Description

Technical Field

[0001] The utility model belongs to the technical field of medical gastric tubes, and in particular relates to a fixing structure of a medical gastric tube. Background Art

[0002] As the most common device in the medical field, gastric tubes are used to deliver necessary water and food to patients who cannot swallow in special circumstances. In order to reduce the discomfort of patients during use, the fixation of gastric tubes is often crucial.

[0003] The existing patent with announcement number CN206730250U provides a gastric tube fixer, including an inner tube clamp, an outer tube clamp and a rope. The inner tube clamp and the outer tube clamp are both made of elastic material. The inner tube clamp includes a tube clamp body, and axial incisions are opened at both ends of the tube clamp body; the outer tube clamp includes a jacket body, and the inner surface of the jacket body matches the outer surface of the tube clamp body; and axial openings are opened at both ends of the jacket body.

[0004] The fixator first inserts the gastric tube into the tube clamp body from the axial incision, and then inserts the tube clamp body into the jacket body from the axial opening, and fixes the gastric tube through the double-layer clamping of the tube clamp body and the jacket body. The tube clamp body and the jacket body are generally made of plastic. Since different gastric tubes have different shapes and sizes, when clamping gastric tubes of different sizes, the clamp needs to rely on the elasticity of its own material to make adaptive adjustments to clamp and fix the gastric tube. However, during long-term adjustment and use, the material of the clamp itself becomes fatigued, resulting in weakened elasticity, thereby affecting the clamping effect of the fixator on the gastric tube.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0024] Embodiment 1

[0025] like Figure 1-Figure 4 As shown, the technical solution adopted by the utility model is as follows: a fixing structure of a medical gastric tube, comprising a fixing box 2, a gastric tube 1 is penetrated in the fixing box 2, a first slide groove 5 is opened in the fixing box 2; a clamping assembly is arranged in the first slide groove 5.

[0026] Two fixing seats 4 are fixedly and symmetrically arranged on both sides of the fixing box 2, a rotating shaft 7 is rotatably arranged between the two fixing seats 4, and a tightening belt 3 is wrapped around the outer circumference of the rotating shaft 7. The tightening belt 3 has a certain elasticity and is specifically made of a silicone material.

[0027] The clamping assembly includes a clamping plate 10, two clamping plates 10 are slidably arranged in the first chute 5, a gastric tube 1 is installed between the two clamping plates 10, and the two clamping plates 10 are both arranged in a semicircular arc shape, and the facing surfaces of the two clamping plates 10 are concave surfaces, which facilitate the clamping plates 10 to clamp the gastric tube 1. Second chute 9 is provided on both sides of the first chute 5, and a slide plate 6 is slidably arranged in each of the second chute 9, and the slide plate 6 is fixedly connected to the adjacent clamping plates 10; three springs 8 are fixedly arranged at one end of the slide plate 6 away from the clamping plate 10, and the other end of each spring 8 is fixedly connected to the fixed box 2. The rotating shaft 7 is transmission-connected to the input end of the clamping assembly.

[0028] Two cross slides 13 are provided on both sides of the fixing box 2 and the tightening belt 3, and a cross slide 11 is slidably arranged in each cross slide 13. A rack 12 is fixedly arranged at the bottom of the cross slide 11, and one end of the cross slide 11 away from the rotating shaft 7 is fixedly connected to the slide 6. A gear 14 is fixedly sleeved on the rotating shaft 7, and the gear 14 meshes with the rack 12.

[0029] By pulling the tightening belt 3, the tightening belt 3 will drive the rotating shaft 7 to rotate, and the rotating shaft 7 will rotate and drive the gear 14 to rotate, and the gear 14 will drive the rack 12 to slide in the direction close to the gastric tube 1, and the rack 12 will slide in the direction close to the gastric tube 1 and push the slide plate 6 and the clamp plate 10 to slide in the direction close to the gastric tube 1, thereby fixing the gastric tube 1. At this time, the spring 8 is in a stretched state, and when the external force ends, the spring 8 will pull the slide plate 6 to slide in the direction away from the gastric tube 1 due to its own elasticity, and the slide plate 6 slides in the direction away from the gastric tube 1, thereby driving the rack 12 to slide in the direction away from the gastric tube 1, and the rack 12 slides in the direction away from the gastric tube 1, thereby driving the gear 14 to rotate in the opposite direction, and the gear 14 rotates in the opposite direction, thereby driving the rotating shaft 7 to rotate in the opposite direction, thereby driving the tightening belt 3 to reset and wrap around the rotating shaft 7.

[0030] How it works

[0031] When in use, the medical staff first passes the gastric tube 1 through the fixing box 2, and then pulls the tightening belt 3 outward. Since the tightening belt 3 itself has a certain elasticity, it can be tightened to certain parts of the patient's body by setting Velcro at the ends of the two tightening belts 3 away from the fixing seat 4. In the process of pulling the tightening belt 3, the rotating shaft 7 will rotate, and the rotation of the rotating shaft 7 will drive the gear 14 to rotate. The rotation of the gear 14 will drive the rack 12 to slide in the direction close to the gastric tube 1. The rack 12 slides in the direction close to the gastric tube 1 and pushes the slide plate 6 and the clamp plate 10 to slide in the direction close to the gastric tube 1, thereby fixing the gastric tube 1. After the gastric tube 1 is fixed, the gastric tube 1 is placed in the patient's body.

[0032] When the stomach tube 1 is fixed, the spring 8 is in a stretched state. When the external force ends, the spring 8 will pull the slide plate 6 to slide away from the stomach tube 1 due to its own elasticity, and the slide plate 6 slides away from the stomach tube 1, thereby driving the rack 12 to slide away from the stomach tube 1, and the rack 12 slides away from the stomach tube 1, thereby driving the gear 14 to rotate in the opposite direction, and the gear 14 rotates in the opposite direction, thereby driving the rotating shaft 7 to rotate in the opposite direction, thereby driving the tightening belt 3 to return to its original position and be wound around the rotating shaft 7.

[0033] Embodiment 2

[0034] like Figure 5As shown, compared with the first embodiment, the second embodiment is that two ropes 15 are wound around the outer circumference of each rotating shaft 7. One end of the rope 15 is fixed to the rotating shaft 7. The end of the rope 15 away from the rotating shaft 7 movably passes through one side of the fixed box 2 and is fixedly connected to the slide plate 6; the rotating shaft 7 is provided with a torsion spring, one end of the torsion spring is fixedly connected to the rotating shaft 7, and the other end of the torsion spring is fixedly connected to the fixed seat 4. Moreover, in the absence of external force and extrusion, the torsion force of the torsion spring on the same side is greater than the sum of the elastic forces of the three springs 8 on the same side, so in the initial state, the spring 8 is in a compressed state.

[0035] By pulling the tightening belt 3, the tightening belt 3 will drive the rotating shaft 7 to rotate, and the rotation of the rotating shaft 7 will cause the rope 15 to rotate, thereby controlling the rope 15 to release the line. Since the spring 8 is in a compressed state in the initial state, when an external force is applied to the tightening belt 3, the torsion force of the torsion spring decreases. The slide plate 6 will move toward the direction close to the gastric tube 1 under the combined action of the external force and the spring 8. The slide plate 6 moves toward the direction close to the gastric tube 1, thereby driving the splint 10 to move toward the direction close to the gastric tube 1, and then the gastric tube 1 is fixed by the splint 10. When the external force ends, the torsion spring will drive the rotating shaft 7 to rotate in the opposite direction, thereby driving the slide plate 6 to slide in the direction away from the gastric tube 1, thereby squeezing the spring 8, so that the tightening belt 3 is reset.

[0036] How it works

[0037] Compared with the first embodiment, in the second embodiment, when the tightening belt 3 is pulled outward, the tightening belt 3 will drive the rotating shaft 7 to rotate, and the rotation of the rotating shaft 7 will cause the rope 15 to rotate, thereby controlling the rope 15 to release the line. Since the elasticity of the torsion spring is greater than the elasticity of the spring 8 in the initial state, the spring 8 is in a compressed state. When an external force is applied to the tightening belt 3, the torsion force of the torsion spring decreases. The slide plate 6 will move toward the direction close to the gastric tube 1 under the combined action of the external force and the spring 8, and the slide plate 6 moves toward the direction close to the gastric tube 1, thereby driving the splint 10 to move toward the direction close to the gastric tube 1, and then the gastric tube 1 is fixed by the splint 10.

[0038] When the external force ends, the torsion spring drives the rotating shaft 7 to rotate in the opposite direction, thereby driving the slide plate 6 to slide away from the stomach tube 1, thereby squeezing the spring 8 and resetting the tightening band 3.
