DETAILED DESCRIPTION

[0035] The following will be described clearly and completely in conjunction with the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Embodiment, this embodiment provides a medical sterile article time management label printer, such as Figure 1 , Figure 2 as well as Figure 3As shown, the machine body 1 includes a PLC 5 and a thermal printer 8 built in the machine body 1. The machine body 1 is also provided with a power module 10, which is a lithium battery. The terminal of the lithium battery is connected to the terminal of the PLC 5, and the lithium battery supplies power to the PLC 5. A plurality of buttons 11 are also installed on the upper end surface of the machine body 1. The buttons 11 include a power button and a time operation button for controlling the power module 10. The time operation button includes 2h, 4h, 8h, 24h, 48h, 30d and 60d operation buttons, which are responsible for the time operation and control of the entire printer. The PLC 5 is also connected to a display screen 12 embedded in the surface wall of the machine body 1 to display power and instructions. As the core control center of the printer, the PLC 5 is responsible for receiving external instructions (such as printing tasks from computers or smart devices) and decoding and processing these instructions. Including receiving signals, processing data, and controlling the heating of the thermal printer 8.

[0037] like Figure 3 As shown, the thermal printer 8 has a thermal print head, which is used to contact the label paper for printing. The signal input port of the PLC 5 is connected to a temperature sensor 6 and a position sensor 7. The temperature sensor 6 is used to detect the heating temperature of the thermal print head, and the position sensor 7 is used to detect the conveying position of the label paper. Notches are provided on the opposite side walls of the paper slot 15, and a paper shaft 4 for sleeves of the label paper is provided between the two notches. A stepper motor 9 for providing power to the paper shaft 4 is embedded in the inner wall of the paper slot 15, and the wiring terminal of the stepper motor 9 is connected to the signal output terminal of the PLC 5. Specifically, a transmission sleeve can be provided in one of the notches, one end of the transmission sleeve is tightly plugged with the output end of the stepper motor 9, and the other end of the transmission sleeve is tightly plugged with one end of the paper shaft 4. Since the label paper sleeved on the paper shaft 4 is light in weight, there will be no slipping phenomenon.

[0038] The machine body 1 is also provided with a paper slot 15 for storing label paper and a paper slot cover 2 that can cover the upper opening of the paper slot 15. A paper outlet 21 is left between the side wall of the end of the paper slot cover 2 and the side wall of the upper opening of the paper slot 15. Specifically, a connecting block 14 is fixed to one side wall of the paper slot 15 away from the paper outlet 21. Both sides of the connecting block 14 are rotatably provided with connecting rods 23. A docking seat 22 is fixed to the inner side wall of the paper slot cover 2. The ends of the two connecting rods 23 are respectively fixedly connected to the side walls of the docking seat 22. The paper slot cover 2 is turned around the side wall of the connecting block 14 by connecting the connecting rods 23 with the docking seat 22, so that it can be opened and covered with the opening of the paper slot 15. Before printing, open the paper slot cover 2, prepare the label paper and put it on the paper shaft 4, and then put it into the paper slot 15. One end of the paper shaft 4 is tightly sleeved with the transmission sleeve, and the other end is rotated and placed in another notch, and the paper slot cover 2 is covered.

[0039] After the label paper is installed, the thermal print head starts to energize and heat up according to the printing instruction, and the stepper motor 9 provides power to drive the paper shaft 4 to rotate, so that the label paper is stably and evenly moved to the heated thermal print head, and the label paper (using thermal paper) moves, and the heating element contacts the label paper. At this time, the special chemical substances on the label paper begin to react chemically and develop color (chemical reaction color development: under the high temperature of the heating element, the coating on the thermal paper reacts chemically, and the color changes, usually from colorless to black or dark, thereby forming the desired image or text), and the printed label paper is sent out from the paper outlet 21 to complete a single print.

[0040] The label paper shows the input initial information, start date and end date. At the same time, the input initial information, start date and end date will be recorded in the storage module connected to PLC 5. These labels are used to record the opening time and expiration date of medical sterile items. Through the information on the label paper, medical staff can easily track the use of sterile items to avoid the continued use of sterile items after the expiration date, thereby reducing the risk of nosocomial infection.

[0041] At the same time, PLC 5 has a receiving module, an identification module, a storage module and a time management module. The signal output port of PLC 5 is connected to a buzzer 13. The receiving module receives the printing request of the user terminal, obtains the identity information and pre-printed files of the user terminal, and identifies the identity information of the access printer through the identification module, compares it with the identity information of the pre-printed files in the storage module, matches the corresponding pre-printed files, and prints the pre-printed files; wherein the identification module also includes a marking unit, which marks the pre-printed files with the identity information and time information of the user terminal as tags, and stores them in the storage module; the storage module also includes a file self-cleaning unit for file management, and the file self-cleaning unit receives the time threshold information of the time management module to perform regular cleaning of the pre-printed files. PLC 5 sets the alarm threshold of the buzzer 13, that is, the sterile items trigger the alarm at a certain time point before the expiration date (such as one week or one month in advance). PLC 5 will monitor the current date in real time and compare it with the expiration date of the sterile items and the set alarm threshold. When the current date reaches or exceeds the alarm threshold, PLC 5 will trigger the buzzer 13 to alarm, thereby prompting medical staff to deal with it in time.

[0042] In summary, the above structure is applied to the management of the opening and stopping validity period of medical sterile items such as medical cotton swabs, medical alcohol, quick hand disinfection, sterile towels, sterile gauze, and sterile medicines. It can also be used for the management of the validity period of some medical devices (including but not limited to sterile surgical instruments, sterile catheters and drainage tubes, sterile syringes and needles).

[0043] After printing, the label paper needs to be torn off at the paper outlet 21 and then pasted on a more conspicuous position of the sterile article. Although the labels printed by the existing printer can be torn off with the help of the sawtooth bar, it is necessary to hold the machine body 1 with one hand and pull the label paper against the sawtooth bar with the other hand to tear it off. Generally, the tear marks are not flush. If too much force is used, unused labels may be pulled out, causing waste.

[0044] In order to solve the above problems, Figure 1 and Figure 2 As shown, it also includes multiple blades 3 for cutting labels, and the paper slot 15 is located at the side of the paper outlet 21 and has a built-in transmission cavity. Multiple T-shaped sliders 31 are slidably inserted in the transmission cavity. The ends of the T-shaped sliders 31 slide out of the transmission cavity and are fixedly connected to the backs of the blades 3; Figure 4 As shown, in this embodiment, two blades 3 are preferably provided, and a gap is provided between the two blades 3, and two T-shaped sliders 31 are also provided, and are fixedly connected to the backs of the two blades 3 respectively; Figure 5 , Figure 6 as well as Figure 7 As shown, a push hole 37 is opened at one end of the T-shaped slider 31 located in the transmission cavity, and a side wall of the push hole 37 close to the blade 3 is inclined toward a side away from the transmission seat 32 to form an inclined side wall.

[0045] The transmission component also includes a transmission seat 32 fixed in the transmission cavity and located between two T-shaped sliders 31, a push rod 34 is slidably inserted in the transmission seat 32, and one end of the two push rods 34 located in the transmission seat 32 is connected to an L-shaped extension block 310, the ends of the two extension blocks 310 are parallelly distributed and are both made of iron structure, an electromagnet 39 located between the ends of the two extension blocks 310 is fixed at the center position of the transmission seat 32, and the terminal of the electromagnet 39 is connected to the terminal of the PLC 5; the ends of the two push rods 34 that are away from each other slide out of the transmission seat 32 and are directly distributed with the push hole 37, such as Figure 8 As shown, PLC 5 is connected to the circuit of electromagnet 39. Electromagnet 39 generates adsorption force when energized, which can adsorb the two extension blocks 310 and slide toward the side close to electromagnet 39, and the ends of the two push rods 34 that are away from each other can extend toward the side away from each other, thereby driving the ends of the push rods 34 to extend into the push hole 37 and slide along the inclined side wall in the push hole 37, thereby providing lateral thrust for the T-shaped slider 31, and then driving the blade 3 to move forward to contact the label paper for cutting operation.

[0046] However, the special design of the blade 3 is that it is not a simple contact with the label paper and a hard full cutting operation, but a plurality of spike ends are provided on the blade 3, and there is a gap between two adjacent spike ends, such as Figure 4As shown, when the blade 3 moves forward to contact the label paper, the sharp end can penetrate the label paper, forming multiple evenly distributed cutting holes on the label paper, and the multiple cutting holes are on the same horizontal line, which is equivalent to leaving a row of porous tear marks on the label paper. You only need to pinch the corner of the label paper with one hand and tear it slightly horizontally, and you can easily tear off the label paper along the row of porous tear marks. The tear marks are neat, and the unprinted label paper will not be pulled out of the paper outlet 21 due to excessive force. Compared with the method of pure manual tearing or cutting with the aid of a sawtooth bar in the prior art, it can ensure neat tear marks and is easier to tear.

[0047] At the same time, if Figure 6 As shown, the side walls of both sides of the T-shaped slider 31 are rotatably embedded with multiple sliding rollers 36. The sliding resistance between the T-shaped slider 31 and the inner wall of the transmission cavity is reduced. At the same time, an I-shaped wheel 38 that can roll against the inclined side wall in the push hole 37 is rotatably provided at the end of the push rod 34. The I-shaped wheel 38 rolls along the inclined side wall, which can reduce the pushing resistance when the push rod 34 is extended.

[0048] In this embodiment, further, Fig. 9 As shown, a mounting groove is provided on the side wall of the docking seat 22 facing the blade 3, and matching blocks 24 are fixed on the upper and lower side walls of the mounting groove. A gap is left between the two matching blocks 24, and the gap is horizontally opposite to the blade of the blade 3. In addition, a circular arc slope is provided on the side wall of the adjustment block facing the blade 3, and a hollow structure 25 is provided on the adjustment block near the circular arc slope. After the blade 3 moves forward to contact the label paper, it continues to move forward, and the label paper can be pressed against the side walls of the two matching blocks 24. At the same time, the spike end of the blade 3 can pierce the label paper and enter the gap between the two matching blocks 24. In addition, the adjustment block is provided with a hollow structure 25 at the circular arc slope position. When the spike end of the blade 3 enters the gap, the circular arc slope can be pressurized to produce bending deformation, and fit on the surface wall of the spike end, so as to avoid the label paper being brought into the gap by the spike end due to the gap being too large, which affects the spike end piercing the label paper to form a porous cutting hole.

[0049] After tearing off the label paper, the blade 3 needs to be reset. In this case, an extension plate 33 is fixed to the outer wall of the transmission seat 32. Both sides of the end of the extension plate 33 are fixed with arc-shaped spring pieces 35. The arc-shaped spring piece 35 is fixedly connected to one end of the T-shaped slider 31 located in the transmission cavity. Figure 4 As shown, when the blade 3 moves forward for cutting, the arc-shaped spring piece 35 is stretched and deformed. After cutting, the circuit of the electromagnet 39 is disconnected, and the two extension blocks 310 lose their adsorption force. Then the arc-shaped spring piece 35 is reset, and can pull the T-shaped slider 31 and the blade 3 to slide in the opposite direction, thereby resetting the blade 3 so that the subsequent label paper can be output from the paper outlet 21 after printing.

[0050] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
