Description

Technical Field

[0001] This utility model relates to the field of high-pressure injector technology, specifically to an automatic drug aspiration liquid level monitoring mechanism for high-pressure injectors. Background Technology

[0002] High-pressure injectors are indispensable key equipment in medical imaging examinations and interventional treatments. They are mainly used to rapidly inject contrast agents, saline, and other liquids into the patient's blood vessels with precise pressure, flow rate, and dosage. By enhancing the image contrast of the target tissue, they assist doctors in clearly observing vascular structures, organ functions, or lesion sites. Their core characteristics are "high pressure" (meeting the needs of rapid injection) and "precise control" (ensuring the accuracy of dosage, speed, and timing). They are widely used in CT, MRI, DSA (digital subtraction angiography), and other examinations and interventional procedures.

[0003] Generally, the start and stop of the aspiration pump is controlled by real-time monitoring of the liquid level in the high-pressure injector to prevent dry aspiration or insufficient aspiration. However, the installation position of the monitoring sensor is fixed and cannot be adapted to containers of different heights and diameters, resulting in blind spots in the liquid level monitoring of the high-pressure injector, which is quite inconvenient.

[0004] In view of this, we propose an automatic drug aspiration level monitoring mechanism for high-pressure injectors. Utility Model Content

[0005] The purpose of this invention is to provide an automatic drug aspiration level monitoring mechanism for high-pressure injectors to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] The high-pressure injector automatic drug aspiration liquid level monitoring mechanism includes a base, a connecting frame fixedly connected to the top surface of the base, a control console rotatably connected to one end of the connecting frame, a high-pressure injector connected to the bottom surface of the control console, a movable bolt rotatably connected to the bottom surface of the high-pressure injector, a movable sleeve threadedly connected to the side wall of the movable bolt, and a support plate fixedly connected to the side wall of the movable sleeve. Two sets of detection devices are provided on one side of the support plate.

[0008] During the use of the high-pressure injector, the movable bolt can be rotated as needed to move the movable sleeve connected to the bolt thread up and down, thereby adjusting the position of the support plate fixedly connected to the side wall of the movable sleeve. This facilitates the liquid level detection work of the detection device on one side of the support plate, avoids detection blind spots, improves detection accuracy, and is simple, convenient, and easy to use.

[0009] Preferably, the detection device includes a movable slide groove formed on the side wall of the support plate, and the inner wall of the movable slide groove is rotatably connected with a bidirectional bolt. The opposite threads of the bidirectional bolt are threaded with adjusting sleeves, and the side wall of the adjusting sleeve is fixedly connected with an ultrasonic detector. A connecting line is connected between the ultrasonic detector and the control console, and one end of the bidirectional bolt extends out of the support plate and is rotatably connected to the support plate.

[0010] The bidirectional bolts can be rotated according to the size of the high-pressure injector, causing the adjusting sleeves connected by the bidirectional bolt threads to move closer or further apart. This allows for adjustment of the position of the ultrasonic detector fixed to the side wall of the adjusting sleeve, making it easy to adapt to high-pressure injectors of different sizes, thus preventing the generation of detection blind zones and improving detection accuracy.

[0011] Preferably, a strip block is fixedly connected to one end of the bidirectional bolts on the outer side of the support plate;

[0012] By setting up a bar block, rotating the bar block can drive the bidirectional bolt to rotate, making it easy to adjust the position of the ultrasonic detector left and right.

[0013] Preferably, a first support rod is fixedly connected to the top surface of the support plate, and a first fixing plate is slidably connected to the side wall of the first support rod, and the first fixing plate is fixedly installed on the side wall of the control console;

[0014] By setting up the first support rod and the first fixed plate in cooperation, the first support rod will provide a certain support force to the support plate, prevent the support plate from shifting, and improve the stability of use.

[0015] Preferably, one end of the movable bolt is fixedly connected to a rotating nut;

[0016] By using a rotating nut, the movable bolt can be rotated simply by turning the nut, thus improving ease of operation.

[0017] Preferably, the side wall of the rotating nut has a strip groove;

[0018] By setting grooves, the roughness of the sidewall of the swivel nut is increased, friction is increased, and the swivel nut is easier to rotate.

[0019] Preferably, a second support block is fixedly connected to the bottom surface of the control console, and one end of the second support block passes through the movable threaded sleeve and is slidably connected to the movable threaded sleeve. A second fixing plate is slidably connected to the side wall of the movable bolt, and the top surface of the second fixing plate is fixedly connected to the bottom end of the second support block.

[0020] By setting up a second support block and a second fixed plate, the second support block provides a certain limiting support, making the movement of the moving screw sleeve more stable.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] 1. This high-pressure injector automatic drug aspiration liquid level monitoring mechanism allows the user to rotate the moving bolt during high-pressure injector use. This causes the moving sleeve connected to the moving bolt to move up and down, thereby adjusting the position of the support plate fixedly connected to the side wall of the moving sleeve. This facilitates liquid level detection by the detection device on one side of the support plate, avoids detection blind spots, improves detection accuracy, and is simple, convenient, and easy to use.

[0023] 2. This automatic drug aspiration level monitoring mechanism for high-pressure injectors can be adjusted by rotating the bidirectional bolts according to the size of the high-pressure injector. This allows the adjusting sleeves connected by the threaded bidirectional bolts to move closer or further apart, thereby adjusting the position of the ultrasonic detector fixedly installed on the side wall of the adjusting sleeve. This facilitates adaptation to high-pressure injectors of different sizes, prevents the generation of detection blind spots, and improves detection accuracy. Attached Figure Description
