Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a heating device for a Pasteur pipette. Background Art

[0002] Pasteur pipettes are commonly used medical consumables in the embryo laboratory of the reproductive center. They are used for the transfer of eggs, cleavage-stage embryos, morulae, and blastocysts (cell volumes increase in sequence). Since the size of embryos at different stages is different, laboratory personnel are required to burn Pasteur pipettes with different inner diameters. The specific operation process is as follows:

[0003] First, place the Pasteur pipette on the outer flame of an alcohol lamp (temperature is generally 665℃) and bake until it melts, then quickly leave the flame and stretch it with both hands, and control the stretching length. The longer the stretching length, the thinner the inner diameter. Conversely, the shorter the stretching length, the thicker the inner diameter.

[0004] Then, the stretched Pasteur straw is cut with a grinding wheel, and the cut end is slightly scalded with the inner flame of an alcohol lamp (the temperature is generally 520° C.) until it is smooth, thus completing the production of the Pasteur straw with a predetermined inner diameter.

[0005] However, the applicant found that in the above process, since an alcohol lamp is required, there are at least the following problems:

[0006] 1. The open flame of the alcohol lamp and the lighter used for ignition are not conducive to the fire safety of the embryo laboratory;

[0007] 2. The alcohol lamp uses 95% pure industrial alcohol, which is highly volatile and affects the air quality of the embryo laboratory;

[0008] 3. Alcohol lamps produce toxic and harmful substances, which affect the air quality of the embryo laboratory and the health of the staff;

The additional management of the storage of industrial alcohol with a purity of 95% increases the manpower and material costs of the reproductive center laboratory.

[0010] Therefore, the above-mentioned prior art has at least the following technical problems: the use of alcohol lamps in the prior art to make Pasteur pipettes has serious safety hazards, affects the air quality of the embryo laboratory, and increases management costs. Utility Model Content

[0054] The embodiment of the present application provides a heating device for Pasteur pipettes, thereby solving the technical problems in the prior art of using alcohol lamps to make Pasteur pipettes, which has serious safety hazards, affects the air quality of the embryo laboratory, and increases management costs.

[0055] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0056] One or more embodiments of the present application provide a heating device for Pasteur pipettes, which is used in the embryo laboratory of a reproductive center to heat Pasteur pipettes during the process of making Pasteur pipettes with different inner diameters. Of course, the heating device can also be used in other occasions, which is not limited here.

[0057] like Figures 1 to 5 As shown, the heating device comprises:

[0058] Base 100;

[0059] A first electric soldering iron 200, which is fixedly disposed on the base 100, and includes a first soldering iron head 210, the first soldering iron head 210 is exposed from the base 100, and after the first electric soldering iron 200 is powered on, the first soldering iron head 210 can be used to heat the Pasteur pipette;

[0060] The first temperature regulator 230 is disposed on the base 100 and is used to adjust the temperature of the first soldering iron tip 210 .

[0061] From the above description, it can be known that the heating device described in the embodiment of the present application is provided with a base 100 that can be stably placed on a work surface, and a first electric soldering iron 200 that can be connected to a power source is fixedly provided on the base 100, so that the first electric soldering iron 200 can be stabilized on the work surface. When the electric soldering iron is powered on, the temperature rises and can be used to heat Pasteur pipettes, that is, to replace the alcohol lamp in the embryo laboratory of the reproductive center to burn Pasteur pipettes of different inner diameters. Since the heating device is based on electric heating, no alcohol is required, no ignition is required, and no combustion occurs, so it is very safe and will not affect the air quality of the embryo laboratory. In addition, after the use of the heating device, the power supply can be disconnected, and no additional storage management is required, which reduces management pressure and cost. In addition, the first temperature regulator 230 can adjust the temperature of the first soldering iron tip 210, which can not only meet specific temperature requirements, but also avoid excessive temperature, further improve safety and practicality, and effectively solve the technical problems in the prior art of using alcohol lamps to make Pasteur pipettes, which have serious safety hazards, affect the air quality of the embryo laboratory, and increase management costs, thereby achieving the beneficial effects of safety, convenience, and low management costs.

[0062] In one embodiment of the present application, Figures 1 to 5 As shown, the heating device also includes:

[0063] A second electric soldering iron 300 is fixed on the base 100 and spaced apart from the first electric soldering iron 200. The second electric soldering iron 300 includes a second soldering iron head 310. The second soldering iron head 310 is exposed from the base 100. After the second soldering iron head 310 is powered on, the second soldering iron head 310 can be used to heat the Pasteur pipette.

[0064] The second temperature regulator 330 is used to adjust the temperature of the second soldering iron tip 310 .

[0065] Specifically, the embodiment of the present application sets up two electric soldering irons, namely a first electric soldering iron 200 and a second electric soldering iron 300, and configures them with temperature regulators respectively. In this way, the temperature of the first soldering iron head 210 and the second soldering iron head 310 can be controlled by pre-adjusting the corresponding temperature regulators, so that one of the electric soldering irons (such as the first electric soldering iron 200) is used to replace the outer flame of the alcohol lamp, and the other electric soldering iron (such as the second electric soldering iron 300) is used to replace the outer flame of the alcohol lamp, which are respectively used for the two steps of melting the Pasteur pipette and ironing the cut end of the Pasteur pipette. In this way, the original operating habits of the embryo laboratory of the reproductive center are not destroyed, the operating pressure of the laboratory personnel can be reduced, the practicality is very strong, and there is no need to repeatedly adjust the temperature regulator, and the operation can be directly streamlined, which can effectively improve work efficiency.

[0066] For example, when the heating device is required to be as consistent as possible with the existing alcohol lamp, the temperature of the first soldering iron tip 210 can be adjusted to about 665°C, and the temperature of the second soldering iron tip 310 can be adjusted to about 520°C. Of course, the first soldering iron tip 210 and the second soldering iron tip 310 can also be adjusted to other temperatures to meet specific needs, which is not limited here. It can be seen that the heating device described in the embodiment of the present application is more flexible in temperature adjustment and more convenient to use than the alcohol lamp in the prior art.

[0067] In one embodiment of the present application, Figure 1 , 2 As shown in Figure 5, the first soldering iron tip 210 is in a U-shape with its opening facing upward.

[0069] In one embodiment of the present application, Figure 1 , 2 As shown in Figure 5, at least one outer side surface of the second soldering iron tip 310 is a plane.

[0070] Specifically, the second soldering iron tip 310 is used to replace the inner flame of the alcohol lamp and is needed to iron the cut end of the Pasteur straw until it is smooth. Therefore, at least one outer side surface of the second soldering iron tip 310 is designed to be a plane, and the cut end of the Pasteur straw can be directly pressed against the plane for ironing, which is very convenient and easy to use.

[0071] Furthermore, the second soldering iron tip 310 is in a rectangular parallelepiped or a cube shape, so that the side surfaces of the second soldering iron tip 310 are all flat surfaces, which can be freely selected by laboratory personnel and is very convenient and easy to use.

[0072] In one embodiment of the present application, Figure 1 ,2 As shown in FIG. 5 , the height of the first soldering tip 210 on the base 100 is higher than the height of the second soldering tip 310 on the base 100. Thus, the first soldering tip 210 used to replace the outer flame of the alcohol lamp is higher than the second soldering tip 310 used to replace the inner flame of the alcohol lamp. The higher soldering tip corresponds to the outer flame, and the lower soldering tip corresponds to the inner flame, which conforms to the actual situation of the inner and outer flames of the alcohol lamp, can play an effective prompting role, avoids confusion among laboratory personnel, and is very practical.

The first heating element, the second heating element, the first soldering iron tip 210, and the second soldering iron tip 310 can adopt the common structure and material of the electric soldering iron in the prior art, for example: the first soldering iron tip 210 and the second soldering iron tip 310 can be made of copper, tungsten-copper alloy, nickel-iron alloy, etc.; the first heating element and the second heating element can be made of ferritic stainless steel, tungsten, nickel-chromium alloy, iron, copper, etc., which are not limited here.

[0083] Specifically, the first electric soldering iron 200 and the second electric soldering iron 300 can be started or shut down through the control of the first switch 120 to meet specific needs and improve safety in use.

[0084] In one embodiment of the present application, Figures 1 to 5 As shown, the heating device also includes:
