Problems solved by technology

[0003] At present, colorectal surgery and anal surgery are very common operations. After the operation, it is necessary to drain the colorectum and anus to ensure a certain pressure in the anorectum and smooth discharge of intestinal fluid and secretions. The current drainage devices mostly use two-way negative The drainage tube connected to the pressure bottle may be diverted or connected to multiple injectors with different liquid medicines during the drainage process. The original three-way valve cannot meet the demand
[0004] At present, the production of small-diameter drainage tubes needs to be punched or drilled by mechanical, electrical, optical and chemical means. It is very difficult to complete some drilling steps on the product, especially to make drainage tubes that are convenient for branch tube connection.

Abstract

The invention discloses an anal negative pressure drug injector, which comprises at least one pipeline product for dredging liquid circulation, the pipeline product is provided with a small-diameter fluid drainage port, and the pipeline product is sequentially arranged along the center line of the pipeline. There are multiple covers, and a thin cortex is provided under the cover to facilitate the insertion of branch drainage pipes. The port of the pipeline product is provided with an inclined puncture tip, and one end of the pipeline product is provided with a multi-way valve. A drug injector and a negative pressure bottle are also provided, and the manufacturing method includes the steps of mixing, reacting, extruding, injecting, sterilizing, thinning, and capping. The invention is beneficial to the connection of branch drainage pipes and the connection of drug injectors in the drainage process, facilitates the fixing of branch drainage pipes, has smooth and soft pipes, less stimulation to wounds, low cost and good drainage effect.

Description

technical field [0001] The invention relates to the medical field, in particular to an anal negative pressure drainage injector and a manufacturing method thereof. Background technique [0002] Negative pressure drainage is a technique of negative pressure suction with VSD material, semi-permeable membrane, three-way valve and negative pressure suction device. With the growth of social economy, the patients with intractable diseases are gradually increasing, therefore, the patients treated by drainage are also gradually increasing. [0003] At present, colorectal surgery and anal surgery are very common operations. After the operation, it is necessary to drain the colorectum and anus to ensure a certain pressure in the anorectum and smooth discharge of intestinal fluid and secretions. The current drainage devices mostly use two-way negative The drainage tube connected to the pressure bottle may be diverted or connected to multiple injectors with different liquid medicines d...
