Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention so that the technical solution of the present invention can be more easily understood and grasped, and should not be construed as limiting the present invention.

Example (b):

a dispenser, shown with reference to FIGS. 1 and 2, includes a lower case 1, an upper case 2, and a core pack 3 installed inside the upper case 2 and the lower case 1. The lower shell 1 comprises a puncture needle 11, a ventilation part 12 which is positioned above the puncture needle 11 and is integrally connected, a mounting seat 13 which is positioned above the ventilation part 12 and is integrally connected, and a hand-held part 14 which is positioned at two sides of the mounting seat 13 and is integrally connected and used for buckling the bottle mouth. The outer side surface of the hand-held portion 14 is provided with a plurality of anti-slip convex strips 141. Convenient for finger operation and not easy to slip. The sharp portion of the puncture needle 11 faces downward. A stopper 17 is provided on the puncture needle 11 below the vent 12, and the stopper 17 is plate-shaped and perpendicular to the puncture direction of the puncture needle 11. The stopper 17 has a disk-like shape, and can restrict the insertion depth of the puncture needle 11, thereby allowing the determination of the insertion position and facilitating the operation.

Referring to fig. 3, a first passage 15 is provided in the puncture needle 11 to both sides of the vent portion 12, and a second passage 16 is provided in the puncture needle 11 to the center of the mount 13.

The upper housing 2 is fixedly connected to the mounting base 13.

The core group 3 comprises a built-in needle tube 31, an upper silica gel sleeve 32 sleeved on the upper end of the built-in needle tube 31, and a lower silica gel sleeve 33 sleeved on the lower end of the built-in needle tube 31. The upper silica gel sleeve 32 realizes the sealing between the built-in needle tube 31 and the upper shell 2, the lower silica gel sleeve 33 realizes the sealing between the built-in needle tube 31 and the mounting seat 13, and the middle part is provided with a layer of liquid medicine filtering membrane 9, namely, the liquid medicine flows between the annular convex strips to play a filtering role, but the filtering area is not influenced. The lower end of the built-in needle tube 31 is of a tapered configuration and is inserted into the upper end of the second passage 16 during the downward movement. The tapered configuration facilitates movement and relatively stable direction of movement of the inner needle cannula 31, effectively extending into the upper end of the second passageway 16.

The vent part 12 has a first mounting end 121, the first mounting end 121 is fixedly inserted with a bowl-shaped member 4, the opening of the bowl-shaped member 4 is fixedly connected with a capsule 5, and the bowl-shaped member 4 has an air port 41 connected with the first channel 15. An air filter membrane 7 is fixed to the air port 41. The air filtration membrane 7 is formed by combining paper and PTFE. The function of the air filter membrane 7 is to filter air as well as dust or plastic particles. The liquid medicine filtering membrane 9 is made of nylon, and is used for filtering liquid medicine and blocking plastic particles and the like. After the vent part 12 is connected to the bowl 4, the gas in the medical bottle is not easily leaked, and the internal pressure of the medical bottle is adjusted by the capsule 5 of the bowl 4. Namely: when the air in the medical bottle needs to be discharged, the air directly enters the bowl-shaped piece 4 through the first channel 15 via the air filtering membrane 7 (preventing the liquid medicine) and enters the bowl-shaped piece 4, and the capsule 5 is bulged; when the liquid medicine in the medical bottle is reduced and the air pressure is reduced, the air is reflowed to the medical bottle again through the bulged sac membrane 5.

The ventilation part 12 further has a second mounting end 122, the second mounting end 122 is fixedly connected with another air filtering membrane 7 and a silica gel one-way valve 6, and the silica gel one-way valve 6 is used for introducing air. Medical personnel use the liquid medicine and need use in stages, if cyst membrane 5 has been in when drawing in the state limit in, still need take out the liquid medicine from, still can produce the negative pressure in the medical bottle like this, for this reason, through the aforesaid setting, for the internal pressure of balanced medical bottle this moment, external air can pass through silica gel check valve 6 and air filter membrane 7, then enter into medical bottle through ventilation unit 12 and first passageway 15, the air reaches filtered air's mesh through air filter membrane 7 this moment, balanced atmospheric pressure and safe requirement have been satisfied simultaneously.

The upper surface of the mount 13 and the lower surface of the upper case 2 are each provided with an annular convex strip 131 fitted to each other. The annular strips are discontinuous. The annular convex strip 131 improves the reliability of assembly and increases the contact surface, and is convenient for residual liquid medicine on the built-in needle tube 31 or the lower silica gel sleeve 33 to stay on the mounting seat 13, thereby reducing the pollution to the built-in needle tube 31 and the medical bottle.

The working process is as follows: the puncture needle 11 is directly inserted into the medical bottle, the injector does not need to be matched with an injection needle head, the injector only needs to be inserted from the upper end of the upper shell 2, the end part of the injector extrudes the upper silica gel sleeve 32 at the moment, so that the built-in needle tube 31 is contacted and connected with the end part of the upper injector, the upper silica gel sleeve 32 deforms and can effectively seal an internal channel, the built-in needle tube 31 can further go deep into the second channel 16 after moving downwards, and at the moment, the air or the liquid medicine in the injector is isolated from the outside and can smoothly enter the medical bottle. At this time, the air pressure in the medical bottle is increased, the air in the medical bottle enters the ventilation part 12 through the first channel 15, and the ventilation part 12 is used for exhausting or sucking air, so that the internal pressure in the horizontal medical bottle can be quickly leveled, and the aim of saving labor is fulfilled. The hand-held portion 14 facilitates insertion and fastening of the puncture needle 11 into the medical bottle.

Example 2:

based on embodiment 1, the upper end portion of the upper shell 2 is a threaded section, and the difference from embodiment 1 is that: go up casing 2 and be provided with sealing 8 on the screw thread section, sealing 8 includes that an organic whole encircles protection seat 81 outside the screw thread section, an organic whole connects in protection seat 81 edge and the sealed lid 82 of bending connection, and sealed lid 82 is used for opening and close screw thread section and protection seat 81 opening. The reliability of the syringe connection can be improved. In addition, the sealing cover 82 can also protect the threaded section, the sealing cover 82 can be opened when the threaded section is needed to be used, and the sealing cover 82 can be closed when the threaded section is not needed to be used, so that air pollution to the threaded section can be reduced or avoided.

Of course, the above is only a typical example of the present invention, and besides, the present invention can also have other various specific embodiments, and all technical solutions adopting equivalent replacement or equivalent transformation are all within the scope of the present invention as claimed.
