Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an adjustable and fixed nursing device for nasogastric tubes used in gastroenterology. Background Technology

[0002] In gastroenterology, nasogastric feeding is a common treatment for patients who cannot eat orally or require special nutritional support. Liquid food, medication, or nutritional solutions are delivered directly into the stomach through a nasogastric tube to meet the patient's nutritional needs and treatment objectives. However, traditional methods of fixing nasogastric tubes have some problems, such as insecure fixation leading to displacement or dislodgement of the tube, and prolonged use may cause skin damage or discomfort, placing additional physical and psychological burdens on patients.

[0003] Utility model patent publication number CN203220598U discloses a nasogastric tube fixing device, including an arc-shaped arm, an ear cover, and an elastic band. Its key feature is a fixing plate located in the middle of the elastic band, with a tube clamp on the fixing plate and forceps attached to the tube clamp. This fixing device has a simple structure, using a combination of the elastic band and the tube clamp to prevent the nasogastric tube from slipping out or in when inserted into the patient. However, it requires adhesive tape for fixing. Since the adhesive tape easily loses its stickiness due to the patient's sweat, skin oil secretion, or daily activities, the nasogastric tube is prone to instability, requiring frequent tape replacements and increasing the workload of medical staff. Therefore, we propose an adjustable fixing and nursing device for nasogastric tubes in gastroenterology to solve the above problems. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, an adjustable and fixed nursing device for nasogastric tubes in gastroenterology is provided.

[0005] The technical implementation scheme of this utility model is as follows: an adjustable and fixed nursing device for nasogastric tubes in gastroenterology, including a frame and a nasal support. The frame is the assembly carrier of this nursing device. The frame consists of vertical supports on the left and right sides and an inverted "V"-shaped support in the middle. The nasal support is provided on the side of the inverted "V"-shaped support of the frame. The frame is worn on the bridge of the nose to assist in fixing the nasogastric tube. It also includes elastic bands, a fixing frame, fixing bands, a felt-like adhesive, and a hook-and-loop adhesive. Elastic bands are installed on the top of the vertical supports on both sides of the frame. The ends of the two elastic bands are connected by adjustment components. The adjustable component is used to flexibly adjust the tightness of the elastic band. The elastic component is used to bind the device to the patient's head so that it can be worn on the face. Two fixing frames are symmetrically installed at the bottom of the frame via a fixing bracket. The fixing frames are U-shaped semi-circular tube frames. The fixing frames are used to bend, guide, and clamp the nasogastric tube. Fixing straps are provided at both ends of the fixing frames. The fixing straps are used to limit the nasogastric tube within the fixing frames. A fleece-like patch is provided on the outer wall of the fixing frame, and a hook-like patch is provided on the inner wall of the fixing strap to attach the fleece-like patch.

[0006] As a preferred embodiment of this utility model, the adjusting component includes a housing, a motor, a take-up roller, and a bearing. The free ends of the two elastic bands are connected to the housing. The housing is made of a lightweight material and has two chambers inside. A motor is fixedly installed in one chamber of the housing, and a take-up roller is rotatably installed in the other chamber via a bearing. The output shaft of the motor passes through the housing and is connected to the take-up roller. Both elastic bands slide through the housing and are connected to the take-up roller. After the motor drives the take-up roller to rotate, the two elastic bands can be wound around the take-up roller. Changing the binding length of the two elastic bands automatically adjusts the binding tightness.

[0007] As a preferred technical solution of this utility model, memory foam is provided on the inner side of the vertical supports on both sides of the frame. The memory foam is used to comfortably fit the contour of the patient's head and improve the comfort of wearing the nursing device for a long time.

[0008] As a preferred technical solution of this utility model, the bottom two sides of the frame are symmetrically provided with sliding grooves, and the fixing frame is slidably assembled in the corresponding sliding groove of the frame through the fixing bracket. Sliding damping is provided between the fixing bracket and the sliding groove of the frame. The position of the fixing frame can be adjusted by sliding within the sliding groove of the frame so that the fixing frame can flexibly fix the nasogastric tube.

[0009] As a preferred technical solution of this utility model, a second memory foam is provided on the side of the outer shell facing the patient's head. The second memory foam is used to disperse the pressure of the shell on the patient's head and reduce the risk of pressure sores caused by prolonged pressure.

[0010] As a preferred embodiment of this utility model, it also includes a cover plate. The cover plate is slidably installed at the opening of the cavity where the motor is located on the outer shell. The cover plate can be slidably opened on the outer shell to facilitate maintenance of the motor installed inside the outer shell.

[0011] The beneficial effects are as follows: 1. This utility model adopts a "U"-shaped semi-circular tube frame design for the fixing frame, which, together with the velvet and hook stickers, can be bent to guide and clamp the nasogastric tube, ensuring that it is firmly fixed on the fixing frame, which facilitates the stable reinforcement of the nasogastric tube. Furthermore, the fixing frame can be slidably adjusted within the fixing bracket to provide a more flexible nasogastric tube fixing solution.

[0012] 2. This utility model uses memory foam one and memory foam two to conform to the contour of the patient's head and disperse the pressure of the shell on the head, effectively improving the comfort of wearing for a long time and reducing the risk of pressure sores.

[0013] 3. This utility model can also flexibly adjust the tightness of the elastic band according to the patient's specific needs through a motor-driven winding roller and adjusting components, ensuring comfortable and secure wearing. Attached Figure Description

Detailed Implementation

[0019] Although this invention may be described with respect to a particular application or industry, those skilled in the art will recognize its broader applicability. Those skilled in the art will understand that terms such as "above," "below," "upward," "downward," etc., are used to describe the drawings and not to indicate a limitation on the scope of the invention as defined by the appended claims. Any numerical designations such as "first" or "second" are merely illustrative and not intended to limit the scope of the invention in any way.

[0020] An adjustable and fixed nursing device for nasogastric tubes in gastroenterology, such as Figures 1-4 As shown, the device includes a frame 1 and a nose pad 2. The frame 1 serves as the mounting carrier for this nursing device. The frame 1 consists of vertical supports on the left and right sides and an inverted "V"-shaped support in the middle. The nose pad 2 is located on the side of the inverted "V"-shaped support of the frame 1. The frame 1 is worn on the bridge of the nose to help fix the nasogastric tube. It also includes an elastic band 3, a fixing frame 5, a fixing strap 7, a felt patch 8, and a hook patch 9. Elastic bands 3 are installed at the top of the vertical supports on both sides of the frame 1. The ends of the two elastic bands 3 are connected by an adjusting component, which is used to flexibly adjust the tightness of the elastic bands 3. The device is secured to the patient's head by the elastic component, allowing it to be worn on the face. The bottom of the frame 1 is secured by a fixing frame. Two fixing frames 5 are symmetrically installed. The fixing frame 5 is a U-shaped semi-circular tube frame. The fixing frame 5 is used to bend, guide and clamp the nasogastric tube. Fixing straps 7 are provided at both ends of the frame of the fixing frame 5. The fixing straps 7 are used to limit the nasogastric tube inside the fixing frame 5. The outer wall of the fixing frame 5 is provided with a fleece 8. The inner wall of the fixing strap 7 is provided with a hook-shaped adhesive 9 to cooperate with the fleece 8. According to the actual use needs, the nasogastric tube is bent and embedded into the fixing frame 5. Then, the hook-shaped adhesive 9 on the fixing strap 7 and the fleece 8 on the fixing frame 5 are glued to each other and the two ends of the nasogastric tube are fixed, so that the nasogastric tube can be stably limited on the fixing frame 5, which facilitates the stable reinforcement of the nasogastric tube used in nursing.

[0021] like Figure 1 and Figure 4 As shown, the adjusting component includes a housing 10, a motor 11, a take-up roller 12, and a bearing 13. The free ends of the two elastic bands 3 are connected to the housing 10. The housing 10 is made of a lightweight material and has two chambers inside. The motor 11 is fixedly installed in one chamber of the housing 10, and the take-up roller 12 is rotatably installed in the other chamber through the bearing 13. The output shaft of the motor 11 passes through the housing 10 and is connected to the take-up roller 12. Both elastic bands 3 slide through the housing 10 and are connected to the take-up roller 12. After the motor 11 drives the take-up roller 12 to rotate, the two elastic bands 3 can be wound around the take-up roller 12. Changing the binding length of the two elastic bands 3 can automatically adjust the binding tightness.

[0022] like Figure 1 and Figure 2 As shown, memory foam 4 is provided on the inner side of the vertical supports on both sides of the frame 1. The memory foam 4 is used to comfortably fit the contour of the patient's head and improve the comfort of wearing the nursing device for a long time.

[0023] like Figure 1 and Figure 2 As shown, the bottom two sides of the frame 1 are symmetrically provided with sliding grooves 6. The fixed frame 5 is slidably assembled in the corresponding sliding groove 6 of the frame 1 through the fixed bracket 51. There is sliding damping between the fixed bracket 51 and the sliding groove 6 of the frame 1. The position of the fixed frame 5 can be adjusted by sliding in the sliding groove 6 of the frame 1 so that the fixed frame 5 can flexibly fix the nasogastric tube.

[0024] like Figure 4 As shown, a memory foam 2 15 is provided on the side of the outer shell 10 facing the patient's head. The memory foam 2 15 is used to disperse the pressure of the shell on the patient's head and reduce the risk of pressure sores caused by prolonged pressure.

[0025] like Figure 4 As shown, it also includes a cover plate 14. The cover plate 14 is slidably installed at the opening of the chamber where the motor 11 is located on the housing 10. The cover plate 14 can be slidably opened on the housing 10 to facilitate maintenance of the motor 11 installed inside the housing 10.

[0026] First, the medical staff places the inverted "V"-shaped nose pad 2 of frame 1 against the patient's nasal bridge. The vertical supports on both sides extend naturally along the facial contour to above the ears. The motor 11 inside the lightweight shell 10 drives the winding roller 12 to automatically contract the elastic bands 3 on both sides, tightening them around the back of the head. At the same time, the memory foam 4 conforms to the patient's head, and the memory foam 15 cushions the pressure of the shell 10, achieving adaptive tightness adjustment and avoiding the risk of pressure sores caused by traditional straps being too tight. Then, the nasogastric tube is led out along the nasal cavity. The "U"-shaped fixing frames 5 on both sides are slid and adjusted according to the tube's direction. The fixing frame 51 is pinched and moved along the bottom groove 6 of frame 1 to the natural curvature of the nasogastric tube (such as the nose). (Outer side of the wing or cheek) After releasing, the sliding damping ensures that the fixed frame 5 is firmly positioned. Then, the nasogastric tube is inserted into the semi-circular guide groove of the fixed frame 5, and the tube is bent in the direction to reduce the tension. Finally, the hook-faced sticker 9 on the inner wall of the fixing band 7 is precisely pressed against the felt-faced sticker 8 on the outer wall of the fixed frame 5 to effectively disperse the risk of displacement of the nasogastric tube. When the patient finds that the elastic band 3 is loose while sliding, the motor 11 is activated again. The motor 11 then adaptively winds the elastic band 3 to keep the elastic band 3 in a continuous state of appropriate pressure. During maintenance, the motor 11 assembly can be inspected simply by sliding the outer shell 10 and the cover plate 14 without disassembling the entire device, thus reducing the maintenance cost of the nursing device.
