Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a disinfection device for diluting medicinal powder in ampoules. Background Art

[0002] Currently, during the process of diluting medicine, it is usually necessary to transfer the powdered medicine in the ampoule to an infusion bottle so that the medicine can be intravenously infused into the human body. Specifically, a syringe first sucks in a part of the liquid medicine, then the needle of the syringe is inserted into the stopper of the ampoule, so that the liquid medicine in the syringe is injected into the ampoule through the needle. After the powdered medicine in the ampoule is dissolved in the liquid medicine, the syringe is used to draw out the liquid medicine in the ampoule, and then the drawn liquid medicine is transferred to the infusion bottle.

[0003] However, the inventor has found that there are still deficiencies in the current medicine dilution operation, specifically:

[0004] During medicine dilution, it is usually necessary to disinfect the stopper of the ampoule to prevent contaminants on the stopper of the ampoule from entering the ampoule when the needle pierces the stopper, thereby contaminating the medicine in the ampoule. Currently, when disinfecting the stopper of the ampoule, a cotton swab is usually used for disinfection. The disinfectant is dropped onto the cotton swab, and then the cotton swab is used to wipe the stopper of the ampoule to reduce the contaminants on the stopper of the ampoule. However, the manual disinfection method is time-consuming and laborious, and it is difficult to ensure the disinfection quality of each ampoule; moreover, before the needle pierces the stopper, the outer wall of the needle will also be contaminated by the external environment. During the process of the needle piercing the stopper, there is a situation where the contaminants on the outer wall of the needle enter the ampoule. Thus, the current disinfection method is difficult to disinfect both the stopper of the ampoule and the needle of the syringe at the same time, increasing the risk of contamination of the medicine in the ampoule during the medicine dilution process.

[0005] Therefore, based on the above deficiencies, there is an urgent need to design a disinfection device for diluting medicinal powder in ampoules to achieve the purpose of disinfecting both the stopper of the ampoule and the needle at the same time and reducing the risk of contamination of the medicine in the ampoule during the medicine dilution process. Summary of the Invention

[0006] The purpose of the present invention is to provide a disinfection device for diluting medicinal powder in ampoules to achieve the purpose of disinfecting both the stopper of the ampoule and the needle at the same time and reducing the risk of contamination of the medicine in the ampoule during the medicine dilution process, aiming at the above deficiencies that occur during the current medicine dilution operation.

[0007] To achieve the above technical purpose, the technical solution adopted by the present invention is:

[0008] A disinfection device for matching medicine in a vial, comprising a placement seat, a disinfection spray head and a driving assembly; the placement seat is provided with a placement cavity, a supporting member and a first spring are arranged in the placement cavity, one end of the first spring is connected to the supporting member, and the other end is connected to the bottom of the placement cavity, and the supporting member is used for supporting the bottom of the vial; the disinfection spray head is located obliquely above the placement seat, and the disinfection spray head is provided with a first spray port and a second spray port, the first spray port is used for spraying an air flow carrying a disinfectant, and the second spray port is used for spraying an air flow not carrying a disinfectant; the driving assembly is used for driving the disinfection spray head to rotate synchronously when moving towards the placement seat, so that the included angle α formed between the spray port of the disinfection spray head and the vertical direction gradually increases;

[0009] During the process that the extraction device gradually pierces into the vial, the driving assembly drives the disinfection spray head to rotate, so that the included angle α between the air flow sprayed by the disinfection spray head and the vertical direction gradually increases, so that the action area of the air flow gradually changes from the bottle stopper to the needle tip, and any disinfected area on the bottle stopper or the needle tip of the vial first contacts the air flow sprayed from the first spray port, and then contacts the air flow sprayed from the second spray port;

[0010] During the whole process that the end of the needle tip pierces into the bottle stopper, the air flow sprayed from the first spray port acts on the needle tip, the air flow sprayed from the second spray port acts on the bottle stopper, and the air flow sprayed from the second spray port provides a driving force to make the vial and the supporting member move towards the bottom direction of the placement cavity together, so that the first spring is compressed;

[0011] After the needle tip pierces through the bottle stopper, the air flows sprayed from the first spray port and the second spray port act on the needle tip, and the bottle stopper of the vial makes the first spring gradually recover its deformation under the action of no air flow pushing force, so that the supporting member and the vial move away from the bottom of the placement cavity.

[0012] As a preferred technical solution of the present application, the driving assembly includes a resisting member, a rack and a gear, one side of the disinfection spray head is rotatably connected to the resisting member, the other side is fixedly provided with the gear, the rack is vertically fixed on the placement seat, the gear meshes with the rack, and the resisting member is used for cooperating with the extraction device; during the process that the needle tip on the extraction device pierces into the vial, when the extraction device drives the resisting member and the disinfection spray head to move towards the placement seat synchronously, the gear rotates relative to the rack to drive the disinfection spray head to rotate, so as to realize an increase in the included angle α formed between the spray port of the disinfection spray head and the vertical direction.

[0013] As a preferred technical solution of the present application, the driving assembly further includes a spring support rod, one end of the spring support rod is arranged on the placement seat, and the other end is connected to the resisting member; during the process that the needle tip on the extraction device pierces into the vial, the extraction assembly can abut against the resisting member to drive the resisting member to move, and the spring support rod is gradually compressed.

[0014] As a preferred technical solution of the present application, the disinfection nozzle has an initial state. When the disinfection nozzle is in the initial state, the first nozzle sprays out an air flow carrying the disinfectant solution, so that the air flow acts on the bottle stopper of the vial placed in the placement seat.

[0015] As a preferred technical solution of the present application, the placement cavity includes a first section of the placement cavity. The first section of the placement cavity is located in the lower section of the placement cavity. The inner dimension of the first section of the placement cavity is adapted to the outer dimension of the support member. When the support member is in the first section of the placement cavity, the first section of the placement cavity restricts the movement direction of the support member, so that the movement direction of the support member is the same as the direction of the central axis of the first section of the placement cavity.

[0016] During the whole process of the end of the needle piercing into the bottle stopper, the support member is in the first section of the placement cavity.

[0017] As a preferred technical solution of the present application, a limiting groove is formed on the support member. The inner diameter of the limiting groove is adapted to the outer diameter of the vial, and the limiting groove fixes the bottom of the vial.

[0018] As a preferred technical solution of the present application, the placement cavity further includes a second section of the placement cavity. The second section of the placement cavity is located in the upper section of the placement cavity. After the needle pierces through the bottle stopper, the bottle stopper of the vial makes the first spring gradually recover its deformation under the action of no air flow pushing force, so that the support member and the vial move in a direction away from the bottom of the placement cavity, so that the support member moves into the second section of the placement cavity.

[0019] As a preferred technical solution of the present application, the second section of the placement cavity is in an open shape with a smaller lower part and a larger upper part. The central axis of the first spring and the central axis of the support member are not collinear. During the process of the needle piercing through the bottle stopper and then piercing towards the bottom of the vial, the support member is in the second section of the placement cavity, and the first spring can be bent, so that the vial and the support member are inclined, and when the end of the needle touches the bottom of the vial, the end of the needle is located at the lowest point of the bottom of the vial.

[0020] As a preferred technical solution of the present application, the transition between the first section of the placement cavity and the second section of the placement cavity is smooth.

[0021] As a preferred technical solution of the present application, a rubber pad is arranged on the side surface of the limiting groove. The rubber pad has elasticity, and the rubber pad is used to increase the stability when the vial cooperates with the limiting groove.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] 1. In the solution of the present application, by providing a disinfection nozzle, when the disinfection nozzle is in the initial state, the disinfection nozzle sprays an air stream carrying a disinfectant solution, and the air stream acts on the stopper of the vial placed in the placement seat, thereby disinfecting the stopper of the vial. Before the needle on the extraction device pierces the stopper of the vial, as the needle gradually approaches the vial, the driving assembly drives the disinfection nozzle to rotate, so that the included angle α gradually increases, and the area where the air stream acts gradually changes from the stopper to the side wall of the needle, thereby disinfecting the stopper and the needle at the same time. And before the needle pierces the stopper of the vial, the air stream carrying the disinfectant solution acts on the needle and does not act on the stopper, so that during the process of the needle piercing the stopper of the vial, it is possible to avoid the air stream carrying the disinfectant solution from impacting the piercing point on the stopper, and further avoid the air stream carrying the disinfectant solution from entering the vial from the piercing point, thereby avoiding the disinfectant solution from contaminating the liquid medicine in the vial. At the same time, during the process of the needle gradually piercing into the vial, the driving assembly continuously drives the disinfection nozzle to rotate, so that the included angle α continuously increases, thereby increasing the area of the needle disinfected by the air stream, and further improving the disinfection effect of the needle. Therefore, the disinfection device of the present application can disinfect the stopper and the needle of the vial at the same time, and can reduce the risk of contamination of the medicine in the vial during the medicine preparation process;

[0024] 2. Further, by providing a first nozzle and a second nozzle, during the process of the extraction device stabbing the vial and the air stream disinfecting the stopper or the needle of the vial, any disinfected area on the stopper or the needle of the vial first contacts the air stream ejected from the first nozzle, and then contacts the air stream ejected from the second nozzle. In this way, the air stream not carrying the disinfectant solution ejected from the second nozzle can impact the stopper or the needle disinfected by the disinfectant solution, so as to reduce the residue of the disinfectant solution on the stopper or the needle, improve the volatilization speed of the residual disinfectant solution, and thus further improve the disinfection effect of disinfecting the bottle cap or the needle;

[0025] 3. Further, by providing the second stage of the placement cavity, after the needle pierces the vial stopper, the airflows ejected from the first nozzle and the second nozzle act on the needle and do not act on the vial stopper. Without the acting force of the airflow to push it, the first spring gradually resumes its deformation, and the elastic force provided by the first spring can overcome the frictional force between the side wall of the needle and the vial stopper, causing the support member and the vial to move away from the bottom of the placement cavity. In this way, the time for the needle to penetrate from the vial stopper to the bottom of the vial can be saved, and the movement of the vial and the medicament inside the vial can be intensified, which can further improve the dissolution efficiency between the powdery medicament and the liquid medicine inside the vial. At the same time, after the first spring gradually resumes its deformation, the force required to increase the deformation amount of the first spring can be reduced, so that after the needle penetrates the bottom of the vial, the impact risk between the end of the needle and the bottom of the vial can be further reduced, and the needle can be further prevented from being damaged;

[0026] 4. Further, make the second stage of the placement cavity be open-shaped, and make the central axis of the first spring and the central axis of the support member be in a non-collinear state. During the process of the needle piercing the vial stopper and then stabbing towards the bottom of the vial, the support member and the vial can be located inside the second stage of the placement cavity. The piercing point on the vial for the needle to penetrate is located on the central axis of the vial, and the central axis of the vial is collinear with the central axis of the support member. In this way, the piercing point is not in the direction of the central axis of the first spring. On the basis of the side wall of the needle applying a force to the vial stopper, the first spring is bent. The open-shaped second stage of the placement cavity provides a moving space, causing the vial and the support member to tilt, so that when the end of the needle touches the bottom of the vial, the end of the needle is at the lowest point of the bottom of the vial. Thus, when the extraction device sucks the liquid medicine in the vial, the residue of the medicament in the vial can be further reduced, and during the tilting process of the vial, the dissolution of the powdery medicament in the vial can be further intensified.

[0038] Embodiment 1: A disinfection device for dispensing medicine into vials provided in this embodiment is shown in Figures 1 - 4 Figure 1, and includes a placement base 1, a disinfection spray head 2, and a driving assembly 3. The placement base 1 is used for placing vials. The disinfection spray head 2 is located obliquely above the placement base 1. A first nozzle 8 is provided on the disinfection spray head 2. The disinfection spray head 2 has an initial state. When the disinfection spray head 2 is in the initial state, the first nozzle 8 of the disinfection spray head 2 faces the central area of the placement base 1. The driving assembly 3 is used to drive the disinfection spray head 2 to rotate, so that the angle α formed between the first nozzle 8 of the disinfection spray head 2 and the vertical direction gradually increases. In the initial state, the disinfection spray head 2 sprays out an air flow carrying disinfectant through the first nozzle 8, and this air flow acts on the stopper of the vial placed on the placement base 1 to disinfect the stopper. Before the needle on the extraction device pierces the stopper of the vial, as the needle gradually approaches the vial, the driving assembly 3 drives the disinfection spray head 2 to rotate, so that the angle α formed between the first nozzle 8 of the disinfection spray head 2 and the vertical direction gradually increases, so that the area where the air flow acts gradually changes from the stopper to the side wall of the needle. During the process of the needle gradually piercing into the vial, the driving assembly 3 continuously drives the disinfection spray head 2 to rotate, and the angle α continuously increases.

[0039] In this application, the disinfection spray head 2 is provided such that when the disinfection spray head 2 is in the initial state, the disinfection spray head 2 sprays out an air flow carrying disinfectant, and this air flow acts on the stopper of the vial placed on the placement base 1 to disinfect the stopper of the vial. Before the needle on the extraction device pierces the stopper of the vial, as the needle gradually approaches the vial, the driving assembly 3 drives the disinfection spray head 2 to rotate, so that the angle α formed between the first nozzle 8 of the disinfection spray head 2 and the vertical direction gradually increases, so that the area where the air flow acts gradually changes from the stopper to the side wall of the needle above the stopper, thereby disinfecting the stopper and the needle at the same time. And before the needle pierces the stopper of the vial, the air flow carrying disinfectant acts on the needle and does not act on the stopper, so that during the process of the needle piercing into the stopper of the vial, it is possible to avoid the impact of the air flow carrying disinfectant on the piercing point on the stopper, and further avoid the air flow carrying disinfectant entering the vial from this piercing point, avoiding the contamination of the liquid medicine in the vial by the disinfectant. At the same time, during the process of the needle gradually piercing into the vial, the driving assembly 3 continuously drives the disinfection spray head 2 to rotate, so that the angle α continuously increases, thereby increasing the area of the needle disinfected by the air flow, further improving the disinfection effect of the needle. Therefore, the disinfection device of this application can disinfect the stopper and the needle of the vial at the same time, and can reduce the risk of contamination of the medicine in the vial during the medicine dispensing process.

[0040] As a preferred embodiment, on the basis of the above-described manner, the driving assembly 3 includes a resisting member 4, a rack 5, and a gear 6. One side of the disinfection nozzle 2 is rotatably disposed on the resisting member 4, and the gear 6 is fixedly disposed on the other side. The rack 5 is vertically fixed on the placing seat 1, and the gear 6 meshes with the rack 5. The resisting member 4 is used to cooperate with the extraction device. During the process that the needle on the extraction device stabs the vial, the extraction device cooperates with the resisting member 4, and the extraction device drives the resisting member 4 and the disinfection nozzle 2 to move synchronously in the direction close to the vial. During this process, the meshing part between the gear 6 and the rack 5 changes, and the gear 6 rotates relative to the rack 5 to drive the disinfection nozzle 2 to rotate, so that the included angle α gradually increases, thereby enabling the airflow ejected from the disinfection nozzle 2 to disinfect the stopper and the needle of the vial in sequence, improving the convenience of disinfection.

[0041] As a preferred embodiment, on the basis of the above-described manner, further, the driving assembly 3 further includes a spring support rod 7. One end of the spring support rod 7 is disposed on the placing seat 1, and the other end is connected to the resisting member 4. During the process that the needle on the extraction device stabs the vial, the extraction device can abut against the resisting member 4 to drive the resisting member 4 to move, and the spring support rod 7 is gradually compressed. After the liquid medicine in the vial is sucked into the extraction device, during the process of withdrawing the needle from the vial, the extraction device moves in the direction away from the placing seat 1. At this time, the spring support rod 7 gradually restores its deformation, so that the resisting member 4 also moves in the direction away from the placing seat 1. In this way, it is convenient to automatically reset the resisting member 4 and the disinfection nozzle 2.

[0042] Embodiment 2: On the basis of the technical solution of Embodiment 1, further, as shown in Figures 1 - 4 the disinfection nozzle 2 further includes a second nozzle 9. The second nozzle 9 is located behind the rotation direction of the first nozzle 8 when the disinfection nozzle 2 moves toward the placing seat 1. The second nozzle 9 is used to eject an airflow without carrying disinfectant. During the process that the extraction device stabs the vial and the airflow disinfects the stopper or the needle of the vial, any disinfected area on the stopper or the needle of the vial first contacts the airflow ejected from the first nozzle 8, and then contacts the airflow ejected from the second nozzle 9. In this way, the airflow without carrying disinfectant ejected from the second nozzle 9 can impact the stopper or the needle that has been disinfected by the disinfectant, so as to reduce the residue of the disinfectant on the stopper or the needle, improve the volatilization speed of the residual disinfectant, and thus further improve the disinfection effect of disinfecting the bottle cap or the needle.

[0043] As a preferred embodiment, on the basis of the above manner, further, a placement cavity 10 is provided on the placement base 1. A supporting member 11 and a first spring 12 are arranged in the placement cavity 10. One end of the first spring 12 is connected to the supporting member 11, and the other end is connected to the bottom of the placement cavity 10. The supporting member 11 is used to support the bottom of the vial. By providing the supporting member 11 and the first spring 12, the supporting member 11 supports the bottom of the vial. When the vial is placed on the supporting member 11, the first spring 12 can play a buffering role, and can reduce the impact on the bottom of the vial when the vial is placed on the supporting member 11, reducing the risk of the vial being broken.

[0044] As a preferred embodiment, on the basis of the above manner, further, the placement cavity 10 includes a first section of the placement cavity 13, and the first section of the placement cavity 13 is located in the lower section of the placement cavity 10. The inner size of the first section of the placement cavity 13 is adapted to the outer size of the supporting member 11. When the supporting member 11 is in the first section of the placement cavity 13, the first section of the placement cavity 13 restricts the movement direction of the supporting member 11, so that the movement direction of the supporting member 11 is the same as the central axis direction of the first section of the placement cavity 13. Further, a limiting groove 14 is formed on the supporting member 11, and the inner diameter of the limiting groove 14 is adapted to the outer diameter of the vial to fix the bottom of the vial. During the whole process that the end of the needle pierces into the vial stopper, the airflow ejected from the first nozzle 8 acts on the needle, and the airflow ejected from the second nozzle 9 acts on the vial stopper. The airflow ejected from the second nozzle 9 provides a driving force to make the vial and the supporting member 11 move together towards the bottom direction of the placement cavity 10, so that the first spring 12 is compressed and the supporting member 11 is in the first section of the placement cavity 13. After the supporting member 11 is limited by the first section of the placement cavity 13, the stability of the needle piercing the vial stopper can be improved. At the same time, the setting of the limiting groove 14 improves the stability of the relative position between the vial and the supporting member 11.

[0045] As a preferred embodiment, on the basis of the above method, further, the placement cavity 10 further includes a second-stage placement cavity 15. The second-stage placement cavity 15 is located in the upper section of the placement cavity 10. After the needle pierces the bottle stopper, the air flow ejected from the first nozzle 8 and the second nozzle 9 acts on the needle. The bottle stopper of the vial causes the first spring 12 to gradually recover its deformation without being pushed by the air flow. The elastic force provided by the first spring 12 can overcome the friction between the side wall of the needle and the bottle stopper, causing the support member 11 and the vial to move away from the bottom of the placement cavity 10, so that the support member 11 is located in the second-stage placement cavity 15. In this way, the time for the needle to pierce from the bottle stopper to the bottom of the vial can be saved, and the movement of the vial and the medicament in the vial can be intensified, which can further improve the dissolution efficiency between the powdery medicament and the liquid medicine in the vial. At the same time, after the first spring 12 gradually recovers its deformation, the force required to increase the deformation of the first spring 12 can be reduced, so that after the needle pierces the bottom of the vial, the impact risk between the end of the needle and the bottom of the vial can be further reduced, and the needle can be further prevented from being damaged.

[0046] Embodiment 3: On the basis of the technical solution of Embodiment 2, further, as shown in Figures 1 - 4 As shown, the second-stage placement cavity 15 is in an open shape, and the central axis of the first spring 12 and the central axis of the support member 11 are not collinear. During the process of the needle piercing the bottle stopper and then piercing the bottom of the vial, the support member 11 is located in the second-stage placement cavity 15, and the first spring 12 can bend, causing the vial and the support member 11 to tilt, and making the end of the needle located at the lowest point of the bottom of the vial when the end of the needle touches the bottom of the vial. The piercing point on the vial for the needle to pierce is located on the central axis of the vial, and the central axis of the vial is collinear with the central axis of the support member 11. In this way, the piercing point is not in the direction of the central axis of the first spring 12. On the basis of the side wall of the needle applying a force to the bottle stopper, the first spring 12 bends. Its open second-stage placement cavity 15 provides a moving space, causing the vial and the support member 11 to tilt, so that when the end of the needle touches the bottom of the vial, the end of the needle is located at the lowest point of the bottom of the vial. Thus, when the extraction device sucks the liquid medicine in the vial, the residue of the medicament in the vial can be further reduced, and during the tilting process of the vial, the dissolution of the powdery medicament in the vial can be further intensified; there is a moving space in the placement cavity 10 that can cause the first spring 12 to bend.

[0047] As a preferred embodiment, on the basis of the above method, further, a smooth transition is provided between one section 13 of the placement cavity and two sections 15 of the placement cavity. After the vial is placed on the support member 11, the airflow ejected by the disinfection nozzle 2 exerts a pushing effect on the stopper of the vial, and the pushing effect generated by the airflow can ensure that the support member 11 slides along the side walls of two sections 15 of the placement cavity and one section 13 of the placement cavity into one section 13 of the placement cavity, improving the smoothness of the vial and the support member 11 entering from two sections 15 of the placement cavity into one section 13 of the placement cavity.

[0048] As a preferred embodiment, on the basis of the above method, further, a rubber pad 16 is provided on the side surface of the limiting groove 14. The rubber pad 16 has elasticity, and the rubber pad 16 is used to increase the stability when the vial cooperates with the limiting groove 14. By providing the rubber pad 16, when the vial is placed in the limiting groove 14, the side wall of the vial can squeeze the rubber pad 16, improving the firmness of the limiting groove 14 for fixing the bottom of the vial.

[0049] The above embodiments are only used to illustrate the present invention and do not limit the technical solutions described in the present invention. Although this specification has described the present invention in detail with reference to the above respective embodiments, the present invention is not limited to the above specific embodiments.

A sterilizing device for dispensing medicine into vials, characterized in that: It comprises a placement seat, a disinfection nozzle and a driving assembly; the placement seat is provided with a placement cavity, a supporting member and a first spring are arranged in the placement cavity, one end of the first spring is connected to the supporting member, and the other end is connected to the bottom of the placement cavity, and the supporting member is used to support the bottom of the syringe bottle; the disinfection nozzle is located obliquely above the placement seat, and a first nozzle and a second nozzle are arranged on the disinfection nozzle, the first nozzle is used to spray out an airflow carrying a disinfectant, and the second nozzle is used to spray out an airflow not carrying a disinfectant; the driving assembly is used to drive the disinfection nozzle to rotate synchronously when moving toward the placement seat, so that the angle α formed between the nozzle of the disinfection nozzle and the vertical direction gradually increases; the driving assembly comprises a butt, a rack and a gear, and one side of the disinfection nozzle The abutment is rotatably connected, and the gear is fixed on the other side. The rack is vertically fixed on the placement seat, and the gear is meshed with the rack. The abutment is used to cooperate with the extraction device; when the needle on the extraction device pierces the syringe bottle, the extraction device drives the abutment and the disinfection nozzle to move synchronously toward the placement seat, and the gear rotates relative to the rack to drive the disinfection nozzle to rotate, so as to increase the angle α formed between the nozzle of the disinfection nozzle and the vertical direction; the driving assembly also includes a spring support rod, one end of which is arranged on the placement seat, and the other end is connected to the abutment; when the needle on the extraction device pierces the syringe bottle, the extraction assembly can abut against the abutment to drive the abutment to move, and the spring support rod is gradually compressed; In the process of the extraction device gradually piercing the vial, the driving assembly drives the disinfection nozzle to rotate, so that the angle α between the airflow sprayed by the disinfection nozzle and the vertical direction gradually increases, so that the action area of ​​the airflow gradually changes from the bottle stopper to the needle, and any disinfected area on the bottle stopper or the needle of the vial first contacts with the airflow sprayed from the first nozzle, and then contacts with the airflow sprayed from the second nozzle; During the whole process of the end of the needle piercing the bottle stopper, the airflow ejected from the first nozzle acts on the needle, and the airflow ejected from the second nozzle acts on the bottle stopper. The airflow ejected from the second nozzle provides a driving force to move the vial and the supporting member toward the bottom of the placement cavity, so that the first spring is compressed. After the needle pierces the bottle stopper, the airflow ejected from the first nozzle and the second nozzle acts on the needle, and the bottle stopper of the syringe bottle is not pushed by the airflow, causing the first spring to gradually restore its deformation, so that the supporting member and the syringe bottle move away from the bottom of the placement cavity.

2. The sterilizing device for dispensing medicine vials according to claim 1, characterized in that: The disinfection nozzle has an initial state. When the disinfection nozzle is in the initial state, the first nozzle sprays an airflow carrying disinfectant, so that the airflow acts on the stopper of the syringe bottle placed in the placement seat.

3. The sterilizing device for dispensing medicine vials according to claim 1, characterized in that: The placement cavity comprises a first placement cavity section, the first placement cavity section is located at the lower section of the placement cavity, the inner dimension of the first placement cavity section is adapted to the outer dimension of the supporting member, and when the supporting member is in the first placement cavity section, the first placement cavity section limits the movement direction of the supporting member, so that the movement direction of the supporting member is in the same direction as the central axis direction of the first placement cavity section; During the whole process that the end of the needle pierces the bottle stopper, the supporting member is located in a section of the placement cavity.

4. The sterilizing device for dispensing medicine vials according to claim 3, characterized in that: The supporting member is provided with a limiting groove, the inner diameter of the limiting groove is adapted to the outer diameter of the vial, and the limiting groove fixes the bottom of the vial.

5. The sterilizing device for dispensing medicine vials according to claim 3, characterized in that: The placement cavity also includes a second placement cavity section, which is located in the upper section of the placement cavity. After the needle pierces the bottle stopper, the bottle stopper of the syringe bottle is not affected by the force of the airflow, so that the first spring gradually recovers its deformation, causing the supporting member and the syringe bottle to move away from the bottom of the placement cavity, so that the supporting member moves into the second placement cavity section.

6. The sterilizing device for dispensing medicine vials according to claim 1, characterized in that: The second section of the placement cavity is open and smaller at the bottom and larger at the top. The central axis of the first spring and the central axis of the supporting member are not in a colinear state. When the needle pierces the bottle stopper and pierces the bottom of the vial, the supporting member is in the second section of the placement cavity. The first spring can bend to tilt the vial and the supporting member, so that when the end of the needle contacts the bottom of the vial, the end of the needle is located at the lowest point of the bottom of the vial.

7. The sterilizing device for dispensing medicine vials according to claim 6, characterized in that: The placement cavity section one and the placement cavity section two have a smooth transition.

8. The sterilizing device for dispensing medicine vials according to claim 4, characterized in that: A rubber pad is arranged on the side of the limiting groove, and the rubber pad is elastic and is used to increase the stability when the syringe bottle and the limiting groove are matched.
