Description

Technical Field

[0001] The present invention belongs to the field of medical devices, and further belongs to a sharps box auxiliary processing device for reducing occupational exposure to sharps injuries. Background Art

[0002] Occupational exposure refers to the situation where medical staff accidentally get their skin or mucous membranes contaminated by the patient's blood or body fluids during diagnosis, treatment, nursing, prevention, inspection, etc., or get their skin pierced by sharp objects such as needles, blades, and other sharp objects used on patients, which may lead to infection by pathogens. Due to the characteristics of medical work, sharps injuries are one of the most common factors for medical staff to be infected with blood-borne diseases. Sharps boxes are protective containers for storing medical sharps. Correct use of sharps boxes can effectively reduce the incidence of sharps injuries to operators.

[0003] Sharps and used needles are placed in a sharps box, and the amount of the sharps box exceeds the warning level by three-quarters or two-thirds. The sharps box is not replaced in a timely manner and is sealed only when it is full, resulting in some sharps being exposed at the placement port. This increases safety risks, and the lock of the sharps box cannot be closed. Moreover, during the transfer of the sealed sharps box, the blood remaining in the sharps may splash onto the joint between the sharps box and the sharps box lid and seep out of the joint, leading to the hospital-based transmission of blood-borne diseases.

[0009] The height from the lower surface of the middle support plate to the bottom of the sharp tool box body is the sharp tool box filling warning height. When the filling amount of the sharp tool box does not reach the sharp tool box filling warning height, the sharp tools and the upper surface of the lifting member form a sliding friction force. When the filling amount of the sharp tool box reaches the sharp tool box filling warning height, the sharp tools form gravitational potential energy on the lifting member.

[0015] Beneficial Effects

[0016] The present invention forms a pre-tightening system through the elastic plate, the extrusion rod, and the limit member support plate. When the sharp object in the sharp object box falls, the upper part of the lifting member tends to be vertically convex, and the sharp object forms a sliding friction force with the upper surface of the lifting member. When the amount of the sharp object box reaches the warning height of the sharp object box, the sharp object falls on the upper surface of the lifting member. Since the sharp object forms gravitational potential energy on the lifting member, the lifting member descends along the first cavity. Due to the rigidity of the lifting member, the inner connecting rod, the outer connecting rod, and the sliding member as a whole, the sliding member slides from one side below the middle support plate to the middle area below the middle support plate, and the vertical height of the outer connecting rod increases, so that the distance from the upper surface of the slide to the lower surface of the middle support plate increases. Since the slide is limited by the stacked sharp objects, the middle support plate is pushed to move upward, thereby The squeezing rod moves upward along the supporting rod, squeezing the elastic plate with a convex profile. The elastic plate becomes flat due to the rebound effect, covering the opening of the sharps box, prompting the medical staff to stop throwing sharps and assisting in timely replacement of the sharps box, which can avoid sealing the sharps box until it is full and exposing some sharps at the delivery port. The filling volume of the sharps box can be controlled to be less than the warning height of the filling volume of the sharps box, thereby avoiding sharp injuries caused by medical staff when using the sharps box. At the same time, due to the rebound effect of the elastic plate, the end support plate can be pushed open. Due to the effect of gravitational potential energy, the end support plate is in an expanded state as a whole, fixing the limit of the sharps that have reached the warning line, avoiding the splash of blood carried by the sharps from the connecting port of the sharps box when the seal of the sharps box is transferred, thereby reducing the hospital transmission of blood-borne diseases.

DETAILED DESCRIPTION

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] according to Figure 1-Figure 6 As shown, a sharps box auxiliary processing device for reducing occupational exposure to sharp injuries includes a support rod 2, which is arranged in a vertical line. An elastic plate 3 and an extrusion rod 4 are sleeved on the upper outer surface of the support rod 2. The elastic plate 3 and the extrusion rod 4 are symmetrical about the central axis of the support rod 2. The two ends of the elastic plate 3 are straight surface profiles with vertically arranged cross sections, and the middle part of the elastic plate 3 is a convex profile with a cross section. A hollow structure 401 is provided inside the upper end of the extrusion rod 4. The extrusion rod 4 is sleeved and connected to the upper outer surface of the support rod 2 through the hollow structure 401. The outer surface of the support rod 2 and the side wall of the hollow structure 401 form an interference fit, so that the static friction force formed between the outer surface of the support rod 2 and the side wall of the hollow structure 401 can support the weight of the extrusion rod 4 and the overall feature below the extrusion rod 4. When the vertical height of the outer connecting rod 112 increases, the sliding friction force formed between the outer surface of the extrusion rod 4 and the side wall of the hollow structure 401 can cause the extrusion rod 4 to move upward along the support rod 2.

[0026] In this embodiment, the length of the line connecting the two ends of the convex contour of the elastic plate 3 is a, the upper surface of the extrusion rod 4 is located below the line connecting the two ends of the convex contour of the elastic plate 3, and the longest lateral distance of the upper surface of the extrusion rod 4 is b, b>a. The above setting allows the extrusion rod 4 to squeeze the convex contour of the elastic plate 3 during the upward pushing process to increase the rebound force of the elastic plate 3.

[0027] In this embodiment, the lower surface of the extrusion rod 4 is tightly fitted with the upper surface of the middle part of the limit member 5, the limit member 5 is horizontally arranged, the limit member 5 is concave, and the limit member 5 is a deformable limit member 5. Since the end of the elastic plate 3 is limited by the inner side surface of the adjacent limit member 5, due to the rebound effect of the elastic plate 3, the outer surface of the end of the elastic plate 3 and the inner side surface of the adjacent limit member 5 form a pre-tightening force, and the limit member 5 is a deformable limit member 5. When the rebound effect of the elastic plate 3 increases, the limit member 5 compensates and deforms, which can change the state of the pre-tightening force formed by the outer surface of the end of the elastic plate 3 and the inner side surface of the adjacent limit member 5, and the elastic plate 3 is no longer limited by the limit member 5.

[0028] In this embodiment, the lower surface of the limit member 5 is tightly fitted with the upper surface of the support plate. The support plate includes a middle support plate 601, an end support plate 603, and a deformable connecting member 602. The middle support plate 601 is connected to the end support plate 603 through the deformable connecting member 602. The cross-section of the deformable connecting member 602 is a vertical arc trend. The support plates are arranged longitudinally, the plate body of the middle support plate 601 is arranged horizontally, and the two adjacent end support plates 603 are arranged vertically with a narrowing trend. Due to the action of gravitational potential energy, the end support plates 603 form a pre-tightening force with the outer surface of the adjacent elastic member.

[0029] In this embodiment, a slide 9 is provided below the middle support plate 601, and the slide 9 is arranged horizontally. The lower surface of the middle support plate 601 is connected to the slide 9 through an elastic connecting piece. A surrounding body 10 is provided at one end of the upper surface of the slide 9. The inner side surface of the surrounding body 10 and one end of the upper surface of the slide 9 form a cavity. The cavity is provided with two outlets, and the two outlets include a first outlet 10c and a second outlet 10d. The cavity includes a first cavity 10a and a second cavity 10b. The first cavity 10a is arranged vertically, and the first cavity 10a is located below the opening 102 of the sharp tool box, and the first outlet 10c is located at the upper end of the first cavity 10a. The first cavity 10a is connected with the outside through the first outlet 10c, and the second outlet 10d is located above the second cavity 10b. The second cavity 10b is connected with the outside through the second outlet 10d.

[0030] In this embodiment, a slide 11 is provided in the second cavity 10b. The slide 11 is located in a side area below the middle support plate 601. The slide 11 fits tightly against the upper surface of the slide 9. The slide 11 has an arc-shaped profile. Two connecting rods are connected to the slide 11. The slide 11 and the two connecting rods form a corner profile as a whole. The slide 11 is the corner of the corner profile. The two connecting rods include an inner connecting rod 111 and an outer connecting rod 112. The inner connecting rod 111 is located in the cavity. A lifting member 113 is provided at the end of the inner connecting rod 111. The lifting member 113 is located at the first outlet 10c. The first cavity 10a is closed by the lower part of the lifting member 113. The side contour of the lifting member 113 is consistent with the contour of the first outlet 10c. The above arrangement can prevent the sharp weapon 13 from falling into the cavity before the sharp weapon 13 reaches the warning line of the sharp weapon box, thereby hindering the movement of the whole formed by the slide 11 and the two connecting rods.

[0031] In this embodiment, the upper part of the lifting member 113 is in a vertical convex shape, the upper part of the lifting member 113 is located above the first outlet 10c, and the upper end of the lifting member 113 is located below the lower surface of the middle support plate 601. The above arrangement allows the sharp object 13 to contact the lifting member 113 and generate sliding friction when it falls, thereby avoiding the sharp object 13 acting on the lifting member 113 before it reaches the warning line of the sharp object box to generate gravitational potential energy, causing the movement form of the lifting member 113 to change.

[0032] In this embodiment, the outer connecting rod 112 is connected to the outside through the second outlet 10d, the angle formed by the outer connecting rod 112 and the slideway 9 is c, and the end of the outer connecting rod 112 is fixed to the lower surface of the middle support plate.

[0033] In this embodiment, the height from the lower surface of the middle support plate 601 to the bottom of the sharp tool box body 103 is the sharp tool box filling warning height. When the sharp tool box is filled with less than the sharp tool box filling warning height, the sharp tool 13 and the upper surface of the lifting member 113 form a sliding friction force. When the sharp tool box is filled with more than the sharp tool box filling warning height, due to space limitations, the sharp tool 13 and the upper surface of the lifting member 113 can no longer continue to generate sliding friction force. The sharp tool 13 forms gravitational potential energy on the lifting member 113. The lifting member 113 is located as a whole in the first cavity 10a. The angle formed by the outer connecting rod 112 and the slide 9 is d, d>c. Due to the principle of rigidity, the vertical height of the outer connecting rod 112 is increased, and the height from the lower surface of the middle support plate 601 to the upper surface of the slide 9 is increased. The surface distance increases. Since the amount of the sharps box has reached the warning height for the amount of the sharps box, the slide 9 is limited due to the accumulation of the sharps 13, so that the middle support plate 601 moves upward, and the elastic connector is in an extended state. The upper surface of the extrusion rod 4 is tightly attached to the lower surface of the elastic plate 3, and the elastic plate 3 is in a flattened state. The upper surface of the elastic plate 3 in the flattened state is located below the opening 102 of the sharps box. When the amount of the sharps box has not reached the warning height for the amount of the sharps box, the opening 102 of the sharps box is blocked, prompting medical personnel to stop throwing sharps 13 and assist in timely replacement of the sharps box. The cross-section of the deformable connector 602 is horizontal, and the support plate is in a supported state as a whole. The support plate in the supported state is arranged horizontally as a whole.

[0034] In this embodiment, the pre-tightening system is formed by the elastic plate 3, the extrusion rod 4, the limit member 5, and the expansion plate. When the sharp object 13 in the sharp object box falls, the upper part of the lifting member 113 tends to be vertically convex, and a sliding friction force is formed between the sharp object 13 and the upper surface of the lifting member 113. When the amount of the sharp object box reaches the sharp object box filling warning height, due to space limitations, the sharp object 13 falls on the upper surface of the lifting member 113, so that the sharp object 13 forms gravitational potential energy on the lifting member 113, and the lifting member 113 descends along the first cavity 10a. Due to the overall rigidity of the lifting member 113, the inner connecting rod 111, the outer connecting rod 112, and the sliding member 11, the sliding member 11 slides from one side below the middle expansion plate 601 to the middle area below the middle expansion plate 601, and the vertical height of the outer connecting rod 112 increases, so that the distance from the upper surface of the slide 9 to the lower surface of the middle expansion plate 601 increases. The limit pushes the middle opening plate 601 to move upward, thereby causing the squeezing rod 4 to move upward along the supporting rod 2, squeezing the elastic plate 3 with a convex profile, and the elastic plate 3 becomes flat due to the rebound effect, blocking the opening 102 of the sharps box, prompting the medical staff to stop throwing the sharps 13, and assisting in timely replacement of the sharps box, which can avoid sealing the sharps box until it is full and exposing part of the sharps 13 at the delivery port, and can control the filling volume of the sharps box to be less than the warning height of the filling volume of the sharps box, thereby avoiding sharp injuries caused by medical staff when using the sharps box. At the same time, due to the rebound effect of the elastic plate 3, the end opening plate 603 can be pushed open, and the end opening plate 603 is in an open state as a whole due to the effect of gravitational potential energy, fixing the limit of the sharps 13 that have reached the warning line, and avoiding the blood carried by the sharps 13 from splashing and seeping out from the connection port of the sharps box when the seal of the sharps box is transferred, thereby avoiding the hospital transmission of blood-borne diseases.

[0035] In this embodiment, the support rod 2 is located at the center of the lower surface of the sharps box cover 101, and the sharps box filling warning height accounts for 2 / 3-3 / 4 of the total filling volume of the sharps box.

[0036] In this embodiment, the elastic connecting member is an elastic rope 8, the amount of the sharps box has not reached the sharps box filling warning height, the length of the elastic rope 8 is e, the distance from the upper surface of the extrusion rod 4 to the lower surface of the highest point of the raised contour of the elastic plate 3 is f, the amount of the sharps box has reached the sharps box filling warning height, the length of the elastic rope 8 is g, ge≥f.

[0037] In this embodiment, a balance block 7 is provided at the other end of the upper surface of the slide 9. The balance block 7 has the same overall weight as the enclosure 10, the slide 11 and the two connecting rods. The end support plate 603 is made of polyvinyl chloride. The end support plate 603 is a material with a certain weight. When the support plate is not fully expanded, the end support plate 603 can form a pre-tightening force with the upper surface of the elastic plate 3 due to the gravitational potential energy. The overall edge contour of the expanded support plate is consistent with the edge contour of the inner wall of the sharp tool box. Since the end support plate 603 has a large gravitational potential energy, it can be tightly pressed on the sharp tool 13 to limit the sharp tool 13, thereby preventing the end support plate 603 from shaking up and down during the transfer of the sharp tool box, resulting in the sharp tool 13 not being limited by the support plate.

[0038] In this embodiment, the end of the outer connecting rod 112 is a convex arc surface, and the lower surface of the middle support plate where the end of the outer connecting rod 112 is fixed is a concave arc surface. The convex arc surface and the concave arc surface form a close-fitting pre-tightening force. The above arrangement can limit the end of the outer connecting rod 112 by the lower surface of the middle support plate 601, and when the angle formed by the outer connecting rod 112 and the slide 9 increases, the end of the outer connecting rod 112 remains in a fixed position when it is limited by the middle support plate 601.

[0039] This example works as follows:

[0040] 1. Installation: Place the sharps box cover 101 of this embodiment at the center of the lower surface through the support rod 2, so that the lifting member 113 is located directly below the sharps box opening 102, and the sharps box cover 101 and the sharps box body 103 are installed and fixed.

[0041] 2. When the sharps box packing quantity does not reach the sharps box packing quantity warning height during use: When the sharps 13 in the sharps box fall, due to the vertical convexity tendency of the upper part of the lifting member 113, the sharps 13 and the upper surface of the lifting member 113 form a sliding friction force, causing the sharps 13 to gradually accumulate.

[0042] 3. When the sharp weapon box load reaches the sharp weapon box load warning height during use: due to space limitations, the sharp weapon 13 and the upper surface of the lifting member 113 can no longer generate sliding friction, and the sharp weapon 13 forms gravitational potential energy on the lifting member 113, and the lifting member 113 as a whole descends into the first cavity 10a. The angle formed by the outer connecting rod 112 and the slide 9 increases. Due to the rigidity principle, the slide 11 slides from one side below the middle support plate 601 to the middle area below the middle support plate 601, and the vertical height of the outer connecting rod 112 increases, which increases the distance from the upper surface of the slide 9 to the lower surface of the middle support plate 601. Since the slide 9 is limited by the stacked sharp weapons 13, the middle support plate 601 is pushed upward, thereby causing the extrusion rod 4 to move along The support rod 2 moves upward, squeezing the elastic plate 3 with a convex profile. The elastic plate 3 becomes flat due to the rebound effect, blocking the opening 102 of the sharps box, prompting the medical staff to stop throwing the sharp weapon 13, assisting in timely replacement of the sharps box, and controlling the filling volume of the sharps box to be less than the warning height of the filling volume of the sharps box, thereby avoiding sharp injuries caused by medical staff when using the sharps box. At the same time, due to the rebound effect of the elastic plate 3, the end support plate 603 can be pushed open. Due to the effect of gravitational potential energy, the end support plate 603 is in an open state as a whole, fixing the limit of the sharp weapon 13 that has reached the warning line, avoiding the blood carried by the sharp weapon 13 from splashing and seeping out from the connection port of the sharps box when the sharps box is sealed and transferred, thereby reducing the hospital transmission of blood-borne diseases.
