Description

Technical Field

[0001] The present invention relates to the technical field of container separation operations, and specifically relates to a sharp instrument storage box with a sharp instrument separation function and its usage method. Background Art

[0002] A sharp instrument box can collect the needles of syringes, infusion sets, disposable items, medical small glass products, various blades, scalp needles, suture needles and other sharp instruments, and collect medical devices in contact with blood such as whole syringes and blood transfusion sets with blood.

[0003] The sharp instrument box is made of new polypropylene material, does not contain PVC, is convenient, safe, non-toxic, puncture-resistant, does not leak, is easy to incinerate at high temperature, and cannot be opened without damage after being closed.

[0004] However, the existing sharp instrument boxes have the following defects: When it is necessary to place the infusion tube and the needle of the syringe, usually medical staff need to manually cut the infusion tube or remove the syringe needle, and then place the needle in the sharp instrument box. During the operation, the needle is likely to pierce the hands of medical staff, endangering the personal safety of medical staff. At the same time, in order to prevent the glass items falling into the sharp instrument box from breaking and splashing, the input port of the sharp instrument box is usually set to be smaller. However, the smaller input port requires medical staff to accurately input when placing items, and the operation is relatively inconvenient. Summary of the Invention

[0052] The present invention will be described in detail below. The technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0053] The present invention provides an improved sharp instrument containing box with a sharp instrument separation function and its usage method here, mainly including two parts: a sharp instrument containing box with a sharp instrument separation function and a usage method of a sharp instrument containing box with a sharp instrument separation function. The technical solution of the present invention is as follows:

[0054] As Figures 1-5As shown in the figure, a sharp object containing box with a sharp object separation function includes: a housing 1. There are openings at the upper end and one side of the housing 1. A placement opening is provided on the front side of the housing 1. A sealing door 11 for closing the placement opening is hinged on the front side of the housing 1. A feeding hopper 2 communicating with the opening at the upper end of the housing 1 is fixed at the upper end of the housing 1. An anti-splash layer 21 is fixedly embedded in the inner wall of the feeding hopper 2. The anti-splash layer 21 is made by compounding an elastic fabric and a fluff fabric, has good deformation ability, and has a weak resilience. The anti-splash layer 21 effectively avoids the situation where the ampoule bottle breaks and splashes when the ampoule bottle is put in. The feeding hopper 2 expands the placement area, facilitating the staff to place sharp objects such as needles and glass utensils (such as ampoule bottles);

[0055] A separation component 3 is installed at the upper end of the housing 1. The separation component 3 includes a fixed clamping plate 31, a movable clamping plate 32 and a driving mechanism. The fixed clamping plate 31 is in an inverted L shape. The lower end of the vertical plate of the fixed clamping plate 31 is fixed to the upper surface of the housing 1. The movable clamping plate 32 is slidably connected to the vertical plate of the fixed clamping plate 31. The driving mechanism drives the movable clamping plate 32 to slide up and down along the vertical plate of the fixed clamping plate 31. Triangular clamping grooves 33 for clamping the head of the syringe barrel are provided on both the fixed clamping plate 31 and the movable clamping plate 32. The triangular clamping grooves 33 are located above the feeding hopper 2;

[0056] A cutting component 4 is installed inside the housing 1. The cutting component 4 includes a driving cylinder 41, a cutting knife 42 and a cutting plate group 43. The upper end of the driving cylinder 41 is fixed to the inner top wall of the housing 1. The piston rod of the driving cylinder 41 extends downward and is fixed to the upper end of the cutting knife 42. The cutting knife 42 is located above the cutting plate group 43. The cutting plate group 43 is located below the opening on one side of the housing 1. The cutting plate group 43 is fixedly installed on the inner side wall of the housing 1. A sliding mechanism is installed inside the housing 1. The housing 1 is slidably connected to a sharp object box 5 through the sliding mechanism. Both the feeding hopper 2 and the cutting plate group 43 are located above the opening of the sharp object box 5. The sharp object box 5 is adapted to the placement opening on the front side of the housing 1. The sharp object box 5 is used to contain sharp objects;

[0057] An inductor 8 is fixed to the inner top wall of the housing 1. The inductor 8 is located on the side of the cutting plate group 43 away from the side wall opening of the housing 1. The inductor 8 adopts a trigger sensor commonly used in the prior art and applicable to this embodiment. A pressure sensor (not shown in the figure) is fixedly embedded on the inner side wall of the triangular clamping groove 33 of the fixed clamping plate 31. The pressure sensor adopts a pressure sensor commonly used in the prior art and applicable to this embodiment. The specific model can be selected according to actual use requirements. An external controller (not shown in the figure) is installed outside the housing 1. The external controller is electrically connected to the inductor 8, the pressure sensor, the driving mechanism and the driving cylinder 41. The external controller adopts a programmable controller existing in the prior art. The external controller is used to receive the signals of the inductor 8 and the pressure sensor and control the opening and closing and lifting operations of the driving mechanism and the driving cylinder 41;

[0058] With the settings of the separation component 3, the cutting component 4, and the sensor 8, when it is necessary to separate the syringe needle, the medical staff only need to insert the front end of the syringe barrel with the needle into the triangular card slot 33 of the fixed clamping plate 31 and the movable clamping plate 32, so that the syringe needle is located at the lower end of the movable clamping plate 32. At this time, the pressure sensor receives the pressure and transmits the signal to the external controller. The external controller controls the driving mechanism to start. The driving mechanism drives the movable clamping plate 32 to descend, thereby removing the syringe needle and causing the syringe needle to fall into the material guiding hopper 2. The syringe needle finally falls into the sharp container 5 along the material guiding hopper 2, completing the separation operation of the syringe needle; when it is necessary to separate the infusion tube needle, the medical staff only need to insert one end of the infusion tube needle into the housing 1 through the side wall opening of the housing 1, so that the infusion tube and the needle are located between the cutting knife 42 and the cutting plate group 43. When one end of the infusion tube needle is located below the sensor 8, the sensor 8 is triggered. The sensor 8 sends a signal to the external controller. The external controller controls the driving cylinder 41 to start. The driving cylinder 41 drives the cutting knife 42 to descend and cooperate with the cutting plate group 43 to complete the cutting work of the infusion tube. The cut infusion tube needle falls into the sharp container 5, thereby completing the separation and collection operation of the infusion tube needle. The entire separation process avoids the contact between the medical staff's hands and the needle, thus preventing the situation where the needle pierces the medical staff's hands. At the same time, it is convenient for the medical staff to put items into the sharp container 5.

[0059] Furthermore, a sliding groove 311 and a mounting groove 312 are formed on the fixed clamping plate 31. The driving mechanism includes a screw rod 34 and a servo motor 35. The upper and lower ends of the screw rod 34 are respectively rotatably connected to the inner top wall and the inner bottom wall of the sliding groove 311. The servo motor 35 is fixedly installed in the mounting groove 312. The output shaft of the servo motor 35 penetrates the inner top wall of the mounting groove 312 and is fixed to the lower end of the screw rod 34. A slider 321 slidably connected to the sliding groove 311 is integrally formed on one side of the movable clamping plate 32. The screw rod 34 threadedly penetrates the middle of the slider 321. The servo motor 35 is electrically connected to the external controller. When the front end of the syringe barrel with the needle is inserted into the triangular card slot 33 of the fixed clamping plate 31 and the movable clamping plate 32, the pressure sensor receives the pressure and transmits the signal to the external controller. The external controller controls the servo motor 35 to start and drives the screw rod 34 to rotate. When the screw rod 34 rotates, it drives the movable clamping plate 32 to descend, thereby completing the separation and removal operation of the syringe needle.

[0060] Further, the cutting plate group 43 includes a fixed block 431, a reset elastic member, and a movable cutting plate 433. One side of the fixed block 431 is fixed to the inner side wall of the housing 1. The fixed block 431 is located below the opening of the side wall of the housing 1. The movable cutting plate 433 is hinged to the fixed block 431 through the reset elastic member. The movable cutting plate 433 rotates downward. When the cutting knife 42 descends under the drive of the drive cylinder 41, the cutting knife 42 presses the infusion tube tightly and presses down the movable cutting plate 433, making the movable cutting plate 433 form an inclined surface. When pressed down to a certain position, the movable cutting plate 433 abuts against the fixed block 431. At this time, the cutting knife 42 cuts off the infusion tube, and the infusion tube needle slides down along the movable cutting plate 433 into the sharp container 5, preventing the infusion tube needle from staying on the movable cutting plate 433.

[0061] Further, the reset elastic member includes a spring piece 432. The cross-section of the spring piece 432 is in the shape of Ω. An arc-shaped hole is formed in the fixed block 431. One end of the spring piece 432 passes through the arc-shaped hole in the fixed block 431 and is fixed to the bottom surface of the fixed block 431. The other end of the spring piece 432 is fixed to the bottom surface of the movable cutting plate 433. The spring piece 432 drives the movable cutting plate 433 to reset after cutting off the infusion tube, so as to facilitate the next cutting operation.

[0062] Further, a guide plate 13 is fixed to the inner side wall of the housing 1. The guide plate 13 is located below the cutting plate group 43. The guide plate 13 is inclined. A blocking plate 14 is installed above the guide plate 13. The blocking plate 14 is fixed to the inner wall of the housing 1 through a connecting column. The blocking plate 14 is located above the cutting plate group 43 and on the side of the sensor 8 away from the opening of the side wall of the housing 1. The guide plate 13 can further guide the cut infusion tube needle. When the infusion tube needle has not left the movable cutting plate 433, when the movable cutting plate 433 bounces up, the infusion tube needle is thrown out. At this time, the blocking plate 14 intercepts the thrown infusion tube needle, making the infusion tube needle fall downward into the sharp container 5. The blocking plate 14 and the guide plate 13 cooperate to play a good guiding role for the infusion tube needle, preventing the infusion tube needle from failing to fall or falling out of the collection range of the sharp container 5.

[0063] Further, an auxiliary clamp 36 is rotatably connected to the upper surface of the fixed clamping plate 31. The auxiliary clamp 36 is used to clamp the syringe barrel. Through the arrangement of the auxiliary clamp 36, after the medical staff places the syringe with a needle, the syringe barrel is clamped by the auxiliary clamp 36, thus liberating the hands of the medical staff and achieving the purpose of automatically separating and removing the syringe needle, making the removal of the syringe needle more convenient.

[0064] Further, the sliding mechanism includes a slide rail 12 and a slide bar 51. There are two slide rails 12, which are symmetrically fixed on the inner walls of both sides of the housing 1. There are two slide bars 51, which are respectively slidably connected to the two slide rails 12. The ends of the two slide bars 51 far from the slide rails 12 are both fixed to the side wall of the sharp container 5. Support handles 52 are fixed on the front and rear sides of the sharp container 5. The two support handles 52 are respectively in contact with the inner wall of the sealing door 11 and the inner side wall of the housing 1. Medical staff can drive the sharp container 5 to slide along the slide rail 12 by simply pushing or pulling the support handle 52, so as to take out or install the sharp container 5 in the housing 1, thus completing the installation or removal operation of the sharp container 5. The installed sharp container 5 is jointly supported and positioned by the two slide bars 51 and the two support handles 52, avoiding displacement of the sharp container 5 in the housing 1.

[0065] Further, a sharp container with a sharp separation function further includes a distance measuring sensor 9 and an alarm. The distance measuring sensor 9 is fixed to the inner top wall of the housing 1. The distance measuring sensor 9 is located above the sharp container 5. The alarm is installed outside the housing 1. Both the distance measuring sensor 9 and the alarm are electrically connected to an external controller. The distance between the items in the sharp container 5 and the inner top wall of the housing 1 is measured by the distance measuring sensor 9, and an alarm is issued by the alarm when a predetermined distance is reached (the height of the items in the sharp container 5 reaches three-quarters of the position of the sharp container 5), so as to prompt medical staff to replace the sharp container 5 in time.

[0066] Further, a hole cover 6 is fixed at the opening of the side wall of the housing 1. The hole cover 6 uses a rubber hole cover commonly used in the prior art and suitable for this embodiment. A rubber soft curtain is provided in the middle thereof, which can block and seal the opening of the side wall of the housing 1, separating the inside of the housing 1 from the external environment.

[0067] Further, balls 7 are rollingly embedded in the inner bottom wall of the housing 1. The balls 7 are in rolling contact with the bottom surface of the sharp container 5. The arrangement of the balls 7 reduces the friction between the sharp container 5 and the housing 1, making it more convenient and labor-saving for medical staff to push and pull the sharp container 5.

[0068] As Figures 1-6 shown, a method for using a sharp container with a sharp separation function is applicable to the above-mentioned sharp container with a sharp separation function. The specific steps are as follows:

[0069] S1. Put an empty sharp container 5, open the sealing door 11, and push the support handle 52 to drive the sharp container 5 to slide along the slide rail 12, and put the sharp container 5 into the housing 1, thus completing the installation operation of the empty sharp container 5;

[0070] S2. Separate the syringe needle, infusion tube needle or put in an ampoule bottle, specifically including:

[0071] S21. Separate the syringe needle. The medical staff inserts the front end of the syringe barrel with the needle into the triangular card slot 33 of the fixed card board 31 and the movable card board 32, so that the syringe needle is located at the lower end of the movable card board 32. At this time, the pressure sensor receives the pressure and transmits the signal to the external controller. The external controller controls the servo motor 35 to start and drives the screw rod 34 to rotate. When the screw rod 34 rotates, it drives the movable card board 32 to descend, thereby removing the syringe needle and making the syringe needle fall into the feeding hopper 2. Finally, the syringe needle falls into the sharps container 5 along the feeding hopper 2;

[0072] S22. Separate the infusion tube needle. Insert one end of the infusion tube needle into the housing 1 through the opening on the side wall of the housing 1, so that the infusion tube and the needle are located between the cutting knife 42 and the cutting plate group 43. When one end of the infusion tube needle is below the sensor 8, the sensor 8 is triggered. The sensor 8 sends a signal to the external controller. The external controller controls the driving cylinder 41 to start. The driving cylinder 41 drives the cutting knife 42 to descend and cooperate with the cutting plate group 43 to complete the cutting work of the infusion tube. The cut infusion tube needle falls into the sharps container 5;

[0073] S23. Insert the ampoule bottle. Insert the ampoule bottle into the feeding hopper 2. The ampoule bottle first contacts the splash-proof layer 21 and slides down along the feeding hopper 2 into the sharps container 5 to complete the insertion work of the ampoule bottle;

[0074] S3. Take out the nearly full sharps container 5. When the distance measuring sensor 9 detects that the sharps loaded in the sharps container 5 reach a certain height, the distance measuring sensor 9 transmits the signal to the external controller. The external controller controls the alarm to sound. The medical staff opens the sealed door 11 and pulls the support handle 52 to drive the sharps container 5 to slide along the slide rail 12 and take out the sharps container 5 from the housing 1, thereby completing the removal operation of the sharps container 5;

[0075] S4. Repeat the operation of S1 to complete the replacement operation of the sharps container 5.

[0076] Working principle: During daily use, medical staff first need to open the sealed door 11. By pushing the support handle 52, the sharp container 5 can be driven to slide along the slide rail 12, and the sharp container 5 is placed into the outer shell 1 to complete the installation operation of the empty sharp container 5. When separating the syringe needle, medical staff only need to insert the front end of the syringe barrel with the needle into the triangular card slot 33 of the fixed card plate 31 and the movable card plate 32, so that the syringe needle is located at the lower end of the movable card plate 32. At this time, the pressure sensor receives the pressure and transmits the signal to the external controller. The external controller controls the servo motor 35 to start and drives the screw 34 to rotate. When the screw 34 rotates, it drives the movable card plate 32 to descend, thereby removing the syringe needle and causing the syringe needle to fall into the material guiding hopper 2. The syringe needle finally falls into the sharp container 5 along the material guiding hopper 2 to complete the separation operation of the syringe needle; when separating the infusion tube needle, medical staff only need to insert one end of the infusion tube needle into the outer shell 1 through the opening on the side wall of the outer shell 1, so that the infusion tube and the needle are located between the cutting knife 42 and the cutting plate group 43. When one end of the infusion tube needle is below the sensor 8, the sensor 8 is triggered. The sensor 8 sends a signal to the external controller, and the external controller controls the driving cylinder 41 to start. The driving cylinder 41 drives the cutting knife 42 to descend and cooperate with the cutting plate group 43 to complete the cutting work of the infusion tube. The cut infusion tube needle falls into the sharp container 5, thereby completing the separation and collection operation of the infusion tube needle. The entire separation process avoids the contact between the hands of medical staff and the needle, thus preventing the situation where the needle pierces the hands of medical staff. At the same time, it is convenient for medical staff to put items into the sharp container 5.

Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to these embodiments shown herein, but will be accorded the widest scope consistent with the principles and novel features disclosed herein.
