Technical Field
[0001] This utility model relates to the field of medical device technology, specifically to a gastric tube insertion auxiliary device. Background Technology
[0002] When inserting a gastric tube, the outer surface of the gastric tube needs to be coated with a lubricating medium to reduce damage to the mucosa of the human digestive tract during the insertion process.
[0003] Existing intubation assistance devices mostly guide the gastric tube by using a ring or tubular structure wrapped around it. However, the device itself needs to be wrapped starting from the end of the gastric tube. The number of devices cannot be increased during the intubation process, and it is difficult to remove, which brings inconvenience to the gastric tube intubation operation.
[0004] At the same time, due to the slippery nature of the gastric tube, it is difficult to control the amount of gastric tube inserted when manually grasping it, and the placement and adjustment of the gastric tube in the affected area are very inconvenient. Utility Model Content

[0008] A guide shell is fixedly connected to the surface of the semi-straight tube. The guide shell is arranged along the generatrix of the outer surface of the semi-straight tube. A draw strip is longitudinally inserted at the bottom of the guide shell. An extrusion block is slidably connected to the side surface of the draw strip.

[0010] Optionally, the axis of the semi-straight tube is collinear with the axis of the semi-conical tube, and the top end face of the semi-straight tube and the bottom end face of the semi-conical tube are fixedly connected to form a single unit mechanism. The two single units mechanism are symmetrically arranged about the axis of the semi-straight tube, and the two single units mechanism are spliced together to form a trumpet-shaped structure.
[0011] Optionally, the two pressing flaps are fixedly connected to the semi-straight tubes of the two individual mechanisms, and the two pressing flaps are respectively arranged on the generatrix of the mutual contact position of the two semi-straight tubes.
[0012] Optionally, the guide shell has a U-shaped groove structure, the top of the guide shell is sealed, and the pull strip passes through the bottom of the guide shell and is slidably connected to the inner surface of the guide shell.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0024] This utility model provides, for example Figure 1-3 The illustrated gastric tube insertion aid includes a semi-straight tube 1 and a semi-conical tube 2, which are fused together as a single unit. The centerline of the semi-straight tube 1 is collinear with that of the semi-conical tube 2, and the top end face of the semi-straight tube 1 is fixedly connected to the bottom end face of the semi-conical tube 2 to form a single unit. The two single units are symmetrically arranged about the centerline of the semi-straight tube 1 and are spliced together to form a trumpet-shaped structure. The semi-conical tube 2 guides the insertion of the gastric tube. By incorporating the semi-straight tube 1, the semi-conical tube 2, the pressure valve 3, and the torsion spring 5, the device forms a trumpet-shaped clamp structure, which facilitates the clamping of the gastric tube, guides the insertion process, and allows for quick removal from the gastric tube, making it more convenient to use.
[0025] A pressing flap 3 is fixedly installed on the side surface of the semi-straight tube 1. The pressing flap 3 has an L-shaped bending structure. The two pressing flaps 3 correspond one-to-one with the two semi-straight tubes 1. The two pressing flaps 3 are fixedly connected to the semi-straight tubes 1 of the two single-unit mechanisms. The two pressing flaps 3 are respectively set on the generatrix at the mutual contact position of the two semi-straight tubes 1. By squeezing the outer ends of the two pressing flaps 3, the two pressing flaps 3 rotate relative to each other around the deflection shaft 4. This causes the pressing flaps 3 to drive the generatrix at the mutual contact position of the two semi-straight tubes 1 to create an opening gap, realizing a clamp-like opening action. This makes it easy to place the device on the outer surface of the gastric tube through the gap between the two semi-straight tubes 1, and also makes it easy to remove the device from the surface of the gastric tube, realizing quick installation and disassembly. The deflection shaft 4 is longitudinally sleeved at the inflection point of the two pressing flaps 3. The surface of the deflection shaft 4 is sleeved with a torsion spring 5. The two ends of the torsion spring 5 are fixedly connected to the surface of the two semi-straight tubes 1 respectively.
[0026] A guide shell 6 is fixedly connected to the surface of the semi-straight tube 1. The guide shell 6 has a U-shaped groove structure and a sealed top. A pull strip 7 passes through the bottom of the guide shell 6 and slides with the inner surface of the guide shell 6. The guide shell 6 is set along the generatrix of the outer surface of the semi-straight tube 1. The pull strip 7 is longitudinally inserted into the bottom of the guide shell 6. Both the pull strip 7 and the extrusion block 8 are wedge-shaped blocks, and the contact surface of the pull strip 7 and the extrusion block 8 that slides with each other is an inclined surface that is inclined to the generatrix of the semi-straight tube 1. The pull strip 7 is made of rubber, and the outer surface of the pull strip 7 and the inner surface of the guide shell 6 are connected. The surface is pressed together, and under non-human force, the deformation of the surface of the pull strip 7 results in a large static friction between the pull strip 7 and the guide shell 6. The relative position between the pull strip 7 and the guide shell 6 is fixed, that is, the relative position between the pressing block 8 and the semi-straight tube 1 is fixed. The pressing block 8 is slidably connected to the side surface of the pull strip 7. The pressing block 8 penetrates the outer surface of the semi-straight tube 1 and extends to the inner side of the semi-straight tube 1. The pressing block 8 and the semi-straight tube 1 are interlocked. The side surface of the pressing block 8 near the axis of the semi-straight tube 1 is concave, and the edge where the concave surface meets the vertical surface of the pressing block 8 is rounded. The pressing block 8 can clamp and fix the gastric tube sleeved inside the semi-straight tube 1, realizing the locking of the relative position between the device and the gastric tube. The position of the gastric tube can be adjusted by directly adjusting the position of the device, and the gastric tube insertion action can be controlled to stop. By setting up a guide shell 6, a pull strip 7, and a squeezing block 8, the operator can push the pull strip 7 into the inside of the guide shell 6 to cause the squeezing block 8 to clamp the gastric tube sleeved inside the semi-straight tube 1, and fix the relative position between the device and the gastric tube. By adjusting the device, the position of the gastric tube can be quickly grasped and adjusted, and the current intubation rate can be maintained, making it more user-friendly.
[0027] The bottom of the semi-straight tube 1 is fixedly fitted with an end ring 9, which has a C-shaped structure, and the bottom of the end ring 9 is fixedly connected with an integrated semi-soft cone 10.
[0028] The working principle of this utility model is as follows: By squeezing the two compression valves 3, the outer ends of the two compression valves 3 move towards each other, causing the two compression valves 3 to rotate relative to the deflection axis 4, which in turn causes the two semi-straight tubes 1 and the semi-conical tube 2 to open apart, achieving an opening effect similar to a clamp. Then, the semi-straight tube 1 of the device is clamped onto the surface of the gastric tube to achieve the assembly action. At the same time, by squeezing the compression valves 3, the two semi-straight tubes 1 can be opened, and the gastric tube can be pulled out from the gap between the two semi-straight tubes 1 to achieve the separation action between the device and the gastric tube.
[0029] When the semi-straight tube 1 of the device is fitted on the outside of the gastric tube, the gastric tube can be pulled at the semi-conical tube 2 position by grasping the semi-straight tube 1 to realize the removal and insertion of the gastric tube. Through the opening structure of the semi-conical tube 2, the action of pushing the gastric tube to the semi-straight tube 1 and the patient's affected area is better guided, and the insertion action is smoother.
[0030] Press the pull strip 7 into the guide shell 6. The inclined surface of the pull strip 7 slides relative to the inclined surface of the compression block 8. The pull strip 7 pushes the compression block 8 closer to the axis of the semi-straight tube 1. That is, the compression block 8 compresses and restricts the outer surface of the gastric tube fitted inside the semi-straight tube 1, thereby fixing the relative position of the semi-straight tube 1 and the gastric tube currently fitted and in contact with it. The position of the gastric tube and the feed rate can be adjusted by directly operating and dragging the device. This avoids the inconvenience of operation caused by the slippery surface of the gastric tube, making it more convenient and simple to use. The insertion operation is also more precise, reducing the impact on the patient's body.
[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
