Detailed Description

The following describes the embodiments of the present invention in further detail with reference to the accompanying drawings.

By giving of fig. 1 to 4, barrel 1 towards the back including axial and opening around including, the coaxial stand pipe 2 rather than inside intercommunication that is equipped with of 1 front end of barrel, 1 front end of barrel is equipped with two dead levers 3 of arranging along left right direction, it has can with stand pipe 2 contact and curved clamp plate 4 to articulate on the dead lever 3, two clamp plate 4 arcs are relative, the coaxial annular plate 5 that is equipped with of 1 front end of barrel, clamp plate 4 is located between annular plate 5 and the stand pipe 2, set up two arc walls 6 with clamp plate 4 one-to-one on the annular plate 5, two arc wall 6 openings are relative, sliding connection has slider 7 in the arc wall 6, the looks remote site of two slider 7 is connected rather than clamp plate 4 of corresponding side through connecting rod 8 is articulated respectively, the coaxial rubber buffer 9 that is equipped with of rear side in the barrel 1, coaxial venthole 10 that link up around seting up is seted up on the rubber buffer.

In order to facilitate the two sliding blocks 7 to slide simultaneously, the outer side of the annular plate 5 is provided with an annular groove 11 with an outward opening and communicated with the arc-shaped groove 6, an auxiliary ring 12 is rotatably connected in the annular groove 11, and the back ends of the two sliding blocks 7 are fixedly connected with the auxiliary ring 12.

In order to facilitate the rotation of the auxiliary ring 12 and the positioning thereof, the front side of the annular plate 5 is provided with a limiting block 13 in the front-back direction, the auxiliary ring 12 is connected with a pushing block 14 in an inverted U shape in a sliding way, the pushing block can be clamped on the limiting block 13, and a tension spring 15 is arranged between the arc-shaped groove 6 and the sliding block 7.

In order to better clamp the gastric tube, the opposite surfaces of the two clamping plates 4 are respectively provided with a clamping groove 16 with the same shape as the two clamping plates, and the outer edge surface of the guide tube 2 is coaxially provided with an elastic ring 17 which can be inserted into the clamping groove 16.

In order to facilitate better air exhaust of the air outlet 10 and avoid overflow of drainage liquid, an air exhaust needle 18 is coaxially fixed in the air outlet 10, the rear end of the air exhaust needle 18 extends out of the air outlet 10, a connecting ring is coaxially arranged at the front end of the rubber plug 9, and a water-blocking and air-permeable membrane 19 is coaxially arranged in the connecting ring.

In order to facilitate the examination of the volume of the drainage liquid, the outer side of the barrel body 1 is provided with a plurality of scale marks 20 uniformly distributed along the front-back direction.

When the utility model is used, the push block 14 is pushed backwards at first, so that the push block 14 is not clamped on the limiting block 13 any more, at the moment, under the action of the tension spring 15, the tension spring 15 drives the slide block 7 to rotate clockwise along the arc-shaped groove 6, the slide block 7 pulls the clamping plate 4 to swing back to back along the fixed rod 3 through the connecting rod 8, so that the clamping plate 4 is not clamped on the guide pipe 2 any more, the elastic ring 17 is not clamped in the clamping groove 16 any more, and meanwhile, the slide block 7 drives the auxiliary ring 12 to rotate along the annular groove 11;

when the gastrointestinal atmospheric pressure reduction of a patient is needed, firstly, the stomach tube is sleeved on the guide tube 2, meanwhile, the elastic ring 17 is covered by the stomach tube, then the auxiliary ring 12 is rotated anticlockwise, the auxiliary ring 12 drives the slide block 7 to rotate anticlockwise along the arc-shaped groove 6, the tension spring 15 is stretched, the slide block 7 pushes the clamping plate 4 to swing relatively along the fixed rod 3 through the connecting rod 8, so that the clamping plate 4 extrudes the stomach tube, meanwhile, the elastic ring 17 is arranged in the clamping groove 16, the stomach tube can be fixed more firmly, better air tightness can be achieved, drainage liquid overflow is avoided, when the push block 14 rotates to be in the same straight line with the limiting block 13, the push block 14 is pushed forwards, the push block 14 is clamped on the limiting block 13, the clamping plate 4 can better extrude the stomach tube, meanwhile, the exhaust needle 18 is arranged, the gastrointestinal atmospheric pressure reduction of the patient can be effectively carried out, and the damage to the stomach, the water-blocking and air-permeable membrane 19 is arranged, so that the drainage liquid can be prevented from overflowing through the exhaust needle 18, and the scale marks 20 are arranged, so that the volume of the drainage liquid can be conveniently controlled, and the patient can be treated in time;

when no longer reducing pressure to patient's stomach intestine, at first promote ejector pad 14 backward, make ejector pad 14 no longer block on stopper 13, this moment under the effect of extension spring 15, extension spring 15 drives slider 7 along 6 clockwise rotations of arc wall, slider 7 swings along dead lever 3 mutually back mutually through 8 pulling clamp plate 4 of connecting rod, make clamp plate 4 no longer press from both sides tightly the stomach tube, elastic ring 17 no longer blocks in draw-in groove 16, extract the stomach tube from stand pipe 2 thereupon, then collect the drainage liquid in the barrel 1, the operation is accomplished.

Compared with the prior art, the beneficial effects of the utility model are that: through the clamp plate that sets up, elastic ring and draw-in groove, not only be convenient for fix the stomach tube better on the stand pipe, also can increase the gas tightness of stand pipe and stomach tube junction, avoid drainage liquid to spill over through the stand pipe with the junction of stomach tube, the effectual effect of having improved the decompression of patient's stomach intestine, the venthole that is equipped with, exhaust needle and the ventilated membrane that blocks water, not only can effectively carry out the ordinary pressure decompression to patient's stomach intestine, also the effectual drainage liquid that avoids overflows through the venthole, the damage to patient's stomach wall has been reduced simultaneously, better treatment is carried out to the patient, this simple structure, high durability and convenient operation, the design is novel, therefore, the clothes hanger.
