Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a helmet for preventing gastric tube removal. Background Art

[0002] The main function of the gastric tube is to provide adequate water and nutrition to patients who cannot swallow. Gastric juice can also be extracted through the gastric tube. The gastric tube is composed of a tube, a gastric tube feeding port connector, a gastric tube clamp, and a cross-knot plug cap. The cross-knot syringe connector of the gastric tube generally has two entrances. To open the upper plug, you can only manually pressurize the small syringe piston to inject some liquid food like water. The lower part can be injected with a booster and a large syringe to inject some thicker meat and vegetable foam, or mechanically crushed noodles, etc., but there must be no large particles that will block the tube. It should be blocked immediately after feeding. The nasogastric tube needs to be inserted through the nostrils, through the pharynx, and through the esophagus to reach the stomach.

[0003] In actual operation, in order to prevent the tube from aging or even breaking due to corrosion, it is necessary to replace the nasogastric tube regularly. Currently, most of the fixing parts use two sets of mutually rotating clamps and buckle assemblies to fix and loosen the nasogastric tube. When replacing the nasogastric tube, the clamp needs to be loosened and then the nasogastric tube is pulled out. During the process of pulling out the nasogastric tube, the operator may operate at an incorrect angle, causing the nasogastric tube to rub against the inner wall of the patient's nasal cavity or stomach, causing damage to the inner wall of the nasal cavity or stomach, and causing discomfort to the patient. Summary of the invention

[0004] In order to solve the above problems, the purpose of the utility model is to provide a gastric tube anti-extubation helmet to avoid damage caused by friction between the nasogastric tube and the inner wall of the nasal cavity or stomach when the gastric tube is removed or inserted, thereby reducing the patient's discomfort when replacing the gastric tube.

[0022] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] like Figure 1-7A stomach tube anti-extubation helmet, comprising a skull fixing helmet 1, a stomach tube fixing piece 2 detachably connected to the bottom end of the skull fixing helmet 1, and a stomach tube 3 matched with the stomach tube fixing piece 2; the stomach tube fixing piece 2 comprises a plug-in piece 21 plugged into the skull fixing helmet 1, a fixing block 22 fixed at the bottom of the plug-in piece 21, a rotating ring 23 whose upper end is screwed to the fixing block 22 and whose lower end extends to the outside of the bottom end of the fixing block 22, and an elastic clamp 24 symmetrically fixed on both sides of the upper end of the rotating ring 23 and located inside the fixing block 22; the fixing block 22 is penetrated by a through hole, and the through hole is provided A snap-in groove 221 is provided on the side wall of the hole, and the top of the side wall of the snap-in groove 221 is an inclined end 222 that is uniformly inclined outward, and the bottom is a threaded end 223 that is screwed to the rotating ring 23. The two elastic clips 24 are both against the inclined end 222 of the snap-in groove 221 on the side away from each other, and are against the outer wall of the gastric tube 3 on the side close to each other; the connector 21 includes a plug-in end 211 that is plugged into the skull fixation helmet 1 and a fixed end 212 that is symmetrically fixed to the bottom of the plug-in end 211; the two fixed ends 212 are inclined outward and the bottom ends are close to each other and are fixed to the fixing block 22.

[0024] Through the cooperation of the connector 21, the fixing block 22, the rotating ring 23 and the elastic clamp 24, it can be achieved that when the rotating ring 23 drives the elastic clamp 24 to rotate to the lowest end, the elastic clamp 24 releases the fixation of the gastric tube 3, and when the rotating ring 23 drives the elastic clamp 24 to rotate to the top, the two elastic clamps 24 clamp the gastric tube 3, so that the gastric tube 3 is fixed, and the operation is simple; through the cooperation of the fixing block 22 and the rotating ring 23, it can be achieved that when the rotating ring 23 drives the elastic clamp 24 to rotate to the bottom end, the gastric tube 3 can easily slide from the gastric tube fixing part 2 while being limited by the clamping groove 221 of the fixing block 22, so that the gastric tube 3 can only move along the clamping groove 22 1, so as to avoid the friction between the gastric tube 3 and the inner wall of the nasal cavity or stomach of the patient due to the operation of the operator when the gastric tube 3 is inserted and removed, and to avoid the damage to the inner wall of the nasal cavity or stomach caused by the insertion and removal of the gastric tube 3, thereby alleviating the discomfort of the patient; through the arrangement of the plug-in end 211 and the fixing end 212, on the one hand, it can be prevented that the plug-in part 21 is too much higher than the patient's face, thereby reducing the possibility of the gastric tube fixing part 2 being misactivated when the operator passes over the patient's face, thereby reducing the possibility of the gastric tube 3 moving in the nasal cavity and stomach, and improving the firmness of the device to fix the nasal tube 3; on the other hand, the fixing block 22 can be fixed from both sides, thereby improving the stability of the fixing of the fixing block 22.

[0025] like Figure 3As a possible implementation of the present scheme, preferably, the head fixation helmet 1 is provided with a slide groove 11 adapted to the plug-in end 211, and the side walls of the slide groove 11 are spaced apart with adjustment slots 12, and the plug-in end 211 is provided with an adjustment block 213 adapted to the adjustment slot 12 on the outside; through the cooperation of the adjustment slot 12 and the adjustment block 213, on the one hand, the gastric tube fixing part 2 can be quickly replaced to improve the service life of the device, and on the other hand, the positions of the fixing block 22, the rotating ring 23 and the elastic clamp 24 can be adjusted independently, so that the gastric tube fixing part 2 is more closely fitted to the patient's nose, thereby improving the comfort when using the device and the firmness of the device to fix the gastric tube 3.

[0026] like Figure 3-5 As a possible implementation of the present solution, preferably, a protrusion 231 is fixed on the surface of the rotating ring 23 ; the setting of the protrusion 231 can facilitate the operator to rotate the rotating ring 23 .

[0027] like Figure 6-7 As a possible implementation of the present scheme, preferably, the gastric tube fixing device 2 also includes a secondary limiting component; the secondary limiting component includes a mounting block 25 symmetrically arranged at the bottom of the fixing block 22 and a spring telescopic rod 26 fixed to the mounting block 25 on one side close to the skull fixation helmet 1, and a plurality of limiting grooves 13 adapted to the driving end of the spring telescopic rod 26 are provided on both sides of the skull fixation helmet 1; through the cooperation between the spring telescopic rod 26 and the limiting groove 13, the firmness of the fixation between the device and the patient's head can be increased, and the possibility of movement of the gastric tube fixing device 2 can be reduced, thereby reducing the possibility of injury to the patient when using the gastric tube 3.

[0028] The working principle of this device is:

[0029] When using the device, first put the skull fixation helmet 1 on the patient's head, insert the plug-in end 211 of the connector 21 into the slide groove 11 and slide it until the through hole of the fixing block 22 is opposite to the patient's nostril. At this time, the adjustment block 213 is engaged with the corresponding adjustment groove 12, and the two spring telescopic rods 26 are engaged with the corresponding limit grooves 13. Then, the gastric tube 3 is passed through the rotating ring 23, between the two elastic clips 24 and the fixing block 22 in sequence until it enters the patient's body. Finally, the rotating ring 23 is rotated toward one side of the fixing block 22, so that the tops of the two elastic clips 24 move toward each other under the action of the inclined end 222 of the fixing block 22, thereby clamping the gastric tube 3; when the gastric tube 3 needs to be removed, the rotating ring 23 is rotated in the opposite direction so that the tops of the two elastic clips 24 move away from each other, so as to achieve the release of the gastric tube 3 by the two elastic clips 24.

[0030] The above description is only a specific implementation method of the utility model, and does not limit the patent scope of the utility model. Any equivalent structural transformation made using the contents of the utility model specification and drawings, or directly or indirectly used in other related technical fields, are also included in the patent protection scope of the utility model.
