[0017] In order to make the purpose, technical scheme and advantage of the utility model more clearly, the following is in combination with the drawing and embodiment, and the utility model is further explained in detail. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

[0018] In order to explain the technical scheme described in the utility model, the following is explained through specific embodiments.

[0019] As Figures 1-3 The utility model discloses a catheter convenient for urine sample collection provided by the embodiment, including upper catheter 1 and lower catheter 2, and the upper and lower catheter are connected through three -way pipe 3, and the lateral arm branch 31 of three -way pipe 3 is connected with collection connector 5 through intermediate pipe 4, and the collection connector 5 includes casing 51 and the hole plate 52 of laterally arranged casing 51, and the bottom of casing 51 has collection hole 53, and there is a guide ring 54 between hole plate 52 and collection hole 53, and the outer periphery of guide ring 54 is a set of commutation cavity 55, and the lateral wall of guide ring 54 is also opened a set of commutation hole 56, and the central position of hole plate 52 is provided with guide rod 57, and the tail end of guide rod 57 has lower plug -in disc 58, and spring 59 is arranged between lower plug -in disc 58 and hole plate 52. In the drawing, the top of casing 51 is integrally formed with cannula 514 through necked portion 513, and the cannula 514 is connected with the intermediate pipe 4.

[0020] The feature of the structure is that a T-shaped pipe is arranged in the middle of the catheter, and a middle pipe is connected to the side arm branch of the T-shaped pipe, and the middle pipe is connected to the collecting connector. The middle pipe is a flexible pipe, which can not limit the position and shape of the collecting connector during the collecting operation. In addition, the embodiment also provides a sealing effect and a simple collecting connector. The collecting connector has a hole plate, and the lower part of the hole plate is a guide ring accommodating a spring. A guide rod is inserted into the center of the hole plate, and the end of the guide rod is a lower plug disc. Under normal circumstances, the lower plug disc seals the collecting hole under the action of the spring, so that urine cannot leak out of the collecting hole.

[0021] When urine needs to be collected, the collecting pipe head is inserted into the collecting hole, the collecting connector contacts the lower plug disc, and the spring is compressed. Urine enters the guide ring from the hole plate, then enters the exchange cavity through the exchange hole of the side wall, and finally flows into the lower part of the lower plug disc through the exchange hole of the exchange cavity, and then finally flows out of the collecting hole, that is, introduced into the collecting pipe head, and finally introduced into the collecting bottle through the connected flexible pipe.

[0022] In the illustration, the bottom of the shell 51 protrudes downward and forms an inner ring 511, which supports the lower plug disc, and the center hole of the ring 511 is the collecting hole 53. The collecting hole 53 is provided with a reverse edge 512. The collecting pipe head is easily inserted.

[0023] As Figure 4 The structure of the collecting pipe head shown includes a hard drainage pipe 61, the middle part of which has a shielding ring 62, and the head part of the drainage pipe 61 has an inlet hole 63 in the side wall. When the head part of the drainage pipe pushes the lower plug disc, urine finally enters the drainage pipe through the inlet hole, and finally flows out through the flexible pipe 7. In this structure, the shielding ring facilitates the insertion of the collecting pipe head and can also shield the urine that may leak during the insertion and removal operation, avoiding hand pollution.

[0024] Therefore, when the urine is collected, the collecting pipe head is directly inserted into the collecting hole, the collecting pipe head is connected with a flexible pipe, and the urine is introduced into the collecting bottle through the flexible pipe, and then taken out after a period of time. The product has the advantages of simple operation, good sealing effect, no need to pull out the catheter, and no urine pollution.

[0025] In addition, as a preferred structure, the guide rod 57 is located above the orifice plate 52 and a top plug disc 510, and a transition cavity 515 with a larger diameter than the top plug disc is located above the top plug disc 510 in the shell 51. This structure forms a two-stage sealing structure, the top plug disc seals the orifice plate, and when the lower plug disc is pushed, the top plug disc moves upward synchronously and enters the transition cavity, and since the diameter of the transition cavity is larger than that of the top plug disc, urine enters the orifice plate from the periphery of the top plug disc, and when released, the top plug disc is reset under the action of the spring force to seal the orifice plate. Therefore, by means of the two-stage sealing arrangement, the sealing effect can be improved.

[0026] The above merely describes preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
