Abstract
The utility model relates to a catheter junction valve which belongs to medical devices. The catheter junction valve comprises a plastic three-way valve; a tapered plug which is adapted to an orifice of the catheter is arranged on a lower orifice of the plastic three-way valve; an upper orifice of a plastic three-way tube is a tapered plug the same as the orifice of the catheter and the other upper orifice of the plastic three-way tube is a straight plug adapted to an injection head of an injector; and a sealing cover is assembled on the straight plug. The catheter junction valve is simple in structure and convenient for use and operation and has the effect of preventing leakage and infection.
Description
Technical field
This utility model relates to a kind of catheter and connects valve, belongs to medical equipment.
Background technology
Catheter is clinical disposable commonly used, and the plugging phenomenon is often arranged when the patient uses, and needs to use the syringe washing pipe; In addition, intravesical has hemorrhage or when infecting, also needs to carry out bladder irrigation with syringe or transfusion device.When washing pipe or flushing, urinary catheter need be separated with excrement tracting tube usually, link to each other with syringe or transfusion device then, because of both do not match, the gap is big, and leakage is easily wasted time and energy, and operation inconvenience easily causes and infects, pollutes bed surface.
The utility model content
The purpose of this utility model is to provide a kind of catheter to connect valve, and is simple in structure, uses easy to operately, and can prevent leakage, prevention infection, and the maintenance bed surface is clean and tidy, dry and comfortable.
Catheter described in the utility model connects valve, it is characterized in that having a plastic three-way valve, the lower nozzle of plastic three-way valve is provided with the cone-shaped plug that adapts with the catheter mouth of pipe, a upper orifice of three-way plastic tube is the tapered spigot identical with the drainage tube mouth of pipe, another upper orifice of three-way plastic tube is the straight shape socket that adapts with the injector to inject head, and straight shape socket is fitted with seal cover.
Seal cover is connected as a single entity with straight shape socket, uses more convenient.
During use, cone-shaped plug is inserted the catheter mouth of pipe, excrement tracting tube is inserted tapered spigot.Under the normal condition, the seal cover on the straight shape socket is in the tightening seal state that covers.When needing flushing, open seal cover, injector to inject head or transfusion device plug are inserted straight shape socket, carry out flushing operation, simple and convenient.And, can realize both tight contacts because straight shape socket and injector to inject head adapt, prevented leakage.
Compared with prior art, the utlity model has following advantage:
Simple in structure, use easy to operately, and can prevent leakage, prevention infection keeps bed surface clean and tidy, dry and comfortable, is beneficial to patient's rehabilitation.
Description of drawings
Fig. 1, this utility model one example structure sketch map.
Among the figure: 1, cone-shaped plug 2, three-way plastic tube 3, tapered spigot 4, straight shape socket 5, seal cover.
The specific embodiment
The utility model is described in further detail in conjunction with the foregoing description accompanying drawing.
As shown in the figure, catheter described in the utility model connects valve, one plastic three-way valve 2 is arranged, the lower nozzle of plastic three-way valve 2 is provided with the cone-shaped plug 1 that adapts with the catheter mouth of pipe, a upper orifice of three-way plastic tube 2 is the tapered spigot 3 identical with the drainage tube mouth of pipe, another upper orifice of three-way plastic tube 2 is the straight shape socket 4 that adapts with the injector to inject head, is fitted with seal cover 5 on the straight shape socket 4, and seal cover 5 is connected as a single entity with straight shape socket 4.
During use, cone-shaped plug 1 is inserted the catheter mouth of pipe, excrement tracting tube is inserted tapered spigot 3.When needing flushing, open seal cover 5, injector to inject head or transfusion device plug are inserted straight shape socket 4, can implement flushing.
Claims (2)
