DETAILED DESCRIPTION

[0030] The embodiment of the present invention provides a urinary catheter package with a hydrophilic coating that prevents liquid from being carried out and can be squeezed and infiltrated, such as Figure 1-8 As shown, the hydrophilic coating urinary catheter package is used to load the urinary catheter 3 and includes a tube body 1 , a connector 2 , and two picks 7 .

[0031] like Figure 2 and Figure 4 As shown, the upper part of the tube body 1 is bulged and the lower part is straight. The tube body 1 is formed by buckling two identical front and rear parts. The center of the tube body 1 is a cavity for accommodating the urinary catheter 3. The bulged tube body 1 is provided with water storage tanks 4 on both sides of the cavity. The water storage tanks 4 are used to store solution 14. The side of the water storage tank 4 adjacent to the cavity is a tank wall film 41.

[0032] like Figure 2 and Figure 5As shown, a structure for fixing the paddle 7 is provided at the top of the water storage tank 4. Specifically, a straight-line limiting groove 8 is provided at the top of the water storage tank 4, and a straight-line limiting block 9 that can be inserted into the limiting groove 8 is provided at the top of the paddle 7. A structure that can pierce the groove wall film 41 is provided at the bottom of the paddle 7. Specifically, a straight-line locking tooth 11 is provided at the bottom of the paddle 7. The end of the locking tooth 11 corresponding to the groove wall film 41 is in the shape of a spike. A positioning groove 10 is provided at the bottom of the water storage tank 4. The oblique teeth at the bottom of the locking tooth 11 are engaged with the oblique teeth of the positioning groove 10. The inclined surface of the teeth is inclined toward the direction of the catheter 3, and the bottom tip of the teeth is facing the side away from the catheter 3, so that the locking tooth 11 can only move toward the groove wall film 41 in one direction and realize the reverse limit. When the latch 11 is pushed toward the slot wall film 41 , the latch 11 will disengage from the slot 10 and slide upward. When the latch 11 loses the thrust, it will get stuck on the corresponding slot 10 , so that the latch 11 maintains the current state and prevents the latch 11 from resetting backward.

[0033] Soft rubber shells 6 corresponding to the paddles 7 are arranged on both sides of the outside of the tube body 1. The middle section of the paddle 7 is in an arc shape, and the middle and lower sections of the arc correspond to the soft rubber shells 6. The soft rubber shells 6 are combined with the notch of the tube body 1 by secondary injection molding. The middle of the soft rubber shells 6 is convex.

[0034] The upper and lower surfaces of the water storage tank 4 are covered with a sealing film 12. The sealing film 12 is used to seal the edge gap of the water storage tank 4.

[0035] The water storage tank wall near the urinary catheter 3, that is, the tank wall film 41, has been thinned to facilitate being pierced by the plectrum 7.

[0036] like Figure 2 and 3 As shown, the joint 2 includes a joint pipe opening 23, a joint body 21, and an extended pipe section 22 arranged in sequence from top to bottom. The joint body 21 is used to be fixed on the pipe body 1, and can be combined with the pipe body 1 by secondary injection molding.

[0037] The return groove 5 is formed between the extended pipe section 22 and the groove wall film 41. The extended pipe section 22 is lengthened, and the two ends of the outer side tube body 1 are concave inward to form an umbrella-shaped cap 28. The umbrella-shaped cap 28 is high in the middle and low on both sides, which can greatly increase the internal area of ​​the return groove 5.

[0038] The joint pipe opening 23 is used to cover the cover 26 .

[0039] The extension tube section 22 is provided with a partition film 13 in close contact with the urinary catheter 3. The partition film 13 is made of soft material and has a cross opening in the middle, through which the urinary catheter 3 can be inserted, while preventing the solution 14 from flowing out of the package along the connector 2.

[0040] A circle of wavy corrugated card slot 1 24 is arranged on the outer circle of the joint pipe mouth 23, and a circle of corrugated card slot 2 27 matching with the corrugated card slot 1 24 is arranged at the bottom of the cover 26. The cover 26 and the joint pipe mouth 23 are matched by hard clamping, so that the sealing is good and the cover 26 is not easy to fall out. Considering that there will be a certain resistance when opening, the outer periphery of the cover adopts a "sin" skirt design with a large bottom and a small top and a circle of vertical anti-slip design. When opening, the cover 26 can be rotated, and the wavy path of the corrugated card slot 1 24 and the card slot 2 27 reduces the difficulty of opening without affecting the use effect.

[0041] The outer ring of the cover 26 is provided with anti-skid corrugations 29 above the corrugated card slot 27. There is a certain distance between the anti-skid corrugations 29 and the corrugated card slot 27 to accommodate fingers. The anti-skid corrugations 29 serve as a fulcrum for the cover 26 to rotate and assist in unscrewing the cover 26.

[0042] Working principle: Figure 6 As shown, when using the catheter 3, the operator can press the soft rubber button 6 with two fingers, and the middle and lower part of the paddle 7 will be subjected to an extrusion force. Since the upper part of the paddle 7 is fixed and the lower part is deformed inward, the bottom of the paddle 7 will press against the groove wall film 41 and break the groove wall film 41. When the groove wall film 41 deforms outward until it touches the extension pipe section 22 of the connector 2, it will no longer change outward. The latch teeth 11 at the bottom of the paddle 7 will be stuck and cannot be retracted because they cooperate with the saw-shaped positioning slots 10 at the bottom of the water storage tank 4, and the groove wall film 41 will always be in the "open" state under the support of the paddle 7. The solution 14 flows down along the tube wall and infiltrates the catheter 3.

[0043] When the prescribed soaking time is reached, one hand holds the tube body 1, and the other hand holds the vertical line to turn the cover 26. Due to the wave-shaped step design at the cover 26 and the joint pipe mouth 23, the cover 26 can be easily pushed upward, and after the cover 26 is opened, the catheter 3 can be pulled out. Due to the partition membrane 13, the excess solution 14 on the catheter 3 will be drained into the tube.

[0044] Due to different operators, when taking out the catheter 3 or after taking out the catheter 3, the orientation of the catheter body 1 is not fixed, and it may be vertical or horizontal, and even the cover 26 may be facing downward. Figure 7 As shown in FIG. 1 , when the package is completely inverted, most of the solution 14 at the bottom will enter the return groove 5, and a part of it will enter the water storage tank 4 from the opening of the groove wall film 41. Then the liquid level of the solution 14 will be much lower than the outlet of the extension tube section 22. Even if it is shaken, it is not easy to flow out. Another method is to place the urinary catheter 3 sideways or take it sideways, such as Figure 8As shown, due to the "open" design of the groove wall film 41, the solution 14 will also flow into the water storage tank 4 along the opening, and a part of it will also flow into the return tank 5. The "dry and wet separation" of the urinary catheter 3 is truly realized.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
