Problems solved by technology
These operations are often very troublesome, not only require experienced medical staff to operate, but also prone to accidents such as pull-off accidents
As a result, not only is the medicinal solution wasted, but also it is easy to cause iatrogenic infection, and even if such a method is used for processing, it only solves the problem of re-infusion. As well as the risk of serious injuries such as iatrogenic infection and sepsis, it is still impossible to fundamentally solve the problem

Embodiment 1
[0034] A specific embodiment of a precision filter infusion set of the present invention, such as figure 1 As shown, it includes a cork piercer 100, a cork piercer protective cover 200, an air filter 300, an air inlet pipe 400, an upper conduit 500, a three-way pipe 600, a dropping funnel 700, a downcomer 800, a flow regulator 900, Medical solution filter 1000 , infusion needle thin tube 1100 and intravenous infusion needle 1200 .
[0035] When in use, unplug the cork piercer protective cover 200, insert the cork piercer 100 into the socket of the infusion bag or the infusion bottle, and after the anti-bleed precision infusion set is emptied of air, place the flow regulator 900 in the closed position, Then the fine vein infusion needle 1200 is punctured into the patient's venous blood vessel, and then the flow regulator 900 is adjusted to the required infusion speed. 600 enters the dripping funnel 700, and then enters the infusion needle thin tube 1100 from the dripping funne...
Embodiment 2
[0044] A specific embodiment of a precision filter infusion set of the present invention, its main structure is the same as that of Example 1, the difference is that, as figure 2 As shown, the precision filter 10 is provided with a selective infusion device 110 , and the rotary infusion device 110 is fixed on the filter mounting base 120 .
[0045]The selective infusion device 110 can automatically select and adjust the infusion flow rate according to the liquid volume in the dropping funnel 700 . When there is still liquid in the infusion bag or infusion bottle, liquid will be continuously replenished in the drip funnel 700. Therefore, the liquid level in the drip funnel 700 will be at a higher position, and the infusion device 110 will be selected at the required normal infusion rate. Infusion, that is, to output liquid with a large flow rate. After the liquid in the infusion bag or the infusion bottle is transfused, the remaining liquid in the dripping funnel 700 will gra...
Embodiment 3
[0050] A specific embodiment of a precision filter infusion set of the present invention, its main structure is the same as that of Example 2, the difference is that, as image 3 As shown, the optional infusion device is also provided with an easy-to-vent pipe 113 , and the easy-to-vent pipe 113 is fixed to the filter mounting seat 120 . The easy exhaust pipe 113 is provided with an exhaust input end and an exhaust output end, the exhaust input end is higher than the main infusion input end of the main infusion tube 111 , and there is a gap between the exhaust output end and the filter membrane 149 . The setting of the easy exhaust pipe 113 is beneficial to the gas circulation in the dropping funnel and facilitates the discharge of the medicinal liquid.
[0051] When the liquid level in the dropping funnel 700 was higher, the main infusion tube 111, the slow infusion tube 112 and the easy exhaust tube 113 were infused together, and this precision filter infusion set will be in...

Abstract
The invention relates to a precise filtering infusion apparatus comprising a three-way pipe, a drop bucket, and a conduit, wherein the lower part of the drop bucket is provided with a precise filter, and the precise filter is provided with a filtering film, an upper cover, an infusion selecting device, and a filter installing holder. The filtering film can allow fluid to pass through, but prevent air from passing through. The infusion selecting device can be provided with a main infusion pipe, a slow infusion pipe and an easy air discharge pipe. The upper part of the main infusion pipe can be provided with an air blocking slot, the inside of the upper cover can be provided with a fixed frame, the filter installing holder can be also provided with a fixed frame which is fixed on the filter installing holder. When the liquid in an infusion bag or an infusion bottle of the precise filtering infusion apparatus is thoroughly infused, the liquid in the drop bucket of the infusion apparatus can be slowly infused. When the liquid in the drop bucket is run out after a long period, the slow liquid infusion can be still carried out because of the function of the filtering film. The filtering film can efficiently prevent air from entering into the conduit, and can only make the liquid enter into the conduit, thereby truly preventing the happening of the blood backflow phenomenon.
Description
technical field [0001] The invention relates to an infusion set technology, in particular to a precision filter infusion set. Background technique [0002] In the clinical treatment process, many patients often need to carry out transfusion, so as to treat diseases and rescue patients by the treatment means of transfusion. Thereby, need a large amount of use infusion sets. [0003] In the prior art, in the traditional infusion set, after the infusion of the liquid in the infusion bag or the infusion bottle is completed, the needle needs to be pulled out immediately. If the needle is not pulled out in time, the phenomenon of blood backflow will occur. Especially if air enters the downcomer of the infusion set due to negligence or when it is too late to replace liquids such as new medicinal solution or blood, unexpected blood return will occur. The occurrence of blood return will not only cause the catheter to be unable to continue infusion due to air bubble embolism, but m...
