Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, and more specifically, to a damping component and an angiography injector. Background Technology

[0002] Cardiovascular angiography involves rapidly injecting a contrast agent containing organic compounds, transparent under X-ray irradiation, into the bloodstream. This allows the heart and major blood vessels to be visualized under X-ray. Simultaneously, methods such as rapid radiography, videography, or magnetic tape recording are used to capture the imaging process. The results show the flow sequence of the contrast-containing blood and the filling status of the heart and major blood vessels, thus revealing physiological and anatomical changes in the heart and major blood vessels. It is a valuable method for diagnosing cardiovascular diseases.

[0003] Cardiovascular angiography typically requires the use of an angiography injector, which usually has the function of horizontal and vertical rotation. However, in the current technology, its rotation range is limited, and when rotated to more than 90 degrees, it is easy to suddenly fall, causing damage to the injection head and even affecting the normal progress of the medical diagnosis process. Utility Model Content

Therefore, this damping assembly can improve the situation where the injection head is prone to sudden falls in existing technologies.

[0032] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0033] Please refer to the following: Figure 1 and Figure 2 This embodiment provides a damping component 11, which is applied in medical devices such as angiography injectors 10. Specifically, this damping component 11 can be used in medical devices where the rotation of components requires damping force. Furthermore, this damping component 11 can improve the situation where the injection head 12 of the angiography injector 10 is prone to sudden drop in the prior art.

[0034] In this embodiment, the application of the damping component 11 to the angiography injector 10 is used as an example. The angiography injector 10 includes at least two parts: an injection head 12 and a movable base 13. The injection head 12 is used to inject a drug into the target body, and the movable base 13 enables the overall movement of the angiography injector 10.

[0035] In this embodiment, the damping assembly 11 includes a main body 100, a first connecting seat 200, a second connecting seat 300, and a pressure regulating component 420400. The first connecting seat 200 is used to connect to the injection head 12; the first connecting seat 200 is rotatably connected to the main body 100. The second connecting seat 300 is used to rotatably connect to the movable base 13; the second connecting seat 300 is fixedly connected to the main body 100. Generally, the plane containing the rotation direction of the injection head 12 and the first connecting seat 200 relative to the main body 100 is perpendicular to the plane containing the rotation direction of the second connecting seat 300 relative to the movable base 13. In general application environments, the plane containing the rotation direction of the injection head 12 and the first connecting seat 200 is a vertical plane, while the plane containing the rotation direction of the second connecting seat 300 is a horizontal plane. Additionally, the pressure regulating member 420400 includes a pressure member 410 and an adjusting member 420; the pressure member 410 is disposed through the main body 100, and one end of the pressure member 410 and the main body 100 together clamp at least part of the first connecting seat 200; the adjusting member 420 is threadedly connected to the other end of the pressure member 410, and the adjusting member 420 is used to rotate relative to the pressure member 410 to adjust the magnitude of the force exerted by the pressure member 410 and the main body 100 clamping the first connecting seat 200.

[0036] When the injection head 12 rotates, it rotates together with the first connecting seat 200. The first connecting seat 200 is clamped by the main body 100 and the pressure member 410. This clamping action provides a certain frictional force to the first connecting seat 200, thus damping its rotation. Based on this, by turning the adjusting member 420, the force exerted by the pressure member 410 and the main body 100 clamping the first connecting seat 200 can be adjusted, thereby adjusting the frictional force and consequently, the damping effect on the rotation of the first connecting seat 200. For example, increasing the force exerted by the pressure member 410 and the main body 100 clamping the first connecting seat 200 increases the frictional force that the first connecting seat 200 needs to overcome, thus increasing the damping effect; conversely, decreasing the force exerted by the pressure member 410 and the main body 100 clamping the first connecting seat 200 decreases the frictional force that the first connecting seat 200 needs to overcome, thus decreasing the damping effect.

[0037] As described above, when the damping component 11 is applied to the angiography injector 10, the injection head 12 is connected to the first connecting seat 200 to form a whole and can rotate relative to the main body 100; while the second connecting seat 300 is connected to the movable base 13 and can rotate relative to the movable base 13. When the adjusting member 420 is screwed relative to the pressure member 410, the force exerted by the pressure member 410 on the first connecting seat 200 can be adjusted, thereby adjusting the friction between the first connecting seat 200 and the main body 100, achieving the purpose of adjusting the rotational damping of the first connecting seat 200. Based on this, by adjusting the rotational damping of the first connecting seat 200, sufficient rotational damping can be maintained when the first connecting seat 200 and the injection head 12 rotate synchronously to any position, ensuring a stable posture for both and effectively preventing the injection head 12 from suddenly falling. Therefore, the damping component 11 can improve the situation where the injection head 12 is prone to sudden falling in the prior art.

[0038] In this embodiment, a cylindrical protrusion 101 is provided at the middle of one end of the main body 100 to form a boss at the end of the main body 100; a stepped hole is provided at the center of the first connecting seat 200, and the stepped hole is rotatably engaged with the boss; the pressure member 410 passes through the center hole of the first connecting seat 200 and presses the first connecting seat 200 from the end of the first connecting seat 200 away from the main body 100.

[0039] Furthermore, in this embodiment, the damping assembly 11 further includes a damping pad 110 and a fixing plate 120, with the main body 100 and the first connecting seat 200 jointly clamping the damping pad 110 and the fixing plate 120; the damping pad 110 contacts the first connecting seat 200, and the fixing plate 120 contacts the main body 100. That is, both the damping pad 110 and the fixing plate 120 are disposed between the main body 100 and the first connecting seat 200. The fixing plate 120 is sleeved on the cylindrical protrusion 101 at the end of the main body 100 and adheres to the end face corresponding to the bottom of the cylindrical protrusion 101. Additionally, the damping pad 110 is at least partially connected to the fixing plate 120 to fix the damping pad 110. Thus, during the rotation of the first connecting seat 200, the relative movement between the first connecting seat 200 and the damping pad 110 provides a frictional damping force to the first connecting seat 200 through the damping pad 110.

[0040] The damping pad 110 provides a certain damping force to the first connecting seat 200. Even when the pressure applied by the pressure member 410 to the first connecting seat 200 is small, the damping pad 110 can ensure that the first connecting seat 200 has a certain damping, further preventing the injection head 12 from suddenly falling.

[0041] Optionally, in this embodiment, the damping pad 110 includes a first damping portion 111 and a second damping portion 112. The first damping portion 111 is cylindrical and is sleeved on the main body 100, that is, the first damping portion 111 is sleeved on the cylindrical protrusion 101. The first connecting seat 200 is sleeved outside the first damping portion 111; when the first connecting seat 200 rotates relative to the main body 100, the first damping portion 111 provides damping to the first connecting seat 200. The second damping portion 112 is sheet-shaped and is clamped between the first connecting seat 200 and the fixing plate 120. The second damping portion 112 is connected to the fixing plate 120, that is, the damping pad 110 as a whole can be fixed through the fixed connection between the second damping portion 112 and the fixing plate 120.

[0042] In this embodiment, the damping assembly 11 further includes a rolling element 130, which is clamped between the pressure element 410 and the first connecting seat 200. When the first connecting seat 200 rotates relative to the main body 100, the rolling element 130 rolls between the pressure element 410 and the first connecting seat 200. The rolling element 130 facilitates relative rotation between the first connecting seat 200 and the pressure element 410, preventing jamming due to excessive pressure. Furthermore, the static friction force that needs to be overcome during the transition of the first connecting seat 200 from a stationary state to a rotating state is smaller than that without the rolling element 130, which is more conducive to the initial rotation of the first connecting seat 200. Moreover, with the rolling element 130, the difference between static friction and rolling friction is not significant, resulting in a better operating feel for the operator.

[0043] Optionally, the rolling element 130 is a planar thrust needle roller bearing. Of course, in some other embodiments, a planar ball bearing or the like may also be used.

[0044] In this embodiment, the pressure member 410 includes a holding portion 411 and a connecting shaft 412. The holding portion 411 is located at one end of the connecting shaft 412 and is disc-shaped. The holding portion 411 and the main body 100 together clamp the first connecting seat 200. The connecting shaft 412 passes through the main body 100, and the end of the connecting shaft 412 away from the holding portion 411 is threadedly engaged with the adjusting member 420. The overall cross-section of the pressure member 410 is T-shaped. The connecting shaft 412 extends from the end of the cylindrical protrusion 101, and the holding portion 411 is located at the end of the connecting shaft 412 and presses against the first connecting seat 200.

[0045] Furthermore, in this embodiment, the damping assembly 11 also includes a lock nut 430, which is threadedly engaged with the pressure member 410 and abuts against the adjusting member 420. The lock nut 430 restricts the movement of the adjusting member 420, ensuring that the position of the adjusting member 420 is fixed, thus preventing the adjusting member 420 from loosening and causing a change in the damping effect. This ensures the stability of the pressure member 410 after adjustment, thereby ensuring the stability of the first connecting seat 200.

[0046] In this embodiment, the second connecting seat 300 is inserted into the body 100, and the pressure member 410 passes through the second connecting seat 300. Inserting the second connecting seat 300 into the body 100 and allowing the pressure member 410 to pass through the second connecting seat 300 makes the structure of the body 100 more compact and improves its overall integrity. It also allows multiple components to reinforce each other, ensuring the stability of the overall structure.

[0047] Furthermore, the main body 100 has an assembly groove 102 at the end away from the first connecting seat 200; the damping assembly 11 also includes a connector, which passes through the bottom wall of the assembly groove 102 and connects to the second connecting seat 300 to fix the second connecting seat 300 and the main body 100; the end of the pressure member 410 away from the first connecting seat 200 extends into the assembly groove 102, and the adjusting member 420 is located in the assembly groove 102; the damping assembly 11 also includes a cover 103, which is inserted into the assembly groove 102 to close the assembly groove 102. On the one hand, placing the adjusting member 420 and the anti-loosening nut 430 in the assembly groove 102 can prevent the adjusting member 420 and the anti-loosening nut 430 from being affected by external objects, ensuring their stability; on the other hand, it can also prevent the pressure member 410, the adjusting member 420, and the anti-loosening nut 430 from being exposed and affecting the appearance. In addition, the cover 103 provides further protection.

[0048] Based on the damping component 11 provided above, this embodiment also provides an angiography injector 10, which adopts the aforementioned...

[0049] In summary, in the damping assembly 11 and angiography injector 10 provided in this embodiment, the injection head 12 is connected to the first connecting seat 200 to form a whole and can rotate relative to the main body 100; while the second connecting seat 300 is connected to the movable base 13 and can rotate relative to the movable base 13. When the adjusting member 420 is screwed relative to the pressure member 410, the force exerted by the pressure member 410 on the first connecting seat 200 can be adjusted, thereby adjusting the friction between the first connecting seat 200 and the main body 100, achieving the purpose of adjusting the rotational damping of the first connecting seat 200. Based on this, by adjusting the rotational damping of the first connecting seat 200, sufficient rotational damping can be maintained when the first connecting seat 200 and the injection head 12 rotate synchronously to any position, ensuring a stable posture for both and effectively preventing the injection head 12 from suddenly falling. Therefore, this damping assembly 11 can improve the situation where the injection head 12 is prone to sudden falling in the prior art. Furthermore, the damping component 11 has a simple structure, and even if wear occurs later, it is easy to disassemble and maintain, reducing maintenance costs.

[0050] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
