Description

Technical Field

[0001] The present invention relates to the technical field of urology, and in particular to a urinary catheter flushing device for urology. Background Art

[0002] A urinary catheter is a tube that is inserted into the bladder through the urethra to drain urine. It is a tube made of natural rubber, silicone rubber or polyvinyl chloride (PVC) that can be inserted into the bladder through the urethra to drain urine. After the urinary catheter is inserted into the bladder, there is an air bag near the tip of the catheter to fix the catheter in the bladder and prevent it from coming out. The drainage tube is connected to a urine bag to collect urine.

[0031] In the present invention, two mutually connected heating mechanisms 9 are provided, and the middle pipe of the infusion tube 8 is coiled between the two heating mechanisms 9. When the flushing liquid in the infusion tube 8 flows through the heating mechanism 9, the flushing liquid is heated to a temperature consistent with the patient's body temperature, and a flushing catheter 10 that can be inserted into the inside of the drainage tube 12 is provided. After the drainage tube 12 is inserted into the patient's body, when it is necessary to flush the patient's bladder, the heating mechanism 9 is heated in advance, and then the flushing catheter 10 is inserted along the drainage tube 12, and the outlet of the infusion tube 8 is connected to the flushing catheter 10, and the flushing liquid is introduced into the patient's bladder. The flushing catheter 10 is inserted into the drainage tube 12 to realize the diversion of the flushing liquid and urine, avoiding the backwashing of urine into the bladder to cause infection, and the flushing catheter 10 moves inside the drainage tube 12 to avoid irritation to the patient's urethra during the insertion and removal of the flushing catheter 10. The diversion of the flushing liquid and urine can realize the flushing and replacement of the patient's bladder, which is more conducive to the flushing operation of the patient's bladder and improves the discharge effect of secretions in the bladder or postoperative thrombus.

[0032] As a further solution in the present invention, the heating mechanism 9 includes a shell 91 and a water bag 92 arranged inside the shell 91, a heater 95 and a temperature sensor are arranged in the water bag 92, and a magnetic lock 93 that is magnetically attracted to each other is fixedly installed on the side of the shell 91.

[0038] As a further solution in the present invention, an annular cavity 126 is provided at the front end of the main body 121, and an elastic hole with trumpet-shaped structures at both ends is provided in the middle of the annular cavity 126. An extrusion head with a hemispherical structure is provided at the front end of the flushing main body 101. In the present invention, when the flushing catheter 10 is inserted into the drainage tube 12, the deformation of the supporting spring sheet 104 is relied on to keep the extrusion head at the front end of the flushing main body 101 consistent with the axis of the drainage tube 12. The extrusion head squeezes the annular cavity 126 at the front end of the main body 121, and the supporting spring sheet 104 is used to cooperate with the inner side of the annular cavity 126 for elastic engagement, and the extrusion head of the flushing main body 101 is fixed, thereby separating the flushing liquid outlet from the urine drainage hole, thereby improving the flushing effect on the patient's bladder.

[0039] As a further solution in the present invention, a plurality of elastic columns 105 are provided in the middle section of the flushing main pipe 101, and the elastic columns 105 are distributed in a spiral shape. In the present invention, when the flushing main pipe 101 is inserted into the drainage tube 12, the elastic columns 105 located on the outside of the flushing main pipe 101 are obliquely deformed inside the drainage tube 12, and a plurality of V-shaped supports are formed between the flushing main pipe 101 and the drainage tube 12 to maintain the smoothness of the gap between the flushing main pipe 101 and the drainage tube 12. At the same time, when the patient's body position moves, radial displacement is generated between the flushing main pipe 101 and the main body 121, and the movement of the elastic columns 105 is used to prevent thrombus and the like from staying in the drainage tube 12. When the flushing main pipe 101 is pulled out, the elastic columns 105 and the supporting springs 104 effectively clean the inner wall of the drainage tube 12 to prevent bladder secretions, thrombus and the like from staying in the drainage tube 12.

[0040] As a further solution in the present invention, the sealing mechanism 11 includes a sealing plug 111 inserted into the flushing guide tube 125, and a plurality of annularly distributed fastening membrane flaps 112 are provided at the upper end of the sealing plug 111, and a sealing ring 113 is screwed on the outer side of the fastening membrane flap 112, and a convex ring portion 102 adapted to the end of the fastening membrane flap 112 is provided on the outer side of the flushing main pipe 101. In the present invention, the flushing catheter 10 is inserted into the interior of the drainage tube 12, and the front end of the flushing catheter 10 is restrained and limited by the supporting spring sheet 104, and the rear end of the flushing catheter 10 is limited by wrapping the convex ring portion 102 with the fastening membrane flap 112, thereby constraining the two ends of the flushing catheter 10 in the drainage tube 12 to avoid loosening and displacement during flushing and maintain the direction of the flushing liquid.

[0041] When in use, the middle pipe of the infusion tube 8 is coiled between the two heating mechanisms 9. When the flushing liquid in the infusion tube 8 flows through the heating mechanism 9, the flushing liquid is heated to a temperature consistent with the patient's body temperature, and a flushing catheter 10 that can be inserted into the drainage tube 12 is provided. After the drainage tube 12 is inserted into the patient's body, when the patient's bladder needs to be flushed, the heating mechanism 9 is preheated, and then the flushing catheter 10 is inserted along the drainage tube 12, and the outlet of the infusion tube 8 is connected to the flushing catheter 10, and the flushing liquid is introduced into the patient's bladder. The flushing liquid is heated and kept warm by the heating mechanism 9 to reduce the stimulation of the flushing liquid to the patient's bladder. Secondly, the flushing catheter 10 is inserted into the drainage tube 12 to realize the diversion of the flushing liquid and urine to avoid the backwashing of urine into the bladder to cause infection, and the flushing catheter 10 moves inside the drainage tube 12 to avoid irritation to the patient's urethra during the insertion and removal of the flushing catheter 10. The diversion of the flushing liquid and urine can realize the flushing and replacement of the patient's bladder.
