Embodiment 1

[0035] Such as Figure 1~2 As shown, a structure-improved anti-bubble rapid exhaust infusion set of this embodiment includes a drip funnel 1, the upper end of the drip funnel 1 is connected to the upper drip tube 2, and the lower end of the drip funnel 1 It is connected with the lower dripping pipe 3, and also includes an air insulation cover 4, and the air insulation cover 4 cooperates with the lower dripping pipe 3, and the air insulation cover 4 or the lower dripping pipe 3 is provided with Make the liquid flow into the anti-bubble liquid tank 5 of the lower dropper 3 from bottom to top.

[0036] Specifically, the air insulation cover 4 in this embodiment is provided with an anti-bubble outlet tank 5 that allows liquid to flow into the lower drip tube 3 from bottom to top.

[0037] The working principle of the present invention: during infusion, the liquid drips from the upper dripping tube 2, the dripping liquid will not immediately enter the lower dripping tube 3, and th...

Embodiment 2

[0043] Such as image 3 As shown, the difference between this embodiment and Embodiment 1 is that: the inner side of the air insulation cover 4 in this embodiment is provided with a groove 8, and the lower dripping tube 3 is provided with a step 9, and the groove 8 cooperates with said step 9. When the present embodiment is in working condition, the air-insulating cover 4 is inverted and covers the outer wall of the lower dripping tube 3, and the air-insulating cover 4 and the lower dripping tube 3 are connected through the groove 8 and the step 9, and the connection is tight. More effectively isolate the air entering the lower dripping pipe 3 to prevent the generation of air bubbles.

[0044] The step 9 is set in the middle of the lower drip tube 3, and the step 9 protrudes outward along the outer wall of the lower drip tube 3, and the step 9 passes through the outlet of the lower end of the dropping funnel 1, and 1 / 2 of the step 9 is set in the dropping funnel 1 , the othe...

Embodiment 3

[0047] Such as Figure 4 As shown, the difference between this embodiment and Embodiment 1 is that the lower dripping pipe 3 described in this embodiment is provided with an anti-bubble outlet tank 5 that allows the liquid to flow into the lower dripping pipe 3 from bottom to top.

[0048] Wherein, the inner side of the air insulation cover 4 is provided with a groove 8, and the lower dropper 3 is provided with a step 9, and the groove 8 cooperates with the step 9. The step 9 is provided with an anti-bubble outlet tank 5 that allows the liquid to flow from bottom to top into the lower drip tube 3, and the lower edge of the air insulation cover 4 is higher than the bottom edge of the anti-bubble outlet tank 5. lower edge. When this embodiment is in working condition, the air insulation cover 4 is inverted and covered on the outer wall of the step 9, 1 / 2 of the step 9 is set inside the dropping funnel 1, and the other 1 / 2 is set outside the dropping funnel 1 to prevent air bubb...

Abstract

The invention belongs to the technical field of medical transfusion devices and particularly relates to a bubble-prevention fast exhaust transfusion device with an improved structure, which comprises a dripping chamber, wherein the upper end part of the dripping chamber is connected with an upper liquid dripping pipe, the lower end part of the dripping chamber is connected with the lower liquid dripping pipe, the bubble-prevention fast exhaust transfusion device also comprises an air isolation cover body, the air isolation cover body is matched with the lower liquid dripping pipe, and the airisolation cover body or the lower liquid dripping pipe is provided with a bubble-prevention liquid outlet groove for making liquid flow into the lower liquid dripping pipe from bottom to top. The bubble-prevention fast exhaust transfusion device has the advantages that the structure is simple, the production cost is low, the goal of automatically, fast and thoroughly exhausting the air in the transfusion device can be realized, the exhaust operation by medical personnel is not needed, the exhaust speed is high, and safety and reliability are realized.

Description

technical field [0001] The invention belongs to the technical field of medical infusion sets, in particular to a structure-improved anti-bubble rapid exhaust infusion set. Background technique [0002] The infusion set is a kind of medical device that is often used in the treatment of diseases, and it is necessary to use the infusion set when infusing the patient. At present, the common infusion set commonly used in the medical field is made up of insertion needle, air inlet pipe, upper infusion tube, dropping funnel, lower infusion tube, regulating switch, filter and venous needle. Ordinary infusion set, at the beginning of the infusion, when the liquid medicine enters the dripping funnel, due to the dual influence of gravity and pressure on the liquid medicine, it is very easy to form a gas-liquid mixture of gas and liquid medicine, and the gas-liquid mixture will quickly enter the bottom of the dripping funnel at the same time. In the infusion catheter, air bubbles are f...
