Description

Technical Field

[0002] Medical devices refer to instruments, equipment, appliances, in vitro diagnostic reagents and calibrators, materials and other similar or related items that are used directly or indirectly on the human body, including the required computer software. Currently, the use of catheters is usually required for connection in the process of using instruments to provide treatment to patients.

[0003] For example, the Chinese invention provides "a medical instrument auxiliary tool", announcement number: CN116617539A, which includes a positioning device and a correction component. The top of the positioning device is provided with a correction component. The catheter responsible for infusion or drainage is installed at the positioning component, and the catheter is corrected and the direction is determined by following the twisting of the universal bamboo joint and the serpentine tube. The catheter that needs to be turned can be wound and turned on the winding rod at the top of the serpentine tube to change the direction; and the catheter on the rear side can be lifted for auxiliary correction. Medical staff do not need to hold the catheter for a long time. The catheter can be wound in combination with the auxiliary component. For catheters that are too long, they can be folded and bent for correction, shortening the distance between the catheters to prevent the catheters from being too long and causing tripping and medical accidents.

[0004] The catheter correction tool for medical instruments in the above-mentioned technology uses a base plate of neodymium iron boron permanent magnet material to magnetically adsorb and fix the whole body to the medical instrument during use. Due to the action of magnetic force, it often has an adverse effect on the normal operation of the electrical components inside the medical instrument, and in severe cases, it may cause the medical instrument to malfunction and be damaged, thereby affecting the service life of the medical instrument. At the same time, in the process of placing the catheter in the guide groove, although the barrier column can limit the catheter, when the specification of the catheter is close to the inner diameter of the guide groove, it is necessary for personnel to press the catheter with great effort to place it inside the guide groove, which causes great inconvenience to the personnel.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The present invention facilitates uniform accommodation and guidance of multiple groups of catheters through the arrangement of catheter grooves, effectively avoiding the entanglement of the catheters due to crossing and chaotic placement during use, thereby achieving the effect of distributing and correcting the positions of multiple groups of catheters, and through the arrangement of direction adjustment frames and fixing straps, the directions of the catheters can be effectively restrained and corrected during use, further avoiding the entanglement of the catheters due to crossing and chaotic placement during use, and at the same time, through the arrangement of rotating cylinders, adjusting screws, L-shaped moving rods, pistons, adsorption seats, air guide cylinders and fixing seats, the overall and medical The invention can quickly fix the medical instruments, effectively avoid the influence on the working operation of the medical instruments by adsorption and fixation through magnetic force, and bring great convenience to the subsequent disassembly work of the personnel. At the same time, under the cooperation between the piston, the air guide cylinder, the sealing pressure plate, the control valve, the air guide tube, the fixing cylinder and the limiting column, the catheter groove and the catheter can be effectively limited during use, effectively avoiding the catheter from being loosened from the inside of the catheter groove, ensuring the stability of the catheter arrangement and correction, and effectively avoiding the catheter from being subjected to large resistance during the placement process, which brings great convenience to the use of medical personnel.

[0018] 2. The present invention provides a sealing pressure plate, a second spring and an adjusting rod. When a person needs to take out the catheter inside the catheter groove, the sealing pressure plate can be driven to move upward along the surface of the air guide tube and the guide sleeve by pulling the adjusting rod upward. The second spring can be compressed and the air inside the fixed tube can be drawn into the air guide tube through the air guide tube and the control valve during the movement of the sealing pressure plate. During the process of the air inside the fixed tube being drawn out, the limiting column can move along the inner cavity of the fixed tube and shrink to the inside of the fixed tube, so that the limiting column can be detached from the right side of the catheter placed in the catheter groove, thereby releasing the limit of the catheter, so that the person can quickly remove the catheter. The setting of the limiting slide rod achieves the purpose of guiding the adjusting rod and avoids the adjusting rod from tilting during the movement.

[0019] 3. The present invention arranges a torsion spring, a first contact block, a second contact block and an audible and visual alarm. When the catheter is pulled by the patient during use, the pulling force of the patient can drive the direction adjustment frame and the rotating shaft to rotate along the bearing on the rotating support. The rotating shaft rotates to apply pressure to the torsion spring, and at the same time, it can drive the second contact block to rotate, so that the second contact block can contact the surface of the first contact block under the action of rotation, thereby connecting the circuit of the audible and visual alarm, so that the audible and visual alarm can give audible and visual alarm prompts to the surrounding medical staff, so that the medical staff can discover it in time and make corresponding safety measures.

[0020] 4. The present invention can effectively lock and limit the rotating support, the rotating shaft and the direction adjustment frame through the arrangement of the moving plate, the positioning block, the guide vertical rod, the first spring and the adjusting toothed disc, so as to prevent the direction adjustment frame from rotating during use and causing the direction of the catheter to change. When a person needs to adjust and correct the direction of the catheter, the person presses the rotating cylinder to move downward along the surface of the adjusting screw, which can drive the moving plate and the positioning block to move along the surface of the guide vertical rod. When the first spring is compressed, the surface of the positioning block can be separated from the surface of the adjusting toothed disc. Then, the person can manipulate the direction adjustment frame, the rotating shaft and the rotating support to rotate until the direction adjustment frame and the catheter fixed on the surface can be adjusted and corrected to the desired direction. Then, the person stops pushing the rotating cylinder and, under the push of the first spring tension, can push the moving plate and the positioning block to move upward, so that the positioning block can contact the side of the adjusting toothed disc, and can effectively lock and limit the rotating support, the rotating shaft and the direction adjustment frame, so that it is convenient for the person to adjust and correct the direction of the catheter according to needs, which is convenient for the person to use.

[0021] 5. The present invention effectively improves the sealing of the contact between the guide sleeve and the L-shaped movable rod, the piston and the air guide cylinder, and the limit column and the fixed cylinder by arranging the first sealing ring, the second sealing ring and the third sealing ring. The purpose of guiding the adjusting screw and the rotating cylinder is achieved by arranging the guide groove and the guide block, ensuring that the adjusting screw and the rotating cylinder can maintain synchronous rotation. The sealing of the contact between the bottom of the adsorption seat and the medical instrument is effectively improved by arranging the rubber pad. The sub-Velcro and the mother Velcro facilitate personnel to use the fixing strap to bind and fix the catheter and the direction adjustment frame. The driving knob and the anti-slip pattern facilitate personnel to operate the rotating cylinder for rotation. BRIEF DESCRIPTION OF THE DRAWINGS
