Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0026] Please refer to Figure 1-6 , the present invention provides a technical solution: a chemotherapy pump structure for oncology, including a chemotherapy pump body 1. A sealing block 2 is provided on the outer wall of the chemotherapy pump body 1. A sealing mechanism 3 is provided inside the sealing block 2. An infusion tube 4 is installed on the outer wall of the sealing block 2. A fixing mechanism 5 is provided on the outer wall of the infusion tube 4. A placement mechanism 6 is provided on the outer wall of the chemotherapy pump body 1;
[0027] The sealing mechanism 3 includes a first fixing plate 31, a sealing ring 32, a second fixing plate 33, a limiting plate 34, a third fixing plate 35, a bolt 36 and a fourth fixing plate 37. A first fixing plate 31 is provided on the inner wall of the sealing block 2. A sealing ring 32 is installed on the inner wall of the first fixing plate 31. A second fixing plate 33 is provided on the inner wall of the sealing block 2. A limiting plate 34 is provided on the inner wall of the sealing block 2. A third fixing plate 35 is installed on the inner wall of the limiting plate 34. A bolt 36 is threadedly connected to the bottom wall of the third fixing plate 35. A fourth fixing plate 37 is installed on the outer wall of the third fixing plate 35. Through the settings of the first fixing plate 31, the sealing ring 32, the second fixing plate 33, the limiting plate 34, the third fixing plate 35, the bolt 36 and the fourth fixing plate 37, during use, the user needs to accurately insert the infusion tube 4 on the chemotherapy pump body 1 into the corresponding position of the sealing block 2. To ensure the stability and safety of the infusion tube 4, the coordinated work of these components not only accurately limits and firmly fixes the infusion tube 4, but also greatly enhances the sealing effect between the infusion tube 4 and the sealing block 2 through the ingenious setting of the sealing ring 32. In this way, it effectively avoids the leakage of the liquid medicine from the tiny gap between the infusion tube 4 and the sealing block 2, thereby preventing the occurrence of medical pollution.
[0028] Further, the fixing mechanism 5 includes an arm strap 51, a fixing strap 52, a hook-and-loop fastener female part 53, a fixing buckle 54 and a hook-and-loop fastener male part 55. An arm strap 51 is provided on the outer wall of the infusion tube 4. A fixing strap 52 is provided on the outer wall of the arm strap 51. A hook-and-loop fastener female part 53 is provided on the outer side wall of the fixing strap 52. A fixing buckle 54 is installed outside the fixing strap 52. A hook-and-loop fastener male part 55 is provided on the outer side wall of the fixing strap 52. Through the settings of the arm strap 51, the fixing strap 52, the hook-and-loop fastener female part 53, the fixing buckle 54 and the hook-and-loop fastener male part 55, when fixing, first the patient puts the arm into the arm strap 51, and then the arm strap 51 is fixed on the patient's arm through the fixing strap 52. Rotate the fixing strap 52, and the hook-and-loop fastener female part 53 and the hook-and-loop fastener male part 55 on the fixing strap 52 cooperate with each other, and the tightness of the fixing strap 52 can be easily adjusted to ensure that the infusion tube 4 is stably fixed on the patient's arm. At the same time, the design of the fixing buckle 54 makes the fixing strap 52 more firm and not easy to slip. In this way, even when the patient is moving, the infusion tube 4 will not cause the needle to fall off or the liquid medicine to leak due to displacement, greatly improving the comfort and safety of the patient.
[0029] Further, the placing mechanism 6 includes a fixing frame 61, a hanging ring 62, a rotating shaft 63, a clamping block 64, a hook 65 and a fixing block 66. A fixing frame 61 is provided on the outer wall of the chemotherapy pump body 1. A hanging ring 62 is provided on the outer wall of the chemotherapy pump body 1. A rotating shaft 63 is provided on the inner wall of the hanging ring 62. A clamping block 64 is provided on the outer side wall of the rotating shaft 63. A hook 65 is provided on the outer side wall of the fixing frame 61. A fixing block 66 is installed on the outer wall of the hook 65. Through the settings of the fixing frame 61, the hanging ring 62, the rotating shaft 63, the clamping block 64, the hook 65 and the fixing block 66, when the user uses the chemotherapy pump, the position of the chemotherapy pump body 1 can be flexibly adjusted according to the user's own needs and comfort. Specifically, the cooperation between the hanging ring 62 and the rotating shaft 63 enables the chemotherapy pump body 1 to rotate within a certain range, facilitating the user to find the most suitable carrying angle for himself. The design of the clamping block 64 further enhances the stability of the hanging ring 62 and prevents it from accidentally falling off during the rotation process. At the same time, the fixing frame 61 provides a stable support platform for the chemotherapy pump body 1, and the cooperation between the hook 65 and the fixing block 66 enables the user to easily hang the chemotherapy pump body 1 on the hospital bed, wheelchair or other suitable fixed objects, greatly reducing the user's carrying burden. In addition, this design also facilitates patients of different body types to make personalized adjustments according to their actual situations, making the use of the chemotherapy pump more comfortable and convenient.
[0030] Furthermore, multiple sets of sealing rings 32 are provided, and the sealing rings 32 are respectively installed on the outer side walls of the first fixing plate 31, the second fixing plate 33, the third fixing plate 35, and the fourth fixing plate 37. Through the setting of the sealing rings 32, the sealing performance between the infusion tube 4 and the sealing block 2 is further enhanced. The coordinated action of multiple sets of sealing rings 32 makes the sealing effect more reliable. Even during long-term use, it can effectively prevent the leakage of the liquid medicine, ensure the stable infusion of the chemotherapy drug, and at the same time reduce the risk of medical pollution.
[0031] Furthermore, the third fixing plate 35 is fixedly installed on the fourth fixing plate 37 through bolts 36, and the fourth fixing plate 37 is fixedly installed on the inner wall of the limiting plate 34 through bolts 36. Through the setting of the bolts 36, not only the firm connection between the third fixing plate 35 and the fourth fixing plate 37 is realized, but also the stable installation between the fourth fixing plate 37 and the limiting plate 34 is ensured. This design makes the entire sealing mechanism 3 more stable, capable of withstanding greater pressure, thereby further improving the sealing performance of the chemotherapy pump structure.
[0032] Furthermore, the outer wall size of the sealing ring 32 matches the inner wall size of the first fixing plate 31, and the outer wall size of the first fixing plate 31 matches the inner wall size of the sealing block 2. Through the setting of the first fixing plate 31, it is ensured that the sealing ring 32 can closely fit inside the sealing block 2, avoiding the leakage of the liquid medicine from the gap. At the same time, the tight fit between the first fixing plate 31 and the sealing block 2 further enhances the stability and reliability of the entire sealing structure.
[0033] Furthermore, the magic mother sticker 53 and the magic son sticker 55 form a detachable fixing structure, and the outer side wall of the fixing belt 52 is closely attached to the outer side wall of the arm strap 51. Through the setting of the arm strap 51, not only can the fixing mechanism 5 be firmly fixed on the patient's arm, ensuring the tight fit between the fixing belt 52 and the arm strap 51, but also avoiding the leakage of the liquid medicine or the displacement of the needle due to loose fixing.
[0034] Furthermore, the rotating shaft 63 and the clamping block 64 form a rotating structure, and two hooks 65 are provided, and they are symmetrically arranged with respect to the width central axis of the chemotherapy pump body 1. Through the setting of the rotating shaft 63, the chemotherapy pump body 1 can be adjusted more flexibly in angle to meet the user's usage requirements in different scenarios. The design of the clamping block 64 ensures the stability of the chemotherapy pump body 1 during the rotation process, preventing it from accidentally rotating due to external forces, thereby ensuring the safety of use.
[0035] Furthermore, the inner wall size of the hanging loop 62 matches the outer wall size of the rotating shaft 63, and the outer wall size of the chemotherapy pump body 1 matches the inner wall size of the fixing frame 61. Through the setting of the hanging loop 62, the chemotherapy pump body 1 can be stably hung on the fixing frame 61, avoiding accidental detachment or damage caused by shaking.
[0036] Working principle: During use, first, the user fixes the chemotherapy pump body 1 in a suitable position, such as on a hospital bed, wheelchair or other fixed object, through the placement mechanism 6. Then, the infusion tube 4 is accurately inserted into the corresponding position of the sealing block 2. At this time, each component in the sealing mechanism 3 starts to function, precisely limiting and firmly fixing the infusion tube 4. At the same time, the setting of the sealing ring 32 greatly enhances the sealing effect between the infusion tube 4 and the sealing block 2, effectively avoiding the leakage of the liquid medicine and preventing the occurrence of medical pollution. Then, the patient puts the arm into the arm strap 51, and through the mutual cooperation of the fixing belt 52, the magic mother sticker 53, the fixing buckle 54 and the magic son sticker 55 in the fixing mechanism 5, the infusion tube 4 is stably fixed on the patient's arm, ensuring that even during the patient's movement, the infusion tube 4 will not cause the needle to fall off or the liquid medicine to leak due to displacement. In addition, the user can also flexibly adjust the position and angle of the chemotherapy pump body 1 according to their own needs and comfort through the cooperation of the hanging loop 62 and the rotating shaft 63 in the placement mechanism 6, making the use of the chemotherapy pump more comfortable and convenient. The design of the entire chemotherapy pump structure fully considers the actual needs and comfort of the patient. Through the coordinated work of each mechanism, it not only improves the stability and safety of the chemotherapy pump, but also greatly reduces the carrying burden of the patient, making the chemotherapy process smoother and more comfortable.
[0037] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
