Description

Technical Field

[0001] This utility model relates to the field of injection pump technology, specifically to an electronic auxiliary device for quantitative control during injection. Background Technology

[0002] An infusion pump is a medical device consisting of a stepper motor, its driver, lead screw, and support. When in operation, the microcontroller system sends control pulses to make the stepper motor rotate, and the stepper motor drives the lead screw to convert the rotational motion into linear motion, which pushes the piston of the syringe to inject fluid, achieving a smooth and pulsation-free fluid transfer. An infusion pump is an injection device that can inject drugs into the body through intramuscular injection to achieve the purpose of treatment.

[0003] However, existing infusion pumps inject fluid by pushing the syringe plunger. This typically requires a worker to connect a tubing to the syringe outlet, allowing the fluid to flow through the tubing and a pre-installed needle. Once the syringe plunger moves to the inside of the syringe and all the fluid has been expelled, the syringe can no longer drive the fluid flow, and some fluid remains in the tubing, leading to waste. Therefore, this method does not meet the current requirements. To address this, we propose an electronic auxiliary device for quantitative control during injection. Utility Model Content

[0004] The purpose of this invention is to provide an electronic auxiliary device for quantitative control during injection, in order to solve the problem mentioned in the background art where the injection pump pushes the piston of the syringe to inject fluid. However, when using the injection pump, the operator usually needs to connect a tubing to the liquid outlet of the syringe so that the injection fluid enters the patient's body through the tubing and the pre-inserted needle inserted into the patient's body. When the syringe piston moves to the inside of the syringe and the injection fluid inside the syringe is completely discharged from the syringe, the syringe can no longer drive the injection fluid to flow, and some injection fluid will remain inside the tubing, which easily leads to waste.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an electronic auxiliary device for quantitative control during injection, comprising a control bracket:

[0006] A fixed bracket is fixedly installed on the front end face of one side of the control bracket, and a movable bracket is provided on the rear end face of one side of the control bracket.

A movable motor is fixedly installed on the upper end of both the movable bracket and the fixed bracket, and the rotation drive part of the movable motor is fixedly connected to the drive extrusion roller.

[0007] An extrusion screw is disposed at the lower end of the fixed bracket. The extrusion screw is rotatably connected to the fixed bracket via a bearing. The extrusion screw is threadedly connected to the movable bracket. A limit slide rod is fixedly installed at the upper end of the rear end face of the fixed bracket. The limit slide rod is slidably connected to the movable bracket via a slot. A heating wire is fixedly installed on the inner side of the control bracket. An extrusion motor is fixedly installed at the lower end of the front end face of the fixed bracket. The rotation drive part of the extrusion motor is fixedly connected to the extrusion screw.

[0008] Preferably, a conical silicone limiting sleeve is installed at the other end of the control bracket, and the conical silicone limiting sleeve is fixedly connected to the control bracket.

[0009] Preferably, a control microcontroller is mounted on the front end face of the control bracket, and the control microcontroller is fixedly connected to the control bracket.

[0010] Preferably, a storage battery is installed on the outside of the control bracket, and the storage battery is fixedly connected to the control bracket.

[0013] Preferably, a silicone clip is provided between the mounting bracket and the syringe body, the silicone clip is fixedly connected to the mounting bracket, and the silicone clip is connected to the syringe body through a slot.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model, by installing a drive extrusion roller in conjunction with a moving motor, enables the device to move stably outside the connecting hose, facilitating operator control of the device's position at the upper end of the connecting hose and making the device more flexible.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figure 1-4 One embodiment of this utility model provides: an electronic auxiliary device for quantitative control during injection, comprising a control bracket 1:

[0024] A fixed bracket 9 is fixedly installed on the front end face of one side of the control bracket 1. A movable bracket 10 is provided on the rear end face of one side of the control bracket 1. A drive squeezing roller 14 is rotatably installed on the inner side of both the movable bracket 10 and the fixed bracket 9. Installing the drive squeezing roller 14 so that it cooperates with the movable motor 12 can enable the device to move stably outside the connecting hose 6, making it easier for the operator to control the position of the device at the upper end of the connecting hose 6 and making the device more flexible. A movable motor 12 is fixedly installed at the upper end of both the movable bracket 10 and the fixed bracket 9. The rotation drive part of the movable motor 12 is fixedly connected to the drive squeezing roller 14.

[0025] The extrusion screw 16 is located at the lower end of the fixed bracket 9. Installing the extrusion screw 16 allows it to work in conjunction with the extrusion motor 15 to drive the extrusion roller 14, which in turn extrudes the connecting hose 6, thus changing the cross-sectional area of ​​the connecting hose 6 and consequently altering the amount of injection solution passing through it per unit time. This controls the amount of injection solution, enhancing the device's practicality. The extrusion screw 16 is rotatably connected to the fixed bracket 9 via bearings and to the movable bracket 10 via threads. A limit slide rod 11 is fixedly installed at the upper end of the rear end face of the fixed bracket 9, and it is slidably connected to the movable bracket 10 via a slot. A heating wire 17 is fixedly installed on the inner side of the control bracket 1, facilitating the heating of the injection solution to bring it closer to body temperature, making the device more comfortable and user-friendly. The extrusion motor 15 is fixedly installed at the lower end of the front end face of the fixed bracket 9, and its rotation drive is fixedly connected to the extrusion screw 16.

[0026] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 A conical silicone limiting sleeve 13 is installed at the other end of the control bracket 1. The conical silicone limiting sleeve 13 can ensure the stability of one end of the device on the connecting hose 6 and prevent the device from shaking at the upper end of the connecting hose 6, thus playing a limiting role. The conical silicone limiting sleeve 13 is fixedly connected to the control bracket 1. A control microcontroller 8 is installed on the front end of the control bracket 1 and is fixedly connected to the control bracket 1. A storage battery 18 is installed on the outside of the control bracket 1 and is fixedly connected to the control bracket 1. A connecting hose 6 is provided inside the control bracket 1. A syringe body 5 is installed at one end of the connecting hose 6 through a slot. A mounting bracket 3 is provided on the outside of the syringe body 5. An injection pump 2 is fixedly installed at the rear end of the mounting bracket 3. A transverse propulsion part 7 is provided on one side of the injection pump 2. A silicone block 4 is provided between the mounting bracket 3 and the syringe body 5. The silicone block 4 is fixedly connected to the mounting bracket 3 and the syringe body 5 through a slot. The injection pump 2 is electrically connected to the control microcontroller 8.

[0027] Working Principle: During use, the operator places the device over the connecting tubing 6, inserts the syringe body 5 into the mounting bracket 3, and connects the connecting tubing 6 to the syringe body 5. The operator then adjusts the position of the transverse propulsion section 7 so that it contacts the syringe body 5. Next, the injection pump 2 drives the transverse propulsion section 7 to move laterally, pushing the injection fluid inside the syringe body 5 into the connecting tubing 6, expelling air from inside the tubing 6. The operator then connects the connecting tubing 6 to the pre-installed needle inserted into the patient's body. During use, the operator, according to needs, uses the squeeze motor 15 to rotate the squeeze screw 16, thereby adjusting the distance between the two drive squeeze rollers 14, thus changing the amount of injection fluid passing through the connecting tubing 6 per unit time, achieving control over the injection volume. Simultaneously, the microcontroller 8 can periodically send signals to the injection pump 2 to control the advancement amplitude of the transverse propulsion section 7. When the liquid inside the syringe body 5 is completely injected, the moving motor 12 moves the device outside the connecting tubing 6, bringing it to the end of the connecting tubing 6 closest to the syringe body 5. Then, the squeeze motor 15 drives the squeeze screw... Rotating the screw 16 adjusts the two drive compression rollers 14 to tightly compress the connecting hose 6. Then, the moving motor 12 drives the drive compression rollers 14 to rotate, causing the device to move and compress outside the connecting hose 6, thus completely draining the injection fluid from inside the connecting hose 6 and preventing waste. The installation of the drive compression rollers 14 in conjunction with the moving motor 12 allows the device to move stably outside the connecting hose 6, facilitating operator control of the device's position at the upper end of the connecting hose 6 and making the device more flexible. Installing the compression screw 16 in conjunction with the compression motor 15... The drive extrusion roller 14 is moved to extrude the connecting hose 6, thereby changing the cross-sectional area of ​​the connecting hose 6 and thus changing the amount of injection solution passing through the connecting hose 6 per unit time. This allows for control of the injection solution volume, enhancing the practicality of the device. The installation of the heating wire 17 facilitates the heating of the injection solution, bringing it closer to human body temperature, making the device more comfortable and user-friendly. The installation of the conical silicone limit sleeve 13 ensures the stability of one end of the device on the connecting hose 6, preventing the device from shaking at the upper end of the connecting hose 6 and serving as a limit.
