Description

Technical Field

[0001] The utility model relates to the technical field of straw labeling paper for IVF laboratories, in particular to a labeling paper instrument for IVF laboratories. Background Art

[0002] Embryo freezing is the only mature technology that can preserve fertility. It mainly involves vitrification of embryos obtained through in vitro fertilization. After being treated with a high concentration of cryoprotectant, the embryos are directly placed in liquid nitrogen to rapidly cool down, so that the cells are in a vitrified state between liquid and solid, and thus preserved for a long time. The medium that carries the embryos is frozen straws. In IVF laboratories, a large number of embryos are stored in cryopreservation tanks every day through labeled frozen straws.

[0003] Most of the label papers are rectangular in structure. After being pasted on the straw, different information can be displayed on different sides of the straw. For example, the label paper has the name, straw number, medical record number and freezing date, and the name and straw number are on the same line, and the next line is the medical record number and freezing date. When pasting the label paper to the straw, it is necessary to paste the label paper to the outer wall of the straw, and let the name and straw number be on one side wall of the straw, and the medical record number and freezing date be on the adjacent side wall. In this way, the name, straw number, medical record number and freezing date can be presented by rotating, which is convenient for subsequent use.

[0004] When sticking the label paper to the straw, it is often necessary to align and stick it manually, which is time-consuming and laborious. In addition, there is a possibility of misalignment and re-sticking. Utility Model Content

[0032] The technical solution of the utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, "multiple" means two or more, unless otherwise clearly and specifically defined. In addition, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0035] like Figure 1-6 As shown, Figure 4 The second motor is not shown. Figure 4 and Figure 5 Combined with understanding of this application, Figure 5 The middle arrow indicates the rotation direction of the second rotating shaft, the first slot section and the second slot section.

[0036] A labeling paper 8 instrument for IVF laboratory comprises a roller 1, a first push rod 2, a slot 3, a second push rod 4 and a pressure sensor 5.

[0037] Among them, the label paper 8 can be pasted on the roller 1 and can rotate circumferentially; specifically, the roller 1 is connected to the first rotating shaft 7 of the first motor 6, and the first motor 6 is used to drive the roller 1 to rotate circumferentially, so that the label paper 8 pasted on the roller 1 can move along the circumference of the roller 1.

[0038] The first push rod 2 is arranged below the roller 1 and on one side of the roller 1, so that after the roller 1 rotates to the right position, the first push rod 2 can push one end of the label paper 8 to move in the horizontal direction. Exemplarily, the first push rod 2 is an electric push rod. A top plate 16 is arranged at the telescopic end of the first push rod 2, so that when the first push rod 2 is extended, the top plate 16 presses the label paper 8 to move toward the opening of the slot 3.

[0039] The slot 3 is disposed below the drum 1, and an opening for pasting a label paper 8 on the straw 17 is disposed on the slot wall of the slot 3, so that the label paper 8 is pasted on the straw 17 inserted into the slot 3 through the opening. Specifically, the slot 3 is placed horizontally, and the insertion end of the slot 3 is arranged horizontally, that is, the straw 17 is inserted into the slot 3 in the horizontal direction, and at least a part of the straw 17 wall is exposed at the opening of the slot 3.

[0040] It should be noted that the slot 3 includes a first-section slot 9 and a second-section slot 10, the first-section slot 9 and the second-section slot 10 are arranged at intervals, and an opening is formed between the first-section slot 9 and the second-section slot 10; the inner circumferential cross-section of the first-section slot 9 is circular, the inner circumferential cross-section of the second-section slot 10 is square, and the inner circumferential circumference of the first-section slot 9 is smaller than the inner circumferential circumference of the second-section slot 10, so as to correspond to the change in the circumferential length of the wheat straw 17; the thinner end of the wheat straw 17 is inserted into the second-section slot 10, passes through the second-section slot 10, is inserted into the first-section slot 9, and is snapped onto the first-section slot 9.

[0041] The straw 17 is a conventional straw used in IVF laboratories, including a first section straw 11 and a second section straw 12. The first section straw 11 is thinner and square, with a transparent sheet for carrying embryos inside and a cylindrical straw cap 19 buckled outside. The second section straw 12 is thicker than the first section straw 11, and is a handheld end for sticking labels, and has a square circumferential cross section. The first section straw 11 is connected to the second section straw 12 to form the straw 17. The first section slot 9 and the second section slot 10 are coaxial. When the straw 17 is plugged into the slot 3, the first section of the straw 11 is first inserted into the second section of the slot 10. Next, the first section of the straw 11 passes through the second section of the slot 10 and is inserted into the first section of the slot 9. Moreover, since the inner circumferential cross-section of the first section of the slot 9 is smaller than the inner circumferential cross-section of the second section of the slot 10, the first section of the straw 11 can be limited so that the first section of the straw 11 is stuck in the first section of the slot 9. At this time, the second section of the straw 12 is partially located in the second section of the slot 10, thereby completing the plug-in fixation of the straw 17 and the slot 3.

[0042] It should also be noted that in order to achieve synchronous rotation of the slot 3, the walls of the first section slot 9 and the second section slot 10 are at least partially circular structures, so that the first section slot 9 and the second section slot 10 are respectively connected to the second rotating shaft 15 of the second motor 18, so that the second motor 18 drives the first section slot 9 and the second section slot 10 to rotate circumferentially, the second motor 18 is connected to the pressure sensor 5, and the second motor 18 starts to rotate in response to the pressure signal emitted by the pressure sensor 5, driving the first section slot 9 and the second section slot 10 to rotate.

[0043] Specifically, the circular parts of the first slot 9 and the second slot 10 have a gear tooth structure, and correspondingly, the second rotating shaft 15 of the second motor 18 also has a corresponding tooth structure. At this time, the tooth structure on the first slot 9 can be connected to the tooth structure on the transmission shaft by a transmission belt, and the connection structure between the second slot 10 and the second rotating shaft 15 is the same and will not be repeated. The first slot 9 is connected to the second rotating shaft 15 of the second motor 18 by a transmission belt, so that when the second motor 18 is working, it will drive the first slot 9 and the second slot 10 to rotate synchronously, and the opening between the first slot 9 and the second slot 10 is used for the pasting of the label paper 8.

[0044] The second push rod 4 is arranged below the first push rod 2 . The second push rod 4 is an electric push rod, and a pressure sensor 5 is provided on the top surface of the telescopic end of the second push rod 4 .

[0045] The pressure sensor 5 can sense the abutment of the end edge of the label paper 8 and form a pressure signal. That is, when the middle of the label paper 8 is pasted on the circumferential wall of the roller 1, the roller 1 rotates, driving one end of the label paper 8 to move toward the pressure sensor 5. When the label paper 8 abuts against the pressure sensor 5, the pressure sensor 5 forms a pressure signal and sends it to the first push rod 2. In response to the pressure signal, the first push rod 2 pushes the label paper 8 to move toward the opening of the slot 3 at its telescopic end, so that the label paper 8 is pasted on the side wall of the straw 17 inserted into the slot 3; the second push rod 4 retracts to make way for the slot 3, so that the slot 3 can rotate circumferentially and paste the label paper 8 on the wall of the straw 17.

[0046] It should be noted that the fixed ends of the first push rod 2 and the second push rod 4 are respectively fixed on the support seat 13 .

[0047] It should also be noted that after the pressure sensor 5 forms a pressure signal, the pressure signal is transmitted to the first motor 6 connected to the pressure sensor 5. The first motor 6 stops working in response to the pressure sensor 5 signal so that the roller 1 stops rotating. At this time, the roller 1 can rotate with the label paper 8.

[0048] In one embodiment, the axial length of the drum 1 is greater than the width of the label paper 8 , and an inwardly recessed axial groove (not shown in the figure) is provided on the outer wall of the drum 1 , and the distance between the groove walls is equal to the width of the label paper 8 .

[0049] In this way, when placing a label on the roller 1, the label can be conveniently and accurately placed in the groove.

[0050] In one embodiment, a plurality of protrusions (not shown in the figure) are arranged on the outer wall of the drum 1 so that the adhesive surface of the label paper 8 can be attached to the protrusions.

[0051] In this way, the contact area between the roller 1 and the adhesive surface of the label paper 8 is reduced, and the adhesive force formed by the bonding is also reduced, making it easier for the label paper 8 to be separated from the roller 1.

[0052] In one embodiment, the top surface of the pressure sensor 5 is located at 1 / 2 of the height of the slot 3, so that when the label paper 8 is pasted on the second section of the straw 12 of the straw 17, the label paper 8 is only pasted on 1 / 2 of the second section of the straw 12 of the straw 17. When the length of the label paper 8 is slightly larger than the outer wall of the straw 17, the two ends of the label paper 8 can at least partially overlap on the outer wall of the second section of the straw 12. To a certain extent, the problem of warping of the label paper 8 after being pasted on the straw 17 can be avoided.

[0053] In one embodiment, an instrument for labeling paper 8 used in an IVF laboratory also includes a limit plate 14, which is arc-shaped and is arranged on one side of the roller 1 to limit the moving direction of the label paper 8. The limit plate 14 is connected to the support seat 13 through a connecting rod so that the support seat 13 limits the limit plate 14.

[0054] In this way, the arc-shaped limiting plate 14 can limit the moving range of one end of the label paper 8 when the roller 1 rotates. That is to say, when the label paper 8 is pasted on the roller 1, one end of the label paper 8 is inserted between the roller 1 and the limiting plate 14, and the other end and the middle part of the label paper 8 are pasted on the roller 1. In this way, the end of the label paper 8 inserted between the roller 1 and the limiting plate 14 can move toward the pressure sensor 5 under the action of the limiting plate 14, so that when the label paper 8 rotates with the roller 1, the end of the label paper 8 can abut against the pressure sensor 5. In addition, the limiting plate 14 is connected to the support seat 13 by a connecting rod, which is convenient for fixing the position of the limiting plate 14. In addition, the position where the limiting plate 14 is connected to the connecting rod can be connected by a ball head, so that the inclination angle of the limiting plate 14 can be adjusted by using the structure of the ball head connection, and the ball head can be added as needed.

[0055] Example

[0056] 1. Insert the straw 17 into the slot 3 (after the straw 17 is inserted into the slot 3, a certain gap is left between the straw 17 and the slot 3 so that the outer wall of the straw 17 can be pulled out of the slot 3 after the label paper 8 is wrapped around it).

[0057] 2. Insert the end of the label paper 8 that is not pasted on the roller 1 between the roller 1 and the limiting plate 14. Next, paste the label paper 8 on the outer wall of the roller 1 with the protrusion. At this time, the second push rod 4 is in the expanded state so that the pressure sensor 5 is located at the lower part between the first push rod 2 and the slot 3.

[0058] 3. The first motor 6 drives the roller 1 to rotate slowly, and the label paper 8 moves toward the pressure sensor 5 under the limitation of the limiting plate 14 until it abuts against the pressure sensor 5 .

[0059] 4. The pressure sensor 5 senses the pressure, forms a pressure signal, and sends the pressure signal to the first motor 6 and the first push rod 2 respectively; the first motor 6 stops working in response to the pressure signal, and the drum 1 stops rotating; the first push rod 2 begins to unfold in response to the pressure signal, and pushes the top plate 16 at the telescopic end toward the slot 3. During the pushing process, the label paper 8 placed between the top plate 16 and the slot 3 is pushed toward the straw 17. Next, the top plate 16 sticks the label paper 8 on the straw 17, and continues to apply force so that the label paper 8 is firmly stuck to the wall of the straw 17.

[0060] 5. The first push rod 2 retracts, and the second push rod 4 retracts, respectively making way for the rotation of the slot 3.

[0061] 6. The pressure signal is also sent to the second motor 18. The second motor 18 starts to move after a preset delay (a conventional delay device, also called a timer, is provided on the second motor 18, and a delay time is pre-written in the delay device). The second rotating shaft 15 is used to drive the first slot 9 and the second slot 10 to rotate synchronously. During the slow rotation of the first slot 9 and the second slot 10, the label paper 8 will be pasted on the straw 17.

[0062] 7. The operation of the second motor 18 can be decomposed into four steps as needed. Each step rotates a certain number of times to rotate the first slot 9 and the second slot 10 by 90 degrees and stop rotating. At this time, an electrical signal will be sent to the first push rod 2. The first push rod 2 responds to the electrical signal and works once, that is, unfolds once, pushing the top plate 16 toward the straw 17. This action can press the label paper 8 and the straw 17 tightly, and then retracts; the second motor 18 then performs the next action according to the preset delay time, and similarly sends an electrical signal to the first push rod 2. The first push rod 2 responds to the electrical signal again, completes an unfolding action, and repeats the third and fourth steps. After four unfoldings, the first push rod 2 completes four squeezing of the label paper 8 and the straw 17, thereby fixing the label paper 8 on the straw 17.

[0063] 8. Take out the straw 17 and stick the straw 17 and the label paper 8 together.

[0064] It should be noted that in the above actions, the pressure signal flow and the electric signal flow involved can be set up with a control system as needed, and the pressure signal and electric signal flow can be completed by using the control system. Even if a control system is set up, the control system is a conventional control system and is only used for signal flow, and does not involve software. Even if software is involved, the software has not been improved. The control system is a conventional system.

[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
