Description

Technical Field

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

[0002] At present, patients use more indwelling needles when they receive infusion in hospitals to facilitate infusion and medication. During each infusion, the infusion set connected to the infusion bottle is connected to the indwelling needle left on the human body to perform the infusion. After each infusion, the infusion set needs to be separated from the indwelling needle.

[0003] The traditional method of separating the infusion set from the indwelling needle is usually for medical staff to pinch the infusion set and the indwelling needle with both hands respectively, and then rotate the two relative to each other to release the threaded fit before separating them. However, due to the small connection part, although medical staff can pinch the infusion set and the indwelling needle, in most cases it is difficult to effectively separate them by hand, which is time-consuming and labor-intensive, and difficult to separate stably. Alternatively, they can use clamping tools to separate them, but traditional clamping tools are difficult to effectively match with indwelling needles, resulting in unreliable and low safety in the operation of the separation tools. As a result, it is difficult for medical staff to ensure the safety and stability of the operation during separation, and it is even easy to pull the indwelling needle, causing harm to the patient.

[0050] Furthermore, after pressing the locking piece 16, the locking head 18 compresses the first spring 24 and enters the slot 23. At this time, the locking rod 17 extends into the guide slot 20, and then the positioning block 15 is kept pressed and pushed. The positioning block 15 drives the blade portion 1 to shrink along the receiving slot 8, and at the same time, the locking piece 16 drives the limit block 22 to slide along the chamber 19, and then the locking rod 17 of the locking piece 16 is moved to the next clearance hole 21. Then, the locking piece 16 is released, and under the elastic force of the first spring 24, the locking head 18 is pushed to insert into the clearance hole 21, and then the limit block 22 is fixed in the chamber 19. At the same time, the blade portion 1 is fixed in the receiving slot 8 of the handle portion 2 through the positioning block 15. The operation and adjustment are more flexible and convenient, which is conducive to improving the convenience of multi-functional use by medical staff.

[0051] In some embodiments of the multifunctional tool shears, a limit plate 25 is slidably installed in the chamber 19, the head end of the limit plate 25 is fixedly installed on the limit block 22, the outer surface of the limit plate 25 is in contact with one end of the clamping rod 3, and a limit protrusion 26 is formed in the middle of the limit plate 25, and the clamping rod 3 can slide to or slide the limit protrusion 26;

[0053] In these embodiments, the limiting protrusion 26 smoothly transitions to the two sides of the limiting plate 25. Through the cooperation between the limiting protrusion 26 and the clamping rod 3, as the limiting block 22 drives the limiting plate 25 to move, the clamping rod 3 is gradually pushed out of the shank portion 2. At this time, the second spring 27 is compressed until the clamping rod 3 slides to the limiting protrusion 26, and the clamping rod 3 is completely pushed out and fixed (at this time, the locking member 16 moves to the corresponding clearance hole 21, and the limiting plate 25 is fixed by the locking member 16), and then they are separated for use to ensure the safety and stability of the clamping and fixing of the clamping rod 3.

[0054] In some embodiments of the multifunctional tool shears, a receiving groove 28 is provided at the rear end of the handle portion 2, and the bottle opener 11 is slidably installed in the receiving groove 28;

[0055] A push rod 29 is slidably installed in the chamber 19, one end of the push rod 29 passes through the chamber 19 and extends into the receiving groove 28, and one end of the push rod 29 is fixedly connected to the bottle opening portion 11;

[0056] A third spring 30 is sleeved on the outer annular surface of the push rod 29 , one end of the third spring 30 is fixedly mounted on the push rod 29 , and the other end of the third spring 30 is fixedly mounted in the chamber 19 .

[0057] In these embodiments, by providing the receiving groove 28, the bottle opener 11 can be safely stored when not in use, thereby avoiding inconvenience to the use of other functions.

[0058] Through the cooperation of the push rod 29 and the third spring 30, the bottle opener 11 can be driven to extend into or out of the receiving groove 28 quickly and stably as the push rod 29 moves, and the bottle opener 11 can be quickly reset through the third spring 30, making the adjustment and use more stable and efficient.

[0059] In some embodiments of the multifunctional tool shears, the rear end of the limiting plate 25 is fixedly connected to a top plate 31 , and the top plate 31 is located on a side of the clamping rod 3 close to the push rod 29 , and the top plate 31 can abut against the push rod 29 .

[0060] In these embodiments, after the top plate 31 abuts against the push rod 29, the limit plate 25 moves, driving the push rod 29 to extend out of the chamber 19, thereby driving the bottle opening portion 11 to extend out of the receiving groove 28, and then opening the ampoule bottle.

[0061] In some embodiments of the multifunctional tool shears, finger rings 32 are fixedly mounted on opposite back surfaces of the two blade portions 1 .

[0062] In these embodiments, the double-hole finger ring 32 is used to control the use of the handle 2 more stably and reliably, and a protective pad, such as a cotton pad, a rubber pad, etc., is installed in the finger ring 32, which can further improve the comfort of use and make it more convenient for medical staff to use frequently.

[0063] When the utility model is used, first, when the scissors function is used, the blade portion 1 is located at the initial position, that is, in the state of extending out of the handle portion 2, and then the handle portion 2 can be held to be used as scissors. At this time, the clamping rod 3 and the bottle opener 11 are both stored in the handle portion 2, avoiding inconvenience caused when using the scissors function.

[0064] Then, when using the utility model to separate the infusion set and the indwelling needle, the two locking pieces 16 are pressed at the same time and lowered on the positioning block 15, driving the locking rod 17 to extend into the guide groove 20, and then the two positioning blocks 15 are pushed to move along the handle portion 2 at the same time. After the locking rod 17 is moved to the next clearance hole 21, the positioning block 15 is released, and under the action of the first spring 24, the locking head 18 is driven to extend out of the card slot 23 and inserted into the clearance hole 21, and then the positioning block 15 is fixed at the clearance hole 21. At this time, as the limit block 22 drives the movement of the limit plate 25, the clamping rod 3 is pushed out of the handle portion 2 and fixed through the limit protrusion 26, and then the infusion set is clamped through the separation port 4 to complete the separation of the infusion set and the indwelling needle.

[0065] When it is necessary to open the ampoule bottle, the positioning block 15 is continued to be pushed on the above basis (at this time the top plate 31 just contacts the push rod 29), and the positioning block 15 is fixed at the next clearance hole 21 (its working principle is the same as the above principle). As the limit block 22 moves, the clamping rod 3 continues to slide on the limit plate 25 and gradually moves away from the limit protrusion 26. Then, under the action of the second spring 27, the clamping rod 3 automatically extends into the handle portion 2 to complete the collection of the clamping rod 3, and at the same time drives the top plate 31 to move in the chamber 19 through the limit plate 25, and then pushes the push rod 29 to extend out of the chamber 19, thereby extending the bottle opening portion 11 out of the accommodating groove 28, and then the handle portion 2 is held in the opposite direction to clamp the ampoule bottle in the bottle opening mouth 12 to complete the opening of the ampoule bottle.

[0066] When the scissors function is needed, the locking member 16 is pressed and the positioning block 15 is pushed until it is reset. Under the action of the third spring 30 , the bottle opener 11 can be quickly stored in the receiving groove 28 .

[0067] It should be noted that when the utility model is directly adjusted from the scissors function to the ampoule bottle opening function, it is only necessary to push the positioning block 15 to fix it directly in the corresponding clearance hole 21 (the specific process is the same as the above principle) to quickly realize the conversion between functions, and when using one of the functions, the other two functions are in a "hidden" state, thereby ensuring the stability of functional use and avoiding the inconvenience caused by other functions. The flexibility of use is higher, and the use functions of the utility model can be flexibly switched according to the use requirements, so as to better meet the multi-functional use requirements.
