The utility model discloses further set up to: the catheter body is a pipeline made of natural rubber, silicon rubber or polyvinyl chloride (PVC).

Through above-mentioned technical scheme, natural rubber, silicon rubber or polyvinyl chloride (PVC) are soft state, are soft material, and when using, the head can rotate around the splice bar, opens the second and washs the mouth.

The utility model discloses further set up to: the first cleaning opening is provided with a plurality of first cleaning openings along the axis direction of the joint, and the first cleaning openings form a straight line.

Through above-mentioned technical scheme, it has a plurality of to set up the washing mouth for the cleaning performance of washing mouth is better.

The utility model discloses further set up to: the connector is cylindrical, and the diameter of the end, far away from the catheter body, of the connector is smaller than the diameter of the end, close to the catheter body, of the connector.

Through above-mentioned technical scheme, the diameter that sets up the joint is close to the inside one end of urethra less for the packing force of head in the joint is bigger, makes things convenient for the rotation of head, conveniently opens the second and washs the mouth.

The utility model discloses further set up to: and a convex ring is arranged on the inner wall of the interface channel of the joint.

The utility model discloses further set up to: one or more convex rings are arranged.

Through above-mentioned technical scheme, set up the bulge loop, the bulge loop can block opening gap department, and the convenience is when the somatic part of catheter body is pulled out, and the head of catheter body rotates, has further made things convenient for opening of second washing mouth.

The utility model discloses further set up to: the catheter body is cylindrical.

To sum up, the utility model discloses following beneficial effect has:

(1) the opening gap is formed in the peripheral side of the catheter body, so that the second cleaning opening can be opened from the gap, and the purpose of conveniently guiding cleaning liquid for cleaning is achieved;

(2) the end, close to the interior of the urethra, of the joint is smaller in diameter, so that the pressing force of the head in the joint is larger, the head can rotate conveniently, and the second cleaning port can be opened conveniently;

(3) through setting up the bulge loop, the bulge loop can block opening gap department, and the convenience is when the somatic part of catheter body is pulled out, and the head of catheter body rotates, has further made things convenient for opening of second washing mouth.

Detailed Description

The present invention will be described in further detail with reference to the following examples and drawings, but the embodiments of the present invention are not limited thereto.

Example 1:

the utility model provides a novel catheter, combines fig. 1 and fig. 2, includes to connect 1 and catheter body 2, connects 1 and has interface channel 11 along its axial, and catheter body 2 has catheterization passageway 21 along its axial, and the plug of 2 detachable of catheter body is installed in interface channel 11, and the first washing mouth 12 of through connection 1 is seted up to interface channel 11's inner wall. The catheter body 2 is made of a flexible material, such as a pipeline made of natural rubber, silicon rubber or polyvinyl chloride (PVC), an opening gap 22 is formed in the periphery of one end, close to the connector 1, of the catheter body 2, the opening gap 22 divides the catheter body 2 into a head portion 3 and a body portion 4, a connecting rib 5 is formed between the head portion 3 and the body portion 4, the head portion 3 rotates around the connecting rib 5 to open a second cleaning opening 6, and the second cleaning opening 6 is communicated with the first cleaning opening 12.

Wherein, the opening length of the opening gap 22 accounts for one half to four fifths of the circumference of the catheter body 12, and the remaining length of the connecting rib 5 accounts for one fifth to one half of the circumference of the catheter body 12. The connector 1 is cylindrical, and the catheter body 2 is cylindrical.

The number of the first cleaning ports 12 is three along the axial direction of the joint 1, the three first cleaning ports 12 form a straight line, a convex ring 13 is arranged on the inner wall of the interface channel 11 of the joint 1, and one or more convex rings 13 are arranged.

When in use: because the urethra is a channel in the flesh of a human body, the urethra is tightened due to the flesh in the direction towards the inside of the urethra, and therefore, the pressure applied to the end, inserted into the urethra, of the catheter body 2 is higher, namely the pressure applied to the head 3 is higher than the pressure applied to the body 4. When rinsing urethra during operation, extract catheter body 2 to the outside of human body, because the pressure that head 3 received is bigger, make head 3 rotate along opening gap 22, opening gap 22 is opened, form second washing mouth 6, rotate catheter body 2, make first washing mouth 12 and second washing mouth 22 align, inject the washing liquid in catheter body 2's catheterization passageway, the washing liquid washs mouthful 12 and second through first washing and washs in mouthful 22 entering joint 1's the periphery side, and enter into to the urethra, wash, reach abluent purpose. Wherein, the cleaning solution is generally physiological saline.

Example 2:

a novel catheter, combine figure 3, this embodiment 2 and embodiment 1's difference lies in that connects 1 and is the round platform type, and connects 1 and keep away from the diameter of catheter body 2 one end and be less than the diameter that connects 1 and be close to catheter body 2 one end.

It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection. It should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
