Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a device for inserting and fixing a nasal cannula to sedate patients. Background Art

[0002] Traditional external fixation of nasogastric tubes usually involves attaching them to the patient's nose with adhesive tape. This fixation method typically has the following drawbacks: 1. It is unsightly and can easily cause skin damage to the patient. 2. There is a risk of nasogastric tube slippage and displacement. 3. Fixing the head forward tilt after nasogastric tube insertion usually requires assistance from others, or a single person cannot stably control the head forward tilt angle, which can easily lead to insufficient or excessive forward tilt angle, affecting the patient's breathing. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a device for inserting and fixing a nasal cannula in sedated patients, comprising: The nasal cannula fixation base includes a first fixation member placed on the posterior side of the skull and a second fixation member connected to both ends of the first fixation member and conforming to the cheekbone; the central cavity of the annular structure formed by the first fixation member and the second fixation member is a head-accommodating area; The nasal cannula fixation component includes a first locking component and a second locking component respectively disposed on both sides of the center of the outer wall of the second fixation component. One end of the first locking component is fixedly connected to the second fixation component, and the other end passes through the second locking component and is locked in place with the second locking component. The area between the inner wall of the first locking component and the outer wall of the second fixation component is the nasal cannula fixation area. The cranial traction device includes a first traction member detachably connected to two second fixing members, and a tightening band detachably connected to each of the two first traction members with one click. The two tightening bands are adjustablely connected via a tightening member. A mandibular accommodating area is formed between the two first traction members, the two tightening bands, and the tightening member.

[0004] Furthermore, the first fastener is a flat, solid structure made of flexible materials, including medical-grade plastics.

[0005] Furthermore, the second fastener is a hollow tubular structure made of flexible materials, including medical-grade plastics.

[0006] Furthermore, the first locking member and the second locking member are made of flexible materials, including medical plastic or medical silicone. The first locking component is a pipe strip, and the second locking component is an arc-shaped locking ring. The two ends of the locking ring are respectively fixedly connected to the upper and lower end faces of the second fixing component. The inner cavity size of the second locking component matches the outer diameter of the pipe strip. The second locking element has at least two.

[0007] Furthermore, the first traction member is a wide bandage, and a fixing clip is provided at one end of the first traction member that connects with the second fixing member, and a female buckle is provided at one end of the first traction member that connects with the tightening band.

[0008] Furthermore, the second fastener has a cylindrical perforated groove on the side away from the cheek in a direction perpendicular to the radial direction; The fixing clip is a cylindrical structure arranged along the width of the wide bandage, and the middle part of the cylindrical structure is connected to the wide bandage through a connecting platform.

[0009] Furthermore, the size of the cylindrical structure matches the hollowed-out groove, and the cylindrical structure is inserted into the hollowed-out groove and then rotated to connect with the second fixing member.

[0010] Furthermore, the end of the tightening band that connects to the first traction member is provided with a male buckle that is fixedly connected to the female buckle.

[0011] Furthermore, the tightening component is a D-ring buckle.

[0012] Furthermore, the side of the second fastener closest to the cheek is covered with medical cotton or soft silicone.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention provides a nasal cannula insertion and fixation device for sedating patients, which is equipped with a nasal cannula fixation base. The nasal cannula fixation base is sleeved on the head and the gastric tube is fixed to the face by a nasal cannula fixation component. The headband structure does not require adhesion or pulling on the patient's skin, thus improving the patient's comfort.

[0014] 2. The present invention provides a nasal cannula insertion and fixation device for sedating patients, which is further provided with a head traction component detachably connected to the nasal cannula fixation base. The head traction component covers the cheek side and extends to the chin, and is locked by a D-ring. After the nasal cannula fixation base is pre-fixed to the face, the head traction component can be pulled towards the chin to control the forward tilt angle with one hand, which facilitates the initial insertion of the gastric tube. The tightening band in the head traction component can be detached from the two first traction components by a buckle. If the forward tilt angle is too large or the tightening band is too tight, causing discomfort to the patient, the buckle can be pulled out for one-click detachment. The structure is simple and convenient, and greatly ensures the safety of the patient.

[0015] 3. The second fixing component of the nasal cannula insertion and fixation device for sedating patients of the present invention is a hollow tubular structure, and the side near the cheek is covered with medical cotton or soft silicone, which can reduce pressure on the skin to a certain extent and reduce the occurrence of pressure sores.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0020] To keep the drawings concise, only the parts relevant to the invention are shown schematically in each figure, and they do not represent the actual structure of the product. Furthermore, for ease of understanding, in some figures, only one of components with the same structure or function is shown schematically, or only one is labeled. In this document, "one" can mean not only "only one" but also "more than one".

[0021] First Embodiment Please see Figure 1-3 The technical solution for nasal cannula insertion and fixation device for sedated patients provided in this embodiment includes the following: The nasal cannula fixation base 1 includes a first fixation member 11 placed on the posterior side of the skull and a second fixation member 12 connected to both ends of the first fixation member 11 and conforming to the cheekbone; the central cavity of the annular structure formed by the first fixation member 11 and the second fixation member 12 is the head accommodating area. The nasal cannula fixation member 2 includes a first locking member 21 and a second locking member 22 respectively disposed on both sides of the center of the outer wall of the second fixation member. One end of the first locking member 21 is fixedly connected to the second fixation member, and the other end passes through the second locking member 22 and is locked in place with the second locking member 22. The area between the inner wall of the first locking member 21 and the outer wall of the second fixation member is the nasal cannula fixation area. The cranial traction component 3 includes a first traction component 31 detachably connected to two second fixing components 12, and a tightening band 32 detachably connected to each of the two first traction components 31 with one click. The two tightening bands 32 are adjustablely connected through a tightening component 33. A mandibular bone receiving area is formed between the two first traction components 31, the two tightening bands 32 and the tightening component 33.

[0022] In specific implementation, as shown in the appendix Figure 1 As shown in (a), the upper half of the area with black shadow is the first fastener 11, and the lower half is the second fastener 12; as shown in the attached diagram. Figure 1 As shown in (b), the upper half consists of the first traction member 31 on both the left and right sides, and the lower half consists of the tightening belt 32 connected by the tightening member 33.

[0023] Specifically, since the first fixation member 11 is usually located at the back of the head, in order to improve the patient's comfort when lying flat, the first fixation member 11 is designed as a flat solid structure, and the material is a flexible material including medical plastic.

[0024] Specifically, since the second fastener 12 is usually positioned on the cheekbone facing the nose, in order to reduce pressure on the face, the second fastener 12 is designed as a hollow tubular structure 24, and the material is a flexible material including medical plastic.

[0025] Specifically, the first locking member 21 and the second locking member 22 are made of flexible materials including medical plastic or medical silicone. The first locking member 21 is a pipe strip, and the second locking member 22 is a locking ring with an arc-shaped structure. The two ends of the locking ring are respectively fixedly connected to the upper and lower end faces of the second fixing member. The inner cavity size of the second locking member 22 matches the outer diameter of the pipe strip. The second locking element 22 has at least two.

[0026] Specifically, the first traction member 31 is a wide bandage. One end of the first traction member 31 that connects to the second fixing member 12 is provided with a fixing clip, and the other end of the first traction member 31 that connects to the tightening band 32 is provided with a female buckle. In practical implementation, the contact surface with the cheek can be increased by increasing the width of the wide bandage, thereby distributing the pressure on the face.

[0027] Specifically, the second fastener 12 has a columnar hollow groove 13 on the side away from the cheek in a direction perpendicular to the radial direction; The fixing clip is a cylindrical structure 34 arranged along the width direction of the wide bandage, and the middle part of the cylindrical structure 34 is connected to the wide bandage via a connecting platform. Both the cylindrical structure and the connecting platform are made of medical-grade plastic, and the connection between the wide bandage and the connecting platform can be achieved by thermoforming or other methods.

[0028] Specifically, the size of the columnar structure 34 matches the size of the hollowed-out groove 13, and the columnar structure 34 is inserted into the hollowed-out groove 13 and then rotated to connect with the second fixing member 12.

[0029] In specific implementation, the above is only one way in which the wide bandage and the second fixing member 12 can be detachably fixed. Other methods, such as the end of the wide bandage that is connected to the second fixing member 12 directly passing through the second fixing member 12 and being tied by a slip knot, and then untying the slip knot to disassemble after traction, are all within the protection scope of this invention.

[0030] Specifically, the end of the tightening band 32 that connects to the first traction member 31 is provided with a male buckle that is fixedly connected to the female buckle.

[0031] Specifically, the tightening element 33 is a D-ring buckle.

[0032] Specifically, the side of the second fastener 12 closest to the cheek is covered with medical cotton or soft silicone.

[0033] The working principle or process of the nasal cannula insertion and fixation device for sedating patients provided by this invention is as follows: Preliminary assisted gastric tube (nasal cannula) insertion: Slightly loosen the first locking member 21 to arch it and form a nasal cannula fixation area (the subsequent nasal cannula will also pass through the nasal cannula fixation area). Place the nasal cannula fixation base 1 on the head and position the second fixing member 12 below the nose. Install the head traction member 3 on the nasal cannula fixation base 1 and lock it with a D-ring. Pull the head traction member 3 along the jawline to control the tilt of the patient's head at a certain angle to assist in the initial insertion of the gastric tube (tilting the head forward by 30-45 degrees optimizes the anatomical structure, reduces the risk of aspiration into the airway, improves patient comfort and operation success rate, and makes it easier for the nasogastric tube to enter the esophagus). Fixing the gastric tube: After the gastric tube has been inserted to a certain length, avoiding the trachea, flatten the patient's head, remove the head traction device 3, continue inserting the gastric tube to the preset depth, and tighten the first locking device 21 that protrudes from the right side of the second locking device 22 to complete the insertion assistance and fixation of the gastric tube.

[0034] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
