Description

Special infusion set for chemotherapy

technical field

The invention belongs to the field of medical equipment, in particular to an infusion set specially used for chemotherapeutic drugs.

Background technique

Chemotherapy is the abbreviation of chemical drug therapy. It is a treatment method that uses chemical drugs to prevent the proliferation, invasion, and metastasis of cancer cells, and finally kill cancer cells. It is a systemic treatment method, together with surgery and radiotherapy, and is called the three major treatment methods for cancer.

Chemotherapy drugs are cytotoxic drugs and have toxic effects on the human body. Medical personnel need to take protection when using chemotherapy drugs. At present, the infusion set for clinical chemotherapy is a disposable precision infusion set, which can prevent chemotherapy particles for patients, but lacks protection for nurses. When a nurse is administering medicine, when the infusion set is inserted into or pulled out of the infusion bag, it is easy for the chemotherapy drug to overflow, and it is easy to contaminate the nurse, the patient's clothing and the surrounding environment.

Chinese patent CN201120036462.0 discloses a chemotherapy infusion set, including a plastic needle, an infusion tube, a Murphy dropper, a flow control switch, and a puncture needle. The on-off valve is provided with a negative pressure bag.

Chinese patent CN200920290582.6 discloses a chemotherapy infusion set, including a cork piercer, an infusion tube, a burette, and a needle. A protection plate is fixedly installed on the piercing needle of the cork piercer, and a baffle is arranged on the edge of the protection plate. The diameter of the protective disc is larger than that of the bottle stopper, a hand rest is arranged under the protective disc, and anti-slip protrusions are arranged on the surface of the hand rest.

However, the existing chemotherapy infusion sets cannot solve the problem that chemotherapy drugs overflow easily when the infusion bag is inserted.

Utility model content

The purpose of this utility model is to provide a special infusion set for chemotherapy aiming at the defects of the prior art.

In order to achieve the above object, the utility model adopts the following technical scheme: a special infusion set for chemotherapy, comprising: a double-headed infusion set and a chemotherapy infusion joint, wherein the double-headed infusion set includes a venous needle, a lower infusion tube, an upper An infusion hose, a filter, a flow rate regulator, a drip pot and a Y-shaped tee, and the two ends of the tee are respectively connected to the first puncturer and the internal thread joint through the hose; the chemotherapy infusion connector includes the second puncturer and the The needle infusion joint is sealed and connected as a whole, and the end of the needleless infusion joint has an external thread structure; the internal thread joint and the external thread structure are spirally connected.

Liquid-stop clips are respectively arranged on the flexible tubes connecting both ends of the Y-shaped tee to the piercer and the internal thread joint.

A protective sleeve is provided outside the external thread structure of the needle-free infusion connector.

The internal thread joint and external thread structure are made of PC or PE material.

When in use, first use the second puncturer of the chemotherapy infusion connector to insert into the mouth of the chemotherapy drug infusion bag for standby. Since the needle-free infusion connector is in a closed state, it prevents chemotherapy drugs from splashing and causing harm to medical staff and pollution to the environment; there is no needle The outer thread structure of the infusion connector is provided with a protective sleeve, so that the chemotherapy infusion connector is not polluted by environmental bacteria. Clamp the internal thread joint at one end of the Y-shaped tee of the double-ended infusion set with a liquid-stopping clamp, and the first piercer at the other end of the Y-shaped tee penetrates into the mouth of the bag or bottle of the flushing solution for flushing. After flushing, Clamp it with a liquid stop clip. Then remove the outer protective sleeve of the external thread of the needleless infusion connector, connect the internal thread joint at one end of the Y-shaped tee with the external thread, open the liquid stop clip, and perform chemotherapy drug infusion. When the chemotherapeutic drug infusion is completed, clamp the liquid stop clamp under the internal threaded joint on this side, open the other end of the Y-shaped tee joint, and continue to rinse with the flushing fluid to complete the entire chemotherapy process.

The utility model has novel structure and convenient operation, which can effectively prevent the overflow of chemotherapeutic drugs and reduce the psychological pressure of medical staff when administering chemotherapy. At the same time, the single-head infusion set is not convenient for flushing and chemotherapy, and it is convenient for medical staff to perform chemotherapy.
