Description

Technical Field

[0001] The utility model relates to an auxiliary collection device for embolic microspheres, belonging to the technical field of medical equipment. Background Art

[0002] Embolic microspheres are tiny spherical particles mostly made of polyvinyl alcohol. During interventional treatment, embolic microspheres are delivered to the target blood vessels through a catheter, blocking the blood vessels and blood flow, thereby achieving a variety of therapeutic purposes.

[0003] During the production of embolic microspheres, after the reactor is finished, the microspheres are first collected in a sieve frame. The filtrate (e.g., dye solution) is then filtered clean. The microspheres adhering to the sieve frame are then flushed with saline solution and poured into a container for storage. The saline solution flushes away any microspheres adhering to the sieve frame, which would otherwise remain trapped.

[0004] However, the process of flushing the sieve frame to pour the embolic microspheres places high demands on the operator. The operator needs to be able to flexibly adjust the angle and force while slowly pouring the saline solution, while closely observing the state of the embolic microspheres on the sieve frame and the collection container below. During the pouring process, the operator must carefully control the tilt angle and pouring speed of the sieve frame to ensure that the embolic microspheres enter the container smoothly without splashing or other unexpected situations. Therefore, the existing technology often relies on two people to operate, that is, one person holds the sieve frame and adjusts the pouring angle of the sieve frame, while the other person controls the spray system to flush the sieve frame. This is not only time-consuming and labor-intensive, but also difficult to collect and process the saline solution after flushing. Summary of the Invention

[0005] The technical problem to be solved by the utility model is to provide an auxiliary collection device for embolic microspheres which can simplify the operation process and improve the efficiency of single-person operation.

[0006] In order to solve the above technical problems, the utility model proposes an auxiliary collection device for embolic microspheres, comprising a hollow cabinet with an opening at the top, a bracket fixedly mounted on the cabinet, a fixed frame located directly above the cabinet opening and used for detachably mounting a screen frame, the fixed frame being movably mounted on the bracket, the fixed frame being provided with a plurality of first water filter holes, the cabinet being provided with a spray head with an adjustable angle, the spray head being located above the fixed frame; a funnel being provided on the outside of the cabinet, the inlet end of the funnel being provided with a guide groove extending to the bottom of the fixed frame, and a container being provided below the outlet end of the funnel.

[0007] This utility model utilizes an adjustable fixed frame (for mounting the sieve frame) and an automatically spraying spray head, enabling a single operator to easily collect embolic microspheres. This solves the existing problem of requiring one person to tilt the sieve frame and another to flush the collected microspheres, thereby reducing the number of personnel required and improving collection efficiency. During use, the hollow cabinet beneath the sieve frame collects saline solution that falls during flushing, preventing saline from splashing and contaminating the clean environment, thereby improving the cleanliness of polyvinyl alcohol microsphere production.

[0012] This embodiment shows an auxiliary collection device for embolic microspheres, such as Figure 1 As shown, it includes a hollow cabinet 1 with an opening at the top, a bracket 3 fixedly mounted on the cabinet 1, and a fixing frame 4 located just above the opening of the cabinet 1 and used for detachably mounting the screen frame 2. The fixing frame 4 matches the shape of the screen frame 2. Figure 1 The middle screen frame 2 is square, and the fixed frame 4 is as shown in FIG. Figure 1 The shown one is also square; when the screen frame 2 adopts Figure 2 When the circular structure is shown, correspondingly, the fixing frame 4 for fixing the screen frame 2 is also designed to be a matching circular structure. However, the size of the screen frame 2 and the shape, number and size of the sieve holes on the screen frame 2 are not limited, and can meet the operation needs of microspheres of different specifications.

[0013] Preferably, an elastic interlayer 9 is designed on the inner wall of the fixed frame 4 to fix the screen frame 2. The screen frame 2 can be manually clipped into the fixed frame 4 or pulled out of the fixed frame 4, so that the screen frame 2 is detachable. Of course, elastic protrusions can also be provided on the inner wall of the fixed frame 4 to fix and limit the screen frame 2, so that the screen frame 2 can be detachable.

[0014] The fixed frame 4 is movably mounted on the bracket 3. Preferably, the fixed frame 4 is pivotally connected to the bracket 3. In this case, the fixed frame 4 can be fixed at a preset angle using various existing technologies. For example, a protrusion and a groove are provided on the fixed frame 4 and the bracket 3, respectively. When the fixed frame 4 is rotated to a suitable position, the protrusion is embedded in the groove, and the shape of the groove is used to restrict the movement of the protrusion, thereby fixing the angle of the fixed frame 4. In this embodiment, a four-bar linkage driven by an electric telescopic rod is preferably used to adjust the tilt angle of the fixed frame 4, thereby achieving automatic adjustment of the angular tilt of the fixed frame 4. The four-bar linkage is an existing technology and will not be described in detail.

[0015] The fixed frame 4 is provided with a plurality of first water filter holes 12. The cabinet 1 is provided with an adjustable angle spray head 11, located above the fixed frame 4. A funnel 5 is provided on the outside of the cabinet 1. The inlet end of the funnel 5 is provided with a diversion groove 8 extending to the bottom of the fixed frame 4. A container (replaceable container, not shown) is located below the outlet end of the funnel 5. The spray head 11 can be connected to an external saline tank. Preferably, the spray head 11 is connected to the interior of the cabinet 1 via a circulation pump (located inside the cabinet, not shown) and a conduit 6. When the spray head 11 sprays the embolic microspheres on the sieve frame 2, most of the saline flows into the cabinet 1 through the sieve holes in the sieve frame 2 and the first water filter holes 12 in the fixed frame 4, completing the saline recovery and recycling. A small amount of saline flows into the container along with the microspheres. To ensure that the cabinet 1 can better collect the saline, the opening area at the top of the cabinet 1 is at least twice the area of ​​the sieve frame 2.

[0016] Preferably, a drain port is provided at the bottom of the cabinet 1, so that the saline solution in the cabinet 1 can be drained out when necessary to be replaced with new saline solution.

[0017] Preferably, a plurality of second water filtering holes 10 for introducing part of the brine on the diversion trough 8 into the cabinet 1 are provided on the bottom plate of the diversion trough 8 .

[0018] When using this embodiment, the sieve frame 2 is installed in the fixed frame 4, the angle of the fixed frame 4 is adjusted, physiological saline is pre-placed in the cabinet 1, and the microspheres in the sieve frame 2 are sprayed and flushed through the circulation pump, the catheter 6 and the spray head 11. The angle of the spray head 11 can be adjusted, so that a single person can easily operate to collect the microspheres, which solves the problem in the prior art that the microsphere collection requires one person to tilt the sieve frame 2 and one person to flush and collect the polyvinyl alcohol microspheres, reduces the use of personnel, and improves the collection efficiency of the microspheres.

[0019] In this embodiment, the cabinet 1 below the screen frame 2 is hollow, which can collect the physiological saline dropped during the flushing process, prevent the saline from splashing and polluting the clean environment, and improve the cleanliness of the production of polyvinyl alcohol microspheres.
