Description

Technical Field

[0002] During the in vitro embryo research of mammals, scientific researchers and technicians need to operate on eggs or embryonic cells (hereinafter referred to as "cells"), perform routine experimental operations such as transfer between different culture media, cleaning after IVF, and transplantation in vivo. In order to prevent the cells from being contaminated, ensure a high success rate of the experiment, and the safety of the researchers themselves, the above experimental sites need to be selected in a barrier environment or an experimental environment with a higher cleanliness level, and scientific researchers are required to wear masks for experimental operations. At present, researchers perform cell operations with homemade straight-through mouth pipettes, and they must take off their masks when using them. Hold one end of the mouth pipette in your mouth, and use your mouth to blow / inhale air into the front end of the mouth pipette to control the transfer or cleaning of cells at the other end of the mouth pipette. Normally, the time for cell manipulation without a mask is at least ten minutes. Long-term accumulation may affect the safety level control level required for the experiment, which will conflict with the relevant regulations of the experimental site. If the mouth pipette-related experiments are performed in large quantities and for a long time, the entire laboratory environment may not be able to maintain the safety level required for the experiment, resulting in cell contamination and low experimental success rate. In severe cases, it may also pose a hidden danger to the health of scientific researchers. Summary of the invention

[0022] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are 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. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention.

[0023] See also Figure 1 , a mouth-suction type operator, consists of three parts: a mouth-suction section at the front end, a connecting section at the middle end, and a suction / outlet section at the rear end.

[0024] The mouth suction section includes a straight round tube 1, an oblique tube 7 and a filter 2, one end of the straight round tube 1 is connected to one end of the filter 2, the other end of the straight round tube 1 is connected to one end of the oblique tube 7, and there is an angle of less than 90° between the straight round tube 1 and the oblique tube 7. The connecting section includes a hose 3, which is a rubber hose. One end of the hose 3 is connected to the other end of the filter 2, and the suction / exhaust section includes a hard connecting tube 4, one end of the hard connecting tube 4 is connected to the other end of the hose 3, and the other end is connected to a rubber stopper 5, the center of the rubber stopper 5 is provided with an insertion hole, and a glass needle 6 is inserted into the insertion hole.

[0025] During the in vitro embryo research of mammals, scientific and technical personnel need to transfer eggs or embryonic cells between different culture media, clean them after IVF, transplant them in vivo, and other routine experimental operations. In the specific cell operation experiment, there is no need to take off the mask when using it. The three parts of the mouth suction section at the front end, the connecting section at the middle end, and the suction / exhaust section at the rear end are connected, and the mouth suction device is inserted from the bottom edge of the mask and hung in the mouth. The scientific and technical personnel hold one end of the inclined tube 7 in the mouth and use the mouth to blow / inhale air into the mouth suction tube. The airflow passes through the inclined tube 7, the straight round tube 1, the filter 2, the hose 3, the hard connecting tube 4 and the glass needle 6 in sequence to control the entry and exit, transfer, cleaning or transplantation of cells at the other end of the mouth suction tube. Usually, in a complete cell experimental operation process, water vapor in the airflow enters the filter 2, and the filter 2 filters the water vapor. This prevents saliva and water vapor from clogging the mouth straw, and the airflow is stable during the experimental operation. Researchers can use the mouth suction manipulator to perform various cell operations without removing the mask, thereby achieving a high level of maintenance of the experimental environment, efficiently achieving the experimental objectives, and ensuring the physical safety of the researchers themselves.

[0026] As a preferred embodiment of the present invention, see Figure 1 There is an angle of 70° to 80° between the straight round tube and the oblique tube, so that the oblique tube can be hung in the mouth. Furthermore, the connection between the oblique tube and the straight round tube is rounded, and the turning point can better achieve airflow stability, and it is not easy to fall off during breathing.

[0027] As a preferred embodiment of the present invention, see Figure 1 The oblique tube 7 is an oblate tube, which is placed in the operator's mouth to increase comfort. Its thickness gradually decreases from the end to the root, so there is no need to worry about the oblique tube 7 slipping out of the mouth, and the operator can use both hands to perform other operations.

[0028] As a preferred embodiment of the present invention, see Figure 2 The filter 2 is used to filter water vapor in the airflow, and includes an upper cover 8 and a lower cover 9, which are connected by threads, and a cavity is formed inside the upper cover 8 and the lower cover 9, and a breathable filter material 10 is arranged in the cavity, and the breathable filter material 10 includes a spunbond non-woven fabric layer and a melt-blown non-woven fabric layer. The spunbond non-woven fabric is close to the upper cover, and the spunbond non-woven fabric has a water-blocking function, while the melt-blown non-woven fabric is made of a polypropylene material with a high melt index fiber, and is an ultra-fine electrostatic fiber cloth that can effectively use static electricity to absorb virus dust and droplets.

[0029] As a preferred embodiment of the present invention, see Figure 1 The upper cover 8 and the lower cover 9 of the filter 2 are provided with connecting pipes, and the connecting pipes of the upper cover 9 and the lower cover 10 are respectively plug-connected with the straight round pipe 1 and the hose 3.

[0030] As a preferred embodiment of the present invention, the straight round tube 1 is provided with a connecting end at one end connected to the filter 2, and the outer diameter of the connecting end is smaller than the outer diameter of the straight round tube 1, so that the hose 3 can be sleeved on the connecting end. The hose 3 is about 15-20cm long, 7mm in diameter, and 5mm in inner diameter, which can ensure stable airflow.

[0031] The straight round tube 1 and the oblique tube 7 are made of PPSU material, which can withstand high temperature sterilization and can be reused. There is a small hole in the middle of the rubber stopper 5, which can stably support the glass needle when inserted into it to achieve sealing. The glass capillary is a conventional consumable product. The glass needle can be drawn under an alcohol lamp, and the inner diameter of the tip can be enough to absorb mouse or rat embryonic cells.
