scheme is as in Fig. 1, and the described structure that connects is thread gluing, buckle or snap-fastener.The design of thread gluing is adopted in this example.
Be provided with multiple air bag 6 inside belt body 1, air bag 6 is connected with gas generating device 7 by least one breather 5.Preferably, varying in size of air bag 6, the air bag near pressing plate 2 is less, and the air bag away from pressing plate 2 is then comparatively large, thus after making airbag aeration, better oppresses pressing plate 2 in the position needing hemostasis.
Preferred scheme, as in Fig. 3, in described gas generating device 7, excitation cavity 73 is provided with exciter 71, and exciter 71 and electrode 74 are electrically connected, and be provided with medicine 75 of getting angry near electrode 74, excitation cavity 73 is connected with breather 5.Structure thus, excites by exciter 71 medicine 75 of getting angry, and produces a large amount of gas and pours air bag, and less than in the time of 1 second, air bag 6 can be full of, operation is very easy.Medicine 75 of getting angry in this example preferably adopts non-azide type gas generant composition in accordance, such as RDX type gas generant composition in accordance.Tolerance needed for this utility model is less, and the volume of medicine 75 of therefore getting angry is very little, therefore adopts Hydrazoic acid,sodium salt gas generant composition in accordance to be also feasible.Exciter 71 in this example adopts the pressing type exciter in similar lighter, utilizes instantaneous high pressure to excite to get angry medicine 75.
Preferred scheme is as in Fig. 1, and described breather 5 is many, and many breathers 5 are connected with excitation cavity 73 by air distributing device 76.Structure thus, makes air bag independent mutually, when single air bag leaks, does not also affect the use of whole device.
In preferred scheme, described breather 5 is provided with check valve 77.Structure thus, avoids gas leakage.
Further in preferred scheme, described breather 5 is connected for dismountable plug-in type with between air distributing device 76.Structure thus, can unload air distributing device 76 after inflation.
In preferred scheme, described air distributing device 76, excitation cavity 73 or breather 5 are provided with pressure limiting valve 78.Structure thus, when the blowing pressure exceedes limit value, namely unnecessary gas discharge from pressure limiting valve 78.Preferably pressure limiting valve 78 is arranged on air distributing device 76.
In preferred scheme, described exciter 71 be provided with avoid by mistake by protection ring.Structure thus, avoid exciter 71 by by mistake by, only take off protection ring, exciter 71 just can be pressed.
During use, with thread gluing 3, this utility model is fixed on the position needing hemostasis, the oppression department 23 of its center platen 2 faces the position needing hemostasis, and above being pressed in.Take off the protection ring of gas generating device 7, press exciter 71, exciter 71 excites medicine 75 of getting angry, thus produces a large amount of gas inject in air bag, and when the blowing pressure exceedes limit value, unnecessary gas is discharged from pressure limiting valve 78.After finishing using, take off and abandon pressing plate 2, remainder is reusable after sterilization, and gas generating device 7 cleans and can reuse after changing medicine 75 of getting angry.
The above embodiments are only optimal technical scheme of the present utility model, and should not be considered as restriction of the present utility model, and the embodiment in the application and the feature in embodiment, can combination in any mutually when not conflicting.The technical scheme that protection domain of the present utility model should be recorded with claim, the equivalents comprising technical characteristic in the technical scheme of claim record is protection domain.Namely the equivalent replacement within the scope of this improves, also within protection domain of the present utility model.
