Description

Technical Field

[0001] The invention relates to the field of medical auxiliary instruments, in particular to a clinical rapid intravenous infusion device for tumor drugs. Background Art

[0002] Intravenous injection is a method of administration to prevent drug leakage and reduce drug stimulation to the vein wall when using highly irritating drugs. The cell cycle non-specific anti-tumor drugs used in chemotherapy for cancer patients need to be quickly injected intravenously. Usually, the intravenous injection method is first guided by normal saline or 5% to 10% glucose. After the infusion is unobstructed, the infusion tube at the upper end of the Moffitt dropper is clamped with a hemostatic forceps, and then the chemotherapy drugs dissolved in normal saline are injected from the side hole of the Moffitt dropper. If other chemotherapy drugs are used, the hemostatic forceps should be temporarily loosened and the blood vessels should be flushed with normal saline or glucose solution; For example, a clinical intravenous rapid infusion device for tumor drugs disclosed in Chinese patent CN215961516U improves the sealing performance of the branch tube by providing a sealing plug compared with the existing device, so that the branch tube can be sealed by the sealing plug after the drug is injected, preventing bacteria in the air from entering the interior of the infusion tube and causing bacterial infection; However, there are certain defects in this patent. The device clamps the infusion tube by a hemostatic clamp. When the infusion tube is disassembled and replaced, the infusion tube and the position of the hanging bottle are directly separated. At this time, since the hanging bottle contains a lot of physiological saline, a small amount of physiological saline may leak when it is directly separated, further causing material loss and affecting the use of the device by medical staff. At the same time, in winter, the temperature of the liquid medicine is too low during intravenous injection, which will cause physical discomfort to the patient when entering the human body, especially for the weak and seriously ill, which will bring pain and hinder the treatment of the disease. Therefore, it is necessary to provide a clinical intravenous rapid infusion device for tumor drugs to solve the above technical problems. Summary of the invention
