Description

Technical Field

[0001] The invention belongs to the technical field of cleaning, and in particular relates to a cardiology treatment catheter cleaning device. Background Art

[0002] Cardiology, also known as cardiovascular medicine, is a clinical department set up by the general internal medicine department of hospitals at all levels to diagnose and treat cardiovascular diseases. There are many treatments for cardiovascular diseases, and cardiac interventional treatment is one of them.

[0003] Cardiac interventional therapy is a new technology for diagnosing and treating cardiovascular diseases. It does not require open chest surgery. Under the guidance of imaging methods, the catheter is sent to the lesion site by puncturing the surface blood vessels with the help of certain instruments. Heart disease is confirmed and treated through specific cardiac catheter operation techniques. However, these catheters are not disposable devices. After each use, they need to be cleaned and sterilized to facilitate the next use.

[0004] In response to the above technical problems, the applicant has retrieved some prior arts, such as a Chinese patent with patent publication number CN114177478B, which is a catheter cleaning device for cardiology. The catheter is clamped in a curved manner on the outside of the work station slot by two rows of limit columns, and the rotating rod is rotated to drive the catheter to rotate in a circular shape in the cabin, so that the cleaning liquid can continuously pass through the catheter, so that it can be cleaned quickly. It can not only clean multiple catheters at one time, but also has a high cleaning efficiency.

[0005] However, the above patent can only clean the inside of the catheter. Since there are contact points between multiple catheters, the outer surface of the catheter cannot be thoroughly cleaned. Moreover, due to the limitations of the diameter of the rotating rod and the length of the carrier block, it can only clean some shorter catheters. Once the length of the catheter exceeds the length of the carrier block, the end of the catheter will hang down, and the water in the cleaning chamber will not be able to enter the catheter, greatly reducing the cleaning effect. Therefore, the use of the above patent is very limited. Summary of the invention

[0040] like Figure 1-Figure 9As shown, a cardiology treatment catheter cleaning device provided by the present invention comprises an outer tube 2 and a tube cover 19, wherein the tube cover 19 is hinged on the top of the outer tube 2, wherein a mounting tube 6 is arranged inside the outer tube 2, wherein a spiral mounting groove 7 for mounting a catheter 18 is provided on the mounting tube 6, wherein the length of the spiral mounting groove 7 can be designed according to the length of the catheter 18, wherein the width of the spiral mounting groove 7 is greater than the diameter of the catheter 18, wherein a plurality of cleaning seats 9 are slidably connected inside the spiral mounting groove 7, wherein the plurality of cleaning seats 9 are equidistantly distributed along the spiral mounting groove 7, wherein a semicircular groove matching the catheter 18 is provided on the side of the cleaning seat 9, wherein a plurality of scraping strips 91 are arranged inside the semicircular groove of the cleaning seat 9, wherein the cleaning seat 9 is provided with a plurality of scraping strips 91 ... During the movement, the scraper strip 91 can scrape off the stains on the outer surface of the conduit 18. The inner side wall of the spiral mounting groove 7 is provided with a second slide groove 14 adapted to the cleaning seat 9. The bottom of the mounting tube 6 is fixedly connected with a water inlet tray 10. The side of the water inlet tray 10 close to the middle of the mounting tube 6 is connected with a water inlet joint 11. The top of the mounting tube 6 is fixedly connected with a water outlet cover 4. The side of the water outlet cover 4 close to the middle of the mounting tube 6 is connected with a water outlet joint 5. The water outlet cover 4 is provided with a drain hole 15 connected with the inside of the mounting tube 6. When installing the conduit 18, the conduit 18 can be wound in the spiral mounting groove 7, and the two ends of the conduit 18 are respectively sleeved on the water inlet joint 11 and the water outlet joint 5. It also includes:

[0041] A water pump assembly, the water pump assembly is arranged in the outer cylinder 2, the output end of the water pump assembly is connected to the water inlet tray 10, the water pump assembly is used to extract water in the outer cylinder 2 and send it into the water inlet tray 10, and the water in the water inlet tray 10 flows into the conduit 18 from the water inlet joint 11, so as to clean the inner wall of the conduit 18;

[0064] When installing the conduit 18, the installation tube 6 is raised to the top of the outer tube 2 by the telescopic rod 1, the fixing pin 318 is pulled out, the connecting rod 311 is removed, and then one end of the conduit 18 is first inserted into the water inlet joint 11, and then the conduit 18 is wound into the spiral installation groove 7, and finally the other end of the conduit 18 is inserted into the water outlet joint 5, and then the connecting rod 311 is re-inserted into the installation rod 312 and fixed with the fixing pin 318;

[0065] The handle 171 is turned, and the handle 171 drives the active bevel gear 174 to rotate through the rotating rod 173, and the active bevel gear 174 drives all the driven bevel gears 172 to rotate, and the driven bevel gear 172 drives the screw rod 176 to rotate, and the screw 176 drives the slider 315 to move, and the slider 315 drives the installation rod 312 and the connecting rod 311 to move through the tension spring 319, and the installation rod 312 flattens the conduit 18, and finally the installation cylinder 6 is lowered into the outer cylinder 2 through the telescopic rod 1, and then enough cleaning liquid is added into the outer cylinder 2, so that the cleaning liquid covers the water outlet cover 4, and the cylinder cover 19 is covered;

[0066] The submersible pump 13 is started, and the submersible pump 13 extracts the cleaning liquid in the outer tube 2 and delivers it to the inside of the conduit 18 through the water inlet joint 11. The cleaning liquid flushes the inside of the conduit 18. When the cleaning liquid in the conduit 18 enters the water outlet cover 4 from the water outlet joint 5, the water flow drives the long water retaining plate 33, the short water retaining plate 32 and the rotating cylinder 31 to rotate. The rotating cylinder 31 drives the rotating disk 314 to rotate. The rotating disk 314 drives the slider 315 and the squeezing cleaning rod 313 to rotate. The squeezing cleaning rod 313 squeezes and cleans the outer side surface of the conduit 18. According to the Bernoulli principle, the squeezing cleaning rod 313 increases the flow rate of the cleaning liquid at the squeezing point of the conduit 18, so that the more stubborn stains in the conduit 18 can be washed away. At the same time, the raised part will also push the cleaning seat 9 to move along the second slide groove 14, and the cleaning seat 9 can clean the side surface of the conduit 18.

[0067] At the same time, the water in the water outlet cover 4 will flow back into the installation tube 6 through the drain hole 15, and the water in the installation tube 6 will be sprayed out from the spray hole 8. Since the spiral installation groove 7 is partially blocked by the conduit 18, the water will be sprayed out from the gap between the spiral installation groove 7 and the conduit 18. The greater pressure will increase the impact force of the cleaning liquid on the side wall of the conduit 18, thereby making the cleaning of the outer side of the conduit 18 quieter.

[0068] The device can also perform multiple water changes to repeatedly clean the conduit 18 to improve the cleaning effect.

[0069] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.

[0070] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
