Embodiment 1

[0017] Embodiment 1: A non-invasive interventional treatment system, including a main body 1, a high-speed nozzle 2, an air guide tube 3, an air guide seat 4, a connecting seat 5 and an air storage tank 6, and the main body 1 is provided with a drug ejection port 11 and a drug ejection port 11 communicates with the inner cavity 12, and the inner cavity 12 is provided with a sonic nozzle 13 near the drug ejection port 11, and the high-speed nozzle 2 is screwed on the drug ejection port 11, and the outlet of the sonic nozzle 13 is arranged between the entrance of the high-speed nozzle 2 There is a certain distance to form a low-pressure Venturi zone 14. The part of the high-speed nozzle 2 close to the medicine ejection port 11 is a parallel part 21 of equal inner diameter, and the front part is a horn-shaped diffuser part 22. 2, the air guide tube 3 is a cylindrical member with the same inner diameter as the maximum inner diameter of the diffusion part 22, the air guide seat 4 is...

Embodiment 2

[0018] Embodiment 2: Other structures are the same as Embodiment 1, the difference is that the bottom of the gas storage tank 6 is provided with an air supply hole 61, and the disposable high-pressure gas cylinder 8 in the gas storage tank 6 is replaced by a gas storage cylinder 8', and the gas storage cylinder 8' An air supply pipe 62 is arranged on the top, and the air supply pipe 62 communicates with an external gas cylinder (not shown) through the air supply hole 61. An air supply valve 81' is arranged on the front of the gas storage cylinder 8', and a valve is arranged on the air supply valve 81' 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 pipe 3 are coaxially sleeved with a silencer 23, and the silencer 23 is screwed on the air pipe. 4 on.

Embodiment 3

[0019] Embodiment 3: other structures are the same as Embodiment 2, the difference is that the cartridge case 7 arranged in the inner cavity 11 is removed, and the drug supply channel 15 is set on the main body 1, and the outlet of the drug supply channel 15 is arranged at the sonic nozzle At the low-pressure Venturi area 14 between the outlet of 13 and the entrance of the high-speed nozzle 2, a dosing valve 16 is set at the entrance of the medicine supply channel 15, and the dosing valve 16 is provided with an external medicine box interface, and the external medicine box 17 is set On the dosing valve 16 , it communicates with the medicine supply channel 15 through the dosing 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 are currently available with a variety of needle-free injection devices. Among the existing needle-free injection devices, the main structure of the device includes a gas device that drives the drug at a relatively high pressure, and the drug is driven into the skin of the human body through the instantaneous jet of high-speed gas. Just disclose a needle-free parenteral drug delivery device in the Chinese invention patent application publication number 95195610.8 published on October 29, 1997, which squeezes the drug through the patient's skin through a piston or air pressure and enters it. The subcutaneous layer does not need to be punctured with an injection needle, and has no direct contact with the human body, which is of great significance for reducing cross-infection among patie...
