[0002] A syringe is a common laboratory and medical device. Its structure includes a barrel, piston, graduated sleeve, and connector. It has graduations and can accurately measure the volume of a solution. It is characterized by its simple structure, accurate quantification, and ease of operation, making it suitable for hospitals, research, teaching, and clinical research.

[0003] Ciprofloxacin is a broad-spectrum antibiotic belonging to the quinolone class of antibacterial drugs. It is mainly used to treat various infections caused by susceptible bacteria and is primarily administered intravenously.

[0004] Currently, most syringes used are disposable. However, when injecting ciprofloxacin, it is necessary to control the dosage. If the dosage is controlled by manually pushing the piston handle during the injection process and relying solely on the graduated sleeve to judge and control the dosage, it is difficult to accurately control the amount of drug injected. Summary of the Invention

Support plates are fixedly connected to the outer walls of both ends of the hinged sleeve plate. Sleeves are attached to one side of the top of each of the two support plates. Arc-shaped abutments are movably fitted onto the top of each of the two sleeves. The tops of each of the two arc-shaped abutments can intermittently fit tightly against the opening of the graduated syringe. A tension snap-fit ​​structure is provided between each of the two sleeves and the two support plates for positioning the two arc-shaped abutments after they are stretched. A clamping and limiting structure is provided between the bottom side walls of the two support plates and the two side plates of the graduated syringe.

[0009] Preferably, each of the tension snap-fit ​​structures includes a vertical cylinder fixedly connected to the top of the support plate, and a multi-section telescopic rod is fixedly connected between the outer wall of the top of the vertical cylinder and the inner wall of the top of the sleeve, and multiple connecting shafts are fixedly connected through the two sides of the vertical cylinder.

[0010] Preferably, an arc-shaped plate is movably sleeved on both ends of each connecting shaft, and a torsion spring is fixedly connected between the inner walls of both ends of the arc-shaped plate and the two sides of the shaft. Multiple arc-shaped grooves are formed in the inner walls of both ends of the sleeve, and the arc-shaped plate can slide and engage with the inner wall of each corresponding arc-shaped groove.

[0011] Preferably, arc-shaped grooves are formed in the inner walls of the other two ends of the sleeve, the outer wall of the arc-shaped plate and the inner wall of the sleeve can be slidably connected, and a stop plate is fixedly connected to the outer wall of the vertical cylinder, the top outer wall of the stop plate and the bottom outer wall of the arc-shaped plate are connected in a close fit.

[0012] Preferably, the clamping and limiting structure includes an L-shaped bracket fixedly connected to the outer wall of the bottom end of the support plate. An L-shaped telescopic rod is attached to one side plate of the top end of the L-shaped bracket. An elastic collar is tightly sleeved on the body of the L-shaped telescopic rod. The elastic collar is fixedly connected to the top plate of the L-shaped bracket.

[0013] Preferably, an elastic collar II is fixedly connected to the top end of the L-shaped telescopic rod, and the elastic collar II is tightly fitted with the cylinder plate of the graduated syringe. A rectangular rigid plate is fixedly connected to the top outer wall of the elastic collar II, and an elastic telescopic component is fixedly connected to the top end of the rectangular rigid plate.

[0014] Preferably, a U-shaped groove plate is fixedly connected to the top of the elastic telescopic member, and long connecting plates are hinged to both sides of the U-shaped groove plate, and bevel plates are hinged to the other side of the two long connecting plates.

[0015] Preferably, a shorting plate is hinged to the bottom plate of each of the two beveled plates, and a double-eared corner plate is hinged to the other side plate of each of the two shorting plates.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] This invention achieves precise positioning of the piston handle at multiple intervals through the cooperation of the arc-shaped plate, arc-shaped groove and torsion spring of the metering adjustment part of the handle. When pushing, the arc-shaped abutment and the syringe nozzle are used to limit the pressure and avoid pushing too much or too little cyclopropionate. When pulling up the arc-shaped abutment, the piston handle scale can be aligned in real time, making the adjustment efficient.

[0019] The sleeve reset only requires a 90-degree twist to disengage from the arc-angle groove limiter, making it flexible to operate. The clamping and limiting structure uses rubber protrusions to clamp the finger joints of medical staff. The natural rubber material increases friction and prevents the hand from slipping when pushing the piston, reducing the risk of medical accidents. Attached Figure Description

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] like Figures 1 to 9 As shown, the present invention provides a cyclopropane syringe with an adjustable handle, including a graduated syringe 1, a piston handle 101 that is slidably connected to the inner wall of the graduated syringe 1, the piston handle 101 having graduated values ​​on its handle, and a handle metering adjustment part 2 being provided between the graduated syringe 1 and the piston handle 101.

[0034] The handle metering adjustment unit 2 includes a hinged sleeve plate 201 that can be tightly fitted onto the piston handle 101. Support plates 204 are fixedly connected to the outer walls of both ends of the hinged sleeve plate 201. Sleeves 205 are attached to the top side plates of the two support plates 204. Arc-shaped supports 206 are movably fitted onto the top cylinder of the two sleeves 205. The tops of the two arc-shaped supports 206 can intermittently fit tightly against the opening of the graduated syringe 1. A tension snap-fit ​​structure is provided between the two sleeves 205 and the two support plates 204 for positioning the two arc-shaped supports 206 after tensioning. A clamping and limiting structure is provided between the bottom side walls of the two support plates 204 and the two side cylinder plates of the graduated syringe 1.

[0035] The handle metering adjustment unit 2 also includes a slot 202 formed in one end of the hinged sleeve plate 201. A locking block 203 can be tightly locked in the inner wall of the slot 202, and the other end of the locking block 203 is fixedly connected to the other end of the hinged sleeve plate 201.

[0036] The above scheme is adopted as follows: By placing the hinged sleeve 201 on the handle of the piston handle 101, and by having the locking block 203 fixed on the hinged sleeve 201 engage with the corresponding locking groove 202, a tight locking force is formed on the handle of the piston handle 101. This pulls the arc-shaped abutment 206 upward, causing the sleeve 205 to move upward. The process of manually pulling the arc-shaped abutment 206 upward can be constantly aligned with the scale value on the piston handle 101, thereby controlling the amount of cyclopropene pushed by the piston handle 101 in the graduated syringe 1. When the piston handle 101 is manually pushed, the arc-shaped abutment 206, which has been passively moved upward and positioned in advance, provides a strong abutment force when it contacts the opening of the graduated syringe 1, preventing the piston handle 101 from continuing to be passively pushed in the graduated syringe 1, thus achieving the effect of pushing only the required amount of cyclopropene.

[0037] Each tension-locking structure includes a vertical cylinder 207 fixedly connected to the top of the support plate 204. A multi-section telescopic rod 208 is fixedly connected between the outer wall of the top of the vertical cylinder 207 and the inner wall of the top of the sleeve 205. Multiple connecting shafts 209 are fixedly connected through both sides of the vertical cylinder 207. An arc-shaped plate 210 is movably sleeved on both ends of each connecting shaft 209. The inner walls of both ends of the arc-shaped plate 210 and the two sides of the shaft 209 are fixedly connected. A torsion spring 211 is connected to the sleeve 205. Multiple arc-shaped grooves 212 are provided in the inner walls of both ends of the sleeve 205. The arc-shaped plate 210 can be fitted and slidably engaged with the inner wall of each corresponding arc-shaped groove 212. Arc-shaped sliding grooves 2121 are provided in the inner walls of the other two ends of the sleeve 205. The outer wall of the arc-shaped plate 210 and the inner wall of the sleeve 205 can be fitted and slidably connected. A stop plate 213 is fixedly connected to the outer wall of the vertical cylinder 207. The top outer wall of the stop plate 213 and the bottom outer wall of the arc-shaped plate 210 are fitted and connected.

[0038] The above solution is adopted: such as Figure 6 , Figure 7 and Figure 8As shown, the passively moving sleeve 205 will drive the stretching multi-section telescopic rod 208 to move upward in a limited manner only under the positioning of the vertical cylinder 207. During the upward movement of the sleeve 205, the corresponding arc-shaped plate 210 will fluctuate, causing it to tilt on the connecting shaft 209 as the sleeve 205 moves upward. During the passive tilting of the arc-shaped plate 210, the torsion spring 211 installed with it will rotate and deform, winding around the connecting shaft 209. This causes the arc-shaped plate 210 to repeatedly swing and tilt, sequentially engaging into its corresponding arc-shaped groove 212. The process of manually pulling the arc-shaped abutment 206 upward can be constantly aligned with the scale value on the piston handle 101, thereby controlling the amount of propylene pushed by the piston handle 101 in the scale syringe 1. After being adjusted to the appropriate position, the arc-shaped plate 210 will return to the horizontal state through the action of the torsion spring 211, thus contacting... The piston handle 206 is attached to the abutment plate 213, providing bottom support for the arc-shaped plate 210. When the piston handle 101 is manually pushed, the arc-shaped abutment 206, which has been passively moved upward and positioned in advance, comes into contact with the opening of the graduated syringe 1. This provides strong resistance to the arc-shaped abutment 206, preventing the piston handle 101 from being passively pushed further inside the graduated syringe 1. This achieves the effect of pushing only the required amount of propylene. The arc-shaped abutment 206, which can be passively pulled upward at will, allows for precise adjustment of the piston handle 101's push at multiple intervals. When the sleeve 205 wants to move downward and reset, it is only necessary to apply force to twist the sleeve 205 when the arc-shaped plate 210 is tilted upward, causing it to rotate 90 degrees. At this time, the arc-shaped plate 210 will rotate tightly against the inner wall of the sleeve 205 until it enters the area of ​​the arc-shaped groove 2121. Without the limiting barrier of the arc-shaped groove 212, the sleeve 205 will move downward and reset directly.

[0039] The clamping and limiting structure includes an L-shaped bracket 214 fixedly connected to the outer wall of the bottom end of the support plate 204. An L-shaped telescopic rod 215 is attached to one side plate of the top end of the L-shaped bracket 214. An elastic collar 216 is tightly sleeved on the body of the L-shaped telescopic rod 215. The elastic collar 216 is fixedly connected to the top plate of the L-shaped bracket 214. An elastic collar 217 is fixedly connected to the top body of the L-shaped telescopic rod 215. The elastic collar 217 is tightly sleeved on the cylinder plate of the graduated syringe 1. A rectangular rigid plate 218 is fixedly connected to the outer wall of the top end of the elastic collar 217. An elastic telescopic component is fixedly connected to the top plate of the rectangular rigid plate 218. 219. A U-shaped groove plate 220 is fixedly connected to the top of the elastic telescopic component 219. Long connecting plates 221 are hinged to both sides of the U-shaped groove plate 220. An angled plate 222 is hinged to the other side of the two long connecting plates 221. A short connecting plate 223 is hinged to the bottom of the two angled plates 222. A double-eared angle plate 224 is hinged to the other side of the two short connecting plates 223. The bottom ends of the two double-eared angle plates 224 are fixedly connected to the top outer wall of the rectangular rigid plate 218. Multiple sets of rubber protrusions 225 are fixedly connected to the top outer wall of the two angled plates 222. Each rubber protrusion 225 is made of natural rubber.

[0040] The above solution is adopted: such as Figure 6 and Figure 9 As shown, when the piston handle 101 is pushed upward, it drives the L-shaped telescopic rod 215, which is limited by the elastic collar 216, to extend and retract via the support plate 204 and the L-shaped bracket 214. Before this, the index and middle fingers of the medical staff are crossed on both sides of the cylinder plate of the graduated syringe 1. When the index and middle fingers press the U-shaped groove plate 220 respectively, it compresses the elastic telescopic member 219 at the bottom, causing the rod to retract. At the same time, the downward movement of the U-shaped groove plate 220 pulls down the long connecting plates 221 on both sides, causing them to change angle, thereby synchronously pulling down the angled plate hinged to it. 222, so that the two angled plates 222 form a V-shape. When the shape of the angled plates 222 changes at the same time, it will cause the short connecting plate 223 on the double ear angled plates 224 to tilt as well, increasing its tilt angle. As a result, the aforementioned V-shaped angled plates 222 will cause multiple rubber protrusions 225 on the plate to contact the knuckles on the human body, clamping and limiting them. The natural rubber material increases the friction between the finger and the human body, so that when using the graduated syringe 1 and piston handle 101 to push the medicine, it will not slip with the cylinder and cause medical accidents.

[0041] One point that needs to be added is that the curvature of the upper and lower corners of the arc corner groove 212 is not the same, with the lower arc corner being larger than the upper arc corner. This allows the arc corner plate 210 to tilt upwards, but it can also clamp and resist pressure on the arc corner plate 210 in the lateral state.

[0042] The elastic collar 216 and elastic collar 217 that are installed in contact with the upper and lower parts of the L-shaped telescopic rod 215 can be disassembled at any time. The installation method of the elastic collar 217 and the hinge plate 201 on the piston handle 101 and the sleeve 205 makes it easy to disassemble the whole and reinstall it on another syringe for repeated use, thereby improving the flexibility of the equipment.

[0043] The working principle and usage process of this invention are as follows: By placing the hinged sleeve 201 on the handle of the piston handle 101, the locking block 203 fixed on the hinged sleeve 201 is engaged with the corresponding slot 202, forming a tight locking force on the handle of the piston handle 101. This pulls the arc-shaped abutment 206 upward, causing the sleeve 205 to move upward. The passively moving sleeve 205 will cause the multi-section telescopic rod 208 to be stretched, so that it can only move upward in a limited manner under the positioning of the vertical cylinder 207. During the upward movement of the sleeve 205, the corresponding arc-shaped plate 210 will fluctuate, causing it to tilt on the connecting shaft 209 as the sleeve 205 moves upward. During the passive tilting of the arc-shaped plate 210, the torsion spring 211 installed with it will rotate and deform, winding around the connecting shaft 209. This causes the arc-shaped plate 210 to repeatedly swing and tilt, sequentially engaging with its corresponding... After being adjusted to the appropriate position within the arc-shaped groove 212, the arc-shaped plate 210 will return to a horizontal state driven by the torsion spring 211, thereby contacting and adhering to the abutment plate 213, which provides bottom support for the arc-shaped plate 210. Then, when the piston handle 101 is manually pushed, the arc-shaped abutment 206, which has been passively moved upward and positioned in advance, contacts the opening of the graduated syringe 1, providing strong abutment force to the arc-shaped abutment 206, preventing the piston handle 101 from continuing to be passively pushed within the graduated syringe 1. When the sleeve 205 wants to move downward and reset, it is only necessary to apply force to twist the sleeve 205 directly when the plate of the arc-shaped plate 210 is tilted upward, so that it rotates 90 degrees. At this time, the arc-shaped plate 210 will rotate tightly against the inner wall of the sleeve 205 until it enters the area of ​​the arc-shaped groove 2121. Without the limiting barrier of the arc-shaped groove 212, the sleeve 205 will move downward and reset directly.

[0044] When the piston handle 101 is pushed upward, it drives the L-shaped telescopic rod 215, which is limited by the elastic collar 216, to extend and retract via the support plate 204 and the L-shaped bracket 214. Before this, the index and middle fingers of the medical staff are crossed on both sides of the cylinder plate of the graduated syringe 1. When the index and middle fingers press the U-shaped groove plate 220 respectively, it compresses the elastic telescopic member 219 at the bottom, causing the rod to contract. At the same time, the downward movement of the U-shaped groove plate 220 pulls down the long connectors on both sides. Plate 221 is tilted to change its angle, which in turn pulls down the angled plate 222 that is hinged to it, so that the two angled plates 222 form a V-shape. At the same time, when the shape of the angled plates 222 changes, it will also cause the short plate 223 on the double eared plate 224 to tilt, increasing its tilt angle. As a result, the angled plates 222 that form a V-shape will cause multiple rubber protrusions 225 on the plate to contact the knuckles on which the human body is placed, clamping and limiting them.
