Problems solved by technology

[0002] The existing urine collection bag is directly connected to the drainage catheter, and the doctor directly punctures the tail end of the drainage catheter with a syringe needle during the operation, which has the following disadvantages: 1. Repeated punctures cause damage to the drainage catheter; 2. It is easy to puncture the drainage catheter Water sac, causing tube detachment; 3. Syringe injection and infusion set dripping liquid, causing liquid medicine to leak out; 4. Needle falling off and stabbing the patient

Embodiment Construction

[0017] A disposable urinary catheter connector for bladder irrigation, see attached figure 1 As shown, urine collection bag 1, connecting pipe 2, installation joint 2-1, drainage catheter 3, three-way valve 4, one end 4-1, the other end 4-2, third end 4-3, plastic connecting pipe 5 .

[0018] In this embodiment, the drainage catheter 3 is connected to the connecting pipe 2 through a three-way valve 4 . Preferably: one end 4-1 of the three-way valve 4 is connected to the drainage catheter 3, the other end 4-2 is connected to the connecting pipe 2, and the third end 4-3 is connected to the drug injection tube or directly injects the drug solution into the tube through a needle. In the valve hole of the third end 4-3. If the third end does not need to inject medicine, the third end 4-3 can also be connected with a diversion tube, which is used to divert the urine to the urine collection bag while diverting it into the diversion tube, and then the other end of the diversion tube...

Abstract

The invention relates to a medical irrigation and washing device, in particular to a disposable urinary catheter connector for intravesical instillation and an application thereof. The invention comprises a drainage urinary catheter and a connecting tube, wherein the drainage urinary catheter and the connecting tube are connected through a three-way valve. Compared with the prior art, the structure can smoothly inject drugs into the drainage catheter through the connection of the three-way valve. The application of disposable urinary catheter connector for intravesical instillation is carriedout according to the following steps: when three ports of three-way valve are communicated with each other or with each other, drugs and liquids are injected into the body or drained out of the body according to the needs of treatment and nursing care.

Description

technical field [0001] The invention relates to a medical lavage device, in particular to a disposable catheter connector for bladder irrigation and its application. Background technique [0002] The existing urine collection bag is directly connected to the drainage catheter, and the doctor directly punctures the tail end of the drainage catheter with a syringe needle during the operation, which has the following disadvantages: 1. Repeated punctures cause damage to the drainage catheter; 2. It is easy to puncture the drainage catheter The water bag causes the tube to come off; 3. The injection of the syringe and the dripping of the infusion set cause the liquid to leak out; 4. The needle falls off and stabs the patient. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a bladder perfusion disposable urinary catheter connector and its application. [0004] The present invention adopts follo...
