[0032] The preferred embodiments of the present utility model will be specifically described below in conjunction with the accompanying drawings. The accompanying drawings form a part of this application and are used together with the embodiments of the present utility model to explain the principles of the present utility model, rather than to limit the scope of the present utility model.

[0033] A specific embodiment of the present utility model, as Figure 1 shown, discloses an infusion filter fixing device, which includes a pipeline fixing component 1, a filter fixing unit 2, a limiting component 3 and a fixing clip 4. The pipeline fixing component 1 is connected to the filter fixing unit 2. The filter fixing unit 2 is a cavity structure. The limiting component 3 is arranged in the cavity of the filter fixing unit 2. The limiting component 3 is used to fix the position of the infusion filter. The fixing clip 4 is connected to the filter fixing unit 2 and is used to fix the fixing device on the patient's clothing.

[0034] As Figure 1 shown, the number of the pipeline fixing components 1 is two, which are respectively connected to both ends of the filter fixing unit 2. The pipeline fixing component 1 includes a fixing plate 11, a pipeline limiting member 12 and a fixing head 13. The pipeline limiting member 12 is made of an elastic material. The pipeline limiting member 12 and the fixing head 13 are arranged on the fixing plate 11. The fixing head 13 is used to connect the pipeline fixing component 1 with the filter fixing unit 2. The pipeline limiting member 12 is in a circular ring shape and penetrates through the fixing plate 11. The pipeline limiting member 12 is composed of an elastic material and is used to limit the position of the pipeline connected to the infusion filter. Preferably, a buckle is arranged on the pipeline limiting member 12, so as to fix the pipeline more firmly.

[0035] As Figure 2 shown, the fixing head 13 includes a fixing end 131, an insertion end 132 and a spring 133. The fixing end 131 is connected to the insertion end 132. One end of the spring 133 is connected to the fixing end 131, and the other end is connected to the fixing plate 11. The insertion end 132 is set in an arrow shape and penetrates through the fixing plate 11. A positioning block 1321 is arranged on the insertion end 132, and the positioning block 1321 can fix the pipeline fixing component 1 and the filter fixing unit 2.

[0036] As Figure 1As shown, the filter fixing unit 2 includes a first fixing frame 21, a second fixing frame 22, an adjusting assembly 23 and a connection groove 24. The first fixing frame 21 and the second fixing frame 22 are cavity structures. Connection grooves 24 are provided on the first fixing frame 21 and the second fixing frame 22. The number of connection grooves 24 is multiple. The connection grooves 24 cooperate with the insertion end 132 to connect the pipeline fixing assembly 1 with the first fixing frame 21 and the second fixing frame 22. The first fixing frame 21 and the second fixing frame 22 are connected by the adjusting assembly 23. By adjusting the adjusting assembly 23, the length of the filter fixing unit 2 can be changed, so that the filter fixing unit 2 can fix infusion filters of different lengths.

[0037] As Figure 3 shown, positioning holes 241 are provided in the connection groove 24. The positions and shapes of the positioning holes 241 cooperate with the positioning blocks 1321. When the positioning blocks 1321 enter the positioning holes 241, the connection between the pipeline fixing assembly 1 and the filter fixing unit 2 can be fixed. When it is necessary to connect the fixed pipeline fixing assembly 1 and the filter fixing unit 2, insert the insertion end 132 into the connection groove 24 to make the positioning blocks 1321 enter the positioning holes 241. When it is necessary to remove the fixed pipeline assembly 1, press the fixed end 131 to make the positioning blocks 1321 leave the positioning holes 241. The spring 133 is in a compressed state. Stop pressing the fixed end 131, and the spring 133 returns from the compressed state to push the fixed end 131 to move away from the fixing plate 11, thereby driving the insertion end 132 to move, so that the positioning blocks 1321 leave the positions of the positioning holes 241 and remove the fixed pipeline assembly 1.

[0038] As Figures 4 to 5 shown, the adjusting assembly 23 includes a connection frame 231, a pushing and pulling member 232, a buckle 233 and a positioning member 234. One end of the connection frame 231 is connected to the first fixing frame 21, and the other end is connected to the second fixing frame 22. An empty groove is provided on the second fixing frame 22. The connection frame 231 can be received in the empty groove of the second fixing frame 22 and can move along the second fixing frame 22. The pushing and pulling member 232 is arranged on two side surfaces of the first fixing frame 21. Moving the pushing and pulling member 232 can make the connection frame 231 move along the second fixing frame 22. The positioning member 234 is arranged on the second fixing frame 22. The position and shape of the positioning member 234 cooperate with the pushing and pulling member 232. The buckle 233 is connected to the pushing and pulling member 232. When the positioning member 234 contacts the pushing and pulling member 232, flip the buckle 233 to make the buckle 233 buckle on the positioning member 234, and connect the pressing positioning member 234 and the pushing and pulling member 232, so that the connection frame 231 is fixed in the empty groove of the second fixing frame 22 and the first fixing frame 21 is connected to the second fixing frame 22.

[0039] As Figure 6As shown, a sliding groove 221 is provided on the second fixing frame 22, and a bump 2211 is provided on the sliding groove 221. The bump 2211 inclines towards the cavity of the second fixing frame 22 along the direction in which the second fixing frame 22 is connected to the pipeline fixing assembly 1. The positioning member 234 includes a slider 2341, a limiting member 2342, and a moving groove 2343. The slider 2341 is connected to the limiting member 2342, and a moving groove 2343 adapted to the bump 2211 is provided on the slider 2341, so that the slider 2341 can slide in the sliding groove 221 along the bump 2211. When the slider 2341 slides in the direction away from the first fixing frame 21, the limiting member 2342 gradually presses the connecting frame 231 along with the movement of the slider 2341 to fix the displacement of the connecting frame 231.

[0040] When it is necessary to adjust the length of the filter fixing unit 2, remove the buckle 233 from the positioning member 234, move the push-pull member 232 to pull the connecting frame 231 out of the second fixing frame 22, move the connecting frame 231 until the length of the filter fixing unit 2 matches the length of the infusion filter, move the slider 2341 in the direction away from the first fixing frame 21, so that the slider 2341 moves along the bump 2211, thereby enabling the limiting member 2342 to gradually squeeze the connecting frame 231 until the limiting member 2342 clamps the connecting frame 231 to fix the position of the connecting frame 231.

[0041] As Figure 7 shown, the limiting assembly 3 is provided on the inner walls of the first fixing frame 21 and the second fixing frame 22. The limiting assemblies 3 are symmetrically arranged. The limiting assembly 3 includes a limiting block 31 and a compression spring 32. The limiting block 31 is connected to the inner wall of the first fixing frame 21 or the second fixing frame 22 through the compression spring 32. The limiting block 31 is made of a non-slip plastic material. Exemplarily, the limiting block 31 is made of rubber. When the infusion filter is placed, the infusion filter squeezes the compression spring 32 for compression, so that the limiting block 31 clamps the infusion filter to fix the infusion filter in the filter fixing unit 2.

[0042] When it is necessary to fix the infusion filter, unscrew the buckle 233 from the positioning member 234 to release the connection between the first fixing frame 21 and the second fixing frame 22, move the push-pull member 232, move the connecting frame 231 until the length of the filter fixing unit 2 matches the infusion filter, move the slider 2341 in the direction away from the first fixing frame 21 to fix the position of the connecting frame 231 by the limiting member 2342, pass the pipeline of the infusion filter through the pipeline limiting member 12, connect the pipeline fixing assembly 1 and the filter fixing unit 2 according to the above method, enable the limiting assembly 3 to fix the infusion filter in the filter fixing unit 2, and clamp the fixing device on the patient's clothing through the fixing clip 4.

[0043] Compared with the prior art, the infusion filter fixing device of the present utility model can effectively fix the infusion filter and the pipeline connected to the infusion filter by setting the pipeline fixing component 1 and the filter fixing unit 2, preventing the risk of pipeline disconnection and disconnection between the infusion device and the central vein during the use by the patient due to the unfixed position of the filter; the fixing device is fixed on the patient's clothing by setting the fixing clip 4 to reduce the burden of the infusion filter on the patient's neck and effectively fix the infusion filter; the length of the filter fixing unit 2 can be adjusted by setting the adjusting component 23, so that the filter fixing unit 2 can fix infusion filters of different lengths; the filter fixing unit 2 can effectively limit and fix infusion filters of different heights by setting the limiting component 3, increasing the adaptability of the fixing device to different infusion filters.

[0044] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto.
