Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of urology surgery, in particular to a urinary catheter flushing device for urology surgery. Background Art
[0002] A urinary catheter is a tube inserted through the urethra into the bladder to drain urine. Made of natural rubber, silicone rubber, or polyvinyl chloride (PVC), it is inserted through the urethra into the bladder to drain urine. Once inserted, a balloon near the tip of the catheter secures the catheter in place, preventing it from coming out. The catheter is then connected to a urine bag to collect urine.
[0003] When patients have urinary tract infections or surgery-related care, a catheter is used to drain urine from the bladder. During the care process, the bladder and catheter often need to be flushed with normal saline to flush out secretions in the bladder, or thrombolytic drugs are used to dissolve blood clots that appear in the bladder after surgery. In the current medical stage, when urology medical staff drain urine and flush the bladder for patients, the flushing fluid and urine drainage are through the same pipe. During the flushing process, the urine in the catheter is backflushed into the bladder, which is prone to cross-infection.

[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 interior 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 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. The heating mechanism 9 is used to heat and keep the flushing liquid in the patient's bladder to reduce the stimulation of the flushing liquid on 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, avoiding the backflushing of urine into the bladder to cause infection, and the flushing catheter 10 moves inside the drainage tube 12, avoiding stimulation 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 provided 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. In the present invention, when flushing the urine catheter, the heater 95 is used to heat the liquid in the water bag 92, and then the infusion tube 8 is clamped between the two hot water bags 92, and the elasticity of the water bag 92 is used to cling to the outer wall of the infusion tube 8, and then the hot water bag 92 is used to perform heat treatment on the flushing liquid, and the flushing liquid is heated to the same temperature as the patient's body temperature, thereby effectively reducing the stimulation of the flushing liquid to the patient's bladder.
[0033] As a further solution in the present invention, the top and bottom of one shell 91 are provided with a U-shaped elastic clip 94, and the outer surface of the water bag 92 is provided with an S-shaped guide groove. In the present invention, when the two heating mechanisms 9 are unfolded, the middle section of the infusion tube 8 is respectively fixed in the elastic clip 94, and the infusion tube 8 is bent and arranged along the direction of the guide groove, thereby increasing the heat exchange area between the water bag 92 and the flushing liquid.

When the infusion tube 8 is fixed and the heating mechanism 9 is closed, the damping piston rod 32 slowly moves upward under the action of the tension spring 33, so that the water bags 92 on both sides expand synchronously, thereby tightly wrapping the infusion tube 8 and changing the pressure as the water temperature in the water bag 92 changes, thereby enhancing the stability of the heating and insulation of the flushing fluid.
[0035] As a further solution in the present invention, a guide bracket 2 is fixedly installed on the top of the support seat 1, and the outer wall of the pedal 34 is slidably connected to the guide bracket 2. In the present invention, the setting of the guide bracket 2 limits the movement of the pedal 34, avoiding jamming when medical staff step on it, and enhancing the convenience of operating the liquid storage mechanism 3.
[0036] As a further solution in the present invention, the drainage tube 12 includes a main body 121 and a limiting bag 122 arranged on the outer side of the main body 121.

In the present invention, the flushing main pipe 101 is inserted into the drainage tube 12 along the direction of the flushing guide tube 125, and the two ends of the supporting spring 104 contact the inner wall of the drainage tube 12 to produce a C-shaped deformation, thereby keeping the pipe mouth of the flushing main pipe 101 in the center position of the drainage tube 12 and moving forward, and urine drainage holes are reserved at both ends of the supporting spring 104 to facilitate the insertion operation of the flushing catheter 10.
[0038] As a further solution in the present invention, an annular cavity 126 is provided at the front end position 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 position 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 104 is relied upon 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 position of the main body 121, and the supporting spring 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 shrapnel 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 the upper end of the sealing plug 111 is provided with a plurality of annularly distributed fastening membrane flaps 112, and the outer side of the fastening membrane flap 112 is screwed with a sealing ring 113, and the outer side of the flushing main pipe 101 is provided with a convex ring portion 102 adapted to the end of the fastening membrane flap 112. In the present invention, the flushing catheter 10 is inserted into the drainage tube 12, and the front end of the flushing catheter 10 is restrained and limited by the supporting spring piece 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 the flushing process 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 heating mechanism 9 is used to heat and keep the flushing liquid warm to reduce the irritation of the flushing liquid to the patient's bladder area. Secondly, the flushing catheter 10 is inserted into the drainage tube 12 to realize the diversion of the flushing liquid and urine, avoiding the backflushing of urine into the bladder to cause infection, and the flushing catheter 10 moves inside the drainage tube 12, avoiding irritation to the patient's urethra during the insertion and removal of the flushing catheter 10.
