Embodiment 1

[0046] In this example, if figure 1 As shown, an injection system includes an injection assembly 1, and the injection assembly 1 includes one or more injection needles 11, an injection tube 12, and a diagnostic tube 13, and an injection tube 12 and the diagnostic tube 13 are provided There is a detachable connection structure.

[0047] In this example, if figure 1 and Figure 4a~4b As shown, the injection needle 11 is arranged in the distal area of ​​the injection tube 12 or the diagnostic tube 13; the proximal area of ​​the injection tube 12 and the proximal area of ​​the diagnostic tube 13 are at any specified loading position A sealed connection structure 2 is formed, and the sealed connection structure 2 is the detachable connection structure. The sealed connection structure 2 allows the diagnostic tube 13 to be replaced repeatedly, so that the injection 121 can be continuously injection.

[0048] In this example, if Figure 4a~4b As shown, the sealed connection struc...

Abstract

The invention relates to the field of medical instruments, in particular to an injection system which comprises an injection assembly, the injection assembly comprises one or more injection needles, an injection tube and a diagnosis tube, and a detachable connecting structure is arranged between the injection tube and the diagnosis tube; the injection tube accommodates an injection, and the diagnosis tube accommodates an intervention medium; wherein after the injection tube injects the injection substance, part of the injection substance is injected into the target tissue, and the rest of the injection substance is injected into the target tissue through the intervention medium. According to the injection system, the injection tube and the diagnosis tube can be synchronously pushed, synchronously static and synchronously moved, sealing and locking reversibility of the injection tube and the diagnosis tube can be achieved, the injection tube and the diagnosis tube can be freely adjusted according to needs, and after other injection objects are injected into target tissue by an intervention medium, the diagnosis tube can be repeatedly replaced for multiple times; multiple times of continuous injection of an injection object at a target tissue is ensured, and the injection efficiency is improved.

Description

[0001] The applicant's prior application number is 202110791104.9, and the application date is July 13, 2021. All the contents of the prior application are hereby taken as a reference. technical field [0002] The invention belongs to the field of medical equipment, and in particular relates to an injection system. Background technique [0003] At present, the morbidity and mortality of heart failure are relatively high, and it is an important cause of death for most patients with cardiovascular diseases. There are nearly 23 million people in the world suffering from this disease. The full name of heart failure is heart failure, which means that due to the dysfunction of the systolic or diastolic function of the heart, the venous return blood cannot be fully excreted from the body, resulting in blood stasis in the venous system and insufficient blood supply in the arterial system, which eventually leads to cardiac circulatory system disorders. The development process of hear...
