Adopt this neotype urine bag of antiseep connect the surface of connecting body 1 is provided with annular flange 3, and will annular flange 3 with the tip that connects body 1 diameter to the utmost separates the certain distance setting, when catheter 2 and articulate, exists the step in the cladding section of catheter more easily, has reduced annular flange 3 sets up on the region joint body 1 and catheter 2 between the complex clearance of joint, also make this neotype urine bag connect even if do not insert completely in the drainage chamber of catheter 2, also can form inseparable reliable connection cooperation rather than, reduced between the two because of dragging and lead to connecting the risk that the pine takes off, improved this neotype security in clinical use.

Specifically, the inventor considers in this embodiment, the great urine bag of specification may be used clinically, be used for patient once only to store more urine, nevertheless can appear like this, because 2 internal diameters of catheter are on the small side and the external diameter of urine bag cone coupling bottom is on the large side, the cone coupling is difficult to the condition of inserting 2 drainage chambeies of catheter completely for be difficult to form effectual joint between catheter 2 and the urine bag cone coupling, if the patient has actions such as standing up in the drainage process, the connection between the two is dragged and is very easily caused catheter 2 and drops, the risk that the urine leaks appears. Based on this, in this embodiment, the inventor sets up the annular flange 3 on the outer surface of the connector body 1, and will the annular flange 3 with the tip that the diameter of the connector body 1 is the biggest is separated by a certain distance and is set up, has reduced on the annular flange 3 region of setting up the clearance of joint cooperation between the connector body 1 and the catheter 2, makes the urine bag joint of this novel need not insert in the drainage chamber of catheter 2 completely, also can form inseparable connection cooperation with it, has avoided the connection pine between the two, has improved the novel security in clinical use.

In this embodiment, the nature of providing the annular flange 3 on the connector body 1 is to change the original linear diameter change of the taper connector, and advance the area of the connector body 1 with the largest diameter, so as to reduce the overall length of the connector body 1, so that the resistance of the connector body 1 during the insertion of the catheter 2 is reduced, and the connector body 1 can form a tight connection without being inserted into the catheter 2.

As a preferred embodiment, in addition to the above manner, the annular flanges 3 are further provided in a plurality of ways along the longitudinal direction of the joint body 1. Adopt this kind of structure setting, make this novel catheter 2 that can cooperate different specifications use.

In the present embodiment, the inventor considers that, because the installation position of the annular flange 3 on the connector body 1 is fixed, when the annular flange 3 is applied to the urinary catheter 2 with a smaller diameter, the annular flange 3 still cannot be inserted into the urinary catheter 2, and therefore, in the present embodiment, the inventor arranges the annular flange 3 into a plurality of channels along the length direction of the connector body 1. Make the diameter of annular flange 3 forms the change from small to big to avoid the appearance of above-mentioned condition, improved this novel practicality in clinical use. Meanwhile, the annular flanges 3 are arranged in multiple ways, on one hand, when the diameter of the catheter 2 is large, the annular flanges 3 can be coated in multiple ways, the connection reliability is further improved, on the other hand, when the diameter of the catheter 2 is small, the annular flanges 3 with small diameters can be coated in the annular flanges 3, the reliable connection is formed, and therefore the application range is further expanded.

Can further reduce joint complex clearance between joint body 1 and the catheter 2 has further avoided the connection pine between the two to take off, has improved this novel security in clinical use.

In a preferred embodiment, in addition to the above-described mode, the arrangement pitch between the plurality of annular flanges 3 is gradually decreased in a direction in which the liquid flows into the joint body 1.

In the embodiment, the inventor considers that a plurality of annular flanges 3 are arranged in the scheme, so that the novel catheter can be matched with catheters 2 with more specifications for use, and the practicability of the novel catheter in clinical use is improved; simultaneously, the multichannel of setting cyclic annular flange 3 can further reduce joint body 1 and catheter 2 between the complex clearance of joint, further avoided the connection pine between the two to take off, improved this novel security in clinical use. However, the defects still exist, the arrangement of the plurality of annular flanges 3 also changes the overall size of the joint body 1 to a certain extent, so that the overall diameter size of the joint body 1 is increased, and in the process of inserting the joint body 1 into the urinary catheter 2, the annular flanges 3 inserted into the urinary catheter 2 all generate resistance to block the non-inserted part of the joint body 1. In this respect, in the present embodiment, the arrangement pitch between the plurality of annular flanges 3 is gradually decreased in the direction in which the liquid flows into the joint body 1. So, make on the joint body 1, the whole length of cyclic annular flange 3 reduces, thereby has reduced the resistance when connecting body 1 and inserting has further improved the practicality in clinical use of this novel.

In a preferred embodiment, in addition to the above aspect, the annular flange 3 has a triangular cross-sectional shape, the side wall of the annular flange 3 extends in a direction in which the pipe diameter of the joint body 1 is reduced, and an angle formed between a cross-sectional edge of the side wall of the annular flange 3 and a cross-sectional edge of the side wall of the joint body 1 is an acute angle smaller than 15 °. Adopt this kind of structure setting, on the one hand, guaranteed cyclic annular flange 3's structural strength has avoided connect body 1 at male in-process, cyclic annular flange 3 warp and damages, leads to the seepage of drainage in-process urine, has improved the novel security in clinical use, on the other hand, this kind of structure setting cyclic annular flange 3 has further reduced resistance when connecting body 1 and inserting has improved the utility model discloses practicality in clinical use.

In a preferred embodiment, in addition to the above-mentioned manner, a cross-sectional edge line of the top wall of the annular flange 3 is perpendicular to the central axis of the joint body 1. Adopt this kind of structure setting, when guaranteeing to connect between body 1 and the catheter 2 stability of being connected, made things convenient for after the drainage between the two to be connected and throw off, further improved this novel practicality in clinical use.

In particular, the inventors consider that, when the connector body 1 is inserted into a catheter, the annular flange 3 will lift the side wall of the catheter 2, and the annular flange 3 will also be "embedded" in the side wall thereof. When the connection between the connector body 1 and the catheter 2 is pulled, the top wall of the annular flange 3 pushes the side wall of the catheter 2 to form a bulge, and the connector body 1 is prevented from falling out. Thus, although the connection stability between the connector body 1 and the catheter 2 is ensured, the separation of the connector body and the catheter 2 after drainage is also hindered to a certain extent; if the top wall of the annular flange 3 is inclined in the direction in which the diameter of the adapter body 1 increases, the above problem can be effectively solved, but the connection between the adapter body 1 and the catheter 2 is easily released by pulling. To solve the above problem, in the present embodiment, the inventor sets the cross-sectional edge line of the top wall of the annular flange 3 to be perpendicular to the central axis of the joint body 1. So, make when connecting between body 1 and the catheter 2 and receiving the drag, the size that the roof of cyclic annular flange 3 promoted the uplift of 2 lateral walls of catheter formation is in relative "moderate" state, thereby both guaranteed connect between body 1 and the catheter 2 when stable, still made things convenient for after the drainage to connect between the two and throw off, further improved the utility model discloses practicality in clinical use.

Example 2

As shown in fig. 1 to fig. 3, the urine bag joint of the present invention against leakage, further, a plurality of saw teeth 4 are disposed on the side wall of the annular flange 3, and the saw teeth 4 are used for increasing the friction force between the joint body 1 and the catheter 2. By adopting the structure, the connection stability between the two is further ensured, and the safety of the novel device in clinical use is improved.

As a preferred embodiment, in addition to the above manner, further, adjacent saw teeth 4 are disposed at a certain distance.

In the above scheme, still set up a plurality of sawtooth 4 on the lateral wall of cyclic annular flange 3, increased the frictional force between joint body 1 and the catheter 2 has further guaranteed the connection stability between the two, has improved this novel security in clinical use. However, there is still a disadvantage that the contact area between the teeth of the saw teeth 4 and the side wall of the catheter 2 is too small to form an effective barrier to urine, so that there is a risk of urine leakage. Therefore, in the present embodiment, the inventors set the adjacent saw teeth 4 at a certain distance. Utilize the elastic contraction power of catheter 2 self, fill because sawtooth 4 sets up the back, cause the area of contact undersize's that forms between its and the lateral wall of catheter 2 problem to avoid the emergence of urine seepage, improved the novel security in clinical practice.

As a preferred embodiment, on the basis of the above manner, further, a plurality of saw teeth 4 are arranged on the side wall of the annular flange 3 near the top wall side.

In the present embodiment, the inventor considers that, since the cross-sectional shape of the annular flange 3 is triangular, and an angle formed between a cross-sectional edge line of the side wall of the annular flange 3 and a cross-sectional edge line of the side wall of the joint body 1 is an acute angle smaller than 15 °. So that the lower half of the annular flange 3 is formed with a small projection, and at this portion, the gain in friction provided by the provision of the serrations 4 is small. Based on this, in this embodiment, the inventor sets the saw teeth 4 on the side wall of the annular flange 3 near the top wall, so as to reduce the production and manufacturing costs of the present invention to some extent, and is more beneficial to the popularization of the present invention in clinical application.

In a preferred embodiment, in addition to the above, the tips of the saw teeth 4 are disposed toward the top wall of the annular flange 3. By adopting the structure, the capability of the sawteeth 4 to interlock the side wall of the catheter 2 is further improved, so that the catheter 2 is less prone to sliding at the contact part of the side wall of the annular flange 3, the connection loosening between the two is further avoided, and the safety of the novel catheter in clinical use is improved.
