Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical devices, specifically to an easy-to-operate endoscopic drug delivery tube. Background Technology
[0002] In modern medical technology, endoscopic drug delivery tubes are an important tool for performing minimally invasive surgeries and local treatments.
[0003] Existing endoscopic drug delivery tubes typically employ a single-channel design, which is prone to clogging, especially when delivering viscous or granular drugs. Drug residues can easily adhere to the inner wall of the tube, leading to blockage. Once a blockage occurs, not only does it require frequent flushing, increasing surgical time and costs, but it may also affect the treatment outcome. Utility Model Content
[0004] The problem to be solved by this invention is to provide an easy-to-operate endoscopic drug delivery tube to improve the problems existing in the prior art.
[0005] The technical solution provided by this utility model to solve the above problems is as follows: an easy-to-operate endoscopic drug delivery tube, including a main delivery tube, a drug delivery tube connected to the main delivery tube, a drug delivery bottle connected to the drug delivery tube, and a secondary delivery tube connected to the side wall of the main delivery tube. The secondary delivery tube is used to deliver airflow and flushing liquid, and the secondary delivery tube includes an airflow delivery tube and a liquid delivery tube.
[0006] More preferably, the pneumatic delivery pipe is located below the liquid delivery pipe, and both the pneumatic delivery pipe and the liquid delivery pipe are connected to the main delivery pipe by a one-way valve.
[0007] More preferably, a rubber stopper is connected to the liquid delivery pipe.
[0008] More preferably, a check valve is rotatably connected to the side of the main delivery pipe near the airflow delivery pipe, the check valve being used to prevent the airflow from the airflow delivery pipe from blowing upwards.
[0009] More preferably, the anti-reverse component is circumferentially connected with a rubber strip.
[0010] More preferably, a limiting member is provided inside the main delivery pipe, the limiting member being used to restrict the position of the check valve.
[0011] More preferably, a filter is connected to the gas delivery pipe, the filter being used to filter the gas passing through the gas delivery pipe.
[0012] More preferably, an airbag is connected to the airflow delivery pipe, and a one-way valve is connected to the airbag for air intake.
[0013] Compared with the prior art, the advantages of this utility model are: by setting up an airflow delivery pipe and a liquid delivery pipe, the entire delivery path is divided into a main delivery pipe and a secondary delivery pipe. The main delivery pipe delivers the drug, and the secondary delivery pipe assists in the drug delivery. The liquid delivery pipe can flush the main delivery pipe to prevent blockage and facilitate operation. By setting up a check valve, when the airflow delivery pipe assists in the drug delivery, the drug can be prevented from being blown back by the airflow, thus ensuring the effectiveness of drug delivery.
