Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a safe connection device for a drainage tube. Background Technology

[0002] In some surgical drainage procedures, such as cerebrospinal fluid drainage, a section of the drainage tube needs to be inserted into the brain cavity so that the inserted end can be inserted into the corresponding organ for drainage. The other end of the drainage tube is connected externally to a drainage system (such as a drainage drip bottle or drainage bag). Because the drainage tube and drainage system located outside the body are not easily separated, the drainage system can be easily pulled during patient movement after insertion, causing the drainage tube to shift and potentially damaging the patient's brain tissue, which is detrimental to the patient's recovery.

[0003] Current practices aim to fix the drainage tube to the outside of the body as much as possible to reduce the pulling force that is directly transmitted to the inside of the drainage tube. Although this has improved the risk of dislodgement to some extent, it is still inevitable that the inserted end will be pulled out of the body when the external pulling force is large. Accidental tube removal incidents occur from time to time in clinical practice. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a safe connection device for drainage tubes. This solves the technical problem that although the existing drainage tubes are fixed on the outside of the body, which improves the risk of detachment to a certain extent, the insertion end is still inevitably pulled out of the body when the external pulling force is large.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] This utility model embodiment provides a drainage tube safety connection device, including: a connecting tube, a drainage tube connection end disposed at the inlet end of the connecting tube, and a drainage tube connection end disposed at the outlet end of the connecting tube. The drainage tube connection end is used to connect to the outlet end of the drainage tube, and the drainage tube connection end is used to connect to the inlet end of the drainage tube. The drainage tube connection end and the drainage tube connection end are connected through the connecting tube. The connecting tube is made of an elastic material, such that the connecting tube has a first state and a second state with different lengths between the drainage tube connection end and the drainage tube connection end.

[0007] Furthermore, the connecting pipe has several spiral turns.

[0008] Furthermore, the drainage tube connection end includes a first tee connector, which has three interconnected interfaces: a first interface, a second interface, and a third interface. The first interface of the first tee connector is connected to the inlet end of the connecting tube, the second interface of the first tee connector is used to connect to the outlet end of the drainage tube, and the third interface of the first tee connector is used to connect to an external syringe.

[0009] Furthermore, a heparin cap is provided on the third interface of the first tee connector.

[0010] Furthermore, the drainage tube connection end also includes a first Luer connector, which is connected between the first interface of the first tee connector and the inlet end of the connection tube.

[0011] Furthermore, the first and second interfaces of the first tee connector are coaxial, and the central axis of the third interface of the first tee connector is perpendicular to the central axis of the first interface of the first tee connector.

[0012] Furthermore, the drainage tube connection end includes a second tee connector, which has three interconnected interfaces: a first interface, a second interface, and a third interface. The first interface of the second tee connector is connected to the outlet end of the connecting tube, the second interface of the second tee connector is used to connect to the inlet end of the drainage tube, and the third interface of the second tee connector is used to connect to an external syringe.

[0013] Furthermore, a heparin cap is provided on the third interface of the second three-way connector.

[0014] Furthermore, the drainage pipe connection end also includes a second Luer connector, which is connected between the first interface of the second tee connector and the outlet end of the connecting pipe.

[0015] Furthermore, the first and second interfaces of the second tee connector are coaxial, and the central axis of the third interface of the second tee connector is perpendicular to the central axis of the first interface of the second tee connector.

[0016] The drainage tube safety connection device of this utility model adopts an elastic connecting tube, which can freely extend and retract between the drainage tube connection end and the drainage tube connection end to form a first state and a second state with different lengths. This can effectively reduce the pulling of the drainage tube caused by changes in patient position or treatment needs, thereby ensuring the smoothness and safety of the drainage process.

[0032] Please see the appendix Figures 1 to 5 This utility model provides a drainage tube safety connection device 1, including: a connecting tube 11, a drainage tube connection end 12 disposed at the inlet end of the connecting tube 11, and a drainage tube connection end 13 disposed at the outlet end of the connecting tube 11. The drainage tube connection end 12 is used to connect to the outlet end of the drainage tube 2, and the drainage tube connection end 13 is used to connect to the inlet end of the drainage tube 2. The drainage tube connection end 12 and the drainage tube connection end 13 are connected through the connecting tube 11. The connecting tube 11 is made of an elastic material, such that the connecting tube 11 has a first state and a second state with different lengths between the drainage tube connection end 12 and the drainage tube connection end 13. Optionally, the connecting tube 11 can be made of TPU material or other easily processed elastic tube materials. It should be explained that the inlet and outlet ends mentioned above and below are described with reference to the flow direction of the fluid from the inlet pipe connection end 12 to the inlet pipe connection end 13 in the inlet pipe safety device 1, and do not restrict the flow direction of the liquid in the inlet pipe safety connection device 1.

[0033] In this embodiment, since the connecting tube 11 is made of elastic material, it has good elastic deformation ability and recovery. Therefore, when the drainage tube 2 is pulled by external force, the connecting tube 11 can deform, absorb and disperse the pulling force, thereby playing a buffering role. By providing a pulling buffer, it effectively avoids the situation where the insertion end of the drainage tube 2 is pulled out of the body, reducing the surgical risk. In addition, the design of the connecting tube 11 also allows its length to be adjusted within a certain range to adapt to the physical condition and activity needs of different patients. This flexibility not only improves the patient's comfort, but also further enhances the stability and safety of the drainage tube 2 inserted into the head.

[0034] Furthermore, the connecting tube 11 has several spiral turns. It should be explained that the first state of the connecting tube 11 is its natural state, where adjacent turns of the tube are close together, and the length of the connecting tube 11 between the drainage tube connection end 12 and the drainage channel connection end 13 is the shortest. The second state of the connecting tube 11 is its stretched state. In this state, the connecting tube 11 is subjected to a tensile force from either the drainage tube connection end 12 or the drainage channel connection end 13. The spirally wound tube is stretched, increasing the length of the connecting tube 11 between the drainage tube connection end 12 and the drainage channel connection end 13. This absorbs and buffers the tensile force transmitted from either the drainage tube connection end 12 or the drainage channel connection end 13, preventing the tensile force from being directly transmitted to the drainage tube 2 and avoiding any pulling of the drainage tube 2 inserted into the body. When the external force stops, due to the restorative properties of the elastic material, the connecting tube 11 will gradually return to its original natural state. Understandably, when the spirally wound tube is stretched by external force, it can deform like a spring, absorbing and dispersing the stretching force, thus playing a buffering role and reducing the risk of the drainage tube 2 falling off or causing harm to the patient.

[0035] Specifically, the drainage tube connection end 12 includes a first three-way connector 121. The first three-way connector 121 has three interconnected interfaces: a first interface, a second interface, and a third interface. The first interface of the first three-way connector 121 is connected to the inlet end of the connecting tube 11. The second interface of the first three-way connector 121 is used to connect to the outlet end of the drainage tube 2. The third interface of the first three-way connector 121 is used to connect to an external syringe. Preferably, the first and second interfaces of the first three-way connector 121 are coaxial, and the central axis of the third interface of the first three-way connector 121 is perpendicular to the central axis of the first interface of the first three-way connector 121. It can be understood that the first three-way connector 121 serves as a sealing connection, and the laterally positioned third interface of the first three-way connector 121 facilitates injection and aspiration operations using an external syringe.

[0036] Optionally, a heparin cap is provided on the third interface of the first three-way connector 121. It is understood that the heparin cap primarily serves a sealing function and facilitates drug injection. Preferably, the heparin cap on the third interface of the first three-way connector 121 is detachable, allowing medical personnel to choose to attach or remove the heparin cap from the third interface of the first three-way connector 121 according to injection or aspiration needs. With the heparin cap on, drug injection is convenient; without the heparin cap, aspiration is convenient.

[0037] For further details, please refer to Figure 1 and Figure 5The drainage tube connection end 12 also includes a first Luer connector 122, which connects to the first interface of the first tee connector 121 and the inlet end of the connecting tube 11. It is understood that the first Luer connector 122 serves a sealing connection function, making the connection between the first tee connector 121 and the connecting tube 11 tighter. Optionally, the first Luer connector 122 can be a male Luer connector. It is understood that Luer connectors are a standard connector widely used in medical device connections, designed for easy connection, disconnection, and tight sealing. Luer connectors are generally divided into male and female types, connected by rotation and tightening.

[0038] Furthermore, the drainage tube connection end 13 includes a second tee connector 131. The second tee connector 131 has three interconnected interfaces: a first interface, a second interface, and a third interface. The first interface of the second tee connector 131 is connected to the outlet end of the connecting tube 11. The second interface of the second tee connector 131 is used to connect to the inlet end of the drainage tube 2. The third interface of the second tee connector 131 is used to connect to an external syringe. Preferably, the first and second interfaces of the second tee connector 131 are coaxial, and the central axis of the third interface of the second tee connector 131 is perpendicular to the central axis of the first interface. It is understood that the second tee connector 131 serves as a sealing connection, and the laterally positioned third interface of the second tee connector 131 facilitates injection and aspiration operations using an external syringe.

[0039] Furthermore, a heparin cap is provided on the third interface of the second three-way connector 131. It is understood that the heparin cap primarily serves a sealing function and facilitates drug injection. Preferably, the heparin cap on the third interface of the second three-way connector 131 is detachable, allowing medical personnel to choose to attach or remove the heparin cap from the third interface of the second three-way connector 131 according to injection or aspiration needs. With the heparin cap on, drug injection is convenient; without it, aspiration is convenient.

[0040] For further details, please refer to Figure 1 and Figure 5 The drainage pipe connection end 13 also includes a second Luer connector 132, which connects to the first interface of the second tee connector 131 and the outlet end of the connecting pipe 11. It is understood that the second Luer connector 132 serves a sealing function, making the connection between the second tee connector 131 and the connecting pipe 11 tighter. Optionally, the second Luer connector 132 can be a female Luer connector.

[0041] like Figure 3 , Figure 4As shown, in a possible application scenario, the drainage tube 2 has a balloon at its front end and is inserted into the cranium. The portion between the front and rear ends of the drainage tube 2 is subcutaneously inserted, while the rear end of the drainage tube 2 protrudes from the scalp and is fixed to the head. The drainage tube connection end 12 of the drainage tube safety connection device 1 of this application is connected to the rear end of the drainage tube 2. The drainage tube path connection end 13 of the drainage tube safety connection device 1 of this application is connected to the drainage tube 2 path. When the patient pulls on the drainage tube 2 path, the drainage tube safety connection device 1 of this application is activated, and the drainage tube 2 path pulls on the drainage tube safety connection device 1 of this application, straightening the connecting tube 11 in the drainage tube safety connection device 1 to buffer the pulling force of external force on the drainage tube 2. When the patient stops pulling on the drainage tube 2 path, the external force pulling on the drainage tube 2 path disappears, and the drainage tube safety connection device 1 of this application returns to its original state. Throughout the entire process described above, neither the drainage tube connection end 12 nor the drainage tube 2 moved, effectively preventing the insertion end of the drainage tube 2 from being pulled out of the body.
