Description

Technical Field

[0001] The utility model relates to the technical field of tweezers, in particular to a pair of medical nursing tweezers. Background Art

[0002] Medical nursing tweezers are a common medical device tool used to clamp drugs. Traditional tweezers are usually made as a whole. Tweezers with different tweezer heads are needed in different environments. They need to be replaced frequently during use, occupying a large space and being inconvenient to use. Once the tweezer heads, which are most easily worn during use, are damaged, the entire pair of tweezers will be scrapped, resulting in high cost of use and waste. Different tweezers are needed to clamp different drugs, especially smaller granular drugs. For drugs with lower hardness, when the clamping force is too large, it is easy to cause the drugs to wear or even break, resulting in drug waste. Utility Model Content

[0003] Therefore, in view of the above problems, the utility model provides a pair of medical nursing tweezers, which solves the technical problems that the existing medical nursing tweezers are inconvenient to use and may damage the medicine.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A pair of medical nursing tweezers, comprising a fixed handle and a movable handle, the fixed handle and the movable handle are hinged, the fixed handle and the movable handle extend forward to form a clamping rod, the other ends of the two clamping rods are connected to a tweezer head, the end of the clamping rod is provided with a slot, one end of the tweezer head is provided with a plug-in, the plug-in can be inserted into the slot, the plug-in is telescopically provided with at least one positioning marble, the slot is provided with a through opening corresponding to the positioning marble, the surface of the tweezer head is provided with at least two clamping parts of different shapes, an elastic device is provided between the fixed handle and the movable handle, the elastic device comprises a first elastic sheet connected to the fixed handle and a second elastic sheet connected to the movable handle, the first elastic sheet is provided with a slide groove, the second elastic sheet is provided with a slider, the slider extends out of the slide groove surface, the slider can slide along the slide groove, and the first elastic sheet and the second elastic sheet can be bent.

[0006] Further:

[0007] When the angle between the fixed handle and the movable handle is a first angle, the slider moves to the end of the slide slot. When the angle between the fixed handle and the movable handle is less than the first angle, the first elastic sheet and the second elastic sheet bend and deform. The first angle is 30 to 45 degrees.

[0008] The sliding block is spherical.

[0009] The number of the positioning marbles is two, and the two positioning marbles are respectively arranged on both sides of the plug-in.

[0010] The clamping portion has two shapes, one of which has a grid-shaped surface and the other has a plurality of spherical protrusions on its surface.

[0011] The fixed handle is provided with a protruding hand rest portion.

[0012] A silicone anti-skid pad is arranged on the movable handle.

[0013] The clamping rod is provided with an LED lamp, the fixed handle or the movable handle is provided with a lighting switch, and the LED lamp and the lighting switch are electrically connected.

[0014] By adopting the above technical solution, the beneficial effects of the utility model are:

[0015] The utility model provides a plurality of clamping parts of different shapes on the tweezers head, which is convenient for clamping medicines of different structures. When the clamping part needs to be replaced, the tweezers head can be rotated until the positioning marble is stuck in the through hole. At this time, the clamping part is rotated to the corresponding position and fixed, so that the medicine can be clamped. If the tweezers head does not have the clamping part required by the user, the tweezers head can be removed as a whole and replaced with other tweezers heads. The tweezers head is easy to use, has rich functions and high versatility, and the elastic device plays a certain buffering role, which can prevent the medicine from being worn or even damaged due to excessive force. The utility model has a simple structure and is easy to operate, and is suitable for popularization and application. Furthermore, the fixed handle and When the angle between the movable handles is less than a certain angle, the slider will no longer move. The user continues to use force to bring the fixed handle and the movable handle closer. At this time, the first elastic sheet and the second elastic sheet will bend appropriately. In this structure, the smaller the angle, the greater the reverse force applied to the hand, which can prevent the clamping force from being too large to cause wear or damage to the drug, and reduce the risk of damage to the drug during the clamping process; further, the two clamping parts of different shapes can be used to clamp different drugs; further, the hand rest and the silicone anti-slip pad can prevent the hand from slipping, thereby improving the comfort and durability of use; further, the LED light makes it easier to use in a dim environment.
