[0027] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.
[0028] Combination Figures 1 to 5 As shown, the utility model discloses a uniform anesthetic drug pushing device, comprising an anesthetic drug pusher 1, wherein the anesthetic drug pusher 1 comprises a syringe barrel body 1a, a movable rod 1b and a rubber plug 1c, wherein the end of the syringe barrel body 1a with an injection needle is an injection end, and the other end of the syringe barrel body 1a is an open end, wherein the movable rod 1b is pluggably inserted into the interior of the barrel body from the open end, and the rubber plug 1c is installed on the end of the movable rod 1b close to the injection end, and further comprises a stable pushing auxiliary mechanism 2, wherein the stable pushing auxiliary mechanism 2 is detachably arranged at the open end, and the stable pushing auxiliary mechanism 2 is used to limit the plugging and pulling movement of the movable rod 1b inside the barrel body, and the stable control mechanism provides support for the movable rod 1b when it is pushed and pulled, so that the movable rod 1b is more stable when it is pushed and pulled, thereby ensuring the stability and accuracy of the injection, thereby improving the stable effect of uniform injection when the anesthetic drug pusher 1 injects anesthetics. At the same time, the stable push auxiliary mechanism 2 is detachably arranged at the open end. The detachable design enables the stable push auxiliary mechanism 2 to be used independently of the syringe barrel 1a, or to be used in conjunction with different syringe barrels 1a, thereby improving the flexibility and adaptability of the stable push auxiliary mechanism 2. At the same time, it is also convenient to operate the stable push auxiliary mechanism 2, reducing the difficulty of assembling and operating the stable push auxiliary mechanism 2.
[0029] In order to stabilize the insertion and extraction movement of the movable rod 1b in the cylinder body by the push auxiliary mechanism 2, the anesthetic agent pusher 1 can stably and evenly inject the anesthetic agent. Figure 2 and Figure 3 As shown, the stable push auxiliary mechanism 2 includes a fixed shell 2a and a plurality of limit rods 2b, the fixed shell 2a is detachably mounted on the open end of the syringe barrel 1a, all the limit rods 2b are radially arranged in the fixed shell 2a along the insertion and extraction direction of the movable rod 1b in the barrel as the center, and one end of all the limit rods 2b is in contact with the movable rod 1b. Through the contact between all the limit rods 2b and the movable rod 1b, the insertion and extraction movement of the movable rod 1b in the barrel can be limited, thereby improving the stable effect of uniform injection when the anesthetic pusher 1 injects the anesthetic.
[0030] In order to further improve the stability and smoothness of the stable push auxiliary mechanism 2. Specifically, refer to Figure 2 and Figure 3 As shown, the stable push auxiliary mechanism 2 also includes a plurality of balls 2c, the number of which is the same as the number of the limit rods 2b, and all of the balls 2c are rollably arranged on the corresponding limit rods 2b, and are located at the end where the limit rods 2b and the movable rod 1b are in contact. The balls 2c can roll freely on the limit rods 2b, which can effectively reduce the friction and resistance of the movable rod 1b during the push-pull process, making the operation more stable and smooth, thereby improving the stable effect of uniform injection of the anesthetic pusher 1 when injecting the anesthetic. At the same time, the rolling friction of the balls 2c causes less wear on the mechanical structure than the traditional sliding friction, thereby extending the service life of the device.
[0031] Specifically, refer to Figure 2 and Figure 3 As shown, the stable push auxiliary mechanism 2 also includes a plurality of limit holes 2d, the number of the limit holes 2d is the same as the number of the limit rods 2b, all the limit holes 2d are radially arranged on the inner wall of the fixed shell 2a along the insertion and extraction direction of the movable rod 1b in the cylinder as the center of the circle, and all the limit rods 2b are movably arranged in the corresponding limit holes 2d. The matching design of the limit holes 2d and the limit rods 2b can effectively limit the moving position of the movable rod 1b in the cylinder, reduce shaking and deviation, improve the accuracy and stability of injection, and thus improve the stable effect of uniform injection when the anesthetic pusher 1 injects anesthetics. At the same time, by accurately controlling the moving range of the movable rod 1b, the errors that may occur during the operation can be reduced, and the safety of use can be improved. In addition, the design of the limit holes 2d allows the position of the limit rod 2b to be adjusted according to actual needs, with high flexibility and adaptability.
[0032] Specifically, the inner wall of all the limiting holes 2d is provided with an internal thread, and the side wall of all the limiting rods 2b is provided with an external thread screwed with the internal thread of the inner wall of the limiting hole 2d. When the limiting rod 2b is rotated, the position of the limiting rod 2b in the limiting hole 2d can be adjusted by the screwing connection between the external thread and the internal thread. Through the precise matching between the external thread and the internal thread, the high-precision adjustment of the limiting rod 2b can be achieved, thereby improving the accuracy and stability of the injection, and further improving the stable effect of uniform injection when the anesthetic agent pusher 1 injects the anesthetic agent.
[0033] Specifically, refer to Figure 2 and Figure 3As shown, the fixed housing 2a includes a first housing 2a1 and a second housing 2a2, and the first housing 2a1 and the second housing 2a2 are symmetrically and detachably mounted on the open end of the syringe barrel 1a. By designing the fixed housing 2a as a symmetrical detachable structure including the first housing 2a1 and the second housing 2a2, the assembly process is simplified, and the detachability makes it easier to repair and replace parts. In addition, the detachable design enables the fixed housing 2a to adapt to syringe barrels 1a of different diameters or types, thereby improving the versatility of the device.
[0034] Specifically, refer to Figure 2 and Figure 4 As shown, when the movable rod 1b in the anesthetic agent pusher 1 is a cross structure, the number of the limit rods 2b in the fixed shell 2a is 4, and the setting of the 4 limit rods 2b can more comprehensively limit the movement of the movable rod 1b of the cross structure in the cylinder, thereby improving the accuracy and stability of injection. When in use, the 4 limit rods 2b respectively conflict with the four right angles of the movable rod 1b of the cross structure, thereby limiting the movement of the movable rod 1b of the cross structure in the cylinder, thereby improving the accuracy and stability of injection, thereby improving the stable effect of uniform injection when the anesthetic agent pusher 1 injects anesthetic agents.
[0035] Specifically, refer to Figure 3 and Figure 5 As shown, when the movable rod 1b in the anesthetic agent pusher 1 is a cylindrical structure, the number of the limiting rods 2b in the fixed housing 2a is 6. The setting of the 6 limiting rods 2b can more comprehensively limit the movement of the movable rod 1b of the cylindrical structure in the cylinder, improve the accuracy and stability of injection, and when in use, the 6 limiting rods 2b respectively conflict with the side wall of the movable rod 1b of the cylindrical structure from 6 different directions, thereby limiting the movement of the movable rod 1b of the cylindrical structure in the cylinder, improving the accuracy and stability of injection, and thus improving the stable effect of uniform injection when the anesthetic agent pusher 1 injects anesthetic agents.
