[0026] First embodiment

[0027] See also Figure 1 to Figure 4 The present invention provides an anti-inflammatory injector, comprising a tube body 101, a primary piston rod 102, a push ring 103, a lubricating cavity 104, a flexible sleeve 105, a secondary piston rod 106, a stopper 107 and a medicine tube 108, wherein the medicine tube 108 is arranged in the tube body 101, the secondary piston rod 106 is slidably arranged in the medicine tube 108, the flexible sleeve 105 has a plurality of through holes 109, the flexible sleeve 105 is sleeved on the outside of the tube body 101, the lubricating cavity 104 is arranged on one side of the tube body 101 and is communicated with the flexible sleeve 105, the push ring 103 is slidably arranged on one side of the lubricating cavity 104, the primary piston rod 102 is slidably arranged on one side of the push ring 103 and the secondary piston rod 106, and the stopper 107 is used to control the on-off of the primary piston rod 102 and the push ring 103.

[0028] In this embodiment, the core of the whole device is the tube body 101, which serves as a carrier of other components inside and provides a closed space for the whole system. A medicine tube 108 is arranged inside the tube body 101, and the medicine tube 108 contains the medicine to be injected, and the secondary piston rod 106 slides inside the medicine tube 108, and squeezes the medicine out of the medicine tube 108 through its movement to achieve the injection of the medicine.

[0029] The flexible sleeve 105 is an important component that is sleeved on the outside of the tube body 101, and is provided with a plurality of through holes 109. The through holes 109 are designed to allow the lubricant to be evenly distributed on the surface of the flexible sleeve 105, thereby reducing the friction when in contact with the skin and improving the comfort of the patient when using the device. The lubrication cavity 104 is located on one side of the tube body 101 and is connected to the flexible sleeve 105. It is responsible for delivering lubricant to the flexible sleeve 105, ensuring the smoothness of the device during insertion or removal.

[0030] The push ring 103 is installed on one side of the lubricating cavity 104 and can slide along the lubricating cavity 104. When the push ring 103 moves, it can squeeze the lubricant in the lubricating cavity 104 so that it enters the flexible sleeve 105 through the connection, thereby achieving the lubrication effect. The primary piston rod 102 is located between the push ring 103 and the secondary piston rod 106. Its main function is to control the supply amount of lubricant through the cooperation of the limiter 107 and the push ring 103 to ensure 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 primary piston rod 102 are separated by the limiter 107. At this time, the primary piston rod 102 can be pushed forward alone to contact the secondary piston rod 106, and further push the secondary piston rod 106 to spray the medicine in the medicine tube 108 to the target position, so that lubrication can be better provided during the entry process, reducing discomfort during insertion, and making it more comfortable to use.

[0031] The aperture of the flexible sleeve 105 gradually decreases from the medicine tube 108 to the primary piston rod 102 .

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

[0033] The secondary 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 medicine 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 medicine tube 108. The main function of the damping ring 111 is to provide a certain resistance to control the speed of the drug flowing out of the medicine tube 108, to avoid the drug from being ejected quickly due to excessive pressure, and to affect the accuracy and safety of drug administration. In addition, the damping ring 111 can also help maintain the stable state of the secondary piston rod 106 in the medicine tube 108, and reduce the shaking or deviation that may occur during the drug administration process.

[0035] The limiter 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 primary 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 primary 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 primary piston rod 102, and can slide along the primary piston rod 102 as required. The spring sheet 113 is arranged on one side of the connecting block 112, providing the necessary elastic restoring force, so that the limiter 107 can automatically reset and maintain a good working state. The push ring 114 is also slidably arranged on one side of the primary piston rod 102, and works in coordination with the connecting block 112. When working, the push ring 114 drives the push rod 115 to push the connecting block 112, so that the connecting block 112 is separated from the push ring 103, so that the primary piston rod 102 can operate independently.

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

[0038] A protrusion 116 is provided on the push ring 114 . The protrusion 116 is located on one side of the push ring 114 and can increase the friction with a person's hand, making it more convenient to push the push ring 114 .

[0039] The medicine tube 108 includes a medicine tube body 117, a medicine applying nozzle 118 and a retaining ring 119. The medicine applying nozzle 118 is connected to the medicine tube body 117 and passes through the tube body 101. The retaining ring 119 is arranged on one side of the tube body 101, and a retaining groove is arranged on the medicine applying nozzle 118 corresponding to the retaining ring 119.

[0040] The medicine tube body 117 is the main part of the medicine tube 108 and is responsible for containing 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 application nozzle 118 is connected to the medicine tube body 117, and passes through the tube body 101 to directly contact the patient's injection site. The medicine application nozzle 118 has a certain taper so that it is easier to penetrate the skin or tissue and reduce the patient's discomfort. The tip of the medicine application nozzle 118 may also be designed with tiny holes 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 provided on the medicine application nozzle 118 at a position corresponding to the clamping ring 119. When the medicine application nozzle 118 is inserted into the tube body 101, the clamping ring 119 will be clamped into the clamping groove to ensure that the medicine tube 108 will not loosen or fall off during use, thereby ensuring the stability of the drug administration process.

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

[0043] In order to further improve the sealing performance of the anti-inflammatory injector and prevent drug leakage or external contaminants from entering, the injector also includes a sealing ring 120. The sealing ring 120 is arranged between the medicine tube body 117 and the tube body 101, and is usually made of 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, which effectively isolates the internal and external environments and ensures the purity and safety of the drug during the transmission process.

[0044] In order to handle the excess lubricating fluid that may be generated during the lubrication process, the anti-inflammatory injector is also equipped with an absorbent sponge 121. The absorbent sponge 121 is arranged on one side of the lubrication cavity 104, and its main function is to absorb and store 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, thereby improving the convenience and safety of 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 spray nozzle 118 and the clamp ring 119 ensures that the medicine can be accurately delivered to the target location, avoiding the problem of medicine waste or inaccurate dosage.

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

[0048] The design of the absorbent 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 operation.

The display screen 125 is arranged on the support frame 124. The control module 126 has a second connector. The control module 126 is connected to the display screen 125. The second connector and the first connector are detachably connected.

[0052] The present invention provides an anti-inflammatory drug injection device, which not only includes the anti-inflammatory drug injection device mentioned above, but also adds a visual structure for real-time observation of the patient's position, thereby improving the accuracy and safety of drug administration. The following is a detailed design description of the device:

[0053] The endoscope 122 is used to observe the patient's position in real time to ensure that the drug can be accurately delivered to the target area. The endoscope 122 usually has a high-resolution camera and a light source, which can clearly display the image of the internal tissue. The endoscope 122 is connected to the wire 123 and is located on one side of the drug application nozzle 118. The purpose of this design is to enable the endoscope 122 to be close to the drug application nozzle 118 to ensure that the drug delivery can be observed in real time during the drug administration process.

[0054] The wire 123 is used to transmit the image signal and power source captured by the endoscope 122. One end (first connector) of the wire 123 is connected to the endoscope 122, and the other end is connected to the control module 126. The wire 123 is usually made of a flexible material to adapt to different operating environments and ensure that the flexibility of the endoscope 122 is not affected during use.

[0055] The support frame 124 is used to fix and support the display screen 125, ensuring that the display screen 125 remains stable during use. The support frame 124 is fixed to one side of the lubrication cavity 104, so that the design can make full use of the space and avoid interfering with the normal operation of other components.

[0056] The display screen 125 is used to display the real-time image captured by the endoscope 122, helping medical staff to accurately determine the location and effect of drug administration. The display screen 125 is arranged on the support frame 124, so that medical staff can view the image at any time during the operation.

[0057] The control module 126 is used to control the working state of the endoscope 122, including the acquisition, transmission and display of images. The control module 126 also has data storage and processing functions, and can record and analyze various parameters during the drug administration process. The control module 126 has a second connector, which is detachably connected to the first connector of the wire 123 through the second connector. This design allows the endoscope 122 and the control module 126 to be easily separated and assembled, and is convenient for maintenance and replacement.
