Abstract

The utility model relates to a catheter which comprises a catheter body, wherein the front end of the catheter pipe is provided with a urine inlet, and the rear end of the catheter pipe is communicated with a urine outlet and a cleaning injection hole. The catheter is characterized in that the outer end of the cleaning injection hole is communicated with a syringe connecting mouth which is externally provided with a protecting sleeve; the protecting sleeve is connected with the outer end surface of the cleaning injection hole in a closed way; and the inner diameter of an external port of the protecting sleeve is larger than that of the inner end of the protecting sleeve. The catheter is provided with the syringe connecting mouth and the protecting sleeve, the front end of a syringe is inserted into the part between the protecting sleeve and the syringe connecting mouth during use, and the front end of the syringe is blocked between protecting sleeve and the syringe connecting mouth since the inner diameter of the external port of the protecting sleeve is larger than that of the inner end of the protecting sleeve; and the catheter is good in connecting effect, hard to slip and convenient to use and operate.

Description

Catheter

Technical field

This utility model relates to a kind of medical apparatus and instruments, relates in particular to a kind of catheter.

Background technology

In giving the process of patient's urethral catheterization, need sometimes the washed bladder to patient, present way is directly syringe to be inserted to clean injection port, then water filling, but too sliding, not easy to operate owing to cleaning the injection port pipe end.

The utility model content

This utility model is for deficiency, and a kind of easy to operate, catheter that result of use is good is provided.

The technical scheme that this utility model solves the problems of the technologies described above is as follows:

A kind of catheter, comprise body, the body front end has urine filling mouth, the body rear end is communicated with urine outlet and cleans injection port, it is characterized in that, clean the injection port outer end and be communicated with the syringe connection, syringe connection outside is provided with sheath, sheath and cleaning injection port airtight linking to each other of outer face, the internal diameter of sheath external end mouth is greater than the internal diameter of sheath inner end.

This utility model is provided with syringe connection and sheath, front end with syringe during use inserts between sheath and the syringe connection, because the internal diameter of sheath external end mouth is greater than the internal diameter of sheath inner end, the front end of syringe can be stuck between sheath and the syringe connection, good connecting effect, be difficult for slippage, easy for operation.

Description of drawings

Fig. 1 is structural representation of the present utility model.

In the accompanying drawing:

1, body; 2, urine outlet; 3, clean injection port; 4, sheath; 5, syringe connection; 6, urine filling mouth.

The specific embodiment

Below in conjunction with accompanying drawing principle of the present utility model and feature are described, institute gives an actual example and only is used for explaining this utility model, is not be used to limiting scope of the present utility model.

A kind of catheter, as shown in Figure 1, comprise body 1, body 1 front end has urine filling mouth 6, body 1 rear end is communicated with urine outlet 2 and cleans injection port 3, cleans injection port 3 outer ends and is communicated with syringe connection 5, and syringe connection 5 outsides are provided with sheath 4, sheath 4 and cleaning injection port airtight linking to each other of 3 outer faces, the internal diameter of sheath 4 external port is greater than the internal diameter of sheath 4 inner ends.

The above only is preferred embodiment of the present utility model, and is in order to limit this utility model, not all within spirit of the present utility model and principle, any modification of doing, is equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.

Claims
