[0001] The present invention relates to the field of medical devices, and particularly to an anti-inflammatory injector and device. Background Art

[0002] The gynecological anti-inflammatory injector is a medical device used for treating inflammation of the female reproductive system. It is mainly used to directly inject drugs into the cervix or vagina to achieve the effect of local treatment. By administering drugs in this way, the concentration of drugs at the lesion site can be increased, thereby enhancing the therapeutic effect and reducing systemic side effects.

[0003] The existing anti-inflammatory injectors cannot be fully and continuously lubricated during use, resulting in excessive friction during use, making it very uncomfortable during use and reducing the treatment quality. Summary of the Invention

[0004] The purpose of the present invention is to provide an anti-inflammatory injector and device, aiming to better provide lubrication during the insertion process, reduce the discomfort during insertion, and make the use more comfortable.

[0005] To achieve the above purpose, the present invention provides an anti-inflammatory injector, including a tube body, a first-stage piston rod, a pushing ring, a lubricating cavity, a flexible sleeve, a second-stage piston rod, a stopper, and a medicine tube. The medicine tube is arranged inside the tube body. The second-stage piston rod is slidably arranged inside the medicine tube. The flexible sleeve has a plurality of through holes and is sleeved outside the tube body. The lubricating cavity is arranged on one side of the tube body and is communicated with the flexible sleeve. The pushing ring is slidably arranged on one side of the lubricating cavity. The first-stage piston rod is slidably arranged on one side of the pushing ring and the second-stage piston rod. The stopper is used to control the on-off of the first-stage piston rod and the pushing ring.

[0006] Wherein, the aperture of the flexible sleeve gradually decreases from the medicine tube to the first-stage piston rod.

[0007] Wherein, the second-stage piston rod includes a piston rod body and a damping ring. The damping ring is fixedly connected to the piston rod body and is located between the piston rod body and the medicine tube.

[0008] Wherein, the stopper includes a connecting block, a spring piece, a pushing ring, and a push rod. The connecting block is slidably arranged on one side of the first-stage piston rod. The spring piece is arranged on one side of the connecting block. The pushing ring is slidably arranged on one side of the first-stage piston rod. One end of the push rod is rotatably connected to the pushing ring, and the other end of the push rod is rotatably connected to the connecting block.

[0009] Wherein, the pushing ring has a protrusion, and the protrusion is arranged on one side of the pushing ring.

[0010] Among them, the medicine tube includes a medicine tube body, a medicine spraying head, and a clamping ring. The medicine spraying head is communicated with the medicine tube body and passes through the tube body. The clamping ring is arranged on one side of the tube body, and a clamping groove is correspondingly arranged on the medicine spraying head for the clamping ring.

[0011] Among them, the anti-inflammatory injector further includes a sealing ring, and the sealing ring is arranged between the medicine tube body and the tube body.

[0012] Among them, the anti-inflammatory injector further includes an absorption sponge, and the absorption sponge is arranged on one side of the lubricating cavity for absorbing excess lubricating fluid.

[0013] In a second aspect, the present invention further provides an anti-inflammatory injection device, including an anti-inflammatory injector and a visual structure. The visual structure is arranged on one side of the tube body for observing the position of the patient.

[0014] For an anti-inflammatory injector and device of the present invention, the core of the entire device is the tube body, which serves as a carrier for other internal components and provides a closed space for the entire system. A medicine tube is arranged inside the tube body, and the medicine tube contains the medicine to be injected. The secondary piston rod slides inside the medicine tube, and the medicine is extruded from the medicine tube through its movement to achieve the injection of the medicine.

[0015] The flexible sleeve is an important part sleeved outside the tube body, and it is distributed with a plurality of through holes. The design of these through holes is to enable the lubricant to be evenly distributed on the surface of the flexible sleeve, thereby reducing the friction when contacting the skin and improving the comfort of the patient during use. The lubricating cavity is located on one side of the tube body and is communicated with the flexible sleeve, responsible for delivering the lubricant to the flexible sleeve to ensure the smoothness of the instrument during insertion or removal.

[0016] The pushing ring is installed on one side of the lubricating cavity and can slide along the lubricating cavity. When the pushing ring moves, it can squeeze the lubricant in the lubricating cavity, enabling it to enter the flexible sleeve through the connection, thereby achieving the lubrication effect. The primary piston rod is located between the pushing ring and the secondary piston rod. Its main function is to control the supply amount of the lubricant through the cooperation of the stopper and the pushing ring to ensure that the lubrication process is both efficient and not excessive. Then, after the tube body enters the expected position, the pushing ring and the primary piston rod are separated by the stopper. At this time, the primary piston rod can be pushed forward alone to contact the secondary piston rod, and further push the secondary piston rod to spray the medicine in the medicine tube to the target position, so as to better provide lubrication during the insertion process, reduce the discomfort during insertion, and make the use more comfortable.

In addition, in the description of the present invention, the meaning of "a plurality of" is two or more, unless otherwise specifically defined.

[0026] The first embodiment

[0027] Please refer to Figures 1 to 4 , the present invention provides an anti-inflammatory injector, which includes a tube body 101, a first-stage piston rod 102, a pushing ring 103, a lubricating cavity 104, a flexible sleeve 105, a second-stage piston rod 106, a stopper 107 and a medicine tube 108. The medicine tube 108 is arranged inside the tube body 101. The second-stage piston rod 106 is slidably arranged inside the medicine tube 108. The flexible sleeve 105 has a plurality of through holes 109. The flexible sleeve 105 is sleeved outside the tube body 101. The lubricating cavity 104 is arranged on one side of the tube body 101 and communicates with the flexible sleeve 105. The pushing ring 103 is slidably arranged on one side of the lubricating cavity 104. The first-stage piston rod 102 is slidably arranged on one side of the pushing ring 103 and the second-stage piston rod 106. The stopper 107 is used to control the on-off of the first-stage piston rod 102 and the pushing ring 103.

[0028] In this embodiment, the core of the entire device is the tube body 101. It serves as a carrier for other internal components and provides a closed space for the entire system. The medicine tube 108 is arranged inside the tube body 101, and the medicine tube 108 contains the medicine to be injected. The second-stage piston rod 106 slides inside the medicine tube 108, and the medicine is extruded from the medicine tube 108 through its movement to achieve the injection of the medicine.

[0029] The flexible sleeve 105 is an important part sleeved outside the tube body 101, and it is distributed with a plurality of through holes 109. The design of these through holes 109 is to enable the lubricant to be evenly distributed on the surface of the flexible sleeve 105, thereby reducing the frictional force when contacting the skin and improving the comfort of the patient during use. The lubricating cavity 104 is located on one side of the tube body 101 and is connected to the flexible sleeve 105, responsible for delivering the lubricant to the flexible sleeve 105 and ensuring the smoothness of the instrument during insertion or removal.

[0030] The push ring 103 is installed on one side of the lubrication cavity 104 and can slide along the lubrication cavity 104. When the push ring 103 moves, it can squeeze the lubricant in the lubrication cavity 104, enabling it to enter the flexible sleeve 105 through the connection, thereby achieving the lubrication effect. The first-stage piston rod 102 is located between the push ring 103 and the second-stage piston rod 106. Its main function is to control the supply amount of the lubricant through the cooperation of the stopper 107 and the push ring 103, ensuring that the lubrication process is both efficient and not excessive. Then, after the tube body 101 enters the expected position, the push ring 103 and the first-stage piston rod 102 are separated by the stopper 107. At this time, the first-stage piston rod 102 can be pushed forward alone to contact the second-stage piston rod 106, and further push the second-stage piston rod 106 to eject the drug in the drug tube 108 to the target position, so as to better provide lubrication during the insertion process, reduce the discomfort during insertion, and make the use more comfortable.

[0031] The aperture diameter on the flexible sleeve 105 gradually decreases from the drug tube 108 to the first-stage piston rod 102.

[0032] Due to the change in the aperture diameter, the flow rate of the lubricant inside the flexible sleeve 105 will be adjusted accordingly, ensuring that the lubricant can be more concentratedly distributed where it is needed, effectively reducing the waste of the lubricant, and improving the lubrication effect. Such a design is particularly important for reducing the friction between the instrument and the tissue and improving the patient's comfort.

[0033] The second-stage piston rod 106 includes a piston rod body 110 and a damping ring 111. The damping ring 111 is fixedly connected to the piston rod body 110 and is located between the piston rod body 110 and the drug tube 108.

[0034] The damping ring 111 is fixedly connected to the piston rod body 110 and is located between the piston rod body 110 and the drug tube 108. The main function of the damping ring 111 is to provide a certain resistance to control the outflow speed of the drug from the drug tube 108, avoiding the rapid ejection of the drug due to excessive pressure, which affects the accuracy and safety of drug administration. In addition, the damping ring 111 can also help maintain the stable state of the second-stage piston rod 106 inside the drug tube 108, reducing the possible shaking or deviation during drug administration.

[0035] The stopper 107 includes a connecting block 112, a spring piece 113, a push ring 114, and a push rod 115. The connecting block 112 is slidably arranged on one side of the first-stage piston rod 102. The spring piece 113 is arranged on one side of the connecting block 112. The push ring 114 is slidably arranged on one side of the first-stage piston rod 102. One end of the push rod 115 is rotatably connected to the push ring 114, and the other end of the push rod 115 is rotatably connected to the connecting block 112.

[0036] The connecting block 112 is slidably arranged on one side of the first-stage piston rod 102 and can slide along the first-stage piston rod 102 as required. The elastic sheet 113 is arranged on one side of the connecting block 112, providing the necessary elastic restoring force so that the stopper 107 can automatically reset and maintain a good working state. The push ring 114 is also slidably arranged on one side of the first-stage piston rod 102 and works in cooperation with the connecting block 112. During operation, the push ring 114 is pushed to drive the push rod 115 to push the connecting block 112, so that the connecting block 112 disengages from the push ring 103, enabling the first-stage piston rod 102 to operate independently.

[0037] The push ring 114 has a protrusion 116, and the protrusion 116 is arranged on one side of the push ring 114.

[0038] The push ring 114 is provided with a protrusion 116 on one side, which can increase the friction with the human hand, making it more convenient to push the push ring 114.

[0039] The medicine tube 108 includes a medicine tube body 117, a medicine spraying head 118 and a clamping ring 119. The medicine spraying head 118 is communicated with the medicine tube body 117 and passes through the tube body 101. The clamping ring 119 is arranged on one side of the tube body 101, and a clamping groove is correspondingly arranged on the medicine spraying head 118 for the clamping ring 119.

[0040] The medicine tube body 117 is the main part of the medicine tube 108 and is responsible for accommodating the medicine to be injected. The medicine tube body 117 is usually made of biocompatible materials to ensure that it will not chemically react with the medicine and can also ensure its safe use in the human body.

[0041] The medicine spraying head 118 is communicated with the medicine tube body 117, passes through the tube body 101, and directly contacts the injection site of the patient. The medicine spraying head 118 has a certain taper to make it easier to penetrate the skin or tissue and reduce the discomfort of the patient. Tiny holes may also be designed at the tip of the medicine spraying head 118 to ensure that the medicine can be evenly distributed. The clamping ring 119 is arranged on one side of the tube body 101 to fix the position of the medicine tube 108. A clamping groove is arranged on the medicine spraying head 118 corresponding to the clamping ring 119. After the medicine spraying head 118 is inserted into the tube body 101, the clamping ring 119 will snap into the clamping groove to ensure that the medicine tube 108 will not loosen or fall off during use, thus ensuring the stability of the drug administration process.

[0042] The anti-inflammatory injector further includes a sealing ring 120, and the sealing ring 120 is arranged between the medicine tube body 117 and the tube body 101.

[0043] To further improve the sealing performance of the anti-inflammatory injector and prevent drug leakage or entry of external contaminants, the injector further includes a sealing ring 120. The sealing ring 120 is disposed between the medicine tube body 117 and the tube body 101 and is usually made of an elastic material such as silicone or rubber. When the medicine tube body 117 is inserted into the tube body 101, the sealing ring 120 will be compressed to form a tight sealing layer, effectively isolating the internal and external environments and ensuring the purity and safety of the drug during transmission.

[0044] To handle the excess lubricating fluid that may be generated during the lubrication process, the anti-inflammatory injector is also equipped with an absorption sponge 121. The absorption sponge 121 is disposed on one side of the lubrication cavity 104, and its main function is to absorb and store the excess lubricating fluid. This can not only prevent the lubricating fluid from overflowing and contaminating the surgical area, but also keep the surface of the instrument clean and dry, improving the convenience and safety of the operation.

[0045] Through the above design, the anti-inflammatory injector can not only ensure the accurate delivery of the drug, but also greatly improve the safety and comfort of use. Specifically:

[0046] The combined design of the medicine tube body 117, the medicine application nozzle 118, and the snap ring 119 ensures that the drug can be accurately delivered to the target position, avoiding problems such as drug waste or inaccurate dosage.

[0047] The use of the sealing ring 120 effectively prevents drug leakage and also avoids the intrusion of external contaminants, ensuring the purity of the drug.

[0048] The design of the absorption sponge 121 solves the problem of excess lubricating fluid that may be generated during the lubrication process, keeps the surgical area clean and tidy, and improves the convenience of the operation.
