Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a drainage device for use after breast surgery. Background Art

[0002] The breast is located between the superficial and deep layers of the superficial fascia of the skin; the superficial fascia extends into the breast tissue to form cord-like lobular septa, one end connected to the pectoral fascia and the other end connected to the skin, fixing the breast gland in the subcutaneous tissue of the chest. After breast benign and malignant diseases surgery, due to the relatively large wound surface and relatively more exudate and bleeding, a negative pressure drainage device is often required to timely drain the accumulated fluid.

[0003] In the process of breast surgery drainage operation, for a negative pressure drainage device, it is mostly achieved through a negative pressure ball, a negative pressure bottle or an artificial push-pull type negative pressure tube. It is connected to the postoperative wound through a drainage tube and then drains by using negative pressure. It is a medical device that guides pus, blood, and fluid accumulated in human tissues or body cavities to the outside to prevent postoperative infection and promote wound healing. However, since the postoperative accumulated fluid may contain blood clots, pus, fibrin, and other impurities, it is easy to cause the drainage tube to be blocked or the drainage efficiency to be reduced, resulting in the drainage tube being unable to perform the drainage operation.

[0004] To solve the above situation, a crushing component is usually set in the drainage tube, but its structure is complex, and during the use of the device, the surface of mechanical components is easily contaminated with pus or fibrin, making subsequent cleaning and disinfection difficult and possibly leading to the risk of cross-infection; or a micro filter screen is set at the inlet of the drainage tube for filtration, but a pile-up situation is also likely to occur on the outside of the micro filter screen, gradually forming a "blocking layer", which affects the speed of liquid entering the drainage tube. Therefore, the present invention proposes a drainage device for use after breast surgery to solve the problems existing in the prior art. Summary of the Invention

[0005] Aiming at the above problems, the purpose of the present invention is to propose a drainage device for use after breast surgery, which has the advantages of simple structure and convenient use, so as to relieve the discomfort of the patient's neck and solve the problems existing in the prior art.

[0006] To achieve the object of the present invention, the present invention is realized by the following technical solutions: A drainage device for use after breast surgery, comprising an I-shaped frame, on both sides of the I-shaped frame, a first connecting member and a second connecting member are respectively installed. Below the first connecting member, a drainage bottle is installed. Below the second connecting member, a negative pressure bottle is installed. The negative pressure bottle is connected to the drainage bottle through a regulation component. On the I-shaped frame, a hard drainage tube is installed. The hard drainage tube is installed with a connecting cylinder through a first drainage hose. The connecting cylinder is installed with a drainage needle through a second drainage hose. Inside the connecting cylinder, a fixing block is installed. On the fixing block, a fan-shaped spiral blade is installed through a bearing, and a number of spherical protrusions are distributed on the fan-shaped spiral blade.

[0007] A further improvement lies in that: The regulation component includes a connecting hose, on which a manual valve is installed, and at both ends of the connecting hose, a first connecting hard tube and a second connecting hard tube are respectively installed. The first connecting hard tube passes through the I-shaped frame and extends into the drainage bottle. The second connecting hard tube passes through the I-shaped frame and extends into the negative pressure bottle.

[0008] A further improvement lies in that: The connecting cylinder is made of a transparent material, and the connection between the connecting cylinder and the first drainage hose and the second drainage hose is a detachable design. At both ends of the connecting cylinder, silica gel connection ports are installed, and on the silica gel connection ports, stainless steel tightening hoops are installed.

[0009] A further improvement lies in that: At the bottle mouths of the drainage bottle and the negative pressure bottle, silica gel nozzles are installed. Between the drainage bottle and the first connecting member, a sealing glue layer is filled. Below the drainage bottle, a fixing plate is provided, and the fixing plate is connected to the I-shaped frame. On the fixing plate, a threaded rod is installed, and at the lower end of the threaded rod, a knob is installed. At the upper end of the threaded rod, a contact plate is installed.

[0010] A further improvement lies in that: The negative pressure bottle is connected to the second connecting member through a thread. Below the negative pressure bottle, a support plate is provided, and the support plate is connected to the I-shaped frame. Above the support plate, a pressing plate is installed through a spring.

[0011] A further improvement lies in that: A digital display barometer is installed on the second connecting hard tube.

[0012] A further improvement lies in that: A pressure relief valve is installed on the connecting cylinder.

[0013] A further improvement lies in that: The surface of the fan-shaped spiral blade is coated with a hydrophobic coating.

[0014] The beneficial effects of the present invention are as follows: The overall structure of the present invention is simple, and a split design is mostly adopted, which facilitates replacement and installation, making it convenient for medical staff to clean and disinfect key components. By using the design of a segmented drainage tube, a connecting cylinder is arranged therein, and fan-shaped spiral blades are provided. The rotation of the blades is driven by the flow of liquid. The spherical protrusions distributed on the surface of the blades generate cutting and rolling effects, breaking large blood clots and fibrin into small particles, preventing them from blocking the drainage tube and keeping the pipeline unobstructed. The entire structure is driven without power and operates automatically by the flow of liquid, avoiding a complex mechanical drive system, reducing the risk of equipment failure, and being easy to clean, reducing the risk of contamination.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] In order to deepen the understanding of the present invention, the following will further elaborate on the present invention in combination with embodiments. These embodiments are only used to explain the present invention and do not constitute a limitation to the protection scope of the present invention.

[0022] After breast surgery (such as breast cancer resection, breast reconstruction), there is often fluid accumulation (blood or lymph fluid) in the surgical area. If this fluid cannot be drained in time, it will increase the risk of postoperative infection and complications, resulting in delayed postoperative recovery.

[0023] The postoperative effusion contains a large number of blood clots, fibrin clumps and pus, which are likely to deposit in the drainage tube. Due to the small diameter of the drainage tube (especially the small-diameter drainage tube used after minimally invasive surgery), blood clots or fibrin clumps are likely to completely block the tube. Once the drainage tube is blocked, the postoperative effusion cannot be discharged in time, which will lead to an increase in the pressure inside the wound, increasing the risks of infection, hematoma or effusion. Therefore, after blockage, it is necessary to replace the drainage tube or perform flushing treatment, which not only increases the difficulty of medical operations, but also causes additional pain to the patient.

[0024] Therefore, according to Figures 1-5 As shown, this embodiment proposes a drainage device for use after breast surgery, including an I-shaped frame 1. A first connector 2 and a second connector 3 are respectively installed on both sides of the I-shaped frame 1. A drainage bottle 4 is installed below the first connector 2. A sealing glue layer is filled between the drainage bottle 4 and the first connector 2. The bottle mouth of the drainage bottle 4 is directly inserted into the inner side of the first connector 2. At this time, the outer side between it and the first connector 2 is filled with the sealing glue layer, and the sealing glue layer is fixedly connected to the first connector 2, and its function is to play a sealing role. At the same time, a fixing plate 19 is provided below the drainage bottle 4, and the fixing plate 19 is connected to the I-shaped frame 1. A threaded rod 20 is installed on the fixing plate 19, and a knob is installed at the lower end of the threaded rod 20, and a contact plate 21 is installed at the upper end of the threaded rod 20. The upper end of the contact plate 21 contacts the drainage bottle 4. In this device, the drainage bottle 4 is connected in a plug-and-play manner, which is convenient for its replacement and installation. Correspondingly, after its installation, the staff rotates the knob by hand, which drives the threaded rod 20 to rotate. The threaded rod 20 is connected to the fixing plate 19 through threads. Then, under the action of the threaded connection, the contact plate 21 is driven to contact the bottom of the drainage bottle 4, so as to generate a supporting and limiting effect on it, ensuring the connection stability between it and the first connector 2.

[0025] A negative pressure bottle 5 is installed below the second connector 3. The negative pressure bottle 5 is connected to the second connector 3 through threads. The negative pressure bottle 5 provides a negative pressure environment. Therefore, by using the threaded connection method, it can provide more stable airtightness, especially in the case where a negative pressure environment needs to be maintained. At the same time, the threaded connection avoids the sealing problems caused by insufficient insertion depth or incorrect position during the plugging and unplugging process. A support plate 22 is provided below the negative pressure bottle 5, and the support plate 22 is connected to the I-shaped frame 1. A pressing plate 23 is installed above the support plate 22 through a spring. During operation, the spring in the contracted state provides a reaction force to the pressing plate 23, prompting it to contact the bottom of the negative pressure bottle 5 tightly, so as to generate a certain pressing force on the negative pressure bottle 5 and improve the connection stability.

[0026] The negative pressure bottle 5 is connected to the drainage bottle 4 through a regulation component. The regulation component includes a connecting hose 13, and a manual valve 14 is installed on the connecting hose 13. In this embodiment, the manual valve 14 is a push-pull type valve, which controls the opening and closing of the connecting hose 13 through push-pull actions, facilitating manual operation by the staff. First connecting rigid pipes 15 and second connecting rigid pipes 16 are respectively installed at both ends of the connecting hose 13. The first connecting rigid pipe 15 passes through the I-shaped frame 1 and extends into the drainage bottle 4, and the second connecting rigid pipe 16 passes through the I-shaped frame 1 and extends into the negative pressure bottle 5. Silicone nozzles are installed at the bottle mouths of the drainage bottle 4 and the negative pressure bottle 5. The silicone nozzles expand when the pipeline is inserted and automatically return to their original state after being pulled out by utilizing their elasticity and shape memory characteristics, thus facilitating the connection of various pipelines. Then, during operation, with the cooperation of the negative pressure bottle 5, the connecting hose 13, the first connecting rigid pipe 15, and the second connecting rigid pipe 16, the device can continuously create a negative pressure state in the drainage bottle 4, thereby achieving a synergistic effect, providing continuous negative pressure at the wound after breast surgery, playing a role in sucking in liquids, and then draining the liquids, collecting body fluids (such as blood, lymph fluid, etc.) discharged from the postoperative wound. In this device, a digital display barometer 24 is installed on the second connecting rigid pipe 16 to facilitate understanding of the air pressure state inside the second connecting rigid pipe 16.

[0027] A drainage rigid pipe 6 is installed on the I-shaped frame 1. The lower end of the drainage rigid pipe 6 passes through the I-shaped frame 1 and is located inside the drainage bottle 4. The drainage rigid pipe 6 is installed with a connecting cylinder 8 through a first drainage hose 7, and the connecting cylinder 8 is installed with a drainage needle 10 through a second drainage hose 9. During operation, the drainage needle 10 is connected to the drainage wound of the patient after breast surgery. Thus, through the continuous negative pressure provided by the negative pressure bottle 5, the negative pressure is transmitted to the drainage needle 10 through the drainage rigid pipe 6, the first drainage hose 7, the connecting cylinder 8, and the second drainage hose 9. Under the action of the negative pressure, the exudate, blood, etc. from the postoperative wound are attracted by the drainage needle 10 and enter the second drainage hose 9, pass through the connecting cylinder 8 and the first drainage hose 7, and finally are discharged into the drainage bottle 4 through the drainage rigid pipe 6. In this embodiment, the drainage bottle 4 is made of a transparent material, and medical staff can observe the volume, color, and properties of the drained liquid in real time and judge the postoperative recovery situation accordingly.

[0028] A fixing block 11 is installed inside the connecting cylinder 8. The fixing block 11 is connected to the inner wall of the connecting cylinder 8 through a bracket. A fan-shaped spiral blade 12 is installed on the fixing block 11 through a bearing, and a number of groups of spherical protrusions are distributed on the fan-shaped spiral blade 12. Specifically, the fan-shaped spiral blade 12 is designed by imitating a fan, that is, it is composed of a number of groups of blades to form a fan-shaped spiral blade 12. The fan shape can better break and decompose fibrous or gel-like blood clots. Its blades are radially distributed with the axis as the center and are evenly arranged outward from the central axis. During the drainage process, the rotation of the blades is driven by the liquid flow. Thus, during the rotation process, in cooperation with the spherical protrusions, a cutting and shearing action is generated. Therefore, the shear force and impact force generated by the rotation of the blades are used to break the blood clots to avoid the situation of pipeline blockage during the postoperative drainage process. Further, the surface of the fan-shaped spiral blade 12 is coated with a hydrophobic coating to reduce the occurrence of foreign matter adhesion.

[0029] The connecting cylinder 8 is made of a transparent material, and the connecting cylinder 8 and the first drainage hose 7 and the second drainage hose 9 are designed to be detachable. Specifically, silicone connecting ports 17 are installed at both ends of the connecting cylinder 8, and stainless steel tightening hoops 18 are installed on the silicone connecting ports 17. In this device, a split design is adopted to facilitate the replacement and cleaning of components, that is, when a single component has a problem, there is no need to replace the whole component. At the same time, a pressure relief valve 25 is installed on the connecting cylinder 8. In this embodiment, the pressure relief valve 25 is manually controlled. Under normal conditions, the valve is pressed by a spring or other mechanical structure, and the negative pressure is maintained in the sealed state. When relieving pressure, it is manually operated by medical staff to release the pressure and allow external air to enter the system to prevent liquid backflow when the drainage tube is pulled out or the drainage bag is replaced.

[0030] In this embodiment, regarding the connection methods of various pipelines, they are all detachable connection methods, that is, pipeline connectors are installed at both ends of the pipelines not specified.

[0031] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art of this industry should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention.
