Detailed Description
Referring to fig. 1 to 11, a urinary catheter urination switch comprises a urination switch 1 and a fixing device 2, wherein the urination switch 1 is connected with a urinary catheter 3, the urination switch 1 is detachably arranged on the fixing device 2, and the fixing device 2 is fixed on the thigh of a patient;
the urination switch 1 comprises an outer shell 11 and an inner core 12, wherein the outer shell 11 is sleeved on the inner core 12, and the outer shell 11 can rotate on the inner core 12;
the shell 11 is provided with a clamping groove 111, a convex block 112, a round hole 113 and a urine outlet 114;
the inner core 12 is symmetrically provided with a spring plunger 121 and a stopper 122, the inner core 12 is also internally provided with a urination channel 123 and a spring plunger mounting groove 124, and the spring plunger 121 is slidably mounted in the spring plunger mounting groove 124;
the spring plunger 121 comprises a plunger 1211 and a return spring 1212, the plunger 1211 is slidably mounted inside the spring plunger mounting groove 124, and the return spring 1212 is arranged between the bottom of the spring plunger mounting groove 124 and the plunger 1211;
the end of the plunger 1211, which is exposed out of the spring plunger mounting groove 124, is a ball head, and the diameter of the ball head is smaller than that of the round hole 113;
the fixing device 2 comprises an elastic band 21 and a buckle 22, and the housing 11 can be clamped into the buckle 22 through a clamping groove 111.
The utility model discloses a theory of operation and process:
referring to fig. 1 to 11, in use, when the urination switch 1 is connected with the urinary catheter 3 by a medical staff, the fixing device 2 is fixed on the thigh of a patient through the elastic bandage 21, the position of the fixing device 2 on the thigh is adjusted, the outer shell 11 is clamped into the buckle 22 through the clamping groove 111, the position of the urination switch 1 is fixed, inconvenience is not brought to the patient due to random play, when the urination switch 1 is in a non-urination state, the outer shell 11 is fixed by the right spring plunger 121, the urination port 114 on the outer shell 11 is not connected with the urination passage 123 in the inner core 12, urine is prevented from flowing out, when the patient needs to urinate, the outer shell 11 is rotated 180 degrees around the axis of the inner core 12, at the moment, the outer shell 11 is fixed by the left spring plunger 121, the urination port 114 on the outer shell 11 is connected with the urination passage 123 in the inner core 12, urine flows out, after the patient urinates, the outer shell 11 is reversely rotated to the initial position, the stop catch 122 on the inner core 12 cooperates with the protrusion 112 on the outer shell 11 to limit the rotation of the outer shell 11, and prevent the outer shell 11 from over-rotating, so that the urine outlet 114 on the outer shell 11 and the urine outlet channel 123 in the inner core 12 cannot be aligned, thereby affecting the discharge of urine.
