DETAILED DESCRIPTION

In addition, the terms "first", "second", and "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", and "set" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or it can be the internal connection of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. The following is an explanation of the embodiments of the present utility model based on the overall structure of the present utility model.

[0021] Reference Figures 1 to 5In the embodiment of the utility model, a push-type penicillin and physiological saline quick-mixing device with automatic calibration of volume ratio comprises: a mixing box 1 and an upper cavity 2, a partition sealing layer 3 is fixedly arranged below the upper cavity 2, a lower cavity 4 is fixedly arranged below the partition sealing layer 3, a docking block 5 is fixedly arranged on the side of the partition sealing layer 3, the upper cavity 2 is fixedly arranged above the docking block 5, the lower cavity 4 is fixedly arranged below the docking block 5, a pressing plate 6 is inserted on the outside of the partition sealing layer 3, a spring sleeve 7 is fixedly arranged on the inside of the partition sealing layer 3, a spring 8 is arranged inside the spring sleeve 7, a push rod 9 is fixedly arranged on the side of the spring 8, a limit rod 10 is fixedly arranged on the side of the push rod 9, a rubber limit block 11 is fixedly arranged on the side of the limit rod 10, a limit groove 12 is provided on the inside of the docking block 5, and a sealing rubber pad 13 is fixedly arranged on the side of the spring sleeve 7.

[0022] The above scheme is adopted: the setting of the separation sealing layer 3 effectively isolates the upper cavity 2 and the lower cavity 4, ensuring that the penicillin solution and the physiological saline do not contact each other before mixing, thereby avoiding the risk of contamination and cross infection. The setting of the sealing rubber pad 13 further enhances the sealing performance of the device and prevents liquid from penetrating into the spring sleeve 7 and other components.

[0023] A liquid inlet end 14 is fixedly arranged above the upper cavity 2 , and a lower liquid hole 15 is opened below the upper cavity 2 .

[0024] The above scheme is adopted: the lower liquid hole 15 is a channel for the penicillin solution to flow from the upper cavity 2 into the lower cavity 4. Before the pressing plate 6 is pressed, the lower liquid hole 15 is closed to prevent the penicillin solution from flowing out in advance. When the pressing plate 6 is pressed, the lower liquid hole 15 is opened through the action of the mechanical structure, allowing the penicillin solution to flow out and mix with the physiological saline.

[0025] A crank 16 is provided on the outside of the lower cavity 4, and a rotating shaft 17 is rotatably connected to the side of the crank 16. A stirring blade 18 is clamped on the surface of the rotating shaft 17. A first rubber plug 19 is fixedly provided at one end of the outer side of the lower cavity 4, a second rubber plug 20 is fixedly provided below the lower cavity 4, and a handle 21 is fixedly provided on the side of the mixing box 1.

[0026] The above solution is adopted: the design of the crank 16 allows the user to drive the stirring blade 18 to rotate with only one hand, without the need for additional tools or complicated operating steps, thereby improving the simplicity and efficiency of operation. By holding the handle 21, the user can operate the device more stably to avoid accidents or shaking during mixing or moving.

[0027] The mixing box 1 is made of transparent glass material for easy observation. The partition sealing layer 3 and the docking block 5 are on the same horizontal plane. The pressing plate 6 is fixedly connected to the spring 8 on the inner side of the spring sleeve 7 through the outer side of the partition sealing layer 3. The pressing plate 6 pushes the limit rod 10 and the rubber limit block 11 into the limit groove 12 through the spring 8. The size of the limit groove 12 is compatible with the size of the limit rod 10 and the rubber limit block 11. The rubber limit block 11 is a raised block, and its width is slightly larger than the width of the limit rod 10.

[0028] With the above solution, the size of the limiting groove 12 is adapted to the limiting rod 10 and the rubber limiting block 11, which can ensure that they are accurately aligned and positioned during the pressing process to prevent deviation or misalignment.

[0029] The lower liquid hole 15 is located directly above the push rod 9 , and an end cover is inserted above the liquid inlet end 14 .

[0030] With the above solution, the provision of the end cover can effectively protect the liquid inlet end 14 from the intrusion of dust, bacteria and other pollutants.

[0031] The first rubber stopper 19 and the second rubber stopper 20 can be pulled out and replaced, the crank 16 drives the rotating shaft 17 to rotate by manual shaking, the stirring blades 18 are provided in multiple groups, the first rubber stopper 19 can be injected with medicine through a syringe, and the second rubber stopper 20 can be used to extract the mixed liquid medicine through a syringe.

[0032] The above scheme is adopted: the multiple groups of stirring blades 18 can generate stronger stirring force when the rotating shaft 17 rotates, so that the penicillin solution and the normal saline are fully mixed in a short time, thereby improving the mixing efficiency. The design of the first rubber stopper 19 allows the user to easily inject normal saline or other medicines into the device through a syringe, avoiding the risk of contamination and leakage caused by opening the device. The design of the second rubber stopper 20 allows the user to easily extract the mixed liquid medicine through a syringe, which is convenient for subsequent use or injection.

[0033] The working principle of the utility model is as follows: the upper cavity 2 of the device is used to store penicillin solution, while the lower cavity 4 is used to store saline solution. The two cavities are isolated by a separation sealing layer 3 to ensure that penicillin and saline solution do not contact each other before mixing. First, the user presses the pressing plate 6, and this action compresses the spring 8 in the spring sleeve 7. As the spring 8 is compressed, the push rod 9 and the limit rod 10 and rubber limit block 11 connected thereto are pushed into the limit groove 12 on the inner side of the docking block 5. Since the width of the rubber limit block 11 is slightly larger than the width of the limit rod 10, it can fit more closely in the limit groove 12 to ensure the sealing effect of the upper and lower cavities. Then, an appropriate amount of penicillin is added through the liquid inlet end 14 above the upper cavity 2. The penicillin solution is injected into the lower cavity 4 through the first rubber stopper 19, and then the pressing plate 6 is pressed again. As the spring 8 opens, the push rod 9 drives the limiting rod 10 and the rubber limiting block 11 to be pulled out of the limiting groove 12 in the docking block 5. Since the pressing plate 6 moves outward a certain distance due to the opening of the spring 8, the push rod 9 is driven to shrink into the spring sleeve 7, leaving a gap for the lower liquid hole 15 to flow, thereby opening the hole, so that the penicillin solution in the upper cavity 2 can flow into the lower cavity 4. Since the lower cavity 4 is pre-stored with physiological saline, the penicillin solution and the physiological saline will be mixed in the mixing box 1. Due to the relatively soft nature of the rubber limiting block 11, the limiting rod 10 and the rubber limiting block 11 will naturally flow out of the mixing box 1. The spring sleeve 7 is pulled out from the limiting groove 12. Sealing rubber pads 13 are provided on both sides of the spring sleeve 7 to prevent liquid from entering the spring sleeve 7. In order to enhance the mixing effect, a crank 16 is provided on the outside of the lower cavity 4. The user can drive the rotating shaft 17 to rotate by shaking the crank 16, thereby driving the stirring blade 18 to rotate. The rotation of the stirring blade 18 can accelerate the mixing process of the penicillin solution and the physiological saline to ensure that the two are fully mixed. After the mixing is completed, the user can use a syringe to extract the mixed liquid for skin testing through the second rubber stopper 20 under the lower cavity 4. After use, since the first rubber stopper 19 and the second rubber stopper 20 are inserted into both sides of the lower cavity 4, they can be pulled out and replaced, and the sealing mechanism in the separation sealing layer 3 is closed to make the upper The cavity 2 is separated from the lower cavity 4, and then the liquid inlet end 14 of the upper cavity 2 is opened to pour in the disinfectant liquid to disinfect the interior of the upper cavity 2, and then the pressing plate 6 is pressed to retract the push rod 9 into the spring sleeve 7, and then the disinfectant liquid is poured in to disinfect the interior of the upper cavity 2, and then the pressing plate 6 is pressed to retract the push rod 9 into the spring sleeve 7, and then enter the lower cavity 4 for disinfection, and then because the device uses a transparent glass material that is convenient for observation, the disinfection situation can be observed. After the disinfection of the lower cavity 4 is completed, the second rubber stopper 2 is pulled out to discharge the disinfectant liquid. In addition, the upper cavity 2 can also be injected with physiological saline, and it does not necessarily have to specifically accommodate penicillin solution. Penicillin powder can also be added to the lower cavity 4, and the first rubber stopper 19 on the side of the lower cavity 4 is pulled out and the penicillin powder is poured in.

[0034] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
