Description

Anti-bubble infusion set

Technical field

The utility model relates to the technical field of medical devices, specifically an anti-bubble infusion set.

Background technique

The infusion set is a common medical consumable. After sterile treatment, it establishes a channel between the vein and the medical solution and is used for intravenous infusion. The disposable infusion set mainly consists of a cork puncture device, an air filter device, a hose, a dripper, a flow regulator, a medicinal solution filter and an intravenous infusion needle. During infusion, if the blood will flow back after the medicinal solution is infused, It is dangerous not to vent the air when changing bottles, but it is very troublesome to vent the air completely. Some infusion sets are equipped with various styles of self-closing valves at the mouth of the dripper. Although they can automatically close and retain the liquid after the liquid is infused, it is difficult to change the bottle and open the valve, making the operation troublesome.

During the use of the existing infusion set, when there is air in the dripper, the air will flow along with the medicinal solution in the hose. When the medicinal solution flows out from the terminal of the infusion set, it will be transported along with the bubbles, which will cause problems to the patient. Adverse effects require urgent improvement and improvement of the infusion set.

Detailed ways

The utility model will be further described in detail below through the drawings and examples.

The embodiment of the present utility model provides an anti-bubble infusion set, as shown in Figures 1-3, including a dripping hopper 1, a liquid inlet pipe 2 is fixedly installed on the top of the dripping hopper 1, and a liquid outlet pipe is fixedly installed on the bottom of the dripping hopper 1 3. The inside of the dripping hopper 1 is provided with a liquid inlet chamber 14, a left cavity 15 and a right cavity 16. A partition 7 is fixedly installed on the inside of the dripping hopper 1, and a baffle 9 is fixedly installed at the bottom of the partition 7. The dripping hopper A fixed base 10 is fixedly installed on the inner bottom wall of 1. A communication groove 11 is provided on the inside of the fixed base 10. A connecting elbow 13 is fixedly installed at the top of the liquid outlet pipe 3. The connecting elbow 13 is fixedly connected and connected with the communication groove 11. A precision filter membrane 12 is installed at one end of the communication groove 11 away from the connecting elbow 13, and a funnel 8 is fixedly installed at the bottom of the partition 7. The liquid is dripped into the liquid inlet chamber 14 through the liquid inlet pipe 2, and passes through the funnel 8. 8 drops into the left cavity 15, and through the barrier of the baffle 9, when the medical liquid contacts the bottom of the baffle 9, the medical liquid flows from the inner box of the left cavity 15 to the right cavity 16, so that the medical liquid First, it passes through the connecting groove 11. When the liquid in the left cavity 15 gradually rises, the liquid in the right cavity 16 rises together. When the liquid does not pass through the top of the connecting elbow 13, the liquid in the right cavity 16 rises. The medicinal liquid is transported into the connecting elbow 13 through the connecting groove 11, so that the air in the inner cavity of the dripper 1 is blocked by the medicinal liquid, effectively preventing air bubbles from entering the hose, and finally all the medicinal liquid discharged into the hose through the liquid outlet pipe 3 There will be no bubbles, so as to achieve the anti-bubble effect. An air filter device is provided inside the drip hopper 1.

Specifically, the funnel 8 is located in the left cavity 15. The liquid inlet chamber 14 is connected to the left cavity 15 through the funnel 8. The funnel 8 is located on the left side of the baffle 9; the baffle 9 is located in the left cavity 15. There is a gap between the bottom of the baffle 9 and the inner bottom wall of the dripper 1 between the left cavity 15 and the right cavity 16; the connecting elbow 13 is located inside the right cavity 16, and the connecting elbow 13 is located inside the right cavity 16. The tube 13 is located on the right side of the baffle 9. Through the arrangement of the left cavity 15 and the right cavity 16 as well as the communication groove 11 and the connecting elbow 13, the left cavity 15 and the breathable and waterproof membrane 6 can be separated by the baffle 9. To realize the principle of the connector, the baffle 9 can keep the liquid level in the left cavity 15 and the right cavity 16 flush, and when the liquid rises, the liquid is transported to the connecting bend through the communication groove 11. In the tube 13, the air in the drip funnel 1 is cut off by the medical liquid, so that the medical liquid can be better transported through the liquid outlet pipe 3 without the inclusion of air bubbles, thereby reducing the adverse effects on the patient during infusion.

The air filtration device includes a breather tube 4, which is fixedly installed with the drip bucket 1. A breathable waterproof membrane 6 is installed on the top of the breather tube 4, and a top cover 5 is fixedly connected to the top of the breather tube 4. The breathable waterproof film 6 passes through the top cover. 5 is fixedly installed with the vent pipe 4; the vent pipe 4 penetrates the partition 7 and is connected with the right cavity 16. The top cover 5 and the breathable and waterproof membrane 6 are located above the drip bucket 1. Through the vent pipe 4 and the top cover 5 and the breathable and waterproof membrane The arrangement of the membrane 6 can connect the dripping hopper 1 with the outside air, making it easier for the medicinal solution to enter the dripping hopper 1. In conjunction with the arrangement of the breathable and waterproof membrane 6, the air can be better filtered and the safety of the infusion can be increased.

Among them, the precision filtration membrane 12 can completely filter the impurities in the medicinal liquid. The precision filtration membrane 12 is hydrophilic. When it comes into contact with the medicinal liquid, the micropores on the precision filtration membrane 12 will open and the medicinal liquid will flow down. This is especially suitable for The Chinese medicine liquid filters impurities; the breathable and waterproof membrane 6 can allow air to enter and exit, blocking the outflow of the liquid medicine. Both the precision filter membrane 12 and the breathable and waterproof membrane 6 are ordinary filter membranes with low price and low cost.

Working principle: During use, when the medicine bottle is connected for infusion, the air pressure in the dripper 1 can be balanced through the vent pipe 4 and the breathable waterproof membrane 6, which facilitates the input of the liquid in the liquid inlet pipe 2 and enters the liquid inlet chamber 14. The medicinal liquid is transported into the left cavity 15 through the funnel 8. The medicinal liquid in the left cavity 15 and the right cavity 16 will automatically rise. Then, the medicinal liquid will filter impurities through the precision filter membrane 12. When the medicinal liquid rises, When it exceeds the connecting elbow 13, the medicinal liquid in the right cavity 16 is transported to the liquid outlet pipe 3 through the connecting groove 11 and the connecting elbow 13, and the medicinal liquid in the left cavity 15 and the right cavity 16 passes through the connecting groove 11 and the connecting elbow 13. The air in the dripping hopper 1 is cut off so that the liquid medicine entering the communication groove 11 and the connecting elbow 13 does not contain bubbles, so that the medicine liquid in the conveyor hose passing through the liquid outlet pipe 3 does not have bubbles. It can prevent bubbles.
