Description

Technical Field

[0001] This utility model relates to the field of medical device cleaning technology, and in particular to a device for removing foreign objects from the inside of a pre-filled catheter flushing device. Background Technology

[0002] Pre-filled catheter flushing devices inject fluid into blood vessels. Before filling, it is necessary to remove particulate matter, tiny fibers, and other foreign objects from the canister to avoid cross-infection and ensure safety for subsequent use. Traditional cleaning methods often involve ultrasonic cleaning or mechanical flushing combined with manual wiping. However, existing technologies generally suffer from the following problems:

[0003] 1. It has many blind spots for cleaning, is cumbersome to operate, and is difficult to penetrate the narrow cylindrical structure;

[0004] 2. Static electricity easily accumulates on the inner wall of the flushing device. Traditional liquid flushing cannot neutralize the charge, causing tiny particles to continuously adhere to the inner wall, resulting in incomplete cleaning.

[0005] 3. Traditional cleaning devices have a fixed structure and cannot be adapted to pre-filled tubing flushers of different specifications, requiring frequent replacement of parts and increasing maintenance costs. Utility Model Content

[0006] To address the aforementioned technical problems, this invention provides a device for removing foreign matter from the interior of a pre-filled duct flushing device. A unipolar ionizing airflow is blown into the inlet, causing both the interior of the flushing device and its impurities to acquire the same charge, resulting in mutual repulsion and suspension of the impurities. Combined with vacuum suction, this achieves efficient removal of foreign matter from the flushing device. The blow needle adapts to cylinders of different lengths via axial sliding. During movement, it releases ionizing air through multi-directional blowing holes, causing foreign particles to become charged and suspended. Simultaneously, a vacuum pump is activated to extract the suspended matter through the exhaust port. The sealing device employs at least two interlocking sleeves with varying diameters, flexibly adapting to cylinders of different diameters to ensure airtightness. This significantly improves the efficiency of foreign matter removal and solves the problems of high residue rates and poor adaptability associated with traditional cleaning methods.

[0007] To achieve the above objectives, the technical solution of this utility model is to design a device for removing foreign objects from the inside of a pre-filled duct flushing device, including a main body and a blow needle disposed on the main body. One end of the blow needle is an air inlet connected to an air inlet pipe, which is connected to an external ion fan. The other end of the blow needle extends into the inside of the flushing device cylinder. The blow needle is provided with an air blowing hole. The device also includes a sealing device at the connection between the main body and the flushing device cylinder, as well as an exhaust port.

[0008] Preferably, the air holes are distributed along the axial direction of the blow needle.

[0009] Preferably, the blow needle is axially mounted on the body and slides up and down along the body, with the air blowing hole located at the end away from the air inlet. The blow needle's sliding motion along the body allows for simultaneous moving and blowing, improving blowing efficiency.

[0010] Optionally, the vent is located at the end of the flusher cylinder.

[0011] Furthermore, it also includes exhaust ports located on the main body.

[0012] Preferably, a vacuum pump is connected to the outside of the exhaust port. The vacuum pump can accelerate the discharge of suspended air inside the flushing device cylinder, thereby carrying away suspended impurities in a timely manner.

[0013] Preferably, a check valve is provided at the exhaust port. The check valve can prevent airflow backflow and secondary pollution when the ion fan stops working.

[0014] Optionally, the sealing device is a rubber ring.

[0015] Preferably, the sealing device consists of at least two nested bushings. The nested bushings allow for cleaning of pre-filled catheter flushers of different diameters.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. The blow needle is axially mounted on the main body and slides up and down along the main body, which can be adapted to pre-filled catheter flushers of different lengths and can penetrate deep into the narrow cylindrical structure for more thorough cleaning;

[0018] 2. The air inlet is connected to an external ion fan. The air blowing hole releases ion air, which causes foreign particles to become charged and suspended, and then discharged through the exhaust port. Tiny particles cannot adhere to the inner wall, resulting in a more thorough cleaning.

[0019] 3. The sleeves are interlocked, which can clean pre-filled catheter flushers of different diameters. They are easy to replace and have a low cost. Attached Figure Description

[0025] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0026] like Figure 1 As shown, this utility model is a device for removing foreign objects from the inside of a pre-filled duct flushing device. It includes a body 1 and a blow needle 2 disposed on the body 1. One end of the blow needle 2 is an air inlet 21 connected to an air inlet pipe. The air inlet 21 is connected to an external ion fan. The other end of the blow needle 2 extends into the inside of the flushing device cylinder 3. The blow needle 2 is provided with an air blowing hole 22. It also includes a sealing device 4 at the connection between the body 1 and the flushing device cylinder 3, and an exhaust port 5.

[0027] The exhaust port 5 is located at the end 31 of the flushing cylinder.

[0028] A vacuum pump is externally connected to the exhaust port 5.

[0029] The working principle is as follows: The main body 1 is installed inside the flushing cylinder 3. The sealing device 4 can effectively seal the two. The air inlet 21 is connected to the external ion fan. The ion air enters the blow needle 2 through the air inlet 21 and is blown into the flushing cylinder 3 through the blow hole 22 on the blow needle 2. The ion air causes the impurities inside the flushing cylinder 3 to carry ions of the same polarity as the flushing cylinder 3, thereby generating suspension, and is discharged through the exhaust port 5 at the end 31 of the flushing cylinder.

[0030] like Figure 2 , 3 As shown, the air holes 22 are distributed along the axial direction of the blow needle 2. The axially distributed air holes 22 can better blow away impurities inside the flushing cylinder 3.

[0031] like Figure 2As shown, the blow needle 2 is axially mounted on the body 1 and slides up and down along the body 1. The air blowing hole 22 is located at the end away from the air inlet 21. The working principle is as follows: The body 1 is mounted inside the flushing cylinder 3, and the sealing device 4 can effectively seal the two. The air inlet 21 is connected to an external ion fan. The ion air enters the blow needle 2 through the air inlet 21 and is blown into the flushing cylinder 3 through the air blowing hole 22 on the blow needle 2. The ion air causes the impurities inside the flushing cylinder 3 to simultaneously carry ions of the same polarity as the flushing cylinder 3, thereby generating suspension, and is discharged through the exhaust port 5 at the end 31 of the flushing cylinder. In the entire dust removal process, the blow needle 2 slides up and down along the body 1, gradually blowing from top to bottom, which can further improve the blowing efficiency and make the dust removal effect more obvious.

[0032] like Figure 2 As shown, it also includes an exhaust port 5 located on the main body 1. In this embodiment, there are two exhaust ports 5, located on the main body 1 and the end 31 of the flushing cylinder, respectively. The specific working principle is the same as the previous embodiment, except that there are two exhaust ports 5, and both exhaust ports 5 are connected to the vacuum pump, thereby improving the exhaust efficiency and preventing impurities from remaining on the end 31 of the flushing cylinder.

[0033] like Figure 2 , 4 As shown, a check valve 6 is installed at the exhaust port 5. During normal operation, the impurities already suspended inside the flushing cylinder 3 are discharged through the check valve 6 at the exhaust port 5. When the dust removal work is completed and the ion fan stops working, the check valve 6 can prevent external air from flowing back through the exhaust port 5 and causing secondary pollution.

[0034] like Figure 1 As shown, the sealing device 4 is a rubber ring. The rubber ring serves to seal the flushing device cylinder 3, preventing external air from entering the flushing device cylinder 3.

[0035] like Figure 2 , 4 As shown, the sealing device 4 consists of at least two nested sleeves 41. In use, different numbers of sleeves 41 are used to fit different diameter flushing device cylinders 3.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
