Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a medical adjustable oxygen inhalation bracket. Background Art

[0002] An oxygen inhaler is a medical device specifically designed to accurately measure the oxygen flow rate, aiming to provide appropriate oxygen support at a proper flow rate for emergency patients, and is also applicable to hypoxic patients who need oxygen supplementation. According to different usage scenarios, it can be divided into two types: an inhaler for oxygen cylinders and a wall-mounted inhaler. The main difference between the two is that the wall-mounted inhaler can work without an additional pressure reducing valve, and the working principle of both is to use a flow control valve to adjust the oxygen flow rate and intuitively display the flow rate through the float in the built-in flow meter. This makes the oxygen inhaler one of the most commonly used oxygen supply devices in hospitals and has been widely recognized for its mature technology and reliable quality.

[0003] However, some challenges may be encountered when using a wall-mounted oxygen inhaler. Usually, installing a wall-mounted oxygen inhaler requires connecting it to the oxygen interface on the wall. Since the interface is directly connected to the inhaler, the relative position between the two is likely to shift due to movement or pulling. In addition, when a long oxygen pipeline is connected, if the pipeline droops or is accidentally pulled by the caregiver or patient during activities, it may cause the inhaler to tip over, thereby affecting the stability and safety of oxygen supply. Therefore, in view of the above problems, it is necessary to propose a medical adjustable oxygen inhalation bracket that can optimize the management of oxygen pipelines, reduce the risk of the oxygen inhaler tipping over caused by accidental pulling, and thus improve the safety and stability of oxygen supply.

When the moving frame flips upward with the extension rod, the T-shaped frame moves downward and inverted due to gravity, so that the arc plates are snapped together to form a frame for snapping and fixing the oxygen pipeline of the oxygen inhaler.

[0013] As a further preferred solution, plug rods are slidably provided on both sides of the mounting plate, and two elastic members are provided between the plug rods on both sides and the mounting plate.

Detailed implementation manners

[0030] The following will further illustrate the present invention in conjunction with specific embodiments. It should also be noted that unless otherwise clearly defined and limited, terms such as: setting, installation, connection, and coupling should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0031] Embodiment: A medical adjustable oxygen inhalation bracket, as Figures 1 - 7 and Figure 9 shown, includes:

[0032] Mounting plate 1, which is the main part of the bracket and serves as the main mounting carrier for fixing the bracket on the wall surface of the oxygen terminal 100;

[0033] The assembly shaft 2 rotates between the lower positions on the left and right sides of the mounting plate 1. On the assembly shaft 2, extension rods 21 are fixedly arranged at intervals left and right. In the initial state, the two extension rods 21 are longitudinally placed downward, and positioning holes 211 are arranged in a row on both of the two extension rods 21. A movable frame 22 is slidably arranged between the two extension rods 21. The movable frame 22 is a frame with an open upper end and a closed bottom end. By adopting the sliding connection mode between the extension rod 21 and the movable frame 22, the position adjustment of the two is more convenient and flexible to adapt to the use requirements of oxygen inhalers 101 of various sizes. A fastening assembly 5 is arranged at the bottom of the movable frame 22 to limit the position of the oxygen pipeline of the oxygen inhaler 101. Fixed parts that are inserted and matched with the positioning holes 211 on the same side are fixedly arranged on the left and right sides of the movable frame 22 to fix the moving position of the movable frame 22, ensure the position is stable and avoid unnecessary displacement. Guide wheels 23 with arc-shaped grooves 231 are also fixedly arranged on the left and right sides of the assembly shaft 2. The arc-shaped grooves 231 are all located at the upper rear side positions of the corresponding guide wheels 23, and the included angle between the opening of the arc-shaped groove 231 and the center of the corresponding guide wheel 23 is 90 degrees;

[0034] There are two clamping frames 3. The clamping frames 3 slide symmetrically left and right at the middle position of the mounting plate 1. The clamping frames 3 have clamping ends that can fit and clamp the insertion end of the oxygen inhaler 101. The clamping ends are in the shape of triangular plates and can closely fit the concave and convex shapes of the insertion end of the oxygen inhaler 101, thus forming a fitting clamping and fixing, effectively stabilizing the middle two sides of the oxygen inhaler 101, making the connection between the insertion end part and the interface part of the oxygen terminal 100 more firm, and reducing the risk of overall tipping and displacement. Magnets 31 that are magnetically matched with the mounting plate 1 are also arranged at the ends of the clamping frames 3 away from each other to fix the position of the clamping frames 3 in the future and further stabilize the position limitation of the clamping frames 3 on the oxygen inhaler 101;

[0035] A limiting component 4 for limiting the upper position of the oxygen inhaler 101. The limiting component 4 includes a rotating shaft 41 that rotates between the upper positions on the left and right sides of the mounting plate 1. Symmetrically arranged left and right on the rotating shaft 41 are winding wheels 42. The position layout of the winding wheels 42 is adapted to that of the guide wheels 23. A pull rope 44 is connected to the winding wheel 42. The end of the pull rope 44 is connected to the upper rear side position of the winding wheel 42 and is adapted to the position layout of the arc-shaped groove 231. The ends of the two pull ropes 44 are both slidably embedded in the arc-shaped groove 231 on the same side. A torsion spring 43 is arranged between the winding wheel 42 and the side wall of the mounting plate 1. Standing plates are also symmetrically arranged left and right on the rotating shaft 41. A bidirectional lead screw 45 is rotatably arranged between the two standing plates. Symmetrically arranged left and right on the bidirectional lead screw 45 are positioning plates 46. The two positioning plates 46 respectively correspond to one side thread of the bidirectional lead screw 45. Rotating the bidirectional lead screw 45 can adjust the distance between the two positioning plates 46 to be suitable for the insertion of oxygen inhalers 101 of various sizes.

[0036] When the assembly shaft 2 rotates, it will drive the connected rotating shaft 41 to rotate synchronously through the pulling rope 44. Under the limitation of the arc-shaped groove 231, when the extension rod 21 and the moving frame 22 are turned upwards by 180 degrees, the pulling rope 44 is pulled, and the rotating shaft 41 and its upper components are synchronously pulled to turn downwards by 90 degrees. This action can adjust the relative position between the positioning plate 46 and the oxygen inhaler 101, and move the fastening assembly 5 upwards to facilitate the position management of the oxygen pipeline. In this way, the clamping frame 3, the positioning plate 46, and the fastening assembly 5 form a cooperative fixing structure, effectively ensuring the stability of the position of the oxygen inhaler 101 and ensuring the subsequent treatment effect.

[0037] As Figures 2 - 4 shown, the fixing member includes mounting frames 221 fixedly arranged on the left and right sides of the moving frame 22. A clamping ball 222 is slidably inserted through the mounting frame 221. The clamping ball 222 operates in the left-right direction. An elastic member 223 is arranged between the clamping ball 222 and the corresponding mounting frame 221. In this embodiment, the elastic member 223 is a spring, which provides necessary elastic support for the movement of the clamping ball 222. The clamping ball 222 slidably passes through the side wall of the moving frame 22 and is inserted and matched with the same-side positioning hole 211 to cooperatively fix the position between the moving frame 22 and the extension rod 21.

[0038] As Figure 1 、 Figure 2 、 Figure 7 and Figure 9As shown, the fastening assembly 5 includes coupling shafts 51 that rotate symmetrically left and right at the left and right sides of the bottom of the moving frame 22. The two coupling shafts 51 are arranged at intervals. Arc-shaped plates 52 are fixedly provided at the front and rear ends of the coupling shafts 51. In the initial state, the arc-shaped plates 52 as a whole tend downward, and the arc-shaped plates 52 on both sides are in an open state. Connecting plates 53 are fixedly provided at the upper ends of the arc-shaped plates 52. The two connecting plates 53 are in a horizontal and level state. Longitudinal slots extending left and right are also provided on the connecting plates 53. A straight rod is slidably and rotatably arranged between the ends of the two connecting plates 53. A T-shaped frame 54 is slidably penetrated through the middle of the bottom of the moving frame 22 and the two are in abutting cooperation. The top end of the T-shaped frame 54 is connected to the straight rod. The T-shaped frame 54 slides in the up and down direction. When the moving frame 22 rotates upward along with the extension rod 21, the T-shaped frame 54 moves downward to an inverted state due to the action of gravity, thereby synchronously driving the straight rod, the connecting plate 53, and the coupling shaft 51. This action enables the straight rod to drive the connecting plate 53 and the coupling shaft 51 to tilt and rotate, causing the two connecting plates 53 to form a V shape, and at the same time prompting the arc-shaped plates 52 to close; when the T-shaped frame 54 contacts and abuts against the moving frame 22, the movement of the relevant components will stop synchronously, ensuring that the arc-shaped plates 52 are completely closed into a ring structure for fixing the oxygen pipeline of the oxygen inhaler 101, so as to reduce the influencing factors that cause the oxygen inhaler 101 to tip over and further ensure the overall position stability.

[0039] As Figure 2 and Figure 3 shown, insertion rods 24 are slidably arranged on the left and right sides of the mounting plate 1. The insertion rods 24 slide in the up and down direction. Elastic members II 25 are arranged between the two insertion rods 24 and the mounting plate 1. In this embodiment, the elastic members II 25 are springs. The insertion rods 24 are inserted and matched with the same-side end portions of the assembly shafts 2 to limit the positions of the assembly shafts 2 and the components thereon.

[0040] As Figure 6 shown, limiting plates 47 are fixedly provided on the sides of the two vertical plates away from each other. Circular holes with grooves circumferentially arranged on the inner walls are provided in the middle of the limiting plates 47. Clamping plates 48 that are slidable at the left and right ends of the bidirectional lead screw 45 are inserted and matched with the same-side limiting plates 47. Elastic members III 49 are arranged between the clamping plates 48 and the end portions of the bidirectional lead screw 45. In this embodiment, the elastic members III 49 are springs; through the cooperation of the above-mentioned components, the position of the bidirectional lead screw 45 after displacement can be stabilized, ensuring the stability of the structure.

[0041] As Figure 8As shown, a set of sockets 63 arranged at intervals left and right are provided on both the upper and lower side walls of the oxygen terminal 100. A set of guide frames 6 are provided at the upper and lower positions on the rear side of the mounting plate 1. The two guide frames 6 in each group are also arranged at intervals left and right, and the distance between them is greater than the length formed by the connection of the two sockets 63 on the same side. A push frame 61 is slidably arranged in each guide frame 6. The push frame 61 is inserted and matched with the socket 63 at the corresponding position on the same side. An elastic member four 62 is arranged between the push frame 61 and the corresponding guide frame 6. In this embodiment, the elastic member four 62 is a spring, which provides necessary elastic support for the movement of the push frame 61. Through the cooperation of the above components, the detachable installation between the whole bracket and the oxygen terminal 100 can be achieved, and the quick installation and fixation of the bracket can be realized.

[0042] During use, first attach the mounting plate 1 part of the bracket to the front wall of the oxygen terminal 100. By pulling the push frame 61, it slides in the corresponding guide frame 6, and the elastic member four 62 deforms accordingly. After the socket 63 and the guide frame 6 are aligned, then release the push frame 61. Under the action of the reset of the elastic member four 62, the push frame 61 is driven to insert into the corresponding socket 63, thereby fixing the position of the whole bracket on the wall surface of the oxygen terminal 100. Then insert the oxygen inhaler 101 into the interface of the oxygen terminal 100. Then slide and adjust the movable frame 22 to adjust the interval between its bottom and the extension rod 21 to ensure that the interval space is large enough to straddle the oxygen inhaler 101. During this process, as the movable frame 22 slides, the clamping ball 222 will move synchronously with the movable frame 22, continuously switching and moving between the positioning hole 211 and the wall surface of the extension rod 21, and the elastic member one 223 deforms accordingly. Until the movable frame 22 stops operating, the clamping ball 222 stops synchronously and inserts into the corresponding positioning hole 211, thereby stabilizing the position between the movable frame 22 and the extension rod 21. Then toggle the clamping plate 48 to make it slide away from the limiting plate 47 at the end of the bidirectional lead screw 45. The elastic member three 49 deforms accordingly, so that the limiting plate 47 releases the restriction on the bidirectional lead screw 45. Then rotate the bidirectional lead screw 45 to adjust the position spacing between the two positioning plates 46 on it. After that, release the clamping plate 48, and the elastic member three 49 resets, and the clamping plate 48 re-inserts into the limiting plate 47 to stabilize the position of the bidirectional lead screw 45. After all the adjustments are ready, the subsequent limiting operation can be started;

[0043] Ensure that the oxygen inhaler 101 is in a proper position, and then push the clamping frames 3 on both sides towards the insertion end of the oxygen inhaler 101 until the clamping frames 3 on both sides hold the insertion end of the oxygen inhaler 101. The magnet 31 synchronously stabilizes the position between the displaced clamping frame 3 and the mounting plate 1, thereby ensuring the stable position of the oxygen inhaler 101. Then, pull up the insertion rod 24 to make it slide upward on the mounting plate 1, and the second elastic member 25 deforms accordingly to release the restriction of the insertion rod 24 on the assembly shaft 2. Subsequently, hold the bottom of the moving frame 22 and push it to turn upward together with the extension rod 21, and the connected assembly shaft 2 rotates synchronously, causing the guide wheels 23 on both sides of the assembly shaft 2 to also rotate. During this process, when the assembly shaft 2 rotates upward by 90 degrees, the end of the pull rope 44 connected to the guide wheel 23 slides along the corresponding arc-shaped groove 231 along with the movement until the end of the pull rope 44 moves to the other end of the arc-shaped groove 231. After the assembly shaft 2 rotates upward by another 90 degrees, under the synchronous drive of the guide wheel 23, the pull rope 44 is pulled downward, thereby pulling the connected winding wheel 42 and the rotating shaft 41 to rotate downward, and the torsion spring 43 deforms accordingly, and the rotating shaft 41 and its components thereon are turned downward together. The positioning plates 46 on both sides then fit against the sides of the oxygen inhaler 101, thereby synchronously cooperating with the clamping frames 3 to limit the positions of both sides of the oxygen inhaler 101 and ensure the overall position is stable to avoid unnecessary tipping. After that, when the moving frame 22 rotates 180 degrees completely, the bottom end of the moving frame 22 crosses the oxygen inhaler 101 and moves to the upper position, and the extension rod 21 rotates and directly fits against the front wall of the mounting plate 1. Release the insertion rod 24, and the second elastic member 25 resets, and the insertion rod 24 re-inserts into the end of the assembly shaft 2 to fix the overall rotation position. Here, under the influence of gravity, the T-shaped frame 54 slides down after the moving frame 22 flips, thereby pushing the connected connecting plates 53 on both sides to move downward and rotate obliquely, and the connecting shaft 51 rotates synchronously, and then pulls the connected arc-shaped plate 52 to rotate and finally close to form an annular structure for placing the oxygen pipeline of the oxygen inhaler 101. Then, insert the oxygen pipeline into the space between the arc-shaped plate 52 and the moving frame 22, thereby effectively managing the placement of the oxygen pipeline and ensuring the overall position is stable.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit the protection scope of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the essence and scope of the technical solutions of the present invention.
