Description
Technical field
The present invention relates to the research field of medicine equipment, more particularly, to a kind of mechanical infusion pressurizer and add
Pressure method.
Background technology
It is past when various public health emergencies such as field exploration, traffic accident, natural calamity, state of war etc. occur
It is past to produce more or less personnel's wound, and then cause the sick and wounded hypovolemic shock occur.During shock in human body effectively
A kind of syndrome shown when inadequate circulatory blood volume and the low perfusion state of tissue.It can occur in many kinds of diseases, especially
When being more common in severe trauma, and it is one of the most common complication of severe trauma and important cause of death.That suffers a shock is common
Feature is：Generation is more unexpected, quickly grows, and general severe trauma can cause to bleed profusely or a large amount of plasma extravasations are between tissue
Gap, cardiac output is substantially reduced, and microcirculatory perfusion amount declines, and histocyte draws microcirculatory perfusion amount obstacle and occurs dysbolism
Cause meronecrosis and vital organ MSOF, more difficulty is brought to its treatment.
In consideration of it, replenishment of blood content is the most basic and primary measure for the treatment of shock, it is also to correct group caused by shock
Knit the key of Low perfusion and anaerobic condition.Timely, quick, enough benefits will be carried out at first aid scene to patients with hemorrhagic shock
Liquid.The quick infusion that pressurizes is clinically conventional method, and anti-hemorrhagic shock is most simple, maximally effective means are exactly quick mend
Liquid.Required in the rescue of battlefield rules of the armies such as the U.S., Israel the first rescue stage and after send can be to wound of losing blood in way
Member carries out quick liquid supplement, to stablize the condition of the injury.According to statistics, the line severe wounded for having 50% are required for soon before being given treatment to
Fast liquid supplement.Dilatation speed is emphasized during rescue hypovolemic shock, rather than emphasizes the total amount infusing, transfuse blood, is particularly
The salvage success rate of shock can be improved by obtaining timely quick infusion treatment after wound before 2h.The shock disease of blood volume wretched insufficiency
Transfusion speed in people, 1~2h of rescue time is per minute should be in more than 15ml.Because, if inputting 2000 milliliters of liquid in 2h
Body, so that it may make a transfusion patient take a turn for the better rapidly, if inputting at a slow speed, makes 2000 milliliters of liquid slowly be inputted in 24h, then to stopping
It is gram of no avail.Therefore, the key that transfusion speed is successful rescue is improved.
Rapidly input decoction and blood and Related product to realize, existing infusion device for example infusion pump, infusion controller,
Inflating bag etc. is achieved the goal by applying active force to infusion pipeline, infusion bag.Wherein infusion pump is with driven by power, with wriggling
Pump or air driven pump are extruded pipeline；Infusion controller is infused with driven by power using gravity；And inflating bag is non-machine
Tool product, to inflating bag parcel infusion bag is being inflated by user using preceding, standby using being deflated again after finishing.And this
Three kinds of products have deficiency, and infusion pump, infusion controller need electric power, it is impossible to use for a long time, infusion controller utilizes liquid
Self gravitation is, it is necessary to which perching to use, it is impossible to which realization rapidly inputs decoction, and inflating bag needs manually to fill repeatedly
Gas, deflation, take time and effort.
In actual life, the burst such as field exploration, traffic accident, natural calamity, state of war place is unpredictable, scene
No electric power is also tended to, the manpower of rescue, time, efficiency are very precious, existing medical product is not enough to solve these situations.
The content of the invention
It is a primary object of the present invention to overcome the shortcoming and deficiency of prior art to add there is provided a kind of transfusion of mechanical
