Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 to 6, the present invention provides a technical solution: dampproofing antioxidative medical rubber buffer, including filling in post 1, fill in post 1 and be frustum shape, fill in post 1 and be the diameter by the high circle that reduces gradually to the low cross section, the bottom fixedly connected with rubber back-off portion 2 of filling in post 1, rubber back-off portion 2 is down the mushroom shape, the mushroom top of rubber back-off portion 2 sets up to the cambered surface calotte, the cross section diameter of rubber back-off portion 2 is greater than the cross section maximum diameter of filling in post 1, fill in when post 1 and rubber back-off portion 2 fill in the bottleneck, rubber back-off portion 2 can be compressed and produce deformation, fill in to the bottle in the lowest department that releases deformation potential energy and seal the bottleneck until rubber back-off portion 2, the outer wall of filling in post 1 also can be compressed and to the bottleneck inner wall release deformation potential energy.

When filling in post 1 and rubber back-off portion 2 and filling in to the bottleneck inner wall, when the junction in rubber back-off portion 2 reachs bottleneck and bottle, the user can experience and fill in the pressure reduction this moment, can try upwards to extract to fill in post 1 this moment, if extract obstructed, can prove that rubber back-off portion 2 reachs the junction of bottleneck and body inside, through the power of upwards extracting, make the top of rubber back-off portion 2 inconsistent with the bottom of bottleneck, thereby can rubber back-off portion 2 seal bottleneck bottom, and the part outer wall of filling in post 1 this moment equally enters into to bottleneck inside, release deformation potential energy simultaneously and seal the bottleneck inner wall, and make the installation that fills in post 1 and rubber back-off portion 2 and can fix in the bottleneck.

Through rubber back-off portion 2 and the deformation cooperation of filling in post 1, can seal the bottleneck bottom and the bottleneck inside of sealed bottle, realized that the duality is sealed, and can also guarantee to fill in post 1 and rubber back-off portion 2 and install the intraoral steadiness at the bottleneck, prevent to fill in post 1 and be extracted at will.

Further, the outer wall of filling in post 1 still sliding connection has rubber seal ring 3, rubber seal ring 3 is the ring form, when rubber seal ring 3 upwards slides along the outer wall of filling in post 1, the inner wall of rubber seal ring 3 with fill in 1 outer wall of post and can closely laminate and form sealing connection department, the ring portion of rubber seal ring 3 is greater than the bottleneck of sealed bottle, when filling in post 1 and fill in the bottleneck, the bottom and the bottleneck top contact of rubber seal ring 3, and rubber seal ring 3 can be by vertical compression deformation, when 2 reachs preset positions in rubber back-off portion, 3 release deformation potential energy of rubber seal ring seal bottleneck and with the fixed post 1 that fills in of the deformation potential energy cooperation that 2 produced in rubber back-off portion.

By arranging the rubber sealing ring 3, when the plugged column 1 is plugged into the bottleneck, the bottom of the rubber sealing ring 3 is enabled to be abutted against the top of the bottleneck, and the rubber sealing ring 3 can be gradually deformed along with the fact that the plugged column 1 is continuously inserted into the bottleneck, thereby accumulating the deformation potential energy, when the release of the rubber back-off part 2 is completed, the bottom of the bottle mouth is closed, at the moment, the plug-in column 1 and the rubber sealing ring 3 stop, so that the plugged column 1 releases the deformation potential energy to cause pressure on the inner wall of the bottle mouth to complete the sealing of the bottle mouth, meanwhile, the rubber sealing ring 3 releases the deformation potential energy to enable the plugged column 1 to move upwards, but because rubber back-off portion 2 is to filling in post 1 and spacing, the deformation potential energy that rubber sealing ring 3 produced except causing the extrusion and sealing the bottleneck top to the bottleneck top, can also make the top of rubber back-off portion 2 inseparabler with the bottom contact of bottleneck.

Therefore, through the rubber sealing ring 3 all the time, the rubber sealing ring 3 can seal the top of the bottle mouth and can also strengthen the sealing of the top of the rubber reverse-buckling part 2 to the bottom of the bottle mouth.

Through the cooperation of filling in post 1, rubber back-off portion 2 and rubber seal ring 3, can all form sealed fixed, the sealed bottleneck of full aspect to bottom, inner wall and the top of bottleneck.

Further, fill in the bottom of post 1 and seted up guide way 7, decompression groove 8 has been seted up at the top of rubber back-off portion 2, guide way 7 is linked together with decompression groove 8, and the groove cross-section of guide way 7 and decompression groove 8 is equal circle, through setting up guide way 7, for the deformation of filling in post 1 provides the preparation space, the outside medical instrument's of being convenient for simultaneously puncture, for example, the syringe needle, prevent that deep syringe needle from causing the jam, through setting up decompression groove 8, inside tools such as syringe needle pierce rubber back-off portion 2 until reaching the body, can prevent to take away needle wall residue when syringe needle outwards extracts through decompression groove 8's bottom.

Further, fill in the top fixedly connected with top cap 4 of post 1, the diameter of top cap 4 bottom is greater than the diameter of filling in the top of post 1, and through setting up top cap 4, convenient to use person presses top cap 4 top and will fill in post 1 and rubber back-off portion 2 and fill in the bottleneck, also can convenient to use person will fill in post 1 and rubber back-off portion 2 simultaneously and extract.

Further, the inner wall fixedly connected with detection part 6 of guide way 7, and leave the space between the top of detection part 6 and the interior bottom of guide way 7, through setting up detection part 6, when the syringe needle pierces inside guide way 7 when contact detection part 6, make the user know the inserted position of syringe needle, the correct prediction of convenient to use person is inserted the distance.

Secondly, when filling in post 1 and 2 live time overlengths of rubber back-off portion, and when unable extracting, accessible barb instrument pierces to inside 7 guide ways, perhaps pierces to 2 bottoms of rubber back-off portion, then will fill in post 1 and 2 extracts of rubber back-off portion through external force.

Further, the top of the top cover 4 is provided with a guide part 5, the center of the top of the guide part 5 is depressed downwards, the guide part 5 is positioned at the center of the top of the inserted column 1, and meanwhile, the guide part 5 is positioned right above the guide groove 7, so that the guide groove 7 and the decompression groove 8 are determined for a user, and the puncturing position is determined.

Further, the top edge of rubber back-off portion 2 is provided with the chamfer, when the post 1 when will filling in when extracting as required, the top and the bottleneck bottom of the rubber back-off portion 2 of being convenient for to the contact, the rubber back-off portion 2 of being convenient for gets into to the bottleneck inner wall.

Further, rubber seal ring 3 to top cap 4 direction friction slip to extreme position between and the bottom of top cap 4 leave the space, make the user can utilize top cap 4 and the contact department of plugging in post 1, the plug of being convenient for.

To sum up, the utility model discloses can all form sealed fixed, the sealed bottleneck of three aspect to bottom, inner wall and the top of bottleneck when inserting the bottleneck.
