Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an automatic diversion device for medical columnar waste. Background Technology

[0002] Needles and syringes are indispensable medical sharps in healthcare institutions. Syringes are typically used for dispensing medication or injecting into the human body, and their heads have sharp needles. Needles are glass blood collection tubes with sharp edges. These specialized blood collection tubes are widely used in clinical testing, hematological examinations, biochemical analysis, and other medical activities, playing a vital role in ensuring the smooth operation of medical testing. With the increasing demand for medical testing, the use of syringes and needles continues to grow. Used syringes and needles are medical waste. Due to direct contact with blood, they pose a high risk of infection and require strict handling to avoid injury and infection.

[0003] Chinese patent document (publication number: CN208426219U) discloses a sharps container, a sharps container base, and a sharps container assembly. The sharps container provided by this utility model features a double-layer structure with a first and second cylindrical body, effectively improving the mechanical strength of the container and preventing it from being punctured by sharps, thus enhancing safety. A mounting cavity can be provided between the first and second cylindrical bodies to facilitate the installation of a lifting rod, a first connecting rod, and a second connecting rod. The lifting handle is located at the bottom of the second cylindrical body, preventing accidental activation of the switch controlling the opening and closing of the sharps container when it is closed or in its placed state, thus avoiding accidental opening. Simultaneously, the linkage design of the lifting rod and connecting rods makes it difficult to open the baffle through any part other than the lifting handle when the baffle is closed over the inlet, providing good self-locking and high safety. The sharps container base provided by this utility model allows the sharps container to be placed stably within the placement cavity; the increased height of the sharps container makes it more convenient for medical personnel to dispose of sharps. The first cylinder houses the bottom of the sharps container, and the second cylinder accommodates the lifting handle that extends out of the lifting cavity after the baffle is opened. The sharps container assembly provided by this invention uses the aforementioned sharps container and base to handle sharps waste, providing stable storage of sharps waste, good self-locking effect, and high safety in use; it also facilitates the disposal of sharps waste and reduces the workload of medical personnel.

Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an automatic diversion device for medical cylindrical waste. By alternating the left and right falling channels of syringes or tubes through the guide structure inside the box, the device automatically and evenly arranges them horizontally, making full use of the storage bin space and avoiding the safety hazards caused by the tip being upside down.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An automatic diversion device for medical columnar waste includes a lid installed on top of a collection bin for collecting columnar waste. A box body is fixedly connected to the top of the lid. The box body has a cavity structure, with arc-shaped plates on both sides of the top of the box body. A first channel is formed between the bottoms of the two arc-shaped plates. The first channel extends downwards and branches symmetrically to form two second channels. A throwing port is opened at the top of the box body, communicating with the top of the box body. The bottom ends of the two second channels penetrate downwards and communicate with the interior of the collection bin. A fixed shaft is installed at the connection between the first and second channels, and a guide body is rotatably installed on the fixed shaft. The guide body guides the columnar waste in the first channel to alternately fall into the collection bin through the two second channels on both sides.

[0008] As a preferred technical solution of this utility model, the guide body is a triangular prism, which is a stretched triangular structure. The apex of the triangle of the guide body abuts against the bottom inner wall of the first channel. An arc groove is opened in the middle of the base of the triangle to change the center of gravity of the guide body. When the guide body is squeezed, it quickly adjusts its tilt.

[0009] As a preferred technical solution of this utility model, a V-shaped needle unloading groove is provided on the side of the throwing port, and the V-shaped needle unloading groove is connected to the top of the box body.

[0010] As a preferred technical solution of this utility model, a box cover is provided on the top of the box body, an outer sealing ring is provided at the top of the box body, and an inner sealing ring adapted to the outer sealing ring is provided at the bottom of the box cover; protruding tongues are provided on both sides of the box body, and grooves adapted to the protruding tongues are provided on the bottom sidewall of the box cover.

[0011] As a preferred technical solution of this utility model, the lid and the box body are connected by a strap, and the strap is made of flexible plastic.

[0014] As a preferred technical solution of this utility model, the outer wall of the storage bucket is provided with scale lines for observing the amount of waste collected.

[0015] As a preferred technical solution of this utility model, a buffer pad is provided at the contact point between the triangular vertex of the guide body and the inner wall of the bottom of the first channel to reduce the impact when the guide body rotates.

[0016] As a preferred technical solution of this utility model, a flange is provided on the outer side of the top of the storage bucket, and a buckle adapted to the flange is provided on the inner wall of the bucket lid.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. This utility model forms a diversion system by setting a triangular prism-shaped guide body, a first channel, and a second channel inside the box. When medical waste is put into the dispensing port, it first passes through an arc plate to automatically adjust its position, and then enters the first channel, sliding along the inclined surface of the guide body. Due to the arc groove opened on the bottom edge of the guide body, the center of gravity is changed, so that it generates an eccentric force under the action of the gravity of the waste and automatically rotates back and forth, realizing the even distribution of waste on both sides of the collection bin; it also avoids the situation where the pointed end of columnar waste (such as a tube) is facing upward, reducing the difficulty of subsequent collection for staff; this utility model adopts a pure mechanical structure design, requires no electric drive, has a simple and reliable structure, and a low failure rate.

[0027] Figures 1-4 As shown, an automatic diversion device for medical columnar waste includes a lid 12 installed on the top of a collection bin 11. The collection bin 11 is used to collect columnar waste. The top of the lid 12 is fixedly connected to a box body 13. The box body 13 has a cavity structure. Arc-shaped plates 22 are provided on both sides of the top of the box body 13. A first channel 18 is formed between the bottoms of the two arc-shaped plates 22. The first channel 18 extends downward and branches symmetrically to form two second channels 21. A throwing port 16 is opened on the top of the box body 13. The throwing port 16 communicates with the top of the box body 13. The bottom ends of the two second channels 21 penetrate downward and communicate with the interior of the collection bin 11. A fixed shaft 20 is installed at the connection between the first channel 18 and the second channel 21. A guide body 19 is rotatably installed on the fixed shaft. The guide body 19 guides the columnar waste in the first channel 18 to fall alternately into the collection bin 11 through the two second channels 21 on both sides.

[0028] As indispensable medical sharps in medical institutions, basalt tubes and syringes are discarded after use. Their overall structure is cylindrical, and they are collectively referred to as cylindrical waste in this application.

[0029] In this invention, the used cylindrical waste is placed into the throwing port 16. The cylindrical waste automatically adjusts its position on the arc-shaped plate 22 and finally falls down into the first channel 18. The cylindrical waste slides along the inclined surface of the guide body 19. Due to the center of gravity design, the guide body 19 is easy to rotate. As the cylindrical waste falls through the second channel 21 on one side, the second channel 21 on the other side opens to receive the next cylindrical waste. This automatic reciprocating rotation mechanism achieves even distribution of cylindrical waste on both sides of the collection bin 11, avoiding one-sided accumulation. It also avoids the situation where the pointed end of the cylindrical waste (such as a tube) is facing upwards, reducing the difficulty of subsequent collection for workers. It adopts a purely mechanical structure design, requires no electric drive, has a simple and reliable structure, and a low failure rate.

[0030] Furthermore, the guide body 19 is a triangular prism, which is a stretched triangular structure. The apex of the triangle of the guide body 19 abuts against the bottom inner wall of the first channel 18. An arc groove is opened in the middle of the base of the triangle to change the center of gravity of the guide body 19. When the guide body 19 is squeezed, it quickly adjusts its tilt.

[0031] Figure 2 , Figure 3 As shown, the guide body 19 is a triangular stretched structure, installed at the bottom of the first channel 18 via a fixed shaft 20. An arc-shaped groove is opened in the middle of the base of the triangle to change the center of gravity. When the columnar waste falls from the first channel 18, it first slides along the inclined surface of the guide body 19. Due to the center of gravity design, the guide body 19 is easy to rotate. The gravity of the columnar waste acts on the side of the triangle to generate an eccentric force, driving the guide body 19 to rotate around the fixed shaft 20. The apex of the triangle of the guide body 19 gradually turns to the other side, so that while the current columnar waste falls through the second channel 21 on one side, the second channel 21 on the other side opens to receive the next columnar waste. Through this automatic reciprocating rotation mechanism, the columnar waste is evenly distributed on both sides of the collection bin 11, avoiding one-sided accumulation and improving space utilization. It also avoids the pointed end of the columnar waste (such as a tube) pointing upwards, reducing the risk of staff being scratched during subsequent sorting.

[0032] Furthermore, a V-shaped needle unloading groove 17 is provided on the side of the throwing port 16, and the V-shaped needle unloading groove 17 is connected to the top of the box body 13.

[0033] Figure 2As shown, the V-shaped needle removal groove 17 is used to remove the needle from a medical syringe. Its V-shaped structure design has a dual function: on the one hand, the inclined surface of the V-shaped groove can fix the syringe and prevent it from sliding during needle removal; on the other hand, the V-shaped structure can accurately align the connection between the needle and the syringe. When medical personnel need to remove the needle, they place the syringe into the V-shaped needle removal groove 17. Utilizing the fixing and guiding effect of the V-shaped structure, the needle is easily separated from the syringe. After separation, the needle passes through the V-shaped needle removal groove 17 and the communication channel at the top of the box 13, through the first channel 18 and the second channel 21, and then enters the storage bin 11.

[0034] Furthermore, a lid 14 is provided on the top of the box body 13, an outer sealing ring 23 is provided on the top of the box body 13, and an inner sealing ring adapted to the outer sealing ring 23 is provided on the bottom of the lid 14; protruding tongues 25 are provided on both sides of the box body 13, and a groove 26 adapted to the protruding tongues 25 is provided on the bottom side wall of the lid 14.

[0035] Figure 2 As shown, when the lid 14 is placed on top of the box body 13, the outer sealing ring 23 at the top of the box body 13 and the inner sealing ring 24 at the bottom of the lid 14 fit tightly together, forming a sealed structure. Simultaneously, the protruding tabs 25 on both sides of the box body 13 engage with the grooves 26 on the bottom sidewall of the lid 14, achieving reliable fixation through a snap-fit ​​mechanism. This dual protection mechanism ensures a stable connection and sealing effect between the lid 14 and the box body 13. It effectively prevents the leakage of viruses and bacteria from medical waste, reducing environmental pollution and the risk of cross-infection.

[0036] Furthermore, the lid 14 and the body 13 are connected by a strap 15, which is made of flexible plastic.

[0037] Figure 2 and Figure 4 As shown, the strap 15 is made of flexible plastic, with one end connected to the lid 14 and the other end connected to the box body 13. When the lid 14 needs to be opened, the flexible plastic strap 15 can bend and deform freely with the opening and closing of the lid, without affecting the normal opening of the lid 14. When the lid 14 is closed, the outer sealing ring 23 and the inner sealing ring 24, as well as the tongue 25 and the groove 26, can still maintain a good sealing and fixing effect. This prevents the lid from being lost or misplaced, ensures the continuity of the medical waste disposal process, and reduces the risk of cross-infection.

[0038] Furthermore, the storage bucket 11 and the box body 13 are made of transparent material, which is selected from any one of polycarbonate PC, polymethyl methacrylate PMMA, and polystyrene PS.

[0039] The transparency of the material allows medical staff to directly observe the internal operation of the device and the collection of waste. The transparent material ensures both the mechanical strength of the device and meets the needs of visual monitoring.

[0040] Furthermore, both the outer sealing ring 23 and the inner sealing ring 24 are made of elastic material, which is medical-grade silicone or EPDM rubber.

[0041] The outer sealing ring 23 and the inner sealing ring 24 are made of medical-grade silicone or EPDM rubber. Utilizing the excellent elastic deformation ability of these materials, the sealing rings will undergo moderate deformation when the lid 14 and the box body 13 are closed, filling the tiny gaps between the contact surfaces and forming a reliable sealing effect. When the lid is opened, the sealing rings can quickly return to their original shape, maintaining good elasticity and sealing performance.

[0042] Furthermore, the outer wall of the collection bucket 11 is provided with scale lines (not shown in the figure) for observing the amount of waste collected.

[0043] The collection bin 11 features graduated lines on its outer wall combined with transparent material, allowing medical staff to visually observe and measure the amount of waste collected inside. Once waste falls into the collection bin through the diversion system, the level indicated by the graduated lines can be used to promptly assess the bin's usage status.

[0044] Furthermore, a buffer pad (not shown in the figure) is provided at the contact point between the triangular vertex of the guide body 19 and the bottom inner wall of the first channel 18 to reduce the impact when the guide body 19 rotates.

[0045] When medical waste falls in and triggers the rotation of guide 19, the buffer pad absorbs and mitigates the impact force generated during rotation, reducing direct collisions between the vertices of the triangle and the inner wall of the channel. The buffer pad converts impact energy into deformation energy through its elastic deformation properties, thereby reducing the impact force between the contact surfaces.

[0046] Furthermore, a flange (not shown in the figure) is provided on the outer side of the top of the storage bucket 11, and a buckle (not shown in the figure) is provided on the inner wall of the lid 12 to match the flange. A sealing ring is provided at the connection between the storage bucket 11 and the lid 12 to seal and isolate the inside and outside, reducing the risk of cross-infection.

[0047] The flange on the outer top of the storage bucket 11 and the snap fastener on the inner wall of the lid 12 form a mechanical locking structure. When the lid 12 is closed, the snap fastener engages with the flange, achieving reliable fixation through the elastic deformation of the snap fastener. When opening, applying appropriate force can separate the snap fastener from the flange, allowing the lid to be removed.

[0048] This utility model is illustrated through the above embodiments, but it is not limited to these embodiments, meaning that it does not necessarily depend on them for implementation. Those skilled in the art should understand that all related improvements to this utility model fall within its protection and disclosure scope.
