Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to a sterilizing device for dispensing medicines into vials. Background Art

[0002] At present, in the process of dispensing medicine, it is usually necessary to transfer the powdered medicine in the vial to the infusion bottle so that the medicine can be injected into the human body through the vein. Specifically, a syringe first sucks up part of the liquid medicine, and then the needle of the syringe is inserted into the stopper of the vial, so that the liquid medicine in the syringe is injected into the vial through the needle. After the powdered medicine in the vial is dissolved in the liquid medicine, the syringe is used to extract the liquid medicine in the vial, and then the extracted liquid medicine is transferred to the infusion bottle.

[0003] However, the inventors have found that there are still some deficiencies in the current dispensing operation, specifically: When dispensing medicine, it is usually necessary to disinfect the vial stopper to prevent the contaminants on the vial stopper from entering the vial during the needle piercing the stopper, thereby contaminating the medicine in the vial. At present, when disinfecting the vial stopper, a cotton swab is usually used for disinfection. Disinfectant is dripped onto the cotton swab, and then the vial stopper is wiped with the cotton swab to reduce the contaminants on the vial stopper. However, manual disinfection is time-consuming and laborious, and it is difficult to ensure the disinfection quality of each vial. In addition, before the needle pierces the stopper, the outer wall of the needle may be contaminated by the external environment. During the process of the needle piercing the stopper, the outer wall of the needle may carry contaminants into the vial. As a result, it is difficult to disinfect the vial stopper and the needle of the syringe at the same time with the current disinfection method, which increases the risk of contamination of the medicine in the vial during the dispensing process.

[0004] Therefore, based on the above-mentioned shortcomings, there is an urgent need to design a sterilizing device for dispensing vials, so as to achieve the purpose of sterilizing the stopper and needle of the vial at the same time, and reduce the risk of contamination of the medicine in the vial during the dispensing process. Summary of the invention

[0005] The purpose of the present invention is to provide a syringe bottle disinfection device for dispensing medicines in view of the above-mentioned shortcomings that occur during the current dispensing operation, so as to achieve the purpose of simultaneously disinfecting the stopper and needle of the syringe bottle and reduce the risk of contamination of the medicine in the syringe bottle during the dispensing process.

[0006] In order to achieve the above technical purpose, the technical solution adopted by the present invention is: A sterilizing device for dispensing a vial of a syringom, comprising a placement seat, a sterilizing 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 vial of the syringom; the sterilizing nozzle is located obliquely above the placement seat, and a first nozzle and a second nozzle are arranged on the sterilizing nozzle, the first nozzle is used to spray out an airflow carrying a sterilizing solution, and the second nozzle is used to spray out an airflow not carrying a sterilizing solution; the driving assembly is used to drive the sterilizing nozzle to rotate synchronously when moving toward the placement seat, so that the angle α formed between the nozzle of the sterilizing nozzle and the vertical direction gradually increases; 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.

[0007] As a preferred technical solution of the present application, the driving assembly includes a resistance member, a rack and a gear. One side of the disinfection nozzle is rotatably connected to the resistance member, and the other side is fixed with the gear. The rack is vertically fixed on the placement seat, and the gear is meshed with the rack. The resistance member is used to cooperate with the extraction device. When the needle on the extraction device pierces the syringe bottle, the extraction device drives the resistance member 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, thereby increasing the angle α formed between the nozzle of the disinfection nozzle and the vertical direction.

[0008] As a preferred technical solution of the present application, the driving assembly also includes a spring support rod, one end of which is arranged on a placement seat, and the other end is connected to a resistance piece; in the process of the needle on the extraction device piercing the vial of syringe, the extraction assembly can resist the resistance piece to drive the resistance piece to move, and the spring support rod is gradually compressed.

[0009] 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 airflow carrying disinfectant, so that the airflow acts on the stopper of the syringe bottle placed in the placement seat.

[0010] As a preferred technical solution of the present application, the placement cavity includes a placement cavity section, the placement cavity section is located at the lower section of the placement cavity, the inner dimension of the placement cavity section is adapted to the outer dimension of the supporting member, and when the supporting member is in the placement cavity section, the 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 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.

[0011] As a preferred technical solution of the present application, a limiting groove is formed on the supporting 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.

[0012] As a preferred technical solution of the present application, the placement cavity also includes a second section of the placement cavity, and the second section of the placement cavity 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 section of the placement cavity.

[0013] As a preferred technical solution of the present application, the second section of the placement cavity is open in a smaller lower part and larger upper part, and 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 stopper and pierces the bottom of the vial, the supporting member is in the second section of the placement cavity, and 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.

[0014] As a preferred technical solution of the present application, there is a smooth transition between the first and second placement chamber sections.

[0015] As a preferred technical solution of the present application, a rubber pad is provided on the side of the limiting groove, and the rubber pad is elastic and is used to increase the stability of the syringe bottle when it cooperates with the limiting groove.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. In the scheme of the present application, a disinfection nozzle is provided so that when the disinfection nozzle is in an initial state, the disinfection nozzle sprays an airflow carrying disinfectant, so that the airflow 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 angle α gradually increases, so that the area acted by the airflow 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 airflow carrying disinfectant acts on the needle but not on the stopper. , so that in the process of the needle piercing the stopper of the vial, the airflow carrying the disinfectant can be prevented from impacting the piercing point on the stopper, thereby preventing the airflow carrying the disinfectant from entering the vial from the piercing point, and preventing the disinfectant from contaminating the liquid in the vial. At the same time, in the process of the needle gradually piercing the vial, the driving component continuously drives the disinfection nozzle to rotate, so that the angle α continues to increase, thereby increasing the area on the needle that is disinfected by the airflow, and further improving the effect of the needle being disinfected. In this way, the disinfection device of the present application can simultaneously disinfect the vial stopper and the needle, and can reduce the risk of the medicine in the vial being contaminated during the dispensing process; 2. Furthermore, by providing the first nozzle and the second nozzle, when the extraction device pierces the vial and the airflow is used to disinfect the vial stopper or needle of the vial, any area to be disinfected on the vial stopper or needle of the vial first contacts with the airflow ejected from the first nozzle, and then contacts with the airflow ejected from the second nozzle. Thus, the airflow ejected from the second nozzle without the disinfectant can impact the vial stopper or needle disinfected by the disinfectant, so as to reduce the residual disinfectant on the vial stopper or needle, and increase the volatilization speed of the residual disinfectant, thereby further improving the disinfection effect of the bottle cap or needle. 3. Furthermore, by setting up the second section of the placement cavity, after the needle pierces the bottle stopper, the airflows ejected from the first nozzle and the second nozzle act on the needle but not on the bottle stopper. When the bottle stopper of the vial is not pushed by the airflow, the first spring gradually recovers its deformation, and the elastic force provided by the first spring can overcome the friction between the side wall of the needle and the bottle stopper, so that the supporting member and the vial move away from the bottom of the placement cavity. In this way, the time for the needle to penetrate from the bottle stopper to the bottom of the bottle can be saved, and the movement of the vial and the medicine in the vial can be intensified, and the dissolution efficiency between the powdered medicine and the liquid medicine in the vial can be further improved. At the same time, after the first spring gradually recovers its deformation, the force required to increase the deformation of the first spring can be reduced, so that after the needle penetrates the bottom of the vial, the risk of collision 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. 4. Furthermore, the second section of the placement cavity is open, and 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 then pierces the bottom of the vial, the supporting member and the vial can be placed in the second section of the placement cavity, and 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 colinear with the central axis of the supporting member. In this way, the piercing point is not in the direction of the central axis of the first spring, and on the basis of the force applied by the side wall of the needle to the bottle stopper, the first spring is bent, and the second section of the placement cavity in an open state provides a movable space, so that the vial and the supporting member are tilted, 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, so that when the extraction device absorbs the liquid in the vial, the residual medicine in the vial can be further reduced, and in the process of the vial tilting, the dissolution of the powdered medicine in the vial can be further accelerated.

[0025] Embodiment 1: This embodiment provides a sterilizing device for dispensing medicine vials, see Figure 1-Figure 4As shown, it includes a placement seat 1, a disinfection nozzle 2 and a driving assembly 3. The placement seat 1 is used to place a syringe bottle. The disinfection nozzle 2 is located obliquely above the placement seat 1. A first nozzle 8 is provided on the disinfection nozzle 2. The disinfection nozzle 2 has an initial state. When the disinfection nozzle 2 is in the initial state, the first nozzle 8 of the disinfection nozzle 2 faces the central area of ​​the placement seat 1. The driving assembly 3 is used to drive the disinfection nozzle 2 to rotate, so that the angle α formed between the first nozzle 8 of the disinfection nozzle 2 and the vertical direction gradually increases. In the initial state, the disinfection nozzle 2 sprays an airflow carrying disinfectant through the first nozzle 8, and the airflow acts on the stopper of the syringe bottle placed in the placement seat 1 to disinfect the stopper; before the needle on the extraction device pierces the stopper of the syringe bottle, as the needle gradually approaches the syringe bottle, the driving component 3 drives the disinfection nozzle 2 to rotate, so that the angle α formed between the first nozzle 8 of the disinfection nozzle 2 and the vertical direction gradually increases, so that the area acted by the airflow gradually changes from the stopper to the side wall of the needle; as the needle gradually pierces the syringe bottle, the driving component 3 continues to drive the disinfection nozzle 2 to rotate, and the angle α continues to increase.

[0026] In the present application, a disinfection nozzle 2 is provided, so that when the disinfection nozzle 2 is in an initial state, the disinfection nozzle 2 sprays an airflow carrying disinfectant, and the airflow acts on the stopper of the vial placed in the placement seat 1, 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 3 drives the disinfection nozzle 2 to rotate, so that the angle α formed between the first nozzle 8 of the disinfection nozzle 2 and the vertical direction gradually increases, so that the area acted by the airflow gradually changes from the stopper to the side wall of the needle on the upper part of the stopper, thereby simultaneously disinfecting the stopper and the needle, and before the needle pierces the stopper of the vial, the airflow carrying the disinfectant It acts on the needle but not on the bottle stopper, so that in the process of the needle piercing the bottle stopper of the syringe bottle, the airflow carrying the disinfectant can be prevented from impacting the piercing point on the bottle stopper, thereby preventing the airflow carrying the disinfectant from entering the syringe bottle from the piercing point, and preventing the disinfectant from contaminating the medicine in the syringe bottle. At the same time, in the process of the needle gradually piercing the syringe bottle, the driving component 3 continuously drives the disinfection nozzle 2 to rotate, so that the angle α continues to increase, thereby increasing the area on the needle that is disinfected by the airflow, and further improving the effect of the needle being disinfected. In this way, the disinfection device of the present application can disinfect the bottle stopper and the needle of the syringe bottle at the same time, and can reduce the risk of the medicine in the syringe bottle being contaminated during the dispensing process.

[0027] As a preferred embodiment, on the basis of the above-mentioned method, the driving assembly 3 includes a butt 4, a rack 5 and a gear 6. One side of the disinfection nozzle 2 is rotatably arranged on the butt 4, and the gear 6 is fixed on the other side. The rack 5 is vertically fixed on the placement seat 1. The gear 6 is meshed with the rack 5. The butt 4 is used to cooperate with the extraction device. In the process of the needle on the extraction device piercing the syringe bottle, the extraction device cooperates with the butt 4, and the extraction device drives the butt 4 and the disinfection nozzle 2 to move synchronously in the direction close to the syringe bottle. In this process, the meshing position of 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 angle α gradually increases, so that the airflow ejected from the disinfection nozzle 2 sequentially disinfects the bottle stopper and the needle of the syringe bottle, thereby improving the convenience of disinfection.

[0028] As a preferred embodiment, on the basis of the above method, further, the driving assembly 3 also includes a spring support rod 7, one end of the spring support rod 7 is arranged on the placement seat 1, and the other end is connected to the abutment 4; in the process of the needle on the extraction device piercing the syringe bottle, the extraction device can abut against the abutment 4 to drive the abutment 4 to move, and the spring support rod 7 is gradually compressed; after the liquid medicine in the syringe bottle is sucked into the extraction device, in the process of pulling the needle out of the syringe bottle, the extraction device moves in the direction away from the placement seat 1, and at this time the spring support rod 7 gradually restores its deformation, so that the abutment 4 also moves in the direction away from the placement seat 1, so that it is convenient to automatically reset the abutment 4 and the disinfection nozzle 2.

[0029] Embodiment 2: Based on the technical solution of embodiment 1, further, see Figure 1-Figure 4 As shown, the disinfection nozzle 2 further includes a second nozzle 9, which is located behind the first nozzle 8 in the rotation direction when the disinfection nozzle 2 moves toward the placement seat 1. The second nozzle 9 is used to spray out an airflow that does not carry disinfectant. When the extraction device pierces the vial and the airflow disinfects the bottle stopper or needle of the vial, any disinfected area on the bottle stopper or needle of the vial first contacts with the airflow sprayed from the first nozzle 8, and then contacts with the airflow sprayed from the second nozzle 9. In this way, the airflow sprayed from the second nozzle 9 that does not carry disinfectant can impact the bottle stopper or needle disinfected by the disinfectant, so as to reduce the residual disinfectant on the bottle stopper or needle, increase the volatilization speed of the residual disinfectant, and further improve the disinfection effect of disinfecting the bottle cap or needle.

[0030] As a preferred embodiment, on the basis of the above-mentioned manner, further, a placement cavity 10 is provided on the placement seat 1, and a supporting member 11 and a first spring 12 are provided 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, and 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, and when the vial is placed on the supporting member 11, the first spring 12 can play a buffering role, which can reduce the impact on the bottom of the vial at the moment when the vial is placed on the supporting member 11, thereby reducing the risk of the vial breaking.

[0031] As a preferred embodiment, on the basis of the above-mentioned method, further, the placement cavity 10 includes a placement cavity section 13, the placement cavity section 13 is located in the lower section of the placement cavity 10, and the inner dimension of the placement cavity section 13 is adapted to the outer dimension of the supporting member 11; when the supporting member 11 is in the placement cavity section 13, the placement cavity section 13 limits the movement direction of the supporting member 11, so that the movement direction of the supporting member 11 is in the same direction as the central axis direction of the placement cavity section 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 syringe bottle, so as to fix the bottom of the syringe bottle. During the whole process of the end of the needle piercing the bottle 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 bottle stopper. The airflow ejected from the second nozzle 9 provides a driving force to move the syringe bottle and the supporting member 11 toward the bottom of the placement cavity 10, so that the first spring 12 is compressed and the supporting member 11 is placed in the first section 13 of the placement cavity. After the supporting member 11 is limited by the first section 13 of the placement cavity, the stability of the needle piercing the bottle stopper can be improved. At the same time, the setting of the limiting groove 14 improves the stability of the relative position between the syringe bottle and the supporting member 11.

[0032] As a preferred embodiment, on the basis of the above-mentioned manner, further, the placement cavity 10 also includes a second placement cavity section 15, and the second placement cavity section 15 is located in the upper section of the placement cavity 10. After the needle pierces the bottle stopper, the airflow ejected from the first nozzle 8 and the second nozzle 9 acts on the needle, and the bottle stopper of the syringe bottle is not pushed by the airflow, so that the first spring 12 gradually restores its deformation. The elastic force provided by the first spring 12 can overcome the friction between the side wall of the needle and the bottle stopper, so that the supporting member 11 and the syringe bottle move away from the bottom of the placement cavity 10, so that the supporting member 11 is in the second placement cavity section 15. In this way, the time for the needle to penetrate from the bottle stopper to the bottom of the bottle can be saved, and the movement of the vial and the medicine in the vial can be intensified, which can further improve the dissolution efficiency between the powdered medicine 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 penetrates the bottom of the vial, the risk of collision between the end of the needle and the bottom of the vial can be further reduced, which can further prevent the needle from being damaged.

[0033] Embodiment 3: Based on the technical solution of Embodiment 2, further, see Figure 1-Figure 4 As shown, the second section 15 of the placement cavity is open, and the central axis of the first spring 12 is not in a colinear state with the central axis of the supporting member 11. When the needle pierces the bottle stopper and pierces the bottom of the vial, the supporting member 11 is in the second section 15 of the placement cavity, and the first spring 12 can bend to tilt the vial and the supporting member 11, 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. The insertion point on the vial for needle insertion is located on the central axis of the vial, and the central axis of the vial is colinear with the central axis of the supporting member 11. In this way, the insertion point is not in the direction of the central axis of the first spring 12, and the first spring 12 is bent on the basis of the force applied by the side wall of the needle to the bottle stopper, and the second section 15 of the open placement cavity provides a movable space, so that the vial and the supporting member 11 are tilted, 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, so that when the extraction device draws the liquid in the vial, the residual medicine in the vial can be further reduced, and in the process of the vial tilting, the dissolution of the powdered medicine in the vial can be further aggravated; there is a movable space in the placement cavity 10 that allows the first spring 12 to bend.

[0034] As a preferred embodiment, on the basis of the above-mentioned method, further, there is a smooth transition between the placement chamber section 13 and the placement chamber section 2 15, so that after the vial is placed on the supporting member 11, the airflow ejected from 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 supporting member 11 slides into the placement chamber section 13 along the side walls of the placement chamber section 2 15 and the placement chamber section 13, thereby improving the smoothness of the vial and the supporting member 11 entering from the placement chamber section 2 15 into the placement chamber section 13.

[0035] As a preferred embodiment, on the basis of the above-mentioned manner, further, a rubber pad 16 is provided on the side of the limiting groove 14, and the rubber pad 16 is elastic and is used to increase the stability of the vial when it 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, thereby improving the firmness of the limiting groove 14 in fixing the bottom of the vial.

Although the present invention has been described in detail with reference to the above embodiments, the present invention is not limited to the above specific implementation methods.
