Description
Technical field
This utility model relates to a kind of medical infusion pump, particularly to a kind of analgesia pump.
Background technology
Self-controlled electronic analgesic transfusion pump is that one commonly used in clinical treatment and life science is carried out for a long time
The uniformly instrument of micro-injection.It is used to special analgesic infusion device, under microprocessor controls, by the pump housing by analgesic
Liquid is pushed through in the patient by certain flow velocity.Need clinically according to medicine different with the pain situation of patient be equipped with different
Infusion dosage and infusion velocity.Along with the development of medical skill, people to the safety of the infusion pump of this trace infusion,
Reliability is had higher requirement.Therefore, the research to Self-controlled electronic analgesic transfusion pump device has great practical value.
At present, trace infusion pump both domestic and external, the difficult point faced is that not and cost is higher for precision.Numerous enterprises and scientific research institution are all
Put into the research of the trace infusion pump of infusion velocity controllable precise, design and manufacture.Traditional infusion model uses to be hung
Bottle transfusion, it needs to observe with eye, manually rolls clip and control the flow velocity of medicinal liquid, it is impossible to accurately control infusion velocity；Intelligence
Although energy infusion pump automaticity is higher, but they are substantially the rotating speed using software to control motor and realize infusion
The control of speed, the fault-tolerance not only resulting in instrument is poor, and the highest to the performance requirement of motor, thus cost is the most inclined
High.
Utility model content
The purpose of this utility model is to provide a kind of adjustable electronic analgesia pump, its simple in construction, cost sole, and makes
Used time is easy to control, and precision is high.
The purpose of this utility model is achieved in that a kind of adjustable electronic analgesia pump, including being arranged on base plate
Compression assemblies, described base plate is further opened with groove, in described groove, is provided with tube for transfusion, described compression assemblies includes the end
Seat, described base is provided with driving motor, and the output shaft of described driving motor is in transmission connection worm screw, and worm-drive passes with worm gear
Being dynamically connected, described worm gear is fixedly set on power transmission shaft, and power transmission shaft is arranged on the first support, and described power transmission shaft is machined with wheel
Tooth, described gear teeth meshing connects has driven gear, described driven gear to be fixed on driven shaft, and described driven shaft is arranged on second
On support, described driven shaft being set with cam, described cam connects the pump sheet of extruding tube for transfusion.
During utility model works, by driving motor to drive worm screw to rotate, thus drive worm gear wheel so that with worm gear
The fixing drive axis connected, the processing gear teeth on power transmission shaft drive driven gear to rotate, driven gear rotate drive from
Moving axis rotates, then drives cam rotation, so that pump sheet periodically extruding tube for transfusion realizes transfusion.Compared with prior art,
The beneficial effects of the utility model are, this utility model simple in construction, reduce production cost, and transmission control is convenient can
Lean on, and gear drive realization extruding operation precision is higher.This utility model can be used in sufferer postoperative infusion.
So that extrude convenient, described cam is provided with three, and the motion phase between adjacent two cams is poor
It is 120 °, each cam is respectively connected with pump sheet.
In order to avoid influencing each other between cam so that infuse relatively reliable, between adjacent two cams, it is provided with packing ring.
In order to improve control accuracy further, described base plate being additionally provided with photoelectric sensor, described photoelectric sensor is pacified
It is contained in the sidepiece of driven gear, in order to detect angular displacement and the angular velocity of driven gear.As desired by detection driven tooth
The data of wheel work realize the control driving motor output signal.
So that photoelectric sensor is installed relatively reliable, described photoelectric sensor is fixedly mounted on boss.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
Wherein, 1 base plate, 1a groove, 2 bases, 3 driving motors, 4 boss, 5 photoelectric sensors, 6 worm screws, 7 driven gears, 8
Worm gear, 9 power transmission shafts, the 9a gear teeth, 10 first supports, 11 pump sheets, 12 tube for transfusions, 13 driven shafts, 14 packing rings, 15 cams.
Detailed description of the invention
The adjustable electronic analgesia pump of one as shown in Figure 1, including the compression assemblies being arranged on base plate 1, on base plate 1
Being further opened with groove 1a, be provided with tube for transfusion 12 in groove 1a, compression assemblies includes base 2, and base 2 is provided with driving motor
3, drive the output shaft of motor 3 to be in transmission connection worm screw 6, worm screw 6 transmission is in transmission connection with worm gear 8, and worm gear 8 is fixedly set in transmission
On axle 9, power transmission shaft 9 is arranged on the first support 10, and power transmission shaft 9 is machined with gear teeth 9a, gear teeth 9a engagement connection driven tooth
Wheel 7, driven gear 7 is fixed on driven shaft 13, and driven shaft 13 is installed on the secondary support bracket, and driven shaft 13 is set with cam
15, cam 15 connects and has the pump sheet 11 of extruding tube for transfusion 12, cam 15 is provided with three, and the fortune between adjacent two cams 15
