A fixation device for anesthesia

Abstract

This invention relates to the field of medical device technology, specifically to a fixation device for anesthesia, comprising a slider, a circular plate, a mounting rod, and an adjustment assembly. The adjustment assembly includes an adjustment cover, a mounting component, an adjustment rod, a first gear, a second gear, and a limiting component. Rotating the adjustment rod drives the mounting rod to rotate via the engagement of the first and second gears. This rotation of the mounting rod causes the syringe to rotate, adjusting the syringe angle. By using the adjustment rod and the two gears to drive the mounting rod to rotate and adjust the syringe angle, this invention reduces the deviation in syringe position that occurs after initial adjustment in existing technologies, thereby reducing the need for readjustment and improving anesthesia efficiency. After adjusting the syringe angle by rotating the mounting rod, the limiting component restricts the rotation of the adjustment rod, thus limiting the rotation of the mounting rod and keeping the syringe stable, facilitating smooth injection.

Description

Technical Field

[0001] This invention relates to the field of medical device technology, and specifically to a fixation device for anesthesia. Background Technology

[0002] In medical surgery, patients are usually anesthetized before the operation. Anesthesia fixation devices are used to fix the anesthesia syringe to ensure the injection effect and speed. However, traditional anesthesia syringe fixation devices often cannot adjust the angle of the syringe arbitrarily, which makes them less practical.

[0003] In Chinese patent document CN215083216U, a fixing device for an anesthesia syringe used in an operating room is disclosed. When in use, a motor drives a rotating shaft and a second gear to rotate. Under the action of a rack, the first gear drives the guide rod, fixing plate, clamping plate and syringe to rotate around the rotating shaft and fit against the guide rail. This allows the clamping plate to rotate at any angle in conjunction with the syringe.

[0004] However, in the conventional way of using the above-mentioned fixation device, the position of the syringe is first adjusted so that the syringe is close to the injection position, and then the angle of the syringe is adjusted. But when the rod, fixing plate, clamping plate and syringe rotate around the pivot and along the guide rail to adjust the angle, the height and horizontal position of the syringe will also change when it rotates, which will cause the position of the syringe to deviate. The position of the syringe needs to be adjusted again afterward, which affects the efficiency of the anesthesia work. Summary of the Invention

[0005] The purpose of this invention is to provide a fixation device for anesthesia, which solves the problem of existing fixation devices for operating room anesthesia syringes. In conventional use, the syringe position is first adjusted to bring it close to the injection site, and then the syringe angle is adjusted. However, when the rod, fixing plate, clamping plate, and syringe rotate around the pivot point along the guide rail for angle adjustment, the height and horizontal position of the syringe also change, resulting in a deviation in syringe position. This requires subsequent readjustment of the syringe position, affecting the efficiency of anesthesia.

[0006] To achieve the above technical objectives, the present invention adopts the following technical solution: The present invention provides a fixation device for anesthesia, comprising a slider, a circular plate, and a mounting rod. The circular plate is fixedly connected to the slider and is located in front of the slider. The mounting rod is used to mount a syringe.

[0007] It also includes adjustment components,

[0008] The adjustment assembly includes an adjustment cover, a mounting component, an adjustment rod, a first gear, a second gear, and a limiting component. The adjustment cover is fixedly connected to the circular plate and is located on the side of the circular plate away from the slider. The mounting rod is movably connected to the adjustment cover through the mounting component. One end of the adjustment rod extends into the interior of the adjustment cover, and the other end of the adjustment rod is located on the outside of the adjustment rod. The first gear is fixedly connected to the adjustment rod and is located in the adjustment cover. The second gear is fixedly connected to the mounting rod and meshes with the first gear. The limiting component is used to restrict the rotation of the adjustment rod.

[0009] The limiting component includes a bracket, a limiting frame, a connecting component, and a pushing component. The bracket is fixedly connected to the adjusting cover and is located inside the adjusting cover. The limiting frame is inserted above the adjusting cover. The connecting component is used to connect the bracket and the limiting frame. The pushing component is disposed on the bracket.

[0010] The bracket has a top groove located on the side of the bracket near the limiting frame; the limiting frame further includes a first spring and a push-out plate, the first spring being fixedly connected to the bracket and located in the top groove; the push-out plate being fixedly connected to the first spring and located at the end of the first spring away from the bracket.

[0011] The limiting component further includes a friction ring, which is fixedly connected to the limiting frame and located inside the limiting frame.

[0012] The connecting component includes a plug rod and a limiting rod. The plug rod is fixedly connected to the limiting frame and is located on the side of the limiting frame near the top groove. One end of the limiting rod extends into the top groove, and the other end of the limiting rod is located on the outside of the adjusting cover.

[0013] The bracket also has an inner groove located inside the bracket; the pushing component includes a push plate and a second spring, the push plate being fixedly connected to the limiting rod and located in the inner groove; the second spring is installed between the push plate and the bracket.

[0014] The mounting component includes a mounting plate and a connecting ring. The mounting plate is fixedly connected to the adjusting cover and is located inside the adjusting cover. The mounting plate has a mounting groove located on the side of the mounting plate near the mounting rod. The connecting ring is fixedly connected to the mounting rod and cooperates with the mounting groove.

[0015] This invention provides a fixation device for anesthesia, in which a syringe is mounted on a mounting rod. The position of the syringe can be adjusted via a moving mechanism, bringing the syringe closer to the injection site. Rotating the adjusting rod, through the engagement of a first gear and a second gear, drives the mounting rod to rotate. This rotation of the mounting rod causes the syringe to rotate, adjusting its angle for smoother subsequent injection. The adjustment of the syringe angle by the mounting rod and the two gears reduces deviations in syringe position after initial adjustment, as is common in existing technologies, thus minimizing the need for readjustment and improving anesthesia efficiency. After adjusting the syringe angle by rotating the mounting rod, a limiting member restricts the rotation of the adjusting rod, thereby limiting the rotation of the mounting rod and ensuring syringe stability for smoother injection.

Detailed Implementation

[0023] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0024] First embodiment:

[0025] Please see Figures 1 to 3 , Figure 1 This is a schematic diagram of the anesthesia fixation device according to the first embodiment of the present invention. Figure 2 This is a schematic diagram of the connection between the bracket and the adjustment cover according to the first embodiment of the present invention. Figure 3 This is the invention Figure 2 A magnified view of point A.

[0026] This invention provides a fixation device for anesthesia: comprising a slider 100, a circular plate 101, a mounting rod 102, and an adjustment assembly. The adjustment assembly includes an adjustment cover 103, a mounting component, an adjustment rod 104, a first gear 105, a second gear 106, and a limiting component. The limiting component includes a bracket 107, a limiting frame 108, a connecting component, a pushing component, a first spring 110, a push plate 111, and a friction ring 112. The bracket 107 has a top groove 109 and an inner groove 115. The connecting component includes an insertion rod 113 and a limiting rod 114. The pushing component includes a push plate 116 and a second spring 117. The above technical solution addresses the problem in existing operating room anesthesia syringe fixing devices where, conventionally, the syringe position is adjusted first to bring it close to the injection site, and then the syringe angle is adjusted. However, when the syringe, fixing plate, clamping plate, and syringe rotate around the pivot point along the guide rail for angle adjustment, the syringe's height and horizontal position change accordingly, leading to syringe position deviation. This necessitates subsequent readjustment of the syringe position, affecting the efficiency of anesthesia. The above solution not only prevents syringe movement and reduces syringe position deviation during angle adjustment, ensuring smooth injection, but also addresses the issue of fixing and securing syringes of different models.

[0027] In this specific embodiment, the circular plate 101 is fixedly connected to the slider 100 and is located in front of the slider 100. The mounting rod 102 is used to mount the syringe. The slider 100 is mounted behind the circular plate 101. The slider 100 is used to cooperate with the moving mechanism to move the circular plate 101 back and forth. At the same time, the moving mechanism can also adjust the height of the circular plate 101. The specific structure and working principle of the moving mechanism are existing technologies and will not be described in detail here.

[0028] The adjusting cover 103 is fixedly connected to the circular plate 101 and located on the side of the circular plate 101 away from the slider 100. The mounting rod 102 is movably connected to the adjusting cover 103 through the mounting member. One end of the adjusting rod 104 extends into the interior of the adjusting cover 103, and the other end of the adjusting rod 104 is located on the outside of the adjusting rod 104. The first gear 105 is fixedly connected to the adjusting rod 104 and located in the adjusting cover 103. The second gear 106 is fixedly connected to the mounting rod 102 and meshes with the first gear 105. The limiting member is used to restrict the rotation of the adjusting rod 104. The adjusting cover 103 is installed in front of the circular plate 101. One end of the adjusting rod 104 and the mounting rod 102 respectively extends into the interior of the adjusting cover 103 and is movably connected to the adjusting cover 103. The first gear 105 and the second gear 106 are respectively installed on the outer sides of the adjusting rod 104 and the mounting rod 102. The first gear 105 meshes with the second gear 106. The limiting member is used to restrict the rotation of the adjusting rod 104, thereby keeping the mounting rod 102 stable and preventing the rotation of the mounting rod 102 from affecting the angle of the syringe installation.

[0029] Secondly, the bracket 107 is fixedly connected to the adjusting cover 103 and is located inside the adjusting cover 103; the limiting frame 108 is inserted above the adjusting cover 103; the connecting component is used to connect the bracket 107 and the limiting frame 108; the pushing component is disposed on the bracket 107; the top groove 109 is located on the side of the bracket 107 near the limiting frame 108; the first spring 110 is fixedly connected to the bracket 107 and is located in the top groove 109; the push plate 111 is fixedly connected to the first spring 110 and is located at the end of the first spring 110 away from the bracket 107; the friction ring 112 is fixedly connected to the limiting frame 108 and is located inside the limiting frame 108. The bracket 107 is installed on the bottom inner wall of the adjusting cover 103. The bracket 107 is Y-shaped. The limiting frame 108 is inserted into the adjusting cover 103. The limiting frame 108 is concave. The top of the bracket 107 is provided with the top groove 109. The first spring 110 is installed in the top groove 109. The push plate 111 is installed on the upper end of the first spring 110. The cooperation between the first spring 110 and the push plate 111 facilitates the movement of the limiting frame 108 to separate from the bracket 107, thereby releasing the restriction on the adjusting rod 104. The friction ring 112 is installed on the inner side of the limiting frame 108. The friction ring 112 is used to increase the friction between the limiting frame 108 and the adjusting rod 104, thereby better restricting the rotation of the adjusting rod 104.

[0030] Meanwhile, the insertion rod 113 is fixedly connected to the limiting frame 108 and is located on the side of the limiting frame 108 near the top groove 109; one end of the limiting rod 114 extends into the top groove 109; the other end of the limiting rod 114 is located outside the adjusting cover 103; the inner groove 115 is located inside the bracket 107; the push plate 116 is fixedly connected to the limiting rod 114 and is located in the inner groove 115; the second spring 117 is installed between the push plate 116 and the bracket 107. The lower end of the limiting frame 108 is equipped with the insertion rod 113. One end of the limiting rod 114 extends into the top groove 109, and the other end is located outside the adjusting cover 103. The bracket 107 also has an inner groove 115. The push plate 116 is in abutting connection with the limiting rod 114 and is located in the inner groove 115. The second spring 117 is sleeved on the outside of the limiting rod 114 and is located between the push plate 116 and the bracket 107.

[0031] When using the anesthesia fixation device of this embodiment, the syringe is mounted on the mounting rod 102. The position of the syringe can be adjusted by the moving mechanism to bring the syringe closer to the injection position. Rotating the adjusting rod 104 drives the mounting rod 102 to rotate via the engagement of the first gear 105 and the second gear 106. The rotation of the mounting rod 102 causes the syringe to rotate, adjusting the angle of the syringe to facilitate subsequent injection. The adjustment of the syringe angle by the adjusting rod 104 and the two gears reduces the deviation in syringe position after adjustment in the prior art, thereby reducing the need for readjustment and improving anesthesia efficiency. After adjusting the syringe angle by rotating the mounting rod 102, pressing the limiting frame 108 moves the limiting frame 108, causing the insertion rod 113 to move and insert into the top groove 109. During insertion into the top groove 109, the insertion rod 113 squeezes... The limiting rod 114 is pressed to move, and the movement of the limiting rod 114 drives the push plate 116 to move and compress the second spring 117. When the limiting hole on the insertion rod 113 aligns with the limiting rod 114, the second spring 117 deforms and pushes the limiting rod 114 to move and insert into the insertion rod 113, thereby stably connecting the limiting frame 108 and the bracket 107 together. At this time, the friction ring 112 contacts the surface of the adjusting rod 104, restricting the rotation of the adjusting rod 104, thereby restricting the installation. Rotating the rod 102 stabilizes the syringe, facilitating smooth injection. When the adjusting rod 104 needs to be rotated again, pulling the end of the limiting rod 114 located outside the adjusting cover 103 moves the limiting rod 114 away from the insertion rod 113. At this time, the first spring 110 and the ejector plate 111 cooperate to push the insertion rod 113 out of the top groove 109, causing the limiting frame 108 to separate from the support 107. Then, rotating the adjusting rod 104 adjusts the angle of the syringe.

The mounting groove 219 is cross-shaped, and the connecting ring 220 is installed on the outer side of the mounting rod 102, cooperating with the mounting groove 219.

[0036] When using an anesthesia fixation device according to this embodiment, when the adjusting rod 104 drives the mounting rod 102 to rotate through the cooperation of the first gear 105 and the second gear 106, the mounting rod 102 rotates on the mounting plate 218 through the connecting ring 220, thereby adjusting the angle of the syringe.
