Examples

As shown in fig. 1-4, the multifunctional gastric tube convenient for filling nutrient solution in this embodiment includes a connecting tube 10, a first conduit 11 and a second conduit 12 respectively disposed at two ends of the connecting tube 10, a solution filling tube 20 conductively connected to a sidewall of the connecting tube 10, a blocking piece 21 disposed at an end of the solution filling tube 20 close to one end of the connecting tube 10, and a first pushing block 22, a first elastic cord 26 and a second elastic cord 27 disposed inside the solution filling tube 20; one end of the first elastic rope 26 is fixedly connected with one end of the liquid feeding pipe 20 far away from the connecting pipe 10, and the other end is fixedly connected with the first push block 22; one end of the second elastic rope 27 is fixedly connected with the first push block 22, and the other end is fixedly connected with the baffle 21; the baffle 21 is hinged with one side of the end of the filling pipe 20 close to the first conduit 11, and the baffle 21 is used for shielding the first conduit 11. Specifically, the tube may be used as a conventional gastrointestinal decompression tube in use, in which the first catheter tube 11 is used for connection with an instrument, the second catheter tube 12 is used for insertion into the inside of the human body, and the connection tube 10 serves to connect the first catheter tube 11 and the second catheter tube 12. When nutrient solution or medicine needs to be injected into a patient, the injector 30 (without a needle head) can be directly used for sucking liquid, then the injector 30 is inserted into the liquid adding pipe 20, at the moment, the nipple part of the injector 30 can prop against the first push block 22 and push the first push block 22 to move, the first push block 22 can push the baffle 21, the baffle 21 rotates and props against the inner wall of the connecting pipe 10, and then the first pipe 11 and the connecting pipe 10 are blocked, so that the first pipe 11 and the connecting pipe 10 are blocked, at the moment, the injector 30 is pushed, and the liquid in the injector 30 enters a human body after passing through the liquid adding pipe 20, the connecting pipe 10 and the second pipe 12. After the injection is completed, the injector 30 is pulled out, at this time, the first push block 22 returns to the previous position under the elastic force of the first elastic rope 26, and the baffle 21 also returns to the previous position (blocking the liquid feeding pipe 20) under the elastic force of the second elastic rope 27, so that the nutrient solution can be conveniently filled into the patient, the first conduit 11 can be automatically sealed, the liquid is prevented from flowing into an instrument or the outside through the first conduit 11, the use is more convenient, and no other additional instrument is needed. It should be noted that, in order to ensure the normal operation of the first pushing block 22 and the blocking piece 21, the connecting tube 10 and the filling tube 20 need to be made of hard materials, such as hard plastics.

The first push block 22 in this embodiment has a first through hole 23 formed along a direction parallel to the axis of the filler tube 20. Specifically, after the liquid is pushed out from the syringe 30, the liquid can rapidly flow into the connection tube 10 from the first through hole 23.

The first push block 22 in this embodiment is slidably connected to the side wall of the filler tube 20. In particular, the movement of the first push block 22 is thus more stable.

In the embodiment, a second push block 24 is fixedly arranged at one end part of the first push block 22 close to the connecting pipe 10; the second push block 24 is connected with an inner side wall of the liquid feeding pipe 20 close to the second guide pipe 12 in a sliding manner, and a gap is formed between the second push block 24 and the inner side wall of the liquid feeding pipe 20 close to the first guide pipe 11; the second pushing block 24 is provided with a second through hole 25 along the axial direction of the filling pipe 20, and the second through hole 25 is communicated with the first through hole 23. Specifically, the second pushing block 24 is mainly used for pushing the blocking sheet 21 to rotate.

The cross section of the inside of the liquid adding pipe 20 in the embodiment along the direction vertical to the axis is square; the flap 21 has a width equal to the width of the interior of the filler tube 20 and the flap 21 has a length greater than the width of the interior of the filler tube 20. In particular, the baffle 21 is inclined against the inner wall of the connecting tube 10, so as to better separate the first conduit 11 from the connecting tube 10.

The filler tube 20 in this embodiment has an end portion remote from the connecting tube 10 smaller in inner diameter than the other end portion. In particular, such that when syringe 30 is inserted into filler tube 20, there is a gap between the nipple portion of syringe 30 and the interior of filler tube 20 that is capable of receiving first elastic cord 26.

In this embodiment, a dust cap 28 is included to close the filler tube 20. In particular, although the flap 21 may also separate the connecting tube 10 from the filler tube 20, the provision of a dust cap 28 on the filler tube 20 may better separate the filler tube 20 and the connecting tube 10 from the outside.

The side edge of the baffle 21 in this embodiment is provided with a rubber layer. In particular, this makes it possible to better reduce the clearance between the flap 21 and the inner wall of the connection tube 10.

The connecting pipe 10 in the embodiment is detachably connected with the first conduit 11 and the second conduit 12; the first conduit 11 is detachably connected to the second conduit 12. Specifically, since the structure of the inner part of the connecting tube 10 and the filling tube 20 is more complicated and more costly, when a patient is intubated, it can be determined in advance whether the patient will need to be filled with nutrient solution or medicine during the intubation, and if not, the first conduit 11 and the second conduit 12 can be directly connected for use, so that the cost can be reduced.

In summary, the multifunctional gastric tube convenient for feeding nutrient solution of the present embodiment can use the tube as a conventional gastrointestinal decompression tube when in use, wherein the first conduit 11 is used for connecting with the instrument, the second conduit 12 is used for inserting into the human body, and the connecting tube 10 plays a role of connecting the first conduit 11 and the second conduit 12. When nutrient solution or medicine needs to be injected into a patient, the injector 30 (without a needle head) can be directly used for sucking liquid, then the injector 30 is inserted into the liquid adding pipe 20, at the moment, the nipple part of the injector 30 can prop against the first push block 22 and push the first push block 22 to move, the first push block 22 can push the baffle 21 again, so that the baffle 21 rotates and props against the inner wall of the connecting pipe 10, and then is blocked between the first conduit 11 and the connecting pipe 10, the effect of blocking the first conduit 11 and the connecting pipe 10 is realized, at the moment, the injector 30 is pushed, and the liquid in the injector 30 enters a human body after passing through the liquid adding pipe 20, the connecting pipe 10 and the second conduit 12. After the injection is completed, the injector 30 is pulled out, at this time, the first push block 22 returns to the previous position under the elastic force of the first elastic rope 26, and the baffle 21 also returns to the previous position (blocking the liquid feeding pipe 20) under the elastic force of the second elastic rope 27, so that not only can the nutrient solution be conveniently filled into the patient, but also the first conduit 11 can be automatically sealed, the liquid is prevented from flowing into the instrument or the outside through the first conduit 11, the use is more convenient, and no other additional instrument is needed.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
