Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to a connector for a closed thoracic drainage tube. Background Technology
[0002] Closed thoracic drainage is a common thoracic surgical procedure used to drain pleural effusion, pneumothorax, or blood, restoring negative pressure in the pleural cavity and improving lung expansion function. The closed thoracic drainage tube, as a crucial component connecting the patient's thoracic cavity to an external negative pressure drainage device, directly impacts drainage effectiveness and the patient's recovery process. In clinical practice, various specifications of commonly used thoracic drainage tubes exist, with significant differences in diameter and wall thickness. While this diverse tube diameter design meets different clinical needs, it also introduces the problem of incompatibility between the tube and external devices.
[0003] Currently, most chest drainage devices have fixed-size interfaces. However, variations in drainage tube specifications often lead to problems such as loose connections, poor sealing, or difficulty in securing the tubes, increasing the risk of air leakage, affecting the negative pressure effect of drainage, and potentially causing infection. Furthermore, medical personnel need to use additional connectors or adjustment devices to adapt to different tube sizes, which not only increases the complexity of the procedure but also prolongs the operation time and causes additional pain for the patient. Utility Model Content
[0004] This invention provides a connector for closed thoracic drainage tubes to solve the above-mentioned technical problems.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A connector for a closed thoracic drainage tube includes an adapter disc and a flow guide support. Several conversion joints are arranged around the adapter disc, with each conversion joint vertically penetrating the adapter disc. A positioning hole is located at the center of the adapter disc. A positioning rod penetrating the positioning hole is fixed to the top surface of the flow guide support. A limit block is provided at the top of the positioning rod. An elastic component is sleeved on the positioning rod, and the elastic component is disposed between the limit block and the adapter disc. A flow guide hole communicating with any of the conversion joints is located at the center of the flow guide support.
[0007] Furthermore, several adapters are circumferentially spaced at equal intervals around the positioning hole, and the distance from the axis of each adapter to the positioning hole is equal. Adapters of any size and specification are compatible with commercially available chest drainage tubes; that is, chest drainage tubes of different specifications can be inserted into the corresponding adapters to complete the connection. Because the distance from the axis of the adapter to the positioning hole is equal, when the adapter disc is rotated around the positioning hole, it is ensured that the adapter above the drainage support is in communication with the drainage hole, i.e., the axis overlaps.
[0008] Furthermore, the opening diameters of several of the aforementioned adapters are progressively reduced. These adapters can accommodate chest drainage tubes of different diameters, resolving the issue of incompatibility between different tube diameter interfaces, and meeting clinical needs without the need for additional conversion devices.
[0009] Furthermore, the diameter of the guide hole is not smaller than the diameter of any of the adapters. When using the largest size adapter, the drainage fluid can also smoothly enter the guide hole, which ensures that all adapters can smoothly guide the drainage fluid into the drainage bottle.
[0010] Furthermore, several of the aforementioned adapters are provided with silicone sealing rings around their bottom periphery. The outer diameter of each silicone sealing ring is the same as the diameter of the guide hole, and the inner diameter of any one of the silicone sealing rings is the same as the diameter of the adapter. The silicone sealing rings, positioned around the bottom periphery of the adapter and adapted to the diameter of the guide hole, ensure a tight fit when any adapter is connected to the guide hole, guaranteeing the negative pressure environment and drainage effect of the closed thoracic drainage system, while preventing leakage of drainage fluid at the connection point.
[0011] Furthermore, the top periphery of the guide hole is provided with a notch for accommodating the silicone sealing ring. This notch allows the silicone seal to be precisely embedded into the top periphery of the guide hole, preventing displacement or detachment. In addition, the notch design ensures the silicone seal fits tightly against the connection surface of the adapter and the guide hole, enhancing sealing and preventing leakage of the drainage fluid.
[0012] Furthermore, a drainage tube is provided at the center of the bottom of the drainage support, and the drainage tube is connected to the drainage hole. The connection between the drainage tube and the drainage hole forms a complete drainage path between the chest drainage tube connected to the adapter and the external drainage bottle.
[0013] Furthermore, the interface of the guide tube is compatible with that of the external drainage bottle. This compatibility ensures a tight connection, preventing the tube from detaching or causing air or liquid leakage due to looseness or mismatch.
[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] 1. This utility model is equipped with multiple specifications of conversion connectors. By rotating and adjusting the conversion disc, the appropriate specification interface can be selected to complete quick switching and adaptation.
[0016] 2. This utility model, by setting a silicone sealing ring at the bottom of any conversion connector, can ensure good sealing performance after adjustment, so as to meet the needs of long-term high-intensity drainage.
[0017] 3. This utility model is simple and convenient to operate. By setting a universal conversion connector compatible with different specifications of chest drainage tubes, it can not only ensure a stable connection with the drainage tube, but also shorten the operation time, thereby improving the safety and nursing efficiency of chest drainage.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.
[0023] Example 1
[0024] like Figure 1-3 As shown, this utility model discloses a connector for a closed thoracic drainage tube, including a transition disc 1 and a flow guide 2. Several conversion connectors 3 are arranged around the transition disc 1, and the conversion connectors 3 vertically penetrate the transition disc 1. A positioning hole 4 is provided in the center of the transition disc 1. A positioning rod 5 that penetrates the positioning hole 4 is fixed to the top surface of the flow guide 2. A limit block 6 is provided at the top of the positioning rod 5. An elastic component 7 is sleeved on the positioning rod 5. The elastic component 7 is disposed between the limit block 6 and the transition disc 1. A flow guide hole 8 that communicates with any of the conversion connectors 3 is provided in the center of the flow guide 2.
[0025] Several adapters 3 are circumferentially spaced at equal intervals around the positioning hole 4, and the distance from the axis of each adapter 3 to the positioning hole 4 is equal. Specifically, adapters 3 of any size and specification are compatible with commercially available chest drainage tubes; that is, chest drainage tubes of different specifications can be inserted into the corresponding adapter 3 to complete the connection. Since the distance from the axis of the adapter 3 to the positioning hole 4 is equal, when the adapter disc 1 is rotated around the positioning hole 4, it can be ensured that the adapter 3 above the guide support 2 is in communication with the guide hole 8, i.e., the axis overlaps.
[0026] The opening diameters of the several adapters 3 are progressively reduced. Specifically, the several adapters 3 can be adapted to chest drainage tubes of different diameters, solving the problem of mismatch between different tube diameter interfaces, and can meet clinical needs without the need for additional conversion devices.
[0027] The diameter of the guide hole 8 is not smaller than the diameter of any of the conversion connectors 3. Specifically, when the largest size conversion connector 3 is selected, the drainage fluid can also smoothly enter the guide hole 8, which ensures that all conversion connectors 3 can smoothly guide the drainage fluid into the drainage bottle.
[0028] Each of the several conversion connectors 3 has a silicone sealing ring 9 around its bottom periphery. The outer diameter of each silicone sealing ring 9 is the same as the diameter of the guide hole 8, and the inner diameter of any one of the silicone sealing rings 9 is the same as the diameter of the conversion connector 3. Specifically, the silicone sealing ring 9 is located around the bottom periphery of the conversion connector 3 and is adapted to the diameter of the guide hole 8. This ensures a tight fit when any conversion connector 3 is connected to the guide hole 8, guaranteeing the negative pressure environment and drainage effect of the closed thoracic drainage system, while preventing leakage of drainage fluid at the connection point.
[0029] The top periphery of the guide hole 8 is provided with a notch 10 for accommodating the silicone seal 9 ring. Specifically, the notch 10 allows the silicone seal 9 to be precisely embedded in the top periphery of the guide hole 8, preventing displacement or detachment. In addition, the design of the notch 10 allows the silicone seal 9 to fit tightly against the connection surface of the adapter 3 and the guide hole 8, enhancing the sealing performance and preventing leakage of drainage fluid.
[0030] A drainage tube 11 is provided at the center of the bottom of the drainage support 2, and the drainage tube 11 is connected to the drainage hole 8. Specifically, the drainage tube 11 is connected to the drainage hole 8, forming a complete drainage path between the chest drainage tube connected to the adapter 3 and the external drainage bottle.
[0031] The guide tube 11 is adapted to the interface of the external drainage bottle. Specifically, the adaptation between the guide tube 11 and the interface of the external drainage bottle can achieve a tight connection, avoiding pipe detachment or air / liquid leakage due to looseness or interface mismatch.
[0032] Example 2
[0033] Based on Example 1, this example proposes a specific implementation process for a connector for a closed thoracic drainage tube.
[0034] The specific implementation principle and process are as follows:
[0035] Based on the specifications of the chest drainage tube used by the patient, select a matching adapter 3 and rotate the adapter 3 above the guide hole 8. During operation, hold the outer wall of the adapter disc 1 and pull it upwards. At this time, the elastic component 7 undergoes elastic deformation. When the corresponding adapter 3 moves directly above the guide hole 8, release the adapter disc 1. The adapter disc 1 is now aligned with the guide hole 8, completing the conversion adjustment. Next, insert the chest drainage tube into the selected adapter 3, and simultaneously connect the bottom of the guide tube 11 to the external drainage bottle. After the system is assembled, the drainage fluid in the chest cavity, under negative pressure, flows smoothly into the drainage bottle through the chest drainage tube, adapter 3, guide hole 8, and guide tube 11, achieving closed drainage operation.
[0036] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
