Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of nasogastric tube fixation, in particular to a gastric tube fixing device. BACKGROUND

[0002] The gastric tube is also called nasogastric tube or nasogastric feeding tube. The gastric tube reaches the stomach from the pharynx through the esophagus. The gastric tube is generally used to extract gastric juice and can be used to inject liquid into the stomach to provide necessary food and nutrition for patients. During nursing, attention should be paid to avoid gastric tube pollution and gastric tube prolapse, which may cause aspiration.

[0003] At present, after the gastric tube enters the body through the patient's nasal cavity, it is generally adhered to the patient's alae nasi and cheek by adhesive tape to achieve fixation of the gastric tube. After long-term use, the patient's alae nasi and cheek secrete more oil, and sweating makes the adhesive tape lose adhesion quickly. In addition, the patient wearing the gastric tube feels uncomfortable and may unconsciously shake the head. If the adhesive tape loses adhesion, the gastric tube is easily slid out of the nasal cavity during the patient's shaking. CONTENT OF THE UTILITY MODEL

[0028] ​To address the drawback of existing technologies where nasogastric tubes easily slip out of the nasal cavity, the inventors, after careful analysis, discovered that the main reason for this problem lies in the fact that current methods of securing nasogastric tubes typically involve attaching them to the patient's nose with adhesive tape. For example, a prior art nasogastric tube fixation device (application number: 202223096883X) uses an adhesive part to adhere to the skin at the bridge of the nose, and a clamping part to conveniently fix the nasogastric tube or nasoenteric tube, which is in a suspended state, effectively reducing pressure injuries to the skin inside the nasal cavity and lowering patient discomfort. However, in practice, this still involves using adhesive structures like tape to fix the tube to the patient's nose. The T-zone (forehead and nose) is one of the areas with the highest density of sebaceous glands on the face. Due to frequent nasal breathing, airflow removes more moisture, causing the sebaceous glands to secrete more oil to maintain hydration. These oils can reduce the fit between the adhesive patch and the bridge of the nose. Furthermore, when a patient wears a gastric tube, due to the invasive nature of the procedure, the tube passes through the narrow passages of the nasal cavity, pharynx, and esophagus. These areas have a dense distribution of nerve endings in the mucous membranes, and the physical friction of the tube can directly cause pain, a foreign body sensation, or a feeling of suffocation. Therefore, patients often physiologically turn their heads to try and relieve this discomfort. If the adhesive patch and the oil on the bridge of the nose come into contact and detach, the gastric tube can easily slip out of the nasal cavity when the patient shakes their head. Based on the above analysis, the inventors improved the structure for securing the gastric tube.

[0029] like Figures 1-3 As shown, in at least one embodiment of a gastric tube fixation device of this application, a fixation component for fixing to the patient's face and a clamping component for clamping and fixing the gastric tube are included.

[0030] The fixing component includes an arc-shaped rod 1 that fits the face. The arc-shaped rod 1 is preferably a rod with a rectangular cross-section. Both ends of the arc-shaped rod 1 contact the patient's face, and the contact position can be the cheekbone and the surrounding area. The inner wall of the middle part of the arc-shaped rod 1 (which can also be understood as the rear end) is connected to a rectangular sheet-like connecting rib 13. The rear end of the connecting rib 13 is connected to a nasal bridge support block 4 for mounting on the patient's nasal bridge. The structure of the arc-shaped rod 1 and the nasal bridge support block 4 is similar to that of eyeglasses. At both ends of the arc-shaped rod 1, there are fixing parts for fixing the fixing component to the face. The fixing parts include an adhesive part that is glued to the patient's face and an ear fixing part that is clamped on the patient's ear.

[0031] The clamping assembly is located at the bottom of the arc-shaped rod 1. The clamping assembly includes a rectangular, vertically arranged connecting plate 6. Below the rear end of the connecting plate 6 is a square chamber 7 with a rearward opening. The chamber 7 is formed by splicing four square plates. The chamber 7 contains a clamping part for clamping the gastric tube 17. Figures 1-3The right side of the chamber 7 is provided with an adjusting rod 9, wherein the left and right sides of the chamber 7 and the side walls of the clamping part are respectively provided with holes for the adjusting rod 9 to pass through, the adjusting rod 9 passes through the holes on the clamping part from the right side of the chamber 7 in sequence and passes out from the hole on the left side of the chamber 7, the adjusting rod 9 can rotate in the holes on the side of the chamber 7 and the side of the clamping part, and the right side of the clamping part and the adjusting rod 9 are provided with a spring 15.

[0032] The rear end of the nose bridge support block 4 is arc-shaped, which is inclined forward to adapt to the bridge of the patient's nose.

[0033] The adhesive part is used to fix the fixing assembly on the patient's face by adhesion and clamping, and the adhesive part includes a pair of suction cups 2, and the ear fixing part includes a pair of ear hoops 3, the two suction cups 2 are respectively fixedly connected to the two ends of the arc-shaped rod body 1, and the suction ends of the suction cups 2 face the face, and the two ear hoops 3 are respectively fixedly connected to the outer walls of the two ends of the arc-shaped rod body 1. The ear hoops 3 can be general rubber hoops or rubber rings.

[0034] Considering that the suction cups 2 may lose the adsorption force due to the gap, the inner walls of the suction cups 2 are provided with adhesive layers, and the adhesive layers can adopt the adhesive on the ostomy base plate, which generally includes an inner acrylic pressure-sensitive adhesive ring, a thick hydrocolloid adhesive ring and an outer acrylic pressure-sensitive adhesive ring from inside to outside, or an inner acrylic pressure-sensitive adhesive ring, a middle hydrocolloid adhesive ring and an outer acrylic pressure-sensitive adhesive ring or hydrocolloid adhesive ring. The combination utilizes the water-repellent and corrosion-resistant properties of the acrylic pressure-sensitive adhesive and the good adhesion and water absorption of the hydrocolloid. The initial adhesion and holding adhesion are good, the adhesion is firm and the tearing is convenient. At the same time, the allergy rate is low, which can protect the skin and reduce the occurrence of eczema. The combination of the suction cups 2 and the adhesive layers adsorbed on the patient's face can increase the stability of the fixing assembly on the face, and then the combination of the ear hoops 3 worn on the ears can pull the fixing assembly and also increase the stability of the fixing assembly on the face.

[0035] The clamping part is used to clamp the gastric tube 17 to prevent the gastric tube 17 from moving, and the combination of the clamping part and the adjusting rod 9 can adjust the length of the fixing assembly. Figure 1 and Figure 3 The clamping part includes a left clamping part 14 and a right clamping part 8, the left clamping part 14 includes a first clamping plate 141 and a first wrapping plate 142, and the rear ends of the first clamping plate 141 and the first wrapping plate 142 are fixedly connected, and the right clamping part 8 includes a second clamping plate 81 and a second wrapping plate 82, and the rear ends of the second clamping plate 81 and the second wrapping plate 82 are fixedly connected.

[0036] The holes on the clamping part for the adjusting rod 9 to pass through are respectively provided on the side walls of the first clamping plate 141 and the second clamping plate 81.

[0037] The first clamping plate 141 is fixedly connected with the inner wall of the chamber 7, so that the left clamping member 14 cannot move left and right, and the second clamping plate 81 is movably sleeved on the adjusting rod 9, the adjusting rod 9 is provided with two flanges 92 for driving the second clamping plate 81 to move left and right, so that the right clamping member 8 can move, thereby realizing the opening and closing of the clamping part.

[0038] The first wrapping plate 142 and the second wrapping plate 82 are preferably in an arc-shaped structure, so that the area of wrapping the gastric tube 17 is larger, and an arc-shaped rubber pad 16 can be arranged on the inner wall of the first wrapping plate 142 and the second wrapping plate 82. The rubber pad 16 can generate greater friction than hard plastic through contact and extrusion with the gastric tube 17, and can clamp the gastric tube 17 more stably.

[0039] The front end of the arc-shaped rod body 1 can also be provided with a plastic U-shaped fixing clamp 10, as shown in Figure 4 When the clamping part clamps the gastric tube 17, the gastric tube 17 is hung in the fixing clamp 10, forming double fixation, and further improving the stability of the gastric tube 17, preventing the gastric tube 17 from slipping out of the nasal cavity.

[0040] In this embodiment, the clamping assembly is arranged below the arc-shaped rod body 1. Considering different patients wearing, if the clamping assembly is fixed at the only position at the bottom of the arc-shaped rod body 1, when the nasal cavity of the patient and the clamping assembly are misaligned, the gastric tube 17 may press against the inner wall of the nasal cavity, causing pressure sores. In order to solve the above problems, referring to Figure 5 and Figure 6 A reverse convex-shaped sliding groove penetrating through the bottom of the arc-shaped rod body 1 is arranged at the bottom of the arc-shaped rod body 1, and a square convex edge 61 is arranged at the top of the connecting plate 6 (since the sliding groove is arc-shaped, the connecting plate 6 and the convex edge 61 are also arc-shaped, so that the connecting plate 6 and the convex edge 61 can move in the sliding groove), as shown in Figure 1 A adjusting window 11 communicating with the sliding groove is arranged at the front end of the arc-shaped rod body 1, and a threaded through hole is arranged on the connecting plate 6, and an adjusting screw 5 is arranged in the adjusting window 11, and the adjusting screw 5 is screwed in the threaded through hole. After the clamping assembly is moved to a suitable position in the sliding groove, the adjusting screw 5 is tightened, one end of the adjusting screw 5 abuts against the inner wall of the sliding groove, and the connecting plate 6 drives the convex edge 61 to move forward along the thread of the adjusting screw 5 until the connecting plate 6 abuts against the inner wall of the front end of the sliding groove. When the adjusting screw 5 is locked, the clamping assembly is fixed at the position.

[0041] The length of the adjusting window 11 can be used to adjust the clamping assembly to below the left nasal cavity or the right nasal cavity.

[0042] Some existing stomach tube 17 fixers usually use threaded connection to press the stomach tube 17 to fix the stomach tube 17, such as a stomach tube 17 fixer (application number: 2022208739793), which fixes the stomach tube 17 in the movable groove by screwing the clamping block to tightly press the stomach tube 17. Since the fixer is installed near the patient's nose, it cannot directly rotate the threaded column by a large amplitude by simply using the screwing method. Moreover, when installing or removing the stomach tube 17, the threaded seat needs to be completely rotated to the right end. Therefore, when installing, fixing or removing the stomach tube 17, it may need to be rotated several times to completely fix the stomach tube 17, and the fixing efficiency is low.

[0043] In the present embodiment, reference is made to Figure 2 and Figure 3 The clamping assembly has the function of fixing the stomach tube 17 and can also quickly install or remove the stomach tube 17. The right clamping piece 8 is driven by the adjusting rod 9. When the thread on the adjusting rod 9 is away from the screw hole on the left side of the cavity, the right end of the adjusting rod 9 can be pulled or the left end of the adjusting rod 9 can be pressed, and the adjusting rod 9 will move to the right. The flange 92 on the adjusting rod 9 and the left side of the second clamping plate 81 will push the right clamping piece 8 to move to the right (at this time, the spring 15 is in a compressed state), and the clamping part is opened. The stomach tube 17 in the clamping part can be quickly removed or the stomach tube 17 can be quickly placed in the clamping part. Then, the adjusting rod 9 is loosened, and the spring 15 on the adjusting rod 9 will push the second clamping plate 81 of the right clamping piece 8 to move to the left and push the left flange 92, drive the adjusting rod 9 to move to the left, and make the right clamping piece 8 close to the left clamping piece 14. The clamping part is closed. If there is a stomach tube 17 in the clamping part, i.e. the stomach tube 17 is clamped, at this time, the thread on the adjusting rod 9 is returned to the right side of the screw hole on the left side of the cavity 7. Only half a turn or one turn of the adjusting rod 9 is needed to make the right clamping piece 8 move to the left by a certain distance, so that the stomach tube 17 can be tightly clamped by the threaded method. The efficiency of installing and removing the stomach tube 17 is very high.

[0044] In addition, in order to facilitate the rotation of the adjusting rod 9, round knobs 91 are connected to the left and right ends of the adjusting rod 9.

[0045] When using the device, first place the stomach tube 17 in the patient's nasal cavity, then stick the fixing assembly to the patient's face, such as the position of the cheekbone, through the suction cup 2 and the adhesive layer, and fix the nose bridge fixing piece on the nose bridge. The ear hoop 3 is put on the ear, the fixing assembly is stably attached to the patient's face, at this time, the clamping assembly is extended and arranged below the nose through the connecting plate 6, then the clamping assembly is used in the aforementioned manner to clamp and fix the stomach tube 17, and finally the position of the clamping assembly is adjusted to prevent the stomach tube 17 from pressing the inner wall of the nasal cavity to cause pressure sores.

[0046] It should be understood that all the above examples are exemplary but not limiting, and various modifications or variations of the specific embodiments described above made by those skilled in the art under the concept of the present application shall be within the protection scope of the present application.
