Abstract

The present invention provides an automatic intubation drug delivery device for tumor vascular interventional therapy, including a syringe and a fixing frame. A drug filling mechanism is arranged between a pressure plate and a needle tube insertion sleeve. An automatic drug changing mechanism is arranged between a drug bottle and an air pump. When the air pump is started, the gas is introduced into a purifier through a communication tube, and the gas is purified through a filter element, to increase the overall safety and prevent the gas from causing infection to the human body after an air bag is damaged. An infusion tube stops injecting drug when the air bag is driven to expand through the pressure action inside the air pump. When the infusion tube injects drug, the air delivery tube stops the transmission of gas, facilitating the replacement of drug.

Description

DESCRIPTION LU508310
AUTOMATIC INTUBATION DRUG DELIVERY DEVICE FOR TUMOR VASCULAR
INTERVENTIONAL THERAPY AND USAGE METHOD THEREFOR
TECHNICAL FIELD
The present invention relates to the technical field of vascular interventional therapy of tumors, and in particular to an automatic intubation drug delivery device for tumor vascular interventional therapy.
BACKGROUND
In modern society, most patients suffering tumors are treated with surgery, which brings great trauma to patients and the body recovers slowly. However, drugs are implanted into patients through special syringes, thus increasing the patient's recovery speed and reducing the patient's pain.
The traditional syringe is used for injecting the patient manually. Because the manual injection is unstable and requires more for the doctor's operation, it is easy to cause the drug bottle to shake, thus affecting a puncture needle.
In order to solve the aforementioned drawbacks, in the prior art, the Chinese patent with publication number CN211611049U discloses a novel drug delivery device for medical oncology, in which, the air bag can be manually pressed by means of a pressurized anti-shake mechanism, and the generated unstable force can be buffered by an elastic movable ball and a spring, reducing the possibility of shaking or pulling the drug bottle, ensuring the stability of puncture needle insertion, reducing the possibility of bulging and puncture needle falling off, and ensuring the normal supply of drug.
The above-mentioned device uses a pressurized anti-shake mechanism to stabilize the air bag during use. However, although the pressurized anti-shake mechanism can stabilize the air bag, it is cumbersome to manually replace the drug, which increases the workload of medical staff and is prone to increase their fatigue.
