Abstract
The utility model relates to a medical auto-monitor for the transfusion in the technical field of the medical appliance, comprising a mechanical part and a prewarning circuit part controlled by a multiple-path switch connected in parallel. The mechanical part is an elastic gravity transducing structure. A multiple-path circuit connected in parallel in the circuit part is connected with the prewarning circuit in parallel. The utility model does not alter the hanging mode of the original liquid bottle. The utility model adopts lever spring hanging type supporting. The functions that the infusion dosage is visually displayed, the infusion alarm is automatically controlled, and the infusion is arranged arbitrarily are implemented. The utility model has the advantages of simple structure, and small volume. The utility model can be conveniently merged into the common ward paging system of the existing hospital. Any auxiliary device is not required to increase.
Description
This utility model belongs to technical field of medical instruments, further relates to a kind of medical transfusion automatic monitoring device.
At present, monitoring to the patient infusion process, it mainly is the observation at any time that relies on the nurse, this method for supervising can or be busy with one's work because of medical personnel's inadvertent, incurs loss through delay the timely processing after liquid adds or liquid is totally lost, thereby cause air embolism, as for observing, can cause the ward management confusion again, the influence treatment by the personnel of accompanying and serving.In addition, what of amount of infusion in the bottle are perusal by the people fully, and are at some in particular cases (light is darker, and the observation people is when infusion bottle is far away), both inconvenient, also not directly perceived.
At above problem, it is a kind of simple in structure that this utility model provides, and demonstration of liquid collecting amount and automatic warning function are in the medical transfusion automatic monitoring device of one.
This utility model comprises mechanical part and circuit part, and mechanical part is for elasticity gravity sensing arrangement, multi-channel parallel circuit and early warning circuit and connect in the circuit part.
The utility model will be further described below in conjunction with accompanying drawing
Fig. 1 is an overall structure sketch map of the present utility model.
Fig. 2 is the structural representation of this utility model base plate.
Fig. 3 is the structural representation of this utility model movable contact.
Fig. 4 is this utility model circuit part electrical schematic diagram.
This utility model is connect by upper plate 3 and base plate 4 usefulness bolts 8 and forms, and the position that takes over, center has curved channel 12 on the base plate 4, with the movement locus of restriction movable contact 16.The lower right of base plate 4 has unthreaded hole, so that rotating shaft 15 to be installed, be connected with lever arm of force 11 on it, also have straight shape conduit 13 on the lever arm of force 11, and movable slider 14 is installed, and be connected with lower draw-bar 9 on the slide block 14, be used to hang infusion bottle, whole lever arm of force 11 on its end points by spring 2 with on hook 1 be connected, link up with 1 and hang on the drip stand.
One end of spring 2 of the present utility model is fixed on the base plate 4, and the other end is fixed on the end top of lever moving arm 11, and lower draw-bar 9 is connected on the slide block 14 of lever resistance arm.The end points of lever moving arm is connected with a movable contact 16, be fan-shaped at least ten stationary contacts 17 that are distributed with according to lever balance position difference on the base plate 4, in the arc archway of base plate 4, movable contact 16 is housed, it joins by curved channel 12 and lever arm of force 1, on upper plate 3,12 light emitting diodes 5 are housed, all light emitting diodes 5 are parallel connection, negative pole is all connected with the negative pole of power supply 18, wherein the 1st, the positive pole of the 12nd diode links by on and off switch 7 and positive source, the positive pole of all the other 10 diodes links with ten stationary contacts 17 respectively, between each stationary contact 17 and buzzer 10, be connected in series one road toggle switch 6, constitute 10 road paralleling switch control circuits, constitute by ten road toggle switches 6 that are contained in the supervising device downside corresponding to 10 stationary contacts 17.
This utility model is finished as follows to the monitoring of infusion process: do not change old liquid bottle hang, adopt arm spring suspension supporting arrangement, only add this device between carriage and infusion bottle.In this infusion process, liquid measure constantly reduces in the liquid bottle, bring tension spring constantly to shorten, by the mechanical force moment equilibrium principle, the lever balance angle constantly changes, so, the vertical movable contact of lever arm of force is fan-shaped distribution with connection, characterizes ten groups of stationary contacts of different liquid measures, and the position of stationary contact requires artificial the demarcation according to the liquid measure of reality, thereby light corresponding light emitting diode, to realize the function that shows directly perceived, light emitting diode 5 has 12, and wherein the 1st and 12 is green, all the other are red, and how much what observe liquid measure is to realize according to the relative position of red LED and two green LED.Among circuit, and the toggle switch that connects, 1 to 10 the tunnel stir the ON of key or ten different liquid measure shelves of OFF state representation from 0% to 100%, group key closure of deciding the liquid measure correspondence will be proposed, in case amount of infusion reaches the relevant position, to trigger the buzzer loop, sound and light alarm will be provided, can reach the purpose of setting the warning liquid measure.The switch of whole device circuit is realized by total power switch 7.In addition, this triggering signal also can be connected to hospital call loop commonly used by parallel way, reaches transfusion and finishes the function of automatic paging.
Use this medical transfusion automatic monitoring device, as long as the call signal lights by placing nurses' office and the alarm of electric bell, just can recognize patient's transfusion situation, give timely nursing, both alleviated nurse's labor intensity, also avoided because of observing the untimely unnecessary malpractice that may cause.
