Description
Technical field
The invention relates to a kind of Hemostasis, particularly relate to a kind of smaller haemostatic pressure of utilization, same through multiple spot
When method of the pressure to stop blooding.
Background technology
On clinical medicine, after puncture or the blood vessel of wound needs effectively stopped blooding, such as puncture or wound it is coronal
Fistula hemostasis after the postoperative radial artery hemostatic of arterioplasty or hemodialysis etc..By taking hemodialysis as an example, platform
The patients with chronic renal failure number in gulf rises year by year, and renal failure, can not be by the generation of human body mainly because kidney loses function
It thanks to waste to excrete and accumulated in vivo through kidney, therefore sufferer needs periodically receive hemodialysis, Fang Nengwei
Hold healthy living and life.So-called hemodialysis is mainly the kidney for replacing sufferer to lose function, is spread with concentration
(diffusion) and convection current (convection) principle removes moisture extra in sufferer blood, toxin and waste.
Before hemodialysis, sufferer must first receive arteriovenous fistula art, connect between an artery and a vein for arm
A fistula is connect, when washing kidney every time, nursing staff can stamp puncture needle on fistula, the blood drainage of sufferer be come out, by blood
Liquid dialysis machine, then washed blood is made to flow back in patient, so by constantly recycling, takes around 4-5 hours, just complete
Haemodialysis.After the completion of hemodialysis, nursing staff must remove puncture needle, since puncture needle is quite thick, because
This needs to cover point of puncture at once with cotton after pulling out puncture needle and profit presses with finger, and pressure and pressing time are usually dependent on doctor
The experience of shield personnel continues to stop point of puncture pressure using the finger of tourniquet substitution pressing immediately after blood by after stabilized
Blood.
The traditional tourniquet clinically used is elastomer as bandage made of material, meeting when being stopped blooding
Because the pressure tightened of winding can not be quantified, apply that pressure is excessive or the situations such as insufficient pressure so that being easy to happen, when tourniquet institute
The pressure of application can cause the narrow contracting of fistula and embolism when excessive, finally result in function forfeiture, and can make end microcirculation blood supply
Deficiency causes histanoxia.In addition, when tourniquet pressure applied is insufficient, it will cause washing kidney fistula wound not stopping blooding,
And generate the danger of loss of blood.
Therefore inventor proposes the improvement design about tourniquet then, as 98 years Augusts of TaiWan, China are announced on the 11st
Novel No. M362680 " tourniquet device " Patent Case is an example, and it includes a bandages, and is individually fixed in a biography on bandage
Sensor and an attention device, the bandage are fixed on the hemostasis convex block on band body including a band body and one, and sensor is disposed on
On bandage and can sense bleeding blood vessel blood flow smooth degree and export a sensing signal, attention device be and sensor signal connect
It connects, and the sensing signal can be corresponded to and generate a message for indicating the vascular flow smooth degree, through the sensing being fixed on bandage
Device can correspond to blood flow smooth degree output sensing signal, and attention device can correspond to the message that output represents blood flow smooth degree automatically, convenient
The case where message that the person that washes kidney is directly exported by attention device learns current fistula, and also need not be with when urging fistula and being stopped blooding
When wear a stethoscope listen survey fistula blood flow sound.Only, which lacks setting for automatic feedback adjustment pressure mechanism
Meter causes still to be easy to happen tourniquet in use and integrally presses excessive, causes end microcirculation blood supply insufficiency and cause to occur
Histanoxia situation, so in using upper and ideal not to the utmost.
Invention I 533835 that for another example TaiWan, China is announced on May 21st, 105 " intelligent suitable pressure tourniquet with only
Blood method " Patent Case, disclosed intelligent suitable pressure tourniquet are set to the control of the band outer surface equipped with a band, one
Device, one are set to pneumatophore inside the band and one are set to the pressure plare of the band medial surface.The controller is internally provided with
One presser unit, a relief valve, a pressure sensing cells and an IC control chip, the presser unit, relief valve and pressure-sensing
Unit is respectively communicated to the pneumatophore, and IC control chips are then respectively and electrically connected to the presser unit, relief valve and pressure
Sensing unit.The mean arterial pressure that an area to be stopped blooding is measured by the sensing unit recycles IC controls chip, presser unit
It interacts in pneumatophore with relief valve, so that pressure plare is had a haemostatic pressure and act on the area to be stopped blooding.However because of the intelligence
The suitable pressure tourniquet of energy type and Hemostasis treat hemostasis area (puncturing blood outlet hole) pressure merely with the pressure plare and stop blooding, blood stream
The fall of speed is slower, for the weaker sufferer of some coagulation functions, when stopping blooding with greater need for longer pressure
Between, although No. 533835 invention cases of the I can provide setting bleeding stopping period, the setting of this bleeding stopping period can only be dependent on medical care people
The experience of member if only being set with experience, can inevitably be sent out if medical staff does not notice whether the coagulation function of sufferer is weaker
Raw bleeding stopping period has arrived, and the situation that do not stop blooding completely yet is had been found that after separating the intelligent suitable pressure tourniquet；Conversely, for
Due to drug administration for the stronger patient of coagulation function, bleeding stopping period setting is too long for some, then can be easy to happen fistula mistake
The problems such as effect.
Therefore, an effective hemostatic fashion how is developed, avoids using excessive improperly haemostatic pressure, sufferer is reduced and exists
Sense of discomfort during hemostasis obviously has its necessity.In addition, the haemostatic pressure for being less than vessel retraction pressure using one, it can be in post-hemorrhagic period
Between avoid excessively oppressing fistula, and then effectively extend the service life of fistula.

As shown in Figure 10, in the experimental situation of simulation, the fluid circuit soft to one bestows single point pressure, two point pressures
It with multiple spot (4 points) pressure, is as a result shown under identical pressure, two point pressures and four point pressures are than single point pressure for drop
Low flow velocity has more significant effect.By taking pressure 120mmHg as an example, single-point pressure makes flow velocity have dropped 19.7%, and 2 points of pressures make
Flow velocity has dropped 50.4%, and 4 points of pressures make flow velocity have dropped 81.6%.And the method for the embodiment of the present invention, it can pass through at 2 points
Or (4 points) pressures of multiple spot, that is, utilize main hemostasis part 2 compressing to stop blooding in point of puncture A1 and the auxiliary of at least more than one
Part 3 is oppressed in point of puncture A1 neighbouring positions.The application pressure that traditional single-point pressure can be improved needs to reach 200mmHg mostly
More than, it just can ensure that generation haemostatic effect, but the ischemic injury of injury of blood vessel or rear end tissue can be caused because excessively pressurizeing.
In addition, usually when decline flow velocity reach 60% when, but blood still can smooth flow pass through, it is possible to as the flow velocity effectively to stop blooding
Reduction amount, but can be because of sufferer constitution and wound situation difference, in addition, when declining flow velocity and reaching 60%, hence it is evident that can
Know the pressure value needed for 2 points of pressures close to 140mmHg, and the pressure value needed for (4 points) pressures of multiple spot then only proximate to
100mmHg, it follows that for 2 points or the hemostatic fashions of (4 points) of multiple spot pressure, without bestowing excessive pressure
(200mmHg or more) can reach good Pressur hemostatic effect.
The Hemostasis of the embodiment of the present invention, it is applied widely, such as to be applicable to coronary angioplasty postoperative
Radial artery hemostatic washes the Pressur hemostatic of the hemostasis of arteriovenous fistula and limbs arterio-venous catheter when pulling out after nephrosis people washes kidney
Deng.Its is easy to operate, and ease of use is good, and during Pressur hemostatic and energy effective protection fistula is not excessively pressed, and is subtracted
Few impact and initiation fistula complication for fistula, and fistula reconstruction rate can be reduced and ensure patient vitals' safety.In addition, this
The revealed hemostasis device of inventive embodiments, has the function of pressure measurement, thus can the pressure applied amount of feedback in real time, and by only
Blood device itself or the display of other portable electronic devices (such as smart mobile phone), thereby sufferer can be according to clinical staff institute
The pressure value of setting oneself wears the hemostasis device, and hemostasis is learned through the display screen on the hemostasis device is watched
As a result, the hemostasis device can also provide the physiological parameter by being measured on blood vessel simultaneously simultaneously, such as Hemodynamic environment, blood vessel pulsation or blood oxygen
Value, current body and vascular health situation are learnt for sufferer.
As depicted in figs. 3 and 5, in addition, the controller 6 of the hemostasis device can also have one to be electrically connected the control chip
61 timing unit (not shown) thereby provides hemostasis clocking capability, when bleeding stopping period timing expires, the control chip 61
