Abstract
The present invention discloses a kind of high pressure injector self adaptation stream speed control method, in injection process, passes through the pressure-detecting device in syringe, real-time detection injection pressure P, if observed pressure P is greater than limiting pressure P0, reduces flow velocity and injected, preferably injection speed is in 1ml/s or less;If observed pressure P, which is greater than, interrupts pressure P1, injection is interrupted;When being injected with low flow velocity, whether detection observed pressure P, which is less than, is restored pressure P2, if P is less than P2, it is then injected by nominal flow rate V, otherwise continues to inject with low flow velocity, greatly facilitate the use of medical staff, it ensure that injection safety, patient's pain is alleviated, design is scientific and reasonable, easy to use.
Description
Technical field:
The present invention relates to a kind of high pressure injector self adaptation stream speed control methods, belong to high pressure injector technical field.
Background technique:
For patient when doing CT scan, the image effect to make is apparent, generally requires to people's internal injection contrast agent.
In injection, syringe can be injected with the normal speed that medical staff sets.But in the human body blood vessel access obstruction or
The disposable unit of connection limits contrast agent flow, and syringe can rise.If do not handled in time, angiorrhoxis will cause
Or the serious problems such as disposable unit damage, injection safety is influenced, patient health is endangered.
Existing high pressure injector can continue the speed according to setting, be injected when injecting contrast agent.Occurring
When obstruction, often medical staff cannot have found and react in time, cause serious consequence, endanger patient health.There are also one
A little high pressure injectors can be with real-time detection to pressure when injecting contrast agent, and is handled for the obstructing problem occurred,
But method is usually directly to stop injection.Although it is possible to prevente effectively from serious consequence occurs.But obstruction only occurs in one sometimes
Moment may maintain a period of time obstructing problem that will disappear, if stopped injection at this time, need medical staff to high pressure
Syringe resets and starts, and increases workload.
Summary of the invention:
The present invention is directed to technical problems to be solved, proposes a kind of high pressure injector self adaptation stream speed control method, infuses
During penetrating, by the pressure-detecting device in syringe, real-time detection injection pressure P, if observed pressure P is greater than limit pressure
Power P0 then reduces flow velocity and is injected, and preferably injection speed is in 1ml/s or less;If observed pressure P, which is greater than, interrupts pressure P1,
Then interrupt injection;When being injected with low flow velocity, whether detection observed pressure P, which is less than, is restored pressure P2, if P is less than P2, is pressed
Nominal flow rate V is injected, and otherwise continues to inject with low flow velocity, greatly facilitates the use of medical staff, ensure that injection
Safety alleviates patient's pain, and design is scientific and reasonable, easy to use.
A kind of high pressure injector self adaptation stream speed control method, the control method is: starting high pressure injector, setting
Nominal flow rate V and limiting pressure P0, system-computed show that interrupting pressure P1 and injection restores pressure P2;After the completion of setting, start
Injection: in injection process, pass through the pressure-detecting device in syringe, real-time detection injection pressure P, if observed pressure P is big
In limiting pressure P0, then reduces flow velocity and injected, preferably injection speed is in 1ml/s or less;It is interrupted if observed pressure P is greater than
Pressure P1 then interrupts injection;When being injected with low flow velocity, whether detection observed pressure P, which is less than, is restored pressure P2, if P is less than
P2 is then injected by nominal flow rate V, otherwise continues to inject with low flow velocity.
As the preferably described limiting pressure P0 between 100~300psi, pressure P1=(1.1~1.5) * is interrupted in injection
P0;Injection restores pressure P2=(0.6~0.8) P0.
Beneficial effects of the present invention: in injection process of the present invention, pass through the pressure-detecting device in syringe, real-time detection
Injection pressure P reduces flow velocity and is injected, preferably injection speed is in 1ml/s if observed pressure P is greater than limiting pressure P0
Below;If observed pressure P, which is greater than, interrupts pressure P1, injection is interrupted;When being injected with low flow velocity, detection observed pressure P is
The no recovery pressure P2 that is less than is injected by nominal flow rate V if P is less than P2, is otherwise continued to be injected with low flow velocity, pole
The use for facilitating medical staff greatly, ensure that injection safety, alleviate patient's pain, design is scientific and reasonable, easy to use.
Detailed description of the invention:
Detailed description will be given by the following detailed implementation and drawings by the present invention for ease of explanation,.
Fig. 1 is control method schematic diagram of the invention.
Specific embodiment:
In order to make the objectives, technical solutions and advantages of the present invention clearer, below by shown in the accompanying drawings specific
Embodiment describes the present invention.However, it should be understood that these descriptions are merely illustrative, and it is not intended to limit model of the invention
It encloses.In addition, in the following description, descriptions of well-known structures and technologies are omitted, it is of the invention to avoid unnecessarily obscuring
Concept.
As shown in Figure 1, a kind of high pressure injector self adaptation stream speed control method, the control method is: starting high pressure
Syringe, sets nominal flow rate V and limiting pressure P0, and system-computed show that interrupting pressure P1 and injection restores pressure P2;Setting
After the completion, start to inject: during penetrating, passing through the pressure-detecting device in syringe, real-time detection injection pressure P, such as fruit
Measuring pressure P is greater than limiting pressure P0, then reduces flow velocity and injected, preferably injection speed is in 1ml/s or less;If observed pressure
P, which is greater than, interrupts pressure P1, then interrupts injection;When being injected with low flow velocity, whether detection observed pressure P, which is less than, is restored pressure P2,
If P is less than P2, is injected by nominal flow rate V, otherwise continue to inject with low flow velocity.
As the preferably described limiting pressure P0 between 100~300psi, pressure P1=(1.1~1.5) * is interrupted in injection
P0;Injection restores pressure P2=(0.6~0.8) P0.
