Embodiment 1

[0054] like figure 1 , 2 As shown, its liquid inlet interface is composed of a side hole needle 1, a dropper 2, and a purified air guide tube 3 equipped with an air purification component 4 (the tube for balancing the internal and external pressure of the infusion bottle, commonly known as an exhaust tube). The side hole needle 1 can also be directly set to the top of the dropping funnel together with the purified air duct 3 to form the liquid inlet interface. Even if an infusion bag is used for infusion, a purified airway tube 3 should be inserted to minimize stagnation and residual fluid. The transfusion tube that is equipped with drip speed regulator 10 is made of customary transfusion catheter 11 and short section elastic tube 14 (its effect is: 1. when venipuncture is pinched and squeezed it can bounce back and can impel blood return to confirm whether the puncture is successful; 2. can be pulled out by positive pressure Needle, that is, pull out the needle while pinchi...

Embodiment 2

[0056] like Figure 4 As shown, its liquid inlet interface 20 is equipped with a bottle connector 22 of a purification type air guide port 21 (commonly known as an exhaust port) and a dropper equipped with a drip speed regulator 10 and marked with a scale that is provided with a suspension 19. The burette 23 constitutes. The drip speed regulator 10 is used to control the liquid extraction volume. A liquid medicine filter 29 is provided at the bottom of the dropping funnel 28 . Dripper (micro-drop dripper) 27 is used for children's infusion. The float valve 25 is located above the dripper 27 . The tentacles-like limiter 24 on the spool can prevent the liquid path from being blocked on the spool. The closed air guide mechanism is an upper controllable bypass air guide tube 26 that is arranged on the liquid outlet of the float valve and the side wall of the float valve and is equipped with a switch 17 (slider) that can be pre-opened and closed by the nurse. When continuing t...

Embodiment 3

[0058] like Image 6 As shown, its liquid inlet interface is composed of two bottle-inserting connectors 40 and a dropper 41 (Y-shaped infusion catheter equipped with a drip rate regulator 10), which is used by tall nurses to adjust the drip rate, liquid conversion and anti-residual liquid control . The liquid medicine filter 34 is provided on the infusion tube 50 provided with the grafting interface 49 . The difference between the cap button type connector 47 and the movable cap button type connector 32 is that the cap button of the cap button type connector cannot slide up and down along the outer wall of the liquid inlet of the nipple connector. The float valve is located above the dripper 5 . The closed air guide mechanism is an upper pre-opening float valve, which is composed of a deformable float valve shell (made of medical flexible material that can be bent and deformed) and a valve core. The valve core is composed of a sleeve 44 with a liquid guide hole 43 and a fl...

Abstract

The invention discloses a disposable automatic flowing stopping type liquid residual prevention infusion apparatus. The disposable automatic flowing stopping type liquid residual prevention infusion apparatus is composed of a liquid inlet connector, a drip chamber, a floating valve, an infusion pipe, a dripping speed regulator, a liquid medicine filter, a liquid outlet connector, a closed type air guiding mechanism, a hand-operated pressurization pump and a gallbladder-like bottle rinsing dripping-in device, wherein the closed type air guiding mechanism is additionally arranged on a liquid route above an infusion pipe and can guide purified air which comes from an infusion bottle into an infusion pipe cavity from top to bottom at the end of the infusion on that day, the hand-operated pressurization pump is additionally arranged on the infusion pipe, and the gallbladder-like bottle rinsing dripping-in device is additionally arranged on the liquid inlet connector. The disposable automatic flowing stopping type liquid residual prevention infusion apparatus is characterized in that flowing can be automatically stopped after the previous infusion bottle stops dripping; blood coagulation and liquid route blocking possibly caused by blood return in an infusion needle can be avoided; the closed type air guiding mechanism can be opened in advance and closed freely by a nurse and is safe, flexible and convenient to use, precious residual liquid in the infusion bottle and the infusion pipe can be completely infused into a human body, waste can be avoided, and the curative effect can be ensured; pressurization can be conducted so that rapid infusion can be conducted to rescue a patient; blood exposure accidents can also be avoided even when the patient faints in a toilet along with the infusion bottle. The disposable automatic flowing stopping type liquid residual prevention infusion apparatus is used for conducting clinical continuous infusion and preventing residual liquid.

Description

technical field [0001] The invention relates to a disposable infusion set for medical use, in particular to a disposable automatic flow-stopping anti-liquid residue type infusion set. Background technique [0002] 1. Phenomena and causes of liquid medicine waste [0003] (1) During the infusion process, the exhaust, liquid discharge and refilling phenomenon after the infusion tube enters the air, the previous infusion bottle stops dripping and is not discovered by the patient in time, and the air will enter the Murphy's dropper [note: the present invention will use it (Such as: the customary straight tube-shaped Mufei's dropper, the Mufei's dropper with a grafted dosing interface, the cone-shaped Mufei's dropper, etc.) is referred to as the dropping funnel. The bottle-inserting connector and the bottle-inserting needle (which includes side hole needles, beveled needles, and air guide tubes equipped with air purification parts, etc.) are collectively referred to as bottle co...
