In this regard, the utility model improves the above scheme and provides a urine collector that can adjust the length of the catheter by infrared remote control to reduce the workload of medical staff.

[0038] Definition: When the button K1 is pressed, the electric telescopic rod 9 is controlled to extend, and when the button K2 is pressed, the electric telescopic rod 9 is controlled to shorten. When the button K1 is pressed, the infrared transmitting module 6 sends infrared rays to the infrared receiving module 7. The infrared receiving module 7 generates a feedback signal after receiving the infrared rays, and sends the feedback signal to the first single-chip microcomputer 8. The first single-chip microcomputer 8 decodes the feedback signal according to its built-in computer program, and outputs a high level to the base of the first NPN transistor, and outputs a low level to the second NPN transistor at the same time, so that the first NPN transistor is turned on, the second NPN transistor is not turned on, the coil of the first relay is energized, the normally open end of the first relay is turned on, and the second transistor is not turned on, the coil of the second relay is not energized, and the normally closed end of the second relay is turned on.

The current flows to the negative electrode of the electric telescopic rod 9 through the positive electrode of the power module 10 and the normally open end of the second relay, and then flows from the positive electrode of the electric telescopic rod 9 to the normally closed end of the first relay, and finally flows to the positive electrode of the power module 10, thereby making the electric telescopic rod 9 conduct in the reverse direction. At this time, the electric telescopic rod 9 is shortened.

[0039] A bellows 20 is provided between the urine funnel 5 and the extension tube 4. The bellows 20 is generally a hose, which is convenient for changing the direction of the urine funnel 5 and is more convenient to use.

The function of the one-way valve 51 is to prevent urine reflux and reduce the odor emission in the urinal 2. A funnel cover 52 is provided at the other end of the urine funnel 5. The function of the funnel cover 52 is to further improve the sealing performance. A quick-absorbing sponge layer 53 is provided in the middle of the urine funnel 5. The function of the quick-absorbing sponge layer 53 is to quickly absorb the urine discharged into the urine funnel 5 by the patient, so as to avoid urine splashing when the patient urinates a large amount, which has a certain degree of impact on the surrounding environment.

[0040] In addition, the urine collecting device also includes a third single-chip microcomputer 30, a fan 40 and a fan switch button 50, wherein the fan 40 is arranged on the bottom surface of the funnel cover 52, and the surface of the funnel cover 52 is provided with an air inlet 54 and an air outlet 55, and the fan 40 is used to blow air into the urine collecting funnel 5; the third single-chip microcomputer 30 and the fan switch button 50 are both arranged on the outer surface of the funnel cover 52, and the fan switch button 50 is electrically connected to the input end of the third single-chip microcomputer 30, and the output end of the third single-chip microcomputer 30 is electrically connected to the input end of the fan 40, and the surface of the funnel cover 52 is also provided with a power supply module for providing working voltage to the components.

By pressing the heating switch button 70, the inside of the urine receiving funnel 5 can be preheated, and the air drying of the quick absorbent layer 53 can be accelerated in conjunction with the fan 40. However, it should be noted that the temperature generated by the heating coil 60 should not be too high, so as not to damage the funnel cover 52, the urine receiving funnel 5 and the fan 40.

[0042] When the urine collector of this embodiment is in use, the urinal 2 is placed on the base 1, and the mouth of the urinal 2 is connected to the end of the catheter 3, and the urinal 2 is fixed to the base 1 with a strap 11. Then the base 1 is moved to the side of the bed, and the mouth of the urinal 2 is directed toward the urination site of the patient. Then the medical staff can hold the box body 61 (the patient who can move independently can operate it by himself or by his family members), and by pressing the telescopic button 63, infrared rays are emitted to the infrared receiving module 7. The first single-chip microcomputer 8 controls the extension and contraction of the electric telescopic rod 9 according to the corresponding feedback signal. The extension and contraction of the electric telescopic rod 9 drives the extension tube 4 to move in the catheter 3, thereby achieving the purpose of adjusting the length of the extension tube 4 extending out of the catheter 3, so that the urine collecting funnel 5 can be close to the urination site of the patient. Compared with the prior art, the urine collector can adjust the length of the extension tube 4 by infrared remote control, which is more labor-saving and reduces the workload of medical staff. At the same time, the direction of the urine funnel 5 can be changed by the bellows 20, so that the port of the urine funnel 5 is more convenient to align with the patient's urination part. Patients who can move independently can directly pick up the urine funnel 5 and open the funnel cover 52 to urinate. Patients who cannot move independently can be helped by family members or medical staff to pick up the urine funnel 5. After the patient finishes urinating, cover the funnel cover 52, press the fan switch button 50 and the heating switch button 70, and air-dry the quick-absorbing cotton layer 53 in the urine funnel 5 to reduce bacterial growth. After that, the telescopic button 63 can be pressed again to shorten the electric telescopic rod 9, so that the urine funnel 5 is away from the bed to avoid interfering with the patient's activities or rest. When urinating again, the electric telescopic rod 9 is extended again, which is more practical and meets the needs more strongly. After the urine in the urinal 2 is full, the urinal 2 can be removed, the urine can be poured out and then put back.
