Embodiment 1
[0031] Embodiment 1: An antithrombotic venous indwelling needle and its antithrombotic method, such as figure 1 , figure 2 and image 3 As shown, it includes a needle hub 1 , an indwelling hose 2 sealingly connected to the top end of the needle hub 1 , and a puncture needle 3 penetrating into the indwelling hose 2 from the bottom end of the needle hub 1 . The end of the indwelling hose 2 is located in the needle hub 1 and communicates with the inner cavity of the needle hub 1 . The inner cavity of the needle base 1 is installed with a first rubber sealing plug 4 and a second rubber sealing plug 5, the first rubber sealing plug 4 is located in the middle and upper part of the inner cavity of the needle base 1, and the second rubber sealing plug 5 is located in the inner cavity of the needle base 1. middle and lower part. The first rubber sealing plug 4 and the second rubber sealing plug 5 divide the inner chamber of the needle hub 1 into an infusion chamber 6 , a positive p...
Embodiment 2
[0047] Embodiment 2: An antithrombotic intravenous indwelling needle antithrombotic method, the specific steps are:
[0048] 1) First, insert the infusion needle of the infusion device into the heparin cap 24 at the end of the infusion tube 28 to connect the infusion device with the antithrombotic intravenous indwelling needle, and then send the indwelling hose 2 and the puncture needle 3 into the patient through the needle holder handle 26 Pull out the puncture needle 3 behind the blood vessel, so that the puncture needle 3 leaves micro-needle holes on the first rubber sealing plug 4 and the second rubber sealing plug 5 respectively.
[0049] 2) During the intravenous infusion of the patient, use the indwelling needle warming device 14 sleeved on the outer wall of the first catheter tube 12 of the indwelling needle to heat up the indwelling needle, and fix the heating strap 15 at a distance of 3 from the puncture needle. Patient's limb at 20cm from the puncture point, heat up...
