Description
技术领域Technical Field
本实用新型涉及麻醉定位技术领域，具体提供一种麻醉注射用辅助定位器。The utility model relates to the technical field of anesthesia positioning, and specifically provides an auxiliary positioning device for anesthesia injection.
背景技术Background Art
麻醉方式有三种：1、局部浸润麻醉，局麻的药物需要注射到皮下，注射时进针角度一般与皮肤呈30-40度角，一般不宜超过45度，以免刺入肌层。一般麻醉的范围越大，患者注射时的疼痛越强烈，这种情况下局麻比打针疼痛更加明显。2、腰硬联合麻醉，需要将麻药注射到机体的椎管内,注射时进针角度一般与皮肤呈90度角。患者在麻醉时需要将穿刺针穿过皮肤，皮下组织及椎体间的韧带，患者的疼痛程度比打针也要明显的剧烈。3、静脉麻醉，静脉麻醉是通过静脉给药途径，使患者达到全身麻醉的状态。这种情况下患者往往没有明显疼痛症状，与打针相比全身麻醉疼痛较轻。There are three types of anesthesia: 1. Local infiltration anesthesia. The local anesthetic needs to be injected subcutaneously. The angle of the needle during injection is generally 30-40 degrees to the skin, and generally should not exceed 45 degrees to avoid piercing the muscle layer. Generally, the larger the range of anesthesia, the more intense the pain of the patient during injection. In this case, local anesthesia is more painful than injection. 2. Combined spinal-epidural anesthesia. The anesthetic needs to be injected into the body's spinal canal. The angle of the needle during injection is generally 90 degrees to the skin. During anesthesia, the patient needs to pass the puncture needle through the skin, subcutaneous tissue and ligaments between vertebrae. The patient's pain is also significantly more severe than that of an injection. 3. Intravenous anesthesia. Intravenous anesthesia is administered intravenously to enable the patient to achieve a state of general anesthesia. In this case, the patient often has no obvious pain symptoms, and the pain of general anesthesia is lighter than that of an injection.
为防止进针时患者因疼痛的抖动造成注射器与皮肤的相对移动，同时又应对部分经验不足的医师，在麻醉注射时可用定位器进行辅助。现有的辅助定位器一般只能对注射器的进针深度进行定位，而进针角度关乎患者的疼痛感，甚至安全性，经验不足的医师易因进针角度的疏忽而加剧患者的疼痛感，所以需要一种刻度注射器进针角度进行定位的辅助装置来解决这一问题。In order to prevent the relative movement of the syringe and the skin caused by the patient's shaking due to pain during the injection, and to deal with some inexperienced doctors, a positioner can be used to assist in anesthesia injection. Existing auxiliary positioners can generally only locate the injection depth of the syringe, while the insertion angle is related to the patient's pain and even safety. Inexperienced doctors are prone to aggravate the patient's pain due to negligence of the insertion angle, so an auxiliary device for calibrating the syringe insertion angle for positioning is needed to solve this problem.
实用新型内容Utility Model Content
(一)解决的技术问题1. Technical issues to be solved
针对现有技术的不足，本实用新型提供了一种麻醉注射用辅助定位器，解决了现有的辅助定位器一般只能对注射器的进针深度进行定位，而进针角度关乎患者的疼痛感，经验不足的医师易因进针角度的疏忽而加剧患者的疼痛感问题。In view of the deficiencies in the prior art, the utility model provides an auxiliary positioner for anesthesia injection, which solves the problem that the prior auxiliary positioners can generally only position the needle insertion depth of the syringe, while the needle insertion angle is related to the patient's pain. Inexperienced doctors may easily aggravate the patient's pain due to negligence of the needle insertion angle.
(二)技术方案(II) Technical solution
为实现以上目的，本实用新型通过以下技术方案予以实现：一种麻醉注射用辅助定位器，包括套于注射器上的固定环，且固定环上螺纹连接有可限制其移动的旋杆，所述固定环外壁套接有可滑动的固定杆，固定杆底端固定有连接杆，连接杆外壁套设有套筒，套筒内插入有可限制连接杆转动的卡杆，套筒底部连接有用于粘肤的固定组件。To achieve the above objectives, the utility model is implemented through the following technical solutions: an auxiliary positioner for anesthesia injection, including a fixing ring sleeved on the syringe, and a rotating rod that can limit its movement is threadedly connected to the fixing ring, a slidable fixing rod is sleeved on the outer wall of the fixing ring, a connecting rod is fixed to the bottom end of the fixing rod, a sleeve is sleeved on the outer wall of the connecting rod, a clamping rod that can limit the rotation of the connecting rod is inserted into the sleeve, and a fixing component for sticking to the skin is connected to the bottom of the sleeve.
进一步，所述连接杆外壁及套筒内壁均开设有与卡杆相适配的卡孔，当卡杆插入两个相对应的半个卡孔内，即可限制连接杆的旋转，进而也限定了固定杆与固定组件的相对角度，便于进行不同注射方法时对针头进入皮肤的角度进行辅助固定。Furthermore, the outer wall of the connecting rod and the inner wall of the sleeve are both provided with a clamping hole adapted to the clamping rod. When the clamping rod is inserted into two corresponding half clamping holes, the rotation of the connecting rod can be restricted, thereby also limiting the relative angle between the fixing rod and the fixing assembly, thereby facilitating the auxiliary fixation of the angle at which the needle enters the skin when performing different injection methods.
进一步，所述卡孔的数量有六个且以套筒的轴线为圆心环形阵列,使固定注射器的固定环可呈多角度固定，方便辅助多种注射方法。Furthermore, the number of the clamping holes is six and they are arranged in a circular array with the axis of the sleeve as the center, so that the fixing ring for fixing the syringe can be fixed at multiple angles, which is convenient for assisting various injection methods.
进一步，所述固定组件包括与套筒连接的连接座，连接座底部粘接有硅胶片，用于连接座与患者皮肤间的空隙，提高固定效果，连接座底部开设有吸气腔，吸气腔内设有与其相适配的活塞板，所述连接座顶部螺纹连接有与活塞板活动连接的螺杆，活塞板与螺杆的具体连接结构为，活塞板顶部设有连接筒，螺杆底端插入连接筒内并固定有防脱块，螺杆与连接筒转动连接。当连接座紧贴患者皮肤时，旋转螺杆带动活塞板向远离患者皮肤的一侧移动，即可使接触处产生负压，进而将连接座固定于患者皮肤处，操作简便，可多次使用。Furthermore, the fixing assembly includes a connecting seat connected to the sleeve, a silicone sheet is bonded to the bottom of the connecting seat, which is used to fill the gap between the connecting seat and the patient's skin to improve the fixing effect, an air suction cavity is provided at the bottom of the connecting seat, a piston plate adapted thereto is provided in the air suction cavity, a screw movably connected to the piston plate is threadedly connected to the top of the connecting seat, and the specific connection structure between the piston plate and the screw is that a connecting cylinder is provided at the top of the piston plate, the bottom end of the screw is inserted into the connecting cylinder and fixed with an anti-slip block, and the screw is rotatably connected to the connecting cylinder. When the connecting seat is in close contact with the patient's skin, the rotating screw drives the piston plate to move to the side away from the patient's skin, so that negative pressure is generated at the contact point, thereby fixing the connecting seat to the patient's skin, which is easy to operate and can be used multiple times.
进一步，所述固定组件包括与套筒连接的连接座，连接座底部设有粘接层。Furthermore, the fixing assembly includes a connecting seat connected to the sleeve, and an adhesive layer is provided at the bottom of the connecting seat.
进一步，所述卡杆与卡孔过盈配合，卡杆与连接座之间连接有拉绳，可防止卡杆不必要的掉落损失。Furthermore, the clamping rod and the clamping hole are interference fit, and a pull rope is connected between the clamping rod and the connecting seat, which can prevent the clamping rod from unnecessary falling loss.
