[0023] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0024] Please refer to Figures 1 to 3As shown, an embodiment of the present invention provides a pulmonary artery thrombus filtration and collection device, including a collection cylinder 1. The collection cylinder 1 is provided with a filtration mechanism for multi-layer filtration of thrombi, and the filtration mechanism is detachably installed inside the collection cylinder 1.

[0025] In this embodiment, two filter screens 2 are provided, and the two filter screens 2 are distributed from top to bottom in the collection cylinder 1. The filter hole diameter of the upper filter screen 2 is larger than that of the lower filter screen 2. By setting a double layer of filter screens 2 inside the collection cylinder 1, multiple filtrations can be performed according to the size of the thrombus.

[0026] In this embodiment, a silicone ring 3 is fixedly sleeved on the side of the filter screen 2. The silicone ring 3 is in contact with the inner wall of the collection cylinder 1. The silicone ring 3 prevents blood clots from flowing out from the gap between the filter screen 2 and the collection cylinder 1 during filtration.

[0027] In this embodiment, a limiting slider 301 is integrally formed on the side of the silicone ring 3. The inner wall of the collection cylinder 1 is provided with a slide assembly corresponding to the two filter screens 2. The slide assembly includes a vertical slide groove 101 and a horizontal slide groove 102. The vertical slide groove 101 is opened at the upper end of the inner wall of the collection cylinder 1, and the horizontal slide groove 102 is opened at the lower end of the inner wall of the collection cylinder 1. The bottom of the vertical slide groove 101 is connected to the top of one end of the horizontal slide groove 102. The limiting slider 301 can slide into the horizontal slide groove 102 through the vertical slide groove 101.

[0028] The above settings facilitate the installation and removal of the filter screen 2. During installation, align the limiting slider 301 with the vertical slide groove 101, and then press the filter screen 2 down so that the limiting slider 301 slides from the vertical slide groove 101 into the horizontal slide groove 102. Then rotate the filter screen 2 so that the limiting slider 301 is screwed into the end of the horizontal slide groove 102 away from the vertical slide groove 101.

[0029] In this embodiment, a handle 201 is fixedly connected to the top of the filter screen 2 for easy handling.

[0030] In this embodiment, the handle 201 is provided with an anti-slip notch 202. The anti-slip notch 202 is provided to prevent the hand from slipping when holding the handle 201.

[0031] In this embodiment, in order to facilitate the measurement of the amount of blood extracted during the operation, the outer wall of the collection cylinder 1 is provided with a scale 103.

[0032] In this embodiment, an anti-slip pad 104 is fixedly connected to the bottom of the collection cylinder 1. Through the above-mentioned setting, the stability of the collection cylinder 1 when placed on the operating table is guaranteed.

[0033] In this embodiment, the shape of the limiting slider 301 corresponding to each filter screen 2 is different, so as to facilitate the identification of the size of the filter holes on the filter screen 2.

[0034] The foregoing description illustrates and describes several preferred embodiments of the present invention. However, as previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the inventive concept described herein through the foregoing teachings or techniques or knowledge in related fields.
