Description
Technical Field
[0001] This utility model relates to the field of medical device technology, specifically to a sharps container box. Background Technology
[0002] Sharps containers are essential for hospitals when disposing of medical waste. Most existing sharps containers are round or square plastic boxes, mainly used to collect syringes, infusion sets, and needles from disposable items. For example, intravenous needles are used clinically, but they are always connected to infusion tubing when being retrieved. If the infusion tubing and needle are thrown directly into the container, it will take up a lot of space. Therefore, sharps containers separate the infusion tubing and needle.
[0003] When separating the needle from the IV tubing, medical staff usually use scissors to cut the connection between the needle and the tubing, and then put the needle into the sharps container through the collection port at the top of the sharps container. This not only requires scissors, which is inconvenient, but also takes time and effort and can contaminate the scissors.
[0004] To address the above problems, this utility model provides a sharps box that facilitates the separation of infusion tubing and needles. Utility Model Content
[0005] The technical problem to be solved by this utility model is to provide a sharps box that facilitates the separation of infusion tubes and needles, thereby reducing the workload of medical staff.
[0006] To solve the above problems, the present invention adopts the following technical solution:
[0007] A sharps container storage box includes a box body, a sharps box, and scissors; its distinguishing feature is that the sharps box storage box also includes electric push rods, an infrared sensing module, a microcontroller module, and a power supply module; the sharps box is disposed inside the box body, the upper end of the box body is provided with a box lid, the box lid has an opening corresponding to the collection port of the sharps box, and a side opening is provided on the upper part of one of the side walls of the box body; the blade of the scissors extends into the box body from the side opening and is located in the middle of the opening of the box lid, the hinge shaft of the scissors is connected to the lower surface of the box lid, and the two handles of the scissors are located outside the box body; two electric push rods are provided, one each located at the side opening. On both sides, an electric actuator is connected to the handle of a pair of scissors, with one end of the actuator hinged to the handle and the other end hinged to the side wall of the housing. The infrared sensing module includes an infrared transmitter and an infrared receiver mounted on the surface of the housing, with the infrared receiver positioned next to the infrared transmitter to receive infrared light reflected from the hand and generate a feedback signal. A microcontroller module is mounted on the side wall of the housing and is electrically connected to the infrared receiver and the two electric actuators, respectively, to control the electric actuators after receiving the feedback signal from the infrared receiver. The power supply module provides the operating voltage.
[0008] The beneficial effects of this utility model are:
[0009] This utility model provides a sharps container. When it is necessary to separate an IV tube and needle, the connection between the IV tube and needle is placed between the two blades of scissors through the opening of the container lid. Then, the medical staff places their other hand above the infrared sensing module. The infrared rays emitted by the infrared emitter are reflected by the hand and received by the infrared receiver. The infrared receiver sends the received infrared feedback signal to the microcontroller module. After processing the feedback signal, the microcontroller module controls two electric push rods to work. The telescopic rods of the two electric push rods extend, thereby pushing the two handles of the scissors to move towards each other, so that the two blades of the scissors come together and cut the connection between the IV tube and the needle. Afterward, the needle falls into the sharps container, thus achieving the purpose of replacing manual separation of needles and IV tubes, providing convenience for medical staff and reducing their workload.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0021] like Figures 1 to 9 As shown, the sharps box storage box in this embodiment includes a box body 1, a sharps box 2, scissors 3, an electric push rod 4, an infrared sensing module 5, a microcontroller module 6, and a power supply module 7.
[0022] The sharps container 2 is a square box with its collection opening located in the center of its upper surface. The sharps container 2 is housed inside the box body 1. The box body 1 has a lid 11 at its upper end, with an opening 111 corresponding to the collection opening of the sharps container 2. A side opening 12 is located on the upper part of one side wall of the box body 1. Another side wall of the box body 1 has an inlet 13 for inserting the sharps container 2, facilitating replacement. The inlet 13 is fitted with a side cover 20, which can be rotated open and has a handle on its surface.
[0023] The scissors 3 in this embodiment are common household scissors, mainly consisting of two rods connected by a hinge shaft 32. The front ends of the two rods are equipped with sharp blades 31, and the rear ends are equipped with handles 33. The scissors 3 in this embodiment may be larger than ordinary household scissors. The blades 31 of the scissors 3 extend into the box body 1 from the side opening 12 and are located in the middle of the opening 111 of the box cover 11. The hinge shaft 32 of the scissors 3 is connected to the lower surface of the box cover 11, and the two handles 33 of the scissors 3 are located outside the box body 1.
[0024] Two electric actuators 4 are provided, one on each side of the side opening 12. Each electric actuator 4 is connected to a handle 33 of a pair of scissors 3, with one end of the actuator 4 hinged to the handle 33 and the other end hinged to the side wall of the housing 1. When the two electric actuators 4 extend, the two handles 33 of the scissors 3 move towards each other, causing the two blades 31 of the scissors 3 to come closer together; when the two electric actuators 4 shorten, the two handles 33 of the scissors 3 move towards the electric actuator 4 connected to them, causing the two blades 31 of the scissors 3 to separate.
[0025] The infrared sensing module 5 includes an infrared transmitter 51 and an infrared receiver 52 mounted on the surface of the cover 11. The infrared receiver 52 is positioned beside the infrared transmitter 51 to receive infrared light reflected from the hand and generate a feedback signal. The microcontroller module 6 is mounted on the side wall of the housing 1 and is electrically connected to the infrared receiver 52 and two electric actuators 4. It controls the electric actuators 4 to operate after receiving the feedback signal from the infrared receiver 52. The power supply module 7 provides the operating voltage.
[0026] In this embodiment, the infrared transmitter 51 is an infrared emitting tube, specifically the IR333_H0 infrared emitting tube. The infrared receiver 52 uses an HS0038B chip. In the circuit, the signal output terminal (DATE pin) of the infrared receiver 52 is electrically connected to the input terminal (I / O pin) of the microcontroller module 6, used to input feedback signals to the microcontroller module 6. When the infrared receiver 52 receives infrared light, its signal output terminal outputs a high-level signal; when the infrared receiver 52 cannot receive infrared light, its signal output terminal outputs a low-level signal.
[0027] Each of the two electric actuators 4 has a drive module connected to the output of the microcontroller module 6. The two drive modules have identical circuit diagrams and operate on the same principle. Specifically, the drive module includes a first drive circuit and a second drive circuit. The first drive circuit includes a first relay and a first transistor. The base of the first transistor is electrically connected to the output of the microcontroller module 6, the collector is electrically connected to the negative terminal of the first relay coil, and the emitter is electrically connected to the GND terminal. The positive terminal of the first relay coil is electrically connected to the positive terminal of the power supply module 7. The normally open terminal of the first relay is electrically connected to the positive terminal of the power supply module 7, the normally closed terminal is electrically connected to the negative terminal of the power supply module 7, and the common terminal is electrically connected to the positive terminal of the power supply for the first electric actuator 4. The second drive circuit includes a second relay and a second transistor. In this circuit, the base of the second transistor is electrically connected to the output terminal of the microcontroller module 6, the collector is electrically connected to the negative terminal of the coil of the second relay, and the emitter is electrically connected to the GND terminal; the positive terminal of the coil of the second relay is electrically connected to the positive terminal of the power supply module 7; the normally open terminal of the second relay is electrically connected to the negative terminal of the power supply module 7, the normally closed terminal is electrically connected to the positive terminal of the power supply module 7, and the common terminal is electrically connected to the negative terminal of the power supply of the electric actuator 4. Typically, the electric actuator is driven by a motor; therefore, in the circuit, an uppercase "M" represents the electric actuator.
[0028] The working principle is as follows: When the first transistor is turned on, the coil of the first relay is energized, and the normally open terminal of the first relay is conducting. The second transistor is not turned on, so the coil of the second relay is not energized, and the normally closed terminal of the second relay is conducting. Current flows through the positive terminal of the power module 7, the normally open terminal of the first relay, to the positive terminal of the motor, then from the negative terminal of the motor to the normally closed terminal of the second relay, and finally back to the negative terminal of the power module 7, thus making the motor conduct electricity in the forward direction. At this time, the electric push rod 4 is defined as extending. Conversely, when the second transistor is turned on, the coil of the second relay is energized, and the normally open terminal of the second relay is conducting. The first transistor is not turned on, so the coil of the first relay is not energized, and the normally closed terminal of the first relay is conducting. Current flows through the positive terminal of the power module 7, the normally open terminal of the second relay, to the negative terminal of the motor, then from the positive terminal of the motor to the normally closed terminal of the first relay, and finally back to the positive terminal of the power module 7, thus making the motor conduct electricity in the reverse direction. At this time, the electric push rod 4 is defined as shortening.
[0029] It should be noted that in the circuit diagram, the two electric actuators 4 are represented by M1 and M2, respectively. The first transistor and the second transistor corresponding to the electric actuator M1 are represented by Q1 and Q2, respectively, and the first relay and the second relay are represented by KA1 and KA2, respectively. The first transistor and the second transistor corresponding to the electric actuator M2 are represented by Q3 and Q4, respectively, and the first relay and the second relay are represented by KA3 and KA4, respectively.
[0030] When it is necessary to separate the infusion tubing and needle, place the connection between the tubing and needle through the opening 111 of the cover 11 between the two blades 31 of the scissors 3. Then, the medical staff places their other hand above the infrared sensing module 5. The infrared rays emitted by the infrared emitter 51 are reflected from the hand to the infrared receiver 52. The infrared receiver 52 sends the received infrared feedback signal (high-level signal) to the microcontroller module 6. After receiving the feedback signal, the microcontroller module 6, according to its built-in computer program, sends signals to the drive modules connected to the two electric push rods 4 respectively. A high-level input to the base of a transistor turns on the two first transistors (Q1 and Q3), while the two second transistors (Q2 and Q4) turn off. This causes the two electric actuators 4 to extend, moving the two handles 33 of the scissors 3 towards each other. This causes the two blades 31 of the scissors 3 to come together and cut the connection between the IV tubing and the needle. The needle then falls into the sharps container 2, thus achieving the purpose of replacing manual separation of the needle and IV tubing, providing convenience for medical staff and reducing their workload. At this time, the microcontroller module 6 starts timing (generally, a microcontroller has a timing / counting function). After the timing time is up, the microcontroller module 6 inputs a high level to the base of the two second transistors, causing the two second transistors (i.e., transistors Q2 and Q4) to conduct. At this time, the two first transistors (i.e., transistors Q1 and Q3) do not conduct, thereby causing the two electric actuators 4 to shorten. This causes the two handles 33 of the scissors 3 to move towards the electric actuators 4 connected to them, causing the two blades 31 of the scissors 3 to separate and finally return to the initial position. If the hand is still placed above the infrared sensing module 5, the microcontroller module 6 continues to control the two electric actuators 4 to extend; if the hand is removed from the infrared sensing module 5, it remains in the initial position.
[0031] In summary, after the hand is removed from the infrared sensing module 5, the infrared receiver 52 can no longer receive infrared light, and the microcontroller module 6 will control the two electric push rods 4 to return to their initial positions according to its built-in program; after the hand is placed on the infrared sensing module 5 again, the microcontroller module 6 will control the two electric push rods 4 to extend.
[0032] In addition, the opening 111 on the box cover 11 in this embodiment is circular, and a screw cap 8 is provided on the opening 111 of the box cover 11. The screw cap 8 is positioned above the opening 111 and is used to block the opening 111. Before the screw cap 8 is opened, the blade 31 of the scissors 3 cannot be exposed, thus improving the safety of use. A stepper motor 9 is located below the lid 11 and opposite the scissors 3. The shaft of the stepper motor 9 extends out of the lid 11 and is connected to the screw cap 8. A motor control button 10 is located above the lid 11. Both the motor control button 10 and the stepper motor 9 are electrically connected to the microcontroller module 6. The stepper motor 9 is used to drive the screw cap 8 to rotate. In this embodiment, a ULN2803 driver chip is provided between the stepper motor 9 and the microcontroller module 6 to drive the stepper motor 9 to rotate. In the circuit, the stepper motor 9 is represented by M3, and the motor control button 10 is represented by buttons K2 and K3. When button K2 is pressed, the microcontroller module 6 controls the stepper motor 9 to rotate 180° according to its built-in program, so that the screw cap 8 rotates 180° and exposes the opening 111 of the lid 11. When button K3 is pressed, the microcontroller module 6 controls the stepper motor 9 to rotate 180° again, so that the screw cap 8 rotates 180° and blocks the opening 111 of the lid 11 again.
[0033] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
