Description

Technical Field

[0001] The present invention relates to the technical field of medical device disinfection, and more particularly to a cerebrovascular interventional therapy device disinfection apparatus and its usage method. Background Art

[0002] Cerebrovascular intervention is an advanced medical technique. It uses specific medical devices to enter the cerebral artery through the femoral artery of the patient, thereby achieving the purpose of angiography examination of the entire cerebral blood vessels. This examination method can help doctors diagnose and treat cerebrovascular diseases more accurately. However, during the operation, doctors will use a variety of different treatment devices, and these devices must be thoroughly disinfected after use to ensure that there are no residual germs on the surface of the devices. This is to prevent the germs on the device surface from infecting other patients or medical staff. Therefore, it is particularly important to use a dedicated treatment device disinfection apparatus to disinfect these devices. However, there are still some problems with the cerebrovascular interventional therapy device disinfection apparatuses on the current market, and these problems affect the disinfection effect and usage efficiency: (1) First of all, when the current cerebrovascular interventional therapy device disinfection apparatuses on the market perform disinfection, they often cannot ensure that the disinfectant solution evenly covers every corner of the device. This uneven coverage is likely to cause some areas to be missed, so that the treatment devices taken out of the apparatus may still carry germs. In this case, the devices must be redisinfected before they can be used again. This repeated disinfection not only affects the usage experience of the entire disinfection apparatus, but also greatly reduces the efficiency of medical work; (2) Secondly, the existing cerebrovascular interventional therapy device disinfection apparatuses are difficult to accurately control the dosage of the disinfectant solution during the disinfection process. Too much or too little dosage of the disinfectant solution will affect the disinfection effect. In addition, after disinfection, the disinfectant solution cannot be discharged in time, which may not only lead to waste of the disinfectant solution, but also cause secondary contamination due to the retention of the disinfectant solution. This secondary contamination poses a potential threat to the health of medical staff and the safety of subsequent use of the devices.

[0003] The patent with the application number 202123174375.4 discloses a disinfection device for cerebrovascular intervention treatment instruments, including a box body, a box cover and support feet. In the middle of the lower part inside the box body, there is a motor, and above the motor, there is a rotating rod connected by a rotating shaft. Around the rotating rod, there is a supporting net. In the middle position of the rotating rod, there is a bevel gear set. Inside the bevel gear set, there is a rotating shaft, and on both sides of the rotating shaft, there are cams. Through structures such as the rotating rod, the supporting plate, the top teeth, and the cams, in this cerebrovascular intervention treatment instrument disinfection device, when the treatment instrument is placed on the supporting net, the motor is started to drive the rotating rod to rotate, thereby driving the supporting net to rotate. And the rotation of the rotating rod drives the bevel gear set to rotate, causing the rotating shaft to rotate, driving the upper cams to rotate, thereby pushing the supporting plate, making the top teeth above the supporting plate move upward, pushing open the treatment instrument, so that all parts of the treatment instrument can be rinsed by the disinfectant solution, improving the work efficiency of disinfection.

[0004] However, in this patent, there are still problems that the atomization pressure of the nozzle will gradually become insufficient and the spray holes will be blocked as the usage time prolongs. When this situation occurs, the spraying method with a single-side nozzle cooperating with the rotation of the supporting net will result in uneven spraying, thus leading to incomplete disinfection. Moreover, it only has the function of spraying disinfectant solution. After the spraying is completed, the disinfectant solution remains in the pipeline, which is easy to corrode the pipeline. And the device in this patent has a relatively single function and poor applicability. Summary of the Invention

[0005] The purpose of the present invention is to provide a disinfection device for cerebrovascular intervention treatment instruments and its using method, which can achieve more thorough disinfection of cerebrovascular intervention treatment instruments through a more uniform disinfectant solution spraying method and the combined application of disinfectant solution disinfection and pure water rinsing.

[0006] To achieve the above purpose, the present invention provides a disinfection device for cerebrovascular intervention treatment instruments, including a box body, which includes a disinfection part and a water storage part; the disinfection part includes a disinfection rack and a chute for supporting the disinfection rack.
