Embodiment 1

[0024] like figure 1 Shown automatic exhaust infusion set, this infusion set comprises bottle stopper puncturer, flow regulating valve, dropping funnel 1, upper infusion hose 2 and lower infusion hose 3 (bottle stopper puncturer and flow regulating valve are existing The structure is not marked in the accompanying drawings), the upper infusion hose 2 communicates with the bottle stopper piercer, the flow regulating valve is arranged on the lower infusion hose 3, and the liquid inlet 7 and the liquid outlet 8 of the dropping funnel 1 are connected to the upper infusion soft tube respectively. The pipe 2 and the lower infusion hose 3 are sleeved with a lower connecting pipe 9 on the liquid outlet 8 of the dropping funnel 1 , and the lower end of the lower connecting pipe 9 is connected to the lower infusion hose 3 . like image 3 As shown, the lower connecting pipe 9 is made of hard plastic, and the upper end of the lower connecting pipe 9 extends upwards to form an exhaust pip...

Embodiment 2

[0027] like Figure 4 The shown automatic exhaust infusion set, the infusion set includes a dripping funnel 1, an upper infusion hose 2 and a lower infusion hose 3, and the liquid inlet 7 and the liquid outlet 8 of the dripping funnel 1 are respectively connected to the upper infusion hose 2 and the lower infusion hose 3. The lower infusion hose 3 and the liquid outlet 8 of the dropping funnel 1 are sleeved with a lower connecting pipe 9 , and the lower end of the lower connecting pipe 9 is connected to the lower infusion hose 3 . The lower connecting pipe 9 is a hard plastic lower connecting pipe 9 whose upper end extends upwards to form an exhaust pipe 10. The exhaust pipe 10 is provided with an axial through hole 12. The upper end of the axial through hole 12 is closed, and the axial through hole 12 is connected with the lower infusion hose 3. The thickness of the peripheral wall of the exhaust pipe 10 is 1.0 mm, and the peripheral wall of the exhaust pipe 10 is uniformly ...

Abstract

The invention relates to a medical apparatus, in particular to an infusion set, which has an automatic exhaust function and comprises a dropping hopper, an upper infusion hose and a lower infusion hose, wherein, a liquid inlet and a liquid outlet of the dropping hopper are respectively communicated with the upper infusion hose and the lower infusion hose; a lower connection tube is sheathed on the liquid outlet of the dropping hopper and the lower end of the lower connection tube is connected with the lower infusion hose while the upper end thereof extends upwards to form an exhaust pipe in which an axial through hole is arranged; the axial through hole is communicated with the lower infusion hose and a liquid guiding clearance which is communicated with the axial through hole is axially arranged at the peripheric walls of the exhaust pipe. The infusion set can effectively solve the technical problem of the occurrence of bubbles in the infusion set and is characterized by simple structure and convenient use. In addition, the infusion set also has wide value in popularization and application.

Description

technical field [0001] The invention relates to a medical device, in particular to an infusion set. Background technique [0002] Existing infusion sets generally include a bottle stopper piercer, a drip funnel and an infusion hose. Bubbles are easily formed in the drip funnel and the infusion hose during use, so the nurse needs to remove the air bubbles, which increases the operating time. Chinese patent (Patent No.: ZL032054599) proposes an anti-bubble infusion device, which will not enter the downcomer when the position of the drip funnel is changed after this infusion device removes excess gas in the drip funnel. Manual exhaust is required. [0003] Chinese invention patent application (application number is 200610146971.2) discloses a kind of auto-exhaust self-destruction type infusion set that is made up of bottle stopper piercer, catheter and dripping funnel, it is characterized in that there is an exhaust pipe in the dripping funnel, its lower end It is connected w...
