[0002] A gastric tube refers to a tube that delivers medicine, liquid food, etc. to the stomach. Usually, one end of the tube is inserted from the nostril and directly into the stomach. The outer end of the hose is adhered to the face with tape. The end of the hose is usually connected to a docking part, and personnel use a syringe to inject the liquid into the hose.

[0003] When performing a gastric tube injection, the personnel will first observe the position of the gastric tube and whether the gastric tube is entangled inside the mouth to determine whether the gastric tube is in the stomach. Then they will open the docking part, inject warm water to moisten the hose, and then slowly inject the liquid food multiple times. When injecting, usually one hand holds the hose and the other hand picks up the syringe to aspirate the liquid, and then align it for injection. When there is no injection, the personnel needs to bend the hose to prevent liquid food from overflowing or gas from entering. The entire injection process is cumbersome for one person to operate with both hands, and it is easy to cause gas to enter the gastric tube or liquid food to overflow due to mistakes.

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Example 1: Please refer to Figure 1 - Figure 4 The stomach tube fixing device shown in the figure includes a hose 1 and an injection tube 2. A docking portion 3 is provided between the injection tube 2 and the hose 1, and the two clamps 4 are fixedly connected by the docking portion 3; and two clamps 4. A connecting portion 5 is installed between the two clamps 4. The connecting portion 5 makes one end of the two clamps 4 close to each other. The inner sides of the two clamps 4 are provided with a tightening portion 6. The tightening portion 6 presses the injection tube 2 tightly to prevent the backflow of food in the injection tube 2 and the entry of gas; and a fixing portion 7 installed between the two clamps 4. The fixing portion 7 realizes the fixation of the injection tube 2;

[0028] In this solution, the hose 1 and the injection tube 2 are docked through the docking part 3 to achieve integrated docking, and then the hose 1 is inserted into the stomach from the nostrils to realize the normal liquid food supply function of the gastric tube. Afterwards, the two splints 4 and the connecting part 5 cooperate with each other to drive the pressing part 6 to compress the injection tube 2. The person controls the compressed state of the injection tube 2 by controlling the two splints 4, thereby realizing the operation of holding the tube with one hand and injecting liquid food with one hand, making the operation of injecting liquid food easier and more convenient.

[0029] For further information, see Figure 5 - Figure 7The connecting portion 5 includes a connecting column 8, two connecting plates 9 are rotatably mounted at both ends of the connecting column 8, the two connecting plates 9 are respectively fixed to the inner sides of the two clamping plates 4, and the outer side of the connecting column 8 is covered with a torsion spring 10 fixed to the two clamping plates 4. The torsion spring 10 enables the two connecting plates 9 to drive the two clamping plates 4 to rotate;

[0030] The pressing portion 6 includes a pressing protrusion 18 fixed on the inner side of the clamping plate 4 , and the pressing protrusion 18 fits against the outer side of the injection tube 2 .

[0031] It should be noted that when injecting liquid food, the personnel pinch the two clamps 4 with one hand, so that the two clamping protrusions 18 in the clamping part 6 move outward, and are separated from the injection tube 2, so that the injection tube 2 is in a flowing state. At this time, the personnel aligns the syringe with the injection tube 2 to inject the liquid food. After the injection is completed, the personnel loosens the clamps 4, and under the action of the torsion spring 10, the two clamping protrusions 18 can be clamped against the injection tube 2 again, realizing the compression operation of the injection tube 2, thereby having the effect of bending the pipe to prevent the backflow of the liquid food. At this time, the personnel can use the syringe to inhale the liquid food again, and then continue to inject the liquid food by pinching the clamps 4.

[0032] It should also be noted that in order to improve the tightening effect on the injection tube 2, anti-slip grooves are provided on the outer side of the tightening protrusion 18, and a tightening ring groove 19 is provided at the injection tube 2 corresponding to the tightening protrusion 18. The design of the tightening ring groove 19 makes the tube wall thickness of the injection tube 2 corresponding to the tightening protrusion 18 area thinner, which is convenient for squeezing and flattening.

[0033] For further information, see Figure 1 as well as Figure 3 The docking portion 3 includes a docking female connector 11 fixed to one end of the hose 1 and a docking male connector 12 fixed to one end of the injection tube 2. The docking female connector 11 and the docking male connector 12 are plugged into each other. A sealing ring 13 is fixed on the docking female connector 11, and a sealing groove 14 adapted to the sealing ring 13 is provided in the docking male connector 12.

[0034] In order to improve the stability of the operation between the docking female head 11 and the docking male head 12, anti-slip grooves are provided on the outer sides of the docking female head 11 and the docking male head 12;

[0035] It should be noted that the use of the docking portion 3 to dock the hose 1 and the injection tube 2 can make it easier to disassemble the injection tube 2 from the hose 1. When the patient wears a gastric tube for a long time to supply liquid food, the syringe 2 can be disassembled to make it more convenient to clean it without removing the hose 1, thereby avoiding the foreign body sensation caused by removing the hose 1.

[0036] For further information, see Figure 2 - Figure 5The fixing part 7 includes a connecting rod 15 fixed to the outer end of the connecting column 8, and a fixing ring 16 is fixed on the connecting rod 15 and is sleeved with the injection tube 2; wherein, in order to improve the stability of injection after the person aligns the syringe with the injection tube 2, a thickened tube 17 is fixed to the outside of the injection tube 2, and the fixing ring 16 is sleeved on the outside of the thickened tube 17.

[0037] In this plan, the specific process of delivering liquid food through a gastric tube includes the following steps:

[0038] In the first step, the personnel first insert the hose 1 through the nostrils to the stomach, and then use tape to stick it to the face;

[0039] The second step is to connect the hose 1 with the injection tube 2 using the docking portion 3;

[0040] In the third step, the person first pinches the two splints 4 with one hand to open the abutting portion 6, and then uses the syringe to suck the injection substance, injects the injection substance into the injection tube 2, and flows into the stomach through the hose 1;

[0041] In the fourth step, after the injection is completed, the person releases the clamp 4. Under the action of the torsion spring 10, the pressing part 6 compresses the injection tube 2 again to prevent backflow and gas ingress. At the same time, the person uses the syringe to inhale the substance to be injected.

[0042] Step 5. Repeat steps 3 and 4 several times until the injection is completed.

[0043] Example 2: Please refer to Figure 1 - Figure 7 This embodiment further explains the first embodiment, and the difference lies in that the fixing portion 7 is optimized and a partial structure of the fixing portion 7 is added.

[0044] Specifically, a connecting belt 20 is fixed to the outside of the fixing ring 16, and a plug 21 adapted to the outer end of the thickened tube 17 is fixed to the outer end of the connecting belt 20. The design of the plug 21 can effectively block the thickened tube 17, and can effectively block the thickened tube 17 when no liquid food is injected. When combined with the collapsed injection tube 2, it can further prevent gas from entering.

[0045] At the same time, the fixing portion 7 further includes an annular plate 22 fixed to the outer end of the clamping plate 4 , and the two annular plates 22 are buckled together to form a circular ring shape.

[0046] In this solution, the additional annular plate 22 can cooperate with the rotation of the splint 4 to achieve a circular engagement, which is engaged with the cylinder around the bed to fix the injection tube 2.
