Description

Technical Field

[0001] This utility model relates to medical auxiliary equipment, and more specifically, to a drug preparation device for a static compounding chamber. Background Technology

[0002] Currently, most hospital medications are prepared centrally in the intravenous preparation center. During the preparation process, medications are often stored in ampoules. Opening ampoules requires a grinding wheel. Currently, the method for opening ampoules is for medical staff to hold the grinding wheel, apply force to the side of the ampoule opening, slide it around the side of the ampoule opening, and then pry the ampoule open by hand. Since medical staff in the intravenous preparation ward prepare hundreds or thousands of medications every day, frequently using this method to open ampoules not only increases the workload of medical staff, but also makes it difficult to pry open ampoules due to deviations in the force and position of the grinding wheel when it slides along the ampoule. Furthermore, it increases the risk of hand injury during the prying process. Therefore, there is an urgent need to improve this method. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a static mixing chamber for drug preparation. Ampoules are placed in a placement groove, and a grinding wheel contacts the outer periphery of the ampoule. A sliding mechanism drives the grinding wheel to slide around the outside of the ampoule opening once along the annular groove. This not only saves effort but also improves the consistency of the force and position when cutting ampoules and makes it easier to open ampoules.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a static mixing chamber for drug preparation, comprising a base plate, a placement groove on the upper part of the base plate, a support plate detachably connected above the base plate, the support plate comprising a through hole and an annular groove coaxial with the placement groove, a sliding mechanism on the upper part of the support plate, the sliding mechanism comprising a housing, a grinding wheel connected to one side of the housing above the through hole, and the sliding mechanism being able to drive the grinding wheel to slide along the annular groove.

[0005] Furthermore, the lower part of the housing is provided with a guide platform, which is waist-shaped and inserted into an annular groove.

[0006] Furthermore, the side of the housing is provided with two connecting pieces, and a mounting groove is provided between the two connecting pieces, and the grinding wheel is installed in the mounting groove.

[0007] Furthermore, the connecting piece is provided with a guide hole, and the grinding wheel includes a limiting platform. The upper and lower sides of the limiting platform abut against two connecting pieces respectively. The upper and lower sides of the limiting platform are provided with bosses. The two bosses are respectively inserted into the corresponding guide holes. The grinding wheel can move along the guide holes to approach or move away from the axis of the placement groove.

[0008] Furthermore, a guide shaft is provided in the mounting groove, and a guide groove corresponding to the guide shaft is provided on the side of the grinding wheel. The end of the guide shaft is inserted into the guide groove, and a spring is sleeved on the outside of the guide shaft. One end of the spring abuts against the side of the mounting groove and the other end abuts against the side of the grinding wheel.

[0009] Furthermore, the mounting groove is provided with a clearance groove, and the grinding wheel can be inserted into the clearance groove.

[0010] Furthermore, the upper part of the housing is provided with a first handle, and the upper part of the protrusion located on the upper end of the limiting platform is provided with a second handle. The height of the second handle is lower than the height of the first handle, and the first handle and the second handle are located on the same straight line.

[0011] Furthermore, the base plate and the support plate are connected by a connector, which includes two diagonally arranged connecting posts and two studs. The connecting posts penetrate the support plate, and the upper end of the studs abuts against the lower end of the support plate.

[0012] Furthermore, the upper end of the stud is provided with a protrusion that penetrates the support plate. The upper part of the base plate is provided with connecting sleeves near the four corners. The lower ends of the connecting post and the stud are respectively inserted into the corresponding connecting sleeves. The connecting sleeve and the stud are connected by threads. Rotating the stud can drive the support plate to rise and fall.

[0013] Furthermore, a limiting sleeve is provided inside the placement slot.

[0014] In summary, this utility model has the following beneficial effects:

[0015] When it is necessary to cut the ampoule neck with a grinding wheel, medical staff can manually rotate the sliding mechanism. The sliding mechanism can then move one revolution along the annular groove, allowing the grinding wheel to move one revolution against the ampoule neck, thereby achieving the cutting of the ampoule neck. The movement trajectory of the grinding wheel and the position of the grinding wheel relative to the ampoule are limited, which improves the force and positional accuracy of the grinding wheel in cutting the ampoule and facilitates the opening of the ampoule. During the cutting operation, a spring allows the grinding wheel to apply force to the surface of the ampoule neck, eliminating the need for manual force application to the ampoule. This not only saves the effort of medical staff but also improves the consistency of the cutting force during the movement of the grinding wheel. The design of the grinding wheel being able to move along the guide hole can meet the cutting needs of ampoules with different neck widths, making it widely applicable. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 4 As shown, this embodiment discloses a drug preparation tool for a static compounding chamber, including a base plate 1. The base plate 1 has a placement groove 11 on its upper part, into which ampoules can be placed and positioned. A support plate 2 is detachably connected to the upper part of the base plate 1. The support plate 2 includes a through hole 21 coaxial with the placement groove 11 and an annular groove 22. A sliding mechanism 4 is provided on the upper part of the support plate 2. The sliding mechanism 4 includes a housing 41. A grinding wheel 5 is connected to one side of the housing 41 above the through hole 21. A guide platform 43 is provided at the lower part of the housing 41. The guide platform 43 is waist-shaped and is inserted into... The sliding mechanism 4, inserted into the annular groove 22, drives the grinding wheel 5 to slide along the annular groove 22. Through the cooperation of the guide table 43 and the annular groove 22, when it is necessary to cut the ampoule mouth with the grinding wheel 5, medical staff can manually rotate the sliding mechanism 4, which can then move one revolution along the annular groove 22, so that the grinding wheel 5 moves one revolution against the ampoule mouth, thereby achieving the cutting of the ampoule mouth. The movement trajectory of the grinding wheel 5 is limited, and the position of the grinding wheel 5 and the ampoule is limited, which can improve the force and positional accuracy of the grinding wheel cutting the ampoule, and facilitate the opening of the ampoule.

[0023] The housing 41 has two connecting pieces 44 on its side, and a mounting groove 46 is provided between the two connecting pieces 44. The grinding wheel 5 is installed in the mounting groove 46. The connecting pieces 44 have guide holes 45. The grinding wheel 5 includes a limiting platform 51, and the upper and lower sides of the limiting platform 51 abut against the two connecting pieces 44 respectively. The upper and lower sides of the limiting platform 51 have protrusions 52, and the two protrusions 52 are respectively inserted into the corresponding guide holes 45. The grinding wheel 5 can move along the guide holes 45 to approach or move away from the axis of the placement groove 11. Specifically, the mounting groove 46 is located within the mounting groove 46. A guide shaft 48 is provided in the mounting groove 46. The side of the grinding wheel 5 is provided with a guide groove 54 corresponding to the guide shaft 48. The end of the guide shaft 48 is inserted into the guide groove 54. A spring 6 is sleeved on the outside of the guide shaft 48. One end of the spring 6 abuts against the side of the mounting groove 46 and the other end abuts against the side of the grinding wheel 5. During the cutting operation, the spring 6 enables the grinding wheel 5 to apply force to the surface of the ampoule mouth, eliminating the need for manual force application to the ampoule. This not only saves the effort of medical staff but also improves the consistency of the cutting force during the movement of the grinding wheel 5.

[0024] The design of the grinding wheel 5, which can move along the guide hole 45, can meet the cutting operations of ampoules with different mouth widths, and has a wide range of applications.

[0025] The mounting groove 46 is provided with a clearance groove 47, and the grinding wheel 5 can be inserted into the clearance groove 47. By setting the clearance groove 47, the grinding wheel 5 can be provided with a space to move and make way.

[0026] The upper part of the housing 41 is provided with a first handle 42, and the upper part of the protrusion 52 located at the upper end of the limiting platform 51 is provided with a second handle 53. The height of the second handle 53 is lower than the height of the first handle 42. The first handle 42 and the second handle 53 are located on the same straight line. By setting the first handle 42, the movement of the sliding mechanism 4 can be facilitated. Since the cut part of the ampoule mouth is often concave, in order to ensure that the grinding wheel 5 can hold this part, when the ampoule is placed, when installing the sliding mechanism 4, medical staff can hold the first handle 42 and the second handle 53 with their hands, and pull the grinding wheel 5 away from the ampoule through the second handle 53 to avoid the grinding wheel 5 contacting the ampoule when installing the sliding mechanism 4.

[0027] The base plate 1 and the support plate 2 are connected by a connector 3. The connector 3 includes two diagonally arranged connecting posts 31 and two studs 32. The connecting posts 31 penetrate the support plate 2, and the upper end of the studs 32 abuts against the lower end of the support plate 2. Specifically, the upper end of the studs 32 is provided with a protrusion 33, which penetrates the support plate 2. The upper part of the base plate 1 is provided with connecting sleeves 12 near the four corners. The lower ends of the connecting posts 31 and studs 32 are respectively inserted into the corresponding connecting sleeves 12. The connecting sleeves 12 and studs 32 are connected by threads. Rotating the studs 32 can drive the support plate 2 to rise and fall. Through the above design, not only can the detachable design of the support plate 2 be realized, but the height of the support plate 2 can also be adjusted, thereby meeting the cutting operation of ampoules of different heights.

[0028] The placement slot 11 is equipped with a limiting sleeve 7. Since there are only a few sizes of ampoules used in hospitals, the position of the ampoule can be limited by setting a limiting sleeve 7 that matches the size of the ampoule used in the hospital. Specifically, when using an ampoule with a diameter of 10 mm, the matching limiting sleeve 7 is inserted into the placement slot 11, and then the ampoule is placed in the limiting sleeve 7. The position of the ampoule is limited by the matching limiting sleeve 7, which facilitates the cutting operation of the ampoule.

[0029] In this embodiment, a slot for placing a marker pen 8 and a slot for placing a pry bar 9 can also be provided on the upper part of the base plate 1. The marker pen 8 can be used for writing and recording, and the pry bar 9 can be used to pry open the bottle opening of solvents such as saline solution.
