[0002] Blood sedimentation refers to the process of separating and extracting different components in the blood during the blood preparation process, and then storing some of the components in the form of sediments for use when needed. Before blood sedimentation is stored, white blood cells need to be filtered out in advance through a filter to reduce the impact on the quality of subsequent blood sedimentation storage.

[0003] At present, a Chinese patent discloses a blood leukocyte removal filter device (publication number CN219148729U). The utility model effectively improves the leukocyte removal effect of the filter element by cooling the blood in the filter element through a deformable thermoelectric cooler.

[0004] Since the above device indirectly cools the blood by refrigerating the filter element, and the above device increases the flow rate of the blood by a booster pump, it is easy to cause the blood to be filtered before it is cooled to a specified temperature. At this time, the white blood cells may still be an ellipsoid or even an elongated body, which makes the filter material's capture effect on them still poor, and the filtration effect is still poor.

[0025] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0026] See also Figure 1 - Figure 4As shown, the utility model provides a blood sedimentation preservation and processing filter, including: a booster pump 1, a catheter 2 and a filter element 3, the booster pump 1 is fixedly connected and connected to one end of the catheter 2, the filter element 3 is fixedly connected and connected to the other end of the catheter 2, and a cooling device 4 is sleeved on the surface of the catheter 2; wherein the cooling device 4 includes a heat preservation mechanism 41 and a cooling mechanism 42, the heat preservation mechanism 41 is sleeved on the surface of the catheter 2, the cooling mechanism 42 is installed at one end of the heat preservation mechanism 41, and one end of the cooling mechanism 42 passes through the outside of the heat preservation mechanism 41, the filter element 3 used here is the same as the filter element used in the comparative case in structure and model, and is a commonly used device for filtering white blood cells in blood, which will not be described here.

[0027] like Figure 2 and Figure 3 As shown, the heat preservation mechanism 41 includes two heat preservation plates 411, the two heat preservation plates 411 are fitted together, and the opposite ends of the two heat preservation plates 411 are provided with relatively aligned mounting grooves 412, and the two mounting grooves 412 are both clamped with the liquid guide tube 2; the horizontal cross-sectional shape of the mounting groove 412 and the local horizontal cross-sectional shape of the heat conduction tube 423 inside the mounting groove 412 are both matched serpentine, which can increase the contact area between the heat conduction tube 423 and the liquid guide tube 2, and further improve the cooling effect on the blood; the heat preservation mechanism 41 also includes an adjusting bolt 413, which is adjusted The joint bolt 413 is rotatably connected to the top of the upper insulation plate 411, and the bottom of the adjusting bolt 413 passes through the upper insulation plate 411 and is threadedly connected to the lower insulation plate 411. The two insulation plates 411 are fixedly connected by the adjusting bolt 413, which enables medical staff to replace the catheter 2 according to needs, thereby expanding the practicality of the insulation mechanism 41; the insulation mechanism 41 also includes an adjusting rod 414, which is fixedly connected to the top of the adjusting bolt 413, and the corners of the adjusting rod 414 are rounded, which makes the adjustment operation of medical staff easier;

[0028] When the medical staff needs to install the catheter 2 into the installation groove 412, the medical staff first rotates the adjusting bolt 413 in the corresponding direction and screws the adjusting bolt 413 out of the lower insulation plate 411. At this time, the two insulation plates 411 lose connection, and the medical staff can bend the catheter 2 and insert it into the lower installation groove 412, and then screw the adjusting bolt 413 into the lower insulation plate 411, and make the upper installation groove 412 and the catheter 2 engage until the upper and lower insulation plates 411 fit together. At this time, the catheter 2 is firmly locked in the installation groove 412.

[0029] like Figure 2 , Figure 3 and Figure 4As shown, the cooling mechanism 42 includes a water chiller 421, an infusion pump 422 and two heat-conducting pipes 423. The infusion pump 422 is fixedly connected and communicated with the liquid outlet of the water chiller 421. The two heat-conducting pipes 423 are fixedly connected and communicated with the liquid outlet of the infusion pump 422. One end of the heat-conducting pipe 423 passes through the insulation board 411 and the mounting groove 412 in sequence and is fixedly connected and communicated with the liquid inlet end of the water chiller 421. The opposite ends of the two heat-conducting pipes 423 are in contact with the liquid-conducting pipe 2. The local material of the heat-conducting pipe 423 inside the mounting groove 412 is a copper alloy material component, and the local material of the heat-conducting pipe 423 outside the mounting groove 412 is a butyl rubber material component. When the cooling water is inside the mounting groove 412, the local heat-conducting pipe 423 made of copper alloy can improve the heat conduction efficiency, thereby improving the cooling effect on the blood. When the cooling water is outside the mounting groove 412, the local heat-conducting pipe 423 made of butyl rubber can improve the heat conduction efficiency, thereby improving the cooling effect on the blood. The local heat-conducting pipe 423 can prevent the external heat from penetrating into the tissue to achieve a good insulation effect, and the local heat-conducting pipe 423 made of butyl rubber can be bent under force, so that medical staff can easily move the insulation board 411, and the heat-conducting pipe 423 outside the insulation board 411 is also deformed accordingly; the vertical cross-sectional shape of the local end face of the heat-conducting pipe 423 in contact with the liquid catheter 2 is an arc shape, and the corners of the heat-conducting pipe 423 are rounded, which can increase the contact area between the heat-conducting pipe 423 and the liquid catheter 2, and further improve the cooling effect of the blood inside the liquid catheter 2; the cooling mechanism 42 also includes a diverter valve 424, the liquid inlet end of the diverter valve 424 is fixedly connected and communicated with the liquid outlet end of the infusion pump 422, and the liquid inlet ends of the two heat-conducting pipes 423 are fixedly connected and communicated with the liquid outlet end of the diverter valve 424, which can evenly pour cooling water into the two heat-conducting pipes 423, so that the blood is cooled more evenly.

[0030] Working principle: the water chiller 421 quickly cools the water inside it, and then the infusion pump 422 delivers the cooling water into the two heat pipes 423. In the process of the cooling water passing through the heat pipes 423, the cooling water absorbs the heat of the liquid pipe 2 through the heat pipes 423, so that the liquid pipe 2 in contact with the heat pipe 423 is always in a low temperature state. After the cooling water absorbs the heat, the cooling water returns to the water chiller 421 along the heat pipes 423 to be cooled again for recycling. At this time, the entire cooling mechanism 42 continuously absorbs the heat of the liquid pipe 2. After the booster pump 1 delivers the blood into the interior of the liquid pipe 2, the heat in the blood quickly flows into the liquid pipe 2, so that the blood entering the filter element 3 through the liquid pipe 2 is always in a preset low temperature state. At this time, the white blood cells in the blood return to their original state, thereby ensuring the normal filtering effect of the filter element 3 on the white blood cells in the blood.

[0031] It should be noted that the booster pump 1, water chiller 421, infusion pump 422 and diverter valve 424 in the above description are all devices with relatively mature application of existing technologies. The specific models can be selected according to actual needs. At the same time, the booster pump 1, water chiller 421 and infusion pump 422 can be powered by a built-in power supply or by AC power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0032] The above are only specific implementations of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
