Description

IV push drug infusion set

technical field

The utility model relates to the technical field of medical equipment, in particular to an intravenous injection drug transfusion device.

Background technique

Generally, when using the disposable infusion set for intravenous injection of drugs, the infusion set and the scalp needle junction can only be separated, and then the syringe is connected to the scalp needle after separation, which not only increases the chance of pollution, but also inevitably makes the air The air bubbles enter the scalp needle and are pushed into the patient's blood vessels. After the injection of the drug is separated, the chance of pollution and air entry is increased, and the workload of the nurse is also increased. Moreover, the length between the filter of the traditional infusion set and the scalp needle is mostly about 15 cm, and the connection between the infusion set and the scalp needle is within this 15 cm, and the statically pushed medicine cannot be filtered by the upstream filter. Some particles are injected into the body and may cause infusion reactions.

Contents of the invention

The technical task of the utility model is to solve the deficiencies of the prior art and provide a drug infusion set for intravenous injection.

The technical scheme of the present utility model is realized in the following manner, the structure of the intravenous drug infusion set includes an infusion tube and an intravenous injection needle,

The downstream end of the infusion tube is provided with an intravenous injection needle,

An infusion filter is arranged on the tube of the infusion tube 5-6 cm upstream of the intravenous injection needle;

The infusion tube upstream of the infusion filter is provided with a three-way switch;

The three-way switch is provided with a straight pipe part and a branch pipe part, and the branch pipe part is perpendicular to the straight pipe part and communicates with the straight pipe part;

The straight pipe at the intersection is provided with a valve body, and the valve body is provided with a three-way valve spool;

The spool of the three-way valve is provided with a straight channel and a branch channel; the branch channel is arranged on one side of the straight channel, and the branch channel and the straight channel are vertically connected;

The straight passage of the three-way valve spool and the straight pipe of the three-way switch are coaxially arranged;

The branch channel of the three-way valve spool and the branch pipe of the three-way switch are coaxially arranged;

The three-way valve spool is connected with a valve handle, and the rotation of the valve handle drives the three-way valve spool to rotate in the valve body to switch the passage of the valve body;

The branch pipe part of the three-way switch is connected with an intravenous injection branch injection tube, and a branch pipe joint is arranged on the intravenous injection branch injection tube; a branch pipe cap is arranged on the branch pipe joint.

The branch pipe cap is threadedly connected with the outer periphery of the branch pipe joint.

An infusion drip pot is arranged on the infusion tube upstream of the three-way switch.

The upstream end of the infusion tube is provided with a liquid inlet needle.

Compared with the prior art, the utility model has the following beneficial effects:

The intravenous injection drug infusion set is placed in the upstream section of the infusion filter for the intravenous injection branch injection tube, regardless of the intravenous infusion and the intravenous injection, the drug solution can be finally filtered through the infusion filter to remove impurities. Effectively guarantee the safety of the liquid medicine.

Before pushing the drug statically, switch the three-way switch to the state of the upstream straight tube and the branch tube, fill the upstream drug solution into the branch tube and overflow at the branch tube joint, the purpose is to exhaust, After the branch pipe is filled with liquid medicine, switch the three-way switch to the state of the branch pipe and the downstream straight pipe, and connect the static push injection tube of physiological saline or glucose injection to the branch pipe joint for pre-push. Note, the purpose is to push the drug solution in the infusion tube into the patient's vein in advance, flush the tube with normal saline or glucose injection, so as to avoid the chemical reaction between the drug pushed after the injection and the previous drug; after flushing the tube, insert the static push syringe , carry out static push to the patient, at this time, the upstream infusion is closed under the action of the three-way switch, which will not affect the static push; after the static push, the tube can be flushed again, and then switch the three-way switch to the original infusion state to resume the infusion.

There is no need to separate the scalp needle, and the medicine can also be filtered through the medicine filter to reduce medicine pollution and air entry. And even if the patient is punctured with a disposable needle, re-puncture can be avoided to cause greater pain to the patient.

Putting a branch pipe cap on the branch pipe joint end can keep the nozzle end hygienic and clean.

The drug infusion device for intravenous push injection has reasonable design, simple structure, safety and reliability, convenient use and easy maintenance, and has good popularization and use value.
