When the physiological saline is sprayed on the driving wheel 104 and falls on the auxiliary wheel 102, the physiological saline dilutes blood on the driving wheel 104 and the auxiliary wheel 102, on one hand, friction force between the driving wheel 104 and the auxiliary wheel 102 and the catheter 2 can be increased, so that the catheter 2 can be stably driven when the driving wheel 104 rotates, and on the other hand, the upper cleaning block 408 and the lower cleaning block 410 can be cleaned more easily, and running stability of the catheter 2 is ensured.
The cleaning sponge is also arranged on the connecting rod 409, physiological saline is sprayed into the cleaning sponge on the connecting rod 409 in the falling process, and when the catheter 2 passes through the cleaning sponge on the connecting rod 409, the adhered blood on the catheter 2 is cleaned through the action of the cleaning sponge, so that the stability of friction force of the catheter 2 is ensured when the catheter passes through between the driving wheel 104 and the auxiliary wheel 102, and the stability of equipment use is improved.
According to the invention, by arranging the electromagnet 404, the piston plate 403, the upper cleaning block 408, the torsion spring, the lower cleaning block 410 and other components, when the equipment is in operation, when the rotation speed sensor 103 detects that slippage occurs between the driving wheel 104 and the guide pipe 2, the equipment is electrified to the electromagnet 404, the electromagnet 404 is electrified to lower the piston plate 403 under the action of magnetic force, so that the liquid discharge pipe 412 discharges physiological saline to clean the driving wheel 104, and is influenced by the magnetic force, the upper cleaning block 408 is attached to the driving wheel 104, the lower cleaning block 410 is attached to the auxiliary wheel 102, so that the driving wheel 104 and the auxiliary wheel 102 are cleaned under the cooperation of the physiological saline, the operation stability of the equipment is ensured, and after the equipment is used, the disinfection water is introduced into the liquid storage bin 402, and the corresponding operation equipment is used for disinfecting all components in the housing 101, so that the generation of medical waste is reduced, and the use effect of the equipment is improved.
Example 3
A detection method of a vascular catheter intervention information detection module, which utilizes a vascular catheter intervention information detection module to detect, comprises the following steps:
step one, firstly, the device is wholly placed beside a patient, the device is made to approach to the position of the patient for vascular intervention operation, and the catheter 2 is inserted into the device.
Step two, as the operation proceeds, the drive motor 105 is started, and the catheter 2 is moved with the aid of the drive motor 105, so that the catheter 2 is inserted into the blood vessel to perform a corresponding operation.
Step three, after that, when the catheter 2 is inserted into a blood vessel, the travel distance and the resistance of the catheter 2 are detected by the aid of the rotation speed sensor 103 and the six-dimensional force sensor 14, and the detection result is displayed by the display screen 15.
And fourthly, after the operation is finished, the driving motor 105 is reversed, the catheter 2 is enabled to stably leave the blood vessel, and the device stores detection data in the operation process.
The invention relates to a vascular catheter intervention information detection module and a detection method, wherein the installation mode, the connection mode or the setting mode of the vascular catheter intervention information detection module and the detection method are all common mechanical modes, and can be implemented as long as the beneficial effects of the vascular catheter intervention information detection module and the detection method can be achieved.
