Description

Technical Field

[0001] The utility model relates to the field of anesthesiology, and in particular to an auxiliary injection device for anesthesiology. Background Art

[0002] Anesthesiology is a specialty in the field of medicine that focuses on the study and application of various anesthetic techniques to ensure that patients do not feel pain during surgery or other medical procedures and maintain a safe and stable physiological state. Anesthesiologists are usually called anesthesiologists or anesthesiologists. They are responsible for assessing the patient's health status, selecting appropriate anesthesia methods, monitoring the patient's physiological parameters, and managing complications during anesthesia.

[0003] When performing local anesthesia on a patient, since the anesthetic is not injected into the vein, it is difficult to inject the anesthetic into the body. Doctors often need to use a lot of force to inject the anesthetic, making the injection of the anesthetic time-consuming and laborious.

[0004] Furthermore, in the prior art, when injecting anesthetics, the amount of an injection is determined by the operator based on experience, so that the amount of medicine injected each time is inconsistent. If the incision is long and the tissue to be operated on is deep, it is easy for the amount of medicine injected each time to be inconsistent, and the amount of medicine injected before and after is uneven, which affects the anesthetic effect and is not conducive to the operation. Therefore, we have made improvements on this and proposed an auxiliary injection device for anesthesia. Summary of the invention

[0005] In view of the deficiencies of the prior art, the utility model provides an auxiliary injection device for anesthesia department, which solves the problems mentioned in the background technology.

[0006] In order to achieve the above-mentioned utility model purpose, the utility model provides the following technical solutions:

[0007] The anesthesiology department uses auxiliary injection devices to solve the above problems.

[0008] The specific application is as follows:

[0009] It comprises an injection syringe, a piston is arranged inside the injection syringe, a connecting rod is connected to the surface of the piston, and a connecting piece is connected to the other end of the connecting rod, a fixing box is fixedly installed on the upper surface of the injection syringe, and an automatic injection mechanism is arranged inside the fixing box, and a limiting mechanism is arranged on one side of the connecting rod;

A plurality of connecting grooves are opened on one side surface of the connecting rod, and the first gear is connected to the connecting grooves by meshing connection. The connection between the connecting rod and the fixed box is a sliding connection.

[0015] As a preferred technical solution of the present application, scale lines are provided on the outer surface of the connecting rod.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] In the scheme of this application:

[0018] 1. Through the use of the automatic injection mechanism, when the doctor needs to inject anesthetics into the patient, he can press the switch button on the surface of the fixed box to control the drive motor. The drive motor will drive the third gear at the output end to rotate, and drive the second gear and the internal rotating shaft to rotate. When the rotating shaft drives the first gear on the surface to rotate, it can be engaged with the connecting groove through the first gear, and can drive the connecting rod and the piston at one end to slide inside the injection syringe, so as to automatically inject the anesthetic at a uniform speed, avoiding the need to use a lot of force to inject the anesthetic, which makes the injection of the anesthetic time-consuming and laborious.

[0019] 2. Through the use of the limiting mechanism, when it is necessary to perform quantitative injection of the injected anesthetic, the stopper can be rotated to slide on the surface of the threaded rod. The position of the stopper can be adjusted according to the scale lines on the surface of the connecting rod and the amount required to be injected. When the connecting rod moves downward for injection, after a certain amount has been injected, the stopper will be blocked on the fixed box to achieve the purpose of quantitative injection, avoiding the situation of uneven injection amount, affecting the anesthesia effect, and hindering the operation.

[0032] Combination Figure 1 - Figure 4 As shown, the utility model provides an auxiliary injection device for anesthesia, including an injection syringe 1, a piston 2 is arranged inside the injection syringe 1, and a connecting rod 3 is connected to the surface of the piston 2, and a connecting piece 4 is connected to the other end of the connecting rod 3, a fixed box 5 is fixedly installed on the upper surface of the injection syringe 1, and an automatic injection mechanism 6 is arranged inside the fixed box 5, a limiting mechanism 7 is arranged on one side of the connecting rod 3, the automatic injection mechanism 6 includes a rotating shaft 601, and a first gear 602 is fixedly installed on the outer surface of the rotating shaft 601, a plurality of connecting grooves 603 are opened on one side surface of the connecting rod 3, and the first gear 602 and the connecting groove 603 are connected in a meshing connection manner, and the connection manner between the connecting rod 3 and the fixed box 5 is a sliding connection.

[0033] In this embodiment: when the anesthetic inside the injection syringe 1 needs to be injected, the rotating shaft 601 can be rotated to drive the first gear 602 on the surface to rotate, and the first gear 602 can be engaged with the connecting groove 603 on the surface of the connecting rod 3. The first gear 602 can be rotated to drive the connecting rod 3 to slide in the injection syringe 1 and the fixed box 5, and the piston 2 can be driven by the connecting rod 3 to move in the injection syringe 1 to inject the anesthetic.

[0034] like Figure 1 - Figure 3 As shown, based on the above embodiment, in order to enable the auxiliary injection device for anesthesia department to automatically inject anesthetics, this embodiment provides the following design:

[0035] As a preferred embodiment, the rotating shaft 601 is rotatably connected inside the fixed box 5 , and a second gear 606 is fixedly installed on one side of the first gear 602 and located on the outer surface of the rotating shaft 601 .

[0036] In this embodiment, the second gear 606 can be rotated to drive the rotating shaft 601 to rotate, and at the same time drive the first gear 602 to rotate, thereby achieving the purpose of driving the connecting rod 3 and the piston 2 to move and perform injection.

[0037] As a preferred embodiment, a driving motor 604 is fixedly mounted on the inner wall surface of one side of the fixed box 5, and a third gear 605 is fixedly connected to the output end of the driving motor 604, and the third gear 605 is connected to the second gear 606 in a meshing connection.

[0038] In this embodiment: the driving motor 604 can be started to drive the third gear 605 at the output end to rotate. Since the third gear 605 is meshed with the second gear 606, the second gear 606 and the internal rotating shaft 601 can be driven to rotate, and the first gear 602 on the surface can be driven to rotate, thereby achieving uniform speed injection and avoiding the need to use a lot of force to inject the anesthetic, which makes the injection of the anesthetic time-consuming and laborious.

[0039] As a preferred embodiment, a switch button 607 is fixedly mounted on one side surface of the exterior of the fixed box 5 , and the switch button 607 is connected to the driving motor 604 via a wire.

[0040] In this embodiment: the switch button 607 can be pressed to control the drive motor 604 , and the forward and reverse rotation of the drive motor 604 can be used to realize the drug extraction and injection of the syringe.

[0041] like Figure 1 - Figure 4 As shown, based on the first embodiment, in order to enable the auxiliary injection device for anesthesia to achieve quantitative injection, this embodiment provides the following design:

[0042] As a preferred embodiment, the limiting mechanism 7 includes a threaded rod 701, and the threaded rod 701 is fixedly installed on the lower surface of the connecting plate 4, and the threaded rod 701 is connected to the fixed box 5 in a sliding manner, and the outer surface of the threaded rod 701 is threadedly connected with a stopper 702.

[0043] In this embodiment: the stopper 702 on the surface of the threaded rod 701 is rotated. Since the stopper 702 is threadedly connected to the threaded rod 701, the position of the stopper 702 on the surface of the threaded rod 701 can be adjusted by rotating the stopper 702. When injecting, the connecting rod 3 and the connecting piece 4 will move downward and drive the threaded rod 701 on the surface to move downward. After a certain amount of injection, the stopper 702 on the surface of the threaded rod 701 will block the upper side of the fixed box 5, thereby achieving the purpose of quantitative injection.

[0044] As a preferred embodiment, the outer surface of the connecting rod 3 is provided with scale lines 703 .

[0045] In this embodiment, the position of the stopper 702 and the injection amount can be adjusted by adjusting the scale line 703 on the outside of the connecting rod 3 .

[0046] Specifically, the working principle of this solution is:

[0047] During use, when the doctor needs to inject anesthetics into the patient, he can press the switch button 607 on the surface of the fixed box 5 to control the drive motor 604. The drive motor 604 will drive the third gear 605 at the output end to rotate, and drive the second gear 606 and the internal rotating shaft 601 to rotate. When the rotating shaft 601 drives the first gear 602 on the surface to rotate, it can be engaged with the connecting groove 603 through the first gear 602, and can drive the connecting rod 3 and the piston 2 at one end to slide inside the injection syringe 1, so as to automatically inject the anesthetic at a uniform speed.

[0048] When it is necessary to perform quantitative injection of the injected anesthetic, the stopper 702 can be rotated to slide on the surface of the threaded rod 701. The position of the stopper 702 can be adjusted according to the scale line 703 on the surface of the connecting rod 3 and the amount required to be injected. When the connecting rod 3 moves downward for injection, after a certain amount of injection, the stopper 702 will be blocked on the fixed box 5, so as to achieve the purpose of quantitative injection and avoid the situation of uneven injection amount, which affects the anesthetic effect and is not conducive to the operation.
