Pericardial effusion, pleural effusion and spontaneous pneumothorax are common diseases in clinical medicine. In most cases, in order to confirm the diagnosis and treatment, pericardial effusion and pleural effusion must be punctured and drained.

In the prior art, a puncture needle is generally inserted into the pleural cavity, and then a drainage tube and a syringe are used to extract the effusion inside the pleural cavity. It is necessary to disassemble the syringe several times in order to discharge the effusion extracted from the syringe before the next pumping work. This operation method is not only troublesome, but also will delay a lot of time and seriously slow down the progress of pumping;

In addition, when the effusion is too much, the efficiency of using a conventional needle tube to extract the effusion is relatively low, which will affect the progress of the fluid extraction to a certain extent. For patients who urgently need to deal with pericardial effusion, it is easy to miss the best opportunity for treatment.

Sub-process:

The following is the working process of the pumping speed adjustment component:

When in use, the drainage tube used for puncture has been fixed and plugged in the corresponding position. Further, the medical staff adjust the pumping speed adjustment component according to the specific situation of the patient. After speeding up, the medical staff can move the position of the rack 213 meshing with it by twisting the gear 214. Since the rack 213 is fixedly connected with the L-shaped resistance liquid 212, the rack 213 is driven by the rotating gear 214 to move. , the L-shaped resistance liquid 212 will gradually unblock several first liquid inlet holes 215, that is, by unblocking the number of first liquid inlet holes 215, the amount of one needle tube drawn each time can be indirectly changed, or more than one needle can be drawn. The volume of the needle tube, this setting can effectively avoid the situation that when the effusion is too much, the pumping speed is slow and the best treatment opportunity is missed, and when the effusion is normal, the pumping speed is fast, causing discomfort to the patient;

Please refer to Figure 2 to Figure 5 for the above working process.

The following is the working process of the pull transfer assembly:

Furthermore, after the adjustment of the pumping speed adjustment assembly is completed, the medical staff will hold their hands in the grip opened on the push-pull rod 2211, and then pull the push-pull rod 2211 to make the connecting rod 2210 set on the push-pull rod 2211 move away from the main cavity 1 the outer wall moves in the direction of the outer wall. During this process, the guide rod 226 arranged on the connecting rod 2210 will make the groove plate 224 move upward with the plugging piece 223 fixedly connected with the assistance of the guide groove 225, and the blocking piece 223 During the upward movement, the second liquid inlet hole 222 previously blocked by the blocking sheet 223 will be gradually unblocked, and at the same time, since the push-pull rod 2211 is in the pulling state, the piston fixedly connected to the push-pull rod 2211 The sheet 2212 will follow the push-pull rod 2211 to move in the pumping chamber 221 at this time. During the movement of the piston sheet 2212, the effusion in the patient's body will enter the gap between the partition plate 211 and the inner wall of the main cavity 1 from the drainage tube. In the temporary storage space for the effusion composed of space, and enter into the liquid suction chamber 221 through the first liquid inlet hole 215 and the second liquid inlet hole 222, further, when the piston plate 2212 in the liquid suction chamber 221 is pulled When gradually moving to the tail of the suction chamber 221, the medical staff will push the push-pull rod 2211 to make the piston piece 2212 approach the direction of the blocking piece 223, and thus set the extracted effusion in the suction chamber 221 through the connection. The transfer tube 301 on the top is transferred;

In addition, when the medical personnel pull the push-pull rod 2211, the guide rod 226 indirectly connected with it will move into the horizontal groove at the bottom of the guide groove 225 and gradually move to the tail of the suction chamber 221 as the push-pull rod 2211 is pulled. When the guide rod 226 will gradually approach the position where the barrier block 229 is located, during the movement, the guide rod 226 will move the barrier block 229 downward under the action of the slope of the barrier block 229. At this time, the bottom surface of the barrier block 229 is located in the auxiliary chamber. The first spring 228 in the block 227 is compressed, and further, when the medical staff pushes the push-pull rod 2211 to make the piston piece 2212 approach the direction of the blocking piece 223, the guide rod 226 will be against the non-slope part of the blocking block 229, With reference to Fig. 7 and Fig. 8, the guide rod 226 at this time will move upward in the chute on the right side of the guide groove 225 within the restriction of the barrier block 229, and in the process, the guide rod 226 will be inclined on the right side of the guide groove 225. With the aid of the groove, the groove plate 224 is moved downwards, thereby indirectly causing the groove plate 224 to carry the sealing sheet 223 to block the second liquid inlet hole 222, so as to provide a working premise for the transfer of the extracted effusion;

Furthermore, since it is known that the guide groove 225 is a quadrilateral, the inclinations of the left and right sides are different. When the liquid accumulates, the guide rod 226 will cooperate with the inclined chute on the left side of the guide groove 225, so as to indirectly make the blocking piece 223 slowly unblock the second liquid inlet hole 222, so as to avoid the leakage when the liquid is just pumped. Due to the fast pumping speed, the effusion is quickly pumped out from the patient's body, causing discomfort to the patient. Further, the steeper setting on the right side can effectively push the push-pull rod 2211 to make the liquid in the pumping chamber 221 When the piston piece 2212 approaches the direction of the blocking piece 223, the blocking piece 223 is quickly blocked off the second liquid inlet hole 222, which is beneficial to the transfer of the extracted effusion in the pumping chamber 221, and prevents the extracted effusion from being drawn out again. pushed back into the patient;

Please refer to Figure 1 to Figure 3 and Figure 6 to Figure 8 for the above working process.

Furthermore, through the overall setting of the puncture and drainage mechanism, it is not necessary to disassemble the syringe barrel multiple times in the traditional way when extracting the effusion. It avoids the trouble of traditional operation methods to a large extent, saves a lot of time, makes an important contribution to the progress of pumping fluid, and is beneficial to the rescue work of patients;

The following is the working process of the effusion collection and treatment mechanism:

Furthermore, when the medical personnel pull the push-pull rod 2211 to extract the effusion in the patient's body, their hands will be held in the grip on the push-pull rod 2211. At this time, the contact A313 on the pressing piece 311 will contact with the contact B314. Contact, the second spring 312 is in a compressed state, the electromagnet 304 that is electrically connected to the contact A313 and the contact B314 will be energized to generate magnetism, further, the connecting rod 2210 fixedly connected to the push-pull rod 2211 will be in the process of pulling Move with the electromagnet 304 arranged on it, and in the movement of the electromagnet 304, the electromagnet 304 will be arranged on the magnet 307 on the translation piece 306 in the alcohol bin 302, and in the adsorption process, the translation piece 306 will be Approaching the electromagnet 304, the liquid outlet hole 303 opened on the bottom of the alcohol bin 302 blocked by the translation piece 306 will coincide with the auxiliary hole 308, and the alcohol in the alcohol bin 302 will enter the effusion collection chamber 309 at this time. Further, the electromagnet 304 will be assisted by pulling the transfer assembly, and the effusion will enter the effusion collection chamber 309 from the transfer tube 301. At this time, the effusion in the effusion collection chamber 309 will mix with alcohol, and When the medical staff pushes the push-pull rod 2211 to approach the blocking piece 223, the hand of the medical staff will release the pressure on the pressing piece 311. At this time, the electromagnet 304 is powered off, and the electric agitating rod 310 will be driven by the driving motor. The effusion in the collection chamber 309 is stirred with alcohol to initially disinfect the effusion with germs, that is, the setting of the effusion collection and treatment mechanism can avoid infection of the operator to the greatest extent during extraction and collection;

Furthermore, during the movement of the electromagnet 304, only the magnet 307 that was on the same straight line as the electromagnet 304 at that time will be attracted by the electromagnet 304, and the auxiliary hole 308 on the translation piece 306 will coincide with the liquid outlet hole 303, The alcohol in the alcohol chamber 302 will enter into the effusion collection chamber 309. This arrangement can only move the translation plate 306 corresponding to the moving electromagnet 304 when the medical staff pulls the push-pull rod 2211, and passes through the The assistance of the liquid outlet hole 303 and the auxiliary hole 308 injects alcohol into the fluid collection chamber 309, thereby saving alcohol resources.

Please refer to Figure 1 to Figure 3 and Figure 9 to Figure 11 for the above working process.

Overview:

When in use, according to the specific conditions of the patient, the pumping volume can be changed by adjusting the liquid pumping speed assembly each time, that is, by removing the blocking quantity of the first liquid inlet hole 215, one pumping volume can be indirectly changed each time. The amount of the needle tube is still the amount of pumping multiple needle tubes. This setting can effectively avoid the slow pumping speed and miss the best treatment opportunity when the effusion is too much, and the fast liquid pumping speed when the effusion is normal, resulting in If the patient is uncomfortable, further, the effusion can be extracted and transferred continuously without dismantling the syringe through the setting of the pulling transfer assembly. In addition, when the pulling transfer assembly is working, the electromagnetism set on the connecting rod 2210 can Under the indirect action of iron 304 and magnet 307 in the alcohol bin 302, the alcohol in the alcohol bin 302 can be transferred to the effusion collection chamber 309, and mixed with the extracted and transferred effusion. The effusion with germs should be treated with preliminary sterilization and disinfection.
