Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a device for assisting syringe injection. Background Technology

[0002] In the field of medical care, especially for dual-target injections for breast cancer patients, nurses typically need to inject continuously for 5 minutes while maintaining an injection angle of 15 to 30 degrees. This procedure requires nurses to be highly focused throughout the injection process to ensure the accuracy and stability of the injection angle, which is physically and mentally taxing. Furthermore, prolonged hand-held injection may lead to slight deviations in the injection angle, thus affecting the treatment outcome.

[0003] Furthermore, there is currently a lack of devices that can effectively assist nurses in precisely controlling the injection angle during the injection process. Existing injection methods largely rely on the nurse's personal experience and manual operation, making it difficult to guarantee the accuracy and consistency of the injection angle. This not only increases the workload of nurses but may also adversely affect the patient's treatment outcome. Therefore, there is an urgent need for a device that can assist in adjusting the injection angle to improve the accuracy and stability of injections, reduce the workload of nurses, and ensure the patient's treatment effect. Utility Model Content

[0004] The present invention aims to provide a device to assist syringe injection, so as to solve the problem that existing injections require full manual control of the injection angle and injection time, which is very tiring for medical staff.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a device for assisting syringe injection, comprising an angle adjustment device, the angle adjustment device comprising a skin patch, a rotating shaft at the front end of the skin patch, a support plate hinged to the skin patch via the rotating shaft, an arc-shaped adjustment plate fixedly connected to the top end of the skin patch, a sliding groove at the front end of the arc-shaped adjustment plate, a connecting column fixedly connected to the rear end of the support plate, a slider fixedly connected to the free end of the connecting column, the slider slidably connected within the sliding groove, a limit block fixedly connected to the top end of the support plate, L-shaped fixing blocks hinged to the left and right sides of the top end of the support plate, a connecting rope fixedly connected to the rear end of the skin patch, an injection control device fixedly connected to the free end of the connecting rope, the injection device comprising a device body, a locking block fixedly connected to the front end of the device body, a semi-circular hole penetrating the locking block and the front wall of the device body at the front end of the locking block, an electric push rod fixedly connected to the inner rear wall of the device body, a power supply, a controller, and a switch disposed within the device body, the electric push rod, power supply, switch, and controller being electrically connected.

[0006] Preferably, the front end of the skin patch has an arc-shaped notch.

[0007] Preferably, an adhesive layer is fixedly connected to the bottom end of the skin patch.

[0008] Preferably, the front end of the unit type adjustment panel is provided with an angle indicator.

[0009] Preferably, the top end of the support plate and the bottom end of the L-shaped fixing block are provided with anti-slip textures.

[0010] Preferably, the support plate has a groove at its rear end.

[0011] The principle and beneficial effects of this technical solution:

[0012] The principle and beneficial effects of this technical solution are as follows:

[0013] The angle adjustment device of this invention connects the skin patch to the support plate via a rotating shaft. A groove on the arc-shaped adjustment plate engages with a slider at the rear end of the support plate, allowing for flexible angle adjustment. Simultaneously, the design of the limiting block and L-shaped fixing block ensures the syringe is stably placed on the support plate, preventing shaking or angle deviation during injection. The injection control device, through electrical connections of an electric push rod, power supply, controller, and switch, achieves automated control of the injection process. Medical personnel only need to set the parameters before injection to accurately inject the medication within the specified time.

[0014] Traditional injection procedures require nurses to manually control the injection angle and time throughout the entire process. Prolonged focus and manual operation are not only physically demanding, but also prone to fatigue, leading to inaccurate control of the injection angle and time, which affects the treatment effect. The auxiliary regulator of this invention can accurately maintain the injection angle between 15 and 30 degrees, ensuring the stability and consistency of the injection process. At the same time, the automated injection control device avoids interference from human factors, improving the accuracy and safety of the injection. Attached Figure Description

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0018] Example:

[0019] like Figure 1 The illustrated device for assisting syringe injection includes an angle adjustment device and an injection control device. The angle adjustment device mainly consists of a skin patch 1, a support plate 2, and an arc-shaped adjustment plate 3, while the injection control device includes the device body 10 and a motorized push rod 13. These components work together to achieve precise adjustment of the injection angle and automated control of the injection process.

[0020] The angle adjustment device provides stable support for the syringe and ensures the accuracy of the injection angle. The skin patch 1 is the basic component of the entire device, connected to the support plate 2 via a pivot at its front end, allowing the support plate 2 to be angled around the pivot. To improve the stability and usability of the device, the front end of the skin patch 1 is designed with an arc-shaped notch 14. When the needle is inserted into the patient's body, the center of the arc-shaped notch precisely corresponds to the needle insertion position, thus ensuring accurate injection angle control. Furthermore, an adhesive layer is fixedly connected to the bottom of the skin patch 1, allowing the device to be directly adhered to the patient's skin, ensuring that the device does not shift during injection.

[0021] The device can be used multiple times, but replacing the adhesive layer is relatively troublesome. Alternatively, a fixing plate can be fixedly connected to both sides of the skin patch 1 as an alternative solution. The plate can be attached to the patient's skin and the fixing plate with medical tape, which can also achieve a stable fixation effect.

[0022] The curved adjustment plate 3 is fixedly connected to the top of the skin patch 1, and its front end has a groove 4. The design of the groove 4 is key to achieving angle adjustment. A connecting post 5 is fixedly connected to the rear end of the support plate 2, and a slider is fixedly connected to the free end of the connecting post 5. The slider is slidably connected within the groove 4. By sliding the slider within the groove 4, the angle of the support plate 2 can be adjusted to meet the angle requirements under different injection needs. To further ensure the accuracy of the injection angle, an angle indicator is also provided at the front end of the curved adjustment plate 3. Medical personnel can intuitively adjust and confirm the injection angle according to the angle indicator to ensure that it is within the range of 15 to 30 degrees, which meets the strict requirements for dual-target injection of breast cancer patients.

[0023] A limiting block 7 is fixedly connected to the top of the support plate 2. The function of the limiting block 7 is to prevent the syringe from shifting or deviating in angle during injection. L-shaped fixing blocks 8 are hinged to both the left and right sides of the top of the support plate 2. The design of the L-shaped fixing blocks 8 can firmly clamp the syringe needle handle, ensuring that the angle between the syringe and the support plate 2 remains consistent. In addition, a tube groove 6 is provided at the rear end of the support plate 2, through which the extension tube at the rear end of the syringe can pass, preventing the extension tube from being bent during injection and ensuring that the medication can smoothly enter the patient's body.

[0024] There is significant resistance between the slider and the groove, as well as between the L-shaped fixed block. Locking devices can be installed at these two locations to ensure that the block is not easily moved without human intervention.

[0025] The function of the injection control device is to automate the injection process. The injection control device is connected to the rear end of the skin patch 1 via a connecting rope 9. The free end of the connecting rope 9 is fixedly connected to the device body 10. The two devices are usually used together, and the connecting rope 9 ensures that the devices can be easily found together, preventing loss. A locking block 11 is fixedly connected to the front end of the device body 10. The front end of the locking block 11 has a semi-circular hole 12 that passes through the locking block and the front wall of the device body. Before injection, the pressing part at the tip of the syringe needle is placed inside the locking block 11. At this time, the piston rod of the syringe is placed inside the device body 10, causing the push rod of the electric push rod 13 to abut against the pressing part at the tip of the piston rod.

[0026] An electric plunger 13 is fixedly connected to the rear wall inside the device body 10. The electric plunger 13 is electrically connected to the circuit system inside the device body 10 via a power supply, controller, and switch. During injection, medical personnel can set the injection time and speed as needed, and the controller will control the movement of the electric plunger 13 according to the set parameters. The electric plunger 13 completely squeezes the medication out of the syringe within the specified time, thus achieving automated control of the injection process. This automated control method not only improves the accuracy and stability of injection but also greatly reduces the workload of medical personnel, avoiding problems such as fatigue and injection angle deviation caused by holding the syringe for a long time.

[0027] The specific implementation process is as follows:

[0028] Medical personnel need to place the pressing part at the tip of the syringe needle into the locking block 11, ensuring that the piston rod of the needle is inside the device body 10, and that the push rod of the electric push rod 13 and the pressing hand at the tip of the piston rod are in contact. Then, insert the needle into the patient's body, ensuring that the needle insertion position is accurate. Attach the angle adjustment device to the patient's skin near the needle insertion position.

[0029] Adjust the angle of support plate 2 according to the injection requirements. The angle of support plate 2 can be adjusted by sliding the slider within the groove 4. Medical staff can visually adjust and confirm the injection angle based on the angle markings on the front end of the arc-shaped adjustment plate 3, ensuring it is within the range of 15 to 30 degrees.

[0030] The syringe needle handle is placed on top of the support plate 2, and the rear end of the needle handle is held in place by the limiting block 7 to prevent the syringe from being ejected during injection. Then, the needle handle is firmly clamped by the L-shaped fixing block 8 to ensure that the angle between the syringe and the support plate 2 remains consistent. At the same time, the extension tube at the rear end of the syringe can pass through the tube groove 6 at the rear end of the support plate 2 to prevent the extension tube from being bent during injection.

[0031] After completing the above preparations, medical staff can set the injection time and speed as needed. The controller will control the movement of the electric push rod 13 according to the set parameters. The electric push rod 13 will completely squeeze the liquid in the syringe within the specified time, thereby realizing the automated control of the injection process.

[0032] The above descriptions are merely embodiments of this utility model. Commonly known technical solutions or characteristics are not described in detail here. For those skilled in the art, various modifications and improvements can be made without departing from the technical solution of this utility model, and these should also be considered within the scope of protection of this utility model. These modifications will not affect the effectiveness of the implementation of this utility model or the practicality of the patent. The scope of protection claimed in this application shall be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
