In the present application, the type and structure of components that are not specified are all the prior art known to those skilled in the art, and those skilled in the art can set the components according to the needs of the actual situation, and the embodiments of the present application are not specifically limited.

Example 1

This embodiment provides a pharmacy experiment sample injector, realizes through essential technical feature the utility model discloses to solve the problem that the technical background part proposed in this application file.

Specifically, as shown in fig. 1-2, the embodiment of the present invention provides a pharmaceutical experiment sampler, which comprises a cylindrical casing 7, wherein a plurality of first through openings are uniformly formed at the bottom of the casing 7, a plurality of second through openings 14 are uniformly formed at the top of the casing 7, the second through openings 14 are equal in number and correspond to the first through openings in one-to-one position, the second through openings 14 are located right above the corresponding first through openings, the edge of the first through hole is connected with a sample lifting pipe 6 in the vertical direction, a piston 5 is arranged in the sample lifting pipe 6, a lifting rod 9 is connected to the upper surface of the piston 5, the upper end of the lifting rod 9 penetrates through the second through hole 14 and is positioned above the shell 7, the outer surface of the lifting rod 9 is in contact with the inner side of the second through hole 14, a third through hole is formed in the side face of the shell 7, and a medicine outlet cylinder 12 is detachably connected to the third through hole.

In this embodiment, the height of the piston 5 is required to be smaller than the height of the housing 7, and when the lifting rod 9 pulls out the piston 5, the upper surface of the piston 5 contacts the upper wall of the housing 7, and a certain amount of space needs to flow out of the housing 7, so that the medicines are mixed.

In use, each sample extracting tube 6 is used for extracting a proper amount of medicine, one sample extracting tube 6 can extract one medicine, in the extracting process, the lower end of each sample extracting tube 6 faces the medicine, the piston 5 is pulled upwards by using the pull rod 9, so that the air pressure in the sample extracting tube 6 is changed by the piston 5, the medicine is extracted into the sample extracting tubes 6, when each sample extracting tube 6 extracts the proper medicine, the shell 7 is turned over, the sample extracting tubes 6 are upward, at the moment, the end of the piston 5 is reached when the piston 5 is pulled out by using the pull rod 9, at the moment, the upper surface of the piston 5 is in contact with the upper wall of the shell 7, the piston 5 is positioned at the second through opening 14, at the moment, all the medicines in each sample extracting tube 6 are positioned in the shell 7, at the moment, the medicines in the shell 7 are uniformly mixed by shaking, and after shaking, the mixed medicines are poured into the medicine discharging barrel 12, since the drug outlet cartridge 12 is detachably connected to the housing 7, the mixed drug can be taken out of the drug outlet cartridge 12.

Example 2

The present embodiment is based on example 1 and optimizes the implementation scheme in example 1, so that the present embodiment is more stable and better in performance during the operation process, but the present embodiment is not limited to the implementation manner described in the present embodiment.

Specifically, as shown in fig. 1 to 4, in this embodiment, a long-strip-shaped longitudinal groove 4 is formed in a surface of the lifting rod 9 facing the outer side of the housing 7, a longitudinal rack 13 is fixed on a groove wall of one side of the groove 4, the rack 13 is engaged with the gear 8, the gear 8 is fixedly connected with the rotating block 2 through the rotating rod 1 in the horizontal direction, and the rotating rod 1 is rotatably connected to the housing 7.

When carrying out carrying to the lifting rod 9, just need not manual upper end of holding lifting rod 9 to carry out carrying to lifting rod 9, but use rotatory piece 2 to rotate, in rotatory piece 2 pivoted, rotatory piece 2 drives dwang 1 and rotates, thereby it rotates to drive gear 8, thereby make rack 13 reciprocate for gear 8, thereby make lifting rod 9 reciprocate, when using rotatory piece 2 to adjust lifting rod 9's height, carry out the extraction of medicine for direct manual pulling lifting rod 9, make the extraction more accurate of medicine, this more be applicable to when extracting the medicine ration, and when converging medicine casing 7, can direct manual will carry out lifting rod 9 and all pull up.

Simultaneously, in this embodiment, be fixed with fixed block 3 on the casing 7, seted up horizontal through-hole on the fixed block 3, the middle part of dwang 1 is located the inside of through-hole, the pole body of dwang 1 pass through the bearing with the internal surface connection of through-hole.

Fixed block 3 can make the position height of dwang 1 by effectual fixed, simultaneously, the bearing that sets up inside fixed block 3 can make dwang 1 pivoted more smooth, the damping bearing that the bearing used for when rotatory dwang 1, rotatory power reaches certain degree and could be with dwang 1 pivoted, like this when rotating dwang 1, lifting rod 9 moves, when not rotating dwang 1, lifting rod 9 does not move.

Meanwhile, in the present embodiment, the sum of the dimension of the gear 8 in the horizontal direction and the dimension of the rack 13 in the horizontal direction is equal to the dimension of the groove 4 in the horizontal direction. This makes it possible to fill the grooves with the gear 8 and the rack 13 in the horizontal direction, so that when rotating, no trouble is likely to occur.

Example 3

Specifically, as shown in fig. 1 and 5, in the present embodiment, a pulling plate 10 is fixed to the top of the lifting rod 9. The pulling plate 10 can enable a person to lift the pulling plate 10, which is equivalent to lifting the lifting rod 9, and compared with the manual lifting of the lifting rod 9, the lifting effect of the pulling plate 10 can make the lifting easier.

Meanwhile, in this embodiment, a lifting column 15 is arranged above the housing 7, a side surface of a lower end of the lifting column 15 is connected with a circular ring 17 through a connecting rod 16, the circular ring 17 is equal to the lifting rod 9 in number and is in one-to-one correspondence with the lifting rod 9 in position, the circular ring 17 is sleeved on the lifting rod 9 and is located below the pulling plate 10, the overall diameter of the circular ring 17 is smaller than that of the pulling plate 10, and the overall diameter of the circular ring 17 is larger than that of the lifting rod 9.

After each sample lifting tube 6 extracts the medicine, all the lifting rods 9 should be lifted upwards, so that the piston 5 is located at the second opening 14, at this time, all the medicine in each sample lifting tube 6 is located in the shell 7, when the medicine is lifted, the lifting rods 15 are pulled due to the lifting rods 15, so that the connecting rods 16 and the circular rings 17 move, and since the outline diameter of the circular rings 17 is smaller than the outline diameter of the pulling plate 10 and larger than the outline diameter of the lifting rods 9, the movement of the circular rings 17 causes the pulling plate 10 to move therewith, so that the lifting rods 9 move, and all the lifting rods 9 perform the same movement.

In this embodiment, the sampling tube 6 is a transparent tube and the outer surface of the sampling tube 6 is provided with longitudinal scales. Therefore, the quantity of the medicines in the sampling tube 6 can be clearly known, so that the medicines in the sampling tube 6 can be extracted more accurately.

The above disclosure is only for a few specific embodiments of the present invention, however, the present invention is not limited to the embodiments, and any changes that can be considered by those skilled in the art shall fall within the protection scope of the present invention.
