Description

A bubble-eliminating drip bucket for an infusion tube

Technical Field

The utility model relates to the technical field of medical equipment, in particular to a bubble-eliminating drip funnel for an infusion tube.

Background technique

Infusion sets are a common medical consumable. After sterilization, a channel between the vein and the drug solution is established for intravenous infusion. Disposable infusion sets are mainly composed of bottle stopper puncture devices, air filtration devices, hoses, drip buckets, flow regulators, drug filter and intravenous infusion needles. During infusion, if the drug solution is finished, the blood will flow back. It is dangerous not to exhaust when changing the bottle, but it is very troublesome to exhaust the air. Some infusion sets are equipped with various styles of self-closing valves at the drip bucket. Although they can automatically close to preserve the liquid after the drug solution is finished, it is difficult to open the valve when changing the bottle, and the operation is troublesome.

During the use of the existing infusion set, air and liquid medicine coexist in the drip bucket, the air in the hose will flow along with the liquid medicine, and the liquid medicine will be transported along with the bubbles when it flows out from the infusion set terminal, which will have an adverse effect on the patient's infusion. It is urgently needed to improve and perfect the drip bucket for the infusion set. Therefore, a drip bucket for an infusion tube with bubble elimination is provided.

Detailed ways

The utility model is further described in detail below through the drawings and embodiments.

The embodiment of the utility model provides a drip bucket for an infusion tube with bubble elimination, as shown in Figures 1-4, comprising a drip bucket 1, a liquid inlet hose 2 is fixedly installed on the top of the drip bucket 1, a liquid outlet hose 3 is fixedly installed on the bottom of the drip bucket 1, the liquid inlet hose 2 passes through the top of the drip bucket 1, the liquid outlet hose 3 passes through the bottom of the drip bucket 1, a spacer 9 is fixedly installed on the inner side of the drip bucket 1, a dropper 10 is fixedly installed on the bottom of the spacer 9, and through the setting of 9, a degassing head 11 is fixedly installed inside the drip bucket 1, a connecting cavity 12 is opened inside the degassing head 11, the bottom of the degassing head 11 is fixedly connected to the top of the liquid outlet hose 3, and the inside of the drip bucket 1 The parts are respectively provided with a drip chamber 7 and a liquid storage chamber 8. Through the arrangement of the degassing head 11 and the connecting chamber 12, the medicinal liquid can enter the liquid storage chamber 8, so that the connecting chamber 12 and the liquid storage chamber 8 form a communicating vessel, and the air in the liquid storage chamber 8 is blocked by the medicinal liquid, so that the bubbles are isolated on the outside of the connecting chamber 12, and the bubbles are prevented from entering the liquid outlet hose 3. When the medicinal liquid flows out from the infusion terminal, there will be no bubbles in the liquid outlet hose 3 below the drip bucket 1, and the bubbles are eliminated on the outside of the connecting chamber 12, which effectively solves the problem of bubbles being transported to the human body along with the medicinal liquid, so that the patient can receive normal infusion treatment.

Specifically, a vent pipe 4 is fixedly installed on the top of the drip bucket 1, a vent head 5 is fixedly installed on the top of the vent pipe 4, and a filter layer 6 is fixedly installed on the inner side of the vent head 5; the vent pipe 4 runs through the top of the drip bucket 1, and the vent pipe 4 is located on the right side of the liquid inlet hose 2, and the bottom end of the vent pipe 4 is located below the partition 9. Through the coordinated use of the vent pipe 4, the vent head 5 and the filter layer 6, the air is filtered through the filter layer 6, thereby effectively blocking bacterial infection, improving the safety and sterility of the infusion process, and the whole structure is simple and reliable.

The dripping chamber 7 is located above the diaphragm 9, and the liquid storage chamber 8 is located below the diaphragm 9; the bottom of the liquid inlet hose 2 is located inside the dripping chamber 7, and the degassing head 11 is located inside the liquid storage chamber 8; the connecting chamber 12 is an "m"-shaped structure, and the liquid outlet hose 3 is connected to the connecting chamber 12. The communicating vessel formed by the connecting chamber 12 and the liquid storage chamber 8 can allow the medicine at the bottom of the liquid storage chamber 8 to cover the bottom of the degassing head 11 before entering the connecting chamber 12. As the medicine rises in the liquid storage chamber 8, the medicine in the connecting chamber 12 also rises, and finally the medicine fills the entire connecting chamber 12 and is output through the liquid outlet hose 3, isolating the bubbles in the liquid storage chamber 8, and effectively preventing the bubbles from being transported together with the medicine.

Working principle: When in use, when the medicine in the liquid inlet hose 2 is transported to the dripping cavity 7, it is transported to the liquid storage cavity 8 through the dripping tube 10 and connected to the outside world through the ventilation tube 4, which can ensure the dripping of the medicine at the dripping tube 10. Then, when the medicine is flush with the bottom of the connecting cavity 12, as the medicine continues to drip, the bubbles on the surface of the medicine will continue to float on the surface of the medicine as the medicine increases. According to the connecting vessel principle, the medicine can enter the connecting cavity 12. As the medicine gradually submerges the degassing head 11, the medicine can fill the entire connecting cavity 12, and the medicine in the connecting cavity 12 is transported to the liquid outlet hose 3, and the bubbles in the liquid storage cavity 8 are blocked outside, so that the liquid outlet hose 3 can transport the bubble-free medicine to the patient's body for better treatment.
