Embodiment 1

[0027] Such as figure 1 As shown, an indwelling catheter antithrombotic device includes a positive pressure chamber 1, a slow release valve 2 and a joint 3 integrated into one body. The positive pressure chamber 1 is a hollow tube with a closed end and the other end communicated with the joint 3. The joint 3 is a conical joint with a taper of 6:100, or a joint that can be connected to the outer end of the indwelling catheter in a puncture manner. The positive pressure chamber 1 and the joint 3 are connected through the slow release valve 2. The positive pressure chamber 1 Divided into a driving 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 load, 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 liquid 121 in the liquid cavity 12 flows out at such a speed that it is slowly rel...

Embodiment 2

[0035] Such as figure 2 As shown, an indwelling catheter antithrombotic device includes a positive pressure chamber 1, a slow release valve 2 and a joint 3 integrated into one body. The positive pressure chamber 1 is a hollow tube with a closed end and the other end communicated with the joint 3. The joint 3 is a conical joint with a taper of 6:100, or a joint that can be connected to the outer end of the indwelling catheter in a puncture manner. The positive pressure chamber 1 and the joint 3 are connected through the slow release valve 2. The positive pressure chamber 1 Divided into a driving chamber 11 and a liquid storage chamber 12 .

[0036] Wherein, the slow-release valve 2 is a filter medium or a filter medium and its load, 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 liquid 121 in the liquid cavity 12 flows out at such a speed that it is slowly ...

Embodiment 3

[0043] Such as image 3 As shown, an indwelling catheter antithrombotic device includes a positive pressure chamber 1, a slow release valve 2 and a joint 3 integrated into one body. The positive pressure chamber 1 is a hollow tube with a closed end and the other end communicated with the joint 3. The joint 3 is a conical joint with a taper of 6:100, or a joint that can be connected to the outer end of the indwelling catheter in a puncture manner. The positive pressure chamber 1 and the joint 3 are connected through the slow release valve 2. The positive pressure chamber 1 Divided into a driving chamber 11 and a liquid storage chamber 12 .

[0044] Wherein, the slow-release valve 2 is a filter medium or a filter medium and its load, 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 liquid 121 in the liquid cavity 12 flows out at such a speed that it is slowly r...

Abstract

The invention belongs to the technical field of medical instruments, in particular to a thrombus prevention device with an indwelling catheter. A device comprising a positive pressure chamber, a slow-release valve and a joint which are combined into a whole is arranged, the positive pressure chamber is divided into a driving cavity and a liquid storage cavity, and liquid can be filled into the liquid storage cavity in advance or is filled into the liquid storage cavity during use; by use of the inherent bubble point characteristic of a filtering medium, the bubble point numerical value of the filtering medium is regulated, a resistance which is less than or equal to the pressure of the positive pressure chamber is formed, The resistance limits that the liquid which is in a positive-pressure driving state in the liquid storage cavity can only be slightly and slowly released and filled into the joint so as to further enter into the indwelling catheter, so that the positive-pressure slow-release time of the liquid in the liquid storage cavity is greatly prolonged, the indwelling catheter connected with the liquid storage cavity is in a positive-pressure state for a long time, and thus the purpose of preventing blood from flowing back to the indwelling catheter so as to prevent formation of thrombus is achieved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an indwelling catheter anti-thrombosis device used to prevent blood reflux and form thrombus during indwelling catheters for infusion in blood vessels. device. Background technique [0002] As an alternative to intravenous infusion needles, intravenous indwelling needles were first used clinically in 1958 with the safety concept of needle-free infusion. So far, indwelling needles including PICCs have been widely used. The intravenous indwelling needle is mainly composed of a puncture steel needle and an indwelling catheter. It is named because the indwelling catheter is left in the human vein for the next infusion. However, with the extensive use of indwelling needles, the hidden risks of indwelling catheters have gradually been reported. These problems are clotting and occlusion of the indwelling catheter and have been found to be common concomitant problems of IV cath...
