Abstract
Description
Technical Field
[0001] This utility model relates to the field of gastroscopy tube fixation technology, and in particular to a gastroscopy tube fixation device. Background Technology
[0002] Gastroscopy is a core tool in the diagnosis of upper gastrointestinal diseases (such as gastritis, gastric ulcers, and gastric cancer) in gastroenterology. The standardized operation of the entire process directly affects the accuracy of diagnosis and patient safety. In the entire process of gastroscopy, the stable fixation of the endoscope tube is a key link to ensure the smooth operation. The patient's occlusion fixation is a core step, and its safety and standardization are directly related to the quality of medical care and the health of the patient.
[0003] Traditional gastroscopy tube fixation methods use silicone bite sleeves as a buffer during patient biting. The flexibility of silicone effectively prevents direct contact between the patient's teeth and the rigid fixator, significantly reducing oral discomfort and the risk of tooth damage during the examination. This is suitable for clinical scenarios involving prolonged examinations and, to some extent, improves the patient's experience and cooperation. However, due to the lack of effective means to visually assess the condition of the bite sleeve, there is a risk of reuse after disinfection. Although disinfection can reduce the microbial load to some extent, reusing the bite sleeve cannot fundamentally eliminate the possibility of cross-infection. This clearly conflicts with the increasingly stringent infection control standards in the healthcare industry, posing a potential threat to medical safety. Utility Model Content
[0004] This utility model relates to a gastroscopy tube fixation device, which solves the problem that there is currently no effective means to intuitively judge the usage status of the occlusal sleeve, and that the occlusal sleeve may be reused after disinfection.
[0005] This utility model provides a gastroscopy tube fixation device, specifically including: an oral fixator, the oral fixator having an elliptical block structure, and a gastroscopy tube insertion hole penetrating its front and rear faces at the axial center of the oral fixator; an occlusal groove is formed on the outer peripheral surface of the oral fixator, and a set of silicone occlusal sleeves are fitted inside the occlusal groove, the structural dimensions of the silicone occlusal sleeves matching the structural dimensions of the occlusal groove; a permanent marking embedded layer is embedded in the top and bottom of the outer peripheral surface of the silicone occlusal sleeves, the permanent marking embedded layer being a temperature-sensitive color-changing silicone.
[0006] Furthermore, a retainer pad is fixedly installed on the outer peripheral surface of the mouth retainer adjacent to the front side edge, and a nose-fitting notch is provided on the top of the retainer pad.
[0007] Furthermore, the mouth fixator has three storage slots arranged in a circular array on both the front and rear sides. The storage slots are circular and connect to the endoscope tube insertion hole. The front and rear faces of the mouth fixator have shaft holes that communicate with the storage slots relative to the axis of the storage slots.
[0008] Furthermore, a rotating shaft is rotatably installed inside the shaft hole, and a knob block is fixedly installed at the axial center of the front end face of the rotating shaft; a rubber clamping sleeve is sleeved on the front side of the outer periphery of the rotating shaft, and the rubber clamping sleeve is located between the rear end face of the knob block and the front end face of the mouthpiece retainer, and they are in close contact.
[0009] Furthermore, a cam fixing component is fixedly installed on the outer circumferential surface of each of the aforementioned shafts. The cam fixing component is located inside the receiving groove, and a rubber limiting sleeve is fixedly installed on the outer circumferential surface of the cam fixing component.
[0010] This utility model provides a gastroscopy tube fixation device, which has the following beneficial effects:
[0011] This invention uses a rotary knob block to drive the rotating shaft and cam fixing components to rotate. The eccentric contour of the cam compresses the outer circumference of the tube, and the rubber limiting sleeve on the outer circumference of the cam fixing component provides flexible clamping force, avoiding tube deformation or damage caused by traditional rigid clamping. Furthermore, based on the pressure applied by the six cam fixing components from different directions, a 360-degree circumferential uniform fixing effect is formed, effectively preventing the endoscope tube from sliding or shaking during the examination due to the patient's swallowing, peristalsis and other actions, thus improving the stability of operation.
[0012] This invention relates to a mouth fixation device with a silicone bite sleeve fitted inside the bite groove. The elastic deformation properties of silicone material absorb the patient's biting pressure, avoiding pain or wear caused by direct contact between the teeth and the rigid fixation device. It is especially suitable for long-term examination scenarios, reducing oral fatigue.
[0013] The outer periphery of this utility model features a permanent, thermosensitive, color-changing silicone embedded layer at the top and bottom. When the patient bites, the contact area experiences a local temperature increase due to friction or body heat conduction, causing an irreversible color change in the permanent, color-changing embedded layer. This feature allows for a direct assessment of whether the bite sleeve has been used after the examination, effectively eliminating the possibility of reuse after disinfection. This design completely cuts off the route of cross-infection and meets the infection control standards of the medical and health industry. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0027] Example: Please refer to Figures 1 to 7 :
[0028] This utility model proposes a gastroscopy tube fixation device, including: an oral fixator 1, which is an elliptical block structure, with a gastroscopy tube insertion hole 101 through its front and rear ends at the axial center of the oral fixator 1; an occlusal groove 103 is formed on the outer peripheral surface of the oral fixator 1, and a set of silicone occlusal sleeves 3 are fitted inside the occlusal groove 103, the structural dimensions of the silicone occlusal sleeves 3 matching the structural dimensions of the occlusal groove 103; a permanent marking embedded layer 301 is embedded in the top and bottom of the outer peripheral surface of the silicone occlusal sleeves 3, the permanent marking embedded layer 301 being a temperature-sensitive color-changing silicone; a retaining pad 2 is fixedly installed on the outer peripheral surface of the oral fixator 1 adjacent to the front side edge, the top of the retaining pad 2 having a nasal matching notch 201, which facilitates that when the retaining pad 2 is in contact with the face, the nasal matching notch 201 corresponds to the patient's nasal area, so that the retaining pad 2 does not contact the patient's nose.
[0029] In this embodiment, the mouth fixator 1 has three storage slots 102 arranged in a circular array on its front and rear sides. The storage slots 102 are circular and connect to the endoscope tube insertion hole 101. The front and rear faces of the mouth fixator 1 have shaft holes 104 that communicate with the storage slots 102. A rotating shaft 402 is rotatably installed inside the shaft hole 104. A knob block 4 is fixedly installed at the center of the front face of the rotating shaft 402. A rubber abutment sleeve 404 is sleeved on the front side of the outer periphery of the rotating shaft 402. The rubber abutment sleeve 404 is located between the rear face of the knob block 4 and the front face of the mouth fixator 1, and they are in close contact. A cam fixing member 403 is fixedly installed on the outer periphery of each rotating shaft 402. The cam fixing member 403 is located inside the storage slot 102, and a rubber limiting sleeve 401 is fixedly installed on the outer periphery of the cam fixing member 403.
[0030] The working principle of this embodiment:
[0031] The endoscope tube is passed through the endoscope tube insertion hole 101, and the patient is guided to bite down and hold the fixator 1 so that the pad 2 fits against the face. The notch 201 on the nose corresponds to the patient's nasal area, so that the pad 2 does not touch the patient's nose and ensures that the pad 2 does not cause discomfort to the patient's nose.
[0032] When the patient bites down and holds the fixator 1 in their mouth, their teeth will contact the silicone bite sleeve 3 fitted inside the occlusal groove 103. The elastic deformation of the silicone bite sleeve absorbs the biting pressure, reducing the discomfort caused by direct contact between the patient's teeth and the fixator 1. Furthermore, a permanent traceable inner layer 301 made of temperature-sensitive color-changing silicone is embedded in the top and bottom of the outer peripheral surface of the silicone bite sleeve 3. With the permanent traceable inner layer 301, when the patient bites down, the local temperature at the contact area with the permanent traceable inner layer 301 increases, and the color of the permanent traceable inner layer 301, which is a temperature-sensitive material, changes. This color change has the characteristic of "permanent traceability". After the gastroscopy, the silicone bite sleeve 3 can be forcibly replaced by this characteristic of "permanent traceability", avoiding the reuse of the silicone bite sleeve 3 after disinfection and minimizing the possibility of cross-infection.
[0033] When fixing the endoscope tube, rotating the knob block 4 causes the rotating shaft 402 to rotate the cam fixing member 403. The eccentric contour of the cam fixing member 403 presses against the outer circumferential surface of the endoscope tube, while the rubber limiting sleeve 401 on the outer circumferential surface of the cam fixing member 403 provides flexible clamping force through elastic contact, avoiding rigid compression damage to the tube. At the same time, the six cam fixing members 403 apply pressure from different directions to achieve 360-degree circumferential fixation of the endoscope tube, preventing slippage or shaking. Furthermore, the rubber clamping sleeve 404 is located between the rear end face of the knob block 4 and the front end face of the mouth fixator 1, and they are in close contact. Therefore, the rubber clamping sleeve 404 will lock and limit the knob block 4, thereby locking the position of the rotating shaft 402 and preventing the cam fixing member 403 from rotating due to external forces such as the patient's swallowing, ensuring continuous and stable fixation force.
