Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and more specifically, to a syringe for intravenous injection. Background Technology
[0002] Intravenous injection syringes are known to be used to directly inject liquid substances such as drugs, liquids, or blood into veins. In clinical applications, they are mainly used for rapid drug administration, such as emergency drugs and anesthetics. They are characterized by rapid onset of action and precise dosage. However, when performing intravenous injections, medical staff not only need to keep the needle interface of the syringe stable, but also need to control the injection speed to avoid problems such as heart failure or pulmonary edema caused by excessively fast injection speed.
[0003] However, in actual use, existing syringes require manual fixation and lack fixation measures. If the interface between the syringe and the needle becomes loose, it can easily cause extravenous leakage and drug contamination. Moreover, if it is manually fixed, the injection speed can easily be too fast, which may lead to toxic reactions. Therefore, this utility model proposes an intravenous injection syringe as a further improvement. Utility Model Content
[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an intravenous injection syringe to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: an intravenous injection syringe, comprising an injection needle tube, an injection port end of the injection needle tube being fixedly connected to an injection tubing, a scalp needle being fixedly connected to the end of the injection tubing away from the injection needle tube, and an adhesive tape fixing mechanism being fixedly installed on the outer wall of the injection tubing. The tape fixing mechanism includes: a hose clamp, an operating handle, a lower base, and an upper cover; The tubing sleeve is fixedly installed on the outer wall of the injection tubing, the operating handle is fixedly installed on the top of the tubing sleeve, and the two lower bases are respectively fixedly installed on both sides of the tubing sleeve. The top edge of the lower base is rotatably connected to the upper cover. The lower base and the upper cover are provided with medical adhesive rolls for fixing and rolled into a cylindrical shape.
[0006] Furthermore, the upper cover has a strip-shaped adhesive strip outlet on the outer side away from the tubing sleeve, which facilitates the passage of medical adhesive rolls.
[0007] Furthermore, a limiting plate is fixedly installed on the outer side of the lower base, and a serrated plate is installed on the outer side of the lower base and at the bottom of the limiting plate.
[0008] Furthermore, the limiting plate has a strip-shaped limiting groove inside to facilitate the passage of medical adhesive rolls.
[0009] Furthermore, the adhesive strip outlet, the limiting plate, the serrated plate, and the limiting groove are all parallel to each other.
[0010] Furthermore, a silicone patch is attached to the bottom of the lower base.
[0011] The technical effects and advantages of this utility model are as follows: Compared with existing technologies, by setting up an adhesive tape fixing mechanism, after the scalp vein needle is inserted, the medical adhesive tape is pulled out from the adhesive tape fixing mechanism on both sides to fix the injection tube to the patient's skin, preventing the scalp vein needle from falling off the patient's arm, reducing the difficulty of the nurse's work, and at the same time ensuring the nurse's stability and focus when administering the injection.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0018] As attached Figure 1 and attached Figure 2The illustrated intravenous injection syringe includes an injection needle 1, with an injection tube 2 fixedly connected to the injection port end of the injection needle 1, and a scalp vein needle 3 fixedly connected to the end of the injection tube 2 away from the injection needle 1. Among them, the injection needle 1 uses a 2ml syringe; Among them, the conventional scalp needle 3 can be shortened, which makes the scalp needle 3 more secure; The outer wall of the injection hose 2 is fixedly installed with a tape fixing mechanism 4; The tape fixing mechanism 4 includes: hose clamp 401, operating handle 402, lower base 403 and upper cover 404; The hose clamp 401 is fixedly installed on the outer wall of the injection hose 2. The internal structure of the hose clamp 401 is adapted to the external structure of the injection hose 2, and the injection hose 2 and the hose clamp 401 can be connected by a snap-fit method; the inner wall of the hose clamp 401 is fitted with a silicone protective soft layer, and both sides of the operating handle 402 are provided with grooves for easy pinching.
[0019] The operating plate 402 is fixedly installed on the top of the hose clamp 401, and the two lower bases 403 are fixedly installed on both sides of the hose clamp 401 respectively, that is, the two lower bases 403 are symmetrically distributed from left to right. The top edge of the lower base 403 is rotatably connected to the upper cover 404. The lower base 403 and the upper cover 404 can be rotatably connected by a hinge component; The lower base 403 and the upper cover 404 are provided with a medical adhesive roll 405 for fixing and rolled into a cylindrical shape; and the medical adhesive roll 405 rotates inside the lower base 403 and the upper cover 404.
[0020] In a preferred embodiment, as shown in the appendix Figure 3 and attached Figure 4 As shown, the outer side of the upper cover 404 away from the tubing sleeve 401 has a strip-shaped adhesive strip outlet 406 for the medical adhesive roll 405 to pass through; that is, the medical adhesive roll 405 and the adhesive strip outlet 406 are slidably connected.
[0021] In a preferred embodiment, as shown in the appendix Figure 3 and attached Figure 4 As shown, a limiting plate 407 is fixedly installed on the outer side of the lower base 403, and a serrated plate 408 is installed on the outer side of the lower base 403 and at the bottom of the limiting plate 407.
[0022] The serrated plate 408 can rotate, thus easily using the shape of the serrated plate 408 to cut the medical adhesive roll 405. In a preferred embodiment, as shown in the appendix Figure 3 and attached Figure 4 As shown, the limiting plate 407 has a strip-shaped limiting groove 409 inside, which facilitates the passage of the medical adhesive roll 405; that is, the medical adhesive roll 405 is slidably connected to the limiting groove 409.
[0023] In a preferred embodiment, as shown in the appendix Figure 3 and attached Figure 4 As shown, the adhesive strip outlet 406, the limiting plate 407, the serrated plate 408, and the limiting groove 409 are all parallel to each other, so that the medical adhesive roll 405 can smoothly enter the limiting groove 409 from the adhesive strip outlet 406.
[0024] In a preferred embodiment, as shown in the appendix Figure 3 and attached Figure 4 As shown, a silicone patch is attached to the bottom of the lower base 403 so that the lower base 403 can fit the skin.
[0025] The working principle of this utility model is as follows: In use, the injection tubing 2 is connected to the injection needle tube 1. Then, the tubing sleeve 401 in the tape fixing mechanism 4 is fixedly connected to the outside of the injection tubing 2. One end of the medical adhesive roll 405 is pulled out from the adhesive strip outlet 406 and then passed downward through the limiting groove 409 in the limiting plate 407. A section of the medical adhesive roll 405 is pulled out for later use. Next, the nurse holds the needle handle and first inserts the scalp vein needle 3 into the patient's skin vein. Then, the pulled-out medical adhesive roll 405 is attached to the skin to fix it, which can fix and limit the scalp vein needle 3, prevent it from moving back and forth and falling off, avoid extravenous leakage, and ensure the stability and focus of the nurse when administering the injection. Since the pulled-out section of the medical adhesive roll 405 will change the pulling direction when it is attached to the patient's skin, the medical adhesive roll 405 is limited and fixed by the limiting plate 407 and will not slip.
[0026] After use, flip the serrated plate 408 to cut off the adhesive part of the medical adhesive roll 405, then remove the scalp needle 3 and peel off the medical adhesive paper on the skin. When it is necessary to replace the medical adhesive roll 405, open the lower base 403 and the upper cover 404, and replace the medical adhesive roll 405 again.
