Description
Technical Field
The utility model relates to the technical field of medical supplies, specifically a built-in flow sensor's injection pump.
Background
In the prior art, along with the improvement of living standard of people, the incidence of diabetes increases, pain treatment is more and more taken into consideration, the injection and analgesic administration of insulin all need the accurate administration of trace, the method that present micropump used is the infusion of open loop control in the in-service use, can not do the measurement to the liquid medicine volume of output, lead to the liquid medicine volume can not give the target in place accurately, often can take place to dose not enough with the problem of overdose, patient's various adverse reactions appear.
If a medicine injection pump capable of accurately controlling the medicine flow can be invented, the problem can be solved, and the medicine injection pump with a built-in flow sensor is provided for the purpose.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a built-in flow sensor's injection pump to solve the problem that proposes among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a built-in flow sensor's injection pump, includes injection pump main part, be provided with eccentric rotor, liquid medicine storage bag, annotate liquid pipe, elastic transmission mechanism, flow sensor and valve block in the injection pump main part.
Preferably, one side of the eccentric rotor is in transmission connection with a valve plate, and one end of the valve plate is connected with an elastic transmission mechanism.
Preferably, one end of the liquid injection pipe is connected with a flow sensor, and the other end of the liquid injection pipe is connected with a liquid medicine storage bag.
Preferably, one side of the eccentric rotor is provided with a liquid medicine storage bag, and one end of the flow sensor is connected with the elastic transmission mechanism.
Compared with the prior art, the beneficial effects of the utility model are that:
1. the sensor mounting part of the utility model is arranged in the middle of the transfusion pipeline, and the liquid bag belongs to disposable consumables, and the driving part belongs to a repeatedly-used instrument, so that the connection between the sensor and the driving pump part is flexible and elastic, which is convenient for disassembly and has practicability;
2. the utility model discloses a micro flow sensor is used in the micro-infusion pump, micro flow sensor's immature in the past, and the demand of micro-pump is not so high, and micro flow sensor maturity improves, and flow sensor installs the micro-infusion pump for the first time on for the calibration as the precision.
Drawings
Fig. 1 is a position distribution diagram of the present invention.
In the figure: 1 eccentric rotor, 2 liquid medicine storage bags, 3 liquid injection pipes, 4 elastic transmission mechanisms, 5 flow sensors, 6 valve plates and 7 liquid medicine injection pump bodies.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the technical scheme in the utility model, all other embodiments that ordinary skilled person in the art obtained under the prerequisite of not making the creative work all belong to the scope of the utility model protection.
Referring to fig. 1, the present invention provides a technical solution: a built-in flow sensor's injection pump, includes injection pump main part 7, is provided with eccentric rotor 1, liquid medicine storage bag 2 on the injection pump main part 7, annotates liquid pipe 3, elastic transmission mechanism 4, flow sensor 5 and valve block 6.
One side of the eccentric rotor 1 is connected with a valve plate 6 in a transmission way, and one end of the valve plate 6 is connected with an elastic transmission mechanism 4.
One end of the liquid injection pipe 3 is connected with a flow sensor 5, and the other end of the liquid injection pipe 3 is connected with a liquid medicine storage bag 2.
One side of the eccentric rotor 1 is provided with a liquid medicine storage bag 2, and one end of a flow sensor 5 is connected with an elastic transmission mechanism 4.
Sensor installation department, install in the centre of infusion pipeline, because the liquid bag belongs to disposable consumptive material, and the drive division belongs to the used instrument repeatedly many times, consequently sensor and drive pump part be connected for soft elastic connection convenient to detach, micro flow sensor is used in the trace transfer pump, micro flow sensor's is immature in the past, the demand of micro pump is not so high, micro flow sensor maturity improves, flow sensor installs for the first time on the trace transfer pump, be used for the calibration as the precision.
The working principle is as follows: the structure of the pump is that the valve plate 6 is driven by the eccentric rotor 1 to move, the sensor is arranged on a conduit of the infusion bag, the infusion pump is communicated with the sensor through elastic connection, the sensor has positive flow and negative flow detection functions, the positive flow direction is measured and detected when the sensor is conducted in the positive direction, and then whether the water is in the required range or not is judged, and correction is not carried out in the range.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
