Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an ear-loop gastric tube fixing device. Background Technology

[0002] With the development of medical technology, people who cannot eat normally, such as those with cerebral hemorrhage, impaired swallowing function, or vegetative state, need to rely on nasogastric tubes to deliver nutrients into their stomachs. The nasogastric tube is inserted through the nostril, passes through the esophagus, and reaches the stomach. When the patient's stomach absorbs the food and nutrients delivered by the nasogastric tube, the nasogastric tube will move during the absorption and digestion process. To avoid damage caused by friction between the nasal mucosa and the nasogastric tube due to the movement of the tube, the tube is currently fixed with a nasogastric tube fixation tape.

[0003] To ensure stability, the gastric tube is usually fixed to the patient's face with tape. Since patients need to wear the gastric tube for a long time, pressure sores can easily form on the face, which is not conducive to the patient's recovery. In addition, when the patient gets up and moves, the gastric tube will swing around with the patient's movements, causing the gastric tube inserted into the patient's stomach to be pulled and causing discomfort to the patient. Utility Model Content

[0004] This invention provides an ear-hook type gastric tube fixing device to solve the problem in the prior art where the gastric tube swings around with the patient's movements when the patient gets up, causing the gastric tube inserted into the patient's stomach to be pulled and causing discomfort to the patient.

[0044] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0045] Reference Figure 1-4 The illustrated ear-loop gastric tube fixation device includes:

[0046] Ear hook 100, the ear hook 100 is adapted to be worn on the patient's ear, and a hinge frame 110 is fixedly installed on the outer side of the ear hook 100.

[0047] Rotating assembly 200 is rotatably mounted on hinge frame 110;

[0048] The rotating assembly 200 includes:

[0049] Rotating head 210 is installed inside hinge frame 110 and can rotate 180° relative to hinge frame 110;

[0050] Also includes:

[0051] The clamping device 300 is rotatably mounted on the rotating head 210 and its position relative to the ear hook 100 is adjusted under the drive of the rotating head 210.

[0052] The limiting device 400 is installed inside the hinge frame 110 and is used to limit the rotation of the rotating head 210.

[0053] The process involves opening the clamping device 300, passing the gastric tube through the clamping device 300, closing the clamping device 300 to clamp and fix it, and then placing the ear hook 100 on the patient's ear.

[0054] When it is necessary to adjust the position of the clamping device 300, pull the limiting device 400 to release the limiting device 400 from restricting the rotating head 210, so that the rotating head 210 can rotate normally and drive the clamping device 300 to adjust its position. Then push the limiting device 400 in to restrict the rotating head 210.

[0055] The ear loop 100 is placed on the ear and the clamping device 300 is used to fix the end of the gastric tube, so as to prevent the end of the gastric tube from swinging around when the patient moves, and to prevent the gastric tube inserted into the patient's stomach from being pulled and causing discomfort to the patient. At the same time, it does not stick to the patient's face, preventing pressure sores from forming on the patient's face, so as to facilitate the patient's recovery.

[0056] The rotating head 210 and the hinge frame 110 are designed to allow the clamping device 300 to be positioned on either side of the ear hook 100, so that the ear hook 100 can be placed on either ear of the patient, reducing the impact of ear discomfort.

[0057] The rotation of the rotating head 210 is limited by the setting of the limiting device 400 to prevent the rotating head 210 from rotating under the pull of external force.

[0058] In some embodiments of this utility model, in order for the limiting device 400 to be inserted normally, refer to Figure 3 As shown, the outer side of the hinge frame 110 is provided with a polygonal insertion hole 120 that is compatible with the limiting device 400.

[0059] The polygonal jack 120 ensures the normal insertion of the limiting device 400 and restricts the rotation of the limiting device 400.

[0060] In some embodiments of this utility model, in order to ensure the proper installation of the rotating head 210, refer to Figure 3 As shown, the rotating assembly 200 also includes:

[0061] A rotating shaft 220 is fixed on the rotating head 210 and inserted into the polygonal socket 120. Two rotating shafts 220 are provided.

[0062] Polygonal sleeve 230 is fixed to the outside of pivot 220 and is adapted to limit device 400.

[0063] The rotating shaft 220 ensures the normal installation of the rotating head 210 and restricts the rotation center of the rotating head 210.

[0064] The polygonal sleeve 230 is adapted to the limiting device 400, so that the limiting device 400 can properly limit the rotation of the rotating shaft 220.

[0065] In some embodiments of this utility model, in order to rotate according to the extension direction of the gastric tube, refer to Figure 4 As shown, the clamping device 300 includes:

[0066] Rotary joint 310 is rotatably mounted on rotary head 210;

[0067] The first clamping plate 320 is fixed on the rotating joint 310 and follows the rotating joint 310 to adjust the extension direction of the gastric tube.

[0068] The second clamping plate 330 clamps the gastric tube when it slides toward the first clamping plate 320. Both the first clamping plate 320 and the second clamping plate 330 are divided into two parts and fixed by bolts.

[0069] The rotating joint 310 ensures the normal installation and use of the first clamping plate 320, allowing the first clamping plate 320 to rotate relative to itself.

[0070] The gastric tube is clamped and fixed when the first clamping plate 320 and the second clamping plate 330 are in cooperation, and when they are far apart, the gastric tube can pass through the clamping device 300 normally or be removed from the clamping device 300.

[0071] In some embodiments of this utility model, in order to drive the second clamping plate 330 to slide towards the first clamping plate 320, refer to Figure 4 As shown, the clamping device 300 also includes:

[0072] Guide groove 340 is formed on the first clamping plate 320;

[0073] Guide post 350 is fixed on the second clamping plate 330 and inserted into the guide groove 340;

[0074] The first spring 360 is installed between the inner wall of the guide groove 340 and the guide post 350, and pulls the second clamping plate 330 to slide towards the first clamping plate 320. When the first spring 360 is stretched to the maximum stress, the guide post 350 is still located inside the guide groove 340.

[0075] The guide post 350 and the guide groove 340 are designed to guide the sliding of the second clamping plate 330, preventing the second clamping plate 330 from being misaligned with the first clamping plate 320 when subjected to external force, so that the first clamping plate 320 can cooperate with the second clamping plate 330 to clamp and fix the gastric tube.

[0076] The first spring 360 is stretched when the second clamping plate 330 moves outward, and after the external force on the second clamping plate 330 disappears, it drives the second clamping plate 330 to reset, so that the second clamping plate 330 is pulled to clamp the gastric tube, and the first spring 360 is always in a stored state.

[0077] In some embodiments of this utility model, in order to increase the friction with the gastric tube, refer to Figure 4 As shown, clamping channels 370 are provided on the side of the first clamping plate 320 and the second clamping plate 330 that are close to each other, and a first rubber pad 380 is bonded to the inner surface of the clamping channel 370.

[0078] Specifically, pulling the second clamping plate 330 away from the first clamping plate 320 causes the guide post 350 to slide along the guide groove 340, and stretches the first spring 360 during the sliding. Then, the gastric tube is passed through the clamping channel 370. When the tension on the second clamping plate 330 is released, the first spring 360 will pull the second clamping plate 330 back to its original position, so that the second clamping plate 330 clamps the gastric tube.

[0079] The clamping channel 370 provides space for the passage of the gastric tube, allowing the gastric tube to pass normally through the external force of the second clamping plate 330. The second clamping plate 330 will clamp and fix the gastric tube under the action of the first spring 360.

[0080] The first rubber pad 380 increases friction when the gastric tube is clamped, preventing it from slipping under external pulling and increasing its stability during use.

[0081] In some embodiments of this utility model, in order to limit the rotation of the polygonal sleeve 230, refer to Figure 3 As shown, the limiting device 400 includes:

[0082] Positioning sleeve 410, which is slidably sleeved on the outside of polygonal sleeve 230, and the internal space of positioning sleeve 410 is polygonal.

[0083] The limiting plate 420 is fixed on the positioning sleeve 410 and cooperates with the polygonal socket 120 to restrict the rotation of the positioning sleeve 410. The limiting plate 420 is polygonal and will not be completely inserted into the polygonal socket 120.

[0084] The second spring 430 is installed between the limiting plate 420 and the inner wall of the polygonal socket 120, and is stretched when the limiting plate 420 moves outward.

[0085] The positioning sleeve 410 and the limiting plate 420 are configured to restrict the rotation of the polygonal sleeve 230, and the restriction on the polygonal sleeve 230 can be released when it moves outward.

[0086] The second spring 430 is designed to stretch when the limiting plate 420 moves outward. After the external force on the limiting plate 420 disappears, the second spring 430 will drive the limiting plate 420 to reset.

[0087] In some embodiments of this utility model, in order to improve patient comfort, refer to Figure 2 As shown, the inner surface of the ear hook 100 is bonded with a second rubber pad 130 that contacts the patient's ear.

[0088] The second rubber pad 130 reduces pressure marks on the ear from the ear hook 100, improving patient comfort.

[0089] The working method of this utility model:

[0090] Pull the second clamping plate 330 away from the first clamping plate 320, and drive the guide post 350 to slide along the guide groove 340. While sliding, the first spring 360 is stretched. Then, the gastric tube is passed through the clamping channel 370. When the tension on the second clamping plate 330 is released, the first spring 360 will pull the second clamping plate 330 back to its original position, so that the second clamping plate 330 clamps the gastric tube. Then, the ear hook 100 is put on the patient's ear.

[0091] When the position of the clamping device 300 needs to be adjusted, pull the limiting plate 420 so that the limiting plate 420 drives the positioning sleeve 410 to disengage from the polygonal sleeve 230 and stretch the second spring 430. Then rotate the rotating head 210 and drive the clamping device 300 to adjust its position. When the force on the limiting plate 420 is released, the second spring 430 will pull the limiting plate 420 to reset, so that the positioning sleeve 410 is sleeved on the outside of the polygonal sleeve 230 and drives the polygonal sleeve 230.

[0092] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
