Preferably, infusion pump also comprises: air bubble sensor, and be attached on the surface of tube for transfusion, and be electrically connected with described processor by lead, be used to detect whether have bubble in the tube for transfusion.
Preferably, alarm device is an audible-visual annunciator.
Preferably, also be provided with status indicator lamp on the pump housing, this status indicator lamp receives the control signal of from processor, is used to indicate the duty of infusion pump.
Preferably, also be provided with start stop switch on the pump housing, this start stop switch is connected with processor, is used to control the start and stop of infusion pump.
The present invention has following beneficial effect:
1. the present invention is provided with pressure transducer by the upstream in infusion pump, and when upstream occlusion occurring, infusion pump will start alarm device, and with sound and light alarm and the operation that stops to infuse.Thereby avoid incuring loss through delay the problem of patient treatment, improved the safety of transfusion because of the obstruction of tube for transfusion upstream.
2. simultaneously, the present invention also is provided with pressure transducer and air bubble sensor by the downstream in infusion pump, make in infusion process, when medicinal liquid that infusion pump detects upstream and downstream block and tube for transfusion in the situations such as bubble that whether have, will report to the police and stop transfusion, thereby improved the safety of transfusion, simultaneously, also saved the manpower nurse in the infusion process.
4. in addition, infusion pump size provided by the present invention is quite little, cost is low, simple to operate.
Description of drawings
Accompanying drawing described herein is used to provide further understanding of the present invention, constitutes the application's a part, and illustrative examples of the present invention and explanation thereof are used to explain the present invention, do not constitute improper qualification of the present invention.In the accompanying drawings:
Fig. 1 shows the structural representation according to the infusion pump of first embodiment of the invention;
Fig. 2 shows the structural representation according to the infusion pump of second embodiment of the invention;
The specific embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the present invention in detail.
Fig. 1 shows the infusion pump according to first embodiment of the invention, as shown in the figure, the pump housing 10 inside are provided with a U type transfusion tube seat 20 that is used to place tube for transfusion, and the outer surface of tube for transfusion is fitted in the transfusion tube seat 20, transfusion tube seat 20 crosses the whole pump housing 10, and its length and the pump housing 10 are isometric.The transfusion tube seat 20 of the pump housing 10 inside is provided with a driving device 30, and this driving device 30 is a pressurizing unit, by the sidewall that pushes tube for transfusion placed thereon liquid in the tube for transfusion is exported from outfan.Also be provided with first pressure transducer 40 on the transfusion tube seat 20 of the pump housing 10 inside, it is positioned on one section transfusion tube seat 20 before the driving device 30, the force value that is used to gather infusion pump liquid input, and first pressure transducer 40 is close on the sidewall with tube for transfusion.First pressure transducer is along with the increase of tube for transfusion internal liquid pressure and the expansion and the contraction phase of minimizing tube for transfusion elastic wall should produce a pressure signal in ground, this pressure signal is supplied with processor 50 by lead, and processor 50 is arranged on the intravital circuit board of pump.Processor 50 also is electrically connected with alarm device 60.
In the work process of infusion pump, first pressure transducer 40 passes to processor 50 with the upstream pressure value of the tube for transfusion that collects, processor 50 is compared the force value that is collected with default force value, if when the force value of being gathered exceeds the threshold value of warning, processor 50 cuts out driving device 30, and starts alarm device 60.In the present embodiment, when upstream occlusion appearred in tube for transfusion, infusion pump will produce the upstream occlusion sound and light alarm, and execution stops transfusion operation.Thereby can in time remind patient and medical personnel, avoid incuring loss through delay patient treatment because of the obstruction of infusion pipeline.
Fig. 2 shows the infusion pump according to second embodiment of the invention, and this infusion pump also is provided with the air bubble sensor 70 and second pressure transducer 80 on the basis of first embodiment.Air bubble sensor 70 is connected with processor 50 by lead with second pressure transducer 80, also the pressure signal of being gathered is supplied with processor 50, the processing method of 50 pairs of received pressure signals of processor is identical with first embodiment, like this, when the infusion pump outfan takes place to block, infusion pump will produce the downstream block sound and light alarm, and execution stops transfusion operation.
As shown in Figure 2, before infusion pump work, at first open the pump door of infusion pump, the tube for transfusion 90 that will have an elastic wall is packed in the infusion pump from top to bottom, and tube for transfusion 90 is successively through first pressure transducer 40, driving device 30, air bubble sensor 70 and second pressure transducer 80.The air bubble sensor 70 and second pressure transducer 80 all are connected to processor 50.
In the infusion pump work process, first pressure transducer 40 is the fluid pressure imported of monitoring transfusion pipe in real time, prevents that the upstream medicinal liquid from blocking.80 of second pressure transducers are the fluid pressure of monitoring transfusion pipe outfan in real time, prevents the obstruction of downstream medicinal liquid.When stopping, remind patient and medical personnel by sound and light alarm, and stop transfusion if the medicinal liquid obstruction takes place for upstream or downstream.Air bubble sensor 70 is used for detecting the bubble of tube for transfusion, and air bubble sensor 70 passes to processor 50 with detection signal, judges when in the tube for transfusion bubble being arranged when processor 50, and starting alarm will report to the police, and stops transfusion immediately.
On the infusion pump of the foregoing description, status indicator lamp and start stop switch can also be set.Status indicator lamp receives the control signal of from processor, is used to indicate the duty of infusion pump.When the infusion pump operate as normal, the normal display lamp of status indicator lamp is bright, when infusion pump is in alarm condition, and the flicker of the alarm lamp of status indicator lamp.Start stop switch is connected with processor, is used to control the start and stop of infusion pump.Patient can be in infusion process whenever press start stop switch, then status indicator lamp extinguishes, infusion pump quits work.
The above is the preferred embodiments of the present invention only, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
