[0026] Example 1
[0027] Such as figure 1 As shown, an indwelling catheter thrombosis prevention device includes a positive pressure chamber 1, a slow-release valve 2 and a joint 3 that are combined into one body. The positive pressure chamber 1 is a hollow tube with a closed end and a joint 3 at the other end. The connector 3 is a 6:100 taper conical connector, or a connector that can communicate with the outer end of the indwelling catheter in a puncture manner, the positive pressure chamber 1 and the connector 3 are connected via a slow release valve 2, and the positive pressure chamber 1 It is divided into a drive cavity 11 and a liquid storage cavity 12.
[0028] Wherein, the slow-release valve 2 is a filter medium or a filter medium and its carrier, and the filter medium involved is a filter medium with a bubble point ≤ the pressure value of the positive pressure chamber, and its function is to control the storage The flow rate of the liquid 121 in the liquid chamber 12 is ...
