Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an adjustable speed chest drainage bag. Background Technology

[0002] Chest drainage bags are important medical devices used in clinical practice to drain pleural effusion, gas, or blood. Traditional chest drainage bags are usually connected to the chest cavity through a drainage tube and rely on gravity to achieve drainage. The flow rate is often controlled by medical staff manually adjusting the suspension height of the drainage bag, or indirectly by squeezing the drainage tube through external clamping devices (such as roller clamps or spring clamps) to change the cross-sectional area of ​​the lumen.

[0003] However, the existing technology has the following drawbacks: (1) Low flow rate adjustment accuracy: The method of controlling the flow rate by adjusting the height of the drainage bag is limited by space conditions and cannot achieve fine adjustment; while the external clamping device is prone to deformation or even damage to the drainage tube due to uneven clamping force, which may affect the sealing performance after long-term use. (2) Inconvenient operation and infection risk: Frequent manual adjustment of the clamping device or adjustment of the height requires multiple contacts with the drainage tube and valve, which increases the risk of contamination and infection. (3) Lack of intuitive flow rate indication: Existing drainage bags usually do not have flow rate scale markings, and medical staff need to judge the flow rate based on experience, which can easily lead to drainage that is too fast or too slow. Drainage that is too fast may cause complications such as chest pain and re-expansion pulmonary edema in patients, while drainage that is too slow will prolong the treatment period. Utility Model Content

[0004] This invention proposes a thoracic drainage bag with an integrated flow rate adjustment mechanism, which achieves precise and convenient flow rate control through mechanical structural innovation.

[0005] The technical solution adopted by this utility model is as follows: an adjustable speed chest drainage bag, including a drainage bag body, a drainage tube connected to the top of the drainage bag body, a flow rate regulating mechanism installed on the drainage tube, the flow rate regulating mechanism including a speed regulating housing sleeved on the outside of the drainage tube, a rotating shaft rotatably connected to the speed regulating housing, a gear and a flow rate pointer fixedly connected to both ends of the rotating shaft located on the outside of the speed regulating housing, a flow limiting cam fixedly sleeved on the outside of the rotating shaft inside the speed regulating housing and in contact with the drainage tube, and a drain pipe connected to the bottom of the drainage bag body and a drain valve provided on the drain pipe.

[0006] As a further improvement of this utility model, the surface of the main body of the drainage bag is provided with a liquid level scale bar.

[0007] As a further improvement of this utility model, a connector is provided at the end of the drainage tube away from the main body of the drainage bag.

[0008] As a further improvement of this utility model, both ends of the rotating shaft are rotatably connected to the speed regulating housing through damping bearings.

[0009] As a further improvement of this utility model, the speed regulating housing is slidably connected to a rack that meshes with a gear on the side away from the flow rate pointer, and the surface of the rack is provided with a friction scale.

[0010] As a further improvement of this utility model, a T-shaped slider is fixedly connected to the inner side of the rack, and a T-shaped groove is provided on the speed regulating housing for the T-shaped slider to slide.

[0011] As a further improvement of this utility model, a flow rate scale is provided on the edge of the surface of the speed regulating housing away from the gear.

[0012] The beneficial effects of this utility model are as follows: This utility model achieves the rotation of the flow rate pointer by contacting the flow-limiting cam in the flow rate adjustment mechanism with the drainage tube, and by driving the rotating shaft to rotate through the transmission effect of the rack and pinion. Medical staff can intuitively adjust the required flow rate according to the flow rate scale, avoiding the problem of inaccurate flow rate control caused by space limitations or uneven clamping force in traditional methods. At the same time, the design of the flow rate scale and flow rate pointer allows medical staff to clearly understand the current flow rate, avoiding the problem of drainage being too fast or too slow due to experience judgment, and ensuring the safety and effectiveness of the drainage process.

[0019] The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly mentioned in this specification are defined relative to their structure and are relative concepts. Therefore, they may vary depending on their location and usage; thus, these or other directional terms should not be interpreted as restrictive terms.

[0020] The singular forms “a,” “the,” and “the” used in this specification are intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes one or more of the associated listed items, any or all possible combinations thereof.

[0021] To make the technical problems to be solved, the technical solutions, and the beneficial effects of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0022] This utility model provides the following: Figure 1-5 The adjustable-speed chest drainage bag shown includes a drainage bag body 1, a drainage tube 2 connected to the top of the drainage bag body 1, a flow rate adjustment mechanism installed on the drainage tube 2, the flow rate adjustment mechanism includes a speed adjustment housing 3 sleeved on the outside of the drainage tube, a rotating shaft 4 rotatably connected to the speed adjustment housing 3, gears 5 and flow rate pointers 6 located on the outside of the speed adjustment housing 3 respectively fixedly connected to both ends of the rotating shaft 4, a flow limiting cam 7 fixedly sleeved on the outside of the rotating shaft 4 and in contact with the drainage tube 2, and a drain pipe 13 connected to the bottom of the drainage bag body 1 and a drain valve provided on the drain pipe 13.

[0023] like Figure 1-3 As shown, the surface of the drainage bag body 1 in this utility model is provided with a liquid level scale bar, and the edge of the surface of the speed regulating housing 3 away from the gear 5 is provided with a flow rate scale. Medical staff can observe the liquid level scale bar to understand the amount of liquid in the drainage bag body 1 so as to perform drainage operations in a timely manner.

[0024] like Figure 1-3 As shown, in this utility model, the end of the drainage tube 2 away from the main body 1 of the drainage bag is provided with a connector 8. The connector 8 facilitates a stable connection with the chest drainage tube, ensuring smooth drainage.

[0025] like Figure 4 As shown, in this utility model, both ends of the rotating shaft 4 are rotatably connected to the speed regulating housing 3 through damping bearings 9, which increases the damping feel of the rotating shaft 4, enabling medical staff to control the rotation angle of the rotating shaft 4 more stably and accurately when adjusting the flow rate, thereby further improving the accuracy of flow rate control.

[0026] like Figure 4 and Figure 5 As shown, in this utility model, the speed regulating housing 3 is slidably connected to a rack 10 that meshes with a gear 5 on the side away from the flow rate pointer 6, and the surface of the rack 10 is provided with a friction scale. A T-shaped slider 11 is fixedly connected to the inner side of the rack 10. The speed regulating housing 3 is provided with a T-shaped groove 12 for the T-shaped slider 11 to slide. Medical staff can drive the gear 5 to rotate by sliding the rack 10. Since the gear 5 is fixedly connected to the rotating shaft 4, it can drive the rotating shaft 4 to rotate together, thereby realizing the rotation of the flow rate pointer 6.

[0027] Working Principle: In practical implementation, medical staff first connect the drainage tube 2 to the patient's chest drainage tube via the connector 8, ensuring a stable connection and good sealing. Then, medical staff can observe the liquid level scale on the surface of the drainage bag body 1 to understand the current fluid volume. When it is necessary to adjust the drainage speed, medical staff can slide the rack 10, which meshes with the gear 5, thereby driving the gear 5 to rotate. Since the gear 5 is fixedly connected to the rotating shaft 4, the rotation of the gear 5 will drive the rotating shaft 4 to rotate as well. The rotation of the rotating shaft 4 will cause the flow-limiting cam 7 to rotate within the speed-adjusting housing 3, thereby changing the contact area between the flow-limiting cam 7 and the drainage tube 2, thus achieving precise adjustment of the drainage speed.

[0028] During adjustment, medical staff can observe the position of the flow rate pointer 6 on the flow rate scale to intuitively understand the current drainage rate. Since both ends of the rotating shaft 4 are rotatably connected to the speed control housing 3 via damping bearings 9, the damping sensation during rotation is increased, allowing medical staff to control the rotation angle more stably and precisely during adjustment, thereby further improving the accuracy of flow rate control. When the amount of liquid in the drainage bag body 1 reaches a certain level, medical staff can open the drain valve to drain the liquid from the drain pipe 13.

[0029] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
