Description

Medicine propelling device and medicine propelling tube for treating wound in inner chamber

The present invention relates to a medicament propelling device and its medicament propelling tube for treating wounds in an inner chamber, in particular, it can eliminate the static electricity of the medicament propelling tube, and avoid the medicament being blocked in the medicament propelling tube by electrostatic adsorption when using powdered medicament 's invention.

Endoscopy is a powerful tool used to examine diseases in the inner chambers of the human body such as the stomach and bladder.

The traditional endoscope only has the function of observation and inspection. When diseases in the inner chamber are found, the doctor needs to evaluate the follow-up treatment after removing the endoscope. Since endoscopy is an invasive examination, and invasive treatment is usually required for diseases in the inner chamber, multiple invasive examinations and treatments not only cause discomfort to the patient, but also increase the risk of infection.

Therefore, the current endoscope is usually attached with a knife that can shave polyps, or a treatment device such as a drug delivery catheter that can administer drugs to wounds such as ulcers. Uncomfortable and also reduces the risk of infection.

As for the device for endoscopic drug delivery, the inventor found that the drug delivery catheter used for drug delivery is generally made of Teflon plastic. This plastic catheter will have extremely high static electricity on the surface of the catheter. The part that protrudes into the endoscope will be discharged due to the metal mesh of the endoscope, but the part exposed outside the endoscope still has a certain length. When the medicine to be administered is powder, it is often caused by The phenomenon of electrostatic adsorption causes the drug to be blocked in the part of the drug delivery catheter exposed to the endoscope. The inventor's actual test found that the static electricity in the drug delivery catheter can be as high as 13000V to 23000V.

Therefore, the present invention provides a medicine propelling device for treating wounds in an inner chamber and a medicine propelling tube thereof, which are used in combination with an endoscope.

The medicine propelling tube includes an inner tube and an electrostatic discharge tube. The inner tube has a protruding section and an exposed section. The protruding section protrudes into the endoscope, and the electrostatic discharge tube is sleeved on the exposed section. At least a part of the electrostatic discharge pipe sleeved on the exposed section of the inner tube is 80% of the length of the exposed section calculated from the connection between the exposed section of the inner tube and the control valve. The medicine propelling device also includes: a control valve, which has a pipe connection end, a medicine inlet end and a positive pressure inlet end, which can selectively control the connection between the pipe connection end and the medicine inlet end, or control the pipe connection end to communicate with the medicine inlet end. The end is communicated with the positive pressure inlet end, the pipe connection end is connected to the outer exposed section of the inner tube; a medicine supply pipe is connected to the medicine inlet end; a first air supply unit is connected to the medicine supply pipe; an air inlet A pipe is connected to the positive pressure air inlet end; a second air supply unit is connected to the air intake pipe; a processor is electrically connected to the control valve, the first air supply unit and the second air supply unit. In addition, in the medicine propelling device, the medicine supply pipe and the air intake pipe can also be connected through a three-way valve, and a single air supply unit can be connected to the three-way valve, and the three-way valve can be controlled by controlling the three-way valve. The valve communicates the air supply unit and the medicine supply pipe, or communicates the air supply unit and the air intake pipe to selectively supply air.

Further, the electrostatic discharge tube is made of electrostatically conductive material.

Further, the electrostatic discharge tube has a grounding end.

Further, the pipe connection end of the control valve includes a conical sleeve, and a fixing ring is locked outside the sleeve.

Through the above technical features, the following effects can be achieved:

1. The present invention can avoid the problem of blockage caused by electrostatic adsorption of the powdered medicament during administration by covering the exposed section of the inner tube of the medicament propelling tube with an electrostatic discharge tube. From the connection between the exposed section of the inner tube and the control valve, the portion of the electrostatic discharge tube sleeved on the exposed section of the inner tube accounts for 80% of the length of the exposed section, which can effectively overcome the problem of electrostatic adsorption.

2. In the present invention, the processor selectively controls the pipe connection end of the control valve to communicate with the drug inlet end or controls the pipe connection end to communicate with the positive pressure inlet end. When the pipe connection end is communicated with the drug inlet end, the drug administration is continued; and when the drug administration is stopped, the pipe connection end is communicated with the positive pressure intake end, and gas is introduced to maintain the drug propelling tube The positive pressure of the inner tube can prevent the inner tube of the medicine propelling tube from being blocked due to the backflow of the medicine and blood in the inner chamber.
