[0022] To make the technical solution of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0023] Example 1
[0024] Combined with appendix Figure 1-4An ampoule liquid extraction and mixing structure is disclosed, suitable for scenarios where liquids from multiple ampoules are extracted and mixed for injection, reducing the need for repetitive mixing operations by medical personnel. The structure includes a mixer 1, an ampoule fixing structure 2, and a needle structure 3. The mixer 1 includes an empty cylinder 11, a piston 12 sliding inside the empty cylinder 11, and a push rod 13 fixed on the piston 12. The push rod 13 extends out of the empty cylinder 11, and the piston 12 abuts against the inner surface of the empty cylinder 11. The piston slides inside the empty cylinder 11 through the push rod 13. The piston 12 and the empty cylinder 11 are airtightly fitted, preventing gas from flowing through the empty cylinder 11 on both sides of the piston 12. The pressure in the space below the piston 12 in the empty cylinder 11 is changed by changing the position of the piston 12.
[0025] A magnetic platform 14 is fixedly mounted on the outer bottom surface of the empty cylinder 11, and a stirring magnetic bead 15 is mounted on the inner bottom surface of the empty cylinder 11. The magnetic platform 14 and the stirring magnetic bead 15 combine to form a non-contact magnetic stirrer. When the magnetic platform 14 is turned on, it drives the stirring magnetic bead 15 to rotate inside the empty cylinder 11. The rotation of the stirring magnetic bead 15 mixes the liquid inside the empty cylinder 11. The non-contact magnetic stirrer formed by the magnetic platform 14 and the stirring magnetic bead 15 is a very mature technology. The stirring magnetic bead 15 is made of permanent magnet material and has strong magnetism to induce a magnetic field. The magnetic platform 14 can generate and adjust the magnetic field. The magnetic platform 14 controls the rotation speed of the stirring magnetic bead 15 by adjusting the magnetic field strength and frequency. In the magnetic stirrer, the magnetic platform 14 generates a magnetic field of moderate strength by adjusting the current. When the stirring magnetic bead 15 is placed in the liquid or solution in the container, the magnetic field will induce the magnetism in the stirring magnetic bead 15, generating a rotational torque perpendicular to the magnetic field. Because of the magnetic attraction between the stirring bead 15 and the stirrer body, the stirring bead 15 rotates with the rotation of the magnetic field. As the magnetic field changes continuously, the stirring bead 15 will generate rotational motion in the container. This rotational motion can effectively stir the liquid or solution, making it uniformly mixed.
[0026] The bottom of the empty cylinder 11 is provided with an inlet 16 and an outlet 17 on both sides. The openings of the inlet 16 and the outlet 17 are fixedly equipped with one-way valves. The one-way valve in the inlet 16 can only allow liquid to enter the empty cylinder 11, and the one-way valve in the outlet 17 can only allow liquid to exit the empty cylinder 11. When the piston 12 is pulled upward by the push rod 13, the liquid enters through the one-way valve in the inlet 16. When the piston 12 is pushed downward by the push rod 13, the liquid exits the empty cylinder 11 through the one-way valve in the outlet 17.
[0027] The ampoule fixing structure 2 is used to fix the ampoule. It includes a top annular sleeve 21, and a bottle body limiting sleeve 22 is fixedly connected to the lower side of the top annular sleeve 21. Both the top annular sleeve 21 and the bottle body limiting sleeve 22 are hollow structures. The ampoule fixing structure 2 is tilted so that when the ampoule is installed in the ampoule fixing structure 2, it has a certain tilt angle, which makes it convenient for the needle to enter the ampoule and absorb the medicine in the ampoule. It also makes it convenient for the staff to observe the situation inside the ampoule. The ampoule fixing structure 2 is tilted towards the inside of the ampoule medicine extraction and mixing structure, so that the side of the ampoule faces the staff for easy observation.
[0028] The bottle body limiting sleeve 22 has an opening 23 located on the side of the bottle body limiting sleeve 22. The opening 23 is used to place the ampoule in the ampoule fixing structure 2 or to remove the opened ampoule from the ampoule fixing structure 2. The opening 23 is located on the side facing the outside of the ampoule liquid extraction mixing structure of the ampoule fixing structure 2. This not only makes it convenient for staff to observe the condition of the ampoule, but also prevents the ampoule from accidentally falling when placed in the ampoule fixing structure 2 due to the tilted setting of the ampoule fixing structure 2.
[0029] A sliding base plate 24 is slidably provided inside the bottom of the bottle body limiting sleeve 22. A limiting groove is provided inside the bottle body limiting sleeve 22. A connecting rod is provided at the bottom of the sliding base plate 24. The connecting rod is installed in the limiting groove. A limiting block is fixedly provided at one end of the connecting rod located in the limiting groove. The limiting block is preferably an annular protrusion protruding from the connecting rod. The annular protrusion prevents the connecting rod from coming out of the limiting groove by cooperating with the limiting groove.
[0030] A spring 25 is provided between the bottom surface of the sliding base plate 24 and the bottom surface of the bottle body limiting sleeve 22. The spring 25 continuously provides an upward elastic force to the sliding base plate 24, so that the sliding base plate 24 can cooperate with the top annular sleeve 21 to fix ampoules of any size.
[0031] The outer side of the hybrid structure is provided with a shell 4, which is directly fixedly installed on the outside of the empty cylinder 11. The shell 4 can be fixedly connected to the ampoule fixing structure 2 and fixed to the top annular sleeve 21. The shell 4 is provided with sliding grooves 41 on both sides, and a bottle opening block 42 is slidably provided in the sliding grooves 41. The bottle opening block 42 is used to open the bottle mouth of the ampoule fixed in the ampoule fixing structure 2. The side of the bottle opening block 42 facing the ampoule fixing structure 2 is provided with a conical oblique opening to facilitate the opening of the ampoule by the bottle opening block 42.
[0032] Operating rods that pass through the slide groove 41 can be provided on both sides of the bottle opener 42 to facilitate the operation of the bottle opener 42 by the staff.
[0033] The upper side of the ampoule fixing structure 2 is a needle structure 3, which is fixedly installed inside the housing 4. The needle structure 3 includes a needle groove 31 provided inside the housing 4 on the upper side of the ampoule fixing structure 2. A needle slider 32 is slidably provided in the needle groove 31. The needle slider 32 can slide in the direction of the ampoule fixing structure 2. The two sides of the needle groove 31 are through openings. The diameter of the through openings is smaller than the diameter of the needle groove 31, thereby preventing the needle slider 32 from falling out of the needle groove 31.
[0034] The needle slider 32 is provided with a handle 33 extending through the opening. The handle 33 is used for the operator to move the needle slider 31. A needle 34 is fixedly installed inside the needle slider 31. A hose 35 is connected between the end of the needle 34 and the liquid inlet 16. When the needle slider 31 slides down and drives the needle 34 to be inserted into the ampoule, the liquid in the ampoule can enter the empty cylinder 11 through the hose 35 from the needle 34. The needle 34 faces the top annular sleeve 21.
[0035] The outlet 17 can be fixed to the outlet pipe 18, which facilitates the direct discharge of the mixed liquid in the empty cylinder 11 and allows for easy connection to other pipes.
[0036] In use, install the ampoule in the ampoule fixing structure 2, press the sliding base plate 24, install the ampoule through the opening 23 into the bottle body limiting sleeve 22, and pass the ampoule mouth through the top annular sleeve 21. Release the sliding base plate 24, and the spring 25 will lift the sliding base plate 24 to fix the ampoule in the ampoule fixing structure 2. The operator pushes the opening block 42 on both sides of the opening block 42 to open the ampoule mouth. The operator pushes the handle 33 to make the needle slider 31 move the needle 34 downward to open the needle. 34 is inserted into the ampoule. At this time, the operator pulls the push rod 13 to make the piston 12 slide upward in the empty cylinder 11. The piston 12 draws the liquid in the ampoule into the empty cylinder 11. After the liquid in the ampoule in the ampoule fixing structure 2 is completely drawn out, the sliding bottom plate 24 is pressed to remove the ampoule in the ampoule fixing structure 2. After the ampoule fixing structure 2 is emptied, the ampoule containing new liquid can be fixed in the ampoule fixing structure 2 again. The above steps are repeated to draw the liquid from multiple ampoules into the empty cylinder 11.
[0037] Once the liquid to be mixed has been absorbed into the empty cylinder 11, the magnetic platform 14 is turned on. The magnetic platform 14 causes the stirring magnetic bead 15 to rotate, which in turn causes the liquid in the empty cylinder 11 to rotate, thus completing the thorough mixing.
[0038] In other embodiments, independent power structures can be connected to the needle slider 32, the bottle opener 42, and the push rod 13 to automate the extraction and mixing process.
[0039] In other embodiments, the upper side of the empty cylinder 11 has an open structure, which allows the piston 12 to be removed directly, making it convenient to clean the inside of the empty cylinder 11.
[0040] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
