Description

Electric abdominal cavity drainage device

Technical Field

The utility model belongs to the technical field of drainage devices, and particularly relates to an electric abdominal cavity drainage device.

Background

Abdominal drainage is a common clinical treatment method and is mainly used for treating diseases such as peritoneal effusion. Peritoneal effusion is a common clinical condition that may be caused by a variety of causes, such as infection, inflammation, tumors, or postoperative complications. Such effusion may lead to pain, discomfort, spread of infection and even organ dysfunction. Therefore, it is important to drain the peritoneal fluid efficiently at all times. There are two main types of peritoneal drainage devices currently used in hospitals: (1) disposable reservoir bag drainage system: such systems typically consist of a drain tube and a disposable reservoir bag. One end of the drainage tube is inserted into the abdominal cavity of the patient, and the other end is connected to the liquid storage bag. Since the reservoir bag is generally above the drain tube, liquid is introduced into the reservoir bag by gravity and the pressure differential between the inside and outside of the bag. The drainage mode is simple and easy to use, but the drainage efficiency is low, and the drainage speed cannot be adjusted. (2) negative pressure ball drainage system: such systems typically consist of a drain tube, a negative pressure bulb and a reservoir bag. The negative pressure ball generates negative pressure through manual extrusion, and aspirates effusion in the abdominal cavity. The effusion flows into the negative pressure ball through the drainage tube and is pushed into the liquid storage bag. The method needs to manually squeeze the negative pressure ball at regular intervals, has large workload and cannot continuously and stably drain.

The two devices meet the requirements of peritoneal drainage to a certain extent, but have obvious defects in drainage efficiency, operation convenience, drainage speed adjustment and the like.

In order to solve the problems, the utility model provides an electric abdominal cavity drainage device.

Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the present application. The appearances of such phrases in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. Those of skill in the art will explicitly and implicitly appreciate that the embodiments described herein may be combined with other embodiments.

As shown in fig. 1 to 5, an electric abdominal drainage device of an exemplary embodiment includes a liquid storage tank 1, an aspirator 2, and a drainage tube 3; the input end of the aspirator 2 is connected with the drainage tube 3, and the output end of the aspirator 2 is connected with the liquid storage tank 1; the aspirator 2 sucks the accumulated liquid in the abdominal cavity of the patient into the aspirator through the drainage tube 3 and then conveys the accumulated liquid into the liquid storage tank 1; further, the aspirator 2 includes a motor 21, an outer casing 22, a rotor 23, a cover 24, and a hose 25; the outer shell 22 and the motor 21 are respectively fixedly mounted on the upper surface of the liquid storage tank 1, an output end 211 of the motor 21 extends into the outer shell 22 and is connected with the rotor 23, a hose 25 spirals in the outer shell 22 and surrounds the rotor 23, one end of the hose 25 is connected with the drainage tube 3, the other end of the hose 25 extends into the liquid storage tank 1, and the sealing cover 24 is connected with the outer shell 22. The aspirator 2 specifically includes a motor 21, an outer casing 22, a rotor 23, a cover 24, and a hose 25. The outer housing 22 and the motor 21 are fixedly mounted on the upper surface of the tank 1. The output 211 of the motor 21 extends into the interior of the outer housing 22 and is connected to the rotor 23. A hose 25 is wound inside the outer housing 22 and surrounds the rotor 23. One end of the hose 25 is connected with the drainage tube 3, and the other end extends into the liquid storage tank 1. A cover 24 is coupled to the outer housing 22 to protect the internal structure.

In use, one end of the drainage tube 3 is inserted into the abdominal cavity of a patient and secured. The motor 21 is then started. The output of the motor 21 drives the rotor 23 in rotation, which rotor 23 during rotation squeezes the hose 25 to push the liquid flow. Specifically, the rotor 23 periodically compresses the hose 25 when rotated, so that the liquid in the hose 25 is pressed by the wall of the compressed pipe, and a reaction force is generated to push the liquid in the pipe direction. When the rotor 23 is pressed through the hose 25, the wall of the tube, which has just been compressed, will return to its original shape, thereby drawing in new liquid. This process is repeated so that the liquid is continuously delivered. The liquid enters the liquid storage tank 1 through the hose 25, so that electric drainage of the abdominal cavity of the patient is realized.

It should be noted that the specific rotation direction of the rotor 23 should be set according to actual needs. Taking fig. 3 as an example, the rotation direction of the rotor 23 should be counterclockwise along the axis of the output end of the motor 21 when sucking and transporting the liquid.

The insertion procedure of the drainage tube 3 should be operated by a medical professional in a strictly sterile environment. First, the physician will disinfect the abdomen of the patient and then puncture the abdomen at the appropriate location to insert the drain. The specific insertion location depends on the patient's condition and the location of the fluid accumulation, and common insertion locations include the groin, around the navel, or other suitable locations in the abdominal cavity.

One end of the drainage tube 3 is inserted into the abdominal cavity of the patient, and the other end is connected to the aspirator 2. When the motor 21 is started, the rotor 23 starts to rotate, and the liquid in the abdominal cavity is sucked and delivered into the liquid storage tank 1 by periodically compressing and releasing the hose 25.

The main reasons for the application of the utility model to abdominal drainage are as follows: peritoneal effusion is a common clinical condition that may be caused by a variety of causes, such as infection, inflammation, tumors, or postoperative complications. Such effusion may lead to pain, discomfort, spread of infection and even organ dysfunction. Therefore, it is important to drain the peritoneal fluid efficiently at all times. The electric abdominal cavity drainage device can provide a simple, efficient and safe drainage method, is beneficial to improving symptoms of patients, reducing risks of complications and improving life quality of the patients.

It is emphasized that the present utility model is unique in the design of the rotor 23, and the rotor 23 is driven by the motor 21 to periodically compress and loosen the hose 25, thereby achieving the suction and discharge of the liquid. The design ensures that the device has higher efficiency and stability in the working process.

In addition, the design of the aspirator 2 of the utility model considers the usability and the safety, the input end of the aspirator 2 is connected with the drainage tube 3, and the output end is connected with the liquid storage tank 1, thereby ensuring that the liquid can be effectively sucked and stored in the drainage process. Meanwhile, the cover 24 of the aspirator 2 is designed to protect the motor 21, the outer casing 22 and the rotor 23 inside, thereby improving the durability of the device.

In conclusion, the electric abdominal cavity drainage device provided by the utility model provides a high-efficiency, reliable, safe and easy-to-use solution, and can meet the requirements of the medical industry on abdominal cavity drainage.

In the use process, when the electric peritoneal drainage device is used, the flow rate of the fluid in the hose 25 can be adjusted by adjusting the rotation speed of the motor 21. The rotational speed of the motor 21 directly affects the frequency of the squeezing of the hose 25 by the rotor 23 and thus the fluid delivery rate. By precisely controlling the rotational speed of the motor 21, we can adjust the drainage speed of the liquid according to the specific needs of the patient, thereby ensuring the comfort of the patient and preventing potential problems due to too fast drainage speed. This functionality enhances the flexibility and applicability of the present utility model, enabling it to meet the needs of different patients and different conditions.

The rotational speed adjustment of the motor is mainly dependent on changing the supply voltage or current of the motor or changing the settings of the electronic controller of the motor. The rotation speed adjusting principle of the motor is mainly based on the working principle of the motor. The rotation speed of the motor is determined by the voltage and the current of the power supply, and the rotation speed of the motor can be changed by changing the voltage or the current of the power supply. More complex electronic controllers can achieve accurate control of motor speed by accurately controlling supply voltage and frequency. The following is the current common motor speed adjustment method:

adjusting a power supply voltage: this is the simplest method, applicable to a dc motor. By varying the supply voltage, the rotational speed of the motor can be varied. The higher the voltage, the faster the motor speed; conversely, the lower the voltage, the slower the rotational speed of the motor.

Adjusting the power supply frequency: this method is mainly applicable to ac motors. By varying the power supply frequency, the rotational speed of the motor can be varied. The higher the frequency, the faster the rotational speed of the motor; conversely, the lower the frequency, the slower the rotational speed of the motor.

In another embodiment of the utility model, the outer housing 22 and the cover 24 are connected by screws, while the motor 21 is fixedly connected to the upper surface of the tank 1 by a fixing frame 26. Specifically, the cover 24 has predetermined holes through which screws pass and connect with threaded holes in the outer housing 22, thereby securing the cover 24 to the outer housing 22. The practicality of this kind of structural design is strong, is convenient for maintain and overhaul. If the parts inside the outer shell 22 need to be overhauled or lubricated, the cover 24 is only required to be disassembled. During use of the aspirator 2, due to a certain friction between the rotor 23 and the hose 25, a certain wear may be caused to the hose 25 or the rotor 23. This design thus also allows the user to easily inspect and replace the rotor 23 and hose 25, thereby extending the service life of the device and ensuring the effectiveness and safety of its operation. If replacement of these components is required, only the cover 24 is removed and a corresponding service or replacement operation is performed.

In another embodiment of the present utility model, in a preferred embodiment of the present utility model, the rotor 23 includes an inner housing 231, a gear 232, a rack 233, a mount 234, and a roller 235. The inner housing 231 is disposed inside the outer housing 22 and connected to the output end of the motor 21. The gear 232 is rotatably mounted inside the outer housing 22, and the rack 233 is engaged with the gear 232. An opening is provided in a side wall of the inner housing 231, and a mounting seat 234 is slidably mounted in the opening and fixedly coupled to the rack 233. The roller 235 is rotatably mounted to the mount 234. Referring to fig. 2 to 5, the number of racks 233, the mounting seats 234 and the rollers 235 is three.

The rotor 23 also includes a drive assembly 236 that includes a housing 2361, two sets of springs 2362, two latches 2363, and two dials 2364. The two pulling pieces 2364 are fixedly connected with the two locking pieces 2363, respectively. Two sliding grooves 2365 are formed in the box body 2361, and a spring mounting seat 2366 is arranged in the box body 2361. Two sets of springs 2362 are mounted on spring mounts 2366, respectively. The locking member 2363 is disposed inside the case 2361 and slidably connected to the case 2361, and the paddle 2364 extends from the chute 2365. The surface of the inner housing 231 is provided with a locking groove 237, wherein the locking groove 237 and the locking piece 2363 are provided with a latch.

In a normal state, the two sets of springs 2362 respectively provide elastic forces for the two locking pieces 2363 to be separated from each other, and the pulling piece 2364 contacts with the edge of the sliding groove 2365 to play a limiting role on the two locking pieces 2363. At this time, the latch on the locking piece 2363 is engaged with the latch on the locking groove 237, and the locking piece 2363 is fixed. By connecting the locking member 2363 with the inner housing 231, the inner housing 231 can be rotated by rotating the locking member 2363.

In a specific implementation process, the cover 24 is first opened, and then the pulling piece 2364 is pinched to make the two pulling pieces 2364 approach each other, so that the two locking pieces 2363 approach each other, and the engagement connection between the locking pieces 2363 and the latch teeth on the locking groove 237 is cancelled. And then the driving assembly 236 is rotated, the driving gear 232 is rotated, the rotation of the gear 232 drives the rack 233 to move, and the rack 233 drives the mounting seat 234 to extend or retract the inner housing 231, so that the position of the roller 235 is adjusted.

By changing the position of the roller 235 during rotation of the rotor 23, the diameter of the circumferential track during rotation of the rotor 23 can be changed. More specifically, if the diameter becomes the maximum diameter of the circumferential track during rotation of the rotor 23, the degree of compression of the hose 25 is the highest, and at this time, the delivery amount of the liquid is also relatively large. In contrast, if the diameter becomes the minimum diameter of the circumferential track during rotation of the rotor 23, the degree of compression of the hose 25 is minimized, and at this time, the delivery amount of the liquid is also relatively small.

In the present embodiment, a limiting portion (not shown) for preventing the rack 233 from falling off is provided at an end of the rack 233 away from the mounting seat 234, for preventing the rack 233 from falling off from the inner housing 231. Although the flow rate of the liquid can be changed by adjusting the rotation speed of the motor 21 in the present embodiment, this adjustment is more dependent on the control of the circuit, and in contrast, the adjustment of the mechanical transmission structure has a certain advantage in reliability. Thus, the present embodiment provides a structure having higher reliability in flow adjustment.

More specifically, when the inner housing 231 rotates, the roller 235 rolls along the axis of the hose 25, compressing the hose 25. At this time, the liquid in the hose 25 is pressed by the wall of the compressed pipe, and a reaction force is generated, so that the liquid is pushed in the pipe direction. When the roller 235 rolls over the hose 25, the wall of the tube just compressed will return to its original shape, thereby drawing in new liquid, and so on, and realizing continuous delivery of the liquid. Notably, the roller 235 also rotates itself when in contact with the hose 25, which is designed to effectively reduce friction against the hose 25, thereby extending the useful life of the hose.

In another embodiment of the utility model, the liquid storage tank 1 is composed of an inner tank 11, an outer tank 12 and a cover 13. The inner case 11 is disposed inside the outer case 12, and a strip-shaped notch 14 is formed in the outer case 12. The inner box 11 is a transparent box, and is provided with scale marks 15, wherein the scale marks 15 correspond to the strip-shaped notches 14 of the outer box 12.

More specifically, the healthcare worker can directly view the amount of liquid in the inner housing 11 by looking at the bar-shaped notch 14 on the outer housing 12. The provision of the graduation marks 15 enables the medical staff to accurately observe and measure the amount of liquid in the inner tank 11. In addition, the graduation marks 15 are marked with corresponding volume values, and medical staff can accurately know the specific liquid amount discharged from the abdominal cavity of the patient by checking the values.

The design enables medical staff to monitor the drainage condition of a patient in real time and accurately, is beneficial to evaluating the curative effect and adjusting the treatment scheme, and provides more careful care for the patient.

In another example of the present utility model, the cover 13 and the inner case 11 are fastened together. When the inner box 11 needs to be cleaned, only the cover 13 needs to be removed, the accumulated liquid in the inner box 11 is poured out, and then the inner wall of the inner box 11 is flushed by clean water. Next, sterilization treatment may be performed by injecting boiling water into the inside of the inner tank 11, sterilizing at high temperature, or directly injecting a sterilizing liquid into the inside of the inner tank 11. The disinfectant may be medical alcohol or other disinfectant.

In addition, the outer case 12 is made of rubber, which provides good friction when held by a medical staff, preventing the liquid storage tank 1 from slipping off the hand of the medical staff. This is because rubber is a material with good damping and grip, and its surface microstructure can create some friction with human skin, thereby increasing grip stability and reducing the likelihood of slipping. The design is more humanized, and the safety and convenience of medical staff in operation are improved.

In another example of the utility model, the electric peritoneal drainage device further comprises a fluid level alarm 4. The main function of the liquid level alarm is to monitor the liquid level in the liquid storage tank 1. When the liquid in the liquid storage tank 1 is nearly fully loaded, the liquid level alarm can give an alarm so as to remind medical staff of cleaning the liquid in the liquid storage tank 1 at any time.

The level alarm 4 comprises a speaker 41, a touch switch 42 and a switch trigger assembly 43. Wherein the speaker 41 and the contact switch 42 are both provided on the cover 13. The speaker 41 may be an existing small moving coil speaker or a piezoelectric speaker, which mainly functions to sound an alarm. The contact switch 42 is provided on the lower surface of the cover 13, and may be a conventional micro switch or a capacitive touch switch.

The operation principle of the contact switch 42 is based on the switching of the current. When the contact switch 42 touches something (in this case the switch trigger assembly 43) the switch will close and the circuit will be closed, whereupon the speaker 41 will sound. Conversely, when the contact switch 42 no longer contacts the switch trigger assembly 43, the switch will open, the circuit will open, and the speaker 41 will no longer sound.

The main function of the switch triggering assembly 43 is to trigger the contact switch 42 when the liquid in the liquid storage tank 1 reaches a certain height. Specifically, when the height of the liquid rises to the position of the trigger assembly 43, the buoyancy of the liquid will raise the trigger assembly 43, and the trigger assembly 43 will contact the contact switch 42 after being raised, so as to trigger the switch and make the speaker 41 make a sound. Thus, medical staff can be reminded, and the liquid in the liquid storage tank 1 is close to full load, so that the liquid storage tank needs to be cleaned in time.

In another example of the present utility model, switch activating assembly 43 includes a tube 431, a float bladder 432, and a feeler lever 433. An upper limit part 434 and a lower limit part 435 are provided on the inner wall of the tube 431, and the floating capsule 432 is provided inside the tube 431. The floating bag 432 can float up and down in the pipe body 431 by the floating force of the liquid in the liquid storage tank 1. The feeler lever 433 is mounted on the upper portion of the floating bag 432, and the pipe body 431 is fixedly mounted in the liquid storage tank 1 near the upper portion of the liquid storage tank 1.

The flotation bladder 432 and trolley 433 are typically made of a lightweight material, such as plastic, that is capable of floating in a liquid. The feeler lever 433 is provided to be able to push the contact switch 42.

Specifically, as the liquid in the tank 1 gradually increases, the liquid level starts to rise. When the liquid level in the liquid storage tank 1 rises to the inlet pipe 431, the floating bag 432 will float along with the liquid level under the buoyancy of the liquid, and this will drive the feeler lever 433 to move upwards inside the pipe 431. When the upper end of the feeler 433 contacts the contact switch 42, the contact switch 42 is triggered to turn on the speaker 41, and make a sound. Thus, medical staff can be reminded, and the liquid in the liquid storage tank 1 is close to full load, so that the liquid storage tank needs to be cleaned in time.
