Embodiment 1

[0022] Embodiment 1: A non-invasive interventional treatment system, including a main body 1, a high-speed nozzle 2, a trachea 3, an air guide seat 4, a connecting seat 5, and an air storage cylinder 6. The main body 1 is provided with a medicine ejection port 11 and a medicine ejection port. 11 Communicating inner cavity 12, the inner cavity 12 is provided with a sonic nozzle 13 close to the drug ejection port 11, the high-speed nozzle 2 is screwed on the drug ejection port 11, and the exit of the sonic nozzle 13 and the inlet of the high-speed nozzle 2 are provided There is a certain distance to form a low-pressure venturi zone 14. The part of the high-speed nozzle 2 close to the drug ejection port 11 is a parallel part 21 of equal inner diameter, and the front part is a horn-shaped diffuser 22. The airway 3 is screwed to the high-speed nozzle 2, the air guide tube 3 is a cylindrical member of equal inner diameter with the same inner diameter as the maximum inner diameter of the...

Embodiment 2

[0023] The second embodiment: the other structure is the same as the first embodiment, the difference is that the bottom of the gas cylinder 6 is provided with a gas supply hole 61, and the disposable high-pressure gas cylinder 8 in the gas cylinder 6 is replaced with a gas cylinder 8', and the gas cylinder 8' An air supply pipe 62 is provided on the air supply hole 61 and communicates with an outer gas cylinder (not shown). The front of the air storage cylinder 8'is provided with an air supply valve 81', and the air supply valve 81' is provided with a valve The control rod 82', the valve control rod 82' passes through the connecting seat 5 and is connected to one end of the pressing handle 10. The high-speed nozzle 2 and the air duct 3 are coaxially sleeved with a muffler 23, and the muffler 23 is screwed to the air duct 4 on.

Embodiment 3

[0024] The third embodiment: the other structure is the same as that of the second embodiment, the difference is that the bullet cartridge 7 arranged in the inner cavity 11 is removed, and the main body 1 is provided with a medicine supply channel 15 and the outlet of the medicine supply channel 15 is arranged at a sonic nozzle At the low-pressure venturi area 14 between the exit of 13 and the entrance of the high-speed nozzle 2, a drug delivery valve 16 is provided at the entrance of the drug supply channel 15, and the drug delivery valve 16 is provided with an external drug box interface, and the external drug box 17 is provided The drug delivery valve 16 communicates with the drug supply channel 15 through the drug delivery valve 16.

Abstract

The invention relates to a non-invasive insert treating system, which comprises a main body arranged with high-pressure gas provider and drug feeder, a drug injector and a chamber through to the drug injector. Wherein, the chamber near the injector has a nozzle; the drug injector is arranged with high-speed injection tube whose front end has guide tube; the nozzle and the high-speed injection tube have drug disperser between them. The invention can fully mix drug and gas, and disperse the high-speed drug gas into atom; and the back of injection tube ha a guide tube to limit the disperse of gas, therefore, the gas has high speed at the injection surface; and the drug can be uniformly distributed, to control the drug radiation area and improve the drug effect.

Description

Technical field [0001] The invention relates to a treatment system, in particular to a non-invasive interventional treatment system. Background technique [0002] Non-contact treatment methods can now be achieved by a variety of needle-free injection devices. The main structure of one of the existing needleless injection devices includes a gas device that drives the drug at a higher pressure, and the drug is driven into the skin of the human body by the instantaneous high-speed gas ejected. For example, the Chinese Invention Patent Application Publication with the application number 95195610.8 published on October 29, 1997 discloses a needle-free parenteral drug delivery device that squeezes the drug through the skin of the patient through a piston or air pressure. The subcutaneous layer does not need to be punctured with an injection needle and has no direct contact with the human body. This is of great significance for reducing cross-infection between patients and reducing the ...
