[0002] Cryotherapy drug delivery devices that reduce radiation-induced mucosal damage are commonly used in cancer patients after radiotherapy to care for mucosal damage in areas such as the mouth, throat, esophagus, and rectum. Their core function is to relieve mucosal redness, swelling, and pain through low-temperature cryotherapy, while precisely delivering repair drugs to reduce inflammatory responses, promote mucosal healing, and minimize the impact of radiotherapy-related mucosal damage on patients' eating and quality of life, thus facilitating the smooth progress of radiotherapy.

[0003] In practical applications, existing cryotherapy drug delivery devices for reducing radiation-induced mucosal damage, using cryotherapy modules in conjunction with drug delivery components, can meet the basic need for relieving mucosal redness and swelling. However, the following issues still exist: Common cryotherapy drug delivery devices for reducing radiation-induced mucosal damage typically use a snap-fit ​​structure, requiring tools for opening and closing. Furthermore, the complex structure of the connection between the tube and the device leads to drug and medium residues during routine cleaning and maintenance, affecting the effectiveness of the treatment. Therefore, this application provides a cryotherapy drug delivery device for reducing radiation-induced mucosal damage to meet this need. Summary of the Invention

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] like Figure 1 - Figure 7 As shown, this embodiment provides a technical solution: a cryotherapy drug delivery device for reducing radiation-induced mucosal damage, including a cryotherapy device body 1 and a control component 11 disposed on the side of the cryotherapy device body 1. A connecting tube 12 is disposed on the side of the control component 11. The device also includes: The protective component 2 includes a knob 21 disposed on the outer surface of the connecting pipe 12, a connector 22 connected to the side of the knob 21, a first support plate 23 connected to one end of the connector 22, a first slide rod 25 disposed on the side of the first support plate 23, and a first sealing plate 26 connected to one end of the first slide rod 25. The quick-connect component 3 includes a sleeve 32 disposed in the inner cavity of the cryotherapy device body 1, and a sealing gasket 34 is disposed in the inner cavity of the sleeve 32. Auxiliary component 4 includes a protective shell 45 connected to the side of the cryotherapy device body 1, with a collar 43 connected to one end of the protective shell 45. A guide groove 24 is provided on the side of the first support plate 23. A second slide rod 29 is connected to the end of the first sealing plate 26 away from the first slide rod 25. A second support plate 27 is also provided on the outer surface of the connecting tube 12, with a first slide groove 28 provided on its side. A second sealing plate 210 is connected to the inner cavity of the connecting tube 12. A storage box is provided in the inner cavity of the cryotherapy device body 1 to provide storage space for the condensation medium. A knob 21 allows for convenient manual adjustment of the rotation angle of the connecting member 22. By rotating the connecting member 22 connected to the outer surface of the connecting tube 12, the rotation angle can be adjusted. The rotational force is transmitted to the first support plate 23. In use, the first support plate 23 can be manually rotated clockwise, thereby driving the first slide rod 25 to move horizontally through the guide groove 24, which in turn drives the first sealing plate 26 to open and close, achieving rapid adjustment. During the use of the first sealing plate 26, the movement trajectory of the first sealing plate 26 can be limited by the cooperation of the first slide groove 28 and the second slide rod 29. The second sealing plate 210, which is fixedly connected to the inner wall of the connecting pipe 12, can cooperate with the first sealing plate 26 to close and protect the inner cavity of the pipe, improving the sealing effect. The second support plate 27, which is fixedly connected to the outer surface of the connecting pipe 12, can provide support for the second slide rod 29.

[0017] Furthermore, such as Figure 3 , Figure 5 and Figure 7 As shown: The inner wall of the sleeve 32 has a second sliding groove 33; the side of the connecting pipe 12 is connected to a protrusion 31; the side of the sealing gasket 34 is connected to an elastic gasket 35; a sealing ring 36 is provided at one end of the sleeve 32; the side of the sealing ring 36 is fixedly connected to one end of the connecting pipe 12; the sealing gasket 34 is made of EPDM rubber, which can maintain elasticity for a long time and ensure the reliability of the seal; the elastic gasket 35 is made of foam material with a closed-cell structure, which is used to prevent liquid from seeping into the foam cells and causing contamination or freeze-thaw damage; the sealing ring 36 is made of PTFE, which can... To ensure smooth rotation while reducing wear and effectively extending service life, when the connecting pipe 12 needs to be disassembled and cleaned, first push the connecting pipe 12, which will cause the protrusion 31 to move along the inner cavity of the second slide groove 33 towards the end close to the sealing gasket 34. At this time, rotate the connecting pipe 12 clockwise, which will cause the protrusion 31 to disengage from the inner cavity of the second slide groove 33, thereby disconnecting the connecting pipe 12 from the sleeve 32. During the use of the connecting pipe 12, the sealing gasket 34, the elastic gasket 35 and the sealing ring 36 work together to provide sealing protection at the connection.

[0018] Furthermore, such as Figure 6As shown: In this design, the inner wall of the collar 43 has a groove 44, and the inner cavity of the groove 44 is provided with a snap-fit ​​block 41. The bottom of the snap-fit ​​block 41 is connected to a mounting bracket 42. The protective shell 45 is provided with a mounting bracket at one end near the connecting tube 12. The bracket works with the screw rod for fixed installation. In use, first push the connecting tube 12 into the inner cavity of the sleeve 32. After the connecting tube 12 is snapped and fixed to the inner cavity of the sleeve 32, the protective shell 45 is fixedly connected to the outer surface of the connecting tube 12 by the screw rod to provide stable support for the collar 43. When the knob 21 controls the closed state of the first sealing plate 26, it can synchronously drive the snap-fit ​​block 41 and the mounting bracket 42 to rotate. By designing the shape of the groove 44 to match the shape of the snap-fit ​​block 41, it can provide a limit for the snap-fit ​​block 41. The snap-fit ​​block 41 is made of polyetheretherketone (PEEK) to withstand the repeated meshing motion between the snap-fit ​​block 41 and the collar 43, reduce the wear caused by separation, and maintain good elastic recovery ability under frequent cyclic force, and is not prone to permanent deformation.

[0019] Working principle: like Figure 1-7 As shown: In use: First, the operator manually pushes the connecting pipe 12 into the inner cavity of the sleeve 32, causing the protrusion 31 to rotate counterclockwise along the inner cavity of the second groove 33. When the protrusion 31 moves to a certain position, the side of the sealing ring 36 contacts the side of the sealing gasket 34, causing the elastic gasket 35 to compress. Through the cooperation of the sealing gasket 34, the elastic gasket 35, and the sealing ring 36, a certain reverse limiting stress is provided to the sealing ring 36 while providing sealing protection at the connection between the connecting pipe 12 and the sleeve 32. After the connecting pipe 12 and the sleeve 32 are engaged, the protective shell 45 is fixed to the outer surface of the connecting pipe 12 by the screw rod. Then, the external pipeline is connected to the connecting pipe 12, thereby enabling... The condensing medium inside the body 1 of the cryotherapy device is delivered to the damaged mucosa of the patient. When the body 1 of the cryotherapy device needs to be temporarily stored away for the next cryotherapy session, the knob 21 is manually rotated clockwise, which causes the connector 22 to drive the first support plate 23 to rotate along the outer surface of the connecting tube 12. Through the cooperation of the guide groove 24 and the first slide rod 25, the first sealing plate 26 is closed, thereby quickly sealing the inner cavity of the connecting tube 12 and achieving sealing protection for the condensing medium inside the body 1 of the cryotherapy device. Similarly, when a second cryotherapy session is required, the knob 21 is rotated counterclockwise, which causes the first sealing plate 26 to be released from its closed state, effectively improving the efficiency of use and ensuring the effect of cryotherapy.

[0020] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
