Description

Technical Field

[0001] The invention relates to the technical field of mixing, and in particular to a pharmaceutical solution mixing device and an operating method thereof. Background Art

[0002] Pharmacy is a comprehensive applied technical discipline that studies drug preparation theory, production technology, and quality control. Its basic task is to study how to make drugs into suitable dosage forms and ensure that high-quality preparations meet the needs of medical and health work. Since the principles and technical operations of prescription preparation and preparation are roughly the same, the discipline that discusses the two parts together is called pharmacy. Modern pharmacy has made great progress and also includes biopharmaceutics, physical pharmacy, etc.

[0003] At present, pharmaceutical solutions have been widely used in our production and life. Most of the pharmaceutical solutions need to be mixed to achieve better results. The complex mixing equipment still used now is not convenient for production and use, and will reduce the mixing effect of chemical solutions, affecting the normal use of chemical solutions in the later stage. Summary of the invention

[0004] The object of the present invention is to overcome the defects of the prior art and provide a pharmaceutical solution mixing device and an operating method thereof.

[0005] The technical solution to achieve the purpose of the present invention is: a pharmaceutical solution mixing device, comprising a main cabinet, the main cabinet comprising two symmetrical cabinet cavities, the cabinet cavities are connected to a mixing box, the mixing box comprising:

[0006] A stirring plate rotatably connected to the middle of the mixing box,

[0007] A box bottom hinged plate hinged to the bottom of the mixing box;

[0008] Both ends of the stirring plate are provided with stirring plate tensioning bags that are interference fit with the mixing box body. The stirring plate tensioning bag is penetrated by an opening and closing bolt that is sealed and connected. The opening and closing bolt includes an opening and closing bolt cap and an opening and closing bolt rod that are integrally formed. The opening and closing bolt rod is used to touch the hinged plate of the box bottom when the stirring plate rotates, and the opening and closing bolt cap is used to open and close the stirring plate tensioning bag under the drive of the opening and closing bolt rod.

[0009] The stirring plate tensioning bag described in the above technical solution is slidably connected to a stirring plate tensioning bag pressure plate, and the stirring plate tensioning bag pressure plate is limitedly slidably connected to the opening and closing bolt rod, and the stirring plate tensioning bag pressure plate is used to squeeze the interior of the stirring plate tensioning bag.

[0010] The opening and closing bolt rod described in the above technical solution is connected with an opening and closing bolt tensioning bag, the opening and closing bolt tensioning bag is located between the stirring plate tensioning bag pressure plate and the stirring plate tensioning bag, and the opening and closing bolt tensioning bag spring is connected to the stirring plate tensioning bag.

[0011] When the opening and closing plug cap of the above technical solution is sealed and connected to the stirring plate tensioning bag, the spring between the opening and closing plug tensioning bag and the stirring plate tensioning bag is in a stretched state.

[0012] The stirring plate tensioning bag pressure plate described in the above technical solution includes a wave elastic plate portion, and the wave elastic plate portion is used to tension the stirring plate tensioning bag pressure plate to the stirring plate tensioning bag.

[0013] The wave elastic plate portion described in the above technical solution is hinged with a T-shaped plate, and the T-shaped plate is provided with a T-shaped plate through hole.

[0014] The stirring plate described in the above technical solution is hollow inside and is provided with a plurality of supplementary bags evenly spaced apart, and the supplementary bag pipeline is connected to the stirring plate tensioning bag.

[0015] The stirring plate described in the above technical solution has stirring plate through holes arranged in an array at the upper and lower ends, and the stirring plate through holes located at the lower end of the stirring plate are arranged in two rows and are offset from the supplementary capsule.

[0016] The above technical solution has three rows of stirring plate through holes at the upper end of the stirring plate, corresponding one-to-one to the supplementary capsules, and the stirring plate through holes at the upper end of the stirring plate are elastically provided with one-way sealing balls corresponding to the supplementary capsules.

[0017] A method for operating a pharmaceutical solution mixing device comprises the following steps:

[0018] Step 1: When mixing is required, the stirring plate is driven by the power source to drive the stirring plate tensioning bag to squeeze toward the mixing box, and the stirring plate tensioning bag is compressed and retracted.

[0019] The stirring plate rotates counterclockwise to mix the two pharmaceutical solutions located on the upper and lower sides of the stirring plate in the mixing box;

[0020] Step 2: After the stirring plate rotates counterclockwise, when the opening and closing bolt rod of the stirring plate tensioning bag touches the hinged plate at the bottom of the box, the reverse force pushes the opening and closing bolt cap away from the stirring plate tensioning bag, the stirring plate tensioning bag opens, and the catalyst inside the stirring plate tensioning bag enters into the two pharmaceutical solutions.

[0021] After adopting the above technical solution, the present invention has the following positive effects:

[0022] (1) The stirring plate of the present invention is driven by the power source motor to accelerate the mixing reaction of the two chemical solutions by rotating them. When the stirring plate continues to rotate, the opening and closing bolt rod touches the hinged plate at the bottom of the box, and the opening and closing bolt cap pushes away from the stirring plate tensioning bag to open it, allowing the catalyst inside to enter the two chemical solutions, thereby accelerating the mixing reaction of the two chemical solutions. After the hinged plate at the bottom of the box is hit and rotated by the stirring plate, it rebounds to its original position, and the two chemical solutions are also stirred in the process.

[0023] (2) The stirring plate tensioning bag of the present invention is slidably connected to the stirring plate tensioning bag pressure plate, which can squeeze the catalyst inside the stirring plate tensioning bag, thereby facilitating the extrusion of the catalyst and accelerating the mixing reaction of the two reagent solutions.

[0024] (3) The closing bolt tensioning bag spring of the present invention is connected to the stirring plate tensioning bag. When the opening and closing bolt cap is pushed open and the catalyst begins to move out, the opening and closing bolt tensioning bag can assist in pushing the catalyst out under the elastic restoring force of the spring.

[0025] (4) The stirring plate tensioning bag pressure plate of the present invention includes a wave elastic plate portion, which can make the stirring plate tensioning bag pressure plate tensioned on the stirring plate tensioning bag. The wave elastic plate portion is hinged with a T-shaped plate, and the T-shaped plate is provided with a T-shaped plate through hole, which can screen and re-crush the catalyst that may contain agglomerates and impurity blocks through the reciprocating rotation of the T-shaped plate at a small angle.

[0026] (5) The stirring plate tension bag pipeline of the present invention is connected to a replenishing bag, which can replenish the liquid catalyst to the stirring plate tension bag.

[0027] (6) The stirring plate of the present invention is provided with stirring plate through holes arranged in an array at the upper and lower ends, and arranged in a staggered manner with the supplementary capsule. When the stirring plate rotates to stir and mix the two pharmaceutical solutions, the stirring plate through holes at the upper and lower ends of the stirring plate allow the pharmaceutical solutions to pass through them, thereby reducing the rotational resistance of the pharmaceutical solution to the stirring plate.

[0028] (7) The stirring plate through hole at the upper end of the stirring plate of the present invention is elastically provided with a stirring plate through hole one-way sealing ball corresponding to the supplementary capsule. After the supplementary capsule replenishes the catalyst and is gradually compressed, the one-way sealing ball of the stirring plate through hole is no longer supported, so that the stirring plate through hole at the upper end of the stirring plate is connected to the stirring plate through hole at the lower end of the stirring plate, so that the pharmaceutical solution passes through the stirring plate, reducing the rotational resistance of the pharmaceutical solution to the stirring plate.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0041] Example 1, see Figures 1 to 5 The present invention provides a pharmaceutical solution mixing device, including a main cabinet 100, the main cabinet 100 includes two symmetrical cabinet cavities 101, the cabinet cavities 101 are connected to a mixing box 200, and the mixing box 200 includes:

[0042] The stirring plate 201 is rotatably connected to the middle of the mixing box 200.

[0043] A bottom hinge plate 202 hinged to the bottom of the mixing box 200;

[0044] Both ends of the stirring plate 201 are provided with stirring plate tensioning capsules 203 which are interference-fitted with the mixing box 200. The stirring plate tensioning capsule 203 is penetrated and sealed with an opening and closing plug 204. The opening and closing plug 204 includes an opening and closing plug cap 2041 and an opening and closing plug rod 2042 which are integrally formed.

[0045] The opening and closing bolt rod 2042 is used to contact the hinged plate 202 at the bottom of the box when the stirring plate 201 rotates, and the opening and closing bolt cap 2041 is used to open and close the stirring plate tensioning bag 203 under the drive of the opening and closing bolt rod 2042.

[0046] This embodiment is a basic embodiment of the present invention. A control box 102 is further arranged between the two symmetrical cabinet cavities 101 of the main cabinet 100. A storage rack 103 and a heating rod 104 are arranged inside the cabinet cavity 101. The control box 102 is used to control the entire main cabinet 100. The storage rack 103 is used to place the mixing box 200. The heating rod 104 is used to heat the water inside the cabinet cavity 101 and maintain a constant temperature.

[0047] The mixing box 200 is mainly used to mix two pharmaceutical solutions. The stirring plate 201 is a circular plate located in the middle of the mixing box 200. It is connected to the mixing box 200 by interference fit through the stirring plate tensioning capsule 203. The stirring plate 201 can be driven by a power source motor (not shown in the figure). One of the two pharmaceutical solutions is located below the stirring plate 201, and the other is located above the stirring plate 201. The pharmaceutical solution above the stirring plate 201 can be added in advance or added immediately. The stirring plate tensioning capsule 203 is a deformable capsule, and a catalyst for catalyzing the reaction of the two pharmaceutical solutions is pre-set inside it. The catalyst can be powder or liquid, and there is no excessive restriction in this embodiment. It can be understood that due to the interference fit attached to the stirring plate 201, the pharmaceutical solutions above and below the stirring plate 201 will not mix when the stirring plate 201 does not rotate. The pharmaceutical solutions above and below can be adapted to different outlets, and each pharmaceutical solution can be used separately in different usage scenarios.

[0048] When mixing is required, the stirring plate 201 is driven by the power source motor to drive the stirring plate tensioning capsule 203 to squeeze toward the mixing box 200. After the stirring plate tensioning capsule 203 is compressed and retracted, it no longer has an interference fit with the mixing box 200, so that the stirring plate 201 can rotate. The stirring plate 201 starts to rotate counterclockwise, and the two pharmaceutical solutions located on the upper and lower sides of the stirring plate 201 in the mixing box 200 start to mix. Afterwards, the stirring plate 201 continues to stir the two pharmaceutical solutions under the rotation of the power source motor to accelerate the mixing reaction of the two.

[0049] During the continuous counterclockwise rotation of the stirring plate 201, when the opening and closing bolt rod 2042 of the stirring plate tensioning capsule 203 touches the bottom hinged plate 202, the opening and closing bolt cap 2041 is pushed away from the stirring plate tensioning capsule 203 due to the reverse force, the stirring plate tensioning capsule 203 opens, and the catalyst inside the stirring plate tensioning capsule 203 enters the two pharmaceutical solutions, accelerating the mixing reaction of the two pharmaceutical solutions. It should be noted that the bottom hinged plate 202 can be hinged to the mixing box 200 with a torsion spring, and the bottom hinged plate 202 will rebound to its original position after being hit by the stirring plate 201 and rotating clockwise, and the two pharmaceutical solutions can also be stirred in this process.

[0050] Example 2, see Figures 1 to 5This embodiment is an optimized embodiment of embodiment 1. The difference between this embodiment and the embodiment is that the stirring plate tension capsule 203 is slidably connected to the stirring plate tension capsule pressure plate 205, the stirring plate tension capsule pressure plate 205 is limitedly slidably connected to the opening and closing bolt rod 2042, and the stirring plate tension capsule pressure plate 205 is used to squeeze the inside of the stirring plate tension capsule 203. The stirring plate tension capsule pressure plate 205 divides the stirring plate tension capsule 203 into layers, and a layer of the stirring plate tension capsule pressure plate 205 and the opening and closing bolt cap 2041 is used to store the catalyst. When the stirring plate tension capsule 203 touches the inner wall of the mixing box 200, it is squeezed and deformed, and the stirring plate tension capsule pressure plate 205 squeezes out the catalyst in the stirring plate tension capsule 203, so as to accelerate the mixing reaction of the two reagent solutions.

[0051] As an optimization of this embodiment, the opening and closing bolt rod 2042 is connected to the opening and closing bolt tensioning capsule 206, the opening and closing bolt tensioning capsule 206 is located between the stirring plate tensioning capsule pressure plate 205 and the stirring plate tensioning capsule 203, and the opening and closing bolt tensioning capsule 206 is spring-connected to the stirring plate tensioning capsule 203. In the case where there is a catalyst between the stirring plate tensioning capsule pressure plate 205 and the opening and closing bolt cap 2041, after the opening and closing bolt cap 2041 is pushed away from the stirring plate tensioning capsule 203, it drives the opening and closing bolt tensioning capsule 206 to press out the catalyst.

[0052] As an optimization of this embodiment, when the opening and closing bolt cap 2041 is sealed and connected to the stirring plate tensioning capsule 203, the spring between the opening and closing bolt tensioning capsule 206 and the stirring plate tensioning capsule 203 is in a stretched state. The stretched state here is because there is a catalyst filling between the stirring plate tensioning capsule pressure plate 205 and the opening and closing bolt cap 2041, so that the opening and closing bolt tensioning capsule 206 is pressed away from the opening and closing bolt cap 2041 and approaches the opening and closing bolt rod 2042, thereby making the spring in a stretched state. When the opening and closing bolt cap 2041 is pushed open and the catalyst begins to move out, the opening and closing bolt tensioning capsule 206 assists in pushing out the catalyst under the elastic restoring force of the spring.

[0053] In this embodiment, the stirring plate tensioning capsule pressure plate 205 includes a wave elastic plate portion 2051, and the wave elastic plate portion 2051 is used to tension the stirring plate tensioning capsule pressure plate 205 to the stirring plate tensioning capsule 203. The wave elastic plate portion 2051 enables the stirring plate tensioning capsule pressure plate 205 to deform with the assistance of the wave elastic plate portion 2051 when the catalyst is added between the stirring plate tensioning capsule pressure plate 205 and the opening and closing plug cap 2041, thereby increasing the amount of catalyst and tensioning the stirring plate tensioning capsule pressure plate 205 to the stirring plate tensioning capsule 203.

[0054] In this embodiment, the catalyst is in powder form and may contain clots, impurity blocks, etc. The wave elastic plate portion 2051 is hinged with a T-shaped plate 207, and the T-shaped plate 207 is provided with a T-shaped plate through hole 2071. When the stirring plate tensioning bag 203 is squeezed, the wave elastic plate portion 2051 is compressed and deformed, driving the T-shaped plate 207 to rotate clockwise at a small angle. Through the reciprocating rotation at a small angle, the catalyst that may contain clots and impurity blocks is screened and re-crushed using the T-shaped plate through hole 2071.

[0055] Example 3, see Figures 1 to 5 The difference between this embodiment and the embodiment is that the catalyst is in liquid state, the stirring plate 201 is hollow inside, and is provided with a plurality of evenly spaced supplementary capsules 208, and the supplementary capsules 208 are connected to the stirring plate tensioning capsule 203 by a pipeline. The supplementary capsules 208 are filled with liquid catalyst, and the stirring plate tensioning capsules 203 are supplemented after the catalyst in the stirring plate tensioning capsules 203 is squeezed out.

[0056] In this embodiment, the stirring plate 201 is provided with array-arranged stirring plate through holes 209 at the upper and lower ends, and the stirring plate through holes 209 at the lower end of the stirring plate 201 are provided with two rows, which are staggered with the supplementary capsule 208. When the stirring plate 201 rotates to stir and mix the two pharmaceutical solutions, the stirring plate through holes 209 at the upper and lower ends of the stirring plate 201 can allow the pharmaceutical solutions to pass through, thereby reducing the rotational resistance of the pharmaceutical solutions to the stirring plate 201.

[0057] In this embodiment, the stirring plate through hole 209 at the upper end of the stirring plate 201 is provided with three rows, corresponding to the supplementary capsules 208 one by one, and the stirring plate through hole 209 at the upper end of the stirring plate 201 is elastically provided with a stirring plate through hole one-way sealing ball 210 corresponding to the supplementary capsule 208. When the inside of the supplementary capsule 208 is full of catalyst, the supplementary capsule 208 presses against the stirring plate through hole one-way sealing ball 210 to seal the stirring plate through hole 209. After the catalyst in the supplementary capsule 208 supplements the stirring plate tensioning capsule 203 with catalyst, the supplementary capsule 208 is gradually compressed and no longer presses against the stirring plate through hole one-way sealing ball 210, and the stirring plate through hole one-way sealing ball 210 leaves the stirring plate through hole 209 at the upper end of the stirring plate 201 under the elastic force. The stirring plate through hole 209 at the upper end of the stirring plate 201 is connected to the stirring plate through hole 209 at the lower end of the stirring plate 201 , so that the drug solution passes through the stirring plate 201 , reducing the rotation resistance of the drug solution to the stirring plate 201 .

[0058] The specific embodiments described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
