Problems solved by technology

[0002] The disposable venous indwelling needles used clinically in clinical units of various medical institutions in China need to be sealed after the infusion to avoid clogging caused by blood coagulation in the tube. If the tube is not flushed before the next day's infusion, or the clot that has formed is flushed into the blood vessel, it is very easy to cause embolism in the blood vessel blocked during the blood circulation process. The patient brings great harm or even life-threatening. Although some patients are injected with anticoagulant drugs such as heparin sodium to prevent blood coagulation, and some patients who are allergic to anticoagulant drugs such as heparin sodium m

Embodiment 1

[0023] like figure 1 , figure 2 , image 3 Figure 4 and Figure 5 Shown, the present invention is made of protective cap (12), screw joint (1), front conduit (2), front tee (3), sustained release conduit (5), middle conduit (4), clip (6), rear Tee (7), rear conduit (8), tee seat (9), positive pressure joint (11) and liquid reservoir (10), the clip (6) is set on the middle conduit (4), and the slow-release conduit (5), the two ends of the middle conduit (4) are respectively connected with the double hole ends of the front tee (3) and the back tee (7), and the front conduit (2) is connected with the single hole and the front tee (3) respectively. The small end of the screw joint (1) is connected, the large end of the screw joint (1) is screwed to the protective cap (12), and the rear conduit (8) is connected to the single hole end of the rear tee (7) and the tee seat (9) respectively. The front part is connected, and the positive pressure joint (11) and the liquid reservo...

Embodiment 2

[0035] like Figure 5 As shown, embodiment 2 of the present invention differs from embodiment 1 in that it consists of the needle assembly (16) of the Y-shaped indwelling needle, the catheter assembly (15) of the Y-type indwelling needle, the front catheter (2), and the front tee (3) , sustained-release catheter (5), middle catheter (4), clip (6), rear tee (7), rear catheter (8), tee seat (9), heparin cap (14) and reservoir (10 ), the clip (6) is set on the middle catheter (4), the two ends of the slow-release catheter (5) and the middle catheter (4) are respectively connected with the double-hole ends of the front and rear tees, and the front catheter (2) is respectively Connect with the single hole of the front tee (3) and the catheter assembly (15) branch pipe end of the Y-shaped indwelling needle, and the rear catheter (8) is connected with the single hole end of the rear tee (7) and the tee seat (9) respectively. The front part is connected, and the heparin cap (14) and ...

Abstract

The invention discloses an indwelling needle controlled-release positive pressure device which comprises a protecting cap, a spiral joint, a front guide pipe, a front tee joint, a controlled-release guide tube, a middle guide tube, a clamp, a rear tee joint, a rear guide tube, a tee joint seat, a positive pressure joint and a liquid storage device. The clamp sleeves the middle guide tube, two ends of the controlled-release guide tube and the middle guide tube are connected with two-hole ends of the front tee joint and the rear tee joint respectively, and other accessories are connected with one another. The indwelling needle controlled-release positive pressure device is characterized by being provided with the two guide tubes, and one is the controlled-release guide tube with a micro hole in the middle while another one is the middle guide tube universal in hole diameter. When the middle guide tube is clamped by the clamp, hydraulic pressure released by the positive pressure joint and the liquid storage device forms pressure, medicine liquid slowly flows out from the micro hole of the controlled-release guide tube to an indwelling needle guide tube component to seep into a blood vessel, and forming of thrombus can be effectively prevented. In addition, when infusion is needed again in the second day, normal infusion can be performed by sterilizing a connecting position, connecting and opening the clamp on the middle guide tube.

Description

technical field [0001] The invention relates to a disposable medical device, in particular to a slow-release positive pressure device for an indwelling needle. Background technique [0002] The disposable venous indwelling needles used clinically in clinical units of various medical institutions in China need to be sealed after the infusion to avoid clogging caused by blood coagulation in the tube. If the tube is not flushed before the next day's infusion, or the clot that has formed is flushed into the blood vessel, it is very easy to cause embolism in the blood vessel blocked during the blood circulation process. The patient brings great harm or even life-threatening. Although some patients are injected with anticoagulant drugs such as heparin sodium to prevent blood coagulation, and some patients who are allergic to anticoagulant drugs such as heparin sodium may also use normal saline to seal the tube. The tube time is limited, and it needs to be sealed many times. In ad...
