DETAILED DESCRIPTION

[0030] The embodiment of the present application provides a hydrophilic coating catheter package which prevents liquid from being taken out and extrusion infiltration, as shown in the figure. Figures 1-8 The hydrophilic coating catheter package is used for loading a catheter 3 and comprises a tube body 1, a joint 2 and two tabs 7.

[0031] As shown in the figures, Figure 2 and Figure 4 The upper part of the tube body 1 is in a bulging shape and the lower part is in a straight tube shape. The tube body 1 is buckled by two same front and rear parts. The center of the tube body 1 is a cavity for accommodating the catheter 3. The two sides of the bulging tube body 1 are provided with water storage tanks 4. The water storage tanks 4 are used for storing a solution 14. One side of the water storage tank 4 adjacent to the cavity is a slot wall film 41.

[0032] As shown in the figures, Figure 2 and Figure 5As shown, the top of the water tank 4 is provided with a structure for fixing the lever 7. Specifically, the top of the water tank 4 is provided with a straight-line limiting groove 8, and the top of the lever 7 is provided with a straight-line limiting block 9 that can be inserted into the limiting groove 8. The bottom of the lever 7 is provided with a structure that can pierce the tank wall membrane 41. Specifically, the bottom of the lever 7 is provided with a straight-line locking tooth 11. The end of the locking tooth 11 corresponding to the tank wall membrane 41 is spike-shaped. The bottom of the water tank 4 is provided with a positioning groove 10. The oblique teeth at the bottom of the locking tooth 11 and the oblique teeth of the positioning groove 10 interlock with each other. The oblique surface of the teeth is inclined towards the catheter 3, and the bottom tip of the teeth faces away from the catheter 3, so that the locking tooth 11 can only move in one direction towards the tank wall membrane 41 and achieves reverse limiting. When the locking tooth 11 is pushed toward the diaphragm 41 of the groove wall, the locking tooth 11 will slide upward away from the locking groove 10. When the locking tooth 11 loses its thrust, it will be locked in the corresponding locking groove 10, so that the locking tooth 11 maintains its current state and prevents the locking tooth 11 from resetting backward.

[0033] The tube body 1 has soft rubber covers 6 on both sides corresponding to the paddle 7. The middle section of the paddle 7 is arc-shaped, and the lower middle section of the arc corresponds to the soft rubber cover 6. The soft rubber cover 6 is integrally formed with the notch of the tube body 1 by a two-stage injection molding process. The middle of the soft rubber cover 6 protrudes.

[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 gaps of the water storage tank 4.

[0035] The water reservoir wall near the catheter 3, i.e., the membrane 41 of the reservoir wall, has been thinned to make it easier for the pick 7 to puncture.

[0036] like Figure 2 and 3 As shown, the connector 2 includes a connector port 23, a connector body 21, and an extension pipe section 22 arranged sequentially from top to bottom. The connector body 21 is used to fix it to the pipe body 1 and can be integrated with the pipe body 1 by secondary injection molding.

[0037] A return trough 5 is formed between the extension pipe section 22 and the membrane 41 of the trough wall. The extension pipe section 22 has been lengthened, and both ends of the outer side of the pipe body 1 are concave inward to form an umbrella-shaped cap 28. The umbrella-shaped cap 28 has a shape that is high in the middle and low on both sides. This can greatly increase the internal area of ​​the return trough 5.

[0038] The connector port 23 is used to cover the cap 26.

[0039] The extension tube 22 is equipped with a septum membrane 13 that is in close contact with the catheter 3. The septum membrane 13 is made of soft material and has a cross-shaped opening in the middle, through which the catheter 3 can be inserted, while preventing the solution 14 from flowing out of the packaging along the connector 2.

[0040] The outer ring of the joint pipe 23 is provided with a ring of wavy corrugated slot 24, and the bottom of the cover 26 is provided with a ring of corrugated slot 27 matched with the corrugated slot 24. The cover 26 and the joint pipe 23 are hard to fall out by hard card cooperation, and the cover 26 is not easy to fall out. Considering that there is a certain resistance when opening, the "sin" skirt design with large bottom and small top is adopted on the periphery of the cover, and a ring of vertical anti-skid design is added. When opening, the cover 26 can be rotated, and the wavy path of the corrugated slot 24 and the slot 27 can reduce the difficulty of opening and not affect the use effect.

[0041] The outer ring of the cover 26 is further provided with an anti-skid corrugation 29 above the corrugated slot 27, and the anti-skid corrugation 29 has a certain spacing with the corrugated slot 27 for accommodating fingers. The anti-skid corrugation 29 serves as the fulcrum for rotating the cover 26, and is used to assist in unscrewing the cover 26.

[0042] Working principle: as Figure 6 shown, when the catheter 3 is used, the operator can press the soft rubber shell 6 with two fingers, and the lower part of the paddle 7 will be subjected to a squeezing force. Since the upper part of the paddle 7 is fixed, the lower part will deform inward, and the bottom of the paddle 7 will abut against the groove wall membrane 41 and break the groove wall membrane 41. When the groove wall membrane 41 deforms outward until it touches the extension pipe section 22 of the joint 2, it will no longer change outward. The pawl 11 at the bottom of the paddle 7 is clamped by the sawtooth-shaped positioning slot 10 at the bottom of the water storage tank 4, so that it is clamped and cannot be returned, and the groove wall membrane 41 will also be in an "open" state under the support of the paddle 7. The solution 14 flows down along the pipe wall to soak the catheter 3.

[0043] When the specified soaking time arrives, one hand holds the pipe body 1, and the other hand holds the vertical anti-skid cover 26. Since the cover 26 and the joint pipe 23 have a wavy step design, the cover 26 can be easily pushed up. After the cover 26 is opened, the catheter 3 can be taken out. Since there is a partition membrane 13, the excess solution 14 adhered to the catheter 3 will be drained into the pipe.

[0044] Due to different operators, the orientation of the pipe body 1 is not fixed when taking out the catheter 3 or after taking out the catheter 3, which can be vertical or horizontal, or even with the cover 26 downward. As Figure 7 shown, when the package is completely inverted, the lower solution 14 will mostly enter the back tank 5, and a part of it will enter the water storage tank 4 from the opening of the groove wall membrane 41. Then the liquid level of the solution 14 will be much lower than the outlet of the extension pipe section 22. Even if it is shaken, it is not easy to flow out. Another is to place or take out the catheter 3 horizontally, as Figure 8As shown, due to the "open" design of the groove wall film 41, the solution 14 will also enter the water storage groove 4 along the opening, and part of it will also enter the back-cleaning groove 5. The "dry and wet separation" of the catheter 3 is truly realized.

[0045] While the embodiments of the application have been illustrated and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the spirit and scope of the application, which is defined by the appended claims and their equivalents.
