[0030] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0031] Example 1

[0032] like Figure 1 and Figure 2 As shown, this embodiment discloses a drug delivery device for tumor treatment that is easy to fix, including a telescopic bracket 1, a moving mechanism 2 at the lower end of the telescopic bracket 1, a plurality of hooks 7 at the upper end of the telescopic bracket 1, a fixing mechanism 4 at the middle of the outer surface of the telescopic bracket 1, and a support platform 3 at the middle of the outer surface of the fixing mechanism 4.

[0033] Specifically, the telescopic support 1, the moving mechanism 2, and the hook 7 together form a common infusion stand. Medical staff can hang the medicine bottle on the hook 7 and then introduce the medicine into the patient's body through the infusion tube. The telescopic support 1 can be extended and retracted to adjust the height of the medicine bottle hanging on the hook 7. The moving mechanism 2 consists of a cross and four silent wheels, which facilitates the movement of the infusion stand by the patient or medical staff. All of the above are existing technologies and will not be described in detail in this manual.

[0034] To support the support platform 3 so that it can support the patient's hand receiving the injection, such as... Figure 3 As shown, the fixing mechanism 4 includes a support tube 41, which is slidably installed on the outer surface of the telescopic bracket 1. A locking threaded rod 42 is provided at the lower end of the support tube 41, and a locking ring 43 is threadedly connected to the outer surface of the locking threaded rod 42.

[0035] Specifically, during the infusion process, patients are mostly sitting in a chair or lying in a hospital bed. However, when patients need to move, such as to go to the toilet, they need to stand up. Therefore, the height of the support platform 3 needs to be adjusted so that the patient can place their hand on the upper part of the support platform 3 for infusion.

[0036] Furthermore, when it is necessary to adjust the height of the support platform 3, the locking ring 43 can be turned so that the locking threaded rod 42 is no longer in close contact with the surface of the telescopic bracket 1. At this time, the support tube 41 can be pushed up and down, thereby causing the support tube 41 to drive the support platform 3 fixed on the support tube 41 to move up and down, thereby adjusting the height of the support platform 3. When the support platform 3 is adjusted to the corresponding height, the locking ring 43 is rotated in the opposite direction so that the locking ring 43 pushes the locking threaded rod 42 to contact the surface of the telescopic bracket 1 again. Through friction, the support tube 41 is fixed on the outer surface of the telescopic bracket 1, thereby fixing the support platform 3 at the corresponding height.

[0037] Furthermore, the locking threaded rod 42 and the clamping ring 43 together form a rotary locking mechanism, which is existing technology and will not be described in detail in this specification.

[0038] To support and stabilize the patient's hand during injection, such as... Figure 4 As shown, the support platform 3 includes a support plate 31, which is fixedly installed on the outer surface of the support tube 41. The upper end of the support plate 31 has two sliding grooves 32 on both sides, and the inner cavities of the two sliding grooves 32 are connected. Fixing members 34 are provided on both sides of the inner cavity of the two sliding grooves 32. A handrail 33 is provided in the middle of the lower end of the support plate 31, and the handrail 33 is fixedly installed on the lower part of the outer surface of the support tube 41.

[0039] Specifically, the patient can place the hand with the IV needle inserted on the upper end of the support plate 31, and then adjust the position of the fixation pieces 34 on both sides so that the fixation pieces 34 on both sides can fix the patient's hand.

[0040] Furthermore, during the adjustment of the height of the support platform 3, medical staff or patients can use the handrail 33 to move the support plate 31 and support tube 41 up and down.

[0041] To facilitate immobilization of the hands used for injecting medication into different patients, such as Figure 4 As shown, the fastener 34 includes a connecting plate 341, and sliders 343 are provided on both sides of the connecting plate 341. The connecting plate 341 and sliders 343 are slidably installed in the inner cavity of two slide grooves 32, and the upper end of the sliders 343 extends to the upper part of the slide grooves 32. Velcro 342 is provided on the upper part of the two sliders 343.

[0042] Specifically, during the adjustment of the position of the fixing member 34, pushing the slider 343 on one side can drive the slider 343 on the other side to move synchronously through the connecting plate 341.

[0043] Furthermore, after the fastener 34 is adjusted to the appropriate position, the patient's hand is fixed by the Velcro 342 on the two sliders 343.

[0044] In summary, the specific implementation method is as follows: the patient places their hand on the upper end of the support plate 31, and then adjusts the position of the two fixing pieces 34 according to the size of the patient's hand. Then, the patient's hand is fixed by Velcro 342. Therefore, the support plate 3 can fix the drug delivery device to hands of different sizes, improving the adaptability of the device. At the same time, the support plate 3 can be moved up and down by adjusting the fixing mechanism 4, so as to adapt to the patient's movements when they need to move in some situations, such as going to the toilet.

[0045] Example 2

[0046] This embodiment further improves upon Embodiment 1 by modifying the storage device 5, such as... Figure 1 and Figure 2 As shown, a storage device 5 is provided on the upper part of the outer surface of the fixing mechanism 4. The storage device 5 is sleeved on the upper part of the telescopic bracket 1, and the inner surface of the storage device 5 does not contact the outer surface of the telescopic bracket 1.

[0047] When patients receive intravenous infusions, the infusion tubing is often quite long. A long tubing can restrict the patient's movement. To store excess tubing and to more effectively heat the medication in the infusion solution when the temperature is low, [further measures are needed]. Figure 5 As shown, the storage device 5 includes a storage rack 51, a support frame 55 is provided at the lower end of the storage rack 51, the support frame 55 is fixedly installed on the upper part of the outer surface of the support tube 41, a protective cover 52 is provided at the upper part of the storage rack 51, two annular airbags 53 are provided on both sides of the middle part of the inner cavity of the storage rack 51, and an air supply mechanism 54 is provided on both sides of the outer surface of the storage rack 51.

[0048] Specifically, before medical staff administer an IV to a patient, they can place the excess IV tubing into the inner cavity of the storage rack 51. In cold weather, a hand warmer can also be placed into the inner cavity of the storage rack 51. Then, the protective cover 52 is placed back on top of the storage rack 51. During this process, the protective cover 52 will drive the air delivery mechanism 54 to move, causing the air delivery mechanism 54 to inflate the annular air bladder 53 in the inner cavity of the storage rack 51. This causes the annular air bladder 53 in the inner cavity of the storage rack 51 to squeeze the hand warmer placed in the inner cavity of the storage rack 51, ensuring that the hand warmer makes full contact with the excess IV tubing in the inner cavity of the storage rack 51, allowing the hand warmer to better heat the medication in the IV tubing.

[0049] Furthermore, when adjusting the height of the support platform 3, the support tube 41 will simultaneously drive the storage device 5 to move through the support frame 55. This prevents the distance between the support plate 31 and the storage frame 51 from changing when the height of the support platform 3 is adjusted, which could cause the infusion tube to tighten or droop, affecting the normal infusion process. At the same time, when the excess infusion tube is put into the inner cavity of the storage frame 51, a certain length of infusion tube can be reserved between the storage frame 51 and the hook 7 to prevent the infusion tube from being pulled when adjusting the height of the support platform 3, thus affecting the infusion process.

[0050] To store excess IV tubing and to facilitate the placement of hand warmers on either side of the inner cavity of the ring-shaped outer casing 511 by medical staff, such as... Figure 6 As shown, the storage rack 51 includes an annular outer shell 511, which is sleeved on the upper part of the telescopic bracket 1. The inner surface of the annular outer shell 511 does not contact the outer surface of the telescopic bracket 1. Both sides of the outer surface of the annular outer shell 511 are provided with connecting holes 513. Both sides of the upper part of the annular outer shell 511 are provided with arc-shaped locking rods 512 for locking the protective cover 52. Both sides of the inner cavity of the annular outer shell 511 are provided with annular placement racks 514.

[0051] Specifically, when storing excess infusion tubing, medical staff can wrap the excess tubing around the inner cavity of the two ring-shaped placement frames 514.

[0052] Furthermore, after the excess infusion tubing is placed in the inner cavity of the annular placement frame 514, the infusion tubing should enter the annular placement frame 514 through the connection hole 513 on one side, be wound around several times, and then exit through the connection hole 513 on the other side.

[0053] To facilitate squeezing the heat pack placed inside the ring-shaped outer shell 511, such as Figure 7 As shown, two annular airbags 53 located on one side are disposed on both sides of the annular placement frame 514, and the two annular airbags 53 are fixedly connected to the outer surface of the inner cavity and the inner surface of the inner cavity of the annular outer shell 511, respectively.

[0054] Specifically, when placing the hand warmer, it should be placed in the space between the ring-shaped holder 514 and the ring-shaped airbag 53.

[0055] To protect excess infusion tubing placed within the annular placement frame 514, and also to coordinate with the operation of the gas delivery mechanism 54, such as... Figure 8 As shown, the protective cover 52 includes an annular cover 521 that is adapted to the annular outer shell 511. The annular cover 521 is adapted to be used with the arc-shaped lever 512. Handles 522 are provided on both sides of the upper end of the annular cover 521. Arc-shaped push plates 523 are provided on both sides of the outer surface of the annular cover 521 near the gas delivery mechanism 54.

[0056] Specifically, when placing excess infusion tubing, the annular cap 521 needs to be lifted upwards using the handle 522 to disengage it from the annular outer shell 511. When the annular cap 521 is placed on top of the annular outer shell 511, the arc-shaped locking rod 512 can hold the annular cap 521 in place. When it is necessary to remove the annular cap 521, the handle 522 can be pulled upwards to disengage it from the annular outer shell 511.

[0057] To inflate the four annular air bladders 53 inside the annular shell 511 during the process of medical personnel fastening the protective cover 52 onto the upper part of the annular shell 511, the air delivery mechanisms 54 on both sides are activated. This causes the annular air bladders 53 to compress the heat pack placed inside the annular shell 511, ensuring full contact between the heat pack and the infusion tube placed inside the annular placement frame 514, thus better heating the medication in the infusion tube. Figure 9 and Figure 10 As shown, the gas delivery mechanism 54 includes an arc-shaped frame 541, which is fixedly installed on the outer surface of the annular shell 511. An arc-shaped piston 542 is provided in the middle of the inner cavity of the arc-shaped frame 541. The arc-shaped piston 542 is adapted to be used with the arc-shaped push plate 523. A plurality of springs 543 are provided at the lower end of the arc-shaped piston 542. Connecting pipes 544 communicating with the inner cavities of two annular airbags 53 located on one side are provided on both sides of the lower end of the arc-shaped frame 541. The connecting pipes 544 are fixedly installed at the lower end of the annular shell 511, and the connection points of the connecting pipes 544 with the arc-shaped frame 541 and the annular airbags 53 extend into the inner cavity of the annular shell 511.

[0058] Specifically, after medical staff place the excess IV tubing into the inner cavity of the storage rack 51, they replace the protective cover 52 on top of the storage rack 51. During this process, the arc-shaped push plate 523 contacts the upper end of the arc-shaped piston 542 and pushes the arc-shaped piston 542 downward. This causes the arc-shaped piston 542 to compress the air in the inner cavity of the gas delivery mechanism 54, increasing the air pressure in the inner cavity of the arc-shaped frame 541. At this time, the air in the inner cavity of the arc-shaped frame 541 is introduced through the two connecting pipes 544 into the two annular gas tubes connected to them. Inside the bladder 53, two annular air bladders 53 inflate. When the two annular air bladders 53 inflate, they squeeze the heat pack placed between the annular placement frame 514 and the annular air bladder 53, making the heat pack fit tightly against the surface of the infusion tube placed inside the annular placement frame 514. At the same time, the contact area between the heat pack and the infusion tube increases, which can better heat the medicine in the infusion tube. This avoids the phenomenon that the heating effect is not obvious when the heat pack is wrapped around the infusion tube during daily infusion, and also avoids the impact on the patient's movement.

[0059] Furthermore, during the downward movement of the arc-shaped piston 542, multiple springs 543 at the lower end of the arc-shaped piston 542 are compressed. When the protective cover 52 disengages from the storage rack 51, the springs 543 push the arc-shaped piston 542 upward. At this time, the air in the inner cavity of the annular airbag 53 flows back into the inner cavity of the arc-shaped frame 541 through the connecting pipe 544.

[0060] Furthermore, when the annular cover 521 is secured to the upper part of the outer surface of the annular shell 511 by the arc-shaped locking rod 512, the arc-shaped push plate 523 pushes the arc-shaped piston 542 downward to compress the spring 543. At the same time, the arc-shaped piston 542 introduces air into the inner cavity of the annular airbag 53. Therefore, the reaction force generated by multiple arc-shaped push plates 523 and annular airbag 53 cannot push the annular cover 521 off the outer surface of the annular shell 511.

[0061] In summary, the specific implementation method is as follows: Before medical staff administer intravenous infusion to the patient, they can wrap the excess infusion tubing around the inner cavity of the two annular placement frames 514 to prevent the excess tubing from drooping and affecting the patient's movement. A heat pack can be placed between the annular placement frame 514 and the annular air bladder 53. Then, the air delivery mechanism 54 can introduce air into the inner cavity of the annular air bladder 53, causing the annular air bladder 53 to compress the heat pack placed in the inner cavity of the placement frame 514. This ensures that the heat pack is in close contact with the surface of the infusion tubing placed in the inner cavity of the annular placement frame 514, allowing the heat pack to heat the liquid in the infusion tubing. This avoids the problem of insufficient heating effect when the heat pack is wrapped around the infusion tubing during routine infusions, which also affects the patient's movement.

[0062] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of this invention is defined by the appended claims and their equivalents.
