Background technology
Mostly adopt manual observation infusion process during current patient fluid infusion, when appearance of infusing is abnormal or transfusion closes to an end, transfusion outpatient or nurse personnel find rear nurse call.When the patient infused is in sleep or comatose state, if tube for transfusion is oppressed, especially transfusion outpatient does not nurse personnel or nurse personnel at one's side when not having a Timeliness coverage, transfusion process can be affected, or when adopting full light proofing infusion apparatus, transfusion medicated bag and conduit system are placed in shade, or when transfusion bag and conduit adopt lucifuge dark material, the speed of dripping in the progress of transfusion, dropper is observed and is all comparatively bothered.Lucifuge is needed to carry out during clinical vein injection portion medicine, as: fluoroquinolones is as levofloxacin magnitude antibiotic, nifedipine class medicine is as cardiovascular drugs such as nifedipines, Some Hormones class medicine is as estradiol benzoate etc., antituberculosis drugs is as sodium aminosalicylate etc., water soluble vitamins, part chemotherapeutics is as platinum-based chemotherapy medicine etc., , transfusion bag must be done lucifuge process by these medicines in infusion process, adopt at present mostly and local or overall minimum observation transparency are set on transfusion device to observe transfusion condition, reduce the impact of medicament decomposes as far as possible.Normal employing arranges shade or add the method for lucifuge agent to carry out lucifugal infusion in the material of medicine bottle and tube for transfusion outside medicine bottle, decomposes to reduce medicine.The lucifuge scope of the light proofing infusion apparatus of current national regulation is 290nm-450nm.Yellow wavelengths is close to HONGGUANG, light quantum energy is less, also less to medicinal liquid chemolysis ability, therefore select dark yellow and brown as transfusion device lucifuge color, common laboratory needs the reagent of lucifuge and medicine also all to select brown bottle to store (brown toning=Huang+orange+black).The lucifuge agent that early stage light proofing infusion apparatus adopts directly contacts with medicinal liquid, and in infusion process, lucifuge agent can enter human body, health risk along with medicinal liquid; Shading bell-type lucifugal infusion method has only carried out lucifuge to medicine bottle etc., and still have by the possibility of illumination at infusion pipeline Chinese medicine, therefore drug effect can reduce, and is unfavorable for observing transfusion condition.Complete black light-shading effect is best, but is unfavorable for equally observing transfusion condition and controlling transfusion process.

Contrast prior art, the beneficial effects of the utility model are: be convenient to observe transfusion condition and control transfusion process, especially when patient's sleep or stupor, tube for transfusion is oppressed, or, when adopting full light proofing infusion apparatus, whether liquid drop speed and prompting transfusion terminate to adopt native system to know in time, the multiple display unit composition console of native system, the transfusion condition of multiple patient can be observed simultaneously, and obtain the prompting of abnormal conditions, improve the work efficiency of nursing staff, also reduce the trouble of entourage.
Detailed description of the invention
Below in conjunction with drawings and Examples, this utility model is described in detail, also describe technical problem and the beneficial effect of technical solutions of the utility model solution simultaneously, it is to be noted, described embodiment is only intended to be convenient to understanding of the present utility model, and does not play any restriction effect to it.
The embodiment of the transfusion system that a kind of band as shown in Figure 1 statistics have shown, comprising:
Transfusion bag 1; Breather 2; Tube for transfusion 3; Dropper 4; Actuator 5; Drip fast sensor 6; Asv sensor 7; Hold assembly 8; Display unit 9.
Transfusion bag 1 is connected with tube for transfusion 3, and tube for transfusion is provided with dropper 4 and actuator 5; Breather 2 is connected with transfusion bag 1;
Drip fast sensor 6 and be attached at dropper 4 outer surface by hold assembly 8, for obtaining a speed of drop in dropper 4; Drip fast sensor 6 and comprise the pick-up unit, a/d converter, the signal output port that are connected successively, also comprise supply module; Pick-up unit obtain drop low time regular microvibration (frequency of this vibration time window in relatively steadily and distinguish over the frequency of environmental perturbation, that pick-up unit can detect the frequency of this microvibration to judge transfusion speed), and this signal is converted to digital signal sends to display unit 9 by signal output interface; Display unit 9 will drip speed and show on a display screen by analog picture, drive speaker to send warning when dripping the controller of display unit 9 when speed is greater than or less than normal level.
Asv sensor 7 is arranged on the opening that breather 2 contacts with air; For obtaining the airflow signal at breather mouth of pipe place, and this signal is converted to digital signal sends to display unit 9 by signal output interface, asv sensor 7 comprises the airflow sensor device, a/d converter, the signal output port that connect successively, also comprises supply module.Airflow sensor device can adopt the digital pneumatic sensor in Honeywell etc.
Display unit 9 drips the information such as speed, time for display, comprises display screen, control panel, switch, power supply unit, signal input interface, control unit, speaker; Described signal input interface is connected with control unit, and control unit is connected with display screen, control panel, speaker, and switch is connected with control unit with power supply unit.Speaker terminates for pointing out transfusion, when asv sensor 7 detects that breather air-flow is tending towards constant, illustrate that transfusion bag Chinese medicine liquid level is lower than transfusion needle position, transfusion closes to an end, now the control unit of display unit 9 receives the signal that asv sensor 7 is sent, control unit is decoded to this signal and is judged, then drives speaker to provide auditory tone cues.Control unit can adopt single-chip microcomputer or the mode such as integrated chip or FPGA to realize operation.
Pick-up unit can adopt micro-vibration sensor, as omnirange model (MVS0608.02/MVS0409.02) one direction model (MVS1006.01), or adopts piezoelectric velocity sensor etc.Pick-up unit also can adopt other types drip fast sensor as photo-electric drip fast sensor,
The signal output port dripping fast sensor 6 respective with asv sensor 7 is connected by the signal input interface of wired or wireless mode with display unit 9.
The mode that the power supply suggestion of dripping fast sensor 6 and asv sensor 7 adopts built-in electricity accumulating unit and reserve battery to combine is carried out independently-powered separately, in infusion process, reserve battery can be utilized power supply is continued, to reduce because power-off is on the impact of infusion monitoring result when electricity accumulating unit electricity is finished.
As preferably, described dropper 4 is Murphy's burettes;
When needs carry out lucifugal infusion, described transfusion bag 1, breather 2, tube for transfusion 3, dropper 4 adopt disposable opaque PVC transfusion device external member, and such as described transfusion bag 1, breather 2, tube for transfusion 3, dropper 4 adopt PVC and lucifuge color mother to mix in the molten state according to the ratio of 1:1000 ~ 1300.Or described transfusion bag 1, breather 2, tube for transfusion 3, dropper 4, a fast sensor 6 when needing to carry out lucifugal infusion; It is inner that asv sensor 7 is positioned over light tight shade.
The signal input interface of display unit 9 is ZigBee wireless communication interfaces.The signal output port dripping fast sensor 6 and asv sensor 7 is the ZigBee wireless communication interface corresponded.
As preferably, native system also comprises infusion support, and transfusion bag 1 is hung on infusion support top, and dropper 4 is fixed in the vertical rod of infusion support relevant position by hold assembly 8.More stable effect can be played like this.
As preferably, native system also comprises console, is made up of multiple display unit, and console also can comprise overall outer cage and unified supply module etc.Medical personnel can observe the transfusion condition of multiple patient simultaneously, and obtain the prompting of abnormal conditions.
