[0035] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0036] Reference Figure 1-7 A urinary catheter for urology comprises a detachably connected insertion tube 1 and an extension tube 2; wherein the insertion tube 1 is of a shorter length and is directly inserted into the patient's urethra, and the extension tube 2 is of a longer length to divert and collect urine; the two are detachably connected, and their parts can be replaced with different specifications according to the actual patient situation.

[0037] A lubricating sleeve 3 is sleeved on the outside of the insertion tube 1, and the insertion tube 1 before being inserted into the urethra is coated with lubricating oil, and the insertion tube 1 can also be preliminarily cleaned after being pulled out.

[0038] like Figure 1-4 As shown; the lubricating sleeve 3 is an ellipsoidal structure, forming a cavity inside thereof; at the same time, the upper and lower ends of the lubricating sleeve 3 are respectively provided with an upper pipe opening 31 and a lower pipe opening 32 communicating with the cavity for filling or discharging.

[0039] When in use, the lubricating liquid is filled into the interior thereof through the upper tube opening 31; during the process of inserting into the urethra, the insertion tube 1 passes through the lubricating sleeve 3 so that its surface is coated with the lubricating liquid, which makes it easier to insert into the patient's urethra and reduces the patient's pain; in addition, after the insertion is completed, the lubricating liquid can be discharged through the lower tube opening 32, and clean water can be flushed in to clean the inner cavity of the lubricating sleeve 3.

[0040] Furthermore, before being pulled out, disinfectant is filled into the lubricating sleeve 3, and the pulled out insertion tube 1 is simply disinfected and cleaned.

[0041] In some embodiments, the front and rear ends of the lubricating sleeve 3 are respectively provided with a front ring 33 and a rear ring 34 with an inner diameter slightly larger than the insertion tube 1, so that it extends forward and backward for a certain distance to reduce the outflow of lubricating liquid; at the same time, it is better fitted on the insertion tube 1 and is more stable.

[0042] In some embodiments, a reducing rubber ring 35 whose inner diameter gradually decreases toward the rear is disposed at the rear end of the rear circular ring 34 .

[0043] like Figure 3 , 4 As shown; the reducing rubber ring 35 fits tightly with the insertion tube 1 to prevent the liquid from flowing out of the rear end; and during the removal operation, the insertion tube 1 is reduced to reduce the amount of disinfectant brought out.

[0044] In some embodiments, a silicone cover 4 is mounted on the outside of the front ring 33 .

[0045] Among them, the silicone cover 4 can block the splashing and the like generated during the insertion and removal process; it can also be attached to the vulva of the female patient after insertion according to needs, using the viscosity of the silicone to provide certain shielding and protection, and better prevent the insertion tube 1 from moving and falling out.

[0046] It should be noted that the silicone cover 4 is usually sleeved on the front ring 33 ; when in use, it can maintain this form, or be removed and directly sleeved on the insertion tube 1 .

[0047] In some embodiments, a collar 41 is disposed at the rear end of the silicone cover 4, and an inflatable ring 42 is disposed on the inner side of the collar 41; the inflatable ring 42 is elastically expandable to keep it firmly mounted or to be removed.

[0048] It is understandable that the inflation ring 42 can be directly set as a sealing ring, and its elastic deformation can be used to simultaneously adapt to the outer diameters of the front ring 33 and the insertion tube 1; and an inflation and deflation port can also be set to adjust it.

[0049] In some embodiments, the front end of the insertion tube 1 is provided with an elliptical head 5 to facilitate insertion into the urethra.

[0050] Correspondingly, the oval head 5 is provided with surrounding openings for urine to pass through.

[0051] In some embodiments, the front end of the extension tube 2 is provided with an airbag 6, and the rear end of the insertion tube 1 is inserted and connected to the upper end of the airbag 6; accordingly, an exhaust port 61 and a sealing cap are provided above the airbag 6.

[0052] When in use, the air bag 6 can assist in extracting urine.

[0053] The arrangement of the airbag 6 is prior art, such as the airbag structure on an infusion tube, and will not be described in detail here.

[0054] In some embodiments, the tail end of the extension tube 2 is connected to a micro pump 7 for electric pumping.

[0055] In some embodiments, the tail end of the extension tube 2 or the outlet end of the micro pump 7 is connected to a urine collection bucket or a urine collection bag.

[0056] Furthermore, the urine collecting bucket or the urine collecting bag is provided with a capacity scale line, so that the amount of urine catheterization can be directly checked.

[0057] When the utility model is used, according to the patient's condition, the insertion tube 1 and the extension tube 2 of appropriate specifications and lengths are matched accordingly, and after connecting them, the extension tube 2 is connected to the urine collection bucket or urine collection bag; then, the insertion tube 1 is inserted into the lubricating sleeve 3, and the lubricating liquid is filled into the lubricating sleeve 3; after the insertion tube 1 is drawn out from the front end of the lubricating sleeve 3, it is coated with lubricating liquid and inserted into the patient's urethra; after being inserted into place, the silicone cover 4 is attached to the female vulva (not for men, only as a protection against splashing); during the catheterization process, the air bag 6 is selected for assistance according to the actual situation, or the micro pump 7 is used for extraction; after the catheterization is completed, the disinfectant is filled into the lubricating sleeve 3, and the pulled-out insertion tube 1 is simply disinfected and cleaned.

[0058] In the utility model, the insertion tube 1 and the extension tube 2 are arranged in a detachable connection form, and different specifications of parts thereof can be replaced according to the actual patient conditions; a lubricating sleeve 3 is arranged to coat the insertion tube 1 before insertion into the urethra with lubricating oil, and the pulled-out insertion tube 1 can also be preliminarily cleaned; a silicone cover 4 is arranged to avoid splashing and the like generated during insertion and removal, and can also be attached to the vulva of a female patient to provide certain shielding and protection; an air bag 6 and a micro pump 7 are used to assist in extracting urine; a capacity scale line is arranged, and the amount of catheterization can be directly checked.
