In order to make the technical field of the present invention better understand, the present invention will be described in detail with reference to the accompanying drawings and the detailed description.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a clinical joint connector according to an embodiment of the present invention.
The utility model provides a clinical joint connecting piece, the structure is shown in figure 1, including first adapting unit 2, second adapting unit 4 and be used for connecting the transition part 3 of the two. Wherein, first connecting part 2 includes plug tube 21, and inverted tower type joint 1 can insert plug tube 21 in, and the second connecting part includes connecting cap 41, connects cap 41 central authorities and is equipped with the via hole that runs through along the thickness direction, and the periphery of via hole is equipped with screwed pipe 42 that is used for connecting threaded joint 5, and the transition piece is roughly tubulose, and it includes first end 31 and second end 32, and the transition piece has the intercommunicating pore that runs through along the axial. The insertion tube 21 can be inserted into the first end 31 of the transition piece through the communication hole while being fixed with the first end 31 by a snap structure. The connecting cap 41 of the second connecting part 4 can be sleeved on the periphery of the second end 32, and then the second connecting part 4 is connected with the first connecting part 2 through the transition part 3. After connection, the communication hole of the transition member 3 communicates with the through hole of the connection cap 41, so that the interiors of the first and second connection parts 2 and 4 communicate with each other, and the medicine can flow in the clinical joint connection.
Alternatively, the connection cap 41 and the second end 32 may be connected by means of adhesive fixation, screw connection, or the like, thereby improving the connection strength. In addition, the clamping structure between the insertion tube 21 and the first end 31 comprises a clamping groove 22 on the outer side wall of the insertion tube 21 and a clamping ring 33 on the inner side wall of the communication hole. The clamping groove 22 and the clamping ring 33 extend along the circumferential direction of the insertion pipe and the communication hole respectively. After the plug pipe 21 is inserted into the communicating hole, the clamping ring 33 can be embedded into the clamping groove 22, and the clamping ring 33 can bear the tensile force with the side wall of the clamping groove 22 in a matched mode, so that the connection is more stable.
In this embodiment, the transition component 3 is inserted and matched with the first connecting piece, and is fixed through the clamping structure, so that the transition component and the first connecting piece can bear the tensile force. The transition part 3 is connected with the second connecting part 4 through bonding, screw connection and the like, and can bear large tensile force. Further, the structure of the clinical joint connecting piece is firmer, and the clinical joint connecting piece is prevented from loosening or leaking in the using process.
Alternatively, the end of the bayonet tube 21 to which the transition piece 3 is connected is reduced in diameter to form a necked down configuration. As shown in figure 1, the periphery of the constriction forms a slot 22, the inner side of the constriction forms an annular surface facing away from the transition part 3, and the medicament normally flows from the second connecting part 4 to the first connecting part 2 during use of the clinical joint connection, so that the annular surface is provided with a one-way valve 6. The check valve 6 is opened when the medicine normally flows, and the check valve 6 is closed when the medicine reversely flows. Specifically, 6 chooseness duckbill valves are selected for use to check valve, and its export orientation is far away from the direction of transition part 3, is a style of calligraphy when the export of duckbill valve is closed, and the lateral wall of its side is laminated mutually, and liquid reverse flow's pressure is big more, and the export closure of duckbill valve is inseparabler, and then can play good non return function.
Further, in order to improve the connection strength between the inserting pipe 21 and the transition part 3, a fixing ring 24 is arranged at one end of the necking structure, which is far away from the annular surface, and the fixing ring 24 and the annular surface are respectively positioned at two sides of the clamping groove 22. The retainer ring 24 extends radially outwardly to increase the area of engagement with the snap ring 33, and the pulling force experienced by the clinical joint connection is generally in the direction of the transition member 3, so that the retainer ring 24 can subject the clinical joint connection to a greater pulling force.
Furthermore, the first connecting part 2 further comprises a sleeve 23 located on the periphery of the insertion pipe 21, an annular cavity is formed between the sleeve 23 and the insertion pipe 21, the first end 31 of the transition part 3 is arranged in the cavity, the sleeve 23 covers the first end 31 from the outside, and the sleeve 23 and the insertion pipe 21 extrude the first end 31, so that the friction force between the first end 31 and the first connecting part 2 is increased, and the connection firmness is further improved.
Optionally, first connecting part 2 is the flexible glue structure, and transition part 3 is the ebonite structure, and the flexible glue structure has the material softness, frictional force is big and advantages such as changeability, and first connecting part 2 adopts the flexible glue material can increase its and first end 31 and with fall tower type and connect the frictional force between 1. Meanwhile, the sleeve 23 can be manufactured by two-time injection molding, so that the sleeve can be coated on the periphery of the first end 31.
In addition, a limiting ring 34 is arranged between the first end 31 and the second end 32 of the transition part 3, the limiting ring 34 extends outwards along the radial direction, so that the first connecting part 2 and the second connecting part 4 can be separated, and the connecting cap 41 and the sleeve 23 are respectively abutted against two sides of the limiting ring 34.
Further, there is a possibility that the medicine leaks between the screw joint 5 and the threaded pipe 42, and thus the second coupling member 4 further includes a flow guide pipe 43, the flow guide pipe 43 being located at the outer periphery of the through-hole, the flow guide pipe 43 and the threaded pipe 42 forming an inner and outer double-layered pipe structure. The outer side wall of the threaded joint 5 is provided with an external thread and is in threaded connection with the threaded pipe 42, the inner side wall of the threaded joint is provided with a connecting cavity, the guide pipe 43 can be inserted into the connecting cavity and is in interference fit with the connecting cavity, medicines directly flow into the clinical joint connecting piece from the threaded joint 5 along the guide pipe 43, and the guide pipe 43 and the connecting cavity are in interference fit and can reduce leakage of the medicines.
In this embodiment, first connecting part 2 is provided with retainer plate 24 and sleeve 23, and retainer plate 24 links to each other with transition part 3 through the joint mode, and sleeve 23 increases the frictional force between first connecting part 2 and the transition part 3 through the mode of cladding to it is more firm to make to be connected between transition part 3 and the first connecting part 2, also can avoid the medicine to leak simultaneously. In addition, the second connection member 4 is provided with the flow guide tube 43 which is in interference fit with the threaded joint 5, and also has the effects of increasing the connection strength and avoiding medicine leakage.
