Technical field

The utility model is related to water filling device in a kind of medicine equipment, more particularly to a kind of art for Flexible ureteroscope.

Background technology

With the maturation of Flexible ureteroscope technology, renal plevis pressure is excessive in current Flexible ureteroscope art has with postoperative complications Directly related property has become common recognition, it is to avoid the excessive secured premise for becoming Flexible ureteroscope art of renal plevis pressure in art, therefore need to be Carry out water flood operations in art to balance renal plevis pressure, water flood operations are also that Flexible ureteroscope art obtains the clear visual field and precisely operation Guarantee.

2 kinds of methods promising to water flood operations in Flexible ureteroscope art in current clinical position：1. irrigated using medical pressure Pump, but medical charging pump hydraulic pressure is larger, it is impossible to hydraulic pressure in accuracy controlling art, easily causes POI, bleeding etc. more concurrent Disease；2. artificial recharge is carried out by syringe, its advantage is that water consumption is few in art, can be accurate according to actual conditions in operator's art Control hydraulic pressure, reach can precise control hydraulic pressure avoid postoperative complication from can guarantee that surgical field of view again clearly, but artificial recharge At present still without special water filling apparatus, operator is more in clinical position voluntarily utilizes transfusion device or blood transfusion to method according to unit condition Device is reequiped, or using height Action of Gravity Field carry out height suspention perfusion, in practical operation have operation inconvenience, in art leak Water, needs frequently plug and aspirating syringe, and the deficiency for needing many people's cooperations.

Utility model content

The technical problems to be solved in the utility model is to provide water filling device in a kind of art for Flexible ureteroscope, passes through The circulation style of switching three-way valve, and with pressurization infusion device and push away the cooperating of water syringe, urine output can be simplified Water flood operations process in pipe soft lens art, saves manpower, and is easy to control water injection rate.

To achieve these goals, technical solution adopted in the utility model is：A kind of art for Flexible ureteroscope Middle water filling device, including three-way valve, the first interface of the three-way valve is described by water inlet pipe connection pressurization infusion device The built-in screen pack of water inlet pipe, the second interface connection of three-way valve pushes away water syringe, and the 3rd interface of three-way valve connects Waterpipe, outlet conduit is plugged together with the service aisle of Flexible ureteroscope and is tightly connected.

As a kind of optimal technical scheme of the present utility model, also include in its structure for fix the three-way valve and Push away the fixed mount of water syringe.

Used as a kind of optimal technical scheme of the present utility model, the pressurization infusion device includes infusion vessel and is enclosed within defeated Pressurizer on liquid container outer wall, infusion vessel is infusion bottle or infusion bag made by flexible plastic, and pressurizer is annular air-pocket.

Used as a kind of optimal technical scheme of the present utility model, the three-way valve is the Medical tee joint with switching switch Valve.

It is using the beneficial effect produced by above-mentioned technical proposal：Three-way valve of the present utility model allows hand over physiology The circulating direction of salt solution, first connects first interface and second interface simultaneously closes off the 3rd interface, and the infusion device that now pressurizes is automatic Supply water to push away water syringe, push away water syringe full of after water, connection second interface and the 3rd interface simultaneously close off first interface, Artificial control pushes away water syringe, and the physiological saline pushed away in water syringe is input to into the service aisle of Flexible ureteroscope, complete by Water filling is needed, simplifies water flood operations process, save manpower, and be easy to control water injection rate.

Description of the drawings

The utility model is described in further detail with reference to the accompanying drawings and detailed description.

Fig. 1 is overall structure diagram of the present utility model.

Fig. 2 is the sectional side elevation of the utility model pressurization infusion device.

In figure：1st, three-way valve 2, first interface 3, water inlet pipe 4, pressurization infusion device 5, screen pack 6, second Interface 7, push away water syringe 8, the 3rd interface 9, outlet conduit 10, Flexible ureteroscope 41, infusion vessel 42, pressurizer.

Specific embodiment

Referring to attached Fig. 1 and 2, the structure of one specific embodiment of the utility model includes three-way valve 1, the triple valve The first interface 2 of door 1 is by the connection pressurization infusion device 4 of water inlet pipe 3, the built-in screen pack 5 of the water inlet pipe 3, triple valve The connection of second interface 6 of door 1 pushes away water syringe 7, the connection outlet conduit 9 of the 3rd interface 8 of three-way valve 1, outlet conduit 9 with it is defeated The service aisle of urinary catheter soft lens 10 is plugged together and is tightly connected.

Also include the fixed mount for fixing the three-way valve 1 He push away water syringe 7 in its structure.Fixed mount can be protected Hold and push away stability when water syringe 7 pushes away water.The three-way valve 1 is the Medical tee joint valve with switching switch.

Individually referring to Fig. 2, the pressurization infusion device 4 includes infusion vessel 41 and is enclosed within adding on the outer wall of infusion vessel 41 Depressor 42, infusion vessel 41 is infusion bottle or infusion bag made by flexible plastic, and pressurizer 42 is annular air-pocket.Pressurizer 42 is to defeated Liquid container 41 applies pressure, and the physiological saline press-in in infusion vessel 41 is pushed away into water syringe 7.

Operation principle of the present utility model is：Switched by the switching of three-way valve 1, first connect first interface 2 and second Interface 6, simultaneously closes off the 3rd interface 8, and now pressurizeing infusion device 4, water inlet pipe 3 and pushes away water syringe 7 and connect, and pressurizes defeated Dispensing device 4 supplies water to push away water syringe 7 automatically, pushes away water syringe 7 full of after water, connects the interface 8 of second interface 6 and the 3rd, First interface 2 is simultaneously closed off, the service aisle connection of water syringe 7, outlet conduit 9 and Flexible ureteroscope 10, people is now pushed away Industry control system pushes away water syringe 7, and the physiological saline pushed away in water syringe 7 is input to into the service aisle of Flexible ureteroscope 10, this reality With the new operating process for simplifying water filling, it is to avoid plug and suction repeatedly pushes away water syringe 7, manpower is saved, and be easy to control Water injection rate processed.
