Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical instruments, in particular to a shearing device for being installed on a sharps barrel. Background Art
[0002] Traditional sharps buckets have disadvantages:
[0003] (1) The traditional sharps bucket is complex in handling sharps;
[0004] Traditional sharps bins do not have cutting devices, and are difficult to handle sharps of different sizes and shapes. For example, when dealing with scalp needles, it is often necessary to find a separate cutting tool. This cutting method is more cumbersome and requires more work to work effectively, resulting in inconvenient operation and even low efficiency.
[0005] (2) Traditional sharps buckets pose a risk of sharps injuries
[0006] Data from the Exposure Prevention Information Network shows that sharps injuries are most common in operating rooms and wards, and nurses are the most vulnerable group. The risk of sharps injuries among interns is also increasing. Moreover, sharps buckets, as sharps containers, are more likely to cause injuries when handling sharps, increasing the risk of occupational exposure. According to surveys, medical workers have a higher rate of HBV, HCV and HIV infection. After being stabbed by HBsAg-positive patients, HBV transmission ranges from 6% to 30%;
[0007] Therefore, a device is expected to facilitate shearing of sharp objects while avoiding needle stick injuries to medical staff as much as possible. Utility Model Content
[0008] The purpose of the utility model is to provide a shearing device for installation on a sharps barrel in view of the problems and shortcomings described in the background technology.
[0009] A shearing device for mounting on a sharps barrel, comprising a clamp band, a bolt, a scissors, a hinge shaft, a spring, a baffle and an opening;
[0010] The clamp band is sleeved on the outer ring of the sharp instrument barrel cover, and the opening side of the clamp band is connected by bolts. A baffle is connected to the clamp band away from the opening side, and the baffle is arranged at the upper end of the sharp instrument barrel cover. An opening that can be connected to the interior of the sharp instrument barrel is arranged on the baffle, and the opening is arranged in an inverted cone structure. The scissors are hinged to the baffle through a hinge shaft, and a groove with convex teeth is provided between the working ends of the two scissor blades, and a spring is connected between the handle ends of the two scissor blades.
[0011] Beneficial effects of the utility model:
[0012] When used to cut the needle hose, hold the tube body and put the needle part into the opening, extend it downward for a distance, and press the scissors with the other hand. At this time, the spring is compressed and the needle hose is cut off. Since the opening is small and the opening is in an inverted cone structure, it is convenient for the needle hose to enter and not conducive to the needle hose to tilt. When the needle hose is inserted into the opening, the lower end of the needle hose has entered the sharps barrel. After being cut off at this time, it will not curl or tilt under the tension of the needle hose, thereby avoiding needle stick injuries to medical staff;
[0013] A spring is also installed on the scissors, which can automatically rebound after use, avoiding the need for medical staff to open the scissors every time they use them. This product can be disassembled and reused to ensure the sustainable development of the social economy. BRIEF DESCRIPTION OF THE DRAWINGS
[0014] Figure 1 It is a three-dimensional schematic diagram of the utility model;
[0015] Figure 2 This is a diagram of the use state of the utility model installed on a sharps bucket. DETAILED DESCRIPTION
[0016] Referring to the accompanying drawings, a shearing device for installation on a sharps barrel includes a clamp band 1, a bolt 2, a pair of scissors 3, a hinge shaft 4, a spring 5, a baffle 6 and an opening 7;
[0017] A clamp band 1 is sleeved on the outer ring of the sharp instrument barrel cover, and the opening side of the clamp band 1 is connected by a bolt 2. A baffle 6 is connected to the clamp band 1 away from the opening side, and the baffle 6 is arranged at the upper end of the sharp instrument barrel cover. An opening 7 that can be connected to the interior of the sharp instrument barrel is provided on the baffle 6, and the opening is arranged in an inverted cone structure. The scissors 3 are hinged to the baffle 6 through a hinge shaft 4, and a groove 9 with convex teeth is provided between the working ends of the two scissor blades, and a spring 5 is connected between the handle ends of the two scissor blades.
[0018] Preferably, a protective cover 8 is also included, which is arranged on the baffle 6. The protective cover 8 is used to block the working path of the working end of the scissors 3 to prevent the working end of the scissors 3 from scratching medical staff.
[0019] The working principle of this utility model:
[0020] This product uses a new type of shearing device, which is added on the basis of the original sharps barrel, without changing the original sharps barrel, thus reducing costs;
[0021] When in use, it is only necessary to put the clamp band 1 on the outer ring of the original sharps bucket cover and turn the bolt 2 to tighten it. When the sharps bucket is full, the shearing device can be disassembled to meet the requirements of repeated use.
[0022] When the utility model is used to shear the needle hose, the user holds the hose body and puts the needle part into the opening 7, extends it downward for a distance, and presses the scissors 3 with the other hand. At this time, the spring 5 is compressed and the needle hose is sheared off. Since the opening 7 is small and has an inverted cone structure, it is convenient for the needle hose to enter and not conducive for the needle hose to tilt. When the needle hose is inserted into the opening 7, the lower end of the needle hose has entered the sharps barrel. After being sheared off at this time, it will not curl or tilt under the tension of the needle hose, thereby avoiding needle stick injuries to medical staff.
[0023] If it is necessary to separate the syringe and the needle on the syringe, the medical staff only needs to move the upper edge of the syringe needle close to the groove 9, and manually press the scissors 3. At this time, the spring 5 is compressed, the syringe needle is clamped, and the medical staff unplugs the syringe with the other hand to separate them, thereby avoiding accidents of sharp objects piercing the nursing staff's hands and causing the spread of blood-borne diseases.
[0024] In addition, a spring 5 is installed on the scissors 3, which can automatically rebound after use, avoiding the need for medical staff to open the scissors 3 each time they use them. This product can be disassembled and reused to ensure the sustainable development of the social economy.
[0025] The technical problem to be solved by the utility model is: on the basis of not changing the original sharps barrel, a shearing device is added, and the shearing device is used to cut or disassemble the sharps. The technical problem solved, the technical scheme adopted and the beneficial effects obtained correspond to each other and are clear.
