Description

Technical Field

[0001] This invention relates to the medical field, and more particularly to a drug delivery injection needle for skin infections. Background Technology

[0002] Drug delivery needles are medical devices used to deliver drugs directly into the body. These devices are widely used in the medical field to treat, diagnose, or prevent diseases. In the medical field, drug injection is a common and effective treatment for skin infections.

[0003] In existing drug injection procedures, multiple drugs usually need to be manually mixed before injection to ensure drug efficacy and therapeutic effect. However, the manual mixing process is cumbersome and time-consuming, and it is not convenient to directly mix and deliver the drugs into the syringe.

[0004] Therefore, there is a need to design a convenient drug delivery needle for skin infections that can mix and deliver drugs into a syringe without the need for manual mixing. Summary of the Invention

[0005] To overcome the shortcomings of existing drug injection processes, which involve cumbersome and time-consuming manual mixing, making it impossible to directly mix and deliver the drug into the syringe and thus inconvenient to use, this invention provides a convenient drug delivery needle for skin infections that can mix and deliver the drug into the syringe without the need for additional manual mixing.

[0006] The technical implementation of the present invention is as follows: a drug delivery injection needle for skin infections includes an injection cylinder, an injection needle, a connecting sleeve, a squeezing rod, a squeezing plug, a spring, and a delivery and mixing assembly. The lower part of the injection cylinder is threadedly connected to the connecting sleeve, and the injection needle is connected to the connecting sleeve. The upper part of the injection cylinder is threadedly provided with a cap, and the squeezing rod is slidably connected to the cap. The squeezing plug is connected to the lower side of the squeezing rod, and a spring is connected between the squeezing rod and the cap. The upper part of the injection cylinder is provided with a delivery and mixing assembly capable of mixing and delivering drugs.

[0007] Furthermore, the connecting sleeve is equipped with anti-slip texture.

[0008] Furthermore, the conveying and mixing assembly includes a conveying pipe, a spiral vane, and a motor. The upper right side of the injection cylinder is connected to the conveying pipe, the right side of the conveying pipe is connected to the motor, and the spiral vane is connected to the motor output shaft.

[0009] Furthermore, it also includes graduation lines, with graduation lines located on the outside of the syringe.

[0010] Furthermore, it also includes a gasket, with a gasket connected to the lower side of the squeeze plug.

[0011] Furthermore, the gasket is made of rubber.

[0012] Furthermore, it also includes a drug inlet, which is connected to the upper right side of the delivery tube.

[0013] Furthermore, the drug infusion nozzle has a funnel-shaped structure.

[0014] The present invention has the following advantages: 1. The present invention starts the motor to drive the spiral blade to rotate, so that the drug in the delivery tube moves towards the injection cylinder. At the same time, the spiral blade mixes the drug, so that the mixed drug is injected into the injection cylinder. This achieves the effect of mixing and delivering the drug into the injection cylinder without the need for manual mixing, which is convenient to use.

[0015] 2. This invention involves inserting an injection needle into the infected skin area, then slowly releasing the squeezing rod. The spring gradually returns to its original state, causing the squeezing rod and the pad to move downwards, allowing the medication to be discharged through the injection needle. This achieves a slow delivery of the medication, avoiding excessive force that could cause discomfort, while ensuring slow drug release and prolonging the therapeutic effect.

[0016] 3. This invention opens the cap by rotating it, and then rotates the connecting sleeve 31, causing the connecting sleeve 31 to move downwards and disengage from the injection cylinder 1 under the action of the threads. This allows for cleaning of the injection cylinder 1 and also enables the replacement of the injection needle. Single or multiple needles can be used as needed, and when switching to multiple needles, uniform drug distribution is achieved. Attached Figure Description

[0028] References to embodiments herein mean that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0029] A drug delivery needle for skin infections, such as Figures 1-10 As shown, the device includes a syringe 1, a scale line 2, an injection needle 3, a connecting sleeve 31, a squeezing rod 4, a squeezing plug 5, a gasket 51, a spring 6, and a mixing and conveying assembly. The syringe 1 has a scale line 2 on its outer side. The lower part of the syringe 1 is threadedly connected to the connecting sleeve 31, which has anti-slip textures for easy gripping. The injection needle 3 is connected to the connecting sleeve 31. The upper part of the syringe 1 has a threaded cap, on which the squeezing rod 4 is slidably connected. The squeezing plug 5 is connected to the lower side of the squeezing rod 4. A gasket 51 is connected to the side. The gasket 51 is made of rubber. A spring 6 is connected between the extrusion rod 4 and the cap. The upper part of the syringe 1 is equipped with a conveying and mixing assembly, which includes a conveying pipe 7, a spiral blade 8, a motor 9, and a drug inlet 10. The upper right side of the syringe 1 is connected to the conveying pipe 7. The right side of the conveying pipe 7 is connected to the motor 9. The spiral blade 8 is connected to the output shaft of the motor 9. The upper right side of the conveying pipe 7 is connected to the drug inlet 10. The drug inlet 10 has a funnel-shaped structure for easy injection.

[0030] When using this invention, first, inject the medication to be injected into the medication inlet 10, allowing the medication to enter the delivery tube 7. Then, move the squeeze rod 4 upwards, stretching the spring 6. Next, start the motor 9, driving the spiral vane 8 to rotate, causing the medication in the delivery tube 7 to move towards the syringe 1. Simultaneously, the spiral vane 8 mixes the medication, allowing the mixed medication to be injected into the syringe 1. The amount of medication can be observed through the scale 2, thus enabling the medication to be mixed and delivered into the syringe 1 without the need for manual mixing, making it convenient to use. Afterward, insert the injection needle 3 into the infected skin area, and then slowly release the squeeze rod. As the pressure rod 4 and spring 6 gradually return to their original positions, the squeezing rod 4 and the gasket 51 move downwards, allowing the medication to be discharged through the injection needle 3. This slow delivery of the medication avoids excessive force that could cause discomfort and ensures a slow release of the medication, thus prolonging the therapeutic effect. When the syringe 1 needs to be cleaned, the cap can be rotated to open it, and then the connecting sleeve 31 can be rotated to move downwards and disengage from the syringe 1 under the action of the threads. The syringe 1 can then be cleaned. The injection needle can also be replaced at the same time, allowing for the replacement of a single needle or multiple needles as needed. When switching to multiple needles, the medication can be evenly distributed.

[0031] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
