[0002] The chest and abdominal drainage device used in thoracic and cardiovascular surgery is a medical device used for clinical surgical drainage. It can guide the pus, blood and liquid accumulated in the human body tissue or body cavity to the outside of the body to prevent postoperative infection and promote wound healing. There are many types of surgical drainage tubes used in clinical practice, some are used for urinary catheterization, some are used for wounds, and they are used in the chest cavity, brain cavity, gastrointestinal tract and bile duct.

[0003] Existing thoracic and abdominal drains for cardiovascular surgery still have some defects. Most of them rely on manual compression of the airbag to allow negative pressure to suck out the accumulated fluid in the body cavity, which increases the workload of medical staff. The use of mechanical devices cannot control the pressing force and speed very well, making the mechanical pressing method relatively formatted. Different pressing machines need to be replaced according to the actual situation of the patient, which puts a heavy burden on the hospital. Summary of the invention

The end of the pressure detector 222 away from the airbag 205 is fixedly connected to the drainage tube 1, and a fixing ring 208 is arranged outside the placement groove 206. There are three fixing rings 208 and they are fixedly connected to the chassis 201. The fixing rings 208 correspond to the limit block 1 207.

[0034] Preferably, a threaded rod 203 is rotatably connected at the center of the fixed ring 208, and the end of the threaded rod 203 away from the chassis 201 is fixedly connected to the top plate 202. A movable ring 211 is threadedly connected on the threaded rod 203, and the movable ring 211 is located between the upper pressure plate 204 and the placement groove 206.

A locking block 212 is fixedly connected to the end of the movable ring 211 close to the upper pressure plate 204, and the locking block 212 is slidably connected to the limit rod 210.

[0035] Preferably, the end of the electric telescopic rod 214 away from the opening 213 is fixedly connected to a pressure block 215, the outer side of the pressure block 215 is fixedly connected to a connecting block 216, there are three connecting blocks 216, each connecting block 216 is located between adjacent threaded rods 203, the end of the connecting block 216 away from the chassis 201 is fixedly connected to a trigger block 218, the end of the connecting block 216 away from the trigger block 218 is fixedly connected to a connecting block 217, and the end of the connecting block 217 close to the chassis 201 is fixedly connected to a trigger block 219.

[0036] Specifically, before starting the device, it is necessary to control the rotation of the threaded rod 203 according to the actual situation of the patient, and all the threaded rods 203 rotate synchronously. While the threaded rods 203 rotate, the limit rod 210 limits the rotation of the moving ring 211, so that the moving ring 211 can move up and down. When the moving ring 211 moves to the corresponding position, the threaded rod 203 is controlled to stop rotating so that the moving ring 211 can stay at this time, and the device is started.

When the pressing block 215 moves downward, it will generate a pressure on the upper pressure plate 204, so that the airbag 205 is in a compressed state. When the pressing block 215 moves upward, the pressure of the pressing block 215 on the upper pressure plate 204 disappears, so that the upper pressure plate 204 is in a compressed state under the action of the air pressure. The airbag 205 is restored to its original state, thereby generating negative pressure in the airbag 205, and the negative pressure flows to the drainage tube 1 through the opening 213, and then flows to the drainage bag 5 through the drainage tube 1, so that the debris on the patient can flow to the drainage bag 5 through the drainage tube 26, thereby completing a treatment for the patient. At the same time, during the operation of the entire device, the connecting tube 221 will monitor the pressure at the pressure detector 222.

[0039] Specifically, by rotating the knob 307, the knob 307 rotates to drive the gear 2 303 to rotate, the gear 2 303 rotates to rotate the gear 1 302, and then the connecting disk 301 rotates, the connecting disk 301 rotates to drive the working box 2 to rotate, so that the working box 2 can be installed in multiple directions.

[0040] See also Figure 7 and Figure 8 The lifting frame 4 includes a threaded column 401 that is threadedly connected to the rotating disk 3.

[0043] Specifically, before use, the medical staff will first open the clamping block 411 so that the clamping block 411 no longer restricts the telescopic tube 408, the telescopic tube 407 and the telescopic tube 404, and then control the telescopic tube 404, the telescopic tube 407 and the telescopic tube 408 to be extended to the corresponding height so that the installation position of the device can meet the needs. When the telescopic tube 404, the telescopic tube 407 and the telescopic tube 408 are extended to the corresponding length, the clamping block 411 will be bent so that the telescopic tube 404, the telescopic tube 407 and the telescopic tube 408 will not change in length. When the limit piece 413 moves, it will synchronously drive the connecting rod 410 to rotate, and then drive the connecting ring 412 to slide on the connecting column 405 until the connecting ring 412 is engaged with the connecting column 405, and the connecting rod 410 is in a horizontal state.

[0044] Working principle of the present invention: before use, medical personnel first break open the clamping block 411 so that the clamping block 411 no longer restricts the telescopic tube 2 408, the telescopic tube 1 407 and the telescopic tube 404, and then control the telescopic tube 404, the telescopic tube 1 407 and the telescopic tube 2 408 to be extended to the corresponding height so that the installation position of the device can meet the requirements; when the telescopic tube 404, the telescopic tube 1 407 and the telescopic tube 2 408 are extended to the corresponding length, the clamping block 411 is broken so that the telescopic tube 404, the telescopic tube 1 407 and the telescopic tube 2 408 no longer change in length; while the limiter 1 413 moves, the connecting rod 410 is synchronously driven to rotate, and then the connecting ring 412 is driven to slide on the connecting column 1 405, until Until the connecting ring 412 is engaged with the connecting column 1 405, at this time the connecting rod 410 is in a horizontal state, and then the working box 2 is threadedly connected with the threaded column 1 304 at the upper end of the connecting disk 1 305 through the threaded groove 1 220 at the lower end of the chassis 201, so that the working box 2 and the rotating disk 3 are relatively fixed, and then the threaded groove 2 306 at the lower end of the rotating disk 3 is threadedly connected with the threaded column 2 401, so that the device is fixed as a whole, and finally, by turning the knob 307, the knob 307 rotates to drive the gear 2 303 to rotate, and the gear 2 303 rotates to rotate the gear 1 302, thereby rotating the connecting disk 301, and the connecting disk 301 rotates to drive the working box 2 to rotate, so that the working box 2 can be installed in various directions, and at the same time, medical personnel The staff hangs the drainage bag 5 on the hook 406, and connects the drainage tube 26 and the drainage tube 1 to the drainage bag 5, connects the other end of the drainage tube 1 to the opening 213 on the working box 2, and places the other end of the drainage tube 26 at the corresponding position of the patient. Before starting the device, it is necessary to control the rotation of the threaded rod 203 according to the actual situation of the patient. All threaded rods 203 rotate synchronously. While the threaded rod 203 rotates, the limit rod 210 limits the rotation of the moving ring 211, so that the moving ring 211 can move up and down. When the moving ring 211 moves to the corresponding position, the threaded rod 203 is controlled to stop rotating so that the moving ring 211 can stay at this time, and the device is started. The electric telescopic rod 214 drives the pressing block 215 to move downward. The pressing block 215 moves downward, driving the connecting block 1 216 to move downward. The connecting block 1 216 moves downward, driving the connecting block 2 217 to move downward synchronously. When the trigger block 219 at the lower end of the connecting block 217 contacts the moving ring 211, the trigger block 219 will be in a pressing state. At this time, the trigger block 219 controls the electric telescopic rod 214 to move in the opposite direction, that is, to move upward. The electric telescopic rod 214 moves upward, causing the pressing block 215 to move up and down synchronously, thereby driving the connecting block 1 216 to move upward synchronously. When the trigger block 1 218 at the upper end of the connecting block 1 216 contacts the top plate 202, the trigger block 1 218 is in a pressing state. At this time, the trigger block 1 218 controls the electric telescopic rod 214 to move in the opposite direction, that is, to move downward.As a result, the electric telescopic rod 214 continuously drives the pressing block 215 to reciprocate up and down. When the pressing block 215 moves downward, it will generate a pressure on the upper pressing plate 204, so that the airbag 205 is in a compressed state. When the pressing block 215 moves upward, the pressure of the pressing block 215 on the upper pressing plate 204 disappears, so that the upper pressing plate 204 returns to its original state under the action of air pressure, thereby generating negative pressure in the airbag 205. The negative pressure flows to the drainage tube 1 through the pressure detector 222, and then flows to the drainage bag 5 through the drainage tube 1 through the drainage tube 1, so that the debris on the patient can flow to the drainage bag 5 through the drainage tube 26, completing a treatment of the patient. At the same time, during the operation of the entire device, the connecting tube 221 will monitor the pressure at the pressure detector 222. When the monitored pressure changes abnormally, the connecting tube 221 will control the alarm to sound an alarm, thereby reminding medical personnel to check.
