Abstract
The utility model relates to a three-way urine tube, wherein a flushing port of the three-way urine tube is fixedly connected with a joint; the joint comprises a first port and a second port, and the first port is fixed on a flushing port of the three-way urine pipe; an external thread used for being connected with the threaded output end of the precision infusion set is formed on the outer side of the second port; a frustum-shaped hollow channel is formed between the first port and the second port, and the diameter of the hollow channel is gradually reduced from the first port to the second port; the hollow channel is internally provided with a frustum-shaped plug, and the diameter of the plug is gradually reduced from the first end to the second end; a spring supporting the plug is arranged between the first end of the plug and the first port, and the plug moves towards the second port and closes the second port under the pushing of the spring, so that the joint is closed; when the plug is lifted, the plug is moved away from the second port, whereby the joint is opened.
Description
Technical Field
The utility model relates to a medical instrument especially relates to a three-way ureter.
Background
One path of the three-way urinary catheter is used for draining urine, the other path is used for inflating the saccule to fix the urinary catheter in the bladder of the patient and prevent the urinary catheter from dropping off, and the other path is used for flushing the urinary catheter by using normal saline. At present, the plug is taken down when the flushing port of the three-way urine pipe is flushed, and then the three-way urine pipe is connected with an injector or an infusion apparatus, and is plugged again after flushing. The removed plug may become contaminated and reinsertion into the irrigation port often results in urinary tract infection in the patient.
SUMMERY OF THE UTILITY MODEL
In view of the above problem, the present invention aims to provide a three-way urine tube with a fixed connection to the flushing port, which is automatically opened when connecting the infusion device, and automatically closed when taking off the infusion device without taking off the infusion device, thereby avoiding the infection caused by the external pollution.
The three-way urine pipe of the utility model is fixedly connected with a joint at the flushing port;
the joint comprises a first port and a second port, and the first port is fixed on a flushing port of the three-way urine pipe; an external thread used for being connected with the threaded output end of the precision infusion set is formed on the outer side of the second port; a frustum-shaped hollow channel is formed between the first port and the second port, and the diameter of the hollow channel is gradually reduced from the first port to the second port; the hollow channel is internally provided with a frustum-shaped plug, and the diameter of the plug is gradually reduced from the first end to the second end; a spring supporting the plug is arranged between the first end of the plug and the first port, and the plug moves towards the second port and closes the second port under the pushing of the spring, so that the joint is closed; when the plug is lifted, the plug is moved away from the second port, whereby the joint is opened.
Preferably, an inwardly directed boss is formed at the first port, and a spring is supported between the boss and the first end of the plug.
The connector which can be connected with the threaded output end of the precise infusion apparatus is arranged at the flushing port of the three-way urine tube, so that the three-way urine tube can be flushed by the precise infusion apparatus, after the three-way urine tube is flushed, the connector can be automatically closed after the infusion apparatus is taken down, the whole process is relatively closed, and the infection caused by external pollution is avoided.
Drawings
FIG. 1 is a schematic structural diagram of a conventional three-way urinary catheter;
FIG. 2 is a schematic structural view of the three-way urinary catheter of the present invention;
fig. 3 is a schematic diagram of the three-way urinary catheter of the present invention connected to the output end of the precision infusion device.
Detailed Description
The three-way urinary catheter is mainly used by a matched precise infusion apparatus, belongs to the prior art, and is widely used in clinic.
The three-way urinary catheter of the present invention will be described in detail with reference to the accompanying drawings.
The three-way urinary catheter of the utility model is fixedly connected with a joint 10 at the flushing port.
The fitting 10 includes a first port 13 and a second port 12. The first port 13 is fixed on the flushing port of the three-way urine pipe; an external thread 11 used for being connected with a thread output end 20 of a precision infusion set is formed on the outer side of the second port 12; a frustum-shaped hollow passage is formed between the first port 13 and the second port 12, and the diameter of the hollow passage is gradually reduced from the first port 13 to the second port 12; the hollow passage accommodates a frustum-shaped plug 16 therein, the plug 16 having a diameter that gradually decreases from a first end to a second end thereof; a spring 15 supporting the plug 16 is arranged between the first end of the plug 16 and the first port, and under the pushing of the spring 15, the plug 16 moves towards the second port 12 and closes the second port 12, so that the joint 10 is closed; when the plug 16 is lifted, the plug 15 is moved away from the second port 12, whereby the joint 10 is opened.
An inwardly directed boss 14 is formed at the first port 13 and a spring 15 is supported between the boss 14 and a first end of a plug 16.
When not in use, the fitting 10 of the flush port is closed as described in fig. 2.
When the precision infusion set is used, the threaded output end 20 of the precision infusion set is in threaded connection with the second port 12, the ejector rod 22 in the middle of the threaded output end 20 can eject the plug 16, as shown in fig. 3, at this time, the connector 10 is opened, and flushing liquid (physiological saline) in the pipeline 21 of the precision infusion set flows into the second port 12 of the connector 10 through the opening 23 in the threaded output end 20 and further flows into the flushing port of the three-way urine tube from the first port 13 through the hollow channel.
Claims (2)
1. A three-way urine pipe is characterized in that: a joint is fixedly connected with the flushing port of the flushing pipe;
