[0018] Preferably, the bowl-shaped body is threadedly connected to the connecting rod.

[0019] Compared with the prior art, the embodiments of the present invention have the following advantages and beneficial effects:

[0020] 1. A rapid dissolver for injectable drugs provided by an embodiment of the utility model has a cover body arranged on the dissolving kettle body to provide a closed dissolving space, and then a guide hole is arranged on the cover body, and an agitator is passed through the guide hole so that it can rotate and move up and down in the guide hole, thereby ensuring that the agitator can sufficiently stir the solid and liquid in the dissolving kettle body, and the supporting mechanism can ensure the stability of the dissolving kettle body during the entire dissolving and stirring process to prevent excessive splashing of the drug liquid.

[0021] The key invention point of the embodiment of the utility model is that the agitator is set as a structure composed of a connecting rod and a bowl-shaped body, and the bowl-shaped body opens downward in the dissolving kettle body. The operator can apply force to the connecting rod to drive the bowl-shaped body to rotate or displace axially in the dissolving kettle body. When the bowl-shaped body rotates, the liquid and solid in the dissolving kettle body can be rotated and stirred. In the process of the axial movement of the bowl-shaped body, it can move to the lower edge of the opening of the bowl-shaped body to contact the bottom of the dissolving kettle body and squeeze each other. The reaction force at the bottom of the dissolving kettle body can deform the bowl-shaped body, so that the fluid inside the bowl-shaped body can be discharged instantly. Since a through hole is provided on the bowl-shaped body, the through hole can slowly balance the pressure difference between the inside and outside of the bowl-shaped body, so that the winding body can be squeezed back and forth in the axial direction and then restored. In the process of squeezing, the liquid and solid in the dissolving kettle body can be disturbed, especially the solid can shuttle between the two sides of the through hole, and can also collide back and forth in the bowl-shaped body, thereby improving the stirring efficiency. At the same time, the bowl-shaped arc structure with an opening downward has a guiding effect, which can reduce splashing during stirring.

[0022] 2. The bowl-shaped body is set to a structure that can cover the discharge port, so as to disturb the solids at the uneven parts of the discharge port, thereby preventing the solids from adhering to the uneven parts of the discharge port and causing uneven dissolution.

[0023] 3. The first stirring blade is set on the bowl-shaped body through an elastic component. By utilizing the shrinkage deformation characteristics of the elastic body, the first stirring blade can stir the bottom of the dissolving kettle body without affecting the pressure difference formed by squeezing the inside and outside of the bowl-shaped body and the dissolving kettle body. At the same time, the first stirring blade is set within the coverage range of the bowl-shaped body. During the stirring process, the bowl-shaped body has the function of limiting the liquid from splashing upward.

[0024] In general, the embodiment of the utility model provides a rapid dissolver for injectable drugs by providing an agitator with a bowl-shaped body and opening a through hole in the bowl-shaped body to utilize the pressure difference to achieve upward mixing of the solid medicine at the bottom, thereby achieving the purpose of rapid stirring and preventing splashing.

[0035] Example

[0036] like Figure 1As shown, an embodiment of the utility model provides a rapid dissolver for injection drugs, including a dissolving kettle body 1, which is used to contain drug liquids and solids and provide a dissolving space. The upper end of the dissolving kettle body 1 is open and covered with a cover body 2. The cover body 2 covers the dissolving kettle body 1 to form a closed containing space to prevent the drug reagent from being contaminated during the dissolving process. A guide hole is provided on the cover body 2, and a stirrer is passed through the guide hole. The guide hole is used to install the stirrer, so that one end of the stirrer is inside the dissolving kettle body 1 and the other end is outside the dissolving kettle body 1. The operator can apply force to the exposed stirrer, thereby transmitting power to the liquid and solid in the dissolving kettle body 1, so that the solid is dissolved faster and the liquid concentration is mixed evenly. In the embodiment of the utility model, the stirrer can not only rotate on the cover body 2, but also move up and down along the guide hole. A supporting mechanism is provided at the bottom of the dissolving kettle body 1, and the supporting mechanism is used to support the entire dissolver to ensure that the device maintains relative stability during the entire dissolving process and prevent the dissolved liquid from splashing. In the embodiment of the utility model, the structure of the agitator is improved. Specifically, the agitator includes a connecting rod 3 and a bowl-shaped body 4. The connecting rod 3 passes through the cover body 2, and the bowl-shaped body 4 opens downward. One end of the connecting rod 3 is connected to the bowl-shaped body 4, that is, the connecting rod 3 is arranged on both sides of the cover body 2, one side of which is arranged in the dissolving kettle body 1, and is connected to the bowl-shaped body 4 in the dissolving kettle body 1. The bowl-shaped body opens downward and is provided with a plurality of through holes 5; the bowl-shaped body 4 can be squeezed and deformed with the bottom of the dissolving kettle body 1, and when the pressure between the bowl-shaped body 4 and the dissolving kettle body 1 is zero, the bowl-shaped body 4 can return to its original state.

[0037] Specifically, the bowl-shaped body 4 is made of a material with certain elastic properties, which can be a material such as rubber, and is not limited here. When the operator applies force to the connecting rod 3, the axial movement of the bowl-shaped body 4 in the dissolving kettle body 1 can be controlled, that is, the bowl-shaped body 4 can be controlled to move away from or close to the bottom of the dissolving kettle body 1. When the bowl-shaped body 4 contacts the bottom of the dissolving kettle body 1 ( Figure 1 and Figure 3 ), at this time, the connecting rod 3 can continue to be applied with a vertical downward force to increase the pressure between the bowl-shaped body 4 and the dissolving kettle body 1, so that the bowl-shaped body 4 is deformed, so that the fluid in the bowl-shaped body 4 will be squeezed out, and a pressure difference will be instantly formed inside and outside the bowl-shaped body 4. Since a plurality of through holes 5 are provided on the bowl-shaped body 4, and since the pressures on both sides of the through holes 5 are equal, the fluid and solid outside the through holes 5 will be pressed into the through holes 5 and enter the interior of the bowl-shaped body 4. When the fluid and solid pass through the through holes 5, they will disturb the solid and liquid in the dissolving kettle body 1, thereby achieving the purpose of stirring. What is important is that when the fluid replaces the solid and is pressed into the bowl-shaped body 4, it has a large kinetic energy, so after entering the bowl-shaped body 4, it will continue to move in the bowl-shaped body 4, and collide with the side wall of the bowl-shaped body 4, and then change the direction of movement to achieve mixing disturbance.

[0038] When the through hole 5 reduces the pressure difference between the inside and outside of the bowl-shaped body 4, force can be applied to the connecting rod 3 to smoothly separate the bowl-shaped body 4 from the dissolving kettle body 1 instantly ( Figure 2 ), during this process, the solid medicine precipitated at the bottom of the dissolving kettle body 1 will also be sucked into the bowl-shaped body 4 due to the pressure difference, and collide in the bowl-shaped body 4, thereby promoting the dissolution efficiency. The operator can repeatedly operate the above process by controlling the movement of the connecting rod 3 in the axial direction, thereby achieving the purpose of rapid dissolution and uniform dissolution. It should be noted that the connection method between the bowl-shaped body 4 and the connecting rod 3 is not limited here, as long as the purpose of stable connection can be achieved, it can be bonding, clamping, threaded connection, etc. In order to improve the flexibility of the device, as a preferred embodiment of the utility model, the bowl-shaped body 4 and the connecting rod 3 are detachably connected by threaded connection, which is convenient for subsequent maintenance and replacement of the bowl-shaped body 4. At the same time, the bowl-shaped body 4 opens downward, and during the rotation process, it is driven to rotate by the arc surface. Since the radius of the lower end of the bowl-shaped structure is larger, the fluid flow rate is also greater than that of the upper end, so that a pressure difference can be formed, resulting in a lower pressure at the lower end of the bowl-shaped structure than at the upper end, which serves the purpose of reducing splashing.

[0039] In the embodiment of the utility model, in order to facilitate the liquid taking, the discharge port 6 is set at the lower part of the dissolving kettle body 1, and a discharge valve is set at the discharge port 6 to control the opening and closing of the discharge port 6. The structure is generally uneven during the closing process, which will cause the drug solids to easily adhere to the discharge port 6, resulting in a low dissolution efficiency. In order to solve this problem, the discharge port 6 can be set at the bottom of the dissolving kettle body 1, and the discharge valve is set on the discharge port 6. At the same time, the position of the bowl-shaped body 4 is restricted. Specifically, when the bowl-shaped body 4 and the bottom of the dissolving kettle body 1 are squeezed, the bowl-shaped body 4 covers the discharge port 6. In this way, the bowl-shaped body 4 can use the internal and external pressure difference to apply force to the solid and liquid at the discharge port 6 to improve the uniformity of stirring. Preferably, the axis line of the bowl-shaped body 4 coincides with the axis line of the discharge port 6, that is, when the bowl-shaped body 4 is squeezed with the bottom of the dissolving kettle body 1, the discharge port 6 is located at the center of the bowl-shaped body 4, so that the bowl-shaped body 4 exerts a more intense force on the liquid and solid near the discharge port 6, and the stirring degree is better. Of course, in other embodiments, the bowl-shaped body 4 and the discharge port 6 are not limited to being coaxially arranged, as long as the purpose of covering the discharge port 6 when the bowl-shaped body 4 contacts the bottom of the dissolving kettle body 1 can be achieved.

[0040] Furthermore, a first stirring blade 7 is provided in the bowl-shaped body 4, and the first stirring blade 7 is connected to the bowl-shaped body 4 through an elastic component. When the elastic component is in a free state, the first stirring blade 7 is exposed to the bowl-shaped body 4; when the elastic component is deformed, the first stirring blade 7 can be hidden in the bowl-shaped body 4. Specifically, the first stirring blade 7 is suspended in the bowl-shaped body 4 and connected to the bowl-shaped body 4 through an elastic component. When the elastic component contracts, the first stirring blade 7 can be driven to move, thereby being hidden in the bowl-shaped body 4. Such a structure can ensure that the first stirring blade 7 will not hinder the contact and compression between the bowl-shaped body 4 and the bottom of the dissolving kettle body 1. At the same time, when the elastic component is in a free state, the first stirring blade 7 is exposed to the bowl-shaped body 4. In the process of rotating the bowl-shaped body 4, the first stirring blade 7 can stir the bottom of the dissolving kettle body 1, further improving the stirring efficiency. Since the bowl-shaped body 4 covers the first stirring blade 7, the stirring of the first stirring blade 7 can be prevented from splashing. As a preferred embodiment of the utility model, the bottom of the dissolving kettle body 1 can be set to be convex downward to an arc shape ( Figure 1 ), which can improve the discharge thoroughness of the discharge port 6. Of course, in other embodiments, it can also be directly set as a flat plate structure ( Figure 3 ), there is no restriction here, as long as the purpose of convenient material arrangement can be achieved.

[0041] In order to further improve the dissolution uniformity at the discharge port 6, the position of the first stirring blade 7 can be specifically set. For example, when the first stirring blade 7 contacts the bottom of the dissolving kettle body 1, the first stirring blade 7 can cover the discharge port 6. In this way, the first stirring blade 7 can cover the entire discharge port 6 during the stirring process, avoiding the risk of the discharge port 6 being easily adhered to solids or liquids due to insufficient flatness. In order to further improve the dissolution efficiency, a spiral blade 8 ( Figure 1 and Figure 3 ), the spiral blade 8 is arranged in the dissolving kettle body 1 and above the bowl-shaped body 4, playing an auxiliary stirring role. Of course, in other embodiments, a second stirring blade 9 ( Figure 2 ), the second stirring blade 9 is arranged in the dissolving kettle body 1 and is arranged above the bowl-shaped body 4. The above two methods can be realized. The specific setting can be malicious according to actual needs and is not limited here. The spiral blade 8 and the second stirring blade 9 form a superimposed stirring effect with the bowl-shaped body 4 and the first stirring blade 7 during the stirring process, thereby further improving the dissolution rate.

[0042] In order to improve the stability of the dissolver of the utility model during the stirring process, the support mechanism is set to include a first support leg 10 and a second support leg 11 that are symmetrically arranged on both sides. The mutually symmetrical first support leg 10 and the second support leg 11 can prevent the dissolver from tilting or moving due to external vibration or unstable factors during use, which helps to ensure that the dissolver remains stable during operation, thereby improving the dissolution efficiency and operational safety. Of course, in order to improve the operator's operating comfort, a handle 12 can be set at the other end of the connecting rod 3, and the handle 12 is provided with anti-skid patterns. The handle 12 is arranged on the outside of the dissolving kettle body 1. This structure allows the operator to easily control the movement of the stirrer. The anti-skid pattern design of the handle 12 can ensure that the operator can hold it firmly when the stirrer is running and is not easy to slide, thereby increasing the safety and stability of the operation. At the same time, the handle 12 is arranged on the outside of the dissolving kettle body 1, so that the operator can more conveniently control the movement of the stirrer during operation. It should be noted that in the embodiment of the utility model, the kinetic energy of the connecting rod 3 can be directly applied by the operator, and can also be controlled by connecting the motor to the movement of the connecting rod 3. There is no restriction here, and it can be set according to actual conditions.

[0043] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model. It should be noted that the structures or components illustrated in the drawings are not necessarily drawn to scale, and the utility model omits the description of known components and processing technologies and processes to avoid unnecessary limitations on the utility model.
