Description

Technical Field

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

[0002] A nasogastric tube is also called a nasogastric feeding tube, which is usually a flexible, long tube. In clinical medicine, when a patient is in a coma, has oral and cervical disease, or has difficulty swallowing due to surgery and cannot eat through the mouth, the patient can be fed through a nasogastric tube. Food is delivered to the patient's stomach through the nasogastric tube to provide the patient with necessary food and nutrition.

[0003] The existing nasogastric tube fixing device is generally fixed to the nose with medical tape. Patents with application numbers 2020210244855, 2021217434588 and 2021204582810 all disclose adhesive tapes for fixing the gastric tube. Although the fixing structure of the gastric tube is simple, it also has some disadvantages. Since the patient's nose and cheeks are rich in glands, oil secretion is high, and sweating is easy, the tape will fall off, causing the nasogastric tube to slip easily.

[0004] In the prior art, an adjustable gastric tube fixing device (application number: 2023229144053) is also disclosed. The device solves the problems caused by the method of fixing the gastric tube by pasting. At the same time, multiple groups of adjustment components 2 are arranged at the upper and lower ends of the adjustment part 1. The adjustment component 2 includes a telescopic rod, a connecting hook seat 1, a connecting hook seat 2 and a connecting spring, which are used to adapt to different sizes of gastric tubes. However, when in use, in order to allow the gastric tube to pass through the tube hole body, it is necessary to control the telescopic rods and connecting springs of the multiple groups of adjustment components 2, and the device does not provide a structure that can uniformly adjust the contraction of multiple groups of telescopic rods and connecting springs so that the gastric tube can pass through the tube hole body smoothly. Therefore, the process of adjusting the contraction of multiple groups of telescopic rods to facilitate the gastric tube to pass through the tube hole body may consume a lot of time. Summary of the invention

DETAILED DESCRIPTION

[0032] The present application will be described in detail below with reference to the exemplary embodiments in the accompanying drawings. However, it should be understood that the present application can be implemented in a variety of different forms and should not be construed as being limited to the embodiments described herein. These embodiments are provided here to make the disclosure of the present application more complete and to fully convey the concept of the present application to those skilled in the art.

[0033] In the description of the present application, it should be understood that the terms "center", "lateral", "longitudinal", "front", "back", "left", "right", "up", "down", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the scope of protection of the present application.

[0034] In view of the defect of the prior art that it takes a long time to fix the gastric tube, the inventors conducted a careful analysis and found that the main reason for the above problem is an adjustable gastric tube fixing device disclosed in the prior art. The patent specification discloses that "the medical staff inserts one end of the gastric tube into the tube hole body. At this time, the telescopic rod and the connecting spring provided between the connecting hook seat 1 and the connecting hook seat 2 can be used to adjust the gastric tube according to the different sizes of the gastric tube, so that the gastric tube can be clamped and fixed harmoniously, and finally the gastric tube can be inserted into the nasal cavity." It also discloses that "multiple groups of adjustment parts 2 are designed to greatly improve the adjustable fixing effect of the gastric tube." Combined with the attached drawings, it can be seen that the adjustment part 2 is a circle distributed at the top and bottom of the tube hole body, and an inner diameter is formed by a circle of clamping arc blocks, and the inner diameter is smaller than the outer diameter of the gastric tube, so that the gastric tube can be fixed. Before the gastric tube passes through the tube hole body, the telescopic rod needs to be retracted to expand the inner diameter of a circle of clamping arc blocks. However, these adjustment parts at the top and bottom of the tube hole body are independent, and there is no device or structure to uniformly control the retraction of the telescopic rod. When operating, medical staff may hold the tube hole body in one hand and the gastric tube in the other hand, and may not be able to adjust these telescopic rods to retract at the same time. If the telescopic rods cannot be retracted, the gastric tube may not be inserted. Therefore, the process of adjusting the retraction of multiple groups of telescopic rods to facilitate the gastric tube to pass through the tube hole body may take a lot of time. Based on the above analysis, the inventor has made structural improvements to the device for fixing the gastric tube.

[0035] like Figure 1 As shown, in one embodiment of the stomach tube fixing device of the present application, the device comprises:

[0036] A wearing component is used to wear the device on the patient's head. The wearing component includes a facial fixing component adapted to the patient's face. A strap 2 for adjusting tightness is connected to the rear end of the facial fixing component. The strap 2 has a certain width. An ear avoidance hole 21 is provided on the side of the strap 2 for the ear to pass through to prevent compression.

[0037] And a fixing component 3, used for fixing the gastric tube, the fixing component 3 comprises:

[0038] The base component 31 arranged at the bottom of the facial fixing part is preferably made of plastic material, and the connection method can be selected from glue bonding or hot melt connection. Figure 2 , 45. The base assembly 31 includes a first bottom plate 311 which is arranged transversely and is rectangular and has a certain thickness. The front end of the first bottom plate 311 is connected to a second bottom plate 312 which is rectangular and has a certain thickness. The left and right ends of the second bottom plate 312 are respectively connected to forward-bending clamping plates 313, which are thicker than the second bottom plate 312. The front end of the clamping plate 313 is provided with a countersunk hole extending backwards, and the inner wall of the countersunk hole is movably connected with a swinging member 314. The outer side surface of the clamping plate 313 is provided with a clamping groove 3131 which is connected to the countersunk hole, and the rear end of the swinging member 314 can be controlled to enter the clamping groove 3131.

[0039] And a pressing and fixing component 32 is arranged at the front end of the base component 31, and the pressing and fixing component 32 is preferably made of plastic material. Figure 3 , 4 5, which comprises a first pressing plate 321 arranged transversely and a second pressing plate 323 arranged longitudinally, the left and right ends of the first pressing plate 321 are respectively bent backward to form a clamping plate 322, the rear end of the clamping plate 322 is connected with an integrally formed hook body 3221, the second pressing plate 323 is composed of two pieces, which are distributed on the left side and the right side of the middle part of the first pressing plate 321, and the front end of the first pressing plate 321 is provided with a through hole for the first pressing plate 321 to pass through, and the first pressing plate 321 is movably passed through the through hole at the front end of the first pressing plate 321 and placed in the countersunk hole of the clamping plate 313;

[0040] The stomach tube fixing assembly 33 is disposed between the second bottom plate 312 and the first pressing plate 321, and includes a rectangular support block 335 and a fixing block 334 made of plastic. The support block 335 is disposed on the second bottom plate 312. Figure 4 The fixing block 334 is located at the front end of the supporting block 335, and the opposite end faces of the supporting block 335 and the fixing block 334 are respectively provided with arc grooves. The gastric tube is arranged in the arc groove between the supporting block 335 and the fixing block 334. A telescopic rod 332 is provided at the front end of the fixing block 334, and a through hole is provided at the front end face of the first pressing plate 321. The telescopic rod 332 relies on the through hole to move through the first pressing plate 321. A spring 333 is sleeved on the telescopic rod 332, and the spring 333 is located between the fixing block 334 and the first pressing plate 321.

[0041] The gastric tube fixing assembly 33 may be composed of two groups.

[0042] The first pressing plate 321 is pressed, and the rear end surface of the first pressing plate 321 presses the spring 333, so that the rear end of the spring 333 presses the fixing block 334 to move in the direction of the supporting block 335, and the fixing block 334 and the supporting block 335 press the outer wall of the gastric tube against each other, thereby fixing it. The greater the degree of contraction of the spring 333, the tighter the contact between the supporting block 335 and the gastric tube. When the first pressing plate 321 moves backward, the clamping plate 322 also moves with it, and the hook body 3221 of the clamping plate 322 will be clamped into the clamping groove 3131 of the clamping plate 313, preventing the elastic force of the spring 333 from pushing the first pressing plate 321 forward and causing the fixing block 334 to loosen. Figure 4 and Figure 5 As shown, the gastric tube is fixed by pressing once; Figure 6 As shown, by pressing the second pressing plate 323, the second pressing plate 323 will push the swing member 314 backward to swing, and the rear end of the swing member 314 enters the card slot 3131 from the countersunk hole of the card plate 313, pushing the hook body 3221 out of the card slot 3131, as shown in FIG. Fig. 9 As shown, the second pressing plate 323 is then released, and the spring 333 pushes the first pressing plate 321 forward, so that the hook 3221 is away from the slot 3131. After the spring 333 is not squeezed, it will not apply pressure to the fixing block 334, and the fixing block 334 is released accordingly, so that the gastric tube is not fixed, and the gastric tube is released by pressing once.

[0043] The facial fixing part includes a facial fixing frame 1 and a nose bridge plate 12. The facial fixing frame 1 is similar to the structure of a mirror frame. In this embodiment, a swimming goggles frame without lenses is used. The swimming goggles frame is relatively large in size, and the pressure is generally distributed on the cheekbones and the bridge of the nose, and will not press on the eye sockets. In order to reduce the pressure on the face caused by the facial fixing frame 1, the top of the swimming goggles frame is removed, so that the facial fixing frame 1 is roughly W-shaped, reducing the pressure on the forehead. Ear holes 11 are opened on the left and right sides of the facial fixing frame 1, and the two ends of the elastic strap 2 are respectively tied to the two ear holes 11; the nose bridge plate 12 is a transparent plastic sheet, which is similar in shape to a human nose and larger in size than the nose, and is installed in the middle of the bottom of the facial fixing frame 1, and the bottom of the nose bridge plate 12 is not blocked. When the patient uses the wearing assembly, he puts on the facial fixing part, and then the nose bridge plate 12 covers the nose.

[0044] Among them, the base component 31 is arranged at the bottom of the nose bridge plate 12, that is, the top surface of the first bottom plate 311 and the bottom surface of the nose bridge plate 12 are fixedly connected by glue or hot melt.

[0045] According to the description of the above scheme, the first base plate 311 is located in front of the patient's upper lip, and when the first pressure plate 321 or the second pressure plate 323 is pressed, a pressure is applied toward the upper lip. In order to prevent the base assembly 31 from pressing the upper lip during the pressing process, the first base plate 311 is longer than the second base plate 312. In this way, when the thumb is used to press the first pressure plate 321 or the second pressure plate 323, the index finger can be used to hold the left and right ends of the first pressure plate 321, and then force can be applied to offset the force of the thumb with the force of the index finger to avoid pressing the upper lip.

[0046] The function of the swing member 314 is to push open the hook 3221 in the slot 3131 of the card plate 313. Figure 4 and Figure 5 The swinging member 314 includes a small angle plate, the rear end of which is bent to the left (the angle plate in the card plate 313 at the right end of the second bottom plate 312 is bent to the right), and the front end of the angle plate is connected to a vertical shaft 3141, which is hingedly connected to the top and bottom surfaces of the countersunk hole through the shaft 3141. The hinge point between the shaft 3141 and the countersunk hole of the card plate 313 should be located in front of the slot 3131, and when the swinging member 314 is swung, the bent portion of the angle rod can be placed in the slot 3131 to push the hook body 3221 open.

[0047] Considering that the swing angle of the swing member 314 is a circular arc trajectory, if the shape of the slot 3131 is rectangular, it may interfere with the swing member 314 entering the slot 3131. Figure 5 As shown, the rear end of the slot 3131 is inclined toward the middle of the counterbore to form an inclined surface. When the rear end of the swing member 314 enters the slot 3131, the opening of the slot 3131 toward the outside is completely sealed, and the hook body 3221 is pushed open.

[0048] The hook body 3221 is used to limit the spring 333 from pushing the first pressure plate 321 forward, so the hook body 3221 is arranged on the inner side of the clamping plate 322 (i.e., toward the clamping plate 313) and protrudes, and its front end surface is a plane, and the inner side of the hook body 3221 is inclined backward and connected to the outer side of the clamping plate 313. When the hook body 3221 is clamped into the clamping slot 3131, the front end surface of the hook body 3221 contacts the front end surface of the clamping slot 3131.

[0049] Since most of the structure of the device is made of plastic, there will be a certain amount of wear during use. This means that when the rear end of the swinging member 314 enters the slot 3131, there may be a gap between the swinging member 314 and the slot 3131, and the edge formed by the front end face and the inner side face of the hook body 3221 may be stuck in the gap, so that the hook body 3221 cannot be separated from the slot 3131. In order to solve this problem, the edge formed by the front end face and the inner side face of the hook body 3221 can be set to an arc shape, and the size of the arc is larger than the aforementioned possible gap, so that the hook body 3221 cannot enter the gap, thereby ensuring that the hook body 3221 can be separated from the slot 3131.

[0050] In order to enable the second pressing plate 323 to push the swinging member 314 to swing, the end of the second pressing plate 323 is located in front of the swinging member 314. When the second pressing plate 323 is pressed, its end contacts the side wall of the swinging member 314 and pushes the swinging member 314 to swing.

[0051] As a component that pushes open the hook body 3221 in the slot 3131, the swinging member 314 needs to have the function of swinging and also needs to be reset as much as possible to avoid being stuck in the slot 3131, which would prevent the hook body 3221 from entering the slot 3131 during operation. In order to reset the swinging member 314, a groove is provided at the front end of the angle plate to form a space between the rotating shaft 3141 and the angle plate. A torsion spring 15 is sleeved on the rotating shaft 3141 at this position. The legs at both ends of the torsion spring 15 are fixedly connected with the inner wall of the countersunk hole where the slot 3131 is provided with glue at one end, and fixedly connected with the side of the long side of the angle plate, and with the side facing the slot 3131, at the other end. Figure 5 and Figure 7 The second pressure plate 323 is pressed backward to the right side of the swinging member 314 (the second pressure plate 323 on the right side of the middle of the first pressure plate 321 is pressed backward to the left side of the swinging member 314 in the countersunk hole of the clamping plate 313 on the right side of the second bottom plate 312), and then the swinging member 314 is swung toward the clamping direction around the axis of the rotating shaft 3141. When the second pressure plate 323 moves forward, it gradually separates from the swinging member 314, and the swinging member 314 is reset by the right-angle reaction force connected by the torsion spring 15 and the side of the long side of the angle plate.

[0052] In order to prevent the clamping plates 322 at the left and right ends of the first pressure plate 321 from falling off the two clamping plates 313, limiting grooves 3132 are respectively provided on the opposite end faces of the two clamping plates 313 and the clamping plates 322. The limiting grooves 3132 extend from the rear end of the side of the clamping plate 313 to the front end of the clamping groove 3131 and do not penetrate the front end of the clamping plate 313, so that the front end of the limiting groove 3132 forms a limiting surface. When the clamping plate 322 moves forward to the end position, the front end surface of the hook body 3221 will contact the limiting surface at the front end of the limiting groove 3132, limiting the hook body 3221 from falling off, thereby preventing the clamping plate 322 from falling off the clamping plate 313.

[0053] The support block 335 and the fixing block 334 fix the gastric tube by applying pressure, but since the size of the arc grooves opened by the two is fixed, they cannot fix gastric tubes of different sizes. In order to improve the adaptability of the device, trapezoidal fixing grooves are respectively opened in the arc grooves of the support block 335 and the fixing block 334. An arc-shaped rubber pad 336 is installed in the arc groove. On the end faces opposite to the rubber pad 336 and the arc groove, fixing wedges matching the trapezoidal fixing groove are distributed. These fixing wedges are stuck in the fixing groove to prevent the rubber pad from falling out. The thicker the rubber pad is, the smaller the gastric tube can be fixed. On the contrary, the thinner the rubber pad is, the larger the gastric tube can be fixed, so as to clamp and fix gastric tubes of different sizes.

[0054] Since the second pressing plate 323 is a thin plate, in order to avoid excessive concentrated pressure when the thumb presses and thus causing damage to the thumb, a touch rib 3231 is provided on the front end surface of the second pressing plate 323. The touch rib 3231 has a certain width, and its front end surface is preferably arc-shaped.

[0055] When patients use a gastric tube, they often develop pressure sores and other compression injuries in the nasal cavity. This problem occurs when the gastric tube is in contact with the inner wall of the nasal cavity for a long time. This device can also reduce the long-term contact between the gastric tube and the inner wall of the nasal cavity. Figure 2 and Figure 4 As shown, a sinking groove 3122 with a length is provided on the front end surface of the second bottom plate 312, and a first stroke groove 3121 is provided on the top surface and the bottom surface of the sinking groove 3122, respectively. The support block 335 is arranged in the sinking groove 3122, and a convex rib is provided on the top surface and the bottom surface of the support block 335, respectively. The convex rib is placed in the first stroke groove 3121 provided on the top surface and the bottom surface of the sinking groove 3122, respectively, to prevent the support block 335 from escaping from the sinking groove 3122. Accordingly, a through hole for the telescopic rod 332 to pass through is provided on the first pressing plate 321, and the through hole has a certain length, forming a structure as shown in FIG. Figure 3The second stroke slot 3211 shown can make the telescopic rod 332 move left and right by a certain distance. The front end of the telescopic rod 332 is provided with a limiting flange 331 to prevent the telescopic rod 332 from coming out of the second stroke slot 3211. The stomach tube is placed between the support block 335 and the fixing block 334, and the degree of compression between the stomach tube and the inner wall of the nasal cavity is checked. Then, the positions of the support block 335 and the fixing block 334 are adjusted left and right to reduce the contact between the stomach tube and the inner wall of the nasal cavity, and then the stomach tube is fixed. Such a setting can only adjust the position of the support block 335 and the fixing block 334 without adjusting the position of the entire device, which is relatively convenient and efficient to adjust.

[0056] This embodiment provides a method for using a gastric tube fixing device, comprising the following steps:

[0057] Step 1: Wear the device on the patient's head through the wearing assembly so that the fixing component 3 is located below the nose and in front of the upper lip;

[0058] Step 2: At this time, the fixing part 3 is an opening device, and the gastric tube is passed through the bottom of the fixing part 3 and enters the patient's stomach along the nasal cavity;

[0059] Step 3: Press the first pressing plate 321, the first pressing plate 321 drives the clamping plate 322 and the hook body 3221 to move backward, and at the same time, the first pressing plate 321 presses the spring 333, so that the pressing block generates pressure to press the gastric tube, and when the hook body 3221 enters the slot 3131 of the clamping plate 313, there will be a clicking sound, and then the first pressing plate 321 is released, and the spring 333 will push the first pressing plate 321 forward, so that the front end surface of the hook body 3221 and the front end surface of the slot 3131 are in contact with each other to form a limit, thereby completing the fixation of the gastric tube. The effect is as follows: Figure 2 As shown;

[0060] Step 4: Press the second pressing plate 323 to move backward, the rear end of the second pressing plate 323 contacts the side of the swinging member 314, and pushes the swinging member 314 to move toward the slot 3131 of the clamping plate 313, so that the end of the swinging member 314 pushes the hook 3221 out of the slot 3131, and the effect is as follows: Figure 6 and Figure 7 As shown;
