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 a negative pressure anal drainage drug injector and a manufacturing method thereof. The drug injector comprises at least one pipeline product for dredging liquid circulation, wherein a small-diameter fluid drainage opening is formed in the pipeline product; a plurality of seal caps are sequentially arranged on the pipeline product along the centerline of the pipeline; thin layers which are convenient for branched drainage pipelines to be inserted are arranged below the seal caps; an inclined puncture tip is arranged on the port of the pipeline product; a multi-way valve is arranged at one end of the pipeline product; and a drug injector and a negative pressure bottle are additionally arranged on the multi-way valve; and the invention also provides a manufacturing method, wherein the manufacturing method comprises steps of mixing, reacting, extrusion-molding, injection-molding, disinfecting, thinning, covering and the like. The drug injector disclosed by the invention is conducive to succession of the branch drainage pipelines as well as access of the drug injector in a drainage process, and is convenient to fix the branch drainage pipelines; and the drug injector is smooth and soft in pipeline, low in irritation to wounds, low in cost and good in 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...
