Description
Technical field
This utility model relates to fujinon electronic video endoscope technical field, is specifically related to the joint design at a kind of fujinon electronic video endoscope pincers road junction and endoscope's water sending device.
Background technology
Existing endoscope water sending device pincers road joint is tee T form, mainly by major joint, gland nut, pincers road junction with send water interface to form.Gland nut is arranged on outside one end of major joint for connecting endoscope, connects one end of gland nut built with sealing gasket at major joint, it is achieved pincers road joint seals with the operation handle of endoscope.The other end of major joint is outer to be inserted from pincers road junction equipped with pincers road junction for connection clamp class adnexa, such as biopsy forceps, pincers class adnexa, enters back into the pincers road of endoscopic procedure handle after major joint.Send on the middle part sidewall that water interface is arranged on major joint, by sending water interface to endoscope's inner water-supply.This tee T achieves while sending the Fujian such as water and plug in biopsy forceps and carries out, and saves patient's review time, improves doctor and check efficiency.
But, in use, occur in that problems with:
(1) when water pump send water, inserting and clogged to prevent water from leaking from pincers road junction by a rubber stopper at the pincers road junction of adnexa, but when water pump send water, pressure is big, the pressure that rubber stopper produces when easily being sent water is washed open, thus causes sending water failure, affects doctor's operation.
(2) when doctor inflates in patient body, in inflation descendant's body, air pressure is high, the most just has the mucus in the intestines and stomach, digest etc. to feed in water pipe by pincers road joint back-pressure, pollutes flow pipe, affect doctor and use.
Utility model content
This utility model aims to provide a kind of endoscope water sending device pincers road joint, and in when preventing water pump from sending water, leakage, and patient body occurs in pincers road junction, during inflation, the liquid reflux of harmonization of the stomach intestinal feeds water pipe.
For this, the technical scheme that this utility model is used is: a kind of endoscope water sending device pincers road joint, including major joint, gland nut, clamp road junction and send water interface, described gland nut is arranged on outside one end of major joint for connecting endoscope, and connect one end of gland nut built with sealing shroud at major joint, the other end of described major joint is outer is used for connection clamp class adnexa equipped with pincers road junction, on the described middle part sidewall sending water interface to be arranged on major joint, the one end at described major joint connection clamp road junction is built with the first valve core case, duck-beak type check valve and pincers road joint sealing pad it is sequentially installed with in the first valve core case, and be locked in the inner chamber of the first valve core case by locking nut, the diameter of bore of described pincers road joint sealing pad is less than the diameter of connection clamp class adnexa；Described send water interface to be arranged on the middle part sidewall of major joint by the second valve core case, the inner chamber of the second valve core case is provided with duck-beak type check valve.
Preferred as such scheme, described gland nut is tightened by double thread with major joint, the outer end extruding laminating of the closing in portion, outer end of gland nut and sealing gasket；Described first valve core case is placed in major joint, and the outboard end of the first valve core case is blocked by pincers road junction, and is provided with sealing ring between the first valve core case and major joint, prevents the local spilling that water coordinates with major joint from the first valve core case；Described major joint and pincers road junction, major joint and the second valve core case, the second valve core case and send water the interface threaded or button bit viscose glue of employing or plastic ultrasonic to weld.Optimize structure to arrange, make compact overall structure, and guarantee to seal.
Further, sending water interface described in is Rule cone joint.Correspondingly, flow pipe one end is outer cone joint, be ensure that by female Luer connection and send being tightly connected of water seam.
The beneficial effects of the utility model:
(1) increasing by the second valve core case on water interface for installing duck-beak type check valve sending, when doctor gives internal inflation, the liquid reflux being controlled harmonization of the stomach intestinal by duck-beak type check valve feeds water pipe；
(2) in the one end at major joint connection clamp road junction, increase by the first valve core case for installing duck-beak type check valve and pincers road joint sealing pad, and locked by locking nut, when water pump send water and do not uses adnexa, the duck-beak type check valve in major joint plays the effect from the leakage of pincers road junction of the cut-off water；When water pump send water and pincers road junction has adnexa to insert, adnexa makes the duck-beak type check valve in major joint open, at this moment the function sealed seals by pincers road joint sealing pad, diameter of bore is less than the diameter of connection clamp class adnexa, adnexa is formed with pincers road joint sealing pad extruding and seals, thus reaches adnexa and the function sent water function and use simultaneously.
