Needle-less infusion instrument

Abstract

The invention discloses a needle-less infusion instrument which comprises a main body and an infusion bag, wherein the infusion bag is arranged at the top of the main body; a suspending hole is formed at the top end of the infusion bag; a first joint is arranged at the bottom of the infusion bag; a second joint is arranged on one side of the first joint; the first joint and the second joint are arranged in parallel; a screw cap is arranged at the bottom of the first joint; a threaded part is arranged at the bottom of the screw cap; the screw cap is in threaded connection with the threaded part; an infusion clip is arranged at the bottom of the threaded part; an infusion instrument is arranged at the bottom of the infusion clip; and the threaded part, the infusion clip and the infusion instrument are connected with each other through catheters. According to the invention, the screw cap and the threaded part are arranged in threaded connection with each other, so that the infusion instrument need not be replaced even if the upper part of the infusion instrument falls off in the infusion process of the patient, the saving of resource and infusion time is benefited, and meanwhile, the infusion clip is arranged, so that the liquid flow rate in the infusion process can be controlled according to the specific condition, the infusion can be stopped at any time if necessary and the increasing of the infusion efficiency is increased.

Description

technical field [0001] The invention belongs to the medical and health field, and in particular relates to a needle-free infusion set. Background technique [0002] In medical clinics, intravenous infusion is the most common method in the process of treating patients. However, during the infusion process of the existing medical staff to the patient, one of the two ports of the infusion bag is connected to the infusion set, and the other port is convenient for adding medicine. , the lower end of the infusion set is completed by puncturing the heparin cap of the indwelling needle with a scalp steel needle or directly puncturing the skin. In addition, the puncture needle may easily cause needle-stick injuries, and the needle touching the patient's blood may cause infection of AIDS, hepatitis and other diseases. Medical personnel bring unnecessary pain. In addition, many patients press the pipeline under the body during infusion, and the top of the infusion set falls off as soo...

However, during the infusion process of the existing medical staff to the patient, one of the two ports of the infusion bag is connected to the infusion set, and the other port is convenient for adding medicine. , the lower end of the infusion set is completed by puncturing the heparin cap of the indwelling needle with a scalp steel needle or directly puncturing the skin. In addition, the puncture needle may easily cause needle-stick injuries, and the needle touching the patient's blood may cause infection of AIDS, hepatitis and other diseases. Medical personnel bring unnecessary pain. In addition, many patients press the pipeline under the body during infusion, and the top of the infusion set falls off as soon as they turn over. In this way, the infusion set must be replaced, which increases the troubles of patients during infusion. Therefore, the invention It is necessary for a needle-free infusion set to solve the above problems
