Example 1

The invention provides a shaking table for blood collection tubes to achieve blood mixing by shaking. The entire device can be placed on a horizontal platform to uniformly shake the blood collection tubes, and a universal wheel is provided at the bottom of the entire device. When the blood collection tubes are stored in the device, When there are many blood vessel samples, the entire device can be pushed to move on the horizontal platform, which greatly saves manpower in moving. In the present invention, a first elastic member 130 is provided on the outside of the tube connection platform 120 to cooperate with the movement of the buffering and stabilizing body 200. Not only does it ensure that the blood collection tube can reach a regular number of shakings after being positioned on the tube connection platform 120, but also the elastic force and fluid force in the buffering and stabilizing body 200 cooperate to make the blood collection tube gradually stabilize during the shaking process. , first of all, it solves the problem of shaking the blood collection tube for a long time and avoids the violent shaking of the blood collection tube, so that the blood cells in the blood collection tube will not be destroyed by the violent shaking. The following is the shaking method of the blood collection tube described above to achieve blood circulation. The specific structural analysis and implementation of the mixing shaker are as follows:

Referring to Figures 1 to 6, a shaking table for blood collection tubes to achieve blood mixing by rocking means includes a tube support body 100 and a buffering and smooth body 200 arranged on the tube support body 100. The tube support body 100 Include at least:

The fixed platform 110 has a tube connecting platform 120 hinged on the inner side of the fixed platform 110. The fixed platform 110 is used to support the tube connecting platform 120. The surface of the tube connecting platform 120 is preset with a third connector that can be connected with the blood collection tube. a connecting cavity 122;

The first elastic member 130 is composed of a first spring and a rod. A bracket 111 is symmetrically arranged on the surface of the fixed platform 110. The rod of the first elastic part 130 is fixedly connected to the bracket 111. The first elastic part 130 is used for Provide elastic movement force to the pipe body connecting platform 120;

Buffering stationary body 200, buffering stationary body 200 at least includes:

The second elastic member 210 is composed of a fixed rod 211 and a second spring 212. The fixed rod 211 is fixedly connected to the pipe connection platform 120. The second elastic member 210 is used to provide elastic reset to the pipe connection platform 120. force;

The stabilizer 220 is located on the side of the second elastic member 210. The stabilizer 220 includes a liquid tube 221. A stabilizer rod 222 is provided inside the liquid tube 221. One end of the stabilizer rod 222 is connected to the fixed rod 211, and the stabilizer rod 222 is connected to the fixed rod 211. The other end of 222 is connected to a connecting portion 223. A closed chamber is formed between the connecting portion 223 and the liquid tube 221. Fluid can be placed in the chamber. The surface of the liquid tube 221 is connected to a second connecting arm 225. The second connecting arm 225 The side is connected to the second spring 212. The second connecting arm 225 is used to support the liquid pipe 221 and the second spring 212. The stabilizing rod 222 and the connecting part 223 can cooperate with the movement of the fixed rod 211, and the stabilizing member 220 will The elastic motion force provided by the second elastic member 210 and the first elastic member 130 is hydraulically buffered.

When the above-mentioned tube support body 100 and buffering and stabilizing body 200 perform specific operations, the blood collection tube is inserted along the first connection cavity 122 on the tube connection platform 120, so that the blood collection tube is positioned on the tube. On the body connecting platform 120, one end of the pipe connecting platform 120 can be pressed downward with the hand to provide a downward force on the pipe connecting platform 120. At this time, the pipe connecting platform 120 tilts upward along the inner side of the fixed platform 110. , the blood collection tube undergoes the first shaking motion, and the first elastic member 130 on the other end of the tube connecting platform 120 will receive the upward compression force from the end of the tube connecting platform 120, and the first elastic component 130 will press against the tube body. The connecting platform 120 provides a downward compression reset force. At this time, the blood collection tube on the tube connecting platform 120 forms a second shaking. During the initial downward movement of the end of the tube connecting platform 120, the fixed rod 211 will then move downward, the fixed rod 211 cooperates with the second spring 212 to form an elastic force, and the second spring 212 will also give an elastic rocking restoring force to the pipe connection platform 120. At this time, the second elastic member 210 and the first elastic member 211 will move downward. The elastic movement of the member 130 will cause the blood collection tube on the tube connection platform 120 to rock violently. This is the first back-and-forth rocking movement of the blood collection tube. As the fixed rod 211 initially moves downward, the stabilizing rod 222 This will drive the connecting part 223 to move along with the movement of the fixed rod 211. Due to the closed sliding of the connecting part 223 and the liquid pipe 221, and the fluid is preset inside the chamber between the connecting part 223 and the liquid pipe 221, when the connecting part 223 follows When the stabilizing rod 222 moves sideways, the chamber space formed by the connecting part 223 and the liquid pipe 221 becomes larger, and the measurement of the air in the chamber becomes inconvenient, causing the pressure in the chamber to become smaller. Under the action of atmospheric pressure, the pressure in the chamber is removed from the chamber. The fluid will be pressed to one side with the movement of the connecting part 223 (as shown in Figure 12, D is the direction of fluid movement). At this time, when the tube connecting platform 120 is subjected to the second elastic member 210 and the first elastic When the member 130 moves under the elastic restoring force, the connecting part 223 squeezes the fluid to reset, and simultaneously forms a hydraulic buffering force for reset, so that the reset movement range of the pipe body connecting table 120 becomes smaller, so that the pipe body connecting table 120 is subjected to After the first hand pressure is exerted, the movement of the tube connecting table 120 will no longer be violent, and will gradually move to a stable state, so that the blood collection tube will only shake violently for the first time, ensuring blood collection. The blood in the tube will not be subject to strenuous exercise to avoid damage to blood cells;

Secondly, as the movement of the first elastic member 130 and the second elastic member 210 cooperates, the smooth member 220, the second elastic member 210 and the first elastic member 130 cooperate with each other. After the pipe connection platform 120 is pressed for the first time, , the cooperation of the elastic force and the hydraulic buffering force in the stabilizer 220 ensures that the number of shaking movements of the tube connecting table 120 is synchronously limited, and does not cause multiple back and forth shaking movements of the tube connecting table 120, causing the blood in the blood collection tube to Just mix it with the anticoagulant, ensuring the accuracy of the blood test, and because it will not shake violently, the blood collection tube will be stably connected in the first connection chamber 122, and there will be no interference with the tube connection platform. 120 Risk of being thrown out by violent shaking.

The bottom of the fixed table 110 is fixedly connected through a support plate, and a shaft 121 is installed on the inside of the shaft 121. The shaft 121 is rotated on the fixed table 110. A hand pressing table 123 is installed on one end of the pipe connecting table 120, which is located at The support at the bottom is also equipped with a universal wheel to facilitate personnel to push the entire device on a horizontal table, which greatly saves the physical strength of medical staff who work for a long time, and can be done by touching the hand pressure table 123 with the hand. The tube connection table 120 is pressed downward, and the surface of the hand pressure table 123 is provided with finger grooves that fit the fingers, so that the medical staff can perform pressure by placing their fingers here, and it is convenient enough.

For some specific blood collection tube blood samples, the number of times the blood collection tube and blood need to be shaken needs to be larger, so the strength of the medical staff's hands when initially pressing the hand pressure table 123 can be increased to meet the needs of the blood collection tube and blood. number of shakes to mix.

Example 2

Considering that under greater pressure, in order to further ensure that the blood collection tube will not be thrown out of the first connection chamber 122 under great pressure, this embodiment makes further improvements based on Embodiment 1, such as As shown in Figure 7 and Figure 8:

A contact piece 140 is provided below the pipe connection platform 120. The contact piece 140 includes a connecting plate 141. The connecting plate 141 is provided with a second connecting cavity 142 that is adapted to the first connecting cavity 122. The second connecting cavity 142 is used for To support the bottom of the blood collection tube, an adjustment arm 144 is provided on the surface of the second connection cavity 142. The adjustment arm 144 is fixedly connected to the shaft 121. The bottom of the blood collection tube can be in contact with the second connection cavity 142 on the surface of the connection plate 141. , thereby contacting and fixing the bottom side of the blood collection tube, and the connection between the adjusting arm 144 and the shaft 121 cooperates, the connecting plate 141 will shake synchronously with the shaft 121 driving the tube connection platform 120 to ensure that the blood collection tube will not It is thrown out of the pipe body connecting platform 120 .

Considering that when the tube body connection platform 120 and the connection plate 141 are horizontal, the distance between the tube body connection platform 120 and the connection plate 141 cannot be changed. When the length and size of the blood collection tube are larger or smaller according to the actual situation, The second connection cavity 142 on the connection plate 141 cannot be adapted to the current bottom contact support of the blood collection tube. A first connection arm 143 slides on the inside of the adjustment arm 144. The first connection arm 143 is fixedly connected to the connection plate 141, and the adjustment arm 144 and the first connecting arm 143 have connection ports 145 left on their surfaces. The connection ports 145 are plugged and locked through the connecting rod 146, eliminating the fixed connection between the bottom of the adjusting arm 144 and the connecting plate 141 directly. According to the actual length of the blood collection tube size, adjust the current position by sliding the first connecting arm 143 in the adjusting arm 144, so that the connecting plate 141 moves upward or downward away from the tube connecting table 120, ensuring that the bottom of the blood collection tube located in the first connecting chamber 122 can be stuck When inside the second connection chamber 142, the connecting rod 146 locks the adjusting arm 144 and the first connecting arm 143 along the connecting port 145 at the corresponding position, and the position of the connecting plate 141 is locked to achieve adaptive support for the bottom of the blood collection tube, making the contact Part 140 is more suitable for the current actual situation.

Example 3

Considering that if the liquid pipe 221 is directly arranged in a tube shape with both ends closed, the connecting part 223 will compress the air inside it when it follows the stabilizing rod 222 to move to the rear side. At this time, the connecting part 223 will be difficult to move to the rear side. , the connecting part 223 and the fluid cannot form a hydraulic buffering effect, and for the completely closed liquid pipe 221, if the fluid moves in the liquid pipe 221 for a long time, the fluid will gradually form a dirty liquid, which is not conducive to discharge and replacement. The inner wall of the liquid tube 221 cannot be cleaned, which causes cleaning problems for medical instruments that need to meet cleanliness specifications. This embodiment makes further improvements based on Embodiment 1, as shown in Figure 6:

One side of the liquid tube 221 is open, and the open side of the liquid tube 221 is threadedly connected to a closing ring 224. The stabilizing rod 222 penetrates the inside of the closing ring 224 and faces outward, and an end surface of the liquid tube 221 close to the closing ring 224 is provided with Air chamber 2211. The air chamber 2211 is used to prevent the inside of the liquid tube 221 from being completely closed when the closing ring 224 is connected. When the connecting part 223 moves to the rear, the connecting part 223 will squeeze the air in the liquid tube 221 along the air chamber. 2211 is discharged, ensuring that the connection part 223 and the liquid can move normally rearward, and the maximum movement distance of the connection part 223 will not contact the air chamber 2211, preventing the discharge of the liquid ventilation chamber 2211 from forming a cyclic hydraulic buffering effect, and in the liquid pipe 221, After repeated use of the stabilizer rod 222 and the connecting part 223 with the fluid, the sealing ring 224 is unscrewed, the fluid is discharged and replaced, and the inner wall of the liquid pipe 221 and the surface of the connecting part 223 are cleaned to ensure the medical cleanliness of the stabilizer 220.

Example 4

In order to record the number of times the blood collection tube is shaken by the tube connection platform 120, so that the personnel can know how many times the pressure currently exerted by the hand will cause the blood collection tube to shake, and further ensure that the blood collection tube is positioned on the tube connection platform 120. The number of shaking is precisely limited. This embodiment is further improved on the basis of Embodiment 1, as shown in Figures 9 and 10:

A liquid display member 230 is provided below the stable member 220. The liquid display member 230 includes a carrier cavity plate 231 with a cavity inside. The top of one end of the carrier cavity plate 231 is connected to the liquid pipe 221 through a connecting cavity tube 232, and the communicating cavity is The tube 232 is located on the left side of the middle of the liquid tube 221, and the side of the carrier cavity plate 231 can be engraved with a liquid capacity mark, wherein the connecting cavity 232 is used to transfer a part of the liquid along the connecting cavity 232 when the fluid reaches the current position. It flows downward into the carrier cavity plate 231. The inner diameter of the communication cavity tube 232 is small, so that the fluid flows along the communication cavity tube 232 slowly, preventing the fluid from completely flowing into the carrier cavity plate 231 and preventing subsequent fluid buffering. , when the fluid moves along the liquid tube 221 for the first time, the local liquid enters the carrier cavity plate 231 along the connecting cavity tube 232, and the medical staff can determine the first entry of the fluid through the fluid volume mark located on the side of the carrier cavity plate 231. The capacity of the carrier cavity plate 231 is the first rocking motion at this time, and because the rocking motion gradually becomes stable, the subsequent back-and-forth movement of the liquid into the connecting cavity 232 will decrease accordingly, so that personnel can adjust the capacity of the carrier cavity plate 231 according to the movement of the fluid. When the fluid moves back and forth and the local fluid flows to the regular volume in the carrier cavity plate 231, the reduced capacity of each fluid can be obtained. Finally, when the tube connection platform 120 is balanced and the fluid no longer moves, according to the fluid volume in the carrier cavity plate 231 The volume data can be used to determine the specific number of shaking movements of the blood collection tube driven by the tube connection platform 120 under the pressure of the hand, which can facilitate the pressing force according to the number of times of uniform shaking of the blood collection tube (obtained step by step in the above) The measurement of fluid reduction and the shaking number based on the fluid volume finally located on the carrier chamber plate 231 can be obtained by conducting multiple experiments, thereby eliminating the need for medical staff to measure the fluid reduction data in real time when emergency shaking of the blood collection tube is required. more conducive to the current situation).

Considering that the local fluids received in the carrier cavity plate 231 are fluids that have been used multiple times in the cavity, in order to ensure that the carrier cavity plate 231 can be easily cleaned and has a certain degree of cleanliness, a closing plug is connected to the side of the carrier cavity plate 231 233, and an extension part 2331 is installed on the side of the closing plug 233. The end of the extension part 2331 is provided with a ring piece 2332. The ring piece 2332 is located at the inner edge of the carrier cavity plate 231. The closing plug 233 is threadedly connected to the carrier cavity plate 231. When The closing plug 233 is screwed out, and the fluid received by the carrier cavity plate 231 is discharged. When the closing plug 233 drives the extension part 2331 to move out, the ring piece 2332 scrapes the inner wall of the carrier cavity plate 231, so that when the fluid is quickly discharged, it also affects the carrier cavity plate 231. The inner wall is formed to scrape away dirt.

Example 5

Among them, for another situation in which the communicating cavity tube 232 communicates with the carrier cavity plate 231:

When the connecting portion 223 and the fluid move toward the rear side along the liquid tube 221 and the fluid moves closer to the communicating lumen 232 and does not contact the communicating lumen 232, and when the connecting portion 223 is located on the left side of the communicating lumen 232, the connecting portion 223 connects the carrier cavity The plate 231 forms a closed cavity structure. Due to the pressure, the movement of the connecting portion 223 will be blocked to a certain extent, thereby once again strengthening the buffering force of the connecting portion 223 and the fluid to cooperate with the movement, so that the movement range of the stabilizer 220 is reduced. , so that the buffering force of the smooth member 220 on the second elastic member 210 and the first elastic member 130 increases, so that the rocking motion of the tube connecting table 120 can quickly become stable, thereby enhancing the protection of blood cells in the blood collection tube. If necessary When the number of shaking is large, it is only necessary to exert greater force on the hand pressing platform 123 .

Example 6

Considering that insufficient flow of fluid in the chamber of the liquid pipe 221 to the carrier chamber plate 231 affects the buffering strength, this embodiment makes further improvements based on Embodiment 1, as shown in Figures 2 and 11:

A hollow liquid storage cavity plate 240 is provided above the liquid display part 230.
