[0023] Example:
[0024] As attached Figure 1 To Attachment Figure 3 As shown:
[0025] The utility model provides a disposable filtering intravenous nutrition infusion bag, comprising an infusion bag body 1, a filter 2 and a first liquid inlet pipe 3, an infusion pipe 4 is installed on one side of the bottom end of the infusion bag body 1, a second liquid inlet pipe 5 is installed on the other side of the bottom end of the infusion bag body 1, a connecting pipe 6 is inserted at the bottom end of the second liquid inlet pipe 5, sleeves 7 are installed at both ends of the filter 2, a filter screen 8 is installed inside the filter 2, external threads 9 are provided at both ends of the filter 2, a plurality of liquid extraction pipes 10 are installed at the bottom end of the first liquid inlet pipe 3, a liquid extraction head 11 is installed at the bottom end of the liquid extraction pipe 10, and fixing components are installed at the top end of the first liquid inlet pipe 3 and the bottom end of the connecting pipe 6.
[0026] The sizes of the pair of sleeves 7 respectively match the sizes of the connecting pipe 6 and the first liquid inlet pipe 3, so that the connecting pipe 6 and the first liquid inlet pipe 3 can be quickly inserted into both ends of the filter 2, thereby improving work efficiency.
[0027] Among them, the fixing component includes a pair of sliding covers 12 and a pair of limit blocks 13. The pair of sliding covers 12 are slidably installed on the bottom end of the connecting pipe 6 and the top end of the first liquid inlet pipe 3 respectively. The inner side of the sliding cover 12 is provided with an internal thread 14. The pair of limit blocks 13 are respectively installed at a position near the bottom end of the peripheral side of the connecting pipe 6 and a position near the top end of the peripheral side of the first liquid inlet pipe 3. When connecting the filter 2 between the connecting pipe 6 and the first liquid inlet pipe 3, the medical staff slides the sliding cover 12 to make the sliding cover 12 close to the filter 2, and then rotates the sliding cover 12. Since the internal thread 14 matches the external thread 9, the sliding cover 12 can be fixed on the filter 2, and during the rotation, the sliding cover 12 contacts the limit block 13 and pushes the limit block 13 in the direction of the filter 2, so that the connecting pipe 6 and the first liquid inlet pipe 3 are respectively tightly attached to the sleeve 7, thereby improving the stability of the connecting pipe 6 and the first liquid inlet pipe 3 when connected to the sleeve 7.
[0028] The size of the sliding cover 12 matches the size of the filter 2 .
[0029] The internal thread 14 matches the external thread 9 , so that a pair of sliding covers 12 can be fixed at both ends of the filter 2 respectively.
[0030] A sealing plug 15 is installed on the peripheral side of the second liquid inlet pipe 5 .
[0031] A hanging ring 16 is provided at the top of the infusion bag body 1 .
[0032] The working principle of this embodiment: when using the disposable filtering intravenous nutrition infusion bag, the medical staff first takes out the infusion bag body 1, the first liquid inlet pipe 3 and the filter 2 from the package, and then aligns one end of the connecting pipe 6 and one end of the first infusion pipe 4 with the sleeves 7 at both ends of the filter 2 and inserts them into the sleeves 7. After insertion, slide a pair of sliding covers 12 respectively to make the sliding covers 12 close to the filter 2, and then rotate the sliding covers 12. Since the internal thread 14 matches the external thread 9, the sliding covers 12 can be fixed on the filter 2, and during the rotation, the sliding covers 12 contact the limit block 13 and push the limit block 13 in the direction of the filter 2, so that the connecting pipe 6 and the first liquid inlet pipe 3 are respectively in close contact with the sleeve 7, thereby improving the stability of the connecting pipe 6 and the first liquid inlet pipe 3 when connected to the sleeve 7. After the fixation is completed , the medical staff inserts the liquid collection head 11 into the medicine bottle to collect liquid. During the process of collecting liquid, the medicine liquid first enters the filter 2 from the first liquid inlet pipe 3, and the filter mesh 8 inside the filter 2 can filter out the fine debris and sundries in the liquid. The filtered liquid enters the infusion bag body 1 from the connecting pipe 6 and the second liquid inlet pipe 5 to realize liquid filling. If during the liquid filling process, there are too many debris in the liquid and the filter 2 is blocked, the medical staff can rotate the pair of sliding covers 12 in the opposite direction to separate the pair of sliding covers 12 from the filter 2 respectively, and then pull the first liquid inlet pipe 3 and the connecting pipe 6 out of the sleeve 7 respectively, and then remove the filter 2 and replace it with a new filter 2. After the liquid filling is completed, the medical staff removes the connecting pipe 6 and closes the second liquid inlet pipe 5 with the sealing plug 15, and then the infusion bag body 1 can be transported or used.

Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific purposes.
