Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a syringe fixing device for an electronic injection pump. Background Technology

[0002] An electronic infusion pump is a medical device used to precisely control the delivery of medications to a patient. The use of electronic infusion pumps can reduce human error and improve the safety and accuracy of drug infusion. They are widely used in various departments of hospitals, including operating rooms, intensive care units, and general wards, as well as for long-term drug treatment in patients' homes.

[0003] An existing syringe fixing device for an electronic infusion pump can only fix the outside of a single type of syringe and cannot accommodate multiple types of syringes. This limits the use of syringes inside the electronic infusion pump. Furthermore, when pushing the plunger to push the liquid inside the syringe, the syringe barrel and plunger are prone to slipping out of the electronic infusion pump, causing failure to push the liquid inside the syringe and affecting the treatment of the patient. Therefore, a syringe fixing device for an electronic infusion pump is proposed to solve the above-mentioned problems. Utility Model Content

It solves the problem that the device can only fix the outside of a single type of syringe, limiting the use of syringes inside the electronic injection pump. Furthermore, it addresses the issue that when pushing the plunger to push the liquid inside the syringe, the syringe barrel and plunger easily slip out of the electronic injection pump, causing failure to push the liquid inside the syringe and affecting patient treatment.

[0006] (II) Technical Solution

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] In the embodiments, by Figure 1-4 Presented is a syringe fixing device for an electronic injection pump. The present invention includes a fixing platform 1 and a sliding plate 8. A first cylinder 2 is fixedly connected to the top of the fixing platform 1. A mounting bracket 3 is fixedly connected to the outside of the first cylinder 2. A clamping plate 4 is rotatably connected inside the mounting bracket 3. A connecting plate 5 is fixedly connected to the output end of the first cylinder 2. A connecting rod 6 is rotatably connected inside the connecting plate 5 and rotatably connected to the inside of the clamping plate 4. Anti-slip pads 7 are fixedly connected to the inner sides of the two clamping plates 4. A second cylinder 9 is fixedly connected inside the sliding plate 8. A syringe body 11 is disposed inside the two clamping plates 4. A clamping piece 10 is fixedly connected to the output end of the second cylinder 9. The syringe body 11 includes a syringe barrel, a push rod slidably connected to the inside of the syringe barrel, and a needle connected to one end of the syringe barrel.

[0026] By activating the first cylinder 2, the connecting plate 5 is moved upward, and then the connecting rod 6 drives the clamping plate 4 to rotate towards the outside of the syringe body 11, thereby fixing the outside of the syringe body 11. The anti-slip pad 7 prevents the syringe barrel of the syringe body 11 from falling off the inside of the clamping plate 4 when liquid is pumped into the syringe body 11 with the push rod. Activating the second cylinder 9 causes the clamping plate 10 to move towards the outside of the push rod, thereby fixing the push rod. This facilitates the use of the push rod to push the liquid inside the syringe barrel, while preventing the push rod from separating from the sliding plate 8 and causing operational errors.

[0027] Specifically, refer to Figure 1 and Figure 4A support plate 12 is fixedly connected to the top of the fixed platform 1. A motor 13 is fixedly connected to the left side of the left support plate 12. A high-precision lead screw 14 is fixedly connected to the output shaft of the motor 13 and rotates internally with the support plate 12. The outer side of the high-precision lead screw 14 is threadedly connected to the sliding plate 8.

[0028] In this embodiment, the motor 13 is started, which causes the high-precision lead screw 14 to rotate. Subsequently, the sliding plate 8 slides on the outside of the high-precision lead screw 14. The sliding plate 8 drives the push rod to slide left and right inside the syringe, thereby pushing the liquid inside the syringe.

[0029] Specifically, refer to Figure 1 , Figure 2 and Figure 4 Synchronous rods 15 are fixedly connected to the inner sides of the two support plates 12, and the sliding plate 8 is slidably connected to the inside of the synchronous rods 15.

[0030] In this embodiment, the synchronizing rod 15 limits the sliding of the sliding plate 8 to prevent the sliding plate 8 from rotating along with the rotation of the high-precision lead screw 14, thereby allowing the sliding plate 8 to drive the push rod to slide stably on the outside of the high-precision lead screw 14.

[0031] Specifically, refer to Figure 1 A support platform 16 is fixedly connected to the top of the fixed platform 1. The support platform 16 has a groove inside, and the syringe body 11 is located inside the groove.

[0032] In this embodiment, the support platform 16 supports the bottom of the syringe body 11, thereby ensuring that the liquid inside the syringe body 11 can be stably pushed.

[0033] Specifically, refer to Figure 1 An operating console 17 is provided on the outside of the fixed platform 1. The operating console 17 includes a number keypad 18 and a display screen 19.

[0034] In this embodiment, the high-precision delivery of liquid inside the syringe body 11 is controlled by pressing the number key 18 and operating the display screen 19, thereby meeting the high-precision requirements of medical treatment.

[0035] Specifically, refer to Figure 1 A display screen 19 is provided on the rear side of the fixed platform 1, and a number keypad 18 is provided on the right side of the display screen 19. The operating table 17 is embedded and fixed to the fixed platform 1.

[0036] Working principle:

[0037] First: by activating the first cylinder 2, the connecting plate 5 is moved upward, and then the connecting rod 6 drives the clamping plate 4 to rotate towards the outside of the syringe body 11, thereby fixing the outside of the syringe body 11. The anti-slip pad 7 prevents the syringe barrel of the syringe body 11 from falling off the inside of the clamping plate 4 when liquid is pumped into the syringe body 11 with the push rod.

[0038] Then: the second cylinder 9 is activated, which drives the clamping plate 10 to move towards the outside of the push rod, thereby fixing the push rod and making it easier to push the liquid inside the syringe with the push rod. At the same time, it prevents the push rod from separating from the sliding plate 8 and causing operational errors. The motor 13 is activated, which causes the high-precision lead screw 14 to rotate. Subsequently, the sliding plate 8 slides outside the high-precision lead screw 14. The sliding plate 8 drives the push rod to slide left and right inside the syringe, thereby pushing the liquid inside the syringe.
