Self-coated non- vascular orifice insertion tube

Abstract

The invention discloses a self-coated non-vascular orifice insertion tube, and belongs to the technical field of medical instruments. The self-coated non-vascular orifice insertion tube comprises a non-vascular orifice insertion tube, and is characterized in that the right end of an outer cylinder body sleeves the outer wall of the left end of an inner cylinder body, an annular piston is arrangedin an annular cavity of the inner cylinder body, the annular piston is connected with the right end of a sleeve, and the left end of the sleeve is connected with an annular top plate; a first compression spring is arranged between the annular piston and the left end wall of the inner cylinder body, the inner wall of the sleeve is provided with a plurality of fixing grooves, grooves corresponding to the fixing grooves are formed in the lower end wall of the annular cavity of the inner cylinder body, a ratchet bar is fixedly arranged in each fixing groove, the outer wall of a positioning wheel is provided with a plurality of arch-shaped protrusions arranged uniformly in a circumference, an arc-shaped groove is formed between every two arc-shaped projections, and the inner side end of a guiding ball abuts in an arc-shaped groove of the positioning wheel. Compared with the prior art, the self-coated non-vascular orifice insertion tube has the advantages of simple structure and reasonable design.

Description

technical field [0001] The invention relates to a medical device, in particular to a device capable of performing rapid secondary coating on a non-vascular lumen insertion tube. Background technique [0002] Non-vascular insertion tubes refer to tubes that are inserted into the human or animal body through the surface cavity and stay for a period of time, such as gastric tubes, urinary catheters, tracheal tubes, drainage tubes, etc. There are many types of cavity insertion tubes at present. Except for the direct incision or wound insertion of the drainage tube, other insertion tubes are inserted from the surface exposed cavity, such as gastric tube and endotracheal tube are inserted from the nasal cavity. [0003] During the insertion process, different insertion tubes have different configuration requirements. For example, nasogastric feeding tubes and urinary catheters only need basic lubrication, but if they need to be indwelled for a long time, in order to avoid local ir...

AI Technical Summary

Problems solved by technology

Because the lubricating oil required for the insertion of indwelling gastric tube or indwelling urinary catheter has fat-dissolving effect, the following defects are caused: ①The pre-lubricated cavity insertion tube widely used in existing hospitals, and the drug-coated insertion tube cannot be pre-lubricated operation, otherwise the activity is easily dissolved in lubricating oil, which is not conducive to local slow release; If it is long, it may cause the loss of the above medicinal properties

The use of this anesthetic drug also requires secondary treatment of the catheter during the operation, and during the treatment process, manual smearing, uneven thickness, and easy control of the drug dose
