Description

Technical Field

[0001] This application belongs to the field of medical device technology, specifically a device for fixing a digestive tract drainage tube. Background Technology

[0002] Gastrointestinal drainage tubes, including gastric tubes, jejunal nasogastric tubes, and intestinal obstruction catheters, are used to address issues such as esophageal stricture, pyloric obstruction, intestinal obstruction, digestive fluid drainage, enteral nutrition support, digestive fluid drainage for patients undergoing gastrointestinal surgery, and long-term nasogastric feeding for patients with cerebrovascular diseases. For example, a nasogastric tube is a thin medical tube that enters the stomach through the esophagus from the nasal cavity, and can even reach the duodenum. It can help patients who cannot swallow food normally, allowing nutritional solutions or medications to reach the stomach or duodenum through the nasal cavity, supplementing the patient's nutrition and sustaining life.

[0003] In clinical practice, drainage tubes need to be fixed to the patient's face using adhesive tape. Because patients need to wear the drainage tube for a long time, and the drainage tube has a certain degree of elasticity, strong adhesive tape is needed to fix the drainage tube to the patient's nasolabial folds, cheeks, and other locations. However, the tape has poor breathability, and prolonged adhesion to the same skin surface can easily cause skin damage. Furthermore, the drainage tube is not easy to switch between the left and right nostrils. When the nostril with the drainage tube inserted needs to pass through the nostril without the drainage tube to reach the adhesive site, the tape's fixation effect on the drainage tube is poor. If the tape is attached to the philtrum, the tape will cause discomfort to the patient when talking, eating, or using the upper lip, and it is also easy for the tape to loosen and become contaminated. Utility Model Content

[0004] To facilitate patients in changing the placement of the dressing while ensuring effective fixation of the drainage tube, this application provides a digestive tract drainage tube fixation device.

[0005] A device for fixing a digestive tract drainage tube includes a mounting frame and a fixing sleeve that can be fitted onto the drainage tube. The mounting frame includes a connecting part that is detachably connected to the fixing sleeve, an adhesive part with an adhesive layer, and a frame body that connects the connecting part and the adhesive part. The projection of the extension direction of the frame body into the cross-section of the fixing sleeve has a first inflection point. The connecting part is slidably connected to the frame body and can move along the frame body to change the lateral distance between the connecting part and the adhesive part.

[0006] In one embodiment of this application, the frame includes a transverse bar and a longitudinal bar connected to the transverse bar, an adhesive part is connected to the longitudinal bar, and the connection between the transverse bar and the longitudinal bar forms a first inflection point; the connecting part is slidably connected to the transverse bar and can move along the transverse bar to change the transverse spacing between the connecting part and the adhesive part.

[0007] In one embodiment of this application, the digestive tract drainage tube fixing device further includes a first elastic sleeve, which can be simultaneously fitted onto the connecting part and the transverse rod, and generate a radially inward elastic force; the frictional force between the first elastic sleeve, the connecting part, and the transverse rod can restrict the movement of the connecting part along the transverse rod.

[0008] In one embodiment of this application, the digestive tract drainage tube fixing device further includes a flexible band located on the outer side of the first inflection point extension direction. One end of the flexible band is connected to the connecting part, and the other end is provided with a second elastic sleeve. The second elastic sleeve is fitted onto the longitudinal rod and can increase the distance between the connecting part and the adhesive part by means of friction between the flexible band and the longitudinal rod.

[0009] In one embodiment of this application, the fixing sleeve is snapped into the connecting part.

[0010] In one embodiment of this application, the connecting part consists of two spaced-apart claws, and the fixing sleeve can be inserted between the two claws and engaged with them.

[0011] In one embodiment of this application, the adhesive part is detachably connected to the frame.

[0012] In one embodiment of this application, the inner wall of the fixing sleeve is provided with an elastic portion, which can elastically deform along the radial direction of the fixing sleeve to change the inner diameter of the fixing sleeve.

[0013] In one embodiment of this application, the side wall of the fixed sleeve is provided with a ventilation channel, which penetrates the fixed sleeve along the axial direction of the fixed sleeve.

[0014] In one embodiment of this application, the fixing sleeve and / or the connecting portion are provided with an adhesive layer.

[0015] The beneficial effects of this application are at least as follows:

[0016] 1. The frame in this application has a first inflection point that can conform to the curve of the patient's face. Since the face is mirror-symmetrical about the sagittal plane of the human body, the first inflection point can conform to the left or right facial curve, so that the adhesive part can be pasted on the nasolabial side of the left or right side of the face. At the same time, since the connecting part and the fixing sleeve are detachably connected, when the adhesive part changes the position and the orientation of the first inflection point changes, the fixing sleeve and the connecting part can be separated before the position is changed. After the position of the adhesive part changes, the fixing sleeve and the connecting part can be reconnected. Thus, the fixing sleeve can always be connected to the drainage tube without adjusting the connection between the drainage tube and the fixing sleeve. This makes it easier to adjust the position of the adhesive part and avoids the adhesive part from being in contact with the skin in one place for a long time, which could cause skin damage due to medical adhesive.

[0017] 2. Since the connecting part is connected to the fixed sleeve with the drainage tube, the first elastic sleeve fitted on the connecting part and the transverse rod can effectively prevent the connecting part and the transverse rod from moving, thereby preventing the drainage tube from moving. At the same time, if the drainage tube is pulled by a large force due to an accident, the connecting part and the transverse rod can move relative to each other, generating a buffering effect.

[0032] See Figure 1 A digestive tract drainage tube fixing device includes a mounting frame 201 and a fixing sleeve 101 that can be fitted onto the drainage tube. The mounting frame 201 includes a connecting part 202 detachably connected to the fixing sleeve 101, an adhesive part 301 with an adhesive layer, and a frame connecting the connecting part 202 and the adhesive part 301. The adhesive layer can be made of medical adhesive so that the adhesive part 301 can be adhered to the patient's facial skin to fix the mounting frame 201 and the fixing sleeve 101, thereby fixing the drainage tube connected to the fixing sleeve 101. Furthermore, the fixing sleeve 101 and / or the connecting part 202 are provided with an adhesive layer, which is medical adhesive. The fixing sleeve 101 and the connecting part 202 can both be provided with medical adhesive, or one of the fixing sleeve 101 and the connecting part 202 can be provided with medical adhesive to adhere to the patient's skin, ensuring that the device can be firmly adhered to the patient's skin surface and reducing the possibility of the drainage tube dislodging or moving.

[0033] The projection of the extension direction of the frame in the cross section of the fixed sleeve 101 has a first inflection point 205, which allows the frame to conform to the physiological curve of the face. The connecting part 202 is slidably connected to the frame and can move along the frame to change the lateral distance between the connecting part 202 and the adhesive part 301.

[0034] See Figures 1 to 3 In one embodiment of this application, the frame includes a transverse rod 203 and a longitudinal rod 204 connected to the transverse rod 203. An adhesive part 301 is connected to the longitudinal rod 204, and a first inflection point 205 is formed at the connection between the transverse rod 203 and the longitudinal rod 204. A connecting part 202 is slidably connected to the transverse rod 203 and can move along the transverse rod 203 to change the transverse distance between the connecting part 202 and the adhesive part 301. Those skilled in the art will understand that the angle between the transverse rod 203 and the longitudinal rod 204 in this application can be adjusted according to the facial curve, allowing for the production of different models to cater to different patients. The plane of the frame's extension direction is not necessarily parallel to the cross-section of the fixing sleeve 101; that is, the axis of the fixing sleeve 101 can be perpendicular to the plane of the frame's extension direction, or it can be non-perpendicular to the plane of the frame's extension direction, adjusted according to the actual situation, so that the curve at the first inflection point 205 can conform as closely as possible to the physiological curve of the face.

[0035] The drainage tube enters the outside through one of the two nostrils, thus defining the left and right sides of the face. The side of the face closer to the drainage tube is the proximal side, and the side of the face farther from the drainage tube is the distal side. The adhesive part 301 needs to be attached to the nasolabial side. When the adhesive part 301 is switched from the proximal side to the distal side, the distance between the drainage tube and the adhesive part 301 needs to be increased because there is a nostril without the drainage tube between the nostril with the drainage tube and the adhesive part 301. Conversely, when the adhesive part 301 is attached from the distal side to the proximal side, the distance between the drainage tube and the adhesive part 301 needs to be decreased. When the adhesive part 301 needs to be switched from the left side of the face to the right side of the face, or from the right side of the face to the left side of the face, and the adhesive part 301 is switched between the proximal and distal sides of the tube, the distance between the adhesive part 301 and the fixing sleeve 101 will change. The connecting part 202 connected to the fixing sleeve 101 can move along the transverse rod 203, thereby changing the transverse distance between the adhesive part 301 and the fixing sleeve 101, and thus changing the transverse distance between the drainage tube connected to the fixing sleeve 101 and the adhesive part 301.

[0036] Simultaneously, when the installation position of the adhesive part 301 is changed, the mounting bracket 201 will rotate so that the curve at the first inflection point 205 can conform as closely as possible to the physiological curve of the face. During this process, if the fixing sleeve 101 rotates with the mounting bracket 201, the fixing sleeve 101 will bend the drainage tube. Therefore, the fixing sleeve 101 is designed to be detachably connected to the mounting bracket 201. Figure 5 , Figure 6 Examples are given based on the direction in the middle.

[0037] See Figure 4 , Figure 4 The adhesive part 301 is located on the right side of the fixing sleeve 101. The tip of the fixing sleeve 101 can be inserted into the patient's nostril. The center of the first inflection point 205 is located on the left side of the longitudinal rod 204. When the patient attaches the adhesive part 301 to the left side of the fixing sleeve 101, it is positioned as follows: Figure 5 The direction in the middle is used as a reference for description, and the fixed sleeve 101 is in Figure 5 When the patient adjusts the adhesive part 301 to the left side of the fixing sleeve 101 with the center facing upwards, the frame needs to be rotated 180° clockwise. If the fixing sleeve 101 rotates with the frame, the tip of the fixing sleeve 101 should face upwards. Figure 5 If the connecting part 202 of the frame body is separated from the fixing sleeve 101, the frame body can rotate independently relative to the fixing sleeve 101. The fixing sleeve 101 is always fitted on the drainage tube. After the frame body is adjusted, the connecting part 202 is connected to the fixing sleeve 101, so that the tip of the fixing sleeve 101 faces the center. Figure 5 The top of the direction is shown as Figure 6This is to prevent the drainage tube from bending due to the rotation of the fixing sleeve 101 caused by adjusting the adhesive part 301.

[0038] See Figures 1 to 3 In one embodiment of this application, the fixing sleeve 101 is snapped into the connecting part 202. Further, the connecting part 202 consists of two spaced-apart claws. The fixing sleeve 101 can be snapped between the two claws, thus clamping the fixing sleeve 101 tightly. This facilitates the connection between the connecting part 202 and the fixing sleeve 101 after the patient adjusts the adhesive part 301, ensuring a secure connection between the fixing sleeve 101 and the connecting part 202 and preventing the fixing sleeve 101 with the drainage tube from separating from the connecting part 202, which could allow the drainage tube to move freely. Alternatively, the fixing sleeve 101 can also be provided with an insert, and the connecting part 202 can have a slot that engages with the insert, thereby achieving the snap-fit ​​connection between the fixing sleeve 101 and the connecting part 202. Those skilled in the art will understand that the detachable connection between the fixing sleeve 101 and the connecting part 202 in this application can also take other forms, such as a threaded connection, which will not be elaborated upon here.

[0039] In one embodiment of this application, the inner wall of the fixing sleeve 101 is provided with an elastic part, which can be made of elastic materials such as rubber and silicone. The elastic part can undergo elastic deformation along the radial direction of the fixing sleeve to change the inner diameter of the fixing sleeve 101, so that the fixing sleeve 101 can be fitted onto the outer wall of drainage pipes of different diameters.

[0040] See Figures 1 to 3 In one embodiment of this application, the digestive tract drainage tube fixing device further includes a first elastic sleeve 206. The first elastic sleeve 206 can be simultaneously fitted onto the connecting part 202 and the transverse rod 203, and generate a radially inward elastic force. The friction between the first elastic sleeve 206, the connecting part 202, and the transverse rod 203 can restrict the movement of the connecting part 202 along the transverse rod 203, thereby preventing changes in the transverse distance between the connecting part 202 and the adhesive part 301. When the patient uses it, pushing the connecting part 202 or the transverse rod 203 can change the transverse distance between the connecting part 202 and the adhesive part 301, thereby meeting the need to adjust the position of the adhesive part 301 and avoiding skin damage.

[0041] In one embodiment of this application, the digestive tract drainage tube fixing device further includes a flexible band 207 located outside the first inflection point 205 in the extending direction. That is, the flexible band 207 is located outside the first inflection point 205 in the plane where the first inflection point 205 extends. One end of the flexible band 207 is connected to the connecting part 202, and the other end is provided with a second elastic sleeve 208. The second elastic sleeve 208 is sleeved on the longitudinal rod 204, and can exert a force on the connecting part 202 along the transverse rod 203 towards the adhesive part 301 through the friction between the flexible band 207 and the longitudinal rod 204. This allows the flexible band 207 to limit the increase of the distance between the connecting part 202 and the adhesive part 301. At the same time, the flexible band 207 can conform to the curve at the first inflection point 205, reducing the space occupied by this application.

[0042] In one embodiment of this application, the adhesive part 301 is detachably connected to the frame. When the adhesive part 301 becomes contaminated or the adhesive layer becomes less sticky, a new adhesive part 301 can be replaced. Those skilled in the art will understand that the detachable connection between the adhesive part 301 and the frame in this application can be achieved through a snap-fit ​​mechanism. See [link to relevant documentation]. Figure 3 It can also be connected by studs, which will not be elaborated here.

[0043] In one embodiment of this application, the fixing sleeve 101 is conical, which facilitates the insertion of the fixing sleeve 101 into the nostril and cooperates with the adhesive part 301. The combined effect of the two restricts the movement of the drainage tube.

[0044] Furthermore, in one embodiment of this application, the side wall of the fixing sleeve 101 is provided with a ventilation channel 102, which penetrates the fixing sleeve 101 along the axial direction of the fixing sleeve 101, allowing outside air to enter the nostrils through the ventilation channel 102, and enabling the patient to breathe to a certain extent through the ventilation channel 102.

[0045] In one embodiment of this application, the inner wall of the fixing sleeve 101 is provided with a friction layer to increase the friction between the fixing sleeve 101 and the drainage tube. The friction layer can be made of materials such as rubber, and the surface of the friction layer is uneven to increase the friction between the fixing sleeve 101 and the drainage tube, prevent the drainage tube from moving relative to the fixing sleeve 101, and ensure the restriction effect of this application on the drainage tube.

[0046] It should be understood that although this specification describes various embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
