Abstract
Description
Technical Field
[0001] The invention relates to the technical field of medical auxiliary equipment, in particular to a urine sampling device. Background Art
[0002] In clinical medicine, urine testing is a widely used test item because it can detect the manifestations of many diseases. In the prior art, before the urine test, the patient needs to hold a urine sample cup in his hand, then urinate at the urine sample cup in the bathroom, and then take the urine sample cup containing the urine sample to the urine test window of the hospital. The above-mentioned urine sample collection mode still has many problems in actual operation, which are specifically reflected as follows. First, since the patient holds the urine sample cup for sampling, it is very likely that urine will be spilled on the hand, which brings inconvenience to the patient and is unhygienic. Second, some patients may load a large amount of urine sample and send it to the urine test window because they are not clear about the amount of urine required for medical tests. In this way, because the amount of urine is too much, it is easy to cause urine to spill during the inspection process (which will also have an adverse effect on the doctor's inspection), which also brings inconvenience to the patient and there is an unhygienic problem. In summary, it is particularly necessary to provide a device that can facilitate patients to take urine samples and can achieve safety and hygiene. Summary of the invention
[0003] In order to overcome the disadvantages of the existing urine sample collection, which brings inconvenience and unsanitary conditions to patients due to the lack of suitable equipment, the present invention provides a urine sample sampling device which is mainly used for male urine sampling. Under the joint action of relevant mechanisms and circuits, when sampling, the patient does not need to hold the urine sample cup with his hands to collect the sample, thus preventing urine from spilling on his hands as much as possible. The device can automatically remind the patient when the urine volume is sufficient, thus reducing the probability of urine spilling out of the urine sample cup later, bringing convenience to the patient. The device can also automatically flush after the sampling is completed, thus ensuring a clean and hygienic urine sample sampling device on site.
[0004] The technical solution adopted by the present invention to solve its technical problem is:
[0005] A urine sample sampling device comprises a urine sample cup body, a solenoid valve, a power module, a gravity sensor, a photoelectric switch, and a fixed cylinder, characterized in that it also has an alarm circuit and a trigger circuit; a partition is arranged in the fixed cylinder, a waterproof gravity sensor and a photoelectric switch are respectively mounted on the partition, a plurality of openings are arranged around the partition, and a drainage hole is arranged at the lower end of the fixed cylinder; a connecting rod is installed at the rear side end of the fixed cylinder, a component box is installed at the upper end of the connecting rod, the solenoid valve is installed at the outside of the component box, the liquid inlet end of the solenoid valve is connected to the tap water pipe, and a flushing pipe is installed at the liquid outlet end of the solenoid valve; the power module, the alarm circuit and the trigger circuit are installed in the component box; the component box is installed on the upper part of the urinal in the bathroom; the signal output end of the photoelectric switch is electrically connected to the signal input end of the trigger circuit, and the power output end of the trigger circuit is electrically connected to the power input end of the solenoid valve.
[0006] Furthermore, the solenoid valve is a normally closed valve core solenoid valve, and the lower end of the flushing tube is vertically located at the upper end of the fixed cylinder.
[0007] Furthermore, the height between the partition of the fixed cylinder and the upper end of the fixed cylinder is lower than the height of the urine sample cup body.
[0008] Furthermore, the photoelectric switch is equipped with a relay, the positive power input terminal of the photoelectric switch is connected to the relay control power input terminal, the positive power output terminal of the photoelectric switch is connected to the relay positive power input terminal, and the negative power input terminal of the photoelectric switch is connected to the relay negative power input terminal.
[0009] Furthermore, the trigger circuit is a time relay module, and the negative power input terminal and the negative trigger signal input terminal of the time relay module are connected.
[0010] Furthermore, the alarm circuit includes an electrically connected adjustable resistor, a resistor, an NPN transistor and a buzzer, one end of the adjustable resistor is connected to one end of the first resistor and one end of the second resistor, the other end of the second resistor is connected to the base of the NPN transistor, the other end of the first resistor is connected to the emitter of the NPN transistor, and the collector of the NPN transistor is connected to the negative power input terminal of the buzzer.
[0011] The beneficial effects of the present invention are as follows: when the patient takes a urine sample, he does not need to hold the urine sample cup with his hands, but can directly place the urine sample cup on the fixed cylinder. The weight of the urine sample cup acts on the gravity sensor. Under the action of the alarm circuit, when the urine sample is sufficient, the patient can be prompted not to urinate in the urine sample cup, thereby preventing too much urine sample from being collected. After the patient takes the urine sample cup, the trigger circuit will control the solenoid valve to open for a period of time to spray water to clean the fixed cylinder. The present invention brings convenience to the patient, and can automatically rinse after the sampling is completed, ensuring the cleanliness and hygiene of the site. In summary, the present invention has good application prospects. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Figure 1 , 2As shown, the solenoid valve DC is a normally closed valve core solenoid valve, and the lower end of the flushing tube 6 is vertically located in the middle of the upper end of the fixed cylinder 2. The height between the partition 21 of the fixed cylinder 2 and the upper end of the fixed cylinder is lower than the height of the urine sample cup body 1. The photoelectric switch A2 is equipped with a relay K1, and the positive power input terminal 1 of the photoelectric switch A2 is connected to the control power input terminal of the relay K1, the positive power output terminal 3 of the photoelectric switch A2 is connected to the positive power input terminal of the relay K1, and the negative power input terminal 2 of the photoelectric switch A2 is connected to the negative power input terminal of the relay K1. The trigger circuit is a time relay module A4, and the negative power input terminal 2 of the time relay module A4 is connected to the negative trigger signal input terminal 4. The alarm circuit includes an adjustable resistor RP1, resistors R1 and R2, an NPN transistor Q1 and a buzzer B connected via circuit board wiring. One end of the adjustable resistor RP1 is connected to one end of the first resistor R1 and one end of the second resistor R2. The other end of the second resistor R2 is connected to the base of the NPN transistor Q1. The other end of the first resistor R1 is connected to the emitter of the NPN transistor Q1. The collector of the NPN transistor Q1 is connected to the negative power input end of the buzzer B. The power input terminals 1 and 2 of the power module A1 are connected to the two poles of the AC 220V power supply via wires, respectively; the power output terminals 3 and 4 of the power module A1 are connected to the power input terminals 1 and 2 of the gravity sensor A5, the power input terminals 1 and 2 of the photoelectric switch A2, the power input terminal of the alarm circuit, the positive power input terminal of the buzzer B, and the emitter of the NPN transistor Q1, and the power input terminal 1 and 2 of the time relay module A4 of the trigger circuit are connected via wires; the signal output terminal relay K1 normally closed contact terminal of the photoelectric switch A2 and the signal input terminal 3 of the time relay module A4 of the trigger circuit are connected via wires, and the power output terminal 9 and 4 of the time relay module A4 of the trigger circuit and the power input terminals of the electromagnetic valve DC are connected via wires.
[0017] Figure 1 , 2As shown, after the 220V AC power enters the power input end of the power module A1, the 3rd and 4th pins of the power module A1 will output a stable DC 12V power supply to the power input end of the photoelectric switch A2 and the gravity sensor A5, the alarm circuit, and the trigger circuit, and the above circuits and sensors are powered on. When a patient collects urine samples, the urine sample cup body 1 is placed in the fixed cylinder 2. The weight of the urine sample cup body 1 acts on the force-bearing surface of the gravity sensor A5 and blocks the transmitting and receiving head of the photoelectric switch A2. The 3rd pin of the photoelectric switch A2 outputs a voltage signal to the positive power input end of the relay K1. The relay K1 is energized to close its control power input end and the normally closed contact end is open, so the 3rd pin of the time relay module A4 will not input a high-level signal. When the patient urinates at the urine sample cup, the urine enters the urine cup body. The more urine there is in the urine cup body 1, the greater the weight acting on the force-bearing surface of the gravity sensor A5, and vice versa. When the amount of urine in the urine cup body 1 is insufficient, the weight acting on the force-bearing surface of the gravity sensor A5 is relatively small. In this way, the voltage signal output from the 3rd pin of the gravity sensor A5 is divided by the adjustable resistor RP1 and the resistor R1, and the resistor R2 steps down the voltage and limits the current, and the base voltage of the NPN transistor Q1 is relatively low (lower than 0.7V). The NPN transistor Q1 will not be turned on, and the buzzer B will not be powered on and make a sound. When the urine volume in the urine cup body 1 is sufficient, the weight acting on the force-bearing surface of the gravity sensor A5 is relatively large. In this way, the voltage signal output by the 3rd pin of the gravity sensor A5 is divided by the adjustable resistor RP1 and the resistor R1, and the resistor R2 steps down and limits the current. The base voltage of the NPN transistor Q1 is relatively high (higher than 0.7V). The NPN transistor Q1 will conduct the collector and output a low level to the negative power input terminal of the buzzer B. The buzzer B will be powered and sound to remind the patient that the urine volume is sufficient and there is no need to urinate in the urine cup body 1 (into the urinal). In this way, the patient can be prevented from pouring too much urine into the urine cup body. After the patient urinates, the urine cup body can be taken out and sent to the hospital laboratory for examination.
[0018] Figure 1 , 2 As shown, after the patient has finished collecting urine samples and removed the urine sample cup body, since there is no object blocking the detection head of the photoelectric switch A2 at this moment, its 3rd pin no longer outputs a low level, and the relay K1 loses power, and its control power input terminal and the normally closed contact terminal are closed. In this way, the 3rd pin of the time relay module A4 will be input with a high level signal, and the 9th pin of the time relay module A4 will output 5 seconds of power to the power input terminal of the solenoid valve DC at intervals of 4 seconds. The solenoid valve DC is powered on and the valve core is opened, so that tap water will flow out from the flushing pipe 6 to flush the inside and outside of the fixed cylinder, ensuring that the fixed cylinder is in a clean state. After 5 seconds, the solenoid valve DC is closed and water no longer flows out, preparing for the next patient to take samples.
[0019] Figure 1 , 2As described above, through the combined action of the above circuits and mechanisms, when the patient takes a urine sample, the patient does not need to hold the urine sample cup with his hands, but can directly place the urine sample cup on the fixed cylinder. The weight of the urine sample cup acts on the gravity sensor. Under the action of the alarm circuit, the patient can be prompted not to urinate in the urine sample cup after the urine sample is sufficient, thereby preventing too much urine sample from being collected. After the patient takes the urine sample cup, the trigger circuit will control the solenoid valve to open for a period of time to spray water to clean the fixed cylinder. The present invention brings convenience to the patient, and can automatically rinse after the sampling is completed, ensuring a clean and hygienic site. Figure 2As shown, power module A1 is a finished product of an AC 220V to 12V DC switching power module of model 220V / 12V / 1KW, with a power of 200W. The model of NPN transistor Q1 is 9013; the resistance values of resistors R1 and R2 are 10.6K and 47K respectively; buzzer B is a finished product of an active continuous sound buzzer alarm of model MF12V; the specification of adjustable resistor RP1 is 470K (adjusted to 60.3K in this embodiment). In actual applications, the larger the resistance value of the adjustable resistor RP1 is adjusted, the greater its partial pressure is. In actual applications, the more urine volume is relatively, the higher the voltage signal output by the gravity sensor A5 is, the NPN transistor Q1 will be turned on, that is, the urine volume threshold of the present invention becomes larger; the smaller the resistance value of the adjustable resistor RP1 is adjusted, the smaller its partial pressure is. In actual applications, the smaller the urine volume is relatively, the higher the voltage signal output by the gravity sensor A5 is, the NPN transistor Q1 will be turned on, that is, the urine volume threshold of the present invention becomes larger; the smaller the resistance value of the adjustable resistor RP1 is adjusted, the smaller its partial pressure is, so in actual applications, the smaller the urine volume is relatively, the smaller the gravity sensor A is, the higher the urine volume is ... urine volume is, the higher the urine volume is, the higher the urine volume is, the higher the urine volume is, the higher the urine volume is, the higher the urine volume is, the higher the urine volume is, the higher the urine volume is, the higher the urine volume is, the higher the urine volume is, the higher the urine volume is, The lower the output voltage signal of 5, the more the NPN transistor Q1 will be turned on, that is, the urine volume threshold of the present invention becomes smaller; the gravity sensor A5 is a finished force sensor of model HZC-30B, which has three terminals, two of which are connected to the power supply, and one is a signal output terminal. When working, the signal output terminal will output an analog voltage signal of 0-12V that changes dynamically with the detected weight data; the relay K1 is a DC12V relay; the time relay module A2 is a finished time controller module of model YYC-2S, and the finished time controller module A2 has two power input terminals 1 and 2, two trigger signal input terminals 3 and 4, a setting button 5, and an emergency stop button The positive and negative power input terminals of the time controller module A2 are powered on. After the operator presses the setting button, the time plus button and the time minus button are operated through the digital display of the digital tube. The normally open power output terminal can output positive power in the required time period. After the set time period, the normally open power output terminal stops outputting power. After the time is set and the two trigger signal input terminals are input with a trigger power signal, the time relay module will count the set time. The photoelectric switch A2 is a PNP infrared reflection photoelectric switch product of model E3K100-60. The working voltage is DC 12V, and it has three connecting wires, two of which are pins 1 and 2 for power input, and the other pin 3 for signal output. The upper end of the photoelectric switch has a detection head, and the transmitter of the detection head will emit an infrared beam when working. When the infrared beam emitted by the detection head is blocked by an object within the maximum range of 60 cm and is received by the receiving head parallel to the detection head, the signal output line pin 3 will output a high level. When there is no object blocking it, the signal output line pin 3 will not output a high level. There is an adjustment knob outside the upper front end of the photoelectric switch housing. When the adjustment knob is adjusted to the left, the detection distance of the detection head becomes closer, and when it is adjusted to the right, the detection distance of the detection head becomes farther (adjusted to 5 cm in this embodiment).
