Description

[0002] Medical infusion injection dosing devices are commonly used in medical institutions to accurately control the infusion rate and volume of liquids such as medicines or nutrient solutions. These devices usually use syringe pumps to push the liquid in the syringe to achieve quantitative infusion.

[0003] In current syringe pump technology, due to differences in the physical properties of liquids, operators need to manually adjust the extension length of the injection rod according to the characteristics of the liquid. This leads to the instability of the distance between the syringe pump output end and the rod. In this case, the syringe pump is often unable to start injection immediately. Especially in emergency medical situations, this delay may affect the efficiency of treatment. In addition, the fixing effect of the syringe is often not stable enough, which will directly affect the accuracy and effectiveness of the injection. The traditional syringe operation process is relatively cumbersome and requires a large amount of data input, which increases the probability of operational errors and accuracy challenges.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0031] like Figure 1-6 As shown:

[0032] A medical infusion and injection quantitative device includes a console 101;

[0033] The syringe 102 is arranged above the console 101, and the console 101 is provided with a fixing mechanism 3 for supporting and fixing the syringe 102;

[0034] A scanner 104 is provided above the console 101 and is used to monitor the specific model of the syringe 102 in real time. A bracket 103 is fixedly mounted on the upper surface of the console 101 near the syringe 102. The scanner 104 is fixedly mounted on the top of the bracket 103 and corresponds to the syringe 102.

[0035] The fixing mechanism 3 is mounted on the console 101 and is used to flexibly and immediately drive the piston push rod of the syringe 102 to push quantitatively;

[0036] The adjustable pushing mechanism 2 includes a moving plate 203 and an electric telescopic push rod 201 for driving the moving plate 203 to move. An electromagnet 204 is fixedly mounted on the upper surface of the moving plate 203, and a push plate 208 is provided on the electromagnet 204.

[0037] The adjustable pushing mechanism 2 also includes a first limiting rod 202 fixed to the inside of the console 101 and arranged symmetrically. The movable plate 203 slides on the surface of the two groups of first limiting rods 202 through the first movable hole. The electric telescopic push rod 201 is fixedly installed inside the console 101, and the output end of the electric telescopic push rod 201 is fixedly connected to the movable plate 203 through an L-shaped block. A second limiting rod 209 arranged symmetrically is provided above the two groups of first limiting rods 202. The second limiting rod 209 is fixedly connected to the console 101. A moving block 205 is provided above the magnet 204, and an adsorption plate 207 slides inside the moving block 205. A first spring 206 arranged symmetrically is fixed between the adsorption plate 207 and the moving block 205. A push plate 208 is fixed to the upper surface of the moving block 205. The moving block 205 slides on two sets of second limit rods 209 through the second moving hole. A rectangular opening adapted to the push plate 208 is provided on the top of the console 101. The push plate 208 can slide in the rectangular opening provided in the console 101. The adsorption plate 207 is made of a magnetically attracted material.

[0038] The U-shaped plate 303 is provided with a sliding groove adapted to the locking block 309. The locking block 309 can slide in the sliding groove provided in the U-shaped plate 303. The locking block 309 is designed with an inclined structure.

[0039] The lower surface of the lower pressing plate 305 is provided with an arc-shaped groove for increasing the contact area with the syringe 102;

[0040] An adjusting screw 312 is rotatably mounted in the console 101 via a bearing. A square block is fixed to the bottom of the V-shaped seat 302, and the square block is threadedly connected to the adjusting screw 312 via a threaded hole. A strip opening is provided on the top of the console 101 to match the square block, and the square hole can slide within the strip opening of the console 101.

[0041] A laser rangefinder corresponding to the movable plate 203 is fixedly installed inside the console 101 .

[0042] In this embodiment, when using the medical infusion injection quantitative device, the syringe barrel of the syringe 102 should be placed on the V-shaped seat 302. The V-shaped seat 302 adopts a V-shaped structure design, which can adapt to the diameters of syringe barrels 102 of different diameters for engagement, thereby achieving left and right limit, further improving the practicality of this structure;

[0043] At the same time, the needle seat piece of the syringe barrel of the syringe 102 is clamped in the clamping groove of the clamping seat 301, thereby limiting the front and rear positions of the syringe 102;

[0044] like Figure 5 As shown, the user should then hold the handle 304, thereby aligning the two ends of the U-shaped plate 303 with the locking holes 311 opened at the two ends of the V-shaped seat 302, and then press the U-shaped plate 303 so that the two ends of the U-shaped plate 303 are inserted into its locking holes 311. During this process, the locking block 309 is squeezed by the V-shaped seat 302, causing the locking block 309 to move into the interior of the U-shaped plate 303. At the same time, the third spring 310 is compressed so that the locking block 309 is completely compressed into the U-shaped plate 303 until the locking block 309 passes through the locking hole 311 opened in the V-shaped seat 302. At the same time, the bottom of the interference block 308 is in contact with the top of the V-shaped seat 302, and the U-shaped plate 303 is limited by the interference block 308.

[0045] One side of the locking block 309 is provided with an inclined surface structure, which can play an extrusion guide role;

[0046] Subsequently, the V-shaped seat 302 releases the squeeze on the locking block 309. At this time, the third spring 310 rebounds, driving the locking block 309 to partially extend. Through the position limitation of the locking block 309 and the abutment block 308, the connection and locking between the U-shaped plate 303 and the V-shaped seat 302 are achieved.

[0047] During this process, when the U-shaped plate 303 is plugged in, the lower pressing plate 305 is blocked by the syringe 102, and the distance between the U-shaped plate 303 and the lower pressing plate 305 is continuously reduced, thereby achieving compression of the telescopic rod 306 and the second spring 307. The setting of the telescopic rod 306 increases the stability of the connection between the lower pressing plate 305 and the U-shaped plate 303. The second spring 307 in the compressed state elastically rebounds, thereby driving the lower pressing plate 305 to apply downward pressure to the syringe 102, stably clamping the syringe 102 in the V-shaped seat 302, achieving upper and lower limit locking of the syringe 102, thereby ensuring the stability of the placement of the syringe 102;

[0048] Prior to this, by rotating the adjusting screw rod 312, the square block is driven to slide in the strip groove provided on the console 101. The setting of the strip groove can limit the square block and ensure the stability of the movement of the V-shaped seat 302. This structure can adjust the position of the V-shaped seat 302 and can flexibly adjust the distance between the V-shaped seat 302 and the holder 301 according to the length of the syringe 102, so that the V-shaped seat 302 is located at the center of the syringe 102, which can provide better stable support.

[0049] like Figure 6 As shown, due to the different amounts of solution inside the syringe 102, the position of the piston push rod is different. After the syringe 102 is fixed, the push plate 208 is slid, thereby driving the moving block 205 to slide on the surface of the second limit rod 209, and at the same time driving the adsorption plate 207 to move synchronously until the push plate 208 contacts one end of the piston push rod of the syringe 102. By pressing the control button of the console 101, the electromagnet 204 is then powered, and the magnetism generated by the electromagnet 204 adsorbs the adsorption plate 207, so that the adsorption plate 207 is adsorbed and fixed to the electromagnet 204, and at the same time, the first spring 206 is stretched. The setting of the first spring 206 can drive the adsorption plate 207 to separate when the electromagnet 204 is powered off, thereby avoiding the adsorption plate 207 causing wear on the electromagnet 204 when the push plate 208 moves. At the same time, it has a buffering effect when the adsorption plate 207 moves downward;

[0050] Next, turn on the scanner 104 on the bracket 103. The specifications of the syringe 102 can be automatically identified through the laser scanning of the scanner 104. The operator inputs the required injection volume through the console 101, and the console 101 automatically controls the movement of the corresponding distance according to the input injection volume. The operation of the electric telescopic push rod 201 drives the movable plate 203 to move on the first limit rod 202, and drives the electromagnet 204 to move synchronously. Since the electromagnet 204 and the adsorption plate 207 are adsorbed and fixed, the push plate 208 will also move synchronously. The push plate 208 drives the piston push rod of the syringe 102 to push, thereby pushing out the liquid inside the syringe 102;

[0051] During the injection process, the laser rangefinder monitors the position movement of the movable plate 203 in real time. The laser rangefinder determines the distance by emitting laser pulses and measuring the returned reflected light, ensuring accurate control of the injection volume;

[0052] This solution has the ability to respond to emergency medical situations. Regardless of how the liquid properties change, resulting in different extension lengths of the piston push rod, the injection process can be quickly initiated, effectively improving treatment efficiency. The precise fixing design significantly enhances the stability of the syringe 102, thereby ensuring the accuracy and reliability of the injection process and avoiding the problem of inaccurate injection due to unstable fixation. The use of automatic recognition technology can accurately identify the diameter model of the syringe and accurately control the movement of the electric telescopic push rod 201 based on the injection volume input by the console 101, thereby ensuring the accuracy of the injection dose. In addition, the real-time monitoring function of the laser rangefinder further improves the accuracy of the injection process and effectively reduces the errors that may be caused by human operation. The automated design of the system eliminates tedious manual adjustment steps, significantly improves operational efficiency, and achieves rapid response in emergency medical situations, improving overall treatment efficiency.

[0053] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention.
