Description

Technical Field

[0001] The utility model belongs to the technical field of embryo manipulation equipment, and in particular relates to a mask used for embryo manipulation. Background Art

[0002] In embryo manipulation experiments on rodents such as mice and rats, including in vitro fertilization, embryo selection, embryo washing, embryo transfer, embryo freezing and resuscitation, the most widely used tool is a homemade simple egg transfer connection tube. The simple egg transfer connection tube mainly consists of two sections of silicone tubes and a filter in the middle. Among them, a plastic pipette tip (blue or yellow tip) is inserted on the thick silicone tube, and the thin end is connected to a glass egg transfer needle. When using it, bite the plastic pipette tip with your mouth, hold the upper end of the glass needle with your right hand, and control the glass needle to suck and spit out the embryo through the inhalation and exhalation of the mouth to realize the operation of the embryo experiment. When using this simple mouth pipette device, you need to take off the mask, expose your mouth and nose completely, and bite the tip with your mouth. The human mouth contains a lot of bacteria. Taking off the mask brings uncertain contamination risks to the embryo operation room that requires sterile operation, and also brings contamination risks to the internal barrier area of ​​the embryo operation laboratory.

[0003] A Chinese patent with publication number "CN208454969U" discloses a novel embryo manipulation oral suction tube, comprising an egg transfer needle, a connecting tube and an oral suction nozzle connected in sequence, the three of which are sleeved together, detachable, and the connection is sealed; the connecting tube comprises a plurality of connecting parts and a filtering device, a groove cavity is provided in the connecting part, the groove cavity passes through the connecting part, an annular structure is provided at the connection between the connecting part and the egg transfer needle, which is used for reinforcing the seal between the egg transfer needle and the connecting part, a filtering device is provided at the adjacent connecting part, a hollow protrusion is provided on the outside of the filtering device, the hollow protrusion is sleeved together with the groove cavity, and the filtering device and the connecting part are detachable; the oral suction nozzle comprises an oral suction part, a bending part and an extension part connected in sequence, the three of which are provided with a through cavity, the oral suction part is in contact with the mouth part, the two ends of the bending part form an acute angle or a right angle, and the extension part is sleeved together with the connecting part.

[0004] The above patent changes the shape of the nozzle into an "L" structure. During operation, the mouth bites the short end of the "L" and extends into the mask, while the long end extends vertically out of the mask and connects to the silicone connecting tube. The device does not require the mask to be removed during operation, but the nozzle extends from the lower end of the mask, causing the mask to not be completely sealed. During operation, the air in the mouth will still be discharged into the clean laboratory. At the same time, because the mask is not completely sealed, the hot air exhaled from the mouth during the use of the nozzle will rush to the glasses, causing blur, interfering with the experiment, and causing trouble for technicians wearing glasses.

[0024] The utility model will be further described below in conjunction with the accompanying drawings.

[0025] like Figure 1-3As shown, a mask for embryo manipulation includes a mask body 1, an egg transfer connecting tube and a suction nozzle 3. The mask body 1 is divided into a mouth-shaped part corresponding to the user's mouth position, and a nose part corresponding to the user's nose position. Among them, a plastic two-way tube 2 is embedded in the mouth-shaped part of the mask body 1. The inner end of the suction nozzle 3 is sleeved on the inner end of the plastic two-way tube 2. The outer end of the plastic two-way tube 2 is connected to the egg transfer connecting tube.

[0026] Specifically, if Figure 1 and 2 As shown, the plastic two-way tube 2 runs through the mouth-shaped part of the mask body 1. An air filter core is arranged inside the plastic two-way tube 2 to buffer the airflow in the mouthpiece 3; at the same time, the gas in the oral cavity is filtered to avoid the contamination of oocytes and in vitro embryos, improve the hygiene during the operation, and ensure aseptic operation. The plastic two-way tube 2 is divided into an internal connecting section 2-1 located on the inside of the mask body 1 and an external connecting section 2-2 located on the outside of the mask body 1. Among them, the length of the external connecting section 2-2 is 15-20mm and the outer diameter is 8-10mm. The length of the internal connecting section 2-1 is 8-10mm and the outer diameter is 7-11mm. The outer edges of the internal connecting section 2-1 and the external connecting section 2-2 are both provided with annular protrusions 2-3 to ensure the sealing of the connecting ends when the internal connecting section 2-1 and the external connecting section 2-2 are connected to the mouthpiece 3 and the egg transfer connecting tube.

[0027] like Figure 3 As shown, the two ends of the nozzle 3 are respectively a connection end close to the plastic two-way tube 2 and a bite end close to the user's mouth. The bite end of the nozzle 3 is provided with two circles of spaced arc-shaped protrusion structures 3-1 to assist the user's lips to prevent the nozzle 3 from slipping during use.

[0028] In this embodiment, the nozzle 3 is 15-20 mm long and hollow inside, with an outer diameter of 7-10 mm and an inner diameter of 3-6 mm. The nozzle 3 is made of silicone material and has good elasticity, so that its inner diameter can expand outward by 4-5 mm. When the silicone nozzle 3 is connected to the plastic two-way tube 2, the inner end of the nozzle 3 is turned outward so that it can be sleeved on the plastic two-way tube 2.

[0029] The egg transfer connecting tube includes a first connecting tube, a filter and a second connecting tube which are connected in sequence. In the present embodiment, the filter adopts a 0.22 micron filter. The two ends of the filter are respectively an inlet end close to one end of the mask body 1, and an outlet end close to one end of the egg transfer needle. Among them, the outer diameter of the inlet end of the filter is 8mm, and the outer diameter of the outlet end is 3-5mm. The first connecting tube and the second connecting tube are both made of silicone. The two ends of the first connecting tube are respectively connected to the inlet end of the filter and the end of the external connecting section 2-2 of the plastic two-way tube 2, and its inner diameter is 3.2mm and the outer diameter is 6.4mm. The inner end of the second connecting tube is connected to the outlet end of the filter, and its inner diameter is 2.4mm and the outer diameter is 5.6mm. The outer end of the second connecting tube is connected to the egg transfer needle.

[0030] When in use, the user wears the mask body 1 and puts the inner end of the nozzle 3 into the mouth. The user's lips are placed on the arc-shaped convex structure 3-1 on the nozzle 3, and the embryo operation is achieved by controlling the egg transfer needle and inhaling or exhaling with the mouth.

[0031] In addition, in this embodiment, the mask body 1 is provided with exhaust holes 1-1 on both sides of the mouth, and air inlet holes 1-2 on both sides of the nose. Air filter membranes are provided on the exhaust holes 1-1 and the air inlet holes 1-2. The provision of the air inlet holes 1-2 and the exhaust holes 1-1 helps the user breathe smoothly, thereby facilitating the completion of a long-term embryo manipulation experiment.
