Abstract
The invention discloses an infusion pump with an occlusion alarm device, which comprises a pump body bracket, a peristaltic pump installed on the pump body bracket, a motor for driving the peristaltic pump and an occlusion alarm device, wherein the occlusion alarm device comprises a sensor and a signal processing module, and the sensor is used for detecting the rotation speed signals of the peristaltic pump and outputting the rotation speed signals to the signal processing module; and the sensor is installed on one end surface of the rotating shaft of the peristaltic pump. By arranging the occlusion alarm device, the invention can detect the rotating condition of the peristaltic pump, and can send out alarm signals in time when the peristaltic pump stalls or the rotation speed of the peristaltic pump drops due to the belt creep or fracture or other causes, thereby reducing the potential safety hazard in the transfusion process.
Description
Technical field
The present invention relates to a kind of medium be introduced the medical apparatus and instruments of human body, specifically relate to a kind of infusion pump.
Background technology
Infusion pump is a kind of device of safe, accurate control transfusion.Traditional infusion mode utilizes liquid potential energy to be used as power, and be difficult to control transfusion speed and amount of infusion steadily in the long term, and infusion pump can satisfy high accuracy and the occasion requirement of transfusion fast.As shown in Figure 1, be fixed with motor 2 on the pump housing support 1 of infusion pump, motor 2 drives drivewheel 3 rotations, drivewheel 3 drives driven pulley 5 rotations by belt 4, thereby drive rotating shaft 6 rotations of peristaltic pump, at this moment the lateral surface that is installed in a plurality of eccentrics 7 in the rotating shaft 6 forms the waveform motion, thereby promotes to be pressed on the interior liquid flow of tube for transfusion of lateral surface.The problem that existing infusion pump exists is, because infusion pump is to control the flow, flow velocity etc. of transfusion by the speed of regulating motor, if fault has appearred in the transmission that motor 2 and rotating shaft are 6, as skid, reason such as belt disengaging causes the motor rotation and peristaltic pump does not rotate or rotary speed when very slow, will bring the safety problem of transfusion, form medical hidden danger.
Summary of the invention
The technical problem to be solved in the present invention is to propose a kind of infusion pump with occlusion alarm device, can in time find peristaltic pump holddown phenomenon, eliminates the potential safety hazard that causes owing to the holddown reason in the infusion process.
Technical problem of the present invention is solved by the following technical programs.
This infusion pump with occlusion alarm device comprises pump housing support, is installed in the peristaltic pump on the pump housing support, the motor of driving peristaltic pump; Also comprise occlusion alarm device; Described occlusion alarm device comprises pick off, signal processing module, and described pick off is used to detect the tach signal of peristaltic pump, and this tach signal is exported to signal processing module.
Further, in the above-mentioned infusion pump with occlusion alarm device, described pick off is installed on this body support frame, be positioned at an end of peristaltic pump rotating shaft.
Pass through drivewheel, belt and driven pulley transmission between described motor and the peristaltic pump.
Described signal processing module comprises signal processing circuit, processor controls and audible-visual annunciator, the input of described signal processing circuit is connected with the outfan of pick off, the outfan of described signal processing circuit is connected with the input of processor controls, and the input of described audible-visual annunciator is connected with the outfan of processor controls.
The outfan of described processor controls also is connected with motor.
The present invention is compared with the prior art the beneficial effect that is had: prior art is only carried out feedback control to the revolution of motor, and the present invention is provided with occlusion alarm device, can detect the rotation situation of peristaltic pump, when peristaltic pump causes stall owing to reasons such as belt creep or fractures, can send alarm signal in time, thus the potential safety hazard in avoiding infusing.The rotating speed induction apparatus is installed in the axial end of peristaltic pump, does not influence the physical dimension of the whole pump housing, and can directly detect the rotating speed of peristaltic pump.
Description of drawings
Fig. 1 is the structural representation of the specific embodiment;
Fig. 2 is the functional block diagram of the occlusion alarm device in the specific embodiment.
The specific embodiment
A kind of infusion pump, as shown in Figure 1, identical with existing infusion pump is to comprise pump housing support 1, motor 2, drivewheel 3, belt 4, driven pulley 5, rotating shaft 6, eccentric 7.Motor 2 drives drivewheel 3 rotations, drivewheel 3 drives driven pulley 5 rotations by belt 4, driven pulley drives rotating shaft 6 rotations of peristaltic pump, after rotating shaft 6 rotations, the lateral surface that is installed in a plurality of eccentrics 7 in the rotating shaft 6 forms the waveform motion, thereby promotes to be pressed on the interior liquid flow of tube for transfusion of lateral surface.Infusion pump also is provided with control unit, is used to control starting and stopping, the rotating speed size of motor.
In the present embodiment, also be provided with occlusion alarm device.
As shown in Figure 1, on an end of the rotating shaft 6 of peristaltic pump, pump housing support, also be provided with electromagnetic type speed probe 8, be used to detect the speed conditions of driven spindle 6, the operation principle of pick off 8 is a prior art, also can adopt various Hall elements, photoelectric sensor.Pick off 8 is installed in an end of driven spindle 6, thereby can directly detect the rotating speed of rotating shaft 6, and does not influence whole transfusion pump structure, and is easy for installation.As shown in Figure 2, occlusion alarm device comprises magnetoelectric transducer module 100 and signal processing module, and signal processing module comprises signal processing circuit 200, processor controls 300 and audible-visual annunciator 400.Magnetoelectric transducer module 100 is gathered the tach signal of rotating shaft 6 by the pick off 8 that is installed in rotating shaft 6 one ends, and tach signal sent into signal processing circuit 200 is amplified, comparison process, if abnormal conditions appear in the rotating speed of rotating shaft 6, such as stopping operating or rotating speed drops to the limit low value of setting, then output signal to processor controls 300, processor controls control 300 starts audible-visual annunciator 400 and sends the sound and light alarm signal.Simultaneously, processor controls 300 also is connected with motor 2, outputs signal to the rotation that motor 2 stops motor 2, prevents that idle running of holddown rear motor or motor overload from damaging.
Above content be in conjunction with concrete preferred implementation to further describing that the present invention did, can not assert that concrete enforcement of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
