Problems solved by technology

During the infusion process, it is necessary to use the piercer to penetrate the infusion bottle, and fix the exhaust branch with the air filter facing upwards. Therefore, it sometimes happens that the exhaust branch with the air filter is forgotten to be fixed again, or it is not fixed properly. OK, resulting in pipeline discounts or air filter leakage, affecting normal infusion, reducing infusion efficiency, and even causing pollution
Due to the no-handle position of the puncture device connected to the exhaust branch with air filter, the labor intensity of puncture operation during infusion is also increased
[0003] In addition, ordinary bag-type infusion sets are basically made of polyvinyl chloride (PVC), and PVC plastic itself is relatively hard, so it is not suitable for infusion set components such as catheters and drip funnels, so a large amount of plasticizer needs to be added to it and other additives to make it soft and elastic
But this bag-type infusion set that utilizes modified PVC plastics to make, wherein as dropping funnel, conduit etc. when directly contacting with medicinal liquid, the plasticizer in this PVC plastics, stabilizing agent etc. will ooze. out, contaminate the liquid medicine and chemically react with the liquid medicine to generate harmful substances, which will damage the patient's health and therapeutic effect to a certain extent
It is difficult to incinerate ordinary bag-type infusion sets made of discarded polyvinyl chloride materials. Burial will cause serious soil pollution. Hydrogen chloride and dioxin gas will also be produced during the incineration process. Hydrogen chloride will form acid rain and dioxins. British gas is a carcinogen, therefore, the environmental protection of ordinary bag infusion sets is poor
[0004] Finally, although a filter screen is installed in the drip funnel of an ordinary bag-type infusion set, the filter screen is installed in the inner cavity of the drip funnel, which shares the same inner space with the drip funnel, and the infusion fluid first passes through the drip funnel. After being filtered by the filter, it flows out from the drip funnel, and the flowing infusion fluid has a certain oppressive effect on the filter
Therefore, when the large particle size impurities in the infusion fluid enter the inner space of the dripping funnel, they are easily deposited on the filter screen, thus causing the filter screen to be easily blocked
If the dripping funnel is forcibly squeezed, it is easy to squeeze the impurities out of the filter screen and eventually enter the human body with the flowing infusion fluid, which will have a negative impact on the safety of the infusion. Therefore, there is a certain safety risk

Embodiment 1

[0028] Such as figure 1 A safety bag type infusion set shown is composed of a puncture device 4, a first connecting hose 2, a liquid distribution bag 1, a second connecting hose 5, a dropping funnel 10, a third connecting hose 7 and a liquid medicine The filter 8 and the infusion needle 9 are sequentially fixedly connected to form a closed pipeline system. Wherein, the concrete structure of described piercer 4 is as follows: figure 2 , image 3 , Figure 4 As shown, it includes a piercer body 47, a grip 41, a fixed bracket 45 with a through hole, and a fixed cover 46. The free end of the piercer body 47 is a puncture head 44, and the grip 41 is trapezoidal. Its relatively large end is fixedly connected with the puncture device body 47, which is convenient for the operator to apply sufficient force to the puncture head 44 through the grip part 41, improves the puncture efficiency of the puncture device 4, and is also conducive to reducing the labor during the puncture opera...

Embodiment 2

[0040] Such as Figure 5 , Image 6 In the shown bag type infusion set, an elastic ball 12 is sleeved on the first connecting hose 2 as a flow regulating device. The elastic ball 12 is provided with a through hole 14 , and the first connecting hose 2 passes through the through hole 14 . In order to facilitate the direct and fast closing operation of the first connecting hose 2 , a liquid stop clamp 13 may be additionally provided on the first connecting hose 2 . As for the flow regulating device on the third connecting hose 7, the elastic ball 12 can be used with reference to the first connecting hose 2 and used in conjunction with the liquid stop clip 13, or a roller-type flow regulator can be used. Other structures are with embodiment 1.

[0041] Compared with Embodiment 1, when the bag type infusion set in this embodiment is performing infusion operation, if it is necessary to adjust the fluid flow in the first connecting hose 2 or the third connecting hose 7, only the el...

Embodiment 3

[0043] Such as Figure 7 In the shown bag type infusion set, a section of bellows 15 is connected to the first connecting hose 2, and an elastic ball 12 is installed in the inner cavity of the bellows 15 as a flow regulating device, and a through hole is arranged on the elastic ball 12 14 communicates with the first connecting hose 2. In order to facilitate the direct and fast closing operation of the first connecting hose 2 , a liquid stop clamp 13 may be additionally provided on the first connecting hose 2 . As for the flow regulating device on the third connecting hose 7, the elastic ball 12 can be used with reference to the first connecting hose 2 and used in conjunction with the liquid stop clip 13, or a roller-type flow regulator can be used. Other structures are with embodiment 1.

Abstract

The invention provides a safety bag type infusion set which comprises a drip chamber (10) and a puncture set (4). The top end of the puncture set (4) is provided with a puncture head, the tail end of the puncture set (4) is in sealed and fixed connection with a liquid dividing bag (1) through a first connecting hose (2), the first connecting hose (2) is provided with a flow adjusting device, an inner cavity of the drip chamber (10) is internally fixedly connected with a partition plate (103), the partition plate (103) divides the inner cavity of the drip chamber (10) into a filtering cavity (102) and a collecting cavity (106), a conduit (104) is fixedly installed on the partition plate (103) and enables the filtering cavity (102) to be connected with the collecting cavity (106), and a filter screen (11) is fixedly installed in the filtering cavity (102). Through the appropriate squeezing of the filtering cavity on the drip chamber, impurities deposited on the filter screen are separated from the filter screen, the output flow in a pipeline recovers to be normal; the impurities cannot penetrate the filter screen in a forcing mode to be finally output to the human body, and the reliability and the safety are high.
