Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0020] Such as figure 1 and figure 2 As shown, the schematic diagram of the structure of the urinary catheter of the present invention and the schematic diagram during use are provided respectively. Liquid collection end 11, telescopic hose 13, nylon guide wire 14; The head 1 shown is used to extend in the human bladder interior 17, has urination opening 9 and medicine outlet 10 on the head 1, and urination opening 9 can There are multiple, the urination port 9 is used to discharge the urine in the bladder, and medicine or flushing fluid can be injected into the bladder through the drug outlet 10 . The water bag 8 is arranged at the rear end of the head 1, and after the water bag 8 is inflated, it functions to limit the head 1 inside the bladder.

[0021] The shown tail part 2 is provided with a medicine injection port 3, a urine outlet 4 and a wate...

Abstract

The invention discloses a catheter, comprising a head, a tail, a medicine injection pipe, a water injection pipe and a water bag, wherein a urination port and a medicine outlet are formed in the head; a medicine injection port, a urine outlet and a water injection port are formed in the tail. The catheter is characterized in that a urination channel which is communicated with the urination port and the urine outlet is formed among the medicine injection pipe and the water injection pipe and the urethral canal wall of a human body; a urine collection end is arranged on one end close to the tail, and is fixed on the tail through a flexible hose; the water injection port is communicated with the inner cavity of the water bag through the water injection pipe. According to the catheter, the flushing effect on the urethral canal is realized when a patient urinates, pathogenic microorganisms are prevented from producing retrograde infection at the external urethral orifice, the occurrence of inflammation is avoided, the service life of the catheter is prolonged, the cross section area of the catheter is greatly reduced, the irritation to the urethral canal is small, and the discomfort of the patient is alleviated. The catheter has the advantages that the structure is novel, the beneficial effect is obvious, and the application and popularization are facilitated.

Description

technical field [0001] The present invention relates to a urinary catheter, in particular to a urinary catheter in which the urine discharged by a patient can flush the urethra. Background technique [0002] Urinary catheter is a pipeline made of natural rubber, silicone rubber or polyvinyl chloride (PVC). It can be inserted into the bladder through the urethra to drain urine. After the catheter is inserted into the bladder, there is a tube near the head of the catheter. The air bag (also called water bag) fixes the catheter in the bladder and should not come out, and the drainage tube is connected to the urine bag to collect urine. The traditional urinary catheter is basically to set a drug injection tube and a water injection tube in a rubber tube with a larger diameter, and the cavity in the rubber tube is used as a passage for urine to flow out. [0003] There are two major disadvantages in the traditional urinary catheter: (1) When using the traditional urinary ca...
