Description
Technical field
Originally practical newly to belong to the field of medical instrument technology, it is related to a kind of portable type drive blood hemostasis ring, and in particular to Yi Zhongyong
Patient comfort and the drive blood hemostasis ring convenient to use carried are improved compared with similar product in surgery limb operation.
Background technique
The blood supply of the limbs of people is to reach limbs by heart and arteries blood transfusion, and backflow by vein blood vessel
Heart is returned, blood circulation is completed.When performing surgical operation to limbs, blood vessel may be destroyed, is caused bleeding, therefore in order to anti-
One bloodless surgical environments of loss and creation of Hemostatic Oral Liquid, need to carry out drive blood since acral, blood are allowed to flow back to
Heart, while temporarily being stopped blooding in the surgery location of limbs close to heart side, blood transfusion of the heart to limbs is truncated, completes operation
Afterwards, it needs to restore the blood supply to limbs.And realize this function, need certain medical instrument and method to realize.
It is traditional to drive blood mode, then to use esmarch bandage or bandage certainly for limb elevation 2-3 minutes before limb operation
Acral beginning makees spiral wrap to proximal part, until at binding tourniquet, so as to the intracorporal blood of the limb is driven to only
It is more than blood band plane.But complicated operation for this kind of mode, and operator is needed to have certain experiences, to ensure in the winding hour circle
There are gaps between circle, drive blood effect to ensure, and because the operating time is long, and need integrally to carry out a level pressure to suffering limb
The winding of power, patient perceptions are often more painful.
Patent CN1301085C discloses a kind of device that blood is excluded from limbs, is by elastic shrinkage ring and elasticity
Lacing jacket is constituted, and the elasticity lacing jacket can be on the elastic shrinkage ring, wherein the elastic ring and at least partly rolling up
The elastic lacing jacket being wound on the elastic ring constitutes the elastic shrinkage annulus equipment with an internal diameter, is used for described
Apply pressure on limbs, wherein when the elastic bunch is tightly placed in and gradually spreads out on the limbs, the elastic shrinkage annulus
Internal diameter increases, and wherein the internal diameter is always sufficiently small to keep the pressure to be higher than the arterial pressure of the limbs.This is specially
Technology contents provided by benefit although solve in above-mentioned traditional approach implement the time it is long, but needed in operating process " survey choosing, set
Draw, cut, cut " FOUR EASY STEPS, it is still desirable to operator has certain operating experience, and still using elastic lacing jacket substitution
The mode of Esmarch's bandage winding carries out drive blood, needs to remove the elasticity lacing jacket covered on limbs when carrying out limb operation, and
The device is not still suitable for sufferer one man operation from the point of view of use process, and it is real to generally require 1-2 medical staff's auxiliary operations
It applies.
