[0024] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.
[0025] Such as Figure 1-4 As shown, the present invention provides a technical solution: a urinary catheter includes a composite glass catheter 18, the front end of the composite glass catheter 18 is provided with a catheter hole 1, and the composite glass catheter 18 The groove of the glass urinary catheter 18 is provided with an airbag 19 to wrap the composite glass urinary catheter 18, and the airbag 19 is connected to the manual inflator 3 through the air inlet pipe 2, and the end of the manual inflator 3 is provided with a unidirectional Plug 4, use the manual inflator 3 to inflate the airbag 3 through the intake pipe 2 to inflate it to a certain degree. The one-way plug 4 can prevent the gas in the airbag from leaking, and will not leak during use. Naturally deflate. Pull out the one-way plug 4 after use to deflate the airbag 3, which solves the problem of leakage of urine due to the gap between the catheter and the bladder muscle due to the absence of a fixed catheter. The middle part of the tube 16 is provided with a hose 5, one end of the hose 5 is interference-connected with a syringe 8, and the bottom end of the syringe 8 is fixedly connected with a base 7, and both sides of the syringe 8 below the base 7 are respectively The first movable shaft 20 and the second movable shaft 21 are fixedly connected, the first movable shaft 20 is fixedly connected with a first pressure telescopic rod 6, and the second movable shaft 21 is fixedly connected with a second pressure movable shaft 9, Close the first valve 10 and the second valve 17, pull the base 7 on the syringe 8 to evacuate the air in the urinary tube 16, and stretch to a certain extent. The first movable shaft 20 and the second movable shaft 21 extend the first pressure rod 6 and the second pressure telescopic rod 9 are pressed against the base 7 to fix its working state, and a low pressure is formed in the urination tube 16, which can well discharge the patient's urine and urine containing a little clot and necrotic tissue. The first pressure The telescopic rod 6 and the second pressure telescopic rod 9 have a certain pressure inside, and they will not easily retract when they are stretched. The second valve 17 is provided on the end of the urinary tube 16 near the composite glass catheter 18, so The other end of the urination tube (16) is fixedly connected to the urine storage bag 15 with a first valve 10, and a sealing rubber ring 11 is provided at the junction of the urine storage bag 15 and the urination tube 16 below the first valve 10. The urine storage bag 15 is marked with a scale 12, the lower right end of the urine storage bag 15 is provided with an excretion tube 13 and the other end of the excretion tube 13 is provided with a drain plug 14.
[0026] Before use, close the first valve 10 and the second valve 17, pull the base 7 on the syringe 8 to evacuate the air in the urinary tube 16 and stretch it to a certain extent to pass through the first movable shaft 20 and the second movable shaft 21. A pressure telescopic rod 6 and a second pressure telescopic rod 9 are pressed against the base 7 to fix their working state, and a low pressure is formed in the urination tube 16, which can well discharge the patient's urine and urine containing some clots and necrotic tissue , The first pressure telescopic rod 6 and the second pressure telescopic rod 9 have a certain pressure inside, they will not easily retract when they are stretched, and then insert the composite glass catheter 18 into the patient's body. At this time, use manual inflation The device 3 inflates the airbag 3 through the air intake pipe 2 to make it expand to a certain extent. The one-way plug 4 can prevent the air in the airbag from leaking, and will not naturally deflate when it is used. Pull out the one-way plug 4 to deflate the airbag 3, and then open the first valve 10 and the second valve 17, the urine can enter the composite glass catheter 18 into the urinary tube 16 through the catheter hole 1. Then enter the urine storage bag 15, which is made of transparent plastic material, which is convenient for medical staff to check. Finally, the urine can be discharged through the excretion tube 13 by opening the excretion plug 14.
[0027] In summary, the present invention provides manual inflator 3, air bag 19, syringe 8, first valve 10, second valve 17, urine bag 15, first pressure telescopic rod 6, second pressure telescopic rod 9, and base 7 Solve the problem of leakage of fluid and urine, inconvenience for medical staff to check the condition, and inability to help the patient to remove some clots and necrotic tissue in urine and urine through the catheter.
