Description

Technical Field

[0001] The utility model relates to a medical device, more specifically, to a novel environmentally friendly stacked suction head. Background Art

[0002] Pipette tips are tools needed in experiments and production in various chemical, biological research and other aspects. They are usually used in conjunction with pipettes. As disposable consumables, pipette tips are easy to process and cannot be reused. They are in great demand in chemical and biological experiments. In order to prevent the pipette tips from being contaminated and thus affecting the experimental data, the installation requirements for the pipette tips are high.

[0003] At present, most of the pipette tips on the market are individually packaged, and the demand for pipette tips is high during the experiment. They take up a lot of space, and after the use of the pipette tips, they are difficult to collect and process, causing great pollution to the environment. In addition, some unavoidable human secondary pollution may occur during the installation of the pipette tips, which will affect the hygiene requirements of the pipette tips. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a new type of environmentally friendly stackable suction head that can be stacked and easily installed.

[0005] To achieve the above objectives, the present invention provides the following technical solutions: a new type of environmentally friendly stackable suction head, which includes a suction head body and a connecting piece arranged on the top of the suction head body. A fixed base is also provided at the bottom of the suction head body, and a cavity adapted for the suction head is provided in the fixed base. The fixed base and the suction head are detachably connected, and the two adjacent suction heads are also detachably connected.

[0006] By adopting the above technical solution, the pipette tips can be stacked and stored, which effectively utilizes space and is convenient for storage and transportation. The stacked pipette tips take up less space, are easier to carry, and are convenient for use in different occasions.

[0007] The utility model is further configured as follows: the lower end of the connecting piece is provided with an external thread and the upper end of the connecting piece is provided with an internal thread, and the two adjacent suction heads are connected by threads, so that the adjacent suction heads are tightened by rotating clockwise and loosened by rotating counterclockwise.

[0008] By adopting the above technical solution, adjacent nozzles can be tightly connected together through threaded connection to ensure that they will not loosen easily during use. The design of clockwise rotation to tighten and counterclockwise rotation to loosen allows users to easily assemble and disassemble the nozzles, making them convenient for use and storage.

[0009] The utility model is further configured as follows: an internal thread that matches the external thread of the suction head is provided in the cavity of the fixed base, and the fixed base and the suction head are connected by threads, so that the suction head is installed in the cavity.

[0010] By adopting the above technical solution, the suction head is installed in the cavity, which can effectively save space and facilitate storage. The fixed base can play a certain protective role for the suction head. The suction head is set in the mounting piece. When the suction head is installed on the pipette gun, it is fixed by contacting the mounting piece to prevent direct contact with the suction head and causing secondary contamination of the suction head. In addition, used suction heads can be stacked through the mounting piece, with high connection strength, convenient recycling of the suction heads, and good environmental protection effect.

[0011] The present invention is further configured such that: the connecting piece and the suction head body are an integrally formed structure.

[0012] By adopting the above technical solution, one-piece molding can better ensure the sealing of the nozzle, reduce the assembly process, reduce production costs, and improve production efficiency; avoid quality problems caused by poor connection between the connector and the nozzle body, and improve the stability of product quality.

[0013] The utility model is further configured as follows: the bottom of the mounting base is provided with anti-slip lines.

[0014] By adopting the above technical solution, the anti-slip texture can increase the friction between the mounting base and the contact surface, making the suction head more stable when placed and not prone to sliding or tipping. When operating the suction head, the stability of the mounting base allows the user to operate more easily.

[0015] The utility model is further configured as follows: the suction head is made of degradable material.

[0016] By adopting the above technical solutions, it helps to reduce the generation of plastic waste, reduce pollution and comply with environmental protection requirements. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Reference Figures 1 to 4 The embodiment of the environmentally friendly stacked suction tips of the present invention is further described.

[0023] For ease of explanation, spatial relative terms such as "upper", "lower", "left", and "right" are used in the embodiments to illustrate the relationship between one element or feature shown in the figures and another element or feature. It should be understood that, in addition to the orientation shown in the figures, spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figure is inverted, the element described as being "under" other elements or features will be positioned "above" other elements or features. Therefore, the exemplary term "under" can include both upper and lower orientations. The device can be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used here can be interpreted accordingly.

[0024] Moreover, relational terms such as “first” and “second” are merely used to distinguish one component from another having the same name, but do not necessarily require or imply any actual relationship or order between these components.
