The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Referring to fig. 1 to 3, the syringe suction assisting device for the novel coronavirus pneumonia vaccine of the present application comprises a protective sleeve 1, an elastic sealing ring 2, a sealing member 3, a first membrane 4 and a second membrane 5.

As shown in fig. 1, an elastic sealing ring 2 capable of sleeving an opening of an ampoule 11 is arranged on the edge of the inner wall of one end of the protecting sleeve 1, and a sealing element 3 is arranged at the other end.

The protective sleeve 1 comprises a cylinder 101 and a fixing part 102 which gradually shrinks towards the axial direction of the cylinder 101 along the length direction of the cylinder 101, and an elastic sealing ring 2 is arranged on the inner wall of one end of the fixing part 102 far away from the cylinder 101.

The elastic sealing ring 2 arranged at the edge of the inner wall of the fixing piece 102 has certain elasticity, before the protecting sleeve 1 is sleeved on the opening of the ampoule 11, the elastic sealing ring 2 is firstly opened, and the elastic sealing ring 2 is sleeved on the connecting position of the opening of the ampoule 11 and the main body of the ampoule 11. The fixing member 102 is sleeved on the opening of the ampoule 11, so that the protecting sleeve 1 can be fixed on the ampoule 11. And the sleeving position of the protective sleeve 1 and the ampoule 11 can be sealed to form a sealing structure.

As can be seen from the above, when the fixing member 102 is sleeved on the opening of the ampoule 11, the fixing member 102 needs to be spread, and therefore, the fixing member 102 is made of a plastic material with certain elasticity. Whether the cylinder 101 needs to have elasticity to cover the opening of the ampoule 11 or not has no influence, so the cylinder 101 can be made of glass, and in addition, because the first film 4, the second film 5 and the cylinder 101 need to form a sealing structure, the glass cylinder 101 has no deformation, and the edges of the first film 4 and the second film 5 can be stably connected with the cylinder 101.

It should be noted that, the tube 101 may also be made of the same material as the fixing member 102, when the same material is selected, in order to avoid deformation of the fixing member 102 when the fixing member 102 is sleeved and spread, the first annular reinforcing rib 6 is disposed at a position of the tube 101 close to the fixing member 102, and the first annular reinforcing rib 6 is fixedly connected to the tube 101, so that when the fixing member 102 is spread and deformed, the first annular reinforcing rib 6 can form a shaping effect on the tube 101, and the tube 101 cannot be deformed along with deformation of the fixing member 102.

Further, the elastic sealing ring 2 may be a rubber ring.

As shown in fig. 2, in addition, in order to improve the sealing effect of the elastic sealing ring 2, at least one circumferentially arranged groove 7 is arranged on the inner wall of the elastic sealing ring 2, and two sealing structures are formed by using the opposite side walls of the groove 7, so that even if the first sealing structure leaks air, the second sealing structure can still ensure the sealing effect of the sealing structure.

Sealing member 3, lag 1 and ampoule 11 make the interior airtight structure that forms of lag 1, with inside and outside isolated of lag 1.

In order to facilitate the syringe 12 to be able to pass through the seal 3, the material of the seal 3 is rubber. The rubber structure of the sealing member 3 is utilized to enable the syringe 12 to penetrate through the sealing member 3 and to seal the joint of the syringe 12 and the sealing member 3.

In particular, the shape of the sealing element 3 may be set as desired, for example, the sealing element 3 may be a sealing plug or a sealing cover, wherein the sealing plug is at least partially disposed within the shield 1 and plugs the port of the shield 1. Or, the sealing element 3 is a sealing cover which is arranged at the port of the protective sleeve 1 in a covering manner, and the port of the protective sleeve 1 is sealed by using the elasticity of rubber.

Secondly, the circumferential edges of the first membrane 4 and the second membrane are respectively connected with the inner wall of the protecting sleeve 1 in the circumferential direction, and the first membrane, the protecting sleeve 1 and the second membrane 5 form a first negative pressure cavity.

The first film 4 and the second film 5 are made of a material that can be pierced by the syringe 12, for example, the first film 4 and the second film 5 are made of a rubber film and an aluminum foil.

It will be understood that the rubber membrane has a relatively thin thickness so that in case of puncture by the syringe 12, the negative pressure can be diffused towards the inside of the protector 1, i.e. after the first membrane 4 and the second membrane 5 have been punctured, the air in the protector 1 enters the negative pressure chamber due to the first negative pressure chamber, so that the protector 1 has a certain negative pressure.

For the above reasons, the thickness of the rubber film may take any value of 1 to 2 mm.

It can also be understood that although the sealing member 3 and the first and

second films

4 and 5 are made of the same rubber material, the sealing member 3 is thicker than the first and

second films

4 and 5, so that the connection position of the first and

second films

4 and 5 and the syringe 12 does not form a sealed structure after the first and

second films

4 and 5 are pierced, but the sealing member 3 can form a sealed structure.

In addition, the first membrane 4 and the second membrane 5 may also be made of aluminum foil which is easy to puncture, so as to further facilitate the air inside the protective sleeve 1 to enter the first negative pressure cavity, and after the syringe 12 punctures the first membrane 4 and the second membrane 5 of the aluminum foil, the syringe may be appropriately twisted inside the protective sleeve 1, so as to enlarge the hole where the aluminum foil is punctured.

In this embodiment, the syringe 12 of the syringe suction assisting device for the novel coronavirus pneumonia vaccine can penetrate through the sealing member 3 and pierce the first membrane 4 and the second membrane, so that the negative pressure in the first negative pressure cavity is diffused to the region surrounded by the protective sleeve 1, the sealing member 3 and the ampoule 11 to form a second negative pressure cavity. When the syringe 12 with novel coronavirus vaccine suction in ampoule 11 to syringe 12 in, take partial syringe 12 out next for syringe 12's syringe needle can be stayed in lag 1, then, promote syringe 12, with the air discharge in the syringe 12 in lag 1, because have certain negative pressure in lag 1, not only make things convenient for the air to emit into, can also avoid when injecting air into lag 1, form the malleation in lag 1, the air is by lag 1 and ampoule 11 hookup location or syringe needle and the 3 hookup location exhaust possibility of sealing member.

In one embodiment, as shown in figure 3, the end of the fixing member 102 remote from the barrel 101 has an outwardly turned outer rim 8.

In order to facilitate the fixing member 102 to be sleeved on the bottleneck of the ampoule 11, the outer edge 8 of the fixing member 102 is provided with an outward-turned outer edge 8 at the edge thereof, which is convenient for a user to pull, so that the open end of the fixing member 102 is expanded.

Because the fixing member 102 has certain flexibility, in order to further facilitate the user to pull the outer rim 8, a second annular reinforcing rib 9 is provided at the outer rim 8, and the second annular reinforcing rib 9 can be provided on the outer wall or the inner wall of the outer rim 8.

The user can hold the second annular reinforcing rib 9 by hand, align the opening of the ampoule 11 and then move the ampoule to the ampoule 11, because the shape of the outer edge 8 is fixed by the second annular reinforcing rib 9.

It will be appreciated that the outer rim 8 provided with the second annular bead 9 may be understood as a truncated cone.

In one embodiment, the syringe suction auxiliary device for the novel coronavirus pneumonia vaccine further comprises an annular piece 13, wherein one end face of the annular piece 13 is provided with a first film, and the other end face of the annular piece 13 is provided with a second film; the annular piece 13 is arranged in the protecting sleeve 1 and is in interference fit with the protecting sleeve 1.

The ring member 13 is made of glass or hard plastic.

The ring-shaped member 13 has one end connected to the edge of the first membrane 4 and the other end connected to the edge of the second membrane 5, so that the ring-shaped member 13, the first membrane 4 and the second membrane 5 form a columnar structure.

The annular member 13, the first membrane 4 and the second membrane 5 form a first underpressure chamber.

The outer diameter of the ring 13 is slightly larger than the inner circumferential wall of the cylinder 101 so that the ring 13 is interference-fitted with the cylinder 101.

Utilize annular member 13, first membrane 4 and second membrane 5 to form the column structure, can make things convenient for mill's processing, mill process respectively lag 1 and column structure's annular member 13, first membrane 4 and second membrane 5, then cup joint can, reduced the degree of difficulty of mill's processing.

When the ring-shaped member 13 is not in interference fit with the cylindrical member 101, the limiting protrusion 10 may be provided on the inner wall of the cylindrical member 101, and when the ring-shaped member 13 is placed on the cylindrical member 101, one end of the ring-shaped member 13 close to the fixing member 102 may abut against the limiting protrusion 10, and the limiting protrusion 10 may prevent the ring-shaped member 13 from moving further in the direction of the elastic sealing ring 2.

For example, during the process of inserting the needle of the syringe 12 into the ring-shaped member 13, the limiting protrusions 10 can prevent the ring-shaped member 13 from moving further toward the fixing element 102, so that the needle of the syringe 12 can pierce the first film 4 and the second film 5.

In summary, the fixing member 102 of the protecting sleeve 1 is sleeved on the bottleneck of the ampoule 11. When the needle of the syringe 12 is inserted into the sealing element 3, the needle and the sealing element 3 form a closed structure, the needle continuously moves towards the first membrane 4 and the second membrane 5 and is sequentially punctured, and because the first membrane 4, the second membrane 5 and the cylindrical member 101 of the protective sleeve 1 form a first negative pressure cavity, when the first negative pressure cavity is punctured, air in the protective sleeve 1 enters the first negative pressure cavity, so that a second negative pressure cavity is formed in the protective sleeve 1.

After ampoule 11 is pierced to the syringe needle of syringe 12, in novel coronavirus vaccine suction syringe 12, extract the syringe needle, make the syringe needle stay in lag 1, the inside air of evacuation syringe 12 next, the air passes through the syringe needle and emits into in lag 1, because be the second negative pressure chamber in lag 1, the air can become positive ordinary pressure by the negative pressure in making lag 1, if originally in lag 1 under the condition of positive ordinary pressure, when the air of emitting into in lag 1 again, can make and form the malleation in lag 1, this kind of condition, cause the air to be arranged to the external world by
