Problems solved by technology

[0004] Based on the above prior art, the inventors found that there are at least the following technical problems in the prior art: First, due to the limited interlayer space of the balloon, and the inflation of the balloon will cause the interlayer space to be further compressed, a large amount of drugs remain in the interlayer, causing drug Waste, low drug utilization, and poor operability; further led to prolonged operation time and increased unnecessary pain for patients
Secondly, the double-layer structure of the balloon also leads to a larger overall outer diameter of the drug delivery device, especially the balloon part, which is difficult to insert into the target cavity and may cause damage to the target cavity
In addition, i

preparation example Construction

[0126] Please refer to Figure 6a-Figure 6b , which is a schematic diagram of a method for preparing a drug delivery device 100 according to an embodiment of the present invention, including the following steps:

[0127] Step 1, preparing an outer catheter 102a and an inner catheter 102b;

[0128] Step 2, connecting the outer catheter 102a with a balloon 103, the balloon 103 is located at the distal end of the outer catheter 102a, and the distal end of the outer catheter 102a is reserved for an excess section 102c beyond the balloon 103;

[0129] Step 3: Insert the inner catheter 102b into the outer catheter 102a, and fuse the distal end of the inner catheter 102b and at least part of the section beyond the section 102c by heating and melting to form a bonding section.

[0130] It can be seen that after the fabrication is completed, the outer catheter 102a and the inner catheter 102b will constitute the catheter body 102, the gap between the outer catheter 102a and the inner ...

Abstract

The invention provides a drug delivery device, a preparation method thereof and a drug delivery system. The device comprises a catheter body, a balloon arranged at the far end of the catheter body anda pressure monitoring and adjusting device connected with a filling cavity and an administration cavity of the catheter body. The shape of the inflated balloon is attached to the inner wall of the target cavity; the far end of the administration cavity is provided with at least one administration port; a medicine is directly conveyed to the outer surface of the balloon through the administrationport. The outer surface of the balloon which is attached in compliance directly acts on the inner wall of the target cavity. The administration efficiency and the medicine utilization rate are high; the hole diameter and the number of the administration ports are matched with the viscosity of the medicine; the device is configured to enable the medicine to be conveyed at a certain volume flow rateunder a certain pressure for injecting the medicine, so that the medicine can be conveyed through rated pressure and flow rate under the monitoring and/or adjusting of the pressure monitoring and adjusting device, and the device is suitable for different medicine feeding requirements of different natural cavities and is beneficial to uniform medicine feeding.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a drug delivery device, a preparation method thereof, and a drug delivery system. Background technique [0002] In clinical treatment, drugs can be delivered to multiple natural orifices of the animal body, especially the human body, such as reproductive natural orifices, respiratory tracts (nasal tubes, pharyngeal tubes, trachea and bronchi), digestive tracts (esophagus and rectum) or other natural orifice. In these treatments, the drug needs to be delivered to the inner wall of the target cavity uniformly and quickly, and in most cases, the drug is also required to be effectively used to minimize waste. The drug delivery carriers currently on the market have various defects, such as low drug delivery efficiency and drug utilization, inability to uniform drug delivery, and drug delivery carriers are likely to cause secondary damage to the target cavity, which cannot meet the need...
