Specific embodiment

This utility model is further elaborated with reference to embodiment of the present utility model.

Embodiment：

A kind of ultra-smooth urinary catheter as shown in Fig. 1~5, it includes with drainage lumens 7 and rinses the conduit in chamber 8, before conduit Air bag 1 is provided with the outside of end, the drainage lumens are rinsing intracavity, and side is provided with the note connected with air bag in the cavity wall of the flushing chamber Trachea 3, the air injection pipe mouth of pipe is provided with the gas-shaft hood 4 with push rod；Flushing chamber cavity wall inner side is additionally provided with end spirally Mode be provided with aperture with the medicine-pouring pipe 2 that is bonded together of chamber cavity wall, the injection pipe end is rinsed；One section of the medicine-pouring pipe breaks Open, gap is provided with medicine-pouring pipe linker 6, the medicine-pouring pipe linker is connected through air injection pipe 3 with flushing chamber 8, and medicine-pouring pipe Device is arranged on push rod lower section, and the medicine-pouring pipe linker is provided with and through hole；When medicine-pouring pipe linker is in relaxation state, note Pencil is not connected；When push rod is promoted toward in air injection pipe pipe, medicine-pouring pipe linker is driven to chamber movement is rinsed, until medicine-pouring pipe connects The through hole of logical device moves to the gap of medicine-pouring pipe, connects medicine-pouring pipe.It is communicated between drainage lumens cavity wall and flushing chamber cavity wall Pipe, the communicating pipe connection rinses the mouth of pipe of chamber cavity wall in air bag front end；Flushing chamber cavity wall is provided with flushing hole, the punching Hole flushing is arranged on air bag and communicating pipe connection is rinsed between the mouth of pipe of chamber cavity wall.It is additionally provided with the gas-shaft hood with push rod unidirectional Valve.The effect of the communicating pipe be in order to ensure that drainage lumens are in communication with the outside, and drainage lumens and rinse chamber between do not connect.It is logical Crossing the pipeline opening of communicating pipe can be such that the liquid such as urine in urinary catheter are discharged by drain by drainage lumens.

Another embodiment of the present utility model, the push rod is followed successively by from top to bottom push handle, handle ring and push rod main body, The diameter of the push handle inserts the hole fitted seal of push rod less than the diameter of handle ring on the handle ring and gas-shaft hood.

Another embodiment of the present utility model, the catheter outer surface is coated with successively antibiotic layer and superslide layer.Institute Superslide layer is stated for hydrophilic high polymers coating or the mixture of shitosan, calcium alginate and fibroin.

Another embodiment of the present utility model, the gas injection tube wall inner side is provided with the scale of measuring length.

When using the catheter, after first catheter is inserted in urethra, first at the check valve of gas-shaft hood, enter Row inflation, the handle ring of push rod is sealed on gas-shaft hood, waits catheter successfully to derive urine, and has been rinsed after urethra, to injection Anaesthetic or other medicinal liquids needed for addition in pipe.Now, due to the state that medicine-pouring pipe is disconnection, medicinal liquid can only be in medicine-pouring pipe linker Upper part, it is impossible to flow out catheter.When needing to extract catheter, air bag deflation is tackled first, then just can extract.Put During the process of gas is as shown in Figure 6, need to be by promoting push rod, the handle ring for making push rod pushes away gas-shaft hood, and gas-shaft hood occurs deflatable Gap；Due to the effect of push rod, medicine-pouring pipe linker starts to cavity direction movement is rinsed, when push rod is by medicine-pouring pipe linker By connecting during medicine-pouring pipe, the medicinal liquid in medicine-pouring pipe will flow downward, and as the aperture of injection pipe end is discharged into urethra In, realize being automatically releasable the effect of anaesthetic during tube drawing.

Although reference be made herein to explanatory embodiment of the present utility model is described to this utility model, above-described embodiment Only this utility model preferably embodiment, embodiment of the present utility model is simultaneously not restricted to the described embodiments, it should Understand, those skilled in the art can be designed that a lot of other modification and embodiment, these modifications and embodiment will fall Within spirit disclosed in the present application and spirit.
