Description

Closed device for whole-course infusion of tumor chemotherapy drugs

Technical Field

The utility model belongs to the technical field of medical equipment, specifically a whole infusion closed device of tumour chemotherapy medicine.

Background

The chemotherapy drugs often form aerosol or aerosol which can not be seen by naked eyes when in use, and easily enter human bodies through skins and respiratory tracts in the process of drug preparation. Chemotherapy drugs are intensively prepared by a static preparation center at present, and a special preparation room and a biological safety cabinet are arranged, so that the risk of occupational exposure caused by a nurse preparation link is reduced.

The most common chemotherapy drugs are that the drug leakage happens when the infusion tube is replaced, so that the drugs can directly contaminate skin, mucous membrane and the like. Causing local symptoms such as redness, swelling, heat, pain, blisters and eye discomfort, and severely can lead to local tissue necrosis.

At present, more and more chemical drugs are related to tumor treatment, and besides the application of chemotherapy drugs, the occupational safety protection is more important for oncology nurses. Therefore, a closed device for the whole course of chemotherapy drug infusion is needed, which avoids the repeated replacement of the liquid bag, so as to reduce and reduce the harm caused by the overflow of the chemotherapy drug.

SUMMERY OF THE UTILITY MODEL

For solving the problem that exists among the background art, the utility model provides a closed device is infused to whole journey of tumour chemotherapy medicine.

The purpose is achieved, the utility model adopts the following technical proposal: a closed device for the whole course infusion of tumor chemotherapy drugs comprises a drug feeding mechanism I, a plurality of integrated tubes, a plurality of closed mechanisms, a puncture head and a plurality of connecting tubes;

the integrated pipes are arranged from top to bottom, the integrated pipes are identical in structure, each combined pipe consists of a main pipe and a tail pipe communicated with the lower end of the main pipe, two cavities are formed in the upper end of the main pipe, and the lower ends of the two cavities are connected with each other

The two cavities are respectively a cavity I and a cavity II;

the medicine feeding mechanism comprises a medicine feeding mechanism, a sealing mechanism, a tail pipe and a first integrated pipe, wherein the lower end of the medicine feeding mechanism is tightly connected and communicated with the first integrated pipe cavity, the second integrated pipe cavity is fixedly connected and communicated with the sealing mechanism, the tail pipe of the integrated pipe located at the top is tightly connected and communicated with the first integrated pipe cavity through a connecting pipe, the tail pipes of every two adjacent integrated pipes of all the remaining integrated pipes except the integrated pipe located at the top are tightly connected and communicated through connecting pipes, and the tail pipe of the integrated pipe located at the bottom is fixedly connected with a puncture head.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model is designed for the patients with the intravenous chemotherapy drugs, and the quantity of the closed mechanisms can be selected according to the needs, so that the patients can be infused with single or multiple chemotherapy drugs. Because the particularity of the chemotherapy drugs cannot be infused simultaneously, the design characteristic of a plurality of independent pipelines (connecting pipes) is adopted.

The utility model is more suitable for clinical nursing work in the aspects of practicability and safety, and reduces the liquid medicine loss and pollution in the infusion process to the utmost extent. The medicine taking safety of nurses and patients is protected.
