Description
Technical field
The utility model is related to technical field of medical instruments, and in particular to a kind of micro-injection with the uniform velocity stabilization function
Pump.
Background technology
It is uniform micro that micro-injection pump is that be commonly used in clinical treatment and life science a kind of is carried out for a long time
The instrument of injection.Compared with manual injection, micro-injection pump has the advantage that：(1) can long-time constant speed injection, strictly to tie up
Hold medicine required concentration in blood；(2) curative effect of medication and therapeutic quality are improved.
State Intellectual Property Office disclosed a kind of " closed high precision micro syringe pump ", patent on 2 25th, 2015
Number be ZL201420228132.5, the micro-injection pump include cylinder and for drive cylinder piston carry out straight reciprocating motion
Air machinery；Cylinder tail end is provided with for detecting in cylinder the pressure sensor of pressure and for detecting that cylinder piston is moved
The displacement transducer of amount.The micro-injection pump is carried out before straight reciprocating motion, cylinder piston using air pump pusher cylinder piston
The piston with being connected syringe is held, so that the piston movement of pushing syringe, improves the stability of injection to a certain extent,
But the uniform and stable property of injection still has much room for improvement.
Utility model content
The utility model aims to provide a kind of micro-injection pump with the uniform velocity stabilization function, makes the at the uniform velocity stability of injection
Further improve.
Therefore, the technical scheme that is used of the utility model for：A kind of micro-injection pump with the uniform velocity stabilization function, bag
Include air pump, cylinder, cylinder piston, data processor, the first pressure sensor for detecting pressure in cylinder and for detecting
The displacement transducer of cylinder piston amount of movement, it is characterised in that：Also include being used for the second pressure for detecting the cylinder piston resistance of motion
Force snesor, the first pressure sensor, displacement transducer, second pressure sensor, air pump are electric with data processor respectively
Connection.
As the preferred of such scheme, in addition to the alarm electrically connected with the data processor, when cylinder piston with
Syringe comes off, and the cylinder piston resistance of motion for detecting second pressure sensor is less than the normal range of operation value of setting
When, or when syringe is blocked, the cylinder piston resistance of motion that second pressure sensor is detected is more than the normal work of setting
During value range, alarm can send alarm signal prompting in time；The warning function for coming off or blocking by setting up syringe, enters
The security that one step increase is used.
The beneficial effects of the utility model：At the second pressure sensor being connected by setting up with data processor, data
Reason device is analyzed the real-time detection numerical value of three sensors, determines inner pressure of air cylinder, the cylinder piston resistance of motion and piston
Curved line relation change between movement velocity, carries out adjustment of rotational speed and control to air pump in advance, so that accurately control piston movement
Speed is uniform and stable.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below by embodiment and with reference to accompanying drawing, the utility model is described in further detail：
As shown in figure 1, a kind of micro-injection pump with the uniform velocity stabilization function, by air pump 1, cylinder 2, cylinder piston 3, number
According to processor, the first pressure sensor 4 for detecting pressure in cylinder 2 and the displacement for detecting the amount of movement of cylinder piston 3
Sensor 5, for detecting that the second pressure sensor 6 of the resistance of motion of cylinder piston 3 is constituted.
First pressure sensor 4, displacement transducer 5, second pressure sensor 6, air pump 1 are electrically connected with data processor respectively
Connect.First pressure sensor 4, displacement transducer 5, second pressure sensor 6 are used for real-time data collection, and pass at data
Manage device and carry out analysis calculating, and automatically control the rotating speed of air pump 1.
Preferably, in addition to data processor the alarm electrically connected.When cylinder piston 3 and syringe come off, make
When the resistance of motion of cylinder piston 3 that two pressure sensors 6 are detected is less than the normal range of operation value of setting, alarm is sent out in time
Go out alarm signal prompting；Or, when syringe is blocked, the resistance of motion of cylinder piston 3 that second pressure sensor 6 is detected is more than
During the normal range of operation value of setting, alarm can also send alarm signal prompting in time.
