Description

Technical Field

[0001] The present application relates to the technical field of medical equipment accessories, and specifically to a medical connector plug. Background Art

[0002] Medical connector plug is a connection device specially designed for use in medical equipment. It is used to ensure the stability of data transmission when the cable is connected to the medical equipment.

[0003] At present, two screws are symmetrically arranged on the connector plug in the prior art. After the connector is plugged into the socket of the medical device, the screws are turned to make one end of the screw threaded into the medical device to achieve the stability of the connection between the connector plug and the medical device. Although this structure can make the connector plug stably connected to the medical device, it takes a certain amount of time to turn the two screws when plugging and unplugging the plug. In addition, in the case of frequent plugging and unplugging, the screw connection may cause thread failure due to wear and even thread slippage. Utility Model Content

[0004] The purpose of the present application is to provide a medical connector plug to solve the technical problems raised in the above background technology.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0025] Example:

[0026] See also Figure 1-6 The present application provides a technical solution: a medical connector plug, comprising a plug-in body 1, a fastening connection unit 2 is arranged on the outer surface of the plug-in body 1, and the fastening connection unit 2 comprises an extension end 21 fixedly connected to the outer surface of the plug-in body 1, a slide groove 27 provided on the outer surface of the plug-in body 1, a slider 25 slidably connected in the slide groove 27, a guide rod 22 movably inserted inside the extension end 21, a spring 23 sleeved outside the guide rod 22, a connecting rod 24 fixed to the outer surface of the slider 25, and a clamping portion 26 rotatably connected to the outer surface of the plug-in body 1 (the clamping portion 26 is rotatably connected to the plug-in body 1 through a torsion spring);

[0027] One end of the guide rod 22 is fixedly connected to one side of the slider 25, and the two ends of the spring 23 are respectively connected to the extension end 21 and the slider 25. One side of the slider 25 lifts up one end of the clamping part 26 to press down the other end of the clamping part 26 to achieve clamping. One side of the slider 25 is provided with a slope 1 251, and one side of the clamping part 26 is provided with a slope 2 262 that matches the slope 1 251, and the other side of the clamping part 26 is integrally formed with a buckle 261. One side of the plug-in body 1 is provided with a pin 12 and a sealing pad 11 (to improve the sealing between the plug-in body 1 and the medical device connector).

[0028] By setting the above scheme, when the plug needs to be connected to the connector on the medical device, the sliding connecting rod 24 drives the slider 25 to move in the sliding groove 27, and the slider 25 slides in the direction of the extending end 21 to squeeze the spring 23. At this time, the inclined surface 1 251 is separated from the inclined surface 262, the clamping part 26 rotates and resets, and the end of the clamping part 26 adjacent to the slider 25 rotates in the direction of the plug-in body 1 (the force generated by the torsion spring drives the clamping part 26 to rotate and reset), so that the multiple buckles 261 are unfolded, and the end of the plug-in body 1 provided with the pin 12 is inserted into the connector of the medical device, and then the connecting rod 24 is released. The force generated by the spring 23 pushes the slider 25 to move in the direction of the clamping part 26, and the inclined surface 1 251 contacts the inclined surface 262. The slider 25 lifts one end of the clamping part 26, so that the multiple buckles 261 gather together, and the multiple buckles 261 are clamped on the connector of the medical device, thereby realizing the quick connection between the plug and the medical device.

[0029] See also Figure 2-Figure 4 In this embodiment, a through hole 13 and an active groove 14 communicating with the through hole 13 are provided inside the plug body 1, and a negative pressure locking unit 3 is also provided inside the plug body 1, and the negative pressure locking unit 3 includes a fixing plate 31 fixedly connected to the outer surface of one side of the plug body 1, a sleeve 32 integrally formed on the upper end of the fixing plate 31, an adjusting portion 33 screwed into the sleeve 32, and a piston 34 rotatably connected to the lower end of the adjusting portion 33 and located in the active groove 14. The fixing plate 31 is fixed to one side of the plug body 1 by bolts.

[0030] The inner wall of the sleeve 32 is fixedly connected with a threaded sleeve 35, and the adjusting part 33 includes a screw rod 333 screwed in the threaded sleeve 35, a hand-held end 331 fixedly connected to the upper end of the screw rod 333, and the lower end of the screw rod 333 is rotatably connected to the upper end of the piston 34. The outer surface of the hand-held end 331 is also fixedly connected with a sealing ring 332, and the outer surface of the sealing ring 332 is in contact with the inner wall of the sleeve 32.

[0031] By setting the above scheme, when the plug is connected to the medical device connector, due to the setting of the sealing gasket 11, a closed cavity is formed between the plug body 1 and the medical device connector. The handheld end 331 is rotated to drive the screw rod 333 to rotate. The screw rod 333 rotates inside the screw sleeve 35. The screw rod 333 can move upward inside the sleeve 32. The upward movement of the screw rod 333 can drive the piston 34 to move in the movable groove 14, so that negative pressure is formed between the through hole 13, the plug body 1 and the closed cavity between the medical device connector, so that the connection between the plug body 1 and the medical device connector is tighter, and the connection stability of the plug is better.
