Description

X-ray radiography automatic medicine-pouring remote control device

This utility model belongs to the new instrument that is used for medical protection in the medical Instrument field.

At present, when carrying out the contrast examination of X line, need the healthcare givers under the direct irradiation of X line, to give the patient injection contrast agent both at home and abroad.As retrograde urography, urethrography, cholangiography, sinus tract radiography etc.The medical worker must be subjected to the infringement of X line, particularly long-term work when injecting contrast agent to patient, endanger bigger.The hospital that has reduces as far as possible and does not even do this contrast examination in order to protect medical worker's health, and undoubtedly, this is not the way of dealing with problems.

The purpose of this utility model provides a kind of remote control unit, and it can make the medical worker across lead glass shielding layer the injection process be carried out remote control, and the protection medical worker avoids the roentgen radiation x infringement.

This device is divided into two parts: emitter and receptor.The infrared transmitter of emitter (29) sends through the synthetic six groups of different infrared pulses of LF multivibrator (27) and carrier frequency oscillation generator (28), to realize that two groups of syringes of remote control separately independently fast, at a slow speed or the speed of injecting that stops.Receptor is converted to the signal of telecommunication with the infrared signal received through infrared receiver tube (9) and infrared reception and demodulator circuit (30), handles the speed of injecting that syringe is controlled in the back through decoding (34).This device can require to preset the injection amount according to the doctor, and when syringe was injected predetermined dose, the diode display lamp of pre-selected amount of medication indication (13) and (17) was luminous, and notifying operation personnel medicinal liquid has been shifted predefined amount onto.When the dose of syringe had all pushed away, the lumination of light emitting diode of limiting alarm (10) and (14) was reported to the police, and cut off the power supply of the motor of pushing syringe motion simultaneously.

The great advantage of this device is to free under the environment that the clinician is penetrated from the X wire spoke, and whole injection process is realized the long-distance remote control operation, and coverage is greater than 7 meters.

This device is easy and simple to handle, only needs receptor is placed on checked patient by the side of, does not need original X line equipment is done any change, also need not increase the clinical examination program, as long as plug in the work of getting final product.

This device is except the clinical examinations such as some internal organs radiographies that are used for retrograde urography, cholangiography, sinus tract radiography, urethrography, lymphography, seminal vesiculography and puncture, also can be used for replacing general intravenous injection etc., to alleviate medical workers.

This installation cost is low, is applicable to all kinds of hospitals and training inspection.

Wherein, (1) infrared emission tube, (2) first groups of " at a high speed " keys, (3) first groups of " low speed " keys, (4) first groups of stop keys, (5) second groups of " at a high speed " keys, (6) second groups of " low speed " keys, (7) second groups of " stopping " keys, (8) on and off switch, (9) infrared receiver tube, (10) first groups of limiting alarms are indicated at a high speed for (11) first groups, (12) first groups of low speed indications, be scheduled to into (14) second groups of limiting alarms of dose indication for (13) first groups, indicate at a high speed for (15) second groups, (16) second groups of low speed indications are scheduled to into dose indication for (17) second groups, (18) power supply indication, (19) on and off switch, (20), (21), (22), (23), (24), (25) be six passages, corresponding to six feature operations, (26) or the door, (27) LF multivibrator, (28) carrier frequency oscillation generator, (29) infrared emission circuit, (30) infrared reception and demodulator circuit, (31) shaping circuit, (32) enumerator, (33) sequential control circuit, (34) decoder, (35) and (36) latch.

Below in conjunction with accompanying drawing this device is described further:

Suppose to require first group of syringe tick-over, second group of syringe high speed operation, can press first group of " low speed " key (3) in the emitter, the passage of emitter (21) produces a waveform, warp or door (26) make LF multivibrator (27) produce 10 milliseconds of two pulsewidths, 100 milliseconds pulse at interval, carrier frequency oscillation generator (28) is delivered in this pulse, its frequency of oscillation is 38 kilo hertzs, control its vibration, the low frequency pulse signal that LF multivibrator (27) is produced is modulated on 38 kilo hertzs of CF signals, is launched by infrared emission circuit (29) again.

The infrared receiver tube of receptor (9), the modulated infrared signal that receives is delivered to infrared reception and demodulator circuit (30) to carry out demodulation and amplifies, deliver to enumerator (32) through shaping circuit (31), signal after the shaping is two electric pulses of 100 milliseconds of being separated by, and its first pulse is the h shown in Fig. 6.Reshaping signal after shaping circuit (31) shaping is delivered to sequential control circuit (33) simultaneously, and by the open pulse of the rising edge triggering for generating enumerator of Fig. 6 h, i as shown in Figure 6 starts working enumerator.Because pulse its width after reception, shaping is far longer than the response time of sequential control circuit, so circuit delay can not exert an influence to count results greater than 10 milliseconds of original emission.Count results is delivered to decoder (34) again and is deciphered, count results is delivered to sequential control circuit (33) simultaneously, make by the open pulse j of i trailing edge triggering for generating latch shown in Figure 6, deliver to latch (35) (with first group inject corresponding latch), and latch (36) is failure to actuate.Latch and make enumerator (32) zero clearing by signal k after finishing, at this moment generator just can send second group " at a high speed " and ordered.Different with the front work process is, count results is failure to actuate latch (35), and decode results is sent to latch (36), makes second group of syringe make propelled at high velocity.

This device can independently be controlled low speed, the high speed of two groups of syringes and stop six kinds of kinestates, and it is carried out by three 538 pairs monostable chips, and six the tunnel monostablely correspond respectively to six passages, have different time constants.If make first group of syringe with " at a high speed " operation, press first group of " at a high speed " key (2), connect 538 k ₁So it is 50 milliseconds pulse that 538 the 10th foot is exported a width, via 4002 or door take on or door (26) deliver to the LF multivibrator of forming by NAND gate 4011 and two monostable triggers 538 (27), produce the pulse of 10 milliseconds of pulsewidths, deliver to the carrier frequency oscillation generator of taking on by two NAND gate 4011 (28) then, make it in 10 milliseconds burst length, to produce 38 kilo hertzs oscillator signal, de-energisation infrared emission circuit (29) is so just there is one group of 38 kilo hertzs of synthetic infrared signal to send by infrared-emitting diode SE303.

The μ PC1373 that the infrared signal that is received by the infrared phototriode 3DU of infrared receiver tube (9) is at first delivered to infrared reception and demodulator circuit (30) goes to export after demodulation, detection, the shaping, six instructions of corresponding emitter, 1373 output 1---6 negative pulses that number does not wait.The pulse of μ PC1373 output is given the enumerator of being made up of 74LS393 (32) on the one hand after 4009 of shaping circuit (31) carries out level conversion, give sequential control circuit (33) on the other hand.The signal of enumerator (32) output is delivered to by 74LS138 and is formed decoder (34), different pulse numbers is just represented in the output of decoder (34), it also is different instructions, its output divides two groups, pulse number 1-3's is first group, and pulse number 4-6's is second group, delivers to latch (35) and (36) of being taken on by two 74LS75 respectively, the corresponding relays drive circuit is delivered in its output, the motion of drive motors pushing syringe.
