Description

Intelligent catheterization device

technical field

The invention relates to medical equipment, in particular to an intelligent urinary catheterization device.

Background technique

Patients with spinal cord injuries and some patients with urinary control system diseases have no self-controlled urination function, and the urine accumulated in the bladder cannot be discharged in a timely manner, which will cause kidney damage and endanger life. The method commonly used at present is to indwell a catheter for a long time in patient's bladder to catheterize at any time. This solution solves the problem of catheterization, but since the bladder and sphincter are in a continuous open state, in the long run, the patient's bladder function and sphincter function will fail and atrophy of disuse. In order to solve this problem, a special B-ultrasound (also known as bladder urine volume tester) can be configured for the patient to repeatedly measure the bladder urine volume. When the urine volume exceeds a certain value, the patient can insert a catheter to urinate in time. It can not only timely catheterize but also protect the bladder and sphincter. However, it is not only expensive to use this method to urinate, but it is very inconvenient for patients to repeatedly measure at night.

Chinese patent application number: 2011201712857 discloses a self-control indwelling catheterization device, which is equipped with a solenoid valve and a pressure sensor on the catheter. When the bladder pressure is lower than a certain limit value, the solenoid valve is closed, and the bladder function is protected; when the bladder pressure is greater than a certain limit value, the solenoid valve is opened. However, this device has a fatal flaw. Because not all patients with urinary control system will increase the bladder pressure when the urine in the bladder reaches a certain amount, there are some patients (such as patients with bladder paralysis) when the bladder urine accumulates to the amount of urine that damages the upper urinary tract, the bladder pressure also increases. It will not increase significantly, so there are unsafe factors when using it.

Detailed ways

As shown in Figures 1 and 2, the intelligent urinary catheterization device according to the present invention includes a catheter 1 and a low-voltage DC power supply unit 2; 3. The other two nozzles are respectively connected with the liquid inlet of the hydraulic sensor 4 and the electromagnetic control valve 5 for collecting the internal pressure of the bladder; The signal input end is connected with the control signal output interface of the information processing controller 7 (single-chip microcomputer); The output interface connection is used to process data from the hydraulic sensor 4 and the diet information input board 8, and controls the opening and closing of the electromagnetic control valve 5; the diet information input board 8 is used to store the diet parameters of each meal of the patient.

The working principle of the present invention is briefly described as follows:

1. Control the opening and closing of the electromagnetic control valve 5 by detecting the change of urine pressure in the bladder through the hydraulic sensor 4: this device is equipped with a hydraulic sensor 4 on the urinary catheter 1. According to the principle of the connector, when the hydraulic sensor 4 can receive The data is exactly the numerical value of the urine in the bladder in the patient's body, and this numerical value is transmitted to the information processing controller 7 for data processing. If the pressure of the urine in the bladder in the patient's body exceeds the set threshold, the electromagnetic control valve 5 is opened to drain the urine, and a time delay is performed to complete the patient's urination.

2. Input the dietary parameters of each meal of the patient through the dietary information input board 8, and the information processing controller 7 processes the dietary parameters, and simulates and calculates the relationship between the amount of urine in the patient's bladder and the digestion time. When the pressure transmitted by the hydraulic sensor 4 has not reached the set threshold, the information processing controller 7 sends a control signal to forcibly open the electromagnetic control valve 5 to urinate, so as to ensure that the patient urinates normally.

3. The low-voltage direct-current power supply unit 2 provides low-voltage direct-current power for the device to ensure that electromagnetic interference is minimized.
