Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to a plug-opener. Background Art

[0002] Commonly used disposable plastic blood bags include triple bags, quadruple bags, and quintuple bags. For example, a quadruple bag consists of a whole blood collection bag, a red blood cell storage bag, a maintenance fluid bag, and a transfer bag. The bag bodies are connected by a plastic hose. A breakaway stopper is located at the junction of the bag and hose to isolate the bags and hoses before blood component preparation. During blood component preparation, the breakaway stoppers are opened sequentially according to the preparation process. In daily work, workers often manually break the stoppers to connect the blood bags. However, the stoppers are firmly connected, requiring repeated twisting to open them. This exerts force on the thumb joint, which can damage the knuckles over time. In practice, a tool is needed to more easily open the stopper, replacing manual methods. Utility Model Content

[0003] In view of the problems existing in the prior art, the utility model discloses a plug opener, and the technical solution adopted is that a motor, a battery, and a main control module are arranged inside the handle, and a switch button is arranged on the outer surface of the handle. The switch button, motor, battery, and main control module are electrically connected. The motor is a DC reduction motor, and the battery supplies power to the motor and the main control module. After pressing the switch button once to start the motor, the main control module controls the motor to perform a linkage action of first forward rotation and then reverse rotation, and the rotation angle is not greater than 180 degrees. The motor is fixedly mounted on the end of the handle, and its rotating shaft rotates through the handle and is fixedly connected to the plug opener through a coupling, thereby facilitating the disassembly, cleaning and disinfection of the plug opener. The tail of the handle is fixedly connected to a lifting rope for easy carrying. The outside of the handle is covered with a protective cover, which protects the whole and prevents it from falling and bumping. At the same time, it is convenient to remove it for cleaning and disinfection to ensure the cleanliness of the handle.

[0004] As a preferred solution of the present invention, the plug breaking head is a U-shaped structure with a snap groove in the middle. The width of the snap groove is 0.8 cm, and the width of the two side plates of the snap groove is 1 cm and the length is 2 cm, so that it is convenient to snap on a conical foldable blocking piece with a length of 2 cm and a diameter of 0.6-0.8 cm. Anti-slip edges are provided on both sides of the snap groove to increase the friction between the plug and the foldable blocking piece, ensuring that the breaking operation is easier to complete and avoid slipping.

[0005] The beneficial effects of the present invention are as follows: the present invention is designed with a plug-breaking head that is easy to snap onto the easily foldable blocking piece. After pinching the easily foldable blocking piece with the hand and snapping the plug-breaking head, the plug-breaking head is driven by the motor to rotate, so that the plug-breaking head performs a linked rotation action of first rotating forward and then reversed. The easily foldable blocking piece is grasped and fixed by the hand, and the easily foldable blocking piece is twisted and pried open to complete the plug-breaking work. By using the electric drive to generate force, there is no need to use both hands to twist the easily foldable blocking piece, which makes the work more time-saving and labor-saving and avoids damage to the finger joints. The plug-breaking head is fixedly connected to the motor shaft by a coupling, which facilitates the disassembly of the plug-breaking head for disinfection and cleaning, and is easy to use.

[0009] Example 1

[0010] like Figures 1 to 2 As shown, a plug-opening device of the present invention is provided with a motor 6, a battery 7, and a main control module 8 inside the handle 1. A switch button 2 is provided on the outer surface of the handle 1. The switch button 2, the motor 6, the battery 7, and the main control module 8 are electrically connected. The motor 6 uses a DC reduction motor, and the battery 7 supplies power to the motor 6 and the main control module 8. After the switch button 2 is pressed once to start the motor 6, the main control module 8 controls the motor 6 to rotate forward first and then reverse in a linked manner, and the rotation angle is not greater than 180 degrees. The motor 6 is fixedly mounted on the end of the handle 1, and its shaft rotates through the The handle 1 is fixedly connected to the plug breaking head 5 through the coupling 4, so as to facilitate the disassembly, cleaning and disinfection of the plug breaking head 5. The plug breaking head 5 is a U-shaped structure with a snap groove 501 in the middle. The width of the snap groove 501 is 0.8 cm, and the width of the two side plates of the snap groove 501 is 1 cm and the length is 2 cm, so as to facilitate snapping on a conical foldable blocking piece with a length of 2 cm and a diameter of 0.6-0.8 cm. Anti-slip edges 502 are provided on both sides of the snap groove 501, so as to increase the friction between the plug breaking head and the foldable blocking piece, ensuring that the breaking operation is easier to complete and avoid slipping.

[0011] The motor 6 drives the plug-breaking head 5 to rotate back and forth alternately in forward and reverse directions. The main control module 8 can set the rotation of the motor 6 to first rotate forward 90 degrees, then reverse 180 degrees, and then rotate forward 90 degrees again, thereby returning the plug-breaking head 5 to its original position, completing a plug-breaking operation, thereby twisting the easily foldable blocking member to open it. The handle 1 is fixedly connected to the tail end with a lifting rope 3 for easy carrying. The handle 1 is covered with a protective cover to protect the entire handle from falling and bumping, and is easy to remove for cleaning and disinfection to ensure the cleanliness of the handle 1.
