Multi-drug injector

Abstract

The invention discloses a multi-drug injector. The multi-drug injector comprises a first needle tube, a second needle tube and a rotating switch. At least three pushing-injecting devices are arrangedin the first needle tube. The rotating switch is arranged between the first needle tube and the second needle tube. The rotating switch is provided with a channel corresponding to one of the pushing-injecting devices, wherein the rotating switch is used for controlling one of the pushing-injecting devices to be opened. The respective pushing-injecting devices can complete suction and injection ofdifferent drugs; normal saline is stored in one of the pushing-injecting devices, tube washing is carried out through the normal saline in two times of drug injection to avoid a drug reaction; by virtue of the arrangement of the rotating switch, only one pushing-injecting device can be started each time for operation, so that influence to other paths caused by one path of drug injection is avoided; and the multi-drug injector is simple in structure and is capable of carrying out muscle or subcutaneous injection with drugs of two or more kinds at the same time, the puncture frequency is reduced, and the pain and psychological stress of a patient are relieved.

Description

Technical field [0001] The invention belongs to the technical field of medical devices, and particularly relates to a multi-medicine injector. Background technique [0002] At present, 5ml, 2ml or 1ml syringes are used for intramuscular injection. When two or more drugs are injected intramuscularly, two or more punctures are required to increase the pain of the patient. Especially for patients in the outpatient infusion room, there are often cases where two or more drugs are injected intramuscularly or subcutaneously at the same time, and multiple intramuscular injections are required when injecting multiple drugs at the same time, which leads to increased pain and swelling in the local puncture point. The incidence of AIDS has increased, and it has caused great psychological pressure on patients. Summary of the invention [0003] To solve the above technical problems, the present invention provides a multi-medicine syringe. [0004] A multi-medicine syringe, comprising a first ne...

Problems solved by technology

[0002] At present, 5ml, 2ml or 1ml syringes are mostly used for intramuscular injection. When injecting two or more drugs into the muscle, two or more punctures are required, which increases the pain of the patient.

Especially for patients in the outpatient infusion room, two or more drugs are often injected intramuscularly or subcutaneously at the same time, while routine injections of multiple drugs at the same time require multiple intramuscular injections, resulting in increased pain for the patient and redness, swelling and induration at the local puncture point The incidence rate increases, and causes great psychological pressure for patients
