Description

An electric abdominal drainage device

Technical field

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

Background technique

Abdominal drainage is a common clinical treatment method, mainly used to treat diseases such as abdominal effusion. Ascites is a common clinical condition that may be caused by a variety of causes, such as infection, inflammation, tumors, or postoperative complications. This accumulation of fluid can cause pain, discomfort, spread of infection, and even organ dysfunction. Therefore, timely and effective drainage of abdominal fluid is very important. There are two main types of abdominal drainage devices currently used in hospitals: (1) Disposable fluid storage bag drainage system: This system usually consists of a drainage tube and a disposable fluid storage bag. One end of the drainage tube is inserted into the patient's abdominal cavity, and the other end is connected to the fluid storage bag. Since the fluid storage bag is usually above the drainage tube, the accumulated fluid is introduced into the fluid storage bag using gravity and the pressure difference between the inside and outside of the bag. This drainage method 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: This system usually consists of a drainage tube, a negative pressure ball and a fluid storage bag. The negative pressure ball is manually squeezed to generate negative pressure and aspirate the fluid in the abdominal cavity. The accumulated fluid flows into the negative pressure bulb through the drainage tube and is then pushed into the fluid storage bag. This method requires regular manual squeezing of the negative pressure ball, which requires a large workload and cannot provide sustained and stable drainage.

These two devices meet the needs of abdominal drainage to a certain extent, but there are some obvious shortcomings in terms of drainage efficiency, ease of operation, and drainage speed adjustment.

In order to solve the above problems, the present utility model proposes an electric abdominal drainage device.

Reference herein to "an embodiment" means that a particular feature, structure or characteristic described in connection with the embodiment can be included in at least one embodiment of the present application. The appearances of this phrase 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 skilled in the art understand, both explicitly and implicitly, that the embodiments described herein may be combined with other embodiments.

As shown in Figures 1 to 5, an electric abdominal drainage device in an exemplary embodiment includes a liquid storage tank 1, an aspirator 2 and a drainage tube 3; the input end of the aspirator 2 and the drainage tube 3 connection, the output end of the aspirator 2 is connected to the liquid storage tank 1; the aspirator 2 inhales the fluid in the patient's abdominal cavity through the drainage tube 3, and then transports it to the liquid storage tank 1 in; furthermore, the suction device 2 includes a motor 21, an outer shell 22, a rotor 23, a cover 24 and a hose 25; the outer shell 22 and the motor 21 are respectively fixedly installed on the upper surface of the liquid storage tank 1, The output end 211 of the motor 21 extends into the interior of the outer casing 22 and is connected to the rotor 23. The hose 25 is coiled inside the outer casing 22 and surrounds the rotor 23. One end of the tube 25 is connected to the drainage tube 3 , the other end of the hose 25 extends into the inside of the liquid storage tank 1 , and the cover 24 is connected to the outer shell 22 . The suction device 2 specifically includes a motor 21, an outer shell 22, a rotor 23, a cover 24 and a hose 25. The outer shell 22 and the motor 21 are fixedly installed on the upper surface of the liquid storage tank 1 . The output end 211 of the motor 21 extends into the outer housing 22 and is connected with the rotor 23 . The hose 25 is wound inside the outer housing 22 and around the rotor 23 . One end of the hose 25 is connected to the drainage pipe 3 , and the other end extends into the inside of the liquid storage tank 1 . The cover 24 is connected to the outer shell 22 to protect the internal structure.

When in use, one end of the drainage tube 3 is inserted into the patient's abdominal cavity and fixed. Then start the motor 21. The output end of the motor 21 drives the rotor 23 to rotate, and the rotor 23 squeezes the hose 25 during the rotation to promote the flow of liquid. Specifically, when the rotor 23 rotates, it will periodically compress the hose 25. In this way, the liquid in the hose 25 will be squeezed by the compressed pipe wall, generating a reaction force to push the liquid along the pipe direction. When the rotor 23 presses through the hose 25, the newly compressed tube wall will return to its original shape, thereby sucking in new liquid. Repeat this process so that liquid continues to be delivered. The liquid enters the liquid storage tank 1 through the hose 25 to realize electric drainage of the patient's abdominal cavity.

It is worth noting that the specific rotation direction of the rotor 23 should be set according to actual needs. Taking Figure 3 as an example, when liquid is pumped and transported, the rotation direction of the rotor 23 should be counterclockwise along the output axis of the motor 21.

The insertion process of the drainage tube 3 should be performed by medical professionals in a strictly aseptic environment. First, the doctor will sterilize the patient's abdomen and then make a puncture at the appropriate location to insert the drainage tube. The specific insertion location depends on the patient's condition and the location of the fluid accumulation. Common insertion locations include the groin, around the navel, or other suitable places in the abdominal cavity.

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

The main reason why this utility model is suitable for abdominal drainage is that ascites is a common clinical disease, which may be caused by many reasons, such as infection, inflammation, tumor or postoperative complications. This accumulation of fluid can cause pain, discomfort, spread of infection, and even organ dysfunction. Therefore, timely and effective drainage of abdominal fluid is very important. The electric abdominal drainage device of the utility model can provide a simple, efficient and safe drainage method, which helps to improve the patient's symptoms, reduce the risk of complications and improve the patient's quality of life.

It is worth emphasizing that the utility model is unique in the design of the rotor 23. Driven by the motor 21, the rotor 23 periodically compresses and loosens the hose 25, thereby realizing the suction and discharge of liquid. This design makes the device more efficient and stable during work.

In addition, the aspirator 2 of the present invention is designed with ease of use and safety in mind. The input end of the aspirator 2 is connected to the drainage tube 3, and the output end is connected to the liquid storage tank 1, ensuring that the liquid is Can be inhaled and stored efficiently. At the same time, the cover 24 of the suction device 2 is designed to protect the internal motor 21, outer shell 22 and rotor 23, thereby improving the durability of the device.

In summary, the electric abdominal drainage device of the present invention provides an efficient, reliable, safe and easy-to-use solution that can meet the needs of the medical industry for abdominal drainage.

It should be noted that during use, when using the electric abdominal drainage device, 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 squeezing frequency of the hose 25 by the rotor 23, thereby affecting the delivery speed of the fluid. By precisely controlling the rotational speed of the motor 21, we are able to adjust the drainage speed of the fluid according to the specific needs of the patient, thereby ensuring patient comfort and preventing potential problems caused by too fast a drainage speed. This function enhances the flexibility and applicability of the present invention, allowing it to meet the needs of different patients and different conditions.

The speed adjustment of the motor mainly relies on changing the power supply voltage or current of the motor, or changing the settings of the motor's electronic controller. The principle of motor speed adjustment is mainly based on the working principle of the motor. The speed of the motor is determined by the power supply voltage and current. Changing the voltage or current of the power supply can change the speed of the motor. More complex electronic controllers can achieve precise control of motor speed by precisely controlling supply voltage and frequency. The following are the existing common motor speed adjustment methods:

Regulating the supply voltage: This is the simplest method and works for DC motors. By changing the supply voltage, the speed of the motor can be changed. The higher the voltage, the faster the motor rotates; conversely, the lower the voltage, the slower the motor rotates.

Adjust the power frequency: This method is mainly suitable for AC motors. By changing the power frequency, the speed of the motor can be changed. The higher the frequency, the faster the motor rotates; conversely, the lower the frequency, the slower the motor rotates.

In another embodiment of the present invention, the outer shell 22 and the cover 24 are connected through screws, and the motor 21 is fixedly connected to the upper surface of the liquid storage tank 1 through the fixing bracket 26 . Specifically, the cover 24 has preset holes, and screws pass through these holes and are connected to the threaded holes on the outer shell 22 , thereby achieving the fixation of the cover 24 and the outer shell 22 . This structural design is highly practical and easy to maintain and repair. If it is necessary to inspect or apply lubricating oil to the components inside the outer shell 22, it is only necessary to remove the cover 24. During use of the suction device 2, due to certain friction between the rotor 23 and the hose 25, certain wear may be caused to the hose 25 or the rotor 23. Therefore, this design also allows the user to easily inspect and replace the rotor 23 and hose 25, thus extending the service life of the equipment and ensuring the effectiveness and safety of its operation. If these parts need to be replaced, just remove the cover 24 and then perform corresponding maintenance or replacement operations.

In another embodiment of the present invention, in a preferred embodiment of the present invention, the rotor 23 includes an inner housing 231, a gear 232, a rack 233, a mounting base 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 meshes with the gear 232 . An opening is provided on the side wall of the inner housing 231 , and the mounting base 234 is slidably installed in the opening and is fixedly connected to the rack 233 . The roller 235 is rotatably mounted on the mounting base 234 . Please refer to Figures 2 to 5. The number of racks 233, mounting seats 234 and rollers 235 is three.

The rotor 23 also includes a driving assembly 236, which includes a box body 2361, two sets of springs 2362, two locking parts 2363 and two paddles 2364. The two paddles 2364 are fixedly connected to the two locking parts 2363 respectively. The box body 2361 is provided with two slide grooves 2365, and a spring mounting seat 2366 is provided inside the box body 2361. Two sets of springs 2362 are respectively installed on the spring mounting seats 2366. The locking member 2363 is disposed inside the box body 2361 and is slidingly connected to the box body 2361. The paddle 2364 extends from the slide groove 2365. The surface of the inner housing 231 is provided with a locking groove 237, wherein the locking groove 237 and the locking member 2363 are both provided with latch teeth.

Under normal conditions, the two sets of springs 2362 provide mutually separated elastic forces to the two locking parts 2363 respectively, and the paddle 2364 contacts the edge of the slide groove 2365 to limit the two locking parts 2363. At this time, the locking teeth on the locking part 2363 are engaged with the locking teeth on the locking groove 237, and the locking part 2363 is fixed. By connecting the locking part 2363 with the inner housing 231, the inner housing 231 can be rotated by rotating the locking part 2363.

In the specific implementation process, the cover 24 is first opened, and then the paddle 2364 is pinched to bring the two paddles 2364 closer to each other, and then the two locking parts 2363 are brought closer to each other, and the locking part 2363 and the locking groove 237 are eliminated. The meshing connection between the latching teeth. Then the driving assembly 236 is rotated, the driving gear 232 rotates, and the rotation of the gear 232 drives the rack 233 to move. The rack 233 drives the mounting base 234 to extend or retract the inner housing 231, thereby adjusting the position of the roller 235.

During the rotation of the rotor 23, by changing the position of the roller 235, the diameter of the circumferential trajectory of the rotor 23 can be changed. More specifically, if the diameter becomes the maximum diameter of the circumferential trajectory during the rotation of the rotor 23, then the degree of squeezing of the hose 25 is the highest, and at this time, the liquid delivery volume is also relatively large. On the contrary, if the diameter becomes the smallest diameter of the circumferential path during the rotation of the rotor 23, then the degree of squeezing of the hose 25 is the lowest, and at this time, the delivery volume of the liquid is also relatively small.

In this embodiment, the end of the rack 233 away from the mounting seat 234 is provided with a limiting portion (not shown in the figure) to prevent the rack 233 from falling off, so as to prevent the rack 233 from falling off from the inner housing 231 . Although in this embodiment, the liquid delivery flow rate can be changed by adjusting the rotation speed of the motor 21, this adjustment method relies more on the control of the circuit. In contrast, the adjustment method of the mechanical transmission structure has certain reliability issues. Advantage. Therefore, this embodiment provides a structure with higher reliability for 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 will be squeezed by the compressed pipe wall, causing a reaction force to push the liquid along the pipe direction. When the roller 235 rolls over the hose 25, the newly compressed tube wall will return to its original state, thereby sucking in new liquid, and this is repeated to achieve continuous delivery of liquid. It is worth noting that the roller 235 will also rotate itself when in contact with the hose 25. This design can effectively reduce the friction on the hose 25, thereby extending the service life of the hose.

In another embodiment of the present invention, the liquid storage tank 1 is composed of an inner box 11 , an outer box 12 and a cover 13 . The inner box 11 is arranged inside the outer box 12, and a strip-shaped notch 14 is opened in the outer box 12. The inner box 11 is a transparent box with scale lines 15 arranged on it, and the scale lines 15 correspond to the bar-shaped notches 14 of the outer box 12 .

More specifically, medical staff can directly check the amount of liquid in the inner box 11 by observing the strip notch 14 on the outer box 12 . The setting of the scale line 15 enables medical personnel to accurately observe and measure the amount of liquid in the inner box 11 . In addition, the scale line 15 is marked with corresponding volume values, and medical staff can view these values to accurately understand the specific amount of fluid discharged from the patient's abdominal cavity.

This design allows medical staff to monitor the patient's drainage situation in real time and accurately, helping to evaluate efficacy and adjust treatment plans, while also providing patients with more considerate care.

In another example of the present invention, the cover 13 and the inner box 11 are connected in a snap-fit manner. When it is necessary to clean the inner box 11, you only need to remove the cover 13, pour out the accumulated liquid in the inner box 11, and then rinse the inner wall of the inner box 11 with clean water. Next, disinfection and sterilization can be performed. The specific method can be to inject boiling water into the inside of the inner box 11 and use high-temperature disinfection, or directly inject disinfectant into the inside of the inner box 11 for disinfection. The disinfectant can be medical alcohol or other disinfectants.

In addition, the outer box 12 is made of rubber. This material can provide good friction when held by medical staff and prevent the liquid storage tank 1 from slipping from the hands of medical staff. This is because rubber is a material with good damping and grip, and its surface microstructure can produce a certain amount of friction with human skin, thereby increasing grip stability and reducing the possibility of slipping. This design is more user-friendly and improves the safety and convenience of medical staff during operation.

In another example of the present invention, the electric abdominal drainage device further includes a liquid 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 close to full, the liquid level alarm will sound an alarm to remind medical staff to clean the liquid in the liquid storage tank 1 at all times.

The liquid level alarm 4 includes a speaker 41 , a contact switch 42 and a switch trigger assembly 43 . Among them, the speaker 41 and the contact switch 42 are both provided on the cover 13 . The speaker 41 may be an existing small dynamic speaker or a piezoelectric speaker, and its main function is to issue an audible alarm. The contact switch 42 is provided on the lower surface of the cover 13 and may be an existing micro switch or a capacitive touch switch.

The operating principle of the contact switch 42 is based on the switching of current. When the contact switch 42 comes into contact with something (in this case, the switch trigger assembly 43), the switch will close, the circuit will be connected, and the speaker 41 will sound. On the contrary, when the contact switch 42 no longer contacts the switch triggering component 43, the switch will be disconnected, the circuit will be disconnected, and the speaker 41 will no longer make sound.

The main function of the switch trigger 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 where the trigger component 43 is located, the buoyancy of the liquid will cause the trigger component 43 to rise. After the trigger component 43 rises, it will contact the contact switch 42, thus triggering the switch and causing the speaker 41 to make a sound. In this way, the medical staff will be reminded that the liquid in the liquid storage tank 1 is nearly full and needs to be cleaned in time.

In another example of the present invention, the switch trigger assembly 43 includes a tube body 431 , a floating bag 432 and a contact rod 433 . The inner wall of the tube body 431 is provided with an upper limiting part 434 and a lower limiting part 435, and the floating bag 432 is provided inside the tube body 431. The floating bladder 432 can float up and down in the tube body 431 due to the buoyancy of the liquid in the liquid storage tank 1 . The contact rod 433 is installed on the upper part of the floating bag 432, and the tube body 431 is fixedly installed in the liquid storage tank 1, close to the upper part of the liquid storage tank 1.

The floating bladder 432 and the contact rod 433 are usually made of a lightweight material, such as plastic, which is capable of floating in liquids. The contact rod 433 is used to push the contact switch 42 .

Specifically, as the liquid in the liquid storage tank 1 gradually increases, the liquid level begins to rise. When the liquid level in the liquid storage tank 1 rises and enters the tube body 431 , the floating bag 432 will be affected by the buoyancy of the liquid and follow the liquid surface, which will also drive the contact rod 433 to move upward inside the tube body 431 . When the upper end of the contact rod 433 comes into contact with the contact switch 42, the contact switch 42 is triggered to turn on the speaker 41 to make a sound. In this way, the medical staff will be reminded that the liquid in the liquid storage tank 1 is nearly full and needs to be cleaned in time.

The exemplary embodiments of the present application can be combined with each other, and the exemplary embodiments obtained by combination also fall within the scope of the present application.
