TECHNICAL FIELD

[0001] The present application relates to the technical field of medical waste storage, in particular to a sharp box with a pipe twisting and cutting function. BACKGROUND

[0002] In clinical medical operations, sharp instruments such as infusion devices, blood bag pipes, etc. with pipes (such as needle, indwelling needle) need to be harmlessly treated. The traditional process requires medical staff to manually separate the needle and the pipe, such as manually pulling out or cutting with scissors. The advantage of separating the needle and the pipe is that the recycling personnel can use different treatment methods according to different materials. At the same time, since the cost of medical waste during recycling is calculated according to the weight, the pipe is usually separated from the needle and treated separately.

[0003] At present, when the traditional sharp box is used, the following disadvantages usually exist: 1. Manual operation can easily cause a needle stick injury, and according to statistics, 25% of needle stick injuries occur during the separation process. 2. During the manual cutting of the pipe, the pipe is elastic and there is air inside the pipe, which makes cutting difficult. Therefore, the current application requirements of hospitals cannot be met by using the method of stretching the pipe with both hands for cutting the ductile pipe. SUMMARY

[0004] The present application provides a sharp box with a pipe twisting and cutting function, which can twist the pipe to be cut, reduce the air in the cutting section in contact with the blade, and facilitate the blade to advance and cut after the ductile pipe is twisted together.

[0005] The purpose of the present application is achieved by the following technical solutions: The sharp box with a pipe twisting and cutting function comprises a cover body, a pipe clamping device and a pipe cutting device. The pipe clamping device comprises a rotating disc, a clamping block and a rotating seat. The rotating disc is rotatably installed on the cover body. The rotating seat is fixedly installed on the upper end of the rotating disc. The clamping block is rotatably installed on the rotating seat. The infusion pipe fixing clamp is arranged between the plurality of clamping blocks. The pipe cutting device comprises a cutting head and a driving member for driving the rotating disc to rotate. The cutting head is provided with a cutting blade. The cutting head is slidably arranged above the cover body.

[0006] Preferably, the driving member comprises a connecting rod, a rotating wheel and a driving rod. The rotating wheel is fixed on the rotating disc. One end of the connecting rod is fixed with the cutting head, and the other end is fixed with the driving rod. The driving rod and the rotating wheel are in meshing transmission.

[0007] Preferably, the pipe clamping device further comprises a fixed rod and a sliding rail. The fixed rod is fixed on the cover body. The sliding rail is fixed with the cutting head. The sliding rail is provided with a sliding groove matched with the fixed rod.

[0008] Preferably, the fixed rod is provided with a force receiving handle, and the slide rail is provided with a pushing handle.

[0009] Preferably, the fixed rod is provided with a support part, and the slide rail is in contact with the support part.

[0010] Preferably, a torsional spring is sleeved on the connecting shaft of the clamping block and the rotating seat, one end of the torsional spring is fixed to the clamping block, and the other end is fixed to the rotating seat.

[0011] Preferably, the pipeline clamping device further comprises a splash-proof assembly, the splash-proof assembly comprises a fixed block, an upper limiting plate, a lower limiting plate, an upper splash-proof ring and a lower splash-proof ring, the fixed block is fixed to the cover body, the upper limiting plate and the lower limiting plate are both fixed to the fixed block, and a gap suitable for the cutting head to slide through is left between the upper limiting plate and the lower limiting plate, the upper splash-proof ring is fixed to the upper limiting plate, and the lower splash-proof ring is fixed to the lower limiting plate.

[0012] Preferably, the side end of the fixed block is provided with a through groove suitable for the cutting head to pass through.

[0013] Preferably, a containing box for containing the sharp instrument is arranged below the cover body.

[0014] Compared with the prior art, the technical scheme of the present application has the following advantages or beneficial effects: 1. Non-contact integrated processing is realized, and the risk of medical care puncture is eliminated: by integrating the torsional cutting mechanism, the user only needs to insert the pipeline into the sharp instrument box and rotate, so that the pipeline cutting and sharp instrument separation (such as automatic falling of the needle into the box) can be completed synchronously in a single operation, without manual touching of the sharp instrument or use of auxiliary tools, and the occupational safety protection level is significantly improved.

[0015] 2. The cutting efficiency and reliability of the ductile pipeline are improved: by twisting the pipeline to be cut, the air inside the pipeline is discharged, thereby reducing the obstruction in the cutting process. At the same time, the ductile material pipeline is more conducive to the advancement of the cutting blade after being twisted. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0018] The embodiments of the present application will be described in detail below with reference to the accompanying drawings and examples, so that the implementation process of how the present application applies technical means to solve technical problems and achieves corresponding technical effects can be fully understood and implemented. The embodiments of the present application and each feature in the examples can be combined with each other without conflict, and the formed technical solutions are all within the protection scope of the present application.

[0019] It should be clear that the following described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application. EMBODIMENT

[0020] The present embodiment describes in detail the scheme of the sharp box with the function of twisting and cutting the pipeline: As shown in Figures 1-6 , the sharp box with the function of twisting and cutting the pipeline includes a cover 2, a pipeline clamping device, and a pipeline cutting device. The pipeline clamping device includes a rotating disc 18, a clamping block 19, and a rotating seat 20. The rotating disc 18 is rotatably installed on the cover 2. The rotating seat 20 is fixedly installed on the upper end of the rotating disc 18. The clamping block 19 is rotatably installed on the rotating seat 20. The infusion tube 1 is fixedly clamped between the plurality of clamping blocks 19. The pipeline cutting device includes a cutting head 10 and a driving member for driving the rotating disc 18 to rotate. The cutting head 10 is provided with a cutting blade 9. The cutting head 10 is slidably arranged above the cover 2. The driving member includes a connecting rod, a rotating wheel 15, and a drive rod 14. The rotating wheel 15 is fixed to the rotating disc 18. One end of the connecting rod is fixed to the cutting head 10, and the other end is fixed to the drive rod 14. The drive rod 14 and the rotating wheel 15 are in meshing transmission.

[0021] Among them, as shown in Figure 3 , the pipeline is pressed against by the clamping block 19. When the staff pushes the cutting head 10 towards the infusion tube 1, the cutting blade 9 on the cutting head 10 will gradually approach the infusion tube 1 until it is cut off.

[0022] In the above process, since the driving rod 14 and the cutting head 10 are fixed through the connecting rod, when the cutting head 10 moves towards the infusion tube 1, the driving rod 14 which synchronously slides with the cutting head 10 drives the rotating wheel 15 engaged with the driving rod 14 to rotate, that is, the infusion tube 1 is twisted. After the infusion tube is twisted, the air in the tube is discharged, and the pipeline is twisted together, which is convenient for being disconnected with the cutting blade 9 and being cut off.

[0023] In the embodiment, another advantage of the above-mentioned twisted and rotated infusion tube 1 is that when the infusion tube 1 is cut off, the liquid medicine and blood in the tube will flow out directly. When the infusion tube 1 returns to the state before deformation after being twisted, the liquid medicine and blood will be thrown out and flow into the sharp tool box. Since the cut-off infusion tube 1 has wrinkles and folds on the tube wall, even if there is some liquid left in the tube, it is not easy to flow out directly from the tube, thereby polluting the environment. (The liquid medicine and blood close to the needle end will fall into the containing box 3 after being cut) As shown in Figure 2 and Figure 3 , the pipeline clamping device further comprises a fixed rod 22 and a sliding rail 13. The fixed rod 22 is fixed on the cover 2, and the sliding rail 13 is fixed with the cutting head 10. The sliding rail 13 is provided with a sliding groove 12 matched with the fixed rod 22. The fixed rod 22 is provided with a force receiving handle 11, and the sliding rail 13 is provided with a pushing handle 4. The fixed rod 22 is provided with a supporting portion, and the lower part of the sliding rail 13 is attached to the supporting portion.

[0024] The staff can hold the pushing handle 4 and the force receiving handle 11, and during the process of holding tightly, the distance between the pushing handle 4 and the force receiving handle 11 is close, so that the cutting head 10 moves towards the side of the infusion tube 1.

[0025] In the embodiment, the connecting shaft of the clamping block 19 and the rotating seat 20 is sleeved with a torsional spring 21. One end of the torsional spring 21 is fixed with the clamping block 19, and the other end is fixed with the rotating seat 20. The torsional spring 21 provides elasticity for the clamping block 19, so that the clamping block 19 always moves towards the side close to the infusion tube 1. Embodiment

[0026] As shown in Figure 3 , the pipeline clamping device further comprises a splash-proof assembly. The splash-proof assembly comprises a fixed block 5, an upper limiting plate 7, a lower limiting plate 17, an upper splash-proof ring 8 and a lower splash-proof ring 16. The fixed block 5 is fixed on the cover 2. The upper limiting plate 7 and the lower limiting plate 17 are both fixed on the fixed block 5. A gap matched with the sliding of the cutting head 10 is left between the upper limiting plate 7 and the lower limiting plate 17. The upper splash-proof ring 8 is fixed with the upper limiting plate 7, and the lower splash-proof ring 16 is fixed with the lower limiting plate 17. The side end of the fixed block 5 is provided with a through slot 6 matched with the cutting head 10. The lower part of the cover 2 is provided with a containing box 3 containing sharp tools.

[0027] The upper anti-splashing ring 8 and the lower anti-splashing ring 16 prevent the cut twisted infusion tube 1 from splashing the residual liquid in the tube to the operator during the deformation recovery process. After the tube is cut, the staff can push the cut tube end downward or use a special rod to push the cut needle into the containing box 3.

[0028] Example 3: Handling of blood-containing infusion tube after hemodialysis treatment Scenario: A hemodialysis nurse needs to handle a 1.5-meter silicone infusion tube connected to a 16G puncture needle (containing anticoagulant blood in the tube).

[0029] Operation process: Clamping the tube: press the clamp block 19 (the torsion spring 21 provides self-locking force) to clamp the tube at the root of the needle between the three clamp blocks 19, and the needle is suspended above the cover 2.

[0030] Pushing the cutting: hold the pushing handle 4 and the force receiving handle 11 with one hand and press them towards the center → drive the cutting head 10 to slide along the sliding groove 12, synchronously drive the driving rod 14 (through the meshing rotating wheel 15) to make the rotating disc 18 rotate 180° → the tube is twisted and tightly bundled (the internal air is extruded, and the silicone tube wall is folded and overlapped).

[0031] Synchronous cutting: the cutting head 10 continues to move forward, and the blade 9 completes the cutting at the twisted section of the tube (the needle falls into the containing box 3), and the residual blood is splashed into the range of the lower anti-splashing ring 16 by the twisting rebound force.

[0032] Anti-pollution closed loop: the cutting debris is blocked by the upper / lower anti-splashing rings 8 / 16, and there is no blood splashing; the cut exposed tube (about 8 cm long) is pushed down and falls into the containing box 3 through the through slot 6 and is sealed together with the needle.

[0033] Innovation value: Avoid blood splashing caused by traditional cutting method of pulling with both hands (arterial pressure risk).
