A third through hole 11 is opened on the inner side of the internally threaded lower cover 10. A second connecting pipe 12 is arranged on the inner side of the third through hole 11. A heat insulating sleeve 13 is sleeved on the outer side of the protective sleeve 1, and a heat insulating pad 14 is arranged between the heat insulating sleeve 13 and the protective sleeve 1. A fixing ring 15 is fixedly connected to the inner side of the protective sleeve 1, and a filtering textile mesh 16 composed of a plurality of textile threads is fixedly connected between a group of fixing rings 15.
[0027] The inner circle of the fixed ring 15 is provided with filter cotton 17, and the filter cotton 17 is symmetrically arranged on both sides of the filter textile net 16. This arrangement adds filter cotton 17 to the inner side of the protective soft sleeve 1, thereby enhancing the blood filtering effect of the blood filtering textile equipment; the thermal insulation pad 14 is fixedly connected to the outer wall of the protective soft sleeve 1, and the outer wall of the protective soft sleeve 1 is fixedly connected to the thermal insulation sleeve 13. This arrangement enables the thermal insulation sleeve 13 to block the cold wind from acting on the protective soft sleeve 1 in a cold environment, causing the inactivation of the blood inside the protective soft sleeve 1. The thermal insulation pad 14 can enhance the thermal insulation effect of the protective soft sleeve 1 and maintain the activity of the blood to a certain extent; the lower end face of the upper cover 4 is in contact with the upper end face of the internal threaded ring 2, the internal threaded ring 2 is connected to the first connecting pipe 8 and the air pressure pipe 7, and the second external threaded ring 9 is connected to the second connecting tube 12. Through the arrangement of the air pressure tube 7, after the needle is inserted into the human body, the internal volume of the protective soft sleeve 1 is larger than that of the infusion tube, so that its air pressure can be detected more accurately, which is convenient for accurately judging whether the blood vessel position of the patient's needle insertion is correct; the outer sides of the first connecting tube 8 and the air pressure tube 7 are both sleeved with a first sealing sleeve 18, and the first sealing sleeve 18 is fitted with the upper end surface of the upper cover 4, and the outer side of the second connecting tube 12 is sleeved with a second sealing sleeve 19, and the second sealing sleeve 19 is fitted with the lower end surface of the internal thread lower cover 10.

After preliminary filtration by the filter cotton 17, the blood acts on the filter textile mesh 16 composed of a number of textile threads. The fats and purines that cannot be metabolized will adhere to the filter textile mesh 16 used for filtration, and then pass through the filter cotton 17 on the inner side of the fixing ring 15 close to the side of the internal threaded ring 2. It is filtered again, and then flows in the direction of the first externally threaded ring 3, and finally flows out from the first connecting tube 8 at the second through hole 6, thereby realizing the blood filtering textile equipment to filter the blood. The air pressure tube 7 in the first through hole 5 opened on the inner side of the upper cover 4 makes the protective sleeve 1 have a larger internal volume than the infusion tube after the needle is inserted into the human body, so that its air pressure can be detected more accurately, which is convenient for accurately judging whether the position of the patient's needle insertion blood vessel is correct. The heat-insulating sleeve 13 can block the cold wind from acting on the protective sleeve 1 in a cold environment, causing the inactivation of the blood inside the protective sleeve 1. The thermal insulation pad 14 can enhance the thermal insulation effect of the protective sleeve 1, and maintain the activity of the blood to a certain extent.
