Problems solved by technology

The existing endoscopic surgical treatment of hemostasis is mainly carried out by clamping the wound with hemostatic clips or electrocoagulation, but there are still deficiencies in diffuse venous bleeding and infection prevention and treatment. If the hemostatic and infection prevention drugs can be directly sprayed on the bleeding site, Will help wounds heal and prevent infection
At present, there are few methods of drug administration under endoscopy in China. Amo

Embodiment 2

[0026] Example two, please refer to figure 1 On the basis of the first embodiment, the body 1 of the spray drug delivery device of the present invention has a spray tube 8 at the front end, and the rear end of the spray tube 8 is connected to the medicine outlet 2 at the front end of the mixing chamber 3.

[0027] The spray drug delivery device of the present invention extends the spray drug delivery distance by adding a spray tube 8 at the front end of the mixing chamber 3, and realizes multiple and long-distance drug delivery. Moreover, the spray tube 8 is replaceable, and spray tubes of different lengths and outer diameters can be replaced according to different distances and outer diameters.

Embodiment 3

[0028] Example three, please refer to figure 1 with figure 2 On the basis of the first embodiment, the spray drug delivery device of the present invention is provided with an air supply control device 7, which is connected to the nozzle 4.

[0029] Specifically, the air supply control device is provided with an air inlet 13, an on-off control valve 11, and an air outlet 10. The air inlet 13 is connected to a compressed gas cylinder or an external air source, and the air outlet 10 is connected to the nozzle 4.

[0030] The gas supply control device 7 of the spray drug delivery device of the present invention, when the gas source is connected, the switch control valve 11 is pressed, and the carrier gas enters the mixing chamber 3 through the gas supply control device 7 to generate negative pressure to suck out the medicine container 6 The medicine is mixed with Chinese medicine and gas in the mixing chamber 6, and the mixture of medicine and carrier gas reaches the wound through the...

Embodiment 4

[0033] Example four, please refer to figure 1 On the basis of the first embodiment, the medicine container 6 of the medicine storage device has a channel 9 directly connected with the external atmosphere or gas pressure source.

[0034] The spray drug delivery device of the present invention adds a channel 9 to the drug container 6. When the drug is sucked out of the drug container 6 and enters the mixing chamber 3 through the drug suction tube 5, the outside air enters the drug container 6 through the side channel 9 to make The pressure in the medicine container 6 is always kept stable, so that the medicine can be continuously attracted and sprayed, and continuous and stable administration is realized, and the output air pressure is continuously stable.

[0035] Of course, the medicine container 6 of the medicine storage device can also be provided with a channel 9 on the basis of the second embodiment or the third embodiment, and the combination of the second and third embodiments...

Abstract

The invention provides a spray drug delivery device, which includes a body with a hollow inner cavity, the inner cavity of the body is provided with a mixing chamber, a drug storage device, and a nozzle, the front end of the mixing chamber has a drug outlet, and the rear end of the mixing chamber is connected to the nozzle A drug storage device is communicated with the side wall of the mixing chamber; the drug storage device includes a drug suction tube and a drug container, one end of the drug suction tube communicates with the mixing chamber, and the other end extends into the drug container through the mouth of the drug container. A spray drug delivery device of the present invention utilizes the principle of a jet pump, uses medium and low-pressure gas as a carrier, sucks the drug into the mixing chamber and mixes the two fully, then carries it again and sprays it to the wound surface to achieve stable and uniform drug delivery. , dispersed; and can replace or add any form of medicine as needed, which is convenient for the operator and improves the effect of surgical hemostasis.

Description

Technical field [0001] The invention belongs to a drug delivery device in the field of medical equipment, and particularly relates to a spray drug delivery device. Background technique [0002] Endoscopy has been born for more than 50 years, and has gone through the stage from disease diagnosis to disease treatment. The treatment of some diseases has been very effective and reliable and has even become the first choice for the treatment of some diseases, such as polyps in the digestive tract, early cancer, varicose veins, and mucous membranes. Widely used in the treatment of lower tumors. The existing endoscopic surgical treatment to hemostasis is mainly carried out by clamping the wound with hemostatic clips or electrocoagulation, but it is still insufficient in terms of diffuse venous bleeding and prevention of infection. If hemostatic and anti-infection drugs can be sprayed directly on the bleeding site, It will help the wound heal and prevent infection. At present, there ar...
