Abstract
The utility model discloses a blood irradiating cabinet which comprises a cabinet body and a swinging frame arranged in the cabinet body. The base of the swinging frame is connected with a motor through an eccentric wheel, the swinging frame can be driven by the motor to reciprocate on a slide guide rail, and an approach switch is arranged at the position close to the swinging limit position of the swinging frame. When the swinging frame swings normally, the blood irradiating cabinet can output signals. Thus, the situation that error signals are output when the motor is normal and the swinging frame doesn't swing is avoided.
Description
Technical field
This utility model belongs to field of medical, is specifically related to a kind of blood illuminator cabinet.
Background technology
In the time using blood illuminator cabinet to irradiate blood, in order to make blood obtain uniform irradiation, the shelf of putting bags of blood must swing, and blood is fully shaken up in blood bag.The hunting frequency height of shelf directly affect blood illuminator quality, and research shows that frequency is too high or too low and all cannot reach and shake up object, when blood bag volume and blood flow volume one regularly, only have the moderate effect that shakes up that could obtain the best of hunting frequency.So the hunting frequency of blood illuminator cabinet swing span is measured and is accurately controlled particularly important.The hunting frequency measuring method of blood illuminator cabinet swing span is (as marked position as shown in the of 10 in Fig. 1) installation rotation code-disc in motor tail end position normally, when electric machine rotation, drive code-disc to rotate, code-disc is exported pulse again, finally swing span hunting frequency is counted and converted in the pulse of code-disc output.The maximum deficiency of this method is exactly motor 3 and code-disc normal and eccentric 1 or rail plate 4 while having fault, and now motor normal rotation code-disc has signal output, and swing span does not swing, controller receive code-disc signal think by mistake swing normal.
Summary of the invention
The technical problems to be solved in the utility model is that the frequency measurement of blood illuminator cabinet swing span exists rub-out signal, provides a kind of to accurate, the reliable blood illuminator cabinet of swing span frequency measurement.
The technical scheme of this utility model technical solution problem is: a kind of blood illuminator cabinet, comprise cabinet and be arranged on the swing span in cabinet, the base of described swing span is connected with motor through eccentric, swing span moves back and forth under motor drives on rail plate, swings the approaching place of extreme position be provided with approach switch at swing span.
Described approach switch is arranged on swing span bottom by fixed mount and swings the approaching place of extreme position or be arranged on the approaching place of swing extreme position, swing span top.
The approach switch that swing span frequency is detected is arranged on the approaching place of extreme position that swing span swings by blood illuminator cabinet of the present utility model, only having in the time that swing span normally swings could output signal, thus the situation of rub-out signal output while effectively avoiding the normal and swing span of motor not swing.
Brief description of the drawings
In Fig. 1 this utility model blood illuminator cabinet with wave the structural representation of associated components.
Detailed description of the invention
As shown in Figure 1, this utility model blood illuminator cabinet, comprise cabinet (not shown) and be arranged on the swing span 5 in cabinet, the base of described swing span 5 is connected with motor 3 through eccentric 1, motor 3 is fixed in motor fixing seat 2, swing span 5 moves back and forth under motor 3 drives on rail plate 4, swings the approaching place of extreme position and is provided with approach switch 6,7,8,9, as long as an approach switch is set at swing span 5.Approach switch 6,7,8,9 can be fixed on the bottom surface of cabinet or on sidewall with fixed mount 12.In the time that swing span 5 moves to extreme position, (the rightest point or the most left point) approach switch 6,7,8,9 will be exported a high level signal, otherwise in the time leaving extreme position, approach switch will output low level signal.Move back and forth so approaching opening the light and will export rectangular pulse signal, in fact this pulse signal frequency is exactly the hunting frequency of swing span.
Claims (2)
