Description

Technical Field

[0001] This utility model relates to the field of anesthesia equipment technology, and in particular to an auxiliary fixation device for anesthesia tubing. Background Technology

[0002] Anesthesia is classified into general anesthesia, regional anesthesia, and local anesthesia. General anesthesia includes intravenous anesthesia and inhalation anesthesia. Inhalation anesthesia refers to achieving anesthesia through the inhalation of anesthetic gases. It is characterized by its high controllability and is often used for prolonged surgeries.

[0003] Inhalation anesthesia involves an anesthesia machine and an anesthetic tubing connected to it. The other end of the tubing connects to the patient's trachea. This tubing can be secured to the patient's face via an anesthesia mask, inserted into the trachea via an endotracheal tube, or secured to the trachea via a laryngeal mask. During anesthesia, a gap exists between the anesthesia machine and the patient, typically connected by an anesthetic tubing (e.g., a corrugated tube). However, corrugated tubes can bend, reducing the cross-sectional area of ​​the airway and potentially causing gas supply problems, posing a risk. Furthermore, patient movement during surgery carries the risk of tubing dislodgement. Dislodgement can interrupt the supply of anesthetic gas or oxygen, leading to hypoxia, carbon dioxide buildup, and even death. It can also cause displacement of the endotracheal tube or laryngeal mask within the trachea, damaging the glottis or tracheal mucosa, resulting in single-lung ventilation, impaired gas exchange, or lung damage such as pneumothorax.

[0039] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0040] Reference Figures 1 to 7 As shown in the figure, this utility model embodiment proposes an auxiliary fixation device for anesthesia tubing, including: a main body 100 and a fixation strap 200.

[0041] The main body 100 is a cylindrical shape with an arc. A fixing groove 110 is provided on the side of the main body 100 away from its own center. The fixing groove 110 is also set along the arc direction and is consistent with the arc direction of the main body 100. The two ends of the fixing groove 110 along the arc direction are completely connected to the two ends of the main body 100 along the arc direction, so that the anesthesia tube can be inserted into the fixing groove 110 along the arc direction. In this embodiment, the bottom surface 111 of the groove is semi-circular, that is, the cross section of the bottom surface 111 of the groove perpendicular to the arc direction is a semi-circular arc. The shape of the bottom surface 111 of the groove can also be a minor arc shape, which is an arc with a central angle of less than 180°. The groove opening of the fixing groove 110 is consistent with the two ends of the arc of the bottom surface 111 of the groove, so that the groove opening of the fixing groove 110 is greater than or equal to the size inside the fixing groove 110. For example, the fixing groove 110 has only an arc-shaped bottom surface 111 to fit with the outer peripheral surface of the anesthesia tube, so that the outer peripheral surface of the anesthesia tube is subjected to uniform pressure and local pressure is reduced.

[0042] The central angle of the groove bottom surface 111 along the arc direction is α, and the radius is R. The groove bottom surface 111 satisfies: 90°≤α≤150°, 20cm≤R≤60cm, so that the fixed groove 110 has a certain length along the arc direction. It can guide the anesthesia tube to bend by its own length, and avoid the problem that the length of the fixed groove 110 is too small, which would result in the anesthesia tube having too small a rotation range when passing through the fixed groove 110, and still having the problem of the anesthesia tube having too large a bending angle.

[0043] One end of the fixing strap 200 is connected to the main body 100 and located on one side of the opening of the fixing groove 110. The other end is detachably connected to the main body 100 and located on the other side of the opening of the fixing groove 110. The fixing strap 200 is used to fix the anesthesia tube located within the fixing groove 110. When the other end of the fixing strap 200 is connected to the main body 100, the fixing strap 200 extends across the opening of the fixing groove 110 to fix the anesthesia tube. Since the anesthesia tube is a corrugated tube, each section of the corrugated tube has a groove. The fixing strap 200 can be placed within the groove to fix the corrugated tube without squeezing it, making the fixation of the anesthesia tube more reliable. The opening of the fixing groove 110 is also located on the side of the main body 100 away from the center. When the corrugated tube is bent, the width of the groove that contacts the side of the fixing groove 110 also increases accordingly, making it easier for the fixing strap 200 to be fixed within the groove. In this embodiment, the fixing strap 200 and the main body 100 are detachably connected by a Velcro structure. The Velcro structure is easy to detach and connect, making it convenient for medical staff to use.

[0044] It is worth understanding that the anesthesia tube is placed within the fixing groove 110, and the anesthesia tube bends along the bottom surface 111 of the fixing groove 110. The curvature of the anesthesia tube will be adapted to the curvature of the fixing groove 110, and based on the size of the bottom surface 111, the anesthesia tube will not have a large angle bend, so that the anesthesia tube is less likely to reduce the internal airway cross-section due to bending. The anesthesia tube is fixed in the fixing groove 110 of the main body 100 by the fixing strap 200, so that the main body 100 and the fixing strap 200 can be installed at any bending position of the anesthesia tube to guide the bending of the anesthesia tube. It can be used at any bending position of the anesthesia tube, with a wider range of applications and lower usage requirements. In addition, the other end of the fixing strap 200 is detachably connected to the main body 100, which also facilitates the installation of different anesthesia tubes.

[0045] Reference Figure 1 , Figure 2 and Figure 3 As shown, in some specific embodiments of this utility model, the fixing groove 110 includes a minor arc groove, the inner circumferential surface of which is used to fit the outer circumferential surface of the cylindrical anesthesia tube. The diameter of the minor arc groove can be the same as the diameter of the anesthesia tube, and the opening of the minor arc groove does not affect the placement of the anesthesia tube, making it easier to place the anesthesia tube within the fixing groove 110. Furthermore, the outer circumferential surface of the anesthesia tube can better fit the groove circumferential surface of the fixing groove 110, resulting in better support for the anesthesia tube from the fixing groove 110.

[0046] Reference Figure 3 As shown, in some specific embodiments of this utility model, the main body 100 has a first connecting portion 120 for connection on the side away from the fixing groove 110. When the main body 100 needs to be connected to other objects, it can be connected through the first connecting portion 120, so that the position of the main body 100 is fixed and the use is more reliable. In this embodiment, the first connecting portion 120 can be a magnet, and the first connecting portion 120 can be connected to the iron bracket 300. Alternatively, the first connecting portion 120 can be a negative pressure adsorption component, which can be fixed to a smooth surface by negative pressure, such as a platform for placing an anesthesia machine, or the surface of other equipment near the operating table.

[0047] Reference Figure 4 and Figure 5 As shown, in some specific embodiments of this utility model, it also includes: a bracket 300; the main body 100 is detachably connected to the bracket 300.

[0048] It should be noted that when a patient wears an anesthesia mask, there is a certain gap between the anesthesia machine and the bed. This causes some of the anesthesia tubing to hang down in this gap due to gravity. The hanging part of the anesthesia tubing exerts a certain pulling force on the anesthesia mask, which can easily cause the anesthesia mask to shift under the action of this pulling force, thereby affecting the anesthesia and oxygen delivery effect.

[0049] In this embodiment, the support 300 is mounted on one side of the bed, the main body 100 is installed on the support 300, and anesthesia tubing is installed thereon. The anesthesia tubing will be raised by the support 300 to overcome the influence of gravity, so that the anesthesia tubing will hang down naturally to the patient's face, thereby reducing the pulling force of gravity on the anesthesia tubing and making the use of the anesthesia mask more reliable.

[0050] It is worth understanding that the main body 100 can be detachably connected to the bracket 300, so that the main body 100 can be used alone or connected to the bracket 300 for use, making it more convenient to use.

[0051] Reference Figure 4 and Figure 5 As shown, in some specific embodiments of this utility model, the main body 100 has a first connecting portion 120 for connection on the side away from the fixing groove 110; the bracket 300 includes a first rod portion 310 and a second rod portion 320, the first rod portion 310 is connected to the second rod portion 320 and is set at an angle, and the first rod portion 310 has a second connecting portion 311; wherein, the first connecting portion 120 can be magnetically connected to the second connecting portion 311.

[0052] It is worth understanding that the first connecting part 120 and the second connecting part 311 are magnetically connected and fixed to facilitate disassembly and reassembly between the main body 100 and the bracket 300, making it more convenient for medical personnel to use. In this embodiment, the first rod part 310 is perpendicular to the second rod part 320, and the first rod part 310 is generally arranged in a direction parallel to the bed body, while the second rod part 320 is generally arranged in a direction perpendicular to the bed surface. The first rod part 310 is plate-shaped or cylindrical.

[0053] Reference Figure 4 and Figure 5 As shown, in some specific embodiments of this utility model, the first connecting part 120 includes a column 121 connected to the main body 100 at one end, a connecting groove 122 provided at the other end of the column 121, and a first magnetic member 123 provided in the connecting groove 122; the second connecting part 311 includes a second magnetic member, which can be inserted into the connecting groove 122 and magnetically connected to the first magnetic member 123.

[0054] In this embodiment, the second magnetic component is inserted into the connecting groove 122 and connected to the first magnetic component within the connecting groove 122 to achieve magnetic fixation, thereby making the second magnetic component and the first magnetic component magnetically fixedly connected, which is convenient for medical personnel to use.

[0055] Furthermore, the connecting groove 122 restricts the second magnetic member from rotating along the circumferential direction of the column portion 121. When the connecting groove 122 is non-cylindrical, and the inner circumferential surface shape of the connecting groove 122 matches the inner circumferential surface shape of the second magnetic member, the second magnetic member will have difficulty rotating along the circumferential direction of the connecting groove 122, thereby restricting the relative rotation between the first rod portion 310 and the main body 100. This allows the main body 100 to be fixedly connected to the second magnetic member along the circumferential direction of the column portion 121, preventing the anesthesia tube from being pulled due to the rotation of the main body 100. In this embodiment, the inner circumferential surface of the connecting groove 122 is a rectangular circumferential surface, and the outer circumferential surface of the second magnetic member is also a rectangular circumferential surface. The inner circumferential surface of the connecting groove 122 can also be a circumferential surface of other polygonal shapes, and the outer circumferential surface shape of the second magnetic member matches the shape of the inner circumferential surface of the connecting groove 122. As another embodiment, the connecting groove 122 and the second magnetic member can also restrict rotation through a keyway structure.

[0056] Reference Figure 6 and Figure 7 As shown, in some specific embodiments of this utility model, the support 300 includes a first rod portion 310, a second rod portion 320, and a third connecting portion. The first rod portion 310 is connected to one end of the second rod portion 320 and is set at an angle to the second rod portion 320. The third connecting portion is connected to the other end of the second rod portion 320 and is used to connect to the hospital bed.

[0057] It is worth noting that the stent 300 is connected to the hospital bed via a third connecting part, thus achieving the connection between the stent 300 and the hospital bed. Alternatively, the stent 300 and the hospital bed can be integrated into a single unit.

[0058] In some specific embodiments of this utility model, the third connecting part includes a third rod part 330, which is connected to the other end of the second rod part 320 and is perpendicular to the second rod part 320, and extends along the extending direction of the first rod part 310. The third rod part 330 has a third magnetic attractor on the side opposite to the first rod part 310, and the second rod part 320 has a fourth magnetic attractor on the side facing the third rod part 330. The third magnetic attractor and the fourth magnetic attractor can be magnetically connected to the hospital bed together.

[0059] It should be noted that the hospital bed has a rectangular iron frame underneath to support the bed frame. In this embodiment, the third rod 330 is connected to the bottom surface of the iron frame via a third magnetic connector, and the second rod 320 is connected to the outer side of the iron frame via a fourth magnetic connector, thereby fixing the support 300.

[0060] As another implementation method, refer to Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, in some specific embodiments of this utility model, the third connecting part includes a third rod 330 and a fourth rod 340. The third rod 330 is connected to the other end of the second rod 320 and is perpendicular to the second rod 320. The fourth rod 340 is connected to the end of the third rod 330 away from the second rod 320 and is perpendicular to the third rod 330, extending toward the first rod 310. The side of the third rod 330 opposite to the first rod 310 has a fifth magnetic member 331, and the side of the fourth rod 340 opposite to the second rod 320 has a sixth magnetic member 341. The fifth magnetic member 331 and the sixth magnetic member 341 can be magnetically connected to the hospital bed together.

[0061] In this embodiment, the fourth rod 340 is magnetically connected to the inner side of the iron frame via the sixth magnetic chuck 341, and the third rod 330 is magnetically connected to the bottom surface of the iron frame via the fifth magnetic chuck 331. When the support 300 is subjected to an external force from the center of the bed towards the edge of the bed, the magnetic attraction of the fifth magnetic chuck 331 on the third rod 330 counteracts the influence of the external force, resulting in better fixation of the support 300. When the support 300 is subjected to an external force from the edge of the bed towards the center of gravity of the bed, the magnetic attraction of the sixth magnetic chuck 341 on the fourth rod 340 counteracts the influence of the external force, resulting in more reliable fixation of the support 300.

[0062] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
