Unlike available atomizing feeder, the atomizing pipe 9 has oscillating spring 8 around the outer periphery, and the oscillating spring 8 has two ends contacting the lower end of the medicine bottle 3 and the upper edge of the cylinder 1. In the initial state shown in fig. 1 and 8, the atomizing tube 9 is pushed away from the inflection point position of the communication hole 7 by the oscillating spring 8. In addition, the invention is provided with a drug delivery mechanism for pushing down the drug bottle 3 to deliver drug and a shaking mechanism which can be matched with the shaking spring 8 to forcedly shake the drug bottle 3 to homogenize the drug liquid in the drug bottle 3, and the shaking mechanism is linked with the drug delivery mechanism, so that the drug delivery mechanism is in a locking state before the shaking mechanism acts, and the situation of insufficient drug intake caused by direct drug delivery of patients, especially children patients, under the condition of not shaking the drug is avoided.
The following describes the technical scheme of the present invention in detail through two examples:
example 1
As shown in fig. 1, the upper end of the cylinder 1 in this embodiment is closed, and a first actuating rod 14 is inserted into the closed end of the upper portion of the cylinder 1. The upper end of the first actuating rod 14 extends out of the cylinder 1 and is rotationally connected with a first pressing handle 16, so that an operator can drive the first actuating rod 14 to move downwards through the first pressing handle 16, a supporting spring 15 is further sleeved between the first actuating rod 14 and the closed end of the upper part of the cylinder 1, the supporting spring 15 is used for compressing and generating elastic potential energy after the operator presses down the first pressing handle 16, and the operator can drive the first actuating rod 14 to move upwards to an initial state through the elastic potential energy after releasing hands. The cross section of the rod body of the first actuating rod 14 is circular, and the first actuating rod 14 and the closed end of the upper part of the cylinder body 1 are flexibly in sliding and flexible running fit. The lower part of the first actuating rod 14 extends into the inner cavity of the cylinder body 1 and is used for acting on the oscillating mechanism and the shaking-up mechanism in sequence, so that the medicine is administrated after the medicine bottle 3 oscillates and shakes up.
As shown in fig. 1 and 2, the oscillating mechanism in this embodiment includes a first table 12, a first pressing block 2, a first guide post 11, and a first guide holder 19. The first bearing platform 12 is fixed at the middle part of the medicine bottle 3 in the height direction, and the first guide seat 19 is fixed on the inner wall of the medicine cavity 4 and faces one side of the first bearing platform 12; the first pressure piece 2 and the first guide post 11 are both fixed to the first actuating lever 14. The first pressing block 2 is used for being matched with the first bearing platform 12, and the medicine bottle 3 is synchronously moved downwards by pressing the first bearing platform 12 and compresses the oscillating spring 8. After the oscillation spring 8 accumulates enough elastic potential energy, the first pressing block 2 is separated from the first bearing platform 12 through the rotation of the first actuating rod 14, so that the medicine bottle 3 is subjected to violent oscillation under the action of the elastic potential energy of the oscillation spring 8, and the purpose of shaking the medicine liquid in the medicine bottle 3 is achieved.
The first guide post 11 is configured to cooperate with the first guide seat 19 to implement automatic rotation of the first actuating lever 14 during the operation of pressing and pushing by an operator, specifically:
as shown in fig. 3, the back side of the first guide seat 19 facing is used for fixing with the inner wall of the medicine cavity 4, the front side of the first guide groove 10 is provided with an arc surface 20, and the arc surface 20 is concentrically distributed with the first actuating rod 14 as shown in fig. 2. As shown in fig. 1 and 3, a first guide groove 10 for inserting and sliding fit of the first guide post 11 is provided on the circular arc surface 20, and the first guide post 11 is always inserted and sliding fit with the first guide groove 10 due to the arrangement of the circular arc surface 20, and the first actuating lever 14 can be controlled to rotate through the fit relationship between the first guide groove 10 and the first guide post 11. The first guide groove 10 has an upper vertical section, a lower vertical section, and an arc section smoothly connecting the upper and lower vertical sections, which are staggered in the lateral direction. The first guide groove 10 shown in fig. 1 is actually a projection of the first guide groove 10 on a longitudinal section, and is only used to show a relative positional relationship between the first guide groove 10 and the first guide post 11 in height. In the process of pushing the first actuating rod 14 downwards through the first pressing handle 16, when the first guide post 11 is matched with the upper vertical section, the first pressing block 2 is located right above the first bearing platform 12, and can push the first bearing platform 12 and the medicine bottle 3 to downwards move along with the downwards movement of the first actuating rod 14 so as to compress the oscillating spring 8. When the first actuating rod 14 continuously moves downwards to enable the first guide post 11 to enter the arc section, the first actuating rod 14 rotates due to sliding connection cooperation of the first guide post 11 and the arc section, so that the first pressing block 2 synchronously rotates and is separated from the first bearing platform 12, until the first guide post 11 continuously moves downwards to enable the first pressing block 2 to slide into the lower vertical section along with the continuous movement of the first actuating rod 14 and then completely rotate away from the first bearing platform 12, and the medicine bottle 3 starts to oscillate and shake the medicine liquid under the action of the oscillating spring. The first pressing handle 16 is rotatably connected with the upper end of the first actuating rod 14, so that the operator does not rotate the first pressing handle 16 during the process of pressing the first pressing handle 16 to drive the first actuating rod 14 to move downwards, thereby avoiding slipping with the hand of the operator.
As shown in fig. 1 and 2, the drug delivery mechanism in this embodiment is a second pressing block 13 fixed on a first actuating rod 14. The fixed position of the second pressing block 13 on the first actuating rod 14 is higher than the first pressing block 2, and the distribution angle of the second pressing block 13 on the first actuating rod 14 is staggered with the first pressing block 2, so that the second pressing block 13 is staggered on the first bearing platform 12 in the initial state shown in fig. 2, the first guide post 11 slides into the lower vertical section through the arc section in the first guide groove 10, the second pressing block 13 is positioned right above the first bearing platform 12 after the first actuating rod 14 rotates, and an operator continuously presses the first pressing handle 16 to press the medicine bottle 3 through the cooperation of the second pressing block 13 and the first bearing platform 12 until the atomization tube 9 is in contact with the inflection point of the communication hole 7 for atomization medicine feeding.
The specific implementation process of this embodiment is as follows:
fig. 1 and 2 show an initial state of the present embodiment, in which the first guide posts 11 are inserted into the upper vertical section of the first guide groove 10, the first pressing blocks 2 are located right above the first bearing platform 12, and the second pressing blocks 13 are distributed on the first bearing platform 12 in a staggered manner.
When an operator performs emergency drug administration, the operator directly presses the first pressing handle 16 to drive the first actuating rod 14 to move downwards, the first guide column 11 moves downwards along the upper vertical section, and meanwhile, the drug bottle 3 moves downwards under the cooperation of the first pressing block 2 and the first bearing platform 12 and compresses the oscillating spring 8. After the first guide post 11 slides into the arc section, the first actuating rod 14 moves downwards and rotates, and after the first guide post 11 slides into the lower vertical section, the first pressing block 2 shown in fig. 6 is completely separated from the first bearing platform 12. The medicine bottle 3 is quickly lifted to the state shown in fig. 5 under the driving action of the oscillating spring 8, and then continuously lifted to enable the oscillating spring 8 to generate stretching deformation, and then the medicine bottle 3 is pulled to move downwards to oscillating and shaking the medicine in the medicine bottle 3 in a reciprocating manner.
Meanwhile, as shown in fig. 6, after the first guide post 11 slides into the lower vertical section to rotate the first actuating rod 14, the second pressing block 13 is also located right above the first bearing platform 12. The operator continuously presses down the first pressing handle 16, namely presses down the medicine bottle 3 through the second pressing block 13, and the medicine is administrated to the inflection point position of the atomization tube 9, where the inflection point of the communication hole 7 is propped against.
Therefore, through the above technical scheme of this embodiment, make the patient in through pushing down first pressure handle 16 in the use of medicine, must at first trigger shake even mechanism shake even liquid medicine, then administer, avoided the condition that the medicine is administered under the condition of shaking even state promptly that leads to because of the panic that the condition caused.
In this embodiment, in order to pull out and reset the first actuating rod 14 through the supporting spring 15 or manpower after the end of the drug administration, the first bearing platform 12 is prevented from blocking the first pressing block 2, and the first pressing block 2 on the first actuating rod 14 is arranged in a unidirectional limiting manner. As shown in fig. 4, a rectangular groove 23 is formed in the first actuating rod 14 and distributed in a self-longitudinal direction, the first pressing block 2 is distributed in a radial direction of the first actuating rod 14, the right end of the first pressing block 2 is connected with the bottom of the right upper side of the rectangular groove 23 in a rotating fit manner through a rotating shaft 21, and a reset spring 31 is sleeved on the rotating shaft 21. The return spring 31 in fig. 4 is in a deformed and energy-storing state and provides a force pushing the first press block 2 to rotate so as to keep it protruding out of the rectangular groove 23. The upper side groove wall of the rectangular groove 23 forms a positioning surface 44, and the positioning surface 44 is used for being matched with the upper edge of the right end of the first pressing block 2, so that the first pressing block 2 is prevented from transitionally rotating under the action of the torsion spring 22, and is kept in the state shown in fig. 4. At this time, the first carrier 12 is pushed down by the lower edge of the first presser 2 by the downward movement of the first actuator lever 14 to move the vial 3 downward. After the end of the drug administration, the upper edge of the first pressing block 2 contacts with the lower edge of the first bearing platform 12 in the process that the first actuating rod 14 is lifted up under the driving of the supporting spring 15 or manpower, and the lower edge of the first bearing platform 12 toggles the first pressing block 2 to rotate into the accommodating cavity 45 formed by the rectangular groove 23 by taking the rotating shaft 21 as the center. After the first pressing block 2 rises to be separated from the first bearing platform 12, the first pressing block can extend out of the rectangular groove 23 to an initial state again under the elastic force of the torsion spring 22.
Example 2
As shown in fig. 8 and 9, the top of the cylinder 1 of the present embodiment is also closed and slidably provided with a second actuating lever 25 and a third actuating lever 39. The upper ends of the second actuating rod 25 and the third actuating rod 39 respectively extend out of the cylinder body 1 and are respectively and rotatably connected with a second pressing handle 24 and a third pressing handle 40, so that an operator can respectively drive the second actuating rod 25 to move downwards through the second pressing handle 24 and drive the third actuating rod 39 to move downwards through the third pressing handle 40. The rod body cross sections of the second actuating rod 25 and the third actuating rod 39 are circular, wherein the second actuating rod 25 is flexibly and slidingly matched with the closed end of the upper part of the cylinder body 1 in a flexible and rotating way, and the lower part of the second actuating rod 25 stretches into the inner cavity of the cylinder body 1 and acts on the oscillating mechanism; the third actuating rod 39 is only in flexible sliding fit with the closed end of the upper part of the barrel 1 to limit rotation, and the lower part of the third actuating rod 39 extends into the inner cavity of the barrel 1 and acts on the drug delivery mechanism.
Similar to the shaking mechanism in embodiment 1, the shaking mechanism in this embodiment includes a second support table 27 fixed on the liquid medicine bottle, a second guide seat 41 fixed on the inner wall of the medicine cavity 4, and a third pressing block 26 and a second guide post 28 fixed on the second actuating lever 25. The second table 27, the second guide holder 41, the third press block 26, and the second guide column 28 in this embodiment correspond to the first table 12, the first guide holder 19, the first press block 2, and the first guide column 11 in embodiment 1, respectively. The second guide seat 41 is provided with a second guide groove 29, and the second guide groove 29 has the same structure as the first guide groove 10 in embodiment 1, and comprises an upper vertical section, a lower vertical section and an arc section connecting the upper vertical section and the lower vertical section, which are distributed in parallel at intervals. When the second guide post 28 is inserted into the upper vertical section, the third pressing block 26 is positioned right above the second bearing platform 27, and the second guide post 28 slides into the lower vertical section from the upper vertical section through the arc section, so that the third pressing block 26 is staggered with the second bearing platform 27. In the present embodiment, similarly to embodiment 1, in the process of driving the second actuating lever 25 to move downward by pressing the second pressing handle 24, the third pressing block 26 is used to press the second bearing platform 27 and the medicine bottle 3 to move downward and compress the oscillation spring 8 until the second actuating lever 25 rotates by the cooperation of the second guide post 28 and the second guide groove 29, and then the third pressing block 26 rotates away from the second bearing platform 27, so that the medicine bottle 3 oscillates and shakes the medicine liquid under the action of the oscillation spring 8.
Unlike the solution of embodiment 1 in which the administration is performed by continuously moving the first actuating lever 14 downward, the shaking of the liquid medicine is achieved only by the second actuating lever 25 in this embodiment, and the administration is achieved by the third actuating lever 39. Thus, the shaking and the drug administration process are forced to be carried out at time intervals, so that when an operator presses the second actuating rod 25 to separate the drug bottle 3 from the pressing of the second pressing block 13 and presses the third actuating rod 39 to administer drug, the time for switching the pressing part by the operator is provided for the drug bottle 3 to sufficiently oscillate, and the shaking effect of the drug is ensured.
The drug delivery mechanism in this embodiment includes a third cap 37 fixed to the drug vial 3 and a fourth presser piece 38 fixed to a third actuator rod 39, the fourth presser piece 38 being located directly above the third cap 37. After the medicines in the medicine bottle 3 are uniformly shaken by oscillation, an operator presses the third actuating rod 39 to move downwards through the third pressing handle 40, the fourth pressing block 38 pushes the third bearing platform 37 and the medicine bottle 3 to move downwards until the atomization tube 9 is inserted to the inflection point of the communication hole 7, and the direction pressure provided by the inflection point drives the atomization tube 9 to spray atomized medicines. In order to avoid the rotation of the third actuating rod 39 during the downward movement, as shown in fig. 9 and 10, a third guiding seat 42 for limiting sliding fit of the third actuating rod 39 is further provided in the medicine cavity 4, third guiding grooves 35 distributed vertically are provided on the third guiding seat 42, and third guiding columns 36 inserted in the third guiding grooves 35 and sliding fit with the third guiding grooves 35 are correspondingly provided on the third actuating rod 39. The third actuating rod 39 is prevented from rotating by the cooperation of the third guide post 36 and the third guide holder 42, so that the relative positions of the fourth pressing block 38 and the third bearing platform 37 are maintained.
In order to ensure the sliding stability of the medicine bottle 3, as shown in fig. 9, a wire rail 18 is arranged on the inner wall of the medicine cavity 4, a support 17 is fixedly arranged on the back side of the medicine bottle 3, and a chute matched with the wire rail 18 in a clamping manner is arranged on the support 17, so that the medicine bottle 3 is made stable on the front side and the rear side in the sliding process.
In example 1, the shaking-up and administration operations were sequentially performed by pressing down the first actuator lever 14, i.e., there was no case where administration was directly performed without shaking-up. In order to avoid that the operator directly presses the third actuating lever 39 to perform the drug administration before pressing the second actuating lever 25 to perform the shaking operation in the present embodiment, a locking member for locking the third actuating lever 39 for the drug administration by pressing the third actuating lever 39 is further provided in the drug cavity 4, and the locking member is linked with the second actuating lever 25 and unlocks the third actuating lever 39 after the shaking mechanism acts, so that the operator is still forced to perform the shaking and drug administration operations sequentially.
As shown in fig. 8, the locking member is a sliding limit top block 30. The sliding limiting top block 30 is annular, a linear rail 18 (not shown in the figure) for the sliding of the sliding limiting top block along the horizontal direction is arranged on the upper edge of the partition, a return spring 31 is arranged between the left side of the sliding limiting top block 30 and the inner wall of the corresponding medicine cavity 4, and the return spring 31 enables the sliding limiting top block 30 to be in an initial state shown in fig. 8 in a natural extension state. In the initial state, the atomizing pipe 9 passes through the central inner hole of the sliding limiting top block 30 and is inserted into the communication hole 7, and the aperture of the sliding limiting top block 30 is larger, so that interference to the atomizing pipe 9 is avoided when the inner side of the ring body of the sliding limiting top block 30 slides along the line rail 18 under the action of external force. The upper edge of the right side of the sliding limiting top block 30 forms a limiting surface 34, and the lower end of the third actuating rod 39 abuts against the limiting surface 34 to form a locking effect on the third actuating rod 39, so that the third actuating rod 39 cannot move downwards further for drug delivery. The upper corner of the left side of the sliding limiting top block 30 forms a matching angle 33, the lower end of the second actuating rod 25 is provided with a wedge surface 43, and the sharp corner of the wedge surface 43 is opposite to the matching angle 33, so that after the wedge surface 43 is inserted into the inner hole of the sliding limiting top block 30, the sliding limiting top block 30 is pushed to move left against the thrust of the return spring 31, and the limiting surface 34 is staggered from the third actuating rod 39, thereby achieving the effect of unlocking the third actuating rod 39.
The specific implementation process of this embodiment is as follows:
fig. 8 and 9 show the initial state of the present embodiment, in which the second guide post 28 is inserted into the upper vertical section of the second guide groove 29, and the third pressing block 26 is located right above the second bearing platform 27.
When an operator performs emergency medication administration, the operator directly presses the second pressing handle 24 to drive the second actuating rod 25 to move downwards, the second guide column 28 moves downwards along the upper vertical section, and simultaneously the medicine bottle 3 moves downwards under the cooperation of the third pressing block 26 and the second bearing platform 27 and compresses the oscillating spring 8. After the second guide post 28 slides into the arc section, the second actuating rod 25 moves downwards and rotates, and after the second guide post 28 slides into the lower vertical section, the third pressing block 26 shown in fig. 12 is completely separated from the second bearing platform 27. The medicine bottle 3 is quickly lifted to the state shown in fig. 11 under the driving action of the oscillating spring 8, and then continuously lifted to enable the oscillating spring 8 to generate stretching deformation, and then the medicine bottle 3 is pulled to move downwards to oscillating and shaking the medicine in the medicine bottle 3 in a reciprocating manner. While the wedge surface 43 at the lower end of the second actuating lever 25 also rotates from the back side to just above the point mating angle 33 as shown in fig. 11.
While the medicine bottle 3 oscillates and shakes evenly, the operator continues to press the second actuating lever 25, and the wedge surface 43 cooperates with the cooperation angle 33 to drive the sliding limiting top block 30 to move horizontally leftwards until the limiting surface 34 is staggered by the third actuating lever 39 as shown in fig. 13. At this time, the operator can drive the third actuating rod 39 to move downwards through the third pressing handle 40, and continuously press the medicine bottle 3 by the fourth pressing block 38 and the third bearing platform 37 until the lower end of the third actuating rod 39 is inserted into the blind hole 32 formed on the partition to perform the abdicating function as shown in fig. 14, and the atomized medicine is sprayed out from the atomized pipe 9 for administration.
