Disposable oral administration device and administration method

Abstract

The invention discloses a disposable oral administration device and an administration method, and belongs to the technical field of medical instruments. The oral administration device comprises a three-way connecting tube, an oral administration end and a first extension tube. A first connecting port and a second connecting port of the three-way connecting tube are separately connected with a first injector and a second injector. One end of the first extension tube is fixedly connected with the oral administration end to form a whole, and the other end of the first extension tube is detachablyconnected with a third connecting port of the three-way connecting tube. The oral administration end is designed as a cylindrical housing, the first extension tube communicates with the inside of thecylindrical housing, multiple administration holes are evenly distributed on both end surfaces of the cylindrical housing, so that the comfort of use of the oral administration device is improved, and the oral administration device is conveniently washed to reduce residues of radioactive drugs, and can be quickly replaced to avoid radioactive contamination.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a disposable intraoral drug delivery device and a drug delivery method. Background technique [0002] The infusion extension tube is an indispensable tool for medical staff when using micro-injection pumps, and is widely used in clinical practice. The two ends of the traditional extension tube are connected with inner and outer conical joints, and the inner and outer conical joints are mainly suitable for intravenous infusion. When the medical personnel need to use the extension tube to infuse the medicine into the oral cavity of the patient, the external conical joint will cause the patient a heavy foreign body sensation, poor comfort and easy to fall off. If the radioactive residue in the extension tube cannot be rinsed out when the radioactive drug is infused into the patient's oral cavity, it will result in a waste of imaging agents and a large amount of ...

AI Technical Summary

Problems solved by technology

[0004] 1. The drug delivery interface cannot be directly attached to the patient's oral mucosa, and the patient's comfort level is extremely poor during the drug delivery process;

[0005] 2. The dispensing process is uneven, resulting in inaccurate medication and affecting the subsequent image quality;

[0006] 3. The radiopharmaceutical dilution process will increase the radiation exposure time of medical staff;

[0007] 4. It cannot be washed quickly, resulting in the residue of radioactive substances and polluting the environment;

[0008] 5. It cannot be replaced in real time, causing radioactive pollution
