Description

Technical Field

[0001] The invention relates to the technical field of medical equipment, and in particular to a contrast agent leakage protection device. Background Art

[0002] Doctors usually need to use a variety of examination methods to comprehensively evaluate the patient's cardiovascular condition when diagnosing cardiovascular disease. Commonly used techniques include cardiovascular angiography, computed tomography angiography (CTA) and magnetic resonance angiography (MRA). These technologies can provide detailed cardiovascular images to help doctors accurately evaluate the condition and develop appropriate treatment plans.

[0003] When performing CT angiography (CTA) or magnetic resonance angiography (MRA) examinations, the patient needs to lie on a CT scanning bed or an MRI scanning bed. The doctor will insert a catheter into the patient's elbow or wrist and connect the tube connector of the catheter to the contrast agent input tube connector on the high-pressure injector. Subsequently, the high-pressure injector will inject contrast agent into the patient's body through the contrast agent input tube 02. The inventor found in daily work that there is often residual contrast agent under the headrest of the CT scanning bed or the MRI scanning bed, and even residual contrast agent in the coil 011 inside the device 01. These residual contrast agents will not only corrode the surface of the device, but may also cause corrosion or even short circuit of the electrical components inside the device, causing the device to malfunction. Since the CT or MRI equipment contains complex electronic, mechanical and software systems, the maintenance cost is high, and during the equipment maintenance period, the hospital cannot use the equipment for examination, which seriously affects the quality of medical services and patient satisfaction.

[0004] After investigation, the inventors found that the main reasons for the contrast agent residue on the equipment are as follows: 1) After the patient examination is completed, when the medical staff disconnects the indwelling needle tube connector 04 and the contrast agent input tube connector 03, the residual contrast agent at the connection between the two will drip onto the equipment, causing contrast agent residue; 2) The indwelling needle tube connector 04 and the contrast agent input tube connector 03 are generally threaded connections. The medical staff responsible for the connection sometimes fail to screw the indwelling needle tube connector 04 and the contrast agent input tube connector 03 into place due to busy work, resulting in a loose connection, or because the indwelling needle tube connector 04 and the contrast agent input tube connector 03 themselves have quality problems, resulting in a loose connection between the two. Under the pressure of the high-pressure syringe, the loosely connected indwelling needle tube connector and the contrast agent input tube connector may break apart, causing contrast agent to leak onto the equipment; 3) The film of the indwelling needle injection site 05 is not firmly adhered, or because the patient's vascular conditions are poor, the indwelling needle is inserted shallowly, resulting in the indwelling needle coming out of the blood vessel when injecting the contrast agent, causing contrast agent leakage.

[0005] Therefore, it is necessary to provide a device that can collect contrast media leaked from the injection site of the indwelling needle and the connection between the indwelling needle tube connector and the contrast media input tube connector to prevent the contrast media from flowing onto the equipment. Summary of the invention

[0006] Therefore, the technical problem to be solved by the present invention is to overcome the technical defects in the prior art that the indwelling needle tube connector and the contrast agent input tube connector are manually disconnected after the examination is completed, or are broken by the high pressure of the contrast agent due to loose connection, or the indwelling needle is accidentally removed from the blood vessel when injecting the contrast agent, which will cause the contrast agent to leak onto the equipment, causing corrosion or even short circuit of the internal electrical components of the equipment, leading to equipment failure, thereby bringing huge economic losses. At the same time, the quality of medical services and patient satisfaction will be affected due to the inability to use the equipment. Therefore, a contrast agent leakage protection device is provided, which can collect the contrast agent leaked from the injection site of the indwelling needle and the connection between the indwelling needle tube connector and the contrast agent input tube connector to prevent the contrast agent from flowing onto the equipment.

[0063] In this embodiment, the absorbent pad 14 can be made of a material that is easy to absorb liquid, such as sponge or cotton cloth. The absorbent pad 14 can absorb the contrast agent between the two sets of sealing structures 4 to prevent trace amounts of contrast agent from remaining here and dripping onto the inspection equipment when the first bag body 11 and the second bag body 12 are separated.

[0064] The contrast agent leakage protection device of this embodiment is as follows: Figure 4 As shown, it also includes two sealing plugs 3, which are truncated cone-shaped and have a through hole in the middle suitable for the contrast agent input tube and / or the indwelling needle to pass through; the outer diameter of the small end of the sealing plug 3 is smaller than the inner diameter of the bag mouth 2, and the outer diameter of the large end is larger than the inner diameter of the bag mouth 2; the sealing plug 3 is composed of two symmetrical half sealing plugs 31.

If the outer diameters of the contrast agent inlet tube and the indwelling needle tube are different, sealing plugs 3 with different through hole diameters can be respectively configured, so that both bag mouths 2 can be effectively sealed.
