Technical Field

[0001] This application relates to the technical field of medical equipment, and particularly relates to a dissolving device. Background Art

[0002] In the modern medical field, many operations that were traditionally performed manually are gradually being automated. Automation in the medical field can avoid the influence of human errors and reduce medical accidents; compared with manual operation, it can greatly improve the operation speed and medical efficiency.

[0003] Specifically, for the preparation operation of intravenous medications, a solvent needs to be injected into the medicine bottle of the intravenous medication so that the medicine dissolves in the solvent for subsequent extraction and injection. In order to fully dissolve the medicine in the medicine bottle in the solvent, manual shaking is often carried out by hand. To improve the dispensing rate, there are specialized devices for dispensing in the prior art, which shake or vibrate the medicine bottle mechanically from side to side to replace manual shaking by hand, thereby achieving rapid dissolution of the medicine.

One end of the first shaft core column 121 is fixedly connected to the bottom of the cup body 110, and the other end is fixedly connected to the first sub-transmission member 122 and the first fastener 123. The cup body assembly 100 further includes a first bearing sleeve 124. The first bearing sleeve 124 can slide relative to the first shaft core column 121. The specific structure between the first shaft core column 121 and the first bearing sleeve 124 can refer to the traditional bearing design, which will not be elaborated herein. Specifically in this embodiment of the present application, the first bearing sleeve 124 is inserted through the first support plate 130 and fixedly connected to the first support plate 130. The first sub-transmission member 122 and the cup body 110 are equivalent to an integral structure. When the first sub-transmission member 122 rotates, the first support plate 130 does not rotate, but the cup body 110 rotates accordingly.

[0019] Continuing to refer to Figure 1 , the dissolving device disclosed in the present application further includes a second support plate 300 and a second transmission member 200 corresponding to the cup body assembly 100. The second support plate 300 is disposed below the cup body assembly 100. The second transmission member 200 is inserted through the second support plate 300. The second transmission member 200 includes an upper transmission member 210 and a lower transmission member 220. The upper transmission member 210 is located above the second support plate 300 and fixedly connected to the second support plate 300. The lower transmission member 220 is located below the second support plate 300 and can rotate relative to the second support plate 300. Specifically, in combination with Figure 4A , 4B and shown in 4C, Figure 4A is a three-dimensional schematic diagram of the cup body assembly 100, the second transmission member 200 and the second support plate 300 isolated. Figure 4B is Figure 4A the partial sectional view along B-B, Figure 4C is a three-dimensional schematic diagram of the first support plate 130, the first transmission member 120 and the second transmission member 200 isolated.

[0020] The upper transmission member 210 is located above the second support plate 300 and fixedly connected to the second support plate 300. In combination with Figure 4BAs shown, the second transmission member 200 further includes a first connection portion 230 and a second bearing sleeve 240. The upper transmission member 210 is fixedly connected between the first connection portion 230 and the second bearing sleeve 240, and the first connection portion 230 is fixedly connected to the second support plate 300. The lower transmission member 220 includes a second sub-transmission member 221, a second shaft core column 222, and a second fastener 224. The second sub-transmission member 221 is fixedly connected to the second shaft core column 222 through the second fastener 224. The second shaft core column 222 is fixedly connected to the first support plate 130. The second shaft core column 222 is disposed through the second bearing sleeve 223 and is slidable relative to the second bearing sleeve 223. The specific structure may refer to a well-known bearing structure. In addition, the second shaft core column 222 further passes through the second support plate 300, the upper transmission member 210, and the first connection portion 230 and is fixedly connected to the first support 130 plate. When the second support plate 300 is stationary, the upper transmission member 210 is also stationary. At this time, when the lower transmission member 220 rotates self, the first support plate 130 rotates self accordingly.

[0021] Combined with Figure 4C As shown, the upper transmission member 210 is cooperatively provided with all the first transmission members 120 of the corresponding cup assembly 100. When the first support plate 130 rotates self, the first transmission member 120 revolves around the central axis of the first support plate 120. Since the upper transmission member 210 does not rotate self, the first transmission member 120 can rotate self.

[0022] Continue to refer to Figure 1 As shown, the dissolution device disclosed in the present application further includes a third transmission member 400. The third transmission member 400 is located below the second support plate 300. The third transmission member 400 includes an outer transmission member 410, a fixing member 420, and an inner transmission member 430. The fixing member 420 is located between the inner transmission member 430 and the outer transmission member 410. Both the inner transmission member 430 and the outer transmission member 410 can slide relative to the fixing member 420. Refer to simultaneously Figure 5As shown, the inner transmission member 430 is connected to the second support plate 300. When the inner transmission member 430 rotates, the second support plate 300 rotates accordingly. The outer transmission member 410 is arranged in cooperation with all the lower transmission members 220 of the second transmission member. When the outer transmission member 410 rotates, the lower transmission member 220 rotates accordingly; when the outer transmission member 410 is fixed and cannot rotate, and the second support plate 300 rotates, the lower transmission member 220 revolves around the central axis of the second support plate 300 while the lower transmission member 220 rotates due to the transmission relationship between the outer transmission member 400. In the above embodiment of the present application, the first transmission member 210 and the upper transmission member 210 are gear transmission, but those skilled in the art should know that the first transmission member 210 and the upper transmission member 210 can also be friction wheel transmission or other commonly used transmission methods that can achieve the purpose of the invention of the present application. Similarly, the lower transmission member 220 and the outer transmission member 410 may be gear transmission, friction wheel transmission or other transmission methods commonly used in the art to achieve the purpose of the invention of this application.

[0023] Continue to refer to Figure 1 As shown, the end of the inner transmission member 430 of the present application away from the second support plate 300 is equipped with a first power device 500, and specifically, the first power device 500 includes: a first power output device 510 and a fourth transmission member 520. The fourth transmission member 520 is arranged in cooperation with the inner transmission member 430, and when the fourth transmission member 520 rotates, the inner transmission member 430 rotates accordingly. The first power output device 510 drives the fourth transmission member 520 to rotate.

[0024] Continue to refer to Figure 1 and Figure 5 As shown, the dissolving device of the present application also includes a fifth transmission member 600 and a second power device 700. The fifth transmission member 600 is arranged in cooperation with the external transmission member 410. When the fifth transmission member 600 rotates, the external transmission member 410 rotates accordingly. When the fifth transmission member 600 is fixed and cannot rotate, the external transmission member 410 cannot rotate either. The second power device 700 includes a second power output device 710 and a sixth transmission member 720. The sixth transmission member 720 is arranged in cooperation with the fifth transmission member 600. When the sixth transmission member 720 rotates, the fifth transmission member 600 rotates accordingly. The second power output device 710 drives the sixth transmission member 720 to rotate.

[0025] In the above embodiment, the fourth transmission member 520 and the inner transmission member 430 are driven by a belt, the sixth transmission member 710 and the fifth transmission member 600 are driven by a belt, and the fifth transmission member 610 and the outer transmission member 410 are driven by gears. Of course, those skilled in the art should know that the above transmission methods can also be replaced by other methods that can achieve the purpose of the invention of this application, such as gear transmission, roller transmission, etc.

[0026] Continue to refer toFigure 1 , Figure 2 and Figure 5 As shown in Figure 2 , Figure 5 , one end of the fixing member 420 away from the second support plate 300 is connected to a plurality of support columns 800, and the support columns 800 are used to support the dissolving device on the third support plate 1000. One end of the fifth transmission member 600 close to the third support plate 1000 is connected with an auxiliary fixing device 900, and the auxiliary fixing device 900 fixes the fifth transmission member 600 on the third support plate 1000.

[0027] Combined with Figure 6 shown, Figure 6 is a sectional view of the second support plate 300, the third transmission member 400, and the fifth transmission member 600 after being isolated. The third transmission member 400 further includes an inner fixing member 421, a locking member 440, a sliding member 450, an inner rotating ring 460, and a second connecting portion 470. The inner fixing member 421 is fixedly connected to the fixing member 420; the locking member 440 is used to lock the sliding member 450 between the inner fixing member 421 and the outer transmission member 410; the inner rotating ring 460 can slide relative to the inner fixing member 421, and the outer transmission member 410 can slide relative to the inner fixing member 421. The inner transmission member 430 is fixedly connected to the second connecting portion 470 and the inner rotating ring 460, and the inner rotating ring is fixedly connected to the second support plate 300. Therefore, when the inner transmission member 430 rotates self, the third support plate 300 also rotates self.

[0028] Those skilled in the art should know that: the "self-rotation" mentioned in the above embodiments is generally understood as a certain part rotating around its central axis; the fixed connection in the present application includes both the case where two parts are independent but connected together by riveting, screw locking, adhesion, etc. and the case where two parts are integrally formed; the "cooperative setting" mentioned in the above embodiments is a general statement, that is, in order to enable two parts to achieve a transmission effect, those skilled in the art know how to reasonably design the two parts so that the two parts can cooperate with each other to achieve the transmission effect. For example, there is a necessary and appropriate close contact between the two parts. Another example is that if both parts are gears, the gears of the two parts are necessarily and moderately meshed.

[0029] The dissolving device of the present application can make the cup body 110 rotate self and also make the cup body 110 revolve around an axis outside the cup body by setting multiple sets of multi-stage transmission structures, so as to achieve a better dissolving effect and avoid foam generated by means such as oscillation; the rotation speed of the cup body can also be further accelerated to achieve a faster dissolving efficiency; in addition, each cup body 110 in the cup body assembly 100 can be controlled to rotate to a preset position according to requirements.

[0030] Specifically, for example: 1. When the first power device 500 operates and the second power device 700 does not operate, the first power device 500 can drive the inner transmission member 430 to rotate self - sufficiently, thereby driving the second support plate 300 to rotate self - sufficiently. Then the second transmission member 200 will revolve accordingly. At this time, since the second power device 700 does not operate and the outer transmission member 410 remains stationary, due to the transmission relationship between the lower transmission member 200 and the outer transmission member 410, the lower transmission member 200 rotates self - sufficiently while revolving. In this way, it can drive the first support plate 130 to rotate self - sufficiently, and the first transmission member 120 also revolves accordingly. Also, because there is no relative rotation between the upper transmission member 210 and the second support plate 300, the first transmission member 120 will also rotate self - sufficiently, thereby driving the cup body 110 to rotate self - sufficiently. 2. When it is desired to accelerate the rotation of the cup body, the second power device 700 can operate simultaneously on the basis of the operation of the first power device, driving the fifth transmission member 600 to rotate in a direction opposite to the self - rotation of the inner transmission member. That is, for example, when the inner transmission member 400 rotates counter - clockwise, the fifth transmission member 600 rotates clockwise. Thus, the outer transmission member 410 can be accelerated to rotate in the same direction as the inner transmission member 400 under the action of the fifth transmission member 600. 3. Only by relying on the first power device 500, the entire cup body assembly 100 can be rotated to any position of the second support plate. After the cup body assembly 100 rotates to the preset position, the operation of the first power device 500 can be stopped, and the second power device 700 starts to operate, driving the outer transmission member 410 to rotate self - sufficiently, and the lower transmission member 220 rotates self - sufficiently accordingly, thereby realizing the self - rotation of all cup bodies.
