Problems solved by technology

[0005] In order to overcome the above-mentioned deficiencies of the hemostatic infusion set, the present invention proposes an anticoagulant hemostatic infusion set with a flow changer, which can make the hemostatic infusion set keep the intravenous injection needle within a few hours of stopping the liquid. A small amount of infusion can be infused into the vein all the time, so it can not only avoid the above-mentioned coagulation phenomenon at the intravenous injection needle due to the long stoppage time, but also avoid the blood coagulation caused by the infusion set when the nurse comes to deal with the infusion set in time. The liquid stop time is too short to drain the remaining infusion in the drip funnel, resulting in the waste of infusion

Embodiment 1

[0019] Such as figure 1 Shown is a central longitudinal section view of an anticoagulant hemostatic infusion set with a flow converter. The cork puncture 1 is connected to the infusion tube 2, the upper infusion tube 2 is connected to the dropper 3, the dropper 3 and the dropper The bucket cover 15A is connected.

[0020] A hollow exhaust pipe 5 is inserted into the lower neck of the drip hopper 15 and extends into the cavity of the drip hopper 15 at both ends, and an exhaust hole 4C is provided at the upper end of the side wall of the exhaust pipe 5 , The position of the exhaust hole 4C is set between 1 / 2 and 2 / 3 of the height of the drip tube. The upper bottom surface of the exhaust pipe 5 is a drainage slope 4 set in a direction away from the exhaust hole 4C. At the edge of the drainage slope 4 on the side of the exhaust hole 4C, a long baffle plate 4A is formed extending in a direction away from the drainage slope 4. The elongated baffle plate 4A is composed of a long strip...

Abstract

The invention discloses an anticoagulant liquid stop infusion apparatus with a flow changing switch. The anticoagulant liquid stop infusion apparatus comprises a bottle stopper puncture device, an upper infusion tube, a dropper tube, a drip chamber, an exhaust tube, a lower infusion tube, a liquid medicine stop filter, a drainage tube, a liquid guide hole, a flow changing switch, an external conical joint, a capillary infusion tube, a flank and an intravenous injection needle and is characterized in that the exhaust pipe is upwards in plugged connection with the lower neck portion of the drip chamber, the liquid guide hole is formed in a lower bottom support of the drip chamber, the drainage tube is connected with the liquid guide hole and the liquid medicine stop filter through a convex tube B and a convex tube A, and the flow changing switch is arranged in the interval between the convex tube A and the convex tube B. The anticoagulant liquid stop infusion apparatus can stop infusing after liquid is infused completely, coagulation occurred at the position of the intravenous injection needle due to too long liquid stop time can be avoided, and another problem caused by coagulation occurred at the position of the intravenous injection needle due to too long liquid stop time can be avoided. If the liquid stop time is short, remaining liquid in the drip chamber cannot be infused completely, and liquid waste is caused.

Description

【Technical Field】 [0001] The invention relates to a disposable infusion device, and is particularly suitable for a disposable anticoagulation and liquid stop infusion device. 【Background technique】 [0002] In the current stop fluid infusion device, after the stop fluid starts, there is no infusion again and then infused into the vein through the intravenous needle. For ordinary patients, after a period of hemostasis, if there is no nurse to deal with it, blood clots will occur at the intravenous needle. In addition, in severely ill patients of almost all diseases, coagulation disorders will occur. If this This kind of patient uses a hemostatic infusion device. After the liquid is stopped, the intravenous needle will clot within a short period of time. Once a blood clot occurs, it will panic the patient and even cause medical disputes. [0003] In order to solve this problem, an exhaust pipe with a micro flow hole is inserted in the lower neck of the drip hopper, and an exhaust p...
